CUTTER-HEAD.

srEcIFIcATIoN forming part of Letters Patent No. 668,734, dated February 26, 1901.

Application tied May s, 1900. serai no. 15,918. (No mais.)

To a/ZZ whom it may concern:

Be it known that I, HARRISON C. HosIER, a Icitizen of the United States, residing at Washington Court-House, in the county of Fayette and State of Ohio, have invented new and useful Improvements in Cutter-Heads, of which the following is a specification.

My invention relates to improvements in cutter-heads, and pertains to a cutter-head specially constructed and adapted to cut out Cobble-seats for chairs, all of which will be fully described hereinafter.

Heretofore in cutting out cobble-seats for chairs the circle has been cut out bya scrollsaw and the rabbet for receiving the cobble afterward made on a former, which is a tedious and slow method, requiring the seat to pass through several hands before it is ready to receive the cobble or seat.

The object of my invention is to construct a cutter-head which will by a single operation cut ont the circle of the seat and form the rabbet for the cobble or seat, which enables me to rapidly and easily form Cobble-seats and enabling me to thereby reduce considerably the cost of manufacture of seats of that type.

In the accompanying drawings, Figure 1 is a perspective view of a cutter-head embodying my invention. Fig. 2 is a transverse sectional vieW of the cutter-head and the seat being operated upon. Fig. 3 is a top plan view of the seat-blank composed of rightangle bars from which cobble-seats are usually cut. Fig. 4 is a detached perspective view of one of the planes J.

Referring now to the drawings, A is the head, disk, or body portion of my cutter-head, which is provided at its periphery with one or more projecting cutters or saws B (preferably saws) of the construction here shown. These cutters B, which, as before stated, are preferably ofthe saw type, serve the function of cutting the circle C of the seat. Preferably these cutters B are short, as here shown, and the periphery of the body portion A provided with inwardly extending plane receiving openings or recesses D, the rear Wall E of the said recesses being inclined to receive a suitable plane G, which has its cutting edge a projecting below the lower or outer face of the body A and adapted to plane away that por# tion of the bars H of the seat (shown in Fig. 3) lying between the cutters B and the inner edges of the bars H. These planes E therefore Will be of a width equal to and preferably slightly in excess of thewidth or distance of the bars H between the groove cut by the cutters B and their inner edges. From this it will be noted that the cutters B cut the circle, while the planes E remove that portion of the bars H lying inside of the groove out by the said cutters.

While I prefer to use short cutters B for cutting the circleV in combination with the planes E,as before stated, yet it will be readily understood that the planes E may be omitted and the cutters B made of a sufficient length to extend or cut entirely through the thickness of the bars H. In this event there will be no necessity for the planes E to remove any portion of the bars H, as before explained.

The l'abbet I for receiving the cobble for the seat portion and also the groove b, which is situated at the outer edge of the rabbet I,' are formed by means of the planes J, whichare supported upon laterally-projecting arms or members K, and which, as here shown, project beyond the periphery of the body A, or in the event of the omission of the planes E and the 'use alone of long Glitters B, projecting beyond the cutters B for planing out the rabbet I. The groove b is cut by the cutters L, which are attached to the ends of the arms or projecting members J, and the groove is smoothed by the right-angle knife d, formed upon the outer edge or edges of the planes J.

While I here show a plurality of planes and cutters, it will be understood that one plane and one cutter can be used; but by using a plurality of these members I am able to more rapidly form the seat.

The bars H (or the blank from which the seat is to be formed) may be held in any suitable clamp, and the cutter-head will be secured to a suitable shaft M. The cutter-head may be supported in either a vertical or a horizontal position, and the blank may be lnoved toward the cutter-head or the cutterhead toward the blank for the purpose of forming the seat. I do not here show any means for moving either the blank from which the seat is cut or the cutter-head, as the means IOO necessary for accomplishing this are old and well known and form no part of my present invention.

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

1. A cu tier-head comprisinga disk, a circlecutter projecting from the under face of the disk and extending in a direction parallel the axis thereof, and a plane carried by the disk projecting beyond the said circle-cutter and situated in a plane in rear of the said circlecutter, substantially as described.

2. A cutter-head com prising a circular disk having a circle-cutter projecting from the periphery thereof, and in a direction parallel the axis thereof, and a plane projecting from the opposite side of the said disk beyond the said circle-cutter and situated in a plane in rear of the cutting edge of the circle-cutter, substantially as described.

A cutter-head comprising a circular disk having a circle-cutter projecting from its periphery in a direction parallel the axis of the disk, the said disk having radially-projecting plane-supporters at the opposite side from the cutting edge of the circle-cutter, planes carried by the said plane-Supporters, the supporters and the planes projecting beyond the circle-cutter, substantially as described.

4. A cutter-head comprising a circular disk having a circular cutter projecting from its periphery in a direction parallel the axis of the disk, the said disk having radially-projecting plane-supporters at the opposite side from the cutting edge of the circle-cutter, planes carried by the said plane-supporters, the supporters and the planes projecting beyond the ci rele-cutter, and groove-cutters carried by the plane-supporters and situated at a point inrear of the circle-cutters, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

HARRISON C. HOSIER.
