SPECIFICATION forming' part Of Letters Patent N0. 680,098, dated August 6, 1901.

Application filed May 16, 1900. Serial No. 16,865. (No model.)

To all whom, it may concern,.-

Beit known that we, WILLIAM C. WHITTA- KER and WALTER V. TURNER, citizens of the United States, residing at Raton, in the county of Colfax and Territory ot' New Mexico, have invented a new and Improved Pump, ot'which the following is a full, clear, and exact de scription.

The object of the invention is to provide a 1o new and improved pump which is simple and durable in construction, very effective in operation, and arranged to work uniformly and either as a single or double acting pump, the operating power in either case being equally divided between the up and down strokes of the piston.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then zo pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a sectional side elevation of the improvement with parts in position for single action. Fig. 2 is a side elevation of the locking device for the auxiliary piston. Fig. 3 is 3o a plan view of the valve-seat for one of the suction-valves. Fig. 4 is a sectional plan view of the main cylinder. Fig. 5 is a side elevation, partly in section, of a windmill;

and Fig. 6 is a section on line 6 6 of Fig. 5.

The improved pump is provided with a cylinder A, extending into the water contained in a well B, and in said cylinder reciprocates a piston O, held on an upwardly-extending piston-rod C', adapted to be connected at its 4o upper end O2 to the pump-rod X of a windmill or other motor, a Windmill being shown in the drawings for imparting' a reciprocating motion to the piston C. The piston-rod O may also be actuated by hand, and for this purpose said piston-rod is pivotally connected near its upper end with a hand-lever D, fulcrumed on a link E, pivoted to an arm F', attached to a stand F, secured to the cover B' of the well B. The upper end of the arm F also serves as a Guide or bearinff for the o .l l o o wpiston-rod C On the lower end of the cylinder A is secured a suction-cap G, and on the top thereof is secured a cap H. The lower cap Gcontains a valve-seat G for a suction-valve l, used only when the pump is to be double-acting, as hereinafter more fully described, the lower end of the stem I of said valve being provided with a collar l2, resting on an arm J, pivoted at J to the cap G,and connected at its free 6o end with a rod J2, extending upward through the well and the cover B thereof, as is plainly shown in Fig. l, said rod J2 being provided near its upper end with a ring J3, adapted to hook upon a hook J 4, carried by the stand F. The extreme upper end of the rod J2 isv connected with one end of a lever J5, fulcrumed on a suitable support, and connected at its other end by cord or rod J6 with the governor X2 on the windmill'. The cord or 7o rod J6 is secured to a collar X3 on a sleeve X4 on the pump-rod X and connected with the; governor by the cord X5, as shown in Fig. 5. The governor, however, forms no part of the present invention. The ring J3 and hook J4 75 `are only used when the rod J2 is to be controlled by the operator-that is, locked in an uppermost position-the valve I being off its seat at the time the pump is to be used as a single-acting pump; but when the rod J2 is 8o connected with the governor then the position of the valve I is controlled by said gov-v ernor according to the force of the Wind. Thus in a light wind the valve I will be lifted olf its seat by the governor, so that the pump is single-acting; but in a heavy wind the governor will pull on the rod Ji and swing the lever J5, so that the rod J2 moves downward, and the pivot-arm J swings in a like direction to allow the valve I to seat on its seat 9o G', and thereby render the pump double-acting, as hereinafter more fully described. The collar I2 on the lower endv ot the stem I limits the upward or opening movement of the valve I. l g5 The cap G is provided with a passage G2, leading to a suction-passage A, arranged at one side of the cylinder, a valve-seat H being on the topof said passage A', a valve K being on the top of said seat and opening into the lower portion of the upper cap H. This lower portion of the cap H connects with the upper end of the cylinder A, so that when the piston C moves downward water is drawn into the lupper end of the cylinder by way of the cap G, the passages G2, A', the valve K, and the Vlower portion of the cap H. The lower end of the cylinder A is connected by the top part of the lower cap G, and the valveseat G3 for the valve K' is connected with a passage A2, located on the side of the cylinder A opposite the passage A', as is plainly shown in Figs. l and 4, and the upper end of said passage A2 connects by a passage H2 in the cap H with a discharge-pipe L, extending vupward in the well B from the top of the cap H. The upper and lower portions of the cap H are separated by a valve-seat H2, on which is adapted to be seated a discharge-valveN, mounted to slide loosely in the stuffing-box C3 for the piston-rod C' and limited in its upward movement bya collaror nut on the said stufngbox.

