PROVISIONAL SPECIFICATION.
Sunshade or. Umbrella for Bicycles, Motor Cars, Boats and the like.
GEORGE FITZJAMES DARKER, of 21, Palace Square, Norwood, London, S.E.,
Member of the Royal College of Surgeons, Eng., Licentiate of the Royal College
of Physicians, London, do hereby declare the nature of this invention to be as
follows:-
A horizontal shade, supported by three horizontal supports hinged together at
one end by vertically or horizontally rivited hinges, these three supports being
held apart when in use by a transverse bar, and further the above hinge is so
made as to have a vertical flap on which the supports can turn through 270°.
This vertical flap is in turn attached to a jointed main vertical support which fits
in a metal pocket fixed to the fork of the back wheel (in a bicycle) & to the
seat pin by twisted metal strips or clamps. The above frame is made of wood or
metal & held in position by stays & cords.
Sunshade or Umbrella for Bicycles, Motor Cars, Boats and the like.
GEORGE FITZJAMES DARKER, 21, Palace Square, Norwood, S.E., Surgeon &
Physician, 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 a horizontal shade of any material (silk etc.) supported
by three horizontal supports represented in Fig. I by the lines NH, Y H and M H
hinged together at H by a hinge, a diagramatic sketch of which is seen in Fig. II.
The shade held out tight on the stretch by the silk cotton, or waterproof etc.:
being attached to the rods N H and M H, and these rods NH and M H are kept
separated when the shade is in use by a cross rod Z this is fastened to one
rod M H by two screw eyes one fastened (screwed) into the rod M, H the other
into one end of Z and the two eyes looped or hooked together. There is a pin in
the other end of Z which passes into a screw eye in N H. When in use the
shade, is prevented from flapping backwards by the cord O attached to Y, H.
Just in front of where Z crosses H and the other end of the cord O is hooked
into an eye in the support S as high up as is convenient. There are also two other
cords which can be hooked into an eye in distal extremity of Y H, i.e. the
extremity furthest away from the hinge H which cords xx¹ can be tied or hooked
to the handles of the bicycle or other convenient part of motor car, boat etc.

page_text: The shade is supported by a vertical upright S to the top of which it is attached
by the aforesaid hinge I by the flap E which so revolves as to allow the shade
when the cords (o, c, c¹) are unattached to pass backwards & flap down so as to
lic parallel or nearly so to the support S thus moving through an angle or arc
of 270° as shown in Fig. VI where for clearness the flap D of the hinge & the
rod MH has not been shown.
The support S is kept in position by a socket P into which it fits tightly &
which in turn is attached by bars & clamps as required, but in the case of a
lady's bicycle this arrangement is employed viz. bar to pass into the horizontal
bar that carries the saddle if that be hollow & there wedged with wooden pegs &
two other bars 2 & 3 Fig. I clamped to the main back portion of the frame, the
bars 1, 2, 3 are so attached to the clamps in the case of 2 & 3 and to the socket l'
itself in the case of all of them 1, 2, 3 by bolts & nuts that it is not necessary
for the bars 12 & 3 to be horizontal of necessity, the angle of difference being
obtained by a movement of the bar on the bolt either at the clamp or socket end
or both thus enabling the socket P to be fitted to different machines.
Further the bars 2 & 3 are further supported by being fitted into a pyramidal
shaped wooden block which fits by virtue of its shape between the two bars of the
bicycle attached to the axis of the back wheel and held there by clamps 5, 5%
Fig. V. [When closed the shade can be carried in the case of a bicycle as shown
in Fig. VII a cover as of an umbrella being placed over it if so desired.]
The hinge Fig. II shows a diagramatic sketch of it. It consists of a box
shown in Fig. IV in section (transverse in vertical plane). This box is three
sided and might better be called a trough in it fits the rod Y H which has a
screw holding it from the side B or some other attachment. The end of the
side B in the direction of H has hinged to it the flap E and it is by this arrange-
ment that the motion through an arc of 270° is attained the side E being riveted
to the support S there being a sufficiency of E left above the end of the support S
to allow of the box portion of the hinge i.e. the edges of the sides C, C and
the contained rod Y H, to abutt on the top of the support S. Thus the right
angle made by the shade and the support (when the shade is in use) is main-
tained not only by the locking of the hinging of B and E but also by the abutting
of the rod YH etc. on the level top of the support S as shown in Fig. VI.
The sides of the trough C & C shown in Fig. IV have hinged to them at their
ends adjacent to the hinge between B & E the flaps D & A respectively. viz.;
1 hinged to C and A to C¹. On the outside of the flaps D and A are attached the
rods MH and N H. Therefore when closed the rods MH, Y H, and N H are
all parallel and on opening the rods NH and M H can only be separated so
far as the material which forms the shade will allow, this material is stretched
tight by placing the cross bar Z in position & thus a fairly rigid horizontal
surface is obtained Fig. III shows the hinge as seen from above with the flap E
placed in the same plane as the side B. A fringe as shown in Fig. I can be
allowed to hang from the edges of the material forming the shade.
As seen in figure the shade is quadrilateral Y H being a diagonal and therefore
longer than NH or M H which two are of equal length.
The size of the apparatus varies with its use as also do the materials used in
its construction. But a convenient size for a bicycle is to have the support S about
4 or 5 feet long and made of bamboo about 1% inches in diameter at its lower
end and of an inch at its upper.
The hinge is suitable if made of brass and the sides of the trough about two
inches long with corresponding side flaps D & A and the flap E about 2 inches
in dength. While in thickness the brass for this sized hinge would be about
6 parts of an inch, and the width of the trough about
depth the same.
The rods N H, MH, YH should be of light cane or
inch in diameter at its thickest end viz. the hinge end.
The socket & clamps of thin sheet steel or iron the bars
parts of an inch and
bamboo parts of an
Cross bar similar.
should be made of half

page_text: inch bars of steel or iron about part of an inch thick and 6 to 9 or 12 inches
long.
The above figures & materials are only given as a guide and not as essential
parts of the invention.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is:-
1. The hinge obtaining the motion of the two side rods to or from the middle
rod, and also the motion of the middle rod and with it the side rods on the vertical
support and its abutting on support (S).
2. The shade as supported by three rods and a cross bar, the three rods have
somewhat the movement when the shade is attached of a duck's foot horizontally.
3. The attachment in the special case of a ladies bicycle by means of bars
clamps & socket fastened together by nuts & bolts in such a way as to move
on one another and so adapt itself to any machine, and further the wedging by
wooden pegs of one of the bars in the seat pin when that is hollow.
