Patent number: 4732243Abstract: An automatic adjuster for a vehicle brake actuator has a non-rotatable brake shoe-engaging tappet, an adjuster member having a threaded shank threadedly engaged with a nut, the adjuster member co-acting with the tappet so that said rotation of the adjuster member causes axial movement of the tappet. The adjuster member is drivingly coupled by a coupling member to a shaft having an external reversible thread and a spring acting between the tappet and shaft urges the tappet against the shoe. A clutch ring has an internal reversible thread whereby it engages the corresponding thread on the shaft and is resiliently urged towards a fixed clutch face. The clutch ring controls rotation of the adjuster member during brake actuation and release to adjust the retracted position of the tappet to compensate for wear of the brake shoe.Type: GrantFiled: November 6, 1986Date of Patent: March 22, 1988Assignee: Lucas Industries, Public Limited CompanyInventors: Brian Ingram, Hugh G. Margetts, John R. Rees

Patent number: 4702354Abstract: A hydraulic actuator for a vehicle brake incorporates an automatic adjuster which includes a strut of variable length formed by members which are threadedly interengaged by way of non-reversible screw thread connection. The member is an adjuster shaft which forms a reversible screw thread connection with a drive ring arranged to control rotation of the adjuster shaft during brake application and release. The non-reversible thread is subject, during brake application, to an axial force which is the resultant of forces derived from the braking pressure applied to different areas defined respectively by a seal on the piston and a further seal on the adjuster shaft. This ensures that random rotation of the adjuster shaft during brake application is resisted without the necessity for the application of axial spring load.Type: GrantFiled: February 2, 1987Date of Patent: October 27, 1987Assignee: Lucas IndustriesInventors: Brian Ingram, Hugh G. Margetts, John R. Rees

Patent number: 4702352Abstract: An automatic adjuster includes a two part strut interconnected by a non-reversible thread so that extension of the strut under the influence of an adjuster device is effected by relative rotation between the two parts. The adjuster device includes a spigot, rotation of which is controlled by a clutch member as a result of a cooperation between helical teeth respectively on the strut part and spigot and also uni-directionally couples the spigot to a fixed member so that in the event of temporary clutch disengagement due to vibration, rotation of the spigot in the de-adjusting direction is prevented by rotation thereof is the adjusting direction is permitted when required.Type: GrantFiled: March 20, 1986Date of Patent: October 27, 1987Assignee: Lucas Industries Public Limited Co.Inventors: Brian Ingram, Hugh G. Margetts, Michael J. England

Patent number: 4535875Abstract: An actuator for a shoe drum brake has a body containing a tappet engaging one of a pair of brake shoes, and a split tappet of which the outermost piston engages the other brake shoe. A mechanical wedge actuator acts between the tappets for emergency and parking operation. The piston cooperates with an automatic adjuster of which a component normally engages an abutment member which bears against a shoulder within the body to isolate the adjuster from the piston of the split tappet and thereby from the other tappet.Type: GrantFiled: March 3, 1983Date of Patent: August 20, 1985Assignee: Lucas Industries, Public Limited CompanyInventors: Brian Ingram, Michael J. England

Patent number: 4380277Abstract: An automatic slack adjuster comprises a pair of thrust assemblies. Each thrust assembly acts between a cam and a respective shoe-end and is guided to slide axially in a bore in a housing. Each thrust assembly comprises a nut which engages with, and is held against rotation with respect to, a respective shoe-end, and a screw-threaded tappet having a piston part which slides in the bore, and an integral threaded stem of reduced diameter which is screwed through the nut. The piston parts are both provided with gear teeth to enable them to be rotated together by the engagement of a crown wheel, or a pair of pinions carried by opposite ends of a transverse shaft which is rotatable in a bore normal to a bore in which the cam shaft carrying the cam is rotatable.Type: GrantFiled: October 9, 1980Date of Patent: April 19, 1983Assignee: Lucas Industries LimitedInventors: Brian Ingram, David A. Harries, Michael J. England

Patent number: 4350230Abstract: A drum brake is disclosed in which at least two, and preferably four, friction pad assemblies are symmetrically arranged with respect to the drum. The pad assemblies are slidably guided for movement towards and away from the drum in a substantially radial direction on drag-taking abutments in a relatively stationary drag-taking member, and the pad assemblies are applied to the drum by levers upon which actuators act.Type: GrantFiled: September 4, 1980Date of Patent: September 21, 1982Assignee: Girling LimitedInventors: Brian Ingram, David A. Harries, Ramamurthy Natarajan

Patent number: 3979153Abstract: A booster operated master cylinder piston for use in an anti-skid braking system includes a modulator piston located between the master cylinder piston and the booster valve assembly. In the event of a skid the pressure of booster fluid acting on the modulator piston is relieved.Type: GrantFiled: August 5, 1975Date of Patent: September 7, 1976Assignee: Girling LimitedInventors: Brian Ingram, David Anthony Harries

Patent number: 3954305Abstract: An actuator assembly for a vehicle brake includes three axially aligned pistons, a first actuating piston for applying the brake hydraulically during normal service braking; a modulator piston movable for anti-skid purposes between a first position in which an inlet valve controlling the supply of fluid to the first actuating piston is open, and a second position in which the inlet valve is closed; and a second actuating piston resiliently urged through the modulator piston to engage the first actuating piston to apply the brake for parking purposes but normally held out of engagement by fluid pressure in a chamber formed between the modulator piston and the second actuating piston, the pressure in the chamber also holding the modulator piston in the first position.Type: GrantFiled: September 10, 1973Date of Patent: May 4, 1976Assignee: Girling LimitedInventors: Brian Ingram, David Anthony Harries

Patent number: 3937524Abstract: In an anti-skid pneumatic braking system for vehicles a brake is applied by air from a first reservoir and the braking effort modulated by air from a second reservoir. The brake is connected to the second reservoir through two normally closed diaphragm valves in series, the first valve opened by air supplied to the brake from the first reservoir when the brake is applied and the second valve opened by air supplied from the second reservoir in skid conditions. Additionally a third normally closed diaphragm valve can be connected across the diaphragm of the brake actuator and is opened in skid conditions.Type: GrantFiled: December 8, 1972Date of Patent: February 10, 1976Assignee: Girling LimitedInventors: Brian Ingram, Henry Jamieson Riddoch

Patent number: RE28890Abstract: In an actuator assembly for an hydraulic braking system the effective volume of a chamber through which hydraulic fluid under pressure is supplied to a wheel brake is adapted to be varied between a minimum and a maximum value by movement of a piston assembly working in a bore in communication with the chamber. An actuator piston having first and second different faces of different areas normally holds the piston assembly in a position in which the effective volume of the chamber is at a minimum until equal hydraulic pressures are applied to the areas of the actuator piston to cause the actuator piston to retract and permit the piston assembly to be withdrawn whereby the effective volume of the chamber is increased.Type: GrantFiled: January 15, 1974Date of Patent: July 6, 1976Assignee: Girling LimitedInventors: Brian Ingram, David Anthony Harries, Lancelot Phoenix
