Improvements in the Manufacture of Carriage Lamps and their
Holders or Attachments to the Bodies of Carriages.
ROBERT PARKER DODD 37 Waterloo Street, Birmingham in the County of
Warwick Civil Engineer, do hereby declare the nature of my invention for IMPROVE-
MENTS IN THE MANUFACTURE OF CARRIAGE LAMPS AND THEIR HOLDERS to be as
follows :-
In the ordinary method of attaching lamps to carriages it is often very difficult to
remove the lamps from their fastenings after they have been in use but a short time
as they get wedged or jammed in their fixings, by the vibration of the carriage and
also further fastened, by rusting of the part or parts in contact, as it allows the wet
to get into or between the parts.
This is entirely removed by my invention as I make a waterproof junction between
the lamp holder and the lamp, and also make the lamp stronger and simpler in its
construction and neater and more compact in its appearance as by my invention the
lamp iron is wholly or mainly concealed and there are no screws or loose parts, to
get loose, rattle or become worne thus giving greater security and strength, with in-
creased durability than in the usual and ordinary methods of lamp iron attachments
fixed to the bodies of carriages and to the back or body of the lamp.
By my invention the light being freed from the vibration will burn steadier
and give better results.
The accompanying drawings shows substantially the nature of my invention and
how it is to be accomplished.
I construct the body of the lamp with a double back or casing at the back, or, if
preferred at the side of the lamp, in this casing I place a metal box, Figs. 1, 2, 3,
and 4, and marked D. This box is firmly soldered or rivetted on to the back of the
lamp, or, if preferred it can be made in one piece solid with the back of the lamp by
the casting process. I however prefer to make it as shown, but do not confine myself
thereto.
In this metal box I place a lining of india rubber, leather, felt, or other such
yielding substance but preferrably india rubber, this lining is interposed between the

page_text: body of the lamp, and the lamp iron or holder which is bolted or secured to the body
of the carriage, effectually cuts off all vibration and forms a yielding substance for a
seating for the lamp iron, clinging thereto and forming a junction that wet will not
penetrate, thereby preventing any rust forming on the lamp iron, also allowing the
ready removal of the lamp, the metal box being so formed that there is a small flange
at the bottom to prevent the rubber lining being withdrawn when the lamp is taken
off Figs. 1, & 2.
Figs. 5, & 6, shew elevation of rubber lining and marked C.
Figs. 1, & 2 shews section of rubber and marked C.
The lamp iron or holder which is bolted or secured to the body of the carriage, is
shewn in Figs. 1, 2, 7, & 8, and marked A. Figs. 7, & 8, being the sectional
elevation and Figs. 1, & 2, shewing position of the lamp iron, or holder when fixed
to the lamp. Figs. 1, & 2 shews the lamp with the relative position of the metal box
in conjunction with the rubber lining and the lamp iron, the part marked D. being
the metal box, the part marked C. being the rubber lining, the part marked A. being
the lamp iron or holder.
I do not confine myself to the lamp iron being made strictly in accordance with the
sectional elevation as shown in Figs. 7, & S, as the same can be made oval in shape, or
convex, or concave, or one side Hat and the other side convex, or concave, but I
prefer to make as shewn.

ROBERT PARKER DODD 37 Waterloo Street Birmingham in the County of
Warwick, Civil Engineer, 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 :-
In the ordinary method of attaching lamps to carriages it is often very difficult to
remove the Lamps from their fastenings after they have been in use but a short time as
they get wedged or jammed in their fixing by the vibration of the Carriage and also
further fastened by rusting of the part or parts in contact as it allows the wet to get
into or between the parts. This is entirely obviated by my invention as I make a
waterproof junction between the lamp holder and the lamp and also make the lamp
stronger and simpler in its construction and neater and more compact in its appearance
as by my invention the lamp iron or holder is wholly or mainly concealed and there
are no screws or loose parts to rattle or become worn thus giving greater security and
strength with increased durability than in the ordinary method of lamp iron attach-
ments fixed to the bodies of carriages and to the back or body of the lamp.
By my invention the light being freed from the vibration will burn steadier & give
better results.
The accompanying drawings shew substantially the nature of my invention and
how it is to be accomplished.
I construct the body of the lamp with a double back or casing or if preferred at
the side of the lamp. In this casing I place a metal box Figs. 1 & 2 being the sections
Fig. 3 the elevation Fig. 4 sectional plan at bottom and Fig. 5 sectional plan at top
and marked D. This box or casting is firmly soldered or rivetted on to the back or
side of the lamp, as shewn in Figs. and 2 and marked E, or if preferred it can be
made in one piece solid with the back or side of the lamp by the casting process.
however prefer to make it as shewn but do not confine myself thereto.
I
In this metal box I place a lining of india rubber, leather, felt or other such yielding
substance but preferably india rubber, this lining being between and interposed
between the body of the lamp and the lamp iron or holder effectually cuts off all
vibration and forms a yielding substance for a seating for the lamp iron, clinging
thereto and forming a junction that wet will not penetrate, preventing any rust
forming on the lamp iron but allowing the ready removal of the lamp..
The inetal box f form with a small flange or inner projection at the bottom to
prevent the rubber lining being withdrawn when the lamp is taken off the lamp
iron.
Figs. 8 and 9 shews elevations of rubber lining and marked C. Figs. 1 and 2 shew
sections of rubber lining and also marked C.

page_text: The lamp iron or holder which is bolted or fixed to the body of the carriage is
shewn in Figs. 1, 2, 6 and 7 and marked A. Figs. 1 & 2 being the sections and
Figs. 6 & 7 being the elevations.
Figs. 1 & 2 shew the lamp with the relative positions of the metal box in con-
junction with the rubber lining and the lamp iron.
The parts marked D. being the metal box, the parts marked C. being the rubber
lining, the parts marked A being the lamp iron or holder, and the parts marked E.
heing the body and lining of the lamp.
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
1st. The construction of the metal box with a flange or inner projection at the
bottom and fixed on the back or side of the body of the lamp between the outer
body of the lamp and the inner lining of the lamp or reflector substantially as
shewn & described in the accompanying drawings.
2nd. The construction of the rubber lining and the interposition of the rubber
lining between the lamp iron or holder and the metal box substantially as shewn &
described in the accompanying drawings.
In witness whereof I the said Robert Parker Dodd have hereunto set my hand
this 5th day of May in the year of our Lord One thousand eight hundred
and eighty seven.
ROBERT PARKER DODD.
