Street, London, for the Invention of "A NEW AND IMPROVED LIGHT HOLDER."
A communication from abroad by Louis Tampier, of Bordeaux, in the French
Republic.

PROVISIONAL SPECIFICATION left by the said James Ledger at the Office
of the Commissioners of Patents on the 13th October 1876.
"A
JAMES LEDGER, Engineer and Patent Agent, of 61, Fleet Street, London.
NEW AND IMPROVED LIGHT HOLDER." A communication from abroad by Louis
Tampier, of Bordeaux, in the French Republic.
This Invention consists in a new and improved light holder for cellars, work-
shops, mines, and other purposes, whereby the light is always kept in a vertical
position by simple and effective means.
The following is the manner of constructing a light holder furnished with a
lamp according to this Invention. The lamp is an ordinary suspension lamp sus-
pended from a crescent-shaped support, to which is fixed a rod or spindle made to
pass through the lid of a socket fixed at the extremity of the handle of the light
holder. The end of the said rod or spindle may be conical or spherical, and rests
against a flat or convex washer inside the socket aforesaid.
A guide also inside
the socket keeps the spindle or rod in position, and a collar or projection on the
said spindle prevents it coming out of the socket.
When a candle is used instead of a lamp it is made to pass through a spring
suspended ring or collar, and, if desired, a weight is fixed by means of springs at
the bottom of the candle to help in keeping it steady.
By the above simple arrangement of suspension lamp or candle and rod or spindle
(which serves as an axis) the light may be carried about without fear of its loosing
the vertical position.

James Ledger, Engineer and Patent Agent, of 61, Fleet Street, London.
NEW AND IMPROVED LIGHT HOLDER." A communication from abroad by Louis
Tampier, of Bordeaux, in the French Republic.
This Invention consists in a new and improved light holder for cellars, workshops,
mines, and other purposes, whereby the light is always kept in a vertical position
by simple and effective means.
The following is the manner of constructing a light holder furnished with a lamp
according to this Invention. The lamp is an ordinary suspension lamp suspended
from a crescent-shaped support, to which is fixed a rod or spindle made to pass
through the lid of a socket fixed at the extremity of the handle of the light holder.
The end of the said rod or spindle may be conical or spherical, and rests against a
flat or convex washer inside the socket aforesaid. A guide also inside the socket
keeps the spindle or rod in position, and a collar or projection on the said spindle
prevents it coming out of the socket.
When a candle is used instead of a lamp it is made to pass through a spring
suspended ring or collar, and, if desired, a weight is fixed by means of springs at
the bottom of the candle to help in keeping it steady.
By the above simple arrangement of suspension lamp or candle and rod or spindle
(which serves as an axis) the light may be carried about without fear of its losing
the vertical position.
And in order to explain this Invention more fully I will now proceed to describe
the means whereby it may be put into practical effect, reference being had to the
illustrative Sheet of Drawing accompanying these presents and to the numeral
figures and letters of reference marked thereon respectively, as follows:-
DESCRIPTION OF THE DRAWING,
Figure 1 is an elevation, partly in section, of a light holder furnished with a
Jamp constructed according to this Invention.
A is an ordinary suspension lamp suspended from a crescent-shaped support B,
the ends of which b, b', are turned over so as to prevent the lamp from rocking.
To the support B is fixed a rod or spindle C, made to pass through the lid D of a
socket or tube E fixed at the extremity of the handle F of the light holder. The
end of the rod or spindle C may be conical at G or spherical as at G₁, G, G¹¹,
Figures 2, 3, and 4, and works against a flat washer H or convex one H¹, Figure 4,
resting against the end of the handle F. A guide K inside the socket or tube E
keeps the spindle or rod C in position, and a collar or projection L prevents it
coming out the said socket or tube.
When the lamp is provided with a glass, crowned or not by a sinoke consumer,
the glass holders M, Figure 5, affixed to the lamp are to be placed as shown at M²,
Figure 6.
Figure 7 is an elevation, partly in section, of a light holder constructed to receive
a candle. A is the candle, held in position by a spring ring A', Figure 8, suspended
to the support B. This support revolves with the spindle or rod C, constructed
and working in the same inanner as the lamp above described.
In order to keep the candle steady and increase the sensitiveness of motion a
weight suspended by three springs, Figure 9, is placed at the lower end of the said
candle. The same object is attained with the lamps by adding a weight at the
bottom thereof.
Figure 10 is a sectional elevation of a candle holder used for household and
general purposes. The candle A is held in a suspended tube B, inside of which is
a spring B which keeps the said candle always against the top b of the tube B.
The spindle or rod C passes through the centre of a dish or saucer D, and works
against a washer H secured by the nut K.

page_text: The above construction of light holder allows the light to be always kept in a
vertical position by means of the universal joint formed by the combination of the
suspension of the light and revolving motion of the support of the said light by
means of the spindle or rod working in the socket.
Having now described and set forth the nature and object of this Invention for
"A New and Improved Light Holder," I would remark, in conclusion, that what
I claim as my Invention and desire to secure by the herein in part recited Letters
Patent is, "A new and improved light holder for cellars, workshops, mines, and
other purposes, formed by the combination of the suspension of the light from a
support revolving by means of a spindle or rod in a socket, the said spindle or
rod abutting against a washer, substantially as described and represented.
In witness whereof, I, the said James Ledger, have hereunto set my hand
and seal, this Thirteenth day of April, in the year of our Lord One thousand
eight hundred and seventy-seven.
JAMES LEDGER. (L.S.)
