Improvements in Lamps for Velocipedes and in Brackets therefor.
We, SAMUEL SNELL of Skinner Lane Birmingham in the County of Warwick,
Manufacturer, and ALBERT WILLIAM SANDERSON of Woodfield Villas, St. Paul's
Road Birmingham, aforesaid, Foreman, do hereby declare the nature of this invention
to be as follows :-
This invention relates to lamps for bicycles, tricycles and other velocipedes, as
hereinafter described; and consists essentially in mounting the said lamps, upon a
universal and yielding socket arm, stem or bracket support.
To the back of the lamp, and disposed at right angles thereto, a carrier arm or
bracket stem is rigidly connected or secured thereto, and which said arm or bracket
stem consists of a stalk, having at its outer end, a bulb or protuberance, which works
within a like shaped cup, carried at the back side of the carrying socket; that is, the
connection between the back of the lamp, and the inside face of the carrying socket,
(by which the lamp is secured to a velocipede) is made by a ball and socket joint, of
which the cup part is carried by the carrying socket, and the stem part with its
bulbous end, is carried by the lamp.
To a bracket, plate, or arms carried at the back of the lamp, and to a plate, bracket
or arms carried by the carrying socket, distended coiled springs are disposed in such
a manner, as to keep the lamp with respect to the carrying socket, always in a central
position, and in a state of equilibrium.
The springs are preferably stretched from four points or from the four corners of
the brackets, plates or arms.
By providing lamps with yielding connections as described, vibration and tremor of
a machine is not imparted to the lamp; or if imparted, is materially stopped off, by
the ball and socket joint and springs keeping it in a central position.
Instead of the supporting bracket being secured rigidly to the back of a lamp, it
may be connected by a hook or other like connection.
In this modification last described, the yielding socket arm or bracket, and the
carrying socket, and the parts carried by the socket, are made separate from the
lamp.

Improvements in Lamps for Velocipedes and in Brackets therefor.
We, SAMUEL SNELL of Skinner Lane Birmingham in the County of Warwick,
Manufacturer, and ALBERT WILLIAM SANDERSON of Woodfield Villas, St. Pauls
Road Birmingham, aforesaid, Foreman, 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 relates to lamps for bicycles, tricycles and other velocipedes, as
herein-after described; and consists essentially in mounting the said lamps, upon a
universal and yielding socket arm, stem or bracket support.
To the back of the lamp, and disposed at right angles thereto, a carrier arm or bracket
stem, is rigidly connected or secured, and which said arm, or bracket stem, consists
of a stalk, having at its outer end, a bulb or protuberance, which works within a like
shaped cup, carried at the back side of the carrying socket; that is, the connection
between the back of the lamp, and the inside face of the carrying socket, (by which
the lamp is secured to a velocipede) is made by a ball and socket joint, of which the
cup part, is carried by the carrying socket, and the stem part with its bulbous end, is
carried by the lamp.
To a bracket plate, or arms carried at the back of the lamp, and to a plate, bracket
or arms carried by the carrying socket, a coiled spring or coiled springs, is or are
disposed in such a manner, as to keep the lamp with respect to the carrying socket,
always in a central position.
Instead of the supporting bracket, being secured rigidly to the back of a lamp, it
may be connected to it, by a hook or other like connection.
We will now proceed to describe with reference to the accompanying drawing, the
manner in which the same is to be performed.
Figure 1 represents partly in elevation, and partly in section, a velocipede lamp,
and lamp carrying socket, provided with a yielding connection, constructed according
to our said invention; and by which means, the lamp is allowed free motion of its
carrying socket in every direction within certain limits.
Figure 2 represents partly in elevation, and partly in horizontal section, a plan or
top side view of figure 1.
The same letters of reference indicate corresponding parts in figures 1 and 2.
a is a lamp, b is a bracket arm, fixedly secured at its inner end, to a plate a³,
disposed within the middle of the back of the said lamp.
The stalk 62 of the bracket arm b, is provided at its outer end, with a ball, or
bulbous protuberance 6³, which works within a hollow cup, or ball socket c, fixedly

