OSWALD FLAMM-AND FRIEDRICH ROMBERG, OF CHARLOTTENBURG` l GERMANY.
WATER-TUBE BOILER.
Original applicationled September 15, l 90 5, Serial To all whom it may concern:
Be it known that we, OswALD FLAMM and of Prussia, German Emperor, and residents of Charlottenburg, near Berlin, Kingdom of Prussia, German Empire, have invented cern tain new and useful Improvements in Water- Tube Boilers, of which the following is an eX- act specification and which forms an eliminated part from our pending application, Serial No. 278,688, filed September 15, 1905.
Our invention relates to wateretube boilers consisting of one or more lower chambers, one or more upper chambers, and a number of tubes around these chambers connecting them, in combination with a circulating pump or umps, by means of which an artificial acce erating water circulation is maintained in the long and narrow water-tubes, the diameter of which Vcan be very low without fear of limiting or preventing the necessary speed of circulation of the water,
It has been heretofore proposed to use long narrow water tubes in combination with steam-boilers. However, in these tubes an artificial water circulation has not been maintained or the boilers have not been divided into special lower and under boilers, being connected by the long narrow water-tubes.
The present invention provides a tubular boiler of special construction, in connection with which a circulation pump or pumps are intended to be used. The lower and upper chambers of the boiler arearranged and connected with each other in a s ecial manner, and long water-tubes of smal diameter are placed around the chambers to save space without the necessity of decreasing the evaporative capacity.
In order to make our invention clear,reference is made to the accompanying drawings, in which- Figure l is a vertical longitudinal section of our improved boiler. Fig. 2 is a fragmentary horizontal section, and Fig. 3 is a fragmentary sectional view in detail of a special connection between the lower and upper chamber.
The small boiler illustrated consists of an upper chamber m', a lower chamber m2, helical water-tubes of great length and small diameter arranged in two concentric series g Specification of Letters Patent.

q2 around the lower and upper chamber. Each tube of the series g2 is connected at s with the upper chamber land at s2 with the lower chamber and each tube of the series q at S3 and s4 with the upper and lower cham bers, respectively. A shell h incloses the whole boiler, being provided at its lower part with the fire-grate p. The upper chamber m is in communication, by means of the tube r3, with the circulating-pump, (not shown in the drawings,) while from the circulating-pump the tube 1" passes to the lower chamber. The lower and upper chambers are formed, according to our invention, by a single tubularshaped receptacle n, divided into two parts, according to one construction, by a diaphragm t, screwed into an annular projection n Semiglobular caps k lc are screwed to the receptacle fm at its top and bottom for the purpose of enlarging the capacity of f the boiler.
The boiler as above described operates in the following manner: The water to be evaporated is forced by a circulating pump through the tube 1" into the lower chamber m2, flows then through the series g g2 of water-tubes, and passes into the upper chamber as steam, which is taken off by means of the outlet-tube r2. The superfluous water not evaporated is drawn offthrough the tube r3 by the circulating-pump and again passed, for a second time, through the boiler.
In Fig. 3 is illustrated a modified mode of connecting the upper and lower chambers m m2, which in this case are separate receptacles. m is placed with its bottom o directly upon the top plate fv of the lower chamber m2. The two plates o 'v' being provided with flanges w, are united by means of bolts Having thus fully described the nature of our invention, what we desire to secure by Letters Patent of the United States isl. A water-tube boiler having an artificially-accelerated circulation, comprising in combination, a tubular receptacle divided by diaphragm into two parts and constituting the upper and lower chamber of the boiler, concentric rows of helical long and narrow water-tubes situated around said chambers and connecting the lower and upper chamber of the boiler.
2. A water-tube boiler having an artifi- IDO cially-accelerated circulation, comprising in combination, a tubular receptalefdivided by diaphragm into tWo parts and constituting the u pperandlower chambenof the boilenthe upper I chanber `and 'the flower'chanberb'eing provided with a ilanged bottom and top p'late respectively, to enable them to be connected, and concentric rows of helical Water-tubes situated around said chambers and connecting the lower and upper chamber of the boiler.
In Witness whereof We have hereunto set our hands in the Epresence of tWo Witnesses.
