IMPROVEMENTS IN VELOCIPEDE AND CARRIAGE LAMPS
Year: 1884

page_text: I, JOSEPH LUCAS, of the firm of Joseph Lucas and Harry Luca's trading as
Joseph Lucas and Son Little King Street, Birmingham, Lamp Manufacturers do
hereby declare the nature of my invention for IMPROVEMENTS IN VELOCIPEDE
AND CARRIAGE LAMPS to be as follows:-
My improvements are chiefly applicable to that class of lamp known as
Velocipede "Head" Lamps, but may also be applied to Lamps for Carriages or
other Vehicles.
First I desire to prevent the tendency of these "Head" lamps to shake or
jolt off the brackets or holders by which they are attached to the Velocipede or
the Carriage, and I may conveniently describe my method as follows.
I split or divide, vertically by preference, the socket usually attached to the back
or side of these Lamps, and provide a screw or screws for the purpose of drawing or
pinching together the parts of the socket so divided, when the lamp is placed on
the bracket or holder which carries it, and by this means the lamp is prevented
from shaking off the vehicle through the jolting of travelling.
Secondly I desire to provide Velocipede and other Lamps with an improved
glass, which in the case of Velocipede Lamps will serve the double purpose of
side-light" and "back-light." The glass may be of any convenient size, tliickness,
or shape. Its face is flat, and one (or more) of its edges is square or at right-
angles to the face of the glass-The edge opposite to the square one must be
bevelled to an obtuse angle with the face of the glass.
This form of glass will allow of some of the rays of light passing through it in
the ordinary or lateral direction, and other rays will be thrown at a right angle or
say backwards through the square edge of the glass.

Improvements in Velocipede and Carriage Lamps.
I, JOSEPH LUCAS of the firm of Joseph Lucas and Harry Lucas, trading as
Joseph Lucas and Son; of the "Tom Bowling" Lamp Works, Little King Street,
Birmingham Lamp Manufacturer do hereby declare the nature of my invention
for IMPROVEMENTS IN VELOCIPEDE AND CARRIAGE LAMPS, and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
My improvements are chiefly applicable to that class of lamps known as
Velocipede Head Lamps, but may also be applied to lamps for Carriages and other
vehicles.
First I desire to prevent the tendency of these "Head" Lamps to shake or jolt
off the brackets or holders by which they are attached to the Velocipede or the
carriage, and I may conveniently describe my method as follows.
I split or divide, vertically by preference, the socket A A Figure 1, usually
attached to the back or side of these lamps-The screw B, draws the divided edges
of the socket together, and so will clamp the socket on to the bracket of a
Velocipede or other Vehicle, and prevent the lamp jolting off when travelling.
Secondly I desire to provide Velocipede and other lamps with an improved
glass, which will serve the double purpose of side. light and back light, but
as I have registered the design of this glass, I make no claim for it in this
specification.
Having now, described the nature of my said invention, and in what manner the
same is to be performed, I declare that what I claim is
The use on Velocipede and other Lamps of a divided socket with a clamping]
screw or screws, for the purpose of preventing the Lamp from jolting off its bracket
or holder.
