TOBACCO-GRANULATING MACHINE.

EEFECIFICATION forming part of Letters Patent No. 318,542, dated May 26, 1885.

Application tiled September 24, 1854.

To @ZZ whom t may concern,.-

Be it known that we, LEANDER BURDICK and NTILLIAM' F. COLEMAN, citizens of the United States, residing at Toledo,in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in TobaccoGranulating Machines; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked hereon, which form a part of this specificaion.

rlhe object of our invention is to provide a simple, durable, and efficient tobacco-granulating machine. v To this end our invention consists, chieiy, in combining with a wire-eloth cylinder a cy lindrical breaker revolved by the friction of the cylinder in the same direction, but more rapidly, said breaker being composed of a number of independently-rotating blocks,

each provided with a number of cups or pockets in their periphery, whereby the tobacco is both carried over and broken, or caused to pass and repass under the breaker, each of said blocks also being provided with a cen tral hub for keeping` their faces apart and al lowing independent movement.

Our invention further consists of a novel combination of parts, all of which will be described below, and pointed out in the claims.

In the drawings, Figure 1 is a front View. Fig. Qis a rear View. Fig. 3 is a side elevation, partlyin section. Fig. tis a detail view of one of the breaker-blocks. Fig. 5 is a detail view of a portion of the breaker removed from the cylinder.

Like letters refer to like parts.

A A represent the frame supporting the machine. To a side extension of said frame a double journal, B, is bolted. Through this journal extends a short shaft, O, carrying pulleys a, b, and c, and a conical cog-wheel, d, the latter turning the cogged rim, E, which is a part of the cylinder-head, as will be described below. The pulley a is a loose one for shifting the belt. Motion given to the pul- (No model.)

ley b by any suitable prime motor will therefore cause the cylinder D to revolve.

As regards the cylinder, the head of it is composed of the hoop or flange D, the coggcd rim E, and the short open drum F, all cast in one piece. (See Figs. l and 3.) The open drum permits the tobacco to be conveniently inserted into the cylinder, and the rim E acts to turn it in connection with the cog-wheel d, above mentioned. Upon the circumference of the drum is a raised portion, having a groove, k, in which two opposite pulleys or sheaves, L L, revolve by the friction ofthe parts. These pulleys are journaled in raised standards c e, bolted to the frame. The drum and pulleys therefore both support the front of the cylinder and hold it in place during its revolution. The main portion of cylinder D is composed of wire-cloth D2, which should be of a suitable mesh for allowing the granulated tobacco to pass through after being sufficiently acted upon by the breaker, hereinafter described. The wire cylinder is held in position by three inside band-iron ribs, M M, and at the ends of the cylinder the ribs and the wirecloth are held together by external wooden strips, N N, extending the whole length of the cylinder, all of said parts being` united by a nutand-bolt fastening, f f, and the ends of the cylinder being further fastened by a series of short bolts, j, held by nuts. The rear end of the cylinder (see Fig. 2) consists of an open spider, G, composed of the circular iiange or rim G', the radial arms H, and the hub I. The special purpose of this open construction is to allow the refuse to escape during the granulating process, at the same time giving ample strength to the rear end of the Cylinder. The hub extends rearward in the form of a reduced shaft, l,which revolves in a metallic box, 1",supported between the u prights fi ,crosspiece i', and a screw,l,between the said uprights. An endview of the box seen in Fig. 2 and a section longitudinally in Fig. 3. The main portion of it is square,with a central opening which forms a journal for the shaft 1. The inner end of it has a raised square flange, as, which acts as a washer for thc spider-hub, and serves as an additional support and guide for the reduced portion of the box,which has free vertical play between the uprights. The lower side of the box rests on the screw I3, the purpose of thelatter being to raise and lower the boX, and hence through the shaft andspider to give any desired in eline to the cylinder when in operation.

