SPECIFICATION forming part of Letters Patent No. 392,730, dated November 13, 1888.

Application filed Septemberlfi, 1887. Serial No. 249,780. (No model.)

To aZZ whom it may concern.-

Be it known that LVV RIGHT HOWARD, a citizen of the United States, residing at Fitchburg, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in lVater-Motors; 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, which form part of this specification.

My invention relates to certain improvements upon that class of water-motors that are r 5 adapted, according to size, to be operated by the pressure of water through a pipe from the street-main or from a reservoir when it is desired to drive machines-as scroll-saws, sewing-maehines, and the like-or to be made proportionately large in size for driving heavy machinery in mills or for manufacturing pur poses, and to receive the water in greater quantities through. conduits or large troughs,whieh convey it to the pipe that deposits it in the buckets on the wheel of the motor.

The principal object of my invention is to provide a case with an upper and lower half having strengthening-ribs thereon with their adjoining edges planed and fitted together to form an air and water tight joint, each half of the case being provided with a bearingsurface for the journal of the wheel, so as to keep it always on the same line, and also to provide a feed for letting the water on the wheel at any desired angle to regulate and govern the power, or for allowing it to pass through the case without coming in contact with the wheel; and it consists in the construction hereinafter described, and more particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a side view of my improved motor. Fig. 2 is a longitudinal sectional view. Fig. 3 is a vertical cross-sectional view. Fig. 4 is a detail view showing the plug valve or cook. Fig. 5 is a sectional view of a modified form of valve; and Fig. 6 is a longitudinal section of the same, showing a part of the case.

Like letters of reference refer to correspond- 50 ing parts in each figure of the drawings.

A represents the wheel-case, which is made of cast metal,and is composed of an nppersed tion, B, and a lower section, 13, each of which envelops 0ne-half of the wheel and has vertical strengthening bars or ribs a on their sides 5 5 integral with the case. The adjoining edges of the sections serve as seats, which are thickened and provided with a projecting flange, b, which serves as lateral strengthening bars or ribs, to the thin shell of metal of which the sections are usually made. These edges and flanges forming the seats are planed or trued down to form an air and water tight joint when placed together withoutthe use of rubber or other usual packing. The flanges at the ends 6 of the case are widened into ears 0, to receive. bolts for securing the two sections together around the wheel. When the two sections of the case are thus planed and securely fastened together, the re-enforeed part or hub D will be one half upon the upper and the other half upon the lower part of the ease. The hub is then bored and the shaft-boxes fitted in, and, being just equally divided between the upper and lower sections, they are at all times upon a line, and there is a less liability of their getting out of true.

The top section, B, of the case is provided with a vent or air hole, 0, in its periphery for the escape of air, that would otherwise become compressed about the wheel E in the chamber of the case and somewhat impede its motion.

The wheel Eis provided with a partition, 01, on its periphery, on each side of which is placed a row of buckets, the row on one side alternating or coming between the buckets of the 0pposite side, so that when the bucket on one side is receiving the stream in its center the opposite bucket will receive the stream upon its edge, thus giving the wheel a steady, unbroken motion.

In the lower section of the case beneath the wheel there is a large air-chamber, F, to receive the water as it comes from the wheel after use, or through which the water may be 5 passed into the pipe 6 without coming in contact with the wheel. This chamber is sufficiently large to enable a free circulation and to produce a current of air through the vent c in the upper section sufficient to prevent IOO stoppage of water in the chamber. In the upper portion of the chamber F and on the opposite side from the cook or valve there is a fender, f, cast integral with the case, which extends across on the inside thereof and to the periphery of the wheel, for the purpose of catching the waste water as it is thrown out of the buckets and directing it into the chamber below to prevent its being carried around with and retarding the motion of the wheel.

A supply or water pipe, G, is east integral with the lower section, B, of the case; or the pipe may be placed in the mold and the lower section of the case cast around it to form one solid structure. This pipe is arranged in the opposite side of the case from the fender f and stands at an angle of about forty-five degrees to the plane of the case, so that the wa ter flowing through it and passing into the chamber F on a direct line with its channel will not come in contact with the wheel. The inner end of the here or channel of the pipe is contracted to form holes 9 just sufficient in size to admit a supply of water that is capable of passing through the valve,while the water in the larger portion of the bore presses upon and forces the water through the holes.

