VALVE.

' Speciaation of Iiettersratent, Patented Dec. 21, 1909.

Application filed April 22, 1909. Serial No. 491,481.

Be it known that 1 WILLIAM a citizen of the'United States, residing at Chester,.in the county of Delaware, State of Pennsylvania, have invented a new and use.-

ful Valve, of which the following is a speci-l fication.

My invention relates to packless vapor and other valves and consists of novel means for automatically taking up the. wearbn the valve plug, so asA to roduce at all times a perfectly tight joint etween the'plug and l its casing at points where' leakage is to be avoided. n

It also `consists of novel Ameans for locking the valve plug in variouspositions whereby more or less vapor, steam or other heating medium may -be introduced into the radiator columns, when myinvention is applied thereto.

For the purpose of illustrating my invention I have shown in the accompanying drawings one form thereof which is at present` preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that thevarious instrumentalities of which my invention consists can be variously arranged and-organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

-Figure 1 represents a front elevation of a i valve embodyln my invention. Fig. 2 represents a vertica section of the valve seen 1n Fig. 1. Fig. 3 re resentsl a vertical section of the valve in w ich the inlet and outlet openings are in different positions from. the corresponding ones seen 1n Fig. 2. Fig.l 4 represents a horizontal section on line -w, Fig. 1 on an enlarged scale. Fig. 5 represents a plan of certain of the parts seen in Fig. 1. Fig. 6 represents in elevation, a portion of the rotating valve body. Fig. 7 represents a horizontal section on line y-y 1n Fig. 6. Fig. 8 represents a horizontal secs tion of a portion of the plug and casing in assembled position. Similar numerals of reference indicate corres onding parts in thefigures. I

eferring to the drawings -1 designates the casing or shell of my novel valve, the same having preferably formed therein a artition 2 provided with perforations 2".

orining a communication between the in terior of the said casing and an vopening 3,

T. FoWDEu,l

coperate with a similar facebf a part to be later described and adjacent which face 5 are screw threads 6 adapted to engage screw threads 7 in a bushing or cap 8 forming a closure for one end ofthe casing 1.

The casing 1 is preferably 'screw threaded at 9^to recelve the screw'threaded cap 10, which retains 'a member 11 firmly in position with respect to the casing 1. This nmember 11 is. provided with a ground face 12, whichengages a similar face 13. in the casing 1 to form a joint, it being noted that said member 11 is provided with a collarl 14 member 11 and casing Y The member 11 is referably threaded at 15 to provide means or securing said memtained in contact therewith by means of a spring 22 or the like, which in the present instance tits within the bushing or ca 8 and encircles the stem 21, one end of whic bears against the top of the valve 16, while its opposite end bears, as at 23, against the bus 111g 8, whereupon the tension of said spring upon the .valve 16 causes the latter to fit tightlyl upon the casing 1.

19 designates a flange on the casing 1 pro videdwith suitably spacednotches 19X adapted to receive one end of a spring or linger 20 preferably secured to the' stem 21. The stem 21l is provided with a hand wheel 24, whereby sa1d stem 21 ma be readily rotated.

The operation o the valve 1s as follows Assuming thevalve as seen in Figs. 1 and 2` to be connected to a radiator and with opening 3, as the inlet, secured toa steam supply pipe in the usual manner, it is evident that which cio-acts with the screw cap 10whereby a tight jointl is formed between said ber to a radiator or the like in the usual.

face 18- which coperates with 4the ground face 5 in the casing 1 and is normally main-- is provided. with a ground face 5 adapted to when a solid portion of the valve body 16 is presented to the perforations 2X in the casing 1, as seen in Fig.A 8, no steam can pass from the inlet 3 to the interior of the valve disk 16 and consequently is cut' oli? from the radi'- lator to which said valve is connected. `When it is desired to admit steam into a 'radiator the hand wheel 24 is rotated suiiiciently to cause the spring or finger 2O to move in the direction indicated by the arrow in Fig. 5, whereupon said finger leaves one notch 19X in which it vwas held and enters another 19, correspondingto the changed position of the parts. The turning of the hand wheel 24 causes the stem 21 and consequently the valve 16 to turn in unison therewith.v

When the finger 20 is in the position seen in-F ig. 5 the valve is closed and no steam can enter the radiator with which it is connected. When the valve' body 16 is turned in the directionindicated byl the arrow in Fig. 8, the finger. 20 moves in unison therewith so that when the finger 20 is turned from its normal position seen in Fig. 5 and brought to the point a, one erforation 17 in. the valve body 16 is broug t in alinement with a perforation 2"` in the casing 1 and sulicient steam is admitted to the radiator to heatone part therein., When the linger 20 is brought to thepoint b two perforations 17 are brought into alinement with the perforations' 2X and sufficient steam is admitted to the radiator to heat two parts therein. When the linger 20 is brought to the points c, d, etc. three, four, etc. perforations 17 are brought into alinementwith the perforations 2X andsucient steam is admitted into the radiator to heat three, four, etc. columns therein so that when all the perforations 2X in the casing l are in1 alinement with perforations 17 in the valve body 16, the valve is open to its full extent and all the columns in the radiator are heated, it being understood'that when the finger 20 enters a notch 19 it locks the valve body 16 against rotation unless carried beyond said notch by the operator continuing to turn the hand wheel 24 until it reaches the desired position. In practice the perforations 2 in the casing 1 are the same in numbers as the number of columns in a radiator.

It will be observed on referring to Fig. 3, that the construction of .the valve seen therein is substantially the same as that seen in Fig. 2 with the exception that the inlet and outlet for the steam in one of said valves are transposed as` regards their positions the othervalve.

It will now be ppare'nt that I have devised a novel and useful construction which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description and while I havein the present instance shown anddescribed the preferred lembodiment thereof' which has been found in practice to give satunderstood that the same is susceptible of modication in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described myinvention, what I claim as new and desire to secure by Letters Patent, is

In a valve, a casing having an inlet and an outlet, a partition in said inlet having a plurality of ports therein, a valve mounted Within said casing and having a plurality of ports adapted to co-act with the ports in said partition, said valve having a ground joint connection with said casing, a cap secured to said casing and adapted to adjustably engage said valve, an actuating handle for said valve, and means for locking said valve in an outlet, said inlet being provided lwith a plurality of ports therethrough, a cupshaped valve mounted within said casing and having portsin the side thereof adapted to co-act with said inlet ports, a portion of said valve having a ground joint connection with.`
