It the accomplishment of this ob ect and such others as may hereinafter appear, the

invention consists of the arts and combina-. hilly described, and partic arly pointed out in the appended claims, reference being had to the accompanying drawings, forming a part of this specification, in which the same reference characeral views.

Referrin to the drawings by reference characters, A esignates the main frame upon which is erected a pair of uprights B, in which is journaled (in boxes b) the main shaft 0, which latter carries atone end a large sprocket-wheel D and a feed-drum E. The feed-drum is provided in its periphery with transverse grooves e of any suitable configuration in cross-section, these ooves lying close together and parallel wit each other. A circumferential oove or slit e is formed in the eriphery o the drum, so'as to intersect a the grooves e. A sprocket-chain F connects the large wheel D with a smaller s rocket-wheel G, carried on the end of a s aft 11, which shaft is journaled in boxes hand in turn carriesa large sprocket-wheel I. This sprocket-wheel I is connected by a chain J to a smaller sprocket K, carried by a trans journaled in boxes land carryingon one o its projecting Specification of Letters Patent. 7 Application as a 23.1905. sci-1.1x. 276.892.

ends a lar .e band-wheel M andtwo smaller band-whee N N, one of which lattbris loose on the shaft. The band-wheel M is connected by a belt 0 to a pull'e P, secured on the end of the saw-arbor P, t arbor being journaled inboxes p, bolted adjustably to wings or flanges b, vertically slotted for the purpose of adjustment, these wings bein carried by the standards B. Attached to th% arbor P is a SBIlGSx of circular-saw cutters, which areso spaced on the arbor that the central one works in the groove 6 and the other to overlap and Work close to the respec- "tive' side edges of the feed-drum; The cutters may be adjustably mounted on the arbor in order thatthey maybe set to suit drums of various widths when it is desired to vary the length of the rods to be cut.

The 'front'upper edges of the standards B are notched at b for the rece tion of the respective ends of a cross-bar thiscross-bar being provided with vertical slots t to enable it to be vertically adjusted and also with-a longitudinal horizontal slot t. Bolted to the front face of the cross-bar T by means of a 'bolt'working in the slot;t is an angle-iron U whose lower end inclines forwardly and downwardly. 7 lies against the front face of the bar T is vertically slotted, this slot crossing the slot t, and passing through these intersecting slots is an adjustable clamping-bolt. The end of the part U is longitudinally slotted to. coin- The part of this bar Unwhich' cide with a longitudinal 'slot v in another angle-iron V, whose. forward portion inclines upwardly and forwardly and has attached to it a pair of cross-bars '0, these cross-barsin turn carrying a pair of parallel bars 4;. These bars 'v incline upwardly and forwardly in parallelism with thebars T, which constitute the feed-table and which are bolted adjustabl to a frame R, this frame being provided wit a slot 1" to permit the bars 1 to be adjusted to andfr'om-each other to acc6mmo date rods of various widths. The lower ends of these bars 1' are attached to bracketsm', which are adjustably bolted to a frame R, which is prov1ded with a slot 1' similar to the slot 1', so that the inner ends of the feed-table bars may be adjusted to correspond with the outer ends. r

It'will be observed that when ower is applied to shaft L the belting an chains will impartra very slow movement to the drum,

and a comparatively rapid movement to the rotary cutters. The rods to be cut into lengths are fed down the table, the bars 12 serving to guide them singly to the feed drum, and as the drum rotates the rods drop into the grooves therein and are carried backward under the rotating cutters, by which they are accurately and nicely severed into lengths. As the drum continues to rotate the severed rods drop-onto the delivery-table 20, which delivers them onto the floor or into a suitable rece tacle. It will be observed that the tableare r and the guide-bars o serve as a sort of magazine for the rods to be cut and that the inclination of the table-bars and the magazine is sufficient to cause an automatic feeding of the rods, so that it is simply necessary to keep a sufficient quantity'of the rods on the table to fill the magazine. It will be observed that the adjustment afforded by the slot u enables the guard-bars v to be bodily adjusted to and from the drum and that the extensibilit of the overlapped supporting-bars U and enables the guard-bars to be bodily adjusted toward and from the table-bars, whereby the feed-channel may be accurately adjusted to suit rods of varying thicknesses.

It will be apparent to those skilled in the art that various mechanical embodiments of the invention are possible, and I therefore do not wish to be limited to the exact arrangement and construction shown.

What I claim, and desire to secure by Letters Patent, is

1. In combination with a frame, a rotating drum provided with transverse grooves in its periphery, a shaft carrying cutters working alongside of the respective ends of said drum, means for delivering the articles to be cut to the rooves in said drum, means for rotating the drum and the cutters, and means for feeding the articles into the grooves of the drum, this means consisting of a table inclining downwardly toward the face of the drum, a

combination of a grooved drum, rotary cutters, means for simultaneously rotating the drum and the cutters, and means for feeding the articles, consisting of a table inclining downwardly toward the drum, guard-bars and supporting devices therefor, these guardbars lying above and parallel to the table and terminating near the periphery of the drum and the supporting devices for these guardbars being vertically adjustable and extensible, whereby the guard-bars may be bodily adjusted toward the drum and also toward the table, substantially as set forth.

In testimony whereof I hereunto afliX my signature, in the presence of two witnesses, this 19th day of August, 1905.
