CARRIAGES"
In the ordinary method of attaching lamps to carriages the tremulous or
vibratory motion of the carriage is transmitted through the lamp iron fixed on
the carriage to the lamp. This jarring or tremulous motion given to the lamp is a
source of great annoyance to the rider besides tending to injure the lamp.
My invention consists in attaching lamps to carriages in the manner hereinafter
described whereby the vibratory or tremulous motion between the lamp iron and
lamp is wholly or mainly prevented.
My said invention consists principally in interposing between socket of the lamp
iron and those parts of the lamp sitting in and bearing against the said socket a
tubular lining or collar made preferably of vulcanized india rubber but a lining or
collar made of leather or other yielding or flexible material such for example as
felt may be used in place of india rubber
I prefer to apply an india rubber lining to the socket. For this purpose I
construct the lining and socket in the following way so that the lining is secured
to and forms part of the socket.
I make the india rubber lining of a conical figure to fit accurately the interior of
the conical socket and we furnish the top of the said lining with a broad outer
flange and the bottom with a narrow outer flange. I expand the top of the conical
socket outwards so as to form a broad seat at the top for the broad flange at the
top of the lining to seat itself upon; and I make an annular shoulder at the bottom
of the socket for the narrow bottom flange of the lining to take upon; The lining

page_text: is secured in its place in the socket by the top and bottom flanges of the said
lining seating themselves respectively upon the broad top of the socket and the
bottom annular shoulder of the socket.
I prefer to make the sockets of the lamp irons by stamping in order to give them
a uniform size and figure but I do not limit myself thereto.
In attaching the lamp to the lamp iron the conical tube at the bottom of the
lamp fits in the tubular lining carried by the socket and that part of the bottom of
the lamp around the central tube seats itself upon the flange of the lining at the
top of the socket.
There is thus interposed between the contact parts of the lamp and socket of
the lamp iron a layer of india rubber whereby the shaking or tremulous motion of
the carriage is prevented from being transmitted to the lamp.
Although I prefer to apply an india rubber lining to the socket of the lamp
iron as described yet a collar of the same construction as the lining described may
be applied outside the conical tube at the bottom of the lamp iron with the same
effect.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Neville Stretton in the Great Seal Patent Office on the
4th December 1882.

In the ordinary method of attaching lamps to carriages the tremulous or
vibratory motion of the carriage is transmitted through the lamp iron fixed on
the carriage to the lamp. This jarring or tremulous motion given to the lamp
is a source of great annoyance to the rider besides tending to injure the lamp.
My invention consists in attaching lamps to carriages in the manner hereinafter
described, whereby the vibratory or tremulous motion between the lamp iron and
lamp is wholly or mainly prevented.
My said invention consists principally in interposing between the socket of the
lamp iron and those parts of the lamp fitting in and bearing against the said
socket, a tubular lining or collar made preferably of vulcanised india rubber but a
lining or collar made of leather or other yielding or flexible material, such for
example, as felt, may be used in place of india rubber.
I prefer to apply an india rubber lining to the socket. For this purpose
I construct the lining and socket in the following way so that the lining is secured
to and forms part of the socket.
I make the india rubber lining of a conical figure to fit accurately the interior of

