PROVISIONAL SPECIFICATION.
Improvements in Flexible Supports for Electric Lamps.
I, WILLIAM WHITE, of 58 Bread Street, in the City of London, Electrical
Engineer, do hereby declare the nature of this invention to be as follows:-
In carrying electric lamps it is often necessary to make the supports such that
they can be bent so as to bring the light into various positions. My invention
relates to a construction of supports for this purpose. A support according to my
invention consists of two pieces of rigid tube the ends of which do not meet by
several inches but are connected by arms projecting from each tube and hinged
together so that the two pieces of tube can be moved on the hinge to various angles.
I connect the ends of the two pieces of rigid tube by a piece of flexible tube, and I
pass the conducting wires along the bores of the tubes thus connected. Instead of
a single joint of the kind described there may be several joints with their axes in
different planes so that the support can be bent in many or in all directions.
Dated this 14th day of February 1891.

COMPLETE SPECIFICATION.
Improvements in Flexible Supports for Electric Lamps.
I, WILLIAM WHITE, of 58, Bread Street in the City of London, Electrical
Engineer, do hereby declare the nature of this invention and in what manner the
same to be performed, to be particularly described and ascertained, in and by
the following statement :-
In carrying electric lamps it is often necessary to make the supports such that
they can be bent so as to bring the light into various positions. My invention
relates to a construction of supports for this purpose. A support according to my
invention consists of two pieces of rigid tube the ends of which do not meet by
several inches but are connected by arms projecting from each tube and hinged
together so that the two pieces of tube can be moved on the hinge to various
angles. I connect the ends of the two pieces of rigid tube by a piece of flexible
tube, and I pass the conducting wires along the bores of the tubes thus connected.
Instead of a single joint of the kind described there may be several joints with
their axes in different planes, so that the support can be bent in many or in all
directions.
The accompanying drawing shews a combination of joints such as are above
referred to in forming a bracket capable of flexure in various directions. Each
joint consists of two pairs of arms A A and B B jointed together so as to form a
hinge with open space in the middle in which may be placed a piece of flexible
tube C. The conducting wires W are led through these pieces of flexible tube C
and through the lengths of tube T which connect the successive joints.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:―
A flexible support for an electric lamp consisting of pieces of tube connected by
hinge joints arranged to allow motion in various planes, each joint consisting of two
pairs of arms hinged together with open space between them to receive pieces of

page_text: flexible tubes through which and the tubes connecting the joints the conducting
wires are passed, substantially as described.
