Improvements; in connection with Lamps for Cycles and other.
Vehicles.
I, WILLIAM PREWETT, Cabinet Maker, of Cheriton, near Alresford, in the County;
of Hants, do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in connection with lamps for cycles and
other vehicles, and the object is to provide means whereby a supplementary beam of
light may be thrown in any direction parallel with a plane passing through the lens
and the wick of the lamp. In carrying my invention into effect, I proceed in or
in about the following manner. In the side of the lamp I provide an opening
preferably circular. Within this opening (or in a separate opening, provided in a
plate attachable to the side of the lamp and over the opening therein) is a ring filled,
with a disc of clear glass and free to be turned through a complete revolution in the
hole. To this ring is attached by soldering, hingeing or otherwise one edge of a
silvered reflector, the reflecting surface being towards the side opening above
mentioned. The angle between the reflector and the glazed ring should be 45 degrees,,
but the angle may be more or less than that. The reflector may be kept at the
right angle or strengthened in position by a suitable stay or strut extending from
the ring to the outer edge of the reflector. Assuming the lamp to be alight and the
reflector (if it is hinged) opened out then the light will pass out of the lamp, through'
the glazed ring and striking the silvered surface be reflected therefrom. By revolving,
the ring (and consequently the reflector which is attached to it) a beam of light can be
passed from the rear overhead to the front and thence downwards to the rear, or
vice versa, thus affording means for reading direction posts, names of streets, inspecting
parts of the vehicle, aiding the finding of articles dropped, in the road,, and for
any like purposes. There may be a reflector on each side of the lamp..

page_text: same is to be performed to be particularly described and ascertained in and by the
following statement:-
My invention relates to improvements in connection with lamps for cycles and
other vehicles and the object is to provide means whereby a supplementary beam of
light may be thrown in any direction parallel with a plane passing through the
lens and the wick of the lamp. In carrying. this invention into practice I proceed
in or in about the following manner, making reference to the accompanying sheet of
drawings in which Fig. 1 is a horizontal section, Fig. 2 a front view with reflector in
use. Fig. 3 front view of the appliance shut up. In the side a of the lamp I
provide a circular opening b. Within the opening (or in an opening provided in a
plate attached to the side of the lamp) is a ring c filled with a disc of glass d, the
ring being turned over as at e to enable it (the ring) to be rotated a complete
revolution and at the same time not fall out. To the ring c is attached by soldering,
hingeing or otherwise, but preferably by the hinge of one end of the frame g of a
silvered reflector h, the reflecting surface being towards d. The angle between d and h
should be 45 degrees but may be more or less. The reflector h may be kept at the
proper angle and strengthened in position by a suitable stay j attached or hinged to
a plate or projection attached to or forming part of the ring c. The stay j is
preferably in the form of a loop as shown in the drawings, one end of the said stay
being passed over one end of the reflector frame g so as to come behind a pin
provided thereon. The end bar of loop j is kept against by the beak end m
of the catch n which can be turned on the pin o attached to the back of g.
By partly rotating m on o so as to bring m.into the position shown in dotted
lines Fig. 2, g will fall down and cover d and the loop j can then be shut over ; and
kept down by rotating m on o so as to bring one of the beak ends m over the end
bar of the loop (Fig. 3). For cheapness the hinges might be omitted and the
reflector fixed at the proper angle and supported by a rigid stay of any suitable kind.
The action is as follows. Assuming the lamp to be alight and the reflector h (if
hinged) opened out, then the light from the lamp will pass out through the glass
disc d and striking h be reflected therefrom at right angles to an imaginary line
passing from side to side of the lamp. By revolving the ring c (and consequently the
reflector h) a beam of light can be passed from the front overhead to the rear and
thence downwards to the front again or vice versa, thns affording means for
reading direction posts, names of streets, inspecting parts of the vehicle, facilitating
the finding of articles dropped in the road, ascertaining how the lamp is burning
and for any other purpose. Although I find a reflector on one side of the lamp to
be generally sufficient one may be provided at each side if desired. As my invention is
capable of considerable variation in detail and mode of carrying out without departing
from its essential features I do not restrict myself to the precise shapes, relative
proportions or dispositions of parts as shown in the accompanying drawings or
mentioned in the above specification.
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. Providing cycle and other lamps with an opening in one or in each side, in
which opening is free to revolve a ring filled with a glass disc the said ring having
hinged or otherwise fastened to itself (or to a suitable attachment) a silvered
reflector the reflecting surface of which is retained towards the above mentioned
glass disc at an angle of forty five degrees (or more or less) by a hinged or other
suitable stay the whole substantially as described in the above specification and
.exemplified in the accompanying drawings.
2. Providing cycle and other lamps with an opening in one or in each side, through
which opening is free to pass a beam of light from the interior of the lamp, the said
beam being caught on a suitably inclined reflector outside the lamp, the said reflector
being capable of rotation so as to cause the before mentioned beam of light to sweep

page_text: from the front overhead to the rear and thence downwards to the front or vice versa,.
the whole provided for and operating substantially as described in the above
specification and exemplified in the accompanying drawings.
