Specification of Letters Patent.

To all whom it may concern:

Be it known that I, GEORGE E. I-IULsE, a.

citizen of the United States, residing at Newark, in the countyof Essex and State of New Jersey, have invented certain new and useful Improvements in Systems of Heating, of which the following is afull, clear,

' economical construction.

.and' exact description,. such as will enable others skilled in the art to which it appertains to make and use the same. I

This invention relates to heating systems and. more particularly to car heating systems.

One of the objects thereof is to provide an eificient heating system in whlch the temperature of an apartment is automatically maintained substantially constant.

Another object is'toprovide a device to be used in a system of this character which will be quick to respond to variations in temperature, and which will be positive in its action.

- I Another object is to providea device of this character which will be simple inoperation and which will be of durable and Other objects will be in part obvious and in'part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application'hf which will be indicated in the following claims.

' In the accompanying drawings, wherein is shown one f various possible embodi- 'ments of the invention, Figure 1 is a perspective View illustrating the relative positions of the various 'parts of the system;

. Fig. 2 is a vertical, sectional view taken through the automatic, regulator and the main valve; Fig. 3 is a side elevation of the valve; and Fig. 4 is an enlarged detail view of the piston in the inlet chamber.

In the drawings, in which similar reference numerals indicate similar parts throughout the several views, the system is shown as applied to a railway car, for which use it is peculiarly adapted.

A train pipe 1 which isin connection with a source of supply of a heated medium,

preferably steam from a locomotive, is connected by branch piping 2 to the radiators 3 located in the varlous cars, the said radi- Patented Feb. ,11, 1913. Application filed. April 10, 1909.-- Serial No, 489,224.

2 is avalve 5 located within a suitable casing 6 provided with inlet and outlet chambers 7 and 8'. The valve5'is provided with a stem 9 to which is secured a disk, or piston 10 so positioned as to divide the inlet chamher 7 into upper and lower portions'll and 12 and adapted to permit a leakage of fluid from said portion 12 to said portion 11- whereby the pressures in said portions are normally equalized, and the upper portion of the valve stem 9 preferably engages wi a socket 13 formed in the casing, whereby it is guided in its movements. The upper portion ll'of the chamber 7 communicates by a conduit 14 with the chamber 15 provided with;an opening lfi-co-mmnnicating with the outletchamber 8 of the valve casing 6, and. the flow of the heated medium through said opening 16 is" controlled by the auxiliary valve 17 which may be provided with a suitable spring 18 adapted to hold said "alve upon its seat.' The outer extremity of said auxiliary valve operatively engages a diaphragm 19 secured to the valve casing in any suitable manner. A spindle 20 mountedto reciprocate withinthe casing is positioned with one of its ends engaging said diaphragm 19 and its other'end engagmg a diaphragm 21 secured within the lower portion of the casing and forming therewith a chamber 22.v A spring 23 tends to raise said diaphragm and said spindle to unseat theauxiliary valve -17, the tension of said spring ,being greater than the tension of the spring 18. Aconduit 24 communicates at one end with the chamber 22 and, at its opposite end with the chamber 25 formed w1th1n the regulator casing 26 and separated from chamber 27 also, formed in said casing, by a flexible diaphragm 28, and said chambers 22 and 25 and the communicating conduit 24 are completely filled with a nonexpansive liquid-by means of which move-o ment of the diaphragm 28will be communicated tothe diaphragm 21. The chamber 27 contains a volatile liquid 28 such as chloroform the vapor of which completely fills the piping 29, the ends of which are closed and which, preferably extends substantially throughout the length of the car above the windows'thereof and is 'in communication with. said chamber as ,clearly shown in Fig. 1. The regulator casing is preferably mounted, upon the side wall of the car adjacent the piping 29.

The operation of the system, which should be largely obvious from the above description, isas follows: Supposing the temperature of the car to fall below a certain predetermined point, the pressure of the vapor within the piping 29 and chamber 27 will.

be decreased, permittin the diaphragm 28 to'move to the left in Fug. 2, and the spring 23 acting against diaphragm 21 will force the same upward, forcing the non-expansible liquid out ofthe chamber 22 and causing it to move upward in the piping 24 and simultaneously will cause the stem to move upward, thereby unseating the auxiliary valve 17. As soon as said valve is unseated the upper surface of said piston is thus relieved the pressure acting upon the lower surface of said piston will cause the valve 9 to move off of its seat, thus permitting the heated medium to flow to the radiators 3. If, now, the temperature rises above said predetermined point the pressure of the vapor in piping 29 and chamber 27 will increase; thus causing a reverse movementof the diaphragm 28 which in turn will force the nonexpanslble liquid downward through the ,pipe 24 into the chamber 22, causing the diaphragm-21 to bemoved against the tensionof the spring 23 and permitting the spring 18 to seat the auxiliary valve 17, which results in closing the outlet of the upper portion 11 of the inlet chamber 7 The pressure upon the upper surface of the piston 10 will then equal the pressure upon the lower surface thereof, and on account of the pressure acting upon the upper surface of said valve it will be seated, thus cutting ofi the supply of, the heated medium from the radiators.

Whlle the system has been shown as ap- "pliedto, and as peculiarly adapted to, a

railway car, it will, of course, be understood that it could be installed in any building or apartment wherein it is desired to maintain a constant temperature.

Asmany changes could be made in the above construction and many apparently widely different embodiments of this inven-' tion could be'made without departing fromthe scope thereof, it is intended that all matter contained in the above description or shown; inthe accompanying drawings shall be; interpretednas JIlustrati and not; im a limiting sense..
