Abstract
Abstract A vehicle torsion bar wheel mounting includes a square tubular member fixed to the body frame and centrally housing a coupling block. Rectangular torsion bars are pivoted at their inner ends to the coupling block and at their outer ends to outwardly projecting shafts provided at their ends with radially extending arms proximate the ends of which are mounted transverse wheel supporting axles. An anchoring block slidably engages each of the torsion bars and the inside faces of the tubular member and is releasably fixed at any preset position by set screws available through a slot in the tubular member to permit the adjustment of the effective lengths of the torsion bars and the springing of the respective wheels by adjusting the point at which each torsion bar is fixed against axial rotation.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
79 words
A vehicle wheel spring mounting comprising a longitudinally extending torsion bar, a longitudinally extending wheel supporting axle, means connecting said axle to an outer portion of said torsion bar and transversely offset from the longitudinal axis of said torsion bar for rocking with said outer portion about said longitudinal axis characterized by means for releasably locking said torsion bar against axial rotation at an adjustable preselected point along the length of said torsion bar inwardly of said outer portion.
Claim 2
Dependent Claim
79 words
A vehicle wheel spring mounting comprising a longitudinally extending torsion bar, a longitudinally extending wheel supporting axle, means connecting said axle to an outer portion of said torsion bar and transversely offset from the longitudinal axis of said torsion bar for rocking with said outer portion about said longitudinal axis characterized by means for releasably locking said torsion bar against axial rotation at an adjustable preselected point along the length of said torsion bar inwardly of said outer portion.
Claim 3
Dependent Claim
45 words
The mounting of claim 1 wherein said locking means comprises a slide member longiTudinally movable along said torsion bar and rotatable therewith, means restricting the rotation of said slide member, and means releasably locking said slide member in an adjustable preselected position against longitudinal movement.
Claim 4
Dependent Claim
44 words
The mounting of claim 2 wherein said torsion bar is of non-circular transverse cross section and said slide member comprises a block having a longitudinal bore of a transverse cross section corresponding to that of said torsion bar and slidably engaging said torsion bar.
Claim 5
Dependent Claim
54 words
The mounting of claim 3 wherein said block is of non-circular transverse cross section and said slide member rotation restricting means comprises a longitudinally extending tubular member housing said torsion bar and having an internal transverse cross section corresponding to that of said slide member, said slide member being slidable along said tubular member.
Claim 6
Dependent Claim
55 words
The mounting of claim 4 wherein said connecting means comprises a shaft extending through the outer end of said tubular member and connected at its inner end to the outer end of said torsion bar and a radial arm mounted in the outer end of said shaft and supporting said axle at its outer end.
Claim 7
Dependent Claim
70 words
The mounting of claim 4 comprising a coupling member disposed in said tubular member intermediate its ends and restricted against rotation about the longitudinal axis, a pair of said torsion bars housed in said tubular member and having their inner ends connected to said coupling member, one of said slide members engaging each of said torsion bars and one of said axles being connected to each of said torsion bars.
Claim 8
Dependent Claim
15 words
The mounting of claim 6 wherein said tubular member is of square transverse cross section.
Claim 9
Dependent Claim
15 words
The mounting of claim 6 wherein said torsion bars are pivoted to said coupling member.
Claim 10
Dependent Claim
140 words
A vehicle wheel spring mounting comprising a longitudinally extending torsion bar of non-circular transverse cross section, a longitudinally extending wheel supporting axle, means connecting said axle to an outer portion of said torsion bar and transversely offset from the longitudinal axis of said torsion bar for rocking with said outer portion about said longitudinal axis, and means for releasably locking said torsion bar against axial rotation at an adjustable preselected point along the length of said torsion bar inwardly of said outer portion and including a block having a longitudinal bore of a transverse cross section corresponding to that of said torsion bar and slidably engaging said torsion bar and having a tapped transverse bore communicating with said longitudinal bore and a set screw engaging said tapped bore and said torsion bar, and means restricting the rotation of said block.
Claim 11
Dependent Claim
140 words
A vehicle wheel spring mounting comprising a longitudinally extending torsion bar of non-circular transverse cross section, a longitudinally extending wheel supporting axle, means connecting said axle to an outer portion of said torsion bar and transversely offset from the longitudinal axis of said torsion bar for rocking with said outer portion about said longitudinal axis, and means for releasably locking said torsion bar against axial rotation at an adjustable preselected point along the length of said torsion bar inwardly of said outer portion and including a block having a longitudinal bore of a transverse cross section corresponding to that of said torsion bar and slidably engaging said torsion bar and having a tapped transverse bore communicating with said longitudinal bore and a set screw engaging said tapped bore and said torsion bar, and means restricting the rotation of said block.
