Title: Improvements relating to change speed operating mechanism for motor cycles and the like
IPC: B62M25/04
Filed: 1930-11-07
Abstract: 363,778. Controlling variable-speed gearing. HARRIS, J. C., 20, Amesbury Road, Moseley, Birmingham. Nov. 7, 1930, No. 33483. [Class 80 (ii).] In order to impart stepped angular displacements in either direction to a spindle A, Fig. 1, controlling the change-speed gear of a motor cycle, repeated oscillations are imparted to a pedal N, Fig. 5. The pedal N is secured to a cover-plate M loose on the spindle A, and is struck by the foot to effect the required movement. A peg L fast in the plate M passes to the left of Fig. 1 through a notch J, Fig. 4, in a pawl plate G, then through a gap X, Fig. 3, in a stop plate E, then over a fixed angled stop C<1> between two springs D<1>, D<2>, Fig. 2, supported in a fixed casing B. Stop plate E, Fig. 3A, carries a through peg F on one end Fl of which is pivoted the pawl plate G which can rock to bring either of its pawl teeth H<1>, H<2>, Fig. 4, into engagement with a ratchet wheel K. Fig. 3, which it embraces. Ratchet wheel K is fast on spindle A. The other end of peg F projects over a fixed angled stop C<2>, Fig. 2, between two fixed return springs D3, D4. When the pedal N is moved up or down, the cover-plate M turns so that the peg L carries pawl plate G with it without at first moving the stop plate E. Plate G rocks far enough to engage one or other of the pawl teeth H<1>, H<2> with the ratchet wheel K. The plates M, G, and E, ratchet wheel K, and spindle A are then locked together and are carried along with the pedal until one of two stop pegs S<1>, S2, Fig. 3, on the plate E engages and is stopped at R, R<1>, Fig. 2. Spindle A has completed one step in the gear change, and is locked by suitable means so that on release of the pedal N, the springs DI and D<4> or D<2> and D3 return the other parts to the initial position. Spindle A may be moved a step farther, or a step back, by a further oscillation of the pedal. An indicator P, Fig. 1, fast to the spindle A moves over the fixed casing B to show what gear is connected at any time. The spindle A may be moved directly at any time by an independent hand-lever Q.

Abstract: 462,567. Magnetos. WICO ELECTRIC CO. Dec. 13, 1935, No. 34687. Convention date, Jan. 17. [Class 35] The shaft 36 of a magneto is supported in needle bearings 41 in a fixed sleeve 22; the rotor surrounds the sleeve at a short distance, flanges 35 at the end of the rotor being secured to a flange 37 on the shaft by screws 38. The sleeve 22 is secured by casting to a hub on the end wall 21 of the casing. The rotor and shaft can be withdrawn through an opening 16 in the other end wall 17, which opening is normally closed by a cup-shaped member 53 secured by screws 55 and surrounding the driving- member 51 of an impulse coupling, a felt washer 62 enclosed between discs 57, 60 being interposed between the two. The diameter of the bearings 41 is more than half the diameter of the bore of the rotor and the length of the "needles" in the bearings is several times their diameter. The flange 37 abuts on the end of the sleeve 22 to form a thrust bearing. The rotor consists of two bar magnets 31, Fig. 11, and laminated pole pieces 30 held together by cast metal 32 entering dovetail slots in the polepieces. To hold the magnet and polepieces in position during casting brass plates 30<1> held together by rivets 31<1> are provided; these are covered by the casting-metal. The armature consists of two laminated polepieces 24, Fig. 8, fixed in the side wall of the casing and bridged by a laminated body 25 which carries the windings 64, 65. The casing is closed by an insulating cover 18 and has at one corner a cylindrical recess to receive the condenser 67, Fig. 10, which has at its lower end a spring jaw terminal 68 by which it is grounded on the casing and at its upper end a screw terminal 70. The upper end of the condenser is secured to the casing by an insulating block 71 and screws 73. Lubricant is supplied to a pad 113 and is conveyed thence by a disc 115 on the shaft 36, a scraper 116 and a passage 118 in the sleeve 22 to the bearings 41 ; then it passes between the sleeve 22 and the flange 37 and is discharged by a ring 34 on the rotor into a channel 119 whence it returns to the pad 113.

