' 4 Claims.
an improved device of this kind which cannot be operated by unauthorized persons since there are included no elements the successful operation of which can be detected by touch, feeling or hearing.
Still another object of the present invention is to provide an improved device of this kind which is simple in construction, easy to manufacture, and reliable in operation.
" Other objects will be in part obvious, and in part pointed out more in detail hereinafter.
The invention accordingly consists in the'features of construction, combination of elements and arrangement of parts which will be exemplifled in the construction hereinafter set forth and the scope of the application of which will be indicated in the appended claims. h
In the accompanying drawing, wherein is shown, for illustrative purposes, several embodiments which the present invention may take,
Fig. 1 is a perspective view showing, more or less diagrammatically, a device constructed according to the present invention;
1a is a detail view showing one of the disks and a' portion of the casing;
Fig. 2 is a side elevation of a drive means for one of the disks;
Fig. 3 is a schematic view showing another embodiment of the present invention;
Fig. 4 is a perspective view of one of the slides shown in Fig. 3; and
Fig. 5 is a side elevation, partly in section, of another embodiment of the present invention.
In order that the detailed description set forth hereinafter may be more clearly and readily understood, it may be stated that the present invention broadly includes a source of light I0, the rays of which are adapted to fall upon a light sensitive element l I Interposed between the source of light and the light sensitive element are a plurality of differentially movable elements l2 which are adapted in all positions, except one predetermined position, to intercept the rays of light from the source of light in order to prevent the same from falling upon the light sensitive element.
Referring more particularly to the drawing, the source of light I0 is illustrated as being governed by a battery I3 and a switch M. The light sensitive element ll visshown in the drawing in the form of a photo-electric cell which is connected 1932, Serial No. 601,764
to a vacuum tube amplifier it which, in turn, may, for instance, be connected to an electromagnet having a solenoid or coil l 6 and an armature I6. The electro-magnet may be suitably connected to a bolt of a lock or the armature It may itself constitute the bolt or locking means. In the present illustrative disclosure, the armature I6 is shown as constituting a bolt which cooperates with a strike plate or keeper 16'. The bolt is normally urged into locking position by 10 a spring I00 located between the bolt and an abutment member 10 I. When a ray of light falls on the light sensitive device I l the coil I6 is energized and the bolt is withdrawn against the pressure of the spring I00. Electro-magnetically op- 5 erated locks are illustrated in Patent No. 178,382
to H. L. Roosevelt, patented June 6, 1876 and in Patent No. 608,321 to H. G. Carleton, patented August 2, 1898. In Figs 1 and 1a, the difierentially movable elements are illustrated in the form 20 of disks l2 loosely mounted upon a shaft l'l sup ported by a casing l8 which may enclose the control mechanism or may, for instance, be a safe or vault to which the device is applied. The disks I2 are disposed within the casing I8 and a portion of the periphery of each disk protrudes outwardly beyond the casing so that the disk may be rotated from the outside of the casing These disks l2 have their peripheral edges graduated, as at l9, to cooperate with a fixed indicator. 20 on the front wall of the casing. Each disk is provided with a blank portion and an open portion 2! which may be a round aperture, a slot, a recess,
or of any desired shape, and these openings 2| are adapted to be brought into registry with one another and with the source of light and the light sensitive element.
Disposed in front of, and spaced from these disks are a series of lenses 22 for bringing the light from the source of light to a focus in the plane of each disk. The use of these lenses is optional since their purpose is to increase the quantity and intensity of the light passing through the apertures in the disks.
vThe operation of, the apparatus described is briefly as follows: It is understood, of course, that the combination (that is, the relation of the openings in the disks to the indicating means on the peripheries of the disks) is known only to authorized persons. Assuming that the positions of the disks are such that the openings thereof are not on a line between the source of light and the photo-electric cell, and in which case the photo-electric cell circuit is open and that it is desired to close said circuit each of the disks (the light having been turned on) will be rotated to a position where the selected or predetermined mark on its periphery is in registry with the associated pointer or indicating mark on the casing. When this is done in accordance with the predetermined combination at which. the control mechanism has been set to operate, the openings are all brought into alignment between the source of light and the photo-electric cell. When the ray of light strikes the cell, the latter is affected so as to result closing the photoelectric cell circuit to energize the solenoid it which in turn will operate whatever device the control mechanism is associated with, for in stance, the bolt of a lock. When it is desired to break the combination, this may be done by turning any one of the disks so that the passage of light from the bulb it to the photo-electric cell is obstructed. By preference, all of the disks will be disturbed in order to make it more difficult for any one to surreptitiously determine the combination. It will be observed that, aside from the markings on the disks, there is no way of determining, either by touoh, sight or hearing, when any one of the disks has been brought to a position Where the opening therein is properly locatecl between the light and the photo-electric cell. In the embodiment shown in Fig. 1 there is no clicking, picking up of an additional ele ment or dropping of an element which might lend assistance to unauthorized persons in determining the combination. Each disk has an infinite number of angular positions, but it is only in one combination of positions that the light can pass from the bulb to the photo-electric cell. Even the most expert locksmith or cracksman cannot possibly pick my improved arrangement or determine what the combination is by manipulating the disks.
