CARL HEILINGER AND MATHIAS LISATZ, OF LOS ANGELES, CALIFORNIA; SAID LISATZ ASSIGNOR T0 SAID HEILINGER.

VEGETABLE-CTTING' MACHINE.

Specification of Letters Patent.

Patented J an. M, 1916.

To all whom it may concern Be it known that we, CARL HEILINGER and MATHIAs LIsA'rz, both citizens of the United States, residing at Los Angeles, in the county of Los Angeles, State of California, have invented new and useful Improvements in Vegetable-Cutting Machines, of which the following is a specification.

This invention relates to a vegetable cutting machine.

It is the object of this invention to provide a machine for slicing vegetables which is particularly adapted for use in slicing potatoes in the manufacture of potato chips, and which is so constructed that the potato may be formed into latticed slices.

Another object is to providea machine of the above character which is rapid in its operation and which will slice the potato with comparatively little waste.

A further object is to provide means whereby the latticed slice will be readily ejected from the machine to prevent clogging of the latter, and also prevent breaking of the latticed slice.

The invention is illustrated in the accompanying drawings, in which:

Figure 1 is an inverted plan view of the machine, with parts broken away. Fig. 2 is a view in side elevation of the machine in its upright position, as seen vin the direction indicated by the arrow 2 in Fig. 1. Fig. 3 is an enlarged detail vertical section and elevation on the line 3-3 of Fig. 2, as seen in the direction indicated by the arrows. Fig. 4 is an enlarged detail section and elevation 'on the line 4-4 of Fig. 2, as seen in the direction indicated by the arrows. Fig. 5 is a detail in perspective illustrating a portion of a latticed potato slice as formed by the machine. Fig. 6 is a view of same in section, as seen on the line 6 6 of Fig. 5.

More specifically, 10 indicates a table top or panel forming the dais or support of the machine, which is arranged on the under side thereof. Mounted on the under side of the panel 10 are 'a pair of rails 11 and 12 of approximately corresponding lengths formed with longitudinally extending channels 13 on their adjacent faces; a complementary pair of rails 14 and 15, having longitudinal channels 16 on their adjacent faces being arranged at right angles to the rails 11 and 12 with the rail 14 connectingv with the rail 12 by a mitered joint 17, as particularly shown in Fig. 1.

Disposed between the rails 11 and 12 is a reciprocal frame 18, which is formed with longitudinally extending; ribs 19, which slidably engage the channels 13, and disposed between the rails 14 and 15 is a complementary frame 20, having longitudinally extending ribs 21 on its opposite sides slidably engaging the channels 16. The frames 18 and 20 are adapted to be reciprocated simultaneously in opposite directions in relation to the angle of intersection of the rails.

For the purpose of operating the frames 18 and 20 simultaneously, they are connected together by means of a bell-crank lever 22, pivoted at 23 on the under side of the panel 10, and attached at their ends to the frames 18 and 20, by means of pins 24 and 25, carried by the frames '18 and 20 and extending through slots 26 and 27 formed in the bell crank lever 22, and the frame 18 is connected to a pitman rod 28, disposed in a slot 29, formed in the panel 10 and connected at its outer end to a crank 30, on a shaft 31, adapted to be rotated continuously.

Mounted on the frame 18 is a blade 32, which is formed with a series of corresponding right-angle corrugations extending longitudinally thereof and terminating at the forward end of the frame 18 in a cutting edge conforming to the end walls of the corrugations. The blade 32 is thus formed with a series of longitudinally extending channels 33 on its outer face which alternate with corresponding channels 34 on its upper face; vertical walls 35 separating the channels 33 and 34 and horizontal walls 36 and 37 forming the bottom Walls of the channels 33 and 34 respectively, connecting the edges of the walls 35, as particularly shown in Fig. 4.

A blade 38 corresponding with the blade 32 is mounted on the frame 20 and disposed on a plane lower than the plane of the blade 32 with the upper walls 36 of the channels 33 extending on the plane of the lower Walls 37 on the blade 32, as illustrated in Fig. 3.

Formed on the panel 10 concentric with the inner section of the point of intersection of a line extending midway between the rails 11 and 12 and a line extending mid way between the rails 14 and 15, is a circular opening 39 through which the potato or other' vegetable to bev sliced is introduced through the panel 10 from its upper side to extend in the path of travel of the blades 32 and 38. As a means for limiting the eX- tent of projectionof the vegetable through the opening 39 a pair of stop-plates 40 and 41 are mounted on the adjacent ends of the frames 18 and 20. The stop-plate 41 is formed in continuation of the lower Wall 37 of the channels 34 of the blade 38 and the stop plate 40 extends-on a plane with the stop plate 41, being carried on dependent brackets 42 formed on the end of the frame 18.'- The stop plates 40 and 41 are triangular in form, with their inclined edges arranged to slidably contact each other as the frames 18 and 2O are reciprocated.

As a means for engaging the vegetable on the side thereof opposite the cutting edge of the blades 32 or 38 and to form an abutment against which the edge of the blade strikes after passing through the vegetable, a pair of vertically disposed abutment plates 43 and 44 are provided. The plate 43 ismounted on av sildable bracket 45 formed with guide slots 46 engaging studs 47 projecting from the under side of the panel 10. The bracket 45 is connected by a pin 48 to the end of aV lever 49 pivoted at 50 to the panel 10, the outer end of which is curved to form an arcuate face l51 adapted to be engaged by a pin 52`on the frame 18 and by means of which thelever 49 rocks on retracted movement of the frame 18 to advance the abutment plate 43 into a position to engage the vegetable. The abutment plate 44 is likewise mounted on a slidable bracket 53 connected to a lever 54 pivoted at 55 on the panel 10, and having a curved end 56 adapted to be Aengaged .by a pin 57 on the frame 20 as the latter is retracted.

lA vegetable is inserted in the aperture 39 resting upon the cutting blade 32, the blades being inthe position shown in Fig. 1. As shaft 31 is rotated the crank 30 moves the connecting rod 28 to the left and with it the blade 32. In the latter part of its movement the vegetable rests upon the plate 40. Blade 38. advances simultaneously by reason ofbell-crank lever 22 pushing it forward. The plate 41 follows plate 40, and the vegetable is retained in the same plane resting upon plate 41. The pin on frame 19 engages the curved end 51 of the lever 49 moving the abutment bracket 45 forward and after the cutting blade 38 reaches the vegetable it makes a corrugated cut, the abutment plate 43 holding the vegetable from sliding.

Upon continued rotation of the shaft 31 the crank y30, connecting rod 28 and' bell-crank 22 causes the cutting blade 32 to .be moved forward and cutting blade 38 to be retracted. The vegetable rests upon plate 41 until plate 40 moves underneath it, then the cutting blade 32 makes a corrugated cut of the arm. A slice is completed and drops into a receptacle below the aperture 39; the slice made is of a form shown in Fig. 5. Upon further rotation of shaft 31 cutting blade 38 makes a cut completing a slice. It will be noted'that plates 40 and 41 hold the vegetablein proper position for making the slicing cuts, no auxiliary mechanism other than this being required.
