HOT-WATER-CIRCULATING SYSTEM;
Specification of Letters Patent.
latentedfiept. ii, iaia.
Application filed August 8, 1913. Serial No. 783,781.
To all whom it may concern Be it known that 1, WILLIAM DEW KNIGHT, a citizen of the United States, residing at Santa Monica, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Hot-lVater-Girculating Systems, of which the following is a specification.
lhis invention relates. to water heating devices or boilers and more particularly to a hot water circulating system to be herein-- after fully described.
The primary object of the invention contemplates the provision of a simple and in expensive boiler wherein a supply of cold water is'circulated or drawn through a suitable compartment provided therefor within the boiler; then heated exteriorly of the boiler by any suitable range or other heat source, and finally conveyed back again into a second or the main compartment of the boiler in'a heated state where it is free to be withdrawn when desired, this arrangement effecting a continuous water circulating system for replenishing the hot water supply as occasion demands.
A further object of the invention resides in the provision of a specially constructed boiler, simple in design and capable of being employed in connection with any suitable range, stove or other heat source susceptible of having a boiler connected'thereto.
The above and additional objects are accomplished by such means as are illustrated in their preferred embodiment in the accompanying drawings, described in the following specification and then moreparticu;
larly pointed out in the claim which is appended'hereto and forms a part of this application. p
With reference to the diawings, wherein I have illustrated the preferred embodiment of my invention, as it isreduced to practice, similar reference numerals designate corresponding parts; the view in the drawing being a vertical sectionalview of the boiler,
arts being shown in elevation, and the boiler compartments being only partly filled so as to better illustrate the interior structure'thereof.
Referring now to the description of the drawings, the numeral -1 designatesthe boiler in its entirety having a cylindrical shell 2 extending concentrically throughout the entire length thereof, the said shell being provided with outwardly d rected flanges 3 at each end for securely fastening the same 1n proper place within the boiler. A cold water inlet pipe 4: discharges into a suitable compartment 5 formed by the shell 2 from the top of the boiler, the said inlet pipe f having an extension 6 arranged within the compartment 5 for conveying the water into the said compartment and preventing the rise of water therein above the mouth of the said extension. A cold water outlet pipe 7 is secured to the boiler 1 at the opposite end thereof from that of the inlet pipe 4 or in axial alinement with the extension 6, the said outlet pipe 7 leading into a suitable tank or other receptacle arranged within a range, stove or like heat source, the latter being omitted from the drawing. From the heat source, a hot water inlet pipe 8 conveys the water in its heated state again into the boiler 1, the said pipe 8 discharging into a hot water compartment 9 formed within the boiler and surrounding the cold water compartment 5 thereof, this arrangementsupplying the boiler with an unlimited supply of hot water as the same is replenished through the inlet pipe 8 as quickly as it may be withdrawn from a suitable hot water outlet pipe 10, the latter having an extension 11 extending into the interior of the boiler to a point near the base thereof.
To allow the steam generated by the hot water to escape from the compartment 9, an opening 12 is formed within the shell 2 near the top thereof, thus permitting the steam to enter the cold water compartment 5 where it is condensed by the inflowing cold water, such condensation allowing the hot I water, when not in circulation, to be maintained at a boiling temperature.
A, drain'pipe or valve 13 is open'to the boilerat the base thereof for withdrawing the contents of the compartment 9 when desired. Pipe 7 is open to a branch pipe 14: (a valve being arranged at the point of in-, tersection) whereb to provide 'for a discontinuation of the water supply to the heat source, if desired.
It will be seen from the above, taken in connection with the accompanying drawings, that the temperature of thecold water as it passes through the compartment 5 is increased by reason of the'heatedstate of v the compartment wall or shell 2; and that an unlimited supply of hot watermay be M.
to I
had, as hot water is supplied to the hot water compartment 9 as fast as it is withdrawn therefrom through the outlet pipe 10.
It will be understood that the above description and accompanying drawings comprehend only the general and preferred embodiment of my invention and that various minor changes in details of construction, proportion and arrangement of parts may be made within the scope of the appended claim and without sacrificing any of the advantages of my invention.
Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is In a hot water circulating system, a boiler, a shell extending longitudinally throughout the length of the boiler for dividing it into a cold water compartment and a hot water compartment, the said shell having an opening formed therein at a point adjacent the boiler top, a cold water inlet pipe extending into said cold water compartment to a point below said opening, a cold water outlet pipe leading from said cold water compartment, a hot water return pipe discharging into the hot water compartment of the boiler at a point intermediate the boiler terminals, and a hot water outlet pipe leading from the boiler and extending thereinto to a point below the point open to the hot water return pipe, as and for the purpose set forth.
n testimony whereof I afiix my signature in presence of two witnesses.
WILLIAM DEW KNIGHT.
