SPECIFICATION forming part of Letters Patent No. 638,890, dated December 12, 1899. Application, led February 14, 1899.` Serial No. 705,480. (No model.)
To all whom, it may concern:
Be it known that I, THOMAS J. SPARKS, a citizen of the United States, residing at Magalia, county of Butte, State of California, have invented an Improvement in Pumps; and I hereby declare the following to be a full, clear, and exact description of the same.
My invention relates to certain improvements in double-acting pumps.
It consists, essentially, in details of construction, which will be more fully explained by reference to the accompanying drawings, in Which- Figure l is a vertical section of the pump. Fig. 2 is a detail of the pipe connections. Fig. 3 shows the manner of connecting the pumprod sections. Fig. 4 is a top view of the plunger, the upper disk being removed. Figs. 5 and 6 are details of the pump-rod packing.
The object of my invention is to provide improvements in that class of pumps having a plunger reciprocating in the pump-cylinder and two sets of suction and discharge pipes and valves connecting, respectively, with the opposite ends of the cylinder, discharging into a common conductor, thus making a doubleacting pump.
The body of my pump consists of a steel cylinder A, within which the plunger reciprocates. This cylinder is detachably connected at opposite ends with the cast heads B. These heads are in the form of a cross, having two extensions l) in line with the cylinder A, the lower one of which is closed. The upper one receives the upper cylinderhead, with its stufng-box, through which thel plunger-rod passes. At right angles with these extensions are the extensions b. The upper and lower extensions b on one side connect with the suction and inlet pipe D, while the two upon the opposite side connect with the discharge conveying-pipe D'. The extensions b and b on the cast heads B are screw-threaded upon the outside. These extensions are adapted to receive the inner ends of the globular valveca-sings E, which have cylindrical screwthreaded extensions Iitting upon the extensions b', so that they are easily attached and removed. The valves F are hinged to a seat having annular flanges Gr, the interior of which are screw-threaded, and these also tit upon the screw-threaded portion of Z9', so that they may be screwed on or removed. When screwed down and seated, they are locked in place by screw-bolts H, which pass through the flanges G and into the part b.
The valves F have curved extensions f to the rear of their pivot or hinge points, with antifriction-rollers, and these are engaged by springs f', as shown. These springs exert a tension when the valve is opened, so that as soon as the water ceases iiowing through the valve it will be quickly closed and the backward movement of water reduced to a minimum. Hand-holes g are made in the valvechambers E, so that by removing an exterior cap access may be had to the valve for any small repair.
The pipes D and D' are flanged and are bolted to corresponding flanges upon the outer ends of the Valve-chambers, so that if it is desired to obtain access to the interior of the valve-chambersit is only necessary to remove the sections D DQ to then remove the bolts H, and finally to unscrew the valve-seats from the extensions b', and, if necessary, the valvechambers E can be removed in the same manner.V This provides for easy access to all the parts, and if for any reason the pump-cylinder A needs repair or renewing it can be removed from the heads B, and repairs can thus be made with a minimum of labor and material. The interior of the heads B can also be reached from the outside by means of handholes opening thereinto and covered with suitable hand-hole plates. The pl unger consists of two circular heads or disks C and a hub or central portion ol" rectangular form, and the plunger-rod C is secured thereto. Between these heads are the metallic rings C2, made in halves, with angular joints, as shown, and these are held in place concentrically by reason of their fitting within the pump-cylinder. They are forced outwardly to preserve a close Working fit in the cylinder by means of springs c, the inner ends ot which abut against the inner faces of the rim-sections C2 and the inner ends against the rectangular hub or portion, which lies between the heads C C. rIhe angular joints in the piston-ring sections allow them to be separated by the pressure of the spring c, and thus IOO compensate for any wear of the rings and to maintain a tight joint.
