Abstract
A method of manufacturing a cradle adapted for use in a thermostat to support a plurality of switch means respectively adapted for operation at predetermined trip points. This method includes: fabricating from generally planar and thin material a plurality of cradle legs respectively having a pair of opposite end portions with at least one opening in one of the opposite end portions of at least one of the legs and at least one integral extension on at least another one of the opposite end portions of at least another one of the legs; and pivotally interconnecting the other of the opposite end portions of the legs with respect to each other and inserting the at least one integral extension means through the at least one opening.
Claims11
A method of manufacturing a cradle for use in a thermostat to support a plurality of switch means respectively adapted for operation at predetermined trip points, the method comprising the steps of:
- (a) fabricating from generally planar and thin material a plurality of cradle legs respectively having a pair of opposite end portions with an opening in at least one of the opposite end portions of at least one of the legs of the plurality thereof and at least one integral extension means on at least another one of the opposite end portions of another one of the legs of the plurality thereof;
- and
- (b) pivotally interconnecting the other of the opposite end portions with respect to each other and inserting the at least one integral extension means through the at least one opening.
A method of manufacturing a cradle adapted for use in a thermostat and having a plurality of legs with each of the legs of the plurality thereof having a pair of opposite end portions, and a plurality of switch means adapted for mounting to the legs, respectively, the method comprising the steps of:
- forming the legs from metallic sheet material;
- associating one of the opposite ends of each of the legs so that the legs are pivotally movable with respect to each other and mounting the switch means onto the legs, respectively;
- moving each of the legs one after another thereof into respective ones of adjusted positions and establishing a predetermined trip point for each of the switch means respectively mounted to the legs;
- and
- securing an integrally formed part on each of the legs in displacement preventing engagement with another integrally formed part on another one of the legs so as to prevent further movement of the legs from their respective one adjusted positions and thereby maintain the predetermined trip points of the switch means respectively mounted to the legs.
A method of manufacturing a cradle assembly adapted for use in a thermostat and including a set of legs having an intermediate portion interposed between a pair of opposite end portions, respectively, and with the intermediate portions of the legs adapted for mounting a set of mercury switches, respectively, the method comprising the steps of:
- blanking the legs from metallic sheet material and providing at least one opening in one of the opposite end portions of at least one of the legs and at least one integral extension on one of the opposite end portions of at least another of the legs;
- and
- associating the other of the opposite end portions of at least the at least one leg and the at least another leg in pivotal interconnection and overlaying relation so that the respective intermediate portions thereof are generally laterally spaced from each other and extending the at least one integral extension on the one opposite end of the at least another leg through the at least one opening in the one opposite end of the at least one leg.
