Application filed .TanuaryIG, 1911. Serial No. 603,001.
.'Be it known that we, Vrcron Porr and.
Anonrnn Minna", both of Paris, France, have inyented a new and useful Improvement in Continuously-Operating High-Temperature ResistanceFurnaces, which improvement is fiil'ly' set forth in the following specification. The present invention relates to improvements in resistance furnaces. These improvements will be readily understood from the following description and by reference to the accompanying drawing, in which:
Figure 1 is a vertical section, and, Fig. 2
horizontal section "of" one constructional form of the improved furnace. Fig. 3 is a verticalsection, and Fig. 4 a horizontal section'of a second embodiment of the invention." Fig. dis a vertical'section of a furnace"with'three tanks. The outer wall of the furnace A is of refractory material such as magnesia, alumina, bauxitesor refractory earths of any kind. Inside this wall is arranged the rcsister 13,13 constituted by agranular mass kept apart from the tank I) by a protecting or distance plate C (Figs.- 1 and 2). The plates C, which-may be either continuous or perforated, may also be conductors or insulators. When they are conductors, their electrical resistance may either be less than, equal to or greater than the resistance of the resister B, 13 ;'they then serve as a secondary resister. hen the plates C are conductors, they are preferably formed of carborundum. When they are insulators they may advantageously be formed of bauxite, alumina, or magnesia, that is to say of refractory oxids. The tank I) may be a conductor or not and in contact with the protecting place G or separated therefrom.
In the furnace,represented in Figs. 1 and 2, the resistor touches the walls and surrounds the plates (J throughout their entire surface.
In the modification illustrated in Figs. 3 and 4, the resister B only heats the tank I) laterally and the two branches of the resister can be connected either in parallel or in series. In addition, the resistor is kept separated from the wall A of the furnace by a second protecting plate C. The current is conducted into these two apparatus by electrodes E.
tanks illustrated in Fig. 5, the central tank I) does not contact either with the resister or with thebottom of the furnace. Similarly, the register B does not touch the walls A and the protecting plates C C from flues which touch neither, the bottom of the furnace, the tank,'nor the walls of the furnace, in such a manner that the interior of the furnace can be repaired without touching either the bottom or the walls, which will serve for an indefinite period.
hat we claim and desire to secure by Letters Patent of the United States is 1. In a high temperature resistance furnace, the combination with the outer wall of the furnace forming a furnace chamber; a tank in said chamber; a resistor of granular material in said chamber; a protecting wall or plate interposed between said tank and resister; and a protecting wall interposed between said resister and the wall of the furnace chamber.
2. In a high temperatitlre resistance furnace, the combination with the outer wall of the furnace forming a furnace chamber; a tank in said chamber; a resistor of granular material in said chamber; and a prote ting wall or plate interposed between said tank and resistor, said protecting wall being of electrically conductingmaterial containing carbon. I 3. In a 'high temperature resistance furnace, the combination with the outer wall of the furnace forming a furnace chamber, a tank in said chamber; a resistor of granular material in said chamber; a protecting wall or plate interposed between said tank and resist-er; and a protecting wall interposed between said resistor and the wall of the furnace chamber, said protecting walls being of 'carborundum.
In' witness whereof we have vhereunto signed our names this 28th day of December 1910, in the presence of two subscribing wit- HQ-SSGS.
