Title: Improvements in and relating to cutting mechanism for cigarette-making and like machines
IPC: A24C5/28
Filed: 1937-10-25
Abstract: 504,717. Cigarette-making machines. HORGAN, G. D., and INDUSTRIAL MACHINERY CO., Ltd. Oct. 25, 1937, No. 29062. [Class 130] In a rotary-knife cutting mechanism suitable for continuous-rod and like machines, in which the knife during the cutting operation moves axially with the cigarette rod, the knife shaft 5 is provided with an inclined cam plate 7 operating between relatively fixed abutment means adapted to oscillate about an axis which lies within the area of the cam plate, and preferably also about an intersecting axis at right-angles to the other. As shown, the shaft 5 is recessed at its end to receive the end of a driving shaft 13 carrying one or more pins 14 engaging in aper- 'tures in a flange 15 of the shaft 5. Each side of the cam plate 7 engages a pair of rolls 16 formed as ball races rotatable on spindle 17 on a mounting 18 supported to pivot about an axis parallel to that of the spindles. The support for the mounting 18 is a yoke 19 the arms 20 of which are pivoted on a framework 21 so that the yoke may oscillate about an axis at rightangles to the axes of the spindles and coinciding with the medial plane of the cam plate. The framework 21 is adjustable about a pivot 21a by means of a screw and nut device 22, 23 for adjusting the amplitude of reciprocation of the knife shaft. The ledger plate 29 is reciprocated by means of a forked member 31 engaging a collar 30 on the flange 15 of the knife shaft. Specification 476,618 is referred to.

Title: Improvements in carburettors for internal combustion engines
IPC: F02M3/14
Filed: 1920-10-14
Abstract: 171,027. Dodson, E. Oct. 14, 1920. Spray carburettors. -In carburettors of the kind having a slowrunning port which is cut off by the throttle valve or by the stem thereof when the throttle is opened, the leakage of rich mixture between the throttle and its housing is prevented by providing the throttle or stem with a groove or the like adapted to put the slowrunning device into communication with the atmosphere when it is cut off from the induction pipe. As shown, the rotary throttle valve A is provided with a groove A<3> which, as the throttle is opened, puts the slow-running port C into communication with an atmospheric port B. In modifications, the groove A<3> is provided in the side of a sliding piston valve, in the stem of a butterfly throttle valve, or in the end of a barrel throttle valve.

Abstract: 473,165. Making glass plates. VOSCH, J. M. J. C. Oct. 27, 1936, No. 29189. Convention date, Nov. 5, 1935. [Class 56] [Also in Group X] Corrugated sheets of glass for roofing or other purposes are formed with opposed recesses in their two surfaces so that the film of glass between them may easily be broken through to give passage to the screws or other fixing means. As shown the sheet-like stream of glass passing from the furnace between corrugating plates 1, 2 and rollers 3, 4 is partly pierced by punches 5 mounted on the rollers so as to become radially aligned at the nip. The punches may be removably mounted to vary the shape &c. of the recesses. According to the Specification as open to inspection under Sect. 91 the sheet stream after leaving the rollers is received between similarly corrugated metal plates arranged in a stack. At intervals the stack is moved downwardly to shear a sheet at 8, and the bottom sheet of glass with its supporting metal plate is conveyed away by rollers. A metal reinforcement may be introduced into the glass sheet before its exit from the furnace, the metal strip being fed downwardly through corrugating rollers. This subject-matter does not appear in the Specification as accepted.

Filed: 1941-02-28
Abstract: 572,532. Automatic guns. DOBREMYSL, J. Feb. 28,1941, No. 29440/39. [Class 92 (ii)] Relates to cartridge belt feeding devices, as described in Specification 572,534, which are mounted on a stationary part of the gun mounting and do not participate in the recoil movements of the gun as a whole. According to the present invention, the feed mechanism derives its movement from a movable member of the breech action within the gun itself, and the belt carrying and guiding means are mounted in a fixed position independently of the recoil movements of the gun. In the form shown, an arm 3 is fast with a rocking-lever 2 actuated by cam surfaces on the breech block, as described in Specification 572,533. The arm 3 is connected to a member 4 sliding longitudinally in guides on the outside of the gun casing and conveving transverse movement to the belt feed slide 14 of the feed-box 6 by a pin 5 engaging a cam slot 18. The feed-box 6 is connected by pillars 20 with a fixed base member 19 on which the gun casing 1 can slide. The arm 3 and member 4 can readily be dismounted and assembled on the other side of the gun when changing from leftto righthand feed. Specification 515,423 also is referred to.
