Patent GB-729401-A (GB)
Title: Improvements in or relating to electric control apparatus for multi-speed transmission gears
IPC: F16H61/32
Filed: 1953-08-11
Abstract: 729,401. Controlling change-speed gearing. BOSCH GES., R. Aug. 11, 1953 [Aug. 13, 1952], No. 22080/63. Addition to 727,757. Class 80 (2). [Also in Group XXXVII] A modification of the electric switching apparatus described in Specification 727,757 relates to the control of a reversible electric motor 10 having oppositely-wound field windings 11, 12 and driving a control shaft for actuating the gear-changing mechanism of a vehicle. The control gear for the motor comprises an electromagnetic switch 14, an impulse switch 15, and a switching device 16 having cams 25, 26, driven by the control shaft. In order to change from the neutral position shown into first gear, the switch 74 is momentarily engaged with contact 73, the contact 44 being closed when the driver occupies his seat. A coil 69 of the switch 15 is thus energized to close contacts 76, 63, and current passes from battery 18 through holdcoil 71 and operating winding 22 of switch 14. Energization of the motor 10 through its field winding 12 follows, and the cams 25, 26 are driven in a clockwise direction. After movement through a predetermined angle, a camoperated switch 36 is closed so that current flows directly to the winding 22 and the hold-coil 71 is short-circuited (with normal operation), the springs 65 returning the switch 15 to its neutral position. Rotation of the cam 25, 26, through a further angle causes a projection 46 to open switch 53 for a short period so interrupting the circuit of coil 71 and opening switch 15 in the event of imperfect short-circuiting due to soiling of the contacts of switch 36. The switch 14 remains closed until projection 29 opens switch 36 to disconnect winding 22 and stop the motor in the position of engagement of the first gear. A change without interruption to the sixth gear may be effected by continuous engagement of the contact 73, and, when the last gear is reached, the switch 53 is opened by projection 51 to prevent further rotation in the clockwise direction. Changing down to a lower gear is effected by engaging switch 74 with contact 72, the joint use of a switch 79 being necessary for changing from neutral to reverse gear. A motor-driven arm 77 is used to light signal lamps for indicating the engagement of the various gears.

Apparatus for measuring or indicating variations in the diameter of a cylindrical test surface G along the length thereof, comprises a guide B, a carriage C mounted for movement along the guide, a pair of oppositely directed feelers F, F<SP>1</SP> carried by such carriage for engagement with diametrically opposite points of the test surface throughout traversing, at least one of the feelers F<SP>1</SP>being mounted for movement relative to the carriage in a plane through the axis of the test surface, whereby the distance between the tips of the feelers varies with the diameter of the test surface along the length thereof detecting means F<SP>2</SP>, F<SP>3</SP> responsive to said variations for operating a measuring or indicating instrument, and testing means L, L<SP>1</SP> operable at will for imparting a reciprocating motion to the carriage, in a direction transverse to the direction of traversing and to the line between the feelers, to test that the feelers will, when the testing means is rendered inoperative, engage the test surface throughout traversing at diametrically opposite points on such surfaces. The workpiece G is mounted Fig. 2 (not shown) on an adjustable 'V'- block support so that its axis is parallel with the guide shaft B. Depending on whether the internal or external diameters is being measured, the feelers are mounted on a bar E<SP>4</SP> Figs. 5, 6 (not shown) or arms E<SP>2</SP>, E<SP>3</SP> respectively. In the embodiment shown in Fig. 3 the feeler F is an abutment feeler and the feeler F<SP>1</SP> a measuring feeler. The testing means comprises two pairs of angularly spaced supports K together with an arm L and cam L<SP>1</SP> for pivotally rocking the supports about a horizontal axis so that the carriage and therefore the feelers are reciprocated across the test surface. The testing means is operated during traversing and the position of the workpiece is adjusted according to the trace of a pen recorder connected through amplifying means to the feelers. If the feelers are not in contact with the workpiece on the ends of a diameter, the waveform will have the same frequency as the reciprocation but if the workpiece is correctly positioned the frequency of the trace will be doubled. In an alternative testing means Fig. 7 (not shown) a supplementary guide shaft P is reciprocated to move the carriage C and the guide shaft B is fixed to the casing. With this arrangement both feelers are flexibly mounted and they lie in a plane normal to the bisecting plane of the carriage support.

