1,261,062. Detecting washers and the like. ROCKWELL MFG. CO. 28 March, 1969 [15 April, 1968], No. 16361/69. Heading G4V. A rejector for apertured slugs for a vending machine in which a power driven coin handling mechanism is normally latched against rotation: and in which a latch releasing trip lever is moved by passage of a coin from a coin insertion slot in the mechanism housing to a coin entry way in the mechanism, comprises a spring biased pivoted lever having a nose portion extending into the coin path between the insertion slot and the entryway, the lever also having a portion adapted to engage and lock the trip lever except when the nose portion is cammed aside by the passage of a solid centred coin. If a slug is inserted the nose portion engages the aperture and the lever returns to its original position to lock the trip lever, thereby preventing both passage of the slug and actuation of the mechanism. General arrangement.-As shown a parking meter, Fig. 1, comprises a coin pan 32 having a raised peripheral wall 19 provided with a coin entrance slot 18. The pan is closed by a circular plate 79 driven by a spring mechanism, the plate bearing on its side adjacent the pan three equispaced coin catch plates 83 having edge flanges 84 which extend towards the rear wall of the pain 32. The pan is spaced from a frame plate 22 and is aperbured at 41 to admit lugs 40, 45 of lever 38 situated between the pan and the plate 22 and pivoted to the latter at 21. Lever 38 is spring biased so as to cause lug 40 to engage one of the flanges 84 and thus prevent rotation of circular plate 79. The top end of lever 38 is extended at 39 to project beyond the periphery of the coin pan. An arm 36, also disposed between pan 32 and plate 22 is attached to a cam assembly behind plate 22 and termnates in a plate 42 overlynig slot 18 so as to be engaged by the edge of a coin being transported .by circular plate 79 Movement of arm 36 sets the meter timing mechanism. The coin entryway is defined between a plate 56 bearing transverse end pieces 67, 68 and the coin pan, the plate 56 being resiliently-secured to a thickened land 26. The land has a lip 29, the wall 27 of which -is tangential with the pan assembly and overlaps the edge of plate 22. A further lever (110) (Fig. 3, not shown) is pivoted to the rear side of plate 22 and terminates in a vane 108 which projects between the coin slot 17 of the housing and the end 42 of lever 36 so as to prevent actuation of the lever 36 by a tool inserted through the housing. The rejector lever 10, Fig. 5, comprises a camming nose 112, an abutment edge 114 and-a lip 115, and is mounted by screw 13 between the housing slot 17 and the coin entry way so as to pivot in a vertical plane perpendicular to Fig. 1. Spring 12 biases the lever so that nose 112 is in the coin path and the left hand edge of the lever abuts lip 29. In this position the-abutment 114 overlies extension 39 of lever 38 and the lip 115 obstructs movement of lever (110) and vane 108 by blocking a tab 116 attached to the end of lever (110). Operation.-On insertion of an apertured slug the camming nose 112 of the rejector lever is displaced but quickly returns through the aperture, thus locking the latching lever 38 against release of the coin drive plate 79 and preventing the raising of vane 108. The slug therefore fails to be accepted and does not actuate the mechanism. When a normal coin is inserted the rejector lever remains cammed by nose 112 thus moving the abutment 114 and lip 115 out of blocking engagement with end 39 and tab 116 until the coin has been accepted.
