Abstract
Abstract A tractor comprises a main frame, an oscillating beam support subassembly mounted on the main frame, an oscillating beam mounted on the beam support for limited pivotal movement about the longitudinal axis of the tractor, and laterally spaced crawler units connected to the ends of the oscillating beam. The subassembly comprises a pair of longitudinally spaced apart vertically depending cross members, each having a mounting flange thereon. The oscillating beam is provided with a hole near the center thereof for receiving a pivot pin which is non-rotatably press-fitted therein. The ends of the pivot pin extend outwardly of the hole and are supported for pivotal movement in holes extending through bearing blocks which, in turn, are releasably bolted to the mounting flanges. Clearance between the ends of the pivot pin and the cross members is such as to prevent axial endwise shifting of the pivot pin if any such tendency should develop.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
219 words
In a vehicle: an oscillating beam, and means for releasably mounting said beam on said vehicle comprising a mounting assembly connected to said vehicle and including a pair of vertically disposed support members spaced apart a predetermined distance to define a space open at the bottom and in which said beam is pivotably mountable, with opposite sides of said beam confronting said support members, pin means non-rotatably connected to said beam and having pin ends projecting from opposite sides of said beam, each pin end having a circular transverse cross section, the distance between the outer end surfaces of said pin ends being less than said predetermined distance but sufficient to prevent substantial axial shifting of said pin means, a bearing member removably supported on each pin end for pivotably supporting said beam on said mounting assembly, each bearing member having a circular bore therein for accommodating a pin end and by means of which said beaRing member is removably supported on a pin end, said bore extending completely through said bearing member whereby the outer end surface of an associated pin end is adjacent an associated support member, bearing support means mounted on said mounting assembly between said support members, and connecting means for releasably connecting each bearing member to said bearing support means of said mounting assembly.
Claim 2
Dependent Claim
219 words
In a vehicle: an oscillating beam, and means for releasably mounting said beam on said vehicle comprising a mounting assembly connected to said vehicle and including a pair of vertically disposed support members spaced apart a predetermined distance to define a space open at the bottom and in which said beam is pivotably mountable, with opposite sides of said beam confronting said support members, pin means non-rotatably connected to said beam and having pin ends projecting from opposite sides of said beam, each pin end having a circular transverse cross section, the distance between the outer end surfaces of said pin ends being less than said predetermined distance but sufficient to prevent substantial axial shifting of said pin means, a bearing member removably supported on each pin end for pivotably supporting said beam on said mounting assembly, each bearing member having a circular bore therein for accommodating a pin end and by means of which said beaRing member is removably supported on a pin end, said bore extending completely through said bearing member whereby the outer end surface of an associated pin end is adjacent an associated support member, bearing support means mounted on said mounting assembly between said support members, and connecting means for releasably connecting each bearing member to said bearing support means of said mounting assembly.
Claim 3
Dependent Claim
49 words
A vehicle according to claim 1 wherein said beam is provided with a pin-receiving hole extending therethrough from said opposite sides thereof and wherein said pin means comprises a pin force-fitted and frictionally engaged in said pin-receiving hole whereby relative movement between said beam and said pin is prevented.
Claim 4
Dependent Claim
70 words
A vehicle according to claim 1 wherein said connecting means comprises a releasable threaded connecting member for each bearing member, a first hole in each bearing member for accommodating said connecting member, said first hole being transverse to the bore in its associated bearing member, and a second hole in said bearing support means of said mounting assembly and in registry with said first hole for accommodating said connecting member.
Claim 5
Dependent Claim
24 words
A vehicle according to claim 2 wherein said pin means is cylindrical and wherein said bore in each of said bearing members is cylindrical.
Claim 6
Dependent Claim
44 words
A vehicle according to claim 3 wherein said threaded connecting member is a capscrew, wherein said first hole accommodates the shank of said capscrew, and wherein said second hole is a threaded hole for receiving the threaded end of said capscrew in threaded engagement.
Claim 7
Dependent Claim
273 words
In a vehicle: an oscillating beam, and means for releasably mounting said beam on said vehicle comprising a mounting assembly connected to said vehicle and including a pair of vertically disposed spaced apart support members defining a space open at the bottom and in which said beam is pivotably mountable, each support member having bearing support means thereon within said space, a pair of spaced apart threaded bolt holes in each bearing support means, pin means nonrotatably connected to said beam and having cylindrical pin ends projecting from opposite sides of said beam, the distance between the outer end surfaces of said pin ends being less than the distance between said support members but sufficient to prevent substantial axial shifting of said pin means, a bearing member removably supported on each pin end for pivotably supporting said beam on said mounting assembly, each bearing member having a cylindrical bore extending therethrough for accommodating pin end and whereby the outer end surface of a pin end is adjacent an associated support member, the bore in each bearing member serving as a means by which the bearing member is removably supported on its associated pin end, each bearing member having a pair of spaced bolt holes therethrough transverse to said bore and in registry with said pair of threaded bolt holes in said bearing support means, and connecting means including a pair of bolts for each bearing member, each bolt extending through a bolt hole in a bearing member and into a threaded bolt hole in said bearing support means for releasably connecting each bearing member to an associated one of said bearing support means.
Claim 8
Dependent Claim
273 words
In a vehicle: an oscillating beam, and means for releasably mounting said beam on said vehicle comprising a mounting assembly connected to said vehicle and including a pair of vertically disposed spaced apart support members defining a space open at the bottom and in which said beam is pivotably mountable, each support member having bearing support means thereon within said space, a pair of spaced apart threaded bolt holes in each bearing support means, pin means nonrotatably connected to said beam and having cylindrical pin ends projecting from opposite sides of said beam, the distance between the outer end surfaces of said pin ends being less than the distance between said support members but sufficient to prevent substantial axial shifting of said pin means, a bearing member removably supported on each pin end for pivotably supporting said beam on said mounting assembly, each bearing member having a cylindrical bore extending therethrough for accommodating pin end and whereby the outer end surface of a pin end is adjacent an associated support member, the bore in each bearing member serving as a means by which the bearing member is removably supported on its associated pin end, each bearing member having a pair of spaced bolt holes therethrough transverse to said bore and in registry with said pair of threaded bolt holes in said bearing support means, and connecting means including a pair of bolts for each bearing member, each bolt extending through a bolt hole in a bearing member and into a threaded bolt hole in said bearing support means for releasably connecting each bearing member to an associated one of said bearing support means.
Claim 9
Dependent Claim
51 words
A vehicle according to claim 6 wherein said beam is provided with a cylindrical pin-receiving hole extending therethrough from said opposite sides thereof and wherein said pin means comprises a cylindrical pin force-fitted and frictionally engaged in said pin-receiving hole whereby relative movement between said beam and said pin is prevented.
