Application filed June 8, 1897. $erial 110,689,889. (1101110691.) Patented in Belgium May 28, 1896, No. 121,612; in Eng land May 29,1896, No. 11,738 i in France June 18, 1896,1To. 257,322; in Hungary September 23, 1896, No. 7,504, and in Austria February 27, 1897, No- 47/615.

T0 CLZZ whom it may concern:

Be it known that we, J EAN BAPTISTE LooUET and JEAN BAPTIsTE KETELAIR, subjects of the King of Belgium, residing at Antwerp, Belgium, have invented certain new and use ful Improvements in or Relating to Steam- Generators, (for which we made application in Belgium, No. 121,612, dated May 28, 1896; in France, No. 257,322, dated June 18, 1896; in Great Britain, No.11,733, dated May 29, 1896; in Austria, No. 47/615, filed September 23, 1896, granted February 27, 1897, and in I-Iungary, No. 7,501, dated September 23, 1896,) of which the following is a specification.

This invention relates to steam generators or boilers which ofier great advantages as compared with boilers used hitherto by reason of their providing a much quicker and more economical vaporization of water. i

A steam-generator according to the present invention is represented in the accompanying drawings, in which 7 a Figure 1 is a longitudinal section, the arrangement inside being shown in elevation.

Fig. 2 is a front view, and Fig. 3 a back view, of the steam-generator.

The distinguishing features of the new steam-generator consist of a furnace-chamber A, made in one with the outer boilershell B, in the manner shown in'Fig. 2, and a combustion-chamber 0, arranged in the inte rior of ,the cylindrical body of the boiler in such a manner as to have its outer surface entirely surrounded by water. In this combustion-chamber, which is supported by suit able cross-stays D, takes place the first deflection of the flames, which pass through a preferably oval flue E into a second combustion-chamber F, constructed and arranged like the first one, C. This second combustion-chamber F, in which the second deflection of the flames takes place, is connected to the front plate J of the boiler by stays G, and is accessible through a tube 11, closed at the front plate by a manhole cover K. The

chamber F is connected to the furnace-chain:

ber A by a vertical stay L and is in ooInmunication with the smoke-box M of the chimney N by means of two or more flue-tubes in. 'tudinal stays S, Fig. 1,.and a steam-dome'T,

which are secured to the combustion-chamber F at one end and to the back plate P of the steam-generator at the other.

The tube E, connecting the first and second chambersO and F, terminates in the latter on the same wall as the tubes 0 O,.connecting the combustion chamber F with the smoke-box; but the tube E and the tubes 0 O intersect, so that the discharge-opening at the tube E into the chamber F is substantially on a higher level than that of the gasoutlet openings of the tubes 0 0. Owing to this arrangement the flames coming out from the tube E are obliged to strike against the front wall of the combustion-chamber F, and

and products of combustion follow the path indicated by the arrows before escaping through the chimney, these reversals of flow taking place in the combustion-chambers O and F, which are readilyaccessible for clean- The generator is completed by longiand it may further have any of the usual fittings-such as water-gage,steam-gage,safetyvalve, steam-whistle, and drain-cock-and may be supported on, say, three cast-iron bearers U. E

The shape of the furnace-chamber or fine A, which is of great importance, is shown in Figs. 1 and 2. It will beseen that the plate forming the furnace-chamber is bent insuch manner that its two extremities Vjoin the cylindrical boiler-shell at a distance of, say, fifty centimeters from each other, so that this shell will be continuous with the wall of the furnace-chamber orflue A. A better utilization of heat generated in the furnace-chamher and a more practical arrangement of the ash-pit than has hitherto been attainable is thereby attained. All the parts of the boiler are arranged so as not to present any difficulties in construction or in cleaning and repairing and can be made of any desired dimensions.

WVe claim 1. In a steam-generator, the combination with the boiler-shell B bent inwardly at its lowest part to form the furnace-chamber A,

of a combustion-chamber arranged toward the back of the boiler and at a distance from the walls thereof adapted to be surrounded by water, a combustion-chamber arranged toward the front of the boiler above the chamher A and in position to be surrounded by water, a tube connecting the said combustion-chambers, and a tube to conduct products of combustion from the front combustion-chainber.

2. In a steam-generator, the combination with the boiler-shell B bent inwardly at its lowest part to form the furnace-chamber A, of a combustion-chamber arranged toward the back of the boiler at a distance from the walls thereof adapted to be surrounded by water, a combustion-chamber arranged toward the front of the boiler above the chamher A in position to be surrounded by Water, a tube connecting the two combustion-chambers, a smoke-box, and tubes leading from the front combustion-chamber to the smokeadapted to be surrounded by water, a tube E connecting the chambers O and F and entering the latter chamber toward its upper end, and tubes 0 leading from the chamber F, at a point below the end of thetube E and crossing the latteras described.

In witness whereofwe have hereto set our hands in the presence of the two subscribing witnesses.
