CLASS 68: Pressing.

Patent addition to No. 21369 of May 16, 1882.

Patented in the German Empire on December 7, 1882. Longest duration: May 15, i8g7.

The main parts of the packing press with screw and lever drive shown in the accompanying drawing consist of the top with movable side walls and the wooden lower box α and a ¹ made of fixed walls, which are used to hold the material to be pressed, with the movable bottom c and the lid g.

Furthermore, from the two cast iron brackets h and h ¹ , which receive the drive shafts b and b ¹ and the chain pulleys e and e ¹ , and one of the latter is provided with a conical gear i on its lower surface, into which the pulleys y moving conical drive i ¹ engages.

An endless link chain moves around both chain pulleys e and e ¹ and causes both chain pulleys and drive shafts b and b ^{1 to} work evenly. The latter are on _; their lower ends are provided with conical gears k and k ¹ , which engage in the conical gears / and I ^{1 of} the screw spindle m provided with right-hand and left-hand threads and cause them to rotate.

The two nuts η and n ¹ move on the spindle m , in which, on the one hand, four levers 0 ¹ O ¹¹ O ¹¹¹ O ^{1111 are} mounted and, on the other hand, with the movable floor c and with the fixed cast-iron plate mounted on the long sleepers w / and cause the floor c to move upwards.

The drive shafts b and b ¹ and the screw spindle m are mounted in the two bearing blocks q , and the latter are guided between two T-irons r and r ¹ when the floor and the screw spindle are moved upwards.

The packing press with screw and lever drive works as follows:

The lid g , which is provided with two wooden pressure bars, is turned over to one side until the iron tie rods ί have placed themselves on the arms t on the cast iron frames h and h ¹ and the entire opening of the upper case α is exposed. The lower and upper boxes are then filled with the material to be pressed (peat litter, wool, etc.), and the cover g is moved back to its previous position so that box a is closed again.

When the press is driven, the chain pulleys e and e ¹ rotate through the conical gears i and i ¹ attached to one side and thus cause the drive shafts b and b ^{1 to} move upwards as well as the rotation of the screw spindle m, through which the nuts η and η ^! converge towards the middle and the levers ο ¹ ο ¹¹ o ^UI o ^{Iln are positioned one} above the other, so that an upward movement of the bottom c takes place, which exerts the pressure on the material.

The four levers ο ¹ ο ¹¹ ο ^ΙΠ ο ^ππ are so inclined in the rest state that climbing is easily made possible with the aid of the two springs u and u ^1.

In order to prevent the screw spindle m from overturning, both when it is pushed out and when it is at rest, the screw spindle m is missing in the middle and the thread at both ends, so that both nuts can move on the spot without running any further, and become the nuts when the same have expired on the ends of the screw spindle, pushed onto the thread by the two springs u and u ¹ in the middle of the screw spindle by the spiral spring χ.

The T-irons r and r ¹ , between which the bearing blocks q and q ^{1 have} their guidance, are attached so that a connection respectively. Dismantling between the bearing blocks h and hi and the fixed long sleepers w takes place. The pressed bale is after the brackets of the upper box α and the. movable walls of the same has laid apart, easy to lace and take out.

Claims (2)

P ATENT claims: i. The pressing of the material in the upper box α (peat litter, wood flour, wool, hede, etc.) from bottom to top, or vice versa, by means of a screw spindle m with right and left threads, the nuts η and n ^{1 of which} with four levers ο ¹ ο ¹¹ o ^m o ^lin are connected, the latter c with the ground and w related to the fixed longitudinal ties, with the device in which rotation of the screw spindle DAF m by provided with gear wheels drive shafts b and l · ^1, the nuts η and n is ¹ move together and apart on the screw spindle m and thus a rise or fall of the four levers and the floor c is made possible and the latter exerts the pressure on the material in the upper case α , whereupon the walls of the upper case a are opened after the iron locking clips of the upper case a are released , the bale can be laced and easily removed. 2. The prevention of overturning of the screw spindle tn by the fact that the screw spindle m has no thread in the middle and on both ends, so that when the nuts η and n ^{r have} expired they appear towards the middle or towards both ends of the screw spindle m Turn the point without running any further, and pulled respectively by the springs u and u ¹ and the spiral spring χ on the thread of the spindle. be pushed. For this purpose I sheet drawings.
