6 Claims. 1

This invention relates broadly to closure devices and has particular reference to a means associated therewith for actuating the closure device to either a closed or open position under the influence of a rain detector and is an improvement over our co-pending application, Serial No. 300,461, filed July 23, 1952.

The invention has for itsprime object the actuationof a closure device, such as the conventional jalousie windows of the type that are shifted to a closed or open position by a single stroke actuating bar. The device of the present invention is adaptable for various other types of windows, such for instance, as casement windows or, with slight modifications, the device is adaptable for the operation of the conventional doublehung windows. The device contemplates automatically controlled mechanism that is associated with the operator bar of the window in conjunction with an electrical connector of the type commonly known as a rain-detector coupled with means for permitting an actuation of the window exclusive of the rain-detector by a remote control switch.

A further object of the invention resides in novel mechanical means to permit the manual shifting of the closure device to either a closed or open position exclusive of the'electrical means, which is most desirable inthose infrequent intervals when thereis an electrical failure and current is not available for the device of this invention.

The invention further contemplates novel adjustable means for controlling the movement of the window operator bar to its maximum shifting position for a fully closed or open position of the window.

A further object of the inventionresides in a novel clutch mechanism for disconnecting the electrical drive means so as to enable the manual shifting of the window in the absence of electricity.

Various other novel structural details will be more clearly apparent during the course of the following description, reference being had to the accompanying drawings, wherein has been illustrated a preferred form of the device and wherein like characters of reference are employed to denote like parts throughout.

. Figure 11 is a diagrammatic illustration of an electrical control wiring associated with the device.

Referring now more specifically to the drawings and particularly to Figures 1 and 2, a conventional jalousie window has been fragmentarily illustrated for purposes of illustrating the opera- The window includes the usual frame 5 that supports a plurality of closure panels 6 to be simultaneously swung on their horizontal pivots I through the medium of a common operative bar 8. This type of window embodies either metal, wood or glass louvers, andthe operating means for the louvers in this particular instance is of the type recognized as a single throw crank or lever that normally projects through an opening 9 in one side jamb Hi. Other types of jalousie windows are operative through the medium of winding operators, commonly referred to in the copending application identified. The window may support the usual insect screen I! without interference with the device of this invention, the screen being readily removable without interfering with the mounting of the invention. Fixedly supported upon the outer side of the frame 5 and preferably in the area of this invention, is an electrical connector of the type that is actuated by a single drop of water, the rain-detector being indicated as a whole by the numeral l2 in Figures 1 and 9. The rain-detector l2 will be more clearly described later.

The device of this invention is supported within a rectangular housing l3 having a removable cover I4. Cover I4 is apertured at I5 for the passage of an arm It embodied within a toggle switch H, and serves as a remote control means for the control of the window. The cover I4 is further slotted at I8 for the insertion and shiftable movement of a flat crank it of generally L-shape, the operation thereof to be later described. The cover I i has been stamped or embossed adjacent the toggle It to indicate an open or closed position of the mechanism.

