Title: Improvements in or relating to the manufacture of lenses
IPC: C03B23/22
Filed: 1948-01-22
Abstract: 662,731. Moulding lenses. ABBEY, A. (American Optical Co.). Jan. 22, 1948, No. 2008/48. Class 56 [Also in Groups V and XXX] An apparatus for moulding lens blanks from heated plastic material such as glass, has two rotatable discs 5, 6, having a plurality of moulding, elements 15. 16 mounted thereon so that on rotation of the dies by interengaging;members 9 and 10, the moulding elements are brought together progressively in pairs in mating relationship to mould the lens medium introduced between them by automatic feeding means. In moulding countersunk lens blank, the moulding elements 15, 16 are seated in cavities 11, 12 in the dies 6, 5 respectively. The element 15 accommodates frictionally in a recess 19 a minor moulding metal element 20 having a convex surface adapted to form the countersink in the lens medium 4 being moulded. The medium 4 flows under gravity from an electrically heated hopper through a nozzle 3 which may be heated by a torch flame 92 and is cut off in suitable portions by a pivoted electrically heated knife 43. The spaced recesses 12, 11 have severing edges 13, 14. The element 15 may be provided with a bore 22 through which a tool may be inserted to eject the minor element. The temperature of the elements is controlled by impinging cooling jets of air or liquid from nozzles 75. Heated pre-formed segments 26 of glass, of a higher index of refraction than the lens medium 4, may be placed in the recess 19 instead of the element 20, to fuse in the lens to produce a multi-focal lens. The moulding elements may be formed of high melting glass or of metal alloys embodying nickel and tin, or of high chrome silicon iron, or of speculum metal. The minor moulding elements may alternatively be positioned in recesses provided in the element 16. The knife 43 is actuated in relation to the dies by cam means 55, the cam having a riser which causes the knife to dwell over the nozzle 3 after a cut and prevent the feed of further plastic material. After the period of dwell the knife is returned by the action of a spring on the plunger to permit a further flow of lens medium. The cam 55 also actuates a gravity feed mechanism. Figs. VIII and IX (not shown), whereby preformed segments 26 sliding under gravity down a heated slide 79 from a heated hopper 76, are allowed to drop singly into place on the rotating elements 15. After the moulding operation the lens blanks are fed on to a conveyer belt 68 to a receptacle 74. Modifications show a system of gears for constantly rotating the dies and describe means whereby preformed heated lens blanks with or without countersinks may be supported on the die 5, to be fused with preformed heated segments supported on the die 6, the blanks and segments being fed to the dies by a hopper.

Title: Improvements in or relating to clutches particularly for use in start-stop telegraphic apparatus
IPC: F16D41/02
Filed: 1952-02-01
Abstract: 695,088. Clutches. TELETYPE CORPORATION. Feb. 1, 1952 [Feb. 3, 1951], No. 2738/52. Class 80 (ii). A clutch comprises a plurality of abutting rollers disposed in an arcuate train between an inner peripheral surface on a driving member and a coaxial inner member the rollers being held out of engagement with the driving member in the inoperative position and being forced together to displace at least one of the rollers out of the train to engage the driving member in the operative position. As shown in Fig. 1, a series of rollers 20 are disposed between the inner periphery 17 of a driving member and the outer periphery of a disc 13 rotatably carried by a driven shaft 14. A stop 21, carried by disc 15 secured to the shaft 14, abuts one end of the roller train and a stop 18, carried by an operating member 16 rotatably mounted on the shaft 14, abuts the other end of the train. A spring 25 attached at its ends 26, 27 to the members 15, 16 respectively tends to urge the stops 18, 21 together but is restrained by a stop 28 engaging the member 16 and a detent 29 engaging, a lug 30 on the member .15. A garter spring 23 normally maintains the rollers 12 against the disc 13. To operate the clutch an electro-magnet 31 is de-energised to allow a spring 33 to raise the stop 28 out of the path of the member 16 which is then moved by the spring 25 to force one or more of the rollers 12 into engagement with the inner periphery 17. This periphery has notches 12 to give a positive clutching action but it may be made smoothly cylindrical in which case the clutch acts by friction. To disengage the clutch the magnet 31 is energised and moves the stop 28 into the path of the rotating operating member 16. The momentum of the driven member carries the lug 30 past the detent 29 and the clutch is held in the disengaged position shown. In a further embodiment, not shown, the operating member comprises lever means whereby a greatly increased force is applied to the roller train.

[Class 106 (i)] [Also in Group XV] Counting-apparatus, particularly for games such as darts, comprises. a number of dials 28 mounted on parallel spindles 26 each of which carries a ten-toothed wheel 29, 30, restricted to rotate in one direction only (e.g. by means of a pawl and ratchet), transfer from a lower to a higher wheel being effected by a spring- loaded finger 31 which is shaped for displacement against its spring so as to allow the higher wheel to be turned independently without affecting the lower wheel. The finger 31 has a cam surface 32 whereby it is forced out of the path of the wheel 29 when the latter is rotated directly by the knob 23. Idle wheels may be interposed between each pair of wheels 29, 30, so that all the dials will rotate in the same direction. An auxiliary dial 45 may be associated with each main dial 36 to indicate the last score made. Gear wheels 38, 43, driving this auxiliary dial may be disengaged by depressing a button 49 against the action of a spring 46 which also serves to return the dial 45 to zero. A similar disengagement takes place when the main knob 42 is rotated through more than a complete turn, a stop, 47 engaging a cam-shaped fixed stop 48 to force the gear wheel 43 downwards. A one-way coupling 40 prevents any transfer movement given to the toothed wheel A from being transmitted to the auxiliary dial.
