UNITED STATES JOE CONFEB, OF NEW YORK, N. Y.
BOILER AND WAT HEATER.
" Application filed January 15, 1923. Serial no. 012,029.
To all whom it may concern:
Be it known that 1, Jon Colman, a citizen of the United States, and a resident of the city of New York, borough of Manhattan,
6 in the county and State of New York, have invented a new and Improved Boiler and ater Heater, of which the following is a full, clear, and exact description.
The present invention relates, to new and 10 useful improvements in water heaters and it pertainsmore particularl to a device for utilizing waste heat in t e chimney of a boiler.
It is one of the primary objects of the invention to so construct a device of this character that it may be attached to the chimney of a boiler in such a manner as to utilize the waste heat units for the purpose of heating water.
It is a further ob'ect of the invention to so construct the device that an" unobstructed circulation of water is had at all times.
It is a further object of the invention to employ such a construction for the purpose of reducing the fuel consumption necessary for heating water in apartments and tenement houses.
With the abve. ,and other objects in view, reference is had to the accompanying drawings in which the figure is a view partly in elevation and partly in section of a device constructed in accordance with the present invention.
Referring to the drawings, the reference numeral designates a boiler of any desired type, and leading to said boiler is a cold water pipe 6. Leadin from the boiler is a water pipe 7, and said latter pipe is employed to conduct heated water or. steam therefrom as the case may be. The cold water pipe 6 is provided with a check valve 6' to prevent backing up of the water.
The chimney 8 of the boiler 53 has a horizontal section 9 attached to the chimney in such a manner as to provide a clean-out portion 10. The horizontal portion 9 is provided with an elbow 11 and a projecting portion 12 within which is mounted a danfiper 13. Surrounding the chimney, prefera ney, said y the horizontal section thereof, is a erence character 15.
by the ref The pipe 7 heretofore mentioned communicates with the drum as at 16, and a pipel? is emplo ed for connectin gipe 6 with the drum 14. adin rum 14 is a pipe 18, and such pipe is connected to the hot water main 19 as shown.
Connected to the pipe 7, as at 20, is a pipe 21 which extends into the horizontal section 9 of the chimney throughout the lengthof the drum and has its other end connected as at 21", to the drum. By this construction it is apparent that water in the drum will maintain the pipe 21 full at all times and that as the products of combustion pass through the chimney the heat units thereof will serve to heat the water in the pipe 21, thus utilizing what is ordinarily waste heat in devices of this type.
As the water in the pipe 21 is heated, a circulation through the pipe 21 and the drum 14 is maintained thus insuring at all times hot water in the drum 14.
From the foregoing it is apparent that the products ofcombustion assmg throu h the chimne serve to heat t e water in t e drum 14, t rough the medium of thepipe 21, and it has been proven by actual experiment that by such a construction the consumption of coal within the boiler 5 is meterially reduced.
What is claimed is:
In combination with a boiler and its chimney, a water drum surrounding a portion of said chimney, said chimney passing throu h the water drum, a pipe eading from t e boiler to the water drum, and a second pipe connected to said first-mentioned pipe at a point exterior of the water drum and chimsecond mentioned pipe passing into the chimney extending longitudinally thereof to a point beyond the endof the water drum and then passing through the chimne and connected to that end of the water rum opposite to the end to which the first-mentioned pipe is connected.
the cold water from the
