Title: Improvements in or relating to winches or the like
IPC: B66D1/12
Filed: 1922-04-13
Abstract: 178,463. Br³ll, K. April 16, 1921, [Convention date]. Jib cranes.-The swinging of a boom is performed bv the electrical control of a deck winch. Three drums, each provided with a separate clutch and brake, are mounted loosely on a common shaft 4 driven by spur gear from the main motor 1. The drum 5 performs the hoisting and lowering operations, while the drums 6, 7 manipulate the boom. An auxiliary motor 14 can be used to drive one or other of two countershafts 18, 19 by manipulating clutches 18<1>, 19<1> applied by solenoids 21 and released by weights. When the shaft 18 is driven in one direction, cams thereon engage the clutch and release the brake on the drum 5, thus allowing the drum to be driven from the main motor for hoisting or lowering. When the shaft 18 is driven in the reverse direction the clutch is released and the brake applied. On the other hand, when the shaft 19 is driven in one direction or the other, one or other of the boom-controlling drums is clutched to the shaft and the brake released, leaving the other drum braked and loose on the shaft. The main motor operates to rotate the clutched drum and wind in the rope to swing the boom, leaving the other drum to pay out rope under braked control. The operating-lever for the motor 14 is provided with a " gate " to prevent the possibility of both shafts 18, 19 being operated simultaneously. The winch is designed so that a single operator can manipulate the gate control with one hand and the controller for the main motor simultaneously with the other hand.

Abstract: 354,708. Arc rupturing in switches. HOLDEN, F. and MEASUREMENT, Ltd., Townsend House, Greycoat Place, London. April 4, 1930, No. 10764. [Class 38 (v).] A switch for breaking relatively large currents in prepayment meters has a thin contact-blade movable through a narrow air gap in a magnetic blow-out circuit to butt against and so make contact with a resilient contact-member disposed at one side of the gap, the blade being moved in the opposite direction under the action of a spring or equivalent device, breaking contact with the resilient contact-member. As shown in Figs. 1 and 2, the contact-blade f, carried by a spring- controlled arm g is moved through a narrow air gap of a magnetic blow-out to engage a resilient contact-blade j. The magnetic circuit of the blow-out, which may include a portion of the meter casing also includes a core a, bracket band polepiece d, an exciting winding n in series with the switch circuit being wound around the core a. Alternatively a permanent magnet may be employed Fig. 4 (not shown). Insulating caps k are mounted on the polepieces between which the blade f moves and these also serve to limit the motion of the contact spring j when the blade is moved to open the circuit. The elasticity of the blade j may be reinforced by a steel blade spring m mounted to bear on its rear face. The switch is tripped to open by means of the prepayment mechanism.

Title: Improved manufacture of bottle caps
IPC: B21D51/46
Filed: 1938-04-13
Abstract: 500,243. Shoots. JENSEN, E., and KJOLLER, C. J., (trading as INTERESSENTSKABET TANNY). April 13, 1938, No. 11429. Convention date, April 15, 1937. [Class 78 (i)] [Also in Group XVII] A machine for manufacturing bottle caps contains a device for regulating the supply of caps from the blanking and forming press to removal means, which device renders the press inoperative whilst the number of caps awaiting removal exceeds a predetermined amount. The normal speed of the press is adjusted so that more cap blanks are delivered in a given period than are removed by the removal means. In the device shown caps formed by the punch 1 fall by gravity down the shoot 4 and are removed by the intermittently rotating drum 6 with fingers 7, and are transferred to a belt 5 to which intermittent motion is imparted by the ratchet device 56, 46. The ratchet device 47, 48 and the lifting cam 55 keep the belt under tension whilst it is stationary. The caps are moved under devices 30 and 31 for inserting, respectively, adhesive substance and cork discs (or foil), and are finally conveyed to a heating table on which the adhesive is solidified. Associated with the shoot 4 is a finger 10, which by means of the lever 12 and a cam 14 on the flywheel 2 of the press, is caused to reciprocate through a hole in the bottom of the shoot. This finger, by means of a cable 16, is connected with a detent 19 engaging a lever 21 to which is linked an arm 26. When the lever 21 is disengaged from the detent 19, it is caused to oscillate between the stops 22, 23 by means of the spring 24 connecting it with the oscillating lever 12, The arm 26, when in the extreme left-hand position (as shown), causes the spring-loaded key 28 to be pressed into the driving shaft 27, thereby disconnecting the shaft from the flywheel 2 of the press tool. When the accumulation of caps in the shoot 4 is below the limit allowed, the finger 10 enters the shoot and by means of the cable 16, disengages the detent 19 and thus allows the lever 21, and consequently the arm 26, to oscillate from left to right. In these circumstances, the arm is moved away from the shaft 27 whenever the key 28 approaches the right-hand side, and fails, therefore, to press the key out of engagement with the flywheel, so that the press continues to operate. When a sufficient number of caps have accumulated in the shoot 4, the finger is prevented from oscillating by means of a cap blocking the hole in the shoot, and the detent 19 remains in engagement with the lever 21. The lever 21 and arm 26 are thus held in the left-hand position, in which position the arm 26 presses the key 28 back into the shaft 27, thereby disengaging the flywheel and throwing the press out of operation.
