SAFE-DOOR TRAP.

Specification of Reissued Letters Patent. Reigsued A13 13 1920.

Original No. 1,321,409, dated November 11, 1919, Serial No. 303,967, filed June 13, 1919. Application for reissue filed December 18,

To all whom it may concern:

Be it known that I, AJNA K. VVINTER, a citizen of the United States, and resident of New York city, in the county and State of New York, have invented certain new and useful Improvements in SaieDoor Traps, oi which the following is a specification.

The object of the present invention is to provide a trap in connection with a spindle lock, such as used on safe doors in which concealed arms or jaws will be released by the turning of the spindle by a person who does not know the proper operation, whereby the jaws will close on the hand or arm 01 such person, and remain locked in such position until released.

A further object of the invention is to provide an arrangement of this character in which the jaws can be released only from the inner side of the door or member, that is accessible only by some one who knows the combination opening the door.

In the accompanying drawings showing one embodiment of my invention, Figure 1 is a front elevation of the device.

Fig. 2 is a cross section on the line 22 of Big L Fig. 3 is a rear elevation.

i is a vertical section on line 4+4: of Fig. 3

Fig. 5 shows the trap members.

Fig. 6 shows the inner disk.

This invention comprises essentially a lock, especially of the spindle type, a pair of jaws normally concealed in the member to be brought together adjacent the spindle, and means whereby the operation of the spindle or lock, except in a certain peculiar manner, will result in the jaws being brought together.

As shown in the drawings, a member 2, that may represent a safe door, is provided with a lock in the form of a spindle 3 controlled by a handle 4, and which rotates in the door. An indicating dial 2 is located in front of said member 2 surrounding the sleeve on the diskQ-Q and is connected to said disk by pin 29. It is to be understood that this spindle will operate a combination lock in any well known manner. A pair of jaw members 5 and 6 are hinged together at 7 and 8 to surround the spindle, and are normally concealed in channels 9 and 10 in the door or member. The jaw members are 1919. Serial No. 345,919.

shown provided with bow portions 11 and 12 that serve to surround the wrist or arm of the person to be caught, by engagement of their inner ends 13 and 14, see Fig. 3. The jaw 5 has an extension or arm 15 projecting through the door, and engaged by a coil spring 16 that will serve to swing this arm from the concealed position toward the axis of the spindle 3. The other jaw 6 has a similar arm 17 engaged by a coil spring 18 to swing it toward the axis of the spindle; whereby the jaws are brought from the concealed position to engage the wrist of a person attempting to turn the spindle. ,Means are provided for locking the jaws in this closed position, shown in the form of a spring pawl 19 carried by the arm 15, that rides over a fixed segment 20 in the door, and prevents reverse movement or" the jaw when closed. A similar spring pawl 21 on the other arm 17 engages a fixed segment 22 on the door; whereby the aws wil] be locked in their closed position and firmly grasp the wrist or arm of the operator. It will be observed that the pawls are located on the inner side of the door, and when the door is closed are not accessible to release the person caught, until the door is opened, when each pawl can be lifted from its segment and the jaws released.

The jaws are normally retained in the open position by a trip device, that is released on turning the spindle, except upon special manipulation of the spindle. On the'inner side of the door is hinged a lever 23. arranged to engage the notched end 2% of the jaw arm 17, and retain the jaw in the open position until the lever is shifted. A similarlever 25 engages the arm 15 to hold the jaw 5 in the concealed open position. The spindle 3 projects through the door and has a disk 26 secured preferably by brazing on its inner portion, that is provided with notches 27 and 28 at opposite portions. A second disk 29 turns free on the spindl 8, and has notches 30 and 31, that on turning this disk will register respectively with the notches :27 and 28. 1 he inner ends of the levers 23 and 25 are provided with lugs 32 and 33, that are caused, by coil springs 34 and 35. on the lovers, to be pressed into the registering notches of the two disks upon turning the spindle and disks to such a relative position. But in any other relative position of the disks, except when their notches register and are located directly opposite these lugs, the springs will press the lugs on the levers against the peripheries of the disks. This will retain the levers in the described positions in which they will serve to hold the respective jaw members in the open or concealed positions. Normally the spindle is set in this manner, so that when turned in either direction by the handle to bring the registering notches of the two disks opposite the lugs, the coil springs on the levers will swing the levers to release the jaws, and the coil springs on the jaws will at once close the jaws on the arm of the person turning the spindle. It will be understood that the two pawls will lock the jaws in this arresting position, and the jaws can only be released by swinging one or both of the pawls, when access is had to the inner side of the door. Means are provided for locking the loose disk 29 to the other disk 26 carried bythe spindle, and releasing them, at the will of the operator. A coil spring 36 between shoulder 40 on spindle 3 and a flange 41 on sleeve 42, serves to press the spindle outwardly and hold the disks together, and

cause a stud 37 on the disk 26 to enter recesses 38 or 39 in the disk 29. By pressing inwardly on the handle 4, the stud will release the inner disk and the disks may be turned relatively, so that this stud can be caused to enter either of these recesses. The latter are so arranged that when the stud is in the recess 38 the disks have their peripheral pairs of notches in register; and upon pressing inward on the spindle this relative position of the disk is changed and the stud can be brought to enter the recess 39, which will lock the disks together with their notches out of register.

A mark can be placed on the handle as at 40, and marks placed on the dial as at ll, to indicate the relative positions of the disks.

In the operation of the device the disks are positioned with their notches out of register with the lever lugs, that will hold thelevers in position to engage the jaws and retain them in the open and concealed position. The disks are manipulated by the spindle so that they are brought with their pair of notches registering, but not adjacent the lugs on the levers. This is the set position of the device, and any person not understanding the proper operation, on turning the spindle and handle for not more than a half turn, will bring the registering notches to engage the lugs on the levers that will spring into the notches and release the jaws, and the latter will at once close on the operator. The door being closed, the pawls will hold the jaws in the closed position and can not be released until the door is opened. But a person understanding the operation, will first push the spindle inwardly and then give it a turn to bring the marks to register,

and can readily ascertain that the stud on the edge of both disks, they can not enter either of the notches and hence the levers can not swing. It is only by bringing the pairs of notches to register that the'lugs will enter such notches and shift the levers. lVhen a person has been trapped by the jaws, the person knowing the combination will operate the spindle by pushing in on the handle and inner disk and turning it in the inward position through tiie proper combination, that will permit the door to be opened. Then the pawls can be pulled back to free the jaws and the person caught will be released.
