Filed: 1938-03-07
Abstract: 513,469. Preheating furnace charges. ALLEN & CO., Ltd., E., and ANDREWS, H. March 7, 1938, No. 7115. [Class 51 (ii)] In a furnace charge preheater of the kind in which the waste gases are drawn through a layer of material during its progress over an inclined grate 4, a hopper 6 is provided beneath the lower end of the grate in which the material accumulates and prevents passage of the gases to the exhaust 8 except through the material on the grate. From the hopper 6 the material may pass through a shoot direct to the furnace 1, or as shown an oscillating tray 14 is fitted to control the feed. The inclination of the grate may be adjusted about the axis 11 by the screw and nut 13, and the thickness of the layer of material delivered to the grate may be varied by the pivoted shoot 5.

Abstract: 704,393. Watches. SMITH & SONS (ENGLAND), Ltd., S. May 23, 1952 [March 28, 1951], No. 7188/51. Class 139. An automatic winding mechanism for watches comprises an oscillatory mass, a first gear wheel rotation of which is adapted to wind the mainspring, a second gear wheel, said first and second gear wheels being geared together and lying in a common plane, a member adapted to be reciprocated upon oscillation of the mass, gear means carried by said reciprocable member and adapted to mesh with the first. and second gear wheels and click means co-operating with said gear means so arranged that during motion of the reciprocable member in one direction one of the gear wheels is directly driven thereby and during motion in the other direction the other gear wheel is so driven. The weight 1, Fig. 2, oscillates about a pivot 2 and through an eccentric 5 reciprocates a member 6 carrying two pinions 7 and 8 prevented from anti-clockwise rotation by checks 9 and 10 respectively. The pinions 7 and 8 constantly mesh with gear wheels 11 and 12 respectively. The gears 11, 12 are interconnected by a gear 13 on the winding arbor. As the member 6 moves to the right the pinion 8 rotates the gear wheel 12 anti-clockwise so driving the gear 13 clockwise and winding the mainspring. As the member 6 moves to the left the pinion 7 rotates the gear wheel 11 anticlockwise again driving the gear 13 clockwise.

Abstract: 144,406. Sharp, F. C. March 22, 1919. Cupping.-In a cupping-press, the pressureplate a holds the work against the upward movement of the die c, with an inelastic but yielding pressure, such as caused by oil or like fluid in a cylinder q with a valve r to regulate the flow to the container q<4>. On the release of the pressure, a non-return valve q<5> allows the fluid to flow back into the cylinder q, until the slide n<2> carrying the plate a is arrested by an adjustable stop s. The plate a preferably surrounds the punch d, held in position by a cross-bar d<2> and worm-wheeloperated adjusting screws, above the die c mounted in a sliding table c operated by cams f<2> or eccentrics. A stationary peg i carried by a fixed cross-bar i<2> strips the work from the die c as it descends. The die may be arranged above the punch, and operated by toggle links, and in such case the chamber q<4> would be placed so as to cause the fluid to exert a filling pressure in the cylinder q.

[Also in Division H2] An instrument assembly for a vehicle comprises a housing 24, 26, 28, 30 and a number of electrical instruments (e.g. switches, meters or indicators) mounted in openings 46 in a plate 38 closing the housing, the instruments having electrical contacts mounted on their inner ends to engage mating fixed contacts provided within the housing in alignment with each opening. The instrument-mounted contacts are provided by prongs 52, and the fixed contacts by an insulating board 62 carrying conductors 64 and having holes 66 through which the prongs 52 pass to engage the conductors 64. The disposition of the prongs on each instrument is different, as shown in Fig. 4, and the same pattern of holes is provided in the board beneath each opening 46 so as to ensure that a particular instrument will be connected to the same pair of conductors 64 no matter in which of the openings 46 it is positioned. A multi-pin plug 68 (and Fig. 8, not shown) passes through an opening in the end wall 30 to make connection to conductors 64. An annular elastic gasket 56 surrounds the outer end of each instrument and is clamped between the plate 38 and an outer face plate 44 to provide a shock, vibration and weather proof mounting for the instruments. To prevent unauthorized removal or disconnection of the instruments the face plate is retained in position by a key-operated lock 96 and any screws affixing parts of the housing together, as 34, 42, are only accessible from inside the housing. Unauthorized removal of the plug 68 is prevented by a pin 84 which is held in position by the gasket of the first instrument and which passes through a hole in a tab 78 affixed to the plug.
