STEAM-RADIATOR.

Specification of Letters Eatent. Patented A111. 19, 1910- Application filed June 27, 1908. Serial No. 440,611.

To all whom it may concern:

Be it ,known that I, \V LBUR M. WHIT- LOCK, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain Improvements in Steam-Radiators, of which the following is a specification.

The objects of this invention are to provide an improved device which may be attached to a radiator to vent such portions thereof as desired; to thus enable the occupant of a room to regulate the heating of the room; to avoid opening and closing the steam valve, and to secure a uniform regulation; to provide a simple and durable construction, which can be applied to radiators now in use without requiring any modification thereof, and to obtain other advanta es and results as may be brought out in the following description.

Referring to the accompanying drawings, in which like numerals of reference indicate the same parts in the several figures, Figure 1 is aside elevation of a radiator embodying my improved regulating means; F ig. 2 is a horizontal section taken on line 22, Fig.1, looking downward; Fig. 3 is a central vertical longitudinal section of the lower part of the radiator; Fig. 4 is an inner end .view of a certain plug upon which the different parts ofiny invention are mounted; .Fig. 5

is a central vertical longitudinal section of the said plug and parts carried thereby; Figs. 6 and 7 are central sectional views of the plug taken on line 6-7, Fig. 4, looking in the directions indicated by the single and double arrows, respectively, and Fig. 8 is a side view of a certain valve from its under side.

In said drawings, 10 indicates an ordinary steam radiator made up of

sections

11, 11 fastened together by means of rods as is common, and provided with the usual feed pipe 12 and valve 13-throu'gh which the steam is supplied. At the bottom of each section, apertures are formed in the, op 0- site sides with bosses 14 adapted to fit snugly together, and form steam tight joints whenthe radiator sections are clamped together; the apertures of each section register with those in the adjacent sections and thus a longitudinal chamber 15' is formed.

The end section 11 farthest from the steam inlet valve 13 is provided with a plug 16 screwed therein, said plug being usually in radiators as heretofore used a solid closure,

and nothing more. In my invention, however, the plug 16 is chambered centrally and longitudinally as at 17, to form the seat for a tapered plug valve 18, held seatedby a washer 19 and nut 20 of usual construction at the inner end of the lug 16, and adapted to be turned by a hand e 21 upon a stem 22 which projects outward through a stufiing box 23 at the outer end of the plug 16. At the upper edge of the outerend of the plug 16 is mounted a vent valve 24 of any ordinary and well-known construction in automatic valves of that type, the said vent valve 24 communicating by the pipe 25 which supports it and by

passa cs

26, 27 and chamber 28 with the plug va ve chamber 17. At the lower part of the plug 16 are

longitudinal recesses

29, 30 and 31 extending from the inner end of the plug toward its outer end but terminating short thereof so as to be closed at their outer ends with respect to the plug. One or more of these recesses may be employed in a plug as desired, and from them tubes extend longitudinally through the chamber 15 of the radiator to such different points thereof as desired. For purposes of illustration, I have shown in the drawings three

recesses

29, 30 and 31, from one of which as 29 a tube 33 extends about two thirds the length of the radiator, from another as 30 a tube 34 extends about onethird the length of the radiator, and from the other 31 there is no tube but said recess opens directly into the radiator. The said

recesses

29, 30 and 31 all communicate at their otherwise. closed ends with the plug valve chamber 17, as by

ducts

35, 36 and 37, respectively. The plug valve 18 has a 1on gitudinal groove '38 which near one end is adapted to register with one of said ducts 3:3, 36 or 37, and at its other end opens into an annular groove 39 which always registers with the passage 27 at the top of the valve and which leads to the vent valve 24. Obviously, therefore, according as the plug valve 18 is turned to bring its longitudinal groove 38 into registration with one or another of the

ducts

35, 36 and 37, the radia tor will be vented from one or another of the inner ends of the

tubes

33, 34 and recess 31. That is, if the lever 21 stands centrally verticah the vent valve 24 will be in communication through my improved plug 16 with the vent tube 34, so that the radiator will be vented for about two-thirds of its length next the steam inlet. The air in the rest of the radiator will be trapped, and accordingly that portion of the radiator will remain cold. By swinging the lever 21 in one direction, the radiator will be vented through tube 33 and consequently even less, or about one-third, of the radiator will be come heated, or by swinging it in the other direction the radiator will vent through recess 31 and its entire capacity will be available for heating purposes.

It will be noted that I do not affect the steam valve 13 nor the vent valve 24, but simply change the passage through which air escapes from the radiator to said vent valve. In this way I enable the effective heatin area of the radiator to be varied as desired and very simply.

If desired, limits for the lateral swinging for the handle 21 may be provided by forming a groove i0 transversely of the plug valve 18, and which groove receives the end of a pin 41 projecting from the body of the plug 16 and adapted to engage the end walls of the groove simultaneously with the registration of the

end ducts

36 and 37 with the longitudinal groove 38 of the valve. The middle position of the valve can be determined by the vertical position of its handle 21. In the construction shown in the drawings, an annular bushing 42 surrounds the stem 22 of the valve 18 at the outer end of the chamber 17 to close said end of said chamber around the valve stem 22 and provide a bottom for the stutling box 23.

It will be understood that the particular construction of the plug 16, or of the controlling valve therein, shown, is not essential to my invention, and may be modified to suit varying conditions; the number of venting branches within the radiator may also be varied, so long as the radiator is vented from a plurality of oints by inclosed tubes which are contro led b valve means. My improved device may urther more obviously be employed for venting in different systems of heating, whether sin le pipe systems using an automatic air va ve as shown, two pipe systems having a vacuum chamber or the like, or still other systems.

Having thus described the invention, what I claim as new is:
