Abstract
Abstract A splice for toothed power transmission belts having connecting pins for holding the abutting ends of the belt together. The connecting pins each pass through a tooth of the belt in the splice region. The pin is placed in adjacent proximity to the tension cords in the belt so that these reinforcement cords will acquire the load transmitted to the pin. As a result, a stronger and more durable splice is achieved. The above splice may also be used for repairing damaged or worn belts by inserting a new piece of belt having a splice at each end.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
96 words
The method of forming a splice in abutting ends of a toothed power transmission belt having reinforcement cords running longitudinally along said belt, comprising the steps of: a. forming a splice configuration in the abutting ends of said belt featuring interengaging, interlocking male and female tongues; and then b. inserting at least one connecting pin through said tongues so as to transversely extend across said belt and lock said belt ends together, each pin fitting into a respective tooth member within said splice configuration, and disposed immediately below and within adjacent proximity to said reinforcement cords.
Claim 2
Independent Claim
96 words
The method of forming a splice in abutting ends of a toothed power transmission belt having reinforcement cords running longitudinally along said belt, comprising the steps of: a. forming a splice configuration in the abutting ends of said belt featuring interengaging, interlocking male and female tongues; and then b. inserting at least one connecting pin through said tongues so as to transversely extend across said belt and lock said belt ends together, each pin fitting into a respective tooth member within said splice configuration, and disposed immediately below and within adjacent proximity to said reinforcement cords.
Claim 3
Dependent Claim
33 words
The method of claim 1, further comprising the step of: c. clamping the belt about said splice to hold said belt ends in place prior to inserting the connecting pins into the belt.
Claim 4
Dependent Claim
23 words
The method of claim 1, wherein said pins are inserted into the belt by concurrently rotating and forcing said pins into the belt.
Claim 5
Dependent Claim
23 words
The method of claim 1, wherein said pins are inserted into the belt by fitting them into holes of a smaller diametrical size.
Claim 6
Dependent Claim
19 words
The method of claim 1, wherein said splice may be used to repair a damaged, worn, or broken belt.
