GUSTAV MÜGGE in PLAGWITZ near LEIPZIG. Automatic cutting device for brick, lignite and peat machines.

Patented in the German Empire on November 22, 1877 ^a t>.

The purpose of the apparatus is to cut the string that comes out continuously from a brick, lignite or peat press into certain pieces, in Thon mostly due to the brick format, which are then removed and transported to the drying area on transport trolleys. The cut is effected by two or more steel wires in such a way that they are stretched over the upper part of a frame sliding in guides and cut through the strand when the latter is pulled down. In order to be able to grasp and lift off the cut pieces or stones comfortably, it is necessary that a space of about 100 mm is created between these and the following strand, which is achieved by the fact that the front part, the run-up plane formed by rollers is set on wheels and forms the carriage designated in the drawing with C , which allows a forward and backward movement on rails and which must be advanced after the cut has been made in order to produce the aforementioned gap. After removing the stones, the frame is now lifted up to bring the wires back above the strand and in this position the carriage is pushed back again until the strand is advanced again to such an extent that, by pulling the frame down again, respectively. the wires, in turn, stones can be cut off. These movements, namely the pulling down of the frame BEZW. the wires for cutting the cord, pushing the carriage forward, then lifting the frame and pushing the carriage back to its starting point, which are now carried out by humans, this apparatus is supposed to carry out automatically, whereby on the one hand there is a reduction in the number of men operating the machine, on the other hand but also the efficiency of the machine, which is partly dependent on the good will of the workers or their skill, is considerably increased. This task is now solved in the following way.

When the strand is continuously pushed forward on the roller plane, it encounters a movable flap Ca attached there at the end of the carriage C and, since the same is held in a vertical position by the approach C b on the flap link C c and the guide G b, a Make carriage C move forward. However, this also affects the link D b , which is also attached to the carriage C , and with it the lever D, in such a way that its lower end D c , which forms a release fork, is pulled off a coupling part Ea correspondingly toothed on both sides, so that the spiral spring E b mounted between this and the spur gear E c comes into effect and E α presses into the coupling piece Ed , which is analogous to it but firmly connected to the drive shaft, whereby the coupling appears to be closed and E a has to make the rotation caused by Ed . Since, however, the spur gear Ec with Ea also forms a toothed coupling which, however, does not come into engagement due to the lateral displacement of Ea , the gear E c must also follow the movement emanating from E d and transmitted by E α. This sets a spur gear A in motion, which, cast on one side, carries a curved disc Ac, Ad, Aa and A b for moving the cutting frame, while on the other side there is a screw washer B , which regulates the further movements of the carriage. At the beginning of the rotation of A , the previously on the, with the spur gear concentric curve A d resting roller O α is lifted by a projection A α located at the end of this curve, and, since this is fixed to the lever O and this in turn is connected to the handlebar Fa with the cutting frame F , the latter also. The lower part of the frame is formed by two angled rails F b, which on their upper edge, i.e. facing the strand, carry weak knives Fc that extend over the entire width of the carriage, the latter penetrate into the strand resting on top with this upward movement of the frame approx. 5 mm deep, in exactly the same places where the wires that cut through from above will later emerge, so that the counter-cut is made, which prevents the lower edges of the strand from being carried along when cutting through, which is at

is actually more or less the case with the apparatuses of this kind now in existence. After this process, the downward movement of the roller; O α occurs immediately, since with the further rotation of A it passes the curve A b , which also forces the frame and with it the wires, likewise this movement After the cut has been made and while the cutting frame remains in its lowest position, the forward movement of carriage C, which up to now has received this for the most part from the pressure of the advancing strand, is taken up by screw washer B by the ascending curve it comes into contact with the roller D e attached to the lever D , pushes it back and communicates the forward movement of the upper lever arm brought about by means of the handlebar D b to the carriage C and regulates this in such a way that the gap of approx .ioo mm is created. However, this shifting of the carriage also causes its flap to slide nlenker Cb over the sliding surface G b , while at the same time the pin G a attached to the sliding block engages in a 45 ° inclined guide slot Cc of the flap handle, causing a rotation of the flap Ca so that it comes to lie horizontally and the removal of the stones is not a hindrance, which situation is reached at a quarter of the revolution of the spur gear A ' . During the time it takes for the spur gear to complete three quarters of its turn, the pieces must now have been removed; because at this moment the curve A c of the cam plate meets the roller O α which mediates the movements of the cutting frame and lifts this and with the same through O and F α also the cutting frame quickly upwards, in which it then by the run-up of the roller O α is obtained on the centric curve A d , while at the same time the roller D e on the lever D reaches the highest point of the curve of the screw washer B and passes the sloping curve, so that a weight D α also attached to the lever D is put into position is to withdraw the carriage C at the speed regulated by the descending curve to its starting point. Shortly before it arrives at this or before the spur gear A turns once, the release fork D c will come into contact again with the coupling part E a and shift it laterally to E c and thus cancel the coupling connection with Ed , so that the. whole mechanism comes to a standstill until the release fork is pulled off Ea again by the pressure of the strand on the flap Ca , whereupon the processes just described take place again. In order to clean the wires that cut through the strand from the fibers etc. which are attached with each cut, a brush H is also attached above the working frame, which the wires must pass when the carriage moves backwards, where they are in their highest position.
