Application filed March 5,1906. smart). 304,162.
sidin-gat Seattle, in the county of King and Stateo'f Washington, have invented certain 'newand useful Improvements in Concentrators,-of which the-followingis a specification, -reference being had therein to the accomxo :pari-yin'g drawings, in which- Figure 1 is a longitudinal vertical section of; apparatus embodying our invention. Fig. 2 is a perspective view of the riffle-frame shown detached, and Fig. 3 is a cross-section-a1 view taken through 3 3 of Fig. 1.
{This invention relates to concentrators, and -inore-particularlyto apparatus employed forthe separation of the'more valuable metalliferous particles from mill-tailings or aurif- 2o erous sands and gravels.
The object of'theinvention is=the provision of simple and economically constructed means wherebythe separation and savingof the precious metals are accomplished with but 2 5 little waste and With'a-relati vely'small consumption of water.
With these ends in view the invention consists in the novel construction, adaptation, and combination of parts, as will be herein- 0 after described, and pointed out in the appended claims.
Referring to the drawings, A represents a chute made desirably rectangular in crosssection, as shown, and arranged upon 'sup- 3 5 ports, such as B, to have a slope downwardly toward the delivery end. At the receiving end of the chute is a hopper C, having a dischargeopening C with a vertically-slidable gate D for wholly or partially closing such opening.
40 Positioned above the hopper is a trough E,
having in its bottom a riddle or grizzly E for separating the coarse stones from the material being treated and allowing only the smaller screened particles thereof to fall into the hopper accompanied by water.
F is a riffle-frame of a width adapting it to be placed within the said chute and desirably of such length as to extend from a cleat B at the discharge end of the chute to within the opening C of the hopper, whereat the opposing faces 0 and f are inclined, as shown, to afford an interstice therebetween for the insertion of a packing-piece G, of rubber or other suitable material, and provide a non-leakable .joint. The said frame'is' comprisedofatop F and sides'F" and is provided interiorlywith alternately-disposed riffles H and deflectingbars K. Of these the rifiles are disposed at suitable intervals apart and extend upwardly from a plane projected through the lower edges of the sides F 'to within a short distance of the under side ofthe top F, while the bars extend downwardly from the latter and are of less depth than the frame sides. This frame is likewise provided with -'a slidable gate L in proximity of its discharge end.
M is a coarse woven fabric, ofburlap or the like, which is laid in thebottom of the chute and retained in place bythe riflie-frameresting thereupon. I
The material operatedupon is supplied'to the trough E, into Whichwaterfiows, and, as before stated, isscreened by the riddle, causing only the finerportions of the material,together with the water, falling into the hopper, whence it flows in a commingled statethrough the said chute and riffle-frame. This stream by being intermittently diverted bythe successive action oftherifi'ies and bars assumes an undulating coursewhich affects the heavier metals or concentrates, being entrapped by the riflies or underlying fabric. By the employment of the deflector-bars the extremely fine particles or float-gold is repeatedly precipiitated downwardly to be collected as aforesai Should the riffle-frame from any cause become choked, then the water will rise in the hopper until its head or pressure is capable of dislodging the obstructions, and by manipulating the said gates the action of the apparatus may be adjusted to meet a variety of conditions due to the quality of the material being handled or the normal pressure or quantity of the water available.
To clean the apparatus, the gate D is first closed and the riflie-frame removed from the chute, when upon opening this gate the concentrates can be washed down to the chutecleat for removal.
As is obvious, the operation of the invention is accomplished by the flow of water, and its efficiency is due to the undulating course imparted thereto. There are no parts of the apparatus liable to get out of order, and the only attention needed is to not overcharge the receiving-hopper and the proper adjustment ofthe gates according to the demand.
down by the hopper, said frame embodying sides and a top, with alternately-disposed riffies and deflector-bars arranged in difierent planes, the deflector-bars engaging the top of the frame and the rifiies being free from engagement with the top of said frame, and a "fabric layer on the bottom of the chuteand on which the riffles of the frame rest.
2. In apparatus of the class described, the
combination with the chute having a cleat at its delivery end, and a hopper provided with a discharge-opening communicating with the chute, of a frame adapted to be placed within said chute with its outer end engaging said cleat and its inner end extending into said discharge-opening, said frame being formed with sides and a top with alter nately-disposed riflies and deflector-bars which are arranged in different planes, a layer of fabric intermediate the frame and the bottom of the chute, and a gate for said discharge-opening.
3. In apparatus of the class described, the
i combination with the chute having a cleat at its delivery end, and a hopper provided with a discharge-opening communicating with the chute, of a frame adapted to be placed within said chute with its outer end engaging said cleat and its inner end extending into said discharge-opening, said frame being formed with sides and a top with alternately-disposed riffles and deflector-bars which are arranged in different planes, a layer of fabric intermediate the frame and the bottom of the chute,
a gate for said discharge-opening, and a gate for the delivery end of the'frame.
4. In apparatus of the class described, the combination with the chute having a cleat at its delivery end, and a hopper provided with a discharge-opening communicating with the chute, of a frame adapted to be placed within said chute with its outer end engaging said cleat and its inner end extending into said dischargeopening, said frame being formed with sides and a top with alternately-disposed rifiies and deflector-bars which are arranged in different planes, a packing-piece for making a non-leakable joint between the hopper and the frame, a layer of fabric intermediate the frame and the bottom of the chute, a gate for said discharge-opening, and a gate for the delivery end of the frame. In testimony whereof we afiix our signatures in presence of two witnesses.
