Abstract
Abstract A track-type vehicle comprises a pair of track roller frames pivotally mounted on either side thereof. Each of the frames comprises a tubular guard including a pair of longitudinally disposed members secured together by a pair of upper and lower welds extending substantially the full length of the frame and disposed medianly thereon. Each of the members is initially formed with an upwardly projecting flat portion which is thereafter bent inwardly to have its end secured to an adjacent end of the other member by the upper weld.

Claim 1
Independent Claim
75 words
In a track-type vehicle of the type comprising a pair of metallic track roller frames mounted on either side thereof and a plurality of track rollers rotatably mounted on each of said frames, the improvement wherein each of said frames comprises a tubular guard including a pair of longitudinally disposed substantially identical members secured together at pairs of upper and lower edges thereof disposed medianly of said guard and extending substantially the full length thereof.
Claim 2
Dependent Claim
75 words
In a track-type vehicle of the type comprising a pair of metallic track roller frames mounted on either side thereof and a plurality of track rollers rotatably mounted on each of said frames, the improvement wherein each of said frames comprises a tubular guard including a pair of longitudinally disposed substantially identical members secured together at pairs of upper and lower edges thereof disposed medianly of said guard and extending substantially the full length thereof.
Claim 3
Dependent Claim
34 words
The vehicle of claim 1 wherein said members each comprises an arcuate first wall portion and a second wall portion extending inwardly from said first wall portion in underlying and vertically spaced relationship therewith.
Claim 4
Dependent Claim
21 words
The vehicle of claim 2 wherein said first wall portions are secured together at adjacent edges thereof by a common weld.
Claim 5
Dependent Claim
21 words
The vehicle of claim 3 wherein said seond wall portions are secured together at adjacent edges thereof at a common weld.
Claim 6
Dependent Claim
40 words
The vehicle of claim 1 wherein each of said members comprises a support portion extending downwardly from said first wall portion and below said second wall portion and further comprising a track roller assembly releasably attached to said support portions.
Claim 7
Dependent Claim
40 words
The vehicle of claim 1 further comprising means forming a slot at a forward end of said members and further comprising an idler rotatably mounted on a forward end of said guard and at least partially disposed in said slot.
Claim 8
Dependent Claim
38 words
The vehicle of claim 6 wherein said idler assembly comprises a bracket secured on each end of a shaft thereof, said bracket comprising a hook portion engaging a bearing surface formed on a respective one of said members.
Claim 9
Dependent Claim
47 words
The vehicle of claim 7 wherein each end of a shaft carrying said idler thereon is disposed in an elongated slot formed through a sidewall of said guard and further comprising a recoil mechanism disposed in said guard and operatively connected to the shaft of said idler.
Claim 10
Independent Claim
92 words
A method for making a tubular guard for a track roller frame of a track-type vehicle comprising the steps of forming a pair of substantially identical metallic members to each comprise a generally upright first wall portion and a second wall portion extending inwardly from said first wall portion bending the first wall portion of each of said members into overlying relationship relative to a respective second wall portion first securing said first wall portions together longitudinally and medianly thereof, and second securing said second wall portions together longitudinally and medianly thereof.
Claim 11
Independent Claim
92 words
A method for making a tubular guard for a track roller frame of a track-type vehicle comprising the steps of forming a pair of substantially identical metallic members to each comprise a generally upright first wall portion and a second wall portion extending inwardly from said first wall portion bending the first wall portion of each of said members into overlying relationship relative to a respective second wall portion first securing said first wall portions together longitudinally and medianly thereof, and second securing said second wall portions together longitudinally and medianly thereof.
Claim 12
Dependent Claim
21 words
The method of claim 9 wherein said bending step comprises bending each of said first wall portions into an arcuate configuration.
Claim 13
Dependent Claim
24 words
The method of claim 9 wherein said first securing step comprises securing adjacent edges of said first wall portions together by a common weld.
Claim 14
Dependent Claim
24 words
The method of claim 11 wherein said second securing step comprises securing adjacent edges of said second wall portions together by a common weld.
Claim 15
Dependent Claim
46 words
The method of claim 9 further comprising the step of forming an elongated support portion coextensively relative to each of said first wall portions and vertically below a respective second wall portion and attaching a track roller assembly laterally between the support portions of said members.
Claim 16
Dependent Claim
56 words
The method of claim 13 further comprising the step of forming slots in said first wall portions and said second wall portions so that said slots extend medianly and longitudinally towards an aft end of said guard and rotatably mounting an idler on a forward end of said guard and at least partially within said slot.
