BERNHARD BALG in GÖRLITZ.

Addendum to patent 210159 of June 24, 1906.

Patented in the German Empire on February 9, 1907. Longest duration: June 23, 1921.

The subject of the invention is a device for carrying out the method for the production of hollow bricks, their front openings with before or after firing Clay platelets are sealed, according to patent 210159.

The method according to the main patent consists in that from one from the press escaping clay strands on the end faces with a groove provided with hollow bricks be produced, which is covered with appropriate closure plates, with the same time the side walls of the hollow stones are provided with smoke openings in a known manner will.

The subject of the invention now forms a device for cutting and simultaneous Perforating this hollow brick.

The subject of the invention is illustrated in a diagrammatic representation in the drawing.

On one end face of a cutting table are provided with suitable guide slots ζ corresponding to the shape of the end face of the hollow brick, which guide the cutting wires I ¹ , 1 ² .

The cutting wires are fastened in rotatably mounted wire holding arms, whereby between the pivot point of the arms and the cutting wires in the scenes ζ guided pins u are fastened, which when the wire holders hinged to a frame w move downward υ ¹ , ν ² , v ^s , w ⁴ den Give wires the desired direction.

In order to be able to press the ventilation openings into the side walls of the hollow brick, there are pins s which are appropriately designed to form forks.

On both sides of the device, the rods p ¹ and /> ^a are arranged, which on the one hand are firmly connected to the frame w by means of the webs k and on the other hand are guided in rings m located at the ends of the pins s. When the frame is moved up and down, the rods -p ¹ and f ² · are raised in this way, and the offset provided on the latter gives the pins s a movement in the horizontal direction corresponding to the offset.

The frame is moved up and down by hand using lever q and rods χ and r. The latter are guided in sleeves η of the cutting carriage. ^: .. ■ '

When moving the frame up and down, the pins s into the side walls

pushed in and pulled out again; at the same time when moving down the front sides of the hollow brick.

Claims (2)

Patent Claims: i. Device for carrying out the process for the production of hollow bricks, the end openings of which are closed with clay plates before or after firing, according to patent 21015 9, characterized in that the cutting of the hollow bricks is carried out by means of wire holding arms (v ¹ , t> ² , υ ³ , υ *) is effected, the balance right cutting wires fl ¹ bear 1 ² J, and in a vertically up and down movable frame (w are rotatably supported), wherein between the pivot point of these arms and the cutting wires in scenes guided pins (u) arranged that give the poor the movement they want. 2. Apparatus according to claim 1, characterized in that simultaneously with the cutting the perforation of the hollow brick with the help of cranked guide rods (P ¹ JpV is carried out, which participate in the movement of the frame (w) and thereby fixed pins (s), the ends of which are placed with rings (m) around the guide rods (p ¹ , pV , move horizontally so that when the frame (w) is moved up and down, the pins (s) are pressed into the side walls of the perforated brick and out of them again be pulled out. 1 sheet of drawings.
