specification of Letters Patent. Patented Feb, 27, 1917,

Application mea April 25, 1914. serial No. 834,512.

To all 'whom z't may concern:

Be it known that I, CHARLES; J. DUDLEY, a citizen of the United States, residing at North Tonawanda, in the county of iagara and State of New York, have invented certain new and useful Improvements 1n appended Valves, of which the following is a. specification, reference being had therein to the accompanying drawing.

'This invention relates to valve structures and appertains to that class thereof which are utilized in connection with steam radiators.

The primary object of the invention is to provide a valve of the kind specified wherein the co-acting parts are so aggrouped and related that the quantity of the passing fluid, etc., may be accurately predetermined.

It is a further object of my invention to provide an eflicient form of valve that is simple in design and construction and in which Athe essential instrumentalities provided are so aggrouped that certain of these are replaceable for purposes which will hereinafter be set forth.

The invention in genera-l seeks to provide a valve structure which, as already specified, is particularly adapted for use in connection with steam radiators and which structure from an operative standpoint, will in practical use possess a high degree of eiiiciency and durability.

Other objects and advantages will in part be obvious from the annexed drawings and will also be in part pointed out in the following description.

The invention resides broadly in the features of construction, combinations of elements, and arrangements of parts, andvin various aggroupments thereof, all as will be exemplified in the construction hereinafter set forth, and the scope of application of which will be indicated in the claims hereto appended.

In order that this invention may be clearly comprehended by those skilled in the art, drawings illustrative of one of the many possible embodiments of the same are hereto as a part of this specification; it being manifest that othervpossible embodiments employing the underlying principles of my invention fall within the spirit thereof and within the objects contemplated thereby.

In these drawings:

Figure l is a view in vertical section of a valve-structure embodying my" invention, the. parts being in such position that the valve is closed;

Fig. 2 1s a fragmentary view, vin vertical section, showing the valve open;

Fig. 3 is a view in horizontal section, on the line 3 3, Fig. 2, the split-ring being shown, in this instance, as having been turned somewhat to bring its ends into view, similarly as in Fig. 2;

Fig. 4 is a fragmentary view in elevation looking into one of the openings in the valve-body;

Fig. 5 is a collective view of the insert member, in elevation and in vertical and horizontal section, respectively; and

Fig. 6 is a similar view of the split member-retaining ring.

Referring to the drawings, the referencecharacter l designates a casing which obviously may be of any preferred form and construction, provided that it includes an inlet port 2 and an outlet port 3. In this instance, the outlet port is formed in the tubular portion 4 arranged at an angle to the casing, and which is in communication, through said outlet port 3 and an opening 20, with a chamber', on the interior of the casing.

Upon the outside of said casing, at its upper portion, there is provided a circumferential enlargement or flange 6 which may be graduated or otherwise marked, for a purpose presently to be explained. This casing` etc., constitutes one component of the valve structure.

The casing is, preferably and as shown,

a valve stem 12 which is provided with screw threads 13 adapted to engage the inner threads 9 in the sleeve 8. The stem, at its lower end, carries a head or enlargement 14 provided with an annular recess 15. --The head and the stem on which it is formed-v constitute one'of the active means for controlling the passage of steam or the like through the outlet and, according to itsparticular position therein, operates to close said port entirely, or to open it to varying degrees.

The, stem is rotated manually, and this operation is facilitated by the hand-piece 16, which is preferably detachably secured to the upper end of the stem, as shown.

Also secured to the stem, in any preferred manner, is a pendent' collar 17, the lower portion of which occupies an annular recess 18 formed between .the upper end of the sleeve 8 and the casing. Mounted upon this collar is an indicator extension 19 adapted to overlie the graduated iange 6, as shown in Fig. 1, and to coperate with graduations thereon (not shown) to indicate to the operator the relative position ofthe fluid-controlling instrumentalities.`

As shown in Figs. 1, 2 and 3, the portion 4 of thecasing isprovided with an opening 20 of a vertical dimension less than the vertical dimension o-f the stem-carried head 14. Seated in this opening is a reducer element l or flow-determining member 21 comprising *a disk portion 22 and two rearwardly-eX-I ltending portions 23, between vwhich there is formed, in the disk, an opening 24 which, in:` this instance, is shown as rectangular, though it may be of any other desired or required form. The disk portion of the element occupies an operative position in a recess 25 formed in the vertical wall of the portion 4. The rearwardly=extending por- I l tions 23 project through .the opening 20 and beyond the exterior plane of the head 14. To this end,the portions 23 are cut on an arc so thatthe curved edges thereof' embrace the periphery of the head 14. Any suitable means may be provided for retaining the reducer element 21 in operative positio'n. In this instance, I have shown, as an example of such means, a resilient member 26, in the form of a split-ring. The ringis adapted to be sprung into a'groove 27 vformed in the portion 4 of the casing. When the head 14 is in its lowermost position, it abuts against a flange 28 formed in the casing'and, when in this position, said head entirely closes thev opening 24, as shown in Fig. 1. -When the stem is manipulated to elevate the head away from the flange 28, it will, in progressive degrees, permit a flow of Huid between the portions 23 and through the opening 24 of the reducer element and out through the outlet port 3. The preferred uppermost position of the head is illustrated may be a series of these reducer elements provided with differently-sized openings to accord to predetermined calculations, whereby a predetermined'quantity of steam may pass therethrough. In other words, their size bears a definite ratio to the normal pressure of the steam and the volume and size of the radiator to be supplied; that is to say, if the size be, say, 60 sq. ft., the opening 24 will be cut so that no more steam, under a iveounce pressure, (say) can pass through the valve and into the radiator than will fill, for instance, a sixty-foot radiator up to 85% of its capacity or volume. Thus, it will be seen,no steam can be wasted, since less than the maximum capacity of the radiator is provided and, in this way, over-heating of the radiator and waste of steam are avoided.

From the foregoing it will be perceived that I have succeeded in devising a valvestructure which is well adapted to achieve the several objects and ends in view. The structure is compact in form, is characterized by simplicity, and the parts are so formed and constructed as to permit of its ready application.

As many changes may be made in the construction herein disclosed and many widely different embodiments of the invention can be made without departing from the spirit thereof, it is intended that all matter contained in the foregoing description and shown in the accompanying drawings shall be interpreted as illustrative and not in any limiting sense.

It is also to be understood that the language used in the following claims is intended to cover all of the generic and speciic features of the invention which, as a matter of language, might be said to fall therebetween.
