Improvements in or relating to Carriage Lamps.
I, PERCIVAL JOSEPH THOMAS, of the Lion Hotel, Aberkenfig, South Wales,
Licensed Victualler, do hereby declare the nature of my said invention to be
as follows:-
-
My invention relates to carriage lamps formed to receive a candle sustained by a
spring; such lamps being attached to the carriage by brackets; and the objects
of my invention are to enable an attendant to ascertain the length of the candle
remaining in the lamp without removing the cone or candle, socket screw, also
to render the attachment of the lamp more secure than heretofore, and to lessen
vibration.
According to my invention, instead of forming the cone at the upper end of
the candle of brass or other metal, I form the same of glass, by which means the
candle can be clearly seen, without the necessity of removing the cone, candle,
or socket screw, for that purpose. I also screw-thread the external upper part
of the stem of the lamp or the socket, and fit thereto a screw-threaded nut in
such a manner that the lamp is rendered secure against vibration and dishonest
removal.

Improvements in or relating to Carriage Lamps.
I, PERCIVAL JOSEPH THOMAS, of the Lion Hotel, Aberkenfig, South Wales,
Licensed Victualler, do hereby declare the nature of my said invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-

to render the attachment of the lamp more secure than heretofore, and to lessen

the candle of brass or other metal, I form the same of glass, by which means the

or socket screw for that purpose. I also screw-thread the external upper part
of the stem of the lamp or the socket, and fit thereto a screw-threaded nut in
such a manner that the lamp is rendered secure against vibration and dishonest
removal.
And in order that my said invention may be particularly described and ascer-
tained, reference is hereby made to the accompanying drawings, in which similar
letters of reference indicate corresponding parts.
Fig. 1 is an elevation partly in section, and Fig. 2 is a plan view of the glass
cone.
a is the glass cone, b is the candle, which is held in position by the upward
thrust of the spring c in the usual manner. d, d, are ventilating passages for
the entrance of air. e is a glazed window formed in the side of the lamp body.
g of
f is the ring or socket at the outer end of the bracket, encircling the stem
the lamp; this part of the stem is made slightly elliptical, the ring f correspond-
ing therewith to prevent the lamp turning upon its vertical axis.
stem is screw-threaded to receive the clamping nut h, whereby the lamp is firmly
held to the bracket and rendered secure against vibration and dishonest removal.
Notches, are formed in the periphery of the disc of the cone for the passage
therethrough of lugs which engage in recesses for securing the cone in
position.
At g¹ the
By means of the glass cone light is carried downwards to the chamber in
which the candle is fitted, so that by its aid and (or) by means of the window e
the length of candle remaining unconsumed can be clearly seen from the outside
of the lamp, without the necessity of removing any of the parts.
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. In a carriage lamp, the combination therewith of a glass cone a and
window e, substantially as and for the purpose described.
2. In a carriage lamp of the description aforesaid, the combination therewith
of a screw threaded portion of the stem g and clamping nut h, substantially
as and for the purpose described.
Dated 17th May 1900.
