267,511. Savary, T. March 6, 1926, [Convention date]. Heating buildings. - A hot water heating- system in which the water circulation is accelerated by a pulsometer comprises a waterjacketed boiler having a steam generator V and water elements A, B, C heated by gas burners, a semicircular-sectioned pulsometer P detachably secured to the end of the boiler, and an expansion vessel. The water elements communicate with one another through transverse ducts 1, 2, 3 and at their upper ends open into a waterspace which communicates through a pipe M with the radiators, while the steam generator communicates through branched pipes u with the upper part of the pulsometer and the perforated enlargement e of the pipe f which is connected by a pipe h with the expansion vessel. The products of combustion from the burners pass to the upper part of the boiler in a zig-zag path formed by baffles, while steam passes from the generator V through the pipes u to the pulsometer thus forcing the water through the port j, past the ball-valve c, and through the pipe b to the water element B of the boiler. Water is thus forced from the boiler to the radiators and thence into the expansion vessel and the pipe h as far as the ball-valve g. The uncovering of the port j results in the steam flowing therethrough and reducing the pressure in the pulsometer, and water being drawn into the pulsometer through the perforations in the enlargement e and the opening d in the pipe u. The admission of water into the pulsometer condenses the steam therein and augments the pressure-reducing action of the steam flowing through the part j. The impetus given to the water in the pipe u carries a portion of it to the steam generator V.
