Filed: 1920-05-21
Abstract: 143,577. Doehler Die-Casting Co., (Assignees of Kralund, J., and Stern, M.). Aug. 10, 1917, [Convention date]. Actuating by steam, air, and gas pressure; lever-actuated pumps; pumps for molten materials.-In a die casting-machine, the connexion between the operating piston e and the plunger c for forcing the metal is arranged to convert constant into variable speed and power. The pistonrod e<1> is connected by a link h to the long arm of a lever g, pivoted almost in line with the rod e<1>, and engaging, by its short arm, the plunger c which in its withdrawn position rests in guides b<2> and is free from the cylinder b to allow this to fill with metal. Steam or air is admitted to the cylinder d by a valve k which is oscillated by a handle p<1> as controlled by a stop p<2>, Fig. 5. In one position of the valve, fluid is admitted through ports &c. i, m, n, n<1>, j<2>, j<4>, and exhausted through ports &c, j<5>, j<3>, k<2>, k<1>, and the plunger c forces the metal into the mould rapidly at first, then more slowly and with increasing power, the larger the casting the greater being the final power applied. In the other position of the valve, fluid is exhausted through ports &c. j<4>, j<2>, k<2>, k<1>, Fig. 5, and admitted through ports &c. i, m, n, n<2>, j<3>, j<5> so that the plunger c returns slowly and splashing of the metal is avoided.

IPC: B62B3/06
Filed: 1916-10-06
Abstract: 109,675. Morris, Ltd., H., & Shelly, J., and Butterworth, J. A. Oct. 6, 1916. Hand-trucks with lifting-platforms adapted to be run under the load. For raising and lowering the platform, the post d of the steering-wheel c is given a vertical sliding movement by a rack- and-pinion or equivalent mechanism preferably actuated by the steering-handle. A cam or toggle lever effects the simultaneous movement of the rear part of the platform. The post d slides in bearings e fixed to the platform a and also in a sleeve f carrying a shaft w upon which the steering and actuating handle h is pivoted. The post d is caused to turn with the sleeve f for steering, by a key x, and is formed with a rack H engaged by a pinion C on the shaft w which can be rotated in either direction by the handle h by the engagement of a two-way pawl y with a ratchet z. The pawl y is controlled by a hand-lever B and rod A. The platform may be locked in the raised position by a pedal-controlled pawl mounted on the sleeve f and engaging a ratchet on the shaft w or as shown by a sustaining brake device which consists in mounting the pinion c on a screwed part of the shaft w so that the reaction of the weight through the post d causes a ratchet-wheel D, engaged by a pawl G, to be gripped between the pinion and a collar f and on the shaft w. The handle h may be used only for elevating and depressing the platform, and a separate steering- handle be provided. The platform may be supported at the rear by cams r mounted on the rear axle and actuated with the post d by the rod l and bell-crank j or by a cable. A toggle lever p, Fig. 7, may be substituted for the cam r. Radiusrods t or slides may be provided for guiding the movement of the platform.

Title: New or improved operating means for variable electric condensers, variometers and like instruments
IPC: H03J1/14
Filed: 1925-06-02
Abstract: 246,713. Laughton, G. A., and Curry, F. J. June 2, 1925. Wireless tuning-apparatus, adjustment devices for. - Operating means for condensers, variometers and like instruments comprise the arrangement in which 'the instrument spindle is adapted to be rotated either at a slow speed from a setting knob through reduction gearing mounted in or upon a rotatable, but frictionally held, cage or directly by bodily rotation of the cage together with a dial to which the knob is also connected through gearing. The instrument spindle c carries a bush g rotatable in the lower plate h<1> of a cage formed by plates h<1>, h<2> the cage being gripped by a friction device j<1> carrying shoes j. Fast on the bush g is a gear wheel k meshing with a pinion l on a spindle which is rotatably mounted within the cage. The spindle carries a gear wheel l<1> meshing with a pinion m on a similar shaft on which is a gear m<1> engaging a pinion n on a shaft o carrying a knob q. To provide for uniform movement of the dial p, the spindle carrying the pinion l is extended without the cage and carries a pinion r meshing with a gear s secured to the dial p and through which the shaft o passes without touching. For fine adjustment, the knob q is rotated and drives the spindle c slowly through gearing n, m<1>, m, l<1>, l, k, and the dial p in the same direction and at the same speed through gearing r, s, the cage meanwhile remaining stationary owing to the shoes k. For coarse adjustment, the dial p is rotated by means of its fingerpiece p<1> and as no force is applied to the gears, the cage, dial, and spidle rotate together against the frictional force of the shoes j. In the form shown, the knob q will rotate the spindle in a direction opposite to its own, but another gear could be provided to correct this. The shoes eliminate and risk of damage to the parts if stops and used to limit the travel of the spindle. The wheels k, l<1>, m<1>, s are identical and those l, m, n, r are identical to facilitate production.

Abstract: 1374111 Shearing METAL BOX CO Ltd 26 April 1972 [11 May 1971] 14306/71 Heading B3W [Also in Division B8] A cutter unit for use in slitting a sheet into parallel strips comprises a rotatable shaft 3, a plurality of annular cutters 6 coaxial and rotatable with the shaft and each having a flat cutting face 6a at right angles to the axis of the shaft, each annular cutter being inset in the periphery of a cutter disc 13 with the periphery of the disc and the cutter coterminous and with the cutter face 6a located in the plane of the flat face of the disc 13 and means such as sleeves 8 to locate the discs 13 in axially spaced relation. As shown, a sheet is fed by chains 1 and pushers 2 along a path P1 to a gauged slitter C1 and the resultant strips are deposited by a drop transfer device T on to a second carrier 1a 2a which feeds them along a path P2 to a second gauged slitter C2, fingers F1, F2 engaging the trailing edge of the sheet and strips respectively to increase the linear speed of the sheet and strips to the peripheral speed of the cutters 6. If parallel sections of a sheet to which lacquer has been applied are not strictly perpendicular to the leading and trailing edges of the sheet, sheet-contacting bars (F12), Fig. 11 (not shown), mounted on the fingers F1 are adjusted to make the direction of movement of the sheet through the cutting mechanism parallel to the sides of the lacquer panels. At least one role 58, Fig. 12, which may be magnetic, and a pair of pinch rolls 60, (61), Fig. 2 (not shown), tend to move the sheet against a guide cam 55, and a fence 59. Freely rotating magnetic rolls (not shown) guide the strips along path P2, a magnetic bar (62) Fig. 15 (not shown), replacing the cam 55. Auxiliary draw rolls (AR), Fig. 2, feed the slit strips to the drop transfer device T, a strip S1, Fig. 20, arriving first at position SIW with the edge 76 which will be the leading edge in its travel along path P2 resting in a slot 84 and its trailing edge 78 resting on a ledge 66 on a pivotable bar 64 and against a chamfered face 82 on a fixed bar 63 which ends in stripper fingers 79. The bars 64 are mounted on rocking spindles 74, (75), Fig. 17 (not shown), and are pivoted in turn to allow the strips to fall into the path of pushers 2a of the second conveyer by movement of a plate 85, through cranks 88-90. Cams 86 mounted on the plate 85 each cooperate with a cam follower 87 on a respective rocking spindle 74, the cam followers being progressively angularly displaced relative to the drop bars 64 to cause their operation in sequence. Each spindle is conected by linkage 71- 73 to a shaft 70 supporting pushers 67 spaced along each bar 64. The pushers are in position 67a when a strip arrives at the drop transfer device and are moved to position 67b to push the strip towards the path P2 when their associated bar 64 is rocked to drop the strip off the ledge 66.
