lti .flgshilg nimh tu in these riteri `atrnt Vmit making nrt if flic slime.
'To ALL vvnoM 1T MAY ooNcERN:
Be it known that I, G. G. HUNT, of Bridgeport, in the county of. Fairfield, and State of "Connecticut, have i,
invented a new and improved SteamValve; and Il do hereby declare that the'followin'gis afull, clear`,i`a.nd exact description thereof, which will enable those skilled inthe art to make and use the same, reference'being had to the accompanying drawings, forming part of this specification, in which#- Figure 1 is a vertical central section of my invention, taken in the line z a', tig.` 2. Figure 2, a plan or top view of the same. Figure 3, a detached external view of the valve. V Figure 4,`a horizontal section of the device complete, taken in the line y y iig. 1.
Similar letters of' reference indicate corresponding parts.
This invention has for its object the construction of a valve in such Ya manner that it will serve as a perfect i regulator as regards the admission of steam to the cylinder of an engine, and admit `of the governor operating perfectly to regulate theadmission of steam when applied to an engine of any size and power.`
A represents a shell in whichthe valve is placed. This shell may be of cylindrical form, and' it `is secured ,i
on the steam chest of an engine, communicating with it by means of an opening,` a, in its bottom. The steam is admitted into the shell at its side, as shown at b,figs. l and 2. The valve is composed of two hollowicylinders, B D, tted one within the other, the outer one, B, at its upper end fitting over a circularflangac, at the u nder i side of the cap, E, of the shell, A, and its lower end tted inA a circular recess in `the bottom oi' the shell, `the cylinder, B, being ixed or stationary, and having a series of oblong slots, d, -inade circumferlentially in it.` i The l inner cylinder, D,'.is itted loosely in B, so that it may be turned therein, and also moved up and down gi and said cylinder, D, is also provided with slots, e, similar to the slots d in B-` The cylinder D hasa rod, F, attached to its upper end, and said rod passes up through a stuiliing-box, f, n the cap E of the shell A, the rod having` a horizontal arm, G, secured to it above the stuing-box', f, by a set'screw, g, which arin passes through a slotted i i plate, h, attached to the stuilingbox.4 This arm and slotted plate prevent `the inner cy'linder,D, fromturning casually. The rod F is connected `withan ordinary ball governor, which regulates the admission of steamlinto` the steam-chest by raising and loweringthe inner cylinder, D, so that `the slots e in D may register `in, a greater f or less degree with the slots d in B, the steam passing from thel shell through those slots into'D, and through i the lower end of 'D into the steam-chest through the opening, d, in theI bottom `off the shellr; `When the governorf l adjusts the cylinder D so that its slots, Ae, will register perfectly with the slotsd in B, the full amo'untof; steam i will passthrough` the valve. into the steam-chestV that the valve isv capable of having pass1through it; `thatwisfif i, the slots e d are in line with. each other, both vertically and horizontally; and in cases where a. lesssupplyof steam is required, the slots e ol are virtually contracted hy Vturning the innercylinder, D, the set-screwg o farm G being loosened for that purpose, and the slots e will be cut oi' in a greater or less defrree from the slots d: (See fig. 4.) By this simple arrangement the capacity of the valve may be variedas circumstances may require, and i l; the valve adapted to engines of various sizes and powers and' the valve is an extremely sensitive one, owing to r the steam being admitted through a plurality of openings, a very slight movement of the inner cylinder causngl a great variation in the amount of steam admitted. 4
Having thus described my invention, I claim as new, and desire tcrsecure by Letters Patent i The arm G, applied tothe valve-rod .F and secured, thereto by means of asetescrew, g, in connection with the slotted plate In, attached to the stuiii-ng-box f, substantially as and for the'purpose specified.
