IMPROVEMENT in .VALVE-PLUGS.

I ASpecification forming part of Letters Patent No. 150,343, dated AprilQB, 1874; application filed January 2S, 1874..l

To all whom it may concern.'

- Be it known that I,` Ezm MILLER, of N ew York, in the county of New York and State of New York, have invented. a new and valuable Improvement in Valve-Plugs; andl I do herebydeclare that the following is a full, clear,

vand exact description of the construction and .of a vertical sectional view of my valve'- plug.

Figs. 2 and 3 are side elevations of the same. Figs. 4, 5, and G are horizontal sections of the same.

l This invention has relation to a'valve or cock plug which is applicable tomy improved Water-registering apparatus, for which application for Letters Iatent of the United States was made by me on the 3d day ofA J anuary, A.

The object of my present invention is to so construct the valve or cock plug above referred'toiliat, while it serves thepurpose of regulating the flow of water throughthe main pipe and registering mechanism, it will' auto- '.niatically prevent any sudden check or variation in the force of Water in the main frommaterially influencing the said registering mechanism, as will be hereinafter explained.

The following is a description of my improved valve or' cock plug: In the annexed drawings, A designates the main pipe, 'to which the cock-plug l?, is applied, and C C designate two branch pipes, one of which, C,'leads to a .registering mechanism, (not necessary to be represented in the drawing-Q and the other pipe, C, leads from said mechanism back again into the pipe A. The cock-plug B is located in the pipe A between the ends of the pipes C C', and is constructed with three ports, e e162, below a valve-seat diaphragm, j', and also with two ports g g, above this diaphragm. When the two ports e e1 are fully in line with the main pipe A, water will not ilow through the pipes which lead to and from the registering mechanism; but

` Caen B.

through the branch pipes.

by turning thecock about its 'axis more or less, any desired amount of the Water may be di: verted from a direct course through the main pipe, andcaused to'ow through the pipes U C. When this latter adjustment ismade the port ezfwill be more. or less exposed in line with lthe main pipe Afand when' this port d `isadjusted fully into line with the main pipe` all the water from the latter will be diverted Above the diaphragm f the plug B is chambcred, to receive a valve,vh., a spring, t', and an adjustable nut,

j, which latter is on a screw-threaded valve.- stein, h. The valve. h is seated on the diaprevented from turning by means of shortI Wings on it, which are received Ainto .grooves made vertically into the bore of the plug 1?.

rhe valve-stem h passes through the cap B-l ofthe plug B, @Dd through a packing suitably applied thereto, and it. has a prismatic head for receiving a turn-key, by means of which the pressure of the spring s on the valve h can be `nicely adjusted. Valve his applied loosely' o'n' its stein. The objectv of the yielding valve is to prevent any sudden increase in the dowof Water through the main pipe A from react- I1ng,*to any great degree, on the registering mechanism, for, should a sudden shoc'kgoccur in the main pipc, the valve h will rise, and allow a quantity of water to pass through the plug l5 above the diaphragm, and thence through .the ports g g, and thusmodifying the shock. v

I do not under this application claim a registering mechanism combined with the' im.- proved regulatingcock, as such mechanism forms the subject of my application for a patent filed January 3, 1874, and. above .ifea

ferred to.

AWhat I claim as new, and desire .to secure by Letters `Patent, is

1. A valve-plug havinga diaphragm, f, with -yiclding relief-valve, and below the same both entry an-ext' povtsfo opposite YHsi 1es fand' In tstim'ony'that I 'claim ,the above I have above the sameqeziblponts. bnly, substantilly Yhereunto subscribed my name in the presence asspeeiied. of two witnesses.