Supported within the housing |3 in any desirable manner against displacement, is a metallic frame 26 that rigidly supports, as by screws 2|, a series wound reversible type electric motor, indicated as a whole by the numeral 22. With the housing arranged in a vertical manner as shown, the motor will likewise be vertically disposed. The motor is provided with a drive shaft 23. Since the motor 22 forms no part of the present invention, its structure will not be described in detail other than to generally indicate a field winding 24 and armature 25 and the usual brushes 26 and 21. It might be pointed out at this time that the flow of current through the field windings 24 is in one direction, while the rotation of the motor is reversed by a change of polarity on the brushes 26 and 21 through the medium of a novel reversing switch, to be later described. A source of electrical energy is conducted from any convenient adjacent outlet in the building through a cable 23. A conventional equipment ground 29, shown in Figures 3 and 11, is employed as a protection against any possible shortage in the electrical system. The shaft 23 is journalled in a bearing of any desirable form 30 and extends through an opening in the frame to terminate in a gear housing 3|. splined or otherwise fixedly connected with the end of the shaft 23 is a worm 32. The worm 32 in turn meshes with a worm gear 33, splined or otherwise fixed upon a shaft 34, journalled at its lower end in a bearing 35 and at its upper end in a suitable bearing carried by a removable cover-plate 36. The cover-plate 36 is detachably connected to the gear housing 3| by screens or the like for easy removal and to facilitate the assembly of the gear 33 and its shaft. Below the gear 33, the shaft has also splined thereon a worm 3'! having meshing engagement with a worm gear 38, pinned at 39 upon a cross shaft 46. bearings 4| carried by the opposite walls of the gear housing 3|. The shaft 40 projects beyond the side wall 3 I to a point closely adjacent a side wall of the housing [3 for the reception of louver actuating mechanism, to be described. The drive from the motor 22 to the shaft 40 is of a novel reduction type that imparts a very considerable torque to the shaft 40 and permits the assembly of the gearing within a minimum space. It is contemplated that the frame 23 and housing 3| shall be cast as an integral unit. The housing 3| is provided with a cover-plate 42 to facilitate access to the housing 3| for the introduction of lubricants and facilitate the assembly of the shaft 40 and the gear 38. extended outwardly as at 43 and serves as a rigid mounting for a reversible type toggle switch 44, having a toggle arm 45 that projects beyond the housing 3|. in substantial alignment with the shaft 46 and lies within the path of actuating mechanism, to be described. The extension 43 likewise serves as a mounting support for a plate 46 that serves as a rigid mounting for the toggle switch thus permitting the removal of the cover |4 without disturbing the switch since the cover may be easily removed after the conventional locknut of the switch is first removed.

The housing l3 and its encased frame 20 and associated elements are rigidly connected to the inner face of the jamb ID in the position commonly occupied by the conventional jalousie operator and the base of the frame 20 has been drilled for the passage of screws 41 that are spaced apart a distance corresponding to the spacing of the screw openings that normally sup- The shaft 40 is journalled in suitable The housing 3| is further 5 port the conventional operator. The frame base is further extended and projects through an opening in the housing l3, as shown at 48, and this extension is likewise drilled for the passage of screws 49 which likewise are spaced and positioned to correspond with the conventional screw openings of the jamb I0. In this manner it only becomes necessary to remove the conventional operator and substitute the device of this inven tion, requiring no cutting or additional drilling and tapping of the jamb. This particular mounting is common to the major number of conventional operators.

