HERBERT LISLE, 5, Cuthill Road, Camberwell, Professional Vocalist, do hereby
declare the nature of this invention to be as follows:-
A lamp that is perfectly level in whatever position the vehicle is in, whether
carriage or cycle, also shipping.
A lamp with two cones at the back and a cone cach side working on ball bearings
allowing the body of the lamp to always attain its perpendicular and level position.

Improvements in Lamps.
I, HERBERT LISLE, 5, Cuthill Road, Camberwell, London, S.E., Professional
Vocalist, 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:-
This invention for improvements in lamps has for its object to provide a lamp
adapted to be fixed to a carriage, cycle, or other vehicle or a ship or the like, and
which shall be always vertical whatever the position of the vehicle; and consists
in supporting the lamp in bearings in a frame, and in supporting the frame in
bearings in a bracket, the axes of the bearings being at right angles to one another
and the bracket being adapted to be fixed to the vehicle. The axis of the lamp
bearing passes through the lamp well above its centre of gravity.
In the accompanying sheet of illustrative drawings; Fig. 1 is a side elevation
of a cycle lamp constructed according to this invention, and Fig. 2 is a plan of
the same. Figs. 3 and 4 are sections through a bearing of the lamp body and
the bracket bearing respectively.
On each side of the lamp body a is a cup or ball race b and a similar cup or
ball race c is formed in each side arm of the frame d. Balls are inserted between
the races b and c and either the edge of the race is turned over so as to secure
the bracket to the lamp, but so that the lamp can rotate in the bearing on the balls,
or the distance between the arms of the bracket can be adjusted as shown.
In the end of the frame are two cups or ball races e and on a pin f fixed to the
bracket g are two similar cups or ball races 1. As before, the balls are inserted
and either the edge of the one cup turned over the edge of the corresponding
cup so as to fix the frame to the bracket 9, or the two cups are adjusted on a

page_text: central spindle as shown. The bracket 9 is shown as a spring bracket but any
other suitable form of bracket may be employed.
Ball bearings are shown but any other suitable bearings may be used.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. A lamp supported in a frame on an axis passing through the lamp body
well above its centre of gravity, and the frame supported on a bracket about an
axis at right angles to the axis supporting the lamp body, substantially as
described.
2. A bracket for supporting a lamp body consisting of a frame adapted to sup-
port the lamp body in bearings and a bracket supporting the frame in bearings
having an axis at right angles to the bearings of the frame, substantially as
described.
3. A bracket for supporting a lamp body consisting of a frame adapted to
support the lamp body and a bracket supporting the frame in bearings having
an axis parallel to the plane of the frame substantially as described.
4. The improved lamp substantially as described with reference to the drawings.
Dated this 6th day of October 1898.
