Abstract

Abstract A device for straightening wheel suspension beams on a vehicle consisting of a bifurcated frame between the sides of which is pivotally mounted either a fluid operated or mechanical jack having a force exerting member thereon arranged to engage a beam to be straightened. The frame may be suspended to the beam, and the force exerting member of the jack is engaged with the beam in position to exert a force thereagainst to straighten same. The jack is confined between the side members of the frame so that in the event it should become disengaged from the beam it is prevented from moving outwardly of the frame which might come into contact with and injure workmen using same. The suspending members for suspending the frame to the beam may be attached at selected locations along the upper sides of the beam so that the fluid pressure operated jack when employed therewith can either be placed between the suspension members to exert a straight force between the suspension members or the suspension members may be placed at one side of the force exerting member of the jack to allow the jack to engage the beam angularly with reference to the frame so that a bending force can be exerted against the beam to bend same outwardly of the suspension members.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 108 words
In a wheel alignment device, a frame, including spaced side members; parallel spaced apart rails connecting the side members at one end thereof; at least one transverse spacer member secured between the side members; a jack; means pivotally mounting the jack to the frame at the end thereof opposite said rails, said jack being freely extended between the side members and the rails and confined therebetween against movement outwardly of the frame; means attached to the rails for suspending the frame to a beam to be straightened; and a force exerting member movably extending from the free end of the jack engageable with a beam to be straightened.
Claim 2
Dependent Claim 108 words
In a wheel alignment device, a frame, including spaced side members; parallel spaced apart rails connecting the side members at one end thereof; at least one transverse spacer member secured between the side members; a jack; means pivotally mounting the jack to the frame at the end thereof opposite said rails, said jack being freely extended between the side members and the rails and confined therebetween against movement outwardly of the frame; means attached to the rails for suspending the frame to a beam to be straightened; and a force exerting member movably extending from the free end of the jack engageable with a beam to be straightened.
Claim 3
Dependent Claim 40 words
The combination called for in claim 1 with the addition of adjustment means between the suspension means and the rail to permit the suspension means to be attached either at one side of or on both sides of the jack.
Claim 4
Dependent Claim 40 words
The combination called for in claim 2 wherein the adjuStment means comprises spaced aligned holes in the rails, and holes in the suspension means arranged to be brought into alignment therewith; and detachable fastening means extendible through the aligned holes.
Claim 5
Dependent Claim 16 words
The combination called for in claim 1 wherein the jack is a pressure fluid operated jack.
Claim 6
Dependent Claim 15 words
The combination called for in claim 1 wherein the jack is a mechanically operated jack.
Claim 7
Dependent Claim 32 words
The combination called for in claim 5 with the addition of a mounting plate secured between the side members; and the base plate on the jack detachably secured to the mounting plate.
Claim 8
Dependent Claim 68 words
The combination called for in claim 5 with the addition of a jack mounting member comprising a body having a bolt receiving bore therethrough arranged to pivotally mount same to the frame; a threaded projection on the mounting plate arranged to be threadedly engaged with the threaded projection on the body; a base plate on the jack; and means to secure the mounted plate to the base plate.
Claim 9
Dependent Claim 60 words
The combination called for in claim 4 wherein the member for pivotally mounting the jack to the frame comprises a hollow body having a transverse bore therein arranged to receive a mounting member; means on the body for engagement thereof with the cylinder of the jack; and means on the body for engagement thereof with a source of pressure fluid.
