To @ZZ whom t may concern,.-

Beit known that I, ELIJAH NEFF, a citizen of the United States, residing at Milford, in the county of Kosciusko and State of Indiana, have inventeda new and useful Pump a specication.

This invention relates to pumps for water systems; and it has for its object to provide certain improvements in pumps ot' that character which are employed in connection with storage and pressure regulating devices, whereby means shall' be provided for collecting and storing quantities of water and air, so that the' former can be distributed to the point of use under air pressure.

With these and many other objects in View which will readily appear as the nature of the invention is better understood the same consists in the novel construction, combination and arrangement of parts hereinafter more fullydescribed, illustrated and claimed.

In the accompanying drawingsz--Figure 1 is a side elevation showing the various parts of my improved system in operative position. Fig. 2 is an enlarged end view of the same construction showing several portions of the pump in section, the pressure regulating device beingshown as separated from and at pipe. Fig. 3 is an enlarged vertical sectional view of the main water cylinder foot-valve devices, and the valved plunger moving` therein. Fig. 4 is a similar view of the upper end of the air cylinder and the. plunger moving therein. Fig. 5 is an enlarged detail sectional View of the discharge or delivery plunger head. Y

Referring to the accompanying drawings, A represents the main water or pumping cylinder supported in a suitable position in a vault room'or beneath the ground, and the main pumping cylinder A, is exteriorly threaded at its lower end to receive the lower cylinder head a. The lower cylinder head a, thus removably connected to the main pumping cylinder, is provided with a transverse valve guide @'and an interiorly threaded valve chamber or neck 0,2, extended therebelow and accommodatingafoot valve a3. The tube c, and is coupled to and, supported in roo toot valve a, is providedpwith upper andl lower stems a4, the upper of which moves in the guide ct', and the lower of which moves through the transverse guide B, of the exterorly and interior-ly threaded valve seat b.

head C, through which is designed 'to reciprocate. the elongated plunger tube c, the lower end of which, inside of the cylinder A, is exteriorly threaded to removably receive the upper threaded end of the plunger valve casing or chamber D. The plunger valve casing or chamber D, of the plunger which moves in the cylinder A, is entirely closed, and is provided with an interior transverse valve guide d, which guides the upper stem d', of the plunger valve d2, arranged to work inside of the valve casing or chamber D. The plunger valve d2, is arranged to work Onto the valve seat at the upper inner end of the cylindrical plunger head E. The cylindrical `plunger head. E, is removably threaded into the lower flanged end e, ofthevalve casing or chamber D, and is provided at its upper valve-seat end with the interior valve guide e', to receive the lower valve stem ot' the plunger valve, and is exteriorly anged as at e2, to clamp 'therebetween and the lower tlanged end c, 'of the casing or chamber D, the anged or cup packing disks F, which work tightly against the inner sides of the main pumping cylinder.

The elongated plunger tube c, is extended above the upper head of the main cylinder A,

vThe valve seat b,- removably engages the in'- suiciently far so as to work into the intermediate discharge o'r delivery cylinder G,ar ranged a distance above the main pumping cylinder and adapted to form a chamber to collect the water and air which are-to bedischarged at one and the same time. The intermediate discharge or delivery cylinder is inclosed at its lower end by the stufting box g, to form a packing around the reciprocating Mss position by the approximately T-shaped coupling head g. The coupling head g','is provided, in a line directly above the coupling of the cylinder Gr thereto,with the interiorly threaded coupling neck g2, and the end coupling necks g3, into one of which is threaded the upper end of the vertical supportingrod or pipe H,which is extended to a solid bed so as to provide for a firm support of the entire pumpingdeviees in a steady position. Into the other end coupling neck g3, is threaded the upper end of the pump discharge pipe H', which will be more particularly referred to as receiving both the discharge from the discharge or delivery cylinder G, and the air devices to be hereinafter described. The said coupling head g',is also provided at one side of its center with a partition or diaphragm lz, which directs the discharge from the pump `entirely through the pipe H', and adjacent to said partition or diaphragm with the guide h', through which reciprocates the pump rod I.

The pump rod I, is connected to a wind mill or other suitable source of power and has its lower end move in the intermediate guide bar @extended-laterally from the stuffing box head C, and provided at its ends with the clamps t', which embrace the support I-I, and the discharge pipe H', respectively, thus spacing and holding the opposite portions of the apparatus in their proper position. A clamp 2, is attached to the pump rod I, and to the plunger tube c, intermediate of its ends so as to provide for the suitable reciprocation of theplnnger tube when the wind mill or other power is in operation.

The upper end of the plunger tube c, which works inside of the intermediate discharge or delivery cylinder G, is removably attached to the valved discharge or delivery plunger or piston head J. The discharge or delivery piston or plunger head J, carries the intermediate packing disks j, and the valve j', workingin the casing 3'2, which opens into the cylinder G, and has removably attached to the upper end thereof the plunger rod K, which extends through and 'above the coupling head g', and works inside of the vertical air cylinder L. The valve j', closes on the up stroke of the pump and serves to eject or discharge the water and air therefrom in the manner to be presently described.

The air cylinder L, is threaded at its lower end into the coupling neck g2, at the top of the coupling head g', and has attached tothe -upper end thereof the head M. The head M, `is provided with the central guide m, and the upwardly extended interiorly threaded valve neck or chamber m', which removably receives the flanged inlet plug N. The inlet plug N, is centrally perforated and is provided with the guide n, which receives the upper stem of the inlet valve O, which is normally held onto the plug N, which forms a seat therefor, by means of a spring o, arranged in the neck or chamber m', under said valve, the lower stem of the valve working in the central guide m, of the head M.

