HEATING APPARATUS.

Specification of Letters Patent.

Patented Apr. 13, 1915.

Application filed .Tune 14, 1911. Serial No. 633,016.

To all whom it may concern Be it known that I, FRANK W. MILLER, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in Heating Apparatus, of which the following is a specification.

This invention relates in general to heating systems and more particularly to systems for heating roundhouses and the like, and aims to produce a system which shall be eflicient and economical in its operation and which will distribute the heat equally from all of the radiating elements and maintain a uniform pressure throughout the system.

One of the primary objects of the invention is to reduce the amount of water which is required in a system of this kind by connecting the pipe which supplies water to the feed water heater with the exhaust pipe of the heating system so that this water is utilized as spray water to condense the steam in the exhaust pipe before it reaches the exhaust pump; the exhaust steam and condensed steam, and the fresh water being then delivered by the exhaust pump to the feed water heater.

Other objects and many of the attendant advantages of this invention will be apparent to those skilled in the art as the same becomes more fully understood.

My invention will be best understood by referring to the following specification when taken in connection with the accompanying drawings illustrating those arrangements of my improved system which appear at present to be most desirable.

Referring to the drawings, the single figure illustrates a heating apparatus embodying my invention.

On the drawings reference character 5 designates a receptacle which in the present instance is designed to be employed as a feed water heater and adapted to be connected with the exhaust of an engine or steam pump by a steam pipe 6. A feed water pump 7, adapted to draw water from the receptacle or heater 5 through a pipe 8, is connected with the power boilers by a feed water pipe 9, through which water is fed to the boilers. The pipe 6 which is connected with the receptacle 5 is adapted to supply steam to the receptacle for heating the water therein, and the surplus steam from the receptacle rises in a pipe 11 from whence it flows through a pipe 12 to the heating elements or radiators of the heating system, the intake end of the radiators being connected with branches 13, one of which is shown on the drawings. Excess pressure in the system is permitted to escape to the atmosphere through a blow-0E valve 1 1 and the supply of steam to the heating elements may be cut ofi by means of a hand valve 15. In case it should not be desirable to deliver the steam into the receptacle 5 to heat the water therein it may be diverted through a branch 16 by opening the valve 17 and closing valve 18.

The exhaust ends of the heating elements or radiators are connected with branches 19 leading from the main return or exhaust pipe 21 which is connected with an exhaust pump 22 adapted to deliver through the pipe 23 into the receptacle or heater 5.

Water is supplied to the receptacle 5 through a supply pipe 21 connected with any suitable source of supply and a predetermined level of water is maintained in the receptacle by means of a float 26 pivoted on the receptacle at 27 and connected by a link 28 to a float valve 29 which is closed and opened as the float rises and falls. Ihe water may be delivered directly from pipe 2% into the receptacle by closing the hand valve 31 and opening the valve 32. In warm weather, when the heating system is not in use, valve 31 is customarily closed and valve 32 is open. When the heating system is in operation, however, I contemplate using fresh cold. water as spray water to condense the steam in the exhaust pipe 21, thereby assisting in the production of the required vacuum in this pipe. With this end in view a pipe 33 in which valve 31 is located is connected at one end with the water supply pipe 2 1 and at its other end with the exhaust or return pipe 21. It will be evident that by opening valve 31 and closing valve 32 the cold water will be delivered through pipe 33 to the pipe 21 to thereby condense the steam in this pipe so that the condensed steam and incoming water may be delivered by pump 22 through the pipe 23 into the heater 5.

In order that the level of the water in the heater may not rise above a predetermined point I have provided an overflow pipe 341 equipped with a shut-off valve 35 which is controlled by a float positioned'within the tank and carried on an arm pivoted on the tank, said arm being connected with the valve by suitable links as shown. When the float rises with the water level above-a predetermined point the valve will be opened and when'the float fallsthe valve will be closed. A valve 37 positioned in pipe 21 beyond the intake to the pump 22,

may be opened for the purpose of draining thesystem and the pump when desired.

It will be manifest from the foregoing that a saving in water is secured by my sys tem in that the exhaust steam from the heating elements is condensed and returned: to the heater and also that the incoming water is utilized to produce a vacuum in the re-' turn pipe so as to relieve the strain on the pump While I'have shown and described a preferred arrangement of pipes it will be manifest that the arrangement can be varied considerably without departing from the spirit of this invention.