Referring now articularly to Figures 2, 4, 5 and 8, the numeral 5|] denotes the actuating mechanism as a whole that is employed to automatically shift the operating bar 8, or to shift the operating bar 8 by the manual control crank l9; The mechanism embodies a hub 5| having an enlarged cylindrical head 52 that is recessed upon its outer face as at 53 for the seating reception of a clutch disc 54. The head 52 is provided with a preferably integral tubular crank arm 55 that is at right angle to the hub 5| and which normally is positioned slightly inwardly from one inner side of the housing I3 and its cover l4. Likewise formed integral with the head 52 is an angularly disposed crank arm 56 pivotally connected at its terminal end, as at 51, with a link 58. The link in turn at its opposite end is pivotally connected with the operator bar 8, as at 59. The hub 5| is further reduced in diameter to form a hub extension 60. Inwardly of the recess 53 of the head 52, the hub is provided with a relatively dee cylindrical recess 6| for the reception of a cylindrical hub 62 formed upon the clutch disc 54. The recesses 53 and 6| are axially disposed with respect to the hub 5| and concentric thereto. The hub 5| and its reduced extension are further provided with an axially arranged cylindrical bore 53 for the mounting and rotatable support of the hub 5| upon the extended portion of the shaft 40. A thrust washer 64 is disposed between the inner end of the hub extension 60 and the adjacent side wall 3 of the gear housing, clearly shown in Figure 4. The disc 54 and its hub 62 are bored and splined for splined engagement upon the outer end of the shaft 4|], as shown at 65. The inner face of the head 52 is provided with a pair of oppositely arranged lugs 66 threadedly supporting adjusting screws 61 for use in a manner to be presently described. The clutch disc 54 is apertured at equidistantly spaced points 68 for the reception of a clutch pin 69 that is shiftable in an opening 10 that extends entirely through the head 52. The pin 69 is normally urged into engagement within either of the apertures 68 under the in-. fluence of a preferably leaf spring 1|, rigidly connected as by screws or rivets to the inner face of the crank 55 as at 12. Theinner face of the crank 55 has been cut away, as at 13, to permit alower angular extension of the spring H to normally lie against the inner wall of the forward face of the crank 55, in which position the pin 69 has been projected forwardly to engage in either of the apertures 68. Since the clutch disc 54 and its hub 62 are splined to the shaft 40, the shaft 46, clutch disc and the hub 5| and associated housing 52 are securely locked together by the pin 69. If for any reason there is a failure of the electric service, the operator may release the clutch connection by inserting the crank l9 through the slot I8 and downwardly into the tubular crank 55, where it will contact the spring 'II and shift it laterally, withdrawing the pin69 from the aperture 68, thus permitting the operator through the medium of the crank I9, to shift the crank 55 and its associated crank 56 freely upon the shaft to close or open the louvers. Upon removal of the-crank I9, the spring II will tend to shift the pin 69 towardsthe disc 54 and, upon an actuation of the mechanism by the electric current, the first motion of the shaft 40 -will naturally rotate the disc 54 and immediately that an aperture 68 registers with the pin 59, it will become locked together again. It should be -un-. derstood, however, thatthe use of the crank I9 is only for emergency purposes in the event of an electrical power failure and normally is sup ported at some point convenient to the operator. The slot I8 is of a length that permits the maximum swinging motion of the crank 56 since there may be some slight variation in the thrownecessary to open and close louvers in windows of different manufacture.

Themeans to throw thetoggle arm to either rotatable mounting upon the hub extension fifl;

The disc I4 is extended upwardly and offset outwardly, as at T6, and with the offset I6 being arcuately apertured at 11. The toggle arm 45, as clearlyshown, projects through the arcuate opening 11. The opening 11 is on an'arc struck from the axial center of the shaft 40. It will thus be apparent that when the disc I4 is rotated, through means to be presently described, the end wall of the arcuate opening 11 will engage and shift the arm 45 laterally, such motion and such engagement depending on which position the toggle arm 45 is in when the mechanism is actuated. The offset I6 has been made as a means to permit theassembly of the mechanism in a minimum space. The means for rotating the disc I4 consists of a disc I8 that is apertured at I9 for rotatable support upon the hub GO- and normally abuts the shoulder formed by the hub 5I. The disc i8 is positioned upon the hub extensionzfiflbetweenthe hub 5| and the disc I4. The lugsBIl formed upon the disc '18 are disposed beneath the lower ends of the adjusting screws 61. Thus, a rotation of the hub 5| through the medium'of theclutch 54 willbe transmitted to the disc 18 at the moment of contact between either of the screws 61 and its adjacent lug 80. Movement'of the disc I4 is through themedium of alateral extension 8i formed upon the disc I8 and normally projecting through an arcuate and concentric slot 82. The extension 8I is aperturedfor threaded engagement upon a compression spring- 83 that is positioned within the slot .82. The connection of the extension 8| with the spring 83 is substantially intermediate the ends of the spring. The opposite ends of the slot 82 are provided with lugs 84 that will successfully preyent the disengagement of the spring from the slot. It will thus be apparent that upon rotation of the aforesaid mechanism as described with "respect to the disc 18, the extension BI will first tend to compress the spring 83 in the direction of rotation. However, since the spring is relatively strong, the disc 14 will freely rotate until the end of the slot I? contacts the toggle arm 45 and the spring 83 is sufiiciently strong that the toggle arm will be thrust to a reverse position without unduly compressing the spring in either direction, depending on which direction the disc is being rotated. Stop screws 85 limit the motion of the disc 14 to the extent necessaryito throw tit) the toggle arm '45 to either of-lts limits of motion without damaging the switch. Since the rotation of the disc I4 will be stopped at its maximum throw, any tendency of the mechanism to coast will be absorbed by the spring 83 in either direction of possible coasting. The use of the adjusting screws 6? permit an easy and accurate adjustment for controlling the throw of the crank 56, thus permitting the crank 56 to be shifted to a 'maximum travel both for opening and closing the window, and with the screws 6'! adjusted so as-to contact the lugs 80 at the proper moment to rotate the disc I4 as the crank 56 approaches the fully closed or open position of the window. The screws 61 are adjusted by the installing operator by removing the cover I4 and afterhe has determined the degree of movement necessary for the crank for a complete opening and closing of the window. The discs I4 and I8 are maintained upon the hub by a washer 86 that preferably has a press fit upon the terminal endof the hub extension 60, with the discs I4 and I8 being slightly spaced apart for freedom of movement. Supported upon the base of the frame '20. as by screws 8?, is a relay 88 and associated elements embodied within the electrical control means for the device.

