HEAT-CONTROLLING- DEVICE' FOR RADIATORS.

Specication of Letters Patent.

Patented May '7, 1912.

Application filed July 7, 1910. Serial No. 570,878.

To all whom t may concern:

Be it known that I, THOMAS K. LYsINGEn, of VVilkinsburg, Allegheny county, Pennsylvania, have invented a. new and useful Heat-Controlling Device for Radiators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 .is a view, largely diagrammatic, illustrat-ing the application and use of my invention; Fig. 2 is a face view of the valve device; Fig. 3 is a section on the irregular line lll-TH of Fig. 2 looking in the direction of the arrow; and Figs. 4 and 5 are detail sectional views taken on the line TVMV of Fig. 2 showing the valve in different positions.

My invention has relation to heat-controlling means for radiators, and relates more particularly to that class of devices in which the radiators are provided with fluid pressure valves, such as air valves, and which are controlled from a more or less distant point such as a convenient place on the wall of thc room or apartment in which the radiators are located. Various automatic devices for this purpose have been proposed, operating by thermostatic action, and some of these have gone into extended use. A great deal of difficulty has been experienced, however, by reason of the fact that these devices constantly get out of order and fail to work properly, and there are more or less constant complaints from the tenants of large buildings in which such devices are installed. Practical experience with such devices has shown that the ordinary tenant is not particularly desirous of a controlling device which shall regulate the temperature automatically to any desired degree, but is desirous of a simple and convenient device, capable of manual manipulation by which he can easily and readily turn the heat on and 0H from the radiators from a convenient point on the wall.

My invention is designed to provide such a device.

lt also furnishes a simple ,and inexpensive device which is adapted to take the place of the thermostatic devices now used, being capable of attachment to the same wall plug as those devices and without disturbing the pipe connections which furnish the pressure for opening the radiator valves.

Referring to the accompanying drawings,

t-he numeral 2 designates a steam radiator having a steam admission pipe 3 provided with a control valve 4. This valve is of the well known type which is held open by the action of a spring and is closed by means of air pressure admitted from a suitable source. 5 designates an air supply pipe leading to this valve through a wall plug 6 also having a pipe connect-ion 7 with a suitable source of compressed air such as indicated at 8. The wall plug 6 which I have herein shown is the ordinary plug which is now in use with the well known form of thermostatic regulator, and the pipes 5 and 7 are the usual pipes which are connected to this plug.

The connection between the pipes 5 and 7 is effected by the usual port or passa-ge 9 in the wall plug, which is provided with the usual cut-oft' valve 10, which enables the valve 4 to be opened in case the usual thermostatic valve does not operate. This valve 10 may or may not be employed in connection with my invention, and prefer ably would not be where my invention is installed independently of existing systems. l/Vhere, however, it is used to replace existn ing systems, this valve may be retained to avoid expense in changing the wall plug.

In accordance with my invention, l place a suitable washer 11 on the outer face of the wall plug 6, this washer having therethrough ports 12 and 13 for communication with the pipes 5 and 7. I also secure to the wall plug, as by the screws 14, a valveseating plug 15 having therein a valve 16 with a spindle 17 projecting through a suitable packing 17a and retarding nut 18. The outer end portion of the valve stem or spindle 17 is provided with a combined pointer and handle 19 arranged to move between the stops 20. When this handle and pointer is in contact with one of the stops the valve plug 16 is in position as shown in Fig. 4 to connect the pipes 5 and 7 and admit air to the valve 4; whereas, when the pointer is in the through position, the port leading to the pipe 7 is cut oif and the pipe 5 is connected with a suitable exhaust. 16a is a washer against which the inner end of the valve 16 seats. For this purpose the valve plug 15 is provided with a port 21 which communicates with the pipe 5 through the opening 12 in the washer, and also with a port 22 which communicates with the pipe 7 through the opening 13 in the washer. The valve plug is provided with a port- 23, which, in the position shown in Fig. 4:, connects the two ports 21 and 22. This valve is also provided with an exhaust port or passage 24E,y which in its other position connects with the port 22 to provide an exhaust outwardly through the stem of the valve.

My invention forms an exceedingly cheap,

disturbing existing connections or requiring any cutting into or defacement of the walls of the building. The valve mechanism is shown as inclosed in a suitable casing 25, which may be of any desired neat or ornamental appearance.

lll hat I claim is l. The combination with a radiator having a connection for supplying` it with a heated heating fluid, a valve for controlling the supply of such iiuid, and a motor for actuating the valve, of a wall plug located in the wall of the apartment in which the radiator is placed, a pipe connection leading from said plug to the radiator valve motor and also from said plug to a source of pressure supply, an attachment secured to the plug and having ports therein which communicate with the said pipe connections, and a hand valve mounted in said attachment and controlling said ports, substantially as described.

2. The combination with a radiator having a fluid pressure valve, a motor therefor, of a wall plug located at a distance from said valve, a pipe connection leading from the wall plug to the radiator valve motor, a

ter with the passage in the casing leadinY f D from the tirst pipe connection when the valve is moved in another position, and a valve stem connected to said valve extending through the casing; substantially as (lescribed.

3. rEhe combination with a radiator having a Huid pressure valve, a mot-or therefor, of a wall plug located at a distance from said valve, a pipe connection leading from the wall plug to the radiator valve motor, a second pipe connection leading from the plug to a source of pressure supply, a casing connected to said wall plug having a plurality of ports communicating with said pipes, a rotary valve mounted in said casing, said valve having a passage arranged to register with said ports to connect the two pipes when the valve is in one position, there being a second passage open to the atmosphere in said valve arranged to register with the passage in the casing leading from the iirst pipe connection when the valve is moved in another position, a valve stem connected to said valve extending through the casing, and a combined pointer and handle connected to said valve stem; substantially as described.

In testimony whereof, I have hereunto set my hand.
