lWl PROVEM ENT IN GAS-NI ETERS.

Specification forming part ol' Letters Patent No. 10.266, dated October' 13, 1863.

KROMSCHROEDER and JOHN FREDERICK GUsrAv KEonscHEoEDEn, both of Princess Terrace, Regents Park, in the county ot' Middlesex, England, subjects of the King ot'Hanover, have invented or discovered new and useful Improvements in the Manufacture otl Gas-Meters; and we, the said HENRY HER- MAN KRoMsoHRoEDEE and JOHN FEEDER- Icx GUs'rAv KRoMscHRoEDEa, do hereby declare the nature ot' the said invention and in what manner the same is to be performed to be particularly described and ascertained in and by the following statement thereofthat is to say This invention has for its object improvements in the manufacture of gas-meters.

In constructing the measuring-drum for a gas-meter it is formed of two concentric cylinders, and the annular space between them is divided into a series of similar measuringcompartments by partitions formed as hereinat'ter explained. It is preferred that the annular space should be divided into four measuring-compartments, but this is not essential. The water-line in the meter is somewhat below the upper part of the inner cylinder, and gas is admitted above the waterline into the interior Qt' the inner cylinder. There is a passage formed through the inner cylinder into each measuring-compartment, and such openings are immediately below the points where the partitions join the inner cylinder. In the outer cylinder there is an out-- let-passage formed above each partition for the passage of the gas out ot' the compartments when the lowest end of the compartment comes above the water-line in the meter. Interior of the central cylinder there is applied or formed a float to support or buoy up themeasuring-drum, but to which, separately, no claim is made.

Having thus stated the nature of our said invention, we will proceed to describe more fully the manner of performing the same.

In the drawings, Figure l shows an elevation ot' a .gas-meter, partly in section Fig. 2, a transverse section, and Fig. 3 a section through the measuringdrum.

In each of these 1i gures the same letters of reference are used to indicate the same parts.

ct a is the measuring-drum, which is con structed ot' two cylinders, the outer one, a a, and the inner one, a a. The annular space between these two cylinders is divided into four similar measuri11g-chambers by angular partitions a2 a2. The inner ends of the partitions a2 c2 are connected to the inner cylinder, a. The 'partitions u? a2, from the point where they are connected to the inner cylinder, proceed in a tangential or nearly taugential direction toward the outer cylinder, and then such partitions are bent to an angle, and then their outer edges or ends are connected with the outer cylinder, a a, thus produoin g peculiarly-formed angular measuringchambers around the inner cylinder, a a', as will readily be understood on examining Fig. 3 of the drawings. Interior of the cylinder aa is a hollow ioat, l) b, which is mounted on the same axis as the measuring-drum, and the measuring-drum is attached to such axis, c, by arms or spokes. The axis c ot the measuring-drum is carried by a lever-frame, d d, which is supported by lixed necks or axes c e. On the axis c ofthe measuring-drums is a cog-wheel, which takes into and drives the cog-wheel f, which revolves on one of the tixed necks or axes e e of the lever-frame d d. To the cog wheel fis xcd a bevel-toothed wheel, g, which takes into and drives a beveltoothed wheel, h, ixed on the axis t' of the counting apparatus, by which, notwithstandV ing the measuring-drum moving, the constant driving of the axis t' of the counting apparatus is insured.

j is the inlet or supply to the meter, through which the gas passes into the chamber 7c lc when the valve l is open, which it will be so long as the float m is supported by water in the chamber lo. The gas passes from the chamber lo through the pipe u into the chamber o, and also from the pipe n by a bent branch pipe, n, into the interior of the inner cylinder above the level of the water therein, and thence through the openings a3 into the measuring-chambers, from which the gas ows out at the openings a4 as they come above the water in the compartment of the meter in which the measuring-drum works, and thence by the outlet-pipe p.

The action of the meter is regulated by means of an inverted vessel, q, which is at one end of thele\f'erfraxne d d, and into which gas is conducted by the pipe o from the vlower chamber7 o, so that the gas in the inverted vessel g is at the same pressure as it is in the supply-chamber. The other end of the leverframe is Weighted and regulated or adjusted as heretofore when a similar frame and inverted vessel have been used.

Having thus described a gas-meter embodying our improvements, what We claim as our invention, and desire to secure by Letters Pat ent, is-

l. The combination, in a gas-meter, ot' an annular measuring-drum with an internal tloat to buoy up the drum in the liquid With which the meter is lled, substantially as dey scribed.

2. The combination of an annular measuringdrum and float, constituting a Heating measuring' drum, with a lever-frame connecting the axis ot' the drum with fixed necks or axes which are in line with the axis ot' one ot' the wheels of the counting apparatus, so

.that the floating measuring-drum acts uni- H. H. KROMSUHROEDER. J. F. Gr. KROMSCHROEDER.
