and take-off table.

Paternity in the German Empire from March 28, 1885.

This invention aims at a secure shaping, simpler and safer cutting and removing the brick from the cutting table.

In order to be able to regulate the extruded clay strand without changing the pre-form, serves the following facility:

The roof tile shape A, Fig. 1, 2 and 3, carries under the strand in the middle of a semicircular projecting, fixed plate A ¹ ; An equally large plate A ^{2 is} attached above the strand, but it is movable where it emerges from the mold, either made of sheet metal as A * in FIG. 2 and flexible, or as A ' ² in FIG Fig. 1 rotatable in a hinge. A toggle lever A ³ , which has its pivot point on the mold plate, presses on the front end of the plate A ² and A *; By shifting the weight on it one can regulate the pressure at any moment, the loading of A ² and A * can, however, take place in place of the knee lever by placing weights directly on it.

The finished string of roof tiles runs slightly crooked or comes out of the middle of the trundle bed, as a result of which it is then cut crookedly; To prevent this, individual rollers are only made as long as the strand is wide, and small rollers B ¹ B \ Fig. 3, of larger diameter, which rotate loosely on the axis, are placed on the same axle at their ends cannot move sideways; on the one hand they give the strand a secure lateral guidance, on the other hand they also serve to prevent protruding edges which z. B. always have the interlocking tiles on one side to wear.

The movement of the cutting trolley with the string of clay in order to achieve right-angled cross-sections has so far been without exception independent of that of the cutting frame, but always in such a way that the trolley was pushed back by hand until the cutting bar was set in motion, but then started running, like this that he could roll forward with the strand, but after the cut he pushed it back again and so held on until the next cut. Both movements thus took place, although their effects were dependent on one another, each for itself and independently of the other by the cutting worker. The devices described below are now intended to make the movement of the carriage dependent on the movement of the cutting bar, but independent of the worker.
The most common cutting brackets are:
Sheet cutter, vertical cutter and cross cutter, and with all three it is important to establish a connection between the cutting bracket sitting on the carriage and the stationary base of the carriage, which connection is such that the stationary cutting bracket is prevented by this connection from continuing, but its mobility is achieved through its cutting movement and, after the cut has been completed, it is only driven back again by its final movement and independently of the will of the cutting person. This connection can be made with the three cutting

rexei

There are two types of ironing, namely a pulling or a pushing one.

2 and 3 show a tie rod C ' ² between the points C ¹ and E ¹ as a connection between the cutting bracket E and the base C , and a chain could also be used in its place. When the bracket E comes to a standstill on one side, the tensioned chain pulls the carriage back firmly; When the bracket is ^{pushed forward, the chain becomes slack as the fastening pins C 1} and E ¹ approach each other and allows the carriage to roll on until the connection points C ¹ and E ¹ on the other side move so far apart that the chain is tensioned and then with the short, subsequent lateral final shift of E, the carriage is pulled back into its original position.

4 shows two pins C ¹ C ¹ fixed on the base C and a nose E ² on the bracket E; standing on one side, the pin C ¹ on which the nose E ' ² leans firmly holds the carriage back. By pushing E sideways, the nose becomes free, the carriage moves forward until the other fixed pin C ¹ lets the protruding nose slide back again and pushes the carriage back.

Fig. 6 shows a vertical cutter E with two noses 2? ² , the lower of which leans ^{against a pin C 3;} the effect of moving E down is the same as in FIG. 4.

Of course, as in FIG. 4, E could also be provided here with only one nose which would alternately run against two pins.

Fig. 9 shows how you can ^{attach a pull rod or chain C 2} between the cutting bracket and the base for the same purpose with the vertical cutter.

Fig. 7 and 8 show how one would have to attach the pull chain to the sheet cutter, and 14 and 15, how one works with the sheet cutter by an angle C on each side of the pedestal, against which the bracket alternates starts producing the same effect.

The establishment and mode of operation of the apparatus to achieve the inevitable Movements of the cutting carriage is therefore the same pulling BEZW for all three types of ironing. oppressive.

The frame EE, Fig. 1, 2, 3, 4 and 5, carries a vertical cutting wire F, which cuts through the strand at right angles when the material is crossed. The two columns D ¹ are connected top and bottom by a pair of brackets D ^"2 with each other, each carrying a pin D ^3, on which a pair of horizontal double lever -D rotate. ⁴ This -Horizontalhebel D * umschliefsen at the rear end with a Slit the pins E \, which are stuck on EE ; the front ends of D ⁴ X) ⁴ are connected to one another by a cutting wire G. It is evident that G cuts the strand in an arc at the front end and at the same time F cuts it off at right angles at the rear end.

