, ence being had to the accompanying drawquick acting in its 0 ings, forming part of this specification.

My invention relates generally to vapor, vacuum and steam heating systems and more particularly to a valve for controlling the flow of steam or vapor from the supply pipe to the radiator, the principal objects of my invention being to provide a comparatively simple inexpensive supply valve which can be utilized in connection with practically all vapor, vacuum and steam heating systems now in general use; to provide a valve which can be accurately regulated and set so as to accurately control the flow of vapor or steam to the radiator; to provide a valve which is and closing movements, and to provide a valve having a tapered ground joint between the valve stem and valve housing, which joint is absolutely air and water tight under all conditions, thereby doing away with the necessity of packing the valve at intervals for the purpose of overcoming leaks which invariably develop where valves are packed with leather, rubber, fibrous material or the like.

With the foregoing and other objects in view, my invention consists in certain novel features of construction and arrangement of parts, hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which Figure 1 is alan view of a supply valve of my improve construction.

Fig. 2 is a vertical section taken through the center of my improved valve.

Fig. .3 is an enlarged horizontal section taken on the line 33 of Fig. 2.

Fig. 4 is a aperspective view of the underside of the v ve head or body. r

. As illustrated in the accompanying drawings, the housing of my improved valve is formed in two parts, the lower part 10 being hollow and provided with a depending tubular portion 11 which is connected in any suitable manner to a vapor or steam supply pipe 12.

Formed within the hollow body 10 immedlately above the member 11 is ahorizontally disposed annular flange 13, the to of which forms a: valve seat. Leading om one side of the hollow body 10 is a tubular member 14 and connected thereto in any suitable manner is a nipple 15, the outer end of which is adapted to be connected to a radiator. The upper end of the hollow body 10 is internally threaded and receives the lower end of a vertically disposed member 16, the same forming the upper portion of the valve housing. The upper end of this member 16 terminates in a hollow cylindrical portion upon-which is adjustably positioned a disk, hereinafter more fully described.

Formed within the upper member 16 of the valve housin is a tapered opening 17, the surface of w 'ch is preferably ground so as to serve as aseat for aconical member 18, which latter is formed on the central portion of a valve stem 19. The n per portion of this valve stem extends t rough a gland nut 20 which is screw-seated in a chamber formed in the upper end of member 16 and located in said chamber below the gland nut is suitable packing 21.

Positioned on the hollow cylindrical portion at the upper 'end of member 16 of the valve housing and removably held thereupon by means of a set screw 22 is a disk 23, the outer portion of which curves gradually downward toward its edge and appearing on top of this disk on opposite sides of the set screw 22- are the words Closed and Open, and between these words appear the designations i, and 2. These words and designating numerals serve as guides for positioning the valve handle so that the valve within the housing 10 and hereinafter more fully described, may be set in open or closed position or at predetermined points between full open or closed positions.

By curving the top of the disk 23, the

designating marks on the top thereof can be of the valve. Consequently, it is not necessary for a person manipulating the valve to get in position where the eyes are directly above the disk as would be the case if the top of said disk were made perfectly fiat.

The upper end of valve stem 19 receives an operating handle '24, the inner end of which is provided with a downwardly bent finger 25, the lower end of which travels in a path directly above the designations on the top of disk 23.

The head or body of the valve comprises a cup-shaped member 26, in the underside of which is seated a ring 27 of comparatively soft metal, composition or fiber, and when the valve is closed, the underside of this ring rests directly upon valve seat 13.

Fixed in any suitable manner to the underside of valve head 26 is an inverted cupshaped member 28, in the wall of which is formed one or more vertically disposed slots 29. l/Vhen valve 26 is raised, ring 27 is lifted from seat 13 and the upper ends of the slots 29 in member 28 serve as ports through which vapor or steam passes from the chamber below the valve seat into the chamber above said seat. v

That portion of the valve stem below the conical body 18 is made square or non-circular as designated by 30, and this portion tits in a recess or openin 31, the latter being formed in a vertically disposed member 32. The upper end of this member is provided with a double or quick-acting thread which engages a corresponding thread formed in the lower end of upper member 16 of the valve housing. The lower end of member 32 is provided with a flange 33 which is loosely positioned in valve head 26 and held therein by a ring 3%, the latter being screw-seated in said valve head 26.

'lhe non-circular opening or recess 31. in member 32 is slightly larger than the portion 30 of the valve stem, thus permitting said stem to be shifted a short distance before engaging and imparting movement to said part 82.

l have demonstrated in practice that this construction causes the valve to operate easily and without any tendency to stick at the beginning of either opening or closing movements. i

As handle 24- is shifted so as to move finger 25, from the point marked Closed on the disk 23 to the point marked (Pp-en or vice versa, valve stem 19 will be rotated in the upper member 16 of valve housing, and as the lower non-circular portion 30 of said stem is thus rotated, corresponding rotary motion will be imparted to member 32with the result that the latter will move vertically simultaneously with its rotary movement, which vertical movement is due to the threaded engagement which said member 32 has with the lower portion oi housing 16.

neevaee with the result that steam or vapor will pass from supply pipe 12 through the lower portion or the housing and discharge through nipple 15 into the radiator.

A reverse movement of handle 24L will bring about a downward movement of valve head or body 26, with the result that the upper ends of slots 29 pass below seat 13 and ring 27 reengages upon the 'valve seat, thus cutting 0d the passage of steam or vapor through the valve.

Conical member 18 always fits snugly on its conical seat 17 and. this construction, together with the construction involving the threaded engagement of member 32 with the lower end of housing 16 edectually prevents lemage of steam or vapor upwardly through the valve housing.

The handle 24- can be shifted in position to various points between the full open and closed positions, thereby accurately regulating and controlling the fiow of steam or vapor through the valve.

A valve of my improved construction is' comparatively simple, can be easily and cheaply manufactured, can be readily assembled or taken apart, is constructed so as to entirely eliminate pachn from time to time to overcome leakage, an can be advantageously and effectively used in connection with all forms of vaponvacuum and steam heatsystems. I

lit will be readily understood that minor changes in the size, form and construction of the various parts of my improved valve can be made and substituted for those here in shown and described, without departing from the spirit or my invention, the scope of which is set forth in the appended claim.

I claim:

The combination with a supply valve housing having a vertically disposed cylindrical portion at its upper end, of a disk mounted on said cylindrical portion near the upper end of the latter and capable of being moved vertically or rotated upon the cyllndrical portion of said housing so as to be adjusted in position, a set screw passing'through said disk and adapted to engage the cylindrical portion of the housing for locking said disk in its ad usted position, the outer portion or which disk is curved gradually downward,

the top of said disk being provided with guiding marks, a valve operating handle ar ranged above and close to said disk, and a short guide finger formed integral with the signature in the presence of two witnesses, inner e123 of said fiandlle, which1 guidei1 finger this 1st day of November, 1916. is curv gra 11a y ownwar so t at its lower outer end travels in a path directly LEWIS OSTRAND-ER' 5 above the guiding marks on the top of the Witnesses:

disk, but leaves said marks always ex osed. M. P. SMITH,

In testimony whereof I hereunto x my M.,A. HONDEL.
