AN D CHARLES CENTRIFUGAL MACHINE.

SPECIFICATION forming part of Letters Patent No. 744,659, dated November 17, 1903.

Application filed June 12, 1903 Serial No. 161,239. (No model.)

in a whom it may concern:

Be it known that I, JAMES A. WILLARD, a citizen of the United States, residing at Chattanooga, in the county of Hamilton and State of Tennessee, have invented new and useful Improvements in Centrifugal Machines, of which the following is a specification.

This invention relates to certain new and useful improvements in centrifugal maro chines. v 1

The in vention aims to construct a centrifugal machine which is especially adapted for the continuous extracting of liquid from cotton or wool'and is so constructed as to constantl y receive the material Whichis fed thereto in a uniform manner, extracting the liquid therefrom, and delivering the material after it has been operated upon out of the machine without having to make the necessary stops for theloading and unloading of the material, therefore obtaining a great saving'o time and labor. I I

The invention further aims to construct a centrifugal machine for the continuous extrac'ting of liquid'fro'm cotton or wool which shall be extremely simple in its construction,

strong, durable, efficientinits operation, and I each'providedwith openings which register comparatively inexpensive to set up.

With the foregoing and other objects in view the invention consists of the novel combination and arrangement of parts hereinafter more specifically described, illustrated in the accompanying drawing, and particularly pointed out in the claims hereunto appended.

In describing the invention in detail reference is had to the accompanying drawing, which illustrates a sectional elevation of my new and improved centrifugal machine.

Referring to the drawing by'reference characters, l denotes a hollow supporting-base, which forms a receiving-chamber 2 for the treated material andis provided with a closed bottom 3 and a top 4, having an "annular inlet-opening 5. The top 4 is formed with a laterally extending supporting flange 6, vwhich is continuous, and the top 4 is further providedat its inner side with an upwardlyextending continuous flange 7, havinga concave groove in its upper face, as at 8. The

base 1 is preferably cylindrical in contour, although any other preferred shape may be employed, and is provided with a suitable opening, so that the treated material can be exhausted therefrom in any suitable'manner.

Mounted upon the base 1 isa cylindrical casing9, which is adapted in a manner as herein set forth to forma chamber 10 for collecting the water. The casing 9 also forms what may be termed a support for various parts of the machine and is provided at its the casing 9 and substantially parallel with a portion ofthebracket15isasubstantiallyforkshaped bearing-bracket, as well as a supporting-bracket 16. The brackets 15Yand 16 are with each other, as indicated by the dotted lines 17, and through these openings is adapt; ed to extend a driven-shaft 18, having connected to its outer end an adjusting-screw 19, which extends through a part of thebracket 16 and is connected to the shaft 18. The latter carries on its inner end a cone-shaped pulley 20, the latter forming a friction-drive in a manner as hereinafter set forth. The

pulley 20 is secured upon the shaft 18 by means of the fastening device 21. Mounted upon the shaft 18 is a drive-pulley 22, which is operated by means of a belt 23,'driven by the pulley 24 upon the drive-shaft 25. The latter atits inner end is supported by the boxing 26, mounted on the flange 11, and at its outer end is supported in a standard 27.

The reference character 28 denotes a cylinder which is perforatedthro ughout and open at its top and bottom, so there will be no interruption to the material when it is fed to the cylinder or discharged therefrom. This is essential, for the reason that cotton and wool have a tendency to hang together. Consequently if there were anything extending over the mouth of the cylinder or the open bottom thereof it would cause the same to become choked up. The cylinder 28 is arranged within the casing 9 and is supported at its bottom upon the flange '7 and projects slightly within the opening 5 of the top 4 of the base 1. The manner of supporting the lower end of the cylinder 28 is as follows: To the outer face of the cylinder is secured an annular band 29, substantially L-shaped in cross-section, and has its lower face provided with a convex-shaped groove 30. The grooves 8 and 30 register with each other and form a ball-race in which are mounted the bearing-balls 31. The cylinder 28 then, through the intervention of the band 29, rests upon the bearing-balls 31. The upper end of the cylinder 28 is supported upon the inwardlyextending flange ofthe casing 9, and the manner of supporting the cylinder28 is as follows: The top of the cylinder 28 has secured thereto an annular collar 32, having its upper face beveled, as at 33, and provided with the depending lug 34, the latter being secured to the cylinder 28. The collar 32 is of such width as to project a suitable distance over the top of the cylinder 28 and to further project laterally therefrom. This lateral extension of thecollar 32 rests upon the supportingfiange 12, or rather upon the bearing-balls 14, the latter also bearing against the outer face of the depending lug 34. The beveled surface 33 of the collar is adapted to be engaged by the cone-shaped pulley 20, so that when motion is imparted to the shaft 18, carrying the cone-shaped pulley therewith, the engagement between the pulley and the beveled surface 33 will cause the cylinder 28 to be revolved.

