Specification of Letters Patent.

Patented Aug. 10, 1909.

Application filed June 8, 1998. Serial No. 437,280.

To all whom it may concern:

Be it known that I, PHILIP A. MYERS, 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 VVorking-Heads fol,"

Power-Pumps, of which the following is a specification, reference being had therein to the accompanying drawings. a

Ihis invention relates to working heads for power pumps and the object of the invention is to provide a working head of this character which will permit the removal of the working parts of the pump without disconnecting, or in any way interfering with the discharge pipe or operating gearing for the pump; to so construct such a working head as to render the same water-tight at all points; to so support the operating gearing thereon that it will not interfere with the removal of'the working parts; and to provide such a working head which will be simple in its construction and operation and which will be strong and durable, the parts of which will notbe liable to become disarranged.

With these objects in View my invention consists in certain novel features of construction and in certain parts and combinations hereinafter to be described, and then more particularly pointed out ii -the claims.

In the accompanying drawings, Figure 1 is a front elevation of a working head embodying my. invention; Fig. 2 is a vertical sectional view, taken centrally through the same; Fig. 3 is a transverse sectional view, taken on the line at w of Fig. 2; Fig. 4 is a sectional detail View of the upper portion of the base; Fig. 5 is a detail plan View of the base; Fig. 6 is a detail view of the cross head; and Fig. 7 is a detail view of one of the bearing blocks.

Inthese drawings I have illustrated the preferred form of my invention and have shown the same comprising a hollow base 1 which mav be secured upon a support or platform of any suitable character and which is provided at a point between the upper and lower ends thereof with an inwardly extending projection or annular flange 2, upon which is mounteda supporting ring -3 adapted to support the suction pipe-4, the

ring and upper end of the suction pipe being preferably screw-threaded to enable the same to be readily connected to and disconnected said closure.

from each other. The flange 2and ring 3 divide the hollow base 1 into two parts and form above the ring 3 a chamber 5 which is provided with a closure 6 adapted to be secured to the base by bolts 7 extending through the closure and through a flange 8 formed on the upper end of the base, a packing being inserted between said flange and This chamber 5 is provided with an outlet 9 which is preferably formed integral with the base 1 and is adapted to have the outlet pipe 10 secured thereto. In order that there may be no leakage between the chamber 5 and the-lower part of. the base, it is desirable that a water-tight oint should be formed between the flange 2 and the supporting ring 3, and, to this end, I have inserted a packing 11 between the ringand the flange and have. provided the ring with an upwardlyextending ap'ertnred collar or cage 12 which, in the present instance, is formed integral therewith and terminates a short distance below the closure for the upper end of the chamber 5. Adjustable clamping members are carried by the closure 6 and are adapted to engage the upper edge of the collar 12 and thereby clamp the ring3 tightly upon theflange 2. This clamping means preferably comprises a series of bolts 13 threaded into apertures in the closure 6 and having their lower ends adapted to engage the upper edge of the collar and their upper ends squared or otherwise provided with a wrench grasp 14, thus enabling the same to be turned down tightly upon the collar 12. A suitable cap or hollow nut 15 is mounted 'upon that portion of the bolt 13 which extends beyond the closure 6, and a packing 16 is inserted between said. nut or cap and the upper side of the closure. Thus, by tightening down the cap, a water-tight connection is made between the cap and the closure and all leakage prevented about the bolt 13, and further, the nut or cap 15 serves as a janibnut which tends to prevent the movement of the bolt 13 in theclosure 6. The pump rod 17 which carries at its lower end a water liftingdiavicc, such as the piston 18, and has connected thereto the Valve 19, extends upwardly through the closure 6 and is 0011- nected at its. outer end to suitable operating, mechanism. The closure is preferably provided with a packing box, through which the rod extends and which comprises acupsha-ped depression or gland 20 formed in the v the same in two closure 6 and having an aperture 21 at its lower end, through which the pump rod extends. l acking material 22 is inserted in the cup-shaped gland about the rod 17 and a cap 23 is inserted in the upper end of the receptacle about the rod 15 to secure the packing firmly in place. a

