Patent Agent. "IMPROVEMENTS IN UMBRELLAS AND SUNSHADES." [A communi-
cation from abroad by François Marie Constantin Farradescho, of Paris, France.]
This Invention relates to improvements in umbrellas and sunshades, and consists,
first, in a construction of spring joint uniting the ribs to the stretchers, whereby
the stretchers and ribs are held snugly against the stick when the umbrella is
closed,
The Invention is illustrated by way of example in the accompanying Drawing,
in which Figure 1 represents the umbrella frame in the open position; Figure 2
shows a side view of the joint between the ribs and stretchers in the closed
position; Figuro 3 is a front view of same; Figure 4 an elevation and Figure 5 a
horizontal section on line 1-2, Figure 4, the relative positions of the stretcher and
rib being such as they would occupy when the umbrella is half opened; Figure 6
is a part sectional elevation showing the mode of jointing the stretchers to the
runner; Figure 7, an inside view of same; Figure 8, a cross section of the upper
part of the runner; Figure 9, a plan of same; and Figure 10, an elevation of a tube
for retaining the stretchers in the groove of the runner.
The same letters of reference indicate the same parts in all the Figures.
a, a, are the ribs and b the stretchers. Each stretcher has a tubular part o near
the end, formed by bending the metal, in which are received two flat springs d
placed back to back and splayed outwards at their ends. They are secured by a
pin e passing through them and through the ears of a clip fembracing the rib a.
The splayed ends of the springs d are pressed together on entering between the
ears f, as shown in Figures 4 and 5, but expand on emerging from the same, and

page_text: thus tend to bring the stretchers parallel to the ribs, and thus hold them snugly
against the stick, as shown in Figures 2 and 3.
The joint of the stretchers to the runner i is formed by a cross ping received in
an internal groove in the runner notch, and retained therein by an inner tube k
having a shoulder at its upper end, abutting upon a shoulder m of the runner.
The tube is split at the lower end, as at n, n, to mako it fit spring tight in tho
runner
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Alexander Melville Clark in the Great Seal Patent Office on the
14th December 1880.
ALEXANDER MELVILLE CLARK, of 53, Chancery Lane, in the County of Middlesex,
Patent Agent. "IMPROVEMENTS IN UMBRELLAS AND SUNSHADES,” A communi-
cation from abroad by François Marie Constantin Farradesche, of Paris, Franco.
This Invention relates to improvements in umbrellas and sunshades, and consists,
first, in a construction of spring joint uniting the ribs to the stretchers, whereby the
stretchers and ribs are held snugly against the stick when the umbrella is closed,
and, secondly, to an improved joint uniting the stretchers to the runner.
The Invention is illustrated by way of example in the accompanying Drawing,
in which Figure 1 represents the umbrella frame in the open or expanded position;
Figure 2 represents a side view and Figure 3 an edge view of the joint uniting the
ribs and stretchers in the closed position of the umbrella; Figure 4 represents an
elevation, and Figure 5 a section on line 1-2, Figure 4, of the same joint, tho
relative positions of the stretcher and rib being such as they would occupy when
the umbrella is half opened; Figure 6 is a. part sectional elevation showing the
mode of jointing the stretchers to the runner; Figure 7 represents an inside view
of the same joint; Figure 8 represents a cross section and Figure 9 a plan of the
grooved and notched part of the runner; and Figure 10, an elevation of a tube for
retaining the stretchers and joint pins in the groove of the runner notch. The
same letters of reference indicate the same parts in all the Figures.
a, a, are the ribs and 6 the stretchers. Each stretcher has a tubular part c near
the end, formed by bending up the metal, and terminating in a fork, which is
jointed by a pin è to the cars of a clip that ombraces the rib a.
Within the
part c are fixed two flat springs d, placed back to back and splayed outwards at
their ends. The springs are held in place by the same pin e, which passes through
them and through the ears of the clip f. The splayed ends of the springs d are
pressed together on entering between the cars f, as shown in Figures 4 and 5, but
expand on emerging from the same in the act of closing the umbrella, and thus
tend to bring the stretchers parallel to the ribs, and hold them snugly against the
stick, as shown in Figures 2 and 3.

page_text: The improved joint for uniting each stretcher to the runner i is formed by a
cross pin passing through the end of the stretcher, and received in an internal
groove in the runner notch, and retained therein by an inner tube having a
shoulder at its upper end abutting upon a shoulder m of the runner. The tube k
is split at the lower end, as at n, n, to make it fit spring tight in the runner.
The form and dimensions of the different parts may be varied as found desirable
in practice.
Having described the nature of the said Invention, and the manner of performing
the same, I declare that what I claim as the Invention to be protected by the
herein before in part recited Letters Patent is,-
1st. In an umbrella or sunshade, the combination with the joint uniting the ribs
and stretchers of springs applied and acting in such manner as to press the ribs
and stretchers against the stick when the umbrella is closed, substantially as
shown and described.
2nd. The internally grooved runner notch in combination with an inner split
tube for retaining the joint pins of the stretchers, and uniting the same to the
runner, substantially as shown and described.
In witness whereof, I, the said Alexander Melville Clark, have hereunto set
my hand and seal, this Fourteenth day of December, in the year of our
Lord One thousand eight hundred and eighty.
