Abstract
Abstract There is disclosed a pressure gauge construction in which the dial plate includes recessed indentations interfit with pins projecting beyond the front face of the gauge movement for supporting a dial plate in place. An adhesive cement is contained between the back face of the dial plate and the front face of the movement effects an adhesive bonding therebetween.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
153 words
In a pressure gauge for monitoring values of fluid pressure comprising: a casing having an internal cavity for enclosing the operating components of the gauge and defining an exterior inlet at which fluid pressure to be monitored can be communicated through an outlet of said cavity; a pressure sensor operably displaceable in response to changes in pressure being received; a pointer indicator arcuately displaceable in response to displacement by said pressure sensor; a stationary dial plate including an aperture through which to receive a shaft for supporting said pointer indicator and localized radial recesses about said aperture at predetermined spaced locations on the back surface thereof; and a stationary support plate onto which said dial plate is permanently mounted and secured and including radial projections at locations coinciding with the predetermined spaced recess locations of said dial plate to receive the back surface of said dial plate in a secured intermitting support thereon.
Claim 2
Dependent Claim
153 words
In a pressure gauge for monitoring values of fluid pressure comprising: a casing having an internal cavity for enclosing the operating components of the gauge and defining an exterior inlet at which fluid pressure to be monitored can be communicated through an outlet of said cavity; a pressure sensor operably displaceable in response to changes in pressure being received; a pointer indicator arcuately displaceable in response to displacement by said pressure sensor; a stationary dial plate including an aperture through which to receive a shaft for supporting said pointer indicator and localized radial recesses about said aperture at predetermined spaced locations on the back surface thereof; and a stationary support plate onto which said dial plate is permanently mounted and secured and including radial projections at locations coinciding with the predetermined spaced recess locations of said dial plate to receive the back surface of said dial plate in a secured intermitting support thereon.
Claim 3
Dependent Claim
44 words
In a pressure gauge in accordance with claim 1 in which there is included a quantity of adhesive cement between the back surface of said dial plate and said support plate to effect an adhesive bonding between the support plate and the dial plate.
Claim 4
Dependent Claim
61 words
In a pressure gauge in accordance with claim 2 in which said pressure sensor comprises a diaphragm assembly, there is included a movement mechanism operatively intervening between said diaphragm assembly and said pointer and said support plate comprises a stationary plate secured to the forward end of said movement in a plane extending transverse to the axis of said pointer shaft.
Claim 5
Dependent Claim
34 words
In a pressure gauge in accordance with claim 3 in which said support plate includes parallel spaced apart and extending pins laterally forward of the face plane of said plate to comprise said projections.
Claim 6
Dependent Claim
36 words
In a pressure gauge in accordance with claim 4 in which said dial plate recesses comprise integral punch indentations extending from the backface of said dial plate to past the front face of said dial plate.
