Title: Improvements in or relating to circular knitting machines
IPC: D04B15/60
Filed: 1936-04-20
Abstract: 474,030. Knitting-machines. BENTLEY ENGINEERING CO., Ltd., MANGER, C. F., WAINWRIGHT, C. H., and BUSWELL, G. A. April 20, 1936, No. 11303. [Class 74 (ii)] A circular machine having yarn - changing mechanism such as is described in Specifications 301,350, [Class 74 (ii)],and 408,598 and a splicing-yarn feeder to supply a yarn to a group only of needles, e.g., substantially one half of the needles, is provided with means whereby at the beginning of the knitting of the heel of a sock, the splicing thread is withdrawn as the heel yarn is introduced. Upon completion of the heel, the splicing yarn is introduced simultaneously with the change from heel yarn to foot yarn. The feeder 31 for the splicing yarn is moved by a spring 43 into feeding position, and is normally moved positively into non- feeding position by a lever 45 operated by a cam 69. When the splicing yarn is not required, a pattern-controlled stop lever 115 engages the lever 45 to prevent movement of the lever 45 by the cam 69. For operating the feeder 31 when the heel yarn is introduced, a cam 147 is provided upon the shaft 40 which carries the cams controlling the main-yarn changing. The cam 147 actuates an elbow lever 151, connected by a link 157 to the lever 45. The yarntrapping device 59 for the splicing yarn is actuated by cams 63, 65, 67, lever 71, and push rod 95. Stitch-slackening cams 121, 123 are provided so that longer loops can be drawn during splicing. Specifications 195,043, [Class 74 (ii)], and 414,039 also are referred to.

Title: Improvements in or relating to brake shoes
IPC: F16D65/08
Filed: 1945-05-05
Abstract: 583,509. Brake shoes. BENDIX AVIATION CORPORATION. May 5, 1945, No. 11460. Convention date, July 31, 1944. [Class 103 (i)] [Also in Group XXII] In brake shoes such as described in Specification 277,562, [Class 103 (i)], in which projections 14 on the shoe web are spread after insertion in apertures 20 formed in depressions in the arcuate rim of the shoe, the depressions completely surround the apertures and are spread in all directions by a punching operation as shown in Fig. 10. A suitable punch is shown having a sharply tapered end to provide a working edge for engaging the projections. If, in assembling, the web is moved parallel to the rim in the direction of the radius which passes through the mid-length of the rim and web, the slots on either side of this radius must be longer than the projections in order that the projections may slip into the slots. Because of this clearance the edges 36, 38 of an adjacent pair of projections are arranged closely to engage the corresponding edges of the slots to hold the rim against the braking torque. Both edges of one of the projections near the centre or one end of the web may instead be arranged closely to engage the edges of its slot.

Title: Improvements in or relating to splicing and like mechanism for knitting machines
IPC: D04B9/18
Filed: 1947-05-01
Abstract: 623,480. Knitting-machines. MELLOR, BROMLEY, & CO., Ltd., and SHORTLAND, A. May 1, 1947, No. 11719. [Class 74 (ii)] A splicing mechanism wherein the splicing thread is brought into contact with a main running yarn and carried by it frictionally to the needles, includes a splicing thread guilding element which withdraws the splicing thread from contact with the main yarn and directs it into a trapper. The mechanism, as applied to a rotary cylinder machine comprises a troughed member 3 carried by an arm 1, raised by pattern mechanism to carry the splicing thread T into contact with the main yarn Y. The splicing thread guiding element 17 is turned about a pivot 18 by a pin 20 on the arm 1 and the raising or lowering of the arm 1 causes corresponding movement of the element 17 to carry the yarn T towards or away from the yarn Y. The trapper comprises fixed and moving trapping elements 7, 8, the latter being carried on a spring-biassed spindle 9. The spindle 9 carries arms 22, 23 and has a member 13 notched to accommodate projecting cam surfaces 15 on a further fixed member 16. As the troughed member 13 is raised, a pin 24 on the arm 1 contacts the arm 22 turning the spindle 9, whereupon the member 13 rides over the cam surfaces 15 to separate the trapping members 7, 8 and release the yarn T. The lowering of the member 3 causes' a pin 25 on the member 17 to contact the arm 23 to close the trapper. The arm 1 may be operated through gears 26, 27. Members 16<SP>1</SP>, 7<SP>1</SP> on the trapper assist in guiding the threads.

Abstract: 616,709. Fuel-injection pumps. BLAKEWAY, R. S. April 18, 1946, No. 12079. Convention date, Nov. 7, 1945. [Class 102 (i)] [Also in Group XXVII] In a fuel-injection pump, wherein the plunger is actuated by the cylinder compression pressure acting on a spring-pressed piston, means are provided to adjust the force of the spring on the piston and to regulate the amount of fuel injected. The plunger 61 is reciprocated by cylinder pressure acting through a pipe 14 on a piston 28 loaded by a spring 50 adjustable by raising or lowering an abutment plate 49 by means of a cylindrical rack 44 rotated by a worm 46, a second rack and pinion 72, 69 coacting with a hexagonal port 62 of the plunger to rotate it, adjusting the slant cut-off edge 67 controlling the pump delivery. The compression pressure in the pipe 14, controlled by a valve 15 which may be connected to a governor, acts first on a valve 29 carried by the piston 28 and then on the whole piston head, fuel delivery through a port 56 and conduit 57 to an injection nozzle 83 starting when the edge 67 cuts-off the fuel inlet port 54 and ceasing when a groove 65 connects the pressure release port 58 to the inlet port 54. When the plunger passes the outlet port 56 the remaining fuel escapes to the groove 65 through a conduit 68 which is sealed by a conical cushion valve 60 at the end of the stroke. The injection nozzle 83 has an adjustably spring loaded needle valve 85 and a vent conduit 80.
