To all whom it mag concern: it
Be it known that I, ALFRED-EDW N DAvIs, a SUlQJGClJ of the King of Great Britain, and
resident of Johannesburg, Transvaal, have invented certain new and useful Improvements in Pumps and theLike, of which the followingis a specification; v
The resent invention relatesto applica Is for pumping mine tailings, ticles of pulverized oremixed with water -or other liquids, liquids containing other gritty pumps or solid matter injsuspens'ion, acids or the.
like. V,
The improvements maybe appliedeither in the manufacture ofpumps speciallyihtended for any of the above purposes, or to any "of the existing types 0f] oscillatory.
pumps, to adapt them for the purposes hereicirculation through the main operative parts of the pump, of, the liquidjoontaining the solid matter, and so obviate'the, excessive wear and tear which resultswhenthepumps 1 of the ordinary construction are utilized for any of the abovementionedpurposes.
My invention consists'of a chamber or vessel (or chambers or vesselslinterposed between the oscillatory' media or mechanism of a pump and the mainvalvesthereof, in
' which. chamber a: flexible vibrating. diarate the clean waterson theoscillatory or phragm is so arranged and fixedias tojsepae operating side thereof 'fromthe liquidor water charged with. tailings, slime, gritty or ,7 solid matter, acid et cetera, on the side thereof in connection with .the main suction and delivery valves ofthe pump. This arrangement allows the clean {water circulating in; the working parts of the pump to: be"con-' stantly retained therein, oscillating backwards and forwards in thesaid working and vital parts of the pump, while by means of theflexible diaphragm, the Water containing the tailings,slime or other solid matter, a'cid',
et cetera is retained in thatportion of the ump containing'the main suction and delivery valves, andoirculates in thisportion' only of the pump. o f r In existing pumels'l employed'for the purposes specified the 'quid pumpe'dis allowed to enter, and circulate through theworkingportions of the ump, which 'causes exces sive wear. in such parts; through friction,

7 regulating themovementof the flexible diaphragmin each'direction, thereby obviating the transmission of any appreciable strain to said diaphragm. I also preferably provide a" supply (and relief mechanism by means of which the quantity of clean Water circulating in the working parts of the pump and on each side ofthe piston there of, is kept constant, so that the effective worklng' of the pump will not be impeded or ,im aired by any leakage of the fluid throug the glandsor past the piston.
The invention will now be described in deaccompanying drawings, wherein; 1
': F igure l is a vertical sectional elevation of a diaphragm chamber and flexible vibrating diaphragm, also illustrating a form of supply andrelief mechanism. 4 Fig. 2 is a part sectional plan of Fig. 1, on line xx.
In applying the invention to an ordinary Cornish orplunger pump, or to a ump in which, the suction and delivery va ves are detachable from the pump body, and are availablefor use as the main suction and delivery valves for. thecirculation of the dirty Water, tailings, slimes, 'et cetera, I insert the diaphragmchamber between the pump barrel and the main valves, and to insure the efficient working of the pump I provide small supplementary suction and delivery valves for each pumpbarrel, providing also a suitable port or ports'for these valves, either on the pump barrel, connecting pipe, or clean Water sideof'the diaiphragm chamber. Inthedrawings illustrate a diaphragm chamber, flexible vibrating diaphragm and supply and relief mechanism, suitable for a Cornish or other pump inwhich the suction and delivery valves are available for use as the main suction and delivery valves.
7 B is achamber or vessel of any convenient shape and size. The chamber or vessel B- is formed bythe upper and lower parts D D which maybe bolted or otherwise suitably fastened together round the edges of the central flanges d d, and between which is secured the rim or edge of the flexible vibrat-v The diaphragm oan be leather, canvas or other textile fabric of suit+ able texture, et cetera,lor even thin corrugatedmetal, providedthatit will not allow the tailings or other solid matter to pass through it, thoughit may be of such a nature as to allow water to filter or pass through it if so desired. The lower part D is shaped to form a flanged coupling or connecting piece or pipe E which connects the portion of the chamber B below the diaphragm K with and between the main suction and delivery valves. The upper part D of the vessel B is also shaped to form a flanged coupling or connecting piece or pipe C which may be connected to an ordinary reciprocating pump having its suction and delivery valves attached thereto in the usual manner; that is to say, the connecting pipe 0 is at tached either to the working barrel or to the valve chambers of the pump in such a manner that it (the pipe C) is in direct com munication with a space provided above the ordinary suction valve at either end of the pump. These ordinary suction valves and delivery valves, that is to say those which are directly attached to and form an integral portion of the said pump, are so loaded or weighted by springs, weights, or
- remain closed and inoperative.