In Fig. 2 is shown a different construction for moving the differentially movable elements or disks. In this case, each of the disks if is spaced inwardly-from the front panel of the casing it, and is provided with a miter gear 23. The casing l8 rotatably carries a shaft 2d which extends therethrough and beyond each side thereof. The inner end of the shaft 24 is provided with a miter gear 25 which is constantly in mesh with the miter gear 23 on the disk if. The outer end of the shaft 24 is provided with an operating knob 26 and the dial 21 which may be similar to the dial used on safe looks. The shaft 24 is provided with a collar 24a adapted to seat in a recess in an element 24?) secured to the rear face of the front panel of the casing 8 to prevent the shaft 24 from being pushed in or out. Similar means may be provided for moving each of the disks l2.
In Figs. 3 and 4 is disclosed another embodimerit of the present invention. In this construction, the differentially movable elements are in the form of slides 28 having blank portions and open portions 29. These open portions 29 may be slots, recesses, or apertures of any desired shape, and the open portion of each slide is disposed on its blank portion at a different point along its length from the openings in the other slides. The slides 28 are disposed with their blank faces contacting and are adapted to have a differential sliding movement upon one another to bring their respective openings into registry with one. another, with the source of light and with the light sensitive element. This sliding movement is brought about by means of a key 3!! which may be inserted in a. key hole, not shown,
. trio cell circuit is closed and the relay and brought into contact with the slides, as illustrated in Fig. in opening. iii are in alignment, and the gized. slides 28 are held normal. apertures out of alignment by means spring pressed plungers, one of which is shown at i i. This plunger is confined between end of the slide and an element 32 of the casing iii. A plunger provided for each slide.
operation of this embodiment is clear. The is inserted through the keyhole and into engagement with the ends of the slides The key is so formed that inward movement thereof will displace the slides against their spring pressed plungers a distance sufficient to bring the various openings in registry so that light may pass from the source of light through the slides to the light sensitive element. The arrangement shown in Figs. 3 and 4 has the some advantages as the preceding embodiments, but in case the control mechanism is operated with a key.
In Fig. 5 is illustrated another embodiment of the present invention. In this instance, a casing it rotatably carries a shaft 24 which extends therethrough and beyond each side there of. The inner end of the shaft is mounted in a tubular bearing 33 which is provided at its outer end with a flange 33 having a recess into which a collar 3% of the shaft 24' fits to prevent the shaft 24 from being pulled in or out. The outer end of the shaft 24' is provided with a combined knob and dial 26' by which the shaft is turned the proper amount. Loosely mounted upon the bearing 33 are a plurality of disks if having openings 2i. Disposed between each two adjacent disks and keyed to the bearing is a. spring washer 35 which, due to friction, prevents the accidental rotation of the disks. The first three disks on the right of Fig. 5 are each provided with two driving pins 36 one extending from each face of each of these three disks. Thelast disk has only one driving pin 31 extending therefrom toward its adjacent disk. A dog 38 is rigidly secured to the inner end of the shaft 24' in any suitable manner and is adapted to rotate therewith. A nut 39 is threaded upon the inner end of the bearing 33 to hold the disks and washers in place on the bearing and the bearing 33 may be secured to the rear face of the casing it by screws or other suitable fastening means not shown.
In order to bring the openings ii of the disks I2 into proper alignment, the combined knob and dial 26, together with the shaft 24' and dog 38, is rotated in one direction until the dog 38 engages the adjacent driving pin 36 on the first disk. Upon further rotation of the shaft in the same direction, the first disk will be rotated and its other pin 36 will engage the adjacent pin on the second disk to rotate the same. Continued rotation of the shaft, until the dial has been rotated a predetermined amount, will cause the successive engagement of the remaining pins on the succeeding disks thereby causing the rotation of all of the disks until the outermost disk is in operative position. The shaft is now rotated in an opposite direction until the next disk is brought to operative position, when the direction of rotation of the shaft is again reversed until the next disk is brought to operative position. This rotation of the shaft in opposite directions is continued until all of the apertures in the disks are brought on a line with the light sensitive element l I and the: rays from the source of light it. The pins 36 and 31' are so angularly disposed in relation to their respective openings that proper movement of the knob and dial will align the openings in the disks. When the open ings are in alignment, the rays of light from the bulb lb will pass to the photo-electric cell it'- by means of a lens 22 and a reflector 40. The po sition of the pins tit and ill on the disks may be changed to vary the combination of the device.
As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense. 7
