Specification of Letters Patent.
Patented Mar. 2,
Application filed February 8, 1913. Serial No. 74.7109? To all whom it may concern:
Be it known that I, ARTHUR E. Cosrnn, a citizen of the United States, and a resident of Salt Lake City, in the county of Salt Lake and State of Utah, have made certain new and useful Improvements in Vibratory Screening and Sizing Devices, of which the following is a specification.
My invention relates to improvements in screening and sizing devices for use in treatment of ores andother similar substances, and it consists in the combinations, constructions and arrangements herein described and claimed.
An object of my invention is to provide a device for economically treating ores in which the over-size is separated from the fine material, the latter being fed to an amalgamator, or device for final treatment of material in the form of a thickened pulp.
A further object of my invention is to provide a vibratory screen in a launder operated by the water which passes through the launder.
A further object of my invention is to provide novel means for disposing of the over-size.
A further object is to provide novel means for flushing the screens.
Other objects and advantages will appear in the following specification, and the novel features of the device will be particularly pointed out in the appended claims.
My invention is illustrated in the accompanying drawings forming part of this specification in which i Figure 1 is a side viewoi the device as a whole, Fig. 2 is an enlarged sectional view on the line 22 of 1!, Fig. 3 is a detail view of the screen holding and vibrating mechanism, Fig. l is a pliin view of the deice, Fig. 5 is a diagrammatic view of a modified form of the device, Fig. 6 is a section through one of the separating tanks,
and Fig. 7 is a plan view of a portion of the apparatus shown in Fig. 5.
In carrying out my invention 1 provide a launder '1 having a sizing screen disposed therein. Below the sizing screen is a tank 3. At the end of the launder 1 is a grizzly l which communicates with a discharge chute 5, leading to the dump or to the re-- crushing machinery (not shown). An auxiliary pipoor fiume 6 discharges into the e latter, as ill be seen from Fig. 1, is of cons1derable length. This launder provided with a screen 9, which may be oi a suitable material, that is, a punched or slotted plate or woven wire screen. This screen is of any suitable mesh for the work to be done and is supported at intervals by devices such as that shown in 3. it will be observed that at intervals along the launder 8 I have provided U-shaped metal cross members 10 secured to the bottom of the launder. A guide rod 11 is secured to the cross member 10 by means of nuts 12. A spring 13 surrounds the guide rod 11 and bears at one end on the cross member 10 and at the other on a washer 14. The screen 9 is held between the washer Hand a movable post or sleeve 15 which surrounds the guide rod vl1 and between whose base and the Washer 1d the screen 9 is clamped by means of the bolts 16. It will thus be seen that the screen is cushioned upon the spring 13. As will be seen from Fig. 2 there are a plurality of these screen supports in alinement.
In the figure I have shown two, but obviously there may be more or less, depending upon the size of the screen.
Rotatably carried by the walls of the launder directly above the screen supports are the transverse shafts 17 upon which are mounted cam wheels 18, such as that shown in Fig. 3, arranged to engage the upper end of the post or sleeve 15 so as to force the latter downwardly against the tension of the spring 13. One of these shafts 17 bears one or more wheels 19 which are driven by the force of the water passing down the launder. These wheels are connected by pulleys and belts 20 so as to provide power for operating the cam \VllEi-lS 18 on the shaft 17,
therobycausing the vibration ofthe screen 9.
D sposed beneath the launder 8 and the screen 9 is a series of tanks 21 of conical shape at each of whose bottoms is a pipe 22 which is provided with a valve 23. A pipe 24 connects with the pipe 22 between the valve 23 and the bottom of the tank 21 and is provided with a valve 25. In Fig. 1 I.

A. po 1" this screen is disposed in the over-size chute 29. A feed launder has one end disposedbenea'L-h the screen 28 the other end being flared out- Wardl as shown in Fig. l, and being disposed above one end of the distributing box and classifier 26. The latter is provided with a discharge chute 31 which terminates in such a position as to permit the water which is discharged to drive a wheel 32. The latter is provided with a belt 33 run.-

From the foregoing description of the various parts of the device the operation thereof may be readily understood. The
v launder 1 receives the ore or other material from the crusher and screens out the finer material from the over-size which then pass .down the grizzly 4 into the over-size chute 5, being carried off by means of the water received from the auxiliary chute 6 to the dump. The water now passes through the grizzly and carries with it any suspended matter into the chute 7 which empties into the launder 8. The fine material which settles in the tank 3 may be fed into the launder 8 by means of the auxiliary pipe 22*, the flow being controlled by "the valve 22 The pipe is a water pipe which will permit the flushing of the tai 3 from below and also the cleaning of *r screen 2 when the valve 22 'is closed. material pz'issing through the launder 8 screened by the vibrat-cry motion imparted to the screen 9 in the manner already explained. The line material settles in the tanks 21 and from there may be passed directly into the dis-- tributing box and classifier by means of the pipes 22. tank and the screen above it may be flushed by water which passes through the pipe 24, the latter pipe being controlled by the valve 25 as shown in Fig. This prevents any clogging of the en 9. The water which passes down un'deii' operates the Wheel or hydraulic 9, which furnishes power for ing the cams.

The water leaving the wheel 32 passes out of the discharge chute 40, thus washing the over-size out'upon the j dump. In Flg'. 5 I have shown' 'a modified" arrangement in wh ch the launder 4:1 is' provided with a series of screens 42, 43; 44, 45, etc, (see Fig. 7) of different mesh; the finer screen being locatednear the chute 46 which leads from the ci usherflil Beneath each i screen is a tank dissimilar to the tanks 21, shown in Fig. 1. These tanksare provided with means for draining them and, for fiushing them similar to the means already described. At the end of the laundereda I chute 4:9 for the over size which may be pumped or elevated by means-of an elevator i 50 through the pipe 51' back again to the crusher, or the chute 49 may lead directly to the dump. In the mod fied form'of the device the arrangement or the difi'erent size screens provides for the sizing of the ores i or other products which it screen or classify i By the use of the vihratory screen defined screen size material will be had. The valves which lead from the bottoms of the tanks such as 21 and 418 may be so regulated is I desired to as to furnish thickened pulp. The arrangemo'nt described greatly reduces the wear on/Jhe screens Itfurnishes an elfi cient device for separating out or classify ing the screened material of difi'erent size. The provision of the wheels 'for operating the cam devices which vibrate the screen re-' 1 duces the power necessary to operate the device. Of course, these camsmay be operated by other power, not shown, without departing from the spirit of the invention;
The water escaping from the end of the power for operating: the amalgamator or other" similar dcvice; This water then passes onto the over-size chute and aids in oil the oversize. 1
It will thus be seen that the device described provides an economical way of eat g or other similar material. err toe'devicc is easily cleaned or flushed so that there is no danger of the screens clogging up. The device requires little attention when once installed and the parts are easily accessible for repair or replacement if any of them should wear out.
I claim l. The combination with a launder, of a screen arranged therein, a cushion supporting device for said screen comprising an upright guide member arranged to extend through the screen, means for supporting said upright guide member, a movable sleeve arranged to fit over said guide member, said screen being secured to said sleeve,
and a wring disposed between said screen tionar screen disposed in said oversize chute, a return feed launder having one end disposed below said stationary screen, and a receptacle for receiving the water from said return feed launder.
