Improvements in Lamps for Velocipedes.
I, ALBERT WILLIAM SANDERSON of 57 Beech Road Spark Hill in the County
of Warwick, Foreman do hereby declare the nature of my said invention to be
as follows:-
My invention has for its object improvements in lamps for velocipedes and refers
to the method of mounting such lamps upon their support so as to reduce the
amount of vibration to the lamp and this I effect in a cheap simple and effective
manner.
In carrying the invention into effect a projecting hook is securely fixed upon
the back of the lamp and a projecting eye securely fixed upon the carrying socket
which is attached to the velocipede for the purpose of supporting the lamp.
Between the back of the lamp upon which the eye is fixed a coiled spring is
mounted within which the said hook and eye are contained and this spring is
compressed sufficiently for the hook to be linked into the eye leaving the spring
under considerable compression by which means the vibration to the lamp is
materially reduced.
Instead of mounting the hook and spring upon the back of the lamp a false back
may be provided upon which the spring and hook would be mounted and this false
back may be placed either outside or inside and secured to the back of the lamp
in any suitable manner. In the case of the false back being inside an aperature
would be formed in the back of the lamp to allow the spring to be passed
through.
The hook may be fixed upon the carrier and the eye upon the back or the one
projection may be formed of two eyes a short distance apart in which case the
other projection is provided at the end with two arms each of which work in one
of the eyes or the two centres at the end of the spring may be connected by two
hooks, two eyes, loops, rings, hinge or chain.
I am aware that previously the back of the lamp has been connected to the
carrying socket on the velocipede by a ball and socket joint with a compression
spring to form tension between them, but this has been a somewhat expensive
arrangement while in the case of my present invention I gain the same advantages
at a much less cost. I may however considerably cheapen the manufacture of the
ball and socket joint set forth in the previous Patent No. 5546 A.D. 1887 by
forming the cup which receives the ball, in one piece with the plate upon which the
spring is mounted which plate is left sufficiently open at the back to allow the stem
and ball to be passed through until the ball rests in the socket where it is retained
by the tension caused by the coiled spring, the stem being secured to the plate at
the other end as before.

Improvements in Lamps for Velocipedes.
1, ALBERT WILLIAM SANDERSON of 57 Beech' Road Sparkhill, Birmingham,
Foreman do hereby declare the nature of my said 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 has for its object improvements in lamps for velocipedes and refers
to the method of mounting such lamps upon their supports so as to reduce the
amount of vibration to the lamp and this I effect in a cheap simple and effective
manner.
In carrying the invention into effect a projecting hook is securely fixed upon the
back of the lamp and a projecting eye securely fixed upon the carrying socket
which is attached to the velocipede for the purpose of supporting the lamp.
Between the back of the lamp upon which the hook is fixed and the carrying
socket upon which the eye is fixed a coiled spring is mounted within which the
said hook and eye are contained & this spring is compressed sufficiently for the
hook to be linked into the eye leaving the spring under considerable compression
by which means the vibration to the lamp is materially reduced.
Instead of mounting the hook & spring upon the back of the lamp a false back
may be provided upon which the spring & hook would be mounted and this falsc
back may be placed either outside or inside and secured to the back of the lamp
in any suitable manner. In the case of the false back being inside, an aperture
would be formed in the back of the lamp to allow the spring to be passed
through.
The hook may be fixed upon the carrier and the eye upon the back or the one
projection may be formed of two eyes a short distance apart in which case the
other projection is provided at the end with two arms cach of which work in one
of the eyes or the two centres at the end of the spring may be connected by two
hooks, two eyes, loops, rings, hinge, or chain.
I am aware that previously the back of the lamp has been connected to the
carrying socket on the velocipede by a ball & socket joint with a compression of
spring to form tension between them but this has been a somewhat expensive
arrangement while in the case of my present invention 1 gain the same advantages
at a much less cost.
I may however considerably cheapen the manufacture of the ball & socket joint
set forth in the previous Patent No. 5546 A.D. 1887 by forming the cup which
receives the ball in one piece with the plate upon which the spring is mounted
which plate is left sufficiently open at the back to allow the stem and ball to be
passed through until the ball rests in the socket where it is retained by the tension
caused by the coiled spring the stem being secured to the plate at the other end
as before.
In order that my invention may be clearly understood & more easily carried into
practice I have appended hereunto a double sized sheet of drawings upon which I
have fully illustrated the nature of my said improvements together with several
modifications of the same.
Figure 1 shews a general side view of a tricycle lamp with my improved device
attached thereto and shewn partly in section.
Figure 2, is a plan of the device shewn in Figure 1 the spring being shewn in
section.
Figure 3., is a back view of the, lamp with the socket part F removed.
Figure 4., is a sectioual plan shewing a modification in the connecting arrange-
ment.
Figure 5., is a view of the connecting arrangement shewing another modification.
Figure 6., is a view of a carrying bracket for use with existing lamp.

page_text: Figure 7 is a sectional elevation shewing the improvement upon my former
Patent as will be hereafter described.
Referring to Figures 1 & 2 on the drawings I provide the false back a¹ to the
lamp A and upon this false back a¹ I fix by solder or brazing the metal disc a² into
which the hook B is screwed. The hook B is linked with the eye B1 which has
its end screwed into or otherwise attached to the metal disc with the intermediate
expansion coiled spring E to retain the links in the position shewn. At the back
of the plate a screw thread is formed on to which of the carrying socket F is
screwed to receive the bracket end f. An aperture is formed in the back of the
lamp A to allow the attachment to be passed through from the inside of the lamp
until the plate a' meets the back of the lamp a' where it is secured by the screws d'
which enter the lugs as which are formed on the inside plate a to receive them.
The covering socket D is also attached to the back of the lamp by the screws (
or by other similar means so as to secure the whole together and at the same time
admits of the covering socket being readily taken off to gain access to the spring
arrangement or the whole arrangement can be easily removed by passing it through
the inside of the lamp. The reflector is provided to form the inside face of the
lamp & for covering the plate a'.
Of course I may simply attach iny hook B to the back of the lamp without the
aperture & removable arrangements or I may attach the eye B' to the lamp at
that end in which case the hook B would be at the other end.
In the case of Figure 4 I provide at the one end the projection K having the
two arms &k which work in the eyes m & m' formed on the projection Mat
the other end while in Figure 5 the two ends N & N¹ are pivoted together on the
pin around which the spring P is coiled having one end bearing against the
underside of N at n³ and the other end supporting the part N at n.
Figure 6 shews the two ends of any of the before mentioned arrangements.
adapted to be attached to existing lamps & machines the clip R being provided for
attachment to the machine and the socket S for attachment to the lamp while the
internal connection may be in accordance with any of the modifications already
described.
In the case of Figure 4 sufficient liberty is allowed for the insertion of the
arms & in the eyes m & m² when the spring is contracted by bringing the arm
over to the one side and the eyes may be slightly closed afterwards to prevent the
arms coming out but this latter is not necessary.
In the case of the improvement upon the socket joint set forth in my previous
Patent I form the socket or cap T for receiving the ball in one piece with the
plate which receives the spring E and this cap I leave sufficiently open at the
back to allow the ball V and stem to pass through into their respective positions
as shewn the head of the ball V being provided with the screw head groove v² to
enable the stem to be screwed into the plate W at the other end the tension being
retained by the spring E as before. In place of having one spring E I may have
more than one in which case the springs would be arranged around, on the outside
edge of the plate.
Having now particularly described and ascertained the nature of my said inven-
tion & in what manner the same is to be performed I declare that what I
claim is
1st. The improvements in lamps for velocipedes consisting of the hook & cyc
attachment B and B for connecting the lamp with the carrying bracket in com-
bination with the spring or springs substantially such as and for the purpose herein
set forth & shewn.
2nd. In improvements in lamps for velocipedes the carrying arrangement mounted
upon the separate plate a' in combination with the aperture formed in the back of
the lamp and means for securing the plate to the lamp: substantially as and for the
purpose herein set forth and shewn.

page_text: 3rd. In improvements in lamps for velocipedes the covering socket D made
removable substantially as and for the purpose herein set forth & shewn.
4th. In improvements in lamps for velocipedes the arrangement shewn and
described with regard to Figure 5.
5th. In improvements in lamps for velocipedes the cap or socket T and plate ¹
in one piece with the aperture for allowing the ball to pass through into position
substantially as and for the purpose herein set forth & shewn.
Dated this 6th day of May 1891.
