April 25, 1932) J. J. LAWLER AUTOMATIC THERMOSTATIC RADIATOR VALVE Filed sepht. 21. 1951 Patented Apr. 25, 1933 Y UNITED STATES i a'1-|;1w ,OFFI'-CE i I asians J. LAwLER, or! MMNON, YORK l l @l Applieation filed september 21, 1931. serial 10.564,121. e:

thermostatie radiator valve constructed for the manual and thermostatic control ofthe flow of heating medium therethrough, 4the valve comprisinga casing 5 having a side?- outletnipple 6 to which a connector 7 is at- '55 tached by the nut `8, the connector 7 being adapted for attachment to a radiator or other heating element. The lower' open end of the valve casing 5 has a litting 9 engaged there-5,- with as by a threaded connection and the "60 fitting 9 is adapted'to beplaced into communication with the source of supply of a heating medium. A transverse web 10 is arranged interiorly of the valve lcasing 5 and forms an integral part'of the wall structure 65 This invention relates to certain new and useful improvements in automatic thermostatic radiator valves. Y

Thesprimary object of the invention is to 5 provide an automatic thermostatic radiator valve wherein a valve casing contains a valve seat with a manually operable valve engageable with one side thereof and a thermostatically operated valve engageable with the other 10 side of the valve casing, may be controlled either manually or thermostatically. Y Y

A further object of the invention is to provide a radiator valve of the vforegoing' character wherein a ring or annulus forming a part of the valve casing and constructed to contain an expansible fluid, has an expansible tube in communication therewith and directly engaged with the thermostatically operative valve to effect automatic operation of said go valve in controlling the opening and closing movements thereof, the expansible fluid being rendered more sensitive by the provision of a tubular cross arm extending between opposite sides of the ring or annulus and located in the valve casing in the path of iow of the heating medium.

With the above and other objects in view that will become apparent as the nature of 3 the invention is better understood, the same consists of the novel construction, combination and arrangements of parts to be hereinafter more fully described and then claimed.

in the accompanying drawing, forming a part of the application and to which reference parts throughout the several 40 view of an automatic thermostatic radiator valve constructed 1n accordance with the present invention, and showing the manual and thermostatically operated valves separately engageable with opposite sides of a. valve seat, and

Figure 2 is a cross sectional view taken on lines 2-2 of Figure 1, showing the thermostatic ring or annulus and the tubular connecting web traversing the valve casing.

Referring more in detail to the accompanying drawing, there is illustrated an automatic is had by like characters designating correthereof vand is disposed below, the outlet 6a through the nipple 6, the web having a centraiI opening therein defining a valve passage with an opposit'ely extending annular flange-.-y surrounding the opening in the web yto provide upperand lower, valve seats 1l andf12 respectively.

The valve seat 11 is adapted to be engaged byV a manually operated valve 4for shutting'Af oii1 the flow of the heating medium through 75 the valve casing, this valve comprising a valve stem 13 threaded through a bushing 14 `mounted in the upper end of the valve casing 5 and operated by the handle 15. "The lower,

end of thelvalve stem 13 has a swivel connec- 80 tion 16 with a valve 17 that is constructed as illustrated with afre'movable and renewable disc member or Y'washer tov compensate for wear.

annulus 18 castintegral with the fitting 9V and surrounding the same, a tubular cross 90 web 19 extending bet-Ween opposite sides of ring or annulusas illustratedV with the intermediateportion of thetubular web traversy ing the fitting 9l to be disposed in the path of/ kflow of the heat-ing medium so that expansible fluidwithin theannulus and web is rendered more sensitive to varying heat` conditions. Thering or annulus is charged with/expansibleluid by means of tubularnipples thatua(l are closed by screw plugs 20.

The thermostatically operated valve thatV open end soldered, welded or otherwise secured to the walls of the web opening to place the eXpansible tube in communication with the web and annulus. A cylindrical. plug core 22 is disposed within the eXpansible tube 21 with the upper end thereof anchored to the closed upper end fof the expansible tube, while the lower end of the plug core extends downwardly through the opening in the.

upper wall of the web 19, the plug core moving in wiping contact with the wall of the lweb opening, the core having a longitudinally extending facial' groove 23 to permit the Viiow of expansible luid from' the annuhis n and web into the eXpansible tube 21. A valve 24 is carried by the upper end ofthe eXpansible tube 21 and is adapted to be moved into engagement with the valve seat 12, and to eliminate vibration of. the valve 24Vand to insure proper operation` of the'therinostatic i devices associated therewith, .there is provided a coil spring 25 interposed between the Vvalves 17 and 24. i

From the above detailed description of the device, it is believedv that the construction and operation thereof would at once be'apparent, vit being noted that the flow of heating medium through the valve casing may be shut off when desired bythe manually operated valve 17 that is engageable with the valve seat 11. 'I he automaticy closing oi the valve is accomplished by the thermostat-ically operated valve 24 that moves into engagement with the seat.12, the atmosphere or air surrounding the radiator valve lowing in l 'Contact with all surfaces/of the ring or annulus 18 while theheating medium flows in Contact with the web 19 to render the operation of the thermostatic devices more sensitive. The eXpansible fluid .causing eXpansion andcontractionof the expansible tube 21 and coriespondingmovement of the valve 24: toward and away from itsl seat 12.

A I/Vhile there is herein shown and described the preferred embodiment of the invention, it is to be understood that minor changes may be made therein,

in the scope of the invention as claimed;

What I claim as new is: y f j 1. In an automatic thermostatic radiator valve, valve casing,a doublevalve seat therein, and manual and tlierinostatically operatsuch as will fall with- Y `extending between sides of the annulus and transversing the valve casing in the path of flow of the heating medium.

3. In an automatic thermostatic radiator valve, valve casing, a double valve seat therein, and manual and thermostatically operated valves respectively engaged with the valveV seats, thetherinostatic valve comprising anexpansible iiuid containing annulus formed integral/with the valve casing and surrounding the casing, and an expansible tube in communication with the annulus and carrying vrthe thermostatically operated e valve` and aftubulaijweb extending between sides of the annulus'and transversing them valve 'casing in the path of flow of the heating medium. 1 p

"In testimony whereof I affix my signature.
