DRYING DEVICE.

Speccation of Letters Patent.

Patented Dec. 17', 1907.

Application filed June 6. 1907. Serial No. 377.567.

` rich-Duisberg, in the Province of Rhenish Prussia and 'Kingdom of Prussia, Germany, have invented certain new and useful Improvements in Drying Devices and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same.

This invention relates to a drying-device having several steam-plates, steam-trays or the like arranged one above the other and supported only at the circumference, each of said plates or trays being composed of several sectors each heated byv itself. In the case of these drying-devices which per se are well known, the defect has made itself felt that the plates through being supported only at the circumference in the course of time sag downwards in the middle and that then condensed water collects there, which apart from involving other disadvantages c ools down the steam and so causes a loss of heat.

Now the object of the present invention is to avoid this defect and this is eHected by giving the bottom of the individual platesectors such an inclined form that at all parts it slopes down towards the dischargepipe so that the condensed water is compelled to flow away under all circumstances.

The device is illustrated in the accompanying drawing in which Figure lis a part-sectional elevation and Fig. 2 a plan.

The device consists as is well known of a number of circular hollow plates a or trays arranged one above another said plates resting at their circumference on supports or brackets l) iXed on the two admission pipes or columns c and the alternating two discharge pipes or columns c. The pipes c and plates a are connected with each other by the inlet pipes d; and the pipes c and plates a are connected with each other by the outlet pipes CZ, each of the outlet-pipes being connected at the deepest part of a plate-sector. Arms f provided with stirring-blades g are arranged in the customarymanner around a shaft e, said blades during their rotation carrying round the material on the plates and conveying it downwards. The plates are composed in sectors of separate pieces of sheet-metal h, L/ and of corresponding frames i inserted between the latter, and are united into a complete closed member, staybolts lc being provided to hold the top and bottom plates at a given distance and to stiffen them. Now the novelty of this steamplate stove consists in each of the sheetplates h forming the bottoms of the steamplates, sloping downwards towards the outet-pipe as is shown distinctly in Fig. l, so that the deepest part is at the place where the outlet-pipe is connected, this formation of said sheet-plates 7i being obtained by the frames having a special shape. This fall or gradient consequently possessed by the inclined bottoms of the steam-plates is such that even if the steam-plates were to sag at the middle to a comparatively great extent, the condensed water would have a free exit and it would be prevented from accumulating under all circumstances.

I-Iaving now described my invention I declare that what I desire to secure by Letters Patent is:

Drying-device having several steam-plates arranged one above the other, and each being composed of several sectors each heated by itself, characterized by the bottom of each individual sector being formed sloping and with an inclination towards a part which is deepest, at which part the outlet-pipe (d) for leading away the condensed Water is connected.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
