PROVISIONAL SPECIFICATION.
Improvements in Frames for Umbrellas and other like articles.
We, PIERRE JULES CHARAGEAT and EMILE FRANÇOIS JOSEPH CHARAGEAT
both of 1 Boulevard St. Denis, Paris, France, Manufacturers, do hereby declare the
nature of this invention to be as follows:-
Our invention has reference to frames for umbrellas and other like articles and
more particularly to those which automatically keep the umbrella open by means
of special fittings or connections of the stretchers to the ribs. The object of the im-
provements is to provide for an automatic closing of the umbrella and this is effected
by a novel joint or connection between the stretchers and the ribs, a small friction
roller being provided on which a spring attached to the stretcher bears so that the
action of the stretcher is easier and more regular even after the umbrella has been
in use for a long time.
In carrying out our invention we prefer to use "Paragon" ribs and stretchers,
that is to say, ribs and stretchers of U form in section, but the invention can be
adapted to other sections. The lodgment for the end of the stretcher is a piece of
metal passed round the rib and secured in the concave part; two wings or checks
project from this piece to receive the stretcher end. The wings also support the-
roller and against this bears the spring for the opening and closing movements
fitted within the stretcher. By the displacement or movement of the stretcher
during the closing or opening the spring has a sort of excentric motion and it then
acts vigorously so as to impart a rapid and automatic closing or opening movement
to the stretcher. The closing is not only automatic but complete, that is to say,
the ends of the ribs bear against the runner without any extraneous pressure. The
runner may however be arranged so as not to move so far as the ends of the closed
ribs, and in this case the ribs are made of peculiar configuration to leave space
for the hand to be inserted to reach the runner. In this peculiar configuration
the rib is curved slightly inwards near the point of connection with the stretcher
and again curved outwards between the inward curve and the end, the actual end
being however curved inwards so as to come against the stick when the umbrella
is closed and secured by a band or fastening.
The arrangement hereinbefore described of the connections between the ribs
and the stretchers can be reversed, that is to say, the roller can be placed on the
end of the stretcher instead of in the lodgment on the rib.

We PIERRE JULES CHARAGEAT and EMILE FRANÇOIS JOSEPH CHARAGEAT
both of 1 Boulevard St. Denis, Paris, France, Manufacturers, 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 :-
Our invention has reference to frames for umbrellas and other like articles and
more particularly to those which automatically keep the umbrella open by means
of special fittings or connections of the stretchers to the ribs. The object of the
improvements is to provide for an automatic closing of the umbrella and this is

Figures 1, 2 and 3 of the accompanying drawings represent an umbrella rib
and stretcher with our invention applied thereto. We prefer to use "Paragon
ribs and stretchers, that is to say ribs and stretchers of U-form in section, but the
invention can be adapted to other sections. a is the Paragon rib. The lodgment
for the end of the stretcher is a piece of metal 6 passed round the rib and secured
in the concave part; two wings or cheeks ec project from this piece to receive the
end of the stretcher d. The wings ce also support the roller and against this
bears the spring for the opening and closing movements fitted within the
stretcher. By the displacement or movement of the stretcher during the
closing or opening the spring g has a sort of excentric motion, as will be under-
stood on reference to Figure 3, and it then acts vigorously so as to impart a rapid
and automatic closing or opening movement to the stretcher. Figures 4 and 5 are
diagrammatic views of the umbrella frame. In Figure 4 the frame is shown open
and firmly held owing to the position of the stretchers which have passed the
horizontal line. In Figure 5 it is closed. This closing is not only automatic but
complete, that is to say the ends of the ribs bear against the runner without any
extraneous pressure. This is also seen in Figure 6 which represents the frame
covered with silk or other material; although the elastic band is unfastened the
ribs remain closed and bear against the runner. The runner may, however, be
arranged as seen in Figure 7, so as not to move so far as the ends of the closed
ribs, and in this case the ribs are made of peculiar configuration or form to leave
space for the hand to be inserted to reach the runner. This peculiar configuration
or form is represented in Figure 8; the rib is curved slightly inwards at near the
point of connection with the stretcher and again curved outwards as shown at i
between the inward curve and the end, the actual end being however curved
inwards so as to come against the stick when the umbrella is closed and secured by
a band or fastening.
The arrangement hereinbefore described of the connections between the ribs and
the stretchers can be reversed, that is to say the roller can be placed on the end of
the stretcher instead of in the lodgment on the rib.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim in respect of frames for umbrellas and other like articles is :-
1. The novel joint or connection between the stretchers and the ribs, substantially
as hereinbefore described and represented in the accompanying drawings for the
purpose set forth.
2. The peculiar configuration or form of rib hereinbefore described and repre-
sented in Figure 8 for the purpose set forth.