Arranged approximately cent-rally of the base 1, in the bottom thereof, is a box or journal 35 for the lower end of the vertically-extending shaft 36. The shaft 36 extendsnpwardly through the base 1, the cylinder 28, and the free end of the bracket 15, the shaft 36 projecting a suitable distance above the bracket 15 and carrying on this projecting end a drive-pulley 37, which is operated by means of the belt 38, the latter passing over the idler-pulley 39, supported by the bracket 16, and then downwardlyover the drive-pulley 40, mounted upon the drive-shaft 25. The shaft 36 carries a spiral conveyer 41, the width of the same being such as to extend from the periphery of the shaft to almost the inner face of the cylinder 28, or, in other words, the width of the conveyer 41 is such that it extends from the periphery of the shaft to near the inner face of the cylinder 28, so that it will just clear the latter when the conveyer is operated. The length of the conveyer is such as to extend from the lower end of the cylinder 28 to very near the top thereof.

The shaft 25 is provided with the fast and loose pulleys 42 43, respectively connected with a suitable prime mover.

The chamber 10, hereinbefore referred to, is formed by the cylinder 28 and casing 9 and has communicating therewith the wastepipe 44.

The machine is provided with a feed-table for the material, and is indicated by the reference character 45. The table 45 rests upon the top of the casing 9 and is further supported by the vertical standard 46. The table 45 is provided with a conveyer-belt 46, operating over the rollers 47. The table 45 is also provided with a feed-roller 48 and guide-board 49. The roller 47 at the inner end of the feed-table 45 is of such diameter as to cause the conveyer-belt 46 to extend slightly over the inner edge of the collar 32, so that the material will pass directly into the cylinder 28 in an uninterrupted manner. One of the rollers 47 is driven in any suitable manner so as to impart motion to the conveyer-belt 46. it

The construction and arrangement of th operating means for the cylinder 28 and the spiral conveyer 41 are such that the conveyer will operate in the same direction as the cylinder 28, but at a slightly-greater speed.

The operation of the machine is as follows: The material is spread in an ordinary manner on the conveyer-belt 46, and when motion is imparted thereto the material is delivered between the inner roller 47 and the feed-roller 48 and falls by gravity into the cylinder 28, it being understood that the cylinder 28 and spiral conveyer are operating. The latter is driven in the same direction as the cylinder 28, but at a slightly-greater speed. The contrifugal force immediately draws the material to the inner surface of the cylinder or basket. The result is that the conveyer gradually works the material down until it is delivered out of the cylinder 28 in the chamber 2, where it is exhausted by any suitable means. It will be stated that the difference in speed between the cylinder 28 and spiral conveyer 41 is regulated so as to deliver the material at any given time or to allow the material to have sufficient time in the cylinder 28 to properly remove all liquid from it. It will be evident that if the cylinder 28 and spiral conveyer 41 were traveling the same number of revolutions the material would remain in the machine; but as soon as the travel of the spiral conveyer 41 is faster the material is gradually worked down and out. On the other hand, if the spiral conveyer 41 were stationary and the cylinder 28 traveling at a great speed, which is necessary to extract the water, the material would be passed through so quickly that it would not have sufiicient time to remove the liquid. Consequently the best results are obtained by running the spiral conveyer 41 at only sufiicient additional speed to deliver the material in its best condition.

It is thought the'm'any advantages of my new-and improved centrifugal machine for.

the continuous extracting of liquid from cotton or wool can be readily understood from the foregoing description, taken inconnection with the accompanying drawing, and it will furthermore be evident that changes,va-

riations, and modifications can be resorted to described and as shown in the accompanying drawing, but reserve the right to make such changes,variations,and modifications as come properly within the-scope of the protection prayed.