Referring to Figures 9 and 10, a tubular casing 89 is supported upon the exterior face of thejamb pin through the medium of a bracket 90, preferably of porcelain or other non-conducting material. The casing 89 is aperturedon its to and bottom as at iii to permit the entry of water to the casing to be subsequently discharged through the bottom. A pair of electrical contact elements 92 and 93 are supported within the casing 89 in spaced relation to the casing and in spaced relation to each other. Electrical conductors 94 and 95 lead from the contacts 92 and 93 through a suitable preformed opening in the jamb I0 for suitable connection to the switch 44, and to the relay solenoid 96. A resister 91 is positioned in the conductor 95 forobviousreasons, see particu-v larly Figure 11. The switch 44 is of the double pole, double throw type and is shown diagrammatically in Figure 11. The motor 22, its field windings 24 and brushes 25 and 21 have been illustrated diagrammatically in Figure 11, as is also the toggle switch 44. The toggle switch 44 I embodies center binding posts 98 and 99 and binding posts I00, IOI, I02 and I03. A conductor I04 connects the binding posts MI and I02 for a purpose to be presently described. The binding post IllI is connected with one side of a source of electrical energy through a conductor I05. The opposite side of the source of electrical supply is connected to one side of the field windings 24 by a conductor I06, while the oppositeside of the windings is connected through aconductor I 07 teens spring contact arm I 08 of the relay 88. The binding post 98 is connectedwith the brush 2'I by a conductor I09, while the opposite binding. post 99 is connected with the brush 26 by a conductor I ID. The binding ost I00 is connected with a binding post III of the remote control switch II, by a conductor I I 2. The binding post I02 is connected to one metallic contact 93 of the rain-detector by the conductor 94. Binding post I03 is connected to a binding post II3 by a conductor H4. One binding post II5 of the switch I? is connected to the negative side of the source ofelectrical energy by a conductor I I6 and opposite-center binding post II! is connected to a spring contact I I8 of the relay 88 by a conductor I19. A shiftable spring contact. I20 embodied in the relay is connected to the contact III by a conductor I2 I. The opposite side of the solenoid 95 is connected to a contact I22 of the switch I! by a conductor I23.

The operation of the device is as follows:

