SPECIFICATION forming part of Lettersratent'No. 687,061,1:1atea1v0vember 19, 1901. lApplimtion filed February 11,1901. Serial No. 46,800. (No model.)

BROWN, citizens ofthe United States, and resi j dents of Coldwater, in the'county of Branch and State of Michigan,- have invented a new and Improved Drier, of which the following is a full, clear, and exactdescription.

This invention relates to improvements in driers for slurry cement, clay, or other material designed to be calcined in a kiln; and the object is to provide a drier of simple conf struction and arranged to use the excess or escape heat of a kiln as a drying medium.

We will describe a drier embodying our invention and then point out the novel featuresA in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, l

in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a partial section and partial elevation of a drier embodying our invention.

Fig. 2 is a partial section and and partial ele-` vation at rightangles to Fig. 1. Fig. 3 is a top plan view. Fig. 4 is a section on the line 4 4 of Fig. 1. Fig. 5 isa detail showinga scrapercarrying arm employed, and Fig. 6 is a section on the line 6 6 of Fig. 5.

The drier comprises a cylinder 10, at opposite sides of which are extensions or lues 11, and the device is placed upon the outlet or chimney 12 of a kiln and communicates there` with through pipes 13. Arranged within the cylinder are a number of drying-platforms 14, leach provided with an opening 15, through which material may discharge from one platform to another. These platforms extend alternately from opposite sides of the cylinder and have openings alternately vat opposite sides for the passage of heat, as clearly indi- Extended upward through the several platforms is a shaft 16, on the lower end of which is a gear-wheel 17, designed to be engaged by any suitable device to impart a rotary movement to the shaft. The shaft 16 at its lower end has connection with a collar 18, which is mounted to rotate on a block 19, and ball or roller bearings are lplaced between said collar and block. The

.upper end of the shaft has a bearing in a boxing 20,l attached to rods extendingA across the llchimney oroutlet 2l vof the cylinder.

Mounted on the shaft above each platform 14 is a scraper-carrying arm 22. These sev- 'eral arms are variously arranged as to their joutward projection, from the shaft, and it may l be here stated that the openings 15in the several platforms are arranged out of 'line one iwithianother. Mounted on the arms 22 are scraper-blades 2:3. These scraper-blades are ,curved in the direction of their movement, 'and' as here shown they are removably connected toblocks 24adjustable longitudinally on the arms andare held as adjusted by setserews Y25. While we have shown scrapers as applied to the lower arm in Fig. 2, it is to be lunderstood that they are designed to be connected to all of the arms and as many scrapers as desired may be placed upon each arm.

In operation the material to be dried is fed through the pipe 26, leading through the top of the cylinder, and falls upon the uppermost .platform 14. The Scrapers rotating over this uppermost platform will keep the material in motion, and as the material reaches the opening l5 in said uppermost platform it will pass downward upon the next of the series, and this will be continued until it reaches the lowermost platform, from which it passes through a chute 2'7 into the kiln. During this operation the heat will pass upward through one flue 11 vover the platform, thence through the opposite i'lue 11 over the next platform, and thus continueuntil it finally escapes through the chimney 2l. l

For the purpose of adjusting the parts or for cleaning the platforms when necessary the cylinder is provided with door closed openings between the platforms.' @It will be noted that the arms 22 are adj ustably connected to the shaft 16 and may be held as adjusted vertically thereon by means of setscrews.

A device embodying our invention may be economically operated, because it uses waste gases or heat from the kiln, and as the material will be in comparatively thin layers it IOO Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. A drier adapted for connection with the heat-escape iiue of a kiln, and comprising a cylinder having vertically-arranged extensions forming fiues at opposite sides, a series of platforms arranged in the cylinder and extending alternately from opposite sides thereof at the extensions, and terminating alternately at opposite sides at the ilues forming openings for the passage of heat, each of said platforms having an opening for the discharge of material, a shaft extended upward through the partitions, an arm on the shaft above each platform, and scraper-blades carried by the arms, substantially as specified.

2. In a drier, a platform having an outlet, a shaft extended through the platform, an arm adjustable at one end on the shaft and having a T-shaped portion, a block adjustable longitudinally on the T-shaped portion of the arm, and a curved scraper removably connected to the block, substantiallyas specified.

3. A drier adapted for connection with the heat-escape outlet or chimney of a kiln, and comprisinga cylinder having an outlet at its top and pipes at its lower end arranged t-o communicate with the said outlet of the kiln, the said cylinder being provided with vertically-arranged offsets or extensions at opposite sides forming iues, a series of platforms arranged in the cylinder and extending alternately from the walls of the fines at opposite sides and terminating alternately at the said fines forming openings for the passage of heat, the said platforms being each provided with an opening for the discharge of material, a'`
