The shape or cross-section of the periphery of the knife will be clear from Figures 3 and 8. The plane of the knife, as shown in Figure 3, is somewhat tilted in relation or, more correctl from the plane of the provided with a forward face face E", the latter being shown as concave or may also be" tracks K along which travels the meat ca rriage' 'generally. indicated as K which will later be described in somewhat greater detail.

Note, with referenceto Figure 4, that the knife or razor bla'de member H depends a considerable distance below the edge of the E and L near-- knife, thus serving as a discharge member for dropping ordepositing grease and small particles inthe trough H which is positioned. in the frame or ,base beneath the edge of'the knife and the said scraper members and may be withdrawn'for exampleby the handle H for cleaning. Note that the edges of the trough H are received in recesses Il -E in order that there may be no space about the trough into which grease or fragments. of material can penetrate. I Also the lower edge of the member H depends to a point beneath-the upper edge of the walls of the troughH thus limiting the discharge of material to-the space within the trough and reducing to a minimum the tendency of the material discharged to reach any point outside of the interior of the trough. The result isa maximum efficiency of the cleaning action of the opposed scrapers and the reduction to a minimum of the tendency of grease and small fragments to be carried intoithe interior of the knife and H transmission housingor space. Note, as on reference to Figures 1 is provided in'the frame, which recess overlies the opentop of the tray H The periphery of the knife closely approaches the top of the recess and the scraper H penetrates the recess, v j The work tray K includes the plane hor izontal portion K and the upstanding edge portion K member K farthest from the knife when the carriage. is in withdrawn position. As shown at the left of Figure 1 the inner edge of the-carriage closely approaches the cutting arc of the knife and lies parallel with the path of movement of the carriage. j
It will be realized that whereas I have operative device, nevertheless 'many. j changes might be made in size, shape, number and disposition ofparts without departing from the spirit of my invention. I therefore wish my description and drawings to be taken asina. broad sense illustrative and lying. along the edge of the.
meat is being cut. If a piece of ham or bacon is sliced the extremely rapid movement of the travel of the knife through the bacon generates suflicient heat to hold a certain proportion of the grease from the bacon.
grease adheres to the knife and is car-' ried by the knife within the housing or space to the rear of the guard plate and is spattered or deposited therein. The result is an extremely unsanitary condition, as the interior of the housing is inevitably hard to clean.
In applicants device the amount-of larding is greatly reduced and the deposit of grease and small particles within the housing is practically entirely eliminated. The hollow grinding of the knife provides a very thin blade at the point of initial contactor cutting operation and the resultant friction is substantially less, and therefore the heat is less than when a blunt or more obtusely angled blade is employed. The result is an initial decrease of larding.
Finally the arc ofthe knife, the hollow ground or concave portion E, tends to peel or curl the slice away from the face of the knife, thus limiting the engagementof the slice with the rear of the knife and reducing friction of the slice against the knife.
Assuming that the deposit of particles on the knife and the deposit of grease on the knife cannot be entirely eliminated, as is the case, the scrapers provided serve to remove from the knife substantially all of the grease and particles carried thereby. The forward scraper H with its thin blade H which is shown as inclined in relation to the radius of the knife, clear the fiat face E of the knife. The inclination oflthe blade tends to carry the grease and particlesdownwardly to the.
lower corner or edge of the plate, which lower corner lies within the hollow of the trough or drawer H The material from the opposite side of the knife is gathered by the scraper H, which conforms to the contour of the knife and which is positioned slightly in back of the scraper H, H It does, however, depend below the edge of the knife and it, when taken in connection with the opposite scraper, thoroughly cleans this face of the knife, all the, material so cleaned drop-ping inthedrawer H I 1 The space between the housing 'G and the guard plate B is thoroughly protected against access of material. -Referring to the front 1 of the knife the guard plate-,B', sittingin' the recess-E, gives thorough protection; As to the rear of the, knife the, offset portion E of the knife overlaps-or extends outwardly beyond the-edge G of the bell deflector G.
Also the inner edge G? of the bell' deflector extends outwardly beyond andoverlaps the opposedfiange C of. the. hub C in which the knife bearing assembly is mounted. The hub C however, is continuous with the frame portion C, and a complete closure is thus provided.
The bell deflector G is automatically centered in relation to the knife and knife shaft, since it clamps about the exterior of the. bearing sleeve D, being held in position by any suitable screw or locking means G The bell deflector is therefore inevitably concentric with knife and knife shaft and needs no separate adjustment.
D D the sleeve D and the bell deflector secured to the outside of it is inserted as a unit into the space G and is locked in position at the downward point for example by upright member K at the rear of the carriage prevents the formation of any rag or tail on the material being sliced.
he knife assembly, including the knife shaft, the ball races goo It will be observed from Figure 3 that the hollow ground or exposed portion of the rear face of the knife and the bell deflector G and the hub C form, in horizontal axial cross-section, a generally. concentricarc, or a continuous and more or less arcuate surface. These members entirely close the space to the rear of the knife and the slices,
as theyare cut and curl from the back of the knife, cannot penetrate to the rear of the knife within the housing, and find no interrupting or interfering projection against which they abut, but drop freely to whatever receiving means are employed.
I claim:
1. In a slicing machine, a supporting frame, a rotary knife, a knife shaft therefor, a bearing sleeve about said shaft and frame, a rotary knife, a knife shaft therefor, a drivevpu'll ey associated With said shaft, :1. bearing sleeve about said shaft, a guard member inounted about said shaft and sleeve and extending forwardly about said pulley and toward the rear face of the knife, the knife shaft, pulley sleeve and guard being removable as a unit from the slicing machine frame.
