Title: Improvements in or relating to the cutting of tubular fabric
Inventor: HARDWICK ALBERT RAYMOND
IPC: A41C5/00
Filed: 1968-01-13
Abstract: 1,250,001. Cuffing out garments. SAMCOSTRONG Ltd. 13 Jan., 1969 [13 Jan., 1968; 23 April, 1968], Nos. 2003/68 and 19081/68. Heading A3V. [Also in Division B4] A device for use in cutting-out shapes from tubular fabric comprises a former having a frame 4, 5, Fig. 1, which can be inserted into a piece of tubular fabric and which is shaped to hold such fabric piece in a desired shape, and a cutting die which is supported by the frame and provided with blade portions 2, 2a facing outwardly in both directions from the surfaces of the former. The blade portions 2, 2a are reinforced by strips 3 within the frame 4, 5, the latter being provided with graduations 6 so that the position of the frame in the tubular fabric can be determined. In the embodiment shown in Fig. 2 intended for cutting out a girdle from a tubular piece of elasticised material, the blades 11, 12, 20, 21 and secured in a wooden frame 10 made from separate pieces clamped together by means of nuts and bolts 18, 19. The blades 20, 21 are formed with a knife edge on one edge only, the unsharpened edge being supported by a steel backing plate (22 Fig. 4) screwed to the frame. In use, the frame is inserted into a tubular piece of material and the assembly then placed in a press so that, in a single pressing operation the blades cut through both sides of the material to form a girdle blank. The waste material, which is still attached to the girdle by small uncut portions, is severed from the girdle by an operator.

Title: Method of and apparatus for producing lengths of material
IPC: B21C35/02
Filed: 1937-03-09
Abstract: 502,016. Squirting. KAFOWI, J., and GOLDSCHMIDT, F. July 9, 1937, Nos. 19093 and 19094. Convention dates, July 30, .1936 and Sept. 23, 1936. [Class 83 (iv)] In a method of extruding articles such as tubes or rods, a billet is heated to a temperature near its melting point and is then subjected to a sudden impact action to force the material through the die of the extrusion press. An apparatus suitable for carrying out the method comprises a matrix a with a die b mounted beneath a plunger c from which depends a mandrel f. A second plunger d, d<1> slidable on the mandrel is attached to the plunger c by means of rods e so as to be vertically movable relatively to the plunger c. In operation the billet g is placed within the matrix and as the plunger descends, the mandrel passes through the billet and die b and the plunger d<1> becomes seated on the billet. The plunger part c<1> then strikes the plunger d<1> a hammer-like blow to effect extrusion. A severing plunger severs the rod or tube from any part of the billet remaining in the matrix. The Specification as open to inspection under Sect. 91 comprises also modified means for attaching the plunger d<1> to the plunger c so as to allow relative movement and in addition describes a suitable form of billet which tapers from the top to the bottom and has a cylindrical bore of greater diameter than the mandrel. This subject-matter does not appear in the Specification as accepted.

[Also in Division F2] An hydraulic motor for driving a vehicle wheel in a closed hydraulic transmission system (see Division F2), comprises two sets of cylinders, one set of larger capacity than the other, driving a common output shaft, and valve mechanism whereby either or both sets of cylinders can be placed in operation. In the embodiment of Figs. 4 and 5, cylinders of larger capacity 19L alternate with those of smaller capacity 19S, and their associated pistons drivingly engage a two lobed cam 17, through rollers 21 on arms 35 pivoted at 36 and spring loaded such that inoperative pistons are held at their top dead centres. Cam 17 is shaped such that the output shaft is driven at constant torque and constant angular velocity. Three speed ranges are obtainable by operating both sets of cylinders together or either set alone, a selected set of cylinders being rendered inoperative by supplying pressure to valves 24, Fig. 5, to move them leftwards against springs 25 to close valve ports 28 and connect cylinder passages 41 to exhaust passages 29. In the embodiment of Fig. 7, three cams 17, 17A and 17B are spaced axially along the output shaft and are drivingly engaged by pairs of pistons 59, 59A through arms 56 and rollers 21. The positions of the piston connecting rods 50, 60A on arms 56 result in cylinders 58 being of greater capacity than cylinders 58A. Valve means are provided for selectively operating either or both sets of cylinders. Springs may be provided to bias the pistons to their top dead centre positions.
