PHILIP A. MYERS,

BROTHER, OF

OF ASHLAND, OHIO, ASSIGNOR TO F. E. MYERS AND ASHLAND, OHIO, A OOPARTNERSHIP.

PUMP.

To all whom it may concern:

Be it known that I, PHILIP A. MYnns, a citizen of the United States, residing at Ashland, in the county of Ashland and State of Ohio, have invented certain new and useful Improvements in Pumps, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to. pumps, and is, in a sense, in the nature of an improvement upon what is set forth in Letters Patent No. 574,441, granted to me January 5, 1897.

The objects of the present invention are chiefly to provide an improved construction for transmitting motion from the pumphandle to the pump-rod, which will permit said rod and the piston to move in a direct line without swaying from side'to side; to provide means whereby the rod may be properly guided and supported with a minimum of friction, while the gearing connecting the handle and rod is properly guarded and protected; to provide aconstruction by which the handle may be readily adjusted in length to adapt it to wells of different depths so as to proportion the leverage to the work, and to provide means whereby the bracket or extension of the standard which supports the head and handle may be adjusted relatively to the standard to facilitate the assembling of the parts in proper relations to each other.

To these and other ends my invention consists in certain novel features, which I will now proceed to describe, and will then particularly point out in the claims.

In the accompanying drawings, Figure 1 is a side elevation'of a pump embodying my in vention in one form. Fig. 2 is a view of the upper part of the same, on an enlarged scale, and chiefly in central vertical section. Fig. 3 is a detail rear elevation illustrating the adjustable connection between the standard and its extension or bracket. Fig. 4 is a detail sectional viewtaken on the line w a; of Fig. 3 and looking in the direction of the arrows, and Fig. 5 is a detail plan section taken on the line y y of Fig. 1 and looking in the direction of the arrows.

In the said drawings, 1 indicates the pumpstandard, adapted, as in my prior Letters Patent hereinbefore referred to, at the upper end of its body, as indicated at 2, to receive and support the head 3, provided with a Specification of Letters Patent.

spout 4, and adapted to be turned relatively to the standard-body to move the spout to any desired position around said standard. Saidstandard is also provided at one side with the upwardly-extending arm 5, having threaded apertures6 to receive the clamping screw-bolts 7, by means of which the extension or bracket 8 is secured to the arm 5. The lower portion of the extension or bracket 8 is recessed, as indicated at 9, to receive and fit upon the arm 5 and is provided with vertical slots 10, through which the clamping bolts 7 pass, so that the extension or bracket 8 may be adjusted vertically relatively to the arm 5 and standard 1. Said extension or bracket carries the sleeve or ring 11, which receives and supports the upper end of the head ,3, which fits therein so as to be capable of rotation. The extension or bracket 8 extends upward above the point where the ring 11 is located and is bifurcated at its upper end and apertured to receive a bearing-pin 12, which serves. as a fulcrum for the handle 13.

segment 14, concentric with the bearing-pin 12 and meshing with a rack 15, secured to or formed on the pump-rod 16. The construction of handle which I prefer is that shown, in which thebody of the handle (indicated at 17) is constructed of ordinary wrought-steel pipe, threaded externally at its extremities, as indicated at 18. The gear-segment 14 is provided with a socket 19, internally threaded to receive the upper end of the pump-handle, while the terminal knob 20 at the other end of the handle is similarly threaded for connection thereto. By reason of this construction the body of the handle may be readily made of any desired length to adapt the leverage thereof to the power required when the pump is used in connection with wells of different depths,- the nature of the structure being such that the necessary material and labor to substitute a handle-body of the desired length or to change the length of said body can be readily obtained at a minimum expense.

Near the upper end of the bracket or extension 12 there are provided forwardly-extending arms 21. In these arms there is removably mounted a j ournal-pin 22, on which is mounted a roller 23, which bears against the front face of the pump-rod 16 and supports the same against the thrust of the gearsegment 14 against the rack 15 on the rear This handle is provided with a gearside of said pump-rod. As a further means for supporting and guiding the pump-rod independently of the gear-segment and roller I provide above said roller a guide 24, embracing the pump-rod in the manner shown in detail in Fig. 5. This guide is supported from the arms 21 by means of arms 25 and is also supported by means of a guard or shield 26, which extends over and in'closes the upper part of the gear-segment 14, said guard being mounted on the upper end of the extension or bracket 8. This guard, in conjunction with the

arms

21 and 25 and the guide 24, completely incloses and protects the intermeshing portions of the gear and rack, preventing injury thereto by the accidental introduction between them of any foreign body and at the same time preventing injury to the operator by rendering it impossible for him to get his fingers or clothing caught between the gear and rack.

It will be seen that .by the employment of a gear-segment on the pump-handle meshing with a rack on the pump-rod the swaying from side to side of said rod and the piston connected therewith, arising from the usual link connection between these parts, is done away with, the strain or thrust on the pumprod, so far as there is any, being always in the same direction and being met by the roller in such a way as to prevent lateral deflection of the rod without undue frictional resistance, while the rod is guided and supported independently of the gearing and roller by the guide provided for that purpose. It will be understood that these pumps are frequently employed in connection with a windmill, so as to be operated either by hand or by power derived from the mill. In this latter case the handle and gear-segment may be entirely re moved from the pump by first removing the bearing-pin 12. When this has been done, the pump-rod 16 is then properly guided, notwithstanding the removal of the gear-segment, the guide 24 providing a bearing for the pump-rod on the rear side thereof by the contact with said guide of the teeth of the rack, the guide being of sufficient length to prevent the teeth from interlocking therewith or catching thereon. Thus when the handle and gear-segment are removed and the windmill is connected to the pump-rod to reciprocate the same said rod may be properly guided and supported while the windmill is operating the pump. The gearing is so guarded as to protect it and the operator.

body, whereby,

Provision is made for readily applying a handle of a length such as to give a leverage pro- I do not wish to be understood as limiting myself strictly to the precise details of construction hereinbefore described and shown in the accompanying drawings, as it is obvious that these details may be varied without departing from the principle of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a pump,

a standard having a lateral upwardly-extend ing arm, an extension or bracket fitting and vertically adjustable on and a head rotatably supported between said ring or sleeve and the top of the standardbody and provided with a spout, the adjustment of said extension permitting the distance between the ring and the top of the standard-body to conform to varying lengths of the head, substantially as described.

2. In a pump, a standard having an upward extension, a head provided with a spout and rotatably mounted in said standard-body and extension, a pump-rod working throu h said head and provided witha rack above t e same, the extension having means for guiding and supporting said pump-rod above the head, and a gear-segment journaled on said extension, meshing with the rack and provided with a handle, said extension being very tically-adjustable relatively to the standardwhen said extension is adusted to receive heads of varying length, the gear-segment and pump-rod rack are conformably adjusted, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
