COMPLETE SPECIFICATION.
An Improved Means for Lighting Warehouses, Workrooms, and
other Places where Artificial Light is Required in Different.
Parts of said Warehouses or Places at Different Times.
We, F. H. ROYCE & Co. LIMITED of Cooke Street, Hulme, Manchester,
Manufacturing Electricians, and WILLIAM GEORGE INGLEFIELD of Sunnyside,
Urmston, Clerk, all in the County of Lancaster, 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 :-
This invention relates to an improvement in the means for lighting warehouses,..
workrooms, and other places where artificial light is required in different parts of said.
warehouses or places at different times.
The object of this invention is to dispense with the necessity of employing several
lamps and to enable one lamp or a reduced number of lamps to serve the purpose of"
lighting at the place or places required.
In the accompanying drawing
Fig. 1 shows an arrangement according to this invention for lighting places such as.
herein before named by means of electric or other lamps: the dotted lines represent
some of the different positions in which said lamps may be placed.
Fig. 2 shows a lamp drawn to an enlarged scale that may be employed in.
combination with said arrangement.
In these views similar letters refer to similar parts.
In this invention we stretch by means of a tightening screw or other appliance a.
horizontal wire of any length as 6 or an equivalent, between two brackets placed any
distance apart: said brackets may be fixed to and extend from the front of a row of
shelving or they may be brackets as c that are extensible and fitted to the ceiling or
other convenient place. Intervening brackets may be employed to assist in supporting
the wire b which may be carried and extend around a part or the whole of the interior
of a room. The aforesaid wire when supported by extensible brackets may be placed
at either a higher or a lower elevation by pushing in or withdrawing the rods c
which are formed to slide within the brackets c and retained in position by means of
a spring as c² which acts on the aforesaid rods c'. We construct the handle d¹ of the
lamp d with a slit or opening d² through which to pass the wire & when the lamp is
placed on any part of said wire. If the lamp employed is electric, the cord e is
connected to a switch at any convenient place as at q, a change being made in the
connection to any other point when the lamp is required at a greater distance than
the length of the cord e will permit. In applying our invention, when it is desired to
have artificial light at any particular place, the lamp d is caused to travel along the
wire 6 the necessary distance by pulling the cord e to which said lamp is connected.
If a supporting bracket intervenes the lamp is lifted off and replaced on the wire b by
passing said wire through the slit d' and if the lamp is required beyond the limit of
the extent of the cord e, electrical connection is made at a place nearer to where the
light is wanted.
By these means the light or lamp may be removed to any point as at g and brought
immediately opposite to the place where light is necessary.
When it is preferred to alter the elevation of the light, the length of the brackets c
and the height of the wire b may be varied as shown by dotted lines on the drawing,
the lamp & being caused to travel thereon in the manner herein before described.

page_text: When candle, oil, or other lamps are employed which are not electric an ordinary
cord may be attached to said lamp in place of the electric wire or cord e.
Having now particularly described and ascertained the nature of this our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
In warehouses, work rooms and other places where artificial light is required, the
combination with an electric, candle, oil, or other lamp of an extended horizontal wire
as 6 or an equivalent supported on and between either fixed brackets fitted to and
extending from the front of a row of shelving, or extensible brackets as c that are
fitted to the ceiling or otherwise for the purpose and in the manner substantially as
herein before described.
b
2nd. In warehouses, work rooms and other places where artificial light is required,
the use of an extended horizontal wire as 6 supported on and between either fixed
brackets or extensible brackets as c, and in combination therewith a lamp in which
the handle or upper portion is constructed with a slit or opening as d' through which
to pass the aforesaid wire b in the manner and for the purpose substantially as herein
before described.
3rd. In warehouses, work rooms and other places where artificial light is required
the use of an extensible bracket as c in combination with an extended horizontal
wire as 6 and electric, candle, oil, or other lamps as d substantially as and for the
purpose herein before described.
4th. The improved means for lighting warehouses, work rooms, and other places
where artificial light is required in different parts of said warehouses or places at
different times, substantially as herein before described.
