DRY GAS-METER.
SPECIFICATION forming part of Letters Patent No. 247,733, dated September 27, 1881.
Application filed June 29, 1881.
To all whom it may concern..-
Be it known that I, JOHN FOXALL, a citizen of the Kingdom of Great Britain, residing at Newport, in the county of Monmouth, England, have invented certain new and useful Improvements in Gas-Meters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled i n the art to which it apper- IO tains to make and use the same, reference being had to the accompanying drawings, and to the letters or figures of reference marked thereon, which form a part of this specification.
This invention relates to certain improve- I 5 ments in dry gas-meters; and it has for its ob- ,ject to provide a meter which will register more accurately and give a more steady and uniform light than heretofore. These objects I attain by the apparatus illustrated in the accom pan ying drawings, in which- Figure 1 represents a transverse vertical section of my improved meter. Fig. 2 represents a top view with. portions broken away, showin g the interior mechanism. Fig. 3 represents a detached view, showing the valve-ports for the induction and eduction of the gas; Fig. 4, a detached View, showing the passages leading from the bellows at each side of the diaphragm to the eduction-tube of the meter. Fig. 5 is a reverse view of the valve; and Fig. 6 is aside elevation, partly in section.
The letterA indicates a casing of sheet metal, which is preferably rectangular, but which may be made in any other desired shape. The said casing is divided into three compartments, B, O, and D, by means of the vertical diaphragm E and the horizontal partition F. In the com-v partment D is located a chamber, G, into which extends and with which communicates the gas induction pipe H. The said chamber is provided with the ports I, K, L, M, and P, as clearly shown in Fig. 3 of the drawings, the ports I and K leading directlyinto the compartments B and O at each side of the vertical diaphragm. 5 The ports L and M connect, by means of passages R and S and apertures T and U, with the interior of the bellows or flexible chambers V and V, located, respectively, in the compartments B and O. The central port, P, leads to a vice-pipe Y of the apparatus. The gas comes (Modeh) Patented in England July 23, 1880.
in theinduction-pipe H and fills the chamber G. When the open part 0 of the valve A is over the port L the gas passes through it into the passage S and opening Uinto the bellows V, causing it to expand. This motion is comma nicated to the valve A,causing it to rotate and place the open part 0 over M. Then the gas is out off in its passage into V, and passes through port M, passage R, and opening T into bellows V, causing it to expand. Thus the alternate motion is kept up. When the open part 0 of the valve A is over L the exhaustrecess D is over K, which is open to compartment B, and the gas contained in it flows into 6 the central port, P, and thence out through W to the exit-pipeY; and when the part 0 is over M the exhaust-recess D is over I, which communicates with compartment A, and the gas contained therein escapes into the central port, 7: P, and thence outward, through W, into the exit-pipe Y.
The letter A indicates a rotary valve, which is located and adapted to move upon a seat, B, formed around the ports I, K, L, M, and P. The said valve is in the form of a disk, cut away at the edge to the extent of one of the" ports above mentioned, as indicated by the letter 0, and having a recess, 1), on its under side. I The valve on said under surface is provided with a packing of leather or other equivalent material, as indicated by the letter F.
The letter G indicates a valve-stem secured to the rotary valve and passing upward through a stuffing-box, H, the outer extremity being provided with a worm-screw, I, which intermeshes with suitable gearing connected with an index or pointer, to indicate, in connection with a suitable dial, the quantity of gas passed through the apparatus. The said valve-stem, 0 at its outer or upperend, is provided with ahorizontal crank, K, to which are pivoted the connecting-rods L, which are in turn pivoted to the arms M, secured to the vertical rods N, passing through stuffing-boxes O, the lower 5 ends of said rods connecting with the respective bellows or flexible chambers by means of the arms N It will thus be seen that, as the bellows are alternately expanded and contracted, they communicate motion to the verti- I00 cal rods N through the arms N and the rods N in turn operate the arms M. Up to this flexible chambers to the central port of the valve connecting with the eduction-port of the meter, substantially as and for the purposes speclfietl.
2. The combination, in a gas-meter divided into three compartments, of the bellows, the induction-chamber and its ports, the rotary valve and its valve-stem, and mechanism for operating a register, and the ednction-pipe connecting the central port of the valve with the exit-pipe, substantially as and for the purposes In testimony whereof I aflix my signature in presence of two witnesses.
