No. 219,050. Patented Aug. 26,1879.

IMPROVEMENT IN AUTOMATIC MINE-DRAINING APPARATUS.
Specification forming part of Letters Patent No. 219,050, dated August 26, 1879; application filed June 9, 1879.
To all whom it may concern:
Be it known that I, JosEPH R. WILCOX, of the city and county of San Francisco, and State of California, have invented an Automatic Mine-Draining Apparatus; and I here- ,set. Each set of cylinders is placed in line, so
that one piston-rod may carry three pistons, one for each cylinder. Two pipes connect with opposite ends of each of the central cylinders, so that a continuous pipe leads from one end of the inside central cylinder up and out of the mine, down to one end of the outer central cylinder, andthence from the opposite end of said outside central cylinder up and down into the mine, connecting with the other end of said inside cylinder, thus forming a continuous double water-column'when said pipes are filled and sealed.
The two outer inside cylinders, which are provided with suction-pipes, are connected by separate pipes with a centrally-placed pipe,
which discharges into an opentank at the surface, said pipe being continued down the outside from said box, where it is connected with the two outer outside cylinders by separate pipes provided with valves or cocks, said outside cylinders being provided with dischargepipes controlled by cocks.
By allowing the water which flows down the central outside pipe from the box to discharge first into one of the outer outside cylinders, and then into the other, alternately, the pis-- tons of said cylinders are operated by the crates, first one wayand then the other, the
piston in the central insidecylinder. As this piston is moved back and forth it moves'the alternate pistons of the outer inside cylinders, so as to force the-water up the central inside short pipe, which empties into the box, said water thus being forced to the surface by the weight of the heavier column outside. The heavier body of water in the longer pipe outside is thus utilized in raising up the water in the inside shorter pipe, said shorter pipe at the same time giving the water-supply to the outside one.
In this way the Water may be raised from mines in such localities as offer facilities for a proper fall by a very simple application of the heavier part of a column of water to a series of pistons moved by saidvwater.
In the accompanying drawings, Figure 1 is a perspective view of my invention- Fig. 2 is a plan view, showing the arrangement of valves.
Two pipes, A B, extend down the shaft in the mine, or down a well, and, on reaching the surface, are led down in any direction, so that their outer ends are at a lower point than the ends in the shaft. The ends of the pipes in the mine open into opposite ends of a com mon cylinder, C, in which is a piston, to, on a rod, b. This rod extends through both ends of the cylinder, and each end of the rod is fitted with a piston, f g, which play in independent cylinders D E. Each of these cylinders D E is provided with an inlet pipe or valve, 0, which leads to the sump' in the mine or the water in the well, and through them the water is admitted to the cylinders, as hereinafter described.
At the end of the pipes A B outside the shaft, and lower down than the inner ends, is a similar arrangement of cylinders and pipes. The pipes A B open at the opposite ends of a cylinder, C, having a piston, to, on a rod, 12, said rod 1) extending through both, ends of the cylinder, and having pistons f g, which play in independent cylinders D E, as shown. Each of these cylinders D E is provided with a discharge-pipe, d 0', each pipe being provided with a cock, as shown.
From the cylinders D E in the mine or well lead two pipes, F G, one from each cylinder, and opening into a common pipe, H, which leads upward and opens into an open box, I, on the surface at the top of the mine. From there a pipe, H, which is really only a continuation of the pipe H, runs down outside to the outer lower cylinders, D E, with which it is connected by pipes F G, one of which leads from each of said cylinders to the pipe H. cocks h i, as shown, by means of which communication may be out off from either cylinder, as desired, for the purpose hereinafter described.
The pipes F G, leading from the cylinder D E to the pipe H, are provided with checkvalves d, as shown.
Priming-valves e are placed at the upper bends of the pipes A B, by which said pipes may be supplied with water to replenish them in case any waste occurs.
In order to operate my pumping apparatus, I first fill the pipes A B with water by means .of the primingvalves 0, or in any desired or convenient manner. The outer cylinders, O D E, must be, at apoint outside the mine or 'well, lower than the point at which the cylinders O D E are situated, the two sets of cylinders being connected by the pipes, as herein described. This is necessary in order that the column of water in the pipe H outside the mine shall be enough heavier than the column in the pipe H to overcome the weight of water in said pipe H, and the friction of moving the water in the pipes, moving the pistons and valves, 860., as hereinafter described.
