Partnr HERMAN GARBE, OF PANKOVV, GERMANY.
WATERWTUBE BOILER.
SPECIFICATION forming part of Letters Patent No. 688,993, dated Decembe 1'?, 190i.
Application filed May 19, 1900.
To all whom it may concern.-
Beit known that I, HERMAN GARBE, a subject of the King of Prussia, German Emperor, residing at No. l Amalienpark, Pankow, near Berlin, in the Kingdom of Prussia, German Empire, have invented certain new and useful Improvements in Water-Tube Boilers with Wave-Formed Walls, of which the following is an exact specification.
Water-tube boilers in which the top boilers are connected with the bottom boilers by means of series of tubes, so that between each series free spaces are formed, are already known. In the same the heating-tubes are iiXed in projecting parts of wave-formed walls. This arrangement has the disadvantage that `it could only be employed in fiat boilers. EX-
perience has shown that the same arrangement is advantageous to be employed in cylindrical or other arched boilers-tl e., to provide the latter with wave-formed walls into which the heating-tubes `get fixed.
Evidently the fitting of the tubes in boilers with wave-formed walls is very difficult, especially when outside openings for bringing in the tubes shall be avoided. To facilitate the work, I arrange the waves in step-form to each other and in such a manner that upon each projecting wave two or more tubes in longitudinal direction, so that upon each step two series of tubes get fixed. Owing to this arrangement the part to which the heatingtubes get fixed is not only wave-formed, but the waves also arranged in steps vertically to each other. The main purpose for the arrangement of Waves and for fixing the tubes in two series upon this waveformed proj ection is to avoid special openings in the top and in the bottom boilers for bringing in the heating-tubes. The latter can thus easily 'and directly be fixed between the two boilers by inclining the heating-tubes and shifting the bottom extremity of the same through the intervals of the tube series into the bottom boiler and then by lifting the same tubes, so that the topextremities get fixed in the top boiler. The tightening of the joints is effectu ated from the interior of the boilers.
In order to make my invention more clear, I refer to the accompanying drawings, in which- Figure l shows a longitudinal section of a Serial No. 17,299. (Nomodel.)
boiler. Fig. 2 is a cross-section of the same,- and Figs. 3 and 4 are detail views.
The boiler consists of a top boiler Zi and a bottom boiler o. The bottom part of the top boiler and the top part of the bottom boiler are provided with wave-formed walls d 7o, ar-` ranged in step-form, as at r. and L.)
a ct are the heating-tubes, fixed upon the wave-formed projections d of the boilers. From the drawings it will be seen that a fiat part f of the steps is always formed in the middle of each wave projection, into which several heating-tubes are fixed, as shown in Fig. 3. Each wave projection (l can receive two or more tubes arranged in proximity to each other.
It will be easily understood that owing to the arrangement of' two tube series a a in proximity and the series at a certain dis-v tance from each other the tubes can easily be fitted into the boilers through the intervals between the tube series.
The arrangement of fhe'wave-formed walls has not the purpose to increase more the strength of the boiler, since the cylindrical or other arched boilers offer already a sufficient strength for taking up the pressure of the steam, but to facilitate the work of fixing the tubes between the boilers and to avoid special openings.
I-Iaviug thus fully described the nature of my said invention, what I desire to secure by Letters Patent of the United States is- In a boiler consisting of cylindrical top and bottom drums connected by series of tubes, the arrangement in the drums, of waved walls in which the tubes are fitted, each outward projection of the longitudinal waves of both drums forming in cross-section steps, each step taking up one or more tubes and each outer projection taking up two or more tubes in longitudinal direction, whereby between the series of tubes intervals are formed, for the purpose as set forth.
In witness whereof I have hereunto set my hand in presence of two witnesses.
HERMAN GARBE.