The construction and arrangement of the breaker Owill now be described. It is composed of a series of circular wooden blocks, o o, strung on atube, o', the breaker as a whole being nearly as long as the cylinder. NVithin the tube is a tie-rod or shaft, o2. The special construction of the individual blocks is seen in Fig. 4. In practice they have a diameter of about eight inches. In the periphery are the cups o3, the backs of which ter ininate in a saw-tooth, the fronts being bevcled. The purpose of't-hese cups is tocarry the tobacco over and over, or to cause it to pass and repass constantly under the break ers. The central opening, o4, has a diameter of about three inches, and about thisis a hub or raised iiange, o5. This integral hub holds the faces of the breakers apart, and, as the breakers are not joined, permits each one to revolve independentlyr of the other. The tube o should be of less diameter than the openin g 0*, and the diameter of the rod o2 less than that of the tube, so as to give the parts ample freedom of movement.

The location of the breaker in the cylinder is seen in Figs. 2 and 3. Itis revolved by the friction of the latter in thevsame direction and at a more rapid rate. Each block may not move at the same speed, as they are disconnected, and the tobacco may afford varying resistance.

The breaker is held in ,the cylinder as follows: At the front end of the tie-rod otis an arm, a, which is fastened-to a cross-tie, at, extending through the drum F and engaging by a setscrew, x, with a depending curved arm, a, bolted to the frame. The other end ot' the tie-rod engages with anv arm, a, fastened to the cross -tie a5, which passes through the hub and shaft Il. The crosstie ci is ot' less diameter than thel opening lh rough these, so that the breaker can be rolled in the cylinder to varying positions. These cross-ties fr ai are round, with squared ends where they pass through their respective arms. The said cross-tie a5 is fastenednear its outer end by a set-screw, x2, to a depending arm, a". rlhe lower portion of the latter is attached by a bolt and nut to atransverse block, al. This block is not fastened. rIhe outer face of itextends slightly over the uprights, but the rear portion is reduced to fit snugly between them, preventing lateral motion, but leaving the block free to move vertically or to be removed wit-h the arm a. It will be seen that the inclination of the breaker changes with that of the cylinder. In order to change the locationA of the former, the cylinder being at rest, loosen the set-screws and remove or loosen the arms rlhe breaker will then drop to the bottom of the cylinder. Then put a block or rest behind the breaker to hold it against the cylinder, and turn the latter by hand until the breaker is raised to the desired position. The arms, being changed as to inclination as the case may require, may be fastened again, also the setscrews, and the breaker willbe securely held. On account of the bolt-fastening of said arms they can be changed one-eighth or one-fourth, and meet all requirements. The block al, having n0 lateral play,will maintain the angle of arm aG. It has been found by eX- perience that the location ot' the breaker as shown in the drawings is the right one for practical working, and if placed there in the 1i rst place there will never. or rarely, be any change required. VVben the tobacco is granulated, it passes through the meshes of the wire cylinder,and is received by a series of vibrating wire sievesbelow. (See Figs. 1 and 3.) These are designated as l, 2,v and 3. They are held in a frame, l?, by means of cleats p p. The frame is suspended by steel straps P', which cross each other and are fastened to the front of the cylinder framer by screws and cross-straps, and are also joined to the front of the sieve-frame by being passed aroundrollers x3 in the metal brackets p. The rear end of the sieve-frame has short supporting-straps P2; but they do :not extend below the top, of said frame, in order not to interfere with the sliding sieves or any suitable device which maybe used to remove thetobaccofrom them. The sieve-frame is vibrated by an eccentric, R,on a shaft, r, by means of a connecting-rod, E, attached to the eccentric and the bottom of said frame, the shaft r being revolved bythe pulleys c c and a belt. The first sieve is sufficiently coarse to allow the properly-granulated tobacco to pass to the second, but carrying that too coarse into any suitable receptacleat the end of the machine, to be run through again. The second sieve, being of finer mesh, allows the dust and tine tobacco to pass to the third,which is of still iner mesh. l The latter sifts this flue dust into drawers S S beneath. The granulated goods may be removed from the second sieve by any desirable means.

In making our peculiar form of breaker we do not limit ourselves to wooden blocks, as any suitable material will answer. In practice our machine is covered by an outside case with an oval top, presenting a neat box-like appearance; but we do not deem this important to show.

Having fully described our invention, what we claim, and desire to secure by Letters Patent, isl l. In a tobacco granulator, the tobacco breaker composed of a number of l adjacent circular and. independently moving blocks with pockets arranged at intervals in their peripheries, and each -having a central hub, combined with a shaftupon which they are supported, a wire-cloth cylinder, and means for rotating said cylinder, as set forth.
