ARTHUR JOHN WESTMANCOTT Police Constable 22 Alfred Street Islington London N.
do hereby declare the nature of this invention to be as follows:-
My invention consists of a metal case, opening at the top, enclosing a four volt
accumulator and a flat incandescent electric lamp, silvered at back, and suspended
from a piece of chouite, which slides into a groove; the accumulator also slides into a
compartment making contact with two pieces of brass attached to the chonite,
worked by a switch, thus giving a brilliant light through a bulls-eye fixed in the
case.

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:-
My invention, which is specially applicable for the use of police or cyclists,
consists of a metal case, with an opening at the top size about 5 inches high 3 inches
wide inches deep, a small bulls eye in front, protected by a plated guard to
prevent breakage; the inside of the case is divided by means of a piece of tin
soldered on each side, the back part of which contains an accumulator with terminals
in front: about an inch from the top two similar pieces of tin are soldered on
horizontally from the front to the middle: also a similar piece is soldered on near
the bottom, to form two grooves inch wide, into which slide two pieces of ebonite
or the like.
From the top piece of ebonite is suspended a small incandescent electric lamp,
with a reflector at back; to the bottom piece is attached a small spring switch,
projecting through the front of the case.
The accumulator makes contact by means of two pieces of brass attached to the
top piece of ebonite.
Handles may be attached at the back of the case to suit requirements.
In order that my invention and the manner of operating the same may be the
better understood, I have appended the accompanying sheet of drawings, in which
Fig. 1 is a vertical side view of the lamp.
