PATENT OFFICE.

The present automatic cutting apparatus for brick presses of all types is as follows Wise set up:

The extruded clay b emerging from the mouthpiece α of the brick press first runs onto the roller c, which is mounted on the base frame d. From here, the rope b runs on the rollers C ₁ C ₂ C ₃ to C ₉ , which are mounted on the carriage e. As soon as the thong strand b has reached the support lever /, the latter is pushed forward by the pressure of the strand b and the cutting bar g, which is mounted in the middle of the carriage e , is triggered. At the same moment the cutter bar g, on which the three wires Yi ₁ h% h _{s are} tensed, cuts through the thong b by means of the counterweight i and the cutter bar g is in the punctured position (see Fig. 2).

Immediately after the cut, a pressure roller y attached to the cutter bar g , which still makes a short distance, triggers the catch lever f _x attached to the underframe d , whereupon the weight lever k, which is attached to the shaft I , falls down (see Fig. Fig. 1).

On the shaft I now sits a gear segment m ; the same engages in the gear n, whereby the shaft 0 is rotated with the roller ρ forward. The pulley ρ is now connected to the carriage e by means of the rope qu and the latter is quickly pulled forward on the rails r and r _x as a result of the rotation of the pulley ρ. As a result of this forward movement of the carriage e, the loose roller coupling s, which is connected to the carriage e , is engaged on the shaft f in the coupling sleeve u by means of the spiral spring ν. At the other end of the shaft 0 there is now a conical pair of wheels x, which impart the opposite rotation to the shaft t. The roller coupling 5 with the coupling sleeve u, which the latter moves with a groove and spring on the shaft ί, are still in engagement by the spiral spring ν.

Now, the weight lever Ar, and the cut strap is g by means of a by a transmission moved up and down lever A in the old location accommodated, namely this is achieved, the hook A DAF in the forward movement of the carriage e by a beöndlichen on the latter arm B is hung under the pin C of the weight lever k as soon as the hook A comes down. The spring \ located behind the support lever f locks the cut-off bracket g and the spring ^ ₁ located behind the catch bracket J _x that of the weight lever k in the old position. The roller ^ ₁ with the counterweight I ₁ holds the carriage e steadily (after every step) against the rope.

The handling as described above results in that in the main patent

No. 53948 declared work to be discontinued by the worker's movement and will, as here declared, replaced by transmission operation.

Claims (1)

Patent claim: At the under No. 53948 patented automatic cutting-off device replacing the dead weight of the worker and the footboard with the weight lever k, the catch lever f _x of which is triggered by the roller y attached to the cutting bar g and which is returned to its old position by the hook A , which is moved up and down by means of transmission operation .
