Specification of Letters Patent.

3 Application filed May 7,1913. :Berial No. 768,010. r
To'all whom it may concern Be it known that I HARRY P. Molnmn, a-citizen of the United States, and a resident of: Colorado Springs, in the county of El Paso and State of Colorado, of the United States of America, have made a new and-use ful Improvement in Concentrators, of which My invention re ates to improvements i a device for concentrating ores, and it con sists in the combinations, constructionsand arrangements herein described and claimed.
An. object of my invention is to provide a device for concentrating ores which is cheap to manufacture and in which economy of power is effected.
' A further object of my invention is toprrr vide a device in which a great economy of nature.
water-is effected, and having a large capacity in proportion to its size. w
- The further'object of'my inventionis to provide a device which 1s of a portable- Other objects of the invention will appear inthe following specification and the novel. features of the device will. be particularly set out in the appending claim.
My invention is illustratedin the accompanying drawings forming a part of this application in w ich igure 1 is a section through the device.
Fi 2 is a plan view of the device. Fig. 3 is a detail view showing a portion ofthe face of the concentrator belt. Fig. 4 is a view similar to Fig. 3, showing a modified form of belt. Fig. 5 is a view similarto Fi s. 3 and 4 of another modified form of clt. Fig. 6 is an enlarged section along the line 66 of Fig. 3. Fig. 7 is an enlarged section along the line 77 of Fig. 4. Fig. 8 is an enlarged section along the line 8-8 of Fig. 5, and Fig. 9 is a detail view showing the means for vibrating the belt carrier.
In carrying out my invention I provide a tank 1 of any suitable construction, having bearings 2 upon which is mounted a main drivin shaft 3. One end of the driving shaft 1s provided with a driving pulley 4. Mounted upon the shaft 4is a yoke 5, a friction wheel 6 and an eccentric 7 (see Fig. 2). Carried by the yoke 5 is a shaft'8 bearing a friction disk 9 which is arranged to be engaged by the friction wheel 6. The shaft 8 is really in two sections being provided with a universal joint 8. This shaft, as will be seen from Fig. 1, is normally incl ned and toward its lower end is provided with a worm 9. The shaft 8 has a slot 8" which ernnts the. worm nally o the shaft.
Mounted upon supports, such as those to slide longitudishown at 10, within the tank, is a. belt carrier or frame 11. I This frame bears at one end a gear 12 arranged to be engaged b the worm 9. The gear 1s connected with a rum 13, (see Fig. 1) over which an endless belt 14 (see F1g.2) 1s arranged to travel. The
opposite end of the carrier 11 is provided with a similar drum or roller 13* for sup porting the belt. The frame 11 is arranged to be vibrated in a direction at right angles to the travel of the belt by means of a device ,which is illustrated in Figs. 1 and 9. The
eccentricz? is connected by means of a rod 15 w1th a toggle omt 16, one end of which is fastened to the sideof the tank 1, the
other end being fastened to one of the trunnions 17 of the belt carrier.
At the lower end of the belt carrier frame is a trough 18 for receiving the tailings,
while directly underneath the roller 13,
shown in dotted lines in Figs. 1 and 2, is a of a portion of a pulley 20 operated by a belt 21 which passes over a pulley on the drive shaft 3". A Tchute or spout 22 extends downwardly toward the belt and terminates just above the latter as shown in Fig. 1.
nu-The belt 14 is preferably p rovidcd with bafiles or rifiles. I may use a belt like that shown in Fig. 3 or one like that shown in Fig. 4 or Fig. 5. In Fig. 3 the belt 14 is provided with a series of curved riflles 14. The belt shown in Fig. 4 is provided with a series of central rifiles 14 with corrugations 14 formed in the face of the belt, these corrugations being disposed at an angle of approximately 10 and sloping from the sides of the belt toward the central row of rifiles.
In Fig. 5 I have shown a belt having a row of rifiies 14' at one edge with corrugations 14 formed in the belt and sloping from the opposite edge toward the ritiles 14".
From the foregoing description of the various parts of the device the operation thereof may be readily understood. The tank 1 is filled with water up to the line w a; shown in Fig. 1. The ore is fed in through the hopper 19 and passes down through the chute 22 upon the belt. The revolution of the shaft 3 drives the disk 9 through the medium of the friction wheel 6. This turns the shaft 8 which through the medium of the worse 9 and gear 12 drives the upper drum 13 thereby causing the travel of the belt 14 over the drums 13 and 13*. llhe ore falling will be apparent that the transverse moveon the belt is carried upwardly. The motion imparted. to the carrier 11 by the toggle joint arrangement described tends to agitate the. ore so that the lighter particles pass down the inclined belt and are deposited in the trough 18. from which they may be deposited in the bottom of the tank. The heavier and more valuable portions of the ore are carried upwardly and are damped into the receptacle 1" from which they may be removed in any suitable manner.
The belt carrier may be tilted at an. angle greater orless than that shown, the angle depending upon the ore to be treated. lin
order to. accommodate itself to. the position of the gear wheel 12 carried at the end of the carrier ll, the shaft 8 is slotted at 8 as stated before so. that the worm wheel 9 may gear, means for imparting a vibratory move -ment to. the belt carrier at right angles to slide longitudinally thereof. 'lhe universal joint 8" permits the motion to be transmitted to the lower portion of the shaft 8? even. though the upper part may not be. in exact alinement.
When the form of belt shown. in. Fig. 3- is used the ore is fed the full width of the belt. In the form shown in Fig. l the ore is fed on the outer edge of each side, while in form. shown in. Fig. 5. the ore. is fed on the. edge opposite the curved rifles.
it will be observed that the operation of concentrating the ore is carried out entirely under water, the ore being fed at least two. feet below the surface of the water directly upon the surface of the belt, thereby eliminating slime. throughout the tank. 'lzhe separation under water is effected by the bouyancy of the lighter particles and the heavier weight of the more valuable portions. The a itation of the belt carrier permits the lig ter portions to pass downwardly while the heavier portions are caught by the riflles and are carried upwardly.
From the construction above described, it
ment of the belt carrier is such as to maintain the worlring part of the belt t. 6., that art upon which the ore is fed, in a Plane parallel with itself. Unless this is. done here is danger of the heavier particles be ing thrown over the rifiles and passin down the belt instead of being carried para llel. l have found that it is necessary to impart a vibratory movement of the belt in its own lane in. order to successfully accomplish a I satisfactory separation.
I claim: lin a device for concentrating ores, a. belt carrier, an endless belt for said carrier,
means for driving said endless belt, said.
means'comprising a drum, a gear carried by the drum, a worm arranged to engage said I the direction of the travel of the belt and in fixed and the 0 her end secured to one of said trunnions, and means for operating the toggle joint.
