IBCEFICAOI forming part o Letters Patent No. 314,126, dated March 17, 1885.

Application lcd November 2&2, 18H4. (No model.)

nying drawings, which form a part of this Speciiicaton, and in which,-

' Figure 1 is ahorizontal sectional view of my improved water-meter. Fig. 2 is a vertical sectional view of the same taken on the line l 2 in Fig. l. Fig. 3 is a horizontal sectional View of a portion of the meter, illustrating a slight modification in the construction thereof, and Fig. 4 is a vertical sectional view taken on the line 5 6 in Fig. 3.

The same letters refer to the same parts in all the igures. i

This invention relates to water-meters of that class which are provided with a rotary piston; and it has for its object to so construct the same as to compensate for wear upon its component parts during the operation of the meter, thus causing the latter to measure accurately and without loss from leakage.

The invention further has for its object to provide a device which shall possess superior advantages in point of simplicity, durability,l and general eiiiciency.

`With these ends in view the invention consists inv the improved construction and arrangement of parts, which will-be'hereinafter fully described7 and particularly pointed out in the claims.

In the drawings hereto annexed, A designates the outer case, which is bolted to the bottom piece, C, which latter is provided with a cylinder, B, extending upwardly into the outer casing eccentrically with the latter.

Secured centrally to the bottom piece, C, is a vertical spindle, D, upon which revolves an inverted-cup shaped cylinder, B2, the lower edge of which bears upon or against the bottorn piece, C, while the cylindrical collar B of the latter bears at its upper edge against the under side of the top of the cylinder B2. It

will thus be seen that wear upon the edges,

which are designated by b and b2, is mutually `compensated for, so that the parts B, B2, and C shall always be tightly fitted together, and ,the interior space, which is designated by let- `ter E, be absolutely watertight. The cylindrical collar B is provided with entrance and exit ports a and b', connected, respectively, with 4the entrance and exit pipes ai and b3, and opening into the space E, near the narrow or small `side ofthe latter, at which the parts B and B2 are nearly in contact with each other. The v'cylindrical collar B is provided at an intermediate point between the ports with a recess, in which is hinged a vibrating valve, c, the free edge of the-wing of which bears against the inner side of the cylinder B2, with which itis constantly held in contact, partlyby the back-pressure ol" the water in the space E, and

partly by the action of a suitably-arrangedspring, c2. The inner side ot' the cylinder B2 is provided with diametrically-opposite recesses, in which are pivoted vibrating valves e e, extending between the bottom piece, C, and the top of the Vcylinder B2, and the ends of the wings of which bear against the wall of the inner cylindrical collar, B. The said valves are retained automatically in an open position partly by the pressure ofthe water passing through the meter and partly by the action of suitably-arranged springs t' i, arranged in recesses inV the wall of the cylinder B2, and bearing or pressing against the inner sides of the wings ot` the said valves.

lt is obvious that the wings ofthe valves c and e e are to face in opposite directions, in order to enable the latter to pass freely over the former as the cylinder B2 revolves. The

top of the cap or casing A is provided' with a central bearing, 0, provided with a' packing-boX, p, for a small spindle, s, the lower end of which is provided with a rmly-secured arin or lever, y, connecting it with a pin, d, extending upwardly from the revolving cylinder B2. The spindle s, which is thus caused to revolve with the latter, is connected by a suitable gear to a decimal train and index, (not shown in the drawings) which, by registering the number of revolutions ot' the cylinder B2, will denote the exact quantity 'of water passed through, since one revolution of the said cylinder B2 will cause to be dis- IOC) charged the amount of water that can be contained in the space E, the capacity of which must of course be known.

The operation and advantages of this invention will be readily understood from the forcgoing description, taken in connection with the drawings hereto annexed. The wear upon the upper and lower edges of the cylinders B and B2 will be substantially equal, and Willbe compensated for by the weight of the cylinder B2, which practically rests upon the bottom plate, C. In like manner the Wear upon the upper and lower edges of the several valves is compensated for. The inner or free edges of the several valves are constantly held byY their respective springs, as Well as by the water-pressure, against their bearings, and as they become worn will simply open a little farther. The operation ot' the device will thus continue uninterruptedly and accurately until the device is worn out, or until the valves have been worn down so far as to be inoperative. The entrance-pipe a3 of the meter is to be provided with a small opening. n, communicating with the space N between the cylinderB2 and the outer casing, filling the said space with water, the pressure of which will serve to force the cylinder B2 against its bearings. This pressure may be augmented by means of a small opening, m', connecting the exit-port b with the interior of the cylindrical collar B, since the pressure in the eXitport is less than that in the inlet-port by the. amount of pressure required to move or operate the meter. In case of any considerable Wear upon the edges b and b2 of the parts B and B2, this may be compensated for by tightening the nut N', which serves to secure the cylinder B2 upon the spindle D, and in case of wear upon the latter by the revolution of the cylinder`B2 the joint is still kept tight by means ot' a washer, W, arranged under the said nut N', and kept from revolving upon the spindle by any suitable means.

The modification of my invent-ion shown in Figs. 3 and 4 of the drawings consists sin1- ply in substituting for the valve c (shown in Figs. l and 2) a cylindrical rolling valve, y, forced against its bearings by the back-press ure ofthe water,assisted by asuitable spring,x.

rIhe operation is precisely as above described; but this construction may be found to be more durable and satisfactory than the construction illustrated in the preceding tigures.

Other changes in the construction of this device may by extended trial be found useful, and I would therefore have it understood that I do not limit myself to the precise construction herein shown, but reserve to myself yof the said cut-off, substantially as and forthe purpose herein set forth.

2. In a water-meter, the combination, with a casing having an interior eccentric cylindrical collar, and au inverted-cup-shaped cylinder arranged to revolve over and around the same, of the water inlet and outlet, suitable gates or valves, a cut-off, and openings admitting water to the spaces between the outer casing and the revolving cylinder and between the interior of the latter and the space inside the eccentric collar,substantially as and for the purpose herein set forth.

3. In a water-meter, the combination, with a casing having an interior eccentric cylindrical collar, of a central revolving invertedcup-shaped cylinder, and vibrating valves or gates hinged to the inner side of the latter, and adapted to bear against the outer side ot' the eccentric collar, substantially as and for the purpose set forth.

4. The combination of the base-plate have ing a central spindle and an eccentric cylindrical collar with the outer casing or covering,and an inverted-cup shaped revolving cylinder mounted upon the said spindle, vibrating gates hinged to the inner side ofthe revolving cylinder, a cutoff valve attached to the eccentric collar between suitable inlet and exit ports, and openings arranged to admit water under pressureto the spaces between the outer casing and the revolving cylinder and to the interior of the eccentric collar against the under side of the top of the said revolving cylinder, substantially as and for the purpose herein set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two Witnesses.
