IMPROVEMENT IN METERS.

The Schedule referred to in these- Letters Patent and making part of the same To all whom. it may concern:

-Be it known iliat I, GEORGE SEWELL, ot' Brooklyn, in the county of `Kingsand State of New York,

have made certain new and useful Improvements in Apparatus for Measuring Water, and other Liquids; I hereby declare the following to be a full and p exact description of the same, `reference being had to the annexed drawing which forms part of this sinecilica-l Figure 1 is a plan view, partly in section, showing the interior ofthe apparatus; -and Figure 2 isa similar vertical sect-ion.

The same letters indicate like parts in both figures.

My invention consists in certain l'improvements in water-meters of the kind described in patent No. 7,075, issued to William Sewell, February 5, 1850.

Description. of the Apparatus,

The vouter cylinder or case A A has thc inner drum i 4 connects with the channel E E, which is a brauch from vthe induction-pipe Il, so as to admit the liquid, and,

by hydrostatic pressi11"e, toactagainst'the endsof the wings F F, and keepthem pressed against the inner walls of case A as drurnB B revolves.

Herctofore, it has been usual to employ a spring to keep the wings against the cylinder A. Butvmy arrangementby hydrostatic' pressure through thechan`- nel E E D, gives a steady uniform pressure, so as to keep the wings always pressed against the walls of case A. Only two wings are necessary,'.but it is ob-v vous that a largerhumber may be employed, all operated by the hydrostatic pressure in channel E E l).

That the wings F Fmay move water-tight in their channels, they are packed.

G is the follower to packing H H', on the ends of the-wingsF F, and

.I -is follower to packing on stufling-box shaft P, which carries a bevel-gear to connect with any suitaregiste1'ing-1-levice, such as Ordinarily used for that purpose.

' The registering devices are inclosed in a box with glass cover, N, and bottom K K, which form the top of case A A. v

`Gl'annels, hh and g g, are formed between the moving parts, for the purpose of water-packing.

71' is packing between the cylinders A A and B B, at their tangent-point, In .Order to form a greater bearing-surface at this point, the cylinder A A is cut awayas'lshown, so that these cylinders are in contactfor more than the distance between the grooves g y,

on both sides of packing h'.

NVhcn the wings F are just pastthe entrance L, there would not be suticient pressure to keep the. wings inoving.v Therefore, to continue the pressure on both wings, a. groove or channel, m m, is formed on the inside of the walls of A A, near L, so as to admit thefull pressure ot'- water to both wings for any desired distance, thereby securing certainty of action in the revolving cylinder B B.

Having thus described my invention,

What I claim, and desire to secure by Letters Pati ent of the United States, isi 1. The channel E E from induction-pipe L to hol low gudgeon I), so as to keep thewings F F extended, and iu contact with cylinder A Aby means of liquid pressure, substantially as set forth' and dep scribed.

.2. 'The groove or channel mim, so as to admit the 'fullWater-pressure to both wings, as and furthe purpose set forth.
