To all who/'m it may concern:l

Beit known that l, HENRY M. GOODMAN, a citizen of the United States, residing` at Louisville, in the county of Jefferson, in the State of Kentucky, have invented certain.

new and useful Improvements in CcntrifugalV tion of sand and. silicous matter .from large amounts of Water, etc., and the primary ohject of the invention is to provide improved means for delivering the material to be separated into the machine, and improved. means for permitting the escape of the liquid from which. the material has been separated.

A further object is to provide improved means for discharging the material from the machine without Ainterrupting the motion thereof. i

A further object is to provide an improved discharge gate or valve for closing the separator cylinder and which is adapted to be closed and held closed by the action of the 'air on-a portion of the gate or valve during the motion of the machine.

A further object is to provide improved fluid controlled mechanism for actuating thegate or valve to permit the discharge of the material. y

A further object is to provide an improved support for receiving the discharged material and an improved shield for directing the material onto the support when it leaves. the cylinder..

A further object is to provide an improved machine of this character which will be simple, durable and cheap mconstruction, and

effective and efficient in operation.

To the attainment of these ends ,and the I accomplishment of othernew, and useful obr the invention, and in Which- Figure 1 'is a longitudinal sectional view of an improved mafchineof this character con st ructed in accordance with the principles of this invention.. Fig. 2 is a horizontal sectional view on line 2-2 of Fig. 1. Fig. 3 1s a detail elevation of the gate'or valve for closmg the end of the cylinder and showing the' same in dotted lines in an open position. Fig. L1 is a detail sectional view of the operating means for the gate or valve.

Referring more particularly to the draw* ings and in this exempliiication of the invention, the numeral 10 designates a suitable supporting base, to which is secured a vertical tubular member or pipe 11,4 which is closed at its upper end and is provided with an aperture 12 extending through the side thereof adjacent the closed end. rl`he base of this member or pipey 11 is preferably enlarged as at13 and passing through the supN porting base '10 is a supply pipe 14, which is secured t'o the member or pipe 11 in such a manner as to communicate with the opening Surrounding the tubular member 0r pipe 11 preferably adjacent the' base thereof is a closed chamber 15, the bottom' of which is preferably provided with an enlarged por tion-16 adapted to rest upon the'enlarge- `pipe or. member 11 and is held in position by a suitable bushing 19 to form a liquidV tight joint. I I

Secured-to thechambers 15 and 17 are cylinders 2() preferably two in number;

rwhich are arranged diametrically opposite each other and communicate with thespace formed betweenl the vchambers 15 and 17. These cylinders 20 ma be held in position in any desired or suitab e manner,- preferably by means 'of screws or bolts 21,\which` pass through suitable flanged portions on the cylinders 20'and through the Walls of theY resective chambers-15 and 17.

. he chamber 17 is provided with apertures or openings in the bottom thereof and `leading from' said apertures or openings are pipes or tubular members 22- which extend into-the space between the lchambers 15 and 17 and `the free ends are preferably bent 4at a right angle to extend into 'the respective cylinders 2O so as .to discharge preferably at the-diametric centers thereof and terminatev just' beyond the adjacent ends of the cylinders.

Located within the cylinders 20 and secured to the walls thereof are shields 23 which surround the end of the tubular members 22 and said shields are preferably constructed of any suitable reticulated material, such as wire-gauze or the like.

The top of the chamber' 15 is provided with suitable vapertures or openings 24 located adjacent each of the cylinders 20 and said cylinders are provided with a projecting lip or portion 25, which extend into the apertures or openings 24 so as to direct f theliquid from the cylinder 20 into the chamber 15. Surrounding the enlarged portion 13 of the` tubular member orpi pe 11 and pref-. erably supported by the base 10 is a chamberor catch basin 2G, leading from the bot-v tom of which is a dischargeor outlet pipe-27.

i The chamber 15 is provided with apertures 28 in the bottom thereof which communicate with the chamber or catch basin 26'. The cylinders 2() are preferably arranged horizontally and the free extremities thereof arc open. Any suitable means may be provided for closing the open ends of the cylinders.

l A suitable and ellicient means for accomplishing this purpose comprises a gate or valve 29, whichv is pivotally supported by' one extremity of a suitable shaft or axle 3l), which latter is journaled in suitable bearings 31'pn the cylinder 20. Any suitable means maybe provided for securing the gate or valve 29-to the extremity of the shaft or axle. 30, such as a screw or bolt 32 or the like. The other end of the shaft or axle is pro- 'vided with a crank arm 33, which is prefer- ,ably located adjacent the chamber 17` Supported in any desired or suitable manner adjacent the crank arms 33 are cylinders 34 arranged within which are suitable piston heads 35 connected. to piston rods 36, which extend through the cylinders 34 and are connected to the respective Acrank arms 33,l Each of the cylinders 34 are provided with exhaust openings 37 topermit the piston heads to move downwardly within the cylinders and when said piston heads are so moved, the Apiston rods 36 will move theV crank arms to rock the shaft or axles 3() and move the gates or valves 29 about their points oll pivotal support to open the free ends of the cylimlers 2.V

Secured to the top of thc cylinder 17 is a hollow shaft 38 which is preferably closed at one end as at 39 and secured to said shaft is. a belt or pulley wheel 40. The upper end of the shaft is journaled in a suitable bearing in a suitable plate or member 41, which is supported and held in posit-ion by means of spaced standards 42, which are secured to the base 10 and surround the cylinders 20 and chambers 15 and 17 and arms 43, which rise from the tops of the supports or stan'dards 42 and upon which the plate or member valve 49.

