Improvements in Means for Securing the Covers of Umbrellas and
Parasols to the Outer Ends or Tips of the Ribs.
We, FREDRIK STANG UCHERMANN, of Christiansand, Norway, Officer of
Customs, and JOHN THORESEN ODEGARD, Room No. 618 New York Life
Building, Minneapolis Minnesota, United States of America, Banker, 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:-
The usual method of securing the covers to the tips is by sewing or wrapping
the same with thread, a hole or aperture being formed in the rib near the outer end
through which the thread is passed to prevent it from slipping. This is a very
insecure method of fastening, as the thread is extremely liable to break and the
cover become detached from the rib.
The object of our invention is to provide improved metallic fastening devices
whereby the employment of thread is obviated and the cover attached to the ribs in
a very secure and permanent manner.
The invention consists in the novel construction and combination of parts herein-
after fully described and claimed.
In the accompanying drawing
--
Figure 1 is a view of a portion of an umbrella cover and rib connected together
according to our invention;
Figure 2 is a similar view looking from the opposite side;
Figure 3 is a similar view of a modification;
Figure 4 is a view of the securing plate before being bent over to clamp the
cover to the rib tip;
Figure 5 is a view of the ring or loop engaging with the rib and clamping or
securing plate;
Figure 6 shows a modification in the manner of forming the eye or loop in
the ribs.
In the said drawing, the reference numeral 1 denotes an umbrella or parasol rib
provided with an eye or aperture 2. This eye may be formed by punching or
drilling, or it may be formed by bifurcating the end of the rib and twisting said
ends together, as shown in Figures 3 and 6. The numeral 3 designates a clamp
consisting of a piece of sheet-metal having its sides bevelled from each end towards
the center, and bent over upon itself forming two clamping-plates 3 and 3b, and a
loop 3, one of said plates being provided with two or more tongues 4, and with a
series of teeth or serrations 5. The numeral 6 denotes a ring or loop formed of
wire, which is adapted to be passed through the eye in the rib and the loop 3°.
The method or manner of securing the cover to the ribs is as follows: The
umbrella or parasol may be of any ordinary construction, the gores comprising the
cover being sewed together as usual, with the seams running along the ribs.
The edge of the cover is inserted between the clamping plates 3* and 3b, which
are then pressed firmly together by a pair of nippers or pliers, so as to press the
teeth into the cloth. The arms are then bent over the opposite plates so as to
securely clamp the plates together. The ring 6 is then inserted in the eye in the
rib and in the loop 3° and its ends pressed together, whereby the clamp is securely
attached to the rib.
From the above it will be seen that a very simple, inexpensive, and efficient
fastening device is provided by which the cover can be easily and readily secured
to the rib voints.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :
1. In an umbrella or parasol, the combination with the ribs and cover, of the
metallic securing plates connected with the ribs and the cover, substantially as and
for the purpose described.
2. In an umbrella or parasol, the combination with the cover and the ribs having
eyes therein, of the clamp consisting of a piece of metal bent over upon itself
forming clamping plates and loops, and provided with the teeth and over-lapping
tongues, and the rings adapted to engage with said loops and the eyes in the rib,
substantially as described.
