GEORGE J. GOODHUE, OF STEVENS POINT, ASSIGNOROF ONE-HALF TO HARVEY M. WVADLEIGH, OF HATLEY, WISCONSIN.

WOOD-WORKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 374,671, dated December 13, 1887.

Application filed May 2, 1887. Serial No. 236,830.

To all whom it may concern Be it known that I, GEORGE J. GOODHUE, of Stevens Point, in the county ofPortage, and

in the State of Wisconsin, have invented certain new and useful Improvements in Wood- Working Machines; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to wood-working ma,- chines, being specially designed for shaping the'ends of the caps that form part of the timber structure for mines, set forth in Letters Patent No. 358,261, dated February22, 1887; and it consists in certain peculiarities of construction and combination of parts, to be hereinafter described with reference to the accompanying drawings, and subsequently claimed.

In the drawings, Figure 1 represents an elevation of a machine constructed according to myinvention; Fig. 2, avertical transverse section taken on line m0 of Fig. 1; Fig. 3, a similar view taken on line 1 y,'Fig. 2; Fig. 4, a detail view of the dogs-and means for adjusting the same, and Fig. 5 an end view of the pro duct of my machine.

Referring by letter to the drawings, A A represent horizontal timbers, each of which is provided with atrack, B, for the wheels 0. of a carriage, D, and to the ends of this carriage are secured guides E for flanged plates F, cari'ying dogs G. Each of the plates F has bolted or otherwise suitably secured to the under side thereof a screw-threaded bearing, G, for the screw-threaded end of a rod, H, and by refer ring to Fig. 4 it will be seen that the threads on one end of said rod are opposite to those on the other end thereof.

Fast on the rod H is a gear-wheel, I, that meshes with a pinion, J, on a shaft, J, mounted on the carriage D and provided with a crank, J as best illustrated in Fig. 1. The carriage D has secured thereto, on one side thereof, a rack, K, that engages a pinion, L, on a vertical shaft, L, and secured to the upper end of said shaft is ahand-wheel, L Opposite each end of the carriage D are vertical posts M M, each of which has secured thereto a bearing, N, for a horizontal shaft, 0, and to one end of this shaft is fixed a drive-pulley, P.

Mounted on each shaft 0, between the posts M M, are cylindrical heads Q Q, carrying a (N0 model.)

series of radial saws, a, and a series of longitudinal knives, b, and interposed between said heads is another head,R, carrying knives c, as best illustrated in Fig. 2, the latter head being of much less diameter than the ones Q Q.

The timber to be operated upon is rolled along on skids S to the carriage D, and then raised up to the elevation shown in Fig. 1.

The crank J is now operated to communicate motion to the rod through the medium of the pinion J and gear-wheel I, and thus the dogs G are caused to approach and engage the ends of said timber, whereby the latter is held in its elevated position. I

By operating the hand-wheel L-in either direction the carriage D is caused to move toward one pair of the heads Q. The timber comes first into contact with the saws a on the heads, said saws being slightly in advance of 0 into contact with each other the knives c on the head R come into play to chip outa concave recess, 01, in the end of the timber at right angles to the tongue 61.. Vhen one end of the timber has been completed, a reverse movement is given to the carriage to bring the other end of said timber in contact with the saws and knives on the opposite set of heads, whereby a similar result is obtained. Both ends of the timber having been shaped, the carriage is run back to the position shown in Fig. 1, the dogs released from said timber, and the latter rolled away from the machine.

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

1. In a wood-working machine, the combination of a reciprocative carriage with cylindrical heads arranged in pairs upon a revoluble shaft and provided with radial saws and longitudinal knives, and another cutter-head of less diameter interposed between the firstnamed heads, substantially as and for the purpose set forth.

2. In a wood-working machine, the combi- ICG pose set forth.

3. In a wood-working machine, the combination of a reciprocating carriage, dogs arranged on the carriage at the ends thereof, a horizontal rod having its ends screw-threaded in opposition to each other and connected to the dogs, a gear-wheel fast on the rod, a pinion arranged on the carriage to mesh with the r 5 gear-wheel, and suitable means for operating the pinion, substantially as set forth.

In testimony that I claim theforegoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of Wisconsin, 20

in the presence of two witnesses.

GEORGE I. GOODHUE.
