Patented in the German Empire on June 4, 1896.

The present invention is used in pressing with uniform and simultaneous Knee lever pressure from above and below on the dry fruit in the molds a quick one Sought to achieve movement of the upper punch, regardless of the movement of the Knee-lever prefabrication for quick removal of the stones and quick refilling of the To enable preforms. For this purpose, the upper punch slide is essentially made in three parts, so that two parts of it, the upper die and one between it and part built into the upper part of the guide carriage, each received a particular movement can. A specially arranged eccentric and lever mechanism is used for this purpose, the timely quick elimination of the intermediate piece in question within the upper punch carriage concerned. The other activities of the machine, such as filling, pressing and ejecting the brick, are carried out in a known manner and with known means.

The press is shown in the accompanying drawing.

The drive takes place from the pulley A by a gear drive BCDE, which ' sets the crankshaft F in rotation; a connecting rod G sets the handle H in a the like in the frame bearing axis H ^'2 rotating, up and down continuous vibration which it transmits the toggle lever-like connected thereto by bolts J ² K ² levers J and K. These levers are respectively by bolts L. M is connected on the one hand to a vertically movable crosspiece N and on the other hand to the upper punch slide Ai ¹ . The lifting and lowering of the crosspiece N is done in a known manner and is transmitted to the crosshead P by means of the bolts O (see patent no. 55580). The bolt M of the lower toggle lever presses down the upper punch slide M ¹ in its guides between the frame a at the same time and to the same extent as the bolt L of the upper toggle lever lifts, whereby the upper press punch R attached below it is pressed into the price form, in that an intermediate piece V is switched on between the Siempelträgerblock A ¹ , which can be displaced in the slide M ^1, and the upper part of Ai ¹ and remains held at the Prefs lowergang.

In order to be able to bring about a quick lifting of the block A ¹ carrying the upper press ram after the pressing has taken place , the intermediate piece V is disengaged into the punctured through. Lines indicated location. In addition

Claims (1)

At the end of the crank axis F is a non-circular disc T on which a roller U rests at the rear end of a two-armed lever U ^1; the other arm of this oscillating lever about the axis U ² U ³ conceives a pull rod, which the intermediate piece V is in turn connected to a lever arm V ^1, resulting in timely, zwangläufige activity of his intermediate piece V it follows. The rapid lifting of the block A ¹ is effected after switching off V, as follows: Between the uprights a an axis X ^{1 is} mounted close to the floor; on this one sits on the left and right a respectively. two-armed lever XYY ¹ ; at the free end of X is a roller x, on which a non-circular disk W acts at the right moment and X down or. YY ¹ pushes up. Since the front ends of Y and Y ¹ engage in pockets or openings of the rods Z on which the block A ¹ is supported and held, the rapid lifting of this piece can be carried out independently of the lifting of the carriage M in this way. The rapidly rising upper punch support block A ^{1 is} followed in the same step by the lower crosshead P. A two-armed lever d is freely rotatable about the axis X ¹ , at the inner end of which ^{sits a roller d 1} , on which a non-circular disk b acts, while the The end of the front arm of d engages in a pocket in the crosshead P by means of a roller d ' ² and thus brings it to raise and lower it. As soon as the lower press ram is raised so high that the stone is exposed, it is ejected by the forwards moving filling mold h , while this at the same time fills new material into the already retracted mold. The filling form is actuated by means of the track disk g and the lever i and the rod k which are in engagement with it, as can easily be seen from the drawing; As soon as the filling box is withdrawn after the preform has been filled, the disk T acts again on the lever mechanism U ¹ U ² C / ³ and the intermediate piece V, so that this is again forced to assume its vertical position, whereupon the connecting rod then arrived in the lowest crank position G acts on lever H and the toggle pressure takes place, which causes the actual pre-compression pressure to act simultaneously and equally on the two punches R and Q. Pa τ ε ν τ - A ν s ρ R υ c η: A drying press, in which pressure is exerted simultaneously from above and below through the two press punches on the molded piece, characterized by a 'arranged in the upper stamp slide (M ¹ )' under the action of a non-round disc (T) and a lever mechanism (UU ¹ U ^B V ¹ ) standing intermediate piece (V) which, depending on the position and activity of the upper punch, can inevitably be adjusted so that the punch support block (A ¹ ) inserted in the lower part of the slide (M ¹ ) is independent of its movement Movement permitted, or else all three parts, carriage, intermediate piece and punch support block, combined into a rigid whole, the independent movement of the punch support block being effected by the fact that it is supported by rods (Z) and connected to them, which are in the lower crosshead (P) and are raised and lowered by an eccentric (W) and roller lever (x XYY ¹ ).
