CONCENTRATING-TABLE.
Specification of Letters Patent.
Patented Il une 13, i916.-
Applicaton le. September 28, 1915. Serial No. 53,042.
To all whom t may concern:
Be it known that I, HOWARD A. MGCLEL- LAND, a citizen of the United States, residing at Allensworth, in the county of Tulare and State of California, have invented new and useful Improvements in Concentratingrlables, of which the following is a specification.
This invention relates to a concentrating table.
One of the objects of the present invention, is to provide a simple, compact, cheaply manufactured, easily operated and adjusted concentrating table, which is constructed to secure the concentrating effect of a vanning and iowing stream, and the stratifying and feeding action of reciprocal, vibratory or differential shake movement.
Another object of the invention is to provide means for deflecting the gangue matter passing over the table and ,simultaneously converging or gathering the separated material to enrich or thicken same at a plurality of points along the flow surface of the table, to permit a continuous and complete removal of same.
Further objects will hereinafter appear.
The -invention .consists of the parts and the construction and combination of parts as hereinafter claimed, having reference to the accompanying`drawings, in which- 4igure 1 is a plan view of the table proper. Fig. 2 is a side elevation of same, showing the application of one form of mechanism for imparting a reciprocal, vibratory, movement. Fig. 3 is an enlarged detail section on line 3-3, Fig. 1. Fig. 4 is a cross section on line 4-4, Fig. 1.
Referring to the drawings in detail, A indicates the table proper, which' is constructed of wood, metal or any other suitable material and faced with a linoleum cover. vThe table shown in the present instance, is of the two-trough sluice box construction and each side is similar lto the other. The construction of vone side will hereinafter be described.
Arranged centrally between the side iianges 2 of the table, at a suitable distance from the pulp or feed box 3, is an auxiliary water supplying casing 4, to which water is delivered from a pipe 5, mounted on the lower side of the table,
more fully described and and connected with a suitable source of supply, not here shown, the volume of water admitted being controlled by a valve 6. Formed on the forward end of the casing 4, is any elongated, flat discharge nozzle 7 and mounted interior of said nozzle is a skimmer plate 8, which is adapted to be adjusted vertically, by means of the screws indicated at 9. This skimmer plate is horizontally disposed and forms a cover for a discharge opening 10, in the table, which is provided for the purpose of permitting a continuous discharge of con-` centrates.
The table proper is mounted upon spring legs 117 and a reciprocal, vibratory movement is imparted to the table through a five-point toggle, generally indicated at 12, which is similar in construction to that used upon well-known Wilfley tables. This particular mechanism does not, however, form any important part of the present invention, and may, therefore, be varied or changed to suit conditions. Mounted on the table surface, is a pair of gathering boards 13 and 14; these boards are triangular in shape when looked upon from a plan view, and are disposed, one on each side ofthe nozzle. The sides of each gathering board are vertical, as indicated at 15, while the top faces are inclined outwardly as indicated at 16. The purpose of this construction will hereinafter be described.
The gathering boards are rather"` long and their inner walls present converging faces which are provided for the purpose of converging or gathering the concentrates and directing same directly into the mouth of the discharge nozzle.
In operation, as previously described, a reciprocal, vibratory action is imparted to the table, by means of the mechanism, generally indicated Nat 12. With this in operation, and pulp supplied by the feed box 3 and with the table inclined from the-feedY to the discharge endfit will be seen that -the pulp will travel over the table surface in the" direction of the arrow a. The pulp will in this manner, be subjected to the concentrating 'effect of a vanning,V and owing stream and also to the strati ing and feeding action of reciprocal, vibratory movement. The pulp, consisting of finely crushed metalliferous ores or sands, together with the right proportion of water deposited upon the table surfaces from the feed box 3, is
immediately subjected to the/concentrating tical sides 15 of the gathering boards. The
concentrates A.will in this manner be vconveyed directly to the mouth of the nozzle, where the gangue is deiected or thrown back by the outwardly flowing current of water supplied by pipe 5, and regulated by valve 6. This outward discharge of water however, only eiects the gangue as the skimmer plate 7 covers and protects the thlckened layer of concentrates against the actlonof the water. The concentrates will thus be permitted to pass under the skimmer plate, where they are finally discharged through the opening 10 by a receiving launder, not here shown.
The differential shaking action lmparted to the table, together with the outwardly inclined faces 16 formed on the gathering boards imparts a lateral wave or vanning movement to the water and the pulp disposed between the gathering boards and this vanning movement, not only permits a constant discharge and removal of the gangue over the faces 16 on the gathering boards, as the pulp mass as a whole is converged by the vertical sides 15, but also produces suihcient agitation to permit the concentrates to separate and stratify bythe vibratory movement. The greater mass of pulp is sheared olf or deflected by the gathering boards before the concentrates reach the mouth of the discharge nozzle and the pulp' thus deflected, runs down the inclined face of the gathering boards in the direction of arrows b, from there they reach the concentrating surface of thetable where they are again similarly treated between a pair of deflecting boards and anozzle, such as shown. Any concentrates lost or passing over the iirst set of the gathering boards, will thus be caught and discharged through la second nozzle, in this manner permitting a perfect precipitation and separation of the values, before the pulp or gangue finally reaches the tail end of the table.
By the employment of the concentrating table, constructed as here shown, it is found that careful preliminary sorting or separating of the various particles ofcrushed on comminuted material into different grades or classes, in which each separate class shall be composed of 'particles as nearly practicably of the same relative size, is not necessary, in other words, the tableA will handle .tally disposed table,
classed as slimes or two hundred mesh. The' several actions, such as is caused by vanning, vibration, etc., permit perfect separation and participation of concentrates, whether coarse or line, without sorting or previous separation. A
The materials and finish of the several parts of the device may be such as the judgment and experience of the manufacturer may dictate.
I wish it understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims, Aand that I do not wish to limit Amyself to the specific design and construction here shown.
Having thus described my invention, what I claim and desire tosecure by 'Letters Patent isf- 1. A concentrator Acomprising a horizontallydisposed table, means for imparting a differential shake movement t0 the table, an auxiliary water supplying casing centrally disposed on the table, said casing having` an elongated flat discharge nozzle formed thereon, a skimmer plate mounted in the nozzle and forming a cover for a concentrate discharge opening, and a pair of angularly disposed gathering members secured on the table, one in each side of the nozzle.
