SPRING BRACKETS OR CARRIERS FOR MOUNTING VELOCIPEDE LAMPS
Year: 1885

page_text: I, FREDERICK WILLIAM COCKS, of 10, Braemar Road, West Green, Tottenham
in the county of Middlesex, Clerk, do hereby declare the nature of this invention
for "SPRING BRACKETS OR CARRIERS FOR MOUNTING VELOCIPEDE LAMPS," to be
as follows:
Brackets for velocipede lamps as hitherto constructed are carried rigidly by the
machine and the lamps have been supported from the same by springs to prevent
or lessen vibration or shock on the lamp and so avoid its being extinguished
thereby.
Such arrangement has not been entirely satisfactory.
By my invention I mount velocipede lamps on a spring bracket, whereby
I cushion their movements in a much more effective manner than when the lamp
carries springs and is attached to a rigid bracket.
I arrange a vertical bracket having horizontal ends or extensions supporting
between them a rod or stem and parallel with this I place a second rod or stem
fitted in the said horizontal ends or extensions of the said vertical bracket.
I arrange a slide working on the face of the vertical bracket and on the said rods
or stem I place spiral springs on each end of the slide which springs may be
adjustable by set screw and washer or otherwise.
The slide is extended forwards to carry the socket for the lamp clip.
The vertical bracket carries for a head lamp a horizontal arm to fit the head of
a bicycle or tricycle or it can be fitted to be adapted to other parts of velocipedes.
Instead of mounting the lamp on the socket carried by the slide I may dispense
with the same and may support the lamp by the springs between the horizontal
extensions of the vertical bracket.
In this case I make the rods or stems encircled by the springs (which may be
adjustable as before), to slide in the horizontal extensions of the vertical bracket
and carry slides or supports to fit the top and bottom of the lamp so that the
springs are both at the top and bottom and act as before described.

page_text: If desired, in this form, I may make the bracket telescopic and adjustable to fit
different sized lamps.
In either case I may dispense with two guide rods or stems and use only one
and adapt a pin and guide slot in the vertical bracket to keep the lamp from
twisting, which is also prevented by the use of two guide rods or stems.
In some cases I may vary the style of spring used but I prefer the spiral
variety.
I may also vary the details of the spring bracket according to the variety of
lamp to be mounted on the same.

I, FREDERICK WILLIAM COCKS of 10 Braemar Road West Green, Tottenham,
in the County of Middlesex do hereby declare the nature of my invention for
SPRING BRACKETS OR CARRIERS FOR MOUNTING VELOCIPEDE LAMPS and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
I join by means of a slide or other suitable device, two pieces of metal in such a
way that one piece, designed for carrying a lamp, is capable of moving vertically
along the second piece, such vertical motion in an upward or in a downward
direction being controlled by a spring or springs so as to break the force of any
shock tending to disturb the lamp when travelling; this second piece is rigidly
connected with the velocipede by a screw, clamp or other suitable device.
Fig. 1. shews a bracket consisting of one part A, to be fixed to a velocipede at
the extremity a and having two projecting extensions a¹, a³ supporting a rod or
stem b and likewise a second rod or stem c. These rods or stems pass through the
piece B having one end d so shaped as to fit the usual lamp socket and the other
end e sliding along the vertical part of A. The vertical motion upwards is controlled
by spring C and the motion downwards by spring D, acting round stem b.
Fig. 2. shews parts A and B capable of relative motion along the stud or stem b
fixed to A and piercing B, and and along the stud or stem c fixed to B and piercing A.
The tension of springs C and D can be regulated according to the requirements of
the lamp, by means of a screwed stop E.
Figures 3 and 4 shew another form of sliding connection between parts A
and B.
B in this case consists of a tube e open at it's lower extremity and closed at the
upper one.
This upper end is pierced to allow the stem b, shewn separately
on Fig. 4, to pass through freely but yet to retain spring C. A piston ring a' is
fixed to the rod b by means of the set screw a', which is free to slide up and down
along a slot in the tube e, and so, whilst admitting of vertical motion, will prevent
the part B from turning round on part A.
E is a stop through which the lower end of 6 is free to work, and which closes
up the end of tube e, to which it is locked at any desired height by the head of
screw e passing through the slot.
The shape of extremity a of part A may be varied so as to be attachable to
different parts of velocipedes.
Fig. 3. a shews A terminating in a barrel suitable for a revolving axle.
The shape and construction of my improved lamp bracket may be varied in a
number of ways, for instance, it may be enlarged so as to admit of the lamp being
introduced between springs C and D, the part B forming a frame round the lamp,
or else part B may be dispensed with, the lamp itself taking A's place, and being
supported by springs C and D between horizontal projections on part A

page_text: The shape and material of the springs may vary and the sliding action may be
checked by a single spring held in such a way as to act as two springs, (e.g. C and D
on figs. 1 and 3 might be parts of one single piece held in the centre); or a greater
number of springs may be used where the form of the brackets renders this
desirable.
Now I am aware that lamps have been constructed and used in such a way that
when attached to a velocipede they were suspended on or froin springs, but
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. A separate bracket or carrier containing in itself an arrangement for
controlling the up and down motion of that part to which a lamp is to be
attached.
2. The spring C working substantially as described and checking or breaking
any shock tending to throw the lamp upwards.
3. The regulating screw E on Fig. 2. and the adjustable stop E on Fig's. 3 and 4
operating substantially as described.
4. The arrangement of spring-bracket substantially as described with reference
to Fig. 3 of the accompanying drawings.
