Title: Improvements in or relating to starting devices for internal combustion engines
Inventor: HIGGINS JUSTUS
IPC: F02N3/02
Filed: 1957-02-18
Abstract: 816,257. Engine turning gear. QUALCAST Ltd. Jan. 31, 1958 [Feb. 18, 1957], No. 5399/57. Class 7(5) [Also in Group XXIV] Turning gear for an internal combustion engine comprises a hollow drum 5 fixed or adapted to be fixed to a rotary shaft of the engine such as the crank shaft or cam shaft, a stationary shaft 8 coaxial with the hollow drum, a pulley 11 rotatable upon the stationary shaft and having secured thereto one end of a cord or chain 13, resilient means 14 associated with the pulley and stationary shaft and biasing the pulley in a direction opposite to that of the rotation of the engine shaft so as to wrap the cord or chain about the pulley, a yoke member 17 rotatable under frictional constraint on the stationary shaft and carrying an eccentric shoe 16 pivoted to it about an axis remote from but parallel with the axis of the stationary shaft, upon a pivot pin projecting from the yoke member, and a driving member 15 offset from the axis projecting from the pulley and adapted so to engage the shoe remotely from its pivotal axis when the pulley is rotated against its bias in the starting direction relatively to the shaft and yoke member as to rotate the shoe about the pivot pin and to force a part of the shoe into engagement with the hollow drum whereby rotation of the pulley resulting from pulling the cord or chain therefrom is imparted to the hollow drum. As shown the hollow drum 5 is mounted on the magneto or fly wheel 7 of a twostroke engine, When the engine starts the drum 5 over runs the shoes 16, yoke 17 and pulley 11 and the shoes are no longer forced into contact with the drum 5 by the driving pins 15, If desired the shoes 16 may be fitted with springs connected to the yoke member in order to retract them. Friction washers 19 are preferably fitted so that rotation of the yoke member 17 relative to the shaft 8 is slightly impeded. Each shoe 16 is loosely pivoted by means of a bush 22 screwed on the pivot pin, so that it can not only rotate but also translate slightly relative to the pivot pin. Owing to the loose pivoting of the shoes they can rock slightly about whichever of their portions 23 and 25 first engages the inner surface of the drum so that the other of these portions is brought into engagement with the inner surface of the drum. The drum may be of aluminium and portions of the shoes may tend to bite slightly into the surface of the drum. The invention is applicable to engines for lawn mowers, in launches or in horticultural or agricultural machinery

Title: Apparatus for cutting meat in tins
IPC: B26D3/24
Filed: 1952-02-29
Abstract: 717,608. Cutting meat in tins. NORMAN & ELDRED, Ltd., and ELDRED, H. R. March 2, 1953 [Feb. 29, 1952], No. 5431/52. Class 5 (1). [Also in Group V] Apparatus for cutting meat, while in tins, into lengths, comprises means for clamping a tin on a rotatable table, means mounted on a main drive shaft for cutting the meat in the tin into lengths of the desired section, means for releasing the tin after the cutting operation, means for rotating the table through an angular distance to receive the next tin for clamping thereon, and means operating automatically for controlling the timed sequence of operation. A tin full of meat is placed in a recess 11 in the table 10 and is clamped by the cylindrical member 18 which, under the action of cams 25, presses on the rim of the tin, the pressure also holding the bottom of the tin in the recess 11 against the spring-pressed plate 12. A spring-pressed rod 50 is caused to engage one of a series of holes in the plate 10 by a cam 54, to lock it against movement during the cutting operation. The knives 17, radiating from a tubular member and supported from a plate 30 connected to a plate 33, are moved down by an eccentric 36 and rod 35 to cut the meat in the tin into lengths. As the knives rise again, a flange 19 on the member 18 and a disc 38 supported from it are held on the surface of the meat to form a stripper plate for the first part of the upward stroke, slits being provided in the flange 19 to allow the knives to pass. During the rest of the upward stroke the plate 30 meets the end of the member 18 which, on further movement of the cams 25, is raised and the tin released. At the same time a cam 14 raises the plate 12 to the level of the table 10. Simultaneously with the cutting operation and/or with the withdrawal of the knives an eccentric 48 operates a pump 45 to spray edible oil from a tank 57, through a spray ring 46, on the knives and stripper plate. At the end of the upward movement of the knives and clamping means a cam 44 strikes a radial projection 42, extending from the top of the vertical shaft 6 which carries the table, and moves the table through part of a revolution to bring the next full tin beneath the knives, the cam 54 moving simultaneously to allow the rod 50 to release the table. The apparatus may be mounted on wheels or rollers.