The upper end of the discharge-pipeL terminates in a cap O, from the middle of which leads an auxiliary cylinder P, andfrom one side thereof extends an air-chamber Q, and from the opposite side extends upwardly the outlet-pipe L' for carrying the water to a suitable place of discharge. In the outlet-cylinder P is mounted to travel a piston R, having a hollow piston-rod R' and through which extends loosely the piston-rod O', the upper end of said hollow piston-rod R' being adapted to be engaged by a collar C4, carried on the piston-rod C', so that when the latter moves downward said collar C4 engages the piston-rod R and pushes the latter and its piston R in a downward direction. l/Vhen the piston C moves upward and the dischargepipe L and cap O are iilled with water, then the water lifted in said pipe and cap exerts a pressure on the under side of the piston R, so as to move the same upward in the cylinder P. Thus the downward stroke of the pis-- ton R is by the force of the piston-rod C', and the upward movement of said piston is by the pressure of vthe water lifted during the upstroke of the piston C.

Near the upper end of the hollow pistonrod R' is a pin R2, adapted to be engaged by the arm S' of a bell-crank lever S, connected with the rod J2, so that when said rod J2 is moved downward by the action of the governor or by the operator then aswinging motion is given to the bell-crank lever F to move the same into the position shown in Fig. 2 'to cause the arm S' to move over the pinR2, so as to lock the piston-rod R' and the piston R in a lowermost position. l/Vhen this takes place, the piston R remains stationary in its cylinder, and the pump is now adouble-acting pump, as above mentioned.

The operation is as follows: When a reciprocating movement is given to the piston C 'at the timethe valve I is lifted oits seat and the piston R is in an unlockedposition, then during the downstroke of the said piston water is drawn into the upper endrof the cylinder A by way of the cap G, the passages G2 A', the valve K, and the lower portion of Y the cap H, and during the upstroke of said piston the previously-drawn-in'V waterlin the upper end of the cylinderis forced out'through the'valve-seat H2 past the valve N, so that the water passes through the upper portionof the cap H into the discharge-pipe L. During a repetition of this described reciprocating movement of the piston O the water rises in the cap O and the outlet-pipe L' and finally passes from the latter to a suitable place of discharge. When vthe Water is lifted in the pipe L and cap O during the upstroke of the piston C, then the water presses on the piston R, and thus causes an upward movement of the same in the cylinder P. The cylinder P is located approximately an equal distance from the water-level in the well and the dischargewater from the pipe L', so that upon the next downstroke of the piston C the piston R is moved with it by the action of the collar C4 on the upper end of the piston-rod R', so that the said piston R now forces the Water up in the pipe L' to a place of discharge. lFrom this it is evident that the water is lifted halfway bythe piston C on its upstroke and forced the other half of the way by the piston R during the down or suction stroke of the piston C. Thus only approximately one-half of the power is required for lifting water a certain distance on the upstroke and the other half of the power is required on the downstroke'. From this it is evident that if the device is connected to a windmill the latter is free to run very uniformly, owing 'to the equal power required forworking the pump on both the up and down strokes. When the operator removes the ring J2 from the hook J 4 and pushes the rod J2 downward, orthe said rod is pushed downward by the action of the governor, as above explained, then the valve I moves to its seat, and at the same time the bell-crank lever S is swung over to lock the piston-rod R' and the piston R in a lowermost position in the auxiliary cylinder P. The reciprocating movement of the piston O and the cylinder A causes a drawing of the water into the upper end ofy the cylinder by way of the passages G2 A' and the valve K during the downstroke of said piston, as previously explained, and during the upstroke water is drawn in through the cap G, valve-seat G', and the valve I into the lower end ofthe cylinder. During the downstroke of the piston C the previously-drawn-in water at the lower end of the cylinder is forced through the valve-seat G3, past the valve K', into and through the passages A2 H2 to finally pass into the pipe L, cap O, and outlet L'.' During the upstroke of the piston C, the water previously drawn into the upper end of the cylinder is discharged into the pipe yL by way of ICO IIC

the seat' H3 'and' the valve N, as previously explained. From the foregoing it is evident that a continuous flow of water is obtained as the pump Ais now double-acting and approximately the same power is required on Ithe downstroke as well as on the upstroke of the piston C.
