ARTHUR FRITSCH, OF ST. LOUIS, MISSOURL.
ORE-CONCENTRATOR.
SPECIFICATION forming part a Letters Patent N0. 671,276, dated April 2, 1901 Application filed September 13, 1900.
To all whom it mag concern: Be it known that I, ARTHUR FRITSCH, of the city of St.Louis, State of Missouri, have invented certain new and useful Improvements in Ore-Concentrators, of which the following is a full, clear, and exact description, reference being-had to the accompanying drawings, forming a part hereof.
- This invention relates to ore-concentrators; and it consists of ,thenovel construction, combination, and arrangement of parts hereinaftershown, described, and claimed.
' Figure 1 is aside elevation showingmy improved ore-concentrator. Fig. 2 is a plan View. Fig. 3 is an end view., Fig. 4 is a detail view of astandard and adjusting-lever made use of in carrying out the invention. Fig. 5 is a view showing the adjusting-lever and the parts carried thereby. Fig. 6 is a detail view showing a portion of the operating mechanism; Fig. 7 is a view showing the means by which the table is operated. Figs.
8 and 9 are detail views showing the adjusti-ng device made use of in carrying out the invention. Fig. 10 is a sectional viewshowinga portion of the table. Fig. 11 is-.a detail view showing the devices made use of to reciprocatethe table. I
In the construction of thisinvention I provide abase-frame l of any preferred construction, and pivoted to one, side of which are transverse ,bars zf'theopposite ends of the bars being connected by the member 3. I ivorally carried by the base-frame 1 on the side opposite from the pivot-ed ends of the-bars 2 are cams 4, upon which the member 3 rests and by means of which the free'ends of the bars 2 may be raised or lowered. Rigidly connected to one of the cams i is an operating-lever 5, by means of which the cam may be turned on its pivot, thereby raising or lowering the ends of ,the bars 2. The cams are- Inade to. operate simultaneously by .rne'ans of a connecting-rod 6, thereby causing the free ends of both the bars to'stand at a uniform elevation.
Secured to the ends of the bars 2 are the upright standard-frames 7, pivotally carried within which are the suspending-links 8, the upper ends of the said suspending-links being ivoted to the said standard-frames and the ower ends of which support the table.
Serial No. 29,931. (No model.)
' A-segmeuti) issupported by-oneof the standard-frames .7, adjacent to the lever 5, and
the locking-cam 10, carried by the lever, operates upon the said segment, thereby holding'the lever and thecanis 4 in any adjustment in which they are placed.
Supported by the lower ends ofthe links 8 are transverse bars 1l,upon which is mounted the bottom of. the table. The said table is constructed in the form of a receptacle and comprises the top 12 and the upwardly-projecting sides 13, whereby the material-is rerained on the table. 1 As shown, the rearend' of the table is broader than the forward end,
the purpose of which will hereinafter appear. Secured upon the top of the table is a section 14 of linoleum, and secured upon the linoleum covering are strips 15 of wood, the rear ends of which, 'as shown in Fig. 2, being curved, the
purpose of which isto guide the ore toward the forward end of the table when the machine is in operation. The rear ends of the strips 15 are thicker than the forward ends, and said strips grad ually taper toward their termination, and the forward ends are arranged in graduated form, those toward the left of the table be-' whiclrit {nay-be delivered to any suitab1e receptacle. 18indicatesacorrespondingtrough carried by the side of the table into which the sludge is delivered after the ore has been removed therefrom.
Supported above the rear end of the base 1 are brackets 19, carried by which is an operating-shaft 20, and keyed upon one end of the said shaft is a belt-pulley 21.. Carried by the shaft 20 between the brackets 19 is an eccentric 22, suspended from which is a wedgeshaped member 27-3,- the function of which is to operate the table. larried between the bracketslQ is a roller 24, and extending rearwardly from the table between the brackets 19-is a U-shaped frame 25, carried by which is a roller 26, corresponding to the roller 24.
The lower end of the wedge 23 operates between the said rollers,and whenever the driveshaft is rotated the said wedge is recipr0-' ing laterally. Carried by the brackets 19 below the rollers 24 and 26 is an integral member 28, and connected to the forward end of the said member is a .rod 29, which projects forwardly into a-suitableopeniug in the rear end of the table and carries on its forward end a washer 30. Acoil-spring 31 is arranged around the-rod 29 within'the table, the ends ofthe said'coil spring bearing against the washer 30 and the end of'the table, respec tively. By this means the table will be thrown back toward the brackets 19 afterthe wedge 23 is raised from between the rollers 24 and 26. In operation the shaft 20 is retated by applying motive power to the belt 21. This alternately raises aud'lowers the wedge 23, causing it to pass between the rollers 24; and 26, whereby the table will be op ""erated forwardly, as above described. As
the shaftis continually rotated and the wedge 23 is raised from between the rollers 24 and '26 the tension of the spring 31 serves to throw the table again toward the brackets it), thereby imparting; a continuous reciprocatory movement to.the table. The material duriug the operation is fed into the trough l6,
bel t from which it passes gradually onto the top of the table and is guided therefrom by means of the strips 15, the ore being gradually led into the trough 17 and the gangue and sludge 0 passing into the trough 18.
One side of the table may be raised or lowered in order to facilitate the movement oi the ore and sludge by manipulating the lever 5, and thereby operating the cams 4 in the manner described. The small rollers 32, carried by the under side oi the bar 3, operate upon the cams 4, thereby causing their operation to be free and without friction.
series of curved and tapering, guides for regu- 6o latiug the movement of the ore, an operatingshaft, means operatedby the shaft for l'orcinn the table rearwardly \vheu'ei' er it is rota ted, and a separate means fondrawiug the table to the front, substantially as specified.
In testimony whereof I allix my signature in presence of two witnesses.
ARTHUR unify-sen.
