Title: Machine for manufacturing tubular or tube-like articles from strip or like metal
IPC: B21D5/01
Filed: 1925-06-25
Abstract: 254,504. Setten & Durward, Ltd., and Setten, R. S. June 25, 1925. Fastenings; penholders; pipes. - In a machine for making small metal tubes, paper clips, penholders, &c. from strip metal, a blank is positioned on a U- shaped die and is first bent into U-form by a mandrel carried by a plunger, and is then closed by a punch carried by a second plunger situated above and cooperating with the die and mandrel. The metal strip e is fed intermittently in a direction at right-angles to the power shaft c over a blanking die d, by grippers e<3>, e<5>, which engage the scrap strip and are mounted on a slide e<2> reciprocated by a cam-operated lever g. The gripper e<5> is adjustably mounted on a lever e<4> which is pressed down to effect the feed by a peg e<7> on a cam-operated slide f. A blank is punched out of the strip by a punch h carried by an eccentrically-operated slide h<2> and is received on the set edge of a bending die j which is mounted on a slide i traversed from a position below the blanking die to a position below the co-operating bending members l, m by a lever k<2> operated by a cam k. The blanking punch carries a pressure plate h<7> which is normally held by a spring h<13> against an adjustable abutment h<9> on a cam-operated slide h<10>. Passing through the sides of the die clear of the operative portion are four pegs j<4> mounted on a stem j<5> which travels with the slide i and is connected at j<6> to a slotted arm j<7> rigidly carried by an extension j<8> of the slide f. When the blank is punched from the strip the plate h<7> and pegs move towards each other to grip the blank and the blank is then lowered thereby on to the die j. The slide i is then moved to a position under a mandrel l mounted on a cam-operated plunger l<2> which is moved down to bend the blank into U-form whereupon a die m carried by a cam-operated slide m<2> moves down to bend the blank into tubular form. A cam-operated plunger l<9> cooperates with the free end of the mandrel l to assist the action thereof. The slide i carries a stripper lever y' which is pressed by a spring y<5> against an adjustable stop and which wipes over the tube when the slide moves towards the die d after the punch m and mandrel l have been raised, but which engages the inner end of the tube and thus ejects it during movement of the slide in the other direction. Letters &c. may be impressed on the strip between the blanking die and punch. In making penholders the strip may be provided with nib-grip perforations or extensions before the blank is cut and the perforations &c. may be additionally shaped after stripping from the mandrel.

Abstract: 947,336. Hydraulic shock-absorbers. ARMSTRONG PATENTS CO. Ltd. April 26, 1962 [May 6, 1961], No. 16529/61. Heading F2S. A vane-type hydraulic damper, for use in a vehicle steering assembly, comprises a rockable shaft 12 which is journalled in a body member 10 and carries a radial vane 22 which works in an hydraulic chamber 14 and co-operates with a fixed abutment 24 mounted within, to divide, the chamber 14 into two compartments 26, 28 communicating with a valve chamber 44 through passages 46, 48, and a relief passage 82 leading from the bearing clearance around the shaft 12 to a reservoir 84. The passage 46 leads into the upper end of the valve chamber 44 which threadedly receives, in its outer end, an axially-bored plug 50 having a peripheral groove 52 which registers with the passage 48. The plug 50 is counterbored at 56 to provide a seat 58 for a spring-loaded hollow valve 60 the end of which within the counterbore 56, is formed as a seat for a second spring-loaded valve member 68. Oblique passages 70 connect the counterbore 56 with the peripheral groove 52 the springs 62, 66 being adjusted to offer equal resistance to hydraulic flow in either direction. The valve seats 58, 64 are radially notched in order to provide a limited rate of hydraulic flow before the valve members 60, 68 lift from their seats. When high hydraulic pressure is generated in the compartment 26 or 28 fluid can escape around the spindle 12 and through the relief passage 82 to the reservoir 84 which is vented to atmosphere excessive high pressure on a spindle end seal 80 being avoided. To prevent cavitation effects due to loss of fluid from the chamber 14 recuperation valves 86 are accommodated in recesses 88 which are formed in the abutment 24 and communicate with the hydraulic compartments 26, 28. Each recuperative valve comprises a valve ball 90 closed by a spring against a seat formed in a passage 92 which is formed in an end plate 16 separating the chamber 14 from the reservoir 84 and which communicates with the reservoir 84. Sealing sections 32, 34 are slidingly received in slightly deeper recesses, 36, 38 which are provided in the outer end of the vane 22 and which communicate respectively with the compartments 26, 28 through parts 40, 42.

Patent GB-201534-A (GB)
Title: Improvements in or relating to front wheel brakes for motor vehicles
IPC: B60T11/04
Filed: 1923-06-27
Abstract: 201,534. Soc. Anon. des Etablissements Ballot. July 26, 1922. Transmitting-mechanism.-Relates to a cam, chiefly applicable to the control of the segments of front wheel vehicle brakes, of the type which is mounted in an apertured sleeve which actuates the brake segments on rotation of the cam, the cam 1 being carried by the vehicle frame whilst the sleeve 4 having a square-sectioned aperture 5 is secured to the stub axle of the wheel. The cam is constructed from a cube or parallelopiped, the top and bottom faces being formed by the intersection of two cones 6, 7, the cone 6 being generated by rotation of the faces 8, 11 of the aperture 5 when the faces 9, 10 are parallel to the pivoting axis CD, whilst the cone 7 is generated by rotation of the same faces when the faces 9, 10 are inclined to the axis CD, which forms the geometric axis for the cones. The lateral operative faces of the cam are formed by the intersection of a cylinder 12 and a cone 13, the cylinder being generated by the rotation of the faces 9, 10 about CD when the sleeve is in the non- braking position before wear of the brake segments has taken place, whilst the cone is generated by the rotation of these faces about CD when the sleeve has been rotated to take up wear and the faces 9, 10 have become displaced relative to the pivoting axis. With this construction, the cam is capable of pivotal movement round the axis CD without appreciable play between it and the sleeve both when the faces 9, 10 are parallel to the axis and when they are displaced with respect to it, whilst rotation of the cam about the axis AB applies the brake. The lateral surfaces 13 may comprise portions of a number of cones, or be constituted by the envelope of the cones generated by the faces 9, 10 for all positions of the sleeve between that shown in full lines, and that shown in dotted lines in Fig. 1; in the latter case the top and bottom faces of the cam are formed as spherical caps.
