1, GEORGE FREDERICK REDFERN, of the firm of G. F. Redfern & Co., the General
Patent Office, No. 4, South Street, Finsbury, in the County of London, Patent
Agents, do hereby declare the nature of this invention (a communication from abroad
by F. Teste, of 6 Boulevard de Strasbourg, Paris, in the republic of France,) to be as
follows:-
This invention relates to a support for carriage lamps or lanterns.
It is well known that lamps fixed to vehicles, particularly to velocipodes, are
liable to be extinguished through the shocks produced by jolting. Many attempts
have been made to devise a simple and convenient mode of suspension for isolating
the lamp from the vehicle and it is for this reason that when drawing heavy guns, the
lamp is suspended from the collar of the leading horse. But all the apparatuses, as
hitherto constructed, have been two complicated or very inefficient and fragile.
The object of this invention is to construct such an apparatus which is simple and
consequently inexpensive, strong, and renders the suspended object practically in-
dependent of the movements of the point of suspension so that a lamp provided with
this apparatus is able to sustain the most violent jolting without causing the flame
to flicker.
The apparatus is constructed of a socket which receives a hook fixed upon the
vehicle. This socket is lined inside with india rubber to assist its adherence to the
hook. A small flange serves to hold the india rubber packing and prevent it from
coming out when the socket is removed from the hook. The socket is provided at its
middle part with a cross piece the two ends of which are turned over and formed with
holes for receiving a rod supported at its middle part by means of an eye on the
socket. The socket is made with an opening which serves to allow a supporting bar
hereinafter described, when thrown back by the action of the spring to its normal
position after an oscillation occasioned by a shock, to bear against the india rubber
lining thereby deadening the shock. The said supporting bar is T-shaped, the wings
being turned over and formed with holes like those in the cross piece of the socket
which is a little wider. This arrangement allows of the widest part of the T-shaped
bar being introduced into the cross piece and of the whole being connected together
by the introduction of the herein before described rod through the holes made in the
turned-over parts. The spring, which is of spiral form, is wound around the bar
from the middle part towards its two ends. The middle part of the spring is left
projecting and bears against the underside of the T-shaped bar and its two ends bear
against the lower part of the cross piece.
The apparatus is applicable to all kinds of lamps either directly as hereinbefore
described or by means of a socket provided in the back of the lamp.

An Improved Support for Carriage Lamps or Lanterns.
1, GEORGE FREDERICK REDFERN, of the firm of G. F. Redfern & Co., the General
Patent Office, No. 4, South Street, Finsbury, in the county of London, Patent
Agents, do hereby declare the nature of this invention (a communication from abroad
by François Teste, of 6, Boulevard de Strasbourg, Paris, in the Republic of France)

page_text: 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 a support for carriage lamps or lanterns.
It is well known that lamps fixed to non-suspended vehicles, particularly to
velocipedes, are liable to be extinguished through the shocks produced by jolting.
Many attempts have been made to devise a simple and convenient mode of sus-
pension for isolating the lamp from the vehicle and it is for this reason that when
drawing heavy guns, the lamp is suspended from the collar of the leading horse.
But all the apparatuses, as hitherto constructed, have been too complicated or very
inefficient and fragile.
-The object-of-this-invention-is-to-construct-such-an-apparatus which is simple, and
consequently inexpensive, strong, and renders the suspended object practically in-
dependent of the movements of the point of suspension, so that a lamp provided with
this apparatus is able to sustain the most violent jolting without causing the flame to
flicker and become extinguished.
In the accompanying drawing,-
Figure 1 is a vertical section of a support for carriage lamps or lanterns constructed
according to my invention, a part of the lamp or lantern being shown fixed thereto.
Figure 2 is a plan of the underside of the support.
Figure 3 is a front clevation of the socket hereinafter described, by which the
support is fixed to the lamp-supporting-hook of the carriage.
Similar letters in all the figures indicate similar parts.
The apparatus is constructed of a socket A which receives a hook-fixed-upon the-
vehicle. This socket is lined inside with india-rubber B to assist its adherence to the
hook. A small flange serves to hold the india-rubber packing and prevent it from
coming out when the socket A is removed from the hook. The socket is provided at
about its middle part, as shown most clearly in figure 3, with arms H, the ends of
which are turned over at H', H' and forined with holes for receiving a rod M,
figure 2, supported at its middle part by means of an eyo I on the socket A so as to
prevent it yielding to the pressure of the spring E placed thereon. The socket is
made with an opening G which serves to allow a supporting bar D hereinafter
described (when thrown back by the action of the spring E to its normal position after
an oscillation occasioned by a jolt or shock) to strike against the india-rubber lining B,
thereby deadening the shock. The supporting bar D is T-shaped, as will be seen
by reference to figure 2, the wings being turned down at D', D' and formed with
boles like those in the arms H of the socket A which are a little longer. This
arrangement allows of the longer part of the T-shaped bar D being placed between
the ends H of the arms Hand of the whole being connected together by the
introduction of the rod M through the holes made in the turned-over parts H' and D'.
The spring E which is of spiral forn, is wound around the rod M from the middle
part towards its two ends, as shewn clearly in figure 2. The middle part of the
spring is left projecting and bears against the underside of the T-shaped bar D and
its two ends bear against the lower edges of the armis H. A screw E' allows the
spring E to be always kept at the same tension.
The apparatus is applicable to all kinds of lamps either directly, as hereinbefore
described and illustrated in figure 1 of the drawing, or by means of a socket provided
in the back of the lamp.
When the apparatus is applied direct, as shown in figure 1, I perforate the back
of the lantern and the supporting bar D and secure them together by means of
screws or bolts and, in this case, I find it advantageous to fix the lamp-reflector
on one end of the bolt K and secure it by means of a fly-nut screwed on the other
end. This arrangement allows of the reflector being easily removed in order to clean
or repair it.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed, I declare that what I claim is :-
(1) A support for carriage lamps or lanterns made in two parts connected by a

page_text: spring connection so as to bend or yield under the shocks resulting from jolting or
vibrations and to, then return to their normal position, substantially as hereinbefore
described and illustrated in the accompanying drawing.
(2) The combination with a support for carriage lamps or lanterns of the kind
referred to iu claim 1 of a screw bolt passing through the support and serving to fix
the lamp-reflector, substantially as herein before described and illustrated in figure 1
of the accompanying drawing.
(3) The improved support for carriage lamps or lanterns herein before described
with reference to the accompanying drawing.
