HEATING sYsTniu.

To all whom .'i't-mayiconcem:

`Be it known that I, EGBERT H. GOLD, a

the United States,`

Chicago, in the county of Cook and State of .Illinois,haveinvented certain new and useful Improvements in Heating Systems, of

- which the following is aspecication.

My inventionvrelat'es to. heating systems particularlyadapted for heatingv railway cars, and `has for its object lto provide a heating system employing several radiating coils or radiators which may be controlled by a. single automatic controller, if lsuch controller be used, which coils are provided with switching` devices, lwhereby certain of the coils may-be put into service singly, when desired, o r in conjunction with other coils,

one or more of these other `coils being of a strictly vsecondary or supplemental character, that is, receiving steam` only when the .firstinentioned orprimary coils are in service.

While the arrangement of radiators, valves and controlling devices which forms the subject-matter of this application might be employed'invarious heating systems' of diifer` ent description, this arrangement isparticulai-ly' designed and intendedfor an atmospheric. pressure or vapor system of heating and, more especially,;' for a vapor system when used to heata sleeping car or the like, and in this regard it is one of the objects of my invention to adapt and modify the wellknownivapor system of car heating to meet certain requirements of sleeping cars.

In my application Serial No. 500,477, filed June 7, 1909, I have shown two coils, a main coil and a supplemental coil, controlled by a single Vautomatic controlling device and provided with valves whereby steam may be circulated through the main coil or through themaincoil and thesupplemental coil in succession; and in my application Serial No.

500,478, filed June 7, 1909, I have shown and claimed a parallel arrangement of coils,

Aalso controlled by a single controller, in

which the several coils are capable of being supplied with steam independently, but

which coils may be so connected as to receive the `steam serially in combination with certain other devices and arranged so as to provide a suitable system for heating apartment cars. The present invention com bines the arrangements of the two aforementioned applications, thereby providing'an ,arrangement ofthree coils, all of which may be conresiding at same principles.

.trolled by a single automatic controller, two of Whichcan be used independently of4 each other and of the third, the third being a sec-v ondary ior supplemental coil which is fed from and dischar es linto one of the rstmentioned coils. bviously, the coils might be multiplied to any desired extent upon the The arrangement is preferably such that the steam, of necessity, flows in series through such of the coils as are danger of short open coi s. v

The invention is illustrated as applied to heatingl a sleeping car divided into a main seating section and a compartment, for eX ample, the womens lavatory; and it is one of the objects of my invention to provide a heating system which shall adequately meet the exigencies of this and similar situations. The invention might, how.-

eVer, be employed in other connections.

The invention has for further objects such other new and improved constructions, devices and arrangements in heating systems as will be described in this specification and particularly set forth in the claims appended hereto.

The invention in the preferred embodiment is. illustrated in the accompanying drawings, wherein- Figure l 'is a fragmentary, sectional plan construction,

however, diagrammatic for the purpose of clearness of illustration. Fig. 2 is a sectional.. plan view through the three related four-Way valves and their connecting pipes. Fig. 3 is a section taken on line 3-3 of Fig. 2, looking in the form of vapor regulator suitable for use in this connection.- l

vLike characters of reference indicate like parts in the severalfigures of the drawings.

Referring to thedrawings, reference letter A designates a sleepin@ car of ordinary construction divided into tlie seating section Band a. compartment C, the latter forming the Womens lavatory.

Reference letter a designates the seats. D is the train pipe, which runs the length of the train and is kept filled with steam from the locomotive at 'relatively high but variable pressures.

direction of the arrows;. 'and Fig. et is a vertical, sectional view of a y preferably provide a main radiating coil E, which runs thelength of the car, through' the seating portion B and also t-he lavatory C, beingarranged adjacent to the water pipes and the like, so as to keep the latter from freezing. This coil is shown in horizontal position in F ig.l 1, in order that all of the devices constituting the heating f system may be clearly shown in a single lorview. In practice, these pipes will be ara ranged in the customary place along the ysides of the car. The radiator E is calcu- Ylated toafford suiiicient radiating surface to -keep the'car' orthe lside of the car on' which it is located heated to a normal temperature in moderate weather and to impart suicient heat toprevent the water pipes in the car from `freezing up in any weather.

' This radiator is intended to be kept in service 20 all the time, day and night, in winter time, While thefcar is in service. For supplying additional heat to the seating section of the car, incase of cold weather, and particularly in the day time, I provide a supplemental 25,l coil Fwhich is so connected withthe main coll E that itreceives steam only when the' main coil is in service. For heating' the womens lavatory, I provide an additional.

coil G, which is so'connected with the other f coils that it may be put under steam in conjunction with the main coils E, F or independently of the same. n

H re resents the vapor regulator, by

means of which steam is'maintained at sub` stantiallyatmospheric pressure in such of the coils as may be in service; and J, J J 2' fpur-way valves interposed between the radiators and the controller in the manner which will be hereafter described. v

A suitable form of vapor regulator is shownin-Fig. 4, although any other device might be employed for controlling the inflow to the radiating pipes in accordance r with thermostatic conditions adjacent their v ...45 common outlet. A casing 10 is divided by a partition-11, so as to form a' high' pressure chamber 12j and a low pressure chamber 13, these chambers being in communication by means of a port 14 closed by a valve 15 arranged on a stem 16, which is pivoted to a bell crank 17. Arranged in a thermostat chamber 18 is a thermostat 19 upon which.'

