Improvements in or relating to the Lighting of Passages, Corridors,
and other Places.
I, WILLIAM GEORGE INGLEFIELD, of 33, Tatton Road North, Heaton Chapel,
near Manchester, Clerk, do hereby declare the nature of my said invention to be as
follows:-
My invention has for its object to facilitate the lighting of corridors, passages
and other places where a light is only occasionally required, or is required in
different parts of such places, as for example in places where racks are used for
holding goods, and it is desired to throw the light on any particular shelf, or
say in underground storage rooms, where the light requires to be readily moved
from place to place as the room becomes full or empty, and for many other
purposes.
To effect such transference of the light,-which for the purpose of my inven-
tion is in the form of a lamp (oil, gas, or electric),--and without necessitating
the carrying of the lamp by hand, I employ a wire or like device which I fix,
mount or distend in, or about, the upper part of the place to be illuminated,
and extending the whole of the length, distance or range to which it is desired
to use the light, or the length of the corridor or passage to be lighted.
Upon such wire I suspend the lamp, or lighting medium, by means of a ring
or loop, and a length of elastic material (by preference india-rubber), or a
spring-like device suited in length and size to the elevation at which it is desired,
the lamp shall normally hang. By thus suspending the lamp it can be traversed
along the wire to different points with the greatest ease, and when it is required
to throw a light into a lower part of a rack, or into an obscure part of the
place in which the lamp is situated, the elastic material or device allows it to
be drawn down, or brought to the required part, and when no longer required
returns it to its normal position. In like manner the flexible character of the
suspension, permits of the lamp being raised to any higher elevation, or to extend
to any angle or lateral position, and in fact round, above, beneath or through
any fixtures, or partitions, without necessitating the user being incumbered with
the weight of the lamp.
For convenience in handling or operating the lamp I may provide a tassel or
handle, and to locate it at any particular position and free the users hands,
provide hooks at different points.
When an electric lamp is used (or for that matter a gas lamp which is supplied
through a flexible tube), I provide a sufficient length of conducting wire which
will allow for the full traverse of the lamp, and such conducting wire I suspend
in loops (festoon fashion) from the carrier wire, by means of papier mache
rings or other non-conducting or suitable devices, at regular intervals, and thus
I ensure of the length of conducting wire being neatly disposed, and out of the
way, instead of being allowed to drag along the floor, or become entangled,-
with the risk of fire or danger by wear and tear on the insulating covering.

page_text: A single wire is preferred, but for the better suspension of the lamp, or for
accommodating more than one lamp, two wires may be used, and in lieu of sus-
pending the wire beneath the level of the ceiling it may be located within a
cavity of such ceiling, and in such a manner as to cause the loops of the conduct-
ing wires to be concealed from view.

Improvements in or relating to the Lighting of Passages, Corridors,
and other Places.
I, WILLIAM GEORGE INGLEFIELD, of 33, Tatton Road North, Heaton Chapel,
near Manchester, Clerk, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
My invention has for its object to facilitate the lighting of corridors, passages
and other places where a light is only occasionally required, or is required in
different parts of such places, as for example in places where racks are used for
holding goods, and it is desired to throw the light on any particular shelf, or
say in underground storage rooms, where the light requires to be readily moved
from place to place as the room becomes full or empty, and for many other
purposes.
To effect such transference of the light, which for the purpose of my inven-
tion is in the form of a lamp (oil, gas, or electric),--and without necessitating
the carrying of the lamp by hand, I employ a wire or like device which I fix,
mount or distend in, or about, the upper part of the place to be illuminated,
and extending the whole of the length, distance or range to which it is desired
to use the light, or the length of the corridor or passage to be lighted.
Upon such wire I suspend the lamp, or lighting medium, by means of a ring
or loop and a length of elastic material (by preference india-rubber) or a
spring-like device suited in length and size to the elevation at which it is desired
the lamp shall normally hang. By thus suspending the lamp it can be traversed
to different points along the wire, with the greatest ease, and when it is required
to throw a light into a lower part of, say a rack, or into an obscure part of the
place in which the lamp is situated, the elastic material or device allows it to
be drawn down, or brought to the required part, and when no longer required
returns it to its normal position. In like manner the flexible character of the
suspension permits of the lamp being raised to any higher elevation, or to extend
to any angle 'or lateral position, and in fact round, above, beneath or through
any fixtures, or partitions, without necessitating the user being incumbered with
the weight of the lamp.
For convenience in operating the lamp I may provide a tassel or handle, and
to locate it at any particular position, and for freeing the users hands, provide
hooks at different points.
When an electric lamp is used I provide a sufficient length of conducting wires
which will allow for the full traverse of the lamp, and such conducting wires I
suspend in loops (festoon fashion) from the carrier wire, by means of papier mache
rings or other non-conducting, or suitable devices, at regular intervals, and thus

