HENRY M. GOODMAN, OF LOUISVILLE, KENTUCKY.

CENTRIFUGAL SEPARATING-MACHINE.

Specification of Letters Patent.

Patented Feb. 15, 1910.

Application filed April 23, 1908. Serial No. 428,771.

To all whom it may concern:

Be it known that I, HENRY M. GOODMAN, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Centrifugal Separating-Machines, of which the following is a specification.

This invention relates to improvements in centrifugal separating machines and the primary object of the invention is to provide an improved simple, durable and effective machine of this character, particularly adapted for clarifying liquids by separating the solid matters therefrom to produce a clear solution.

A further object is to provide an improved casing for the machine into which the clarified liquid, as well as the sediment may be discharged without becoming mixed with each other.

To theattainment of these ends and the accomplishment of other new and useful objects, as will appear, the invention consists in the features of novelty in the construction, combination and arrangement of the several parts hereinafter described and claimed, and shown in the accompanying drawings, illustrating an exemplification of the invention and in which- Figure 1 is a vertical sectional view on line ll of Fig. 2, showing an improved device of this character constructed in ac cordance with the principles of this invention. Fig. 2 is a horizontal sectional. view on line 2- 2 of Fig. 1. Fig. 3 is an enlarged detail sectional view of a modified form of the invention. Fig. l is a detail perspective view of one of the cylinders showing the improved manner of supporting the cylinders. Fig. 5 is a detail sectional view on line 55 of Fig. 6, of one extremity of one of the cylinders showing another form of closure for the cylinder. Fig. (3 is an end elevation of Fig. 5. Fig. 7 is a detail sectional View similar to Fig. 5 of another form of closure for the cylinder.

Referring more particularly to the drawings and in the present exemplification of the invention the numeral 10 designates a vertical shaft which is preferably provided with reduced extremities 12, 13, and a reduced portion 14 adjacent the extremity 13 to form a circumferential shoulder 15.

A receptacle 16 is provided with an aperture in the bottom thereof into which the reduced portion 14L projects so that the recep tacle will surround the reduced portion 1i and rest upon and be supported by the shoulder 15. Any suitable means may be provided for causing the receptacle 1.6 to rotate with the shaft 10, such, for instance, as a locking key 17.

The body portion of the shaft intermediate the reduced extremities may be of any desired diameter and length and surrounding this enlargcd portion of the shaft are a plurality of concentric rings 18, 19, which may be of any desired height and these rings are spaced from each other and supported for rotation with the shaft 10 in any desired or suitable manner, preferably by means of tiebolts or rods 20, which extend through the rings intermediate their upper and lower edges with the heads 21 of the bolts preferably resting against the periphery of the outer ring 1.8 and the inner extremities of the bolts are detachably secured to the shaft 10, preferably by being threaded thereinto. These rings are each provided with a plurality of apertures 22, 22-3, the apertures 22 .in the outer ring being arranged in alinement with the respective aperture 2 3 in the inner ring 15). These apertures may be of any desired diameter preferably of a diameter slightly larger than the diameter of the separating cylinders 2t, which latter are supported by the rings 18 and 19 by being passed through the registering or alined apertures therein and the rings are so spaced from each other that the extremities of the cylinders will project beyond the respective rings.

Each of the cylinders has a closed end 25 and is preferably provided with an enlargement 26 extending beyond the periphery of the cylinder and having conununication therewith adjacent the closed end. These enlargements are each provided with an aperture 27 adjacent the closed end of the cylinder into each of which is inserted one extremity of an outlet or discharge pipe 28. The. closed end 25 of each of the cylinders is provided with an aperture 29 which is preferably located adjacent the diametric center thereof and projecting into the cylinder through the opening 29 is an inlet pipe 30 which preferably terminates adjacent the closed end of the cylinder and this pipe 30 is connected to a supply pipe 31, which latter has communication with the receptacle 16 through the bottom thereof. These pipes 30 are preferably provided with detachable connections whereby the pipes may be readily removed when desired.

The outer ends of the cylinders 24 are provided with suitable closures and in the exemplification shown in Figs. 1 and 2, the closures are in the form of caps 32, which are threaded onto the outer extremities of the cylinders. In the exemplification of the invention shown in Fig. 5 the outer extremity of the cylinders is also closed as at 33 in a manner similar to the inner extremities of the cylinder and the end 33 is provided with a plurality of apertures 34. A damper or closure 35 is rotatably mounted upon the extremity 33 by means of a suitable fastening device 36, such as a bolt or the like which passes through the extremity 33 and also the closure 35. This closure 35 is also provided with a plurality of apertures or openings 37 similar in number and configuration to the apertures 34 in the end 33 so that the apertures in the closure and the end of the cylinder may be brought into alinement to permit the material to be dis charged and when the closure is rotated upon the fastening device 36 as an axis, the solid portions of the closure may be brought to a position to close the openings in the extremity 33.

