VEGETABLE-CUTTER.

SPECIFICATION forming part of Letters Patent No. 537,831, dated April 23, 1 895.

Application filed December 12, 1 894. Serial No. 531,537. (No model.)

To whom it may concern;

Be it known that 1, LEE JOSEPH KRAEMER, a citizen of the United States of America, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Vegetable- Cutters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in machines for cutting into pieces vegetables and fruits, and particularly to machines for cutting up potatoes.

The objects of my machine are, first, to pro vide a machine that will cut potatoes into the numerous dilferent sizes and shapes in which they are at the present time prepared for the table; second, to provide a vegetable cutter which can be quickly adjusted to cut vegetables and fruits into even slices, strips or other forms; third, to provide a simple'and cheap manually operating vegetable cutter of large capacity. I attain these objects by the mechanism illustrated and described in the accompanying drawings and specification, in which-- Figure 1 represents a perspective view of my improvedvegetable cutter. Fig. 2 represents a longitudinal sectional elevation of the same. Fig. 3 represents an end elevation of the same. Fig. at represents a fragment in perspective. I

Similar letters and figures of reference refer to similar parts throughout the several views.

Referring to Fig. 1, A and B represent the sides of the machine which is preferably constructed mostly of hard wood, and O a horizontal partition or table which is secured between the sides at one end by the bolt 0 which passes transversely through the table and sides and binds them all together, and also bythe screws 0 The inner edge of the said table is preferably cut at an oblique angle with the sides. A knife-plate D fits the space between the said sides at the opposite end and is adjustable vertically between them independent of the table O. Theinner edge of this plate is also out obliquely to correspond to the oblique edge of the table 0 and it is arranged so that a space intervenes between them.

The plate is provided at its outer edge with a blade of metal E which is attached to it. This blade projects on either side of the plate and fits into the slots F, a number of which are cut into the sides. The plate can be raised or lowered in relation to the stationary table by moving it from one slot to another. On the inner oblique end of said plate I securea cutting knife Gr, arranging it to extend close to the edge of the table 0. This knifeis also set parallel with the oblique edge of the table and plate, which gives the article to be cut a shearing movement against its edge as it is reciprocated in the machine.

Intermediate of the knife and the Outer end of the plate E, I place transversely through it and the sides a rod H, which is threaded at both ends. I use thumb-nuts H on the threaded ends, as these admit of manipulation with-- out a wrench. The hole I, in the plate, th rough which the threaded rod passes is elongated laterally in order to enable the plate to be moved back on it far enough to disengage the blade from the slots F without removing the rod. The threaded rod passes through vertical slots J, made in the side of the machine. Metal washers K are set into the sides to receive the pressure of the thumb-nuts and protect the wood. The. slots J enable the plate and threaded rod to be raised or lowered vertically between the sides by loosening the thumb-nuts. Thetable O is provided at its inner edge with a plurality of-slots L spaced a short distance apart, through each of which extends vertically a knife M. These knives are pivoted to a pin N'which passes through them and through a plate 0, which is also provided with slots in line with those in the table 0. The knives are pivoted in the slots of the plate.

A cross-bar P extends across the backs of the knives from the sides A and B and forms an abutment for them to bear against, which prevents their being carried against the edge of the knife G by a vegetable being drawnf through them. This crossbar P rests in re adj usted vertically independent of the oppo cesses Q formed in the bottoms of the sides, as shown in Fig. 4, which is a bottom view of a fragment of the machine. This view shows but one side B, but both sides are provided With recesses. The edge of the table is rabbeted to allow the cross-bar to extend .under its edge to the knives.

In Fig. 4 the cross-bar, and the knife G and adjacent parts are represented as arranged-at right angles to the side B, but they are preferably arranged obliquely as in Fig. 1. The cross-bar P is held in place by two pins B, one I in each side, the lower ends of which are bent at right angles and are adapted to bear on it with resilient action.

