SLICING MACHINE.

Application filed May 31,

.T 0 all 207mm it may concern:

Be it known that I, SoLoMoN IVILE, a citizen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Slicing Machines, of which the following is a specification.

The present invention relates to slicing machines and more particularly to the type in which the material to be sliced is presented to a rotary knife or cutter, an object of this invention being to provide a guard which will give proper protection for the user of the machine, and, at the same time, may be moved to a position where the knife may be readily cleaned. A further object of the invention is to provide for the cut material a tray or collector which will act as a guard for the knife.

To these and other ends, the invention consists in certain parts and combinations of parts, all of which will be hereinafter described, the novel features being pointed out in the appended claims.

In the drawings:

Fig. 1 is a front view of a slicing machine constructed in accordance with this invention;

Fig. 2 is a plan view;

Fig. is a detail view of the pivotal mounting for the lower end of the guard; and

F ig. 4 is a view of the spring for holding the shift-able guard portion in adjusted position.

Referring more particularly to the draw ings, 1 indicates the frame of the machine having a cutter or knife 2 rotatable thereon about an axis 3. The material to be sliced is held by a clamp 4 on a carriage or table 5 which is moved toward and from the plane of operation of th knife on a carriage 6 which is in turn moved back and forth past the cutting edge of the knife. For guarding the knife a guard member 7 is provided which preferably covers one half of the circumference of the knife being pivoted to turn about an upright axis 8 substantially vertically beneath the axis of turning of the knife or cutter, this being secured by providing a pivot screw connecting a lateral lug 9 on the guard member with a lug 10 formed on a bracket extending from the frame 1. It is apparent that this arrange- 1923. Serial No. 642,383.

ment permits the guard to swing outwardly to the position shown in dotted lines in Fig. 2. In order to hold the guard in guarding position, the latter may be provided with a lug 11 which through a screw 12 may be secured directly to the frame 1.

The guard member 7 carries a segmental guard member 13 which is slidable in an are on the guard member 7 at the one end of the latter, so that it may be projected beyond the guard member 7 to cover the blade above the effective portion of the latter. It is apparent that with materials of different thicknesses, a different amount of the blade should be exposed for the cutting action and this arrangement permits that portion of the blade immediately above the exposed cutting portion to be guarded. In this instance, the guard member 13 is provided with a guard slot 14 and through this slot a spring pressed collar 15 on the guard member 7 extends to obtain the dual function of guiding the guard member 13 and holding it frictionally in its different adjusted positions.

The guarding of the blade between the pivotal axis 8 and the effective cutting portion may be effected by a collecting tray or receptacle of novel construction which has a collecting wall 16 conforming to the curvature of the blade between these two points and extending horizontally beyond the pivot 8 and beneath the cutting blade. This tray has at its inner edge an inwardly projecting flange 17 formed with bayonet slots 18 which receive a headed projection 19 on the table 1. It is apparent that these slots permit the tray to be readily moved and cleaned.

From the foregoing it will be seen that there has been provided a novel guard member for rotary knives of slicing machines. This guard member cover one half of the edge of the knife and is adapted to swing about an upright axis so as to expose the knife. A guard member is also provided which is adjustable over a portion of the cutting blade to vary the size of the effective cutting portion to correspond with materials of different thicknesses. A collecting tray is employed which conforms to the cutting blade and acts as a guard for a portion thereof, thus making it possible to reduce the size of the guard to a minimum. This collecting tray is of novel form and is secured in position so that it may be readily removed for the purpose of permitting it to be cleaned.

What 1 claim as my invention and desire to secure by Letters Patent is:

1. The combination with a slicing machine having a rotary cutter, of a segmental guard member for a non-effective portion of the cutter mounted to turn about an upright axis to expose the cutter for cleaning.

2. The combination with a slicing machine having a rotary cutter, of a guard member for a non-efi'ective portion of the cutter and pivoted below the axis of turning of the cutter to turn about an upright axis to expose the cutter for cleaning.

3. In a slicing machine, the combination with a rotary cutter, of means for supporting the material to be sliced above the axis of turning of the cutter, and a collecting tray for the sliced material having a bottom wall extending downwardly from a point adjacent but below the efiective portion of the cutter and also below the plane in which the material is supported and thence under the axis of turning of the cutter.
