Be itknown'that I, AUGUST R. LUscHKA, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented acertain new and useful Improvement in Slicing-Machines,of

which the following is a specification.

' of Fig.- 23.

table A3 on -the guide rail A4.

My invention relates to improvements in slicing machines and is illustrated diagrammatically in one form -in the accompanying drawings, wherein-.-

Figure. 1 `is a vside elevation of fthe machine; 1Fig. 2 a section along the 'line2-2 of Fig. 11; 1g. 3 a section along the line 3-3 of Fig. l; Fig. 4 a sectionn along the line 4 4 Like parts are indicatedby like letters in the drawings. A v A The Ausual slicing machine base A, in -which ismounted the driving shaft 'A1 carrying the cran-k '-wheel A2 supports the reciprocating The vertical housing A5, boltedto the frame A, carries at .its upper end the sleeve A6 in which is screw vso.

threaded the bearing A?. .The rotary knife A8 is mounted on the shaftA9 inthe bearing A7 and is-d-riven by aUhai-nriding over the sprocket wheel A10 and driven from the drive shaft by any :suitable means. The bracket B, bolted -to the sleeve A, carries pivotally mounted thereon the hub B1 from which projects vthearm ,B2 and which has Vthe opposegiiat sides B3 in opposition to the plunger in the bracket B. The arm B.2 carries slidably mounted'in its outer end the rod C held in position by any suitable means and carrying the slidablc blocksv C1. The flexible curved deflector lC2 is supported at either end on one-of the blocks C1, being held thereon bythe screw C3 which also engages the rod C and holds the block in positlon. The rod C carries theourved guard C4 parallel with the -edge of the' knife and located just outside of and a little in front of thecutting edge. This guard isprovided at .its lower end with the extension C40 bent away from the knife andinwardly toward the carriage and terminating in a vdownward extension C? which engages the latch C6.

The latch C6 is mounted on a guard Dv l which is boltedA to the frame A and is llocated immediately in front of the carriage. .The

meat supporting foot or guide D1 is mounted on the guard D immediately in front of s'peeificatien ofmetters Patent.

. mounted on the' nut E by means of the screw- E3 carries the flexible scraper or deilector E4 made preferably of-fiberor some other v non-resonant material, and having the sharpened chiseled edge 'E5 in contact with the inclined back of the cutting edge of the knife along an approximately radial line. The'knife rotates-in a clock-wise direction-in rthe form as indicated, and therefore approaches the deflector downwardly and any particles which adhere to the knife will be scraped off by the deilector or scraper as the knifepasses the clfiseled edge;

' Izhave shown a device as adapted to a very well knowntype of slicing machine, but it will be quite evident that -it might be adapted to any `suitable form of machine, and I wish, therefore, that my drawings be regarded as in a sense diagrammatic.

The use 'and operation of my device are as follows: Vhen the driving wheel is turning, the knife` rotates and the carriage reciprocates back and forth in front of the knife, bringing the meat in the usual manner against the rotatingcutting edge. The meat slices pass between the cutting edge and the guard, and thus the guard protects the cutting edge against anything. but the meat, but does not interfere with its actionA upon the meat, in View 0f the factthat 'the guard is placed in front of the cutting edge in such manner that'there is spaceA for the meat to pass between it and` the kn. fe. The, ieXible curved deflector which is'carried by the guard supporting rod, contacts the knife along a curved line concentric with, but of slightly lesser radius than the cutting edge #of the knife and this deflector operates to 'turn the slice vas it is cut, awayfrom the knife and cause it to fall outwardly and downwardly into any suitable tray or pan.

This deflector thus prevents the passage of meat inwardly toward the axis of the lknife, and guards the central portion fthe knife and housing and prevents the itroduction.

of meat therein. The flexible fiber or hard vrubber chisel-'edged scraper whichvengages the inclined portion of the cutting edge-of the knife, is mounted. upon the same rod as the deiector and the guard, and its function is to scrape off of the knife blade any fine particles which might adhere to it, and otherwise would be carried into the knife housing where they `would be discharged by centrifugal force from the knife. Thus by means of the scraper and the deflectonwhicli operate inv unison and perform similar duties at different positions of the knife, the knife 'housing and the knife are kept entirely clean and Vfree from meat particlesv and grease which would otherwise accumniulate in the housing and decay. rI`he guard, deflector and scraper, being all mounted upon a central rotatably mount-ed vertical shaft, may conveniently be thrown out of opposition to the knife by merely rotating them. In order to do this, the downwardly projecting extension on the guard is lifted outwardly out ofthe latch or hook and the guard is then rotated, vcarrying with it the deflector and the scraper. The effective cutting edge of the knife is then exposed and may be cleaned.

A Then it is desired to use the knife again in a slicing operation, the deflector is vswung around until the downward extension strikes l the inclined portion of the latch, when it will, owing to its elasticity, spring into the latch hook and be held in position, thus compressing the scraper and delector against the back of the knife. These two parts are additionally held in position by the pressure of the spring-actuated plunger on the edge l of the flat `portion of the hub. They are therefore held against the knife by yielding 'means on either side.

The scraper I have indicated is made of fiber, wood, rubber or some other non-resonant material, since owing to the rapid movement of the knife and owing. to the necessary irregularity in its shape, also owing to the necessary excessive thinness of other such objects and materials, still' it is' quite evident that the same invention might equally well be applied to anydevice wherein rot-ary cutting or grinding wheels are used such as saws,'grinder's and thelike.

I claim: y

n a slicing machine thecombination of a rotary knife having a beveled cutting edge with an inclined scraper across and in con tact with -said edge and sharply inclined thereto and an arc-shaped deflector in close proximity to the knife at the inner margin of ,the effective cutting edge said scraperv A and deflector mounted so as to be simultaneously movable to and from the knife.
