SLICING MACHINE.

Application filed April- 13, 1928. Serial No. 269,705.

My invention relates to a slicing. machine and particularly to a slicing machine having a rotary knife and means for driving it, of the type wherein a work supporting carriage is provided and means for guiding itacross the face of the knife. One object of my invention is to furnish a support for the slices which are being cut. The presence of such a. support, which holds the slice in the plane of the larger piece from which it is cut, insures a uniform and efficient severance of'the slices from the piece, prevents ragged slices, and prevents slices from being partially severed. A clear, complete cut is insured. Another object of my invention is'to prevent the slices from falling into the space between the gauge plate and the carriage, and to insure that each slice cut shall pass through the space between gauge plate and knife to the trough or receiving means. Other objects will appear from time to time in the course of the specification and claims.

I illustrate my invention more or less diagrammatically in the accompanying drawings, wherein Figure 1 is .a front elevation;

Figure 2 is a section on the line 22 of Figure 1 Figure 3 is a section on. line 33 of Figure 2; and

Figure-4 is a detail.

Like parts are indicated by like symbols throughout the specification and drawings.

A indicates any suitable slicing machine base I member having the ground engaging supports or studs A B generally indicates any suitable housing member or body upwardly projectin therefrom having associated therewith a face plate B normally fixed in position and a gauge plate 13 which may be moved toward and away from the plane of the knife as for example by rotation of the knob 13". I do not wish to be limited to any particular means for imparting movement to the gau e plate but-I have herein shown lugs B on t e rear of the gauge plate, levers or arms B pivoted thereto, themselves pivoted as at B, a gear B" associated with one of said levers and a worm B in mesh therewith and actuated by the knob B. Y

C indicates the knife, it being herein shown as recessed .in its forward face as at C in order to permit the peripheral portion C to project outwardly into and slightly beyond the planes of the face plate B It will upon the supports D Beneath it is a supplemental track D herein shown as of rectangular cross-section. D indicates a carriage slidable along the track D, provided with a downward extension D formed to surround the track D and thus to prevent rotation of the carriage D about the track D. D is any suitable manual handle whereby the carriage may be moved along the track D. D is any suitable material carrying tray positioned upon the carriage D Unless the gauge plate B is adjusted so far forward as to lie practically in the plane of the cutting edge of the knife C there will be a space between the gauge plate and the carriage plate D. If this space 1s left open, bits or slices of material may under some circumstances drop therethrough instead of passing through the space between the knife edge C and the opposed arcuate edge of the gauge plate. In order to render this impossible and to insure that all slices shall pass through such gap I provide a supplemental horizontal ledge or plane surfaced member, to prevent such slices from dropping down between the gauge plate B and the carrier plate D.

As shown for example in Figure 3 I illustrate this member as a flat horizontal shelf E'with an inward extension E which may be mounted for exam 10 upon any suitable support E upon the flame of the machine. E is an extension to the right, as shown in Figures 2 and 4, which is cut awa or formed as at E in order to hug the rear 0 the peripheral portion C of the knife. The portion E proper is aligned with a horizontal slot or aperture E in the face plate in such fashion that the face plate may be freely adjusted. The gap between the edge of the plate E and the carrier plate D is so thin that no fragment or slice of material of any substantial thickness can pass therethrough. Preferably the upper level of the shelf E is at the same height or even slightly higher than the top of the plate D.

For example, as shown in Figures 2 and 4, I may make a shelf member E adjustable to- Ward and away from the knife edge, as by the employment of the slots E through which pass the locking or adjusting screws E.

It will be realized that whereas I have de-- 'knife, and in employing the gauge plate against which the work is thrust, whether manually or mechanically, it is important to support the slice while the slice'is being cut. Were it possible, which it is not, to have the carriage approach so' close to the gauge plate that no interval is. left between gauge plate and carriage, there will be no necessity of supporting the slice in the front ofthe gauge .plate. However the mere fact that the gauge plate is adjusted toward and away from the path of the carriage insures that there will be a space between gauge plate and carriage.

And furthermore, the increase of the opening.

between the edge of the gauge plate and the cutting edge of the knife, which determines the thickness of the slice, insures that there will always be a space between carriage, gauge plate and knife at that point, in which the carriage ives no support. I therefore provide a shelf or su port which cooperates with the carriage and which is independent, in'its supporting function, of the position of the gauge plate.

' Referring to Figures 2 and 3 it will be clear .that the shelf E very closely approaches the edgeof the carriage, irrespective of the position of the gauge plate, the gauge plate of course being slotted to permit the passage of the shelf E ,therethrough. Therefore no slice or fragmentof meat can drop down through the space between the carriage and gauge plate.

Even more important is the lateral extension E of the shelf E, which is formed to hug the cutting edge of the knife. This insures that the slice, in course of severance,-

will be supported up to the instant of its com letion.

T e support at this point revents partially completed slices and litt e tail'ends of meat from-sliding down around the corner of the gauge plate and gettin between the front of the carriage and the nife.

In view of the frequent practice of using "vitreous enamel for carriage and auge plate the addition of the slice supporting shelf is plate prevents the last slice from falling down between the frontof the carriage and the gauge plate.
