PROVISIONAL SPECIFICATION.
Improvements in Safety Devices for Lamps for Burning Paraffin or
similar Oils or Liquids.
I JAMES JOHN GRANT of 71 St. George's Road Southwark in the County of
London, Lamp Manufacturer do hereby declare the nature of this invention to be
as follows:-
The object of my invention is to provide for lamps burning paraffin benzoline
or light volatile oils a device or apparatus for ensuring safety while burning or in
case the lamp is overturned or upset. Outside the ordinary wick-holder I provide
a sliding tube with a slot upon one or both sides having a stud or pin to control the
upward motion of the sliding tube. The purpose of this pin which is fixed upon
the wick-holder. proper is to prevent the outer sliding tube from being detached.
Upon upsetting or turning the lamp over from the upright position the outer wick
tube falls or moves so as to extinguish the light. I further provide in such lamps
a small valve for the escape of gas evolved in the reservoir during the combustion
of the oil. This valve is in the shape of a small tube indented on one side and
containing a ball which is not allowed to pass the indented position which will
remain normal at the under side of the perforated escape valve. As the lamp is
tilted or overturned the ball falls into position closing the valve and prevents any
inflammable cases from escaping, thus ensuring safety. This valve is preferably
fixed in the screw stopper ordinarily used for filling the reservoir.
Dated this 22nd day of February 1896.

Improvements in Safety Devices for Lamps for Burning Paraffin or
similar Oils or Liquids.
I JAMES JOHN GRANT of 71 St. George's Road, Southwark, in the County of
London, Lamp Manufacturer 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:-
The object of my invention is to provide for lamps burning paraffin, benzoline
or light volatile oils, a device or apparatus for ensuring safety while burning or in
case the lamp is upset or overturned. Outside the ordinary wick holder shown at
Fig. 1, for flat or round wicks I provide a sliding tube with a slot c upon one or
both sides I provide also a stud or pin d. d. to check or control the upward motion
of the sliding tube. The purpose of this pin which is fixed upon the wick holder
proper is to prevent the outer sliding tube from being detached. Upon upsetting
or turning the lamp over from the upright position the outer wick tube falls or

page_text: moves so as to extinguish the light. I further provide in such lamps a small valve
for the escape of gases evolved in the reservoir during the combustion of the oil.
This valve which is shewn at B. Fig. 2. is in the shape of a small tube indented on
one side and containing a ball D. which is not allowed to pass the indented position
as shewn at C. but will remain normal at the under side of the perforated escape
valve B. As the lamp is tilted or overturned the ball falls into position closing
the valve and preventing any inflammable gases from escaping, thus ensuring
safety. This valve is preferably fixed in the screw stopper ordinarily used for
filling the reservoir.
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. A wick holder, with outer tube, slot, and stop, for the purposes described and
illustrated substantially and as set forth.
2. A valve with ball, for the purposes described and illustrated substantially, and
as set forth.
Dated this 21st day of November 1896.
