EDWVARD K. PATTEN, OF VVHITESBOROUGH, NEW YORK, ASSIGNOR TO THE SEAMAN DRAWER FITTING MACHINE COMPANY, OF MILWAUKEE,

WISCONSIN.

COMBINED CUTTING AND SCOURING DEVICE.

SPECIFICATION forming part of Letters Patent No. 479,332, dated July 19, 1892.

Application filed January 14, 1892 Serial No. 418,035. (No model.)

To all whom, it may concern:

Be it known that I, EDWARD K. PATTEN, of WVhitesborough, in the county of Oneida and State of New York, have invented certain new and useful Improvements in a Combined Cutting and Scouring Device; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to a combined cutting and scouring or sandpapering device for use in the manufacture of furniture or other articles; and it consists in the mechanism hereinafter more fully described, pointed out, and claimed.

Like figures refer to like parts in the two figures of the drawings.

In the accompanying drawings, Figure 1 represents a plan View of what for the purpose of this description I term my improved cutter-head, and Fig. 2 represents a sectional view of the same on line A A.

My cutter consists principally of a disk or plate of metal 1, having suitable hub 2 for the reception of the driving shaft or arbor, which is shown in broken sections at 3, Fig. 2, and which is rigidly fixed thereon. Attached to and projecting from the periphery or disk of plate 1 I provide suitable cutters 4 4 4: 4 4 4c. These cutters are alternately serrated and square-bitted. The cutting-edges of the serrated cutters are set for practical operation at a slightly-greater distance from the center of the disk than the cutting-edges of the fiatbitted cutters. The serrated cutters are placed in the head or disk, projecting beyond the periphery thereof and substantially parallel therewith and having their cutting-edges so arranged as to cut in a plane substantially parallel with the face of the head or disk. The square-bitted cutters, which I for convenience call clearers, are placed in the disk or head, projecting beyond the periphery thereof and having their cutting-edges adapted to cut substantially at right angles to the cut of the serrated cutters. The use of the two kinds of cutters serves to remove all of the material which it is desired should be removed from the article to be operated on at each revolution of the cutter-head,thus avoiding all splinteril'ig and obviating undue friction caused by the use of the head. In the face of the disk 1 I provide a circular groove or depression, as shown at 5, Fig. 2. The outer Wall of this groove 1 preferably construct square with the face of the disk. The inner wall I prefer to construct so that it shall stand at a more or less obtuse angle with the face of the disk, as shown at 6, Fig. 2. Into this groove or depression I introduce a ring 7, of metal, correspondingin general outline to the shape of the groove, but sufficiently reduced in sectional area to allow sufficient space between inner walls of groove and inner surface of ring, as shown at 8 S, Fig. 2, to admit of the introduction of the sand-paper or its equivalent, which is shown at 9, Figs. 1 and 2. I also prefer to so proportion the ring 7 that when in its normal or operating position its lower surface shall not come in contact with the bottom of the groove, as shown at 10 10, Fig. 2.

Ring 7 is removable and is held in place by screw-bolts 11 11 or their equivalent. In ad justing this portion of my device I remove ring 7 from the groove, laying a suitable piece of sand-paper or its equivalent upon the surface of the disk 1. I force ring 7 into groove 5, carrying with it the outer edge of the sandpaper and clam ping it firmly and securely between the opposing surfaces of the ring and groove, as shown at 12 12, Fig. 2. Inserting and tightening the bolts 11 hold the ring and sand-paper firmly in position. The action of the inclined faces of the groove and ring as they are clamped together has the effect of slightly stretching the sand-paper and removing any wrinkles or folds that may have previously existed therein. Suitable packing The purpose of inserting the sand-paper in the cutter-head inside of the cutters is to remove any inequality of surface after the cutters have performed their work upon the article to be operated upon and to leave it with a scoured surface.

The action of my device is as follows: The work to be operated upon is passed across the face of the cutter-head, which is made to revolve at a proper speed. The cutters, being properly adjusted, remove the more prominent asperities of the surface, while the sandpaper or its equivalent smooths and finishes the same, thus performing at one operation and in a cheap and expeditious manner what has heretofore usually been done in two separate and distinct operations.

It is evident that various structural changes could be made in the structure of my device without departing from the spirit of my invention. Hence I do not rigidly confine myself to the specific construction described herein.

My invention refers more particularly to an improvement in a cutter-head for which Letters Patent No. 330,260, dated November 10, 1885, were granted to me, and consists in the sandpapering and scouring device constructed and applied to the face of the head, whereby the material on which the cutter-head operates may be left with a scoured surface.

1. A rotating cutter-head having cuttingspurs in the face of the head, extending substantially parallel therewith and projecting beyond the periphery, and clearing-spurs set substantially at right angles to the cuttingspurs, extending beyond the periphery of the head, in combination with a scouring-surface upon the face of the head within the cutters substantially flush with the face of the cutters, substantially as and for the purposes set forth.

2. A rotating cutter-head having serrated cutting-spurs in the face of the head, extending substantially parallel therewith and projecting beyond the periphery, and clearing spurs set substantially at right angles to the and screws, substantially as and for the purposes set forth.

3. The combination, with a rotating disk mounted upon the end of a shaft, of one or more cutters secured in the face of the disk at right angles with the shaft, extending beyond the periphery of the disk, and one or more clearers at right angles with the out ters, extending beyond the periphery of the disk, and sand-paper or other scouring ma terial upon the face of the disk within the cutters, and clearers substantially flush with the plane of the cutters and adapted to cut and scour a width equal to the diameter of the scouring-material upon the face of the disk, substantially as and for the purposes set forth.

4. In a cutter-head, the combination, with a rotating planer-head, of one or more clearers attached to the head at right angles thereto and projecting beyond its periphery, and one or more cutters attached to the head with their cutting-edges substantially at right angles to the cutting-edges of the clearers, constructed to move simultaneously for the cutting and crosscuttingand clearing the material and adapted to plane a width equal to the diameter of the head and cutters, in combination with sand-paper or other scouring material upon the faceof the head Within the cutters, and ring and screws for securing the sand-paper or scouring-surface to the face of the head, substantially as and for the purposes set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

EDWARD K. PATTEN.
