Title: Improvements in and relating to gear finishing
IPC: B23F19/06
Filed: 1947-08-26
Abstract: 655,672. Gear - cutting. NATIONAL BROACH & MACHINE CO. Aug. 26, 1947, No. 23556. Convention date, Sept. 3, 1946. [Class 83 (iii)] A method of shaving a gear comprises meshing the gear and tool with their axes crossed at an angle of 3 to 20 degrees, and effecting one or more relative traversing strokes in a plane parallel to the axes and at an angle between 5 and 65 degrees to the tool axis, while maintaining the spacing of the axes unchanged. At the end of a traverse, the tool and gear pass into loose mesh and the direction of rotation may be reversed before the return stroke is made. The grooves in the cutterteeth are not less than about 0.03 inches wide and are roughly equal to the width of the lands. The cutting-edges lie in parallel planes. The traversing of the cutting-planes through the point of crossed-axes results in a slight undulating effect on the surface-finish which, however, is improved by the burnishing action of the lands. The quality of surface-finish obtainable is fully discussed. Modifications of a few thousandths of an inch may be made in the cutter-teeth 50, Fig. 3, or 60, Fig. 4, in order to impart reverse modifications, e.g. crowning, to the gear-teeth. The direction of traverse is chosen so that a particular section of a geartooth is machined by the required section of the cutter-teeth. Specifications 480,247, 514,530 and 618,220 are referred to.

Title: Improvements in or relating to boot or shoe heel trimming machines
IPC: A43D87/00
Filed: 1926-09-30
Abstract: 282,889. British United Shoe Machinery Co., Ltd., Gouldbourn, J., and Woodcock, R. B. Sept. 30, 1926. Trimming. - A machine for trimming the top lifts of Louis or like heels has a tread rest and a support for the heel sides movable into and out of operative position, and means whereby when the support is moved the angle between the rest and the cutting edge is automatically changed, so that the breast edge can be trimmed to a different angle from that at the back and sides. A rotary cutter is provided, and a guide member comprising parts respectively tangential to and concentric with the cutter, capable of being presented alternatively at the operating position, for use when the breast and the remainder, respectively, is being trimmed. This guide can be swung out of the way to permit removal of the cutter. A toothed cutter 6 is held by an expanding sleeve 7, Fig. 4, on the end of a rotating shaft 5. A shaft 37, Figs. 1 to 3, toothed to engage a pinion operated by a handle 38 is thus adjustable parallel to the cutter axis and carries a plate 36. Lugs on this plate carry a shaft 16 on which is pivoted the tread rest 39. The shaft 16 also carries a bell-crank lever 17 operating a fork engaging a groove in a sleeve 10 rotating with but slidable along the shaft 5 and carrying a bevelling cutter 9 the teeth of which intermesh with those of the cutter 6. A guide 22 engages the part of the heel adjacent to the top lift, and is provided with a concentric portion 23, for use when the sides and rear of the top-lift are being trimmed, and a tangential portion 24, for use for the breast edge. The guide is fixed to a stud 25 slightly out of line with the axis of the cutter, so that the guide is nearest the cutter at the operating point-adjacent to the tread rest. The stud is supported by a bracket 26, provided with a latch 28 for holding the guide in either of its operative positions, and carried on a stern 27 urged rearwardly by a spring against an adjustable stop. The guide is adjustable about the stem 27 by a screw 31. By pulling the bracket forwardly, the guide can be swung away from the cutter to permit removal of the latter. To the tread rest is pivoted an arm 42 carrying an adjustable roller 45 for supporting the heel when the sides and rear are being trimmed. This arm moves with a block 46 adapted to engage one of two screws 49, 50 carried by the plate 36, the effect being that the angle between the rest and cutting edge is varied by swinging the roll 45 into inoperative position, when the breast edge is to he trimmed. The block has a cam surface for engaging the stop screw and forcing the tread rest to its appropriate position when the roll 45 is returned to operative position. The guide 22 may be circular, and may rotate as the work is fed. For operating on low shoes the arm 42 may be removed and a work supporting roll may be mounted on a stud secured in one of a series of holes in the tread rest.

The leaves are moved by half-nuts K, K<1> which work in grooves in a shaft L having an internal thread. A shaft R engaging this thread carries a third leaf S with a wire T stretched across the opening in it to mark off the desired area, the movement of the leaf S being such that the area marked off by the wire T is a constant fraction of the total area of the opening of the leaves H<1>, H<2>. In place of the wire a strip of transparent tinted material may be used. Specification 365,330 is referred to.

Title: Improvements in or relating to springs

Abstract: 519,524. Torsion springs. DOBLHOFF, W. Aug. 19, 1938, No. 24513. Convention date, Aug. 26, 1937. [Class 108 (iii)] Bar springs are held in radial slots in connecting rings, the slots being closed at their outer ends. As shown in Fig. 3, bars 1 arranged about an axis 2 are held in brackets in a mounting 6 and are oscillated by a lever arm 7 attached to the central portion of the bars. The bars 1, Fig. 1, are fixed in radial 'slots in end and centre rings 8 by inner rings 10 expanded by conical bolts 11 and prevented from moving longitudinally by pegs 13 or rings 15. A tube 25 may be attached 'to the central ring 8 and overlap the end rings to prevent excessive bending of the bars. The bars may be secured in the radial slots by wedges or where two bars are housed in the same slot a radial wedge may be driven between the bars. In Fig. 10 the bars are secured by slotting the metal between two radial slots and driving a conical pin 20 in the slot 19 to expand the metal against the sides of the bars. The metal between the slots for the bars may be extended between the bars and reduced in thickness to form an abutment against which the ,springs bear in a progressive manner under load. The seating surface of the bars in the slots may be bevelled or recessed so that the ratio of the stresses set up in the bars by bending and torsion may be varied. In order to obtain a uniform stress in the bars the depth of the bar may be reduced at h<2>, Fig. 1, or the thickness or if the bar springs are of round cross-section the effect may be obtained by changing the diameter or by flattening the cross-section. The ends of the bars may be secured to the holders 8 by filling the spaces between the bars and slots with a pressed or cast and hardening or solidifying mass 31, Fig. 13, such as artificial resin, metallic alloys &c. The material is poured into a two part 'mould 35 having a shaped end plate and a cover 38 with inlet orifice 39. A plug 40 is inserted in the bar-spacing bush' 32 and a head 41 which may be integral with the plug 40 is used to guide the material around the bars. According to the Specification as open to inspection under Sect. 91, the bars are formed integrally with the holders. This subjectmatter does not appear in the Specification as accepted.
