Title: Improvements in or relating to vehicle brakes
IPC: F16D65/09
Filed: 1934-05-24
Abstract: 436,902. Brakes. BENDIX, Ltd., and HALL, P. E., King's Road, Tyseley, Birming- ham. May 24, 1934, Nos. 15496 and 31583. [Class 103 (i)] In a two-shoe self-energizing brake the thrust is transmitted from the primary to the secondary shoe by a lever h which is adapted to fulcrum about either of its ends according to the direction of rotation of the brake drum. The lever is arranged between the ends of the shoes remote from the cam. The shoes reverse their functions as primary and secondary and the lever h fulcrums about its opposite end when the direction of rotation of the brake is reversed. The lever h is adapted to pivot on a fulcrum g or g<1> on a block e which is pivotally mounted at f on the back plate and held against rotation by the adjusting means t. The shoes engage the lever h by plungers k, m. The leverage ratio of the thrust transmitted from one shoe to the other is the same in both directions of rotation but may be moved by spacing the recesses l, n at different distances from the ends of the lever. Block e is adjusted by the conical head t of a screwed member, working between inclined surfaces on the block and a fixed member q. The conical head may have flats engaging the inclined surfaces and according to Provisional Specification 31583 /34 the conical head may have longitudinal serrations or flats engaging a ball catch on one of the inclined surfaces. The screwed member is mounted in a pivoted link or allowed limited movement in a slot on the back plate to allow for its necessary movement during adjustment. Plungers m, k may be in two parts screwed together for adjustment purposes and according to Provisional Specification 15496 /34 the outer screwed parts of the plungers may have gear teeth, which mesh with a common operating pinion.

Patent GB-351683-A (GB)
Title: Improvements in automatic continuous gearing devices
IPC: F16H61/662
Filed: 1930-05-22
Abstract: 351,683. Variable-speed gearing. TORULF, H. G., 11, Blasieholmstorg, Stockholm. May 22, 1930, No. 15811. Convention date, June 4, 1929. [Class 80 (ii).] Variable-speed friction gearing comprises a pair of rollers 15, 16, Fig. 1, which are moved simultaneously across a disc 14 by a governor 37, Fig. 6, so as to drive the disc 14 and driven shaft 31 at a speed suitable to the load and to the speed of driving-shaft 1. The shaft 1 is rotarily connected to a gear 79 which drives gears 20, 21 fast on the shafts 22, 23 upon which the rollers 15, 16 are splined. The disc 14 is connected to shaft 31 through a sleeve 26 and slipping plate clutch 29. Gear train 74, Fig. 1, is for reversed driving which is attained by opening clutch 29 and applying a brake to planet-carrier 78. The figure shows the direct-drive position when the rollers 15, 16 have been approached sufficiently to thrust out a loose wheel 34 and so thrust direct-driving clutch 57, 59 into action. The disengaging-spring 58 of this clutch supplies for geared drives the initial pressure of the disc 14 on the rollers 15, 16. During geared drives, this frictional pressure is increased proportionally to torque by a cam presser device 7, 8, Fig. 4. Cam 7 is fast on shaft 1 and cam 8 on a sleeve 9 which through ball bearing 11 and members 12, 13 communicates the thrust to disc 14. The rollers 15, 16 are operated in unison by forks 45, 46, Fig. 6, screwed on threads of opposite hand on a control shaft 41. Loose gears 64, 48 are driven in opposite directions from gears 44, 50 on the rollers. The governor 37, which is revolved by gear 48, operates a double clutch 42 splined to the shaft 41 so as to clutch shaft 41 to gears 64, 48 alternatively to move the rollers 15, 16 in one direction or the other along their shafts, and so vary the speed. The fork 46 at the ends of its travel strikes tappets 68, 70, which disconnect the governor from screw shaft 41. The speed range is varied by stressing governor spring 53 from control lever 54. The rollers approaching their inner terminal position bring in the direct clutch drive automatically by striking wheel 34, Fig. 1.

Filed: 1968-04-02
Abstract: 1,152,816. Rotary mowers. FLYMO S.A. 2 April, 1968, No. 15896/68. Heading A1F. An electrically driven rotary mower comprising housing 1, wheels 3, cutter disc 9 and vertical power drive shaft 8 is characterized in that two electric motors 14, 15 which are similar in every respect and whose axes are horizontal, are mounted symmetrically with the respect to the drive shaft 8. Each motor shaft is fitted with a bevel gear 12, 13 drivingly engaged with a common bevel gear 11 non rotatably mounted on the drive shaft 8. The housings of the motors 14, 15 are rigidly connected to a sleeve 4 that is supported by struts 5 to housing 1, the sleeve containing bearings 6 and 7 that journal the drive shaft 8. An air impeller 10 rigidly mounted on the drive shaft draws air from an aperture in housing 1 and expells it under rim 2. The air current prevents accumulation of grass clippings in housing 1 and may provide an air cushion supporting the mower. The two electric motors are of the series-wound type and are connected to the power source through a flexible cable and a switch (not shown) which may couple the two motors in series during starting and later switch them in parallel to the source of electric current. Both the wheels and the cutter are adjustable.

Abstract: 1,067,586. Photo-electric detection of marks. EASTMAN KODAK CO. April 17, 1964 [April 24, 1983], No. 15948/64. Heading G1A. In an arrangement for the detection of marks on the surface of a web, the web 11, (Fig. 2) is conveyed past the detection area over a rotatable roller 10, the light from a source 20, mounted in an opaque housing 26 passing through a window 18 in an opaque plate 34 on to the web and being reflected from it to a photo-cell 24. The opaque housing 26 is supported by subplate 28 attached to a fixed plate 17 and the roller shaft 16 supported by ball races 14 in a sleeve 15 secured to the plate 17. The roller itself is driven by the web. Guide shoes 35, 36 having arcuate inner surfaces, cover the ends of the roller 10 and have blackened surfaces to prevent escape of light through the very small gaps which are necessarily provided to prevent frictional contact between the guide  shoes and the roller, and between the web and the plate 34. The web passes into the detector arrangement from a small roller (40) Fig. 1 (not shown) which is also mounted on the support plate 17. This is adjustable in position in order to make major adjustments In the length of paper between a fixed roller (45) and the processing equipment which is downstream of the detector arrangement. Fine adjustments are made by  moving the detector arrangement itself circumferentially about the axis of the roller shaft 16, this being allowed by the loosening of nuts 46. The system has application in the production of roll film in which the film has a backing paper, on which there are frame indexing numbers etc.

Abstract: 160,157. Universelle Cigarettenmaschinen-Fabrik, J. C. M³ller & Co. March 6, 1920, [Convention date]. Cigarette mouthpiecemaking machines.-Relates to machines for winding paper strips or blanks into spirals which are inserted later in the ends of cigarettes. The rotary winding needle f carries a projecting tappet finger k acted on by a roller n on a bell-crank lever l to rotate the needle within the sheath a and grip the paper blank between the needle and sheath at the beginning of the winding operation. A sheath carrier b, mounted in a bearing c, is rotated by a pinion d, toothed segment e, lever t, and cam v to wind the paper blank on the sleeve. The needle is then rotated in a reverse direction within the sheath, to release the rolled paper spiral, by the other roller n of the lever l, which is operated by a cam r. A spring g within the carrier b bears against a collar k fixed on the needle f and presses the collar i on the end of the needle into frictional contact with the end of the carrier to cause the needle and sheath to move together.
