Specification of Letters Patent.

Application filed May 4, 1911. Serial No. 625,059.

To all whom 'it may concern Be it known that I, CHARLES E. GEIGER, a citizen of the United States, residing at Louisville, State of Kentucky, new and useful Improvements in Driers,

have invented certain of which the following is a specification.

` discharge it from the other.

This invention relates to driers more particularly designated and described as rotary driers, comprising a rotatable cylindrical member in which a number of steam pipes are positioned, and being adapted to receive the'materal to be dried at one endvan'd to In the accompanying drawings,-Figure 1. is a longitudinal sectional view of the preferred embodiment of my invention. Fig. 2 is a cross sectional plan view through the manifold in the dischargeend of the cylinder. Fig. 3 is a detail view of one of the deflector plates positioned in the discharge .endof the cylinder.

Driers Yof this class are employed to remove themoisture .from grains, 'herbage and the like, and when used to dry grasses or herbs, it is necessary to make somev provision for the disposal of the stems or particles which are too large to pass readily between the tubes, and which tend to clog up'the passage-ways unless theyl are ejected from the cylinder. .The cylinders are generally provided fth apertures near oratthe discharge end thereof through which the smaller particles or grainsl may pass, and the present invention has for itsobject more particularly to provide means v'to eject material through the end of the cylinder between the spokes of the manifold. It is also necessary when treatin grasses or the like, to provide anentrance c amber, in which the stems or larger'particles may not become clogged between the tubes of the drier. The central drying tubes are therefore shortened in this in the countyof Jefferson andV 'an axial chamber 19 and four spoke-like end' of the cylinder. Referring now more particularly'to the drawings, a cylinder 6 is provided at one end with a ange T slightly larger in diameter than the cylinder and having communication with the cylinder by means of openings 8 in the walls thereof, and at the other end withv a manifold 9 to which is secured a ange 10. The cylinder 9 is adapted to be mounted by means of these ianges 7 and 10 so that it may be rotated. labout an axis through its center, suitable bases 1l and l12 being pro vided at the ends with means rotatably to mount the cylinder thereon. Any suitable driving means maybe employed to rotate .the cylinder upon its bases. In thepresentexemplication'of the invention, the flange 10is provided with teeth which. mesh with the teeth ina pinion 13 mounted on ,a shaft 14 and having suitable gears 15 in connection with the shaft to eect the rotation of the pinion 13 and ofthe cylinder 6. One end of the cylinder will be hereinafter designated as the inlet end and the other as the discharge end. The discharge end is provided with a manifold 16 secured tov the-cyl inder 6 and having a plurality of tubes 17 secured in Jthe manifold through the inner side and communicating with the interior thereof. This manifold is shown in section in Fig.' 2, and Ain the form shown is provided with four peripheral chambers 18,

connecting portions 2Q between the axial chamber and the peripheral chambers,

although it is to be understood that 4any del sired number of peripheral chambers may be employed. Each peripheral chamber is conL nected from its forward end (assuming the direction of rotation of the cylinder to be in a clock-wise direction) with a passage 21 which communicates with the interior of the Patented Feb. 11, 191s.

drier to provide a greater space at the inlet sol axial chamber 19.' The rear end of each pe.-

