Be it known that L'JQHN I. OAPPON, a. citizen of the United States, and resident of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Pressure-Regulating Valves, of which the'following, taken in connection with the accompanying drawings, is a full, clear, and exact'description.
This invention relates to the class of valves which are designed to be applied topipes conducting either water or oilor gas or air.
The object of the invention is to provide a valve which shall be inexpensive in its construction, efficient in operation and adjustable to vary to a redetermined degree the stance through the pipe and thus regulate the pressure of said substance in its issue from the valve. And to that end the invention consists in the novel construction of the valve as hereinafter described and shown in the accompanying drawings, in,which Figure 1. is a'central longitudinal section of a valve embodying my invention; Fig.
2. is a top plan view of the same; and Fig.-
3 is a face view of the discharge end of the valve.
a denotes the valve-cage which is formed with the inlet b and outlet 0 arranged at diametrically opposite sides of the valve-cage. The interior of said valve-cage is formed with a central depression -cZ-- which communicates directly with the inlet b above said depression, the valve-cage is formed with a tubular projection e axially at right angles to the aforesaid inlet and outlet, and the upper end of the projection has an exterior wrenchhold surface e. The-lower end portion of said projecti'onextends partially into depressed por- .-tion d and has its interior formed with a downwardly tapering valve seat The upper end portion of the projection eis screw threaded internally and has has an outwardly projecting annular flange 9 adapted to seat on the top of the projection 6.
-h represents the. valve which is taof the plug g which holdsthe valve down-closely to its seat f and properly positioned when the flange g is firmly seated engaging the pro'ection -e'. The plug g has a wrench old exterior surface g" above the annular flange g.
The valve is formed with a central cavity extending throu h' the bottom or inner end of the valve. he wall of this cavity is formed with a pluralit of ports t--t which are distribute circumferentially in the wall and are of varying sizes arranged pro es'sively.' The outlet c of the cage isocated above the depression -d to allow the ports, one at a time, to communicate with the said outlet.
Z representsv a handle which is fastened, as at -u,-, to theupper end of the spindle n,- formed on the upper end of the valve and passing through the cylindrical' bore '0 of the plug g and bears upon the top of said plug. This handle has projecting from one end thereof a pointer owhich is disposed to traverse an index smarked on the marginal portion -ofthe top of the projection e as shown in Fig. 2 of the drawing Said index consists of numerals distributed circumferentially around the top of the projection 6, adjacent the flange g of the plug g. and are in positions corresponding to the location of the different ports .tt' of the valve. v
In using the described valve, the operator turns the valve h by means of the handle l which he leaves in a position which causes the pointer r to register with the special numeral of the index -sindicating the position of the desired port t registering with the outlet 0 thus obtaining the desired volume of substance escaping from the valveand controlling the pressure of said substance on the pipe conaxially at right angles to said inlet and outlet and having its inner end portion extending into the aforesaid depression between the inlet and outlet, directing a partially obstructed passage therebetween, and formed with a tapered valve seat in its interior, and havin the outer end portion thereof screwthrea ed internally, and a wrench hold surface on the outside thereof a valve formed a with a reduced outwardly extending spindle and having an annular shoulder, the interior of said valve being formed with a cavity extending through the inner end of the valve and communicating with the said depression, the wall of said cavity being provided with a plurality of ports of varying sizes progressively arranged, and distributed to communicate one at a time with said outlets, a tubular plug, said plug screw-threaded exend of the spindle and contacting the top of the plug and provided with an extension forming-a down-turned ointer, an index on the to of the aforesai projection circum- -.ferent1ally arran ed adjacent said flange,
and the passage 0 a fluid through said inlet adapted to impel said valve from said seat and toward said plu as fully set forth.
