PROVISIONAL SPECIFICATION.
Improved Means for Securing Cycle Lamps to their Supporting
Brackets.
I, ARTHUR JOSEPH SIMPSON, of Ixion Cycle Works, Crabbs Cross, Redditch,
in the County of Worcester, Mechanic, do hereby declare the nature of this
invention to be as follows:-
This invention consists of the hereindescribed improved means for securing a
cycle lamp to its supporting bracket.
Heretofore it has been usual to make the back part of the lamp with a flattened
socket lined with indiarubber in which the lamp bracket has fitted more or less
tightly so that it is often somewhat difficult to remove the lamp therefrom. The
object of my invention is to provide means whereby the lamp can very readily be
securely fixed in place on the lamp bracket and be instantly easily released and
removed from the bracket, when required.
In carrying out my invention instead of making the back part of the lamp with
the said usual socket I provide two cars or side projections on the back part of the
lamp between which the lamp bracket fits. There is or may be also a short socket
which the outer end of the bracket enters. I provide a locking lever made with a
spring heel which, when the lever is turned in one direction against the back part
of the lamp, acts upon the lamp bracket and pinches the same against the back
part of the lamp thus securely fixing the lamp and lamp bracket together. By
turning the lever in the other direction, that is away from the part of the lamp
bracket on which the lamp fits, the said heel releases the lamp bracket and the
lamp is free to be removed therefrom. The said heel part may either be made in a
piece with the locking lever or (and this is what I prefer) the heel is made as part
of a strong spring plate which is fixed to the lever and springs slightly away from
the same when the lever is closed to clamp the lamp bracket as above described.
A set screw regulates the distance through which the said spring plate springs from
the lever and thus regulates the strength of the spring and tightens up the grip
on the bracket and also enables the heel to be set up for wear. The part of the back
part of the lamp which fits against the bracket may be lined with leather or india-
rubber cork or other suitable pliable substance so as to increase the grip and
prevent any rattling.

Brackets.
I, ARTHUR JOSEPH SIMPSON, of Ixion Cycle Works, Crabbs Cross, Redditch,.
in the County of Worcester, Mechanic, 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 consists of the herein described improved means for securing a
cycle lamp to its supporting bracket.
Heretofore it has been usual to make the bark part of the lamp with a flattened
socket lined with indiarubber in which the lamp bracket has fitted more or less
tightly so that it is often somewhat difficult to remove the lamp therefrom. The
object of my invention is to provide means whereby the lamp can very readily be
securely fixed in place on the lamp bracket and be instantly easily released an I
removed from the bracket when required.
I will describe my invention by referring to the accompanying drawings on
which
Fig. 1 represents a cycle lamp secured to the lamp bracket by my invention;
Fig. 2 is a cross sectional elevation of the back part of the lamp and supporting
bracket and the means which I employ for securing the lamp thereto;
Fig. 3 shews the same parts as Fig. 2 but with the locking lever of the back
part of the lamp turned back ready for the removal of the lamp from the
bracket;
Fig. 4 is a sectional plan through line X X of Fig. 3;
Fig. 5 shews the locking lever separately in side elevation, back elevation and
in plan;
Fig. 6 is a sectional elevation of the back part of a cycle lamp with my invention
applied in a slightly different manner to that shewn by Figs. 1, 2, 3 and 4 and
shewing also a portion of the lamp bracket to which the lamp is fixed;
Fig. 7 is a side elevation, Fig. 8 is a sectional back elevation and Fig. 9 is a
plan of the back part of a cycle lamp and lamp bracket illustrating a further
modification of my invention.
The same letters of reference indicate the same parts in all the figures of the
drawings.
I will first describe the arrangement of my invention illustrated by Figs. 1, 2, 3,
4 and 5. In carrying out my invention instead of making the back part A of the
lamp with the usual socket 1 provide two ears B1 B2 on the back part A of the
lamp between which ears the lamp bracket C fits. These ears B B project
forward towards the front of the lamp and they are by preference situated at or
near the bottom of the back part A. There is a short socket a¹ above the
ears B1 B2 which the outer or upper end of the bracket A enters and through
which the upper end of the said bracket passes so as to steady the lamp on the
bracket. I provide a locking lever D which by the pin d' or by other convenient
means is jointed to the ears B' B2. This locking lever D is made with a spring
heel d projecting from the same toward the lamp bracket C. When the lever D
is turned in one direction, that is against the back part A of the lamp as shewn in
Figs. 1 and 2, the spring heel d2 acts upon the lamp bracket C and pinches the
same against the back part A of the lamp thus securely fixing the lamp and lamp
bracket C together. By turning the lever D in the opposite direction, that is away
from the part of the lamp bracket C on which the lamp fits, the heel d' releases

page_text: the lamp bracket C and the lamp is free to be removed therefrom as shewn in
Fig. 3.
The heel part d may either he made in a piece with the locking lever D or (and
this is what I prefer) the heel is made as part of a strong spring plate d³ which
is fixed to the lever D as by the rivet d' and springs slightly away from the plate D
when the lever D is not closed to clamp the lamp bracket C as above described.
A set screw e in the lever D bears against the plate d' and regulates the distance
from which the plate d³ springs from the lever D and thus regulates the strength
of the spring and tightens up the grip on the bracket C and also enables the heel d'
to be set up for wear. The back part A of the lamp which fits against the
bracket C may be lined with leather indiarubber cork or other suitable pliable
substance so as to increase the grip of the lever aud prevent any rattling.
It will be evident that instead of the lever D being arranged to act upon the
front of the lamp bracket C as in the arrangement above described and illustrated
by Figs. 1, 2, 3 and 4, the said locking lever D may be arranged as shewn in
Fig. 6 to act upon the back of the lamp bracket C. In this case the ears B' B'
project at the back of the lamp A instead of at the front of the same.
In a further modification of my invention illustrated by Figs. 7, 8 and 9 the said
locking lever D is made to act against the side of the lamp bracket C. In this
case the ears B' B' which are fixed to the back part A of the lamp project at
the side of the same as shewn carrying the locking lever D between them the said
locking lever D in this case being made much narrower than in the arrangements
shewn by Figs. 1 to 6 both inclusive.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a cycle lamp the employment of a locking lever hinged or jointed to the
back part of the lamp and made with a projecting heel which, when the locking
lever is turned in one direction grips the lamp bracket in the back part of the lamp
or releases the bracket when the locking lever is turned in the opposite direction,
substantially as set forth.
2. In a cycle lamp the employment of the locking lever D hinged or jointed to
the ears B B formed on the back of the lamp and made with the projecting heel d
which when the locking lever D is turned in one direction grips the lamp bracket
in the back part of the lamp, or releases the bracket when the locking lever is
turned in the opposite direction, all substantially as hereinbefore described and
illustrated by the accompanying drawings.
3. In a cycle lamp made with a locking lever, for locking the lamp to the lamp
bracket as deuoted by Claims 1 and 2, the particular construction of the locking
lever D made with the spring heel d² adjustable by the set screw e to enable the
grip of the lever to be regulated, substantially as herein before described and
illustrated by the accompanying drawings.
