Specification of Letters Patent.

To all whom. it may concern Be it known that I, ADALBERT HERMAN N, a subject of the Em eror of Austria-Hungary, residing at Vienna, Lower Austria, Empire of Austria-Hungary. have invented certain new and useful Improvements in De vices for Removing Water from Layers of Artificial-Stone Pulp, of which the following is a specification.

ing for example of about 300 kg. of dry substances and 4000 l of water it has been found that the comparatively large content of specifically heavy dry substances at once causes deposition of the latter, whereb .the water contained in the pulp rises. so t at a removal of the water downward as customary in the manufacture of paper or pasteboard is impossible.

The object of my invention is to provide means for the removal of the water from the surface of the layer formed upon the metallic cloth. In the accompanying drawing Figure 1 represents a side elevation of. that partof a machine for the manufacture of plates of artificial stone, in which the device for the removal of the water is arranged. Fig. 2 represents another mode of execution of this device.

In the drawin a designates part of an endless metallic 0 0th guided over cylinders, the rear one ofwhich is shown and indicated b b.

c is the lever formed by feeding the pulp to the metallic cloth a in a suitable place; during the movement of the metallic cloth a the heavy dry substances of the layer-settle, the water being thereby caused to rise. b. is an impermeable plate. For carrying off this water there is arranged before the cylinder b an endless ribbon d of felt or the like sucking material moved with the same velocit as the metallic cloth and directed to war the surface ofthe layer by'the roller efthis ribbon lying on the surface of the layer by reason of its own weight and bein conducted together with the metallic clot and the layer under high tension around the cylinder b. Below the cylinder 6 a further cylinder f is arranged .pressin against cylinder b and around this cylin er j the endless ribbon (1 passes carrying with it the layer for feeding the latter to a well known w nding up device notre resented in the drawing. From the cylin er 6 the endless metallic cloth returns to the feeding place.

The operation ofthe device is as follows The water on the surface of the layer is partly sucked-01f by the ribbon at before the cylinder 1) is reached by the ribbon d and the tension of this ribbon on cylinder b produces a pressure upon the layer and causes the water still remaining in the layer to be pressed out toward the ribbon d, this latter being simultaneousl squeezed, there Patented J an. 6, 1914.

by a continual removal 0 the water being secured. Over the cylinder f the homog'cn'cous layer nearly freed from water. is conveyed upon the ribbon d to the winding up device while the metallic cloth returns to the feeding place.

To increase the sucking capacity of the ribbon d a second ribbon g of felt like sucking material may be arranged in close'proximity above the ribbon d,as shown in Fig. 2, which second ribbon g, moved with the same velocityas ribbon d, takes upfrom the same part of the pulp water already sucked off thereby.

What I claim is:

1. In a device for removing water from layers of an artificial stone pulp, the combination of an endless metallic cloth running over an impermeable plate and a cylinder and carrying the layer in advance of the cylinder with a ribbon of a sucking material lyingupon the surface of the layer and guided together with the metallic cloth and the layer around the said cylinder under tension, substantially as described.

2. In a device for removing water from layers of an artificial stone pulp, the com bination of an endless metallic cloth running over an impermeable plate and a cylinder and carrying the layer in advance of the cylinder with a ribbon of a suckin material lying upon the surface of the fayer and guided together with the metallic cloth and the layer around the said cylinder under tension and a second cylinder arranged below the first cylinder and ressed againstjit, the

ribbon together with t e layer passing over the said second cylinder, the metallic cloth being separated from the layer, substantially as described.

3. In a devic for removing Water from layers of artificial stone pulp formed on an endless, movable metallic cloth, a ribbon of a sucking material conveyed close to the surface of the layer in combination with a second ribbon of a sucking material conveyed close over and with the same velocity as the first ribbon and arranged to suck from the latter a part of the Water absorbed by the same from the layer, substantially as described.

4. In a device for removing Water from layers of artificial stone ulp, the combination of an endless meta lic cloth running over an impermeable plate and a cylinder and carrying the layer in advance of the cylinder with a ribbon of a suckin material lying upon the surface of the "ayer and guided together with the metallic cloth and the layer around the said cylinder under tension and a second ribbon of a sucking material conveyed close over and with the same velocity as the first ribbon and arranged to suck from the latter a part of the tion of an endless metallic cloth running over an impermeable plate and a cylinder and carrying the layer in advance of the cylinder with a ribbon of a sucking material lying upon the surface of the layer and guided together with the metallic cloth and the layer around the said cylinder under tension, a second cylinder arranged below the first cylinder and pressed against it, the ribbon together with the layer passing over the said second cylinder, the metallic cloth being separated from the layer, and a second ribbon of a sucking material conveyed close over and with the same velocity as the first ribbon and arranged to suck from the latter a partof the Water absorbed by the same from the layer, substantially as described.

In testimony whereof I afi'ix my signature in presence of two Witnesses.
