To aZZ whom t may concern;

Be it known that I, WILLIAM N. STARR, a citizen of the United States of America, residing at Ashland, in the county ofAshland and State of Ohio, have invented certain new and useful Improvements in Pumps; and I do hereby declare the following to be 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, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to certain new and useful improvements in force-pumps, and relates more particularly to that class which are suspended in the well,and in which the cylinders are located to one side of the pump-stock; and it consists in the construction, combination, and arrangement of the parts, as will be hereinafter fully set forth, and specifically pointed out in the claims, whereby I provide a forcepump which is simple, cheap, and effective, and which shall possess great strength and durability, in which the danger of leakage from imperfect joints is obviated,and in which several of the parts serve more than a single purpose, and which can be readily put together, and as easily taken apart for adjustment and repair, this application being a continuation of the application filed by me March 29, 1882, bearing Serial No. 56,720.

In the accompanying drawings,which illustrate my invention, Figure l is a vertical elevation or front View of a pump embodying my improvements, the parts being partly in section; and Fig. 2 is a side View partly in section.

A in the accompanying drawings refers to the-main pipe, which is closed at its upper end by a suitable cap or covering-plate, a, which is preferably a casting, so as to make said pipe A not only serve the purpose of an air-chamber, for which it is primarily intended, but also serve as a support for the pumphandle A. The cap a is provided with a vertical opening, a,which is bisected by openings a", through which passes a pivot-pi n for attaching the handle or lever to the cap, which cap is internally screw-threaded, while the pipe A at its upper end is externally threaded, so as to engage therewith.

The pipe A passes through the platform H, from which the pump is suspended, and this pipe is suitably secured to the platform by bolts or setscrews,so that thc pipe can be vertically adjusted with respect to the platform.

B refers to the spout branch, the upper end of which is curved downwardly in the usual manner, so that the discharge end of this spout branch will project away from the pipe A and be at right angles with the pump-handle A. The lower end of this spout brauch is externally screw-threaded for engagement with a threaded opening in a casting, C, to which casting the lower end of pipe A is also attached. The spout branch, besides being connected to the casting C, is also braced by the platform H, and this spout branch or discharge-pipe is of such a length that its highest portion will be below the upper portion of the pipe A or air-chamber.

The-casting C, hereinbefore referred to, is practically a three-way joint,and is made of a single piece, which is hollow and has internally-screw-threaded openings for the reception of the lower ends of the pipe or barrel A, discharge-pipe B, and the upper end of the pipe D, the offset C being to one side of the openings c and c', which are on a vertical line with each other.

E refers tothe pumpcylinders, which comprise a lifting and a forcing cylinder, which are cast in a single piece and are provided with an offset, E', which is open at its upper end, said opening being internally screw-threaded for the reception of the pipe D. The opening e between this offset and cylinder E is at a point above the upward limit of the stroke of the valved piston which operates inthe cylinder l and below the limit of the movement of the piston of the smaller cylinder, c, located immediately above the main cylinder y. The smaller cylinder, z, is formed integral with the main cylinder y, and the offset E is on a vertical line with the main pipe A.

The casting E, comprising the cylinders y and z and offset E', is made of a single piece,

each part being integral with the other, and roo this casting is provided at a point opposite the offset E with a projection, e, which is per` Y forated for the reception of a brace-rod, G, the

ends of which are screw-threaded for the reception of nuts for seci'lring the same to the casting E and to the platform H. By locating the brace-rod G opposite the offset E', and consequently to one side of the pipes A and D, lateral strain will be prevented and the casting will hang or be suspended in a vertical position from pipe A and rod G, and movement of said casting will be prevented when the piston-rod is operated.

By making the cylinders y and offset E of a single piece 'I am not only able to make them cheaply, but also obviate all liability of leakage and the necessity of adjusting the parts in setting up the pump, in addition to having all the parts rigid to each other.

At the bottom of thelifting-cylinder g/,which is provided with a flange, d, is attached a tube or pipe, I, the lower end of which extends below the water-level, and adjacent to the upper end of this pipe I is located a valve. rIhis u suction-pipe I, the means for connecting the same to the cylinder, and the valve i are of ordinary construction and form, per se, no part of my invention, though they are essential to the operation of the pump hereinbefore described.

