WILLIAM LLOYD WISE, of 7, Whitehall Place, in the City of Westminster.
'IMPROVEMENTS IN THE MANUFACTURE OF UMBRELLAS AND PARASOLS." (A
communication from abroad by Monsieur Blahat, of Paris, in the Republic of
Prance.)
The Invention communicated to me as aforesaid is described by my foreign.
correspondent with reference to the accompanying Sheet of Drawings as follows
(that is to say) :—
"The object of my improvements is that an umbrella or parasol when once
closed shall remain so without the aid of any fastening ring or collecting cap
whatever, and at the same time that the mounting of the ribs and struts round the
stick shall be simpler and more effective.
"
"Fig. 1 shews the frame of an umbrella or parasol spread out; Fig. 2 gives a
representation on a larger scale of one of the means which I employ for securing
the automatic closing of the umbrella; Fig. 3 shews the same detail as Fig. 2, but
in this case the umbrella is closed; Fig. 4 is a vertical section of the "mount on
my system, which serves for the mounting or uniting of the upper portions of the
ribs; Fig. 5 is an elevation of the slider on my system which connects together the
lower parts of the struts. Immediately below this view is Fig. 5ter, a plan of the
slider; Fig. 5bis shews the form of the ends of the ribs, and of the lower ends of
the struts.
"Figs. 6 and 7 shew the former closed and the second open, the same method of
articulation as Figs. 2 and 3, but with the addition of a guide which keeps the rib
in the same plane with its corresponding strut, and prevents any difficulty (catching
or hanging) in opening, as well as any twisting.
"Figs. 8 and 8 shew another method of keeping the rib and strut firmly jointed
to one another, and Figs. 10, 11, 12, and 13, represent in cross section slight
variations of the same system. In the same way Figs. 14, 15, and 16, shew in
elevation, side view, and plan, a new method of jointed connection between the rib
and strut, so that when once closed the umbrella remains in that position.
"Lastly. Figs. 17 and 18 show, the former in elevation and section, and the
latter in plan, the arrangement of a slider similar to that in Fig. 5, but provided in

page_text: To sum up,
"I claim as my Invention,-
1st. The arrangement of my slider in two parts, and in which are united with
free articulation, but without the aid of iron wire, the lower ends of the struts, as
above described and as shewn by Figs 5, 5bis, and 5ter,
2nd. The arrangement of my system of slider, but provided with a spring for
keeping the umbrella or parasol already closed by hand in that position as shewn
by Figs. 17 and 18.

3rd. The arrangements serving to maintain the closing, already effected by the
hand, of umbrellas and parasols, the said arrangements being applied near the
common articulation of the ribs and struts, as above described, and as represented
by Figs. 2, 3, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, and 16, respectively.
I would remark that the spring arrangement of Figs. 17 and 18 may be applied
by itself for keeping the umbrella closed, or in combination with any one of the
other arrangements shewn near the joint G."
