3 Claims; (c1.14s--102) This invention relates to slicing machines; and more particularly to the type wherein the material is manually moved along the material rest or feedway during the slicing operation.

One of the main objects of this invention is to provide a simple and readily operable slicing machine which is economically constructed so that it can be placed on the market at a minimum of cost, and will therefore find a ready sale. Another object is to provide a slicing machine whichis so constructed that the customary reciprocating material support will be entirely omitted therefrom, for the sake of economy. A further object is to arrange the various parts of .15 this machine so that the gage plate can be utilized as a guard for protecting the normally-exposed cutting portion of the knife, while the machine is at rest, and thereby cooperate with the customary knife guard and in conjunction therewith provide a complete guard for the knife. These and other objects are attained with this invention, as will appear from the following description, taken in connection with the accompanying drawings, in which:

Fig. 1 is an end elevational view of a slicing machine embodying the present invention.

Fig. 2 is a front elevational view thereof. Fig. 3 is a plan view thereof. Fig. 4 is an enlarged detail section, taken on 301line 4-4 of Fig. 1.

Fig. 5 is an enlarged detail section, taken on line 5-5 of Fig. 1, and showing how the gage plate functions as a guard for the exposed cutting portion of the knife.

comprises a base 10 provided with an upwardlyslanting standard 11 at the upper end of which the rotary slicing knife 12 is mounted, A bracket 13 is also provided on the base whereon is mounted the motor 14 for driving the knife.

A material rest or table 15 is mounted on the base in an inclined-position with the horizontal, substantially as shown in thedrawings, and it is preferably provided with depending flanges in the shape of legs 16'at its ends which are secured to the base at their lower ends, as with screws or the like. This material rest or table includes the supporting face 17 whereon the material which is to be sliced rests and is .movable therealong, as indicated by the object or material 18 in Fig. 1. An apron 19 continues from said supporting face down to the base, extending from the near edge of the knife to the near end of the machine.

' A gage plate 20 is mounted to have its operat- The form of this invention illustrated herein t guid during the Slicing Operationing surface positioned substantially at right angles to the supporting face 17, and is provided witha depending flange or apron 21 which bears upon apron l9 and is adjustably mounted thereon, as by the use of securingelements 22, like 66 bolts, which extend through slots 23 in apron 19 and have threaded engagement in apron 21, to retain the aprons together frictionally or with a yielding pressure. Index means or setting means is provided, including theouterindexed knob 2i and actuating means, as forinstance a shaft 25 and gear pinion 26 thereon for actuating arack 27 provided on apron 21 on the gage plate. 7

Ihe gage plate is with this construction arranged to be set for gaging or adjusting the thickness of slice, and is furthermore arranged so that, by the additional turning of knob 24, said gage plate can be moved in the path of the cutting edge of the knife, substantially. as indicated in the full lines in Fig- 5 of the drawings, so that it functions a guard for the normallyexposed cutting portion of the knife edge. This guarding feature of the gage plate, in addition to the usual knife guard 28 provided for the knife, as indicated in the drawings, thus furnishes a complete guard for all portions of the knife while the machine is at rest.

The guard 28 which extends on the greater part of the cutting edge of the knife is preferably made integral with a guide or guard plate 29 which is seated within the depressed portion or cut-out portion 30 provided in the knife, whereby the material is guided along the inner side of The material is engaged by the hands and moved along the adjacent faces on the material rest and on the gage plate, which are positioned substantially perpendicular to each other and form the feedway which is substantially V-shaped in cross-section, or is trough-shaped, preferably extending parallel to the base of the machine, and along which the material engaged by the hand is then readily moved during the slicing operation; thus providing a simple and inexpensive mechanism and producing an economical machine on which the material is readily sliced. These adjacent faces of the material rest and the gage plate, as well as the exposed face of the guide A scraper 31 is preferably secured to the lower portion of the knife guard 28, to keep the cutting edge of the knife clean from material, as best indicated in Fig. 4. It has its scraping edge extending substantially vertically, to more readily deflect downwardly or drop the particles of inaterial scraped from the knife.

The material rest or table has its lower portion fitting closely to the guide plate at the inward side of the knife, and also closely to the peripheral edge of the knife, so as to firmly support or hold up the meat or material in its proper position until it is completely sliced, and this arrangement thus avoids any frayed or ragged cutting of the material.

I claim:

1. In a slicing machine, a horizontal base and a knife mounted rotatablythereon, a material rest mounted inclined and stationary upon said base, a driving motor for said knife mounted on said base beneath said rest, a gage plate having its operating face positioned at an inclination with the co-operating face of the material rest, thereby providing a trough-shaped feedway extending generally parallel to the base and the knife edge and whereover the material is slid to and fro by hand, and means for adjusting the gage plate for the desired thickness of slice and also for moving said plate in the plane of the knife edgeto function as a complete and fully effective guard for the normally-exposed portion of the cutting edge of the knife.

2. In a slicing machine, a horizontal base and a circular slicing knife mounted rotatably therei on, a material rest having flange means in the form of supporting legs depending from its upper part for mounting it stationary and at an inclination upon said base, said rest including an upper guide portion and a lower supporting porition, a gage plate having an upper guide portion co-operating with the guide portion on said rest for providing a smooth trough-shaped feedway which has its lower edge substantially parallel to the base and to the knife edge and whereover the material is slid manually, means on the lower portion of said gage plate seated on said supporting portion on the rest, and means for adjusting the gage plate and its lower means along said supporting portion on the rest for regulating the thickness of slice and also for moving the gage plate in front of the normally-exposed cutting portion of the knife edge to function as an effective guard therefor.

3. In a slicing machine, a horizontal base and a rotary circular knife mounted thereon to have its cutting edge inclined thereto, a material rest having flange means depending from its upper part to the base for mounting the rest stationary and inclined thereon, said rest including an upper guide portion and a lower supporting portion, a gage plate having an upper guide portion extending substantially perpendicular to the guide portion on said rest and therewith providing a smooth trough-shaped stationary feedway which has its lower edge substantially parallel to the base and to t e knife edge and whereover the material is moved manually to and fro of the knife, flange means on the lower portion of the gage plate seated on the supporting portion of the rest, guard means including outer curved means for guardin the major portion of the knife edge also inner plate means integral therewith and positioned within the confines of the knife edge to co-operate with the gage plate for guiding material along the knife, and means for adjusting said gage plate and its lower flange means upon said supporting portion for regulating the thickness of slice and also to move the gage plate in front of the normally-exposed cutting portion of the knife edge and within the plane thereof to function as a guard and in conjunction with said curved guard means to protect the entire knife edge. 1
