We FRITZ VON KREMPELHUBER, of Amalienstrasse 11, Chemist and Josef,
KNIGHT OF SCHMAEDEL of Wittelsbacher pl. 13 Architect both of Munich in the
Empire of Germany do hereby declare the nature of this invention to be as
follows:
This invention consists in a blow-pipe lamp suitable for deflecting and concen-
trating a flame upon a point for heating or burning, for instance for soldering or
branding or other purposes where an intense localized heat is required. The
improved lamp consists of a receiver to hold spirit or other combustible liquid
having a wick tube with wick therein and an air blast tube directed in such a
manner as to deflect the flame from the wick towards the point of a bent wire
attached to the receiver and provided with a movable block or screen to concentrate
and guard the point of the flame.
The wick tube carries a disc to guard the receiver from the flame.
In place of burning liquid such as spirit, gas or candles or tapers may be used to
give the requisite flame, the parts being modified in accordance therewith.
The air may be supplied to the blast pipe by a suitable bellows or by blowing
with the mouth into a tube attached to said blast pipe.
