Abstract
Abstract A work support for a centerless grinder or the like comprises an elongated floor-supported guide tube adapted to extend along beneath a work piece to be machined in the grinder with a plurality of V-shaped supports arranged on the guide tube in spaced relation therealong and having at their ends a pair of work supporting booty rollers mounted in confronting cooperative work supporting relation on opposite sides of the work to be supported with the axes of the rollers skewed to the axis of the work, each such roller having a booty axle having angularly related roller receiving and axle mounting portions with the latter supported on the V-shaped arms to extend parallel to the axis of the work to be supported, and with means supporting the axle mounting portion on the arms for adjustable rotation about their axes and for locking the axles in adjusted rotated positions, thereby providing for adjustment of the skew angle of the booty rollers relative to the work to be supported.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
197 words
In a centerless grinder work support having an elongated floor supported guide tube adapted to extend along beneath a work piece to be machined in the grinder and with a plurality of upwardly extending V-shaped supports arranged on the guide tube in spaced relation therealong with the arms of the V disposed on opposite sides of the work to be supported, a pair of work supporting booty rollers mounted in confronting cooperative work supporting relation on the arms of each V-shaped support with the axes of the rollers skewed to the axis of the work to be supported, an axle for each booty roller, said axle comprising integral opposite end portions, one being a booty roller receiving portion and the other an axle mounting portion, said portions being arranged in end-to-end angled relation, and means supporting said axle mounting portions for adjustable rotation on the arms of the V-shaped supports about axes extending parallel to the axis of the work to be supported and for locking said axle mounting portions in fixed positions on such arms, whereby the skew angle of the booty roller receiving portion may be adjustably fixed relative to the work to be supported.
Claim 2
Dependent Claim
197 words
In a centerless grinder work support having an elongated floor supported guide tube adapted to extend along beneath a work piece to be machined in the grinder and with a plurality of upwardly extending V-shaped supports arranged on the guide tube in spaced relation therealong with the arms of the V disposed on opposite sides of the work to be supported, a pair of work supporting booty rollers mounted in confronting cooperative work supporting relation on the arms of each V-shaped support with the axes of the rollers skewed to the axis of the work to be supported, an axle for each booty roller, said axle comprising integral opposite end portions, one being a booty roller receiving portion and the other an axle mounting portion, said portions being arranged in end-to-end angled relation, and means supporting said axle mounting portions for adjustable rotation on the arms of the V-shaped supports about axes extending parallel to the axis of the work to be supported and for locking said axle mounting portions in fixed positions on such arms, whereby the skew angle of the booty roller receiving portion may be adjustably fixed relative to the work to be supported.
Claim 3
Dependent Claim
74 words
The invention defined by claim 1 characterized in that said means includes an aperture extending through each arm of the V-shaped supports through which the axle mounting portion is extended, said axle mounting portion includes a shoulder adapted to overlie one side of the arm of the V-shaped support adjacent said aperture and nut means threadedly engaged on the axle mounting portion for tightening against the opposite side of the arm adjacent the aperture.
Claim 4
Dependent Claim
35 words
The invention defined by claim 2 characterized in that said shoulder has wrench engaging means adapted to permit holding of the axle mounting portion in a fixed rotated position during tightening of said nut means.
