Abstract
Abstract A repair device for repairing broken cross rods or cleats on snowmobile drive belts or tracks where the cross rods or bars are molded into the track. The cleats are reinforcing and traction devices for the track, and also provide lugs against which the drive sprockets for the snowmobile track will run. The rods used are subject to breakage, and once broken, it is usually necessary to throw away the entire track or belt because the rods cannot be welded satisfactorily. The present device presents a repair unit for repairing the broken cross bars.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
130 words
A repair unit for a snowmobile drive track comprising a belt like member having a plurality of spaced cross rods extending thereacross against which snowmobile drive sprockets drive, said cross rods being subject to breaking from loads thereon, said repair unit including at least one generally tubular member, said tubular member having an inside cross section of size and shape to fit closely over a portion of one of said cross rods adjacent a break, a pair of flange members mounted on said tubular member and extending outwardly from the tubular member, said tubular member being offset from the flange members, and means to fasten said flange members to said track on opposite sides of said break to hold said portion of a broken cross rod inside said tubular member.
Claim 2
Dependent Claim
130 words
A repair unit for a snowmobile drive track comprising a belt like member having a plurality of spaced cross rods extending thereacross against which snowmobile drive sprockets drive, said cross rods being subject to breaking from loads thereon, said repair unit including at least one generally tubular member, said tubular member having an inside cross section of size and shape to fit closely over a portion of one of said cross rods adjacent a break, a pair of flange members mounted on said tubular member and extending outwardly from the tubular member, said tubular member being offset from the flange members, and means to fasten said flange members to said track on opposite sides of said break to hold said portion of a broken cross rod inside said tubular member.
Claim 3
Dependent Claim
58 words
The combination as specified in claim 1 wherein a section of said broken cross rod is removed adjacent said break to provide two spaced cross rod portions, the space between said spaced portions being of distance shorter than the length of said tubular member, whereby said tubular member overlaps portions of said broken cross rod adjacent said space.
Claim 4
Dependent Claim
45 words
The combination of claim 1 wherein said break is adjacent the portion of the cross rods against which drive sprockets drive, said tubular member having an outer surface of size and shape to provide a surface for drive sprockets to engage to drive said track.
Claim 5
Dependent Claim
63 words
The combination of claim 1 wherein said cross rods are molded into said belt-like member and are surrounded by molded material to form a hump extending transversely across said belt, said flange members including planar side portions and a joining section formed to fit over said hump when the side portions are resting on the belt-like member on opposite sides of said hump.
Claim 6
Independent Claim
152 words
A method of repairing a snowmobile drive track comprising a belt-like member having a plurality of transverse rods fixed to said belt-like member, said belt-like member having openings on opposite sides of the transverse rods in portions of said belt through which sprocket teeth may protrude to drive from said sprocket teeth to said belt, and wherein a breakage occurs in said transverse rods adjacent said openings, comprising the steps of removing a section of a broken transverse rod to leave two spaced rod portions, cleaning belt material from said rod portions as necessary to leave exposed ends of said transverse rod portions, mounting a member over both of the exposed ends of said rod portions to extend between the rod portions, and fastening said member in place on said belt on opposite sides of the removed rod section to hold the rod portions of said broken transverse rod in said member.
Claim 7
Independent Claim
152 words
A method of repairing a snowmobile drive track comprising a belt-like member having a plurality of transverse rods fixed to said belt-like member, said belt-like member having openings on opposite sides of the transverse rods in portions of said belt through which sprocket teeth may protrude to drive from said sprocket teeth to said belt, and wherein a breakage occurs in said transverse rods adjacent said openings, comprising the steps of removing a section of a broken transverse rod to leave two spaced rod portions, cleaning belt material from said rod portions as necessary to leave exposed ends of said transverse rod portions, mounting a member over both of the exposed ends of said rod portions to extend between the rod portions, and fastening said member in place on said belt on opposite sides of the removed rod section to hold the rod portions of said broken transverse rod in said member.
