WATER-METER.

Specification of Letters Patent! -P3tgntgd J an, 1'7, 1911,

Application filed January 10, 1910. Serial No. 537,344.

To all whom it may concern:

Be it known that I, JUSTUS ROYAL KIN- NEY, a citizen of the United States of America, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in \Vater-lVIeters, of which the following is a specification;

.This invention relates to water meters and has for its object the production of a device of this class which will be effective and noiseless in its operation.

The'invention consists in certain novel features and arrangement of parts which will be readily understood by reference to the drawings and to the claims hereinafter given.

Of the drawings: Figure 1 represents an elevation of the meter embodying the features of the present invention a portion of the register casing being broken in sect-ion. Fig. 2 represents a horizontal section of the same,.the cutting plane being on line 2-2 of Fig. 1. Fig. 3 represents a vertical section of the same, the cutting plane being on line 33 of Fig. 2. Fig. 1 represents a similar section showing the piston and its pivoted bearing member in another position.

In the. drawings, :10 represents a cylindrical casing having a division wall 11 intermediate its ends, preferably made 'integral therewith. To each end 'of this casing 10 is secured an end plate'12 by suitable bolts-13f Each of the end plates 12 is provided with a bushing member 14 adapted to receive the reduced ends of a revoluble shaft 15 and form a bearing therefor.

In the casing 10 betweenthe division wall 11 and the two end plates 12 are formed two al-ined cylindrical chambers each communicating with an inlet chamber 16, and each communicatingwvith an outlet. chamber 17.

The two inlet chambers 16 are connected by means of an opening 18 through the division wall 11, while the two outlet chambers 17 are similarly connected by means of an open ing 19 in said division wall 11. An inlet pipe, 20 admit-s fluid to the inlet chambers 16 while the' fluid contained within the outlet chambers 17 passes therefrom through the outlet pipe 21. In each cylindrical.

chamber, mounted upon and keyed to the shaft 15 is a cylindrical piston 22. The shaft 15 is centrally disposed within the,

piston chambers and the pistons 22 are eccentrically mounted thereon with. the highest points thereof diametrically opposite one another. In the rotation of the shaft 15 the highest point of the pistons 22 is adapted to contact with the cylindrical wall of the piston chamberand prevents leakage thereby.'

Intermediate the inlet and outletchambers 16 and 17 is a seat 23 for the pivotal end 24 of a blade or plate 25, the outer face of which is in the path of the fluid admitted to the interior of said casing 10 through the inletpipe 20. The pressure of the fluidad mitted'through the pipe 20 retains the blade 25 in contact with the periphery of the piston 22, it being obvious that a greater pressure is always maintained on the inlet side of the blade 25 than upon the opposite side owing to the power consumed in forcing the piston 22 about theaxis of the shaft 15 thus reducing the pressure of the fluid passing through the outlet chamber 17 and pipe 21. The blade 25 is always thusretained in contact with the periphery of the piston 22 by theexcess pressure on the outer face of the blade, over that upon its inner face. In this manner any leakage of. the fluid between the two is prevented.

In the position shown in full lines.and dotted lines in Fig. 3 of the drawings, the fluid entering the inlet chambers 16 is prevented from entering the nearest piston chamber by the blade 25 which acts as' avalve to prevent such admission. The fluid passing through the pipe 20 will pass through the opening 18in the division wall 11 into the farther piston chamber in which the piston 22 and blade 25 are in the positions shown in dotted lines in said figure; It is obvious therefore that the fluid entering the piston chainber will act upon the piston to move it about the axis of the shaft 15 inthe direction of the arrow on said figure.- The fluid passing through this pipe 20 will continue to be admitted to the farther piston chamber until the outlet port has been uncovered by. the highest point of the piston, and acting upon the blade 25, is moved into the'position shown in full lines in Fig. 3 of the drawings to prevent any further admission to said piston chamber.

When this point has been reached, the en-.

tering fluid will enter the other' piston chamher and by rotating the shaft 15' will force 1 r the fluid in advance ofthe' first mentioned piston 22 into the outlet chamber.

It is obvious from an inspection of the dotted lines in Fig. 3,-while at other times its inner face is in contact with said peripliery. In order, ho wever, to still further vary the movement of said blade and to secure a quick cut-off, a projection 26 is provided on its inner face, which during certain portions of the revolution of the piston 22 will be acted upon thereby to accord a quicker movement to the blade 25 than would be the case if the contact was madeat a greater distance from the pivot.

It is obvious that at each revolution of the piston, a certain amount of fluid is admitted to the piston chamber and passes through the same into the outlet chamber 17 and therefrom through the outlet pipe 21. This can be accurately measured and the amount of liquid passing through the meter registered by providing the shaft 15 with an extension or stem 27 extending through one of the end plates l2and securing to the outer end of said stem a gear 28 which is adapted to operate another gear 29 forming a part of a register 30 which maybe of any well known description. This register is mounted in a casing 31 secured to one of-thc end plates 12. The stem 27 passes through a stuflin'g box 32 by which any leakage is prevented from the piston chambers. By such a construction as is shown in the drawings and herein described, the fluid *passing through the casing may be accurately measured and registered,while owing to the piston being cylindrical and the piston chamber also being cylindrical, with only that portion of the piston farthest removed from its axis con,-

tacting with the cylindrical wall. of its chamber,-the device will'be perfectly noiseless.-

A The rojectioii' 26 is so shaped that it will retain the blade 25' in position to shut off all communication between the inlet chamber 1 6 and the piston chamber, while the contacting portion'of the piston -22 is passing from the point 33 to the-point 34, -thereby preventing any. fluid passing around the piston 22in the direction of arrow a and out through theoutlet pipe 21,

termediate while. the, highest point .of the 'pistonis' inese two points 33.-34. It-is obvious that if this should be permitted a certain portion of the fluid would pass from.

theinlet 20 to the outlet 21 that could not be measured. The blade 25 does not open,

therefore to adniit fluid behind the piston 2 2"ui1til. the highest point of said piston reaches; the point 35 when. "the. inlet fluid '65 ;,passes' in; the piston chamber, and this,fluid thus admitted is prevented from passing therefrom until the highest point of said 'piston 22 reaches the point 33 when it will be permitted to pass into the outlet pipe 21. By this means aknown quantity of fluid passes through the piston chamber at each revolution of the piston, the amount of which may be readily determined and there- ,fo'rej'nccurately registered by the devices provided for this purpose. This forms a vention.'

The operation of the invention and the many advantages thereof, it is believed, will be fully understood without further de* scription.
