MARTIN PRAEKELT and KARL RAHN in BUNZLAU (Silesia). Machine for pressing roof tiles.

Patented in the German Empire on March 28, 1880.

The patent relates to devices on extrusion presses for the production of beaver tails, consisting in the slide S, which enables the formation of the nose, the cutting knife M and in roller tables which, when folded, cut the clay strand with a knife attached to it and then the cut brick Drop the ready-made storage boards.

Fig. Ι is a view of the mouthpiece of the machine;

. 2 shows a longitudinal section of the cutting and lifting device;

Fig. 3 is a top view of the left half of the same;

Fig. 4 shows the attachment of the slide to plate a, and

5 shows the knife which cuts one side of the roof tiles round.

The machine consists of a rolling mill which presses the clay into the price box K. In this price box K a punch moves back and forth, which prefst the clay from the price box K through the two mouthpiece openings ο onto the double roller table of the cutting device .

The slide 6 ¹ moves in front of the mouthpiece plate α screwed to the price box K. On the slide> S there are two flat pieces s ¹ and s ² leading in the flat slots of the mouthpiece α , which are held by counter-plate and drag springs and thus form an elastic guide. The slide £ is mounted on the mouthpiece plate by means of the guide pieces s ¹ and s ^{2 in} such a way that in the lowest position the edge cd, Fig. 1, of the slide S ends with the uppermost edges of the openings 0 in the mouthpiece. In addition, the openings for the noses to be pressed are incorporated at the relevant points of the slide S. These openings are covered by a screwed flat rail f on the slide S.

A cast iron frame R ^{x is} placed in front of the mouthpiece plate α of the Dachstein press, on which a frame R and R is rotatably arranged by means of the cast lugs and screwed-in studs r and r ^1, corresponding to the two openings ο. The frames R and R carry the guide rollers.

A doctor blade m is screwed onto the transverse rib g ^{1 of} the frame R, which is located just in front of the mouthpiece plate α.

A knife or wire, particularly drawn in FIG. 5, is attached to the columns A by means of clamping pieces g ^x and g ^2. The columns A and the slide S are both connected to the lever ν attached to the shaft w , so that both are moved simultaneously by guiding w by means of the crank w ¹ .

The mode of operation and handling of the machine is as follows:

The clay brought into the filling box f is pressed into the box K by the rolling mill. The slide 5 is in the lowest position, as shown in FIG. After the box K is filled with clay, a punch working in the box K comes into effect and presses the clay through the mouthpiece opening 0 onto the roller table R. The plate screwed onto the slide that only one flat strand of clay comes out of the mouthpiece. After the punch finishes its forward speed and now goes back, i.e. the pressure ceases, the slide S is moved upwards and the cutting device A downwards by rotating the shaft w. This cutting device A with the clamped wire or knife M gives the roof tile the desired rounded shape.

Underneath the slide S there is now enough space to cut the string of clay right in front of the mouthpiece by folding over the roller-bearing frame R and to be able to place the finished roof tiles on shelving boards.

Before the punch goes forward again, during what time the rolling mill so much Thon must have mastered than is required to produce two roof tiles

Slide S must be inserted in its original lowest position, which is achieved by rotating the shaft w .

Claims (1)

Patent claims: i. The use of a slider S attached to the mouthpiece of a roof stone press, which by means of a screwed or otherwise fastened plate f retains the clay bead in the deepest setting for the attachment nose of the roof stone, while the attachment nose is formed in the slide itself, and which is in connection with the cutting device A. can be raised or lowered. The cutting and lifting of the roof tiles by just one rotation of the frame Ji respectively. Ji ¹ with the guide rollers lying in the same to effect the studs r and r ¹ screwed into the lugs and by means of a knife m attached to the transverse rib q ^1. For this purpose ι sheet of drawings.
