CUTTER-HEAD FOR CUTTING 0R TRlMlillNG GORES OF BARREL-BLANKS.

SPECIFICATIGN forming part of Letters Patent No. 389,006, dated September 4:, 1828,

Application filed May 3, 1858. Serial No, 2117M.

To all? whom, it may concern.-

Be it known that 1, JOHN W. PnrLP, a citizen ofthe United States, residing at Humboldt, Gibson county, in the State of Tennessee, have invented new and useful Improvements in Cutter-Heads for Cutting or Trimming Gores of Barrel-Blanks, of which the following isa specification.

My invention relates to n1 ans for forming the gorcs in the edges of thin sheets of wood cut to form blanks for making barrels. Hitherto the gore-s or such veneer blanks have been produced in the operation of producing the blanks, and in the seasoning of the blank the gored parts are liable to change their shape by reason of the warping or uneven contraction of the sheet in drying, and thereby change the form of the gores and put their edges out of true, and thus render the blank unfit for use without the rot-rimming and trning of the gore-edges to form perfect joints.

My invention is directed to the production of a cutter-head for goring seasoned veneer blanks or for trimming the gores ofsuch blanks; and the objects of my improvementare to form such gores or to trim the edges of gores already formed, so that when the sheet is bent to form the barrel the gore-edges will form a perfect joint; to provide a cutter-head having cutters arranged to produce ll-shaped gores; to provide detachable cutters for the purpose of sharpening and renewing them, and to provide an arrangement of cutters that will act at the circumference and upon both faces of a disk in lines extending tangentially to the hub of the disk, so that the cutters only have contact with the edges of the gorcs to a point for giving a close joint. The cutter-blades are thickest at their cutting-edges, so that they will cut themselves free as they extend into the sheet, while the point of each blade is formed with an oblique chisel-edge having its point standing away from the disk to terminate the gore with a sharp angle. For this purpose the sides of the cutter-head taper from the hub nearly to a feather-edge, so that the points of all the cutters of each head will meet in the same plane in a line which determines the angle of the gore. The teeth of each cutter-blade are beveled inward, so that their outer faces will present sharp edges to (No model.)

the edges of the gorcs. The tool or device by means of which this gore cutting or trimming is done is shown in the accompanying drawings, which'form a part of this specification, and in which- Figure 1 is a top plan view of a part of a gang of the cutter-heads,showing them in position with relation to a sheet or blank being gored. Fig. 2 is a side view of one of the cutter heads or disks. Fig. 3 is adiainetricnl sectional view of the same. Fig. 4 is a sectional view showing the transverse form of the cutter-blade. Figv 5 is a perspective dctail view of one of the cutter strips or blades detached from the disk. Fig. ii is an enlarged sectional detail showing the bcveling of the cutter-points and their meeting in the same plane to give a sharp angle to the gore.

In the drawings, the numeral 1 indicates a circular disk, which is ground or otherwise shaped to taper i n thickness to nearly a featheredge. It has a central eye, 2, and hubbcd parts 3, by which it is mounted and secured upon a shaft. Gutters or blades are secured upon the faces of the disk or head,thecuttingedges of the said blades being tangential to the peripheries of the collar-bubs 3 and the blades being secured atequal spaces apart and alternating upon opposite sides. The inner ends of the blades or cutters form seats 5, which fit upon the peripheries of the eye-collars 3, and the outer ends of the blades project a distance beyond the periphery of the disk or head, the ends projecting sufficiently far to cause them to be in one circular line and plane concentric with the disk, the ends being in clined toward each other by the tapering sides of the disk. The cutters or blades are removably securcd,so as to project from the faces of the disk, by means of screws 6, having their heads countersunk in the blades, and the latter are preferably serrated or sawtoothed, and the edges of the teeth being filed or sharp cued with the bevel Q facing the disk, as shown in Figs. 4 and 5, the teeth having thus the so-cailcd briar-tooth form, and being capable of cutting at the outer side or edge only. The serrated or toothed edges of the cutters arc thicker than the rear edges, as illustrated in Fig. 4, so that the cutters or blades will cut themselves free when passing through wood, and the outer teeth of the cutters or blades are filed to a sharp point, so that they will cut into a sharp angle or point when in operation, the points being preferably sharpcued to form an oblique chiseledge, 11, havlug its point at the outer side of the cutter or blade,0r at the side facing away from the disk, so that the points of all the cutters of each head will revolve in the same plane,as seen in Fig. 6.

