COMMlNUTlNG-MACHINE.

SPECIFICATION forming part Of Letters Patent NO. 470,395, dated March 8, 1892. Application filed October 31, 1891. Serial No- 4=10,474-. (N0 model.)

i To all whom it may concern.-

Be it known that I, HENRY A. HANNUM, of Oazenovia, in the county of Madison, in the State of New York, have invented new and useful Improvements in Comminuting-Machines, of which the following, taken in connection with the accompanying drawings,-is a full, clear, and exact description;

This invention relates to a comminuting machine designed, chiefly, for cutting up green bones for chicken-feed, but also adapted for cracking corn, slicing vegetables, and reducing other substances to fine particles; and the invention consists in a novel construction and combination of its component parts, constituting a comminuting-machine of great efficiency and convenience in its operation,

as hereinafter fully described, and specifically set forth in the claims.

In the annexed drawings, Figure l is a side elevation of a machine embodying myinvention. Fig. 2 is a vertical transverse section. Fig. 3 is a top plan view with the yoke and follower removed. Fig. 4C is an enlarged vertical transverse section of the base of the hopper and adjacent parts. Fig. 5 is an enlarged detached side view of the cutter-head, viewed from the smaller side thereof; and Fig. 6 is a view of a section of the larger side of the cutter-head, a portion thereof being broken away to show the attachment of the cutter.

Similar letters of reference indicate corresponding parts.

A represents the supporting-frame of the machine, which frame may be of any suitable shape and formed of metal. It has rigidly attached to it or integral with it an annular raised portion B, which constitutes the bot tom of the hopper B, said bottom being thus convex on its top. Through this bottom is a slot 1), extending radially from one side part way across the same, as clearly seen in Figs. 2 and 3 of the drawings. Beneath the bottom 13 is a horizontal shaft e, disposed at one side of the axis of the hopper and crosswise of the :slot 1) and journaled in suitable bearings I I --'on the frame A. To this shaft is firmly secured the annular cutter-head H, the periphery of which protrudes through' the slot 1).

The peripheral face of this cutter-head is beveled to one side, so that the lower side along one side of the respective slots and se cured in grooves in the cutter-head at the ends of the slots, as shown in Figs. 5 and 6 of the drawings.

In order to obtain ample clearance for the fragments of bones not suffieiently reduced to pass through the slots 12, I widen the slots a a toward the high side of the cutter-head and provide said side of the cutter-head with clearing-notches a a, so that such coarse fragments of bone cannot clog in front of the cutter, but slide along the edge of the slots and through the clearing-notches a and into the hopper, and are again brought around to be acted on by the cutters. The cutter-head may be rotated either by a hand-wheel L or a pulley or gear attached to one end of the shaft 6. Upon the hopper-bottom is mounted revolubly the hopper 13', preferably by providing the former with an annular rib r, inside of which the outer bottom edge of the hopper is fitted, so as to allow the hopper to turn, as best seen in Fig. 4 of the drawings. The hopper is retained in its seat on the bottom B by means of plates P P, secured to posts P P on the frame A and bearing 011 shoulders on the exterior of the hopper above the rack f, which is attached to the base of the hopper B. i i

To the frame A is pivoted a lever g, and to the lever, at opposite sides of the fulcrum thereof, are connected two pawls Z Z, which engage the rack f. A pitman t' connects the said lever to a crank 71, secured to the shaft e, and thus the. lever 9 receives an oscillatory motion, which, by means of the pawls ZZ',imparts an intermittent rotary motion to the hopper B. By throwing one of said pawls off from the rack f, so as to retain it out of engagement therewith, the speed of the revolution of the hopper B can be reduced half when desired, which may be required in comminuting very hard substances.

At opposite sides of the'h'opper B are two standards T T, rigidly secured to the frame A and extending above the top of the hopper. A yoke or cross-bar Y is pivoted at one end to one of the standards and removably connected at the opposite to the other standard, preferably by a notch 'v in the side of the yoke, which notch allows the yoke to be slipped sidewise onto the standard, and a nut 11' on the standard over the yoke prevents the latter from being'forced upward and off from the standard. Central over the hopper B the yoke Y is formed with a half-nut t, and to the side-0f the yoke is hinged a strap 73', formed with a similar half-nut, so that by laying said strap closely against the side of the yoke a complete nut is formed. The strap is retained in said position by a pin 10, passing through perforated ears on the strap and yoke. In the hopper B is a vertically-movable follower 0, to the center of the top of which is firmly attached an upright feed-screw D, which works in the aforesaid nut on the yoke Y. To compel the follower and feed-screw to turn with the hopper, I connect said hopper with the follower by a vertical tongue 3 on one entering a groove in the other.

In operating the described machine the strap 15' is to be swung aside to separate the nut on the yoke, as indicated by dotted lines. in Fig. 3 of the drawings. Then the yoke is to be swung on its pivot to carry it to one side and away from over the top of the hopper. Then the follower O is to be withdrawn from the hopper. The bones or other substance to be cut up or comminuted are then introduced into the hopper, the follower replaced over said substance, the yoke Y swung back over the hopper and secured to the standard, and the strap 25' placed across the screw D and fastened to the yoke. Then by turningthe shaft e the cutter-head II is rotated, and at' the same time-the hopper B, with the follower O and feed-screw D, receiv'es intermittentrotary motion, and by the turning of said screw the follower is caused to press the bones against the cutters c c as rapidly as they are reduced. Inthis comminut-ing operation my machine is rendered very effective by the arrangement of the cutter-head at one side of the center of the convex hopper-bottom and the protrusion of the beveled cutter-head to a point above the apex of the said bottom.

In the operation of the machine the bones are carried successively across the cutterhead from the lower to the higher side thereof, and by the projection of said higher side above the surface of the stationary hopperbottom B a'space is produced directly over at the rear portion of the said bottom, and thus the bones are allowed to be carried freely to the cutter-head from the lower side thereof and the pressure of the follower is directly over the cutter-head.

To clear the cutter-head of the cut substances passing through the slots of the cutter-head, I attach to the under side of the frame A a scraper V, which stands closely to the innerside of the cutter-head, as shown in Fig. 4 of the drawings.

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