The invention relates to a machine for cutting and pressing potatoes, Fruits, meat, bacon, vegetables and others used in large dining houses and the like Foodstuffs and luxury foods. For dining houses, barracks etc. are sufficient for imaginary Purposes machines with manual operation no longer, so that the invention went over to to build motor-driven machines.

ίο The new machines are working in the Hand-held machines in the usual way so that the- to be cut or to be crushed Well got into a cylinder with the bottom perforated or with knives, wires and The like. Is provided, and in which a piston is moved up and down, which the property through the opening or slots etc. in the bottom. The nature of work requires a slow downward motion of the piston ^ while on the other hand the machine it would not be advantageous for greater performances if it were carried out slowly during the same period Piston upward gear would not do any work.

The invention now has the task of creating a machine that in more uniform Way, almost continuously doing work. Those used on machines of a similar type Change gears, in which similar tasks are achieved in that the piston is long. doing work in one direction and more quickly when idling in the other direction is moved, is therefore not possible in the operation in question here, because the cylinder is filled in the upper stroke change of the working piston must be and thus the worker has to pay attention to the times of stroke change judging is necessary.

To enable automatic filling without special attention from the worker and to achieve, so that the latter need do nothing more than that to be cut up or To introduce material to be pressed, according to the invention, two cylinders and two corresponding ones Piston used in such a way that one piston goes up while the other goes down. This is how it becomes enables a switching device to be attached to the hopper, which controls the outlet of the Filling funnel always opens to the side of the cylinder whose piston is in the upper one Part of the void is located.

A machine of the new kind is on the drawing in front view, partly in Section shown.

Two cylinders b and c are attached in a suitable manner to a suitable frame α. In each of the cylinders a working piston d is arranged to be movable upwards and downwards, in such a way that, when going downwards, the material in the cylinder is pushed through the perforated cylinder

press floor e through. Each piston is attached to a rack f, which bezw in a on the shaft g. g1 attached gear engages. The shafts g, g1 are driven by gears h and /} 1 from the gears k and k1 seated on the shaft j. So that the directions of movement of the two piston rods are always opposite to each other, one of the two piston rods, here for example on the left, is arranged in a known manner to drive one of the two intermediate wheels, of which wheel k2 can be seen in addition to the ones already mentioned, while the others are behind the front ones Wheels lie. On the shaft i sit the two solid pulleys ν and r and the empty pulley I1 which are set in rotation by the two belts m and η in such a way that when the belts m and η are in the position shown in the figure, the one on the left Piston rod down, the piston rod on the right must move upwards. However, if the belts are shifted to the left by the belt fork 0, the pistons move in the opposite direction. The belt fork 0 is connected to the shafts q rotatably mounted in the frame through the intermediary of the articulated rod p. These shafts q are equipped with arms s which are freely passed through the head of the associated reversing rods t. These reversing rods t are guided vertically movably in a suitable manner in the frame so that they lie in the path of the piston d. It is readily apparent that in the described arrangement, the left piston d in its upper position must move the belts m and n to the right and the right piston d in its upper position to the left again, so that when the belts m and η are continuously driven in a suitable manner, the reversal takes place automatically in such a way that the pistons must constantly move up and down in opposite directions. A funnel u is provided between the two cylinders in two outlets u1 and Jt2, which lead to cylinders b and c. The bottom w of the funnel is rotatably mounted in such a way that, in the position shown in the figure, it must guide the material introduced into u through u1 to the cylinder b, but in the position shown by dotted lines it must guide the material through line m2 the cylinder c directs. The floor w is pivoted to rotate on two rods y by means of two arms χ. These rods 3; are appropriately ■ guided horizontally in the frame and hinged to angle lever ζ on both sides. These angle levers are fastened on a shaft 31. On this wave. z1 a short thumb 2 is also attached, which is connected to a tension spring 3 attached on the other side in the frame. The levers ζ are mounted in such a way that they are hit by the piston in the upper stroke change of the piston. It follows from this that, when the left piston ■ g, as shown in the figure, is in its upper stroke change, it has struck against the left angle lever ζ and has pressed it into the position shown. As a result, however, the hinged bottom is also brought into the specified position, so that the material in the funnel u must get into the cylinder b. If the piston then goes downwards, the rod y must follow the course of the spring 3 and bring the movable bottom of the funnel into its central position, in which the material cannot fall to either side. In the same way, shortly before the uppermost stroke change of the right piston d this will act on the right angle lever and bring the flap into the position indicated in dotted lines, so that during this time the material in the funnel must fall into the last cylinder. The operation of the machine is thus as follows: The pistons d move continuously up and down in their cylinders, namely in the downward direction, as shown on the right in the figure, up to close to the cylinder base, when moving upward, however, as on the left drawn in the figure, beyond the cylinder. This up and down movement of the pistons takes place without interruption. the reversal is done by the rods t shortly before each stroke change. Shortly before each stroke change, the material poured into the funnel is directed into the cylinder from which the piston has emerged through the intermediary of the angle lever z, against which the piston strikes during the upper stroke change. i ° 5 patent claims: 1. Machine for cutting and pressing potatoes and the like., Characterized by two pistons (d) which are moved up and down in a frame without interruption in corresponding working cylinders, to which the material is then fed in certain gaps when the pistons are out of the cylinders went out. . 2. Machine according to claim i, characterized in that the piston in its upper stroke change an automatic reversal of a reversing gear . (m, n, v, I, r) and a reversal of one in that The hopper (u) located on the hinged bottom has the effect that the material can automatically fall into the corresponding cylinder. 3. Machine according to claim 1 and 2, in which the reversal by the piston / d) and the vertical in the frame, right in the path of the piston reversing rods (t) with the mediation of angle levers (2) takes place on a with the flap . (w) articulated rod (y) act, which on the other hand is held by springs (3) in a middle position closing both filling chutes. 1 sheet of drawings.