Assuming that the mechanism has been installed, as indicated in Figures 1 and 2, and that the louvers 6 are presently in the closed position, either due to manual control or due to the presence of water in the rain-detector I2, and that theswitch 44 has been shifted to the position for clockwise opening while the switch IT is in a position for automatic operation. Now, if the raindetector is cleared of water, the contacts 92 and 93 are open. This condition deenergizes the solenoid 96, permitting the spring torque I08 to assume the position shown in Figure 11. For purpose of differentiating between the rotation of the motor for either the closing or opening, we shall assume that the clockwise position of the switch 44 is the position for opening and the anti-clockwise position is the position for closing. This motion is obviously determined by the gears between the motor and the actuating shaft 40. This condition now prevailing, current flows from the positive side of the source of current through conductor I tocontact IOI, through conductor or bus bar I04 to contact I02, across the leg of the conventional switch arm shown in dotted line to contact 99, conductor I I0, brush 26, armature 25, brush 2I, conductor I09, contact 98, contact I03, conductor II4, contact II3, contact III, conductor II9, through relay arms II8 and I08, conductor I0'I to the field windings 24 and then through conductor I08 to the negative side of the source of current. The motor 22 is thus energized and drives through the train of gears 32, 33, 31 and 38 to rotate the shaft 40 in a clockwise direction. This rotation of the shaft 40 will rotate the head 52 through the medium of its clutched engagement between the clutch disc 54 and the clutch pin 69. The crank 55 is thus shifted in a clockwise direction and the integral crank 59 is likewise shifted in a clockwise direction, pulling upon the link 58 and causing the operator bar 8 to shift downwardly to simultaneously open all the louvers. At or near the full open position of the louvers, the right hand screw 61 will contact its adjacent lug 80 carried by the disc I8, rotating the disc in a clockwise direction and, through the medium of the lug 8I, the spring 83 is partially compressed, causing the disc I4 to rotate clockwise to shift the toggle arm 45 to the right, which action interrupts the flow of current to the motor and disposes the legs of the switch in the reverse position to bridge the contacts 99 and I00 and 98 and IOI. The moment of actuation of the disc I4 is readily determined by the actuating screws 61 which have been previously adjusted in accordance with the degree of throw of the crank 56 necessary to fully open or close the louvers. Any motion beyond the full actuation of the switch 44 will be absorbed in the spring 93, since the screws 85 have been adjusted to positively limit the arcuate motion of the disc I4. Thus, the spring 83 is an added safety measure against possible damage to the mechanism.

Now, since the device is set for automatic operation by the switch II, should a drop 01 water enter the rain-detector and bridge the contacts 92 and 03, current will flow through conductor I05, contact IOI, conductor I04, contact I02, conductor 94, contact 93, contact 92, conductor 95, solenoid 9B, conductor I23,'contact I22, contact II5, conductor II6 to the negative side of the current, energizing the solenoid 96 and causing the spring arm I08 to shift to contacting engagement with'the arm I20. Current will now fiow through conductor I05, contact IOI, contact 93, conductor I09 to brush 21, through armature 25, brush 26, conductor IIO, contact 99, contact I00, conductor II2, contact III, conductor I2I, through relay arms I20 and I08, conductor I0I to the field windings 24, conductor I06 and back to the negative side of the source of current. Since the polarity has thus been reversed, the motor 22 will rotate in an anti-clockwise direction for an anti-clockwise rotation of the shaft 40 and, through the medium of the clutch disc 54, the crank arms 55 and 56 will shift in an anticlockwise direction, shifting the bar 8 upwardly through the medium of the link 58 to simultaneously close all the louvers. The anti-clockwise motion of the head 52 will cause its adjusting screw 81 on the left side to contact its adjacent lug 80, rotating the disc I8 anti-clockwise and through the medium of the lug BI and spring 83, cause the disc I4 to rotate in an anti-clockwise direction to shift the toggle arm 45 in the re-. verse position or in the position for disposing the switch in the position as first described, which action interrupts the flow of current to the motor 22. The motor will remain inactive so long as current continues to flow through the solenoid, due to the presence of water in the rain-detector I2. It should be herenoted, that when there is an absence of water in the rain-detector, the louvers have been opened and all parts are deenergized. By actual tests, a drop of water is suflicient to actuate the mechanism to close the louvers and, if no more water enters the raindetector, the single drop will boil off in approximately three minutes, when the solenoid is deenergized and the parts are immediately activated to open the louvers.

In rare instances where there may be a failure of the electrical energy and it is desired to either open or close the louvers, the operator merely inserts the flat crank I9 through the slot I8 to engage in the tubular crank 55, which action shifts the spring II to the dotted line position shown in Figure 4, axially shifting the clutch pin 69 from its engagement in an opening 68 of the clutch disc 54. The crank arm 55 may now be freely swung in either desired direction free of the clutch disc 54, since the clutch disc 54 and shaft 40 are locked against rotation, due to the worm and worm gear drive assembly. Thus, the louvers may be manually controlled at any time exclusive of the electrical means. After the manual operation, the crank I9 is removed and upon the re-energizing of the mechanism, the disc 54 will obviously rotate and again become automatically clutched to the head 52 when one of the apertures 88 registers with the pin 69.

