SAFE HAVING COIN-GPERATED LOCK.

evince.

To all whom 'it may concern:

Be it known that I, MAX EMER, a subject of the Austro-Hungarian Emperor, and residing at 35 Klostergasse, `Vienna` XVHL in the Empire of Austria-Hungary, have invented certain new and useful Improvements in Safes Having Coin-@perated Locks, of which the following is a specification.

This invention has for its object to provide an improved safe for keeping valuables in public institutions or the like, of the kind in which the safe can be locked only after insertion of a coin and the key cannot be removed from the keyhole, once the safe is opened.

rFhe present improvements consist more particularly in the feature that the inserted. coin is pressed by means of a part, suoli as a lever or the like, against a member which is supported in the open position of the lock bolt, partly by the lock bolt and partly by the wall of the safe, whereby the said member is moved out of the position in which it prevents the lock bolt from being shot, and by this movement permits of the safe being locked, the coin being thrown off by the movement of the bolt in the usual way. The said member may consist of one part or of several parts pivoted or hinged together. ln the first case the member may either' be pushed by the coin out of the line of support parallel to itself, or it may be hinged to the lock bolt or to the wall of the safe, so that the member is rocked on the axis of the hinge by the coin out of the supporting line of suppo-rt. ln the second case it is preferred to connect the member to the bolt as well as -to the wall of the safe by means of hinges, the parts of the member being rocked out of the line of support on the two hinges and on the central connecting hinges.

In the drawings Figure 1 is a sectional elevation of one modification of the improved safe. Fig. 2 is a cross section on the line AA of Fig. 1; Fig. 3 is a longitudinal section on the line B-B of Fig. 1g and Fig. /1 is a cross section on the line C-C of Fig. 1; Fig. 5 is a section of the mechanism for stopping the lock bolt, shown in its inoperative position, Fig. 6 is a section of a modified construction of the mechanism for stopping the lock bolt, in one position, and Fig. 7 is the same section of the said mechanism showing the latter in a different position, and Fig. 8 is a section of a Specification of Letters Patent.

further modification of the mechanism for stopping the lock bolt.

rlhe safe consists of a back plate 1, which is adapted to be fastened to a wall or the like, and of a casing 3 adapted to rotate on a hinge-pin 2. The back platel may however be connected to the sides to form the casing, and only the cover of the safe may be hinged. A compartment for receiving the automatic coin-receiving apparatus is formed in the casing 3 by means of a tran-sverse partition 1- and a back wall 5, the case of the locking mechanism being formed by means of a longitudinal partition 6 and a back wall 7. The transverse partition 1 stops short of the bottom of the safe, so as to leave an aperture for the insertion of a money box into the compartment. rFWO catches 8 are pivoted on the back plate 1, and are adapted to engage by holes therein over knobs 9 on the casing 3, for the purpose of keeping the unlocked safe closed;

1() is a slot in the back wall 5 for the insertion of a coin, leading into a coin chute formed by two vertical partitions 11 and the horizontal arm 12 of a bell crank lever 12. rllhe free end of the other arm 122 of the lever 12 is provided with a pin 13 projecting through an aperture in the wall 5, which comes in contact with the back plate 1 when the safe is closed and is thereby pushed inward, so that the lever 12 is turned against the action of a spring 14C and the lever arm 12 is raised. lf desired, the coin slot 10 may be located in the front wall of the casing 3 and the pin 13 of the lever 12 may be arranged to project through an opening in the top of the safe. ln such a case the lever will have to be actuated by pressure applied to the pin 13 by the finger of the user. When shot, the lock bolt 15 engages by means of its hooks 15 in the apertures of the lug 16 fixed to the back plate 1; it is constructed in a well known manner, such that when the lock is open the key 17 cannot be removed from the keyhole. The bolt 15 is provided with a lateral arm 18 which, in the construction shown in Fig. 3, consists of two parts 18 and 182, whereas in the construction shown in Figs. 6 and 8 it is formed in one piece. rllhe two parts 18 and 182 (Figs. 1 and 3) are so combined thatat the commencement of the movement of the lock bolt only the part 18 attached to same will move with it, while the other part 182 will be moved only by the further movement of the lock bolt. F or this purpose the part 18 is formed with a slot 183, in which a pin 18t ot part 182 is adapted to slide.

2O (Figs. 1, 3, 5) is a member consisting of two parts connected together by a hinge 19; it is hinged at 21 to the arm 18 of the bolt 15. The other end of the member 2O is connected to a projection 22 on the wall oie the sate by a hinge 23. The hinges 21 and 23 permit of the parts of the member being turned upward, while the hinge 19 opens toward the opposite side. The member 2G is held extended by a spring 21# and thus prevents the locking movement ot' the lock bolt.

25 is a forli-shaped projection on the underside ot the member 20, it is adapted to receive in its tori; the upper edge of the inserted coin 26.

lhen the sai-'e is closed after insertion of a coin 2G, the horizontal arm 12 of the bell crank lever 12 is raised owing to the pin 13 coming in contact with the bacl plate 1, and the coin 26 resting on it is pressed against the member 20, whereby the parts of the said member are swung upward out of the line of support drawn through the projection 22 and the end or" the bolt arm 18. 1n this movement the pin 18 shifts slightly in the slot 183. rEhis play between the two parts prevents the member 2O from swinging out too far. 1n this partially swung out position the member 20 does not offer any resistance to the movement of the locl bolt, and the safe can then be locked. By the locking movement the parts of the member are swung still farther outward and at the same time the coin 26 is brought into a slanting position (Fig. 5) by the forked projection 23, which moves simultaneously and thus causes the coin to fall. r1`he coin falls into a funnel 27, under the mouth of which is the coin slot 28, fitted on the inside with a spring flap 282 of a money boX 28, the hinged cover of which can be locked by means ot a lock 29.

rlhe money box 28 is placed in the compartment formed in the casing o1 the safe and is held therein by the bolt 30 of a loch 30 fitted on the money box or on the wall of the sate. rlhe money box 28 can be removed from the safe after unlocking` the locl 30, but its contents, however, are only accessible after the second lock 29 has been opened.

