Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
74 words
A mounting assembly for movably supporting a rotatable member, said assembly comprising: a pair of spaced substantially parallel frames, each of said frames having a pair of vertically spaced substantially parallel planer bearing surfaces, said bearing surfaces defining the upper and lower limits of said frames; axle means for rotatably supporting a rotatable member; and bracket means slidably embracing said bearing surfaces to mount said axle means between said frames intermediate said bearing surfaces.
Claim 2
Dependent Claim
74 words
A mounting assembly for movably supporting a rotatable member, said assembly comprising: a pair of spaced substantially parallel frames, each of said frames having a pair of vertically spaced substantially parallel planer bearing surfaces, said bearing surfaces defining the upper and lower limits of said frames; axle means for rotatably supporting a rotatable member; and bracket means slidably embracing said bearing surfaces to mount said axle means between said frames intermediate said bearing surfaces.
Claim 3
Dependent Claim
29 words
The mounting assembly of claim 1 wherein said axle means is an elongated shaft having opposite ends extending outwardly from said rotatable member for connection to said bracket means.
Claim 4
Dependent Claim
31 words
The mounting assembly of claim 2 wherein each of said frames has an inwardly opening recess formed between said bearing surfaces with said ends of said shaft extending into said recesses.
Claim 5
Dependent Claim
58 words
The mounting assembly of claim 3 comprising a recoil mechanism secured to said frames in spaced relation to said mounting assembly and having a socket opening toward said rotatable member; a forked member secured to said bracket means; and, a rod secured at one end to said forked member and the other end loosely retained within said socket.
Claim 6
Dependent Claim
20 words
The invention of claim 3 wherein said rotatable member is a track idler, and said frame is a track frame.
Claim 7
Dependent Claim
109 words
A mounting assembly for slidably supporting an idler on a track frame, said assembly comprising: a pair of horizontally extending transversely spaced substantially parallel rail members, each rail member having a pair of vertically spaced substantially parallel bearing surfaces, defining the upper and lower limits of the rail member; a shaft disposed between said rail members; an idler rotatably mounted on said shaft intermediate the ends thereof; and, a pair of support brackets individually supporting the ends of said shaft and disposed between said rail members, each of said support brackets having a pair of outwardly extending projections arranged for slidably embracing said bearing surfaces of said rail members.
Claim 8
Dependent Claim
109 words
A mounting assembly for slidably supporting an idler on a track frame, said assembly comprising: a pair of horizontally extending transversely spaced substantially parallel rail members, each rail member having a pair of vertically spaced substantially parallel bearing surfaces, defining the upper and lower limits of the rail member; a shaft disposed between said rail members; an idler rotatably mounted on said shaft intermediate the ends thereof; and, a pair of support brackets individually supporting the ends of said shaft and disposed between said rail members, each of said support brackets having a pair of outwardly extending projections arranged for slidably embracing said bearing surfaces of said rail members.
Claim 9
Dependent Claim
32 words
The mounting assembly of claim 6 wherein each of said rail members has an inwardly opening recess formed between said mounting surfaces with said ends of said shaft protruding into said recesses.
Claim 10
Dependent Claim
56 words
The mounting assembly of claim 7 comprising a recoil mechanism mounted on said frame in spaced relation to said mounting assembly and including a socket opening toward said idler; a forked member secured to said brackets; and, a rod having one end secured to said forked member and the other end loosely retained within said socket.
Claim 11
Dependent Claim
59 words
The mounting device of claim 7 wherein each of said rail members has a guide surface formed thereon substantially normal to said bearing surfaces and each of said brackets has a guide surface formed thereon and adapted for slidable engagement with said guide surface of said rail member to maintain said idler in longitudinal alignment with said rail members.