otherwise, that during the ordinary working of the pump the main suction and delivery valves are operated, while the ordinary valves attached to the pump, being weighted, Further, in the event of the pressure in the working barrel of the pump being increased from any cause, this increase of pressure overcomes the load or increased resistance of the ordinary valves, and thus causes water to be taken in at the pump suction pipe, or forced out at the pump delivery pipe, in the or dinary manner.
In the construction illustrated the central portion of the flexible vibrating diaphragm K is arranged and secured between two disks L L which may be made of metal or other suitable material and be bolted or otherwise suitably fastened together on each side of the diaphragm K in order to render the central portion of thediaphragm stiff and unyielding. Any other equivalent means may be employed provided that this result is attained.
In the upper portion D of the diaphragm chamber B and attached to the disks L L is a guide rod N. This rod Nis bolted or otherwise attached to the disks L L at the center, and is arranged vertically thereon.
A tubular guide 0 is screwed or otherwise fixed in the upper part D immediately above the center of the diaphragm K in which the rod N works, thus guiding the diaphragm K so that it vibrates centrally and uniformly in the chamber B. The rod N is provided near its upper extremity with a projection P which slides in a longitudinal slot in the tubular guide 0, and is adapted under certain conditions to engage the bifurcated extremities of two levers or arms T and Z pivoted in the upper portion of the chamber B.
Q is a valve which closes against the pres- Should the projection P engage the arm or lever Z the valve R is opened, thereby allowing clean water to enter the pipe C through the supply pipe X. These valves Q and R can be kept closed by suitably weighting the levers Z and T or by means of springs, or in any other suitable manner.
The sole function of the diaphragm K is to keep the clean water in the top portion of the chamber B and the water carrying the tailings et cetera, in the bottom of the chamber B or below the diaphragm K, from coming in contact, and so mixing. Thus the clean water is confined to the barrel P and the connections above the diaphragm K, and the water carrying the tailings, slime or other solid matter in suspension, is confined to the lower portion of the chamber B and the connections between the diaphragm K and the main suction and delivery valves.
The operation of the relief valves Q and it may be described as follows :In the first place the diaphragm K is so arranged that in its ordinary working stroke it vibrates within such limits that the projection P on the rod N moves between the extremities of the two levers T and Z without actually touching them. Should the water in the chamber B above the diaphragm K become diminished, the diaphragm is drawn upwards beyond the limit of its normal upward stroke and the projection P thereupon engages the extremity of the lever Z which opens the valve R and allows clean water to pass into the pipe C from the relief pipe X, and thus sup )ly any deficiency. On the other hand, should there be a surplus of water in the chamber B above the diaphragm K, the diaphragm K is forced below the limit of its normal downward stroke, and the projection P on the rod N engages the extremity of the lever T which operates the valve Q to allow the surplus water to be forced out to waste. The diaphragm is so arranged that it allows the valves Q and R to open fully without becoming taut or strained. Thus no strain is placed on the diaphragm, due to leakage or otherwise of the clean water in any of the parts of the apparatus above said diaphragm, and any deliciency or surplus is thus automatically rectified.
I will here remark that my invention. is not restricted to, nor do I limit myself to the particular arrangement of valves or mechanism shown or described. I may use any other alternative arrangement by which the essential results described may be produced. Valves, or other suitable means maybe also sure in the pipe C and is operated by the 1 provided for the purpose of allowing the cscape of air from the diaphragm chamberpetf cetera, due to startingthe a paratus, or
forking the main suction. and de iveryvalves during working, if these; be found-necessary What I claim as myinventionanddesireto protect by Letters Patent is 1. In'a'pump of, the nature indicated, a
