Abstract: A material processing apparatus comprising a body, and a conveyor that is movable between a deployed state and a transport state. The conveyor comprises a feed end, a discharge end and conveying means configured to carry material from the feed end to the discharge end. The discharge end is coupled to the body and, in the deployed state, the conveyor extends from the body with the feed end being spaced apart from the body by the conveying means. In the transport state, the conveyor is folded with respect to the body.

Abstract: An assembly method and a thermostat for an electric/gas oven are provided. An enclosure formed by a base and a cover for enclosing a switch subassembly includes axially aligned channels extending through opposed walls and external keying and positioning features. A pair of axially aligned actuators are received within the axially aligned channels. A frame having cooperating keying and positioning features positions and supports the enclosure containing the switch subassembly and supports both a temperature responsive subassembly and a spindle subassembly in operative position with respect to the actuators. The spindle subassembly includes a cam member mounted on a spindle for rotation with the spindle. The cam member provides a cam surface having a first cam rise equivalent in a first range of rotation of the spindle and a second cam rise equivalent in a second range of rotation of the spindle.

Abstract: A thermostat for use with an oven of an electric or gas range includes a first electrical contact terminal, a second electrical contact terminal and an actuating assembly including an actuating spring arm for opening and closing an electrical path between the first and second contact terminals. The spring arm has a fixed end mechanically and electrically coupled to the first electrical contact terminal by a movable support member and a free end that moves between a contacting position and a noncontacting position with the second electrical contact terminal. The manually operable mechanism is movable to an OFF position and to a plurality of ON positions for selecting an oven operating temperature. The temperature responsive mechanism is movable in response to changes in oven temperature. A positive-off mechanism maintains the noncontacting position of the spring arm responsive to the manually operated mechanism moved to the OFF position.

Abstract: A thermostatic switch assembly with a diaphragm responsive to pressure generated in a fluid filled temperature sensing bulb-and-capillary. The diaphragm contacts and moves a pivoted lever having a beam spring cantilevered beam spring adjustably mounted thereon. Movement of the lower about its pivot causes the beam spring to effect actuation of a switch. Upon loss of fluid in the bulb and capillary, the diaphragm recedes and a stop remote from the lower pivot functions as an auxiliary pivot for the beam spring for effecting emergency switch actuations.

Abstract: A contact mechanism for a temperature switch using a thermally expandable member wherein a plate making a circular arc motion is provided at a tip of a piston which is moved by the thermal expansion member, and a coil spring is mounted between a middle of a movable member having a fulcrum in an almost center of the plate and a stationary end of a terminal. The movable member is reversibly mounted. The plate is moved by the motion of the piston. When a point of power of the movable member is shifted, the movable contact is shifted instantly to the stationary contact side, and the movable contact slides on the stationary contact by the motion of the piston. The coil spring doubles as the return spring.

Abstract: A control device adapted to select a set-point temperature for a condition responsive device. The control device has temperature selecting means rotatable through a preselected temperature range generally between a pair of opposite rotated positions, and resilient means is disposed for engagement with a part of the temperature selecting means upon rotation thereof in response to a rotative applied force from one of the opposite rotated positions toward the other thereof so as to arrest the rotation of the temperature selecting means in a predetermined rotated position between the opposite rotated positions. Means is movable in response to another applied force thereon for driving the resilient means toward a displaced position disengaged from the part of the temperature selecting means, and the temperature selecting means is thereafter further rotatable upon further exertion of the rotative applied force thereon from the predetermined rotated position toward the other opposite rotated position.

Abstract: A thermally actuated switch including a motive member which is adapted to move one contact either toward or away from its opposed mating contact in response to an increase or decrease in pressure in a fluid actuating heat sensing system, the fluid system translating temperature into fluid pressure. The assembly further includes a hydraulically actuated high temperature switch which is adapted to be rendered responsive to a preselected temperature, as for example, 550.degree. to 600.degree., the switch being utilized to control an external circuit, as for example, the deactivation of a door lock solenoid. The switch assembly includes two fixed contacts, the positions of which are fixed in response to the position of a cam element. A pair of mating movable contacts are controlled by a temperature responsive assembly, which temperature responsive assembly reacts in response to the sensed temperature of an oven.
