MACHINE FOR BORING TENONS.

SPECIFICATION forming part of Letters Patent No. 293,880, dated February 19, 1884}.

Application tiled December 527, 1883. (No model.) I

T to whom it may concern: 7

Be it known that I, WILLIAM W. HosLER, a citizen of the United States of America, residing at Petoskey, in the county of Emmet and State of Michigan, have invented certain new and' useful Improvements in Machines for Forming Tenons on Spokes and Boring and Drilling, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has relation to improvements in machines for forming tenons and drilling and boring purposes, and is available for outwheel-spokes.

ting tenons on the ends of wheel-spokes when in their hub, or application to a work-benchwhen the object to be operated on is held thereon; and it consists of the combination and arrangement of parts, substantially as hereinafter fully set forth and claimed.

In the accompanying drawings, Figure 1 is a side view of my improved tenoning and boring and drilling machine as applied to one of its usesth,e forming tenons on the ends of Fig. 2 is an enlarged detail view, partly in section; and Figs. 3 and 4 are also views in detail thereof.

In the organization of my invention I employ a stock or brace, A, the greater length or portion of which is straight, while at one end it is curveddownwardly and provided thereat with a cylinder or box, a, within which is contained a sleeve, 0. The latter is confined in the box or cylinder, as against endwise movement, by an inwardly-projecting annular flange, 1), formed at the outer end of said cylinder, and by an apertured plate, 12, arranged at the opposite end of said cylinder or box and bolted at'its upper end to the stock A.

B is the tool or chuck holder spindle, pass ing through the sleeve a and through the end plate, b, and the outer end of the box or cylinder a, the outer end of said spindle having a handle or crank, B, for turning the same, while its opposite end has a chuck or tool holder, 0, applied thereto,'said holder being sleeved and connected to the spindle by a set or holding screw, 0, extending through its sleeve and bearing against the spindle. The outer flared end is also provided witha set or holding screw, 0 to secure the tool or chuck designed to be held therein, to effect the forming of a tenon,- or for drilling or boring purposes, as may be demanded. In order to support theextreme inner end of the stock A, it

is provided thereat with a rest which consists of a straight upright bar, 0, provided with a foot, 0. Said bar 0 is passed through a vertical slot, d, in the stock A, and is designed to be held therein by a set or holding screw, (1, said foot 0 thereof resting upon a spoke, as

seen in Fig. l, to support or retain properly in position that end of the stock.

D is a lever pivoted to, and also serving as q a support for, the stock A, its lower end resting on the floor, and being connected, near its upper end, to the stock A, preferably by a staple or bail, e, and a pivotal bolt or pin, 6, said staple or bail embracing the stock and fastened to the lever, while the pivotal pin or ing suitably connected to the lever, the rest 0 is placed upon the spoke, and the lever D is disposed in an upright position contiguously to the spoke, and moved so as to bring the tool or-chuck into contact with the spoke, and there held. By now turning the handle B of the spindle B, it is evident that the tool will be rotated and be caused to form a tenon on the spoke. As the operation of cutting the spoke continues, the tool or chuck is fed to its work by moviug, in the direction of cutting, the lever D, which operation is continued until the formation of the tenon is completed. It is obvious that this machine can be adapted as well for drilling or boring purposes. I

\ Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a machine forforining tenons on spokes, the combination ofthe stock A, having one end curved downwardly, to which is secured cylstock A, and strap E for securing the parts to the wheel-hub, substantially as shown and described.

3. A tenon-boring machine consisting of a stock or brace, a ehucleholder comprising a spindle operated by a crank and secured to the stock by plate 1), bar 0, having foot 0, lever D, and strap E, substantially as shoivn, and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.

\VILLIAM \V. HOSLER.
