F. Beavers, Belen, N. Mex. 7 Application F ebr'uary 17, 1950, Serial No. 144 777 4 Claims. (Cl. 146-168) This invention relates to a slicingmachine particularlyadapted for the slicing of potatoes "and like foods in attractive shapes, .but usable :also for ordinary or plain slicing as well. 1' a One important object of the invention "is .to' provide a slicing machine f the type' fstated adapted toslice potatoes and similar foods :into 'waffle-likeslices." I 1,

" A-nother'important objeet is to provide a slicing -machine of the type stated that will-perform fancy slicing operations 'with" speed and ease;

Still another obj ect is to provide a slicing machine that can be manufactured at relatively low "cost but which Will be quite efficient and durable. Still another'object'is-to provide a slicing machine which, thoughlcapab'le of "manufacture at no greater cost than conventional slicers never- "theless can be used' for allthe plainslicing functions discharged by a conventionally constructed slicer, aswell as theslic'ingo'f or ornamental shapes.

'With the foregoing and other objects in :view "whichfwill appear asthe description proceeds,

the invention consists 'of1certa'in novel details :of

f construction and combinations of part r-hereinafter-more fully describedand-pointed out in the-claims, it being understood that changes may be made inthe construction andiarrangementof parts without departing 'from the spirit of-the invention as claimed. 5 5

Referring to the drawing in detail, I provide a fiat base I which is-here shown asasubstantially rectangular, heavy plate of metal material, although the plate can be ofother shapes or materials, the base I being formed at its ends with the 'rearwardly extended wings 2 in which are threaded the screws 3 that fixedly connect to said wings 2 the opposite ends of an elongated guide rail 4 here shown as rectangular in.

The oppositeends'of the tubular carriage I may of course be provided withrubber bumpers or the like for the usualiwell kn'own'purpose,

and this has "been considered suffieientlycbvious as not'to require special illustration.

'From what has been so far described; it will be seen that upon the rear portion of thebase :l I provide a slideway upon which is mounted for slidable reciprocating movement a supporting carriage. that is held against .wobbling during its travel by a suitable guide means. In this connection, although I have illustrated the'carriage as being reciprocable manually, I' believe it is quite possible to give reciprocatin'gtmovement to'saidcarriage from end toend of its-elong'ated-slideway by'any of various well known power operated devices, not shown..

Mounted rigidly upon the top of the carriage 1, and extending laterally and horizontally therefrom, is'a T-shaped bearing'plate I'2-, upon which are rigidly mounted the bearing sleeves :13, aligned crosswise-of the slide rail-l0, as readily seen from Figs. 3 or 6. Extending through the "bearings 13 is a rock shaft "I 4 to the opposite ends of which are .fixedly secured .the short sup- Fporting arms 15 each of which has at its upper *end an'angular recess [6. receiving the angular corner portion at each'end .ofa foodcarrier l1 L-shaped in cross section, said carrier J1 being rigidly connected to the vrespective supporting armslfi.

The outer end of theioodcarrier Il is provided with the end wall l m-while slidably mounted in the-inner end of said carrier is the presser foot I9 adapted to pressa potato or other article of food to be sliced forwardly against a cutting made :apparent hereinafter. z

The presser foot 19 is secured to .oneend of a follower rod 20 around-which is positioned the 3 compression spring 2| one end of which abuts against the presser foot 19, the other end of said spring abutting against the sleeve 22 interposed between the spring and end wall 18, a take-up nut 23 being threaded upon the rearwardly projected end of the follower rod 20, for the purpose of adjusting the spring tension.

Secured to the corner portion of the carrier ll at the inner end of said carrier and extending downwardly from said carrier and obliquely to the carrier walls is a dog 24 that is rigid with the carrier, and which is formed in the present instance as a short bar the free lower end of which is formed with the angular'end surfaces.

25, either of which is slidable along a bumper rail 26 extending parallel to the slide rail I and rigidly mounted upon and above the base "I- by means of supports 21.

upon the angle member 4| that is secured in any suitable manner to the base I.

The cutter 34 in the present instance is formed as a rectangular plate having the transverse corrugations, the opposite edges of said plate being sharpened so as to cause slicing of the article of food upon travel of the carrier in both directions.

