'o allwitomitmy'concern:. I
MAURICE AU- .siding at 3 Rue de la Ferme,
invented certain new and'iiuseful Improvements' in Furnaces; and; I do hereby-declare the following tofbe. a full, clear, andexact description of theiinvention, enable others skilled in ence being had to the accompanyingidrawings, and to the letters or figures of reference specification.
This inventionrelates to improvements in furnaces, more specifically to rotating and other furnaces comprising'two parts which are adapted to move relatively to each other f on the path of the flame or hot gases. V
In such apparatus the junction between the two parts of the furnace requires to be made in such a manner that the losses of heat are as small as possible or so that the fall of temperature is a predetermined quantity solid materials more are carrled along do and moreover that the not bind the two parts of the furnace'together, which would interfere with their necessary relative motion. 7 v This invention fulfils the conditions while procuring other advantages as will be hereafter explained. Several modes of applying the invention are shown on the accompanying drawing.
Figure 1 of this'drawing is a longitudinal section of the two parts of a furnace which are adapted to move relatively to each other. Figs. 2, 3 and 4 are similar views representing different modifications.
Fig. 5 is a view inlongitudinalsection of furnace with my invention applied a tilting thereto.
In all cases the ing a free interval and b of the furnace tively to each other, the surrounding air alone forming an air 'oint owing to the fact that it is not carried invention consists in leavalong with the flame or is carried along only to a certain extent which is determined by the structure ofthe above mentioned parts.

the" opening 'fcZ *is made "more or {less conic'agl .112 more air ist o be carried into 5, because performed there, then the opening'd is made thanto c, as shown icy-Fig.3.
Or else, for the same purpose the openings 0 and pl may have the same diameteron most of their lengths straight but it is given a largerdiameter but the outer portion ofthe i as shownby Fig. 4.
It will be easily.understoodthat-ina furnacemade according to this invention the losses of heat will really be'suchfas predetermined by the structure. male more or lessmelted that are carried along, they will fall down by themselves or. Wlll be removed by the attendanti at the gap between the parts a and b ,-there for there will .be' no risk of these parts adhering to each other and interfered with. v
In Fig. 5, 4 is atilting furnace, B the charging door, C the discharge orificeand heir relative motion 1 being D the fuel-valve controlling the admission of 7 fuel, as tar, from the fuelheating coil Gr.v
The furnaee'is mounted on a frame E so as to tilt while keeping the'ports (Land?) in alinement, the port I) conducting the gases vto the chamber F connected to astack, as is customary. The coil forheati'ng the fuel is contained in'the chamber F and is heated by the gases leaving the. furnace.
In addition to the advantages above men- V to see, on the way 7 how the industrial f tioned the device permits of the flame or hot gases,

Moreover, the device gives the two parts separated from each of the furnace every liberty of expanding While otherwise such expansion might prevent their relative motion.
Finally, the keeping of a furnace 1n good order is made very easy by this invention as v V the latter does away with anysealing mate;

A metallurgical furnacehaving a rotatable gas portforl the passage of gas and a statlonary port, said ports of different efiecand sepative diameters being in alinement rated from eone another'byan open space visibleunder all conditions ofoperation and stationary gas port and i said port, the port from flame, under all, conditions ofoperation and surrounded by air, the gas current fromone port to the other being suflici'ent to maintain the as my invention I have signed surrounded by air, thegas current from one port across said space to the other port of the furnace beingsuflicient to prevent diversion of gas through said space.