It will be seen that when a disk provided with these cutters or blades is revolved the sharp edges-of the inwardly-beveled teeth will cut and trim the edges of the gore and the ob lique chisel-points of the cutters will cut and trim the inner angle of the gore to a perfect point.

All the gores in abarrel-blank may be consecutively cutor trimmed by one disk and out ters, or a gang of cutter heads or disks may be secured upon a shaft, 12, .as shown in Fig. 1, the cutter-heads being snitablyspaeed by washers 0r si milar means,13, when all the gores may be cut or trimmed equally at one operation, the blank being fed and held to the cutter-heads in any suitable way. In Fig. 2, A indicates the line of the table in which the cutter-head is mounted.

The disk or head will not be worn during use, as all wear will be taken up by the cutters or blades, which only come in contact with the work, and these cutters will cut themselves free of the work by their being shaped thicker at the toothed edges than at the rear edges, so that there will be comparatively little friction between the cutters and the work.

On account of the blades or cutters being secured tangential to the hub or washers they will have a downward cut, so that they will practically saw or shear the edges of the gore, having no chopping motion, which would exist if the cutters or blades were secured radially upon the disk, aud as the ends project beyond the periphery of the disk and converge into one circular line around and beyond the periphery of the disk the entire edges of the gore will be trimmed and a fine angle or point formed at the inner end of the gore.

By having the cutters or blades removable they may be easily sharpened or replaced, and one disk or head may do duty with a comparatively large number of renewed cutters or blades.

Having thus drscribed my invention, I claim- 1. A cutter-head for cutting or trimming the edges of the gores of barrel-blanks, consisting ofa circular disk tapering on its opposite sides toward its periphery, having cutters or blades on each side inclining toward each other beyond the disk, for the purpose stated.

2. A cutter-head for cutting the gores of barrel-blanks, consisting of a circular disk tapering toward the periphery, and the cutters or blades arranged in lines tangential to a concentric circle and inclining toward each other be; on d the disk, for the purpose stated.

3. In a cutter-head for cutting or trimming the edges of the gores of barrel-blanks, the combination ofa circular disk tapering toward the periphery, with cutters or blades secured upon the tapering faces and projecting beyond the periphery, with their outer ends in concentricline beyond the periphery, as shown, and for the purpose specified.

4. In a cutter-head for cutting or trimming the edges of the gores of barrel-blanks, the combination of a circular disk or head tapering toward the periphery, with cutters or blades secured upon the faces of the disk or head and having the cutting-edges thicker than the rear edges, as shown, and for the purpose specified.

5. In a cutter-head for cutting or trimming the edges of the go res of barrel-blanks, cutters or blades having their cutting-edges thicker than their rear edges and formed with briarteeth beveled toward the inner side, or side facing the head, as shown and described.

6. In a cutter-head for cutting or trimming the edges of the gores of barrel-blanks, the combination of a circular disk or head tapering toward the periphery, with cutters or blades secured to the faces of the disk and formed with briar-teeth beveled toward the inner sides facing the disk, as shown and described.

7. In a cutter-head for cutting or trimming the edges of the gores of barrel-blanks, a cutter or blade having its cutting-edge formed with briar-teeth beveled toward theinner side, and

having the outer tooth formed with an oblique chisel-point, as shown and described.

8. The combination of the circular disk or head having tapering sides, with the cutters or blades secured to the faces of the disk by the countersunk screws and having the briarteeth upon the thicker cutting-edges beveled toward the inner sides and formed with the oblique chisel-points extending in a concentric circular line beyond the periphery of the disk, as shown, and for the purpose specified.

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