[Also in Groups XVIII and XIX] The ink ribbon 18, Figs. 1 and 2, of the recording mechanism of an instrument for checking the rate of a time-piece movement (see Group XVIII) is alternately wound off and on one of two reels 19, 20 connected respectively to pinions 21, 22 alternately driven by a gear 23, 24.

A second rocker comprising two levers 28 is pivoted at 27 to the rocker 25 and supports a roller 29 urged by a spring 30 against the reel 19 or 20 receiving the ribbon. When the diameter of said reel reaches a predetermined maximum the spring 30 pulls the roller 29 on to the other reel by a toggle action and weight of the roller 29 rocks the rocker 25 so that the pinion 21 or 22 of the other reel is brought into mesh with its driving gear 23 or 24.

Title: Improvements relating to hydraulically controlled variable speed gearing
IPC: F16H59/06
Filed: 1934-03-14
Abstract: 439,799. Controlling variable-speed gearing. HAYES, F. A., Middletown, New Jersey, U.S.A., and CLOUDSLEY ENGINEERING CO., Ltd., 13, Queen Anne's Gate, London. March 14, 1934, No. 8062. Addition to 254,341, [Class 80 (ii)]. [Class 80 (ii)] The variable-speed torus-disc gearing described in the parent Specification is modified by the provision in the pressure fluid control system of a leak valve for the pressure fluid and a control handle for the said valve and a stop for the said handle adjustable according to climatic conditions to compensate for changes in viscosity due to temperature. Such a fluid control system is described in Specification 398,582, the leak valve therefor being shown at 11 and at 19 in Figs. 1 and 6 respectively of that Specification. Oil is circulated by a pump driven proportionally to engine speed under pressure subject to leakage past the leak valve, not shown, which is connected through a sleeve 3 and head-piece 4, Fig. 1, to a handle 9, to be adjusted thereby. Adjustment is effected by turning the handle 9 against a stop 12, Fig. 2. The stop 12 is formed on a ring 5, Fig. 3, adjustable according to the weather by turning it relatively to through bolts 6 connecting a cap 2<1> to a head 2 on a tubular stem 1, Fig. 1, forming the steering column of a vehicle. The ring 5 may have three positions corresponding to cold, medium, and hot weather respectively. When the handle 9 and therefore the sleeve 3 are moved angularly about the axis of the steering column, the handle will eventually come against the shoulder 12, which therefore limits the angular displacement in that direction unless the operator deliberately rocks the handle about a pivot pin 8 by depression of the handle against the resistance of a spring 10, and thereby carries a toe piece 11 on the handle clear of the shoulder 12, whereupon the angular adjustment of the handle 9 and sleeve 3 may be continued. To indicate the extent of adjustment of the leak valve, the handle 9 may be formed at its base as a knife edge pointer 9<1>, Fig. 2, moving over a scale 2<1> on the head piece 2. The other handle 15 shown, through a dished plate 13 and sleeve 14 may control the movement of the sleeve 5 of the Specification referred to, which sleeve 5 fixes the upper limit to the speed ratio reached by servo action of the oil which has been pumped and then caused to build up in pressure by the leak valve.

Slipping of wheels, preventing. - To prevent lateral skidding and to act as a brake, runners, skids, or rollers are pressed by the driver into contact with the road. A frame 3, 4, Fig. 1, hinged at the rear of the vehicle is operated by a special lever 8 through relay or other mechanism or by a connection to the brake lever and carries a roller 6 which is thereby pressed downwards, the return or lifting movement being effected by a spring. The roller may consist of rubber or other discs 9, Fig. 5, and intermediate, pieces 10. Clearing teeth 12 on a bow 11 mounted on the frame 4 may be provided. A rotary cleaning brush 15, Fig. 7, may engage the roller and may be driven in the reverse direction by gearing.

Abstract: 674,214. Hydraulic shockabsorbers. MONROE AUTO EQUIPMENT CO. April 3, 1950 [June 30, 1949], No. 8330/50. Class 108(iii) The piston of a direct-acting hydraulic shock absorber comprises axially-spaced piston parts 22, 23 each having passage means 24, 24' which permit free flow between a space 41 and the cylinder spaces on either side of the piston, on movement of the piston in opposite directions, each piston part 22, 23 also having additional passage means 36, 45 permanently open at their outer ends, and a respectivepressure responsive valve means 50, 39 at their inner ends which constitute the sole means for respectively controlling the flow through the additional passage means 45, 36 on compression and rebound strokes respectively, at all operating and velocity conditions. The body portions 22, 23 are mounted on a reduced end 19 of the piston rod 18 and are spaced by the valve means 39, 51 (which are in the form of laminated disc valves), and a spacer 43. The portions 22, 23 are clamped between respective washers 29, 35 by a nut 20 and a piston-rod shoulder 21. Each washer 29, 35 retains a respective sealing ring 25, 33 which permits liquid flow between its periphery and the cylinder wall, in one direction and prevents it in the reverse direction. The periphery of each piston portion 22, 23 is fluted at 24, 24<SP>1</SP>.The passage-means 36, 45 are in the form of circumferentially-spaced, axially-extending ports in the respective piston portions 22, 23. The uppermost lamination of the valve 39 has a series of peripheral slots 44 to provide a bleed action. The valve 50 has similar bleed slots. The shock absorber has a base valve assembly of the kind described in Specification 481,935 comprising a laminated compression valve and a spring-loaded replenishment valve. In operation, on compression, liquid is unable to pass between the periphery of the seal 33 and is forced upwardly through ports 45 to lift the valve 50. It then passes freely through the fluted peripheral portions 24 of the piston portion 21 and around the periphery of the seal 25 to the cylinder space above the piston. The compression valve is designed so as to open at the same time or prior to the opening of the valve 50. On rebound, liquid above the piston passes through the ports 36 to lift the valve 39 and around the periphery of the piston portion 23. Liquid flows freely through the replenishment valve into the cylinder from the reservoir.
