Abstract: 1503146 Coin operated wire rope lock J W GREEN 2 May 1975 [13 May 1974] 21000/74 Heading G4V [Also in Division E2] A look apparatus including a key operable lock and a body provided with a cavity tangentially communicating with an elongate element receiving passage, a spring biased cam being rotatably mounted in the cavity and urged into a position in which the cam bears on an inserted elongate element to prevent its removal from the passage, the cam being rotatable by the lock to release the element. The lock apparatus is shown in combination with a coin control mechanism. A coin is inserted through sizing plate 2 and then bears against top plate 4 before passing along a channel to a recess 6<SP>1</SP> in a coin-carrier 6. Small coins pass behind recessed shoot plate 5 and through reject opening 8. Recess 6<SP>1</SP> as shown is adapted to accept two coins 9. The second coin bears on chamfer 11 and is raised with respect to the other coin. Adjustment to cater for different numbers of coins is possible by removal or replacement of dummy plate 10. The carrier is eccentrically mounted on spindle 15 of a lock 57 and is prevented from rotation by pawl 12. The raised coin allows the carrier to pivot into a horizontal position where the coins engage wall 14. Loosely coupled to spindle 15 is a cam 16 which is rotatably mounted in cavity 51 of body 52 by means of an annular flange. Body 52 holds the lock 57 and has a bore 19 communicating tangentially with cavity 51. A torsion spring 17 biases cam 16 to wedge cable 18. Release of cable 18 is achieved by means of a key to turn lock 57. Lock spindle 15 has a lug arranged to engage a lug on cam 16. Rotation of the spindle also moves carrier 6 back to its vertical position. In so doing the coins rotate over radii 20, 21 and pass into a lower channel. The coins may be passed back to the user or pass to a coin box. A ratchet device shown in Fig. 9 ensures that carrier 6 has to complete a full movement in either direction before a reversal of rotation is possible. The sizing plate, head plate and coin carrier can be replaceable to cater for differently sized coins.

Abstract: 1,210,989. Feeding sheets. HARRIS-INTERTYPE CORP. 23 April, 1969 [9 May, 1968], No. 21238/69. Heading B8R. Sheets are separated by conventional suckers from the top of a stack 10, Fig. 1, and fed to tapes 11 and below wheels 12 and guide rollers 14 to be fed in underlapping relationship over a register plate 15, Figs. 1 and 2, and against front stops 17, being thereafter laterally registered by conventional means 21. Retaining fingers 22 are then lowered to press the front sheet S against belts 27 on openings 28 in the plate 15, the belts having openings through which suction is applied through a valve 34 and recesses 33. The fingers 22 and the stops 17 are then raised and the belts driven forward at a speed greater than that of the tapes 11 to separate the sheet S from the following sheet S1 and move it against stops 24 on printing- press cylinder 16, on which it is held by conventional grippers 25. The stops 17 are then lowered, the fingers 22- lowered to an intermediate guiding position, the vacuum cut off and the belts driven backwards to their initial position, while compressed air is supplied to the recesses 33 to hold the sheet S1 clear of the belts until it abuts the stops 17. The belts are driven in both directions by drive pulleys 29, Figs. 2 and 4, to which the ends of the belts 27a, 27b are attached. The belts are driven forwardly in both directions by cams 52, 54 acting on rollers 50, 51 on a bell-crank L. At both extreme positions of the pulley 29, the recess 35 in which the ends of the belts are held remains below the points of tangency of the belts on the pulleys. The length of the belts round the pulley is greater than that of the sheet-engaging portion of the belts, and the diameter of the pulleys is also greater than said sheet-engaging portion. The tension of the belts is adjustable by inserting or removing shims 40. In another form the run of the belts between the pulley and either guide rollers 30 or 31 is bent inwards by a deflection roller, the shaft of which may support the fingers 17, or which may be spring-biased to maintain apredetermined belt tension. The deflection roller produces a greater wrap-around of the belts on the pulley, thus allowing a greater angular rotation and therefore a smaller pulley.
