ELEVATING ROTARY PUMP.

UNITED STATES PATENT OFFICE.

WILLIAM BALL, OF OHIGOPEE, MASSACHUSETTS.

PUMP FOR ELEVATING WATER MIXED WITIT MINERAL SUBSTANCES.

Specification forming part of Letters Patent No. 8,602, dated. December 23, 1851; Reissued September 12, 1854, No. 276.

T0 all whom it may concern:

Be it known that I, VVILLIAM BALL, of Chicopee, in the county of Hampden and State of Massachusetts, have invented a new and useful improvement in rotary pumps or machines for elevating from a lower to a higher level a mixture ofwater or liquid and auriferous sand or other mineral matters in a state of comminut-ion; and I do hereby declare that the same is fully do scribed and represented in the. following specification and accompanying drawings, letters, figures, and references thereof.

In conveying from a machine for washing ores to an amalgamating machine, water charged with auriferous sand or gravel a rotary pump or elevating apparatus is found very convenient as it avoids the necessity of placing .thewashing machine at a level above the top of the amalgamator. A machine such as I have heretofore used consisted of a circular drum or chamber having a fan wheel revolving in it and so arranged or constructed as to receive the mixture of Water and earthy particles through the central part of one side of the chamber and drive or throw it up through a pipe leading out of the top or periphery of the drum. As of necessity the axle or shaft of the rotating fan wheel must pass through and rotate in one side of the drum or case, it has been found that it or the hole through which it passes soon becomes worn to such extent as to enable much of the sand and water to escape out of the pump and through the said hole or space between it and the shaft, suchwear often being so great as to create a serious waste when au riferous sand is running through the pump, such waste often amounting to two or three dollars worth of gold per day. The wear of the various parts of the pump in consequence of the sand or gritty particles becoming introduced between varlous of the still and moving surfaces of the pump has been a serious evil and which it is the object of my improvement or improvements to prevent to a very great degree.

Figure 1 of the aforementioned drawings represents a top view of one of my improved ore pumps or elevators. Fig. 2 is a view of one side of it. Fig. 3 is a view of the other side of it. Fig. 4 is a vertical, central, and longitudinal section of it, and

Fig. 5 is a vertical, central, and transverse section of it.

In the said drawings A denotes the outer case of the pump which case is composed of two meniscus shaped plates (Z, c, placed and confined together with their convexities outward or in opposite directions to each other. They have flanched peripheries that are confined together by screws (4, a, &c. An induction opening or passage 6, is made through the central part of one of the plates, viz. e, which opening leads out of a hopper or trough f, that is cast or formed on the side of the part c, and so made as to be capable of receiving the liquid auriferous mud and allowing it to flow into the passage 6, such mud or mixture of ore and water being con-- veyed into the trough f by means of a spout leading from the ore washing machine.

A fan wheel B plays or rotates within the case A, it being mounted on an axle D, which extends through the central part of the disk (Z, and 'is supported in bearings h, 2', made on a frame F which is secured to the outside of the case A, or placed as seen in the drawings. The said axle or shaft has a driving pulley G, fixed on it around'the periphery of which pulley an endless belt from a driving drum is made to play or run.

To the internal surface of each disk I screw or aflix a circular metallic ring 70, or Z, which has a form in cross section as seen in Fig. 5. These rings divide the internal part of the case A into two concentric chambers m, n, which are connected together by a very thin space 79, left between the two rings. The fan wheel B, rotates within the inner chamber m the form of the fans being rep resented in the drawings, they being of a lozenge shape or approximation thereto.

Out of the external chamber and tangentially to it or thereabouts I carry the discharge pipe K. The object of the two chambers m, a, connected by a thin passage just wide enough to allow the requisite quantity of the sandy liquid to flow through it, is to prevent wear of the joint or packing between the two plates (Z, c, for it is found that without some such an arrangement or means the rapid rotation of the water and sand in the case A caused by the fan wheel will very soon wear out the packing and the joint. In my improved pump the greater part of the rotation of the liquid takes place within the inner chamber while the liquid in the outer concentric chamber in consequence of the back pressure of the column of water in the discharge pipe scarcely revolves, or does so to so small an extent as to do no very material damage to the outer packing or joint of the plates of the case A.- Whenever the rings 70, Z, are too much worn they may readily be removed and others substituted as they are liable to wear out very soon.

Closely surrounding the axle or shaft D (but not sufiiciently tight to prevent the rotation of the shaft), and against the plate or disk (Z of the case A, I make a chamber 9, and within the said chamber and on the shaft I place and fix a small wheel r whose side is nearly in contact with the side of the case A. At the bottom of the chamber (7 and through the plate d of the case A, I make a small hole or passage 25 leading from the chamber into the case A.

Whatever water and auriferous sand that may work through the shaft hole of the case A, will flow against and be caught by the wheel 1-, during its rapid revolutions, and be thrown toward and off the periphery of the wheel and against the contiguous .surface of the chamber g, and from thence will descend toward and pass or be sucked through the passage t and into the case A. The wheel thus prevents the water and sand from coming in contact with that part of the chamber 9 which is immediately contiguous to and surrounding the axle, and thereby'not only prevents wear of the shaft hole of the chamber but the escape of the fluid and sand and consequent loss of gold or metal.

I claim- The improvement by which the waste, auriferous, or earthywater that leaks out of the shaft hole of the case A is saved and returns into the body of the case, and the wear of the shaft hole of the chamber q prevented, the said improvement consisting in the chamber g, the wheel 1", and the passage t, as combined together, connected with the case A, and the shaft of the fan wheel, zftingl made to operate substantially as speci- In testimony whereof I have hereto set my signature, this third day of November A. D. 1857.
