Improvements in Rings or Locks for Holding the Rib-points of
Umbrellas.
I, WILHELM JEDECK, of 5 Seharrn Strasse Berlin, Germany, Umbrella-stick
Manufacturer, 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 the rings or locks used for holding in place, when an
umbrella is closed, the projecting points of the ribs.
In this invention, instead of using a rubber or metal ring, as usual, I use semi-
circular hoops or bands, the ends of which are secured within a casing, fitted on the
umbrella stick, and are subjected to the action of a spring or springs, in such manner
that, when the hoops are turned down to the closed or locked position, they are
held firmly in place, and also, when they are turned up or opened, they are likewise
held firmly in position. The hoops may be moved separately from one another, or
they may be so made as to work together conjointly.
And in order that my said invention may be properly understood, 1 have here-
unto appended two explanatory sheets of drawings, whereon:-
Figs. 1 to 12 show a form of lock, in which both parts or hoops have to be moved
separately.
Fig. 1 is a side elevation, showing the lock as it appears, when closed.
Fig. 2 is a side elevation, showing the lock open.
Fig. 3 is a cross section on the line -, Fig. 1.
Fig. 4 is a part vertical section on the line y-y, Fig. 3.
Figs. 5 and 6 show the action of the spring.
Figs. 7 and 8 are sectional and plan views of a ferrule, which is secured to the
umbrella stick and on which the casing d is fitted.
Figs. 9, 10, 11 and 12 are different views of the hoops of the lock.
Figs. 13 and 14 show an arrangement in which the one hoop or part moves the
other.
Figs. 15 and 16 show a different method of effecting the same thing.
Referring to the drawings, whereon the same reference letters, wherever repeated,
indicate similar or like parts :-
The device, as shown at Figs. 1 to 12, consists of two semi-circular rings or
hoops of metal a, a', having arms b. projecting at right angles. At the ends of
the arms b, b', are studs c, c, which are passed through holes in the casing d, which
latter is secured on the ferrule g. At the ends of the studs c, c', are square buttons
or heads h, h. These buttons bear on a bent ring-shaped-plate-spring e, in such a
manner that, when the hoops a, a', are moved to either the closed or open position,
they are held securely in place. Figs. 5 and 6 show the action of the spring e,
when the hoops are moved. The ferrule g has lugs i on which the casing d rests,
and by which it is held in place.
The parts g and d are fitted together by first pushing the ferrule g up through
the opening in the bottom k of the casing d, and out through its top, and by then
bending over or flanging the top of the ferrule, as shown at Fig. 4.
As will be seen, when the hoops a, a', are being opened up, the buttons h, h¹,
press down the spring, as shown at Fig. 6, until the hoops are turned to the full
open position, when the spring e springs back again to its original position, and so
locks the hoops. The same action takes place when the hoops are being closed.
In the hereinbefore described arrangement, it is necessary, in order to lock or
unlock the rib-points, to actuate each hoop separately. In Figs. 13 and 14,
however, an arrangement is shown, wherein the movement of one hoop a', actuates,

page_text: synchronously, the other hoop a. To effect this, the button ¹ of the hoop a' is
made with two teeth I, whilst the button h of the hoop a, has a notch or recess, into
which the teeth can enter. If the hoop a' is moved upward or downward, one of
the teeth, in each case, catches in the notch or recess and so synchronously
actuates the hoop a. Fig. 13 shows the hoops in the locked position, whilst Fig. 14
shows them in the open position.
In the arrangement, Figs. 13 and 14, the hoop a', i.e., the hoop with the teeth 1,
must, in all cases, be moved first, but, in Figs. 15 and 16, a different arrangement
is shown, wherein either hoop may be moved, and, when moved, will actuate the
other. The arrangement simply consists in making both buttons h, h, with a
number of cogs, which mesh into one another, so that, when the one hoop is moved,
the other is moved also.
Instead of pivoting the hoops in a casing d, they may be pivoted in the stick.
. 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. The improved construction of rib-point-lock for umbrellas, constructed and
operating substantially as hereinbefore described, with reference to Figs. 1 to 12
of the drawings annexed.
2. The modified construction of rib-point-lock, substantially as hereinbefore
described with reference to Figs. 13 and 14 of the drawings annexed.
3. The modified construction of rib-point-lock, substantially as hereinbefore
described with reference to Figs. 15 and 16 of the drawings annexed.
4. The combination with the hoops a, a', having buttons, or equivalent, h, h', of
the casing d and 'the locking spring or springs e, fitted in the casing, substantially
as herein before described and shown on the drawings annexed.
Dated this 14th day of November 1892.