Title: Brake assembly with an automatically adjustable brake unit
IPC: F16D65/60
Filed: 1971-04-19
Abstract: 1345361 Brake adjusters WESTINGHOUSE BREMSEN-UND APPARATEBAU GmbH 19 April 1971 [21 Feb 1970] 22303/71 Addition to 1152960 Heading F2E An automatically adjustable brake unit of the worm and worm-wheel type is characterized in that the shaft 6 of the worm 5 is coupled via a uni-directional coupling 10 with a lever 21 formed by two ports 22, 23 mounted on a coupling ring 8 of the coupling 10 and clamped together, which lever 21 has two stop surfaces 33, 34 which are co-operable with stops 30, 31 formed on a stop member 29 secured to a vehicle port. A brake lever 2 is actuable to cause rotation of a brake cam-shaft 1 on which is mounted the worm-wheel 4, but no relative movement of the worm 5 and worm-wheel 4 occurs and the shaft 6, coupling 10 and lever 21 are swung with the brake lever 2 about the axis of the cam-shaft 1. If the distance of swing of the brake lever 2 exceeds a predetermined value as a result of wear in the brake linings the lever 21 will bear against the stop 31 through stop surface 34 and the lever 21 and the coupling ring 8 firmly connected thereto by a clamp connection 28 will be turned about the axis of the worm shaft 6, the coupling 10 including clamping elements 9 which allow rotation of the lever 21 in this direction. When the brake is released the brake lever 2 swings back and the coupling 10 acts so that the worm shaft 6 is driven and the brake lever 2 on the camshaft 1 is also turned to a certain extent corresponding to the wear on the brake lining. A friction brake 35 prevents unintentional displacement of the brake lever 2. If it is necessary to increase the brake clearance, e.g. after lining the brake, the clamping connection 28 is released by loosening the clamping screws 24, 25, and the worm shaft 6 is turned back by means of a suitable tool fitted to an actuating head 19. In the embodiment of Figs. 4-6, there are three clamping screws 124, 125, 145 which extend through arcuate slots 146, 147, 148 in one part 122 of the lever 121 and are screwed into the other port 123 of the lever 121. By loosinging the screws the distance between the two stop surfaces 133, 134 may be altered.

Title: Improvements in self-locking nails
IPC: F16B13/04
Filed: 1952-09-05
Abstract: 735,646. Nails. ELASTIC STOP NUT CORPORATION. Sept. 5, 1952 [Sept. 15, 1951], No. 22357/52. Class 89(2). [Also in Group XXII] Nails, e.g. those for securing shingles &c. to artificial wall boards of fibrous material or of gypsum &c., and having two adjacent shanks connected by a collapsable head permitting relative movement between the shanks to cause lateral deflection of the less rigid shank to give the necessary holding power, have the more rigid driving shank also weakened at a point intermediate its ends so that, should the point encounter one of the frame members of the building the head portion may continue to be driven without further advance of the point. The nails, that may be made from thin stainless steel strip, have the point of the holding shank 14, Fig. 1, of V-shape, the metal removed from the V forming the point 12 of the driving shank, thus reducing the overall length of the stock required. The holding shank has a comparatively wide punched-up tongue 30 and the driving shank a narrower tongue 26 on the headside of which is a narrow slot 28. Slits 20, 24 at the edges of the shank facilitate the bending of the head from the shank and notches 18 facilitate collapse of the head. The shanks are bent to V-channel section and nest, as shown in Fig. 7, the holding shank being flattened at the edges 34a from the tongue 30 to the point. In the driving position the tongues 26, 30 interengage and when the underside of the head contacts the shingle the holding shank is arrested and further penetration of the driving shank bends the holding shank laterally, as shown in Fig.8, during the flattening of the head. Should, however, the driving point encounter a frame member rendering further penetration difficult, the metal at the sides of the slot 28 collapses, forming wings 28a that provide the holding power. Specification 605,164 is referred to.
