MACHINE COMPANY, or CHICAGO, ILLINOIS, A CORPORATION on NEW YORK SLICING MACHINE Application filed September 8, 1930. Serial No. 480,396.

My invention relates to improvements in slicing machines and has for one purpose the provision of improved means for supporting the slice at the time of its severing from the body of the work; Another objectis the provision of improved means for deflecting the slice, away .from the knife wh ch cuts it.

I Another object. is the provision of improved means for delivering slices cutby the rotary knife to a receiving tray. V

Other objects will-appear from time to t me in thecourse of the specification and claims.

My invention is illustrated more or less diagrammatically in the accompanying drawings, wherein:

Figure 1 is a plan View;

Fig. 2 is a rear elevation;

Fig. 3 is a section'on line 33 of F1g. 2;

Fig. 4 is a section on the line 4-4 of F g. 2;

Fig. 5 is a section on the line 55 of Fig. 4;

Fig. 6 is a detail; and

Fig. 7 is a partial horizontal section through a variant form. 1

Referring to the drawings, A generally 1ndicates a base portion upon-which may be mounted in any suitable manner, a motor A with a motor shaft A and a pulley A A indicates a belt extending about a pulley A? on the knife shaft A. I, y

B indicates a rotaryoknife mounted on the knife shaft A and forwardly recessed as at B and rearwardly as at B g V C indicates a guard plate masking a forward face of the knife. The knife is protected from the rear by the frameor housing portion C upwardly projecting from the base A. Formed with or mounted upon this frame portion O is the bearing sleeve C in which the knife shaft A is mounted. This bearing sleeve C is forwardly flared or ex panded as at C to terminate in an arcuate lip C which penetrates the rear recess B of the knife as shown, for example, in Figs. 1, 3, 4 and 7.

1) generally indicates a gauge plate which may be mounted on any suitable support generally indicated as at D D indicates a rotary knob whereby, through any suitable gearing or drive means the support DPand gauge plate D may be moved Into and out of and rearwardly away from the cutting plane. Underlying the gauge plate D is a slice support D in the form of an extended bar. This bar includes or has mounted thereon an elevated portion D adjacent the closest approach of the bar to the cutting edge of the, knife. This raised portion D extends upwardly above the normal level of the top of I the bar D It is to be seen, as in Fig. 4:, that an end of the bar portion projectsinwardly past the periphery of the knife as at D, this end D being more or less curved or spaced outwardly away from the rear face .of the knife. Preferably the curved portion D eX- tends or curves from the cutting edge of the knife, closely approaching the knife at the cutting edge and being spaced laterally. therefrom an increasing distance progressively toward the center ofthe knife. This form of the disposition will be clear from Fig. 4. The bar D is also provided with a recess or downwardly and outwardly cut-away and beveled or curved portion D This cut-away portion permits the severed slice to clear or drop below the level of the raised portion or supporting abutment D and also deflects the slice away rom the rear face of the knife.

In order to receive the slice after it issevered, I provideany suitable receiving tray E, the details of which do not of themselves form part of the present invention,-but which is formed as at E closely to approachthe cutting plane. In. order to support the ma-- terial to be sliced, I provide any suitablecarriage structure generally indicated as G which rides along the circular supporting rail G and the rectangular guide rail G G G indicate downward projections or tongues from the carriage structure G which engage also sides of the guide track G as by the adjustable members G. G indicates a work support positioned upon the carriage G. Preferably the level of the upper surface of thework support is substantiallyeven with the top of bar D The member 1) projects above the surface of the bar D and also above the surface of the support G The edgeof H which may be secured as by the screws H to the enlarged portion C3 of the sleeve C Mounted at the outer extremity of the bracket His a deflector generally indicated as H the forward end H of which may approach or contact the end of the slice support which is beveled or cut away as at H adjacent the forward end of the projection D.

It will be realized that whereas I have shown and described a practical and operat ing device, nevertheless, many changes may be made in size, shape, number and disposition of parts without departing from the spirit of my present invention. I wish my drawings, therefore, and my description to be taken as in a broad sense illustrative or diagrammatic, rather than as limiting me to my particular description and disclosure in detail.

The use and operation of my invention are as follows I find it preferable to support the slice at the point of severance and an efficient method of supporting it is to employ an upward projection such as the member D which lies in part-on each side of the cutting plane. This projection D provides a positive support for the work at the point of severance and for the slice as it is being severed. As soon as the slice is actually severed it should be permitted to drop to clear from the rear of the knife.

, This is important in order to prevent adherence of the slice to the rear face of the knife. The result of such adherence may be damage to or breaking up of the slice and bleeding of the material. In order to effect this free drop and guide action, I have cut away the end of the bar as at D or provide a similar cut-away portions H and H in connection with the deflector H The slice, therefore, drops, its edge being free to drop, and engages the cut-away portion D or H This downwardly and outwardly curved or 'inclined cut-away portion tends to throw the slice outwardly away from the knife and it is, in practice, discharged on the tray E an inch or more away from the cutting plane. In order to prevent any interference with the slice as it is severed, I find it preferable to form the portion D of the bar D in such fashion that it approaches the cutting edge only at the cutting point and recedes rapidly therefrom as shown in Fig. 4%. This prevents any tendency to wedge or catch the slice or fragments of sausage casings and the like between the knife and the member I). The

I deflector H is similarly formed and spaced.

The grease and small fragments which may knife and means for rotating it, a carriage and means for conveylng said carriage past the cutting edge of the knife, a slice and work support positioned adjacent said carriage adapted to support the work and slice at the point of severance, and deflector means adjacent said support adapted to deflect the severed slice, said deflector means being closely adjacent but out of contact with the rear face of the knife, and being separated therefrom by a distance increasing progressively in wardly from the periphery of the knife, the approach of the deflector to the knife at the severing point being close.
