Title: Improvements in or relating to vehicle brakes
IPC: F16D51/04
Filed: 1928-02-06
Abstract: 306,269. White, A. E., (Midland Steel Products Co.). Feb. 6, 1928. Band; blocks and shoes acting on drums; compensating for wear.-In a brake wherein the friction member which engages the interior of the drum comprises a relatively rigid portion and a flexible band portion as described in Specification 263,950, the rigid portion is formed of channel section. Devices for adjusting the friction member to compensate for wear and for preventing rattling thereof are described. The friction member comprises a shoe 12 of channel section to which is secured a flexible band 9. The end of the shoe 12 and also that of a member 30 adjustably secured to the band 9 are shaped to normally engage a fixed stop pin P under the influence of a spring 61 extending between the shoe 12 and member 30 and of a second spring 62 connected to the part 12 and a fixed point 63. The expanding means comprise upper and lower pairs of toggle links T<1>, T<2> connected to vertical pins passing through horizontal pins 20, 23 pivotally mounted in the ends of the shoe 12 and the member 30 thus providing a universal connection between the links and the friction member. The joint pin 25 of the toggle is connected by a yoke to a cable which may pass through a flexible conduit as described in Specification 263,950. To permit of adjustment of the effective length of the friction member to compensate for wear, the member 30 has a part 35, Fig. 4, slidably disposed between a pair of angle members 40, 41, secured to the band 9. A guide bolt 38 passes through the members 40, 41 and a slot in the part 35 and adjustment is effected by a wedge piece 50 carried by a screw 51 and engaging corresponding surfaces formed on the members 40, 41 and the part 35. An adjustable stop for the shoe 12 comprises a member 70 having a surface eccentric to the bolt 71 by which it can be turned. The inner flange of the shoe 12 is urged by the spring 62 against an indented part of the anchor plate to prevent rattle and its axial movement is limited by the engagement of the stop 70 with the other side of the flange. Rattling of the band 9 is prevented by the engagement of a spring urged plate 81 with a bent part 80 of the band, the band being thus forced against an indented part 88 of the anchor plate. When the friction member is expanded by the toggle, the end of the band 9 is first engaged with the drum by reason of the resistance of the spring 62 and assuming the rotation of the drum to be clockwise the end of the shoe 12 remains in contact with the anchor pin P. If the rotation of the drum is in the reverse direction the end of the band is carried back to the pin P and the end of the shoe 12 leaves the pin.

Title: Improvements in cramping devices
IPC: B60B3/18
Filed: 1926-02-25
Abstract: 273,603. Gilbert, W. V. Feb. 25, 1926. Clamps.-In a hand operated tool or cramp of the kind having an eccentric as the power applying device between two relatively movable members, means are provided for pivotally connecting the two members to the eccentric sheave and to the strap or link member of the eccentric respectively. In the arrangement shown the device is employed for rotating the loose hub member which secures the removable tyre carrying portion of a road vehicle wheel of the kind set forth in Specification 273,362, [Class 144 (ii), Wheel tyres, Pneumatic &c.]. The loose hub member 13 is provided with a projecting pin 16 and the wheel 11 with a pin 10. The sheave 31 of the tool has an ecentric socket 32 engaging the pin 10 and the link 34 on the strap 33 surrounding the sheave has a socket 35 engaging the pin 16. When the handle 30 extending from the sheave 31 is actuated the pin 16 is caused to approach the pin 10, thus tightening the hub member 13. Stops 37, 38 limit the movement of the lever. The device is retained in position on the pins by a projection 39 on a quadrant 36 carried by the link 34 engaging a peripheralgroove 46 in another pin 21 on the hub member 13, the groove 46 being normally covered by a spring pressed locking sleeve 18 which is depressed when the tool is placed in position. When the tightening is completed, a notch 40 on the projection 39 comes opposite the pin 21 so that the tool may be removed. In the modification shown in Fig. 3 the notch 40 is dispensed with. The projection 39 is slidably mounted on the link 34 by means of the headed pins 51, 52 and slot 63 and is pressed outwardly by a spring 57, the device being released from the pin 21 by inward pressure of the finger piece 50.

Title: Improvements relating to electrical control networks
Inventor: RALPH FRANK
IPC: H04B3/20
Filed: 1951-02-16
Abstract: 704,465. Code telegraphy. SIEMENS BROS. & CO., Ltd. Feb. 15, 1952 [Feb. 16, 1951], No. 3851/51. Class 40 (3). [Also in Group XL(c)] An electrical gating circuit of the type in which the degree of alternation is controlled by the bias of rectifier, comprises a balanced hybrid coil. In the "on" condition the two centre tapped windings of the hybrid coil form two mutually assisting circuits which transmit the signal from the input to the output terminals and in the "off" condition the current in one half of each winding is blocked while the other halves are connected in a closed circuit which includes a resistance connected between the two centre tappings. The arrangement provides the same input and output impedances for both " on " and "off" conditions. In the Figure, voice frequency signals from source S may be transmitted via hybrid transformers TRS, TRL to the output terminals VFA, VFB, subject to control voltages applied to terminals DCA, DCB which may be double current telegraph signals. In the " on " condition, DCA is positive relative to DCB to render rectifiers EFGH conducting and MNPQ non-conducting. Signals are transmitted via two mutually assisting circuits from the secondary windings II and III of transformer TRS to the primary windings II and III of transformer TRL. The turns ratios of windings II and III to winding I are all 1/ #2 The input impedance looking into terminals CA, CB is that of the load RL (which may be a filter) and the output impedance looking into terminals VFA, VFB is that of the source S. The load and source impedances are made equal, having a value R. In the " off " condition, DCA is negative, so that rectifiers EF, GH block the signal transmission path, and rectifiers MNPQ are conducting. The upper halves of windings II and III of transformer TRS and resistance RCS form one closed circuit and the lower windings II and III of transformer TRL with resistance RCL form a second closed circuit. The value of resistances RCS, RCL is made equal to R/2 so that the input and output impedances are both equal to R, as was the case in the "on" condition. To facilitate the biasing arrangements, the value of resistances RCS and RLS may be modified in conjunction with the turns ratio of the transformers to provide the same input and output impedances.

Abstract: 918,469. Wrapping-machines. LEASURE, W. C. Feb. 9, 1960 [Feb. 1, 1960], No. 4552/60. Class 94(1). In the packaging method of the kind in which a web is drawn over a former to produce a tube, articles to be packaged being placed in the tube during its formation and the tube sealed between them by reciprocating jaws, the former is reciprocated along the tube axis, the jaws moving only normal to that axis. The tube is sealed transversely with the former in its position nearest to the jaws and while the tube is held by the latter moves away to tube the web as the contents is placed in the tube. The jaws are opened before the former changes its direction so that the tube is in effect drawn over and reverses the motion of the contents. The former then returns drawing off the web andplacing the filled tube between the jaws for sealing. In the described apparatus, the former 44 which is combined with a longitudinal seam sealer and carried on a bar 13, is vertically slideable on rods 11, 12 by chain and hydraulic piston means 16, 20-23. The jaws 24, 25 which also sever the tube, are reciprocated horizontally by linkage 29, 30, 33-36 and hydraulic pistons 27.
