Abstract
Abstract An improved automotive type V-belt being of a truncated trapezoidal shape in cross-sectional dimension, the belting being endless and molded or otherwise formed around a flexible metal or plastic strapping type material, the strapping material being similarly endless and having evenly longitudinally spaced apertures throughout its length. The belting can be cut to any desired length, the belting drawn back from the strapping and the ends of the strapping suitably joined with a fastener through the apertures, after which the belting ends may be released to again cover the strapping and meet in end to end smoothly abutting relationship.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
108 words
Automotive belting comprising: (a) an endless strip of composition belting trapezoidal in cross-sectional dimension; (b) said belting continuously circumscribing an elongated flat flexible joinder strapping slightly lesser in width than the widest parallel wall of said trapezoid but disposed within said belting adjacent said wall; (c) said strapping being provided with equidistantly spaced apertures throughout the entire length of its longitudinal centerline axis; (d) said composition belting being deformable so that it may be manually pushed back along each end of a segment of said belting to expose sufficient strapping to expose at least one said longitudinal aperture at each end of a segment for interconnecting said ends.
Claim 2
Dependent Claim
108 words
Automotive belting comprising: (a) an endless strip of composition belting trapezoidal in cross-sectional dimension; (b) said belting continuously circumscribing an elongated flat flexible joinder strapping slightly lesser in width than the widest parallel wall of said trapezoid but disposed within said belting adjacent said wall; (c) said strapping being provided with equidistantly spaced apertures throughout the entire length of its longitudinal centerline axis; (d) said composition belting being deformable so that it may be manually pushed back along each end of a segment of said belting to expose sufficient strapping to expose at least one said longitudinal aperture at each end of a segment for interconnecting said ends.
Claim 3
Dependent Claim
35 words
The structure as set forth in claim 1, wherein said exposed strapping ends are overlayed until said apertures register and a fastener is permanently secured through said apertures to hold said strapping in overlayed position.