A plug valve or cook, I-I, extends through the lower section, B, of the case and inner end of the pipe at right angles therewith, which forms its seat, and is secured in place by a nut or other suitable means, and has a ,hand-wheel, Z, or other means on the outside of the case for turning it. The valve is provided with lateral holes h,which register with the contracted holes of the pipe and are adapted to guide separate streams directly into the different rows of buckets on the wheel adjacent to the valve.

The inner end of the pipe G, forming the valve'seat, is notched or cut out at I, forming projections 2' beyond the pipe proper, so that one half of the valve-seat is formed in the end of the pipe and the other half in the projections. By this construction of valve-seat the valve is adapted to be turned so as to direct the streams upon the wheel at any desired angle.

When the greatest possible speed of the wheel is required, the streams are directed downward into the bottom of the buckets, and when a less degree of speed is desired the streams may be turned so as to strike the wheel on a plane with the valve, allowing the water to merely fall into the buckets and the wheel to be turned by the weight of the water.

It is frequently desirable to stop the motorwheel in a much shorter time than can be done by merely turning off the water. To accomplish this the valve is turned so as to direct the stream upward against the inclined outer portions of the buckets, so that its force upon the wheel will be exerted in the opposite direction from that when it is thrown into the buckets, thereby impeding its motion and stopping its movement.

\Vhen it is desired to clean the pipes supplying the wheel. without operating the ma chine, to relieve them of dirt and other aceumulations that have settled therein, or to run the water beyond the machine to be used for other purposes, the valve or cock H is turned so as to direct the streams into the chamber 1 below and out through the pipe 6 without their coming in contact with the buckets of the wheel. K

in the modification of my valve I have shown a slightly-diiierent construction of the device, whereby there is a fixed receivingplug, J, rigidly secured to one side of the case on the inner side by a screw or other means. lhis plug has holes j, that register with the holes g in the contracted end of the pipe G, and which also communicate with radiating holes K on the opposite side of the plug,.

which are at different angles from the hole j, for the purpose of throwing the stream on the wheel at different points or for directing it into the chamber below without its comingin contact with the wheel. 7

In the opposite side of the case B from where the plug J is secured there is arevolving valve-sleeve, L, that extends across the case on the inner side and envelops the plug J, making a close joint with the seat or end of the pipe G. This sleeve has projecting outside the case a hand-wheel, l, or other means for'turning it, and is provided with holes m, that are adapted to be turned to register with the holes 7 in the pipe and the holesj in the plug. On the opposite side of the sleeve there are holes a, that at the same time register with any desired set of radiating holes R in the plug, thus enabling the stream to be directed through either set of the holes K that the occasion may require at any one time, while the other radiating holes of the plug are closed by the sleeve.

WVhen it is desired to shut the water off from the plug altogether, the sleeve is turned just enough to bring its solid septum 0 between the holes or over the holes 9 of the pipe, as

may be shown by any desired suitable form of indicator on the outside of the ease.

I-Iaving fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-- 1. The combination, with a water-motor case having a supply-pipe in one side thereof cast integral with the case and at an obtuse angle to the plane of the base, the inner end of the pipe proper forming part of a valveseat, of a valve at right angles to the pipe and against said seat, adapted to be turned to guide a stream downward into the waste-pipe clear of the wheel or into the buckets of the wheehand to be reversed, throwing the stream upward against the outerinelined sides of the buckets,in1peding the motion of the wheel, as set forth.

2. The combination, with a supply-pipe for a water-motor, having a notched inner end with projections on its sides beyond its end, the end of the pipe forming part of a valve ICO seat, of a valve in said seat at right angles to the pipe, consisting of a fixed receiving-plug provided with holes registering with the holes in the pipe, said holes in the plug being extended to form diverging holes in the opposite side thereof, said plug being enveloped in a perforated sleeve revolving upon the plug, the holes of the sleeve registering with the holes of the plug and pipe, as and for the purpose set forth.

3. The combination,with a water-motor ease east in upper and lower shell-sections, the adjoining edges of the sections having outwardlyflanged projections, forming a tightjoint, the lower section having a supply-pipe on one side and a shield on the other side integral with the section, the inner end of the pipe being notched and having projections on its sides extending beyond its end, the projections and end of the pipe forming a valve-seat, of a Valve in said seat resting against the innor end of the pipe and at right angles therewith, consisting of a fixed receiving-plug having holes therein registering with. the pipe and extended to form diverging holes in the opposite side thereof, said plug being enveloped in a perforated sleeve revolving around the plug and over the end of the pipe, the holes of the sleeve registering with those of the pipe and plug, as set forth.

In testimony whereofI affix my signature in presence of two witnesses.
