Title: Improvements in or relating to cutting tools
IPC: B23C5/24
Filed: 1942-04-27
Abstract: 553,627. Milling, boring and like cutters. BENNINGHOFF, W. L. April 27, 1942, No. 5650. Convention date, April 21, 1941. [Class 83 (iii)] Cutting tools such as milling-cutters, boring- tools, reamers, or threadcutting tools have inserted cutting blades each mounted in a body slot 5 and supported on an inclined lower surface 5b and one side surface 5a, the other side surface being serrated for engagement by clamping wedges, one of which has a single tooth engageable with a selected serration on the blade. In the application to an end-mill or boring-tool the body 1 has blades 2 which are adjusted along their slots to obtain simultaneous radial and axial blade adjustment. The rear side of each blade is plane and engages the plane wall 5a and the front of each blade has parallel serrations 2a of uniform depth. The blades are clamped by one or more wedges moved inwardly by right- and left-hand screws 10 screwed into the body and into the wedges. The latter are preferably part-cylindrical in form and the wedging surface is provided with a single tooth 6a coacting with a groove in the holder. Spaced from the tooth 6a, the wedge also has a shallow inclined surface 6b and a more steeply inclined surface 6c, these surfaces having a line of separation 6d engaging the grooved tops of the blade. If in tightening the wedge the tooth 6a and the zone 6d do not engage the grooves simultaneously slight rotation of the wedge on its axis may occur thus ensuring secure clamping of the blade without the necessity of high accuracy in machining the grooves on the cutter. The cutter is also free to move end-wise slightly during the tightening action to accommodate itself to the position of the wedge tooth. For short blades only one clamping wedge may be used for each blade but for long blades, as shown, a second wedge 9 is employed. This may be similar to the wedge 6 but preferably it is formed without a toothengaging a blade groove and has a contact zone 9c, Fig. 8, between differently inclined surfaces 9a, 9b.

Title: Improvements in the dyeing of leather
IPC: D06P3/32
Filed: 1936-02-25
Abstract: Mordant dyes, dyeing with.--In dyeing leather, especially glove leather and shoe uppers, upon one side only, a fixing agent for the dye is first applied to that side only, a solution of the dye is then applied to the same side only by brushing, spraying or the like and a fixing agent is applied to the dyed surface.  A suitable fixing agent is (a) a solution in methanol of formic, acetic, lactic, oxalic, citric, tartaric, maleic, malic or phosphoric acid or (b) an aqueous solution of basic chromium sulphate and cream of tartar.  The skins are preliminarily tanned, e.g. by a formaldehyde or chrome process, fat-liquored, hung up to dry, dampened, put on a staking machine to stretch and loosen the damp fibres, and wetted out, e.g. with soap or a sulphonated oil. For the application of the fixing and dye liquors by brushing or spraying, each skin may be mounted upon a convex spherical surface to allow the liquors to drain off the edges when squeezed out by "slicking."

Title: Improvements in machines for bending and shaping sheet materials
IPC: B21D5/04
Filed: 1957-02-25
Abstract: 830,278. Angular bending; shearing. STOTT, N. May 23, 1958 [Feb. 25, 1957; June 13, 1957], Nos. 6165/57 and 18608/57. Class 83 (4). A hand-operated bending machine comprises fixed and movable jaws and a bending beam bolted at each end to a mounting assembly consisting of a deep U-shaped stirrup housing a pivot element equal in diameter to the inner diameter of the stirrup and having an outwardlyprojecting smaller portion rotatably mounted on the fixed jaw. Within each stirrup 3 is a similar oppositelydisposed stirrup 5 housing a cylindrical block 6 in which one end of a rod 7 is secured. In operation a blank is held between the jaws 15a and 15b and bent by a rotary movement of the beam 1. Alternatively the blank may be held on to the beam by a clamping plate. The bevelled beam 1 may be replaced by a composite beam comprising two unbevelled layers, Fig. 17. A stopplate 12 on a support bracket 5 limits the forward movement of the bending beam 1 in conjunction with a stop-screw 11 mounted on the stirrup 3. The movement of the bending beam in large machines is assisted by a chain 33 and sprocket 32, 34 mechanism, Fig. 7, at each end of the machine the axis of the sprocket 34 being eccentric to that of the beam and thereby progressively increasing the torque on the beam as the driving sprocket 32 is rotated by a handle 36. To resist the machine stresses adjustable pillars 39 support the front beam 41 and eccentric bushes 43 carried by a rear beam 26 support a front tool while beam clamps 44 counteract the stresses tending to push the front jaw forwards. As shown in Fig. 6, a clamping-plate 20 co-operates with a complemental plate 21 on the movable jaw of a vice to bend a blank 19 to U-shape. In a modification, Fig. 10, the beam 1 is held in a vertical position and carries the back-plate 47 of a brake press assembly in which a forming tool 50 is mounted in a recess in a sliding plate 49 and lugs 55a mounted on the rotatable rod 7 engage rotatable rollers 54 on the sliding plate and depress it to form a sheet blank on a complementary tool 58 held between the machine jaws. In another modification a cutter blade 70 is mounted on the beam 1 and cooperates with fixed cutter bars 71 which may be held horizontally or vertically in a vice. Specifications 541,479, 567,943 and 779,755 are referred to.

IPC: B01D25/02
Filed: 1957-02-25
Abstract: 821,967. Filters. BRITISH FILTERS Ltd. Jan. 31, 1958 [Feb. 25, 1957], No. 6251/57. Class 46. In Fig. 2 a filter sheet supporting plate consists of an annular piece of metal gauze or mesh 1 bounded at its edges by U-sectioned borders 2, 3. One only of the borders is cut away to provide openings 4 leading to the wire mesh. The plate constitutes an " inlet " supporting plate. In Fig. 3 (not shown) the inner border is thus cut away, providing an " outlet " supporting plate. The supporting plates are assembled alternately with intervening layers of filter material 6, Fig. 5, on a perforated tube 7 so that unfiltered liquid (e.g. servo oil) flows into openings 4 of " inlet " supporting plates, spreads over the meshes 1, and thereafter passes axially through the adjacent filter sheets to the " outlet " supporting plates, whence it flows into the tube 7. The assembly is constrained between apertured end plates 9, 10 serving as inlet plates. In Fig. 8 a flat ring 16 is joined by radial portions (not shown) to a further flat ring 18 on one face, and on the opposite face a flat ring 19 is joined by radial portions (not shown) to a U-sectioned ring 20 joined at 21 to the ring 18 on the first face, the plate thus constituting an inlet plate with a continuous inlet slot Fig. 10 (not shown) shows a similarly constructed outlet plate. The filter sheets (preferably of paper) are in groups each numbering, e.g. four sheets of increasing fineness, the coarsest sheet being located next to an " inlet " supporting plate. Felt or porous plastic filtering material may be used.
