COMPLETE SPECIFICATION.
Improved Device for Burning Down the Nets of Incandescent
Gas Lamps.
I, GUSTAV OLLENDORFF, Manufacturer of 20 Neue Tauenzienstrasse, Breslau,
Germany, do hereby declare the nature of my invention and in what manner the
same is performed to be particularly described and ascertained in and by the
following statement :-
The present invention consists of a device for burning down the impregnated
nets which form the incandescent bodies in incandescent gas lighting, and the
device is designed to enable anyone to burn down the nets for his own use without
any danger of shaking and destroying the same.
And in order to render the present Specification more easily intelligible
reference is had to the accompanying drawing in which similar letters of reference
denote similar parts throughout the several views:―
Fig. 1 being a perspective view of the apparatus,
Fig. 2 a similar view with the cone upon which the nets are formed removed and
the net suspended previous to being burned down,
Fig. 3 a side elevation of the burner crown and net burnt down and suspended
thereon and
Fig. 4 a vertical section through a Bunsen burner employed to burn down
the net.
The device consists of the base plate c having suitable pins d upon which are
placed the cone 6 for forming the net previously to burning it down, the standard e
having at the top a horizontal fork k hinged thereto and capable of being thrown
upwardly, and the burner crown fon to which the net is placed after it has been
burned down. Instead of providing pins in the base plate c the cone and stand
may be provided with such pins which may be adapted to fit into holes in the
base plate.
The nets are burned down in the following manner :-
The net a is first formed on the cone 6 by wiping the same over the said cone
with the hands. In cases where a double chimney or glass cylinder is used as
shown at Figure 2 the sleeve, which connects the two parts of the cylinders and
simultaneously serves to support the net in the same, is now placed on the
bifurcated ends of the fork k as shown at Figures 1 and 2 and the hook h of the
same is inserted into the top i of the net, said net being thus raised slightly from
the cone (Fig. 2). The cone is now removed and the net is in position for being
burned down, which may be accomplished by means of a Bunsen burner such as
shown in section at Figure 4. The sleeve g together with the incandescent net
attached thereto is now removed from the fork k and placed in the cylinder as
shown at Figure 2 and the upper part of the cylinder then fixed in the
said sleeve.
If a cylinder is employed consisting of one part only, the net a is hung on one of
the hooks mm detachably mounted on the bifurcated ends of the fork k.
The net is then burned down and finally removed together with the hook m and
fixed to the top of the rod mounted in the burner crown and serving to support the
same as shown at Figure 3.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is performed I declare that what I
claim is :-
The combination of a base plate having detachably mounted thereon a cone, a
standard e having hinged at the top a horizontal fork k, and detachable hooks at
the bifurcated ends of the said fork substantially as described and shown.
