PROVISIONAL SPECIFICATION.
Improvements in and relating to Umbrellas and Parasols.
I, PAUL GEORG KÜHSEL, of 13 Fischmarkt in the City of Hamburg, in the
Empire of Germany, Merchant, do hereby declare the nature of this invention to
be as follows:-
My invention relates to improvements in umbrellas and parasols and the object
of the same is to provide means for causing the opening and closing of the umbrella
or parasol by shortening or lengthening the stick of the same.
For this purpose the stick to which the handle and the frame of the umbrella is
attached is composed of two parts, the upper or handle part being provided at its
lower end with a screw-threaded stem, which engages with corresponding female
thread in the lower part carrying the ribs suspending socket and the ferrule of the
umbrella-stick. This latter part is of tubular form, in order to receive the said
screw-threaded stem attached to the upper or handle-part of the stick, and it is
provided on its outer surface with a screw-thread of opposite direction and different
pitch to that of the said screw threaded stem and adapted as a guide for the
runner or sleeve to which the usual braces are pivoted.
In contradistinction to the usual manner of attaching the braces to the ribs of
the frame both are rigidly connected together, so that on opening and closing the
umbrella the braces will partake of the deflection of the ribs and the runner or
sleeve will approach the socket on the ferrule end, when the umbrellà is closed,
and it will approach the handle while the umbrella is opened. For this purpose
the said runner or sleeve is provided with female thread engaging with the thread
on the tubular ferrule end of the stick and it is properly extended so as to form a
guide for the upper or handle part of the umbrella-stick.
It will be understood from the foregoing, that on account of the lower tubular
part of the stick engaging on the one hand with the said screw-threaded stem of
the upper or handle part of the stick and on the other hand with the runner or
sleeve of the umbrella frame through the medium of a screw-thread of different
pitch and opposite direction to those of the said screw-threaded stem and as in both
cases a thread of very coarse pitch is employed, on exerting an axial pressure upon
the handle the runner will approach the same and thereby cause the braces and the
ribs of the frame connected thereto to unfold and thereby open the umbrella, in
which position the frame is held by the spring action of the braces. On extracting
the upper part of the stick from the runner or sleeve the braces and ribs of the
frame will fold close together thereby closing the umbrella or parasol.
The rigid connection of the braces to the ribs of the umbrella frame will prevent
the latter from tilting over in the wrong direction in case of heavy wind or
storm.

Improvements in and relating to Umbrellas and Parasols.
I, PAUL GEORG KÜHSEL, of 13, Fischmarkt in the City of Hamburg, Germany,
Merchant, 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 to improvements in umbrellas and parasols and the object of
the same is to provide means for causing the opening and closing of the umbrella or
parasol by shortening or lengthening the stick of the same.
In the accompanying drawing
Figure 1 is an elevation of the said umbrella or parasol showing the same
closed.
Figure 2 is a like view of the same but shown open.
Figure 3 is an enlarged view partly in section showing the umbrella or parasol
closed.
Figure 4 is a like view but the said umbrella or parasol is shown open; and
Figure 5 is an enlarged view in elevation of the upper and lower parts of the
stick of the umbrella or parasol with the ribs removed the same being shown in all
cases without the cover for the sake of clearness.
The stick to which the handle and the frame of the umbrella is attached is
composed of two parts, the lower or handle-part a being provided at its upper end
with a screw threaded stem d, which engages with a corresponding female thread
in the upper part carrying the ribs the suspending socket g', and the ferrule f¹
of the umbrella-stick. This latter part is of tubular form, in order to receive
the said screw-threaded stem d attached to the lower or handle-part
a of the
stick, and it is provided on its outer surface with a screw-thread of opposite direction
and different pitch to that of the said screw-threaded stem d and adapted as a
guide for the runner or sleeve b to which the usual braces c are pivotted.
In contradistinction to the usual manner of attaching the braces c to the ribs g
of the frame both are rigidly connected together, so that on opening and closing
the umbrella the braces c will partake of the deflection of the ribs g and the runner
or sleeve will approach the socket 9' on the ferrule end, when the umbrella is
closed, and it will approach the handle while the umbrella is being opened. For
this purpose the said runner or sleeve b is provided with a female thread engaging
with the thread on the tubular ferrule end of the stick and it is properly extended
so as to form a guide for the lower or handle part of the umbrella-stick.
It will be understood from the foregoing that on account of the upper or tubular
part of the stick engaging on the one hand with the said screw-threaded
stem d of the lower or handle-part a of the stick and on the other hand with the
runner or sleeve 6 of the umbrella frame through the medium of a screw-thread of
different pitch and opposite direction to those of the said screw threaded stem d
and as in both cases a thread of very coarse pitch is employed, on exerting an
axial pressure upon the handle the runner 6 will approach the same and thereby
cause the braces c and the ribs of the frame connected thereto to unfold and
thereby open the umbrella, in which position the frame is held by the spring action
of the braces c. On withdrawing the lower part a of the stick from the runner or
sleeve b the braces and ribs of the frame will fold close together, thereby closing
the umbrella or parasol.
The rigid connection of the braces c to the ribs g of the umbrella frame will
prevent the latter from being bent backwards in the wrong direction in case of
heavy wind or storm.
The sleeve b or the stick of the umbrella or parasol may be provided with any
convenient device of known construction in order to secure both in their extreme
positions.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In an umbrella or parasol the combination of the braces c with the sleeve or
runner band of the ribs g of the frame with the threaded ferrule end ƒ guided
within the runner b and the screw threaded stem d connected to the handle part a
of the stick, substantially as and for the purpose specified.
2. In an umbrella or parasol the rigid connection of the elastic braces c to the
ribs
9 of the frame substantially as and for the purpose set forth.
