Title: A device for the localized production of a greater loop length in flat hosiery frames
IPC: D04B11/00
Filed: 1932-08-10
Abstract: 399,301. Knitting-machines. LIEBERKNECHT, P. and MASCHINENFABRIK EINSIEDEL GES., Einsiedel, near Chemnitz, Germany. Aug. 10, 1932, No. 22368. [Class 74 (ii).] In flat machines of the Cotton type employing fast and loose levers 4, 5 respectively and cams 10 for producing greater loop length at desired intervals, unnecessary movement of the loose levers, during inoperative periods, is prevented by springs 12 which hold them against guiding cams 11. In a modification, the fast and loose levers are mounted on a separate shaft and additional movement is imparted to the regulating shaft at appropriate times by a lever fast to this separate shaft. During inoperative periods the additional shaft and the levers carried thereby are prevented from participating in the movements of the regulating shaft by a spring which holds a lever, fast on the separate shaft, against an additional guiding cam.
Patent GB-224296-A (GB)
Abstract: 224,296. Marks, E. C. R., (Snappy Manufacturing Co. of Canada, Ltd.). Aug. 9, 1923. Animal traps.-A continuous-action trap in which the animal interfering with the bait releases a spring-actuated rotary striker is provided with means which slow down the striker as it approaches the resetting position so as to ensure that the parts re-engage correctly. The striker 14 is mounted on a shaft 12 between two springs 13, the inner and outer ends of which are attached to the shaft 12 and the striker respectively. At each end of the striker there is a blade 33 and a hook which engages on a shoulder 23 on the front face of a plate 21 attached to a depending arm 22 pivoted at 20 and held against rotation by a tongue 27. This tongue is formed on a plate 26 extending through a hole 28 in the arm 22 and attached to a trigger 24 pivoted at 25, so that the tongue 27 engages the lower edge of the hole 28. A spring 29 tends to press the trigger 24 in a counterclockwise direction and the bait is carried on a stirrup 30 which straddles the trigger 24 and is pivoted at 31. When the animal interferes with the bait the) member 30 is rocked and depresses the trigger 24 so that the tongue 27 is raised and releases the arm 22 which is thereupon rotated clockwise by the tendency of the springs 13, whereupon the striker is freed from the shoulder 23 and rotates sharply. After nearly half a revolution the other end of the striker 14 hits the cam face 21<a> of the plate 21 so as to rotate the arm 22 counterclockwise, slowing down the striker 14 and causing the shoulder 23 to engage the striker 14, and the tongue 27 re-engages the arm 22, to the lower end of which is attached a dash-pot piston to ensure that the force of the springs 13 does not cause the arm 22 to rotate so sharply as to rebound before engaged by the tongue 27.

Abstract: 407,721. Gear-cutting. WHEATLEY PATENTS, Ltd., 2, Norfolk Street, Strand, London, and GUEST, J. J., Furzedown, Knee Hill, Abbey Wood, Kent; and BARCLAY'S BANK, Ltd., 54, Lombard Street, London, WHEATLEY, L. D. B., Rhossilly, Glenfield Road, Banstead, Surrey, and ARNOLD, A., 64, Bennett Road, Richmond Park, Bournemouth, (Representatives of WHEATLEY, H. H.). Aug. 16, 1932, No. 22970. [Class 83 (iii).] In a method of cutting spiral bevel gears by means of a cutter of the type described in Specifications 214,738 and 279,166 the cutter b, Fig. 1, is set up so that the tangent to the cutter helix at the central cutter tooth lies along the tangent to the central spiral of the bottom of the tooth space to be cut in the blank c, the cutter being moved across the blank in the direction of arrow e and at the same time twisted angularly in the direction of arrow g so as to maintain the relative positions of the cutter helix and blank tooth curve throughout the operation. The cutter position may be slightly modified by setting it to a curve on the pitch cone or on a cone through the lowest line of action of the bevel gear teeth in use. The cutter and blank are rotated in timed relation and allowance is made for the spirality of the gear teeth by superposed rotation of the blank by means of differential gearing. In a machine embodiment Fig. 3, the main slide 2 supports in bearings 33 the headstock bracket 3 which is rotatable about a horizontal axis 4 and carries a head 5 with a cutter 32 adjustable about a transverse axis 6. The work head 9 is mounted on a swivel plate 8 carried by a cross slide 7. The main driving shaft 12 is connected through shaft 14 bevel gearing 21, shafts 22, 24, 28 and internal gearing 29 to the cutter spindle 31. The work is also driven from the shaft 14 through change gears 41, shafts 42, 44, differential bevels 46, shafts 48, 50, 52, 54 and worm gearing 55. The cutter is fed across the blank by movement of the slide 2 which is obtained from the shaft 44 through worm gearing 61, feed shaft 63 change gears 64, clutch shaft 65 and feed screw 68, the clutch 66 being operated by a rod 67. The superposed rotation of the blank to allow for the spirality of the teeth is obtained by change gearing 71 connecting the main screw 68 to the shaft 72 driving the bevel 76 of the differential gearing. The twisting movement of the cutter in the direction of arrow g, Fig. 1, is derived from the feed screw 68 which is connected through change gears 81 and worm gearing 83 to the spindle 86 of the headstock bracket. The train 81 is disconnected while the cutter is set to the desired angle before the beginning of the operation. Specifications 214,738 and 279,166, [both in Class 83 (iii)], also are referred to.
