TEMPERATURE-REGULATING APPARATUS.

No. 816,046. Specification of Application filed June 6,1

To a witmn it may concern:

Be it known that I, Jenn A. Bennett, of Bayonne, county of Hudson, and State of New Jersey, have invented an Improvement in Tom erature- Regulating Apparatus, of which the following is a specification It is the object of my invention to auto matically control the flow of a temperature changing mediumsuch as steam, hot water, or arefrigerating agcntby the movement of a door or windowsash, by which the air, of which the temperature has been changed, is allowed to escape from the apartment. The

temperature-changing medium is to prevent waste b shutting oil the temperature-changing rne iurn when the user of the apparatus prefers to open doors, windows, or outletsto allow the heated or cooled air to escape in stead of closin off the sup ly of the steam or tern reratureeliangin me( ium. 7 H

ll y invention may e applied as well to the control of a refrigerating medium asto iejf; heating medium; but its most interestingsp plication is to steeni-hcatin systems, and therefore I have illustrated this application of it in the drawings.

In steam-heating systems the amount ng heat transmitted by radiation is in proportion to the difierence in the temperatures of the steam and the external air in contact with the radiator, and consequently when a door or window is opened not only is the heat of the escaping warm air lost, but the admission of cold air to contact with the radiator produces more rapid condensation and conseuent waste of heat, since at such time a re motion and not an increase of heat transmission is desired. under such cases the waste may be ver great, as the amount of heat transmitted t rough a radiating-surface exposed to a strong draft of air at exterior temperatures may exceed three times the transmission under the normal temperature 7 that should be retained in the apartment. For the regulation of heating systems the; invention is applicable as well to indirect as to direct systems. i

In carrying out my invention I employ an Letters Patent.

heat transmission the temperature of the apartment under the control of a suitable valve, and this valve is controlled automatically at will by the movement of a door, window-sash, or the like whenever the same is opened to allow the heated or refri ereted 'air to escape from the apartment an the exte: rior air to enter. In the preferred construction the controlling-valve for the torn eraturc-chsnging medium is operated by a uidressuremotor, which is In turn controlled the sash or door controlled devices. Many methods are known for controlling motor-valves, and I do not mean to limit my in vention to any one of such known methods, as the invention comprehends, broadly, the automatic control at will by the opening of at door, window, or other outlet of the supply, discharge, or circulation of the temperaturechanging medium.

*"steelfneating in which the air end water of fifzondensation are drawn into the returns by a. pertinl'vscuum or lower pressure maintained therein this partial vacuum or lower pressure may be economically utilized as the mo- .tive force for operating the motor connected with the supply-valve. This action of this suction on the motor me be controlled by the sash or door controlle devices in various ways. it may be conveniently controlled b a sash or door controlled valve in the brane suction-pipefroni the return to the motor,

In applying my invention to a system of acting to open communication to the motor or to open a vent and relieve the suction, and I have shown this application of my inven- "tion in the drawings, 7

It is also an ob ect of my invention to en-i able the controlling-valve of the tempersture-chan ing medium to be operated from sny' one o a series of windows or doors and whcii the invention is so applied to a vacuuni system of steam-heating to revent by auxiliary valve devices the loss 0 suction or artial vacuum in the return when the vent m the branch suction-pipe to the motor is open, 7

It is also an object of my invention to eninclosed space, such as a radiator. or'refrigcrating cell, through which the te'mperatpge changing medium passes-be it steam,

able the 00IliiI'0ll1i1-V&lVB of the temperature-changing me inm to be operate b liisnd at will to close said valve indepen so iofthe operation of the sash or door con- Wetsr, or a refrigerating fluid-to cliensebv litre s1 devices.

In the drawings, Figure l is a side elevation of a steam-radiator and one form of my controlling devices arranged to be operated from either of two windows. Fig 2 is an enlarged view of part of the same with one of the motor-controlling valves and the heatcontrollin valve and its motor in vertical section. *ig. 3 is a side elevation of a radiator with the controlling devices arranged to be operated from a single window, the motor-controlling valve and the hcat-control ling valve and its motor being in vertical section; and Fig. 4 is a view similar to Fig. 3, showing the air outlet controlled devices combined with an auxiliary temperatureregulating device controlled by the temperature of the apartment.

a is the radiating apparatus in which the heating medium is to be controlled. As shown, it is an ordinary steam-radiator having its inlet connected with the supply-pipe b and its outlet with the return-pipe c, in which a lower pressure or partial vacuum is created by suitable exhausting a )paratus. The return-outlet is controlled by a suitable automatic valve d.

e e are the windows or doors by which the apparatus is to be controlled.

f is the supply-valve, which, as shown, is connected with a fluid-pressure motor g, which is operated by the partial vacuum in the return 0 under the control of valve de vices controlled by the doors or windowsash.

