GEORGE LE CLAIR, OF MEXICO, NEW YORK, ASSIGNOR OF ONE-HALF TO O. CORTLAND BROWN, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 310.953, dated October 4, 1887.

Application filed May 18, 1887. Serial No. 238,587. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE LE CLAIR, of Mexico, in the county of Oswego, in the State of New York,have invented new and useful Improvements in Tobacco-0utting Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the class of machines which cut leaf-tobacco int-o scraps designed for fillings of cigars; and the invention has special reference to the machine for which I have obtained Letters Patent of the United States, No. 348,402, dated August 31, 1886.

My present invention consists in an improved construction and combination of the essential parts of the machine,whereby the cfficiency thereof is materially increased.

The invention is fully illustrated in the annexed drawings, wherein Figures 1 and 2 are elevations of opposite sides of a machine embodying my improvements. Fig. 3 is an enlarged detail view of the knives employed for longitudinally slitting the tobacco. Fig. 4c is an enlarged detached perspective view of the aforesaid knives and the rollers which co-operate therewith,viewed from the side presented in Fig. 1. Fig. 5 is a top plan view of the machine, portions of the upper sieve andsubjacent I shelf being broken away to show the arrange ment of the lower sieve. Fig. 6 is an enlarged detached perspective view of the rotary cutterhead carrying the transverse cutters. Fig. 7 is a detached plan view of said cutters. Fig. 8 is a vertical longitudinal section of the machine. Fig. 9 is a detached enlarged transverse section of the feed-roller, water-trough, and devices for preventing the gumming of the said roller; and Fig. 10 is an enlarged detached plan view of the crank-shaft which imparts oscillatory motion to the sieves.

Similar letters of reference indicate corresponding parts.

A represents the main supporting-frame of the machine, which is constructed with a longitudinally elongated feed hopper, A. In the said hopper, near the forward end thereof, isan endless feed-belt, D, running on rollers g 9, extended across the hopper. The roller 9 is j ournaled in suitable boxes secured to the sides of the hopper, and has gears m, m, and m attached to its ends, for the purpose hereinafter explained. The other roller, 9, is mounted loosely on a shaft, f, the ends of which project through longitudinal slots f f in the sides of the frame A, and to the protruding ends of said shaft are connected hooks h h, having screw-threaded shanks which pass through the posts of the frame, and are provided with nutsnon theirends. By turning said nuts, so as to cause the hooks to be drawn toward the posts, the roller 9 is drawn in the same direction, and thus the feed-belt D is tightened. Along the discharge portion of the said feed-belt, or in front of and parallel with the roller is a feed-roller, a, journaled in the sides of the frame, and provided at one end with a pinion, j, by which it receives motion, as hereinafter described. The said feedroller is provided with circumferential grooves a a. a, as shown in Figs. 4 and 9 of the drawings, and over this roller and parallel therewith is a mandrel, I), also journaled in the sides of the frame, and has affixed to one and the same end two pinions, K and K, the pinion K meshing in the gear m, and the pinion K, engaging the pinion j, hereinbefore referred to, as best seen in Fig. 2 of the drawings.

On the mandrel b are rigidly mounted a series of circular knives, b, which stand in planes parallel with the line of feed, and are maintained the desired distance apart by means of collars b I), mounted on the mandrel betweenthe knives, as shown in Fig. 3 of the drawings. The knives I) I) run in the grooves a a of the feed-roller a, as illustrated in Figs. 8 and 9 of the drawings. At the front or discharge side of the feedroller a and parallel therewith is a plate, O, extended across the frame and rigidly secured thereto. This plate is provided with fingers c c, which project into the grooves a a of the feed-roller and serve to scrape and clean the said grooves during the rotation of the roller. Over the plate 0 is another roller, (1, parallel with the mandrel b, and journaled in boxes in the sides of the frame A. This roller is likewise provided with circumferential grooves d d, in which the knives b b run, as shown in Figs.

4, 5, and 8'of the drawings. Itreceives rotary motion by means of apinion, 0, secured to one end of its shaft and meshing in the gear m, hereinbefore mentioned. Said roller, rotating in the direction indicated by arrows in the drawings,serves to draw the slitted tobaccoleaves from between the knives 1) band underlying feed-roller a. Under this feed-roller is supported a water-trough, e, in which the lower portion of said'feed-roller runs, so as to immerse said portion thereof in the water and cause the roller when in motion to carry sufficient moisture to the knives b b and to the tobacco in process of being cut to prevent the knives from gumming. Across the dischargeedge of the plate a are arranged to move the transverse cutters O G, which cut the longitudinally-slitted leaves into short and nearly square pieces.

