PUMP-HEAD.

SPECIFICATION forming part of Letters Patent No. 433,989, dated August 12, 1890.

' Application led February l2, 1890. Serial No. 340,178. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL lV. MARTIN, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio,

have invented certain new and useful Improvements in Pump-Heads, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to certain new and use- 1o ful improvements in pump-headsv The object of my improvements is to construct a pump-head in a number of parts or sections, instead of one entire piece, and to screw or otherwise conveniently fasten them together, so as to form practically one piece when completed, thus admitting of using a number of small cores, instead of one large core, and of furnishing better and sounder castings. Furthermore, bymaking the pumpzo head in sections if any part is injured or broken in transportation or use after purchase it is only necessaryto order a duplicate of the section injured, instead of the whole pumphead, thereby resulting in a very material sav- 2 5 ing to the purchaser.

In the accompanying drawings, forming a part of this specification, and in which like reference-letters indicate corresponding parts, Figure l represents a side elevation` of my 3o pump-head wit-h its handle and handle-standards mounted thereon, and Fig. 2 a vertical section on the line a; 00 of Fig. l.

The letter A designates a base having a iiange by which the base is bolted or other- 3 5 wise secured to a suitable foundation. A vertical annular portion or neck B, of less diameter than the upper portion of the base, extends upward therefrom and is screwed or otherwise secured to the lower portion of a body- 4o section O, preferably having open-work on opposite sides. Ihe bearing-surfaces between the base and the body-sections are formed at D, and are farther from the axis than the screw-threaded portions, by which the sections 4 5 are preferably fastened together, and also are situated in another plane. By this arrangement of the bearing and the securing portions of the sections a iirm connection between the same is obtained, and the stiffness is much 5o increased by the bracing eect of a wider footing on the .base-section than could be conven- Vbeing formed by an annular portion or neck F, screwed into the upper portion of the bodysection, and by matching bearing-surfaces G G on the body and spout sections, respectively, that act on a yielding annulus or cushion II, located between them. This cushion is not a packing-ring, for it may be made of any yielding substance. By means of this cushion the spout-section can be turned more or less to match in position with the body-sec- 7o tion when desired, while at the same time a firm connection between the sections is secured. A cushion is not used between the base and the body-sections, because it is preferred to make the base symmetrical, and 7 5 hence it makes no dierence what may be the final position of the base. A handle-standard I, carrying a handle and pump-rod, is mounted on the upper portion of the said section E and secured in its desired position by a set-screw 8o K, bearing in the groove L, as is usual. Thus it will be observed that by my improvements the pump is obtained in sections and does not differ in ordinary appearance when set up from a head cast in one piece, while it may be readily dismembered whenY a section is broken and said section easily duplicated and replaced at a slight cost of time and money to the owner, compared with what he would be required to expend if the head were in one 9o piece. The connections are so hidden that the joints in no way lessen the neat appearance of the head. Furthermore, the castings forming the head are sounder when the head is made in sections and the loss from imperfect castings is less, because the iron has not time to chill in pouring, as is the case when along thin shell is cast in one piece, and a defect in one portion of which condemns the whole head to be broken up and recast; also, roo the smaller cores required for the sections are cheaper to make and easier to mold and remove from the section than the one large eoie used when the'head is cast in one piece. These l advantages have been observed in the praetieal carrying out of my above-described mproveinents.

Having thus fully described Iny invention, what I claim as new, and desire to secure by Letters Patent, ist In a pump-head, the eornbination,with the hase A, having an eXterorly-threade'd neck B and an enlarged bearing-surface D, a bodysection C, having an interiolly-threaded apertuie and a Corresponding enlarged surface at its lower end, and having at its upper end an interiorly-threaded aperture and shoulder, and a spout-section E, having.` an exteriorlythreaded neck F and a corresponding shoulder.

In testimony whereof I a'ix my signature in presence of two Witnesses.
