Claim 1
Independent Claim
250 words
In a method of making, a tensioner for a power transmission belt that is adapted to be operated in an endless path, said method comprising the steps of forming a support means for being fixed relative to said belt, forming a belt engaging means to be carried by said support means and be movable relative thereto, operatively associating mechanical spring means with said support means and said belt engaging means for urging said belt engaging means relative to said support means and against said belt with a force to tension said belt, forming said spring means to have a longitudinal axis and be spiraled about said axis thereof, forming said support means to comprise a shaft means having a longitudinal axis and be fixed from movement relative to said belt engaging means, forming said belt engaging means to have a portion thereof rotatably carried by said shaft means so as to rotate relative to said shaft means, forming said portion of said belt engaging means to have a slot therein, and forming said spring means to have an inner coil provided with an inner end bent at an angle relative to said inner coil and received in said slot to interconnect said spring means to said portion of said belt engaging means, the improvement comprising the step of disposing a protective member between said portion of said belt engaging means and said inner coil of said spring means adjacent said inner end thereof to tend to protect said inner coil.
Claim 2
Dependent Claim
250 words
In a method of making, a tensioner for a power transmission belt that is adapted to be operated in an endless path, said method comprising the steps of forming a support means for being fixed relative to said belt, forming a belt engaging means to be carried by said support means and be movable relative thereto, operatively associating mechanical spring means with said support means and said belt engaging means for urging said belt engaging means relative to said support means and against said belt with a force to tension said belt, forming said spring means to have a longitudinal axis and be spiraled about said axis thereof, forming said support means to comprise a shaft means having a longitudinal axis and be fixed from movement relative to said belt engaging means, forming said belt engaging means to have a portion thereof rotatably carried by said shaft means so as to rotate relative to said shaft means, forming said portion of said belt engaging means to have a slot therein, and forming said spring means to have an inner coil provided with an inner end bent at an angle relative to said inner coil and received in said slot to interconnect said spring means to said portion of said belt engaging means, the improvement comprising the step of disposing a protective member between said portion of said belt engaging means and said inner coil of said spring means adjacent said inner end thereof to tend to protect said inner coil.
Claim 3
Dependent Claim
58 words
A method of making a tensioner as set forth in claim 1 and including the steps of forming said portion of said belt engaging means to comprise a substantially cylindrical tubular portion telescopically disposed on said shaft means, and forming said protective member to be arcuate to substantially conform to said cylindrical tubular portion and said inner coil.
Claim 4
Dependent Claim
63 words
A method of making a tensioner as set forth in claim 2 and including the step of forming said protective member to be thickner adjacent said bent inner end of said spring means and have the thickness thereof decrease in a tapering manner as said protective member extends away from said bent inner end in a circumferential direction on said cylindrical tubular portion.
Claim 5
Dependent Claim
47 words
A method of making a tensioner as set forth in claim 3 and including the step of forming said protective member to have a part thereof disposed in said slot of said tubular portion to prevent rotational movement of said protective member relative to said tubular portion.
Claim 6
Dependent Claim
24 words
A method of making a tensioner as set forth in claim 1 and including the step of forming said protective member from polymeric material.
