whom'it comm. -Be it known that I, Gnosos F. Parrnnson,

a eitizen of the United States, residin at a "Baltimore, in the State of Maryland, ave invented certain new and useful Improve-- ments inFeedWater Regulators, of which the followingjs as cifica'tion.- 'j This invention re ates to improvements in Y water level regulatorsand has for its object 10 to provides; comparatively sim le device of this "character which will be de icatein opand which will maintain the level'of ater inboilers at practically a predetel-mined point. j The invention consists in the novel construction, combination and arrangement of the parts hereinafter described and claimed reference being made .to the accompanying V drawings wherein, Figure 1, is adiagrammatic view of a boiler; a water column and regulating devices connected thereto-and of a pump for supplyin water to the boiler, and Fig. 2, is a vertica sectional view through the aux: iliary generator for heating water by the action of steam from the boiler'to generate a ressu're for actuating the regulator valve.

eferring to the designates a steam boiler; 2, the water col- 3, the steam pi e between the boiler and water. column an 4, a water pipe connecting the boiler below the water line and the water column; The water column or-reoe taele, 2,,is provided with the usual'glass Ee, 5,-to shohv the actual water level in theboilerg W .An auxiliary. enerator, .6, is provided and reference to ig; 2,.it will be noted that in the present instance this generator con} 40 sists of a casing having a lower compartment an; upper compartment, 8,. with a cor rugated partition, 9,= separating said" two clam in'g action ot-flanges, 10, on. the casing formed in two parts; A. steam pipe,-

A pi ,14, communicates w th the upper eompar ment, 8, of the auxiliary generator and extends vertically therefrom and is provided with a coil, 15, between its lower and upper ends and said latter. end, 16, entersthe upper side of a small corrugated-reservoir, 17. Another pipe, 18, communicates also with the upper compartment, 8, of the said generator and enters the lower side or bottom of the reservoir, 17, and, this pipe'a-l'so has a coil therein. Thus it will be-seen that a circulating system is provided'tha-t includes the upper. compartment, 8 pipe, 14, reservoir, 17 and pipe, 18. By reference to Fig. 2 it will be noted that short nipples,'19, are screwed into the lower ends of pipes, 1d,. and, 18, and have lower notched ends, 20, which terminate in close proxiniity. to the upper side of the corrugated partition, 10, in the compartment, 8,

Theauxiliary generator, 6, has a central dome, 21, which communicates with the u per cQn1partment,-8, andla pipe,-22, leads from said dome and communicates with a shortipe, 23, that enters the upper side of a iaphragm' regulator, 24, having the usual flexible 'diphragm', 25,'-the short pipe, 23, terminatin above the upper side of'said diaphragm. y this arrangementcommunication will be maintained between theupper compartment, 8, of the auxiliary generator and he upper side of the diaphragm in the regulator, 24.