Under normal conditions, should the operator desire to actuate the mechanism to the exclusion of the rain-detector I2 in order to close the louvers, it being assumed that the switch 44 has been shifted to bridge the contacts 99 and I00 and 98 and NI, the switch I! is shifted by the toggle arm I6 to bridge the contacts III and Ill. Current will then flow through conductor I05, contact IOI, contact 98, conductor I09, brush 21, armature 25, brush 28, conductor IIO, contact 99, contact I00, conductor II2, contact III, contact III, conductor II9, through relay arms II8 and I 08, conductor I01, field windings 24 and con- 1 ductor I 06 back to the negative side of the source 9 of current, actuating the motor to rotate the shaft in an anti-clockwise directiontoshift the crank arm 56 ina direction to-move the bar 8 upward for simultaneous closing of the several louvers. After thelouvers have beenclosed, the operator shifts the togglearm 16 in the reverse direction or open position asindicatedon the cover I4, when all parts: are in their .normal position for automatic operation under theinfluence of the rain-detector. vSince the closing-of the louvers under theinfluence of the remote control switch I! has shifted the switch 44 to the opposite position to bridge the contacts 99 and I02 and 98 and I03, movement of the toggle arm back to the open position will resetthe circuit fornormal opening of the louvers and immediately that the switch 11 iseshifted' to. open position, the motor will be energized to open the louvers,aassuming of course, that'no water ispresent inthe rain-detector. Should water be present in the rain-dete.ctor,.the. parts will remain inactive. So long as the toggle arm 16 remains'inithe closed positiomthe motor will remain deenergized.

.It will be apparent from the foregoing that .a verysimplexand highly effective mechanism has been providedfor controlling the closuredevice against unexpected .rains. The automatic features' are relatively simple in design and of such characterxthat theyzcan be encased in a relatively small housing and attachedto the window frame in a simple manner requiring no alteration of the window structure. The electrical-system maybe connected 1 to .a convenient wall receptacle in windows already installedhut in newinstallations, provision will bev made in a manner common in the industry. .The device in its operative position has a pleasing appearance and is of such size that it offers no interference to thefree operation .of the conventional Venetian blinds. The adjustment for the throw of the operating crank for the louvers is simple and requires only that cover be removed from the housing I3, after which the simple adjustment is made with. a screw-driver. A single rain-detector may beemployed to control a group of windows, thus simnovel remote control switch wherebytthe operator may close the windows electrically to the exclusion of the rain detector. Theidevice of this invention is particularly adapted to that type of closure employing aplurality of. simultaneously shiftable louvers requiring but a single stroke for either the opening or closing, and the structure is such that it can readily be adapted to the well known casement type windows. The device'further lends itselfto modifications that will adapt it to the double-hung windows. The driven elementsifromrthe shaft 40 are outstandingly novel, are simple, strong, durable, cheap to manufacture and assemble and serve'tolcontrolthe opening or closing of thelouvers in a very unique and positive manner. The electrical wiring system is simple and incorporates therein thosedesirable well known elements, such as the motor, the switches, the relay and the equipment ground wire 29, all being conventional and assembled into the essential combination shown.

Attention is directed to the fact that the resistor 91 is installed-in theline 95 as a means to delay. too quickly an action of the mechanism when the rain detector is too quickly cleared. 'The resistor-has been-calculated to cause the' device to 10 remain inoperative for several minutes since the single .drop of water necessary to actuate the rain-detector will not boil off as rapidly, due to thelow voltage, passing through the points 92 and 93.

While a preferred form of the device has been illustrated and described, various structural changesarecontemplated as readily fall within the'spiritof.therinvention or the scope of the subj oined claims.