The shaft 10 is mounted for rotation within a suitable receptacle 38 in such a manner that the extremity 12 thereof will pass through the bottom of the receptacle, as at 39, which portion of the receptacle is shaped to form a bearing for the shaft and the enlarged portion of the shaft is stepped as at 40 into the bearing 39.

Secured to the extremity of the reduced portion 12 of the shaft is a suitable gear wheel 41 by means of which the shaft 10 may be rotated in any desired or suitable manner, preferably through the medium of an intermeshing gear 42.

The bottom 43 of the receptacle is provided with a depressed portion 44 which surrounds the bearing 39 and the extremity 12 of the shaft 10, and an upwardly projecting flange 45 which also surrounds the bearing 39 in the extremity 12 of the shaft 10 to form a receptacle 46 which is provided with an outlet in the bottom thereof to which is connected a discharge pipe 47.

The flange 45 may be of any desired height but preferably of a height to terminate below the cylinders 24 and in close proximity to the lower edges of the rings 18 and 19. The outlet ends of the discharge pipes 28 are located within the receptacle 46 and terminate preferably adjacent the top thereof so that the clarified liquid which passes out of the pipes 28 will be discharged into the receptacle 46 from which it may be conveyed by means of the pipe 47 to any desired point of consumption.

The outer extremities of the cylinders 24 project beyond the flange 45 and terminate at a point intermediate the flange and the surrounding wall of the receptacle. The bottom of the receptacle between the outer wall and the flange 45 is preferably inclined toward the flange 45 and is provided with an outlet aperture to which is secured one extremity of a discharge pipe 48.

In the exemplification of the invention shown in Fig. 1 of the drawings the extremity 13 of the shaft 10 preferably projects beyond the upper edge of the receptacle 16. The receptacle 38 is provided with a suitable closure 49 having an aperture 50 adjacent the receptacle 16 and into which the upper edge of the receptacle 16 projects. The extremity of the shaft 13 is mounted in a suitable bearing 51 which is supported by means of suitable arms 52 which are secured to the closure 49 so as to hold the bearing 51 in proper position. This exemplification of the invention is particularly adapted for use in heavy machines so that the shaft 10 will be provided with a solid bearing.

In the exemplification of the invention shown in Fig. 3 the extremity 13 of the shaft is dispensed with and the receptacle 16 is supported in a similar manner by the shoulder 15 on the shaft 10 and this form of the invention is particularly adapted for use with light machines.

In use the shaft 10 is first set in motion and the liquid to be clarified is supplied to the receptacle 16 through a suitable supply pipe 53 which discharges into the receptacle 16. The liquid will pass from the receptacle 16 through the pipes 31 and be discharged into the cylinders 24 through the pipes 30. The centrifugal force set up by the rotation of the shaft 10 will cause the heavy particles or solid matters to be thrown outwardly toward the outer extremities of the cylinders 24 while the clarified liquid will work its way toward the inner ends of the cylinders and will pass out of the enlarged portions 26 through the pipes 28 and be discharged into the receptacle 46, from which it is conveyed as clear liquid through the pipe 47 to any desired point of use. The liquid may be continuously supplied through the pipe 53 to the machine until the water or liquid discharged throughthe pipes 28 becomes cloudy. At this point of the operation of the machine, the supply of liquid may be shut off and the machine then stopped, the closure 49 removed, and the closures 32 at the extremities of the cylinders also removed if the form of closure is used as shown in Fig. 1 or if the form of closure which is used is the form shown in Figs. 5 and 6, the latter may be adjusted to open the ends of the cylinders. hen the outer ends of the cylinders have been thus opened the machine may be again started by rotating the shaft 10 until the desired speed is acquired, at which time the centrifugal force generated will throw the heavy particles or accumulated matter out of the open end of the cylinders into the receptacle 38 and this sediment will accumulate between the flange 45 and the wall of the receptacle from where it may be discharged or conveyed through the pipe 48 to any desired point. I

In the exemplification of the invention thus far described the machine is of a size to be particularly adapted for use for clarifying large quantities of liquid and preferably includes four cylinders but any number of cylinders may be used, and the invention may be so constructed as to be particularly adapted for medical purposes. In "this form of the invention the machine may be constructed on a much smaller scale or a size about the size of the ones now employed in physicians oflices for separating or collecting a small amount of sediment from large quantities of urine for microscopic examination. The number of cylinders .in this character of the machine may be limited to two and the closure or cap at the outer extremity of the cylinder may be of any desired construction. For instance, a. conicalshaped closure 5 L may be employed and the inside of the cylinder and cap is preferably lined, as at 55, with some material not attacked by the urine.

The liquid may be supplied to the machine in the same manner and the same operation is proceeded with. After the heavy particles or sediment have been separated, the sedimentary matters remain adherent to the interior of the cap at. This cap may then be removed and examined microscopically, thereby rendering possible a perfect. microscopic examination of specimens which it is exceedingly ditlicult and often impossible to examine by the present methods.

The same device may be used for the concentration and microscopic examination of the sedimentary matters of milk or other fluids.

In order that the invention might be fully understood the details of the foregoing embodiment have been thus specifically dc scribed, but
