Title: A safety control for coupling a driving structure to a driven structure
IPC: F16P3/12
Filed: 1939-09-22
Abstract: 536,726. Machinery guards. ZERUNEITH, R. E. Sept. 22, 1939, No. 26426. Convention date, April 13. [Class 80 (iv)] In a safety device for wire-stitching machines &c. in which a vertically sliding ring- guard 265, Fig. 1, descends on to the work, and if arrested by an obstruction, such as the operator's hand, stops the machine, the guard is lowered by a lever 269 and a spring 276 under the control of a cam 272 on the machine shaft 108, and its failure to descend fully allows a clutchlever 401, Fig. 2, to remain in a position to disengage the driving-clutch after only a portion of the cycle has been performed. The machine is driven from a rotating ratchet wheel 393 through a clutch-ring 386, which is pivoted to a disc 384 on the machine shaft, and has an internal tooth 391 adapted to engage the ratchet-wheel under the influence of a spring 388, when a detent 395 is withdrawn from an external notch 396 in the ring by the action of a solenoid 408 or a handlever. If the guard does not descend fully after engagement of the clutch the two-armed lever 401 bearing against the edge of the ring engages the notch 396 and forces the ring out of engagement with the ratchet-wheel after a quarter-revolution of the shaft. If the guard descends fully, the free end 301 of the lever 269 rocks the lever 401 out of operative position, so that the machine completes a cycle. Reverse rotation of the machine shaft under the action of the spring 388, after the clutch is disengaged, is restrained by one or the other of two detents 397,404 which engages a notch in the edge of the disc 384. In a modification, the clutch-ring 386 is replaced by a spring pawl 436, Fig. 6, which engages the driving ratchet-wheel. The machine is started by withdrawal of a spring plunger 438, which holds the pawl out of engagement. If the guard fails to descend fully, a second spring plunger 423, which is controlled by a cam 432 on the machine shaft, moves into the path of the pawl and disengages it. Wnen the guard descends fully, the plunger 423 is held in retracted position by a toe 419 on the free end of the lever 415 that operates the guard. The plungers 438, 423 may be controlled by electromagnets.

Title: Improvements in or relating to sliding clasp fasteners
IPC: A44B19/06
Filed: 1945-10-15
Abstract: 602,394. Sliding-clasp fasteners. CORNER, G. H. C.. and LIGHTNING FASTENERS. Ltd. Oct. 15, 1945, No. 26883. [Class 44] In a sliding-clasp fastener means are provided over a portion L1, L2, Fig. 2, of the length of the fastener for locking the fastener in any one of a number of partly open positions against further opening, the remaining portion N1 of the length of the fastener being so arranged that locking cannot be effected at any point, and the fastener opens fully when the stringers are pulled apart. Usually that part of the fastener where locking may be effected is at the upper or first opening part, and the locking positions may be arranged at closely spaced intervals and at more widely spaced intervals over different parts, L2 and L1 respectively, of this portion of the fastener. Locking is effected by a slider having a spring- pressed locking tooth or prong 12, Fig. 13, engaging between the elements ; at'that part of the fastener where locking is possible the spaces 10 between elements 7 are wide enough to admit the tooth 13, while over the other part the spaces 11 are too narrow. The entering end of the prong 12 is preferably slightly rounded. The slider may alternatively be of the kind described in Specification 357,072, in which case the elements are of such depth, width or thickness as to obtain the desired action. By this means the fastener can be locked in fully closed or in partly open position, as desirable in jackets &c. but cannot lock when opened beyond a predetermined point, so that damage to the fastener in attempting to remove a garment with the fastener not fully open is prevented. The fastener on a jacket, Fig. 4, for instance, has a locking part L and a non-locking part N. The fastener is made by the adaptation of known methods of manufacture to produce - and apply to the tapes elements of two or more different shapes, with varied spacing. Specification 433,139 also is referred to.

Filed: 1935-09-30
Abstract: 461,517. Steam-power plant. KRUPP AKT.-GES., F. Sept. 30, 1935, No. 26950. Convention date, Oct. 1, 1934. [Classes 110 (iii) and 122 (iii)] In auxiliary equipment for rapid-evaporation locomotive boilers &c. which is driven by an exhaust steam engine fed from the main engine without special regulation when steam is taken from the boiler, and which includes elements having characteristics differing substantially from that of the exhaust steam engine, the auxiliary equipment is divided into two groups, one driven by an electric motor at a low speed and the other driven by the exhaust steam engine which is automaticcoupled by a clutch &c. to the first group when its speed equals that of the first group. In the construction shown, an auxiliary exhaust. steam turbine is provided which is sufficiently powerful to drive the two groups of auxiliaries indicated, namely that permanently in operation and associated with the boiler, and that brought into operation when the main power plant is in operation. The movable grate driving-element, the blower, the boiler water-circulating pump F, and the boiler feed pump G are mounted on a shaft carrying an electric motor H which is driven by a battery through a regulator J. The air fan M of the condenser L is permanently connected to the turbine which, when its speed equals the speed of the motor H, takes over the drive of the other auxiliaries through an over-taking clutch P. The motor H is then disconnected, or it may remain in operation and, acting as a dynamo, recharge the battery K. In a modification, the turbine is connected to a fan and an electric generator which, when its voltage equals that of the electric motor, takes over the supply of current to drive the motor. The battery is then unloaded. In some cases the turbine may drive only an electric generator, and this through motors drive the auxiliaries, the auxiliaries associated with the condensation system being permanently connected up. The exhaust turbine may be subdivided into two or more turbines arranged in parallel or series, each of which can drive one or more auxiliary machines. The turbine may be supplied with main steam by a tube n<1>, to unload the electric motor.

As described the fastener is made from a long length of fastener forming strip, the strip consisting of two tapes each having a row of fastener members secured along one edge portion, the fastener members being interlocked; at intervals along the length of the fastener forming strip a said fastener is made by shaping the plugs by the application of pressure and heat by a shaping and punching tool to the plastics material of the interlocked interlocking members and/or the facing of plastics material which can be on one or both sides of the fastener stringers, at a position corresponding to one end portion of the fastener, the piece of wire gauze is placed on the fastener stringers in the region of the desired plugs, on one or both sides of the stringers and, at the same time as the plugs are formed, secured to the stringers by the plastics material of the interlocking members and/or the plastics facing or facings undergoing shaping, so that the plastics material fills the interstices of the piece or pieces of gauze, a part of the or each of which is incorporated in the plugs as they are shaped, the tool simultaneously separating the plugs as they are shaped. After the plugs have been formed the fastener lengths are separated from the fastener forming strip along a line and the socket which is made of plastics material is welded by heat and pressure to the right hand tape 1 by a lap weld between a lateral extension 9 of the socket and the fabric of the tape. The extension 9 of the socket also extends lengthwise of the tape and terminates in a hook 12 which engages the slider to retain the slider in position when the two stringers are separated by removing the plug 6a from the socket; the plug 6b remains in the socket. As an alternative to a plastics socket a metal socket can be used which is clinched to the plug 6b. The tool used for moulding the plugs is provided with teeth which engage between some of the interlocking members to position the fastener forming strip relative to the tool.
