Leather dyeing machine.

Patented in the German Empire on February 27, 1890.

In the known leather dyeing machines with a rotating table, the color or stain is used absorbed by the leather only through its absorbency, by one gives up the liquid paint in the middle of the horizontally rotating tabletop and by centrifugal force distributes them over the skin stretched out on the plate. It is true that this results in a fairly even distribution of color and coloring achieved, but there is a rolling in, a mechanical pressing in, i.e. more intimate penetration does not take place. It is, therefore, evident that, if to the effect mentioned, the known Machine adding such a mechanical milling of the color into the fur is a better one and more permanent, more intense coloring is achieved. To achieve this is the purpose our invention.

We use the well-known method of staining, the color being applied to the rotating surface Tabletop spread fur is infused as required, by means of a shower or also in a stronger jet and then, by virtue of the centrifugal force, spread evenly over the skin distributed, with the addition of the pressing-in or the rolling-in of the color by the fact that we at the same time during the rotation an elastically guided pressure roller over the table and the Lead away fur, which is the possible unevenness and uneven thickness of the fur can customize ..

Fig. 3 is a vertical view, seen at right angles to Fig.

5 shows a detailed view of the color distribution tube,

6 shows a cross section through the machine in a vertical plane at right angles to the main axis,

FIG. 7 shows a basic outline for FIG. 6.

The machine consists of a frame G; in this the horizontal main transmission axis W ^{1 is} mounted, -which of suitable transmission by means of fixed and empty disk RR ¹ in respectively. can be put on operation. The vertical axis W ^{2 is set} in rotation by the shaft W ¹ by means of the toothed or friction angle gear FF ¹ , which is appropriately supported in the cross bearing K and the wall bearing Z. ⁵ , which are also attached to the frame G.

The vertical axis W ² carries at its upper end the table X ¹ made of hard rubber by being wedged on the axis W ² by means of a spider s and a hub.

About the axis W ² respectively. To be able to stop the table without putting the main axis W ¹ on operation, the wheel F ¹ on the axis. W ^{1 can be} moved by means of the fork release lever H ¹ . The switching on and off of the whole machine respectively. the shifting of the drive belt on one of the pulleys R or jR ¹ is done by the lever Η ^% and the resulting misfire.

Claims (1)

At the end of the main axis W opposite the drive disks R and R ¹ are the small disks R ² and R ³ , one of which is also firmly wedged and the other is loose. These are used to put the paint pump P into operation by means of a disk i? ⁵ with crooked pin and lever mechanism g H {, Fig. Ι and 5. By means of the pump, the paint is lifted from a container Z under the machine into the upper container V , from which the same through the tubes z ¹ and i ² on the table BEZW. can be poured onto the fur spread out on this in the form of a shower or as a strong jet at will. Excess paint can flow back to the lower container Z through a pipe r ^2. In order to collect the excess paint and to prevent it from splashing, the rotating table is placed in a box-shaped insert built into the machine frame, through the bottom of which the vertical axis W ² passes tightly. So far the machine offers nothing new, neither in terms of construction nor in terms of operation. But now, as indicated above, the poured out onto the skin rotating with the table or to mechanically press scattered paint into the fur, we have the following Improvements made to the machine: Rotatable and displaceable parallel to the axis W ¹ (in the present case), we arrange a hard rubber roller W above the table, the lower edge of which is flush with the plane of the table top or the fur comes to rest. The roller is for this purpose with its end pin in guide strips, which are arranged on the two corresponding side walls of the above-mentioned box-shaped insert, ^{slidably mounted in slots x 1} and is during operation of the machine or when dyeing a hide during its rotation over the Table moved back and forth to hammer the paint into the fur. The displacement of the roller can be on any. done appropriately. , In order to precisely adjust the roller respectively. To enable the guide strips, the latter are adjustable on screws s ^l s ² at angles w ¹ w ² , and are also ^{held elastically upwards and downwards by helical springs sp 2} and sp ⁸ so that the roller can adapt to the random unevenness can adapt to the skins. In this way we achieve a much more intensive penetration of the color into the leather and ¹ more permanent and more evenly colored skins. Patent claim: A leather dyeing machine with a rotating table, in which the color is transferred to that on the table top spread fur, in addition to the natural absorption, mechanically pressed in by it and it is drummed in so that while it is poured onto the skin and sprinkled on it an elastically mounted roller rolls over the skin at the same time.
