cHAELEs'wiLLIAM SIEMENS, oEwESTMiNsTEE, ooUNrY o'E- MIDDLESEX, ENGLAND.` y
Toall whom fit may concern 'ROTA-mwa i SPECIFICATION forming part of Letters Patent No. 241,515, dated May 1'7, 188l1.` y
Application filed Jury 11,1880. (Nomoaei.) mantena England December 16,1879.
Be it known that I, GHELES WILLIAM SIEMENS, of Westminster, in the county of Middlesex, England, have invented new and useful Improvements in Rotative Furnaces, for
which I have obtained a patentin Great Brit-V ain, No.4 5,150, bearing ldate the 16th of December, 1879, and for which I made application for a patent in France on the 16th ot' June, 1880.V
The following is a specification of my in vention My invention relates to means for remedying defects in existing forms of rotative furnaces, and at the same time providing protection for the throat of the furnace,'which vis most exposed to the destructive action ofv the heat, and insuring the division ofthe puddled mass into balls of convenient sizefor` handling. For this purpose I provide at the back of the rotating vessel an annular or other shaped casing or'casingssurrounding the throat, and from such casing or casin gs I lead two or more pipes along and within thegrefractory lining of vthe vessel to atrunnion-joint at the center of the front of the vessel. -Inthis trunnionjoint I provide a facing, like that of a rotating slide valve, with ports communicating with those-pipes,and also with supply and discharge pipes connected to thetrunnion--the former from a water cistern, pump, or accumulator, and the latter leading to a drain or other o utlet. As the vessel revolves water flows bythe 1 trunuion-ports alongsome lof the pipes tothe casing or casings at .the throat of the furnace, and back thence to the' discharge, a circulation of water being thussecured, keeping the pipes themselves and the furnace-throat comparatively c ool. Owing to the coolness of the pipes extending along the interior of the rotating vessel, aportion of the molten material solidifies on them, I incrusting them so as to form inwardly projecting longitudinal ribs,
which, as thevesscl rotates, cause the pasty mass to rollV and tumble over on itself, thereby facilitating and promoting the reducing and puddlin'g action. In order to. subdivide-the mass into portions, so as to form balls of convenient size, I make the pipes that extend along the interior'surface of the furnace-ch amber. with several bends or expansions projecting inward. The material incrustin g these from the general surface' of the lining, which, las the chamber rotates, have the effect of dividing the more or less viscid mass into separate lengths, each of which, by the rolling, be- \comes formed into a ball. The working-door ofthe furnaceoccupies a place in its front ont tudinal pipes. turned to such a position that the door is above the center, and the charge may be shot into the vessel from an elevated platform. When the balling is eected the rotating vessel is v'stopped in such a position that thedoor is under the center. 'The door is then opened cording to the nature of the product required. In the accompanying drawings, Figure 1 is vfurnace according to this invention. Y
A is an annular casin g surroundin g the throat, which casin gis connected, by means ofthe pipes B and branches b, with the rotating slide-valve pipes D, so that water-circulation is' maintained through the casing A and pipes B, as indicated by the arrows. In the interior of the furnace the pipes B- 4and their bends H form cinder'or moltenore, which has set thereon owing'l to the presence of water in them, and
under treatment to tumble over on itself and to'be subdivided into portions, thereby facilitating and' promoting the lreducing andpud- 4dling action by causing every part of the mass to be exposed to the intense heat of the flame into balls of convenient size fo`r handling. n v v Instead of one annular casing, A, several sepn arate casin gs may be employed,-each having cirlessnumber ofthe pipes B and of their bends.
Having thus described my invention, I claim bends 'or expansions forms mounds projecting a longitudinal section, Fig. 2 4is an end view, Y and Fig. 3 a transverse section, of a rotatlve vand the particles of metal to be agglomeratedl culating-pipes, and there might be a greater or of the center, clea'r of the trunnion, and also of 6o the branch pipes radiating from it to the lon gi- For charging the vessel it isV and the balls are withdrawn for treatment, acy' G, and through itwith the supply and discharge ,l

In a rotative furnace, internally projecting tubes, in combination with means for sup 5 plying the saine with iowing water, whereby said tubes are incrusted with molten material or cinder, forming ridges on the lining, substantially as described.
2. In a rotative furnace having internallyro projecting tubes, in combination with means for supplying` the same with flowing Water, the
bends or knees, whereby mounds are formed on the lining, substantial] y as and for the purposes described.
3. In a rotative furnace, the combination of 15 the tubes, kept filled with liowing Water and provided with bends or knees, with a Watercasing or water-casings at the throat,substan tially as described.
