Abstract: 417,520. Threading buttons. CLARKSON, V. J., 29, Clarendon Place, Leeds. April 6, 1933, No. 10284. [Class 141.] In apparatus for threading buttons on to wires &c., the buttons are fed singly into a pocket fitted with two pairs of shutters which grip alternately the wires on to which each button is threaded after being brought into register therewith while supported on the upper pair of shutters. The buttons 1 are fed from a shoot 4 into holes 5 in a ratchet wheel 6 operated from a cam 11 mounted on a driving shaft 12, and presented to the pocket 15 provided in a support 7. The shutters 20 are mounted in guides 21 and are operated against the influence of a spring by a cam 27. The shutters 30 are similarly actuated, and are carried below the shutters 20, in guides 29. The buttons are brought into register with the wires by means of a head 36 adapted to be raised by means of a cam-actuated lever 37, and to be rotated under the influence of a spring 44 by a cam 17 mounted on the shaft 12. In operation, with a button resting on each pair of shutters 20, 30, the head 36 descends under the action of the lever 37 on to the button in the pocket 15 and the shutters 30 are opened to allow the button 1 resting upon these shutters to fall down the wires 22 on to the pile threaded thereon. During the continued rotation of the shaft 12, the shutters 30 close under the action of their spring to grip the wires 22, and at the same time the head 36 is rotated to position the button supported on the shutters 20, so that the button holes are in register with the wires 22. The shutters 20 are then opened to allow the button in the pocket 15 to fall on to the wires 22 down to the shutters 30. When the shutters 20 have been moved apart, the head 36 is lifted clear of the ring 6 which is then rotated another step to bring the next button into the pocket 15. The spring 44 then rotates the head 36 back to its initial position for the commencement of another operation.

Abstract: 720,382. Knitting-machines. LEBOCEY, R., COUSTE, J. H. J., LEBOCEY, A. L. S., and LEBOCEY, B. J. E. April 25, 1952 [April 27, 1951; April 18, 1952], No. 10487/52. Class 74 (2). [Also in Group XL (b)] The electric motors for high and low speed running of a circular machine are controlled by circuits which may be broken when influenced by electronic or photo-electric devices recording any irregularity in the machine operation or fabric to cause the machine to be stopped. Brake mechanism is also provided to assist in stopping the machine. The hand-control levers 7 of the machine are adapted to be placed in various positions, the action of which causes a chain 1 to rotate a segment 8 which influences rollers 32, 33 to cause contacts 34-35, 36-37, 38-39, 40-41 to make or break, thereby controlling the operation of the driving motors. A cam 18 integral with a ratchet wheel 22 is also movable to control a roller 28 influencing contacts 29-30 in the motors' circuits. A brake band 10 extends over a drum 12 on the driving shaft of the machine and is secured to the hub 9 of the cam 18 and ratchet wheel 22. Pawls 14 and 19 control the movement of the cam 18 and ratchet wheel 22, the pawl 19 being controlled by an electromagnet 26. The electromagnet is in the circuit of the electronic or photo-electric control devices which when actuated influence the pawl 19 to release the ratchet 22 and thereby cause the brake band to be operated at the same time as the segment 8 is moved to break the motor circuit and thereby stop the machine. Specification 713,677 is referred to.

Title: Improvements in automatic firearms
IPC: F41A19/02
Filed: 1946-04-04
Abstract: 610,284. Automatic firearms. PHIPPARD, S. R. April 4, 1946, No. 10490. Convention date, April 5, 1945. [Classes 92 (ii) and 119] A device is interposed between the trigger mechanism and the action of an automatic firearm for controlling the number of bursts when the trigger is pulled, the device being actuated directly by the action and being positively constrained from movement after each intermittent actuation by physical contact with the action. In the construction shown the breech bolt 7 has a recess 8 which provides a shoulder 9 for engaging faces a, b, c, d, on a rotatable control device 2. As shown, the bolt normally prevents rotation of the device 2 but when the recess 8 moves to a position above the device the latter is partially rotated by a -spring 20 and further rotated by the shoulder 9 as the bolt 7 recoils to bring the next face against the underside of the bolt. The trigger 15 is pivoted at 14 and carries a stepped connector 13 which actuates the sear 11, the latter being pivoted at 12 and carrying a spring 18a which bears on the undersurface of the connector and is connected to the trigger spring 17. When the trigger is pulled the sear is released from the bolt 7 and continuous fire takes place, the device 2 moving one step at each shot. When however a lateral projection 4 on one corner of the device 2 meets an extension 13b of the connector it depresses the latter and allows the sear to move upwards under the action of a spring 18. The connector may be moved laterally, whereby the mechanism may be arranged for single shots, continuous fire or in bursts as desired. The breech bolt recoils first against the action of a spring s and, near the end of its recoil, also against the action of a further spring HS.

Filed: 1917-07-23
Abstract: 110,332. British Westinghouse Electric & Manufacturing Co., (Westing- house Electric & Manufacturing Co.). July 23,1917. Electro-magnetic switches; protective arrangements.-An arrangement of relays and circuitbreakers for interrupting a circuit in the event of abnormal conditions, for example overload or reverse current, comprises a relay 5 operated by the winding 8 energized from a series transformer 4 in the circuit to be protected, a two-way electromagnetic switch with a winding 13 normally out of circuit but connected in series with the winding 8 on the occurrence of circuit conditions causing the closure of the relay contacts 10, 11, an inductive resistance 12 connected across the winding 13, and a trip coil 3 for operating the circuit-breaker 2. The electrical connexions are as shown. When with abnormal conditions the relay contacts are closed, the coils 4, 8 and 13 are connected in series and the switch member 15 is moved to the contact 18 thereby connecting the trip coil 3 in series with the coils 4, 8, and 13 and tripping the circuit-breaker. The inductive resistance 12 has a core 19 which becomes saturated when a current greater than that necessary to operate the switch member 15 traverses the circuit and, consequently, the resistance 12 serves to maintain a constant potential at the terminals of the winding 13 when the relay 5 has operated.