In order to pack the piston-rod where it passes through the cylinder-head,l have shown packing-sections of two kinds fitting around the rod. One of these sections is made in quarters or other subdivisions, as shown at l, and these have loops J fixed around their peripheries, and through this an inclosing circular spring K is passed. The ends of this spring overlap, and it is so adjusted that it has a constant tendency to compress the sections I against the rod. The other packingring is made with similar quadrant-sections L, and intermediate between these are radial straight sections M, the inner ends of which fit against the rod, as shown; Upon the outer ends of these sections M are loops J similar to those previously described, and through these loops a spiral spring K, also similar to the one formerly described, is passed. The action of this spring, as before stated, is to force the radial sections M against the plunger-rod. The exterior diameter of the sections L is less than the diameter across the sections M, so that a space is left between the periphery of the sections L and the interior of the spring K. Within this space the spiral springs O are fixed, and the outer ends of these springs press against the surrounding spring K, while the inner ends press against the sections L, and thus force them into the angles between the previously-described sections M. The lowermost of these two sections fitting around the rod C rests upon a rubber or other flexible gasket I), which lies upon the cylinderhead. Above the upper packing-rings is another gasket P, and upon this rests a flanged disk Q; Into this disk screws the gland R, through which the plungerrod C/ passes. The disk Q is secured to the cylinder-head by bolts S, which are screwed into the cylinderhead, and suitable nuts screwing down upon their outer ends compress the gaskets IJ P and the packing-rings I, M, and L, so that no leakage will take place around the plungerrod. The bolts S are the only supports for the packing, and there is no exterior chamber or casing into which these parts are fitted, as in the usual construction of packing.
The pipe-sections employed in this pump are jointed as follows: T is acoupling-sleeve having an interior iiexible and elastic lining, which has beveled orin terior fianges, as shown at t. The inner periphery of these iianges is normally of smaller diameter than that of the pipe-section U which is to be coupled. A section of pipe being slipped into'each end of the coupling T Will be clasped closely by the elastic section t, and thus form a tight joint. In order to hold the parts in place, I have shown a locking-joint of what is termed the bayonet pattern. Right-angledslotsVare made upon opposite sides of the couplingsection T, and the pipe-sections U have upon them lugs NV, which are adapted to slip into the slot V to the bottom. Then by turning one or the other of the parts the lugs lV are moved into the horizontal portion of the slot, and they are then locked in place by means of a key Y, which has a hook end and which engages a clamping-ring X, as shown in Figs. l and 2, and prevents the parts from being separated.
This pump is designed for deep mines and like localities, and the plunger-rod extensions or sections, which are usually made of Wood and square in cross-section, are connected at the ends of the sections as follows: An S- shaped curve is made upon the meeting ends of each of the sections, as shown at c, and the inner surfaces of these curves are lined with metal, with teeth or corrugations m project* ing from the faces of the curved ends along that portion which is approximately parallel with the sides and which extends between the outer ends of the curves. When the sections are put together, these teeth m interlock. The band n is fitted to surround the two sections thus placed together, and by means of a cam 0 and a lever p this band is drawn tightly and the interlocking teeth m are forced together, and the corresponding curves a, which form the continuation, fitting together the rods will stand in line with each other and will be very strongly locked together.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is*
l. A double-acting pump consisting of independent heads in the form of cross-couplings, a detachable cylinder connecting one head with the other, and a pump -plunger adapted to reciprocate within said cylinder, said heads havin glateral extensions, enlarged valve-chambers fitted to said extensions, removable valve-seats fitting said extensions and located interior to said chambers, valves removable with said seats and having tail extensions projecting into the chambers, and springs within said chambers and acting against said tail extensions to `quickly close the valves, and bolts passing through the walls of the enlarged chambers and walls of the valve-seats and detachably fixing the chambers and seats to the extensions of the cross-couplings.
2. In a pump of the character described, a pump-cylinder, the heads in the form of crosscouplings, enlarged valve-chambers adapted to screw upon the head extensions which are transverse to the line of travel of the piston, valve -seats Within said enlarged chambers and also screwing upon said extensions,valves hinged thereto having tail extensions beyond the hinges and projecting into the enlarged chambers and springs carried by the valveseats and engaging said extensions substantially as herein described.
