' Specicationofletters Patent. l Patented Apt'. 29, I9I3. Application flied November` 9, 1912, Serial No. 730,369. i
In certain localities, river-sand contains a certain amount of foreign material, such as coal dust and `ore of diierent kinds, and the principal object of this invention is to separate these foreign materials from the sand, to reclaim the ore, especially the gold-ore, but mainly to clean the sand, so that the coal dust or other staining materials will not discolor the cement -Work in which the sand is used. This and other objects hereinafter set forth are attained by the means illustrated in the accompanying drawings, in
which:-. .i
Figure 1 is an elevation of a pump boat showing niy improved apparatus mounted 2 is a plan view of the upper portionv of the apparatus only.y Fig. 3 is a cross-section on the line 3-3, of Fig. 2.
Similar reference numerals in all of the figures of the drawings designate like parts.
The apparatus comprises a main trough 4, closed at its rear end as at 5, and provided with apocket 6 onits underside. In the bottom of the trough 4 adjacent said closed rear end is.formed an aperture 7 which cornmunicates with a discharge pipe 8, preferably of' a centrifugal suction pump 9, which is provided with the y usual suction pipe 10` having a nozzle ll'at its lower end, through ythe bottom of the stream.
which is sucked the sand-and gravel from The upper end of pocket 6 communicates with trough 4 and in the bottom of said pocket is tapped a discharge pipe 12 of a suction pump 13, which is provided with a suction pipe 14 adapted to draw water from adjacent the surface of the stream. In one side wall of the pocket isprovided an o-utlet aperture 15 which communicates with an inclined trough 16 for a purpose hereinafter described, and on a level with the lower side oi: the aperture 15 and extending across said i pocket, is al located thetrough, is a communicates .with
ing therefrom and adapted to engage screen 17, preferably a perforated plate. A. removable cover 18 is 'provided forfanv aperture 19 in one of the side walls of said pocket, said cover being provided with'a'suitable packing to-prevent leakage. v Covering thetop oisaid pocket 6, Vis a Aline screen 20 longitudinally 'exten in'g wires only, Awhereby coarse materialssuch Vas gravel, etc., will freelypass '-thereover. One' edge j of'` the preferably formed solid preferably` formed of screen 17 ladjacent theoutlet vaperture 15 is to-provide a shelf toallow the pure sand to Settle thereon and i be forced. into the sand trough 16.
In'the bottom of thetrough 4 and between.
the pocket -6 and the outlet end of said discharge 'opening 21, which a gravel discharge trough 22, and said opening Qlis alsov provided with a screen 23 preferably formed like screen Q20 butgof a coarser mesh to allow gravel to pass therethrough. It will be observed th'at'the upperend of pipe 12 extends above the bottom of pocket 6 thereby form- .jin at the bottom of said pocket and around said` pipe a receptacle' to receive material heavier than the sand, such as gold ore, etc. .r To i.e'gulatethe` pressure of the vWater in pocket 6 whichjis discharged therein from. 'the `pump waste outlet, a pipe'is tapped into the side: jiofsaidpc'ketfblow the screen'l and p ro-V iand atthe same time provide a vided with Vsiviveled section 25 which extends ulwardly andforwardly. from said pipe. 'T e adjustment ofsectionQ to and from a lvertical position will regulate the pressure of jwaterinisaidipocket 6.x To facilitate theY 25, a suitable means is adjustment' of section securing ysaid section provided thereon for' extendinV position and a lip 28 the to secure it upperedge of trough 4.)
In operation, ,both pumps are umping, one' delivering sand, gravel, etc., romthebed of the trough 4,4 and 'the' other delivering water from the.top of the stream to the pocket 6. The sand and other material flow toward the discharge end of trough 4,
the heavier Isubstances settling on the botand when screen 20 4is reached, the sand particles pass through said The gravel contoma and tine heavy screen into the pocket 6..
tinues on and passes through 'the screen 23 Astarted j of the streamto the rear end.
,at in its adjusted Qos1tions,sai d,means embodyvving a sliding collar QGhavin'g a set-screw`27 ico i iet and discharges into the trough 22, and the lighter materials pass along the trough 4 and ar`e discharged therefrom, usually back into the stream. The sand and tine heavier particles which fall into pocket 6 are .thoroughly stirred and agitated by the force of water in said pocket supplied from the pump 13 and according to the pressure regulated by the section 25, the heavy particles such as ore, will drop onto and through the screen 17 into the bottom of the pocket. The sand being lighter than the ore, will be held in suspension above the screen 17 and gradually settle on the solid edge of said screen and pass out into the trough 16. Other foreign material lighter than Vthe sand will be forced upward out of the pocket and carried along with the waste to the discharge end of the trough 4. In this manner clean sand and gravel are separated from the' waste material and the ore accumulated to itself.
It will be understood that' the several troughs, viz., sand, gravel, and Waste troughs, can be extended as desired to de-y liver to any selected place whether in a boat or upon land.
If desired, the end of the suction pipe 14 can be provided with a nozzle or strainer to prevent debris from enterin said pipe.
The force of the water owin upward through the screen 17 is stronger t an when passing through the screen 20 owing to the discharge 15 above the said screen 17, and for this reason, the lighter sand will pass through said discharge 15, the heavier sand and ore will pass through screen 17 and settle'on the bottom of the pocket, and thev very light materials will pass over the.mouth of the pocket without entering, owing tothe upward How of the water `from the pocket.
.Having tlius fully described the invention what is claimed is:
1. In an apparatus f'the character described, a trough, means for delivering material to said trough, a pocket in said trough,
scribed, a trough, means for delivering material to said trough, a pocket in said trough,
a sand discharge from the side of said pocket, a screen in said pocket below said lsand discharge, a gravel discharge from said trough intermediate said pocket and the outlet of said trough, screens of successively increasing size of apertures vover said pocket and gravel discharge respectively, and means for forcing water in said pocket below the screen therein to cause the water to ilow through said screen, said sand discharge, andinto said trough to separate the lighter from the heavier materials.
8. In an apparatus of the character deyscribed, a trough, means for delivering material to said trough, a pocket in said trough, a sand discharge from the side of said pocket, a gravel discharge from said trough intermediate said pocket and the outlet of said trough, screens of successively increasing size 'of apertures over said pocket and gravel discharge respectively, means for forcing water in said lpocket to cause it to flow through said sand discharge and into said trough to separate the li hter from the'.
heavier materials in said poc et, and means communicating with said pocket for regulating the pressure vof Water' therein.
In testimon whereof I aix my signature in presence o two witnesses.
