Improvements in and relating to Torches.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 4 Southampton Buildings, in the County of Middlesex, 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:-
My invention relates to a receptacle for holding an absorbent material charged
with a light producing compound and consists in a peculiar arrangement of parts
by means of which air is introduced into the body of the material and also centrally
into the field of combustion.
The object being to produce a torch particularly adapted to burn highly
inflammable fluids that require a free and abundant supply of air.
This object I attain by means illustrated in the accompanying drawing, in which
Figure 1 is an elevation showing my torch complete.
Figure 2 is a vertical section of the same.
The receptacle A is preferably made of cast metal although wirework would do
equally well, or it may be of sheet metal properly perforated and mounted. The
body part of the receptacle A is supported by a hollow neck D which is adapted
to be screwed into a socket piece C which may be attached to a pole, rod, or
handle as may be desired. An air supply tube E extends from the neck D to the
top of the receptacle A passing to the cover B which is perforated.
supply tube E is perforated as indicated at F... F (Figure 2) so that air is
admitted to the absorbent material S with which the receptacle is filled.
The air
The holes H... H in the socket piece C admit air to the tube E and through it to
the auxiliary tube K. The object of the tube K is to take air from the supply
tube E and deliver it into the centre of the flames produced by the other parts of
the torch.
To use my invention, the cap B is removed from the part A which is filled with
some absorbent material like asbestos: this material should be packed evenly and
not too solid so that air may circulate in it and become charged with the vapor
arising from the fluid used and thus constitute an inflammable mixture.
After the receptacle is filled, the cap B may be replaced and the constituents
saturated with the fluid to be used and the torch ready for use.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
In a torch, a perforated receptacle adapted to hold an absorbent material, an air
supply tube penetrating the said absorbent material and adapted to supply air to
the same, and an auxiliary air tube adapted to supply air to the central part of the
flame, substantially as and for the purpose set forth.
Dated this 12th day of March 1895.
