We PERCY PALMER BURT of Birmingham in the County of Warwick Lamp
Manufacturers, and SAMUEL BRUCE EDMONDS, of the same place Manager, do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to construct the attachment portion of the lamp so
as to enable the lamp to have a perfectly steady bearing and avoid being affected by
the oscillation or jolting of the vehicle to which it is attached this is effected in the
following manner. Two metal tubes are fixed to the lamp in each of which works a
metal rod attached to the socket piece by which the lamp is held on the machine or
vehicle, at the upper portion of each is fixed a plug or washer of leather or other
suitable material through which the rod passes, at the lower end of each rod is a
plunger by preference also of leather and at the bottom of each tube a buffer of india
rubber or other elastic material.
Between the fixed upper plugs of leather in the tubes and the plungers upon the
rods are fixed spiral or other suitable springs so that when the oscillation or jolting
of the vehicle takes place any movement to the lamp is at once counteracted by the
springs.
In order to secure a perfectly steady and noiseless action, two wing pieces which
are lined with leather or other suitable material are attached to the socket, these
wing pieces clipping the outside of the metal tubes which act as a guide.
This
By this arrangement a perfectly steady bearing is obtained for the lamp and the
risk of the lamp being put out by the oscillating and jolting of the vehicle is obviated
and by constructing the various parts as described all noise is prevented.
invention is especially adapted for the requirements in connection with Bicycle and
Tricycle lamps but may also be applied to carriages and other instances where the bad
effect from oscillation is desired to be obviated.

An Improved Attachment for Bicycle, Tricycle, and other Lamps.
We PERCY PALMER BURT of Birmingham in the County of Warwick Lamp
Manufacturer and SAMUEL BRUCE EDMONDS of the same place Manager, 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,
reference being had to the accompanying drawings and to the letters and figures
marked thereon :-
The object of this invention is to construct the attachment portion of the lamp so
as to enable the lamp to have a perfectly steady bearing and avoid being affected
by the oscillation or jolting of the vehicle to which it is attached. this is effected
in the following manner. Two metal tubes are fixed to the lamp in each of which
works a metal rod attached to the socket piece by which the lamp is' held on the
machine or vehicle at the upper portion of each tube is fixed a plug'or washer of
leather or other suitable material through which the 'rods passes' at the lower end of
each rod is a plunger by preference also of leather and at the bottom of each tube a
buffer of india rubber or other elastic material or if preferred a small spiral or other
spring may be introduced. Between the fixed upper plugs of leather in the tube
and the plungers upon the rods are fixed spiral or other suitable springs so that
when the oscillation or jolting of the vehicle takes, place any movement of the lamp
is at once counteracted by the springs. In order to secure a. perfectly steady and
noiseless action two wing pieces which are lined with leather or other suitable material
are attached to the socket these wing pieces clipping the outside of the metal tubes
which act as a guide. By this arrangement a perfectly steady bearing is obtained for
the lamp and the risk of the lamp being put out by the oscillating and jolting. of the
vehicle is obviated and by constructing the various parts as described all noise is
prevented.
This invention is especially adapted for the requirements in connection with Bicycle
and Tricycle lamps but may also be applied to carriages and other instances where the
bad effect froin oscillation is desired to be obviated.
Referring to the Drawings Fig. 1 is a back view of a lamp shewing the new
arrangement by which a steady bearing is obtained and Fig. 2 is a sectional elevation
of the same.
(aa) are the two tubes fixed to the lamp (6 b) are two metal rods working in the
tubes (aa) (c) is the socket piece by which the lamp is held on to the machine or
vehicle and to which the rods ( b) are attached by the arms (dd).(ee) are plugs or
washers through which the rods (bb) pass (ƒƒ) are, plungers at the ends of the rods
(bb) and fitting into the tubes (a a) (g g) are the buffers of elastic material at the
bottom of the tubes (a a) (ss) are spiral springs surrounding the rods' between the
fixed upper plugs (ee) and the plungers (ff) (h h) are the wing pieces attached to
the 'socket piece (c)-these-wing pieces (hh) clipping the sides of the tubes (a a) the
tubes thus acting as a guide.

page_text: The dotted lines (a) on Fig. 1 show the extent of play given by this
arrangement.
By thus suspending the lamp to the socket piece by which it is attached to the
vehicle the effect which oscillation or jolting ordinarily has upon the lamp is
overcome.
We wish it to be understood that we do not confine ourselves to the precise form of
socket and wings illustrated nor to the exact position shewn for the rods and tubes as
all these parts may be required to be varied to suit different descriptions of carriage
and other lamps.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim is:
1st. The improved attachment for Bicycle Tricycle and other lamps consisting of a
rod or rods working into a tube or tubes for the purposes described and illustrated.
2nd. The improved attachment for Bicycle Tricycle and other lamps consisting of
rods attached to a socket piece and working in tubes on the lamp the socket piece
having wings or attached pieces to act as guides all substantially as described and
illustrated.
