Abstract
Abstract A belt-tension gauge for measuring the tension of a belt spanning a pair of wheels, especially a V-belt in the engine compartment of a motor vehicle, comprises two pivotally interconnected housing parts which are biased by a spring spread apart and carry respective rollers which bear upon one side of the belt while a member at the pivot rests against the opposite side. The relative displacement of the two housing parts by the spring is displayed by indicia on one of the housing parts and indicates belt tension.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
132 words
A belt-tension gauge comprising: a housing formed by a pair of housing parts pivotally connected for relative swinging movement about a pivot axis; means forming a rotary bearing between said housing parts at said pivot axis; a pressure member mounted on the means forming said bearing and adapted to engage one side of a belt whose tension is to be measured; a respective backing member on each of said housing parts adapted to engage an opposite side of said belt; spring means in said housing for urging said housing parts in opposite senses about said axis whereby said backing members are displayed away from each other; and a scale on said housing for indicating the degree of relative displacement of said parts by said spring thereby displaying the tension in said belt.
Claim 2
Dependent Claim
132 words
A belt-tension gauge comprising: a housing formed by a pair of housing parts pivotally connected for relative swinging movement about a pivot axis; means forming a rotary bearing between said housing parts at said pivot axis; a pressure member mounted on the means forming said bearing and adapted to engage one side of a belt whose tension is to be measured; a respective backing member on each of said housing parts adapted to engage an opposite side of said belt; spring means in said housing for urging said housing parts in opposite senses about said axis whereby said backing members are displayed away from each other; and a scale on said housing for indicating the degree of relative displacement of said parts by said spring thereby displaying the tension in said belt.
Claim 3
Dependent Claim
51 words
The gauge defined in claim 1 wherein one of said housing parts is formed of a box shape open to the other of said housing parts and can receive said other housing part substantially completely in a closed position of the gauge, said other housing part being formed with said scale.
Claim 4
Dependent Claim
23 words
The gauge defined in claim 1 wherein said spring means includes a leaf spring having a U-shaped bent portion imparting spring force thereto.
Claim 5
Dependent Claim
47 words
The gauge defined in claim 3 wherein said leaf spring is mounted in said housing with opposite ends separated against said housing parts and sides therein turned away from said axis and said U-shaped bent portion is disposed centrally of said leaf spring proximal to said axis.
Claim 6
Dependent Claim
18 words
The gauge defined in claim 1 wherein said backing members are rollers rotatable on the respective housing parts.
Claim 7
Dependent Claim
17 words
The gauge defined in claim 1 wherein said pressure member is an eccentric rotatable on said housing.
Claim 8
Dependent Claim
24 words
The gauge defined in claim 6, further comprising a spring-loaded ball indexing means for angularly indexing said eccentric in a plurality of selective positions.
Claim 9
Dependent Claim
22 words
The gauge defined in claim 6, further comprising pawl and ratchet means for indexing said eccentric in a selected angular position thereof.
Claim 10
Dependent Claim
26 words
The gauge defined in claim 8 further comprising a torsion spring between said eccentric and said housing tending to rotate said eccentric into a starting position.
Claim 11
Dependent Claim
27 words
The gauge defined in claim 1 wherein said scale is of U-section enabling the reading thereof from opposite sides of said housing and from an end thereof.
Claim 12
Dependent Claim
29 words
The gauge defined in claim 1, further comprising latch means for releasably locking said housing part in a compact position of said gauge with said housing parts nested together.
