Abstract
Abstract A tool to remove shock absorbers from an automobile comprising an elongated barrel or tubular portion have a hollow bore extending therethrough and a ribbed socket at one end to receive the retaining nut at the top of a shock absorber mounted on an automobile. The barrel or tubular portion has an abutment flange extending outwardly along the side wall to catch and bear against a portion of the A-frame part of the vehicle which is adjacent to the shock absorber. The abutment flange keeps the barrel or tubular portion of the tool from rotating and holds the retaining nut received in the socket of the tool from rotating. A socket wrench is inserted down through the bore of the barrel or tubular portion of the tool to receive the head of the bolt or rod which holds the shock absorber in place. The cross-sectional configuration of the cavity of the socket wrench corresponds to the cross-sectional configuration of the head of the shock absorber bolt, whereby the bolt or rod can be rotated to unscrew from the retaining nut while the latter is held by the barrel or tubular portion of the tool having its abutment flange engaged against a portion of the A-frame to keep it and the retaining nut from rotating. The threaded portion of the rod or bolt is rotated until it has become completely disengaged from the retaining nut after which the shock absorber can be removed.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
358 words
A combination vehicle, shock absorber and tool to remove said shock absorber from said vehicle, wherein said vehicle includes a first frame portion and a second frame portion, said first frame portion being relatively fixed in relation to the body of said vehicle, said second frame portion being relatively fixed in relation to a corresponding one of the axles and wheels of said vehicle, said shock absorber having a shock absorbing cylindrical member connected at one end to said second frame portion, and a reciprocating rod member connected at the oposite end of said shock absorber to said first frame portion, a retaining nut, said retaining nut connecting said shock absorber to said first frame portion, said first frame portion including a well having a peripheral side wall defining a cavity other than circular in cross-section in which a first portion of said side wall is relatively closer to the central axis of said well, a second portion of said side wall which is relatively farther from the central axis of said well than said first portion, said well including a bottom floor thereof, an aperture through said floor centered on its said central axis, the upper end of said reciprocating rod member of said shock absorber extending through said aperture into said well, said retaining nut being threaded on said upper end of said rod member, said tool comprising an elongated tubular member, a first opening to one end of a through-passageway through said tubular member, a second opening to the opposite end of said through-passageway, said second opening being annular and including engagement means to receive and engage said retaining nut of said shock absorber to hold against rotation relative to said tubular member, and projecting means projecting outwardly from said elongated tubular member, said projection means having an outermost edge, the distance between the outermost edge of said projection means and said central axis when said tubular member is seated on said retaining nut being greater than the distance of said first portion of said side wall to said central axis and less than the distance of said second portion thereof to said central axis.
Claim 2
Dependent Claim
358 words
A combination vehicle, shock absorber and tool to remove said shock absorber from said vehicle, wherein said vehicle includes a first frame portion and a second frame portion, said first frame portion being relatively fixed in relation to the body of said vehicle, said second frame portion being relatively fixed in relation to a corresponding one of the axles and wheels of said vehicle, said shock absorber having a shock absorbing cylindrical member connected at one end to said second frame portion, and a reciprocating rod member connected at the oposite end of said shock absorber to said first frame portion, a retaining nut, said retaining nut connecting said shock absorber to said first frame portion, said first frame portion including a well having a peripheral side wall defining a cavity other than circular in cross-section in which a first portion of said side wall is relatively closer to the central axis of said well, a second portion of said side wall which is relatively farther from the central axis of said well than said first portion, said well including a bottom floor thereof, an aperture through said floor centered on its said central axis, the upper end of said reciprocating rod member of said shock absorber extending through said aperture into said well, said retaining nut being threaded on said upper end of said rod member, said tool comprising an elongated tubular member, a first opening to one end of a through-passageway through said tubular member, a second opening to the opposite end of said through-passageway, said second opening being annular and including engagement means to receive and engage said retaining nut of said shock absorber to hold against rotation relative to said tubular member, and projecting means projecting outwardly from said elongated tubular member, said projection means having an outermost edge, the distance between the outermost edge of said projection means and said central axis when said tubular member is seated on said retaining nut being greater than the distance of said first portion of said side wall to said central axis and less than the distance of said second portion thereof to said central axis.
Claim 3
Dependent Claim
191 words
A combination vehicle, shock absorber and tool to remove a shock absorber from a vehicle as set forth in claim 1, wherein said upper end of said reciprocating rod member includes a pair of opposed flat faces to receive a socket tool having a cavity of corresponding cross-section thereon for rotation of said rod member, a socket tool having said corresponding cross-section received through said through-passageway of said tubular member to seat on said upper end of said rod member, an extension shaft extending from said socket tool having a length sufficient to extend outwardly from beyond said first opening of said through-passageway of said tubular member when said socket tool is seated on said upper end of said rod member of said shock absorber, and means to rotate said extension shaft and said socket tool and said rod member in a direction to remove said rod member from said retaining nut held by said tubular member in seated engagement on said retaining nut with its said projecting means in abutting relationship against said first portion of said side wall of said well of said first frame member of said vehicle.
Claim 4
Dependent Claim
46 words
A combination vehicle, shock absorber and tool to remove a shock absorber from a vehicle as set forth in claim 1, wherein said first frame portion of said vehicle has an A-shaped exterior configuration and an opening at the top thereof opening to said well thereof.
Claim 5
Dependent Claim
38 words
A combination vehicle, shock absorber and tool to remove a shock absorber from a vehicle as set forth in claim 2, wherein said means to rotate said extension shaft includes a handle extending from the upper end thereof.
Claim 6
Dependent Claim
57 words
A combination vehicle, shock absorber and tool to remove said shock absorber from said vehicle as set forth in claim 1, wherein said engagement means of said second opening of said tubular member includes a plurality of spaced apart vertically extending ribs to grip and bear against said retaining nut when said engagement means is seated thereon.
Claim 7
Dependent Claim
38 words
A combination vehicle, shock absorber and tool to remove said shock absorber from said vehicle as set forth in claim 1, wherein said engagement means of said second opening of said tubular member comprises a nut engaging socket.
Claim 8
Dependent Claim
62 words
A combination vehicle, shock absorber and tool to remove said shock absorber from said vehicle as set forth in claim 1, wherein said projection means projecting outwardly from said elongated tubular member includes an elongated flange extending along the outer wall of said tubular member in a direction substantially parallel with the central axis of said through-passageway extending through said tubular member.
Claim 9
Dependent Claim
36 words
A combination vehicle, shock absorber and tool to remove said shock absorber from said vehicle as set forth in claim 7, wherein said elongated flange is integrally formed with said outer wall of said tubular member.
