Improvements in Candle Lamps.
I, HERBERT AUGUSTUS BENHAM of 40 Chandos Street, Charing Cross in the county
of Middlesex, General Metal Worker, do hereby declare the nature of said invention
to be as follows:-
The invention relates more particularly to that class of candle lamps known as
Reflecting reading lamps" but is also applicable to other forms of candle lamps.
Heretofore candle lamps have been made of fixed lengths which is sometimes incon-
venient to the user as he is unable to vary the height of the light to suit the purpose
to which he desires for the time being to apply the lamp, except by placing it upon
some independent article, according to my invention I remedy this inconvenience by
making the main portion of the lamp telescopic, that is to say by making the candle
tube capable of sliding up and down in a fixed tube carried by the base of the lamp.
In order to prevent injury by scratching to the exterior of the candle tube and at the
same time obtain a sufficiently firm fit between the two tubes I form the lower end of the
candle tube with circumferential rings a short distance apart from each other and
below the candle support and I form cuts or slits extending from the bottom of such
candle tube upwards a short distance so as to form an elastic fit between the parts.
Other means may however be adopted to secure the above result.

page_text: I, HERBERT AUGUSTUS BENHAM of 40 Chandos Street, Charing Cross, in the County
of Middlesex, General Metal Worker 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 invention relates more particularly to that class of candle lamps known as 5
"reflecting reading lamps" but is also applicable to other forms of candle lamps.
Heretofore candle lamps have been made of fixed lengths, which is sometimes
inconvenient to the user as he is unable to vary the height of the light to suit the
purpose to which he desires for the time being to apply the lamp, except by placing
it upon some independent article; according to my invention I remedy this incon- 1
venience by making the main portion of the lamp telescopic, that is to say by making
the candle tube capable of sliding up and down in a fixed tube carried by the base of
the lamp. In order to prevent injury by scratching to the exterior of the candle tube
and at the same time obtain a sufficiently firm fit between the two tubes I form the
lower end of the candle tube with circumferential rings a short distance apart from
each other and below the candle support and I form cuts or slits extending from the
bottom of such candle tube upwards a short distance so as to form an elastic fit
between the parts.
Other means may however be adopted to secure the above result.
And in order that my said invention may be more clearly understood and readily
carried into effect I will proceed aided, by the accompanying drawings more fully to
describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a vertical elevation partly in section of a candle lamp constructed
according to my invention.
Figure 2 is a vertical elevation of the lower part of the candle tube and Figure 3
is an underside view of the same.
Heretofore candle lamps have been made of fixed lengths and unadjustable as to
height of light.
According to my present invention I make the main portion or stem of the lamp
telescopic that is to say I make the candle tube a to fit within, and to be capable
of sliding up and down in a fixed tube b carried by the base, c, of the lamp. In order
to prevent injury by scratching to the exterior of the candle tube a and at the same
time obtain a sufficiently firm fit between the two tubes a. b I form the lower end of
the candle tube a with circumferential rings a¹ a short distance apart from each other
and below the candle support a² and I form cuts or slits a³ extending from the bottom
of the candle tube a upwards a short distance so as to form an elastic fit between the
parts a. b.
Other means may however be adopted to secure the above result.

page_text: 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 :-
1. Constructing the main portion or stem of a candle lamp telescopic substantially
as herein shown and described.
2. In candle lamps the combination of a candle tube a capable of sliding up and
down within a tube b fixed to the base c substantially as herein shown and described
and for the purpose stated.
3. In candle lamps a sliding tube a, formed with circumferential rings a¹ and cuts
or slits a³ in combination with a tube 6 fixed to the base c substantially as herein shown
and described and for the purpose stated.
