necessary with the muffle-furnaces of Fürbringer's construction, being in plan of
U-form.
For the transport of the material to be heated in such furnaces, small carriages
running on rails have hitherto been used. But it has been found very incon-
venient to direct the movement inside of the furnace which as is well known is
In order to attain an easy transport of the material to be heated in every
direction inside of the muffle-furnace the floor of the muffle is covered with balls
upon which rest plates for carrying the material to be heated. These plates can
easily be pushed in every direction on the balls. The floor of the muffle has,
suitable for the purpose, a well turned up eage at the entrance, the purpose of which
is to prevent the balls in the furnace from falling out. On drawing the plates out
of the furnace a part of the transport-balls are drawn out at the same time.
These fall into a gutter which is situated before the exit of the muffle, and roll
into a receptacle, out of which they are again thrown into the entrance of the
muffle in order to serve anew as means of transport for the plates.

Improvements in Muffle and Similar Furnaces.
I, JOHANN FERBRINGER, of Schirnding, Bavaria, Germany, Ceramic Engineer,
do hereby declare the nature of this invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement:-
This invention is a contrivance for the transport of the material to be fired in
such furnaces, especially in muffle furnaces. For the transport of the goods to
be fired in such furnaces, small carriages running on rails have hitherto been used.
But it has been found very inconvenient to direct the movement inside of the
furnace which, as is well known, is necessary in the case of the muffle furnaces
of Fürbringers construction, being in plan of U-form. In the accompanying
drawing I have illustrated my invention. Like characters designate like parts.

page_text: Fig. 1 represents a vertical and longitudinal section of a draught muffle furnace
with the new transport contrivance. Fig. 2 is a horizontal and longitudinal section
of same. Fig. 3 shows a sectional view of the arrangement for catching the
transport balls at the outlet. Fig. 4 is a sectional view of the front part of the
muffle.
In order to insure an easy moving about of the goods to be fired in every
direction within the muffle furnace a, the flooring of the latter is covered with
balls b, upon which are placed the trays or plates c, carrying the goods. The
flooring of the muffle is preferably tilted upward at the front end f, thereby pre-
venting the balls from falling out again. In taking out the trays c, a number
of the balls b will roll out and drop into the trough d and from there into the
receptacle e. From here they are removed by hand and introduced again in the
front part of the furnace.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is :-
1. A contrivance for moving about the goods to be fired within a muffle furnace
consisting of a number of balls b on the flooring of said muffle furnace, upon which
rest the trays or plates c carrying the goods to be fired, as described.
2. In combination with a transport contrivance the trough d and the receptacle c
at the outlet of the furnace for catching the balls, as set forth.
3. In a transport contrivance, the use of a preferably tilted upward front end
of the flooring, as and for the purpose specified.