The piston-rod F at its upper end is pivotally attached to the short arm of the pumphandle and passes through an opening in the platform II, and to the lower portion of said rod is attached pistons f and f', the lower piston, j", being valvcd, while the upper one, j", lits snugly in the cylinder By the construction hereinbefore described it will be seen that I provide a pump having a forcing-cylinder, c, to which is connected directly a pipe for carrying the water therefrom, above which pipe is formed a compression or air chamber and a discharge-pipe or spout branch which is attached so as to communicate directly with boththe pipe for carrying the water from the piston and the compression-chamber, said compression-chamber and discharge-spout extending above the platform, so that the compression-chamber may form a support for the operating handle or lever.

A pump constructed as hereinbefore described is intended and adapted for use in deep wells, and the pipe D,which connects the airchamber with the cylinders, is of alength equal to the depth of the well,less about twenty feet, the cylinders being usually located not more than thirty feet above the water-level, so that the water can be raised. to the cylinders by suction. By employing'y this connecting-pipe D it will be seen that the pump can be advantageously used in wells which are over thirty feet in depth, and when this pipe is not em- Uployed the pump will not operate satisfactorily in wells over thirty-four feet deep, as the water cannot be raised above that height advantageously by suction and atmospheric pressure, and as the cylinders are suspended in the well at a great distance from the p1atform it is obvious that without the brace-rod, hereinbefore described, the cylinders would swing out'of line with the piston-rod. especially as the construction of the cylinders is such, that they would swing to one side. This brace-rod supports the cylinders and prevents them swinging off the center and is essential to the practical operation of a pump constructed in accordance with myinvention. The ends of the brace-rods being screw-threaded and provided with nuts, this brace-rod can be adjusted to bring the pump-cylinders on a line with the piston-rod.

rIhe operation of my invention is as follows: W'hen the piston-rod F is recprocated by the handle A. in the usual manner, the water will be drawn from the well through the pipe I, so as to ifill the cylinder y, which, by reason of the valvcd piston f, is both a suction and lifting cylinder, and the water will be raised above the valve j", so as to fill the smaller cylinder, z, and the space in the offset E. Vhen the piston-rod is further reciproeated on the upstroke of the piston-recht?, the water will be lifted and forced through tle main dischargepipe D and enter the casting C, a portion thereof passing from the casting into the pipe A, the upper portion of the same forming an air-chamber, and after the air has been compressed therein suiiiciently the water will be discharged through the spout branch by reason of the force applied on the downstroke of the piston-rod,which carries the piston F, thus providing a means whereby a continuous flow will be kept up as the piston-rod is moved either up or down, though the water in the cylinder is only raised on the upstroke, as the compressed air in the elongated air chamber or pipe A reacts upon the water contained therein and forces it out of the dischargespout. It will also ber-observed that on the downstroke of the piston-rodthe water contained in the small cylinder is forced into the discharge-spout, and that the air-chamber and small cylinder act in conjunction with each other on the downstroke, so as to give a flow out of the discharge-pipe which is equal ICO IOS

or even greater than the iiow caused by the upstrolie of the piston-rod.

I am aware that prior to my invention it has been proposed to provide a pump with cylinders the upper-one of which is of less diameter than the lower one, and provide said cylinders with a piston-rod which carries a piston with a valve which moves in the lower cylinder and a tight piston for the upper cylinder, the discharge-pipe being located between the limit of the movement of the upper and lower pistons, as shown in the patent' of G. C. Selfridge, dated September 4,1860. p

What I claim as new, and desire to secure by Letters Patent, isM

l. The combination, in a force-pump, of a pipe, A, secured to a platform so as to be vertically adjustable thereon, said pipe being provided at its top with a slotted cap for pivoting the pumphandle thereto, a discharge pipe extending through the platform and communicating with the pipe A by a three-way tasting, a pipe, D, also attached to said easting, a suction and lift cylinder, y, and forcingeylinder e, a piston-rod carrying a piston and valved. piston, an operating-handle, andan adf justable brace-rod extending from the platform to the opposite side of the cylinder from the pipe D, substantially as Ishown, and for the purpose set forth.

2. Theeombination, in apnnip, of thethreeway joint C, made of a single piece and provided with internal screw-threads, a supplypipe, D, for conveying water to thelower opening in said three-way joiii't, a discharge-pipe, l

B, and a tubular support, A, forming an airehamber, an operating-handle pivot-ed to the upper end of the ainehamber, the pipes A, B, and D being externally screw-threaded for engaging with the openings in the three-way joint, cylinders y and 2, having an. offset between them to which the pipe D is attached, and means for securing the pipe A adjustably to the platform, the parts being organized substantially as shown, and for the purpose set forth.

In testimony whereof I ali'ix my signature in presence of two witnesses.
