To a/Z whom, it may concern.'

Be it known that I, CHARLES F. SMITH, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Meat-Cutters, of which the following is a specification.

My invention relates to improvements in meat-cutters; and the objects of my invention are simplicity and economy in construction andefficiency in use.

In the accompanying drawings, Figure l is a central vertical section of themain portions of my meat-cutter with some of the parts in elevation, the plane of section being indicated by the line Je :0, Fig. 2. Fig. 2 is an end View of the case and forcer, the knives and clamping-ring being removed. Fig. 3 is a plan view of the knives or cutters that belong on the delivery end of the forcer, together with a portion of the forcer. Fig. L is a side View of the compound knife, showing the outer side, which works against the perforated plate. Fig. 5 is a like View of the reverse side of the said compound knife. Fig. 5%,- is a sectional view of the same on the line y y of Fig. 5. Fig. 6 is a side view of the perforated plate. Fig. 7 is an end view showing the delivery end of the forcer in a modified form. Fig. 8 is a side view of the knives for said modification, showing the outer side. Fig. 9 is a plan View of the same. Fig. l0 is a side viewishowing the outer side of the inner one of the said knives.

The forcer A is mainly of an ordinary form, the crank end having a journal or shaft portion 8, the outer end of which, that receives the crank, being represented as broken off. The delivery end of the forcer has a short shaft or journal 9 and a driving portionlO of an angular form. The body of the forcer has the ordinary screw form, composed of the main thread 1l and two additional threads ribs, and I prefer to employ spiral ribs 15 for the main portion of the case, with short terminal rib portions 16 arranged to extend longitudinally of the case at the delivery end. The case is mainly of a cylindrical form, but flares outwardly on an abrupt taper 17 at the delivery end,the space between the feeding-ribs throughout the whole length of the case conforming substantially to the exterior form of the case, while the tops of all the ribs in the case Afollow the cylindrical form of the forcer from end to end of the interior bore of the case so far as the ribs extend. This makes the terminal portions 16 of the ribs very deep or high at their outer ends, as shown, a little more than three times the depth of the spiral ribs 15 in the main body of the case. The ends of these terminal portions are faced off, preferably at right angles to the axis of the case, to form cutting-faces for acting in connection with the knife hereinafter described. -Adjacent to the end portions 16 of the ribs there is a short cylindrical chamber 18 for the knives to rotate in, and outside of that a larger cylindrical portion 19 to receive the stationary cutter 20, which, as shown, is in the form of a perforated plate. The case is provided with a fixed pin 2l and the edge of the perforated plate with a notch or recess 22 to receive the said pin or with other ordinary means to prevent the perforated plate from rotating. The case at the delivery end is provided-ovali an external screwthread 23 to receive the nternallyfthreaded clam ping-ring M -,that holds the perforated plate in place and presses the plate against the knife acting in connection therewith.

In the preferred form I make an integral compound knife-that is to say, what prac` tically constitutes two different knives or two sets of knife-edges made in one and the same piece on a common body portion. On that side of the hub 25 that faces the forcer there is an angular driving-socket 26, that fits on the driving portion lOQof the forcer, and leading from the said socket to the opposite side of the hub there isa round hole that substantially ts the journal 9 on the end of the forcer, so that this compound knife cannot IOC whereby the outer knife or knife-edges 27 K in number, extend from the extreme outer ends of the knifeblades tothe hub 25, into which they merge. J ust in front of the inner ends of these edges the hub is recessed or cut away, as at 29, to a depth which brings the bottom of the recess at a point a little inside the inner faces of the feeding-ribs and inside the tops of the threads of the screw-forcer to permit the meat to flow more readily than it would if all of the meat were forced outwardly beyond the periphery of the forcer. Although the hub is recessed, as at 29, it is large enough as to its major portion Ato extend outwardly and bear for a short distance on the end faces of the cutting-ribs 16, or, in other words, said hubis in the main a little larger than the bore of the case at the inner side of the feeding-ribs. Theknife or knife-edges 27 are set back from the edges 28,face the perforated plate,'against which theycut,and extend inwardly much farther-than the said edges 28 and preferably to the central hole orjournal-bearingr on that side of the hub, the said edges 27 projecting for- Wardly from the knife-arms on the broad side of the hub, so that' a clear space or chamber is formed between the cutting ends of the ribs on the case and the perforated plate, whereby the meat may flow outwardly beyond the outermost inner walls of the case and at the same time inwardly to a point adjacent to central hole or journal-bearing in the perforated plate.' The outer limits of the perforations in the plate'20 are indicated by broken lines in Fig. l. The shape of the knife-blades in end view at their outer ends is clearly shown in Figs. 3 and 5%. When the forcerhastwo short threads, it presents the form-of a modified triangle in` end view, as shown in Fig. 2, the grooves between the threads extending to the delivery end of the forcer, although quite shallow at the said end; In the modication shown in Figs. 7 to lO, inclusive, I give only one short'thread to the forcer A', which terminates diagonally opposite themrft'i thread, as shown in Fig. 7. form'thsamc journal or shaft 9 at the outer end and employ twdahvgulardrivingportions 10 and 10b in dierent'sizes. The two knives or two sets of

