which such a heating system must at times re-A spond.

In steam heating systems having the usual steam boiler and furnace therefor and wherein there vare a considerable number of radiators which are connected to a relatively long.` supply pipeline or section for receiving steam from the boiler and wherein there are a lesser number of radiators connected to a relatively short supply pipe line orsection for receiving steam from the boiler experience has developed the fact that frequently the heating effect of radiators supplied through the long pipe line-and particularly of the radiators more remote from the boiler as for example the radiators inthe upperpart of a building-is relatively small `or deficient due to insufiiciency in the supply of steam thereto and any object of the present invention is to employ an auxiliary heater and to incorporate it inthe heating system in such a manner that it is functionally associated with the water and steam section of the boiler, with the furnace for the boiler,

and with the long supply pipe line or section so that the steam supply to the long pipe line will be augmented and insured whereby the heating effect of each of the several radiators connected to the long supply pipe line or section will favor ably compare with the heating effect of each of the radiators connectedto the short supply pipe line or section.

A further object of the invention is to provide l an auxiliary heater of this character adapted/to utilize the heat ofthe smoke andvhot gases and other products of combustion which pass off to the chimney or nue andv the heat of which is usually lost aftersuch products of combustion leave the steam boiler of the heating system.

yA further object of the present invention isto provide an auxiliary heaterj adapted to permit steam to enter the line to be reinforced and at the same time permit any water of condensation to drain back into the steam boiler.

With; these and other objects in view, the invention consists in the construction 'and novel combination and arrangement of parts hereinafter described, illustrated in the accompanying drawings, and set forth in the claims hereto ap pended, it being understood that various changes in the form, proportion, and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit of the invention or sacricingl any of the advantagesI thereof.

-` In the drawings: v

Figure l is a side elevation of an auxiliary heater constructed in accordancewith this. in-

vention and shown applied to a steam heating Fig. 2 is a vertical sectional viewtak'ensubstam tially on the line v2 2 of Fig. 1, the steam boiler `being shown in elevation.

FigfS is a diagrammatic view illustrating the hook up of the several members or parts of a AY'-'steam heating system realizing the invention.

In-this figure, the! casing construction for the auxiliary heater thereof .is shown witha portion of the casing construction removed whereby the auxiliary heater. or auxiliary heater element appears in full lines. For the purpose of better illustrating the invention the parts in this figure are shown in the samehook up as in the other figures but in this Fig. 3 the parts occupy a somewhat diiferent physical position relative to each other from that shown in the other figures.

`In the accompanying drawings, in which is illustrated the preferred embodiment of the invention, 1 designates a steam boiler and furnace construction provided at the top with riser'pipes 2 and 3 leading from the usual steam and water space of `the boiler and with 'a smoke pipe or ue extending'from the furnace Asection of the boiler and furnace construction to the chimney -provided therefor. f-The smoke pipe or flue comy prises 'as a. part thereof a drum or casing 5 wherein Athere is encased an auxiliary heater,

or auxiliary heating element vor section,l 6. @The auxiliary heater 6 isof radiator formation, and while one section or unit is illustrated in the accompanying drawings,v the auxiliary heater may comprise any number of such sections, as will be readily understood. The pipe connections ofthe smoke pipe may connect the drum or casing 5v with the steam boiler-1 and with the chimney or ue, so that when the smoke, hot gases and vother products of combustion, which usually pass from the steam boiler through thel chimney or flue, pass into the smoke pipe, they are forced to pass through the drum or casing 5 and impinge against the auxiliary heater. Owing to the auxiliary heater being of radiator formation, the smoke and other products of combustion pass through and around the auxiliary heater, so that the latteris entirely subjected to the action kofthe heat of the smoke and other products of combustion.

The riser pipes 2 and 3 are respectively con-v lreference to the eiciency of the other short line, 8. The long and short lines 'l and 8 are shown in the accompanying drawings as extending substantially horizontally from the riser pipes 2 and 3-but as is well recognized in practice these should slightly incline downwardly towards the riser pipes 2 and 3 to permit drainage back towards the riser pipes 2 and B-and said lines '7 and 8 are connected with drain pipes 9 and 10,which conduct any water of condensation in the lines 7 and 8 back to the steamf boiler to prevent such water of condensation from interfering with the passage of the steam through the lines. The drain pipes 9 and 10 .are vertical and the auxiliary heater' 6 is connected at the top at one end by a pipe 11 with the drain pipe,'by a T coupling 11e. at a point above the water line of the steam boiler l. The pipe 11 is preferably located above the top of the steam boiler, and it is preferably provided with a thermometer 12. Steam from the auxiliary heater will pass out from the top of the heater through the pipe 11 to the upper portion of the drain pipe 9, and will then pass upwardly through the drain pipe and enter the relatively long line 7 and increase the heating eiiiciency of the same. By means of the auxiliary heater steam of a relatively high temperature is introduced into the pipe line 7 to supplement the steam which passes directly from the boiler into the line through the riser 2.