page_text: secured to the inner side of the lamp carrying socket d. This socket is open at top
and bottom, and through which, the bracket end e², of a bracket e, which is secured to
a machine, passes.
The lamp carrying socket d, is adjustable, by drawing together, the divided back
parts d², by a screw f, which passes through them; and further, the said socket has a
rubber lining g, for stopping off tremor to the lamp.
Encircling the bracket arm b, 62, and cup, or ball socket c is a coiled spring h, the
one or inner end of which, is fixedly or rigidly connected to the bracket arm plate 64,
or to the back of the lamp, whilst the other or outer end ³, is rigidly connected to
the cup c, or to the lamp carrying socket d.
By arranging the parts as described, the lamp is connected to its carrying socket,
by a yielding connection, which is stayed in position by a ball and socket connection,
thereby allowing the lamp to move with a free motion in every direction within
certain limits.
The yielding connection, and stay, which passing axially through its middle, is
hooded by enclosing parts i, 12, the former i is carried upon the back of the lamp,
whilst the latter, is secured to the carrying socket.
Figure 3 represents partly in horizontal section, and partly in elevation, our
invention applied to a combined bracket and clip; upon the former, a lamp is
secured, whilst the latter embraces the head or other tubular framing portion of a
machine.
b is the bracket arm, 62, the stalk thereof, with a ball 63 at its outer end, which works
within a cup socket carried by a clip d.
The bracket arm plate 6, is secured to the bracket end e, e², of a bracket e, and
upon this end, e², an open-ended socket secured at the back of a lamp, passes.
The bracket arm b, is encircled by a coiled spring h, attached at one end h³, to the
plate 64, and at the other end h³, to the cup socket c.
Figure 4 represents another form of our invention in connection with a lamp
carrying or bracket arm socket, and a bracket arm, upon the latter of which, a lamp is
secured.
b is the bracket arm, with stalk, and ball 62, 63. d is the bracket arm socket,
carrying the cupped socket e, wherein the ball joint 63, works. h is a coiled spring
secured at its outer ends as aforesaid. e, e², is the lamp carrying bracket.
Instead of the ball joint being carried by the bracket arm socket, it may be carried
at the back of the lamp, or by the lamp carrying bracket, as in figures 3 and 4.
Instead of the lamp being connected to the bracket arm socket d, as in figures 1
and 2, or the lamp carrying bracket, to the clip as in figure 3, or to the lamp carrying
bracket and bracket arm socket as in figure 4, they may be connected by four or
other number of coiled springs, disposed at suitable points around the bracket arm
stay as aforesaid.
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.-
First. Connecting velocipede lamps, or lamp carrying brackets or sockets, with
their machine connection sockets, brackets, or the like, by a ball and socket joint, or
its equivalent, situated either at the end of a stem, or stalk, or connected directly to,
the parts as aforesaid, substantially as described, and set forth.
Secondly. The combination with a ball and socket stay connection 6, 62, 63, and C,
of a single coiled spring h, fixedly connected at its outer ends, substantially as set
forth in the several figures of the drawing.
Thirdly. Connecting lamp carrying brackets e, e², to clips d, or their equivalents,
by a ball and socket joint arrangement or stay, for the purpose substantially as set
forth in figure 3.
Fourthly. The combination with a lamp carrying bracket e, e², ball and socket

page_text: arrangement b, b³, c and clip d, of a coiled spring h, rigidly connected at its outer
ends, to the parts e and c, or d, respectively, substantially as set forth in figure 3.
Fifthly. Connecting lamp brackets e, e², to bracket sockets d, by a ball and socket
device, or stay, substantially as described and set forth in figure 4.
Lastly. Combining with a lamp carrying bracket e, e², ball and socket arrange-
ment b, 62, 63, c, and socket d, of a single coiled spring h, secured at its outer ends,.
substantially as set forth.
