Sediment scraper for water heaters

Application filed May 17, 1922. Serial No. 561,685.

To aU, whom it may concern,· „· z ,, «τ^Λ«7“ ’S’-*-»·'. λJ v ! °f the United States, and a resident 5 S t θΤηίθ’ ^{the county of Athens} and btate of Ohio, have invented certain new and useful Improvements in Sediment Scrapers for Water Heaters, of which the tollowing is a' specification.

My present invention relates generally to heating apparatus and more particularly to a domestic heater, my object being the provision of a simple inexpensive apparatus 2?^{ay be beated} by fv gaseous fuel, in which thorough complete combustion of the fuel is provided for, in which rapid continuous heating of the water is accomplished, in which the discharge of sediment and settling? may be readily and easily effected, and m which automatic control of the heating ²⁰ burner is carried out.
