ELECTRICALLY OPERATED DRAWER Filed April 30, 1928 3 Sheets-Sheet 3 WITNESSES MENTOR #1 1:60am J K mer ATTORNEY Patented Aug. 26, 1930 PATENT @FFHCE FRANK J. KRAMER, OF GREAT BEND, KANSAS ELECTRICALLY OPERATED DRAWER Application filed April 30, 1928. Serial No. 274,105.

This invention relates to an electrically operated drawer for use in banks or financial in stitutions of any kind, and has for an object to provide a construction wherein substantially an ordinary drawer is presented and as sociated with means for locking the drawer both in an open and closed position with connections for actuating the locking means so as to move the same to an unlocked position.

Another object of the invention is to provide a drawer adapted to be closed by a spring or other means, and also to provide locking means capable of being moved by electro-magnets to open positions, the elecli tro-magnets being actuated from a distant point.

A further object, more specifically, is to provide a drawer wherein a switch is arranged at the bottom of the drawer normally held open by some of the money or other papers in thedrawer, the switch being associated with an alarm mechanism whereby when all the papers have been withdrawn from the drawer the switch will close the circuit of the alarm mechanism.

In the accompanying drawings,"

Figure 1 is a longitudinal vertical sectional view through a drawer and associated parts disclosing an embodiment of the invention;

Figure 2 is a bottom plan view of the drawer operating mechanism shown in Figure 1, part of the drawer being shown in connection therewith;

Figure 3 is a transverse sectional view as through Figure 1 approximately on the line Figure 4 is a fragmentary top plan view of the front part of the drawer shown in Figure 1, the same illustrating the switch embodying certain features of the invention;

Figure 5 is a diagram of the wiring for the magnet and associated parts shown in F igures 1 to 8.

Referring to the accompanying drawings by numerals, 1 indicates a casing or cabinet of any kind, and 2 a drawer. This drawer may be of any desired kind operated by a suitable pull 3. The cabinet or casing 1 may be of any desired type so as to support the drawer in proper manner. The supporting means for the drawer includes a rear supporting bar 4 and a front supporting bar 5. Brackets 6 and 7 are secured in any desired manner to the supporting bars 4 and 5, said brackets having apertures for accommodating the sliding rod 8. This rod is provided with an adjustable stop 9 for confining the spring 10 which surrounds the rod at one point and bears against abutment 9 and against bracket 7 for resiliently and normally holding the rod 8 in the position shown in Figure 1 with the adjustable stop 11 pressing against bracket 6. An adjustable stop 12 is also secured to the rod 8 and spaced a short distance from stop 11. When the drawer 2 has been pulled to an open position in the usual manner, the guiding bracket 13 carried by the carriage 14 will move along the rod 8 and engage stop 9. When the drawer 2 is fully opened, bracket 13 will move stop 9 against the action of spring 10 until the hook 15 moves over and interlocks with the stop 16 whereby carriage 14 and associated parts are held at a point near the front of the cabinet. This movement of the stop 9 and rod 8 causes the front face of stop 12 to be nearer the front of the cabinet than the hook 17 whereby drawer 2 may be closed but not locked in a closed position as the stop 12 engages the guiding bracket 18 carried by the drawer 2. The bracket 18 is provided with a base 19 rigidly secured to the bottom of drawer 2, and said base is provided with an integral extension 20 having an aperture for accommodating rod 8 and an abutment portion 21 against which the resilient bumper 22 strikes when the catch 23 including hook 15 is released. The carriage 1.4 may be built up of many pieces or formed of one solid piece, but must be provided with openings or passageways for receiving guiding bars 24 and 25 and with a plate 26 for carrying the bumper 22. The bracket 13 and also the abutment or catch bracket 16 are secured to the carriage 14 by screws or other means. Near the front of the cabinet is arranged a bracket 27 on which is pivotally mounted the catch 23, which catch is held in a given position by the spring 28. An armature 29 is connected to the catch 23 by a suitable arm 30, and this arm normally rests on the pin 31. A substantially ii -shaped frame 32 secured in any desired n anner to the respective supporting sections 323 and Ill of members l and 5. All these members. via. members 5, and may be of one piece of material or separate pieces connected togeth r to provide a support on which drawer may slide. In any event an opening 35 must be provided through which the bracket 18 and other parts may extend. The frame 32 supports in any desired manner a pair electro-lnagnets 36 which, when energized, attracts armature 29 and therefore swings catch 23 against the action (it spring 28 for releasii'ig hook 15 in case the same is interlocked with the lug or abutment 1(5. Adjacent the rear of the cabine' there is provided a catch 37 having a hook 1?. said *atch being pivotally mounted at 38 on a suitable bracket 39 and urged in a given position by a spri in armature l1 is rigidly secured to the catch 3? near hook 1?. said armature being adapted to be attracted by the electro-magnet l2 when said magnethas been energized. This iciently strong to overcome the LiUll of spring l0. so that when this magnet energized hook 1? is pulled away from the c t or abutment 1. thus releasing the drawer whereby it may be pulled manually to an open position. In usual ope ztion of the drawer, the same is pulled open to such an extent as to arise the lug or abutment 1(5 interlock with hook 15.

After this has been done the drawer may be closed, but it will not be locked closed as the ad ustable stop 12 will prevent the bracket from moving s l'licien rearw: rdly to interlock with hook 17. At any time the n agnets may be energized and when this occurs hook 15 will be moved to an unlock d position wherel'iy stop or abutment is w ll be disengaged and carriage 1st released. iis occurs regardless of whether the drawer is pen completely, partially open or closed.

This movement is icieut to cause the bracket 18 to g.-a =s hook 1?. whereupon this hook will interlock with b ket- 18 and thereby the drawer will become locked. As soon as the carriage it has been released from hook 15 bracket 13 will natural move away from the stop 9. whereupon ng will move rod 8 toboth sets of the magnetic members 36 and are ope ated from a distance. particularly in banks and other inaneial institutions. thus pmmitting someone at a d'-ance to she the d'awer and e se oi" highwaymen atthe teller.

As the current flows in this circuit the magnets 36 release catch 23 at the same time as hell 47 rings whereby springs 43 will quickly close the drawer. When an authorized person desires to remove all the contents from drawer 2 he merely swings the blade 49 to one side as illustrated in Figure 5, thus opening the circuit.
