wandering filling form.

Patented in the German Empire on February 20, 1912.

The automatic drop ram presses for the production of masonry stones, which for larger ones Benefits are determined, almost all suffer more or less from the fact that the filling of the molds is uneven and thereby the compacts are unevenly high and crooked. In the case of the falling weight presses that have become known with the filling box moving back and forth, the latter is overlaid with its open bottom

ίο a fixed floor to the press box pulled, whereby the pressed material in the filling box due to the friction over the solid The floor is compressed towards the back wall, whereas it becomes loose in the front of the box. As soon as the filling box over the If the press box arrives, the loose material to be pressed in the front of the filling box falls down immediately and the firmer, at the back of the hopper lying on top, so that the pressed material in the press box forms an inclined plane, with the result that the compacts are uneven Preserve pressure and get crooked.

This Ubelstand is to be eliminated according to the invention that the filling box rests on a table top mounted on rollers, which when the filling box is pushed forward by the weight and the adhesion of the pressed material located in the filling box up to is taken over the press box and then quickly withdrawn. When withdrawing of the table, the filling box is directly above the press box, whereby the entire filling is in the press box at the same time falls and fills it evenly!

In the drawing, the press forming the subject of the invention is shown in FIG

Fig. Ι in a front view, in

Fig. 2 in a plan view, in

Fig. 3 in a side view and in '

Fig. 4 is also shown in a side view, but with individual parts in section.

The operation of the machine is as follows:

The pressed material falls from the mixer directly into the storage box a, b passes therefrom into the underlying hopper, which is loosely on a movable table top rests c. The latter also forms the bottom of the filling box b. The filling box is pushed forward by means of an eccentric d to over the press box e , the table top c through. the weight of the goods in the filling box is taken along. As soon as the filling box has reached its extreme position over the press box, the table top is pushed back by the roller f, which is attached to the eccentric g, whereby the filling box is opened at the bottom, so that the now falling ram h pushes the material through the filling box conveyed into the press box. There are now in a known manner two strokes of the punch h in quick succession, then the filling box is pushed back under the storage box to get new material to be pressed

take up, the ram falls down again in the meantime and remains on the compacts until the press box is lifted over the compacts by means of the two eccentrics i. Now the ram is raised by means of the eccentric g , whereby the support board with the compacts is free and by means of two endless chains k forward on the lifting table or

ίο any conveyor device is pushed. At the same time a new board is placed under the press box on the press stick /, on it goes, the press box except for ^: the board down, and the filling box comes forward again as before.

Claims (1)

Patent claim:
Automatic plunger press for the production of bricks from cement, slag and the like. With a filling mold moving back and forth under a storage container, characterized in that the filling box (b ) rests on a table top (c) mounted on rollers, which when the filling box is pushed forward by the weight and the adhesion of the material to be pressed inside it up to the press box, but then immediately pushed back into the starting position by a roller (f) seated on the eccentric (g). 1 sheet of drawings.
