This invention relates to a combined water motor and pump.

A primary object of the invention is to provide an apparatus for mounting in a stream having a comparatively swift current, which apparatus includes a double acting force pump driven by the motor for delivering water from the stream to any desired point.

Another objectis to so construct such a pump that a maximum quantity of water may be pumped with a minimum expenditure of power,andwhich after the initial cost of installing is paid, operates without any expense whatever, for an indefinite period, and then only slight repairs incident to wear become necessary. n

In carrying out these objects, the invention is susceptible of a wide range of modification without departing from the spirit or sacrificing any of the advantages of the claimed invention, there being shown in the drawings for illustrative purposes a preferred and practical form, in which,

Figure l represents a diagrammatic perspective view showing this improved apparatus mounted in a stream ready for use,

Fig. 8 is a similar view taken on the line 8 8 of Fig. 5.

In the embodiment illustrated, a floating dam l is shown which is designed to be mounted in a stream and anchored to the banks thereof, cables 2 being here shown for this purpose, secured to the front corners of the float and to pulleys 2EL which travel on a cable 2b attached to suitable anchors 3 on the banks of the stream. An endless cable 2G is fastened to the pulleys 2a and is trained around a pulley 2d on the post 3 and conthe rise and fall of the water and yet prevents it from being swept downstream when the current is swift. By using a windlass 70 in connection with the cable 2C the dam may be moved toward or away from the banks of the stream.

This improved floating dam l comprises a central longitudinal extending channel chamber 5 with upstanding longitudinally extending pontoons or air chambers 6 and 7 de# signed to render the apparatus buoyant, and which may be of any desired height and length, according to the size of the stream in which the apparatus is to be located. The front ends of these air chambers 6 and 7 are inclined inwardly, as shown at S and operate to direct the water passing downstream into the channel 5 so that it passes through said channel with considerable force and operates a waterwheel l0 revolubly mounted in the channel at its rear end, as is shown clearly in Figs. 1 and 2. rThe bottom of the channel 5 extends forwardly in advance of the inclined ends of the air chambers and forms a platform 9 as is shown clearly in Fig. 2. This platform `9 is preferably tapered to a point at the front end thereof, asv shown at 9FL and operates to facilitate the ent-rance of the water to the channel 5.

The waterwheel 10 is carried by a shaft 1l which extends transversely across the channel 5 above the topsof the chambers 6 and 7 and is journaled in suitable bearings mounted on said tops. This shaft 1l also extends at one end beyond one side of the float, as is shown clearly in Fig. 2 and has connected A withl its projecting end a crank arm 12 which when the shaft is rotated by the turning of the wheel l0 under the influence of the swift current passing through the channel 5, operates to drive the plunger of a pump 2() which is here shown mounted on the float at one side thereof. To provide for the mounting of this pump 2O suitable transverse bars or beams 13 are secured to the bottom of the float and project at one end beyond one sideV thereof and have mounted thereon the pump 20 which is secured to said beams by U-bolts or hangers 14.

The pump 20 comprises a barrel 21 of any desired size and length according to the quantity of water to be pumped thereby, and on the ends of this barrel 21 are mounted shaped chambers 22 and 32. @ne end of each of these chambers 22 and 32 is secured to the ends of the barrel 21 and the shank portions 23 and 33 thereof have discharge pipes mounted thereon and numbered 40 and 50. These pipes 40 and 50 are detachably con nected with the shanks of the Eshaped chambers by suitable couplings 41 and 51 and Within said couplings are providedi check valves 42 and 52 which are designed to open to let the water out and to close when the water is being@ drawn in to the chamber through the inlets 25 and 35 which are located in the ends of the heads opposite to those connected with the pump barrel. These inlet ends are equipped with inwardly opening inlet valves 24 and 34.

A double acting pump plunger 3S is mounted in the barrel 21 and as shown comprises a cylindrical member 37 provided at its opposite ends with pistons 3S and 39 and through which extends a rod which strengthens the plunger and holds the piston 10 in place. Mounted in the cylinder 3T midway the length thereof is a head 44 which has arms 45 and 46 projecting laterally therefrom and which extend through slots 21a in the pump barrel. A rod 47 extends transversely through the head 44 and the arms 45 and 46 thereof and strengthens said head, said rod also extending through an ey-e formed in the rod 43. This rod 47 projects beyond opposite ends of the arms 45 and 46 and has connected therewith the free ends of a yoke shaped pitman 43, this pitman 48 having its free ends inclined downwardly and inwardly toward the pump barrel and said ends straddle the barrel is shown clearly in Fig. 2. This yoke also straddles the delivery pipe 50 and is connected at its rear end with the crank arm 12 by means of a connecting link 49 fixed to the yoke and pivotally connected with a stud 12a projecting laterally from the free end of the arm 12. It is thus seen that when the shaft 11 is rotated, that the pump plunger 36 will be reciprocated and draw water first into one chamber and then in the other alternately expelling the water from these chambers through the discharge pipes 40 and 50. A horizontally disposed pipe connects the pipe 50 with the pipe 40 and merges into a single pipe 61 through which the water is conducted to any desired place of deposit.

From the above description it will be ob- Vious that this combined pump and water motor, when once installed in a stream, as shown in Fig. 1, will operate indefinitely without any expense or attention.

mames It will also be obvious that the pump 20 may be detached from the crank arm 12 of the water motor and connected with any other suitable driving power.

Without further description it is thought that the features and advantages of the in vention will be readily apparent to those skilled in the art, and it will of course be understood that changes in the form, proportion and minor details of construction may be resorted to, without departing from the spirit of the invention or its scope as claimed.

I claim i In a pump, a cylinder having a detachable inlet and outlet at each end and further provided with a pair of longitudinally entending slots at diametrically opposite points, a double acting piston slidably mounted in the cylinder, laterally extending lugs projecting therefrom at diametrically opposite pointsI and extending through the slots, a rectilinear cross head mounted in said piston, projecting through said piston and providing an aperture, a rod extending transversely through the piston and the aperture of said block and passing through the lugs with the ends thereof extending beyond the lugs, a longitudinally extending rod secured at the ends of said piston, extending through the aperture in said block and having an eye ceiving said transverse rod and a forked lever secured on the ends of the transverse rod against the ends of the lug.

Signed at La Fayette, in the county of Tippecanoe and State of Indiana` this 21st day of February, A. D. 1923. y
