ALBERT E. IBOOKWALTEB AND MAX A. DORLAND, OF COEUR DALENE, IDAHO.
ORE-SEPARATOR.
Application filed April 3Q, 1912. 1 Serial No. 694,242.
To all whom '1' i may concern:
Be it known that we, ALBERT E. BooK-.
wAL'rnR and MAX A. 1)ORLAIID, citizens of the United States, and d .\lene, 1n the countyof Kootenai and State of Idaho, have invented certain new anduseful Improvements in Ore-Separators, of which the following is a specification.
This invention relates to certain new and useful improvements in ore separators and the object of the invention is to produce a separator which will be exceedingly efficient in use and one which may be readily manufactured and capable of wide range of use and affording ready means of adjustment. The invention consists in-thc construction and arrangement of parts shown in their preferable embodiment in the drawings forming part hereof and'as will now be more particularly described and claimed.
In the accon'ipanying drawings: Figure 1 is a vertical central longitudinal section of my invention. Fig. 2 is a vertical cross section. Fig. 3 is a perspective view of the various frames detached, in order to better show the construction.
Referring now to the details of the drawings by numerals: 1, 2, 3 and 1 represent the main frame of the machine which may be constructed in any desired manner, this frame varying accordingto the capacity of the machine and having a number of frame sections. The upper cross members 2 of the main frame are designed to support the shaft 6 from a crank pin 7 on which is operated a plunger rod 8 adapted to give the usual movement to the plunger 10. The said plunger 10 is located within the plunger compartment 12 formed by an outer Wall 14 supported by the main frame member 1 and a divisional wall 16. Nothing new is claimed in the parts so far described since the construction of the plunger compartment is similar to those now in common use. The screen compartments, as illustrated in Fig. 2, are alongside of the plunger compartments and are each formed between the aforesaid divisional wall 16 and an outer wall 17 supported by the vertical frame member 3. As is common in ordinary forms of separators, the plunger compartmentand the screen compartment both open into hoppers such as illustrated at 18 in Figs. 1 and 2, the bottom of each hopper, if the separator is to be used for working gold, delivering the material to a glass jar as 20.
Specification of Letters Patent.
residents of Coeur' Patented Apr. 8, 1913.
Said hoppers 18 each have a delivery tube 19 preferably of metal in each of which is a valve 21. In working with coarser and more plentiful metals, the jars 20 will not be used but the material may be delivered through the tube in the apex of the hopper lnto any suitable receiver.
Contained within each of the screen compartments are the following devices: A deflee-tor tray is located at the bottom of the screen compartment, supported by strips or cleats 24. As illustrated in Fig. 3 this deflector tray comprises a rectangular frame 26 having a series of deflectors 28 supported thereby, the deflectors having trunnions 3O resting in recesses formed in the upper part of the frame 26. All of the deflectors 28 are connected together by a common connecting strip 32, and to one of the journals of one of the deflectors is connected an operating lever 34; the construction being such 7 that all the deflectors may be simultaneously moved Whenever the operator moves the aforesaid lever 34. The top of each deflector is rounded and the tops of all the deflectors are flush with the top of the frame in order to form a support for the screen located above them. This screen, designated 40, is connected to a screen frame 42, the screen frame resting upon the deflector tray 26, the screening itself resting upon the upper rounded surfaces of the deflectors 28. Owing to the fact that the tops of the deflectors are rounded they may be moved at any ang e desired and still afford a firm sup port for the screen 42 resting thereupon. One side of'the screen frame 40 has projections 44 thereon which provide a space between the screen frame and the wall 17 for the passage of the operating lever 34. Upon the screen 40 is one or more layers of balls 41.
Located above the screen frame 42 is an being connected together by means of a connecting strip 56 so that the riffles move in unison. An operating lever 58 15 provided whereby all of said riflles may be moved on their pivots, in either direction, to the extent desired. The first ritfle frame 50 is provided with an inlet 60 near the bottom of the receiving end and an outlet 62 near the upper part of the discharge end, and when the three frames 26, 42 and 50 are inserted in their screen compartment, as indicated in Fig. 1', the aforesaid. receiving aperture 60 of the first riflle frame will be in line with the feed .inlet 64 and the discharge aperture 62 will be in line with an aperture 66 formed in the divisional wall 68 and also in line with asimilar opening leading into the riflie frame of the next screen compartment.
Cooperating with the riflles 54 in the riflie frame 50 are damboards 70 and 72, these boards being designed to fit into slots 74 in the sides of the riflie frame 50 as illuswith the bed of balls.
trated in Figs. 1 and 2. Should the afipparatus be used without the upper ri e frame 50, the dam boards 72 may be supported in slots 76 in the divisional wall 16 and the outer wal1 17 as illustrated in full lines in Fig. 1 and in dotted lines in Fig. 2.
The devices arranged in each of the screen compartments are duplicated in each compartment except that only the first compartment is provided with a feed inlet 64 and only the last. compartment is provided with an outlet 78 as illustrated in Fig. 1.
It is believed that the operation of my invention will be obvious to those skilled in the art yet it-may be well to state that the plunger 10 of the jig is given movement by means of the crank pin 7 which imparts motion to the material in the screen compartment, in the usual manner, so that as the plunger moves up and down the water is forced from the opposite side of the partition 16, thus causing a special action withrelation to the various balls on the screen 40, the balls of different sizes acting as an artificial bed and having a specific action in separating ore from slimes or finer ground rock or sand. The balls, arranged upon the fine screen, create a suction as the water is drawn downward which is a great service in separating as most of the fine metalsxseek a vacuum or suction. The riffle tray placed above the screen tray and balls s designed to retard the progress of stock through the machine and instead of permitting a free passage of stock, the riflles tend to force the fine particles of ore down into the water in contact The riflies are adjustable according to need-so as-to increase or decrea'se the action as may be desired. The purpose of the deflectors under the screen is two-fold, one to support the screen, however much the deflectors may be turned,
and the other to deflect the action of the water, for, when the plunger goes down, the water is-forced up on the opposite side of the partition and gives backward or forward motion as desired to' retard or hasten the passage of stock through the apparatus. The dam boards above the riliie frame are designed to co-act with the rifiles and further obstruct the passage of stock and cause it to be forced down into the water so that the finer particles cannot float away and be lost. These boards being placed between the ritlics give any water or slime that may pass over the top of the riflles an u and down motion, mixing it thoroughly in the water and tending to increase the contact of the stock with the bed of balls below the riflies. We call attention to the fact that the feed inlet 64 is so located that the stock is fed below the water line and so that its passage is obstructed by the aforesaid riflles and also so that the dam boards will act as just described.
In order to prevent the balls on the screen 40 from passing down into the base of the machine in the event of breakage or accident to the said screen 40, we prefer to employ a screen 80 located under the deflector tray as indicated in Fig. 2. This screen would be of a size corresponding to the size of the ballsso that should an accident happen to the ball screen 40, the balls would be caught by the screen 80 and prevented from going down into the bottom of the hopper 18. The screen 80 is supported by the lower end of the divisional wall 16 and by one side of the hop er 18 and an opening 82 is provided in t e wall of the hopper 18, closed by a removable plug 84. If preferred this hole may be located so that the balls. in the event of breakage of the screen 40, will gravitate to the hole 82, when they can be removed by taking out the plug 84 in a manner well understood. The bottom of the partition wall 16 may have a series of openings 86 to offset the resistance of the lower screen to the upward action of the water.
It is obvious that changes and modifications may be made and reference should therefore be made to the appended claims in order to determine the scope of the invention.
