PROVISIONAL SPECIFICATION.
Certain Improvements in Cycle Lamps.
We, FRANK POWELL and FRANK HANMER, trading together as Powell and
Hanmer, of 2324 Aston Road, Birmingham, Warwickshire, Lamp Manufacturers,
do hereby declare the nature of this invention to be as follows:-
This invention has reference to those lamps for bicycles tricycles and other
velocipedes in which the fount or oil vessel forms the removable bottom of the
lamp body and in order to obtain access to the wick and burner the said fount or
oil vessel has to be removed leaving the bottom of the lamp body open.
One part of this invention consists in an improved construction of the lower part
of the lamp body and of the upper part of the fount or oil vessel which fits therein
and this part of our said invention is carried out as follows:-We form an inwardly
projecting rim or rib round the bottom of the lamp body which can conveniently be
done by wiring the bottom edge of the body or by simply turning in the bottom
edge and we form a corresponding rebate round the top of the fount, that is to say
the top of the fount is reduced in size to fit in the body the bottom of the body
abutting on the shoulder round the fount so that the joint of the body and fount is
flush outside or nearly so. The small holes in the body to admit air to the flame
are situated as near to the bottom of the body as possible so that the reduced upper
part of the fount which projects into the body will form a baffle all round to
disperse the air and prevent the air impinging directly on to the flame.
In order to removably secure the fount in position in the bottom of the lamp
body we provide a small projecting rib on one side of the upper rebated part of
the fount which engages with the said rib or rim on the bottom of the body, and at
the opposite side of the fount we provide the usual spring catch adapted to engage
with the body.
Another of our improvements consists in making the reflector at the back of the
flame in a piece with the cone which projects from the lamp body and carries the
lense. In the top and in the bottom of that part of our combined cone and back
reflector which projects into the lamp body we provide an opening. The bottom
opening admits the flame and the top opening allows the heat and sinoke (if any)
to pass up through the top of the lamp. The combined reflector and cone are
readily cleaned by making the lense hinged to the cone as is now often done.

Certain Improvements in Cycle Lamps.
We, FRANK POWELL and FRANK HANMER, trading together as Powell and
Hanmer, of 232 Aston Road, Birmingham, Warwickshire, Lamp Manufacturers,
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 has reference to those lamps for bicycles tricycles and other
velocipedes in which the fount or oil vessel forms the removable bottom of the
lamp body and in order to obtain access to the wick and burner the said fount or
oil vessel has to be removed leaving the bottom of the lamp body open.

page_text: This invention consists in the improved construction of the lower part of a lamp
body and of the upper part of the fount or oil vessel which fits therein and our
invention is carried out as we will describe by referring to the accompanying
drawings on which
Fig. 1 is a back elevation Fig. 2 is a sectional elevation and Fig. 3 is a part
sectional side elevation of a cycle lamp with the lower part of its body and the
upper part of the fount or oil vessel constructed according to this invention and
Fig. 4 is a side elevation Fig. 5 is an end elevation and Fig. 6 is a plan of the
fount or oil vessel of the said lamp separately. These figures shew our invention
applied to a cycle lamp in which the fount is secured to the body by the usual
spring catch and Figs. 7, 8, 9, 10, 11 and 12 illustrate our invention applied to a
cycle lamp body in which the fount is secured to the lamp body by being made to
slide therein. Fig. 13 illustrates a slightly modified form of our invention and
Fig. 14 shews a further modification.
The same letters of reference indicate the same or corresponding parts in all the
figures of the drawing.
A is the lamp body and B is the fount or oil reservoir of the same, only so much
of the lamp body being shewn as is necessary to illustrate our invention. In
carrying out our invention we form an inwardly projecting rim or rib c round the
bottom of the lamp body A which can conveniently be done as shewn in Figs. 2, 3
and 7 by wiring the bottom edge of the body or as shewn in Fig. 13 by turning in
the bottom edge c or by turning the bottom edge c inwardly and upwardly as shewn
in Fig. 14 and we form a corresponding rebate d round the top of the fount B, that
is to say the top of the fount B is as shewn in Figs. 2, 3, 4, 5, 6, 7, 10, 11, 12, 13
and 14 reduced in size to fit in the body A the bottom of the body abutting on a
shoulder e round the fount so that the joint of the body A and the fount is as shewn
in Figs. 1, 2, 3, 8, 9, 13 and 14 flush on the outside or nearly so. The small holes f
in the body A to admit air to the flame are as shewn in Figs. 1, 2, 3, 7, 8, 9, 13
and 14 situated as near to the bottom of the body as possible so that the reduced
upper part of the fount B which projects into the body will form a baffle all
round to disperse the air and prevent the air impinging directly on the flame.
When the fount B is required to be secured in the lamp body A. by means of the
usual spring catch gas in the example illustrated by Figs. 1, 2, 3, 4, 5, and 6 we
provide a small projecting rib on that side of the upper rebated part d of the fount
opposite to the spring catch g which rib engages as shewn in Fig. 2 with the rib or
rim c on the bottom of the lamp body so that in attaching the fount to the lamp body
that side of the lamp body where the rib his has to be first inserted in the lamp body
so that the rib h will engage over the rib or rim c, the fount is then turned up into
the horizontal position shewn in Fig. 2 and the other side of the fount secured by
the usual spring catch 9 engaging over the usual projecting part g' which is fixed
to the lamp body. When however our invention is applied to one of those cycle
lamps in which the fount is made to slide in or out of the lamp body, then instead
of the rib at the side of the fount we provide two smaller ribs h³ ³ at the front
and at the back of the fount as shewn in Figs. 7, 10, 11 and 12 these ribs ³ ³
being a little above the shoulder e so as to engage over the rib or rim c at the front
and at the back of the lamp body which thus form runners to permit of the fount
sliding in or out of the lamp body. In this example of our invention as in other
cycle lamps the fount when it has been slid into position in the lamp body is there
secured by the usual sliding door i which is moved down as shewn in Figs. 8 and 9
so as to overlap the side of the fount and maintain the fount in place.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
--
1. In cycle lamps the employment of an inwardly projecting rim or rib such as c
round the bottom of the lamp body in combination with a corresponding rebate
such as d round the top of the fount so that the body and fount will be flush or ·

page_text: nearly flush outside and the rebated part of the fount will form a baffle to the air
rushing in through the holes f to the flame substantially as herein before set forth
and shewn upon the accompanying drawings.
2. In cycle lamps having their bodies and founts made as denoted by Claim 1 the
employment of a rib such as h¹ or ribs such as ³ ³ on the rebated part of the
fount adapted to engage over the rim or rib c on the body and secure or assist in
securing the fount in the lamp body substantially as hereinbefore set forth and
shewn upon the accompanying drawings.
3. In combination with a cycle lamp body the use of the herein described
improved oil fount made with a rebated top d to fit in the lamp body and form a
baffle to the air rushing in to the flame substantially as hereinbefore set forth and
shewn upon the accompanying drawings.
4. The manufacture and sale of cycle lamps having the lower parts of their
bodies and the upper parts of their founts constructed substantially as and for the
purposes herein before set forth and illustrated by the accompanying drawings.
