Patented Aug. 1, 1939 UNITI-:1o- STATES .2,168,072 vAL-v-EJHANDLE, WHEEL, AND| THE. LIKE "incent` P. Rumely, Chicago, Ill., assigner to Crane Go., Chicago, Ill., a corporation of Il- .linois Application October 27, 1937, Serial No. 171,227

` 401mm. (c1. Vifi-117) My invention relates to improved means for providing the'combination of 'a conventional type of valve handle in assembly with a valve stem featuring simple and effective ventilation at .its

5 central or hub portion thereby overcoming the objectional effects ofthe heat transfer normally loccurring in service lbetween the wheel and stem. The latter condition obviously contributes to an undesirable condition in the manipulation of the wheel or handle.

I am aware thatin `the past means for ventilating valve handles and 'the like have been provided, `but to my knowledge these prior constructions have either necessitated expensive and` frequently impractical Hprovisions, such as special rim openings involving special complicated cores, or else the hub of the handle or Wheel has necessarily been made sufliciently large to accommodate a special circulating or Yheat dispellingcham- 20 ber. However, these types Vof earlier constructions have introduced troublesome jproblems in the foundry or else in :the `machine shop objectionable expense has been 'incurred thus making the cost of the improvementprohibitive, especially realizing the staple .character of' the article involved. In addition, the past efforts in this direction have frequently'necessitate'd the addition Vof extra parts applied to the `Wheel and stem Vassembly, thus Yadding furtherto the cost thereof. It will be evident that my invention is capable of very broad application in numerous `unrelated elds, but in my experience 'I have been mainly concerned with its application to Vsuch metal valve wheels and handles where heating of the Wheel has 'been a real problem. YExamples of the general types of wheels and handles in contemplation are disclosed on' page 166 of Crane Co.s No. 52 Catalogue, andare designated, respective-- ly, as styles C, D, E, F, M, N and U, as well as 40 the lever type of handles therein referred to,

respectively as styles J, K and S. E

Special steps have been taken at various times in the past to design the hubs, spokes or rims of the wheels and handles presumably in an effort to reduce the amount of heat transfer occurring, but so far as I am aware none of these steps has included the provisions for the constructionv which is hereinafter described in detail.

As a principal object of my present invention, simple and effective means are provided for removing the heated air from around the stem and also such accumulations thereof which normally are above the stem and around the wheel nut, thus avoiding the entrapment or pocketing of the heated air and facilitating the local circulation of the generally cooler air-of the surrounding atmosphere.

, It will be further apparent that by the same means which are used for effecting such desirable air circulation the valve wheel or handleis also -5 rendered capable of being adjustably positioned in anumber of different degrees of angularity with relation to theV vertical axis of the valve when the latter is closed, so that a more nearly perfect axial alignment with the valve body can 10 easily besecured.' For example, in connectionV with an oval wheel or a lever handle vit may be desirable that the major or longitudinal axis thereof extend'parallel, or substantially so, with the horizontal centerline of the valve, and the -15 latter positioning can be accomplished easily by simply lifting the wheel or handle from thestem vand then repositioning it as desired.

"Further, bymy invention I avoid expensive machining because I am able to use a preferably in- 20 tegral air passage construction in which the necessary circulation grooves being of relatively simple form, are easily made in the foundry core or upon the pattern itself.

Other objects and advantages will become more 525 readily apparent upon proceeding with the speciiication in connection with the accompanying drawing, in which Fig. 1 is an exterior plan view of the top of a preferred valve handwheel incorporating one em- :30 bodiment employing the principle of my invention.

Fig. 2 is a longitudinal sectional View taken on the line 2-2 of Fig. l, showing a fragmentary assembly with a conventional valve stem A. Y -35 Fig. 3 is a transverse sectional view taken on the line 3-3 of Fig. 1.

Fig. 4 is a section taken on the line 4-4 of Fig. 2 showing the connection between the valve stem A and the wheel. 40

Similar reference characters refer to similar parts throughout the various views.

As illustrated in the plan View of Fig. 1, a conventional type of oval valve handwheel is generally designated as I, having a central hub portion 45 generally designated as 2, with the internal polygonal configuration 3, the sides of which, as shown more clearly in Fig. 4, allow for fitting the hub 2 snugly upon a preferably tapered valve square 4, the latter contacting with the cored 50 configuration 3 intimately upon the four sides thereof except for the relieved channels 5 preferably spaced equidistant upon the sides ofthe square'3. As shown in Fig. 2, the grooves 5 extend vertically and are preferably parallel, or substan- 55 tially so, in relation to the axis of the valve stem A.

'Ihus the relieved grooved portions 5 as well as the corners of the core square 3, as shown more clearly in Fig. 1, are perimetrically arranged so as to accommodate the square of the stem as desired, and it is further apparent that the cored square 3 with its relieved portions 5 on any axis passing through is a symmetrical gure. Therefore, regardless of the degree of angular rotation which the handwheel may assume when the valve is closed, the wheel may be adjustably positioned as desired and there will remain an idle number.

of relieved portions around the square having for their function the carrying away of diffusion of the heat normally accumulating therebetween as transferred from the usually hot valve stem.

However, it is obvious that if the usual valve handle or wheel is attached to the stem A in the conventional manner, employing for examplethe threaded spindle 8 and the nut 9, the Ventilating passages 5 might thereby easily be covered or plugged and thus the complete circulation therethrough would be prevented. Accordingly, to overcome such objection I provide that the upper face portion of the wheel hub 2 is made with relieved horizontally positioned radially extending channels 6, the ends 'l of which extend beyond the periphery of the handwheel nut 9. Therefore, as shown in Figs. 2 and 3, each of the vertical passages 5 will connect at its upper limits with the horizontally extending grooves or passages 6 and thus provide for complete circulation of the heated air between stem and wheel to escape into the surrounding atmosphere.

Thus by simple relieved means which are provided integrally within the cored hub portion of the handle or wheel, a substantial heat dspelling circulation of air is obtained without the sacrifice of any of the essential contacting surface necessary in operating the wheel and the stem, in addition to eliminating separate pieces as heretofore provided and without the need for employing complex foundry practices.

It should be obvious that the size and the shape of the handwheel or the handle and its central cored portion may vary considerably, depending` upon the installatio-n, without affecting the application of my invention. Further, the detailed manner in which the circulatory passages or channels have been provided may also be varied considerably. I desire, therefore, to be limited only by the extent of the claims appended hereto. I claim: l 1. A handle adapted to engage a stem, the said handle having an integral apertured hub for nonrotatable engagement with the said stem, means for holding the said handle to said stem, intercommunicating through passages arranged in transverse planes respectively within the said aperture and upon the upper surface of the said hub surrounding the engaged portion of the said stem whereby circulation of air therepast within and adjacent to the exterior of the said hub and immediately beneath the said holding means is provided.
