This invention is aguard for entrance i' sl'ots'and isintended primarily for use in I connection with the coin. tubes of coincon trolledmachines but may without'substan- L tial structural changes be employed as a guard for keyholes"and other structures in which 1 an operating element'listo be inserted through an' entrance Opening to reach and actuate other parts," Owners of coin-controlledmamischievous or; evil disposed persons insert- I ingin the coin slots paper, chewing gunr or other material which choke'thecein slots and prevent the use of the machines until after the obstructions have-been removed. In many. instances, it is necessary'to dismantle I the machine in order to vremove the obstructions,o,thereby incurring considerable exp ense as well as losing the use oi the machine while the necessary repairs are being made. It is the objectof my inventionto provide a sim-. ple and inexpensive mechanism whichwill eflectually close the coin slot against the entrance of pa'per or other material whichis apt to choke the slot so .thatthe slot will always be in condition to admit aicoin, and a further object of the invention is to provide.

' acoin guard which upon the entranceof a (coin will operate'to propel the coin intojand through the coin tube Or -chute. One embodi- V ment of the inventionis illustrated in the acj 7 companying drawing and will be hereinafter] 7 fully described, the novel features being par- ,rticularly pointed out in the appended claims."

edge and the coin slot above the slot and thereby prevent the coin being inserted through the slot in such position that it will not enter Pivotally mounted at their rear ends in openings-14 provided therefor in the upper plate 5 are jaws 15 having rearwardly projecting shanks or stems 16 formed with down-turned tenons 17 engaged through the openings 14 so as to constitute pivots for the jaws. The inner opposed edges of the guards to prevent the entrance of paper or the like into the coin chute through the ends of the coin slot. The depending lips 18 terminate short of the inner edges of the respective jaws which are stepped, as shown at 19, and at the transverse side of each step 19 is a second depending lip 20 which is disposed at a greater distance from the coin slot than is' the respectively ajacent lip 18 and each lip 20 has its inner edge or end extended inward:

ly beyond the inner straight edge of the respective jawyas shown at 21, whereby to. meet on the medial line of the coin chute under the tongue 13 so'that when the parts are in normal position the guard will extend through the entire extent of the slot.

1 When a coin, indicated at 22, is inserted through the coin slot 4, the edge of the coin will impinge against the inner opposed edges of the lips 18 and by reason of its curvature will pass between the said lips so that the pressure exerted upon the coin to pass it through the coin slot will tend to spread the lips and open the jaws; Obviously, thisopening movement effected by engagement of the coin with the lips 18 :willbe comparatively slight but as the entrance of the coin continues its edge will engage the opposed ends of the lips 20 and will fullyopen the jaws so that the coin may pass into the coin chute. Thejaws are normally held in their closed position and caused to yieldably resist the entrance of the coin by a spring .23 which, in the form. shown, rests upon the upperplate 5 of the coin chute and has its ends passing under the' keeper 11 to bear against the outer sides of the stems 16 of the jaws. When the jaws are opened through the engagement .therewith of an inserted coin, the ends of the spring will be spread and the spring thereby put-under increased tension. As soon as that 7 diameter of the coin which is substantially parallel, with the plate 3 or the frame of the ment covering of the lips 20, the spring will contract and close the jawsand this action will cause the ends 21 of the lips 20 to ride upon the edge of the coin with such force that the coin will be forciblydriventhrough the coin chute and coin but will effectually resist the entrance of paper or gum or other material which is lack- 7 ing in rigidity and, consequently, such material cannot be passed through the coin slot into the" coin chute but will remain in the slot and it may be easily removed from thecoin slot without requiring a dismantling ofthe. entire apparatus. The device isvery simple way with the'usual arrangement and opera- 8 tion of the mechanism' of the coin-controlled machine. *f j V .Having thus described the inventiomll claim:. c i
