Improvements in Blow Lamps.
I, HARRY WILSON of 137 Ombersley Road in the City of Birmingham,
Pattern Maker, do hereby declare the nature of this invention to be as
follows:-
:-
I construct the lamp in the following manner.
use a container or reservoir carrying the spirit and cotton into which container
passes a tube forming the generating chamber for the vapour and from the side of
this tube extends a smaller tube closed at its extreme end and passing along the
outer surface of the taper tube which covers the burner. This taper tube is made
removable so as to facilitate cleaning.
A clip or connecting piece is placed over the taper tube and the smaller tube,
for the purpose of conveying the heat to the latter and assisting in the generation
of vapour.
At the head of the generating chamber is a valve to regulate the flow of vapour
to the nipple. The base piece of this valve extends downward into the generating
chamber and is so formed that the vapour rising between it and the sides of the
chamber will reach two converging channels cut in this base piece, preferably in a
downward direction which two converging channels meet a channel taking an
upward direction to the seat of the valve. The upper piece of the valve being cut
with a channel to receive the nipple in the ordinary way.
In connection with the valve is a plug and key a half turn of which will entirely
open or close the valve.
Around the cup for starting the lamp, I form a sinking or channel to receive any
overflow of the spirit thereby avoiding accidental firing. Instead of using the
ordinary cork or packing for the feeder screw cap, I may use a screw cap with
central metal plug.

cleaning the nipple e, which nipple e is screwed into the outer end of the channel f.
At the head of the generating chamber ba valvo is formed in the channel g to
regulate the flow of the vapour to the nipple e. The valve is regulated by a plug h
having a screw thread ; working in a seating k so that a half turn of the lever arm
or key i attached to its top will cause it to entirely open or close the valve.
At the head of the valve is a chamber having in it a recess t formed to give
the vapour greater freedom when the valve is open, and from this chamber
extends the before named channelf to the nipple e.
Thus when the valve is open the vapour will rise into the chamber and pass up
the channel to the nipple e. From the side of the generating tube 6 extends a
metal rod m preferably tubular passing along near to the outer surface of the
burner tube c and having sliding upon it the clip n which is a bracket piece on the
wind guard o.
The sliding of this bracket n on the rod m adjusts the position of
the wind guard o at will, and turning the the screw pin p will hold it firmly in
position. This bar or tube m also serves as a conductor of the heat to the
generating tube beneath the valve as at g.
The top r of the container or reservoir is sunk or dished round the starting cup &
so as to prevent any of the spirit which may overflow from running down the sides
of the container a.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In soldering or blow pipe lamps the connecting of the burner and also of the
nipple to the valve portion as herein described and illustrated.
2. In soldering or blow pipe lamps the upright portion of the valve and the plug
actuated by a lever arm or key.
3. In soldering or blow pipe lamps a rod or tube for the purpose of conducting
the heat from the flame tube to the generating tube, which rod or tube may or may
not be used as a support for the wind guard of the flame tube.
4. Forming the top of the container or reservoir of soldering or blow pipe lamps
dished or sunk round the starting cup for the purpose herein set forth.
5. Constructing soldering or blow pipe lamps with valve recess in chamber,
nipple, and regulating lever all substantially in position and formation as herein
set forth and described.
