JOHN' I. MCCORMICK, 0F CHICAGO, ILLINOIS, ASSIGNOR TO AMERICAN SLICING MACHINE COMPANY, 0F CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.
Application led March 24, 1911. Serial No.
T0 all 'whom it may concern Be it known that I, JOHN I. McCoRMrcK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Meat- Slicers, of which the following is a specification.
My invention relates to improvements in meat Slicers and is illustrated diagrammatically in one form in the accompanying drawing, wherein- Figure 1 is a side elevation of a machine with the device applied thereto; Fig. 2, a section along the line 2--2 of Fig. 1; Fig. 3, a section along the line 3--3 of Fig. 1.
Like parts are indicated by like letters throughout the several iigures.
The yclosed base A, from which projects the upwardly extending column or box A1, is provided with the tracks A2, upon which is mounted the reciprocating meat carriage A3, in opposition to the rotating knife on the shaft A5, mounted in the box A1. The carriage A3 is reciprocated and the knife rotated by means of mechanism within the base A, which is operated by the shaft A6 and fly wheel A".
B is a rotary diskshaped knife which has the beveled edge B1, the inner beveled surface B2 and the groove B3 intermediate the surfaces B1, B2.
C is a curved deiiector or scraper associated with the guard rail D from which latter inwardly projects two arms D1, D1, shaped as shown. Each is slotted at D2 to receive one end of the deiector C, and each end is held in position by means of the thumb screw D3. The inner ends of the arms D1 pass through apertures in the spacing rod E and are held in position. by the set screws E1,E1 in the end of such rod. This rod has an inwardly projecting arm E2 pivoted at E3 to the bracket E4.
F, F', are springs attached each at one end by the set screws F1, F1 to the spacing rod and at the other end to a pin F2 mounted in the bracket back of the pivot point E8 and above the same. On the inner end of the arm E2 is a notch G adapted to receive the dog G1 which is secured to the bracket by means of the slot G2 and screw G1.

. When the parts are in the position shown 1n full lines in Fig. 2, the guard is slightly in advance of and back of the rotating knife, the deiiector is in the groove of the knife and pressed thereagainst by the springs F, F. Its motion in that direction is adjustably limited by the dog G1 which can be set 1n position by means of the screw Gs in the slot G2. In this position,
ard and dei-lector are ready for use.
In the position shown in dotted lines, the movable guard and deflector,and in this form of the device they are associated together-are thrown outwardly so as to leave the knife edge free for grinding or cleaning, and they are held in this position by the spiral springs F because the engagement of the springs with the bracket at the pin F2 is back of and above the pivot point of the ard and deiector.
The use and operation of my invention are as follows: In operating the Slicer, with my device attached, the knife slices the meat in the usual manner, except that the deilector guides the meat and grease outwardly away from the surface of the knife, thus preventing the lodgment of grease and heat particles upon the body of the knife. The defiector being in engagement with the shoulder or groove at the rear of the cutting edge, effectively prevents the deposit of any foreign substance, such as small meat particles or grease upon the body of the blade and keeps it in a clean and sanitary condition. The fact that the edge of the deflector blade is located within the groove in the cutting surface obviates the need of any very close adjustment of the defiector and makes it possible to set the deflector in a predetermined position without making it necessary to compensate for irregularities in the knife. The deilector is held in position by the spiral springs which draw the lug on the'supporting arm over against the adjustable dog on the supporting bracket. that by adjusting this dog the positlon of the deflector may be varied to suit any style or thickness of knife. It will also .be observed that the deiiector strip may .e adjusted for different sizes of knife, 1n view of the fact that it is slidably held at either end the knife and its' It will be evident' which is carried by the supporting arms, is, partially removed from the cutting edge to in the supporting brackets. The guard,
permit the knife to operate, but at the same time is suiiiciently close thereto to protect the edge from contact with the clothing or fingers of the operatorf l I claim: v
1. A meat slicer comprising a rotary cutting knife and an adjustable normally xed blade in contact therewith, located adjacent and substantially concentric with the cutting edge and interposed between it and the center of the knife.
2. A meat slicer comprising a rotary recessed cutting knife and an adjustable normally fixed blade in contact with said knife and in engagement with the recess therein.
3. A delector for meat slicing machines, comprising a bracket, an arm pivotally mounted thereon, a spacing rod carried by said arm, arms adjustably mounted upon said rod and a delecting blade adjustably mounted upon said arms in contact with the knife.
4. A deiiector for meat slicing machines, comprising a bracket, an arm pivotally mounted thereon, a spacing rod carried by said arm, arms adjustably .mounted upon 1n sald recess but said rod and a deecting blade adjustably mounted upon said arms in opposition to the knife, elastic means for holding said blade in contact with said knife.
5. A deflector for meat slicing machines comprising a bracket, an` arm pivotally mounted thereon, a spacing rod carriedA by said arm, arms adjustably mounted upon said rod and a deflecting blade adjustably mounted upon said arms in opposition to the knife, elastic means for holding said blade in contact with said knife, and means for limiting the excursion of said blade.
meat slicer containing a rotary grooved knife and an adjustable and movable' deiiecting blade within said groove.
7. A exible curved deflecting blade for slicing machines and means for varying the radius of curvature of said blade.
