JOHN IGNATIUS BOLTON, 24A, Bramshill Gardens, Dartinouth Park, London, N.W.
Electrical Engineer, do hereby declare the nature of this invention to be as follows:-
With reference to the accompanying drawing I take an ordinary incandescent
glow lamp bulb of any shape A. I then insert into the bulb a reflector B,
this reflector may be moulded with and form one piece with the outside bulb,
it may be of any size shape or form, and may be composed of any suitable
substance, and of any colour, I by preference make the reflector of plain fluted
glass, which I afterwards silver on the inside, or I mould the reflector in white opal
glass, the reflector may be moulded or cut in any possible way for the purpose of
reflecting the light. C is an ordinary glow lamp filiment, the ends passing through
the sides of the reflector, and then out of the top of the bulb, the filiment may be of
any shape and fitted into the bulb in any convenient way. The lamp is finished off
for use in the usual known way. The improvement I claim for this my invention,
which is the placing of a reflector inside the bulb of an incandescent electric glow
lamp as discribed, is by so placing the reflector the light is reflected in every possible
direction at the same time, the reflector greatly increasing the power of the light
also.

An Improved Electric Incandescent Lamp.
I, JOHN IGNATIUS BOLTON, 24A, Bramshill Gardens, Dartmouth Park Hill
London, N.W., Electrical 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:-
Which is a combination of a carbon filament within a receiver made entirely of
glass, into which wires pass and into which is inserted a reflector made of glass
silvered, or white opal with hooks or eyes of glass or wire attached for supporting the
filament or filaments and from which receiver air is exhausted. The reflector only
with or without hooks or eyes being my invention I take the reflector B Fig. 2
which is a hollow piece of glass, which is blown in any known way to any design or
shape required, by preference as drawn, which is silvered on the inside by the most
approved known way, which has wire or glass hooks or eyes attached Ď Fig. 2 for
supporting the filament or filaments, the filaments C passing through the said hooks
or eyes which are attached to the reflector by any approved known method, as shown
....01

page_text: at Fig. 3, the reflector may be used with or without the hooks or eyes for supporting
the filaments, the reflector may be composed of any suitable material by preference I
use glass as discribed, the silvering if required being covered by a deposit of copper
by the present known method, or I use a reflector inade of white opal glass, having
fixed the filament or filaments in position as shown at C Fig. 3. I then insert the
combined reflector & filament into the glass receiver A Fig. 1 through the top,
the top of the receiver is then closed, at which time the glass top of the reflector B is
fused with the glass forming the top of the receiver A, as shown at Fig. 4, by this
means the reflector is held firmly in its position within the receiver, thus the top of
the receiver A is closed, the reflector B fixed in its position, and the leading in
wires E E sealed in position at one and the same opperation as shown at Fig. 4 the
doing of which may be by any known approved way, the receiver is then exhausted
of air in the known way, small holes may be made in the top of the reflector B so
that any air that may be in the reflector may be exhausted from the same at the time
the air is being exhausted from the receiver, A, Fig. 4 shows a lamp complete. A
is the receiver, B the reflector, D D D the hooks, and C the filament and leading
in wires.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim as my invention is :-
1. The reflector and the placing of the same within the receiver of an incandescent
electric lamp.
2. The reflector on which hooks or eyes are attached for the support of a filament
or filaments, and holding apart the filaments when more than one are contained in
one receiver.
3. The hollow glass reflector silvered on the inside or the outside or made of white
opal glass.
