Abstract
Abstract A gauge for measuring the pitch diameter of a variable speed V-belt pulley including a body member which can be engaged on the rim of the pulley, a sliding gauge bar carried by the member projecting into the groove of the pulley to engage the tapered walls of the groove of the pulley, and a scale on the gauge bar readable against indicia on the member to express the pitch diameter of the pulley.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
190 words
A gauge for measuring the widthwise deviation between the opposing walls of a tapered groove forming the rim of an adjustable V-belt pulley, comprising: a body member including means adapted to be abutably engaged with the outer edges of the walls of the groove; a gauge bar slidably mounted within said body member having an end portion of predetermined width; indicia on said gauge bar readable against corresponding indicia on said body to express the deviation of said walls as determined by the penetration depth of the gauge bar within the groove upon engagement of the end portion with the opposing walls of the groove; said gauge bar having a second end portion of a predetermined width sized to be selectively engaged in a second tapered groove of a different widthwise dimension than said first mentioned groove; and second indicia on the gauge bar readable against said indicia on the body to express the deviation of the walls of said second groove as determined by the penetration depth of the gauge bar within said groove upon engagement of the second end portion with the opposing walls of said second groove.
Claim 2
Dependent Claim
190 words
A gauge for measuring the widthwise deviation between the opposing walls of a tapered groove forming the rim of an adjustable V-belt pulley, comprising: a body member including means adapted to be abutably engaged with the outer edges of the walls of the groove; a gauge bar slidably mounted within said body member having an end portion of predetermined width; indicia on said gauge bar readable against corresponding indicia on said body to express the deviation of said walls as determined by the penetration depth of the gauge bar within the groove upon engagement of the end portion with the opposing walls of the groove; said gauge bar having a second end portion of a predetermined width sized to be selectively engaged in a second tapered groove of a different widthwise dimension than said first mentioned groove; and second indicia on the gauge bar readable against said indicia on the body to express the deviation of the walls of said second groove as determined by the penetration depth of the gauge bar within said groove upon engagement of the second end portion with the opposing walls of said second groove.
Claim 3
Dependent Claim
30 words
The invention according to claim 1, and said end portion being of a generally outwardly arcuate configuration having a radius sized to tangentially engage the opposing walls of the groove.
Claim 4
Dependent Claim
24 words
The invention according to claim 1, and said indicia on the body being spaced from said means engageable with the wall of the groove.
Claim 5
Dependent Claim
16 words
The invention according to claim 1, and said gauge being of a welded sheet metal construction.
Claim 6
Dependent Claim
14 words
The invention according to claim 1, and said gauge being formed of thermoplastic material.
Claim 7
Dependent Claim
184 words
A gauge for measuring the widthwise deviation between the opposing walls of a tapered groove forming the rim of an adjustable V-belt pulley, comprising: a body member including means adapted to be abutably engaged with the outer edges of the walls of the groove; a gauge bar slidably mounted within said body member having an end portion of predetermined width; indicia on said gauge bar readable against corresponding indicia on said body to express the deviation of said walls as determined by the penetration depth of the gauge bar within the groove upon engagement of the end portion with the opposing walls of the groove; said end portion having a predetermined breadth sized to be selectively engaged in a second tapered groove of a different widthwise dimension than said first mentioned groove; and corresponding indicia on the gauge bar readable against said indicia on the body to express the deviation of the walls of said second groove as determined by the penetration depth of the gauge bar within said groove upon engagement of the end portion with the opposing walls of said second groove.
Claim 8
Dependent Claim
184 words