Title: Improvements in or relating to resilient mountings

IPC: F16F1/38
Filed: 1957-11-12
Abstract: 860,241. Resilient mountings. METALASTIK Ltd. Oct. 21, 1958 [Nov. 12, 1957], No. 35295/57. Class 108(3). In a resilient mounting a bush 3 is bonded to inner and outer sleeves 1 and 2. During the bonding process the rubber bush shrinks and is in tension after the process. To eliminate this tension the bush is precompressed by expanding the inner sleeve radially over its entire length. This expansion is brought about by forcing a conical drift through the sleeve 1 in the direction of the arrow 6. During this operation the ends of the rubber bush which are in the immediate vicinity of the sleeve 1 move axially towards each other. The inner sleeve 1 may be frusto-conical in shape and arranged substantially parallel with the outer sleeve 2.

Title: Methods of manufacture of conductor rails

Filed: 1972-07-28
Abstract: 1395178 Making conductor rails SWISS ALUMINIUM Ltd 28 July 1972 [29 July 1971 (3)] 35435/72 Heading B3A [Also in Division B7] A method of making a conductor rail 10 comprising a body of aluminium or aluminium alloy, on which is a layer 19 of wear resistant material extending over the whole length of the body, includes applying the layer 19 while in liquid condition, at least where it engages the body, and dissipating nearly all its heat content through the body. The layer 19, which is preferably of steel, but may be of nickel or chromium or copper alloy, is cast around sides 13, 14, 15 or a combination of these sides, depending on the type of pick-up 18 to be used. Flame spraying, spray welding or plasma spraying may also be used. The intense localized heating effect of the last method allows for rapid removal of heat by the remainder of the rail while bonding occurs between the body and the layer before the destroyed aluminium oxide reforms. The layer 19 may be a pre-formed band, which is heated to a liquid state on one side and then pressed or rolled on to the body. Cooling devices may be fitted to the body of the rail to assist in heat dissipation. To prevent diffusion between the body and layer 19 an intermediate layer 20 may be applied, which layer is of nickel, nickel-aluminium, or tin, zinc, silver, copper or alloys of these metals. The intermediate layer may be applied by plasma spraying to form a porous layer providing for the retention of lubricant and water repellant materials which may be applied at the same time as the layer 19. The lubricant is graphite or molybdenum disulphide and the water repellant is a silicon compound. Alternatively PTFE may be used, which serves both as lubricant and water repellant, as it soaks into the pores of the layer 19.

Title: Improvements in or relating to thermally controlled delayed action electric switches

Filed: 1938-12-06
Abstract: 510,658. Electrically released switches. MANNHEIMER, G. Dec. 6, 1938, No. 35489. Convention date, Jan. 15. [Class 38 (v)] A switch with delayed action, such as may be used in staircase lighting, is held closed against a spring by a thermally controlled catch which releases a movable part step-by-step to open the switch, the catch meanwhile first rotating in one direction about an axis in one direction, and then about a second axis in the other direction. A button 3 is pressed down and held against a spring by a catch 11 which is pivoted at one end of a thermal element 13 and is pulled by a spring 15 across two lugs 5 and 6. In this position a heating coil 24 of the thermal element 13 is closed by the engagement of contacts 17, 18 of which 17 is electrically connected with a contact 20 which bridges contacts 21, 22 and closes the circuit to a load 25. The thermal element 13 then bends about a fixed support 14 into the position shown in Fig. 5 causing the catch 11 to pivot about an edge 9 on the lug 6 until it is free from the top edge 7 of the lug 5. The button 3 then springs up until an edge 10 made by cutting a step in the lug 6 engages the catch 11, and the heating circuit 24 is broken although the main circuit still remains closed. The thermal element now cools and causes the catch 11 to rotate about an edge 8 on the lug 5 until the lug 6 is released and the push button moves up to open the main circuit. The heating up time is short compared with the cooling time which can be adjusted by rotating the support 14.
