Title: Improvements in or relating to coin operated mechanism
Inventor: CUDWORTH DENNIS HINCHLIFFE
IPC: G07F15/02
Filed: 1957-01-02
Abstract: 853,189. Prepayment meters. GLOVER & CO. Ltd., T. Oct. 11, 1957 [Jan. 2, 1957], No. 143/57. Class 27 A rotary coin mechanism for a prepayment gas or other meter has a single striker plate 8 which engages one quantity wheel 11 on the insertion of the smaller of two designated coins and engages both wheels 11 and 12 on the insertion of a larger designated coin. The plate 8 is pivoted outside coin pocket walls 7 on a pin 9 carried by a lever 10 pivoted at 13 and a coin platform 2 slidable within the coin pocket has a pin 6 engaging a cam slot 61 in the pocket wall and a pin 5 engaging cam slots 51 and 71 in the plate 8 and pocket wall respectively. Depression of the coin platform 2 by a shilling moves the pin 5 to the ends of the first parts of the slots 51, 71 and the plate 8 pivots about 9 into engagement with the quantity wheel 11; the pin 6 in the lower slot 61 still engages a face 17 on the lever 10 and prevents it from pivoting. Insertion of a half-crown moves the platform through the shilling position and then causes the plate 8 to be withdrawn from the shilling wheel; further movement of the platform causes the pin 5 to strike the lever 10 at 101 and pivot it so the plate pivot 9 moves towards the quantity wheels and causes the plate 8 to move both sideways and downwards to engage both quantity wheels; the pin 6 has cleared the face 17 to allow pivoting of the lever 10. Coins of diameters other than those of the designated coins give rise to no effective operation or move the plate 8 to a position not in engagement with the quantity wheels. To convert the mechanism to single coin operation, a screw 15 normally fitted in an ineffective position on the blade 8 can be fitted at 15<SP>1</SP> to prevent full travel of the platform 2 on insertion of a larger coin or, after the pin 5 has been moved down the slot 51, at 15<SP>11</SP> so that only the larger coin will be effective. Specification 853,190 is referred to.

Class 74 (2) A yarn lever carrying a guide for reinforcing thread, which is controlled during rotation in a plane perpendicular to the needle axes, can also be displaced perpendicularly to this plane against the action of resilient means and at the moment when the guide reaches a normal plating position from a thread introducing position, by means of a member' adapted to be exactly adjusted on the machine frame. A reinforcement thread guide 1, with a large flat nose, is carried on a lever 2 which can reciprocate along and pivot about a screw 3 in a plate 4, in turn pivotable about a screw 8 in a base 7 fixed on a vertical pin 9 integral with the machine. A spring 6 normally holds the lever 2 in contact with the plate 4 and springs F2, F4 hold the plate 4 and lever 2 in the position of Fig. 4 corresponding to the inactive position of the thread guide, the end. of the reinforcing thread being then held by a thread gripping shears 12. When the reinforcing thread is to be introduced, as when starting the heel or toe of ' a sock or the like, the lever 2 and plate 4 are first swung clockwise and counterclockwise respectively to the introducing position of the thread guide. and the shears 12 made to release the thread, by cams on a control drum. The drum is then rotated to bring into operation lower steps on the cams, allowing the lever 2 and plate 4 to be returned by their springs to a plating position, in which the thread guide rides on to an adjustable stud 10, to determine its working height. At the end of the period of reinforcement, a further rack of the drum brings the thread guide back to its inoperative position and operates the shears 12 to cut and hold the end of the thread.

Abstract: 779,915. Spigot projectors for missiles. BLACKER, L. V. S. Dec. 15, 1955 [Jan. 6, 1955], No. 436/55. Class 92. Relates to projectors of the type including a spigot which enters a hollow tail tube of a projectile and which, when the projectile is to be shot off, is urged forward by springs from a cocked position to which it is returned by recoil from a driving charge confined in the tail tube. According to the invention, the spigot 4 Figs. 2, 4 is urged forward by a plurality of springs or as shown, spring units 20, 22, 24, 26, 28, 30 located around the spigot guide 10 and extending between a rearward anchorage on the spigot and a forward anchorage on the spigot guide 10, the spring units each being detachable from the anchorage on the spigot, thus permitting the spigot to be moved into a rear cocked position with the spring units detached, each unit then being stressed and re-attachec in turn to its spigot anchorage A bolt 16 Fig. 3 connects a block 14 to the rear end of the spigot 4, spring washers 18 being interposed between the block 14 and spigot 4. Each spring unit comprises a compression spring 32 Figs. 2, 3 confined between a stop 34 at the front of a surrounding tube 36 and a stop 38 at the rear end of a rod 40 anchored to a part 12 to which the spigot guide 10 is secured. The rear end of the tube 36 has an eye which can engage a stud 44 projecting from the block 14. A handle 46 is provided on the tube 36. Thus with the rear ends of the tube 36 detached from studs 44, the block 14 is pulled rearwardly until the spigot is cocked and then the tubes 36 are pulled rearwards one at a time and re-attached to the studs 44. The spigot is retained in the cocked position by a seat 48 Fig. 2 engaging the front end 50 of the spigot. The seat is pivoted at 52 and urged into engaged position by a spring 54. Two triggers 56 Fig. 4 are mounted on a shaft 58 which also carries a lever 60 Fig. 2 acted on by a spring 62. A disconnector 64 is pivoted to the lever 60 and has a nose 66 which engages a step on the seat. When the triggers 56 are pressed forward, the disconnector 64 raises the seat out of engagement with the spigot which flies forward and disengages the disconnector from the seat. As soon as the spigot returns the seat will engage it and the disconnector is returned into engagement with the seat by a spring 68. The projectile 6a Fig. 5 is retained in position in a trough 2 by means of a clip 70 which engages a bead 72 on the rear end of the tail tube 6 of the projectile. On firing the clip is detached and falls through a window 76 at the bottom of the trough. The spring units for the spigot may be replaced by helical tension springs.
