ROTARY METER.

SPECIFICATION forming part of Letters Patent No. 298,230, dated May 6, 1884.

Application filed September 1,51883. (No model.) l

To all whom it may concern.'

Be it known that I, JOHN A. PEER, of Grass Valley, in the county of Nevada and State of California, have invented a certain new and useful Improvement in Meters, also applicable tok Motors and Pumps, of .which the following is a specication. v

The nature of this improvement will be fully described, and then pointed out in the claims.

In the accompanying drawings, Figure l isV a section of an article embodyingy my improvement, taken transversely to the axis; and Fig. 2 is a section of the same taken parallel with the itXlS.

Similar letters of reference designate corresponding parts in both iigures.

A A A2 designate the case of the article, consisting, as here shown, of a cylindrical shell, A, and heads A A2. The shell and heads are shown as having radially-extending fianges secured by screws. Any suitable packings may be employed to preclude leakage between these parts. The head A is provided with an outwardly-extending cylindrical neck, A3, onto the exterior of which is secured a frame, B, and the head A2 is provided with a cylindric shell, A4, that extends inwardly into the shell A almost to the head A. This head A2 also is provided with an outwardly-extending air-chamber,V. The shell A4 is provided with holes a throughout about one-half of its The air chamber ,V is provided with an Outlet, a- The lower portion of the shell A is provided with a tangential inlet tube or passage, A5, that may be formed therewith, or made separately and screwed thereto, so as to communicate with an opening through the shell. The fluid which is to be passed through the case enters through the inlet-tube A5, and escapes from the said case through the holes a into the shell A4, and thence through the hole a of the air-chamber A4. If the iiuid is to be saved, the hole ce of the air-chamber V may be connected with any suitable conduit or reservoir.

C is a rotary shaft, which, as here shown, is journaled at one end in a hollow screw, D, insei-ted in the outer end of the frame B, and at the other end in a hollow screw, D', inserted in the outer side of the .air-chamber V. The.

shaft O has affixed to it a wheel, E E E2 E3,

consisting of two heads, E E', and two series of blades or buckets, E2 E3. The` buckets E2 extend at an angle both to the radii and circumference of the heads of the wheel inward a short distance from the circumference of these heads. The buckets E3 extend from a point close to the inner ends of the buckets E3 close to the shell A4. The buckets E2 will preferably be curved, but may be approxi- 6o mately straight from end to end. The buckets E3 are shown as curved eccentrically to the heads of the wheel and to the shells A A4. A cylindric shell, A3, extends fromV the head A2 between the buckets E2 E3, and into a 65 groove, c, in the head E of the wheel. It may be made separately from the head A2, and secured thereto by screws or otherwise. In the upper portion it is provided with a hole, d. The outer ends of the buckets E3 7o extend close to the shell A.v llhe wheel has a hub, E4, that` extends into the neck A3 of the head A. The neck A3 is provided at the outer Vend with a cap, A3, that closes it. It may be advantageously provided ywith a stufling-box, through which the shaft C will pass.

All the parts described may be made of metal.

Preferably the inlet-tube A5 will be provided with a cock, e, for regulating the quan- 8o tity of fluid passing through it. Fluid entering the inlet-tube A5 passes into the case, and, acting against the buckets E2, imparts motion to the wheel.` Moving in contact with these buckets, and between the shellA and the shell A3, it finally reaches the opening d ofthe shell A3. Passing through this opening,it comes in contact with the buckets E3, thereby imparting an additional impetus to the wheel. After acting against the buckets E3, it enters the shell 9o A4, and escapes through the same. By passing fluid under pressure thus through the article described, it will be measured, and will render the article useful as a motor. If the wheel be rotated by power applied to its shaft, fluid will be pumped through the article. Obviously the article is therefore a meter, a motor, or a pump, according to the manner in which it is used.

When the apparatus is to be used as a meter, Ioo the shaft C may be provided with an index, forming part of a registering apparatus, or

with a bevel-wheel that may engage with another bevel-wheel on the shaft of the index of a registering apparatus. The registering apparatus may be ot'any well-known character.

5 Vhen the apparatus is to be used as a pump,

motion maybe imparted to the shaft C by belt or other gearing.

Vhen an index is to be operated, the shaft of the index may extend a considerable dis- Io tance from the meter-as, for instance, from a cellar to a sidewalk above it.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a meter, motor, or pump, the combirs nation of a case, a wheel adapted to rotate within the same, and having two sets of buckets, a cylindrie shell extending between the two sets of buckets of the wheel, and having an opening through which fluid may pass from 2o the outer set of buckets to the inner set of buckets, and an outlet from that portion of the case which is surrounded by the inner set of buckets, substantially as specified.

2. In a meter, motor, or pump, the combi- 25 nation of a case, a wheel adapted to rotate within the same, and having two sets of buckets, a cylindric shell extending between the two sets of buckets of the wheel, and having an openin g through which iiuid may pass from the outer set of buckets to the inner set of 3o buckets, and a shell extending into the central part of the case and serving to convey away iiuid therefrom, substantially as specified.

3. In a meter, motor, or pump, the combination of a case having a tangential inlet tube 35 or passage communicating with the lower portion, a wheel adapted to rotate within the case, and having two sets of buckets, a cylindric shell extending between the outer set of buckets and the inner set of buckets of the wheel, 4o and having an opening through which iluid may pass from the outer set of buckets to the inner set of buckets, and an outlet from that portion of the case which is surrounded by thev inner set of buckets, substantially as 45 specified.
