STEAM GENERATOR.

Specification of Letters Patent.

Patented May 16, 1922.

Application filed July 26, 1920. Serial No. 399,028.

To all column. it may crmcci-a 1 Be it known that I, Jon B. Roernmo; a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and use ful Improvement in a Steam Generator. of which the following is a specification.

This invention relates to new and useful improvements in a steam generator.

One object of the invention is to provide a steam generator of the character described wherein electrical coils are employed for generating the steam and which equipped with means ili'orcontrolling the admission of water into the boiler and. the delivery of steam therefrom to the pump.

Another object is to provide a device of the character described wl'iereby the exhaust steam from the pump may be coudenserfl and used again, thus economizing in the consumption of water.

A. still further feature of the invention resides in the provision of a steam generator which is simple in construction and automatic in operation.

With the above and other objects in view the invention has particular relation to certain novel features of construction, operation and arrangement of parts. an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of the device showing the boiler in section.

Figure 2 is transverse sectional view of said boiler. 1

Figure 3 is an end vlew thereoi, and Fig ure 1 is a sectional view of a governor employed.

Referring now more particularly to the drawings wherein like numerals of reference designate similar parts in each of the Figures, the numeral 1 refers to cylindrical tank forming a boiler. Vithin this tank there arranged one or more electrical heater coils 2, which. are enclosed. within the casing 3. having the pa11-shaped covering 1. This casing is attached at one end to the corresponding end of the boiler and its other end is supported upon the tripod. 5 which is located within said boiler. The heater coils 2 are connected to a source of supply through the wiring 6, which is provided with the usual switch 7. Leading from the bottom of the boiler there is a drain pipe 8, which is controlled by a suitable valve 9.

Entering the top of the boiler there is a water inlet pipe 10 which leads from the pump 11 and is controlled by the check valve 10 and this inlet pipe is connected to the long perforated nozzle pipe 12, arranged within the boiler above the electrical heaters 2. The numeral 13 refers to awater line which is connected to a water pressure system, and which enters the inlet pipe 10, and iscontrolled by the shut-off valve 14;. Leading from the water pipe 13 there is a pipe 15 which discharges water into the cistern 16 and is controlled by the valve 17. p A steam line 18 leads from the boiler and through it the steam is conducted from the boiler to the steam engine (not shown) or to the mechanism to be driven thereby. Leading from the steam line 18 there is a steam pipe 19 which is connected to, and drives the ppmp l1 and is controlled by the valve 20. ..here is another steam pipe 21 which leads from the steam line and is connected to the steam pipe19 beneath the valve 20 and this pipe 21 is controlled by the valve 22 and is equipped with a governor 23 of any suitable type which is actuated by pressure from the water pipe 10 through the pipe 24, which is connected to said water pipe and to said governor. The pipe 19 is utilized for starting the pump and may be also used in case the governor 23 should refuse to act. The water pipe 10 carries a suitable gauge 25 and is equipped with a shut-off valve 26 and a steam. controlled governor 2'? which is actuated by steam pressure through the pressure line 28, which is connected to said governor, and to the steam line 18. The steam line carries a suitable gauge 29 and the boiler is equipped with a safety valve 30 of any conventional construction.

In operation the valve L1- is first opened and the switch 7 closed. Water will thus be admitted through the water line 13 and inlet pipe 10 and will drip down into the pan 4 and be converted into steam. When there is sufficient pressure to operate the pump 11, the valve 20 is opened and the pump is then started. The valve 17 is then opened and the tank 16 filled with water and the valve 141 closed. Water will then be forced through the inlet pipe 10 by the pump 11 into the boiler. Often it is necessary to pump the water under force in order to over come the steam pressure within the boiler. The governors 23 and 27 are set to operate at a certain fixed pressure and should the fixed pressure be exceeded the supply of water will be automatically out off by the governor 27 and the steam pressure thereby reduced and the Operation of the pump is similarly controlled by the governor 23, which controls the supply or steam to the pump, and is actuated by water pressure through the line 2 Water-is supplied to the. pump from the cistern 16,,through the water line 29, and leading fromthe exhaust steam chamber of the pump there is a steam line 30 which conducts the exhaust steam into the cistern 16 where it'is condensed to be re-used and means thus provided for economy in the use of Water.

What I 'clai-misc 1. A steam generator including a boiler, a pump, a water pressure line connected into the boiler, a cut off valve controlling said pressure line, a water line leading, from the pump and terminating inthe pressure line between the valve and boiler, a steam line leading from the boiler and formed into branches which unite into a, common line Which is connected to the pump through which steam is delivered to the pump for operating the same, shut off valves controlling said: branch lines, a water cistern, a pipe connecting the cistern with the intake ofthe pump, an exhaust steam line leading livered to the pump for operating the surue.

governors actuated by steam and water pressure, respectively, and autoimitieally (0H- trolling the passage 0] water and steam respectively, through said steam line and water line, a water cistern, 11 pipe connecting said water cistern with the intake of the pump and an exhaust steam line leading; from the exhaust pipe of the pump und entering said cistern.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
