Filed: 1945-11-23
Abstract: 613,120. Feeders for furnaces. HARTFORD EMPIRE CO. Nov. 23, 1945, No. 31646. Convention date, Aug. 28. [Class 78 (i)] [Also in Group XII] A feeder for glass batch, Fig. 1, comprising a batch chamber 3 with an outlet; a batch pusher 24 comprising an arcuately-curved member 25; a lever 34 fixed with relation to the pusher so as to oscillate the pusher in the chamber toward and away from said outlet about an axis 30 coincident with the axis of curvature of the pusher; a crank 49; a connecting rod 54 having one end mounted on the crank 49 and the other adjustably connected to the lever; said connecting rod including a spring 61 arranged to be compressed if the pusher is obstructed in its movement toward the cutter so as to allow the movement of the pusher to be halted, without halting operation of the crank. Fig. 1.-Carriage 11 is moved up to the opening 93 of the furnace and glass batch is supplied to chamber 3 through shoot 84, and pushed inside by pusher 24 moving in a curved path between arcuate surfaces 25. Pusher 24 is attached by lugs 40 to the pair of lever arms 34 which pivot at 30. Power is transmitted. from motor 8 through shaft 44 to shaft 47, Fig. 3, which rotates eccentric 49 and through connecting rod 54 pivoting on pin 63 swings lever arm 34 about its pivot 30. Fig. 3.-Rod 52 has thread 53 for adjustability of length and carries nut 60 and spring 61 so that, if the forward swing of the pusher is jammed, the spring will yield as the rod moves downwards and damage will be avoided. Length of stroke of the pusher 25, Fig. 1, is varied by handle 70 which rotates simultaneously, the two screws 65 which are coupled by chain 69, and varies the positions of pivot pin 63 in slot 64. Adjustable springs 73 are attached at 74 to lever arm 34 and effect the return stroke of lever arms and pushers. Fig. 5.-The pusher 24 passes through an aperture which is in the lower extension 79 of the shoot 84 and which has cleaning means 82 secured therearound so as to wipe the surface of the reciprocating pusher. Asbestos gasket 114 is secured around the outlet from the feeder so that good contact may be made by the batch feeder with the furnace surface and so splashing is avoided. The furnace opening 93 may be cooled by water introduced through pipe 105 and circulated through hollow frame 95 and passed out through 106. Cool air may also be passed through pipe 108. Rail support.-The batch feeder runs on wheels 12 on rails 14 and is held stationary by a screw 18 which bears against axle 19. The screw works in block 20 on bar 21 which is pivoted at 23 to the rails so as to be swung downwards out of the way when the screw 18 is to be released for the feeder to be moved away.

Filed: 1922-11-20
Abstract: 196,575. Leperre, E. F. A. C. April 24, 1922, [Convention date]. Reciprocating and oscillating machines. - The pistons of a compressor comprising two axiallydisposed cylinders constitute the cores of electromagnets, and the cylinders carry solenoids by which the pistons are actuated. The Figure shows a compressor having two such pistons 1 connected by a copper rod 10 and reciprocated by solenoids 3 carried on the bronze pump-barrels 2 and energized alternately. Air is drawn in through longitudinal grooves on the pistons which at their ends are furnished with cup-leathers 7 held in place by removable end pieces 8 which are also grooved and are formed with air passages by which cup-leathers are distended during the compression stroke. The compression spaces are closed, by soft iron discs 19 formed with apertures controlled bv rubber valves 21 or ball valves, the air being delivered into connected spaces 24, 24<1>. The switch controlling the windings comprises a frame 11 pivoted on an axis 12 and moved in opposite directions by projections on the pistons to cause toggle levers 14, 15 to be turned about their ends and the toggle joint 13 to make contact with one of two screws 18, 18<1> alternately. Excessive pressure acts on a diaphragm 26 and through a spring-pressed rcd 27 reverses a toggle-switch to cut both solenoids out of the circuit. In place of the pistons forming the magnets, they may be carried by extensions of the magnets and may be of less diameter so that a greater pressure may be attained. According to the Specification as open to inspection under Sect. 91 (3) (a) a single magnet piston may be used, the return stroke being effected by a spring.

Title: Current collector device
IPC: B60L5/30
Filed: 1961-09-07
Abstract: 951,133. Current collectors. BROWN, BOVERI & CO. Ltd. Sept. 7, 1961 [Sept. 7, 1960], No. 32188/61. Heading B7L. A current collector, e.g. for electrically driven vehicles, comprises two arms 11, 12, Fig. 1, pivotally connected together, which are both maintained at the same slope to the horizontal, but in opposite directions, the lower arm 12 enclosing a shaft 7 and its bearings, the shaft being used to raise and lower the upper arm 11 by means of bevel gears keyed one at each end to the shaft, and lifting means for raising and lowering the lower arm and thus the upper arm through the intermediary of the shaft 7 and bevel gears. The lower arm 12, Figs. 1, 3, is pivoted on fixed axle 2 at one end and its other end is pivotally connected to the upper arm 11 which has two branches joined at their far ends by a bow conductor 20. The structure is supported on insulators 22 and the current flows through a cable (not shown) to the inside of the vehicle. The arms 11, 12 are urged upwardly by the action of springs 18 pulling on chain 17 or ropes or cables fed round and secured to eccentric 16 rigid with the arm 12. A bevel gear 1, Fig. 3, is keyed to the fixed axle 2 and meshes with a bevel gear 6 keyed to a shaft 7. Thus as the arm 12 is raised the shaft 7 rotates and this rotates a bevel gear 10 at the upper end of the shaft, and causes the arm 11 to move upwardly as a bevel gear 10 keyed to axle 9 rigid with the arm 11 is also rotated. The ratio of the gears 1, 6 is one half of the ratio of the gears 8, 10 so that the arms 11 and 12 remain at the same inclination to the horizontal. The box conductor 20 may be manually lowered by use of a pull rope 19. A parallelogram type pantograph may be constructed by coupling two of the devices shown in Fig. 1 arranged opposite to one another, to the bow conductor 20 (Fig. 4, not shown). As an alternative to the springs 18 a pneumatic or electromotor drive may be employed. In the embodiment shown in Fig. 6, the lower arm 12 is raised by a coil spring 18 wound round the shaft 7 and held under torsion between a protuberance 13a fixed to the arm 12 and a lever 27 keyed to the shaft 7. The embodiment shown in Fig. 8 also employs springs 18 held under torsion but in this case, these act on bevel gears 31 which mesh with bevel gears 32 rigid with the lower arm 12. The gears 31, 32 may be such that when the arm is raised the gear ratio between them alters. This is shown in Fig. 9 where the gear 31 is a toothed elliptical segment and the gear 32 is a toothed segment with the teeth cut on a spiral in the axis of rotation. The springs 18 in Fig. 8 may be replaced by torsion rods. In the embodiment shown in Fig. 12, the arm 12 is also raised by coil springs under torsion, 40, and these are disposed on an axle parallel to that on which the arm 12 is pivoted. They rotate an elliptical tooth gear segment 37 which meshes with a complementary segment 38 rigid with the arm 12.
