Abstract

A belt pulling tool is comprised of a handle, a body and two prongs, the handle and body each having two ends with one end of each being attached to the other forming a longitudinal length and the two prongs being attached to the body orthogonal to the length, wherein at least one prong is configured to be moved and fixed along a portion of the length of the body. The belt pulling tool is useful for aligning, seating and setting the tension of belts for industrially belt driven machinery. In performing the method, the belt is inserted between the gap between the prongs of the tool and the tool is rotated about an axis centered in the gap and running parallel to the prongs projecting from the body of the tool to engage the belt and cause the rotation of the sheaves, thus allowing the sheaves to be aligned using alignment tools and allowing the belt to properly seat. Once seated and aligned, the tension may be set using a belt tension gauge.

First claim

What is claimed is:

1. A belt pulling tool comprising:
a handle,
a body and two prongs, the handle and body each having two ends with one end of each being attached to the other forming a longitudinal length and the two prongs being attached to the body orthogonal to the length,
the body having a prong accepting slot for receiving the prongs, the slot extending along a portion of the length of the body, the slot having an open end on a bottom face of the body, the bottom face being a distalmost body face from the handle,
wherein at least one prong is configured to be moved and fixed along a portion of the body parallel or nearly parallel to the longitudinal length.

2. A belt pulling tool comprising:
a handle,
a body and two prongs, the handle and body each having two ends with one end of each being attached to the other forming a longitudinal length and the two prongs being attached to the body orthogonal to the length,
wherein at least one prong is configured to be moved and fixed along a portion of the body parallel or nearly parallel to the longitudinal length,
wherein the body has walls defining a top face, bottom face, sides such that the distance between top and bottom face define a body thickness and the distance between the sides define a body width, said body width and thickness being orthogonal to the length and the body has a prong accepting slot running along the length of the top face with a slot depth and slot width that only partially traverses the body thickness and body width,
wherein at least one prong has a prong attachment end and distal end defining a prong length, the prong having a flat surface on a portion of the length starting from the prong attachment end with said prong attachment end being configured to be accepted into the slot of the body, and
wherein the body has a second slot on the bottom face mirroring the prong accepting slot.

3. The belt pulling tool of claim 2 , wherein the body has one or more holes for fastening the prongs to the body with a fastener.

4. The belt pulling tool of claim 1 , wherein a prong has a surface that has a texture or composition that improves the ability of the prongs to grip a drive belt.

5. The belt pulling tool of claim 4 , wherein the surface is knurled.

6. A belt pulling tool comprising:
a handle,
a body and two prongs, the handle and body each having two ends with one end of each being attached to the other forming a longitudinal length and the two prongs being attached to the body orthogonal to the length,
wherein at least one prong is configured to be moved and fixed along a portion of the body parallel or nearly parallel to the longitudinal length,
wherein the prongs have a cross-sectional shape that is a circle, oval, polygon or combination thereof,
wherein the cross-sectional shape is a circle for a portion of the length of the prong and a polygon for the remaining portion, and
wherein the polygon comprises two opposing straight lines connected by arcs.

7. The belt pulling tool of claim 6 , wherein the polygon is comprised of two opposing straight lines connected by arcs.

8. The belt pulling tool of claim 1 , wherein said tool is comprised of aluminum or alloy thereof.

9. The belt pulling tool of claim 1 wherein the slot has a closed end on a top face of the body, the top face being a proximate-most body face to the handle.

10. The belt pulling tool of claim 9 wherein the body has a width that is greater than the width of the handle.
