ABEL G-UIONNEAU, OF DENVER, COLORADO.

ORE-CONCENTRATOR.

Specification of Letters Patent.

Patented YOct. 1, 1907.

Application filed April 29, 1907. Serial No. 370,835.

To all 'whom it may concern:

Be it known that I, ABEL GUIONNEAU, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented new and useful Improvements in Ore-Concentrators, of which the following is a specification.

This invention relates to ore concentrators, the object of the invention beingl to provide an effective apparatus of this character for quickly concentrating ores of different kinds supplied thereto. i

A concentrator involving v my invention possesses other advantageous features which, with the foregoing, will be fully treated in the following description of that form of embodiment of the apparatus which I have selected for illustration in the accompanying drawings forming part of this specification. The novelty of the invention will be covered in the claims succeeding said description.

Referring to said drawings: Figure l is a top plan view of a concentrator involving my invention, with a portion of the belt broken away. Fig. 2 is a rear elevation of the concentrator with the head motion removed. Fig. 3 is a sectional side elevation of the same, the belt being in section. Fig. 4 is a detail view in front elevation of the belt. Fig. 5 is a top plan view of the same, and Fig'. G -is a'sectional detail of said belt. Figs. 7 and 8 are detail views of the adjusting gear.

Like characters refer to like parts throughout the several hgures.

The apparatus includes in its make-up a suitable bed or foundation and this may be of any desirable character, the same comprising in the present instance the suitably connected duplicate sills 2 to the opposite ends of which are fastened in some convenient way the flexible links or straps 3 of which there are four illustrated in the drawings. The upper ends of these links are connected in some desirable manner to the connected frame members 4 which directly sustain the concentrating mechanism and which are simultaneously given a vibratory movement in a direction transverse of the endless belt hereinafter described for the purpose of stratifying the pulp on said belt. The links 3 may be of wood or metal or a composition of these materials. The frame members 4 are separated horizontally from the sills 2, as shown clearly in Fig. 2.

A roller or drum is shown at 5, andthe shaft 6 of said roller is supported by suitable bearings upon the frame members or beams 4, said shaft 6 having fixed thereto at one end, as shown in Fig. 1, the disk 7 having on its outer face a lug as 8, the function of which will be hereinafter described.` This shaft G serves as a pivot or center for the beams 9, said beams 9 having at the end thereof opposite the shaft 6 bearings for the drum or roller 10 which is complemental to the drum 5. An endless belt as 1l travels around these two drums. The belt 11, or at least the working portion thereof, is

inclined, and, in the present case, the upper run of said belt constitutes the working portion thereof. The inclined belt may be made of any suitable material. I prefer, however, to make it of rubber and, when of rubber, it will have molded thereon the transversely disposed riifles 12 which extend from the back of the belt or that part at the right in Fig. 3, to the front thereof. When the belt is of rubber I preferto make the riffles 12 of rubber, the said rifiies being of progressively decreasing thickness or depth from the back of the belt to the front thereof. It is not essential, of course, that these parts be of rubber, as will be evident from what I have stated. Along the back of the belt I form a fiange as 13 which prevents the escape of pulp and wash water fromthe belt, the fiange extending the complete length of said belt, as shown clearly in Fig. 4. I have shown by arrows in Figs. 1 and 2 the direction of movement of the belt, and any suitable means may be provided for operating the belt. I will hereinafter briefly describe the means shown for this purpose. The connected beams 9 are oscillatory upon the shaft 6, this being for the purpose of angularly adjusting the belt, and for varying this angular adjustment I may provide duplicate devices acting against the respective beams 9, o'neof which will now be described.

Upon the beam 4 shown in the foreground in Fig. 2 and carried by a suitable bearing thereon is a shaft as 14 having a cam as 15 operable by worm gearing denoted in a general way by 16, the worm of said gearing being carried on the shaft 17 rotatably supported by bearings upon said beam 4 illustrated in said Fig. 2. Said shaft l7 is equipped with a hand wheel 18. By turning the two hand wheels, only one of which is seen, I can, as will be clear, through the two cams 15 adjust the angular relation of the two beams 9 and thereby the endless concentrating belt 'll A worm gear is shown at 19, its shaft being supported by a bracket as 2() on the sill 2 shown in the foreground in said Fig. 2. Upon the inner side of this worm gear 19 is a lug 2l coperative with the lug 8 hereinbefore described. A worm 22 on the shaft 23 meshes with the worm gear 19, said shaft 23 being supported by the bracket 20 and by a bracket as 24 carried by the sill to which saidbracket 20 is fastened. On the shaft 23 is shown a pulley 25 connected by a belt 26 with the pulley 27 on the main shaft 2S of the head motion denoted in a general way by 30. The head motion forms in itself no part of the invention, for which reason it is unnecessary to describe the same in detail. Any

