Title: Bobbin Case for a Sewing Machine Loop Taker
IPC: D05B57/00
Filed: 1968-07-30
Abstract: 1,189,069. Sewing machines. SINGER CO. 30 July, 1968 [29 Dec., 1967], No. 36228/68. Heading D1G. A thread-carrying bobbin having a hub and at least one circular flange is rotatable in a bobbin case, a brake device, pivoted to the bobbin case about an axis parallel to the axis of rotation of the bobbin, has a portion adapted to engage the thread passing out of the bobbin case, and tensioning means carried on the bobbin case biases the brake device into engagement with the bobbin flange to place the bobbin thread under tension, the tensioning means having a guide means cooperating with slot means formed in an annular flange on the bobbin case and with the brake device to permit the thread emerging from the bobbin to pass about the threadengaging portion of the brake device, whereby drawing of the bobbin thread causes the brake device to pivot out of engagement with the bobbin flange. In Fig. 5 a bobbin having circular end flanges 116, 118 interconnected by a hub 114 is journalled in a case having an annular wall 110 extending from an end wall (104). A lever 126, pivoted at 132 in a slot 122 formed in wall 110, is formed at one end with a brake finger 128 and at the other end with an apertured finger 130. A leaf spring 134, secured intermediately to wall 110 by a screw 136, has one end 138 engaging finger 128 to bias the latter against flanges 118 for normally preventing rotation of the bobbin. Thread 120 from the bobbin passes through an aperture 142 in wall 110, through the aperture in finger 130, between the other end 140 of spring 134 and wall 110 to be tensioned thereby, and finally through an eyelet 144 in wall 110. Drawing thread 120 from beyond eyelet 144 thereby serves to shift finger 130 towards wall 110 and finger 128 away from flange 118 to permit rotation of the bobbin. In Fig. 9 a bobbin having a hub 214 interconnecting circular flanges 216, 218 is journalled in a case having an annular wall 210 extending from an end wall 204. The ring surface of wall 210 is formed with a groove 244 interconnecting apertures 246, 248 in wall 210. A lever 226, pivoted at one end at 232 in aperture 248, is formed at its other end with a transverse brake and thread-engaging finger 230. A leaf spring 234 is secured at one end to wall 210 by a screw 236a, is engaged intermediately by an adjusting screw 236b, and has a free end 238 engaging lever 226 to bias finger 230 against flanges 216, 218. Thread from the bobbin passes through an aperture 250 in wall 210, between wall 210 and a tensioning portion 240 of spring 234, under pin 230 and through aperture 246. Drawing of thread 220 thereby disengages pin 230 from the flanges 216, 218 to permit rotation of the bobbin. The arrangement may be used in the sewing machine described in Specification 1,179,964, in which, at the end of a stitching operation, the needle and bobbin threads are drawn by a hooked member and are then severed by a single knife blade.

Abstract: 1,016,134. Stacking machines; suction holding appliances; orientating articles. BRAYWOOD ENGINEERING CO. Ltd. Oct. 18, 1962 [Oct. 18, 1961], No. 37281/61. Headings B8C, B8H and B8S. A machine for stacking workpieces, e.g. tiles, by picking them up one at a time and depositing them on a rotatable support, which is turned through a predetermined angle about its axis after each tile is deposited, has a base 10 supporting a column 15 carrying a plate 20 with pressure cylinders 25, each containing a piston with a rod supporting a plate 26a and a suction pad 26, spaced 90 degrees apart around the column. The machine is fed by a conveyer 30 operated by a chain drive 31 from a motor, and tiles coming along the conveyer first operate a roller 67 connected to a stop 68 which allows the machine to deal with only one tile at a time, and then trip a switch 40 which actuates a valve 37 inducing a vacuum in one of the pads 26 and thus lifting the tile, which is also raised slightly by a plunger 41. The switch 40 also actuates a pressure cylinder 45 connected to the column 15 by a plunger 46 and crank 47 to impart a rotary motion to the column and with it the plate 20 thus swinging the tile through 90 degrees to a position over one of the rotatable supports 51 which are driven from the column 15 in one direction only by chain drives through clutches. The clutch housings carry spring- loaded plungers engaging in grooves on the undersides of the supports to locate them precisely after 90 degrees rotation, and each support carries a setter on which the tiles can rest. When a suction pad comes to rest over a setter the pad is lowered under the control of adjustable air bleeds 25a, an action which is initiated by one of a pair of switches being tripped by an arm on the column 15. The downward travel of the arm is steaded by guides 65 and limited by a switch 70 on the piston rod which is telescopically attached to the pad 26 to permit the rod to descend idly and overtravel when necessary. Each time a suction pad rises it acts on one of a pair of switches 71 on a plate 72 to initiate the next cycle with the other pads. When a desired height of tiles has been deposited on the setter the tiles operate a switch 75 which actuates a pressure cylinder 76 with a pusher 77 which feeds a new setter from a cartridge 78 on to the rotatable support, at the same time pushing the full one on to a receiving belt.
