IMPROVEMENT IN WATER-METERS..

Speciiication forming part of Letters Patent No. 113;@3069 dated December 24, 1872.

To all whom it may concern:

Be it known that I, Wnnsrnn PARK, of Norwich, in the county of New London and State of Connecticut, have invented certain Improvements in Tater-Meters, of which the following is a specification:

The iirst part of my invention relates to the construction of a Water-passage through the meter, opening and closing in such a manner that, when open, it shall be capable of deliveringqfreely the whole capacity of the supply; and Whenl the supply is diminished the water-Way is contracted until-when the smallest stream is running-its whole impulse is concentrated, through a very small opening, upon a small motor, only large enough to run the registerin g mechanism 5 the obj ect being to make the motor sensitive to the smallest iow, and to reduce the size, expense, and friction as much as possible without impairing its capacity to discharge freely larger or full sized streams. The second part of my invention relates to the combination of such mechanism and wheel-gearing as will move the indicators according to the size of the stream iiowing through the water-Way and giving motion to the motor, so as to make the first part of my invention practicable for the. accurate measurement of all sized streams, as the motion ofthe motor represents the velocity of the stream, which, by the mechanism, is multiplied by its size 5 hence indicating the quantity of water.

Figure l is a top viewA of a machine embodying my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a side elevation of the tlume and valve and those parts not shown in Fig. 2. Fig. 4 is a vertical transverse section of the flume taken in any part of its length.

The drawing shows the full size of the parts of a meter for ordinary domestic use.

A is a chamber, into which the water flows from the supply-pipe W, and from which it ilows evenly into the flume B, and is discharged at the opposite end of the case, as indicated by the arrow, the case itself not being shown in the drawing. U is a rectangular bar or valve pivoted at S, which falls by its own weight, and is raised by therunning stream, the end of the ume conforming to the arc in which the end of the bar C moves. D is the Water-wheel or motor, which is preferably formed like an inverted tub, as shown in the drawing, having small iioats attached to its periphery. This gives motion to the wheel E by means of the worm L. J is the rack, secured to the bar C by the connection 0, and which, by means of the sector H, opens back the guard G as the valve is raised. F is a ratchetwheel, from which, by the pinion It, motion may be given to the ordinary indicators used in meters. V is the shaft xed upon the side of the flume, upon which both the Wheels F E and the guard Gr all revolve. N N is a pawl, pivoted through the wheel E, and revolving with it. One end, resting upon the guard G, through the upper part of its revolution, raises the other end clear of the teeth of the ratchet, except through the space that the guard G is thrown back bythe raising of the valve, when the pawl dropsby its own weight into the teeth, and moves the ratchetwheel more or less, according to the height of the valve. T is a stationary guard to throw the pawl out of theL ratchet-teeth, when its own \weight keeps it out through the lower part of its revolution 5 and the pawl should be provided with a stoppin to prevent its falling only just out of the teeth. M is the step, and Kis the upper bearing of the water-wheel, and P l? are thc supports on which the Hume rests. U U are. one or both,bar-magnets, one attached to and revolved by the mechanism inside; and the other following upon the outside of the case, and moving the indicators, the case being made thin between them, as indicated by the line in Fig. l, so as to make the attraction as great as practicable, and each bar revolving upon a Vpoint to diminish friction.

I claim as my inventionl. The automatic valve C, adjusted in the iiume B, when so connected with the registering mechanism in a water-meter as to vary the movement of the indicators according to the opening of the valve, for the purpose herein set forth.

2. Ilhe water-wheel D, so constructed and arranged that only the lower stratum of water shall impinge upon it, when used to move a pawl Whose action is varied in proportion to the opening of an automatic valve through G, and ratchet-Wheel F, adapted to move the Whichthe Wnterisconcentratedupouthe Wheel, indicator-wheels in proportion to the volume as herein described. ot' water owing through a. water-meter.

3. The rack ,J and sector H, moving the WEBSTER PARK. gua-rd G inA proportion to the valve-opening, for the purpose of varying the action of the Witnesses: paw-l. ALBERT F. PARK,

4. The combination of the pawl N, guard WILLiAM S. LAIGHTON.
