Abstract
Abstract A bimetal type indicator comprising an insulating plate provided with a plurality of projections, a gauge section carrier plate engaged with said projection, an adjustable holding member secured to said gauge section carrier plate by means of a rivet, a pointer driving bimetal element mounted on said adjustable holding member, a pointer support member fixed to said rivet and engaged with said locating projections of the insulating plate at the side of said gauge section carrier plate opposite to said insulating plate, and a pointer rotatably mounted on said pointer support member and adapted to be angularly displaced in response to the deformation of the bimetal element.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
253 words
A bimetal type indicator comprising: an insulating plate provided with locating projection means, a gauge section carrier plate fixed to said locating projection means on said insulating plate, a pointer support means fixed to said locating projection means on said gauge section carrier plate, a pointer means having a slot formed therein and pivotally mounted on said pointer support means by means of a pin, a bimetal means having an elongated portion extending into said slot, a bimetal holding plate, on which said bimetal means is fixed, for adjusting the range of the angular motion of said pointer means, a holding plate pivotally holding said bimetal holding plate at one point and pivotally mounted on said gauge section carrier plate at the other point by means of a rivet which is coaxial with said pin, and a dial mounted on said pointer support means, and on which at least a zero point and a full range point are calibrated, wherein said slot in said pointer means extends substantially in parallel with a tangent to an arc described by said elongated part of said bimetal means when said bimetal holding plate is pivotally moved with respect to said one point, whereby said pointer means is so adjusted to be in alignment with said zero point by rotating said holding plate with respect to said rivet and thereafter said pointer means is so adjusted to be in alignment with said full range point by rotating said bimetal holding plate with respect to said one point.
Claim 2
Dependent Claim
253 words
A bimetal type indicator comprising: an insulating plate provided with locating projection means, a gauge section carrier plate fixed to said locating projection means on said insulating plate, a pointer support means fixed to said locating projection means on said gauge section carrier plate, a pointer means having a slot formed therein and pivotally mounted on said pointer support means by means of a pin, a bimetal means having an elongated portion extending into said slot, a bimetal holding plate, on which said bimetal means is fixed, for adjusting the range of the angular motion of said pointer means, a holding plate pivotally holding said bimetal holding plate at one point and pivotally mounted on said gauge section carrier plate at the other point by means of a rivet which is coaxial with said pin, and a dial mounted on said pointer support means, and on which at least a zero point and a full range point are calibrated, wherein said slot in said pointer means extends substantially in parallel with a tangent to an arc described by said elongated part of said bimetal means when said bimetal holding plate is pivotally moved with respect to said one point, whereby said pointer means is so adjusted to be in alignment with said zero point by rotating said holding plate with respect to said rivet and thereafter said pointer means is so adjusted to be in alignment with said full range point by rotating said bimetal holding plate with respect to said one point.
Claim 3
Dependent Claim
33 words
A bimetal type indicator as claimed in claim 1, wherein said locating projection means comprises a pair of projections, said guage section carrier plate having openings through which said pair of projections extend.
Claim 4
Dependent Claim
39 words
A bimetal type indicator as claimed in claim 1, wherein said dial is secured to said insulating plate by means of screw members extending through said dial and said pointer support means and screwed into said locating projection means.
Claim 5
Dependent Claim
33 words
A bimetal type indicator as claimed in claim 1, further comprising: a ground member secured to a casing of the indicator, and adapted to be electrically coupled to said gauge section carrier plate.
Claim 6
Dependent Claim
21 words
A bimetal type indicator as claimed in claim 1, further comprising: a pair of terminal lugs mounted on said insulating plate.
Claim 7
Dependent Claim
50 words
A bimetal type indicator as claimed in claim 5, wherein said terminal lugs extend from said insulating plate in a direction opposite to the direction in which said locating projection means extend, said terminal lugs having substantially rectangular heads, said insulating plate snugly receiving said heads of said terminal lugs.