Leading from and communicating with the tubular shaft 38 -are pipes or tubular members 50, which communicate with the cylinders 34 preferably through the tops thereof, so that when the throttle 48 is opened to permit the fluid to pass into the chest 46 through thepipe 47, it will pass through the tubular shaft.38 andv pipes 50 into the cylinders 34 and move the pistons downwardly to rock the shafts 30 and open the gates or valves 29. Each of the gates or valves 29 is provided with .projecting arms 51, 52, preferably arranged at right angles to each other, as shown more clearly 1n Fig. 3 of the drawings. These arms arev each provided with an enlarged free 'eX- tremity 53 for a purpose to be setvforth` Se- 'cured to each of the cylinders 20 is a lip or projection 54 which is preferably arranged to one side of the center thereof and serves to hold the Vvalves or gates 29m a closed position.

ards 42 and preferablybelow thev free ends preferably spaced therefrom and surround'-` ing the uprights or standards 42 is a shield 5G and against which the material will be discharged when the gates or valves 29 are open, so that the material will be directed upon the supporting shelf 55.

Assuming the parts to bein theposition as shown in Fig. 1, the operation will be as follows: The material to be separated is'fed into the chamber 17 through the pipe 14 in any desired orsuitable manner, preferably by means of a pump (notshowl'r). Zhen this pump is operated, the material will be forced .into the chamber 17 through the pipe 1 4,

tubular member or pipe '11, and through the opening 12. From the chamber 17 .the material, together with the liquid; will pass through the tubular members or pipes 22 and be discharged into the cylinders 20. Motion being imparted to the shaft 38 through the medium of the pulley Wheel 40, the chambers 15 and 17, together with the cylinders 20,' will be rotated about the tubular member or pipe 1], the enlarged portion 16 of the chamber 15 resting upon theenlargement I13 for a bearing. The rapid rotation ofthe cylinders 2() will cause the material which 'is discharged therein throufrh the tubular members or pipes 22 rto be thrown Arranged between the 'uprights or standsuitablereceptacle 57.

'l centrifugal force outwardly towards the and ^`tliereol2 or against the gates or valves The liquid Which enters the cylinders 2l) with the uiaterial will 'flow towards the pipe or member l1 and pass through the shields or guards 23 into thechamber 15 thrmlgh the apertures 24 and from the chamber through theapertures 28 into the reoep tacle or trap 26 from Where it conducted by means olf' the discharge pipe 27 to a,

The material will also be held in the cylinders by means of the guardsor shield's23. This operation will be continued until the cylinders 20 are sul stan tially Vlilled with the material or until the liquid, AWillich is discharged through the free end of the pipe 2,7 into the receptacle 57, be-

comes thick, from which the operator Will lrnow ceases to lloW the operator then opens the throttle 48, Which permits the lluid to enter the chamber' 46- through the pipe 47 and from the chamber it will pass through the tubular shaft 38 and pipes 50 into the cylin ders 34 to-moye the pistons 35 and rock the shafts 3U to open the gates or valves 29,

ifi/'hen the gates orvalves 29 are thus openedand held in their open position by the pressure of the iluid acting upon the piston/heads 35, the material in the cylinders Will be thrown out 'by centrifugal lorce against the shield 5o, which latter will deilect the same onto the shelf or support from which it may be collected into any desired receptacle. Alfter the cylinders'l() have been'emptied of the separated material, thenexhaust valve 49 may be opened to permit the escape of the fluid which has entered the cylinders 34. As the fluid escapes through the exhaust i 'valve-49, the valves or gates 29 Will-be closed by thefaction of the air against the enlarged. portions 53 of the arms 51, 52in the followin@ manner. When the valve 'or gates are held open they will assume the position' shown in dotted lines in Fig. 3 of the draws ings so thatf the enlargement 53 of thearm 52 will be presented to the air as the machinel revolves. The resistance formed by the air will cause the gate or valve to be moved about its pbint of pivotal support until the enlargement 53 on the arm 5l is presented to the airfas shown in full lines iin-Fig.A 3 of' the drawings. lrVhen the arm 5l is in the position shown in full lines in Fig 3,. the edge that the cylinders are substantiallys y of the gate or valve will engage the projecting li p or stop 54 and hold the gate or valve 29 against further movement. T he action of the air upon the enlargement -53 of the arm 5l will holdthe gates or valves closed during the rotation of the machine and until thel fluid'is forced into the cylinders 34 to operate the pistons 35 and move the valves or gates 29 against the resistance of the air. Vhile there is shown and described in this exempliiication only two cylinders for sepa* rating the material, it is obvious that any number of cylinders may be provided and it will also be understood that the chambers 15 and l7 instead of being constructed inde-' pendently of each other and secured to the' .cylinders 20, they may be constructed integrally.