In order to obviate the jarring of the machine incident to the abrupt transverse cuts of the aforesaid cutters, as heretofore con structed, I now form the cutter-head O with longitudinal plates 0 G, which are inclined toward the axis of the cutter-head from the center toward opposite ends thereof, and secure to said plates the cutters O O, which are thus pitched or inclined in the manner aforesaid. The cntting-edges of these cutters I form flaring or divergent from the center toward opposite ends of the cutter-head and at such angles as to reduce the tangential projection of the knives at the center of the cutter-head sufficient to compensate for the increased radial distance of the knives from the axis of the cutter-head at said point, and thus bring the euttingedges equidistant from the axis of the cutter-head and cause them to register with the straight discharge-edge of the plate 0 when the cutter-head is in motion.

By the described form and position of the cutters O O, I produce a shearing out on the tobacco, and thus obviate the jarring of the machine and render the same more durable and efficient. Said shearing out being from the ends of the knives toward the center thereof, tends to crowd the tobacco in the direction aforesaid and insures the cutting of the tobacco.

To the shaft of the cutter-head O are attached the driving-pulley P and pulleys p p. The pulley p is connected by a driving-belt, q, with a pulley, T, which is journaled ona gudgeon rigidly secured to the outside of the frame A, as shown in Fig. 5 of the drawings, and to the shaft of the pulley T is firmly secured a pinion, t, which meshes in the gearwheel m. Across the frame A, back of the feed-belt D, is extended a crank-shaft, 2', having crank-arms t" z" projecting in opposite directions, as shown in Fig. 10 of the drawings. Said crank-shaft receives rotary motion by means of a pulley, T, secured to the end thereof, and. connected by a driving-belt, q, with the pulley p on the shaft of the cutterhead 0.

F represents a longitudinally oscillatory opposite directions.

sieve suspended from the upper part of the sides of the feed-hopper A by hangers a u, and inclined toward the feed-belt D, and terminating over the same to deliver thereto the tobacco leaves placed on said sieve. The sieve F is sufficientl y coarse to allow nails and other foreign hard substances to fall out of the tobacco and through the sieve, and thus obviate the danger of breaking the knives incident to the encounter of the same with said hard sub stances.

H denotes another longitudinally-oscillatory sieve arranged under the sieve F and of the same grade. This lower sieve has a forward extension, H, which is finer and reaches under the feed-belt D and the hereinbefore-described feed-rollers and cutters, as illustrated in Fig.

8 of the drawings. Between the coarse sieves F H is arranged a shelf, I, which is inclined toward the fine sieve H, and terminates over the same. Under the sieve H, at or near its junction with the extension H, are chutes L and L, which diverge so as to convey the screenings from the two sieves H and H in The sieve H, with its extension H, is suspended by long hangers o v at the forward end and by shorter hangers o c at the rear end, and these are inclined with their lower ends toward each other, as shown, thereby crossing said sieve to receive a rearward thrust, which conveys out through the rear end of the sieve, as indicated by the dotted arrow in Fig; 8 of the drawings, such of the substances as are unable to pass through the interstices of the sieve.

In the operation of the machine the cutterhead G receives rotary motion from the driving pulley P, mounted on the shaft of said cutterhead, and from this shaft motion is transmitted to the crank-shaft i by means of the pulleysp and T and their driving-belt q, said crank-shaft imparting reciprocating motion to the sieves, which motion is rendered oscillatory by the hangers u u and o o. The tobaccoleaves, being placed lengthwise on the upper sieve, F, are thereby shaken to eliminate therefrom nails which are occasionally dropped among the tobacco in the process of packing the same in-boxes. The nails and analogous foreign substance drop through the said sieve, while the clean tobacco is moved toward the feed-belt D by the motion of the sieve. The feed-belt, which carries the tobacco to the slitting-knives b 1), receives motion from the shaft of the cutter-head O by means of the pulleys p and T and their driving-belt g, pinion t, and gear m. tobacco longitudinally, receive rotary motion from the pinion m by the pinion K meshing in the pinion m, as hereinbefore described.

The knives b b, which slit the IOC IIO

The subjacent feed-roller a, upon which the tobacco is slitted, receives rotary motion from the arbor of the knives b b by the pinion K on said arbor meshing in the pinion j on the end of the feed-roller, as best seen in Fig. 2 of the drawings. The other roller, d, receives motion from the gear m on the feed-belt-carrying roller 9 by means of the pinion 0 on the shaft of the roller d meshing in the gear on", as shown in Fig. 1 of the drawings. The directions of the aforesaid motions are indicated by arrows in Figs. 1, 2, 4, and 9 of the drawin gs. The cut tobacco falls from the discharge edge of the plate 0 down onto the lower and finer sieve, H, which eliminates from the tobacco the dust accompanying the same and that which is delivered to said sieve by the shelf I. The tobacco cuttings or scraps are shaken to ward and over the sieve H, which allows the said scraps to fall through it, as indicated by arrows in Fig. 8 of the drawings. Such portions of tobacco which may have escaped be-' ing cut to the desired size and are too long to pass through the sieve H are shaken out through the rear end of said sieve, as indicated by the dotted arrow in the aforesaid fig ure.
