Abstract
Abstract The invention described herein is a belt alignment mechanism for causing the belt of a belt driven vehicle to run true. In such vehicles, the belt runs around wheels and often such belts have a tendency to run to one side of the wheels or in other words not run true. By angling one of the wheels in a direction opposite to the direction the belt runs untrue, the belt can be made to run true. The belt alignment mechanism described herein has a member for angling one of the wheels and a jack for fixing the wheel in the angled position so the belt runs true.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
91 words
For a belt driven vehicle having a belt drive system having a front wheel and a rear wheel around which a belt runs, a belt alignment mechanism the function of which is independent of the steering of said vehicle, comprising: a member having a first end connected to one of said wheels; a means for angling said first end of said member thus angling said one of said wheels to an angled position; and a means for fixing said first end of said member and said wheel at said angled position.
Claim 2
Dependent Claim
91 words
For a belt driven vehicle having a belt drive system having a front wheel and a rear wheel around which a belt runs, a belt alignment mechanism the function of which is independent of the steering of said vehicle, comprising: a member having a first end connected to one of said wheels; a means for angling said first end of said member thus angling said one of said wheels to an angled position; and a means for fixing said first end of said member and said wheel at said angled position.
Claim 3
Dependent Claim
14 words
The belt alignment mechanism of claim 1, said member providing support to said wheel.
Claim 4
Dependent Claim
45 words
The belt alignment mechanism of claims 1 or 2, said member being elongate and further comprising a second end and a mid-portion which is fixed from lateral movement and about which the first and second ends of said member are pivotal in opposite lateral directions.
Claim 5
Dependent Claim
30 words
The belt alignment mechanism of claims 1 or 2, said angled position fixing means being a pair of opposing jack members each of which contacts opposing sides of said member.
Claim 6
Dependent Claim
83 words
For a belt driven vehicle having a belt drive system mounted on a roller frame, said belt drive system having a front wheel and a rear wheel around which a belt runs, a belt alignment mechanism the function of which is independent of the steering of said vehicle, comprising: a member connected to said roller frame having a first end connected to one of said wheels, a second end and a mid-portion; and said mid-portion of said member being fixed from lateral movement.
Claim 7
Dependent Claim
83 words
For a belt driven vehicle having a belt drive system mounted on a roller frame, said belt drive system having a front wheel and a rear wheel around which a belt runs, a belt alignment mechanism the function of which is independent of the steering of said vehicle, comprising: a member connected to said roller frame having a first end connected to one of said wheels, a second end and a mid-portion; and said mid-portion of said member being fixed from lateral movement.
Claim 8
Dependent Claim
53 words
The belt alignment mechanism of claim 5, a part of said roller frame being a hollow frame, said member being at least partially housed within said hollow frame such that said second end of said member is within said hollow frame and said first end of said member is outside said hollow frame.
Claim 9
Dependent Claim
141 words
In a belt driven vehicle having a belt drive system, said belt drive system having a front wheel and a rear wheel around which a belt runs, a belt alignment mechanism comprising a member having a first end connected to one of said wheels, a second end and a mid-portion fixed from lateral movement, a method for causing said belt to run true, comprising the steps of: laterally moving said second end of said member in the direction which the belt runs untrue causing said member to pivot about said mid-portion thus causing said first end of said member and the wheel to which said first end is connected to be angled in the direction opposite to which said belt runs untrue to an angled position; and fixing said member from lateral movement thus fixing said wheel at said angled position.
Claim 10
Dependent Claim
141 words
In a belt driven vehicle having a belt drive system, said belt drive system having a front wheel and a rear wheel around which a belt runs, a belt alignment mechanism comprising a member having a first end connected to one of said wheels, a second end and a mid-portion fixed from lateral movement, a method for causing said belt to run true, comprising the steps of: laterally moving said second end of said member in the direction which the belt runs untrue causing said member to pivot about said mid-portion thus causing said first end of said member and the wheel to which said first end is connected to be angled in the direction opposite to which said belt runs untrue to an angled position; and fixing said member from lateral movement thus fixing said wheel at said angled position.
Claim 11
Dependent Claim
110 words
For a belt driven vehicle having a belt drive system having a front wheel and a rear wheel around which a belt runs, a belt alignment mechanism, comprising: an elongate member having a first end connected to one of said wheels, a second end and a mid-portion which is fixed from lateral movement and about which said first and said second ends of said member are pivotal in opposite lateral directions; a means for angling said first end of said member thus angling said one of said wheels to an angled position; and a means for fixing said first end of said member and said wheel at said angled position.
Claim 12
Dependent Claim
110 words
For a belt driven vehicle having a belt drive system having a front wheel and a rear wheel around which a belt runs, a belt alignment mechanism, comprising: an elongate member having a first end connected to one of said wheels, a second end and a mid-portion which is fixed from lateral movement and about which said first and said second ends of said member are pivotal in opposite lateral directions; a means for angling said first end of said member thus angling said one of said wheels to an angled position; and a means for fixing said first end of said member and said wheel at said angled position.
Claim 13
Dependent Claim
92 words
For a belt driven vehicle having a belt drive system having a front wheel and a rear wheel around which a belt runs, a belt alignment mechanism, comprising: a member having a first end connected to one of said wheels; a means for angling said first end of said member thus angling said one of said wheels to an angled position; and a pair of opposing jack members each of which contacts opposing sides of said member for fixing said first end of said member and said wheel at said angled position.
Claim 14
Dependent Claim
92 words
