STEAM-HEATING SYSTEM.

Specification of Letters Patent.

Patented Jilin- 21, 1.913.

Application filed November 10, 1911. Serial No. 659,509.

To all nhom-z'zfmajij concern: I

Be 1t known that I, JOHN E. WARD, a

citizen of t'hedllnited States, and a resident of the borough of Manhattan of the city of New York; in the county and State of New York, have invented certain new and useful Improvements in Steam-Heatmg Systems,

' of which the following is a specification.

The invention relates particularly to apparatus for use in heating railway cars l u n where the steam is ordinarily supplied from the engine. ,In systems of this kind where a thermostatic device is used to control the supply of steam to the radiator circuit great difliculty is encountered due to the fact'that the condensed steam in the radiator pipes frequently spills into the thermostatic chamber in such mannerthat the hot watencan impinge directly upon the thermostatic member thereof.

The present invention is directed to a construction by which the. contact. of the hot water with the thermostatic controlling member is prevented.

As showing a specific embodiment of th invention reference is made to the drawings forming apart of this specification and in which- Figure 1 shows aside elevation of the car piping. This includes a pipe leading from the main or engine supply, the thermostatic controlling device, the pipes leading therefrom and returning thereto which connect to the radiator sections and a pipe connecting with the atmosphere which permits an escape of excess steam or the suction of air.

Fig. 2 is a side elevation partly in section 2. The steam coming from the pipe line 1' must pass by the valve 3 whose position is regulated by the thermostatic. U-shaped valve changing member 4. the regulating valve 3 the steam passes upward through the angle shaped pipe 5 hrough the nozzle 6 thence through the 1n-.

Wardly flaring portion 7 to the radiators ,8

After passing by means of the supply piping 9. of which the flaring portion 7 may be considered a part. It will be apparent that the steam passing through the nozzle 6 and through the restraining portion 7 will cause a decrease of press n'e'within the thermostatic device and any cooler steam returning from the radiator 8 through the pipe 10 will be sucked up by and mixed with the steam or higher. temperature which. passing from the nozzle 6 into the restraining portion 7. The waters of condensation. that flow from the radiating system through thepipe 10 'will pass under and entirely out of contact with the U shaped-thermostatic member 4 and'out of the overflow 11 which is directly connected to the atmosphere.

Sometimes the water of condensation will be spilled back from-theradiating system ner that all of'the water passing downward through the vertical opening 12 will fall beyond the U-shaped thermostatic member 4 and therefore not contact therewith.

'From an inspection of Fig. 2 it will be noted the valve 3 is provided with a stem 14 that is directly connected at 15 to the U- shaped member 1.. As this stem extends across and is located directly below the end of the vertical opening 12 the condensed waters flowing backward from the pipe 9 will necessarily'contact with said stem and unless there is provided some means for preventing said ivater from creeping along this rod or stem l i-it wouldv naturally follow along the same and from thence drip down upon the thermostatic member 4 thusv affecting said member and thereby the position of the valve which is undesirable. In order to prevent the water from creeping. along this rod in the manner above described there is provided a spring 16 whichv is retained directly under the opening on the rod.

From an inspection of Fig. 3 it will be observed that the thermostatic U-shaped memher 4 is located 23 sufiicient distance above the bottomof the interiorof the thermostatic device to permit any Water of. condensation which may bereturned to said device through the pipe to pass under said meni ber'wlthout actually contacting therewith.

It is obvious that various changes. and modifications may be made without depart ingfrom the spirit and scope of myinvenpipe, a nozzle for directing steam to said supply pipe and arranged relative to said passageway in such a manner as to produce a decrease of pressure within said device,

and thermostatic member being located below said passageway, the said chamber having therein and connected tothe casing thereof a shield between a terminal of said passageway and the thermostatic member, which shield is arranged to I prevent the water that passes through the passageway from contacting with said thermostatic member.

2. A heating system having a radiator line, a nozzle for directing steam to the radiator line, a casing having a chamber and a passageway which forms a communiv cation between the said chamber and the radiator line at 'a'place adjacent to the dc;

the nozzle terminatingl static member, and a s i absence liver end. or" the nozzle, 9. thermostatic mem er, in said chamber, the-end of Said passageway-which is farthest removed from i above the thermoold on the chamber casing and extending between said last 'mentiene' end of the passageway and the thermostatic member to prevent the splashing. of condensed 'water which passes through the passageway againstthe thermostatic member'. vl i 3.. In a thermostatic device for heating, the combination of a casing having a chamber, a U-shaped thermostatic member in said chamber, a rod which extends between the ends of said thermostatic member, said casing being provided with a passa eway lead- I ing to and from the interior 0 the chamber, the rod being located betweena terminal of the'passageway and the curvedpor: tion of the U-shaped thermostatic member, an apron or shield located'between said terminal and the curved portion of the thermostatic member, to prevent fwater entering the chamber through said opening, from engaging the thermostatic member, and means onthe rod to prevent:water that passes through said passageway into the chamber from creeping along the rod and thence to thethermostatic member. This specification signed .and witnessed f this 6th day of November A. D.,.1911. I JOHN E. WARD.