Removably coupled to the upper end of the plunger rod K, is the air cylinder plunger P. The air cylinder plunger P, comprises a closed Valve casing or chamber p, having an interior guide p', and removably receiving at its upper end the plunger clamping disk or head p2. The plunger clamping disk or head p2, clamps between the same and the upper flanged end ofthe valve casing or chamber 19, the packing disk 193, and is provided with a perforated guide p4, which receives the upper stem of the plunger valve Q. The plunger valve Q, works inside of the valve easing or chamber p, and is held closed onto the inner end of the head p2, which forms a seat therefor, by means of the valve closing spring q, arranged under the valve on the guide p', which accom` modates the lower stem of the valve. At the lower end of the plunger valve casing or chamber p, and in the upper end of the plunger rod K, is formed the air discharge opening R, which directs the air into the air cylinder L, under the plunger moving therein, so that it, the air, can be forced together with the water out of the coupling head g' into the discharge pipe H.

Now from the foregoing it is thought that the construction and operation of the pumping devices will be readily apparent to those skilled in the art. As the pump rod reciprocates, motion is necessarily communicated to the plunger tube c, which draws the water through the supply pipe b', and the foot valve at the lower end of the main pumping or water cylinder, into such cylinder. As the pumping continues, the water passes through the valved plunger at the lower end of the plunger tube, and up said plunger tube and out of the valved discharge or delivery plunger J, into the intermediate discharge or dei livery cylinder G. At the same time air is drawn into the air cylinder, and is collected, under the same pressure as the water, beneath the plunger moving in the air cylinder so that both the water and air will be discharged and forced under the same pressure through the discharge pipe H', thus providing an efficient combination pump for simultaneously collecting and discharging water and air. The discharge pipe H', is provided near its lower end with the stop cock S, the funption of which will presently appear, and is coupled at such end by means of the horizontal coupling liange s, onto the outer fianged end of the off-standing tank supply pipe s', said coupling flange s, being extended laterall)7 to embrace the upper end iof the supply pipe b', as well as the supporting rod` H, so as to additionally strengthen the apparatus. The tank supply pipe s', leads into the bottom and one end of the cylindrical storage tank T. The cylindrical storagetank T, is supported on the end supporting legs t, arising from a suitable base t', and has the 512,737 Y v e opposite heads thereof connected vby a series of longitudinally arrangedstrengthening bolts U. The longitudinally arranged strengthening bolts U, extend through the interior of the tank and are threaded at each end to receive the clamping nuts u, working against the copper washers u', which fit against the opposite heads of such tank at points in from the edges of the heads which are riveted at their edges to the body of the tank. The longitudinally arranged strengthening bolts U, also accommodate the spacing sleeves u2, the opposite ends of which bear against the inner sides of the opposite heads of the cylindrical tank, so that a construction is completed which prevents the oppositeheads of the tank-from either contracting or expanding,as the pressure may be relieved therefrom or increased therein, as will be readily apparent. The water and airis pumped intothe storageftankwhen the windmill or other power is in operation, so that the air which is displaced' into the top portion of the tank by the heavier water, will always Vbe under sufficient compression -in such tank, so as to 'torce the water out-through the distributing pipe ua, to the point of use, such distribution being regulated by suitable valves and line of piping. The level or height of thewater in the storage tank may be observed on the water glass or gage V, at one end of the tank, and the pressure in such tank indicated by means of theindicator -W, attached to the vtop of the tank. When the power is not in operation the stop cock S, may be turned so as to hold the waterin the tank without loss of pressure.

Inl-order to control the power operating the pumping devices, I employ a suitableY power regulating device which I shall now proceed to describe. A vertical pressure cylinder X, is coupled by means-of the valved coupling pipe to the tank supply pipe s', at a point Vintermediate of its connection with the tank T, and the discharge pipe H. The cylinder accommodates the sliding piston head an', attached to the lower inner end of the piston rod Y. The pistonrod Y, works through the upper closed endpor head y, of the pressure cylinder, and has adjustably attached to its upper end the weighty', which normally tends to force the piston head at', to the bottom of the cylinder X. An off-standing guide pulley Z, is attached to the upper head y, of the cylinder X, and forms a guide for the power regulating rope or wire a, passing therearound and attached at one end to the weight y', and at its other end to the windmill or other power so as to throw the same in and out of gear in anysuitable manner. Now itwill be apparent to those skilled in the art, that,'as the pressure in the storage tank T, increases beyond the point at which it is advisable to sustain the pressure, the piston in the 'pressure cylinder will be forced upward, thereby lifting the weight y', and pulling down on the cord creases, the weight at the upper end of the piston rod will lower the piston in the pressure cylinder, and relieve the rope or wire, so

. as to allow the power to start again, so that pumpingV will commence. A safety valve Z', is attached to the connection fr, so y as to relieve the tank of sudden increase in pressure.

From the `foregoing it is thought that the construction, operation and many advantages of the herein-described apparatus will be readily apparent to those skilled in the art, and I will have it understood, that changes in the form, proportion and the minor details of construction asembraced within the scope of the appended claims, may be resortedto without departing from the principle orsacri- Iicing any of the advantages of this invention.
