Description

UNITED STATES PATENT OFFICE.
WILLIAM N. BERKELEY, OF CEDAR RAPIDS, IOWA.
Specification forming part of Letters Patent No. 56,164, dated July 10, 1866.
To all whom it may concern.' j
Beit known that I, WILLIAM N. BERKELEY, of Cedar Rapids, in the county of Linn and State of Iowa, have invented a new and useful Improvement in Tools for Adjusting Lathes to Turn Tapering Shafts; and I do hereby declare and make known that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings and the letters and figures marked thereon, which form part of this specification.
To enable those skilled in the art to under stand how to construct and use my said invention, I will proceed to describe the same with particularity, making reference in so doing to the aforesaid drawings, in which- Figure l represents a plan or top view of Iny invention; Fig. 2, a side or edge view of the same; and Fig. 3 illustrates the manner in which my invention is applied for the purposes specified.
Snnilar letters of reference in the several figures indicate the same parts of my invention.
A represents a strip or plate of metal, of any suitable length, provided with a longitudinal slot, as shown, (marked a.) B B and C C represent, respectively, pairs of arms pivoted together at one end at D D by a screw passing through the aforesaid slot a, by the turningof a nut, upon which said arms may be adj usted and secured in any desired position. E represents screws passing through said slot, between the arms B B and C C, as shown, having suitable cylindrical blocks thereupon, against which the arms aforesaid may rest, thus insurin g the symmetrical adjustment of the arms upon each side of the plate A.
Having described the construction of my d invention, I will now describe the manner Saiwhich it is used in adjusting the lathe as res ai d.
F Grepresent the devices for holding the shaft to be operated upon, (marked H,) one of them, Gr, having a lateral adjustment when desired. The shaft having been arranged in the lathe, a line is described upon the top thereof', as shown at d, in the same vertical plane with the points F Gr supporting the shaft. The tool is then adjusted so that the distance between the points b of the arms B shall equal the diameter of the larger end of the proposed tapering shaft, and the point o of the arms (l shall in like manner measure the diameter of the smaller end of said shaft, while the distance between the points b and c represents the proposed length of the shaft. A straight-edge, I, is then arranged parallel to the line d, before mentioned, at a suitable distance therefrom, being attached in some suitable manner to the tool-carriage of the lathe, when my invention, adjusted as aforesaid, is arranged against the said straightedge, as shown. The adjustable bearing G is then moved toward the tool until the shaft is brought to the position indicated by the dotted line, when it is properly adjusted, and the turning process will produce a shaft of the requiredshape.
This tool may be used also `for a great variety of other purposes, and is a very useful and convenient article for the use of mechanics and machinists generally.
Having described the construction and operation of my invention, I will now specifj7 what I claim and desire to secure by Letters Patent:
1. The combination and arrangement of the plate A, provided with a slot, a, and the arms C B, operating as and for the purposes herein set forth and described.
2. In combination with the above, the employment of the gages or guides E, arranged as and for the purposes specified.
WM. N. BERKELEY.