suitable head motion may be employed so long as it gives to the endless belt an absolutely uniform accelorated forward stroke and a uniformly retarded rearward stroke. The forward or concentrating stroke of the belt, as will be clear, is transverse of the belt or in a direction extending from the back to the front of the i belt, or, in other words, from the right towards the left in Fig. 3. In addition to such transverse stroke of the belt, which is given to it by the so called head motion 30, it has a traveling movement which is effected in the present instance by the worm 22 and the worm gear I9, the worm receiving its motion from the shaft 28 through operative connections therewith. Owing to the two lugs 2l and 8 to which I have hereinbefore referred, there will always be an operative connection between the worm gear 2l and the disk or wheel 7 so that, even while the belt is being vibrated or reciprocated through the head motion, it is also being simultaneously given its feeding movement. The upper run of the belt Il is supported by several rollers as 3l carried by the connected beams 9. Owing to the presence of these rollers 3l there is no possibility of the upper run of the belt sagging between the rollers or drums 5 and l0 respectively.

The pulp is supplied on to the concentrating belt in any way, for example, by a feed box as S2 shown conventionally in Figs. 2 and 3 and located substantially centrally of the belt Il at the back thereof. l provide two pipes as 33 at opposite sides of the feed box 32 for supplying wash water, said pipes extending longitudinally of the belt at the back thereof also as indicated in said Figs. 2 and 3. The pipes may be supplied with the necessary wash water by pipes as Sli. I have shown the wash water pipes 33 conventionally. The liquid slimes are discharged over the highest end of the belt, while the tailings pass from off the lowest end of said belt, the heavier particles of the liquid slimes passing from the belt near the back thereof, while the heavier tailings are discharged from the opposite end of the belt near the front thereof. The values are discharged froin the front of the belt and, for properly directing the saine therefrom, I provide a discharge apron'as 35 fitting under the front portion of the belt between the rollers 5 and l0 and carried by the forward beam 9, as shown clearly in Fig. 3. Under the upper inclined portion of the belt I] and between the sills 2 I prefer to arrange a tank as 36 to receive the slimes which may adhere to the belt after the drum l0 is passed and, for washing these adhering slimes from said belt, I provide a. wash water pipe as 37 which directs a jet or jets of water against the belt to separate therefrom any slimes which may adhere thereto, the slimes thus separated from the belt falling in the tank 36 It will be assumed that the pulp contains galena, iron, and zinc. Of course, pulp of any suitable kind may be delivered in tothe belt, but I have selected for illustration pulp containing these constituents to indicate the action ofthe apparatus. The pulp is supplied to the central back portion of the belt Il from the feed box 32. The vibratory motion given te the belt by the head motion stratifies the pulp or causes the mineral values to settle in the spaces between the rifiies I2. The wash water is, of course, flowing and aids in keeping the particles in suspension between the riiH es. Such wash water, however, is used primarily to wash the light or worthless material over said riflles l2, but has no direct effect in discharging the concentrates or mineral values over the front of the belt. The discharge of the concentrates is caused by the vibratory motion, the material on each forward stroke of the belt 'all at the extreme upper inclined end thereof.

being moved from the back or feed side toward the front side. As the vibratory stroke has the least effect on the heavier materials such materials are discharged nearest the upper front side of the belt, while the lighter materials are discharged toward the lower front side of said belt. Galena would be discharged near the extreme upper end of the belt, while iron and zinc would be discharged lsuccessively over the front side but between the gatlena and the lowest end of the belt. The quart/J mixed with simili mineral values is discharged at the front of the belt near the lowest end thereof and is subsequently crushed to separate the mineral values therefrom and returned to the apparatus. lhe slimes stick more or less to the belt and cannot be readily discharged therefrom. They are therefore carried up with the belt and fall from the same at the highest point thereof. The slimes which are not thus separated from the belt are washed therefrom into the tank or box 3G by water from the pipe 37. ,lrhe heavier slimes are discharged from the belt near the back thereof, while the lighter slimes leave the belt near the iront thereof, but 'lhe tailings are discharged at the lowest end of the belt, the lighter tailings leaving the belt near the back, while the heavier tailings pass from the belt near the front thereof.

The beams or frame members Li, whether there be two or more, constitute a main vibratory frame while the connected beams t) constitute an auxiliary frame. The auxiliary frame vibrates with the main frame, but is also oscillatory with respect thereto so as to vary the angular relation oi the e nnentrating belt.

W hat I claim is:

1. In an apparatus of the class described, an endless traveling transversely vibratory bell upwardly inclined from one end toward the other and adapted lo discha' mineral values from each end, the belt having transverselydisposed ritlles on the outer side thereof of progressively decreasing thickness t'rom the hack toward the front thereof, a feed-box at the back of the belt between the ends thereof, and ash-water pipes extending longitudinally oi' the feed-box. said belt serving on its vibratory movement to discharge mineral values from the front; thereof.
