Abstract: 618,964. Holders for discharge tubes. METCALFE, C., and SEXTON, R. May 2, 1946, No. 13322. [Class 38 (i)] A valve holder has folded resilient contact strips within shaped apertures in the base, arranged to press contact pins radially towards the walls of the apertures. The apertures 2 in the moulded base 1 are semi-cylindrical, or rhomboidal or of truncated triangular shape at their upper ends, with the arcuate walls 9 innermost and the outer walls 11 curved or ribbed ; whilst the lower end 10 is of rectangular cross section. The walls 9 are grooved longitudinally at 12 to receive the contact pins of a valve, and are countersunk at the upper ends 13. Ribs 14 may be formed between the apertures. The contact elements 3 are stamped from thin blanks of brass, Fig. 3, which are slotted at 18 and 24. The upper portion 25 is folded down at line 26 and folded again at line 29 to form the contact portion ; whilst the flanges 19 are bent up to form a channel-shaped soldering tag at the lower end. Alternatively the head may comprise a single loop. On inserting the contact into an aperture-with slot 24 facing the groove 12-the flanges 19 pass through the rectangular slot 10 and spring apart so that the curved edges 20 of the flanges 19 press against the under side of the base and pull the shoulders 21 on the contact firmly against the ledges 22 formed by the change of section in aperture 2. The edges of the slot 24 in the contact have a self-cleaning effect on a valve pin inserted in position between the contact and the groove 12. The contact can rock against the curved or ribbed wall 11 so as to accommodate pins which are angularly misplaced. The central aperture 6 may be provided with a brass liner 30 resiliently held in place, and having an upper flange or set of lugs 34, a soldering tag, and inwardlyprojecting contact strips. The base 1 may be provided with suitable ears for securing to a radio chassis, or it may be secured by a flange 39 held against the chassis by a clamping plate 38 which also has a projection 44 engaging one of a series of notches 43 in the base to prevent rotation.

Title: Improvements in or relating to means for the admission of the charge to the cylinders of two-stroke cycle internal combustion engines
IPC: F02B75/02
Filed: 1944-07-14
Abstract: 580,631. Two-stroke engines. FISHER, R. J. July 14, 1944, No. 13476. [Classes 7 (ii) and 7 (vi)] In a two-stroke engine in which a precompressed charge from the crank chamber or a precompression pump enters the cylinder through an admission port arranged in the piston head and controlled by a valve 15 which is free to move between its seat and an abutment 19, subject solely to the pressure difference on its two sides, except for the inertia force of the valve itself, means is provided which exerts an axial thrust in opposition to this inertia force when the piston is near the bottom of its stroke. This means may comprise a light spring 20 or pivoted levers connected to a counter-balancing weight mounted in the piston. A conical surface 21 on the piston approaches closely the cylinder head 22 and restricts the combustion chamber to a chamber surrounded by a conical surface 12 which also guides the entering charge. This charge may be whirled by helical vanes radiating from, and supporting, a boss 17 which guides the valve stem. The valve may alternatively comprise a flat plate which may be a disc, or annular, and is guided on helical ribs extending from the conical surface 12. Stops may comprise studs in the piston head or a split ring accommodated in the groove. As shown in Fig. 1, the invention is applied to an engine having crank case compression, but the charge may be compressed outside the crankcase delivered through registered ports in the cylinder and piston and a chamber in the piston. In a further modification, Fig. 6, the valve 35 is annular and surrounds a conical boss 34 on the piston and has a conical seating therewith. It may extend to the width of the cylinder bore and is counterbalanced by a weight 38, acting through levers 40.

Title: Improvements in or relating to machines for ornamenting boots or shoes
IPC: A43D93/00
Filed: 1933-05-10
Abstract: 419,363. Boot-making machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., and KEALL, F. B., Belgrave Road, Leicester. May 10, 1933, Nos. 13554 and 30895. [Class 17 (i).] Ornamenting.-In a machine for indenting shoe sole margins by a toothed wheel co-operating with a sole support, the wheel is mechanically driven and also reciprocated transversely of its axis to impart a beating action to the sole margin, and the support is maintained in position to resist such action by a device possessing considerable inertia and acting under gravitation. The work support 10 is freely rotatable and mounted adjustably for tilt on an arcuate member 12 held in an arm 14 pivoted at 16. The member 12 rests on a plunger 22 vertically adjustable in a guided sleeve 28 linked to an arm 38 pivoted on a boss 40, itself pivoted eccentrically at 43 to the machine column and having an arm 44 on which is slidably adjustable a weight 46, the arm normally resting on a stop 50. A treadle rod 54 is pivoted to the arm 38. Depression of the treadle straightens the toggle constituted by the link 34 and its connection with the arm 38 and raises the arm 44 so that the support presses the sole against the indenting wheel with a substantially constant pressure while moving in response to variations in sole thickness. The indenting wheel is driven through a clutch 68 from a spur wheel 62 and also reciprocated towards and from the work by an eccentric portion 19 of a driven shaft 80. A spherical bearing surface 74 connects the indenting wheel with the part 19, and the bearings for the shaft 60 are tapered and cut away at top and bottom, respectively, to allow the transverse reciprocation. In a modification, the shank of the indenting wheel is carried by a bearing reciprocated in a vertical slide, and the shank is connected to its driving shaft by a coupling comprising splines and co-operating grooves arranged at right - angles in disc members. A gas pipe 67 is provided for heating the tool. Guide fingers 21 arranged on the two sides of the wheel prevent damage to the shoe upper. The shaft 80 is driven at some 2000 revolutions per minute and the wheel at about 40. The vertical travel is about 02 inch with a wheel having sixteen teeth to the inch, less teeth necessitating a greater travel. According to the first Provisional Specification, the sole support may be pivoted near the central pivot of a lever having a 30 lb. weight at one end and one of 18 lbs. at the other.
