TOBACCO-CUTTING MACHINE.

5PECIPICATION forming part of Letters Patent No. 327,885, dated October 6, 1885.

Application filed April 15, 1885. Serial No. 162,373.

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 TobaccoCutting Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to machines employed for cutting up tobaccoleaves into scraps to be used for the fillings of cigars.

My invention consists in an improved combinatiomwith the feed-bed, of two sets of cutting-blades secured stationary on the end of said bed, and arranged alternately with one set projecting beyond the other set, a rotary cutter-head arranged with its axis parallel to the plane of the stationary cutting-blades,and cutters projecting different distances from the head to pass between the projecting stationary blades,and across the front of the same, all as hereinafter more fully described,and specific ally set forth in the claims.

For the operation of prior machines'of this class the tobacco had to be first dried before passing through the machine. The result was that the tobacco became more or less broken into small particles, causing considerable dust and waste, and requiring the employment of a sieve for separating the dust from the scraps. Furthermore, it entailed the extra labor of moistening the scraps preparatory to working them into cigar-fillings. All of these defects are obviated by my improved machine. By means of this machine I am enabled to cut the scraps immediately after the tobacco leaves the strippers, and while yet moist, and thus produce scraps in proper condition to be worked into cigars, thereby effecting a great saving of time and labor, and also dispensing with the sieve, and preventing dust and waste of tobacco.

In the annexed drawings, Figures I and II represent elevations of opposite sides of my improved scrap-cutting machine. Fig. III is a vertical longitudinal section thereof. Fig. IV is a top plan view of the same. Figs. V and VI are respectively a detached plan view and a longitudinal section of the station- (No model.)

ary cutter on an enlarged scale. Figs. VII and VIII are detached plan views of the knives, which are mounted on the rotary cutter-head; and Fig. IX is a transverse section of the latter.

Similar letters of reference indicate corre' sponding parts.

F represents the frame of the machine, formed either of wood or metal, and of any suitable shape to properly support the mechanism hereinafter described. On top of said frame is secured a feed bed or trough, T, at the discharge end of which is the stationary cutter or knife A, arranged with its top surface flush with that of the feed-bed. Said cutter A is composed of two sets of parallelsided blades,a a and a a, arranged side by side, and adj ustably attached to their carrier C, which consists of a stout metal bar firmly secured across the frame F, as shown in Fig. VI of the drawings. The two sets of blades are arranged alternately, and in such a manner that the cutting-edges of one set project beyond those of the other set, as illustrated in Fig. V of the drawings,said cutting-edges projecting from the discharge end of the feed-bed.

The attachment of the blades is made by screws passing through slots in the blades and entering the bar C, thus allowing the blades to be detached when required for sharpening or renewing, and also to be set out the requisite distance to co-operate with the rotary knife, hereinafter described. By means of set-screws e e, passing through a shoulder, s, on the bar C, at the back or heel of the blades, and bearing against the latter, said blades are sustained endwise in their position.

In front of the stationary cutter A is a retary cutter-head, B, arranged with its axis parallel to the plane of the stationary cuttingblades or a. 011 opposite sides of said cutter head are distributed in a row extending the length of the cutter-head, and are secured,thc blades b and c. The blades 1) are arranged to project from the cutter-head at regular intervals, and to the same extent as the projection of the blades a beyond the blades to of the stationary knife, the projecting blades 6 b being in range with the spaces between the projecting blades a a, and in the rotation of the cutter-head pass through the said spaces. The blades 12 b are attached to the cutter-head by a cap, d, detachably connected with the cutterhead by screws 73 72, passing through the cap and into the cutter-head, by means of which screws said cap is clamped onto the blades. The cutter-head is provided with a shoulder, s, at the heel of the blades, and through said shoulder pass adj ustingscrews e e", by means of which the blades can be set out when required,to compensate for wear of their cuttingedges.

The blade 0, which is attached to the opposite side of the cutter-head, has a straight and uniform cutting-edge, and is set so as to pass closely across the projecting cutting-edges of the stationary knife A, as illustrated by dotted lines in Fig. VIII of the drawings. The blade 0 is also adjustably secured in its position by a cap, d, clamped on the cutter-head, and by set-screws e e at the heel of the blade, in a manner similar to the attachment of the blades 1) b.

The tobacco is fed to the cutters intermittingly and automatically with the continuous rotary motion of the pivoted cutter-head by the following instrumentalities:

On one side of the frarneFis pivoted agearwheel, k, provided with a handle, Z, by which to turn it. This wheel meshes inapinion, m, affixed to the shaft of the cutter-head B, which thus receives its rotary motion.