ripheral chamber is closed from. such communication and is lprovided with a pipe 22 which extends adjacent -the center of the axial chamber 19 and from there extends v outwardly into a chamber 23 which is secured to the manifold and is adapted to re'- ceive the water of condensation which may be delivered by thesaid pipes 22. This chamber 23 is formed with an enlarged portion 24 into which thewater of.' condensation from the pipes 22, is collected, a removable i plate 25Xbeing provided'to cover an opening into the said chamber. A steam pipe connection 26 is adapted to be inserted inthe end of the chamber 23, and suitable packing 'devices 27 are provided to make the connection between the steam pipe connection 26 and the chamber 23 substantially steamtight. This steam pipe connection 26 is provided with openings in theends through which a pipe 28 extends, the inner end of the pipe being adapted to extend also through the chamber-23 and into the axial chamber 19 of the manifold. Inserted in the steam pipe connection 26 and having communication with the ,hollow interior thereof are tubes 29 and 30, the latter of which is positioned so as to project into the enlarged portion 24 of the chamber 23 while the former is adapted to afford communication between the interior of the steam pipe connection 26 and the exhaust connection. This exhaust -may be either ic the atmosphere, to a waste pipe or drain, or to a steam trap, whichever is desired. In the outer surface of the manifold 16 and opposite the ends of the tubes opening into the manifold are removable plugs 31, which are adapted to afford communication with the interior of the manifold adjacent the ends of the tubes 17. The axial chamber 19 is also provided in the present exemplification of the invention with a number of tubes 32, which are secured in the inner face of the said chamber and which extend toward the outer end of the cylinder. These tubes are provided at the other'end with removable plugs 33 which are adapted to close the ends o the tubes and are-adjustable for the purpose of allowing fluid to escape from the tubes. These tubes 32 do not extend to the inlet end of the cylinder 6 and are supported intermediate of the ends by means of the perforated plate 34, which is positioned in the cylinder by means of rods 35 extending through the shell thereof and secured by nuts 36 orfother suitable means. The discharge end of the cylinder is also provided with a housing 37 preferably secured to the flange portion 7 extend-` ing beyond the manifold and providing a conveying means for material which escapes from the cylinder through the openings 8 adjacent the end of the cylinder. By reference to Fig. 2 it will be seen that the opening 8 extends around the manifold 16 on all sides, permitting the continuous escape of material from ille cylinder through the said opening when the cylinder is rotated.

Extending inwardly from the manifold 16 and positioned between the pipes 17 and the pipes 32 are deflectors 38. These deflectors may be formed integrally with the manifold, or may -be attached thereto in any suitable manner, and are formed wit-h a wide mouth portion 39 narrowing gradually toward the base to form a scoop or deliecting plate so that as the cylinder is rotated, the material I inside the cylinder and adjacent the discharge end will be scooped into the deflectors 38 and will be ejected from the cylinder through the end thereof between the spokes of the manifold 16, falling into the project- .ing part of the housing 37.

A conveyer 40 is positioned at`the discharge end of the cylinder and as the cylinwhich is also provided with plugs 31 similar to the plugs in manifold 16. A 'feeding hopper 41 1s also provided at the inlet end of the cylinder in the bottom of which is a spiral conveyer 42 adapted toconvey material from the hopper into thev inlet end of the cylinder 6, and separated from the hopper by a partition 43 is a vapor passage 44 through which vapors arising from the heated material in the cylinder may escape therefrom. Any suitable driving means may be employed to rotate the conveyer 42, it

being found that the material lmust be fed to the conveyer at different speeds, depend ing upon the kind of material to be dried.

A yoke 45 connected to the manifold 9 extends toward the hopper and forms a retaining shield for preventing the loss of material at the inlet end of the cylinder and also to prevent the escape of vapors in any vother way than from t-he vapor passage 44.

It is evident that when the drier is used to dry herbage and the like, the stems or particles that are too large to pass between the tubes 17 and out of the cylinder by way of the discharge openings 8 will be deflected by 'the deectors 38 and ejected from the cylinder, thus preventing the stems from clogging the discharge. end of the cylinder and preventing the discharge of the dried material. The openings 8 may be omitted if desired.' It will also be seen that with the applicants construction an enlarged chamber is formed at the inlet end of the cylinder by reason of the tubes orpipes 32 extending only part ofthe way toward the inlet end, thus forming a central space or chamber in .the inlet end, thereby preventing the material which is fed tothe drier from clogging this end of the drier.-

Steam or other drying liuidis admitted to the manifold 16 through'the pipe 28 and the tubes 32 are freely mounted at -t-heir other ends `to permit them to extend longitudinally, independently of the other tubes 20 rotated.

Locaceo 'the enlarged portion 24 of the chamber 23 j and is discharged therefrom through the steam pipe connection 26 and thepipe 29.

If this ipe 29 is connectedto a ste-am trap, the disc arge'of water is automatic, but any desired means of discharging this water may be employed.

I desire not to be limited to the exact construction, combination and arrangement of theseveral parts of my invention for it is evident that those skilled in the arts to which this invention pertains may make various changes therein without departing from the spirit and scope of my invention.
