Application filed July 9,1888. Serial No. 279,374. (No model,)

To all whom it may concern:

Be it known that I, George A. Graeser, a citizen of the United States, residing at Chicago, in the county of Cook and State of Uli5 nois, have invented certain new and useful Improvements in Water-Meters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, io in which—

Figure 1 is a side view of my improved meter as the same appears when connected with the usual service-pipes. Fig. 2 is an enlarged longitudinal sectional view. Fig. 3 is a bot15 tom view taken upon the line £Z/ tUj Fig. 2, viewed in the direction of the arrow there shown. Fig. 4 is a vertical sectional view of the water-wheel and its surrounding parts and bearings; and Fig. 5 is an enlarged verti20 cal sectional view of a portion of the inletpipe, showing my improved device for regulating the flow of water.

Like letters of reference indicate like parts in the different figures.

The primary object of my invention is to provide a water-meter in which the flow through the induction-pipe to the water-wheel may be increased or diminished; or, if desired, anon-metered passage maybe provided, 30 whereby the meter may be gaged to deliver the exact quantity of liquid designated by the indicator.

A further object is to so construct a waterwheel in combination with deflectors that the 35 flow of the water may act with constant unvarying and certain effect thereon, while the friction may be reduced to a minimum, all of which is hereinafter more particularly described, and definitely pointed out in the 40 claim.

Referring to the drawings, A represents the case which contains the meter mechanism, and which is divided into three compartments by means of the intervening removable plates, a 45 a', forming chambers BCD. A portion of the case A' is separated from the main case, and is provided with a flange, a², which is arranged to fit over the body of said main'case, to which it may be attached by means of screws or 50 otherwise. Said part A' is provided with a hinged cap, a³, to permit the dial a⁴ to be inspected.

Cast or formed, by preference upon the case A, are pipes E and F, the former of. which is the induction-pipe and communicates directly 55 with the meter-chamber, while the latter leads from the chamber C. Ports c c, Figs. 2 and 3, serve as a communication between the chambers B C, through which the water may flow to the eduction-pipe. 60

G is a duct which leads to the chamber C and communicates with the pipe E through a passage, g, which is adapted to be closed or opened by means of a screw-plug, G', tapped within a nipple, G³. Said screw is provided 65 with a non-threaded extension, g', the diameter of which is smaller than that of the opening through which it passes. The object of said extension g' will be hereinafter more fully stated. To prevent leakage, I provide 70 a screw-cap, g², which may be removed when it is found necessary to adjust the screw G'.

Within the meter - chamber Β, I place a wheel, H, preferably made from sheet metal, and provided with flat radial spokes h. Said 75 wheel is mounted upon a shaft, Id, which is placed upon a pivotal bearing adj ustable by means of a set-screw, Id, tapped into the bot. tom plate, B', Figs. 2 and 4.; The wheel H is . provided with a series of depending paddles, 80 7i³, which rotate around an annular flange, &, formed upon the plate V, said flange serving as a guide whereby a channel may be formed in the line of the path of the paddles. It will be observed by reference to Fig. 3 that the 85 line of the inlet and outlet pipes, respectively, is tangential to the circle described by the movement of the paddles. To serve as a deflector and secure the action of the water upon the paddles, I provide a plate, H', which is 90 arranged parallel to the plane of the axes of the pipes E F, as shown in. Fig. 3, and is rigidly attached to the plate a. Within the chambers C D is arranged the usual clock mechanism, as represented, and which needs no de- 95 scription, to actuate the indicators upon the dial, and which is primarily driven by the wheel H.

The operation of said meter is as follows:

Assuming the duct G to be closed by the plug ico

G', thereby causing all of the water to be directed through the metered chamber B, and that the indicator registers a flow of one hundred gallons during a given time, but that 5 only ninety-five gallons by actual measurement is enabled to pass during that time, the discrepancy may be corrected by so regulating the screw G' as to open a passage to the duct G sufficient to permit five gallons to flow i o through the unmetered chamber C; but it may be found, even when the duct G is closed, that more water passes through the metered passage than is actually registered. In this event the plug G' should be so screwed down that 15 the projection g' may enter the pipe E, as indicated in dotted lines in Fig. 2, and form an obstruction therein sufficient to diminish tiie flow of water, so that its volume may be correctly indicated.
