Specification of Letters Patent.

Patented "a. I7,1918.

Application filed April 6, 1918. Serial No. 227.079.

Yo 1 17/ who; if may r'rmm'rn lie it known that l. EDWARD J. KILEY, a eitizen of the luited States. residing at ('hieago, in the eonnty ot' (ook and State of Illinois. have invented eertain new and useful lmprovements in Valves, of which the following is a speeitieation.

This invention relates to valves. and more partieularly to -valves adapted for use in eonueetion with radiators l'or variably eontrolling the volume of fluid to be. delivered at a predeterluined openin g ot' the valve. and has partieu lar referem-o to the types of valves eommouly known a. graduated" and packless valves.

()ne objeet of this invention i to produee. a valve of. the eharaeter referred to eomprising improved means for etleetively sealing: the valie stem in all positions of the valve.

Another objeet of my invention is to provide a graduated valve embodying improved means for variably eontrolling the amount of tiuid delivered through the vaive and an indieating ring provided with improved means for adjustably interlocking the same with the easing.

A further objeet of the invention is to produee an improved valve whieh will be simple. eompaet and durable in eonstruetion. and el't'eetive and ellieient in operation.

To the attainment of the ends and the aeeomplishrnent of other -new and useful objects as will appear, the invention eon- -sists in the features of novelty in the eonstruetion, eombination and arrangement of the several parts hereinafter more fully de scribed and elanued and shown HI the aeeoman in" drawin s illustratin the embodiment of the invention, and inwhieh Figure 1 is a eentral vertieal sectional View of a valve embodying the prineiples of my invention.

Fig. 2 is a detail seet'ional view taken on the line 2- 2 of Fig. 1. Fig. 3 is a perspective view of a" slotted Washer which is employed in the eoustruetion disclosed.

Fig. {is a sectional view taken on the line 4-4 of Fig. 1.

Similar referent-e eharaeters denote eorresponding parts in the. various views.

6 valve herein diselosed eomprises a body 1, provide with an inlet and outlet 2 and 3. respeetiu-ly. wh-ieh may he threaded as shown for eonneetion with a radiator 01 the like. The upper end 4. of the body is apertured and internally threaded for the reeeption ot' the externally threaded sleeve 5, of the bonnet (i. whieh is provided with a shoulder 7, adapted to seat against the end suri'aee ot' the body to prevent leakage. For the purpose of eoutrolling or governing the amount of fluid to be delivered through the. deviee. a valve member 8. having a threaded eonneetion with the valve stem 9, is provided. 'l'hevalve member 3 is pieferahlv eonstrueted as shownand is mounted for longitudinal movement relatively to the stem. but. interloeked against rotation relalively to the body 1 by means of projections It) provided on the inner surfaee of the sleeve and grooves riphery ot' the upper portion of the valve member H. whieh is slidably mounted in the openinglr! of the sleeve 5. The lower portion 8' of the valve member substantially eonoidal adaptedtori'iiiperate withthe port 13 formed in a web in the easing to variably eontrol the amount of lluid delivered through the deviee. the greatest diameter of the portion 8' being substantiallv the same as the diameter of the port. l isposed below and in'alinement with the port 13 is a second port 14 formed in a web in the easing, whieh is of smaller dimensions than the lirst mentioned port and is provided with a flaring seat 15. adapted to be engaged by I portion 8 adjaeeut its small end to prevent passage of fluid through the d-eviee. lt will thatby rotation of the stem 9 in one direction the valve member 9 map he moved into engagement with the seat 15 to (lose the valve to prevent passage of fluid therethrough as shown in Fig. 1. and that by rotation of the stem in the opposite direction the valve member will move out of engagement with. the seat '15, thereby opening the valve to' permit fluid to be delivered therethrough. The amount of fluid delivered through the, deviee is governed by the lift or the amount of movement imparted to said valve member, the eonodial portion 8' thereof cooperating with the port l L-to vary the etleetive opening of said port in a manner as -will be readily understood. it will be obvious from the foregoing that one size of valve eon- 8 is shown as 'strueted as herein deseribed and illustrated 11. formed in the pe' in shape. and isbe obvious in the drawings may be employed to properly control the fluid supply to radiators irrespective of their size and capacity.

The valve stem 9 is rotatably mounted in a suitable aperture formed in the bonnet (i, and is provided with a flange 16 having an annular arcuate bearing surface adapted to seat against the inner surface of the flanged cone shape sealing member 17, which is mounted in a counterbore of similar conformation formed in the bonnet, The sealing member is referably composed of metal having softer c iaracteristies than the flange 16; such for instance as lead, tin, zinc, coper, etc., or a metallic alloy thereof, and may e secured into the counterbore by compression or by a peening operation to secure a joint that will be proof a ainst leakage. While I have shown the mem er 17 as being secured in the valve casing, it will be obvious that it may be mounted on the valve stem if desired, and adapted to cooperate with a bearing surface provided in the casing. Positioned within the cavity 18 formed in the bonnet 6, and surrounding the stem 9, is a compression spring 19, .which exerts a pres-- sure against the U shape washer 20 which is removably mounted in an annular groove 21, formed in the stem 9. This spring constantly urges the valve stem 9 in an upward direction and tends to yieldingly maintain the flange 16 in contactual engagement with the sealing member 17, thereby effecting a perfect seal between the two, as readily will be understood. Adjustablymounted upon the shoulder 22, formed on the exterii r surface of the bonnet 6, is an indicating ring 23 upon which in turn rests a retaining disk 24. The indicating ring 23% formed with a serrated opening adapted to the casing so as to engage the angular portioirgthereot to adjustably retain said ring in any desirable osition, as shown in Fig. {and has'a stop ug 23 preferably formed" integral therewith, for a purpose to be described crcin after. The bonnet 6 is al'soprovide with a reduced extension or ncckQ-"r which projects through a suitableaperture provided in the retaining disk 24 and is adaptcdto be received within the opening 26 of thecap 27, which is mounted upon said retaining disk. The cap 27 is provided with'a handle 28, and has a polygonal opening adapted to slidably receive the end 30, of the stem which is of similar conformation, WllPlObY a rotation of the cap will impart movement to said stem. A screw 31, engaging the end of the stem and having its head disposed in a counterbore formed in the top of the cap may be employed for securing the latter in position, and a lock washer 32, may be provided for preventing the screw from work} ing loose. The end 30 of the stem is shown as mounted in the cap in a nmnncr to permit axial movement of the stem 5), relatively.

to said cap as the parts beer me worn by use when in service. This arrangement eliminates the possibility of breaking the seal around the stem and consequent leakage as the result of downward pressure on the operating handle or on the end of the device, which is an objectionable feature common to devices of this character. Formed inte gral .with the cap on one side thereof is an indicator 33, which is adapted to engage and cooperate with the lug 23 to determine the full open position of the valve, while other positions of the valve may be represented by marks, as shown or otherwise.

The cap 27 may be provided with a cover 34, which can be readily removed when it is desired to readjust the screw'31 to coin pensate for ,wear of theparts.

Having fully described my invention and shown one form embodying the same, I do not wish to be limited to the details of the construction shown, since these can be obviously changed without departing from the spirit and scope of the invention.
