VALVE.

T all whom it may concern Be it-known that I, WILLIAM J. SHARKEY, a citizen of United States of America, residing at Pine Bluff, in the county of Jefferson and State of'Arkansas, have'inv'ented new and useful Improvements in Valves, of

which the following is a specification.

This invention relates to locomotive throttle valves, and aims to provide a construction which is easy of manipulation,

and one which need not be removed from the stand pipe to permit inspection of the boiler.

Valves for the above mentioned purpos with which I am familiar, include an elbow which must be removedfrom' the steam dome to permit inspection of the boiler,

and this obviously requires considerabletimeand labor. My purpose, is to construct a valve to eliminate this trouble.

An important, object of the invention, resides in the simplicity of the construction of the valve, thusfutilizing less material,

and occupying less room=when in position for use, than throttle valves in present day use. J J

v The nature and advantages of the'inven .tion will be better understood when the following detail description is read in connection with the accompany ng drawings, the lnvention' residing in the 'constructlon,

" combination and arrangement of parts as claimed.

In the drawings forming-part of this application, like numerals of reference indicate similar parts in the several views, and wherein Figure 1 is a view in elevation of the valve constructed in accordance with my invention, showing the valve associated with the stand pipe of a locomotive.

Fig. 2 is a vertical sectional view taken 0 line 2-2 of Fig. 3.

Specification of Letters Patent.

Patented Mar. 29,1921. Application filed June a, 1920. Serial no. 387,417.

base having an enlarged central opening 11 =1 about the ed e of which rises a short annular flange 12. ii. plurality of standards 13 project upwardly and inwardly from the wall of the opening 11 of the base, and support of smaller diameter than the base 10, and spaced therefrom the desired distance. Arranged upon the plate" 14 {are crossed guide elements 15 for the valve B, these elements being secured tothe top in any suitable manner and in the form of strips arranged '60 on their upper ends, a top plate 14.which is edgewise, and of a length substantially equal to the diameterof the upper side of topplate 14. Both the flange 12 I and the top plate 14, are beveled as at 16, thus'p rovidber of a size to fit nicely overthe cage A,

the valve having inwardly directed upper andlowerflanges 1 8. The'inner periphery of each flange is provided with a straight portion or-edge 19, anda-beveledportion 20 so that the valve17 readily accommodates edge or portions 19* cooperate with the standards 13 andwith the guiding elements l5'to 'm'aintaina proper position with respect to the valve seat when thevalve is itself to the valve vseats16. The straight moved to an open position. The valve 17 is also provided with an annular groove 21 arranged intermediate its ends, to accommodate the valve operating means of well known construction.

In practice, the valve 17 is raised and lowered to an opened and closed position in the usual well known manner, and when the valve is in an opened position as shown in Fig. 4, the steam enters thepipe atboth the top and bottom of the valve, as indicated by the arrows in Fig. 4. When the valve'is elevated to an open position, the. straight edges 19 at the bottom of the valve contact the adjacentedges of the standards 18, while the straight edges ofthe upper end of the valve contact the adjacent edges of the guiding elements 15, and in this mannerthe valve is maintained in proper position with regard to the valve seats 16 so as to properly and effectively engage the seats when the valve is lowered. The construction obviously eliminates the elbow hereinabove referred to in connection with other valves of this type and could be readily substituted for this type of valve without any change in the construction of the pipe with whlch it i is associated. The simplicity of the construction is such that it occupies but a small amount of space, and also provides for inspection of the boiler without removing the valve from the pipe. I desire to have it nnderstood that the valve can be varied in size and configuration without departing from the spirit of the invention.

While it is believedthat from the foregoing description,the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to the details herein shownand described and that such changes eled portions to normally engage said seats,

and: said valve having an annular groove intermediateits ends for, the: purpose specifled. I
