PROVISIONAL SPECIFICATION.
Improvements in or relating to Lamps for Velocipedes.
We, DAGOBERT MARCUS, and JAMES HARRY WALKER trading as Messrs.
Henry Eades & Co. of 28 Masshouse Lane Birmingham in the County of
Warwick, Manufacturers, do hereby declare the nature of this invention to be as
follows:-
This invention relates to lamps for velocipedes and consists of improved means
for connecting the lamp to the supporting socket by which it is carried on the
bracket attached to the machine.
In carrying our invention into effect we provide four projecting ears or lugs
on the back of the lamp attached to or forming part of the same. The extremities
of these lugs are in the form of cup shaped sockets and are arranged to act as
bearings for the carrying arms as hereinafter described.
On the front part of the supporting socket, four similar shaped ears or lugs
are placed forming the rear bearings for the carrying arms or connecting and
supporting frame.
Two separate arms or frames are furnished, one turning in the lower set of
bearings and the other in the upper, so that both being of the same length from
one bearing point to the other, they form an articulated parallelogram and cause
the lamp to move when shaken by jolting or otherwise parallel to itself and in
a vertical plane, thus keeping it always in an upright position.
Each arm or frame is furnished with an extension cup shaped socket place in
an opposite direction to those on the lamp and supporting socket, and so arranged
when placed together as to form a spherical recess. Into each recess is placed
a metallic sphere or ball which is enclosed therein, thus connecting the joints
together, the whole forming a ball or cup jointed parallelogram in which there
will be little danger of rattling, through the parts wearing loose.
A helical or other spring is employed as in ordinary lamps for holding the lamp
in an oblique position.
We may in some cases attach to each extremity of the arms or frame, a metallic
sphere or ball in the form of an extension knob, or it may be hemispherical or
of other similar form so arranged as to fit into a corresponding cup shaped bearing
on the back of the lamp and supporting socket.
as to
Or we may when desired place a lining of leather, india-rubber, cork, or other
yielding material between the extension knob and socket bearing, so
prevent any vibration caused by shaking or jolting of the machine to which it is
attached.
Or we may make the extension knob of india-rubber, vulcanite, cork or other
similar material to obtain the same effect.
We may also employ a different number of arms and may modify our invention
in any detail as may be necessary to the carrying of the same into effect without
departing from the nature thereof.
The arrangement thus described can be carried into practice in a cheap and
expeditious manner as it dispenses with the use of screw and pin joints and other
unnecessary arrangement as hitherto employed.

Improvements in or relating to Lamps for Velocipedes.
We, DAGOBERT MARCUS, and JAMES HARRY WALKER, trading as Henry
Eades & Co., of 28 Masshouse Lane, Birmingham, in the County of Warwick,
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 relates to lamps for velocipedes and consists of improved means
for connecting the lamps to the supporting socket by which it is carried on the
bracket attached to the machine.
In carrying our invention into effect we provide four projecting cars or lugs on
the back of the lamp attached to or forming part of the same. The extremities of
these lugs are in the form of cup shaped sockets and are arranged to act as bearings
for the carrying arms as hereinafter described.
On the front part of the supporting socket four similar shaped cars or lugs are
placed forming the rear bearings for the carrying arms and the frames which
support and connect the arms.
Two separate sets of arms with their connecting frames are furnished, one turning
in the lower set of bearings and the other in the upper, so that both being of the
same length from one bearing point to the other, they form an articulated
parallelogram and cause the lamp to move when shaken by jolting or otherwise,
parallel to itself, and in a vertical plane, thus keeping it always in an upright
position.
Each carrying arm is furnished at each end with an extension cup shaped socket
placed in an opposite direction to those on the lamp and supporting socket, and so
arranged that when the cup shaped sockets on the lamp or supporting socket are
placed together with the cup shaped sockets on the carrying arms, as to form a
spherical recess. Into each recess is placed a sphere or ball which is enclosed
therein, thus connecting the joints together, the whole forming a ball or cup jointed
parallelogram in which there will be little danger of rattling through the parts
wearing loose.
A helical or other spring is employed to maintain a proper resistance to the
vibration of the lamp.
We may in some cases attach to each extremity of the arm or frame, a spherical
knob, or the said knob may be hemi-spherical or of other similar form so arranged
as to fit into a corresponding cup shaped bearing on the back of the lamp and
supporting socket.
We may also employ a different number of arms and may modify our invention
in any detail as may be necessary to the carrying of the same into effect without
departing from the nature thereof.
The arrangement thus described can be carried into practice in a cheap and
expeditious manner as it dispenses with the use of screw and pin joints and other
unnecessary arrangements as hitherto employed.
We will describe our invention in reference to the accompanying drawings, the
same letters of reference indicating similar parts throughout.
Figure 1, is a front elevation, Figure 2 a plan, and Figure 3 a plan of the
underside of our improved lamp.
Figures 4, 5, 6, 7, 8, 9 and 10 are detail views.
Figures 11, 12, 13, 14 and 15 are modifications of our invention.
A is the lamp, B the supporting socket for attaching the lamp to the bracket C
of the machine D, D, are ears or lugs on the back of the lamp and forming part of
the same connected together by a crosspiece D' and shown separately at Fig. 6, or
in a modified formn in Figs. 9 & 10. The extremities of the ears or lugs forming

page_text: cup shaped bearings E, F, F, are similar cup shaped bearings attached to the
supporting socket B.
G, G, G, G, are four arms having cup shaped bearings E³, E', E, E, one being
shown separately at Figure 8. H Figure 7 represents a metallic frame with two
extension pieces I, which are folded over the arms G shown in section at Figures 4
and 5, thus binding and securing the four arms together and forming an articulated
parallelogram. The parts G and H may be made in one piece as shown at
Figure 74.
The cup shaped bearings E on the arms G and the cup shaped bearings E on
the lamp, when placed together form a spherical recess L, into which is placed a
metallic sphere shown at K Figure 2, thus forming a ball and cup joint, in which
rattling and the wearing of parts is entirely obviated.
Figure 9 shows a different method of forming the cup shaped bearings E on the
back of the lamp, also the cup shaped bearing F on the supporting socket B
consisting of a metallic tube D³, into each end of which is placed a cup shaped plug
forming the bearing F, and which may be of metal or other suitable material.
In Figure 10, the cup shaped bearing is made from a short length of metal tube,
the ends being bent inward into the form of a cup bearing F.
Figures 11 and 12 are modifications in which the metal sphere K forming an
extension knob is attached to the end of each arm G and works freely in the cup
shaped bearing D on the back of the lamp, and also the cup shaped bearing F on
the supporting socket B.
Figures 13 and 14 represent a similar arrangement in which the extension
knob K is attached to the back of the lamp and to the supporting socket in which
case the cup shaped bearing is formed on the ends of each arm.
Figure 15 shows an arrangement in which the extension knob is hemi-spherical,
instead of spherical.
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 a lamp for velocipedes provided with jointed carrying arms and their
connecting frames between the lamp and the supporting socket, the joints being
formed by cup shaped bearings and spheres, so as to keep the lamp upright and
allow it to move in a vertical plane parallel to the supporting socket, substantially
as described and illustrated in the drawings and for the purpose set forth.
2. The construction of the projecting cup shaped ears or bearings D, D, attached
to the lamp aud carrying socket, substantially as described and illustrated and for
the purpose set forth.
3. In the construction and combination of the carrying arms G and the cup
shaped bearings E³, connected together by a frame H substantially as described
and illustrated in the drawings and for the purpose set forth.
4. The modifications arranged and combined in the manner shown in Figures 11,
12, 13, 14 and 15 as described and set forth.
