WOOD-WORKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 362,993, dated May 17, 1887.

Application filed July 9, 1886. Serial No. 207,617.

To (tZZ whom it may concern.-

Beit known that I, DELrHIs PIOARD, a citizen of the Dominion of Canada, residing in the city and district of llilontreal, and Province of Quebec, Canada, have invented certain new and useful Improvements in WVood- \Vorking Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Letters Patent have been granted for this invention in Canada, which bear date June 2, 1886, and are numbered 24,213.

This invention relates to wood-working machines; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed, whereby a novel machine is produced which can be used for sawing wood, making moldings, pin-holes, pins, pin slots, and may be put to a variety of other uses by changing the cutters used in it.

In the drawings, Figure l is a plan View from above of the machine. Fig. 2 is also a plan view from above, but has the saw-table raised,exposing the mechanism ofthe machine. Fig. 3 is an end view of the machine; and Figs. 4 to 12, inclusive, show views of various tools and cutters for use in connection with the machine.

The machine consists, mainly, of two end frames, X and Y, united by cross-braces. A saw-table, G-,.is secured to the ends of the frames by the hinges H, so that it may be thrown over out of the way when not required in use. This table is provided with a slot, 0, for the saw D, which is mounted upon the end of shaft L, and is indicated by the dotted line in Fig. 3.

A is the saw-gage, having slot F, and secured to the table by the screw E, and B is the feeder. These parts are like those ordinarily used.

The table can be made in pieces, and that part ofit indicated by the dotted lines in Fig. 2 can be removed entirely, if desired, to be out of the way when the machine is used for other purposes.

L is the saw-shaft journaled in bearings secured to the frames, and provided with the driving-pulley S and spur-wheel T. The said spur-wheel is secured to the shaft L by the key (No model.) Patented in Canada June 2, 1880, No. 24,213.

4), which permits the wheel to he slid along the shaft and placed out of gear with the wheel V on shaft N when the machine is used for sawing. A hole, 0, is formed in the end of shaft L for the insertion of the stems of the cutters. The shaft N is journaled in bearings and revolves parallel with the shaft L, being connected to it by the said wheels T and W. A hole, 9, is formed clear through the shaft N, and an enlarged hole, f, is formed in the enlarged portion (2 at one end of it. This hole f is also for the reception of the stems of the cutters.

M is a third shaft, journaled in bearings scoured to the frame of the machine, and pro vided with the rotary feed-roll O, secured on one end, and the driving-pulley 1, running loose upon the other end of it.

Q is a clutch splincd to shaft M, and provided with the rod R, for throwing it in and out of gear with the clutch-jaw formed on the hub of the pulley I. The end of shalt M, to which the feed-roll is secured, is allowed to have a slight vertical play in its bearing, and the shaft is pressed downward by the weight 8 upon lever '10, which is pivotally connected to the frame and to the rod a, the upper end of which is provided with an eye or hook which engages with shaft M.

Dovetailed guides i are secured to frame X for the flangej of the end table, J, to slide on, and h is a slot in the said frame for the nut of the clamping-screw k to slide in, so that the end table may be secured at any desired elevation. The end table, J, is provided with the l-shapcd slot Z for the vise shown in Fig. 4, which is of ordinary construction, and may be used for holding work. Stems o are relnovably placed in holes in the table J, and carry springs m, so that work can be secured on the table by placing it between the said springs and the flange j. \Vhen the table G is thrown over, the machine can be used for making moldings by sliding the tool shown in Fig. 5 onto the end of shaft L in place of the saw. The piece of wood'to be operated 011 is placed on table J between springs m and the llangej, and one end of it is thrust under the revolving feed-roll O, which draws it along under the revolving cutter, being caused to bear upon it by the weighted lever w.

In order to make round pins from square through the other end of the hollow shaft N after being cut to a circular form.

To make holes for pins, the attachment shown in Fig. 11 is secured to the end table, and the tool shown in Fig. 7 is secured in hole f of shaft N.

The cutter shown in Fig. 12 is used for making the tops of T-slots, and the cutters shown in Figs. 9 and 10 are usedfor making the cavities for the insertion of bedstead-irons.

Many other cutters can be used in. the machine, which is useful for a great variety of purposes, the cutters shown being only intended to show the principle of its action.

What I claim is In a wood-working machine, the combination of a supporting-frame, a saw-table hinged to the frame, a saw-shaft journaled in bearings secured to the frame and having the end hole, 0, the vertically-adjustable end table provided with a screw for holding it and springguides for holding the work, the shaft M, journaled parallel with the sawshaft and capable of a vertical movement at one end, the revolving feed-roll O, secured upon the said shaft, a weight for pressing the feed-roll onto the work, the hollow shaft N, having the enlarged hole f in one end for cutters, and the wheels W and T, connecting the shafts N and L, so that they revolve parallel to each other, substantially as and for the purpose set forth.

In testimony whereof I have affixed my sigmature in presence of 'the two subscribing wito In presence of-- PHIDYME P. BOURQUE, A. HOME.