knifeedges

27a and 28a are formed in two separate pieces. The knife 28,a has only two knife-edges arranged diagonally opposite to correspond with the terminal ends of the two threads on the forcer, and its hub 25a has an angular socket 26, Fig. 10, to fit the angular driving portion l0" of the forcer. Its hub may also be recessed, as at 29, if desired. It is also beveled or chamfered olfon its outer face to permit the material'passing it to work inwardly; but I make two breaks 30 in this bevel for the back of two of the blades that carry the edges 2.7a to `rest upon. This outer knife 27a has four blades, and its hub 3l has an angular socket '34, that fits the driving portion 10b. These knives or two sets of knife-edges, like the extend inwardly so nearly to the center of the perforated plate as do the knife-edges 27 trst described. By reason of the angular form of the driving portions 10a lOb in two sizes and corresponding sockets in the knife-hubs it is impossible to wrongly assemble these knives. The series of knife-edges arrangedin two sets in one piece or in two separate pieces are considered as equivalent-s, excepting in cases where the integrality of the two sets is particularly mentioned, and the numberin each set is immaterial, solongas there is at least one knife-edge in each set.

In both constructions as the meat reaches the enlarged space between the ribs'at the flaring end of the case it spreads outwardly and fills the outwardly-tiaringspaces between vthe forcer and within the diameter of that side of the hub that bears against thel ribs. The constructionis simple, while the machine is efficient. The clamping-ring for the perforated plate acts to adjust one set of knifeedges properly against the face of the perforated plate and the other set'againstthe ends of the terminalI portion ot the ribs.

Itis apparent that some changes from the specic construction herein disclosed maybe madeand therefore I do not wish to be understoodas limiting myself to the precise form of construction shownand described, but desire the liberty to make such changesin working my invention Vas may fairly come within the spirit and scope of the same.

claim as my invention- I l. The combination of the case having internal ribs that terminate in end cutting-faces,

with the forcer, a knife-edge rotating with the saidforcer, extending outwardly beyond the periphery of the said forcer and across the ends of the said ribs against whichit end of the "case and having its cutting area extending both outwardly and inwardly to said knife-edges to the said stationary cutter and also to she end cutting-faces of the ribs. 2. The combination of the case having a IOC IIO

cuts, a stationary cutter mounted in the outer cylindrical body with an outwardly-enlarged delivery end, and internal ribs extending over the said cylindrical and enlarged portion with the tops of the ribs forming a cylindrical bore throughout the length of the interiorly-ribbed portion of the said case, the ends of the said ribs having cutting-faces, with asubstantially cylindrical screw-forcer, a kni fe-edge rotating with the said forcer at the end thereof and acting on the said end faces of the said ribs, a stationary cutter mounted in the delivery end of the said case and havingacutting area that extends both inside and outside the diameter of the said forcer, and a knife-edge rotating with the forcer and acting on the inner face of the said stationary cutter.

3. The combination of the case having interior ribs, the ends of which form cuttingfaces, with a rotary forcer, a knife-edge rotating with the said forcer and extending across the said cutting-faces, a hub for the said knife-edge mainly of a larger diameter than the smallest inner diameter of the case at the said cutting-faces, a stationary cutter mounted in the delivery end of the said case, and a knife-edge acting on the inner face of the said stationary cutter, the said knife-edge extending inwardly to a point inside of the inner diameter of the said end cutting-faces of the ribs, whereby the meatis mainly forced7 iirst outwardly beyond the diameter of the forcer, and then part of it permitted to iiow inwardly within the diameter of the forcer'.

4. The combination of a case having interior ribs the ends of which form cutting-faces, with a rotary forcer, a stationary cutter mounted in the end of the said case and knifeedges rotating with the forcer and acting on the said stationary cutter and end cuttingfaces of the said ribs, the cutting area of the said stationary cutter and coacting knifeedges extending both outside and inside the inner diameter of the said end cutting-faces of the said ribs.

5*. The combination of a case havinginternal feeding-ribs with the spaces between. the said ribs enlarged outwardly at the delivery end so as to be of a greater depth at the ends of the said ribs than at any other portion of the case, the said ribs having cutting-faces at their ends, with a forcer rotating within the ribbed portion of the said case and having grooves that extend through to its delivery end, and a cutter having a hub mounted on the endv of the said forcer to rotate therewith and act upon the ends of the said ribs,`

the said cutter having its hub recessed adjacent to the inner end of its cutting edge to a point that describes a smaller circle than the circle of the inner faces of the said feedingribs at their cutting ends.

6. Theeombination of the case having interior ribs the ends of which form cuttingfaces, with a forcer, a knife-edge rotating with the said forcer and acting across the said cutting-faces of the ribs, a perforated plate at the delivery end of the case, and a knife-edge rotating with the forcer and acting on the said plate, the inner end of the said knifeedge and innermost coacting holes in the said perforated plate extending inwardly beyond the inner circle of the said ends of the ribs.

7. In a meat-cutter, a compound knife having cutting edges on opposite sides for coacting with other cutters, and a central hub integral with the said cutting edges into which hub the cutting edge or edges on one side merge, the cutting edges on the other side extending farther inwardly on the side face of the said hub.