The plate 0 is adjustably-supported adjacent to the vertical knives'lll to the table '0 by a bolt S. 'Thisbolt passes downthrough the table and plate. Its threaded end :is .provided with a thumb-nut T. By means of this bolt and nut the vertical knives are raised or lowered through the tableO and are thereby adjusted for cutting depth. The oppositeend is removabl-y pivoted to a row of holes formed on the inside face of the sides by springs V. These springs are preferably formed of round spring wire. Piecesof wire of sufficient. length to secure-agood spring-are seated in grooves 'V' out in thesideedges of the plate. The inner end of thewire-isbent at right angles and extends into the plate. The outer end extends beyond the machine? and is curved downward and returned to the sides, forming a loop, and thisend is bent out-f ward at right angles and extends into .the holes U. By .pressing'the ends of the springs, together and disengaging the ends from thei holes they are in, thisend of the plate-maybe;

site end.

The inner faces of thes-ides A and Babovei the table 0 are provided with a number .oifl grooves W, which extend throughout their length. These grooves are adapted tosup-I port reciprocatively a carriage X. Thisca-r riage consists of a square box-orihopper made preferably of galvanized iron or ti-n. Its upper edges and-lower end edges are rolledlover. I'ts lower side edges are turned outwardat right angles, thereby forming lips Y which extend into oneof the grooves vononesid-eand into the opposite parallel groove of the other side. By the use of several grooves the carriage can be moved from one to'another, and can be placed close to the knives or at a distance above them, depending on the size of the Vegetables to be cut.

The operation is as follows: The vegetables or fruits to be cut up are placed in the carriage as shownin Fig. 2. The carriage is then reciprocated in the grooves by handover the knives. The hand is held so as to press and hold the articles down against the table and knives. The vertical knives M cut the articles into strips, while the knife G cuts them into slices. The vertical knives are spaced about one eighth inch apart, and if it is desired to cut potatoes into what are called shoestrings, that is, into strips about an eighth of an inch square, the horizontal knife G should be set and secured by the thumb-nuts H at that distance above the table 0. Then if the potato is moved over the knives by the carriage it will'be cut into strips one eighth inch square. These strips can also be made one quarter inch square by setting the horizontal knife atthis height above the table 0 and by dropping out every other one of the vertical knives which can be done by taking out the cross-bar Pand swinging them down in the direction of the arrow 1 in Fig. 2. The remaining knives should then be raised one quarter inch above the table 0. By various adjustments potatoes can be cut a number of varying t-hicknessesand \vidths, such as one half or threeeighths i nches,'or five eighths or three quarters inches square, or one eighth byone half inch,one quarter by one half inch, onehal'fby three quarters, the. By dropping all of the vertical knives below the table O,'

\vholeslices of any thickness can :be out. By dropping out one halfof the knives in the widthof the machine and leaving the balance abou-tone eight-h inch above thetable and the horizontal knife at the same height, if a potato is then moved into the knives about one half through it, and then moved back andre-- versed end for end, and- :moved again into the knives, b'utnot quiteha'lfthrough it'and again moved back and then moved to the other side from which the knives have been removed and then passed over the horizontal knife, the'sliee -.will t'hen be cut clear and the slice obtained will have string ends and a solid cont-er. WVhen this is fried the ends will curl invarious.directions,-producing a style much used by caterers to decorate dishes.

With this machine a much larger amount of work: can be done than by hand, and it wlil also do the work much better than it can be done by hand. Apples,cueumbers and pickles can be sliced with it, and carrots, parsnips, pickles and similar shaped articles can be cut into strips.

In the bottom .of the corners of the sides I secure in a convenient manner, sharp points 2, which are adapted to be pressed into the top of a tableor board for the purpose of preventing the machine from slipping about while being used.

Having described my invention, what I .claim as new, and'desire to secure by Letters.

Patent, is

1. In a vegetable cutter the combination with the sides and table of a horizontal slicing knife adj ustabl y secured adjacent to the table in the path of the vegetables, a plate piv- .oztallyand adjustably secured to said sides at .one end below said table by springs embedded in slots formed on its side edges and extending beyond the side for a finger catch .and formed and adapted to resiliently enter a ver= tical row of holes formed in said sides whereby this end of said plate may be raised and low IIO ered in relation to said table, a row of slots Spaced an even distance apart in the opposite end of said plate, knives of suitable form pivoted in said slots and extending up through similar slots in the edge of said table, a rabbet formed in the edge of said table, a crossbar detachably secured in said sides and fitting said rabbeted edge of the table adapted to hold said vertical knives in said slots and from contact with said horizontal knife, and means substantially as herein described for adjusting said vertical knives for cutting depth, as herein set forth.
