COMBINED STEAM-BOILER AND CRUClBLE-FURNACE.
SPECIFICATION forming part of VLetters Patent No. 280,954, dated July 1Q, 1883.
Application led August 26,1382. (No model.)
Improvements in a Combined Steam-Boiler and GrucibleFurnace, of which the following is a specification. v
My invention relates to combined cruciblefurnaces and steam-boilers, being an improve ment upon that for which Letters Patent to me are now pending. Said' latter application shows and describes a structure substantially similar in general form to that exhibited herein, embodying a crucible-furnace such as are used in brass-foundries and a vertical steamboiler in combination.
My present improvement consists in extend ing the water-jacket of the Crucible-furnace inward above the grate to and surrounding the accesslopening, and, further, in providing a series of circulating-pip es within the fire-box, all as hereinafter more fully explained.
My invention is illustrated in the, accompanying drawings, exhibiting in Figure l a vertical section of my improved apparatus complete; in Fig. 2, a plan section of the saine, taken through the fire-box andthe circulatingtubes; and in Fig. 3, an external elevation of the apparatus complete. Y
In the drawings referred to, A designates the boiler portion of the apparatus, and B the furnace portion, both being united as one structure, having a common water-space surrounding the fire-boxes of both, and being provided with grate-bars and exit-dues extending upward through the boiler.
The first part of my invention consists in arching the inner wall of the furnace re-boXV b, as shown 'in Fig. l at c c, toward and surrounding the opening d, which enables me to increase the diameter of the water-shell B and of the fire-box without enlarging the aperture d or the removable cover e. By this means a considerable economy. of heatis effected by the absorption and reflection of that portion radif ated upward.
In connection with this improvement I introduce a series of short pipes, f, arranged concentrically within the fire-box opening through the arched portion c o of the inner shell around the aperture d, vertically. At their lower portions the pipes are preferably turned outward and enter the shell above the lining g,- or they may extend downward behind or through the linings and enter the shell below. iOpposite the pipe-openings in the eX- ternal shell are corresponding openings,which are provided with screw-plugs h, and thus afford a means of access to the pipes for cleansing when necessary. In practice, however, this is seldom required, as the eiiect of heat and the differences in temperature causeacirculation of Water in the tubes f, which prevents any deposit of sediment therein.
By these improvements the steaming capacity of the apparatus is very much enhanced and a saving in fuel effected.
I claim as my invention and desire to secure by Letters Patent- In a Combined Crucible furnace and steamboiler, the water jacketed Crucible-furnace, constructed with its inner shell arched inward toward the coveropening, and provided with a series of circulating-pipes arranged vertically around the nre-chamber and opening vertically through the arch ed shell above and radiallythrough the shell below, in combina tion with removable plugs closing access-openings in the outer shell, arranged to register with the openings of the circulating-pipes through the inner shell, substantially as and for the purpose specified.
In testimony whereof Ihave hereunto set my hand in the presence of two subscribing-witnesses.
