IMPROVEMENTS IN APPARATUS FOR LIGHTING STREET-LAMPS
Year: 1884

page_text: JOHN BROWN, Gas Engineer 39 Charlotte Street Blackfriars, Surrey S.E. do
hereby declare the nature of my invention for IMPROVEMENTS IN APPARATUS FOR
LIGHTING STREET-LAMPS to be as follows :—
1st in order to facilitate the process of cleansing the apparatus (ordinarily
known as a Lamp-lighters torch ") from deposits of soot &c I connect the inner
shield thereof to the upper part of the case by means of a milled head screw
fitting into the outside case, so that by simply unscrewing the same, the inner
shield is removed with it and readily cleaned-2ndly instead of connecting the
lower parts of the torch together by means of an ordinary bayonet catch, and of
connecting the torch itself to the ferrule of stick or pole in the same manner,
I use a horizontal slot into which the catch pin works, the said pin working up to
the slot through a raised groove on the outer part of the case, leaving the extreme
or lower end uncut thus considerably stronthening the same.

JOHN BROWN Gas Engineer 39 Charlotte Street Blackfriars, S.E. do hereby
declare the nature of my invention for IMPROVEMENTS IN APPARATUS FOR
LIGHTING STREET LAMPS and in what manner the same is to be performed, to bo
particularly described and ascertained in and by the following statement :-
The object of my invention in the construction of Lamp-lighter's torches is,
First, whereby the necessary process of cleaning the torch from deposits of soot,
caused by the burning wick, is greatly facilitated Second, whereby the connection
between the moveable parts of the torch itself and its connection, with the ferrule
of stick or pole, are considerably 'strengthened.
Figures 1, 2, 3, and 4 of the annexed-drawings, together with the following
explanation thereof, will explain in detail the manner in which the construction-is-
to be performed-Fig 1 shows the inner shield of 'torch-Fig 2 the outer case-of
torch Fig 3, the lamp and ferrule of same and figure 4 the complete apparatus as
constructed according to my invention-Thus I connect the inner shield A Fig
(being-tho-part of torch upon which the soot collects) to the upper part of the
outer case A Fig 2 by means of a inoveable cap-O-Fig-1,-which fits into the outer
case A Fig 2, by means of a thread screw, thus forming a millod head screw cap,
which can, together with the inner shield be readily removed as often as required
for the purpose of cleaning or-any-other-object..
Secondly with a view of making a connection between the upper part-or-parts-
of the torch, and also between the torch itself and the ferrule or cap of stick or
pole, in such a manner that the connection is readily made and secured; instead of
using the ordinary "bayonet catch" which leaves an open cut on the edge of the
metal end, I use a horizontal slot B, B, B Figs 2, 3, 4, into which the catch-
pin B Fig 3 works, the said pin working up to the slot through a raised groove
(shewn in Figs 2, 3, 4 by the dotted lines) on the outer part of the case, thus
leaving the lower and extreme end of the case uncut, which has the effect of
considerably strengthening the parts, and minimising their liability to get out of
order.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
First. In apparatus for Lighting Street lamps, ordinarily known as "Lamp-
lighter's torches," the combination of parts substantially as described, and shewn
in the annexed drawings.
Second. The method of connecting the parts of torch, and the torch itself, to
the ferrule of stick or pole, as shewn in Figs 2, 3 and 4 of the annexed drawings.
Dated this 22nd day of May 1885.