- rests a rod 20, pivoted to the other end 'of V bell crank 17 Figs. 2 and 3 show the construction and arrangement of the four-way valves. These valves are identical in construction, so that A but one needs to be described. A casing 21 is divided by webs 22, 23, 24, 25 into com` *50 partments, 26, 27, 28 and 29. Between the webs is arranged a valve-piece consisting of the upper disk 30 and the lower disk 31, connected lby a vertical web 32. These parts 'are arranged on a stem 33 provided with a 'handle 34, a spring 3'5 being interposed be- J and -26 of J2.

.womens lavatory tween the bonnet 36 and the upper disk 30. The lower disk is perforated at 37, which perforation registers with a perforation 38 in the bottom of the casing when the web 32 "isin the dotted line position of Fig. 2.

- A short pipe section 39 connects the train `pipewith the high pressure chamber 12.

T he low pressure-chamber 13 is connected by pipe 40 with compartment 26 of valve J. Compartments 27 of valve J and 26 of valve J are connected by a pipe 41. A pipe 42 leads from .compartment 27 of J to the thermostat chamber 18 of thermostat H. A short pip'e43 connects compartments 28 of 4 kThe inlet and return ends 44 and 45'of` coil Gr lead respectively from and to compartments 29 and 28 of valve J.

The inlet and return ends 46 and 47 'of coil E lead vrespectively from and to compartments 29 of J and 27 of J2. Theinlet and return ends 48 and 49 of coil F lead respectiyely from and to compartments 28 and' 29 o J2.

The operation of the heating system when constructed as above described is as follows: Coil E will be kept filled with steam at atmospheric pressure whenever the car is inservice and requires heat. In moderate weather this coil will 'suffice to heat the car even in the day time. During' the sleeping hours, itwill be used alone, even in quite cold weather. It isa source of complaint that, as sleeping cars are now heated, the temperature is too high during the night and particularly during the iirst hours of the night. vThis results from that fact thatv there is no way of putting out of service a part of the heating coils. I obviate this ob?, jection by dividing the radiator into subdivisions which'c'an be used' separately or and 27 of valve J, compartment 26 of valve J to coil E and from coil E through compartments 27 and26 of valve J2, compartments 28 and 27 of valve J and-thence through pipe 42 to the thermostat chamber 18 of the controller. Valves J and J 2,will be set in the position shown by the dotted lines In cold weather,

inv Fig. 2, short circuitin coils Gr and F. By

shifting the position o the valve-piece of J2, the steam, after passing through coil E, Will be forced to pass through coil F before it can reach the thermostat chamber. Coil gemaa- G may be cut into the circuit by shifting the valve-piece'ot valve J to the positionv shown ofthe radiators as may be in service;l The'- jsteam vo long astliesame is4 open, and then goes Ward reaches the thermostat chamber 18 by ineans'of the common discharge pipe 42 leading from valve J.: The Contact of thev steam With the thermostat expands, the same,-

causing port 14 to be either closed entirely or throttled. As ya result, only so 'much so arranged as to protect the water pipes,

sie

steam passes'valve l5 as will suiHce for keeping the radiating coils in service' fullof steam at substantially atmospheric pressure. It will benoted that the supplemental radiator F, that is the supplemental coil which' runs, through' the berth section of the car, can not by any possible manipulation be used alone, therefore it is impossible 'for ail-ignorant or careless porter. to heat-the berth section of the car without employing the main or long coil Eivhich is preferably drips, basins, etc., which Would be likely to become frozenup'A in very cold Weather. On the other hand, the supplemental coil Gr can be'used independently of the main coil E, this being necessary when, for example,

,the supplemental coil. G is employed for heatinga Womans lavatory which may requir heat very early in themo'rning even .When no heat is needed in the berth section.

I do notlimit'inyself to the particular deyices, constructions and arrangements shown and described, as inodiiications might be devised Which would come Within'the scope of iny invention as defined by the claims. p

Following the customary practice, the heating described for oneside of a car will ordinaril e duplicated on the other side I dol ot claim specically in this specification'fithe parallel arrangement of the four- Way valves J, J and their respective coils G and E, nor do I claim specifically the serial arrangement 'of the .valves J J2 and their respective coils E and F, as similar arrangements are shown and claimed in my co-pending application, Serial No. 500,477,
