WILLIAM L. STODDARD, OF ELVASTON, ILLINOIS.
HO'LLOW AUGER.
SPECIFICATION forming part of Letters Patent No. 270,856, dated January 16, 1883.
Application filed July 18, 1881. (No model.)
To all whom it may concern:
Be it known that 1, WILLIAM L. STODDARD, a citizen of the United States, residing at Elvaston, Hancock county, Illinois, have invented a new and useful Improvement in a Hollow Auger, Ten on-Outter, or Turning-Tool, which is made substantially as set forth hereinafter, referring to the accompanying drawings, in which Figure 1 shows a side view, partly in section, of the tool. Fig. 2 shows a top view of part of same. Fig.3 is a bottom view of part or same. Fig. 4 is a cross-section, as shown in Fig. 2 by dotted line.
This invention relates to hollow angers or turning-tools designed for cutting tenons on the ends of wheel-spokes and other similar uses; and it consists in theimproved features substantiallv as hereinafter shown and set forth.
Two plates, A A, are connected and held together by blocks B B, screws 0 G O C, and pivot D. Plates H H, between plates A A, have block D between them, and are also held by pivot D, forming a hinge, on which they are movable to the positions shown by full and dotted lines. These two sets of plates are curved opposite each other in such a way as to tit onto opposite sides of circles K or K, as shown, or any circle intermediate, by turning on pivot D. Their outer ends are held by setscrews L L, arranged to hold them-at any point. The screws are held in plates H H and slide in solts M in plates A A for adjustment. The plate A extendsbackward and turns up to term a hand-crank, P,'bearing a top, P, like a bit-stock, so that it may be turned in a like way about the circleK or K; or the plate H, instead, bears this bit-stocklike handle when preferred. WVhen it is desired the stock-handle is connected with a plate on top of plate A, and held in a like manner by pivot D and by-screw H, and arranged to pivot over the center of whatever center the plates below are set to. This plate, when desired, has a hole coincident with such circle, but, when desired, has instead a shank attached above this circle, to which an ordinary bit-stock can be connected instead of the crank-handle shown.
The cutter E is borne on block B,or on a like block borne by plates H H, and is held by the set-screws F F, which are adjustable in slots in cutter E, so as to cut any size shaving from a tenon or part in circle K or K to the limit allowed by set-screws L L, so as to form a teuon or rounded part on it. The cutter is ad- A cut started at top and run down till a full length of tenon is cut. The cutter E is bent up at its end below plate A to cut a shoulder and separate theshaving cut at its edge. The cutter ltis set into the side of plate A for this purpose, and when desired the bend in E is omitted.
I claim 1. In a hollow anger or turning-tool, the part A, hearing a cutter and a curved guidesurface, the part H, bearing a curved guide- Surface, and a hinge connecting said parts, having its pivot parallel with the cutter, combined with a slotand set-screw borne by the two parts, adapted to adjust and hold them so the cutter may cut around different-sized fixed circles between said parts.
2. The combination of two guide-parts, H H, made separately adjustable and arranged to act upon one side of a tenon or circle, with cutter E, borne by part A, ha ving curved guidesurt'aces arranged to act against the other side of such tenon or circle, and having pivot-hinge and adjustable holder with each of said guideparts H B, so that the instrument can be set to out either a straight or taper teuon.