When the pipes A B H arecompletely filled with water the device may be set at work.
It may be supposed that the piston f in the cylinder D on the outside of the mine has completed its outward stroke and is at the outer end of the cylinder. In that case the piston a of the central outer cylinder 0 is at that end of said cylinder nearest the cylinder D, and the piston g of the cylinder E is at that end of the cylinder E nearest the central cylinder, by reason of all three pistons being on the same rod. I then close the cook it in the pipe F and open the cock in the discharge-pipe d of the cylinder D, so that the water may flow out of said cylinder through said discharge-pipe. At the same time I open the cock i in the pipe G, leading from the central pipe H to the cylinder E and close the cock in the discharge-pipe cof said cylinder.
The water in the long central pipe H then flows into the cylinder E through the pipe G and forces its piston g over, thus drawing over, by means of the rod 1), the piston a of the central cylinder 0 and the piston f of the cylinder D, forcing the water through the discharge-pipe d.
As the piston of the central cylinder 0 is thus drawn over it pushes the water up the pipe B, which column is'balanced by that in the pipe A. As the column of water is pushed These pipes F G are provided with.
each other, so that there is nothing for the piston a to overcome except the friction of the water in the pipes A B, as far as the contents of those pipes are concerned.
In moving this continuous column of water contained in the pipes A B, however, the pis ton to in the cylinder 0 is moved from one side to the other, as before described. In being thus moved the piston-rod b, common to the three cylinders (J D E, is moved over in the direction of the cylinder D, taking with it the two pistons f g of the cylinders D E. As these pistons are thus drawn over, that one in the cylinder D draws water into said cylinder from the sump or well through the inletpipe 0, thus filling said cylinder, the checkvalve d in the pipe F preventing any water flowing back into the cylinder from the pipe H. The moving over of the piston g in the cylinder E forces the water previously drawn into said cylinder through the pipe G into the center pipe H, and thence up into the box I on the surface, whence it will flow down through the pipe H, and be utilized in operatin g the outside pistons for the reverse stroke.
As soon as the three pistons a f g in the cylinders O D E are all over nearest the outer end of the cylinder D, and the three pistons afg in the cylinders C D E are all over nearest the outer end of the cylinder E, the reverse action takes place. The water from the pipe H. is allowed to flow into the cylinder D behind its piston, and move said piston out, thus drawing over the pistons a 9, discharging the water from the piston E, and reversing the motion of the water in the central piston and pipes A B. In so doing the central piston of the inside cylinder 0 is moved back again, drawing the water into the'cylinder E and forcing it out of the cylinder D into the pipe H, and so to the surface.
In this way the weight of the long column of water is utilized in forcing up the short column, the Water in the pipes A B acting as a belt or rope in moving the piston in the central cylinder.
By suitable connections and mechanism the action of the cooks in the pipes F G d 6 may be made automatic, and the water from the central pipe H be shifted first into the cylinder D and then into E, operating the pistons alternately.
Priming-cocks 6 may be placed at the highest point of the pipes A B, by which they may be filled. I prefer to seal these pipes up and ,put clear water in them, so that the central cylinders will not become worn by gritty water from mines. As any leakage occurs the waste may be supplied through the priming cocks or valves 0.
The use of the central pipe H H is not essential to the operation of the device other than for the purpose of allowing the gritty water to flow through. By connecting the pipe F from the cylinder D with the pipe B, and connecting the pipe G from the cylinder E with the other pipe, A, the operation will be the same, the Water being then drawn up alternately through the short leg of one pipe, A, and then the short leg of the other one, B. I prefer, however, to operate the pistons in the manner described.
Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, isi 1. The cylinders G G, with their pistons a a moving in said cylindersfln combination with the water-containing pipes A B, connecting the corresponding ends of said cylinders, whereby the motion of the piston in one cylinder is communicated directly to that of the other by the alternate action of the column of water contained in the pipes, substantially as herein described.

In witness whereof I have hereunto set my hand.
