Abstract
Abstract A device for measuring the circumference and section width of Vbelts while the belt is maintained under tension. The belt is tensioned over two half pulleys, one of which is mounted on a slide with a releasable locking wedge maintaining the latter a fixed distance along the slide to hold the belt under tension. A belt length indicating scale is provided on the slide and one of the half pulleys has a section-width indicating scale thereon which cooperates with the length indicating scale to provide a direct reading of both length and width of the belt.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
157 words
A device for measuring endless V-belts under tension comprising: a. an elongated guide member having a portion adapted to contact the inner periphery of a belt to be measured; b. slide means adapted to contact the inner periphery of said belt, said means being movably mounted on said guide member for tensioning the belt and having a locking portion formed thereon which portion is capable of being urged frictionally against said guide member such that movement of said slide means with respect to said guide member is prevented; c. locking means movably mounted on said guide member, said means releasably engaging said slide means for preventing movement of the latter on said guide member; said locking means having a portion thereof which frictionally contacts the locking portion of said slide means urging same into releasable contact with portions of said guide member when said locking means is moved along said guide member away from said slide means.
Claim 2
Independent Claim
157 words
A device for measuring endless V-belts under tension comprising: a. an elongated guide member having a portion adapted to contact the inner periphery of a belt to be measured; b. slide means adapted to contact the inner periphery of said belt, said means being movably mounted on said guide member for tensioning the belt and having a locking portion formed thereon which portion is capable of being urged frictionally against said guide member such that movement of said slide means with respect to said guide member is prevented; c. locking means movably mounted on said guide member, said means releasably engaging said slide means for preventing movement of the latter on said guide member; said locking means having a portion thereof which frictionally contacts the locking portion of said slide means urging same into releasable contact with portions of said guide member when said locking means is moved along said guide member away from said slide means.
Claim 3
Dependent Claim
90 words
The device defined in claim 1, wherein a. said locking portion of said slide means has an inclined surface thereon; b. said locking means has an inclined surface corresponding to the inclined surface on said slide means such that upon movement of said locking means away from said slide means and the said inclined surface of said locking means contacts the said inclined surface of said slide means and wedges the said locking portion of said slide means against said guide member thereby preventing movement of said slide means thereon.
Claim 4
Independent Claim
236 words
A device for measuring endless V-belts under tension comprising: a. an elongated guide member having a semi-circular portion formed at one end thereof grooved to receive a portion of the inner periphery of a belt, said member having a pair of spaced parallel ways formed along the edges thereof, the said ways adapted to receive a slide thereover; b. a slide member having a semicircular portion grooved to receive a portion of the inner periphery of a belt, and having a pair of rails provided thereon extending in spaced parallel relationship from said semicircular portion which rails are each slidably received in respectively one of the said ways and each of said rails has a cam portion formed adjacent the free end thereof; c. a locking member having a generally U-shaped configuration with the leg portions of the said U-shape each respectively slidably received in one of said ways of said guide and each of said leg portions has a locking cam portion formed adjacent the end thereof complementary to the respective cam portion on said guide member which locking cam is adapted to wedge thereagainst; d. spring means provided in each of said ways for urging each of said locking cam portions on said slide member into contact with the corresponding adjacent cam portion on said locking member and preventing movement of said slide member and said locking member with respect to said guide member.
Claim 5
Independent Claim
236 words
A device for measuring endless V-belts under tension comprising: a. an elongated guide member having a semi-circular portion formed at one end thereof grooved to receive a portion of the inner periphery of a belt, said member having a pair of spaced parallel ways formed along the edges thereof, the said ways adapted to receive a slide thereover; b. a slide member having a semicircular portion grooved to receive a portion of the inner periphery of a belt, and having a pair of rails provided thereon extending in spaced parallel relationship from said semicircular portion which rails are each slidably received in respectively one of the said ways and each of said rails has a cam portion formed adjacent the free end thereof; c. a locking member having a generally U-shaped configuration with the leg portions of the said U-shape each respectively slidably received in one of said ways of said guide and each of said leg portions has a locking cam portion formed adjacent the end thereof complementary to the respective cam portion on said guide member which locking cam is adapted to wedge thereagainst; d. spring means provided in each of said ways for urging each of said locking cam portions on said slide member into contact with the corresponding adjacent cam portion on said locking member and preventing movement of said slide member and said locking member with respect to said guide member.
Claim 6
Dependent Claim
54 words
The device defined in claim 3, wherein a measuring scale provided on said guide member which scale indicates the position of the semicircular portion of said slide means therealong, said scale being calibrated to indicate directly the length of a belt received over the semicircular portions of said guide member and said slide member.
Claim 7
Dependent Claim
80 words
The device defined in claim 3, wherein said grooved semicircular portion of said slide member has a radial notch formed in the edge of said groove such that the side of a belt received therein is exposed and said notch has a scale provided along one radial edge thereof which scale indicates the radial position of the outer periphery of a belt received in said groove, said scale being calibrated to indicate directly the cross-sectional width of such a belt.
