GEORGE GRAY, JR., OF CINCINNATI, OHIO, ASSIGNOR, BY MESNE ASSIGNMENT, TO
` HIMSELF, AND ALEXANDER GORDON .Y
Letters Patent No. 91,841, dated June 29, 1869.
The Schedule referredto :in these Letters Patent and making part of the same.
To all whom it may concern:
Be it known that I, GEORGE A. GRAY, Jr., of Gin.- cinnati, Hamilton county, State of Ohio, have invented a certain new and useful Improvement in Mandrels for Facing Nuts; and I do hereby declare the following to be a sniciently full, clear, and exact description, to enable one skilled iu the art to which my invention appertains, to make and use it, reference being had to the accompanying drawings, which form a part of this speciiication. v
My invention relates to that class of, nut-mandrels in which the shoulder or face against which the nut is screwed adapts itself to the face of the nut; and consists of a spherically-cnpped washer, constructed to fit a spherically-formed shoulder of the mandrel. v
1n the accompanying drawings- Figure l is a perspective view of a mandrel with washer detached.
Figure 2 is a longitudinal section of mandrel-washer and nut tobe faced, in position.
A is the mandrel, which is screw-threaded at a to receive the nut. It may be provided with conical indeutations a. at each end, so that it can be worked between the centres of the lathe, or it may beturned tapering at the large end. and driven into the lathe-spindle.
The shoulder al of the mandrel is spherically formed, as shown.
A washer, B, constructed with a plain straight face on one side, and spherically cupped or dished on the other, iits against and matches the shoulder a". The nut to be faced is screwed against this Washer, as shown in iig. 2, and no matter what may be the plane of the face of the nut with relation to the axis of the threaded mandrel, the washer rolls over' the shoulder andadapts itself to the nut. Y
The purpose of this device is to admit of a crooked nut being forced tightly against the shoulder or face of the washer to a solid bearing without being canted over on its thread.
I claim herein as new, and of my invention#- The construction and arrangement, with reference to each other, in thetool herein described, ofthe threaded portion a, sphericalshoulder a", and washer B, asvand for the purpose specified.
In testimony of which invention, I hereunto set my hand.
G. A. GRAY, JR.