h h Ii. 72.3 represent a branch pipe leading from the return 0 to the motor-chamber of the motor g, and interposed in this branch pipe are the sash or door controlled valves. These valves are intended to open or close the pessage through the suction-pipe to the motor and may be of any convenient form. As shown, they are constructed as followszi is a suitable casing forming the valve-body interposed in the pipe h h h h When the motor is to be controlled by any one of a series of window-sashes or doors, as in Fi 2, there is a controlling-valve for each, an they are connected up with the sections of the pipe h h h h in series. In Fig. 1 I have shown a controllingvalve for both the 11 per and lower sashes of each window. P rom the valve-bodyi there is an outlet to the atmosphere which is controlled by a valve k, normally closed on its seat by a spring is. On the valve 7c there is an extension m, adapted to be struck by a movable piece or lever n, arranged to be operated by the window-sash or door, so that when the latter is opened the valve In will be pressed back off its seat, opening the outlet j and breaking the partial vacuum in the motor. When the windows and doors are closed, all of theoutlets :1 will be closed, and a partial vacuum will exist in the return 0 and through the pipe h h h k to the motor, and the supply-valve f will be opened by atmos heric ressure on the m0- tor-dia hragm. en, owever, any of the contro ing doors or windows is opened, it will operate the lover or art n to open the corresponding valve 10 and relieve the vacuum in the motor and permit the supply-valve to close.

My invention is not limited to any particular form of motor device for operating the supply-valve but the form shown in Fig. 2 is especiall adapted for the purpose. 0 is a motor-diap1ra m which is connected with the valve-stem y a connecting-frame and is depressed by a spring q to close the valve f. I prefer to use the connecting-frame p for the purpose of enabling the valve f to be closed at will inde endently of the o eration of the motor. For this purpose I ave shown an eccentric r, having its spindle ournaled in the motor-casing an acting in the frame p to depress it and close the valve f. The eccentric acts in an enlarged opening p of the frame, so that while it is effective for closing the valve f it cannot be used to open it, as the movement in the op osite direction will produce no motion in tie frame or valve, which can therefore be opened only by the motor.

The opening of any one of the valves 7: would, unless means are employed to prevent it, result in a loss of partial vacuum in the return-pipe c, which in an extensive system might be serious. To prevent this, I inter- .pose the valve s in the branch suction-pipe.

This valve acts to restrict the passage-way through the branch suction-pipe when any of the controlling-valves 7c is opened. It operates with the supply-valve f. In the construction shown t is a valve-casing having two sides divided by a web and communicating, respectively, with the section it and section 71/ of the branch suction-pipe. In th s web is a small port controlled by the valve .9, the latter being normally closed toward its seat by a spring t, but without ever entirely closing the port. A projection t on the frame acts on the stem of the valve s and fully opens the valve when the frame p 1s elevated'i. 6., when the supply-valve f is open. It resultsthat when steam IS turned on and all of the controlling-valves lc are closed the valve 8 will be fully open; but when the subply-valve f is closed and the frame 1) 1s lowered the valve 8 will close down to restrictthe passa e through the branch suctlonlpe, and t us prevent the partial vacuum one being destroyed. It Wlll be noted that this partlal closure of the valve 8 will remain until the valve f7' has again opened and the pro jection t li ts the valve. Therefore after the valves k have closed the exhaustion of air from the motor-chamber will be radual an there will be a slow opening of .t e supply-- alve, while the closing action Wlll be quick,

In Fig. 3 I have shown the apparatus apwith said valve and means automatically .plied to a single window or door. In this case the restricting-valve s is not necessary, as the sash or door controlled valve k may be operated to close the branch k to the return when the branch h to the motor is opened to the atmosphere. In this construction the valve k is of the piston type, projecting throu h the valve-casing 1c and carrying a roller 3 on its end, which engages a notch in the sash the valve beingbprojeoted by a spring la. The branch pipe frornthe return c opens into a valve-chambegfroni which the pipe It leads to the motor. i5 is a port to the atmglslphere controlled by the'pis ton-valve 7c. 1811 the window is closed and the piston-valve is projected, the port In is closed and the pipes in and it are in communication with the motor; but when the .window'is opened the piston-"valve is pushed back and closes the port to the pipe It, wh le opening the port k to the pipe h and permit- --ting the partial vacuum in the motor to be relieved. In Fig. 3 I have shown a simple fluid-pressure motor having a diaphragm 0 connected with the stem of the supply-valve and depressed by a spring g.

It is desirable in many cases dow-controlled devices should be combined with a controlling device controlled by the temperature of the apartment, and such an arrangement is shown in Fig. 4, in which it is a vent-pipe from the pipe h to the motor, having its vent 7L controlled by a thermostat it. When the temperature of the apartment does not exceed normal, the vent h is closed; but when the torn erature rises above,

normal the expansion 0 the thermostat it will open the vent and break the suction in the motor and close the valve even When the windowcontrolled valve is not operated. Any suitable form of auxiliary temperaturecontrolling device controlled by the temperature of the apartment may be used in lieu of that shown and may be operatively connected with the motor in any convenient manner.

While I have shown the motor operated by suction, it is apparent that it may be operated by compressed air or any other motor fluid.
