PROVISIONAL SPECIFICATION.
Improvements in or connected with Carriage Lamp Irons.
1, HENRY VINCENT, of 33 Bath Street, Walsall, in the County of Stafford,.
Pattern Maker, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in or connected with carriage lamp irons,
and has for its object improved means whereby the said lamps may be firmly
secured in the lamp iron and prevented from any possibility of shaking therein.
I effect this as follows:-As is well known the lamp iron consists of an out-
standing socket or ring, with a slightly tapered interior which receives vertically
the stem, or as it is generally termed the "socket"-of the lamp.
At the front part of this ring, and upon its inside and for a space about one third,
of its circumference, the surface is set back or recessed, so that it may receive
therein a movable pressure plate, whose inner surface conforms to and completes
the interior line of the ring. This interior shape of the ring of course agrees.
with the shape of the lamp socket. Upon the movable plate pins are provided
which travel through holes in the ring so as to prevent its removal and guide it in
At the front of the ring a screw pin is provided having a suitable knob
or handle by which the plate may be thrust forward when desired tightly against
the lamp socket when the latter is in position.
Other forms of guiding or controlling the plate may be used with the same
result, and it desired more than one screw may be used.

Improvements
I, HENRY VINCENT, of 33 Bath Street, Walsall, in the County of Stafford,.
Pattern Maker, do bereby 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 improvements in or connected with carriage lamp irons,
and has for its object improved means whereby the said lamps may be firmly secured
in the lamp iron and prevented from any possibility of shaking therein.
In order to more fully explain this my invention I have appended hereunto an
illustrative drawing upon which are figures and numbers of reference, similar-
numbers referring throughout to the same thing or part.
Fig. 1, is a sectional view (on line A-B Fig. 2) of the invention.
Fig. 2, is a plan view of the invention.
Fig. 3. is a front view of the invention.

page_text: As is well known the lamp iron consists of an outstanding socket or ring 4, from
a stem 5 which latter is fixed to the body of the carriage &c. in the usual manner.
This socket has a slightly tapered interior which receives vertically the stem,-
or as it is generally termed the "socket" 6-of the lamp, which is shown in dotted
lines.
At the front part of this ring 4, and upon its inside and for a space about one
third of its circumference, the surface is set back or recessed, so that it may
receive therein a movable pressure plate 7, whose inner surface conforms to and
completes the interior line 8 of the ring. This interior shape of the ring of course
agrees with the shape of the lamp socket, which is generally oval, but may be
other vise. Upon the movable plate 7 pins 9, 9, are fixed which travel through
holes in the set back portion of the ring, so as to prevent its removal and also
guide it in its course. At the front of the ring a screw pin 10 is provided having
a suitable knob or handle 11, by which the plate may be thrust forward when
desired tightly against the lamp socket when the latter is in position as shown in
Fig. 1.
Other forms of guiding or controlling the plate may be used with the same
result, and if desired more than one screw may be used.
Having now particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
In carriage lamp irons the combination with the lamp iron socket 4 having the
set back portion, of the movable guided plate 7 and thrast screw 10, all constructed
and operating substantially as set forth and shown.
Dated this 1st day of February 1897.
