Abstract
An electrical brush contact for use in an electrical circuit requiring the conduction of electrical energy between relatively moving objects, said contact having a contactor block mounted on one of said objects and a block engaging brush mounted on the other object, said brush providing a stud disposed adjacent to the path of relative movement of the block, a helical spring mounted on the stud having an anchored end and an opposite end, and a plurality of wire bristles mounted on said opposite end of the spring and substantially tangentially extended therefrom for block engagement.
Claims5
A brush contact comprising a pin, a helical spring mounted in circumscribing relation on the pin and having opposite ends, means mounting one end of the spring in fixed relation to the pin, and brush means mounted on the opposite end of the spring and extended transversely from the pin substantially tangentially of the helical spring.
In a system having an electrical circuit for use on a vehicle having a wheel rotatably mounted thereon with a portion of the circuit and a contactor mounted on the wheel, and the remainder of the circuit mounted non-rotatably on the vehicle, a brush contact adapted to make intermittent contact with the contactor as the wheel rotates so as to connect rotating and non-rotating components of the circuit comprising a pin mounted on the vehicle adjacent to the wheel, a helical spring mounted in circumscribing relation on the pin having one end anchored on the vehicle and an opposite free end, and a brush of bristles mounted on the free end of the spring and extended substantially tangentially of the spring into the path of travel of the contactor during wheel rotation.
In a tire pressure sensing apparatus for use on a vehicle having a wheel rotatably mounted on the vehicle with a contactor mounted on said wheel wherein the sensing device includes an electrical circuit having some components on the rotating wheel and non-rotating components elsewhere on the vehicle;
- an electrical brush contact adapted to make intermittent contact with the contactor including a plurality of elongated electrically conductive wire bristles disposed in substantially normal relation to the plane of the wheel;
- a clamp securing together a common end of the bristles;
- a mounting bracket mounted on said vehicle in spaced relationship to said wheel;
- a pin disposed on said mounting bracket in substantially parallel relation to the plane of the wheel;
- a spring circumscribing the pin with one end connected to and supporting the clamp and the other end connected to the non-rotating components disposed to enable the wire bristles to engage the contactor when opposite thereto;
- and a stop borne by the mounting bracket whereby the contactor makes periodic contact with the bristles as the wheel rotates, the spring allowing the bristles to be pivoted in the direction of the contactor motion and the stop serving to limit spring motion in the opposite direction.
