CUTTER-HE AD.

Specification of Letters Patent.

Patented July 6, 1909.

App1ication filed October 14, 1908. Serial No. 457,726.

To all whom it may concern:

Be it known that I, OTIs LEE Srsoon, a citizen of the United States, residing at Malden, in the county of Dunklin and State of 5 Missouri, have invented certain new and useful Im rovements in Cutter-Heads, of which the fol owing is a specification, reference being had therein to the accompanying drawmg.

My invention is directed to the production of a cutter head i' or goring veneer blanks, and one of the objects of the invention is to provide a cutter head having cutters arranged to produce V shaped gores.

Another object of the invention is the provision of means for whittling the gores in the barrel blanks.

Still another object contemplated by the invention is to provide detachable knives in order that the same may be readily removed iorlplurposes of sharpening or renewal.

e V shaped gores are formed in the bar rel blanks by a plurality of knives or cutters carried by a rotary head, the said knives tapering longitudinally from their lower base ortion to the outer extremity nearly to a eather ed p e, so that the point of all the cutters of each head will meet in the same plane in a line which determines the angle of the gore being cut and terminates the gore with a sharp angle. The whittling action of the knives may be brought about by utilizing straight knives in conjunction with a swin ing table adapted to move approximate y tangential with the cutter head; b providing a plurality of angularl deflected knives, or a plurality of straight nives inserted in the ead at a slight angle, in the latter two cases the adjustment of the head being commensurate with the deflection of the knives so that each of said knives by virtue of such adjustment will have its maximum whittling action.

With these and other objects in view, the preferred embodiment of my invention resides in that construction and arrangement of parts hereinafter described, illustrated in the accompanying drawings, and embraced within the scope of the appended claims.

In said drawings :F1gure I is a perspective view of a pair of cutter heads mounted in operative relation to a barrel blank. Fig. II is a side elevation of one of the cutter heads. Fig. III is an end elevation of one of the cutter heads, and Fig. IV is a detail view of one of the angular knives.

The head comprises a pair of disks designated by numerals 5 and 6 and detachably secured together by any suitable fastening means, such for example as the screws (7). Referring articularly to Fig. I of the drawings, it wilIbe noted that each of the disks is provided with recesses (8) extending inwardly for a short distance from the periphcry of the disks and radiating from the cen ter, the said recesses being arranged alternately and equidistantly on obverse sides of the head, considered as an entirety, and having a slight continuity of depth in the opposite disk, so that when the knives (9) are introduced into the recesses and secured by the nut and bolt (10) they will be positioned me dially of said head. Each of the knives tapers longitudinally from a point proximate the inner end thereof to its outer distal end and a beveled cutting edge (12). hen the several knives are fastened to the head the cutting edges are disposed alternately to the right and left of said head, and in end elevation, as exhibited in Fig. III, are in staggered relation to one another.

The knives illustrated in Fig. I of the draw ings are straight knives and are mounted concentrically wlth respect to the head, the latter being arranged below the line of movement of the barrel blank (13). In Fig. II, I have shown another method of mounting the knives relatively to the head. In this latter case I utilize straight knives eonjunctively With recesses arranged eccentrically of the head. The same result ma be attained by maintaining the concentrica ly disposed slots and combining knives, the type of which is disclosed by Fig. IV of the drawings, the blade thereof being disposed at a slight angle relatively to the base portion.

In practice, any number of cutter heads are mounted upon a suitable shaft, as 14, in operative adjacency to any type of swing feed, it not being deemed necessai to show said feed as my invention resides a one in the cutter head. While I propose to employ a lurality of cutter heads 1n connection wit a swinging table in order that the required num er of gores may be simultaneously formed in the barrel blank, it is obvious that the single cutter head and an appropriate and is provided with a straight edge (1U feed may be used in lieu thereof for consecutively forming the gores in said blank. As the cutter heads are rotated and the swinging feed table manipulated the blades, owing to their particular arrangement or disposition will e caused to subject the blank to a whittling action, and owing to the longitudinal tapering feature and op ositely arranged cutting edges of the knives the V- sha ed gores are formed, it being of course un erstood that the knives are so accurately adjusted that the extreme point of each knife strikes identically in the same place, and as the blank is forced against the knives the latter cuts from each side of the ore and ar widened until the desired depth and wild is secured, the gores tapering to a fine point toward the center of the bilge of the barrel.

My invention will be appreciated by those skilled in the art owing to the sim l oity of arrangement and construction an the facility and rapidity with which it may be op erated to perform its recited functions.

What is claimed as new is 1. In a device of the character described, the combination of a head having a lurality of longitudinall tapering knives, t e ed es of the adjacent linives converging Qutwar ly toward the center lane of the head.

2. In a device 0? the character described, the combination of a rotary head and longitudinally tapering knives arranged thereon with their cutting edges dis osed lternately to the right and left of said cad, t e edges of the adjacent knives converging outwardly toward the center "lane of the head.

3. In a device 0 the character described, the combination with a head and longitudinally tapering knives arranged alternately on opposite sides thereof, the cutting edges of said knives being dis osed alternately to the right and left of sai head, the ed es of the a jacent knives converging outward ytoward the center lane of the head.

4. In a evice of the character described, the combination of a rotary head comprising a pair of disks, recesses arranged alternately on the outer op .osite faces of said disks, and knives detacha l secured In said recesses media 1y of said disks.

5. n a device of the character described, the combination of a rotary head comprising a pair of disks, recesses arranged alternately on the outer op osite faces of said disks, said recesses extenriin into the 0p osite disks, and knives detac ably secure( in said recesses medially of said disks.

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