' v l To all when?! it may concern:

Be it known that l, EUGENE S. MANNY, e subject of the King of Greet Britain7 residing in the city and district ol liv/lontresl, in the Province of Quebec, Ganado, have invented certain new and useful Improvements in Steam-Heating Systems; and l do hereby,

by means of e combination hot-wster and' steam system in which theweter is heated by steam derived from a boiler properly located. f

One of the greet objections to theuse oit systems wherein water is heated by steam in toll buildings is that owing 'to the extreme length of t ie supply-pipes leerling to the radiators and the return-pipes leading therefrom too greet e pressure is developed upon seid pipes, which renders it precticslly-irnpossible to use hot water Ator heating tell buildings.

The present system is designed for the purpose ot relieving this pressure upon the pipes and comprises two or more zones of radiators arranged in different levels7 erich :scheef rs-I dietors being supplied freine' water l essure tank common to ell ot the redietors in e pen ticulsr zone of radiators, but in nowef connected with the radiators in the next higher or lower-zone ot radiators, there being ineens provided whereby the Water lowing in each zone ot radiators nieybe heated, ond the sysl tem includes ineens for shutting oil the sopply or" steeni to any individual vertical series of radiators in eech zonefwhen 'the weiter in that particular series is heeted beyonrx.l e predetermined degree. Stettin is teken from boilers properly located end conducted into the couplings between the supply ond return pipes ot each vertical series ot vradiators for heating the water seperately in each of seid series of radiators, I l

T he invention consists in the combine-tion ond arrangement ot pei-ts which are shown. in the accompanying drawings, oli after more fully described, sind particularly pointed out in the claims, it being understood that said drawings illustrate the pren "tion, s, single which forms s,

hereini ferred construction, which moy departed from in the form, n end minor deteils of ps 5 of 'the cle ris w dreiwii'igs, in @renee ,ntieote the views, i is leef bnnri respon ding e sectional el lvstif equipped with `the p section being teken je f Woll v`of the buildin5;'.` partly eievs-tio in Fig; l, with th proper position Referring to the ellye stoein-e-'V 3 box with br which entend through which steam-p for heating the waiter l e i indicate radiators co series in the Lippe/rend building 5.

Leading to the coupling 9 is a steam-pipe 13, and thereon is a valve 15, which is adfpted to be actuated by movement of the phragm 16, which diaphragm is adjustably connected with the thermostat 17, which thermostat extends longitudinally of the ln the chamber 18 of the coupling is supported a tube 19, which is closed at its upper end, and extending into thel tube 19 is a steam-supply tube 2()v in connection with the steam-pipe 13,witli the valve 15 interposed between said members 13 and 20. In the operation of this coupling water will Y{iow in the direction indicated by the arrows in Eig. 2 from the radiators 4 through the short connection 4a to the pipe 8, thence through pipe 8 and the connection 8l to the As steam is admitted to the interioi of the tube 20 it will pass through the tube 19 and heat said tube 19, so that the water in the chambers 14 and 18 will be heated, the exhaust-steam discharging through the exhaust-pipe 21, which pipe leads to the pump 22, or otherwise, as may be desired.

1t is evident that when water is heated in the chamber 18 the water will likewise be heated in chamber 14, and owing to the re duced area of the opening 12 the water will chamber 14.

saidfseiies, and it is evident that one or more of said series from A to E may be cut oft entirely without interferingwith the operation As the main 23, leading from the tank 6,is connected to each of the series from A to E, inclusive, and wellknown means are provided for in aintaining a constant supply of water in said tank, it is evident that the necessary quantity ci Water will be supplied to the radiators of said series, and owing to the short length of' the supply and return. pipes 7 and 8 there will be rela-c tively littlepressure developed in said pipes.

The upper zone of the building is provided with series of radiators lettered, respectively,

be retarded in the chamber 14 to some extent, so that the passage thereof will be somewhat sluggish and will raise the temperature of the thermostat 17 according to the temperature oi the waterl in the chamber 14. When enough of the radiators 4 in any of the veitical series are eut oil", the temperature will be raised to such degree that the thermostat will aetuate the diaphragm 16 and through said. 2. diaphragm close the valve 15, thereby cutting F, G, H, l, and J, the series from F to J being substantially du licates of the lower series from A to`E, inc usive, and a second waterpressure tank 6u is provided in the upper zone of the building, which is connected by means ofthe main 23a with. the said series of radiators from F to J. The supply and return with couplings 9,as in the lower series, and the radiators 4 of said upper series are arranged in'vertical series, asshown and substantially as described. With reference to zone, so that the water is heated in the upper zone of the building from said steam-pipe 3, each zone having an independent water-pressuretank and independent live-steam conmay be operated independently of the other zone or Zones thereof and the pressure be kept down in all ofthe waterpipes of the system.

Having described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a heating system for heating water with steam, a supply-pipe, aradiator, areturn# pipe and a coupling for said pipes, said coup ling comprising an outer shell, with a partition approximately centrally of said shell but of less length so as to leave a water-passa re at each end thereof, a closed tube on one side of said partition, a steam-pipe extending nearly the length of and within saidtube, and a vthermostat on. the opposite side of said partition said thermostat being adapted to control the flow of steam through said steami ie.
