! When firing clay ware of all kinds, it is necessary that at the right time the required heat level or the ember level is displayed to remove the fire and to close the kiln for what purpose the ember knife of the present invention serves. In the furnace becomes a crucible filled with a mixture of an enamel-like mass hung, a clay rod placed vertically on this melt and the whole thing exposed to the furnace fire in such a way that this clay rod, depending on its cross-section, height, Weight and degree of heat sink more or less into this melt during firing and this sinking in is made recognizable on the outside of the stove by means of a pointer mechanism and the like.

It is on the drawing:

Fig. Ι the vertical section through the ember knife inserted in an oven,.

2 shows the side view of the upper part of the same,

Fig. 3 of the Grundrifs of the pointer plate of Fig. Ι and 2,

4 shows the outline of the same plate by itself;

Figures 5 and 6 are front and side views with the device attached to a stand Pointer for the embers knife;

7 shows the cross section of an upright kiln with embers,

8 shows the cross section of a lying kiln with embers,

9 shows a view of a pointer disk visible at the front of the furnace.

The ember knife is used to burn pottery of all known types A scale with a pointer on the outside of the kiln shows when the glaze will be applied begins to melt and how the embers gradually increase inside the furnace. Further the same gives him the time when the fire will stop and the furnace will be closed without the need to take samples from the glowing furnace, and the like.

The ember knife is attached to a suitable place in the insert room of the furnace (Fig. 1, 7 and 8) and consists of a crucible A filled with molten mass, which is connected to the coupling tube B (made of highly refractory clay) and the clay spigot C through the ceiling D going pipe E is attached. On the molten mass, clay rods G going through the pipe E and the pipe F are placed on top of one another, which lead through the vaults to beyond the kiln and are connected to a scale and pointer (see below). The pipe E rests with a socket on the bottom of the protective pipe H, which is placed on top of the vault D with clay mortar and is walled into the upper vault. The pipe F for the clay rods sits down in the socket of the pipe E and closes with a flange from the protective tube H , which protects the pipe F against the train in the flame collector J, Fig. Ι and 7, in order to get for longer use stay. A sheet metal vessel K loaded with lead shot is placed on the uppermost clay rod G in order to exert a certain pressure on the melt mixture.

Claims (1)

The tube L carrying the pointer plate is placed on the protective tube H and ^{has a slot L 1} covering the third part of the circumference. A hemp cord is attached to the hook of the loading vessel K , which is laid over a roller N mounted on the bottom of the plate M and a roller N ¹ mounted on the outside and is loaded with a weight N- to keep the same tensioned. At the point where the cord lies (Fig. 2 and 4), a long slot in the plate M, on which a rack O is guided horizontally, with a downwardly standing clamp O ¹ , Fig. 2, is provided in which the hemp cord is clamped so that it transmits the movement of the clay rods G to the rack O , which by means of a toothed gear rotates the pointer of the scale, on which there is a degree of Celsius. The rack O is extended to the other side and a pointer P adjustably attached to it, whose arm P ¹ , which is extended to the rear, hits the lever P ² at a certain degree of heat, whereby a bell signal directed to a certain location is given to the burner on it to call attention to the fact that the furnace is to be shut down. The molten mass in crucible A will melt at a certain heat and, as the temperature rises, relatively lose its specific gravity, so that the temperature according to the clay rod G will sink deeply into the molten molten mass and this will be displayed on the scale above. In Figs. 5 and 6 another, simpler pointer is shown. A stand Q carrying the scale at the top is attached to the protective tube H , and an extension rod R guided in slots in the stand Q is placed on the uppermost clay rod G, which carries a metal container 5 for loading with lead shot and a double pointer at the top. . In the modification illustrated in Fig 9, "the movement of the verticale Thonstangen G with the seated on a horizontal shaft role T U V and a pointer is displayed on a side-mounted _Scala. When the ember knife is in the furnace for the first time, the burner has the furnace, as well as burning out and closing in the old, accustomed way, just as it was before Experience and characteristics. He will watch the scale on the side know when the glaze starts to melt. If the burner now remembers the number, at which the pointer was when the furnace was closed, it will be, provided that the If the fire turned out to be flawless, the furnace should always be shut down at this number. ; Paτεnt claim: A glowing knife (pyrometer), whose clay rods G, guided in the socket pipe E and conduit pipe F , sink more or less deep into the latter depending on the temperature to which the molten mass of the crucible A is exposed and transfer this movement to a pointer mechanism by means of suitable mechanisms to indicate the temperature . ; For this purpose ι sheet of drawings.
