IMPROVEMENT IN WATER-METERS.

Specification forming part of Letters Patent No. 47,866, dated May 23, 1865.

will enable those skilled in the art to make and use the same, reference being bad to the accompanying drawings,forniing part of this specification, in which-- Figure 1 is a sectional elevation of a watermeter constructed after my inv ention,taken on theline m of Fig. 3, the side being broken away ih part to show the location of the gearing or wheel-work by which motion is transmitted to the indices of the meter. Fig. 2 isa plan view of my meter. Fig. 3 isa plan view of a horizontal section of the meter below the plate 1/), showing the water-chamber C. Fig. 4 is a detailed View of the gate h.

Similar letters of reference indicate corresponding parts.

This invention consists in adapting the principles of construction of the ordinary central discharge water-wheel .to the purposes of a water-meter.-

A represents the water-meter, composed of the chamber B, which contains the wheelwork and indices and dials for recording the work done or the water passed through the meter, and of the water-chamber O, the two chambers being separated by a metallic diaphragm, p, perforated at its center to permit the passage of the shaft I) from the waterchamber to the index-chamber. The two chambers are secured together by means of their flanges c and], which are bolted together .by screw-bolts g, the diaphragm 1) being socured between them. The shaft 1) is properly stepped and secured according to the art of the machinist, its lower end being supported upon the cross-piece k at the mouth of the central discharge-pipe, b.

- The inductionpipe of the meter is designated by the letter d, and it hasa screw-thread out upon its exterior to enable me to connect the inlet-passage 0 tothe point in its side.

A gate h, is set vertically in the inlet passage 0 along its inner side, being secured therein by means of a fulcrum-pin, i, which passes through the flanges e and f, the diaphragm p,

and a flange, j, which projects from the. head of the gate at right angles thereto. The gatcj his to be set by means of its fulcrum i at any desired angle in the inlet-passage 0, the measure of the capacity of the meter being altered by the contraction and enlargement of the inlet by this means. The passage of the water through the water-chamber will turn the vanes a and their shaft D, and thereby V the wheel-work in the index-chamber will be operated so as to cause the amount of work or the number of revolutions of the shaft to be recorded in the ordinary manner, the water being discharged through the central opening, 11

' The graduation of the wheel-work with the capacity of the inlet-passage O and of the water-chain her and the graduation of the inlet-passage itself by means of the gate are to be made in the usual way, and I have not thought it necessary to ascertain them for the purposes of this application, as these results are not embraced in the scope of my invention.

I claim as new and desire to secure by Letters Patent- The combination of thewings a a, shaft D, rate h, and inlet-passage 0, all arranged to iperate substantially as specified.
