PROVISIONAL SPECIFICATION.
Improvements in Umbrellas, Parasols, and like Sunshades.
I, JOHN FORBES, of 11 Harrington Square, in the County of London, Clerk,
do hereby declare the nature of this invention to be as follows:-
My invention relates essentially to an improved arrangement and construction of
the stretchers and runners of umbrellas, parasols and the like sunshades whereby
the ribs may be easily secured in a compact form close to the stick when the
unbrella or parasol is closed.
For the purposes of my invention, I arrange the ribs and stretchers in the
ordinary manner, the length of the latter being such that the runner to which they
are attached is carried beyond the ends of the ribs when the umbrella or parasol is
closed and the flanged end of a ring mounted upon said runner brought into position
to embrace the ends of all the ribs and so hold them in a compact form close to
the stick.
The interior of this ring and the exterior of the runner are screw threaded so that
by revolving the former in one direction its flanged end is brought into a position
to embrace the ends of the ribs whilst by revolving it in the opposite direction it is
carried out of contact with the ribs.
To prevent the runner turning with the ring mounted upon it a projection is
formed in the interior of the runner and projects into a longitudinal slot in the stick
or a slot in the runner arranged to slide on button or projections on the stick or the
like means provided for this purpose.

I, JOHN FORBES, of 11 Harrington Square, in the County of London, Clerk,
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:―
My invention relates essentially to an improved combined arrangement and
construction of the stretchers and runners of umbrellas, parasols and the like
sunshades whereby the ribs may be easily secured in a compact form close to the
stick when the umbrella is closed.
For the purposes of my invention, I arrange the ribs and stretchers in the
ordinary manner, the length of the latter however being such that the runner to
which they are attached is carried beyond the ends of the ribs when the umbrella
said runner
or parasol is closed so that the end of a ring or collar mounted upon
may be brought into position to embrace the ends of all the ribs and so hold them
in a compact form close to the stick.

page_text: The internal surface of this ring or collar and the external surface of the runner
have projecting screw threads formed on them so that by revolving said ring or
collar in one direction its end is brought into a position to embrace the ends of the
ribs, whilst by revolving it in the opposite direction it is carried out of contact with
the ends of said ribs.
The ring or collar is prevented from travelling too far in either direction on the
runner by a flange projecting from its internal surface which flange, when said ring
or collar is revolved so as to cause it to travel in the direction that its end is
brought to embrace the ends of the ribs will eventually strike against the ends of
said ribs whilst when the collar is caused to travel in the opposite direction the
flange eventually strikes the screw thread on the runner over which it cannot
pass.
And in order that my invention may be more fully understood and carried into
practice I will now proceed to describe the same with reference to the accompaying
drawing, which shows an elevation partly in section of a sufficient portion of au
umbrella to illustrate the practical application of my invention.
The stretcher a and the ribs b are arranged in the ordinary manner, the length of
the former being, however, such that when the umbrella is closed the runner c is
carried beyond the ends of the ribs & so that a ring d screwing on to the runner c may
be brought into such a position by revolving it that its end d' embraces the ends of
the ribs and so holds them in a compact position close to the stick e until the ring d
is revolved in the opposite direction when it is carried out of contact with the ends
of the ribs and consequently releases these latter. The external surface of the
runner and the internal surface of the collar are preferably only screw threaded for
a short distance, and said screw threads arranged to project as shown. The ring or
collar d is prevented from travelling too far in either direction on the runner c by a
flange projecting from its internal surface which flange when said collar a is
caused to travel in the direction that its end d' will embrace the ends of the ribs b
ultimately strikes against the ends of said ribs so stopping any further movement of
the collar in that direction whilst when the collar is revolved in the opposite
direction said flange eventually strikes against the projecting screw thread on the
runner over which it cannot pass.
The runner may be prevented from revolving by one or more projections
extending from its interior into grooves in the stick on which it slides.
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 :-
The improved means of securing the ribs of umbrellas, parasols and the like
sunshades, in a closed position consisting of a ring or collar d screwing on to
runner c and having a flange projecting from its inner surface arranged and
operating in the manner described and illustrated in the accompanying drawing.
