Abstract
Abstract A mounting base for the movement of a gauge such as a pressure or vacuum gauge, which comprises a plastic unitary bracket wherein a shaft bearing has a slotted wall through which a pinion shaft or other shaft of the movement can be inserted and retained. Side projections also can be mounted on both sides of the bracket, each side projection having an aperture and slot into which selectively can be inserted the arbor shaft or pinion shaft of the movement. The arbor shaft can be inserted into either side projection so that the indicator gauge can function as a pressure or vacuum gauge. The slot is narrower than the bearing aperture so that the shaft can be snapped or pushed therethrough into the bearing hole and retained therein.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
96 words
In an indicator gauge or the like having a pinion, segment and arbor movement, the combination including a unitary plastic material movement bracket, shaft bearing means in said bracket for said movement, said bearing means including large and small pairs of apertures with a wall having slot means therein, movement shaft means mounted in the larger of said bearing means apertures, said slot means being dimensioned whereby said shaft means can be moved therethrough into the smaller of said bearing means apertures and will be retained therein, and condition responsive means connected to said shaft means.
Claim 2
Dependent Claim
96 words
In an indicator gauge or the like having a pinion, segment and arbor movement, the combination including a unitary plastic material movement bracket, shaft bearing means in said bracket for said movement, said bearing means including large and small pairs of apertures with a wall having slot means therein, movement shaft means mounted in the larger of said bearing means apertures, said slot means being dimensioned whereby said shaft means can be moved therethrough into the smaller of said bearing means apertures and will be retained therein, and condition responsive means connected to said shaft means.
Claim 3
Dependent Claim
52 words
In an indicator gauge or the like as claimed in claim 1 wherein there are at least two shaft means, one having a pinion thereon and connectable to an indicator, the other having a sector gear thereon meshing with said pinion, and means connecting said sector gear to said condition responsive means.
Claim 4
Dependent Claim
53 words
In an indicator gauge or the like as claimed in claim 2 wherein the slots and walls of the apertures are so positioned that tendency of the shaft means to separate during operation will urge the shafts against surfaces of the bearing means away from the slots so as to provide bearing support.
Claim 5
Dependent Claim
32 words
In an indicator gauge or the like as claimed in claim 2 wherein said pinion shaft has a hairspring thereon and said bracket has means for receiving one end of said hairspring.
Claim 6
Dependent Claim
27 words
In an indicator gauge or the like as claimed in claim 4 wherein said bracket has slot means for receiving and holding said end of said hairsprIng.
Claim 7
Dependent Claim
43 words
In an indicator gauge or the like as claimed in claim 1, said movement mounting base having a plurality of bearing means for selectively receiving said shaft means whereby the mounting base can selectively be used for vacuum and pressure condition responsive actuation.
Claim 8
Dependent Claim
30 words
In an indicator gauge or the like as claimed in claim 2 wherein the bearing means selectively interchangeably receive said shaft means for vacuum and pressure actuated condition responsive means.
Claim 9
Dependent Claim
50 words
In an indicator gauge or the like as claimed in claim 7 wherein there are at least one center bearing means and bearing means on each side thereof whereby the center bearing means and one of the bearing means on the side can be used to support the shaft means.
