Title: Improvements in or relating to conveyor mechanisms particularly for use in labellingmachines
Inventor: SHERRINGTON JOHN EUSTACE
IPC: B65C9/02
Filed: 1954-03-11
Abstract: 779,341. Conveyers. PURDY MACHINERY CO., Ltd. March 7, 1955 [March 11, 1954], No. 7148/54. Class 78 (1). [Also in Group XXIV] A conveyer mechanism provided with a circulating support, e.g. the rotary conveying table 1 of the labelling machine described in Specification 779,342, [Group XVI], is driven, e.g., through gear-wheels 161, 162, from a shaft 163 which is rotated at a fluctuating speed from a shaft 165 driven at constant speed, by a sprocket chain 167 passed around sprocket 164 on shaft 163 and eccentrically mounted sprocket 166 on shaft 165. The varying amount of slack in the chain is taken up by sprockets 169, 170 freely mounted on bell-crank 168 which is biased to tension the chain by an anchored spring 171, the free end of which is connected by chain 173 around, and to a point on the periphery of, a sprocket 174 to which the crank 168 is secured.

Filed: 1972-02-16
Abstract: 1339364 Dry shavers T B TYLER 16 Feb 1972 [16 Feb 1971] 7230/72 Heading B4B A rotary dry shaver comprises a rotary cutting member 28 co-operable with a tiltable shear plate 21 retained in a housing 18 and is tiltably supported axially by a ring 23 independently of a spring 35 for biasing the cutting member into contact with the shear plate. The cutting member 28 includes upturned arms provided with two opposed cutting edges (29), Fig. 1 (not shown), and rotated, via a pin-and-slot connection 31, 32, by means of a shaft 30 rotated by a gear 34, the gear being driven by a reversible mains or battery energized electric motor 60, Fig. 11. The shear plate 21 is formed with a spherical-shaped wall which co-operates, as shown in Fig. 3, with the radiused edge of the ring 23, the cutting pressure being taken through each ring; the shear plate is prevented from rotating by means of lugs 25, Fig. 6. As shown, a pair of identical cutter assemblies are rotated by a common gear 63 on the motor shaft; in a modification, more than two assemblies may be driven by the motor. A plate 19 for retaining the shear plates in the housing is clipped therein by spring catch means 45, 46. Apertures 51 are provided in the wall of the housing 18 for the removal of hair clippings, the apertures being normally closed by spring-loaded side plates 52. A long hair trimming clipper, Figs. 11, 12, is driven by an eccentric 78 on the motor shaft, the pair of co-operable shear plates being both movable to an inoperative position by means of stud 77. The housing components and gears 34 may be of plastics material. In further modifications, the reversing of the drive may be effected through a gear system.

Abstract: 391,297. Glass manufacture. GASKELL, J., Stocks well, Hard Lane, St. Helens, Lancashire. March 12, 1932, No. 7425. [Class 56.] In apparatus for rolling wire glass, the support for a roll of wire netting, and a guide for directing the netting into the molten glass, are carried by a device which enables the supply of wire netting to be renewed quickly when a roll has been used up. The roll 1 of wire netting is supported by a frame 2 which is mounted on, and is free to turn stiffly about, an horizontal shaft 10. A tray 3 and a covering-plate 4, attached to the frame 2, form a mouth from which the netting 5 issues and is guided into the glass. The shaft 10 is carried by blocks 12 which are supported by a carriage 14 that runs on rails 16. The blocks 12 can be raised or lowered by screws 19 in order to adjust the frame 2 vertically, and the movement, in conjunction with the rotation of the frame about the shaft 10, allows the wire netting to be positioned correctly in relation to the sheet-forming rollers. When a roll of wire is exhausted, the carriage 14 is moved along the rails 16 and allows the frame 2 to be replaced by another, furnished with a new roll of wire, which is supported by a duplicate carriage that runs on rails 17.
