Application filed November 3, 1916, Serial No. 129,364.' Renewed August 24, 1918. Serial No. 251,338.

To all whom it may concern:

Be it known that I, BURTON A. TYLER, a citizen of the United States, residing at Cambridge, in the county of Henry and State of-Illinois, have invented certain new and useful Improvements in Fat-Gutters, of

which the following is a specification.

This invention relates to new anduseful improvements in fat cutters for cutting up the fat of hogs and cattle preparatory to treating the same in rendering kettles.

The primary object of this invention is to provide a machine of this character which will greatly facilitate this work.

A further object of the invention is to provide a machine of the character specified which is comparatively simple and economical in construction, efficient in operation, and in which the parts may be readily assembled or disassembled.

With the foregoing and other objects in view that will appear as the nature of the invention is better understood, the same consists in the novel features of construction, combination and arrangement of parts illustrated in the drawings and more particularly pointed out in the appended'elaims.

In the accompanying drawings Figure 1 is a central vertical longitudinal section of a machine embodying my improvements. V

Fig. 2 is a vertical transverse section taken on the plane indicated by the dotted lines 2-2 of Fig. 1, looking in the direction indicated by the arrows.

'Fig. 9 is a vertical transverse section taken on line 99 of Fig. 8, looking in the direction indicated by the arrows.

Fig. 10 is a similar view, taken on line 101O of Fig. 8, looking in the same directiona V,

Fig.11 is a partly plan and partly hori zontal sectional view of the form of machine shown in Fig. 8 and Fig. 12 is a detail sectional view on line 1212 of Fig. 11.

Referring to the drawings for a more particular description of the invention and which drawings are for illustrative purposes only and therefore not drawn to scale, the machine comprises a substantially rectangular oblong casing 1 provided with an outwardly flared mouth 2 and open bottom 3, the purpose of which is apparent. The right hand end wall as l, of the casing is also provided with a removable plate 5 which is held in place by the screws 6 or other equivalent means and which facilitates the introduction or removal of the knife carrying cylinder and associated parts.

The knife carrying cylinder 7 which is arranged or disposed longitudinally in the casing and extends the full length of the machineis provided at opposite ends with the reduced

bearings

8 and 9, which are journaled in

bosses

10 and 1 1 formed, respectively, with-the end wall 12 at the left hand end of the machine and the removable end plate 5.

i The bearing-9 of the cylinder projects beyond the end plate 5 and has applied thereto the crank handle 15 for turning or rotating the cylinder, and the latter is held against endwise movement and the crank handle held in place by the

thumb screws

13 and 1 1 which screw into corresponding interiorly threaded openings in the cylinder.

' In carrying out the invention, the cylinder is provided throughout its'length with a pair ofcorresponding longitudinal dovetail grooves which are disposed diametrically opposite each other and receive the knife supporting bars 16. Said bars 16, which are also of dovetail form in cross section, are formed with flat inner faces 17 andarcuate outer faces 18 which lie flush and conform with the curvature of the outer surface of the cylinder, as shown.

Each knife bar is provided throughout its length with a series of longitudinally spaced cutting knives 19 formed with cuttlng edges 20, said knives being of fiat substantlally rectangularoblong form and arranged n endwiseor perpendicular relation with sald knife bars and cylinder. Said cutting lmives are removably secured to the knife bars by thefollowing means. Each knife is provided at its inner end adjacent the cutting rectly opposite each other.

edge 20 thereof with an inwardly projecting threaded stem 21 which passes through a corresponding transverse aperture 22 in the knife bar and is also provided at said end behind said stem with 2. lug 23 which fits in a corresponding socket 24 in the latter and holds the knife against turning in the arc of a circle in either direction with the stem as a pivot, the sockets 24 being arranged in the outer faces of the knife bars behind and in transverse alinement with said apertures 28.

Nuts 25 screw on the outer ends of the stems 21 against the inner or bottom faces of the knife bars to hold or secure the cutting knives' in removable position.

Each series of cutting knives are arranged in alinement or diametrically opposite those of the other series and the knife bars are removably secured to the cylinder by the fastening screws 26.