The form of cutter illustrated, in this connection, is a form particularly adapted for the slicing of potatoes or similar articles of food in waffle-like shapes. However. various forms of 1 cutting knives .34 can be detachably secured to the upstanding-arm 35, and these forms can be,

for example, plain cutter knives, cutter knives having closely spaced corrugations for julienne potatoes; cutter knives having waved cutting The bumper rail 26 is shorter than the slide rail H3, terminating at both ends well short of the adjacent end of .the slide rail 10, asbest seenfrom Figs; 1 and 2; "From what'has been-described it maybe observed that the food carrier is mounted for rocking .oroscillative movement .uponthe sliding carriage. During travel of 1 the slidingcarriage .in cne" directionyone wall-26i of the foodcarrier willTbe-horizontally positioned, while the outer wall is vertically positioned. The carrier will be held against movement from this position because the dog 24, during said: slidable travel of the carrier in one direction, is in engagement with the bumper ;rail 26. Rocking movement of thefood' carrier in an opposite direction is limited bymeans of either one of a pair of adjusting screwsv 29- threaded in the plate l2.,and limiting oscillating movement of the food the food carrier is instantaneously rocked to its other'extreme position, with the wall 25 of the -foodxcarrier now being horizontal and, the wall 26 being verticaLthe carrier thus'in efiect be- -ing rocked. through ninety degrees from one extreme position to. another, and beinggiven this .movement'each time the carriage reaches the limit of its slidable travel past the'cutting'means of the machine, and begins itsreturn travel.

' Thesupports 21 for the bumper rail 26 are rigidly attachedinlany suitable manner to the basal, as for example by screws 28.

Rigidly mounted by'mean's-of supporting arms 30 in elevated position above the base i is a fiat table 3| along one side of which is mounted the elongated vertically positioned sidewall 32, be-

tween the ends of which is formed the space 33 'inwhich is"a'djustab1y mounted the vertically positioned cutter plate 34 detachably and fixedis connected to the upstanding arm'. 35, rigid at its lower end with the horizontally extending foot 31 sliding in the guide 38 mounted upon the base I. A clearance space 36 for said upstanding arm is fornied in the table 3!, to permit room for adjustment of the supporting arm. Such adjustment is achieved in the present instance by means of the advancing screw 39 formed at one end with a knurled head or the like, and swiveled at its other end in the cutter support 35, said advancing screw 39 being threadedin the upstanding bracket 40 mounted edges, etc.

Inuse, the advancing screw 39 is operated so as to provide the desired space between the cutter 34 and the stop wall .32. Obviously, the greater this space, the thicker will be the slice.

In any event, thepotato P is positioned as illustrated, and the user simply gives reciprocating travelto the'carrier I to its opposite extreme positions, as a result of which the potatoes will be cutto wa'file like shapes or slices. On movement of the carrier in one direction, with the side wall 26' positionedhorizontally, a slice having a corrugated surface will be cut from the potato P. .When the carrier reaches the end of movement in'one'direction, the food carrier will be rocked to its other :extreme position, turning the potato P ninety degrees. As a'result, when the potato moves back pastthe cutter, a slice will now be cut off one surface of which is corrugated at right angles to the other surface. If the slice is cut oil so as to be quite thin; a wafilelike, attractive shape will be given the slice, and if the slice is thin enough, the slice will be formed with a grid-like arrangement of openings extending fullytherethrough. These slices may then be readily French fried and provide anattractive way. ofserving the potatoes or other articles'of food out... the carriage I continues its reciprocating movement back and forth past the cutter, continued slicing of the, potato results; with each slice having its corrugations on one face'at right angles to the corrugations on the opposite face. I i

If it is desired that ordinary slicing operations be carried out, it is necessary only to replace the cutter 34 with a plan cutter, that is wholly flat, and this will cause the slices tobe wholly conventional, thus to-permit the slicer to be used for slicing luncheon meats or the like.

What is claimed is:

1. A slicing machine including a base; a carriage slidably reciprocable thereon; a cutter stationarily mounted 'on'the' base and disposed intermediate opposite extreme positions between which the carriage is shiftable; a food carrier rockablymounted on the carriage; a bumper .rail rigid with the base and paralleling the line of reciprocating movement of the carriage, said rail terminating at opposite ends short of the extreme positions between which the carriage is reciprocable; and a dog rigid with the carrier, said dog being shiftable gravitationaly into'the path of the bumper rail and being normally held against said shift by the bumper rail, said dog gravitating into the path of the respective. ends of the bumper rail upon shifting of the carriage to its respective extreme positions, for engagement of the dog by the bumper rail to rock the food carrier at the beginning of return movement of the carriage toward the cutter.

2. A slicing machine including a base; a carriage slidably reciprocable thereon; a cutter stationa'rily mounted on the base and disposed between opposite extreme positions to which the carriage" is shiftable; a food carrier mounted on the carriage to rock in a vertical plane; stops on the carriage limiting rockable movement of the carrier through approximately 90 in either direction; a bumper rail rigid with the base and paralleling the line of reciprocation of the carriage, said rail terminating at opposite ends short of the extreme positions between which the carriage is reciprocable; and a dog rigid with the carrier and swingable in a vertical plane, said dog sliding upon and being elevated against gravitational swinging movement by the bumper rail during shifting of the carriage past the cutter in either direction, said dog sliding off opposite ends of the bumper rail on movement of the carriage to its respective extreme positions and shifting gravitationally into the path of the bumper rail, for engagement by the ends of the bumper rail to rock the carrier from one of its extreme positions to the other at the beginning of return movement of the carriage.
