Title: Improvements in or relating to Explosive-Actuated Fastener Driving Devices
IPC: B25C1/08
Filed: 1967-07-11
Abstract: 1,186,407. Explosive-actuated fastener driving tools. U.S.M. CORP. 11 July, 1967 [12 July, 1966; 9 Nov., 1966], No. 31816/67. Heading B4C. An explosive-actuated device for driving fasteners, such as nails 26, into hard material comprises a barrel 14 having an anvil 32 at its breech end which is movable between open and closed positions, a vent 38 communicating a chamber for an impact-explosive charge with the bore of the barrel, and a firing mechanism having a pin 44 adapted to strike the charge mounted on the anvil. The anvil 32 is held against the end of the barrel by means of a member 30 in which a sleeve 40 is mounted. The firing pin is mounted in a holder 42 which is slidable in the sleeve 40 and carried by a member 52; a striker 56 is slidably mounted in the latter member and loaded by a spring 58. In operation, when the muzzle end of the barrel is pressed against a workpiece S, the member 52 is moved rearwardly as shown in Fig. 1 to compress the spring 58. Upon depressing a trigger 66 a sear 76 is released from a slot 72 in the member 52, thereby allowing the striker to impact the firing pin and so fire the explosive charge 36, the explosive gases acting on a plunger 18. In order to re-load the device, the barrel is pulled outwardly taking with it the member 52 by means of pivoted levers 86 so as to allow the sear to re-engage the slot 72. When the position shown in Fig. 3 is reached, the levers 86 drop into a recess 99 formed in a housing 10 thereby allowing the barrel to be completely withdrawn for reloading. In a modification, the chamber for the explosive charge is formed in a recess (128, Fig. 8) provided in a shroud 120.

Title: Improvements in and relating to transitory electroresponsive control apparatus
IPC: H02H7/22
Filed: 1949-12-22
Abstract: 664,907. Electrically-tripped switches. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 22, 1949. [Dec. 30, 1948] No. 32840/49. Class 38 (v). In order to prevent "pumping" of the reclosing solenoid of a circuit-breaker, irrespective of whether a master switch is held closed or not, the solenoid, when energised, is arranged to open its own energising circuit. A relay 16 has two windings 80, 81, the latter normally being short-circuited by a switch 103 and the former being energized on closure of a push-button master switch 112, so as to move the core 69 down and pivot a lever 72 clockwise about its pivot 73 against the action of a spring 76. A plunger 120 resting on the left-hand end of lever 72 is thereby raised to extend a toggle 52, 53, and the switch 103 is opened by a member 107. Link 52 has a fixed pivot 54 and is shaped to engage a roller 60 on the end of link 53 which is formed by two spaced arms, the free end of link 52 being movable in the space. Extension of the toggle pivots a contact arm 30 clockwise to close contacts 27, 28 in the circuit of winding 12 of solenoid 10, auxiliary contacts 42, 43 being closed at the same time to complete a lock-in circuit for winding 80. Energization of winding 12, lowers the core 13 to close the circuit-breaker and an extension 98 of the core pivots a lever 94 clockwise to raise a plunger 85 against the action of a spring 91 and so lift link 52 from roller 60. The toggle is thus broken and the arm 30 is swing counter-clockwise by a spring 48 to open the contacts 27, 28 and 42, 43. The winding 12 is thus de-energized and spring 91 restores the plunger 85, lever 94 and core 13 to their original positions. If the push-button 112 has been released, the winding 80 is also de-energized and the links 52, 53 move back to the Fig. 4 position and re-engage. If however, push-button 112 is still depressed, the winding 80 is energized by the reduced current through the current limiting winding 81 which is placed in circuit when the contacts 42, 43, which normally short-circuit it, open. The links 52, 53 then remain in the Fig. 6 position until the windings 80, 81 are de-energized by opening switch 112.
