page_text: New or Improved Device for Facilitating the Fixing, Adjustment,
and Removal of Electric Incandescent Lamps.
I, FREDRIC HAROLD COULSON, of 42 West Bank, Scarborough, in the County of
Yorkshire, do hereby declare the nature of this invention to be as follows:-
My invention has for its object a device wherewith electric incandescent lamps
may be fixed in position, adjusted, or removed without the aid of a ladder, or the like,
when said lamps are in an elevated position, or so situated as to be difficult of access.
This device I construct of a handle of the required length, formed, if preferred,
in two or more parts and fitted at one end with a holder formed of a number of
spring arms, so shaped and connected together, or to a common base-piece, that a
lamp placed between them will be held sufficiently firmly to permit of it being attached
to or detached from, or adjusted in the ordinary lamp holder by suitable manipulation
of the handle.
The arms forming the holder may be so connected together, or to the base, that
the distance between them, and consequently the size of the holder may be varied
to suit lamps of different sizes, whilst to permit of the device boing better manipulated,
the neck of the holder proper, or the top of the handle, is preferably constructed to
work on a movable joint.
When desired the arms of this spring holder may be paulded or otherwise prepared,
and the holder also fitted with spring or springs in the base to minimise the
possibility of the lamp being broken, as this is being fixed, adjusted, or detached,
whilst, to enable said arms to more firmly grip the lamp, auxiliary springs may be
employed, such as for instance, oue or more spring or elastic rings arranged to
encircle said arms.

1, FREDRIC HAROLD COULSON, No. 42 West Bank, Scarborough, in the County of
Yorkshire, Mechanic, 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 :-
My invention relates to a device, for the fixing, adjusting, or removal of electric
incandescent lamps should such lamps be situated in otherwise inaccessible positions.

page_text: The objects of my invention are
To provide a lamp adjuster 1st Simple in construction 2nd So constructed that
by suitable manipulation, electric incandescent lamps umy be fixed in position, adjusted
or removed, from the ordinary lamp holder, without direct handling of the lamp or
holder.
I attain these objects by the mechanism herein described and illustrated.
Fig. is the elevation of the lamp adjuster.
Fig. 2 is the section of the lamp adjuster.
The lamp adjuster is formed of a handle A. of the required length, and formed if
preferred of two or more lengths.
B. is a metal tube secured to end of A. by means of screw. Care suitable tempered
mictal arms, preferably, six in number, which are fastened inside B by the telescopic
bush, D, and screw E, and to which is attached in the manner shown a truncated
hollow cone of india-rubber, or other suitable material as at F.
The metal arms C. are preferable so shaped, to form an egg shaped cavity, in
combination, terminating at the top by a loop, through which passes the spiral
spring G.
Having now particularly described & ascertained the nature of my said inven-
tion, in what manner the same is to be perforined, I declare that what I
⚫claim is
1st. A lamp adjuster so constructed that it will by suitable manipulation, of the
handle, fix in position, adjust, or remove electric, incandescent lamps without direct
handling of same.
2nd. The construction of the spring arms-in combination with the india-rubber,
or other flexible fabric as herein described.
Br. The manner herein described of incircling spring arms by a spiral spring.
Dated this 1st day of December 1896.
