FLUID 'DRIJER.

Specification of Letters Patent. Patented Jan, 16]) 11922,

Application filed May 6, 1918. Serial No. 232,972.

To all whom it may concern:

Be it known that I, RAYMOND H. Moonn, a citizen of the United States, residing at Cleveland in the county of Cuyahoga and State of (ahio, have invented a certain new and useful Improvement in Fluid Driers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings. 7

This invention relates to apparatus for drying fluids such as air and, while not limited in its application to any special apparatus, is particularly useful in connection with sand blast devices wherein the sand is directed against the surfaces to be cleaned by means of air under pressure and which air should be free from moisture in order to enable the devices and the sand to operate with maximum efiiciency. It is the gen-- eral object of the invention to provide a simple and eflicient means for removing moisture from fluids of the character referred to. I realize this object in and through the construction illustrated in the drawings forming part hereof, wherein Fig. 1 represents aperspective view of a fluid 'tlrying device constructed in accordance with my invention; Fig. 2 an enlarged vertical sectional view through such device; and Figs. 3 and 4 sectional details corresponding respectively to the lines 3-3 and 4- .1: of Fig. 2 and looking in the direction of the arrows. 4

Describing by reference characters the various parts illustrated herein, 1 denotes an outer cylindrical casing having a bottom 2 which is downwardly inclined from the cy lindrical side wall of the casing to the central portion of such bottom where a pet cock 3 is provided for the purpose of withdrawing water, or other liquid, from time to time. At its upper end the cylindrical wall 1 is flanged outwardly, as shown at {1, and this flange has secured thereto a head 5, bolts 6 and a clamping ring 7 being employed for the purpose of securing, the flange and head together. The head 5 is provided with a central aperture into which there is threaded a pipe 8. Projecting downwardly from the head and preferably cast integral therewith is an annular flange 9 to the outer surface whereof there is secured a cylindrical wall 10 which extends downwardly within thp enc whereof is spaced from the bot-tom 2 of said casing, the parts being so arranged as to provide an annular space between the parts 1 and 10.

In the operation of the device shown here-r in, the air or other fluid to be dried is discharged tangentially into the upper end of the annular space between the casing 1 and the wall 10 and in a direction to impart ahelical movement to the fluid. For the purpose of realizing this result, a pipe 11 is shown as discharging into a passageway formed in and preferably integral with the head This passageway, indicated at 12, is provided in a helical projection 13 at the top of the head 5 and preferably formed integral therewith, the head being recessed as indicated at 13 so that the passageway is,

formed in part between the upper and the lower surface of the head proper. It will be observed that the" passageway 12 is of less cross-sectional area at the discharge end thereof than at the inlet end thereof, whereby the fluid to be dried is discharged into the upper end of the annular space between the parts 1 and 1 0 at a high velocity, the inclination of the passageway and the arrangement of the parts 1 and 10 being such that the fluid is given a helical direction during its passage through such annular space, as indicated by the arrows on Fig. 2. Because of this whirling action, any moisture in the fluid will be separated therefrom by centrifugal action and will accumulate upon the casing wall 1 from which it will drain down the inner wall of such casing and collect within the bottom 2, whence it may be removed from time to time by the pet cock 3. When the whirling fluidreaches the bottom of the cylindrical wall 10, it will ascend within such wall at a relatively low velocity and passes through the tube 8 to the point of use.

By the construction described, it is pos sible', througha comparatively small and inexpensive device, to effectively dry a fluid of the character referred to and render it capable of employment asan impelling agent for sand as well as for other uses which will sug est themselves to those skilled in the art.

aving thus described my invention, what I claim is .1. In a centrifugal air drier, the combination of an outer cylindrical casing having a closed bottom, an inner cylindrical casing having its lower end spaced from the closed bottom of the outer casing and forming an annular passage with such outer casing, a.

head common to both of said casin s, said head having a central outlet theret rou h communicating with the inner casing, an a helical "passageway for air formed therewith, the inner and outer walls of said passageway extending bodily around the said outlet and said passageway being inclined toward and communicating "at its delivery end with said annular passage; whereby a helical course will be imparted to the fluid in the passageway in said head and in the annular passage formed between the inner and outer casings.

2= In a centrifugal air drier, the combination of an outer cylindrical casing having a charging into the annular passage through 30 an elongated port. a

In testimony where0f, I hereunto afiix my signature.