The machine further comprises a pair of slicing knives 27 which extend longitudinally of the machine and at right angles with the cutting knives 19, said slicing knives extending approximately the entire length of the casing and being disposed di- The slicing knives, which are of curved or arcuate form in cross-section, are removably secured to the cylinder 7 in spaced relation therewith, by the end and center supports 28 and 29, respectively, which are secured to the cylinder at right angles with the cutting knives. The end supports 28, which are in the form of flat metal strips, are secured at their inner ends by the screws 30 or other equivalent means, to the ends of the cylinder 7 and are provided at their outer ends with the inwardly and right angularly bent portions 31 which are removably secured to the ends of the slicing knives. The center supports 29, which are of tapering form in cross-section and provided with cutting edges 32 to prevent clogging, are provided attheir inner ends with threaded stems 33 which screw into corresponding sockets in the cylinder and have secured to their outer ends by screws 34 or other equivalent means the slicing knives 27.

The casing 1 is provided upon the inner surface of one side wall, as 35, thereof with a series of longitudinal vertically spaced cutting ribs 36 which cooperate with the slicing knives 27 in cutting or reducing the fat into fine particles.

In the modification illustrated in Figs; 8 to 12, inclusive, of the drawings, the knife supporting cylinder 7 is formed of a series of longitudinally spaced cylindrical sections 37, each section being formed or provided at one end with a pair of transverse oppositely disposed spaced V-shaped projections 38 which fit in corresponding grooves in the adjacent section and whereby the respective sections are interlocked with each other and held together as a unit against relative turning movement. The cylinder sections are provided each with a central bore or opening 40 to receive a supporting shaft 41 which extends longitudinally throughout the. entire length of the machine and is threaded at opposite ends, as at 41, for;threaded engagement with the tubular bearing sleeves or nuts 42 formed preferably with hexagonal heads 48 which fit between the inner faces of the end walls of the casing and the outer ends of the end sections 37 of the knife supporting cylinder and hold the former in contact and secure interlocking engagement.

In this form of the invention, I dispense With the knife bars 16 and knife supporting means shown in Figs. 1 to 7, inclusive, and form each pair of upper and lower or transversely opposite cutting knives 19 from a single bar or piece, as 44, by forming this bar at opposite ends and diagonally opposite edges with cutting

edges

45 and 46. The bars 44 are provided with central openings or apertures 47 and are threaded on the shaft 41 between the cylinder sections 37 which are formed in one end with transverse recesses 48 to receive'said bars and whereby the cylinder sections are permitted to fit in contiguous relation. 5

Also, in this form the end supports at each end of the machine are formed in one piece or bar, as 49, said bars extending across the ends of the cylinder at right angles to the plane thereof with the intermediate portions fitting in transverse recesses 50 in the outer ends of the end sections of the cylinder.

The center supports are also formed in one 5 bar or piece, as 51, which also extends across the cylinder at a point centrally or approximat-ely centrally of the length therof, with its intermediate portion fitting in a corresponding transverse recess 52 formed in one end of the adjacent cylinder section at right angles to the knife bar receiving recess 48 in the opposite end thereof. It is thought that the form of machine illustrated in Figs. 8 to 12, inclusive, and last described will be cheaper or more economical 111 construction and equally as eflicient in operation as the form. shown in Figs. 1 to 7 inclusive.

While my machine is primarily designed as a fat cutter, I claim the right to use the same for cutting or reducing meat or other substances into fine particles.

Various changes in the. form, proportions and minor details of construction may be resorted to without departing from the principle or sacrificing any of the 'advantages of,

this invention as defined in the appended claims.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is i 1. A machine of the character specified comprising a casing, a knife carrying cylinder revolubly mounted therein, one or more series of longitudinally spaced cutting knives, removably secured to said cylinder, means for rotating the latter, one or more slicing knives removably secured to said shaft in spaced relation therewith and at right angles with the plane of the cutting knives and a series of longitudinal vertically spaced cutting ribs formed on the inner face of one side wall of the casing and cooperating with the lmives in cutting or reducing the fat or other substance into fine particles.

2. A machine of the character specified comprising a rectangular oblong casing, a knife carrying cylinder arranged longitudinally of and revolubly mounted in said casing, knife carrying bars removably secured to the cylinder at diametrically opposite points, a series of longitudinally spaced cutting knives removably secured to each knife bar at right angles or in perpendicular relation with the cylinder, slicing knives arranged longitudinally of and extending the full length of the casing in spaced relation with the cylinder, said slicing knives remov ablysecured to said cylinder at right angles with the plane of the cutting knives, means for rotating the cylinder, means for removably securing the slicing knives to the cylinder and a series of longitudinal vertically spaced ribs formed on one Wall of the cas ing and co-acting with the cutting and slicing knives in reducing the fat or other substance into fine particles.

In testimony whereof I affix my signature in the presence of two witnesses.