Guide rods 2% are secured to the base 1, preferably by rigidly mounting the same in suitable apertured lugs 25 located on the opposite sides of the closure (5. These guide rods are adapted to engage the opposite ends of a cross head 26 which is provided with suitable guideways to receive the same and to which the pump rod 17 is secured at a point between said guide rods. To this end, the cross head is provided, near its opposite ends, with apertures 27 which form guideways for the guide rods 24: and near its center with an aperture 28 within which the pump rod 17 is secured, preferably by providing the same with. an enlarged head 29 and a shoulder 30 adapted to engage the opposite edges of the cross head and prevent movement of the pump rod Within said aperture. In order that the cross head may be readily attached to and removed from the guide rod and pump rod I prefer to form pieces by dividing the same along a vertical plane, taken longitudinally of the cross head and near the center of the several apertures therein. This line of division extends outwardly to the face of the cross head just beyond the apertures 27 at either end of the cross head and thus divides the cross head into a main portion 32 and a removable portion 33 which is secured to the main portion by means of bolts 34, and, inasmuch as the line of division extends through the apertures 27 and 28 therein, it will be apparent that upon separating the two partsof the cross head that the same can be entirely removed from the guide rods and the pump rod.

The main portion of the cross head is provided near its outer end with bearing lugs or wrist pins 35, upon which are journaled the upper ends of the connecting rods 36, the lower ends of which are journal'ed upon suitable crank pins 37 eccentrically mounted on the gear wheels 38. are mounted upon the base 1 in any suitable manner, preferably by securing the same to the opposite ends of a shaft 39 which is journaled in suitable-bearings 40 upon the base 1, these hearings being preferably formed in the inner ends of brackets 41 se cured to the base near the opposite sides thereof. In order to secure these brackets firmly to the base I prefer to provide the base with supporting plates 42, which, in the present instance, are cast integral therewith and are of such a shape and are so arranged as, to form a supporting surface for the brackets 41 which are detachably secured These gear wheels" thereto by means of bolts 43. The gears 38 are rotated by means of pinions 44 mounted upon a shaft 45 which is journaled at a point removed from the base 1 and provided with suitable driving gears, such as the pulleys 46. The shaft a5 is preferably mou nted in bearings 47 formed in the outer ends of the brackets 41 and has the pinions 4-4 secured thereto on the outer sides of said bearings and the driving pulley l0 and an idler l9 mounted thereon between the brackets. Thus, it will be seen that the operating gcaring is so supported on the base 1 as to be entirely out of alinement with the upper end thereof and that by removing the closure 6 and separating the cross head from the guide rods and pump red, the entire working parts of the pump may be removed therefrom without interfering with any parts thereof other than those mentioned. These working parts, in the present instance, include not only the pump rod and plunger 18 and valve 19 which are connected to the pump rod, but also the suction pipe l and the parts carried thereby, all of which may, if desired, be removed through the upper end of the base without interfering either with the pipe connections or the belting or operating gearing of the pmnp.

In pumps of this character itis very desirable that the working head should, be what is known as a low-down head, i. 0., a head having a very short base and having the operating mechanism located close to the supporting surface, thus not only economizing space and material, but bringing the strain close to the support and practically eliminating the tendency of the base to tilt and work-loose from its fastenings. It will be observed that I have accomplished this result and have provided a low-down base having the shafts of the operating mechanism supported on one side thereof and in substantially the same horizontal plane as the chamber 5, z. 6., in a plane extending between the closure (3 and supporting ring 3, having the operating mechanism operatively connected to the pump rod at a point above the base. It will also be observed that the construction of the packing box or gland and its location relatively to the supporting ring 3 is such as to afford a guide which will maintain the pump rod in a position central of the suction pipe.

It will be apparent from the foregoing description that I have provided a working head of this character which will, as stated, permit the removal of all the working parts without the dislocation of or interference in any manner with the discharge pipe or the belts or other operating gearing; that thisworking head is of a water-tight construction, preventing all leaking between the several parts thereof; and further, that the construction and operation of the working head and its operating mechanism is of a simple character which -is not liable to be-.

come disarranged or inoperative andwhich is of a strong, durable naturecapable of withstanding a large amount of strain and heavy usage.

I' wish it to be understood that I do not desire to be limited to the details of construction shown and described, for obvious modifications will occur to a person skilled in the art.
