AUBREY M. WHITNEY, OF PROVIDENCE, RHODE ISLAND.

ROTARY TOBACCO-CUTTER.

SPECIFICATION forming part of Letters Patent No. 417,962, dated December 24, 1889.

Application filed November 8,1886. fierial No. 218,226. (No model.)

To all whom it may concern.-

Be it known that I, AUBREY M. WHITNEY, of the city and county of Providence, and State of Rhode Island, have inventedcertain new and useful Improvements in Rotary Tobacco-Outters, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to amachine for cutting or slicing tobacco into thin pieces, and is equally applicable for cutting other materials, such as vegetables.

The objects of my invention are to provide a cutter that is a self-feeder and can be easily manipulated by one hand of the operator, and that is very efficient in work and compact in form.

To the above purposes my invention consists, principally, in the automatic feeding mechanism and the peculiar construction of the catch funnel and the connected discharge-chute, and of the support-stand for the superstructure, and in other novel constructionsand arrangements of the parts of the device, all as hereinafter fully described and claimed.

In the accompanying drawings, illustrating my invention, Figure ;1 represents a side elevation of my improved cutter, thesupportstand of which is in central vertical section. Fig. 2 represents a front elevation of my device, with the feeding mechanism and the superstructure of the support-stand shown in central vertical section and the catch-funnel as broken away. Fig. 3 represents a top plan view of Fig. 1, with the cover omitted and the feed-bar in cross-section. Fig. 4 represents an enlarged detail top plan view of a portion of the cover with the feeding mechanism. Fig. 5 represents an enlarged detail sectional view of a portion of the catch-funnel, the cutter-disk, and the cover.

In the said drawings like numbers of reference designate corresponding parts throughout.

Referring to the drawings, the supportstand 7 is a hollow column having a flaring resting-base, and is formed with a circular top opening, around which is the flange or collar 8. The side of the stand 7 is provided with a large opening 9, through whichaccess is had to the interior thereof.

The catch-funnel 10 is a hollow truncated cone-shaped body inverted, and is provided at the small end or base thereof with an eccentrically-disposed discharge-chute 11, which is of an ordinary scoop shape and has its inner surface continuous with that of the catch-funnel, the base of thefunnel from where the chute arises being of a perfect circular form. Upon the outside of the catch-funnel is a projec-' tion or arm 12. Across the interior of the funnel is disposed a cross-piece 13, provided with a journal-bearing 14. The catch-funnel is slightly flattened at 15 near the top and is cut away on the edge of the flat portion. At two opposite points on the exterior of the funnel are formed the forked lugs 20, which are designed for the purpose hereinafter described. This catch-funnel 10, together with the discharge-chute 11, the interior cross-piece 13, and the exterior arm 12 and lugs 20, are all cast in asingle piece. This is an important and useful feature in this class of devices, since it serves to strengthen and condense the structure and to render less expensive the construction. The catch-funnel is set with the base thereof resting snugly within the collar 8, where it is held securely against movement by the screws 16, which may bind upon the exterior of the catch-funnel or may pass through the body thereof. In this position the discharge chute projects downwardly through the opening 9 in a convenient position. Upon the back of the discharge-chute 11 is arranged a spring catch or finger 46, designed to receive and hold securely the edge of a bag, as 44, when placed over the chute,

as hereinafter described.

The rotary cutter-disk 17 is a fiat plate provided with four equidistant radial slots 41, in which are set the blades 18, which leave the outer ends of said slots open for the tobacco to fall through, as herein after described. This cutter-disk is cast with the radial peripheral cogs or gear 19, and is forrncdwith the annular depression or groove 43 in the cutting-face thereof near the edge. Upon the under face of the disk is the central integral journal or shaft 23, which is journaled in the journal-bearing 14 of the cross-piece 13. The

- lugs in an evident manner.

blades 18 all have their cutting-edges disposed in the same direction and to the upper face of the disk. At the center of the cuttingface of the disk 17 is formed the screw-threaded socket 21.

22 is a shaft formed with a worm or screw thread running throughout the greater part thereof and is set into the socket 2,1 of the cutter-disk by means of a screw-thread and stands fixed at right angles to the disk and is rotated by the motion of said disk. The upper free end of the shaft 22 is enlarged and of a cylindrical form.

The cover 24 is fiat and is provided with a depending annular tongue 42 near the edge and with a marginal flange, and is shaped suitably to rest upon the upper edge of the catch-funnel 10 and to house the cutting-face of the cutter-disk 17. The coveris provided with two hinged latches 28, which are disposed at diametrically-opposite points on the edge thereof'and are designed to swing down and lock in the forked lugs 20, as clearly indicated in Fig. 1. These latches and lugs serve to hold the cover 24 securely in position, and the cover may be released for removal by merely swinging the latches outwardly and upwardly to clear the forks of the coacting WVhen the cover is mounted in position, the tongue 42 thereof is nested snugly in the groove 43 of the disk, so that while the disk revolves the particles of tobacco are thrown by the centrifugal force from the face of the disk against the tongue 42, from where they will fall through the slots 41 into the catch-funnel.

