Abstract
Abstract A hinge pin including two substantially identical sections which when assembled form a cylindrical sleeve. Each section has a first end having a cross-section greater than a semi-circle which tapers along its length to a second end having a cross-section less than a semi-circle. When the two sections are joined together, they form a cylindrical sleeve for use as a readily removable hinge pin. Ready removal is effectuated by sliding one section away from the other along their tapered lengths, the taper enabling the average diameter of the sleeve to decrease as the two sections are so slid apart.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
62 words
A disassemblable hinge pin comprising: two substantially identical sections defining a cylindrical sleeve when assembled, each section tapering over its length from a first end having a cross-section greater than a semi-circle to a second end having a cross-section smaller than a semi-circle, at least one of said sections including means mounted interiorly thereof for engaging a wheel puller or the like.
Claim 2
Dependent Claim
62 words
A disassemblable hinge pin comprising: two substantially identical sections defining a cylindrical sleeve when assembled, each section tapering over its length from a first end having a cross-section greater than a semi-circle to a second end having a cross-section smaller than a semi-circle, at least one of said sections including means mounted interiorly thereof for engaging a wheel puller or the like.
Claim 3
Dependent Claim
18 words
The hinge pin of claim 1 wherein said engaging means includes a plate having an aperture extending therethrough.
Claim 4
Dependent Claim
15 words
The hinge pin of claim 2 wherein said plate is provided with a threaded aperture.
Claim 5
Dependent Claim
137 words
A disassemblable hinge pin for interconnecting an axle bracket to a walking beam by insertion of the hinge pin through concentric apertures in the bracket and walking beam, said hinge pin comprising: two substantially identical sections which together define a generally cylindrical sleeve, each of said sections being longitudinally tapered from a first end having a cross-section greater than a semi-circle to a second end having a cross-section less than a semi-circle, said sections being slidable along each other so that the average cross-sectional area of the sleeve decreases as said sections are slidably moved apart, thereby facilitating removal of said sections from interconnecting the axle bracket and walking beam, at least one of said sections including a threaded, apertured plate mounted interiorly thereof for operative interengagement with the threads on a wheel puller or the like.
Claim 6
Dependent Claim
137 words
A disassemblable hinge pin for interconnecting an axle bracket to a walking beam by insertion of the hinge pin through concentric apertures in the bracket and walking beam, said hinge pin comprising: two substantially identical sections which together define a generally cylindrical sleeve, each of said sections being longitudinally tapered from a first end having a cross-section greater than a semi-circle to a second end having a cross-section less than a semi-circle, said sections being slidable along each other so that the average cross-sectional area of the sleeve decreases as said sections are slidably moved apart, thereby facilitating removal of said sections from interconnecting the axle bracket and walking beam, at least one of said sections including a threaded, apertured plate mounted interiorly thereof for operative interengagement with the threads on a wheel puller or the like.
