SPECIFICATION forming part of Letters Patent No. 737,987, dated September 1, 1903.

Application filed August 23, 1902. Serial No. 120,807. (No model.)

To aZZ whmn it may concern:

Be it known that I, JOSEPH W'ILSON, a citizen of the United States, and a resident of Lathrop, in the county of Clinton and State of Missouri, have invented a new and Improved Boring and Tenoning Machine, of which the following is a full,ciear,and exact description.

The invention relates to portable woodworking machinery; and its object is to provide a newand improved boring and tenoning machine which is simple and durable in construction, very effective in operation, easily applied or removed, and arranged to permit of quickly and accurately boring fellies and other articles and forming tenons on the ends of spokes.

The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.

A ractical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the improvement as applied for forming a tenon on a spoke. Fig. 2 is a plan view of the same. Fig. 3 is a face view of one end of a framesection. Fig. 4 is a like View of the bracket for the feed-lever; and Fig. 5 is a transverse section of the clamping device for fastening the machine to 2. spoke or other support, the section being on the line 5 5 of Fig. l.

The improved boring and tenoning machine is mounted on a frame A, made in sections A and A connected with each other by a bolt 0 to allow of swinging the sections into longitudinal alinement or into an angular position one relative to the other, according to the use made of the machine, as hereinafter more fully described.

The outer end of the frame-section A is formed with a shoe A adapted to engage one side of the spoke D or other article on which the machine is to be used, and in order to hold the frame in position on the article I provide a clamping device consisting, essentially, of a cam-lever E, having a handle E, and having its pivot E mounted'to turn in and slide vertically in guideways A formed or secured on the shoe A Eyebolts F engage the pivot E and extend loosely through the shoe A and through a clip-plate F, engaging the side of the spoke or other article D opposite the one engaged by the shoe A as will be readily understood by reference to Figs. 1 and 5. Nuts F screw on the eyebolts F and abut against the underside ofthe clip-plate F, and springs F are interposed between the clip-plate F and the shoe A so as to turn the pivot E in an inward direction to engage the peripheral surface of the cam-lever E firmly with the outer face of the shoe A Now by swinging the handle E of the cam-lever E into the position shown in Fig. 1 the shoe A and clip-plate F are firmly pressed in contact with opposite sides of the spoke or article D, so as to securely hold the frame-section A in position on the article.

When it is desired to release and disconnect the frame from the spoke D, then the operator swings the handle E over to the left, so as to relieve the shoe A and clip-plate F of pressure and to disengage the same from the spoke or article D to allow of slipping the frame off the end of the spoke.

In the outer end of the frame-section A is formed a bearing A in which is mounted to slide an arm G, carrying the boX G,in which is mounted to slide and to turn the spindle I, provided at its outer end with ahandle J under the control of the operator for turning the spindle I. On theinner end of the spindle I is secured by a set-screw K or other device a tool-carrier K, carrying the tool L for cutting the tenon on the end of the spoke or for drilling a hole in a felly or other article, it being understood that the tool L is shaped corresponding to the intended use thereof. On the tool-carrier K is formed a reduced portion engaged by a shifting collar N, held in the forked end 0 of a feed-lever 0, used for moving the spindle I longitudinally to engage the tool L with the work or to move it from the same. In the lever O is formed an elongated slot 0 engaged by a pivot P of a bracket P, secured by the bolt 0 to the frame at the joint of the, sections A and A as plainly shown in the drawings.

The bracket P has its attaching end in the form of a disk P formed with a transverse slot P (see Fig. 4,) through which the shank of the bolt 0 passes loosely, and on the said disk P is also formed a lug P adapted to engage one of a series of recesses A, formed in the periphery of a disk A at the inner end of the frame-section A. Now by loosening the bolt C the bracket P can be moved transversely, owing to the elongated aperture P to disengage the lug P from a recess A thus allowing of turning the bracket and sections A and A on the bolt 0 to bring the sections into a desired angular position relative one to the other, with the bracket P, however, standing at right angles to the section A When the desired adjustment has been made, the bracket P is moved back, so as to engage the lug P with the registering recess A and then the bolt 0 is screwed up to securely fasten the several parts-that is, the frame-sections and bracketin position.

When the several parts are in the position shown in the drawings, then on the operator turning the handle J a rotary motion is given to the spindle I, tool-carrier K, and tool L, and on the operator imparting a swinging motion to the lever O the spindle I and its parts are fed inwardly, so as to engage the tool L with the article to be workedthat is, as shown in Fig. 1, to form a tenon on the end of the spoke.

When the device is to be used as a boringmachine,the section A of the frame is clamped to a suitable support and the section A and bracket P are adjusted to an angular position relative to the section A. The spindle I is then turned and moved in its bearing J, as above described, by the operator manipulating the handle J and lever O correspondingly.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A boring and tenoning machine,comprising a frame formed of two jointed sections, one of said sections having a recess near the end thereof, cutting mechanism mounted on one of said sections, means mounted contignous to the cutting mechanism and adapted to be moved into engagement with the recessed portion of the frame, whereby the frame-sections may be held in an adjusted position, and a lever connected with the aforesaid means and adapted to be actuated to move the cutting mechanism longitudinally, as set forth.

2. Aboring and tenoning machine,comprising a frame formed of two sections, pivotally connected, whereby an angular adjustment between said sections is attainable, a spindle adj ustably supported by one of said sections, a tool-holder carried by said spindle, a lever for said tool-holder, and means mounted adjacent to the pivotal connection of the frames, and engaging with said lever for holding the frames in any desired angular position relative to each other, substantially as set forth.

3. Aboringandtenoningmachine,comprising a frame formed of sections pivotally connected with each other, a clamping device on one of said sections to secure the frame to the article to be operated on, or to a suitable support, a spindle journaled in the other section of the frame, and provided with a tool-carrier, a bracket held adjustable on the joint of the frame -sections, and provided with means adapted to be moved into and out of engagement with said sections for holding and releasing said sections from relative adjusted positions, a lever fulcrumed on the said bracket and engaging the said feed-spindle to move the latter in the direction of its length, the said lever having an elongated slot engaged by a pivot on the bracket.

4. A boring and tenoning machine provided with a frame made in sections, one of said sections having a series of notches or recesses therein, a bolt connecting the sections, an adjustable bracket engaged by the said bolt, and having a lug adapted to engage one of the notches or recesses in the aforesaid recessed frame-section, and a lever fulcrumed on said bracket, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOSEPH WILSON.
