A COIN-CONTROLLED LOCKING MECHANISM.

Specification of Letters Patent.

Patented Aug. 1, 1916.

Original application filed June 12, 1911, Serial No. 632,716. Divided and application filed August 21, 1912,

Serial No. 716,195.

To aZZ whom it may concern:

Be it known that I, F RANK J. Rowen, a citizen of the United States, residing at Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Coin-Controlled Locking Mechanisms, of which the following is a specification.

My present invention pertains to coin controlled devices, and the present application is a division of application Serial No. 716,195, filed August 21, 1912 which, in turn, is a division of application Serial No. 632,716, filed June 12, 1911.

The present invention pertains more especially to the casing and means for attaching the same, having for its object to provide means for locking the casing to the door so that it shall be inaccessible to a person without a key to the door of the casing.

In the accompanying drawings which form a part of this specification, Figures 1, 2 and 3, are front, rear, and plan elevations respectively of my device shown mounted in a door, showing adjacent parts of the latter broken away, Fig. 1 is a vertical section through the device. Fig. 5 is a similar section with the parts in adifferent position. Fig. 6 is a vertical section through the upper end of the device at'right angles to Fig. 41. Figs. 7 and 8, views taken on lines 13, 13, and 14, 14, respectively of Fig. 4.

Like characters of reference indicate like parts throughout the views.

The casing inclosing my device may be of any form best adapted to carrying the operative parts. In the form thereof herein shown it comprises a front wall 16, top and bottom walls, 18 and 19, and side walls 20 and 21. The front wall 16 is provided with a coin'slot 22 in an intermediate portion below a visual orifice or window 23 at one side, and a cylinder or other well known look upon the other side. In the lower portion of this wall is an opening 25 closed by a removable door 26 also provided with a lock 27.

Fixed to the face of the door 30, which is typical of any door leading to a small room or cabinet, is a plate 31 which constitutes the back wall of the casing, and which is fastened to the door by screws 32. The plate 31 has its upper portion cut away as at 341 to receive therein a vertically slidable plate 35 having an offset upper portion 37 Serial No. 836,003.

resting against guide pins 38. Upon the lower portion of the plate 35 is a stud 39, and upon the plate 31, stop pins 10 and 41.

The front wall 16 of the casing, together with its integral side walls, are removable from the back plate 31, and may be detached by one having access through the door 26 by virtue of the following connections: In the bottom wall is fixed a plate 43 whose upturned flange 14 is perforated to receive screws 46 which enter openings 47 in the back plate. The upper portion of the casing is connected by virtue of a plate 419, fixed to the top wall 18 by screws 50, and provided with a downturned lip 51 which engages the back face of the offset portion 37 of the slide 35,

Resting against the plate 31, as shown in Fig. 7, is a horizontally disposed bolt comprising a fiat shank 53, and a head 54; the former having its rear end provided with a longitudinal guide slot 55, an outturned finger or projection 56, and a downward finger 57 The forward portion of the body is also downwardly extended as at 58.

The bolt is guided by a pin 59 in the plate 31 extending through the slot 55, and the bolt head is movable into and out of a bolt receiver 60 fixed by screws61 or otherwise to the door jamb 62. The face of the bolt is provided with a horizontal track 6 1 terminating in a vertical contact edge 65. Passing through openings 66 and 67, in the door 30 and plate 31 respectively is a hollow shaft 68 provided with a handle or lever 69 on its outer end, and upon whose inner end is fixed a disk 70provided upon its upper edge with an elevated curved cam shoulder 71 contact ing with the stud 39, and having two clownwardly inclined projections 7 2 and 73. On the upper margin of this disk is a stud 7 5 upon which rests a pawl 7 6 pivoted at one end upon a pin 77 in the plate 31. The pawl has a concavity 78 in its upper edge and another 79 in its lower edge. The stud 40 is a stop to the travel of the disk in one direction, and a spring 81, provided with an in termediate coil 82, and fixed by solder or otherwise to a partition plate 83 in the casing presses with its free end against the arm 72 of the disk forcing the arm 73 against the stop screw 11, which is for operative purposes the limit of the travel of said disk in the direction of the arrow. Under certain conditions the screw 41 is removed,

in which case the pin 40 is the stopping agent. Under operating conditions the cam edge 71, through the pin 89, keeps the slide 85 elevated, thus locking the housing against the back plate. When, however, it is desired to remove the housing the door 26 is removed, and the operator, through the opening 25 unscrews and removes the member 41 whereupon the disk swings against the pin l0, and the pin 39 drops from its elevation permitting the slide 35 to fall and disengage the lip 51. The bottom portion of the casing is readily detached because the screws 46 are directly accessible through the opening 25.

What I claim is,

1. In a device of the character described, a closure member, a plate fixed thereto, a casing, a plate slidable with relation tothe first-named plate and adapted to engage a portion of said casing to secure the latter to the closure, a disk and means carrying the same, and means car ied by said slidable plate and bearing upon said disk.

2. In a device of the,character described, a closure member, a plate fixed thereto, a casing, a plate slidable with relation to the firstnamed plate and adapted to engage a portion of said casing to secure the latter to the closure, a disk and means carrying the same, means carried by said slidable plate and bearing upon said disk, and a key-controlled door for said casing.

3. In a device of the character described, a

closure member, a plate fixed thereto, a casing, a plate slidable with relation to the firstnamed plate and adapted to engage a por" tion of said casing to secure the latter to the closure, a disk and means carrying the same, means carried by said slidable plate and bearing upon said disk, a key-controlled door for said casing, and a removable me1nber operable through said door which, when removed, permits the disk to be moved out of the path of said pin.

4L. In a device of the character described, the combination with a closure member, of a plate fixed thereto, a casing, a slidable plate mounted upon the first-named plate and adapted to engage a portion of said casing to secure said casing to said closure, an inner handle, a disk mounted upon said inner handle within said casing, a pin carried by said slidable plate and bearing upon said disk, whereby said plate is held in an ele vated position, a key-controlled door for said casing and a removable member operable through said door which, when removed permits the disk to be moved out of the path of said pin and permits the slidable plate to descend to unlock the casing from the closure.

In testimony whereof I have ailixed my signature in presence of two witnesses.
