. STATES CHARLES MCDERMOTT, OF CHICAGO, ILLINOIS.

THERMOSTATIC RADIATOR CONTROL.

Application filed September 5, 1922. Serial No. 586,255.

Be it known that I, CHARLES C. MoDnn- MOTT, a citizen of the United States, resld ing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Thermostatic Radiator Controls, of which the following is a specification.

This invention relates to controls for heating radiators, and an object of the invention is to provide a window operated thermostatic control for automatically shutting ofl the passing of heating agent through a radiator when the window is open, and which will permit the passing of the heating agent through the radiator when the window is closed.

In hotels, oflice buildings, rooming houses and apartments, as well as dwellings, when the room becomes too hot the'occupant opens the window and when the window is opened for cooling off the room it places an extra burden. upon the heating system of the building causing practically the heating of the out doors and consequently requiring the use of a greater amount of fuel and the needless waste of heat, and it is an object of this invention to provide a structure for overcoming this needless waste of heat, by cutting oil the passage of the heating agent through the radiator when the window is open, and then when the room is sufliciently cooled the natural instinct of the occupant will cause him to close the window at which time the radiator valve will be reopened to permit the heating agent to pass through the radiator.

Another object of the invention is the provision of an arrangement of devices whereby the radiator may be cut oil from a source of heat automatically in the raising of a window.

Besides the above my invention is distinguished in the construction of a valve and pipe connection that may be used with the well known Johnson pneumatically controlled device for radiators so that when the window is raised or lowered, beyond a predetermined point, the radiator will be entirely cut ofi from the source of heat and besides, action of the thermostatic valve device and the radiator cut off valve rendered inoperative.

With these and other objects in view the invention will be better understood from the following detailed description taken in connection with the accompanying drawing wherein:

Fig. 1 is a diagrammatic view of the'complete system.

Fig. 2 is an enlarged view of the valve and its associate parts.

Fig. 3 is an enlarged sectional View of the control valve.

Figs. 4 and 5 are diagrammatic views illustrating the control valve in its two positions. Again referring to the drawing illustratmg one of the many constructions of my invention the letter B designates an ordinary radiator and the letter C window sashes that are raised and lowered in a well known manner.

The numeral 1 designates a pneumatically controlled cut oil" valve for a radiator which 1s now used in conjunction with the well known thermostatic valve device 2 wherein the thermostatic strip controls the opening and closing of a valve according to the temperature of the room. The numeral 3 designates my improved control valve comprising the casing 4 having the inlet 5 and outlets 6 and 7 and the port 8. The plug this provided with angularly disposed inner communicating passa es 10, 11, and 12 and further with the poc et 13. The outlet 6 is arranged in communication with the thermostatic valve device 2 by the main branch pipe 14 while the port 8 is connected by an auxiliary branch pipe 15 with the thermostatic valve device. A supply pipe 16 supplies air under pressure from any suitable source to inlet 5 while the pipe 17 establishes communication between the outlet 7 and the movable element of the cut off valve. For the purpose of operating the V valve in the movement of the window sash I provide the link mechanism 19 consisting of the valve handle 20 that is held in a pre determined position b the spring 21. The link 22 and the slotte cam arm 23 are pivoted to the window sash as indicated at 24. As the window sash C passes by the cam arm 23 spring 21 will throw the link mechanism into position illustrated in Fig. 2 with the plug 9 in the position illustrated in ures 3 and 4 so that air under pressure will pass directly to the cut oil valve for operating same in cutting off the steam supply to the radiator. When the window is lowered and the link mechanism operated the plug will assume the position illustrated in Fig.

' directly to the thermostatic valve device to allow same to function properly in the usual manner.

It will be noted pocket 13 plays an important part'in that when the plug is in position illustrated in Figs. 3 and 4 the air pressure passed directly to the control valve will not be allowed to; escape through the valve of the thermostatic device when the same is in position to exhaust air from the cut oil valve due to the lowering of the temperature.

As illustrated in Fig. 5 air is allowedto readily pass to and from the cut ofl' valve according to the operation of thethermd static device and thus it will be seen that with my improved invention the usual operation of the thermostatic system now in use is not interfered with when the window is not raised above a predetermined point. I

It is, of course, to be understood that the link may be positioned at any point along the frame so that the window may be opened any required distance before the radiator is llt is, of course, to be understood that the invention may be constructed in various other manners and the parts associated in diflerent relations and, therefore, I do not desire to be limited in any manner except as set forth the claims hereunto appended.

Having thus described my invention what I claim is:

1. In a room, the combination of a heat supply line, a ventilating device, a fluid pressure valve interposed in the heat supply line and adapted for governing the heat supply through said line, a fluid pressure line leading to said valve, thermal means controlling the fluid supply to said valve, and means for connecting the fluid pressure line directly with the valve in the heat supply line by rendering the ventilating device active and for connecting said fluid pressure line with the valve in the heat supply line by way of said thermal controlling means when the ventilating device is rendered inactive.

2. In a room, the combination of a radiator having a return, a window, a heat supply line for the radiator, a fluid pressure valve adapted for controlling the heat supply to' the radiator independently of said return, a controlling fluid line leading to said valve, thermal means controlling said line, and means for connecting said line directly with the valve controlling the heat supply line in opening the window and for connecting said controlling fluid line I with said thermal controlling means by closing the window.

3. In a room, the combination of a'radiw tor, a window, a heat supply line for the radiator, a fluid pressure valve interposed ling device to the window controlled valve, a controlling fluid line leading from'the window controlled valve to the fluid pres--- sure valve in the heat supply line, said window controlled valve having means for connecting the first controlling fluid line leading to the window controlled valve with the controlling fluid line leading from the window controlled valve to the thermal controlling device, and for simultaneously connecting the controlling fluid line leadin from the thermal controlling device to t e window controlled valve with the controlling'fluid line leading from the window controlled valve to the valve in the heat supply line when the window is closed, and for disconnecting the line leading to the window valve from the line leading to the thermal controlling device and the line leading from the thermal controlling device from the line leading from the window valve to the valve in the heat supply line, and simultaneously connecting the line leading to the win dow valve directly with the line leading from thewindow valve to the valve in the heat supply line when the window is opened.

4; In a room, the combination of a radiator, a window, a heat supply line for the radiator, a fluid pressure valve interposed in the heat supply line and controlling the heat supply to theradiator, a window controlled valve, a thermal controlling device, a. pair of said first pair of pipe lines with line 1 of the second pair of pipe lines and line 2 of the first pair of pipe lines with'line 2 of the second pair of pipe lines when the window is closed, and means for connecting line 1 of the first pair of pipe lines with line 2 of the second pair of pipe lines when the window is opened.

5. In a room, the combination of a radia-- tor, a window, a heat supply line for the radiator, a fluid pressure valve interposed in the heat supply line and controlling the heat supply to the radiator, a window controlled lit) from said valve, line 1 0 valve, a thermal controlling device, a pair of pipe lines leading to the window controlled valve a pair of ipe lines leading f said first pair of pipe lines constituting a controlling fluid supply line, and line 2 of said first pair of pipe lines leading from the thermal controlling device; line 1 of said second pair of pipe lines leading to the thermal controlling device, and line 2 of said second pair of pipe lines leading to the valve in the heat su ply line, the window centrolled' valve includlng a rotatable valve member having ports for connecting line 1 of the first pair of pipe ports for connecting line 1 of the first pair of pipe lines with line 2 of the second pair of pipe lines when the window is opened, and
