Abstract: 874,858. Toy fire arms. GLASS, M. I. July 27,.1959 [Aug. 1, 1958; May 8, 1959; May 11, 1959], No. 25746/59. Class 132(3). A toy gun comprises a firing mechanism for producing a noise simulating firing of the gun and also includes a mechanism which produces a ricochet-like sound and which is driven by a force created incident to movement of the trigger. A cap gun comprises a mechanism 33 for feeding caps upwardly against an anvil 31 provided with ports 129, 131. A hammer arm 27 pivoted at 49 is biased forwardly by a spring and has a tang 55 engageable by a tang 43 on the trigger 25. The ricochet sound producing mechanism 61 includes a vibratable membrane supported by the walls of the butt and engaged by a vibrator 67 which comprises a length of spring wire secured at 74 to the butt of the gun. The free end of the vibrator is engageable by releasing lever 79 pivotally mounted on an actuating lever 77 which is pivoted to the butt at 78 and connected to the hammer arm 27 by a slot and' pin connection 85. Means for delaying operation of the sound producing mechanism 61 until a time subsequent to the firing of the gun consists of a flywheel 99 supported in a pivoted sub-frame 81 and biased in a clockwise direction by a hairspring 103. A stop 105 limits the rotation of the flywheel which is also provided with an actuating pin 107 for engagement with a cam 89 on the actuating lever 77. The sub-frame 81 is normally prevented by a stop 119 from moving into a position where the pin 107 can engage the releasing lever 79 to operate the ricochet sound producing mechanism. The stop is carried by a hinged plate 121 forming one wall of a gas chamber 123 connected to the anvil ports 129, 131. In using the gun, rearward movement of the trigger positions a  cap 60 adjacent the anvil ports, cocks the  hammer arm, and causes the lever 77 to pivot to locate the cam 89 in position for striking the flywheel pin 107, Fig. 6. When the hammer arm is released, the cap is ex-  ploded and the lever 77 pivots rapidly clockwise to cause the cam 89 to strike the pin 107 and thus rotate the flywheel counterclockwise; the vibrator wire 67 is also tensioned. The gases produced by the cap  explosion cause the plate 121 to swing out-  wardly and the stop 119 to be withdrawn from engagement with the sub-frame 81 which pivots further counterclockwise. The  flywheel pin 107 is thus able to pass to the  rear and clear of the cam 89 after the flywheel. has rotated approximately three  quarters of a revolution and reversed its direction of rotation under the action of.the hair spring 103, Fig. 8. The pin then strikes: the upper edge of the end 95 of the releasing lever 79 and the vibrator 67 is released to produce the ricochet sound effect. In the  event that the gun does not fire when the. hammer arm is released, the stop 119 is not disengaged from the sub-frame 81 and the pin 107 is prevented from releasing the vibrator. In a further construction, Figs. 12-22 (not shown), a vibratable membrane for the: sound producer is secured between concentric metallic rings of which the outer ring! has a pair of ears for fastening to a frame member of the gun. Operation of the sound producer occurs upon forward movement of; the trigger and the time delay feature is thus controllable by the user of the gun. Toy fire arms including rifles and shotguns are specified.
