T @ZZ wiz/0717, t may concern:
Be it known that I, HEMAN OsBoRNE, a citizen of the United States of America, and a resident of Springfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Transom-Lifters, of which the following is a full, clear, and. exact description.
An object of this invention, for improvements in devices for opening transoms, and blinds or shutters, is to provide an operating mechanism of the class indicated which is eX- tremely simple, as regards the components thereof, and their assemblage in coperative relations, and which is capable of operating easily and smoothly and another obj ect is to provide a transom or shutter operating mec-hanism which is reversible,-that is as well applicable for operation at the right as the left of a transom or shutter, rendering unnecessary the production of some of the ap# pliances especially designed as rights and the production of others thereof especially designed as leftsl Other objects and advantages are attained in and by the organization, or combination, and arrangement, and the construction of the parts as hereinafter fully described and set forth in the claims.
The improved transom operating device is illustrated in the accompanying drawings, in which,-
Figure 1 is a front elevation thereof, the supporting frame being shown in vertical section and the inclosing casing is represented in dotted lines. Fig. 2 is an elevation of the same as seen at right angles to Fig. 1,-portions of the frame and inclosing casing being shown in vertical section, as taken on the line 2 2, Fig. 1. Fig. 3 is a horizontal sectional view as seen on line 3 3, Fig. 1,-the
worm wheel and shaft being, however, shown in plan view. Fig. 4 is a perspective view of the supporting frame. Fig. 5 is a perspective view of the iuclosing casing, and Fig. 6 is a perspective view showing the operating device as applied in its relation to the transom.
Similar characters of reference indicate corresponding parts in all of the views.
In the drawings,-A represents the frame or support which may be lof any suitable metal and design, the same, as shown, comprising a back wall 1G, opposite side walls 12, 12, and a front wall 13, the same being bent or formed in rectangular shape; and the back wall is provided with screw holes whereby the frame may be screwed to the.
shaft B has necked` down journals or gud geons 15 and 16, the shorter one 15 being engaged in a circular journal hole 17 therefor in one of the frame sides, while the longer jour nal 16 is passed through a larger hole 18 receiving a bushing or annular plug 19 before the transom operating arm D is fastened on the extremity of the worm wheel shaft.
F represents another shaft horizontally journaled in a line at right angles to and above the worm wheel shaft, the same having necked down end gudgeons 20, 20, which are fitted in circular journal holes 22, 22, in the front and back of the frame. The said shaft F has a worm G intermediately formedthereon which meshes into the worm .wheel C; and the said worm shaft F also has integrally formed or afliXed thereon a spur gear wheel H at its end portion near and inside of the back wall 10 of the frame.
J J represent oppositely located rack bars, oppositely in mesh, by their inwardly facing teeth, with the said spur gear wheel on the worm shaft; and said rack bars are slidable vertically within and through the frame.
Guides and means for restraining the rack bars against lateral displacement are constituted by lips or lugs 23, 23, which may be struck-up"7 from portions of the opposite side walls 12, 12, of the frame adjacent but separated from the back wall; and the back wall, and also the opposite side walls may have internal bosses or inwardly displaced portions 24, 24, to serve as bearings at widely separated parts for the back and side of each rack, and lessening the friction between the racks and the walls of the frame.
The transom operating arm D has at its lower end portion a split hub or collar b with ear pieces d at either side of the cleft engaging with which is a constricting screw and thus the armA d is reversible on the worm wheel shaft and may be turned end for end accordingly as the device as a whole is applied as'a right or left hand appliance in relation to a transom.
The rack bars which are of considerable IOO IIO
length, and extend both above and below the frame, have eyes at both ends thereof and chains h or like fiexible connections are secured to and depend below the lower eye formed ends of the racks, and serve as means within convenient access for operating either one of the racks accordingly as the transom is to be opened or closed.
j represent duplicated springs operable against the rotary movement of the worm wheel shaft in a direction corresponding with the swinging movement in the opening direction of the transom, such springs, preferably duplicated as stated, being effective by their reaction to compensate for or counter the stress brought against the worm wheel shaft by the opening or opened transom, more especially in cases where the transom is pivotally 'hung at its lower edge and swings from above such edge 3 an d in the present instance for cooperation with the said springs are cams 'm m integrally formed or affixed on the worm Wheel shaft at opposite sides of the worm wheel.
Vhen the worm wheel shaft has a degree of rotation imparted thereto to swing theA transom open, the eccentric portions of the cams are crowded against and deflect, and increase the tension of the springs, counterbalancing the gravitative force exerted on the mechanism by the transom; and by having the cams and springs duplicated, with means for adjusting the springs for changing the tension thereof, the mechanism may be regulated to be sensitive in operation in relation to either heavy or light under pivoted transoms.
As shown in Fig. 2, the springs j have rounded ends which are substantially pivotally engaged or fulcrumed within the partially circular turned portion 30 of the back of the frame; and as a means for varying the tension of the springs, screws 32 have thread engagements through the springs, and their projecting rear ends constitute adjustable shoulders in bearing against the frame back.
L represents a sheet metal inclosing casing or housing for the frame and mechanism supported by and inclosed therewithin,-said casing having ear lugs 35 through which, by screws, the casing is affixed on the same support as the frame. The said casing is provided with suitable recesses and a ertures to give play to certain of the movab e parts, as apparent. This mechanism is equally operable either end up, and in a case where it is necessary or more convenient that the same be employed at the right hand side of a door and transom casing instead of at the left hand side, as shown in Fig. 6,-it is only necessary to mount the device in its position endwise reverse from that shown in Fig. 6, so that the arm carrying end of the worm wheel shaft will project to the leftward instead of to the rightward, reversing the position of the transomA operating arm D on the worm wheel shaft, and hanging the chains on the depending ends of the rack bars.
