SLEEPING-CAR HEATER.

Specification of Letters Patent.

Application led November 23, 1908. Serial No. 464,957.

`To all whom it may concern:

Be it known that l, Eonnirr H. GoLD, ,a citizen of the United States, residing at Clliicago, in the county of Cook and State f Il inois, have invented certain new and useful Improvements in Sleeping-Car Heaters, of which the following is a specification.

My'invention relates to a steamheating system yd't-isigned and intended particularly for the heating; of railway cars; and the invention has for its object to provide certain new and useful devices, arrangements and constructions relating to heating systems which will be hereinafter more fully' described.

One of the primary objects of the invention is to provide the radiating coil or other radiator with means for checking or preventing` the gradual drip of water of condensation through the controlling means, after the supply of steam to the radiator has been shut oil", thereby lesscning the danger of the freezingr'up of the fluid passage ways and valves of the controlling' means when the latter is located in an exposed position,

is the case with the controller in the ordinary types of steam heating` systems employed on railway cars.

lhc invention is illustrated incertain preferred embodiments in the accompanying drawings, wherein Figi-ure 1 is a son'iewhat diagrammatic view illustrating the circulating' coil of a car heating system and the controlling device thereofv` the former being col'istructcd in" accordance with my invention. Fig. 2 is a similar vien' illnstrath'ngr a modification; and Fig. 3 is a sectional view of the forni of controller shownin the preceding lig'lires.

Like characters of reference indicate like parts in the several iigfures of the drawings.

ltcferringi iirst to Fig. 1, A represents,-

diag'rannnatically the radiating coil of a car heating' system. which may he placed in any desired location within the car, the floor line of the latter being indicated in the drawings. B is the stean'x train pipe which runs the length of the train and is supplied vwith steam from the locomotive or other source of supply. 7) is a. supply pipe which leads from the train pipe l to the controller The construction of the controller K4 This device consists of a casing 10,. divided by a web 11 into a. high pressure Chamber 12, and a low likely to injuri` it. advantages of the ordinary steam heating pressure chamber 13 which communicate by a port'lll, closed by a valve 15, the stem of which` 16 is connected with a bell crank 17, pivoted to web 18 which supports thc casing 10. Steam enters the chamber. 12 from the train pipe B throngl'i pipe Z1, passes through the usual strainer20, and when valve stands open, enters the low pressure chamber 13, passing from there through pipe 21 to radiator A. From the radiator A the steam or water of condensation Hows through a pipe 22 into the thermostat chamber 23, formed by a casing 24 attached toweb 18. rlhis chambercontains the thermostat 25 provided with the rod 2G which to the bell crank 17. The the top of thermostat 25 so that when radiator A is filled with 4st'eai'n and the steam forced ont into the thermostat chamber, thcri'nostat 25 expands and moves the Valve 15 againstv or toward its seat, thus closing or throttling port 14. With the shutting ,otl of steam from the radiator, condensation takes place in thc discharge end ofthe radi "ator and as thermostat25cools, ro'd 26 sinks and opens valve 1.5,adm1tt1ng a further sup# ply of steam to the radiator. The exposed position of the Vt-hermostatic controller K beneath the car makes it liablclto be frozen 11p in extremely cold. weather, and partielllarly if the supply of steam be shut oil from the radiator A. After steam is shut off from the radiator there will be a gradual.,l 'coohnpof the pipes anda ,gradual condensation of the steam therein, followed, in the ordinary steam heating systems, by a slow dripping' of the water of condensation in small amounts througlr the col'itrollingf dc- \-ice, which is located ordinarily at a lower level that the pipes', which dripping' sometimes continues several hours, the water becoming' colder and colder as tin'ie goes on. rThe danni-.iol' thel con))aratively narrow passage nays in thc controller becoming,r frozenl is very cx'insidcrahlc in severe weather Patented Mar. 21, 1911.

is pivoted rod 26,1'ests upon and with the controller so clogged with ice it'. is obvious that when itis desired to heat the car again ay great deal of time and trouble may hecxpcnrlcd in thawingy outorotherwisc clearing the outlet to the system. lvloreovcr. thc frecyaingi'ip of the somewhat delicate mechanism of the' thermostat is To obviate t'l'iese dissystcn'is. l provide `one or both ends of my radiator. with means for trappmg a certain preferably of a loop which lies in a plane at an angle to the horizontal, which loop may be formedi'n and be a part ot the supply or return pipe leading from the controller to the radiator or from the radiator to the controller, as the case may be. In the arrangement shown in Fig. 1, the. pipe 21 is formed I with a loop 54 which stands above the level of the end of the radiator into which `it opens, and the pipe 22 is formed with a corresponding loop 55. With this arrangement the flow of steam to the radiator and the flow of water of condensation therefrom is not checked during the ordinary operation of the system, although, of course, a son'lewhat higher degree of steam pressure is'required because of the resistance which the loop offers to the outflow of the water of condensation. When, however, steam is shut oif from thefradiator, the loops 54 and 55 will trap a portion, at least, of the water of condensation, and obviously, the portion which is last tocondense and is coldest, and retain the same within the radiator, which being located within the fcar is not subjected "to the low temperature to which the'controller underneath the car is exposed. The danger of the thermostat becoming frozen is therefore veryv considerably decreased. When the steam is turned-on again the accumulated water of condensation in the radiator is blown out and thereafter the system operates in the ordinary manner.

In Fig. 2, I have shown a'somewhat modified form of system in-which but one loop or trapping devlce is required. In this case the radiator C' is supplied through the controller by a pi e 56 which leads to a art of the radiator a ove that from which t e discharge pipe 58 leads back to the controller. In this case the drip through the valve chambers of the thermostat is very inconsiderable so that ample protection is afforded by the single loop 57 in the pipe 58.

I havevillustrated my invention as applied to the protection of the controlling device of a heating `system in which the infiow of st eam is controlled by a thermostatic devlce located so as to be affected by the thermostatic condition of the medium at the outlet of thesystem. It is obvious, however, that the device of my invention might be employed in other situations where it is desirable to 4protect a controlling device or fluid conduit from the liability to become frozen up by a gradual dripping of water of condensation when such controlling device or conduit is located in an exposed position, and the radiator or .similar device with which it is connected is located in a more protected situation; or generally speaking, when-it is desirable, for any reason, to prevent a gradual drippin from the radiator or like device through t e part to he protected, vthrough the controller, or conduit, and to permit the outiiow ot' water of condensation only when there is a certain minimum of pressure above atmospheric pressure in the radiatoror the like.
