Specification of Letters Patent.

Patented Aug. 8, 1905.

Application filed July 13, 1904. Serial No. 216,413.

To It whom it may concern.-

Be it known that I, MARonLLUs P. BAUGH, a citizen of the United States, residing at Pueblo, Colorado, have invented certain new and useful Improvements in Ore-Jigs,of which the following is a specification.

My said invention relates to improvements in ore-jigs of the type designed to use either air or water in effecting the separation of the ore.

In devising the present construction I have aimed to secure a device of extreme simplicity and maximum efficiency and one which shall be economical in operation.

With these and other objects in view the invention comprises the construction and arrangement and combination of parts hereinafter described, and particularly set forth in the appended claims.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a plan view. Fig. 2 is a longitudinal vertical section. Fig. 3 is a side elevation. Fig. 4 is an end elevation. Fig. 5 is a transverse section.

Referring by reference characters to the figures, in which like numbers are used to designate the same or like parts, it will be seen that the numerals 1 1, &c., indicate uprights or standards suitably connected at the top and bottom by transverse beams 2 and by longitudinal beams 3, the whole beingsuitably braced, as shown.

The numbers 4 indicate the hoppers for receiving the separated ore, which are preferably of inverted-pyramid shape, having at the lower end of each'a suitable gate or valve 5 by which the contents of the hoppers may be removed from time to time. I have shown two hoppers in the drawings for the purposes of convenience; but it will be understood that these are merely representative of any desired number, and as a matter of fact I have found the most efficient number to be four, as with this number I get the most effective length of screen-surface. The hoppers are supported by the frame in any convenient manner and have their upper sides closed by the horizontal flexible diaphragms 6, which are clamped at their edges by the plates 7, secured by suitable clamping bolts or screws or any other convenient manner.

The screen box or trough 8 extends longitudinally the entire length of the frame, having at intervals corresponding to the hoppers downwardly-extending portions 8, which are provided with flanges or like devices 8 bolted to the diaphragms, and the diaphragms are provided with openings within the portion bounded by these flanges and corresponding openings are madein the bottom of the screen box or trough, which openings are covered by the screen 9. These screens when in use are bedded with broken ore in the manner well understood by those skilled in the art.

The ore to be separated is fed in at one end through the feed-hopper 10 and discharged from the other end by the delivery-spout 11. The trough is connected at suitable intervals by means of brackets 12, rods 13, and straps l t with the eccentrics 15, carried by the longitudinal shaft 16, which is driven by means of the fast and loose pulleys 18 and 19 from any suitable source of power. Thus as the shaft is rotated the trough receives a vertical move ment, thereby jarring or agitating the material supported thereby, and simultaneously the diaphragms are raised and lowered, thereby etfecting an action similar to that of a pair of bellows and causing pulsations of air or Water (according to which is used) up through the bed of ore, thus securing a lifting effect upon the material to be supported. I prefer to make the connection between the supporting-brackets and the rods connected to the eccentrics an adjustable one, as indicated. The fluid (air or water) is supplied to the hoppers from a supply-pipe 20, connected to any suitable source of supply, which leads to a distributing-box 21, from which a pipe 22 leads to each hopper. These pipes 22 are controlled by an ordinary slide-valve 23, which is operated so as to give an intermittent supply of the fluid to the hoppers. The slide-valve is conveniently operated by an eccentric 24, on the shaft of which is a pulley 25, driven by a belt 26 from a pulley 27.0n a shaft 28. This shaft 28 is more conveniently driven by beveled gears 29 and 30 from a shaft 31, which in its turn is driven by a belt 32, passing over pulleys 33 and 34. the latter being on the main shaft heroinbefore referred to. The branch pipes leading to any one hopper may be provided with globe-valves 35, by which the flow of the fluid to the hopper may be regulated or entirely out off.

In order to eflect the travel of the ore from the feed to the delivery end of the screen box or trough, I provide a rigid frame or side bars 36, in which are journaled transverse pipes 37, which have rows of perforations 37 a in their under sides. Air or water is supplied to these pipes from one end by suitable connections hereinafter described, and as the pipes oscillate through an angle of something less than forty-five degrees the swinging motion of-the jets of fluid exert apropelling action upon the ore, causing it to be gradually Worked along from one end of the trough to the other. The pipes are oscillated by crankarms 38 on the ends opposite the fluid-supply, which crank-arms are all connected by a rod 39, so that they swing in unison. An upwardly-extending arm 40 is connected to a disk 43 on the shaft 28, hereinbefore referred to. The fluid is led to the oscillating pipes from a longitudinal pipe 44, connected to any suitable source of supply. From the pipe 44 branches 45 extend out in line with the oscillating pipes, each branch being connected with the corresponding oscillating pipe by a connection such that while preventing leakage of the fluid the free oscillation of the pipes is permitted. Such a connection will be obvious to those skilled in the art. As a simple example I have shown the connection as made by flexible rubber tubing 46. Each branch pipe above referred to is provided with a valve 47, by which the flow of the fluid may be regulated or entirely cut off at will. I prefer to place opposite the perforations of each oscillating pipe a deflector 47'.

Where air is used, there is apt to be more or less dust. To confine this, I may provide a canvas or like cover 48 over the frame in which the oscillating pipes are journaled, this depending down over the sides and preventing to a great degree the spread of the dust during the separating action, as is shown in Fig. 5.

Having thus described my invention, what I claim is- 1. In an ore-jig, a screen constructed and adapted to have ore fed to one end thereof and delivered from the other, a plurality of oscillating pipes supported above the screen and having delivery-openings, means for supplying fluid under pressure to the pipes and deflectors over the openings of the pipes, substantially as described.

2. In combination a plurality of hoppers arranged in line, a trough extending longitudinally above the same and having openings communicating therewith, flexible diaphragms connecting the edges of the open ings with the edges of the hoppers, a frame supported above the trough, a plurality of oscillating pipes supported in said frame and having delivery openings, means for supplying fluid under pressure to said pipes, a longitudinal drive-shaft above the pipes and eccentrics carried by said shaft having straps connected to the trough for imparting a vertical vibratory movement thereto, substantially as described.

3. In combination, a plurality of hoppers arranged in line, a trough extending longitudinally above the same and having openings communicating therewith, flexible diaphragms connecting the edges of the open ings with the'edges of the hoppers a frame supported above the trough, a plurality of oscillating pipes supported in said frame and having delivery-openings, means for supplying fluid under pressure to said pipes, means for imparting a vertical vibrating movement to the trough connections for supplying fluid to the hoppers beneath the trough and valve mechanism interposed in said connections and operating means for operating said valve mechanism to secure an intermittent supply of fluid through said connections, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.
