Title: A new or improved machine for inserting loops of cotton, thread or the like into textile and other articles for purposes of identification and/or for tying articles together
IPC: D05B5/00
Filed: 1929-07-26
Abstract: 335,314. Bamkin, J. W. July 26, 1929. Knot-tying devices; counting - mechanism, applications of.-In a machine for inserting loops of coloured cotton or the like into textile articles, for the purpose. of identification or for securing pairs or groups together, a needle inserts a length of cotton and a rotary device knots the loop. The machine may be fitted with a counting device. The illustrated form of the invention resembles generally an ordinary sewing machine with a reciprocating needle 15. The article b (e.g. the foot of a stocking) is inserted between the presser-members 24 and the plate 18 so that it contacts with the abutments 92, Fig. 6. The thread-end a is clamped between the cutter 27 and clamping plate 30. The machine is started and the needle 15 passes the thread through the plate 18 forming a loop c. The sleeve 43 of the wrapping device makes a partial revolution in the direction of the arrow, Fig. 8, and the finger 45 engages the thread loop. The needle then commences its up-stroke and the finger 45 is released to grip the thread, whereupon the sleeve 43 is rotated in the reverse direction. The grippers 82, 83 close upon the thread when the needle is fully withdrawn. As the gripper 82 moves, the thread is pulled to form the required length of loop. The feed-plate 18 is then moved to position the article beneath the needle, Fig. 10, and the cutter 27 frees the thread-end. The needle descends to form a second loop d, this loop passing through the material. The wrapping device operates as before, so that the finger 45 engages the thread loop, but instead of reversing its direction, it continues to rotate to wrap the thread round the tying bar 68 forming a loop. At the initial stage of the operation, the hook 76 is moved from its normal position, Fig. 6, to the position below the finger 75 of the bar 68 where it remains till the end of the wrapping action. At the end of this action, the bar 68 is moved endwise so that the hook 76 is exposed. The ends of the thread are laid between the ends of the tying bar 68 and the exposed hook. The hook 76 is then retracted, drawing the thread ends into the tying bar through the loop, so knotting the loop. The feed plate then moves back into its normal position. The counting mechanism may be connected with a lever located below the table so as to be engaged and actuated by the loop d. The articles may be counted singly, or in dozens of pairs, as in the case of stockings. In the example illustrated, the counting device 95, Fig. 2, has a scale wheel 97 turned by gears driven by a finger 111 engaged by the tacking loop.

Title: Improvements relating to railway fluid pressure braking apparatus equipped with automatic train control
IPC: B60T7/18
Filed: 1957-07-23
Abstract: 829,818. Fluid-pressure brakes. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd., and SIMMONS, A. W. July 17, 1958 [July 23, 1957], No. 23254/57. Class 103 (1). In automatic train control equipment for railway vehicles of the kind described in Specification 745,105, effective to vent a timing reservoir 11, and electromagnetically operated valve 37 is provided which controls either one or both of the operations of venting or recharging the timing reservoir, the valve 37 itself being of insufficient capacity to pass fluid at a rate demanded by the performance of the operations controlled, and carrying out such controls through a relay valve 15. When the automatic train control equipment is actuated on the wheel approaching an adverse signal, the electromagnetically-operated valve 37 is de-energized and the ball closure member 38 drops to close off atmospheric port 40 and to establish communication of pipe 28 with pipe 39 and hence with the main reservoir by pipe 27. Main reservoir pressure is thus applied to the underside of control piston 25 and the pressures of compressed fluid across the control piston arm promptly equalized so that the pressure of compressed fluid in the charged timing reservoir 11 acting on the valve actuating member 23, with the assistance of the spring loading the control piston 25, disengages the valve actuating member 23 from the valve closure member 22, which is then seated by its loading spring. The timing reservoir 11 is consequently placed in communication with atmosphere, through the pipe 14 and choke 24 so that compressed fluid therein is vented at the rate controlled by the choke. When the pressure in the timing reservoir 11 has been reduced to the predetermined degree, the valve 12 acts to interrupt communication between the brake pipe and main reservoir and the valve 13 brings about a reduction in the brake pipe pressure.

Abstract: 442,831. Feeding sheets. ROY, A. A., 94, Rue Louis-GuÚrin, Lyons, France. Aug. 23, 1935, No. 23734. [Class 100 (i)] Sheet separators.-For feeding sheets from a pile 2 to stencilling-machines a preliminary separating-device is provided in addition to the normal sheet-feeding devices, the preliminary separating-device acting to buckle a portion of the top sheet to permit the sheet below it to be held by a retaining or holding device while the top sheet is being fed. The pile 2, Fig. 1, is carried by a plate 1 and guided by a guide 3. A vertically sliding carriage 5 has pivoted to it a double-armed lever 8, which is oscillated from the stencilling-machine by a link 11, and a pair of corrugated rollers 9 are mounted in the lever 8 and act to buckle the top sheet when they are moved to the left by the link 11. Pawls 10 prevent rotation of the rollers 9 as they move to the left, and when the sheet is buckled a spring-pressed block 16 is allowed to descend on to the sheet below the top one and hold it until the feeding device has removed the top sheet. The block 16 is connected by a rod 15 to a lever 13 which is actuated by a pawl 18, connected to the link 11, to raise the block. A sloping abutment 20 acts on the pawl 18 and releases the block 16 when the top sheet has been buckled. On the return motion of the lever 8 the rollers 9 can rotate freely. By arranging the rollers 9 to act along one of the longitudinal side edges of the sheets the block 16 can be dispensed with, the feeding motion being parallel to the axes of the rollers 9. In a further modification, Fig. 10, for acting on the side edge, a friction roller 25 is pivoted on the carriage 5 and is rotated intermittently to buckle the sheet by means of a pawl-and-ratchet device operated by the link 11.
