cits-REGULATOR.

Specification of Letters Patent No. 5,300, dated September 18, 1847.

To all whom it may concern Be it known that I, JOSEP BATTIN, of the city of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in the Manner of Disfrom Gasotributing Illuminating-Gas meters used at Gas-Works; by which improvement I am enabled to regulate the pressure by which the distributer is effected more perfectly and economically than by any of the methods heretofore practiced for that purpose, and I do hereby declare that the following is a full and exact description thereof. I

In the distribution of illuminating gas by the means heretofore adopted, it has'been found extremely diflicult to equalize the pressure in the pipes of distribution; when the supply is too small there is, of course, a diminution of the light which the'burners ought to give out, and when the pressure is too great, the gas meters are caused to overflow, by which they are rendered unfit for use, until they are again supplied with water.

The gas is forced through the distribution pipes by its own elasticity, as it is received from the generators, and by the descent of the upper, or floating; vessel of the gasometer, the weight of which is counterpoised to such extent as to allow it to have a descending power which shall'approxi mate as nearly as may be to that required for the distribution; but, from various causes, this weight is liable to vary in its action, and does not sufiice to produce the desired efiect, as is well known to those fa-' miliar with gas Works.

It has been attempted to regulate the flow of gas by placing a man to turn a wheel having an apparatus appended to it de-= signed to equalize the flow, but this plan was soon abandoned; more recently a conical self acting governor has been introduced, which has partially obviated the difficulty stated; this self acting governor I will presently describe, as I employ it in my improved mode of constructing the regulating apparatus; but I have combined with it a mercurial seal, by which the self regulation is rendered efiicient; my improvement removing the defect of an imperfect stoppage of the supply when the pressure is such as to require it. It was not, in fact, found possible so to construct this regulator as to effectually out off the supply of gas, ;when it was requisite so to do, until the jmercurial seal was combined therewith by :me.

Int-heaccompanying drawing Figure 1,

{is a sectional view of, a gasometer, taken iverticallythrough its center, and represent: ing my improvement in the manner of regulating the pressure in the distributionof gas. Fig. 2, is a separate view of my imgPIOVBd governor or regulator.

A,is the tank, or Outer vessel, of the gasometer, and B, its floating vessel, suspended and 'counterpoised by weights in the usual manner, as shown at G. Fromthe floating vessel B, is suspended, by the rod C, the

conical regulating valve C; which is allowed to work up and down within the cylindrical space E, with the rising and falling of the vessel B. The space E, constitutes a part of the inlet pipe E, through which the gasometer is to be supplied.

F, is the outlet pipe communicating with the street mains.

D, is a cap or cover, adaptedto the enlarged part E, of the inlet pipe. This cap is furnished with a descending rim a, a, that is intended to pass into an annular mercury cup '6, b, that surrounds the conical regulating valve at its lower end. The conical valve, or regulator C, has been used without the mercury cup, and has to a certain extent, been found useful; but it is a polnt of greatimportance to be able perfectly to arrest the flow of gas into the gasometer when ithas become filled, as

otherwise the weight of the floating vessel andthat 'of'the elastic force with which the gas enters are combined in forcingthe said gas into the outlet and distributing pipes, and the meters are liable to overflow. In a large and cumbrous apparatus, like that.

of the gasometer used at gas works, it was i not found possible effectually to close the communication between the floating vessel and the inlet pipe by means of a valve; but

tained the desired end.

" The improved apparatus above described may be consideredas a miniature gasometer, with the cone regulator and quicksilver by combining the mercury cup, or seal, with theconicalvalve or regulator C, I have atcounter weights of the gasometer have been duly regulated so as to give the desired pressure, and the influx of gas has beensuch as to fill the gasometer, the conical regulator will be raised so as to bring the quicksilver seal into action, and thereby the further inflow of gas will be prevented, until the vessel B, of the gasometer again begins to descend; the inflow of gas will" then take place around the base of the conical valve, or regulator, but the space through which it passes will be comparatively small, but with its descent the space around the conical valve will be increased, and the generated gas will enter more fully. As the gas again passes the regulating cone or governor, and the pressure within the gasometer is sufliciently increased, it will again rise, until the communication is closed by the quicksilver seal, and all increase of pressure will be prevented.

Having thus fully described the nature of my improvement in the manner of regulating the, distribution of the gas from a gasometer, what I claim thereinas new, and desire to secure by Letters Patent, is-

- The manner herein set forth of combin- I do not make claim to either of these de vices when taken separately, and uncom bined with the gasometer and inlet pipe, but I limit my claim, exclusively, to the aforesaid combination, for the purpose here-n in fully made known. V
