HENRY BREER, OF DE VVITT, NEWV YORK, ASSIGNOR TO GAROLIN E H. BREER, OF SAME PLACE.

APPARATUS FOR DRYING FERTBLIZERS.

SPECIFICATION forming part of Letters Patent No. 313,401, dated March 3, 1885.

Application tiled June 19, 1 884. (Nomodeh) To all whom it may concern:

Be it known that I, HENRY BREER, of De \Vitt, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Desiccating Apparatus, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the class of desiccating apparatus which are designed more particularly for the treatment of animal matter for fertilizers, and has special reference to such of said apparatus in which the substance to be treated is carried in a revolving cylinder which is subjected to the requisite h at to expel the moisture from said substance.

The object of my present invention is to ob tain a greater and better distributed heatingsurface in and around the desiccating-cylinder and to keep the heating-surfaces clean; and to that end the invention consists of the peculiar combination and arrangement of devices connected with the desiceatingcylinder, as hereinafter fully described, and specifically set forth in the claims.

In the annexed drawings, Figure I is a 1ong'tudinal section of a desiccating apparatus provided with my improvements, portions of the desiccating-cylinder being broken away to better illustrate the internal arrangement of the same; and Fig. II is a vertical trans verse section on line no a", Fig. I.

Similar letters of reference indicate corresponding parts.

A represents the furnace in which to generate the heat required for the desiccating process.

B denotes an elongated combustion-chainber, which communicates with the furnace A, and has arrangedlongitudinally through it the revolving desiccating-cylinder G, the interior of which communicates with the combustion chamber at the end farthest from the furnace, the opposite end of the cylinder connecting with the smoke-stack D, and thus the products of combustion are made to pass longitudinally through the cylinder 0.

In order to obtain a better distribution of the heat around the exterior of the cylinder,

I form around the same a spiral partition, (1,

preferably in the form of a spiral flange secured to the cylinder. as shown in Fig. I of the drawings, said partitioncausing the products of combustion to pass completely around the cylinder during the rotation of the latter. 5 5

Lon gitudinally through the center of the cylinder is extended a fine. E, which communicates at one end with the stack D, and may have its opposite end either closed or open to convey a portion of the products of combustion from the farthest end of the combustionchamber to the smoke-stack.

From the longitudinal fine E, through the side of the cylinder, are extended radial pipes F, arranged at proper intervals in the length 6 5 of the cylinder, said radial pipes serving to convey currents of the products of combustion from the combustiouchamber to the flue E, and greatly increasing the heating-surface in the cylinder. Besides this, the radial fines '70 form arm's which serve to agitate and break up the substance under treatment.

In order to keep the described internal heatin g-surfaces of the cylinder clean, I extend longitudinally through the cylinder chains I),

and thus scour said surface, which scouring 8o process is assisted by chains d d, suspended from the longitudinal chains 1), as illustrated in Fig. I of the drawings. The surface of the radial pipes FF, I keep clean by means of chains 6 e, hung slack across the cylinder at the side of said pipes, as shown in Fig. II of the drawings. In the rotation of the cylinder the chains 6 e are dragged across the pipes and lengthwise the same, and thus serve to scour the pipes,

said chains also aiding the stirring and break- 0 in g up of the substance under treatment.

Having described my invention, what I claim as new is- 1. In combination with the combustionchamber, a rotary desiccating cylinder and a 5 smoke-flue extended longitudinally through said cylinder, adapted to carry the products of combustion from the furnace to the chimney.

2. In combination with the combustionchamber and the rotary desiccating-cylinder, a smoke-flue extended longitudinally through the cylinder and radial fines extended from the longitudinal flue through the side of the cylinder, substantially as set forth and shown.

3. In combination with the combustionchamber and the desiccating cylinder arranged in said chamber, spiral partitions between the exterior of the cylinder and interior of the combustion-chamber, as and for the purpose specified. I

'4. The combination, with the rotary desiccating-cylinder, of scouringchains connected to the cylinder and adapted to drag on the internal surface thereof, substantially as specified.

5. The combination, with the rotary desiccatingcylinder, of chains extended longitudinally through the cylinder and suspended from the interior thereof, substantially as and for the purpose specified.

6. The combination, with the rotary desiccating-cylinder, of chains extended longitudinally through the cylinder and suspended from the interior thereof, and chains suspended from the longitudinally-disposed chains, substantially as described and shown, for the purpose set forth.

7. The combination, with the rotary desiccating-cylinder, of pipes extended across the interior of the cylinder and chains hung slack across the cylinder at the side of said pipes, substantially as described and shown, for the purpose specified.

In testimony whereof I have hereunto signed my name and affixed my seal, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 26th day of May, 1884.