To one side of the center of the cover 24 is constructed the rectangular feed-box 25, which is formed integral with the said cover and stands normal thereto. The feed-box 25 is open at the top,and the bottom thereof opens and feeds directly onto the cutting-face of the cutter-disk 17- and within the field of the passing bladeslS. In the side of the feed-box, opposite the center of the cover 24, is formed the vertical open way 26, which is open at the top. The rigid arm 27 is fixed firmly to the side of the feed-box 25, and at the upper free end of said arm is formed a journal box or bearing, in which the upper end of the feed-bar 22 is journaled, as shown, in order to prevent the feed-bar from Wabbling when revolved. The feed-bar is readily removable from its mounting by unscrewing it from the socket 21 of the cutter-disk 17 and then passing it upward through the bearing in the arm 27.

The presser 29 is provided atone end with a fiat plate 30, and at the other end is formed with a socket-eye 3], which is sufficiently large to allow the feed-bar to pass loosely dle portion 35 of the arm will lie in mesh with the worm or. screw-threads of the feedbar 22, with which the saddle-arm is pressed into constant engagement through the office of the spring 36, which is mounted upon the presser-plate 30. The presser-plate 3O lies within the area of the feed-box, and the presser extends through the open way 26 of said box, so that the presser is adapted to travel up and down within the feed-box in accordance with the direction in which the feed-bar is turned. The working of the presser in the open way 26 prevents the same from having a lateral or rotary motion, and causes the presser to maintain arectilinear motion in its operations.

Thepresser 29, together with the saddlearm 33, works up and down on the threads of the feed-bar like a nut, and the bar is easily removed therefrom by withdrawing the sad dle-arm from out the slot 32 against the force of the spring, so as to disengage the arm from the feed-bar, which may then be slid through the socket-eye 31.

By virtue of the constructionof the feed screw bar 22, thepresser29, and the feed-box 25,

and the actuating cutter-disk 17, the feeding mechanism is automatic in action, since the rotation of the cutter-disk the one way or the other will serve to feed the presser up or down, respectively, within the feed-box.

The cutter-disk 17 is rotated or driven by means of the hand-wheel 37, which is cast with the annular crown cog-gear 38, concentric therewith. The hand-wheel is journaled by means of a central eye upon the fixed journal or shaft 39, which is forced in a boredout socket in the arm 12 and held therein by a set-screw. The hand-wheel is held on its journal 39 by the linchpin 40, and is turned by the operator manipulating the attached handle. The crown cog-gear 38 is placed in mesh with the peripheral cogs 19 of the cut-- ter-disk 17. at the cut-away edge 011 the flattenedside1'15 of the catch-funnel, and the.

The material or plug-tobacco that is to be out or chopped is placed within the feed-box by first raising the presser clear of the feedboX, as in Figs. 1 and 2, and swinging it to one side, so as to give access to the interior of said box. The presser is then adjusted in position, so as to travel within the box, and the saddle-arm 33 is placed in mesh with the feed-bar. The hand-wheel is then turned in a direction to drive the blades with their cutting-edges first, and this serves to turn the feed-bar in a direction suitable to feed the presser gradually downward, whereby the plug-tobacco is gradually fed with a slight pressure to the cutting-face of the cutter-disk. The chips of cut tobacco fall into the catchfunnel, which leads them into the dischargechute, from where they may be caught in a hand-wheel, in which case the feed willbe in the rotation of the cutter-disk.

suitable receptacle in a finished state. The end of the discharge-chute is at a convenient location and is of a handy shape to spring the mouth of a bag,- as 44:, (represented iii broken lines in Fig. 1,) over it to catch the cut tobacco as it is delivered' Then the bag 44: is placed in the position shown in Fig. 1, with the edge of the mouth caught under the spring-catch 46 and with the bottom thereof resting upon the curved resting-surface 45 of the support-stand, the bag will remain in place without being held, as the cut tobacco falls into it and fills the bag, which may then be removed. This convenient manner of placing and filling the bag is important, since it does not need the attention of the operator while being filled.

I construct the rotary cutter-disk 17 withv the peripheral radial cogs 19,in preference to a bevel cog-gear, in order to obviate the evil of the particles of tobacco which necessarily become lodged in the teeth from interfering with the adjustment of the feed, since in the case of the bevel-gear the lumps of tobacco lodging in the cogs tend to press the cutterdisk upwardly, and so to increase the pressure of the tobacco upon the disk, thereby interferin g with the proper feeding of the same. In the use of the radial cogs on the cutterdisk the presence of lumps of tobacco formed in the cogs will cause the disk to be pressed to one side of the intermeshing gear 38 of the no wise disturbed. Again, to further obviate the bad effect of the tobacco lodging in the cogs of the gears, I have provided a very efficient excluding means in the tongue 42 of the cover and the groove 43 of the disk, whereby the particles of loose tobacco which fall upon the cutting-face of the disk and would otherwise find their way to the cogs of the gears are thereby caught and fall down into the catch-funnellO, as before described. The pitch of the worm or the screw-threads of the feed-bar 22 may be varied in order to regulate the pressure with which the tobacco is fed to the cutter-disk. In any case the pressure should not be sufficient to impede The greater the number of blades used the greater will accordingly have to be the pitch of the screwthreads, so that the feed may be fast enough to supply the blades. By virtue of the automatic feed and the consequent pressure therein exerted I am enabled to work the cutter with unusually high speed, and the actual use of the device shows that the four cutterblades may be used with the greatest advantages- I My improved, form of cutter provides a durable machine that is neat and portable, and one that may be rapidly and efficiently worked by one hand of the operator. Obviously the device may be employed to out other material than tobacco, and will prove equally efficient.

There may be various modifications made in the parts of my device without, however, making a substantial departure from the spirit of the invention as herein described and claimed.

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