An Improvement in Acetylene Lamps.
FREDERICK WILLIAM BARRATT, Ironmonger and Engineer, High Street,
Wimborne, Dorset, do hereby declare the nature of this invention to be as
follows:-
-
My invention relates especially to the formation of containers for the supply
of water to the carbide chamber of acetylene lamps, lanterns, and the like
especially those for household purposes and where immunity from smell is impor-
tant. I form a double or two seperate water chambers preferably one above
the other I fit the lower container with suitable screw or other attachment
for fixing to the carbide chamber and an arrangement suitable for the percolation
of water through to the carbide. I then fit a tube passing down from the bottom
of upper chamber and preferably through the lower chamber and bent or syphoned
up into the bottom of the lower chamber. Water filling screws are fitted and
a small open air hole or pipe is fixed in the top of upper chamber. By this
arrangement in the event of gas escaping upwards through the valve in lower
water chamber the gas is received or trapped in the top of the lower water
chamber and cannot pass outwards. The water from upper chamber passes
down through the syphoned pipe replacing the water as used from the lower
chamber or container.
Dated this Sixth day of February 1899.

manner the same is to be performed, to be particularly described and ascertained
in and by the following statement: —

air hole or pipe is fixed in the top of upper chamber. By this arrangement
in the event of gas escaping upwards through the water valve in lower chamber
the gas is received or trapped in the top of the lower container and cannot pass
outwards. The water from the top chamber passes down through the syphoned
pipe replacing the water as used from the lower chamber. The gas supply pipe
from carbide chamber may be carried up through both water chambers to burner
or otherwise
The accompanying drawing is submitted as an example only of the principle
as applied for fitting to the carbide chamber of a table lamp. A represents the
upper section of water container. 13 is the lower section or chamber. C is
the supply pipe from the upper to the lower container. I) is the water filling
screw with air inlet hole in the centre. E shows a small tube with screw cap
passing from the crown of lower container to admit of air passing out whilst
being filled with water. F F represents one method of screw fixing to carbide
chamber. G illustrates a method for percolation of water to carbide but is not
claimed in this specification.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declaie what
I claim is:-
A double water supply chamber for acetylene lamps as substantially described
in the foregoing specification