The auxiliary heater is supplied with water by the return pipe 13 from the radiators, and the water of condensation from the radiators thus supplied to the auxiliary heater is then heated, and that portion thereof which is converted into steam and delivered to the pipe line 7 ows from the auxiliary heater through the pipe 11 and down the drain ypipe 9 to the lower portion of the steam boiler, viz. to the vWater space of the steam boiler, and is delivered to the latter in a heated condition, ,thereby increasing the efficiency of the steam boiler by introducing preheated water into the same instead of water at a relatively low temperature, as is the case where the return pipe is connected directly with the steam boiler and the water of condensation not preheated before being delivered to the steam boiler.

The return pipe rextends to a point below one end of the auxiliary heater and is connected with the same by a vertical pipe 14 at the lower corner of the auxiliaryheater at apoint diagonally op.- posite the outlet 15 witlrwhich the pipe 11 is connected. The auxiliary heater is provided at the other end with a cap 16 for closing the outlet 17 when the latter is `not employed. The return pipe 14 and the discharge pipe l1 are connected with the auxiliary radiator by suitable couplings, and the said auxiliary heater is supported by spaced

vertical standards

18 and 19 which are provided at their lower ends with anged

caps

20 and 21 suitably secured to the oor or other support upon which the steam boiler is mounted. The

vertical standards

18 and 19 preferably consist of pipes which are suitably plugged. The standard 18 is relatively short and is coupled to the lower end of the vertical return pipe 14 at the point where the same is connected with the radiator return pipe 13. The standard 19 is suitably coupled at the other side of the auxiliary heater opposite to the point where the return pipe ld-is connected, and the spaced vertical supports provide a strong, durable structure for the auxiliary heater. The auxiliary heater is preferably arranged close to the steam boiler, as clearly illustrated in Fig. 1 of the drawings, to subject it to the intense heat of the products of combustion passing from the steam boiler to the, chimney or flue, but this auxiliary heater does not affect the construction of the boiler, being arranged in the smoke pipe thereof. pipe connection extending from the casing or drum 5' may be provided not only at the upper but at the lower portion thereof, and the relatively long pipe line extending from the riser 2 is preferably connected to the said drum so as to thoroughly subject it to the heat of the products of combustion passing through the smoke pipe.

What is claimed is:

1. In a steam heating system, in combination, a steam boiler having riser pipes extending upwardly from the top thereof, a long pipe line having a substantially horizontal section connected to one of the riser pipes, a short pipe line having a substantially horizontal section connected to another of Vthe riser pipes, radiators, some of which radiators are connected to and supplied with steam from the long pipe line and others of which radiators are connected to and supplied with steam from the short pipe line, vertical drain pipes, there being a drain pipe for and corresponding to each of said pipe lines, each of said drain pipesv being arranged adjacent the steam boiler and extending from a horizontal section of the pipe line to which it corresponds to the lower portion of the boiler for delivering waters of condensation draining therethrough back into the water-containing section of the boiler, a smoke conduit extending from the combustion space of the steam boiler, a drum or casing provided in or by said smoke conduit, an auxiliaryheater arranged within the drum or casing in the path of the smoke and other products or" combustion passing through the smoke conduit,` a discharge pipe leading from the upper or steam delivery portion of the auxiliary heater and extending to and communicating with the drain pipe of the relatively long pipe line, said discharge pipe being connected to said last'mentioned drain pipe at a point whichV is above the water line of the boiler, and a radiator return pipe for connecting the several radiators to the auxiliary heater at the lower portion or water intake end thereof.

2. A steam heating system asderlned in and by the preceding claim, wherein the return pipe for the radiators is connected to the auxiliary heater through the medium of a vertical pipe located below the Vauxiliary heater so as to deliver return water upwardly into the bottom portion of the heater and at a point directly opposite the place where the steam and any water leaving the auxiliary heater pass upwardly therefrom through the discharge pipe that is connected to the drain pipe connecting the long pipe line and the lower portion of the boiler and wherein the auxiliary heater is supported on vertical standards, one of which standards serves as said vertical pipe leading into the auxiliary heater.