page_text: I ensure of the length of the conducting wire being neatly disposed out of the
way, instead of being allowed to drag along the Hoor, or become entangled,
with the risk of fire or danger by wear and tear on the insulating covering.
When a gas lamp is used I provide a length of tubing, suspended in the same
or a similar fashion.
And in order that my said invention may be more readily understood and
carried into practical effect I have hereunto annexed a sheet of drawings and will
now proceed to describe the same with the various figures and letters of reference
marked thereon.
Fig. 1 represents a part side view, and Fig. 2 a transverse sectional view of
my improved lighting devices. Fig. 3 represents a diagram of the complete
devices on a smaller scale.
In accordance with my invention, (A) represents a wire tightly suspended or
stretched between supports (13) fixed upon the ceiling of the room to be lighted,
or other part convenient for the use of my invention.
From such wire I suspend the lamp (C) by means of an elastic (india-rubber)
cord (D), with looped end fitting around the insulator bobbin (E). Said bobbin
is a slack or easy fit, and readily slides along the wire under a slight lateral
pull, hence it permits of the lamp being transferred or traversed along the wire (A)
for its full length or range.
To supply the lamp with current it is necessary to supply a sufficient length
of conducting wires (F), to follow the lamp to its furthermost point of movement,
and to prevent such wires dragging on the floor and getting in the user's way,
or to prevent all risk of damaging the covering of the wires, and for keeping the
wires in a safe condition, I suspend them festoon fashion by hooks (G) from
wire (A), and thereby dispose them in a neat and tidy form, and, by means of
the hooks (G), in a way which permits the wires to readily lengthen out, or
close in, to accommodate the traverse of the lamp.
To allow for the pulling down of the lamp to various points, as shewn in
diagram in Fig. 3, I loosely coil an ample length of conducting wires around
the cord (D), which is, by preference, secured to the cord at the top end, and is
thus always kept free from entanglement, and allows of the quick return of the
lamp.
Each hook (G) is fitted with divided insulator bush (H) which clamps the con-
ducting wires (F) under pressure of a wing-nut. The ceiling switch or rose (I)
to which the conducting wires are connected may be at any point in the length
of the wire (A), and consequently be shorter if placed in the centre of its length
than at either end, but for freedom of movement I prefer it at one end. The
wire (A) is held taut by any suitable devices, and for additional strength, or for
carrying two or more lamps, may be duplicated.
To conceal the wires from view I may mount them in a cavity in the ceiling,
or between two suspended aprons or partitions, as shewn by dotted lines in
Fig. 2, or conceal them by other architectural devices.
To assist in operating the lamp I provide it with a loop (J) which may also
serve for hooking the lamp to a nail or bracket.
Whilst specially applicable to electric lighting I may apply my invention to
an oil or other system of lighting and although chiefly described for corridor,
store-room and like uses, it may with advantage be used on spinning and other
machinery where progressive inspection is required.
It may also be used on board ship, and in mines, hospitals, and all other
places where a travelling or portable light is required. The improved elastic
suspension may be applied to lamps suspended direct from a switch or rose, as
shewn in dotted lines in Fig. 1, and thus allow of the lamp being pulled down
to various levels.
Although I prefer the wire (A) to be horizontal it may be inclined from one,
or both of its ends, and thus serve to automatically return the lamp to one point
after using.

page_text: Having thus 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. The improved lighting appliances substantially as herein described and
shewn on the accompanying drawings.
2. In lighting appliances the use of a lamp suspended from a wire (or its
equivalent) by means of an elastic device (cord or spring), and capable of travel-
ling along said wire, as and for the purposes set forth.
3. In lighting appliances the use of a lamp suspended by an elastic device
from a wire (or its equivalent), in combination with a length of conducting wire
(or tubing) held festoon or like fashion from said wire and surrounding the said
elastic device, as and for the purposes set forth.
