Title: Internal air assisted brake actuator
IPC: F16D65/28
Filed: 1969-05-30
Abstract: 1,249,530. Fluid-pressure brakes. CERTAINTEED PRODUCTS CORP. 30 May, 1969 [9 Dec., 1968], No. 27577/69. Heading F2F. A brake actuator having an emergency brake applying device in which a spring is air-assisted comprises a pressure chamber divided into two compartments 23, 49 by a piston 24, an air input opening 21 and a port 50 passing through the piston to connect the compartments and containing a check-valve 52, a spring 32 being located above piston 24. Air entering compartment 23 moves piston 24 to compress the spring 32 and in these conditions the service brake works in the normal manner under the influence of air pressure in a chamber 47 acting on a flexible diaphragm 39 against a spring 44 to move a push-rod 43 and apply the brake. When air is released from chamber 23 an unbalanced pressure exists with respect to piston 24 and the pressure of air in compartment 49 assists spring 32 to act on a push-rod 30 and hence on diaphragm 39 and a pad 42 to move thrust-rod 43. Check valve 52 opens inwardly into chamber and controls the flow of air from compartment 49 to compartment 23 so that the force is great at first and then gradually diminishes as the vehicle speed decreases. Compartment 49 is charged with air from compartment 23 via an inlet valve 54 which opens at a predetermined pressure.

Title: Improvements in or relating to cam mechanisms
Inventor: HOLMAN LEONARD
IPC: G05G15/00
Filed: 1962-07-19
Abstract: 964,612. Cam mechanisms; clutches; fluid pressure brakes. AUTOMOTIVE PRODUCTS CO. Ltd. July 8, 1963 [July 19, 1962], No. 27852/62. Headings F2C, F2F and F2K. A cam mechanism, comprising a cam plate 23 having cam surfaces 25 formed thereon by pressing parts of the material thereof out of the general plane of the plate 23 and a follower in the form of balls 22, is located between a pulley 13 and a flywheel 18, the arrangement being such that on relative rotation between the pulley 13 and flywheel 18, the balls 22 ride up the cam surfaces thereby causing axial movement of the cam plate 23. Rotation of cam plate 23 relative to pulley 13 is prevented by a pin 28 projecting from the pulley and engaging a notch 29 in the cam plate. The balls 22 are housed in recesses 21 in a flange 17 of a sleeve 16 rotatably mounted on a stub shaft 15 mounted on a casing 14 secured to the pulley 13. The flywheel 18 is rotatably mounted on the sleeve 16 and a blade spring 19 provides a non-positive drive between them and is so coiled that in one direction of rotation a greater torque can be exerted to drive the flywheel than to rotate the sleeve during over-running of the flywheel, which is limited by a pin 35 on the sleeve 16 projecting into a notch 36 in the cam plate. The cam plate 23 is rotatably mounted on a headed pin 24 which is adapted to engage a plunger 30 urged into engagement therewith by a spring 31. The mechanism is applied to a sensing device in a liquid pressure braking system of a vehicle and reduces the brake applying force to prevent wheel locking. The pulley 13 is adapted to be belt driven from the vehicle transmission shaft. On heavy braking, the flywheel 18 overruns the pulley 13 and the cam plate 23 moves axially to unseat a valve closure member 32 thereby admitting air to the working chamber of a servomotor which closes a valve in the liquid pressure braking system to isolate motor cylinders, operating the brakes, from the source of pressure of the liquid pressure system, and moves a plunger to increase the volume of the isolated part of the system. Alternatively, the plunger 30 may operate an electric switch instead of a valve. In a modification, a cam plate 38 is pivoted between lugs 41 on a pulley 13, and a single cam formation 43 is engaged by a single ball.

A device for retaining a window in a position displaced parallel to the plane of the window frame comprises pairs of arms 3 and 7 at the top and bottom of the window sash pivoting at one end on an axis 4 and pivot pins 8 on a fixed frame 1. The other end of the upper arm 7 has a pin 9 which fits in a slot 10 in a plate on a cover strip 2' on a window sash 2 when the window is displaced parallel to the plane of the window frames to allow a window to be slid between the sash 2 and the fixed frame. When the window is rotated about the axis 4, the arms 3 then being secured non rotatably about the pivot pins 5 to the sash 2, the pin 9 disengages the slot 11. In modifications, the pin may be on the sash 2 and the slot on the end of the arm 7, the slot may be widened to retain the pin therein and to prevent disengagement of the slot and pin by a pull on the window, and an additional slot curved at one end may cooperate with an additional pin. To facilitate engagement and disengagement of the pin in the slot, the plate with a widened slot slides in a guide on the cover strip 2' against spring action and one edge of the slot is outwardly inclined.
