Abstract: 856,575. Lace-machines. TULLMASCHINENBAU KARL-MARX-STAAT, VEB. May 24, 1957, No. 16525/57. Class 74 (1). The longitudinally shoggable warp thread rails 1, 2 of a plain-net lace machine are located on swingable arms 3 and 4, 4a by pins 7 which take into holes 6 in the free ends of the arms; and they are prevented from moving upwardly by horizontally disposed projections 13, 14 provided on the comb bars 11, 12. Horizontally extending pins 25, 26 borne on supports 23, 24 can be entered into downwardly opening U- shaped slots 19, 20 in plates 15, 16 at the ends of the rails; and, by reason of a spring 28 which urges the supports apart, the pins are moved into other U-shaped slots 17, 18 which open, towards the centres of the rails, into the slots 19, 20. The rails are thus secured in position. Rods 22, bearing the supports 24, are connected with a patterning device 27. The opposing supports 23 are carried on rods 21 encircled by the springs 28 and bear projections 29 engaged by a flank cam 30 which, when rotated by a handle through a worm and worm-wheel 35, 34, moves support 23 towards support 24 until the pins 25, 26 lie in the slots 19, 20 and the rails 1, 2 may be removed, provided that the coacting bars 11, 12 have been moved to carry away the projections 13, 14. To permit lateral displacement of rail 2 away from rail 1, as when re-threading broken threads, the arms 4, 4a are provided, with elbow joints 38, so that they may be bent, Fig. 6, against the action of springs 39, by means of a rope 41 to which the rotatable wormwheel and cam bush 32 act as a capstan. Rotation of the flank cam, whilst the bars 11, 12 are in operative position, is prevented by projections 48, 49 which take into recesses 46, 47 in the flank cam plate. A lip 50 on the cam plate actuates a switch 51 when both rails 1 and 2 can be withdrawn, and a switch 52 when the rail 2 can be withdrawn: the switches may operate lights.

Abstract: 728,485. Baling machines. ALLIS-CHALMERS MANUFACTURING CO. June 18, 1953 [Aug. 7, 1952], No. 16914/53. Class 94 (1). A baling machine of the kind which rolls a cylindrical bale between tensioned belts has an attachment whereby the initial rolling is carried out under negligible tension to produce a "soft-centre" bale. The attachment may be applied to a baler as described in Specifications 594,422 and 594,421, [Group 1], in which the bale 49 is rolled between belts 28 and 31 passing over tensioning rollers 6 and 12 mounted on pivoted arms 7 and 11 linked by rods 34. Springs 37 bias the arms 7, 11 in the tensioning direction. The arms 11 pivoted at 74 carry a shaft 24 with pinions 23 fixed to it, the pinions engaging fixed racks 22. The shaft 24 carries pawlplates (not shown) for driving in the clockwise direction as shown, drums 56. The drums are surrounded by adjustable brake bands 57 to which are secured arms 58. Pins 61 fixed to the arms 11 travel in the space between the bands 57 and arms 58 and are limited in travel by fixed stops 67 and adjustable stops 64. As a bale begins to build up, the belts 31 pull the rollers 12 upwardly from the position of Fig. 2, causing the pinions 23 to be rotated by the racks 22 with consequent rotation of the drums 56. The bands 57 rotate with the drums and thus there is little resistance to movement of arms 11 and little tension on the belts 28, 31. When the pins 61 contact the stops 67, as in Fig. 1, the bands 57 are checked, and brake the drums 56, thereby applying tension to the baling belts. When a complete bale is discharged, the arms 11 drop, the shaft 24 rotating free of the drums 56. Springs 76 return the drums and bands to starting position. Holes 66 are provided in the arms 58 enabling the pin 64 to be positioned to give various amounts of "soft centre" or none at all.
