I STEAM-HEATING SYSTEM.

Application filed March 9, 1908. Serial No. 419,934.

-*To alluihom'it'my concern." Be 1t known that I, DANIEL BROADBELT, a

citizen "of the" United States, an .of New-York, borough of Broo a resident lyn, county Q'KingS, andl State of New York, have in- 'vented' certain new and useful Improvements the like.

in Steam-Heating Systems, of'Which the followingis a full, clear, and exact description.

l `.Tliisinvention relates more particularly to hea-ting Systems for houses, apartments and The primary object of'ithe invention .is to providef'siinple and eiicient -means whereby proper=.jcircl1latio n 'may be obtained in the ,heatingeomiections in' such a Way that the usual pounding of the pipes may be eectually overcome, and' to provide means Where- ;bysultableVV ventilation' may be secured "throughoutthe entire system or at parts thereof-lto'prevent' the: collection of air in.'

the .pipes4 Alfurther object'of the invention is to provide means whereby Vunnecessary pressure is aut()mz'iticallyv relieved',-and to prevent leak- -."agc-orf'other'injury to theconnectionsv by reason'v ofany excess of pressure.

these and other objectsin view the inventlonwill be `he'reinafter more particu- "larlydescribed with reference to the accom- .p afnylngg'"l drawings', which form a part of A-tlii's' specification, and-.Will then be pointed {cnt in 'the claires atthe-end ofthe descripf. thefdravvings, l?igure1 is a vertical Sb-tion h1-ugh a'building in which is ar-V f-ranga eone'formcf heating System embody" lng."illy'1l,irizen'tion'; and Fig. 2 is a vertical radiators 14.- Ther sectiknfshovving theboiler and the arrange- -1rfent ofone of the vent or stand-pipes- .40,

indicated at 25. *Aswvill be seen when' steam theboiler throughthe pipe 22 to the pipe 21 and through said pipe to the vertical steam pipes l5 and lG to any or all of the radiators, and in case of condensationl 'of the steam, the Water will return through the pipes and 1G to the return pipes 24 and into the boiler-again, though it will be understood that a separate return pipe from the radiators may be employedif desired.

To prevent air from collecting in the pipes or connections and to relieve said connectionsv of any excess of 'pressure so as to avoid pounding and togive proper cirtmlation to connect- With the return'pipes 2.4 on each side o'the boiler, and to each of said pipes 2G may be connected Aa: vent or stand pipe 27 in 'each of which is a valve 28, and vsaid stand is generated in 'theboiler it Willpass from 5 the steam, I provide pipes `2G"\`vhic h may y pipes may be of the same diameter and ex-V p tend urpivardly a suitable distance so as; to prevent the ordinary pressure in theboiler fromforcing the Water out yof said pipes, the upper endso which are open'and ma v be provided With a short L-shaped'pi'pe 29 with the open end extending.doivinvard so as to prevent dnstand the like from entering said pipe. The stand pipes 27 Yarc connected above the Water line to the return pipes 24 by means of a horizontally-extending vent pipe 30, andsaid pipe may be controlled between each of the stand'l and the return pipes by a valve 3l. There may be any desired number of stand pipes and one of said pipes may be at the rear .of theboiler and may bev provided with a valve 32. Q The pipe 30 is connected by short angular pipes'orconnections 33 to the return pipes 24 non each Vside ofthe boiler below the point Where the steam' l pipes join the return pipes, vand from the angular, connections 33 extend Yupward and downward vent pipes 34. These vent pipesl 34 are .each substantially- U-shaped inform, and are each provided with avalve 35, and

said pipes project upwardfar .enough to prevent the Water from being forcedout'of the vents 34 when the valves35 are opened,`

but will permit thel steam or air or any eX- cess pressure in the heating system to be relieved at these pointswithoutthe loss of the Water, as the angular 4connections ypro- A vide a direct connection 'for theiret-urnof:

anyl Water to the boiler. Byimeans. of the connections shown the entire system or any.y

part thereof may be relieved of any ,excess u sions are prevented andcertain partsof the system automatically relieved of any excess pressure in the pipes Vand the parts eectually lrelieveduof any air that might: collect' therein or 'otherwise cause pounding inthe-` i pipes, and that said systemis such that it Patent maybe applied -to the ordinary heating system with very little expense.

Having thus described my invention, I claim as -new and desire` to secure byLetters 1. The combination lwith a boiler of vertically arranged steam' pipes and heating ldevices in communicatiomthere'with, of return pipes connected to the steam pipes and also to the boiler Ibelow the water line thereof, connections between the boiler and the steam pipes above the water line for the passage of steam to said steam pipes, a plurality of vent or .stand pipes extendingupward and having theirup'per ends open and-adapted to contain a column of water of agreater height than. the .water line of the boiler, connections forming communication 'between the' standl pipes and the Vboiler below7 the waterline thereof, pipe connections between the stand pipesand said return pipes above the water. lineof the boiler, said connections also forming communication between the standpipes, valves in said ,connections for controlling the same, together with Urshaped vent pipes arranged in the pipe connection between the stand pipes and communicating with the return pipes.
