TRIPLE-PISTON DEEP-WELL PUMP.

SPECIFICATION forming part of Letters Patent N0. 627,315, dated J u 20, 1899.

Appiimiou fiied Augtst'zz, 1898.

To all whom t may con/007121,:

Be it known that LWILLIAM CALVIN VOOD- WARD, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Triple-Pis? ton Deep-Well Pumps; and I do declare the following to Vbe a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improved triplepiston pump for deep wells; and the object is to provide a pump of this character whereby by myimproved construction the efiiciency will be increased by dividing the load in such a manner that with the same expenditure of power a greater waterrcapacity will be attained in a given period of time than has heretofore been the case in pumps employed for this purpose.

To this end the novelty consists in the construction, combination, and arrangement of the device, as will be hereinafter more4 fully described, and particularly pointed out in the claims. p

T-he accompanying drawings show my invention in the best form now known to me; but many changes in the details might be made within the skill of a good mechanic without departing from the spirit of my invention as set forth in' the claims at the end of this specification.

The same reference characters indicate the saine parts of the invention.

Figure 1 is a front elevation of my improved pump. Fig. 2 is an enlarged side elevation of the pump-head. Fig. 3 is a similar view of the same, taken at a right angle to that shown in Fig. 2. Fig. 4 is a top plan View of the pump-head. Fig. 5 `is an enlarged Vvertical section of the same. Fig. is a similar view taken at a right angle to that shown in Fig. 5. Fig. 7 is a horizontal section on the line 7 7 of Fig. 2. Fig. 8 is a similar view Fig. 9 is a similar view taken on the line 9 9 of the same figure. Fig. is an enlarged vertical section of the pump barrel or cylinder. Fig. 11 is a similar view of the triple-piston rods. Fig. 12 is a cross-section on the line 12 12 of Fig. 11.

Serial No. 6895261. (No model.)

Fig. 13 is a diagrammatic View illustrating the relative positions of the triple pistons.

1 represents the pump-head, which is rec tangular in form and is provided on three sides with the horizontal radiating bearing brackets 2, 3, 3', and 4, in which are jour naled the shafts 5, 6, 6', and 7.

8 denotes the hood or cover for the head, and it is formed with the integral bearing caps 9 9 9, by means of which it is removably secured to the alined .bearingbrackets onthe head by the bolts 10 10. Independent bear= ing-caps 11 11 are also secured to the outer ends of the bearing-arms to afford the proper protection for the radial shafts journaled therein.

12 represents the upper section of the well casing or tube, and it is provided with the lateral outlet or discharge pipe 13 and with the stuffing-boxes 14 14 14, through which the piston- rods 15, 16, and 17 pass.

18 denotes a miter-gear fixed onthe inner end of the shaft 5, and its face carries a wristpin 19, from which a connecting-rod 20 extends upwardly to a cross-head 2l, one end of which is formed with a guide-sleeve 22, which encompasses a vertical guide-rod 23, xed in the hood 8, while its other end is formed with a collar 24, which encompasses the piston-rod 15, to which it is adjustably secured in any suitable manner, and of course it will be understood that a rotary motion of the gear 18 will impart a vertical reciprocating movement to the Vpiston-rod 15. A similar miter-gear is fixed to the inner end of the shaft 6 and meshes with the gear 18, and it is providedwith a wrist-pin 2G, from which a connecting-rod 27 extends to a similar crosshead 28, one end of which carries a guidesleeve 29, encompassing the guide-rod 30, while its opposite end is fixed to the pistonrod 16, as in the iirst instance. A corresponding miter-gear 31 is fixed to the inner end of the shaft 7 and meshes with the gear 25, and from its wrist-pin 32 a connecting-rod 33 extends to the cross-head 34, which, as in the previous instances, has one end encompass'- ing the guide-rod and its other end secured to the piston-rod 7 The back face of the ruiter-gear 25 is formed IOO with an annular internal spur-gear 36, which meshes with a pinion 37 on the shaft 6, j ournaled in the bearing-bracket 3 and by means of which the three miter- gears 18, 25, and 3l are driven to simultaneously reciprocate the piston- rods 15, 16, and 17. These piston-rods extend in the order shown in Fig. 12 through the Well-tubing 38, holding an approximately triangular position with relation to each other, but are brought together on a common axis at the pump-cylinder 39 in a manner to be now explained.

The lower end of the piston-rod 15 terminates in a guide-yoke 40, to which is fixed a depending sleeve 4l, through which the piston-rod 16 passes, and also with a parallel guide-orifice, through whichthe piston-rod 17 extends. The lower end of the pistoni-rod 17 terminates in a guide-yoke 42, to which is fixed a depending sleeve 43, which encompasses the sleeve 41 and the piston-rod 16,' and to the lower end of the rod 16 the piston 44 is fixed, while the piston 45 is fixed to the end of the sleeve 41, which is a continuation of the piston-rod l5, and the piston 46 is fixed vto the end of the sleeve 43, which is a continuati'on of the piston-rod 17 .f These pistons 44, 45, and 4G are all similar' in construction, and each is provided with a suitable valve, which lifts as the piston descends and falls as the piston rises in the manner common to this class of pump-pistons.

By referring to the diagram Fig. 13 the relative course of travel of the pistons will be understood. The circumference of the circle represents the travel of the wrist pins or cranks, which are set at one hundred and twenty degrees apart, which would be about ten and one-third (10%) inches from center to center on a twelve (12) inch stroke.

With a single-piston pump of the same stroke the column of Water will be raised twelve (12) inches each revolution, and with a double-piston pump the column of water will be raised twenty-four (24) inches, and which is the present raising limit; but by my arrangement of the triple pistons one revolution will raise thecolumn of water a height equivalent to three (3) times the distance between the centers of the crank-pins, (104x 3 31,) which is thirty-one (31) inches, a gain of seven inches in the lift at each revolution over the best effective work of the doublepiston pump under the same conditions.

Having thus described my invention, what I claim as new and useful, and desire to secure by Letters Patent of the United States, is-

' l. In a lifting-pump, the combination with a single pump-cylinder, a triple set of valved pistons axially mou ntedy Within said cylinder, of a triple setof intermeshing miter-gears, means for operating said gears and a series of piston and connecting rods independently connecting each gear with its respective piston, substantially as and for the purpose set forth.

2. In a lifting-pump, the combination of a single pump-cylinder, a triple set of valved pistons axially mounted Within said cylinder and a corresponding` triple set of intermeshing gear-wheels, independently connected to their respective pistons, and means for simultaneously rotating said gear-wheels, so as to independently reciprocate said pistons,sub stantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing Wit- UGSSQS.

WILLIAM CALVIN WOODWARD.
