COMPLETE SPECIFICATION.
Improvements in or relating to Incandescent Electric Lighting.
I JOHN HARTNESS, of East Boldon, in the county of Durham, Engineer, 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 this invention is to localize the electric light by attaching it to some
convenient part of the body of man or beast thereby securing portability and bringing
the light as near the work in hand as may be desired.
The invention is designed more especially for the use of operatives having work in
hand necessitating very close and accurate inspection or manipulation, such for
example as the examination of the links of chains, chain cables, anchors, plates, fine
work or any other such objects or purposes.
The method of carrying the invention into effect is as follows :-
I place and fix in suitable position and in the usual manner a main wire which
leads direct from an electric generator and I take therefrom branch wires and connect
them to a lamp or lamps fixed to the dress, head-gear or other part of the user and
in the most suitable position or positions for the specific purpose the said branch
wires having sufficient slack to allow them to move freely following the movements of
the user.
1 have illustrated such an arrangement in the annexed figures which show a glow
lamp a of any suitable type and candle power affixed by a swivel or it may be an
universal joint connection b to a plate c. This plate may be of any suitable form
having a pin or clamp or other device for fixture; it is shown secured to the cap or
head-gear of the operative just above the eyes, a peark intervening of sufficient
length to shade the eyes yet not to interfere with the rays of light: are the branch
wires leading to the main lead which is not shown but being fixed in any convenient
place.
The lamp or lamps may be fixed to any part of the dress or person of the operative
best adapted to his particular work as for example the wrist when required or both
cap and wrist.

as and for the purposes hereinabove set forth.