page_text: the conical socket and furnish the top of the said lining with a broad outer flange
and the bottom with a narrow outer flange.
I expand the top of the conical socket outwards so as to form a broad seat at
the top for the broad flange at the top of the lining to seat itself upon; and
I make an annular shoulder at the bottom of the socket for the narrow bottom
flange of the lining to take upon. The lining is secured in its place in the socket
by the top and bottom flanges of the said lining seating themselves respectively
upon the broad top of the socket and the bottom annular shoulder of the
socket.
I prefer to make the sockets of the lamp irons by stamping in order to give
them a uniform size and figure but I do not limit myself thereto.
In attaching the lamp to the lamp iron, the conical tube at the bottom of the
lamp fits in the tubular lining carried by the socket and that part of the bottom
of the lamp around the central tube seats itself upon the flange of the lining at
the top of the socket. There is thus interposed between the contact parts of
the lamp and socket of the lamp iron, a layer of india rubber whereby the
shaking or tremulous motion of the carriage is prevented from being transmitted
to the lamp.
I will now proceed to describe with reference to the accompanying Drawing the
manner in which my invention is to be performed.
Figure 1 represents in elevation and Figure 2 partly in elevation and partly in
vertical section, a carriage lamp attached to the lamp iron, fixed on the carriage,
according to my invention; Figure 3 represents partly in elevation and partly in
vertical section and in plan, the lamp iron separately; Figure 4 represents in
elevation and section and Figure 5 in plan of upper and lower sides, the india
rubber conical tubular lining or collar of the socket detached.
The same letters of reference indicate the same parts in the several Figures of
the Drawing
a is the body of the lamp and b is the lamp iron fixed on the carriage; c is the
socket of the lamp iron of a conical figure; d is the india rubber lining or collar
of a conical figure which fits the interior of the conical socket c. The top of the
lining d is provided with a broad outer flange d and the bottom with a narrow
outer flange d³. The top of the conical socket c is expanded outwards so as to
form a broad seat c³ at the top for the broad flange d' at the top of the lining d to
seat itself upon. At the bottom of the socket c is an annular shoulder or seat c³
(see Figure 3) for the narrow bottom flange d³ of the lining d to seat itself upon.
It will be seen by an examination of Figure 2 that the lining d is secured in its
place in the socket c by the top and bottom flanges d², d³ of the lining seating
themselves respectively upon the broad top c* and the bottom annular shoulder or
seat of the socket c. The india rubber lining & is thus secured to and forms
part of the socket c.
e is a tube at the bottom of the body a of the lamp. The said tube e is conical
externally and is of a size and figure suitable to fit accurately in the inside of the
conical lining d in the lamp iron socket c. The said conical tube e is cylindrical
internally and is screwed with a hollow screw into which the screwed end of the
candle tube ƒ takes. Surrounding the upper end of the tube e on the lamp
body a, is an annular seat g for receiving the top flange d' of the india rubber
lining d.
In introducing the lamp into the lamp iron socket, the conical tube e on the
bottom of the lamp is fitted in the conical lining carried by the socket c and the
annular seat g around the tube e, is seated upon the flange d² of the lining das
represented in Figure 2, where it will be seen that a layer of india rubber (or other
yielding material) is interposed between the contact parts of the lamp and socket
and the shaking or tremulous motion of the carriage is thereby prevented from
being transmitted to the lamp. The lamp is 6ixed in the socket of the lamp iron
by screwing the candle tube f into the central tube e, a shoulder f2 on the said
candle tube bearing against the socket c.

page_text: Besides preventing the tremulous motion of the carriage being transmitted to the
Jamp the conical socket and lining described and represented permit of the lamp
being readily disconnected from the socket.
When a cylindrical lamp iron socket is employed the lamp requires to be raised
vertically to remove it from the socket but in sockets constructed according to my
invention the lamp may be removed from the lamp iron socket by inclining the
lamp to one side and then raising it in its inclined position.
Having now described the nature of my invention and the manner in which the
same is to be performed I wish it to be understood that I claim as my invention
of "An improvement or improvements in attaching lamps to carriages." ;-
First Making the socket of the lamp iron conical and providing it with a broad
seat at top and an annular shoulder or seat at bottom for the purposes and
substantially as herein before described and illustrated in the accompanying
Drawing.
Secondly-The combination with the socket of the lamp iron claimed in the
preceding claim of a conical lining or collar of india rubber or other yielding or
flexible material having a broad flange at top and a narrow flange at bottom for
the purposes and substantially as hereinbefore described and illustrated in the
accompanying Drawing.
Thirdly The combination with a socket and lining of the kind described and
illustrated of a conical tube at the bottom of the lamp in conjunction with an
annular seat around the said conical tube for the purposes and substantially as
herein before described and illustrated in the accompanying Drawing.
In witness whereof I the said Neville Stretton have hereunto set my hand and
seal this third day of December in the year of our Lord one thousand eight
hundred and eighty three.
