page_text: EDWIN HARRISON Engineering Agent of 15 Wakefield Street London W.C. in
the County of Middlesex, and THOMAS CHILTON Tobacconist of 46 Compton
Street, Brunswick Square W.C. in the same County, 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 :-
This invention consists in the manufacture and employment of an appliance for
extinguishing the light mechanically instead of blowing it out and thereby
removing the liability to explosions induced by the process generally adopted, it
also provides that in the event of the lamp being overturned, the extinguishing
appliance at once becomes self-acting and the flame is instantly quenched, thus
preventing the possibility of fires arising from such accidents, the appliance consists
of an outside tube or movable jacket as shewn in accompanying sheet of drawings,
see letter B, Figures, 1, 2 and 3, of exactly the same form as the wick tube or wick
holder, A, around the exterior of which it works longitudinally, covering the wick
holder from above the flat dome F, in Figures 1 and 3, to the top of the tube A,
Figures 1, 2, and 3-fixed upon the jacket B as shewn in Figures 1, 2 and 3, is a
lugged plate D, with eyes in each projecting lug through which is fitted a pin and
to the centre of which is fitted and suspended a short strong wire rod, E Figures 1
and 3, slightly curved, extending downwards protruding to the required extent
through one of the lower openings for ventilation in the exterior immediately
above the rim of the flat dome, F, Figures 1 and 3,-in such a manner as to permit
of the free and easy movement upwards and downwards of the wire rod, E, which
communicates the upward motion to the sliding jacket or extinguisher B, Figs. 1, 2
and 3, from which it is suspended by the pin fitted through the eyes in lugs of
plate, D, as shewn in figures-to the end of the wire rod E, is fitted a small metal
ball or finger button the pressing of which imparts the upward sliding motion to
the extinguisher or jacket B, for extinguishing the light, which occurs immediately
the top of the jacket passes through the lips of the burner, C, Fig. 1-the extent of
the upward motion being fixed and limited by the position of the lugged plate D
on the extinguisher-after which it falls back by the force of its own weight into
position upon the dome, F, Figures 1 and 3, upon which it rests, and should the
lamp be overturned the sliding jacket B, at once moves forward through the lips of
the burner, C, Fig. 1, and instantly extinguishes the flame-When this appliance

page_text: is fitted to benzoline or spirit lamps with round wick tubes the projecting and
pendant finger wire for imparting upward motion for putting out the light, is
securely fixed upon the movable tube and work in one piece when extinguishing
the light, by slight upward pressure with the finger, and should the lamp be upset
the tube or jacket at once moves forward by its own weight and puts out the
flame-the extinguishing jacket is attached to the small chain usually a part of the
fittings upon these kind of lamps, thus the extinguisher cannt fall off under such
circumstances.
By this simple, cheap and effective method of extinguishing lighted lamps, in.
order to meet a much needed want the appliance can be made and fitted to all
sizes and kinds of existing lamps at a very small fractional cost upon the value of
each lamp, and obviate the expense of buying new lamps fitted with extinguishers.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is;
Novelty in the manner of applying the sliding jacket as an extinguisher for
lamps, mechanically and automatically putting out the light from underneath the
flame as described and particularized above and shown in the accompanying sheet
of drawings.