For the purpose of separating the superfluous respectively. The following device is used to allow the part of the nasal cord necessary for the formation of the nose to stand. ■ '.-

On the carriage is an axis H, Fig. 1, 2, 3, 4 and 5, attached, on which a lever H ¹ H * rotates, the longer end H ' ² ends up or down in a fork H ^s , between the arms of which either a wire J is stretched straight or is attached bent ^{as a bracket J 1.} Furthermore, a piece H ^{1 is} attached to the stationary table, against which the short end of the lever H ¹ is supported when the cutting carriage is at rest, keeping H ' ² suspended. As soon as the carriage starts rolling by the start of the cutting movement, H ¹ slips on H * and the wire J respectively goes. J ¹ through the nasal cord, which he had previously separated from the clay leaf, and thus the coming end of the same remains as a nose on the leaf until at the end of the cutting movement with the backward movement of the carriage, H ' ^{2 also} goes up again and from the point where the new roof tile begins again, the nasal cord separates from the leaf.

At the end of the fixed table C, Fig. 1, 2 and 3, a roller path K is again attached in the extension of the roller track of the car, which has its support and pivot point at K ¹ and a lever K ' ² with weight at the lower end is wearing which the runway K obtained in a horizontal position, until the flat cut tile by _^2/3 of its length accumulated on K. Then K leans forward and the finished roof tile rolls down quickly, hitting the drying board m underneath, onto which it automatically lays itself down in the now common forward roll and rolls towards the customer.

Cutting off the superfluous nasal cord and leaving out the Dachstein nose, regardless of whether the nasal cord comes out from under or above the leaf, can also be done in other ways, directly and solely depending on the sliding of the cutting frame E, and without any other To require handles or mechanisms, as they have hitherto been used for this purpose in the form of pawls and the like.

On the cutting carriage D, Fig. Ι ο and 11, an axis H is mounted above or below the runway, on which a lever H ² with fork i? ^s

and cutting wire J ¹ is at rest. On each side of the cutting frame E there is an inclined elevation E * in such a way that the lever H ² rests alternately on one or the other when the frame E is stationary on one or the other side of the carriage during the standstill of the bracket E, the wire J cuts the nasal cord from the cord above it; During the transfer of the frame E , the bracket slides down with the wire and the nose remains there, in order to go up again when the cross-section is completed through the roof tile and cut off the nasal cord from the roof tile that is now coming.

If you let the roof tile come out with the nose upwards, the construction changes insofar as the two elevations E * make two depressions i? ^4, Fig. 12 and 13, in which the lever H ^'2 then descends to cut the wire J behufs cutting the nose strand.

The tension or pressure connection of the cutting bow with the fixed table can also, instead directly, through the mediation of a machine part, which is done by means of wheels and levers or is otherwise connected to the bracket, as shown in FIGS. 19 and 20, for. B. from Showing a curved diagonal cutter by means of a pair of wheels. The effect is the same as with direct attack.

Since the good functioning of the mechanisms described depends on the fact that even the thinnest strand of roof tiles takes the carriage D away with it through its friction on the rollers, as soon as it regains its free mobility through the movement of the cutting bar, it follows that when this is done Cut the carriage D with the cut piece is preferred, the friction of the strand on the rollers of D would be sufficient to tear the thin strand between D and C or at least to make it unusable in its cross-section.

It is, therefore, a second condition for the good functioning of the whole mechanism that, when the carriage is in advance, the rollers under the slower moving strand do not have to advance, and this is achieved by, as Figs. 18 and 19 show, the rollers of the The cutting carriage between D and C is placed in a low frame Z) ¹ , which rests as a carriage on the front of carriage D , i.e. it follows its movements.

This carriage D ¹ carries two rear pins £) ^2, which nd Vorderwa-by going from C and terminate in two disks which, so to rest at conclusion of the cutting movement, at the beginning of the advance on the wall of C and thus the. Prevent further movement of the slide; the carriage D therefore hurries on alone. At the beginning of the backward movement, D ¹ goes back with D until it hits C , and then D, ^{sliding further under D 1} , also goes back until it hits C.

Furthermore, there is a small nose C ² , Fig. 16, 17 and 18 on the base C , which has the purpose of immediately forcing the cutting bar D into a small forward movement at the moment when the cutting bar D is set in motion and thus immediately that Persistence. able to overcome the carriage, so that the rope gliding over it takes it with it at its own speed immediately and without any loss of time or movement.

22, 23 and 24 show the different positions of the roller tracks CD ¹ and D with respect to one another in the different positions of the carriage.

With the vertical cutter and curved side cutter, the cutting bracket must be used, as one practically only cuts through the strand of clay from top to bottom, always again after the cut and. Removal of the cut pieces are lifted back to the upper original position, with horizontal and arched center cutter, the wire always only goes to a cutting job from one side of the car to the other by cutting back again.
