-- To (17/ whom-i1- may concern:

le itknown that l, Arous'rifs C. DtunnN, Jim, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois have invented new and useful Improvements in Steam-Heating Systems, of which the following is a specification.

This invention relates to steam heating systems, and more particularly to the apparatus associated therewith for taking. care of the steam, air and water of condensation and delivering the water to the source of steam supply or elsewhere as desired.

One of the objects of this invention is to provide means for economizing fuel in systems of this sort, for increasing the etliciency of the steam plant, for dispensing" with iuiliridunl regulating vaives for the radi ators and for simplifying and otherwise improving upon the apparatus for taking care of the steam, air and water of condensation.

To such ends this invention consists inc suitably operated pumping mechanism. con ne'cted with the return pipe of the steam plant, a receiver having a vent. cont-rolled by an outwardly opening check valve, and comuumicating with the return pipe andadapted to receive air and the water of condensntion. and controlling means, actuated by said oscillatory. receiver, for starting and stoppingthe pui'nping mechanism.

The invention further consists in the novelfeaturesof construction, arrangement and combination of parts l'iereinnfter particularly set. forth and defined iu .the claims.

The invention'is clearly illustrated in the drawings furnished herewith, in which:

Figure l is a side elevation of an opparw tus einlmdyiuc the preferred form of the invention, showing the shell of the receiver portly broken} ut Fig. 2 :is a plan View of the parts sem in Fig. l, with the receiver to m ved therefrom, Fig. 3 is an enlarged rerticul cross section 01f the line 3-3 of Fion- 1, Fig. at is an enlarged end view of the controlling device and Rio. 5 is a View of a steam heating: system with my invcnbion applied thereto.

Lct'errinp; to said drawings and particularl to l 5, which illustrates a two pipe svstem. a source of steam supply, shown in the form of an ordinary boiler. A, will be seen. from which earls a main steam pipe I), that connects with radiators or other heatinsr coils. one of which is seen :it C. A. retui-n pipe D. coin-wits with said radiators or coils and conducts the Water of condensation back to the source of steam suppl or elsefor taking care of the steam, air and water of condensation is seen at E. and is interposed in the return pipe as will appear more fully in the course of this specification.

Referring now to Figs. 1 and 2, which illustrate the invention in its preferred form, a sumiorting frame 10, is here shown as com prising two connected beams 10, which-are adapted to support the operative portions of said frame is a pumping mechanism 6, here tively connected with a motor or engine 1'2; preferably in the form of an electric motor. The pump is preferably of the centrifugal type and its shaft 11*, is connected with the shaft 12, of the motor by g), coupling 13. It is to be understood; however, that this particular construction and arrangement -of pumping mechanism is not material to my invention, broadly speaking, but for-ms a simple and effective one for piunping the water of condensation back into the boiler. The return. pipe D, opens into the intake of the pump, at. :5 and the pump discharges int'o the return pipe at 'a from which point said rot-urn pipe leads to the boiler. Supported at the opposite end of the frame 10, is a pivotally sustained receiving tank or receiveifllfi, which is capable of vertical o s cillations upon its fulcrum. When the recei er is in the form of a cylindrical tank; its pivotal point arranged at. one side of its center as seen 1 Fig. l, in order that the watt-r which act *nulates therein may tilt the longer end down into the position shown in dotted lines in said figure.

Various forms of pivotal connections for the art and n very simple one will now be described. The return pipe is shown as exto be discharged. turnpipe underneath the receiver journalcd upon the frame 10, and as shown may he held in pluce ,tnereou simply by strups l5. bolted to the beams and extending over 1 the section (Z, of the return pipe.

vent it the up!) back pressure from the boiler is held back lowering the pressure therein, and drawing live steam into the radiators.

The apparatus is not only applicable to steam heating systems, but to other steam plants where it is desired to collect the water of condensation and return the same to the boiler. 1*urthermore, it is applicable to single pipe systems as well as two pipe Systems, also to high or low pressure systems.

I am aware that various alterations and modifications of this device are possible without departin from the spirit of my invcntion, and I do not therefore desire to limit myself to the exact form of construction shown and described.

I claim as new and desire to secure by Letters Patent:

1. The combination of an oscillatory counter-balanced receiver adapted for communication with the return pipe of a steam heating plant and arranged to be moved from one position to another by the accumulation of Water therein above a predetermined limit, said receiver having an air, vent controlled by a check valve opening toward the outer atmosphere, pumping mechanism, the'intake of which communicates with said receiver, said pumping mechanism operating to intermittently empty said receiver, and a controlling device actuated by the receiver for starting and stopping pumping mechanism. I

-2. The combination with a counterbalanced oscillatory recciverhaving an air vent and a check valve therefor opening out to the atmosphere. said receiver being adapted for connection with the rcturn pipe of a steam hcatinpplant and being" arranged to be moved from one position to another by the accumulation of water therein above a prcdclcrmiuml limit. of pumping mechanism, the intake o'l which comnmnicatcs with said lccci'vcr through a part of said return pipc, a ch ck valve upcning toward the pumping nicchanism. and inlcrposcd in thc rcturn pipc bctwccn thc rccciver and pump ing mechanism, and a controlling device acnalwl by the rcccivcr tor starting and stopping said plunpinp mechanism.

3. The combination of an oscillatory counterbalanced receiver, having an outavardly opening air vent andarranged to be moved from one position to another by the accumulation of water therein beyond a pre-' determined limit, a return 'plpe commun1-' cating with said receiver through a branch, an intermittently operating pump communleating with said return pipe, and operating to empty the receiver, and a controlling device actuated by said, receiver for starting and stopping said pump; said return pipe having check valves openin toward the pump and located on each side of its point of communication with the receiver, said return pipe having also a valve controlled bypass around the checlrvalve between the receiver and pump.

4. The combination of a receiver, ar-

. ranged to receive water of condensation, and having an air vent controlled by an out-- wardly openingcheck valve, :1 return pipe communicating with said receiver, and having two sections out of direct communication with each other, one section continu-' ously opening directly into said receiver, and arranged to deliver water to the same and the other section continuously opening directly out from the receiver and arranged to conduct water away therefrom, pumping mechanism intcr 'ioscd in the second named section of the return pipe and operatingto' intermittentlyempty said receiver, and controlling mechanism actuated by the rise and fall of water in said receiver for starting and stopping said pumping mechanism.

The combination with a receiver, ar-

ranged to receive water of condensation,

and having an air vent controlled by an outwardly opening check communicating with said receiver, and having a section for delivering water to said receiver and assertion forconducting Water away from said receiver, pumping mechanism interposed in the second named section of said return pipe and operating to interinittently empty said receiver, said 'pump ing mechanism having associated therewith a chcclc 'alvc cp'uuing away from the receiver, a valve can rolled bypass included in the return pipe and; extending around said check valve, and controlling mechanism actuated by the rise and fall of the water in the receiver tor starting and stopping the pumping mechanism.
