Abstract
Abstract There is disclosed herein a shank and socket joint wherein a mating socket cavity is oversize to provide clearance around the shank. A particle filled, thixotropic adhesive is disposed within the clearance, the particles being disposed at random intervals around the shank and being of such size as to center the shank within the socket.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
133 words
A shank and socket joint for joining a loosely fitting shank of one member to means affording a mating socket cavity of another member; said mating socket cavity being of substantially larger cross-sectional dimension than said shank and providing a substantially uniform clearance around said shank; a hardenable thixotropic adhesive material disposed at rest said clearance; small, solid, relatively heavy discrete particles disposed throughout said adhesive material at random spaced intervals in said clearance for maintaining uniform spacing of said shank with respect to said socket cavity and centering said shank within said socket cavity, said thixotropic adhesive material in said initially flowable form having the characteristic of increasing its viscosty when at rest so as to maintain said particles at said spaced intervals and center said shank until said adhesive material hardens.
Claim 2
Dependent Claim
133 words
A shank and socket joint for joining a loosely fitting shank of one member to means affording a mating socket cavity of another member; said mating socket cavity being of substantially larger cross-sectional dimension than said shank and providing a substantially uniform clearance around said shank; a hardenable thixotropic adhesive material disposed at rest said clearance; small, solid, relatively heavy discrete particles disposed throughout said adhesive material at random spaced intervals in said clearance for maintaining uniform spacing of said shank with respect to said socket cavity and centering said shank within said socket cavity, said thixotropic adhesive material in said initially flowable form having the characteristic of increasing its viscosty when at rest so as to maintain said particles at said spaced intervals and center said shank until said adhesive material hardens.
Claim 3
Dependent Claim
35 words
A shank and socket joint as set forth in claim 1: said discrete particles comprising small metal pellets of a size which is insertable within said clearance and maintains said clearance uniform around said shank.
Claim 4
Dependent Claim
33 words
A shank and socket joint as set forth in claim 1: said discrete particles comprising sand of a size which is insertable within said clearance and maintains said clearance uniform around said shank.
Claim 5
Dependent Claim
22 words
A shank and socket joint as set forth in claim 1: said shank and mating socket cavity being circular in transverse section.
Claim 6
Dependent Claim
22 words
A shank and socket joint as set forth in claim 1: said shank and mating socket cavity being noncircular in transverse section.
Claim 7
Dependent Claim
32 words
A shank and socket joint as set forth in claim 1: said shank having wall portions parallel with each other and parallel with all of the wall portions of said socket cavity.