The construction of the money boX and the locking orp same in the safe, do not form any part of the invention. 1n drawing back the bolt lock the member 2O is returned by the spring 24 into the position in which it stops the loclr bolt.

1n the bolt stopping mechanism shown in Figs. 6 and 7, the member 2O is formed in one piece, is actuated by the spring 2% and is hinged at 21 on the bolt arm 18. 1n the unlocked position of the lock bolt the free end of the member 2O bears against a projection 22 on the wall of the safe. 0n raising the lever 12, the member 2O is raised by means of the inserted coin 26 sufficiently to allow of the free end of the member 2O coming above the projection 22, over which the said member slides during the locking movement of the lock bolt.

ln the construction shown in Fig. 8 the member 20 bears with a shoulder against a projection 31 on the transverse partition 4, over which the shoulder of the member must be raised by the coin, in order to permit of the locking movement of the lock bolt. rl`he member stopping the movement of the lool; bolt may also be shifted by the coin parallel to itself to such an extent as to allow of the locking movement of the lock. The herein described bolt-stopping devices may also be used with vertical lool; bolts and the lever for pressing the coin against the stopping member may be arrangel to swing in an inclined plane, or even a horizontal plane. lnstead of allowing the lever to act directly on the coin, the said lever may also be coupled to a sliding part acting on the coin,

r the pressing of the coin against the stopping member may also be effected alone by a sliding piece.

Having now particularly described and ascertained the nature oit my said invention and in what manner the same is to be performed, 1 declare that what I claim is 1. A coin controlled lock, comprising in combination with a casing, a. lock bolt, means removably interposed between said lock bolt and the wall of said casing to obstruct the movement of said bolt, a coin chute having a. movable bottom, an element carried by said interposed means and forming the top of said coin chute, and means to actuate said movable bottom against the inserted coin to move said interposed means out of the path of said lock bolt, whereby the latter may be thrown to locked position.

2. A coin controlled lock, comprising in combination with a casing, a sliding lock bolt therein, removable means interposed between said lock bolt and said casing to obstruct its sliding movement, a coin chute comprising tiXed sides and a movable bottom, means to actuate said bottom against a coin when the casing is closed, and means carried by said interposed means to be actuated by said coin when the latter is moved by said bottom, to remove said interposed means from the path of said sliding lock bolt, whereby the lock may be thrown to locked position.

3. A coin controlled lock, comprising in combination with a casing, a sliding bolt, means interposed between the end of said lock bolt and the wall of said casing to prevent the sliding movement of said bolt, said interposed means being constructed to be swung out of the path of said bolt, a coin chute located adjacent said interposed means, a movable bottom in said chute adapted to lift a coin, and a device opposing said movable bottom and carried by said interposed means, whereby when said movable bottom lifts a coin, the latter will bear against said opposing device and throw said interposed means out of the path of said sliding lock bolt.

t. A coin controlled lock, comprising in combination with a casing, a sliding lock bolt, a jointed element interposed in the path of said sliding lock bolt between the latter and the wall of said casing, means to receive a coin, a device to lift said coin and said receiving means, an elem-ent opposing said lifting device and carried by said interposed means, whereby when said coin is lifted it will bear against said opposing element and throw said interposed means out of the path of said lock bolt.

5. A coin controlled lock, comprising in combination with a casing, a sliding bolt, an element jointed to said lock bolt and bearing against the wall of said casing in the path of movement of said lock bolt, a coin chute located at one side of said interposed element, a device movable toward said interposed element through said coin chute, a device carried by said interposed element opposite said lirst mentioned device, and means to move the latter when the casing is closed whereby the latter is adapted to bear against the inserted coin to raise said opposite device to throw the interposed element out of the path of movement of said sliding lock bolt.

6. A coin cont-rolled lock, comprising in combination with a casing, a sliding lock bolt, an element hinged to said lock bolt and bearing against the wall of said casing, in the path of movement of said bolt, a coin chute located at one side of said interposed element, a rock arm forming the bottom of said chute and movable therethrough, a forked element carried by said interposed element opposite said rock arm, and means to move said rock arm toward said forked element, whereby, when a coin is inserted in said chute, said interposed element may be thrown out of the path of movement of said sliding lock bolt- 7. In a coin controlled lock, comprising in combination with a casing, a sliding bolt, a jointed element interposed between said sliding lock bolt and the wall of said casing in the path of movement of said bolt, a coin chute located at one side of said jointed element, a rock arm pivoted to form the bottom of said chute, and to be movable therein, a forked element carried by said jointed element above said chute and opposite said rock arm, and means to actuate said rock arm toward said forked element, when the casing is closed, whereby when a coin is inserted in said chute, between said rock arm and said fork element, the latter will throw said jointed element out of the path of movement of said sliding bolt.

ln testimony whereof l affix my signature in presence of two witnesses.
