Abstract
Abstract An endless V-belt of elastomeric material having a plurality of longitudinally spaced preferably T-shaped lug members embedded in the belt with portions of the lug extending radially outwardly of the belt and being adapted for attachment thereto. The method of making the belt includes applying layers of elastomeric material and reinforcing cords over a building drum to form an inverted belt carcass and then forming apertures in the carcass for receiving the lug members before completing fabrication and vulcanizing of the belt.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
91 words
An endless power transmission belt formed of vulcanized elastomeric material and having a V-shape in transverse section comprising: a. at least one reinforcement layer embedded in said belt; b. a plurality of lug members disposed in longitudinally spaced arrangement along said belt with each of said lug members having a base portion disposed radially inward of said reinforcement layer and a shank portion disposed to extend through said reinforcement and project from the outer periphery of said belt with the shank portion adapted for attachment of a rigid blade means thereto.
Claim 2
Dependent Claim
91 words
An endless power transmission belt formed of vulcanized elastomeric material and having a V-shape in transverse section comprising: a. at least one reinforcement layer embedded in said belt; b. a plurality of lug members disposed in longitudinally spaced arrangement along said belt with each of said lug members having a base portion disposed radially inward of said reinforcement layer and a shank portion disposed to extend through said reinforcement and project from the outer periphery of said belt with the shank portion adapted for attachment of a rigid blade means thereto.
Claim 3
Dependent Claim
21 words
The belt defined in claim 1, wherein said reinforcement layer includes at least one layer of longitudinally disposed flexible tension members.
Claim 4
Dependent Claim
19 words
The belt defined in claim 2, wherein said reinforcement further includes at least one layer of square woven fabric.
Claim 5
Dependent Claim
22 words
The belt defined in claim 1, wherein said shank and said base portions of said lug members are arranged in T-shaped configuration.
Claim 6
Dependent Claim
26 words
The belt defined in claim 1, wherein said shank portion of each of said lug members has an aperture formed therein for fastening a cutter thereto.
Claim 7
Independent Claim
171 words
The method of making an endless elastomeric power transmission belt of the V-type comprising the steps: a. providing at least one building drum; b. applying over said drum a plurality of layers of uncured elastomer having at least one layer of reinforcement therein; c. forming a plurality of longitudinally spaced apertures through the belt carcass; d. providing a plurality of lug members each having a shank portion adapted to interfit the said apertures and having means provided thereon with each of said members further having a base portion larger than said apertures; e. inserting the shank portion of one of said lug members through each of said apertures with said fastening means projecting beyond the surface of said tension cord layers and with the said second portion adjacent the said woven fabric; and, f. applying a base layer of uncured elastomeric material over the square woven fabric in superposed relationship; g. forming the belt to a substantially V-shaped cross-section; and, h. vulcanizing the belt to the said V-shape in a mold.
