PROVISIONAL SPECIFICATION.
Improvements in Umbrellas, Parasols, and the like.
I, LEO JONAS, Merchant, of Schmidt Strasse 74 Berlin, Germany, do hereby
declare the nature of my invention to be as follows:-
My present invention relates to that class of umbrellas covered in my Patent
No. 14600 of Aug. 12th 1892 and consists in a simplification of the device for
opening umbrellas as therein described.
In my present invention the ribs to which the silk or other material is attached
are pivotally connected to a hollow crown encircling the umbrella stick which is
also hollow. The sliding ring to which the stretchers are attached is guided by a
pin in a slot in the upper part of the umbrella stick and operated to open and close
the umbrella by means of a lever pivotally arranged in the stick close to the
handle said lever being connected to the sliding ring of the stretchers by means
of a rod extending up to the said ring inside the hollow stick.
On operating the lever aforesaid to close the umbrella the sliding ring of the
stretchers is pushed up the stick and into the hollow crown of the ribs, said crown
having slots in its lower edge for the reception of rods, whilst closing the umbrella.
Either the stretchers must be pivoted to the sliding ring by means of slots or the
ribs must be pivoted to the hollow crown by means of slots to allow the requisite.
play of the parts on their pivots when opening and closing the umbrella. A
suitable device may be employed to retain the operating lever in either of its end.

COMPLETE SPECIFICATION.
Improve nents in Umbrellas, Parasols, and the like.
1, LEO JONAS, Merchant of Schmidt Strasse 7 Berlin, Germany, do hereby
declare the nature of my invention and in what manner the same is performed
to be particularly described and ascertained in and by the following statement:
-
My present invention relates to that class of umbrellas covered by my Patent
No. 14600 of Aug. 12th 1892 and consists in a simplification of the device for
opening umbrellas as therein described.
In my present invention the ribs of the umbrella are pivotally connected to a
crown-shaped top notch, fast on a hollow unbrella stick. The runner to which
the spanner rods are attached is guided by a pin in a slot in the upper part of the
stick and is operated to open or close the umbrella from a lever pivotally mounted
in the lower end of the stick close to the handle by means of a connecting rod,
connecting runner and lever aforesaid.
On operating the lever to close the umbrella the runner is pushed up the stick
and enters the hollow top notch which latter is provided with slots in its lower
edge for the reception of the spanner rods during the operation of closing, otherwise
the same would strike against the lower edge of the hollow top notch and prevent
the umbrella from being properly closed. The spanner rods should be pivoted
to the runner by means of slots or the ribs should be arranged to move in slots
on their pivots in the hollow top notch, so as to allow the requisite play of the
parts on their pivots in opening and closing the umbrella.

page_text: Suitable means are also provided to retain the operating lever in its end
positions.
In order to make this Specification more easily intelligible reference is had to
the accompanying drawing in which similar letters of reference denote similar
parts throughout the several views.
Fig. 1 is a vertical section through the top notch, runner and upper part of the
stick showing the ribs and spanner rods broken off, the umbrella being supposed to
be open.
Fig. 2 shows a section through the top notch, the umbrella being closed.
Fig. 3 is a section of the lower part of the stick showing the operating lever.
B is the hollow crown-shaped top notch, having lugs B' for the pivots of the
ribs A and slots B' in its lower edge for the reception of the spanner rods c during
the operation of closing or opening the umbrella.
The spanner rods c are attached to the runner a which latter is guided by means
of a pin d in a slot din the upper part of the stick. To the pin d―is attached a
connecting rod & which passes down the hollow stick 6 and is connected up to the
arm of the operating lever w by means of a link v. The operating lever wis
pivoted in the stick close to the handle and its arms are free to move in slots b¹³
in the said stick. The arm w¹ of the said lever is provided with a projection or
nose adapted to catch under a spring or catch at the upper end ¹ of the slot b₁
and thus retain the lever in position when the umbrella is open. When the
umbrella is closed the lever is retained in the opposite position by means of a
hook y under which it may be conveniently passed, said hook y being attached to
the stick.
The ribs A are connected to their pivots in B by means of slots A¹ as shown in
Figs. 1 and 2 in order to allow the necessary play in opening and closing the
umbrella.
The same object may however be attained by providing the spanner rods c with
slots embracing the pivots of the runner a.
The operation of the device is as follows:-
On raising the end of the lever w the runner a will be forced up into the
hollow top notch B as shown in Fig. 2 and the umbrella thus closed. The
movement of the lever in the opposite direction opens the umbrella by pulling the
runner a down and stretching the ribs A.
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 :-
1. In umbrellas the combination of the hollow top notch B having slots B¹
and pivotal attachments for the ribs A, having slots A¹ the runner a guided by
means of pin d in slots d' of the umbrella stick, an operating device for said runner
situated near the handle of the said umbrella and connected to said runner by
suitable means substantially as described and shown and for the purpose specified.
2: In combination with an umbrella having hollow crown shaped top notch,
runner a to pass into said top notch as specified, ribs A pivotally attached to
top notch and spanner rods c attached to runner a as set forth, an operating device
for said runner consisting of lever w pivotally attached to the stick near the
handle, said lever having arms w¹ w³ moving in slots 6' 6 of the hollow stick, a
connecting rod d within the tubular stick and a connecting link v as also means for
retaining said lever in either end position substantially as described and shown
and for the purpose specified.
