To all whom it may concern:

Be it known that I, JAMES WATERS, a citizen of the United States, residing at Minne- 1 apolis, in the county of Hennepin and State of 1 Minnesota, have invented certain new anduse- 1 ful Improvements in Pumping-Engines; and-I 1 do hereby declare the following to be afull, 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.

This invention relates to a pumping-engine composed of three or more barrels arranged radially around an upright shaft, to a crank of which all the plungers are connected. Heretofore it has been customary to drive such upright shaft by means of a turbine water-wheel or other motor through the intervention of gearing. Such a combination is obnoxious to many objections, principal among which are the following, namely: The plant requires a comparatively large space-a serious item of expense where property is valuable-and the connecting machinery is cumbersome, noisy, liable to derangement, and expensive.

One object of my invention is to overcome these and other objections.

To this end my improvement consists in mounting the pumps directly over a turbine water-wheel, so that the crank-shaft of the pumps may either constitute the top end of the water-wheel shaft or be coupleddirectly therei to.

My improvement further. consists in connecting the several pumps bytwo continuous preferably circular pipes, one of which serves as a common suction-pipe, the other as a common discharge-pipe, and both together as a framework for connecting the pumps and giving support to the crank-shaft.

In order that my invention anay be clearly understood, I have illustrated it in the annexed drawings, and will proceedto describe thebest formthereof at present known to me.

Figure 1 is aplan view of apumping-engine constructed in accordance with my invention and driven by a turbine water-wheel, some parts being shownin section. Fig. 2 is avertical section thereof'on line as a: of Fig. 1, a steam-cylinder being shown attachedto one of the pump-barrels to indicate the mode of operating the pumps by steam-engines.

The same letters of referenceindicate iden tical parts in all the figures.

The pumps may be'of the form shown or of any other preferred construction. In the example illustrated the barrels A A A are open at the inner end, and are provided with hollow plunger-s B 1313, pivoted to the connected with lateral branches 0. An airchamber, F,

is mounted upon the upper side of each pumpbarrel, and any ordinary discharge-valve (not shown) will be used to control the opening or openings of communication between the pumpbarrel and the air-chamber. Each air chamher is constructed with a lateral branch, f.

'The branches 0 are all connected to corre sponding lateral branches on the common suc- .tion-pipe G, which is preferably of circular formy'as shown, though that particular form is not essential. This suction-pipe is provided with an extra branch, G, for the attachment of the pipe through which the water is drawn up. The branches f of the air-chambers are similarly connected to corresponding branches of the common discharge-pipe, H, also preferably of circular form, and provided with' an extra branch, H, for the attachment of the distributing-main. The pipes G and H, being located, respectively, above and below the crank d, are constructed with spider-arms G and H terminating in central hubs, G and H bored and boxed to formbearings for the crankshaft on each side and close to the crank there- U T PATENT OFFICE The pumps may have a construction differ ent from that shown and describ ed; but in every case the crank-shaft D thereof is to be an upright one, in order that by mounting the pumps directly above a turbine water-wheel, I, said crank-shaft may be in line with shaft K of said water-wheel, and either constitute the upper end thereof, as shown, or be suitably coupled thereto.

My improvement relating to the structure of the pumping-engine may be used without the other improvement described. The pumps may, for instance, be driven by steam. In that case I prefer to attach a steam-engine to each pump, substantially as shown on one of the pumps in Fig. 2, the piston-rod of the steamengine being directly secured to the pumpplunger, all the plungers remaining connected to a common central crank-shaft.

My improved pumping-engine is more es pecially designed for water-works for supplying cities and towns with water, but may be advantageously used in private establishments I and. for general purposes.

Having thus described my invention, what I claim is I. The combination, substantially as before set forth, of a series of pumps, the barrels of which are arranged radially around a common center, a vertical CI'filk-Shdfl] for driving the plungers of the several pumps, and a turbine water-wheel on the upper end of the shaft of which said crank-shaft is an extension.

2. The combination, substantially as before set forth, of a series of pumps, the barrels of which are arranged radially around a common center, the central crank-shaft to which all the plungers are connected, the continuous common suction-pipe, and the continuous common discharge-pipe, said pipes being constructed with spider-webs and central bearings, so as to serve as .a' frame-work for connecting the pumps and supporting the crank-shaft.

In testimony whereof I 21-ffiX'1lI5 signature in presence of two witnesses.
