page_text: A Combined Extinguisher and Trimmer for Paramn Lamps.
We, WILLIAM GEORGE ACKERMAN, and GEORGE HENBY BEST, both of West Street,
Bridport, Dorset, Musical instrument sellers, 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 our invention relates to a certain new and useful improvement in burners for
parafin lamps, and which invention has for its object to provide a simple and efficacious
appliance by means of which the flame of parafin lamps may be readily and con-
veniently extinguished, without the necessity of blowing into the chimney of said lamps,
-a practise which has heretofore proved dangerous.
A further object of this our invention is to provide an automatic and ready means
of trimming the wick of said lamps when extinguishing the flame, thus rendering the
wick ready for relighting.
Our invention may be described as follows:-reference being had to the accompanying
drawings and the figures and letters marked thereon,-similar letters of reference
indicating corresponding parts throughout.
Fig. I is a part sectional elevation of an ordinary lamp burner, shewing the appli-
cation of our invention.
Fig. 2 is a sectional plan view on the line of Fig. 1.
Our improvement consists essentially of a piece of flat metal A, one end of which
is made smaller than the main portion of the metal, and is suitably journalled in the
body of the lamp burner as shown at B. B'. At B', the piece of metal A is carried
through for a sufficient distance and provided with a thumb and finger disc, C which
is preferably milled and made of an oval form to distinguish it from the disc D, which
is used for raising or lowering the wick.
The aforesaid piece of flat metal A is bent so as to form a bridge E, which, when
the flame is to be extinguished and the wick trintmed, is caused to describe a radius
over the wick, by turning the disc C to right or left, thus trimming the wick by cutting
off the burnt portion.
The dotted lines in Fig. 2. shew the extinguisher as it rests when the wick is
alight.
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
1st. The extinguisher and trimmer A bent so as to form the bridge E, said
extinguisher and trimmer suitably journalled in the body of the lamp burner, and
provided with a suitable thumb-and-finger disc C, substantially as and for the purposes
hereinbefore described and illustrated in the drawings hereunto annexed.
2nd. The construction and general arrangement of my said invention substantially
as and for the purposes hereinbefore described and illustrated in the drawings
hereunto annexed.
Dated this 19th day of November 1887.
