| Original application 05 Jun., 1901, renewed 23 May, 1904.
Abstract:
My invention relates to steady-rests for steadying the work to be operated upon in a lathe or grinding-machine. The work is usually supported at each end on centers mounted, respectively, in the head and tail stocks of the machine. This old and well-known means of supporting the work at separated points as nearly as possible on the axis of revolution is extremely simple and would be very accurate were there not a lack of rigidity in the work when operated upon, if centers are depended upon alone to hold the work against the pressure of the tool or grinding- wheel, especially if the centers are widely separated or the work is light or the operation upon the same heavy. This is a very serious objection where accuracy is desired.
Claim:
In a steady-rest the combination with a carrier, of work-bearings rigidly mounted in said carrier in different planes, said carrier having separated supports adapted to be mounted on a rigid base and means for adjusting said carrier in either plane.
