PROVISIONAL SPECIFICATION.
Improvements in Umbrellas and other like Articles.
I, JEAN BAPTISTE CHASSAING of 1 Boulevard St. Denis, Paris, France, Umbrella
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention has reference to umbrellas and other like articles and consists first
of a novel form of rib in which the seams of the cover are lodged and concealed,
and secondly of a novel attachment of the stretchers to the ribs whereby the stop
or catch at the upper part of the stick can be dispensed with while rivetted joints are
avoided.
Hitherto in covering umbrellas the seams have been attached to the ribs (of any
suitable form) by stitches which have passed around the ribs; this mode is defective
inasmuch as the stitches are liable to cut the cover, and the seam lies at the side of
the rib and is visible from under the umbrella. Now I employ ribs of trough or
gutter form in section the concavity being at the outside of the umbrella. I form in
these ribs at each place where there is to be a stitch two small holes through
which the thread for securing the seam to the frame passes; in this way all
liability to cut or tear the cover is avoided and the seam is concealed in the concavity
of the rib.
On each rib I rivet at a suitable position a piece forming at its lower end a clasp or
book with which the outer end of the stretcher engages; above the clasp or hook the
piece has a shoulder which acts as a stop to the stretcher when it has been pushed up
to the horizontal or open position. Thus the travel of the runner notch is limited
while no catch at the upper part of the stick is required. An automatic fastening
when the umbrella is closed is also obtained by means of the same parts. In a
modification of the rib and stretcher attachment above described the clasp or hook is
prolonged by a rod which passes through the rib and lies in the external concavity
or trough; this rod has a small projection on its inner side which passes through a
hole in the rib and serves as a rivet.

COMPLETE SPECIFICATION.
Improvements in Umbrellas and other like Articles.
I, JEAN BAPTISTE CHASSAING of 1 Boulevard St. Denis, Paris, France, Umbrella
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:-
My invention has reference to umbrellas and other like articles and consists first of
a novel form of rib in which the seams of the cover are lodged and concealed
and secondly of a novel attachment of the stretchers to the ribs whereby the stop
or catch at the upper part of the stick can be dispensed with while rivetted joints are
avoided.
Hitherto in covering umbrellas the seams have been attached to the ribs (of any
suitable form) by stitches which have passed around the ribs; this mode is defective
inasmuch as the cover is liable to get cut at the stitches and the seam lies at the side
of the rib and is visible from under the umbrella. Now I employ ribs of trough or
gutter form in section, such for example as the forms shown at a, Figures 1, 2, 3 and 4,
the concavity being at the outside of the umbrella. I form in these ribs at each place

page_text: where there is to be a stitch two small holes b. through which the thread for securing
the seam to the frame passes; in this way all liability to cut or tear the cover is
avoided and the seam is concealed in the concavity of the rib.
On each rih a I rivet at a suitable position a piece c (see Figures 5, 6, 7 and 8)
forming at its lower end a clasp or hook with which the outer end d of the stretcher f
engages; above the clasp or hook the piece c has a shoulder g which acts as a stop to
the stretcher when it has been pushed up to the nearly horizontal or open position.
Thus the travel of the runner notch is limited while no catch at the upper part of the
stick is required. An automatic fastening when the umbrella is closed is also obtained
by means of the same parts (see Figure 7). In Figure 8 the heel of the outer end d
of the stretcher f is less accentuated; the stretcher is therefore more free, the clasp
or hook of the piece c not moving. In a modification represented in Figures 9, 10,
and 11 of the rib and stretcher attachment above described the clasp or hook of the
piece rivetted as before to the rib a, is prolonged by a rod h which passes
through the rib and lies in the external concavity or trough; this rod has a small
projection on its inner side which passes through a hole in the rib and serves as
a rivet.
i
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 in respect of umbrellas and other like articles is :-
1. The employment of ribs of trough or gutter form in section the concavity being
at the outside of the umbrella, and the securing of the seams of the cover to these
ribs substantially in the manner and for the purpose set forth.
2. The mode or means of attaching the stretchers to the ribs substantially as herein-
before described and represented in Figures 5, 6 and 7.
3. The modified arrangement of rib and stretcher attachment represented in
Figures 9, 10 and 11 and herein before described.
