Application filed June 18, 1908. Serial No.489,1'79.

To all whom it may concern:

Be it known that I, JAMES J. FARQUER, a citizen of the United States, residing at Danville, in the county ofHendricks and State invented certain new and useful Im rovements in Cutters and Shredders of w ch the following is a specification.

T invention relates to machines for chopping, slicing, shredding, cutting and reducin various materials, such as roots and vegetab es, meat, and lard .preparatory to rendering and other materials that are to be reduced or c'omminuted.

.The invention has for its object to provide a simple and improved machine by means of which the materials operated upon shall be subjected to several cutting operations at various angles.

A further object of the invention is to provide an improved feed mechanism whereby the material operated, upon s all be presented to the cutting apparatus positively and with-perfect regularity.

A further object of the invention is to improve the cutting mechanism, and to provi 0 means for preventing the material that is to be operated upon from adhering to the knives or cutters.

simplify and improve the construction and operation of this class of devices.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts, which willbe ticularly pointed out in the claims.

In the accompanyingdrawings has been illustrated a simple and preferred form of the invention; it being, however, understood that no limitation is necessarily made -to the precise structural details therein exhibited, but that changes alterations and modifications within the scope of the claims -ma[y be resorted to when desired.

chine consists of an ob ong box B, of suitable dimensions, said box being com osed of

side pieces

5, 5, front and rear en ieces- 6, 7, and a transverse partition 8. e latter serves to support an inclined feed-board or table 9 having upon its underside a transverse cleat 10, abutting upon the cross-piece or partition 8, adjacent to the upper edge of the latter; the forward end of the feed-board being disposed in contact with the inner face of the front cross-bar 6 of the casing.

suitable inclined position in suc that it ma be very readily pu oseo washing and cleansing the same.

e side members 5 of the casing are rovided with bearings for the transverse shaft 11, carrying the feed roller 12' another shaft 13 1S sup orted for rotation above and adjacent to t e feed roller 12 carrying a plurality of circular knives or cutti'n disks 14, which are s aced apart by the col are or washers 15. T shaft 13 is screw-threaded adjacent to its ends, and is provided with nuts 16, and washers 17 where y the cutters 14 and the collars 15 are firmly secured upon said shaft. The feed-roller 12 is provided with a plurality of annular grooves 18 that are engaged by theperi heral edges of the disks or cutters 14.,whic latter are of such dimensions that the ed es will project into the annular grooves of t e feed roller. The latter, which is arran ed in such a position that the inclined fee -table will be nearlv tangential thereto, and which is accord ingly ada ted to receive the material passin over the eed table, is provided with radia extending teeth or spurs 19 said teeth or spurs being disposed in annular series intermediate the spurs are for t e pur ose of enga ing the material that is to be s iced or shred ed, and positively conveying such material in engagement with the cutting mechanism- 8, manner meshing with a pinion 21 upon the cutter carrying shaft 13, which latter willthus be rotated at a speed exceeding that of the shaft 11; the speed being regulated by the relative dimensions of the

gear wheels

20 and 21. The shaft 11 has been illustrated The frame of casin of the improved ma- Said-feed-board will thus be supported in a removed for the rooves 18; these teeth or The shaft 11,- carries a spur-wheel 2 0.

' of w'hic as b'ein e ui ed withacrank 22 b means i1 it in ay be rotated; it is bvious, however, that said shaft may be provided with a band-wheel or other means for receiving motion from any suitable source of power, such as an electric or mechanlcal motor of any well-known construction.

The side members 5 of the frame are provided with seats supporting the ends of a transversel dispose cutter bar 23, which is arrange directly in the rear of the feedroller 12, and as closely adjacent to said feed roller as possible without interfering with the operation, the front edge of the cross-bar 23 is preferably provided with notches 24 for the passage of the teeth or spurs 19, thus "enablin the front edge of said cross-bar to be p aced practically in contact with the surface of the feed roller;

the rear edge of the bar 23 resents a cutting edge 25 which co-acts with spiral knives or cutters 26, supported by 'the disks 27,upon a shaft 28 that is mounted for rotation the side members of the frame .directly 1n rear of and adjacent to the feed-roller. The

shaft 28 carries a pinion 29 meshing with the spur wheel 20 upon the shaft 11, whereby motion is transmitted to the shaft 28 carrying the s i'ral knives or cutters.'

Hinge y connected with the side members 5, of the frame or casing is a hood 0, the side members 30 of which cooperate with the side members 5 of the casing to form boxes or bearings for the .cutter-

car ing shafts

13 and 28; keepers 31 have een shown for the purpose of assisting in securing the shaft 13 in osition for'coperation, but it will be observed that by raising or lifting the hood 0, both of the

shafts

13 and 28 are convenientlly accessible, and capable of being remove from their respective bearings, thus enablin the knives or cutters to be conveniently cleansed and sharpened when necessary. The cross-bar 23 is likewise very convenientliy accessible, and capable of being remove from its seats, and the'feed roller may thus be completely exposed for convenience in cleansing the machine which, as will bereadily understood, is a matter of considerable importance. The hood is provided with a cross-bar 32, to the under side of which are attached a plurality of flat leafsprin s 33 normally occupying an approximate y horizontal position and extending forwardly from the cross-bar 32 in the direction of the circular knives or cutters 14, and

between the latter; the leaves or springs 33 being of a width equal to the width of the spacesbetween the knives or cutters; the leaves or springs 33 may thus be re arded as" constituting scra ers that engage t e knives or cutters for t e purpose ofkeeping the latter clean and free from adhering materiaL of any kind. For the purpose of preventing accidental displacement of the springs 33,

mates there may be secured upon the front side of the cross-bar 32 a plate or comb 34, having teeth 35 that extend irito the s aces between the springs 33; the latter, which are referably secured u on the cross-bar 32 by astening means suc as ordinary stud-screws 36, are thus revented from twisting or turning upon sai screws so as to overlap one another manner as to make it inconvenient to place them in proper relation to the cutting disks 14.

From the foregoing dipription taken in connection with" the dr wings hereto annexed, the o eration andhtdvantages of this invention wil be readily understood.

'or otherwise become misplaced in such a As reviously stated, the improved device may e utilized for the purpose of cutting, chopping, slicing or shreddmg materials of all inds. Materials clined feed-board will e seized y the teeth or rongs of the feed-roller and will be carrie by the latter -.in engagement with the circular knives or cutters, whereby the material is divided into narrow strips or slices; these strips or slices will be delivered b the feed roller onto the cross-bar 23, an the spiral knives or cutters 26 co-acting with said cross-bar'will cut or chop the strips or slices at approximately right-angles to the revious cut, thus chopping the strips into ragments of the requis1te size. It will also be readily seen that the strips or slices while being operated upon by the spiral cutters, are still positively fed by the feed roller, the radiall rojectin teet or spurs of which retain o d of sai strips 01"811065 as long as the latter extends between the circular knives 14.

The general construction of the improvedmachine is' simple and inex ensive, and it will be found thoroughly useful and efficient for the pur oses for which it is provided.
