WOOD-WORKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 427,158, dated May 6, 1890.

Application filed October 19, 1889. $erial No. 327,486. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM F. COOPER, a citizen of the United States, residing at Dubuque, in the county of Dubuque and State of Iowa, have invented certain new and useful Improvements in Wood-\Vorking Machines; and I do hereby declare the following to be 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, reference being had to the accompanying drawings,'and to letters of reference marked thereon, which form a part of this specification.

This invention pertains to certain new and useful improvements in wood-working machines, having reference more particularly to such as are used for tenoning and chamfering pieces of frame-work, and especially applicable in the manufacture of spokes and like articles.

The invention consists, briefly, of a frame having an adjustable or sliding carriage for carrying the piece of wood and a series of coaxially-arranged adjustable saws and disks or wheels carrying knives and cutting-tools, whereby the operation is completed in the passage of said carriage from one end of its movement to the other,substantially as hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in perspective of my improved ma- Fig. 2 is a detail view of a portion of the carriage, showing a piece of wood as presented to the truing-knives. Fig. 3 is a view showing the tenoning or chamfering disks or wheels and apiece of wood after being acted upon by the latter. Fig. 4 is a view of both such wheels. Fig. 5 is a detail perspective view of the wheel and knives for backing and beveling the tenon.

Referring to the drawings, A designates the main or stationary frame, constructed after any preferred form, and aa sliding or movable carriage having at one end a grooved bar a, running on a vertically-adjustable guide a and at the other end a roller a resting on the upper edge of an adjustable board a of frame a. To carriage A are secured adjustable supports B, upon which the piece of wood is appropriately secured.

O is a shaft resting in suitable journalboxes, and provided at one end with a disk or wheel D, having cutting-knives d, for truing, facing, or straightening the end of the piece of wood to be tenoned, and near the other end of this shaft is a second disk or wheel E, having a conveXed face, and provided with knives e e, for backing or beveling the tenon.

F is a second shaft at right angles to shaft 0, and upon it are secured circular saws G G, capable of adjustment longitudinally of the shaft by any ordinary means, so as to secure the length desired for the piece of wood.

H H are two upper and lower disks or wheels secured upon short shafts h, preferably adjustable horizontally by having their ends secured in depending plates provided with corresponding holes or apertures, as shown at H Fig. 1. These disks or wheels are provided with alternating series of sawteeth h h, chamfering-teeth h 71 and planing-knivesh it for the purpose of finishing the-tenon end to the proper requirements. It will be seen that the teeth and knives of these disks or wheels are correspondingly arranged, so that they will act conjointly upon the piece of wood undergoing operation.

Upon shafts h h are secured band-pulleys -i 2', around which is passed a crossed belt 2'', so that disks H H move in the same direction, and upon the shaft of the lower disk or wheel is a second pulley 2' with which engages a belt I, passed over an upper pulley 11 and a lower wheel J on a shaft j. A second wheel j is also secured on this shaft, and motion is I imparted from a driving-belt f passed therearound. Further power is obtained through belts K K K said belts K and K being passed, respectively, around pulleys 70 70' on shafts C and F, whereby motion is imparted thereto.

The operation of my invention is as follows: The piece of wood to be operated upon is first secured upon supports B of carriage a, which is then at its starting-point m, Fig. 1. The carriage is moved by the hand of the operator,

and the end to be tenoned is first subjected to the action of the'knives of disk or wheel D for truing thereof, and after this is accomplished further movement of the carriage presents both ends of the piece of wood to the action of the circular saws G, whereby the same is reduced to the proper length. The next operation is that effected by the disks or wheels II II, whereby the end of the piece of wood is tenoned and chamfered by the action of the saw-teeth, chamfering-teeth, and the planing-knives. The final step of the operation is effected by the presentation of the tenoned end to the action of the knives of the disk or wheel E, whereby the backing or beveling of the tenon is accomplished, and the carriage has then reached the limit of its move ment, after which it is returned to its starting-point for further operation. Thus it will be seen that the entire process or operation of truing, sawing, tenoning, chamfering, and backing of a piece of wood is accomplished in the single passage of the carriage from one end of its movement to the other. It will also be observed that by rendering the circular saws adjustable on their shaft and making ad justable horizontally the shafts of the disks or wheels 11 II the piece of wood or spoke can be reduced to any" desired length and the tenons and chamfers formed therein at different de grees.

I claim as my invention.

1. In a wood-working machine, the combination, with the sliding frame for carrying a piece of wood, of a disk or wheel having knives for t-ruing one end of such piece of wood, parallel saws for sawing the ends thereof, two disks or wheels for simultaneously tenoning and chamfering said end of such piece of wood, and a disk or wheel having knives for backing said end, substantially as set forth.

2. In a wood-working machine, the combination, with the sliding frame for carrying a piece of wood, of a disk or wheel having knives for truing one end of such piece of wood, parallel rotary saws, together with their shaft, upon which they are adjustable, two disks or wheels for tenoning and chamfering said end of said piece of wood and having their shafts adjustable in bearings, and a disk or wheel having knives for backin g said end, substantially as set forth.

3. In a wood-working machine, the combination of the shaft 0, having disks or wheels at or nearits opposite ends provided with cutting-knives, the parallel saws arranged adjacent to one of said disks or wheels, the disks or wheels for chamfering a piece of wood located between said saws and the other disk or wheel on shaft C, and the sliding frame having supports for such piece of wood, substantially as set forth.

l. In a wood-working machine, the combination of the disks or wheels D E, having cutting-knives and located at opposite ends of the supporting-frames, the parallel circular saws adjacent to said disk or wheel D, and the upper and lower disks or wheels having saw and chamfering teeth and planing-knives and located between said saws and the disk or wheel E and the sliding carriage, substantially as set forth.

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

. WILLIAM F. COOPER.
