Abstract
Abstract An improved component for a switching device for operating a plurality of switch means sequentially such as taught in U.S. Pat. No. 3,701,962. The operators of each of the switch means are engaged by a ''''T'''' shaped wobble plate at spaced positions around the arms of the plate. A thermal operator comprising a heated bimetal has an output member for engaging at or near the center of the ''''T'''' wobble plate to apply a force on the plate and thus a force on each of the switch operators depending upon distance between the output member and the switch operator. The ''''T'''' wobble plate is made of two elongated bimetal sheet members fastened together to form a ''''T'''' configuration and has the effect of warping upon changes in temperature to provide ambient temperature compensation for the switching device.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
150 words
In an improved switching device of the type having one or more switch means each having an operator to which a force is applied to operate said switch means, having thermal operator means having an output member for providing a force when said operator means is energized, and having bimetal ambient temperature responsive means connecting the output member of said thermal operator means to said switch means operators for applying a force to each of said operators for operating said switch means in sequence; the improvement residing in the ambient temperature responsive means and comprising: T-shaped bimetal ambient temperature responsive means comprising two elongated rectangular strips of bimetal rigidly fastened together in the form of a T whereby said force of said output member of said operator means is applied at a point of contact between the points of contact on said T of said operators of said switch means.
Claim 2
Dependent Claim
150 words
In an improved switching device of the type having one or more switch means each having an operator to which a force is applied to operate said switch means, having thermal operator means having an output member for providing a force when said operator means is energized, and having bimetal ambient temperature responsive means connecting the output member of said thermal operator means to said switch means operators for applying a force to each of said operators for operating said switch means in sequence; the improvement residing in the ambient temperature responsive means and comprising: T-shaped bimetal ambient temperature responsive means comprising two elongated rectangular strips of bimetal rigidly fastened together in the form of a T whereby said force of said output member of said operator means is applied at a point of contact between the points of contact on said T of said operators of said switch means.
Claim 3
Dependent Claim
45 words
The invention according to claim 1 in which said T-means is cupped to impart to said switch means operators a force having a horizontal component as well as a vertical component, the horizontal component of force urging the switch means operators in a predetermined direction.
Claim 4
Dependent Claim
47 words
The invention according to claim 1 in which the contact surface of said T-means with said switch means operators is angled with respect to said switch means operators to impart to said switch means operators a force having a horizontal component as well as a vertical component.
Claim 5
Dependent Claim
128 words
An improved T shaped temperature responsive wobble plate means for a sequential switching device comprising: three switch means each having an operator to which force is applied to operate said switch means, said operators being spaced triangularly; operating means for providing a force on an output member; T-shaped temperature responsive wobble plate means connecting said operating means and said switch means, said T shaped means comprising two elongated rectangular strips of bimetal rigidly fastened together in the form of a T and being responsive to ambient temperature wherein extremities of said T wobble plate means engages said operators and said output member applies a force to a central portion of said plate means to be distributed to said operators for operating said switch means in a selected sequence.
Claim 6
Dependent Claim
128 words
An improved T shaped temperature responsive wobble plate means for a sequential switching device comprising: three switch means each having an operator to which force is applied to operate said switch means, said operators being spaced triangularly; operating means for providing a force on an output member; T-shaped temperature responsive wobble plate means connecting said operating means and said switch means, said T shaped means comprising two elongated rectangular strips of bimetal rigidly fastened together in the form of a T and being responsive to ambient temperature wherein extremities of said T wobble plate means engages said operators and said output member applies a force to a central portion of said plate means to be distributed to said operators for operating said switch means in a selected sequence.