To the opposite end of the shaft of the cutter-head is attached a balance-wheel, W, to overcome the intermittent checks of the mo tion incident to the intermittent action of the cutters.

Immediately back of the balance-wheel is an eccentric, n, attached to the shaft of the cutter-head, and with said eccentric is connected an eccentric -rod, 0, the free end of which slides in guides p ;,attached to the side of the frame F, as shown in Fig. I of the drawings.

Beneath the feed-bed T, and at right angles thereto, is journaled a feed-roller, R, the up per portion of which projects slightly above the feed-bed, as shownin Fig. III of the drawings, and on the journal of this roller is fastened a ratchet-wheel, r, with which engages a pawl, t, connected with the eccentric-rod 0.

Over the roller R is another roller, L, which is rotated synchronously and at the same speed with the roller R by pinions u and u, connected, respectively, to the journals of the two rollers, as represented in Fig. I of the drawlngs.

Another roller, L, is in front of and parallel with the roller L, and around the said two rollers is extended an endless apron, N, which is made to travel with its lower portion toward the cutters. The journals of said rollers L and L are mounted in bearings which are yieldingly supported, so as to allow the rollers a limited vertical play, and in a degree accommodate themselves to the thickness of the tobacco passing beneath them.

Various devices have been resorted to for feeding moist tobacco to the cutters; but none have been able to obtain the requisite hold on the tobacco to accomplish the desired object. After thorough tests I have found that a traveling endless apron composed of textile fabric is capable of performing most successfully the function of conveying the moist tobacco to the cutters.

In operating my machine the tobacco is placed on the feed bed or trough T and passed between the apron N and lower feed-roller, R, motion being in the meantime imparted to the rotary cutter-head H by turning the crank or handle Z. The feed-roller R and apron N receive intermittent motion by means of the eccentric a, eccentric-rod 0, pawl t, ratchet r, and pinions u u. Each impulse of the feedroller It and apron N moves the tobacco a distance equal to the length of the projection of the cutter-blades a, and during the intervals of rest of said roller and apron the rotary cutter-head B carries the cutters b and c alternately into action with the stationary cutter A. The blades 6, passing between the blades a a, cut out of the tobacco square scraps, leaving similar square uncut portions between the cuts. The next impulse of the feed-roller and apron moves the tobacco a distance equal to the depth of the cut, and whilein this position the straight blade 0 is caused to cut ofi the projecting square portions of the tobacco,and the blades 12 12 make other incisions in the tobacco lying upon the stationary cutter, thus producing with great rapidity scraps of uniform size and shape.

It will be observed that by the described construction of the cutters each set of said cutters performs half of the work required of the machine, and the clogging of the cutters is effectually prevented.

A spout, V, carries off the scraps from under the cutters.

The described machine can be adjusted to out the scraps into shape suitable for smokingtobacco by setting the blades on and b so as to project less from their carrier or head.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, 1s

1. In combination with the feed-bed T, two sets of cutting-blades, a a, secured stationary on the end of said bed, and arranged alternately, with one set projecting beyond the other set, the rotary cutter-head B, arranged with its axis parallel to the plane of the stationary cutting-blades, and cutters projecting different distances from the head'B, to pass between the projecting stationary blades and across the front of the same, substantially as set forth.

2. In combination with the feed-bed T, two sets of cutting-blades, a a, secured stationary on the end of said bed, and arranged alternately, and with one set projecting beyond the other set, the rotary cutter-head B, arranged with its axis parallel to the plane of the stationary cutting-blades, a series of cutters, b b, distributed over the length of and secured to the rotary cutter-head, and projecting into the spaces between the projecting stationary cutting-blades, and the cutter a, secured lengthwise on the rotary cutter-head, and having a continuous cutting-edge, substantially as specified and shown.

3. The combination of the stationary cutter A, composed of two sets of blades, a a and a a, secured adjustably endwise to their carrier, and arranged alternately, and one set projecting with its cutting-edges beyond those of'the other set, the cutterhead B, pivoted in front of the stationary cutter A, the blades 12 6, se-

cured adjustably endwise to one side of the aforesaid cutterhead, and arranged in range with the spaces between the projecting blades of the stationary cutter, and the blade 0, having a continuous cutting-edge, and secured adjustably to the opposite side of the rotary cutter-head B, all constructed and combined substantially in the manner specified and shown.

In testimony whereof I have hereunto signed my name and aflixed my seal, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 25th day of March, 1885.
