COMPLETE SPECIFICATION.
Improvements in Umbrellas, Parasols, and Sunshades.
I, EMIL WEIDLICH of 14 Benwell Road Holloway in the County of Middlesex
Manufacturer's Agent 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:-
This invention consists in improvements in Box's umbrella patented 30th September
1884 No. 13,008, the object being to increase its strength and usefulness while
decreasing its bulk. The aforesaid umbrella although a great improvement upon
what had been previously done has certain defects one being that the ribs and
stretchers when the umbrella is folded do not arrange themselves in regular order
each resting in its fluting of the fluted tubular metallic stick. This is chiefly owing
to the form of catch used. Experience has also shown that the tubular metallic shoe
and the means for connecting the ribs to the notch and to the runner are open to
improvements.
The improved umbrella constructed according to this invention is illustrated by
enlarged views on the accompanying drawings.
Figure 1 is a longitudinal section of part of the stick broken off as to length, but
shewing the handle part with runner and lower catch the middle part shewing the
outer stop for the runner and Figure 2 is a longitudinal section of the outer end or
notch and shoe part. Figure 3 is a cross section through the stick with the runner
on viewed from the handle end. Figure 4 is a side view of the runner resting on the
outer spring catch. Figure 5 is a perspective sectional view of a rib and stretcher
when folded into each other. Figure 6 is a side view and Figure 7 a cross section of
the rib and stretcher joint and Figure 8 a plan of same. Figure 9 is a sectional side
view of the runner with stretcher jointed thereto. Figure 10 is a cross section of a
runner looked at from the handle end of the stick. Figure 11 is a sectional view of
modified form of shoe part.
The tubular stick A is made of thin brass, aluminium, bronze, delta metal, or other
similar suitable material of sufficient strength and resilience the fluted shape being
imparted to it by rolling. If it is filled with a core of gutta percha it may be made of
still thinner substance, as the core imparts additional strength and resilience. It is
let into the wooden handle B about two inches or nearly so. The tip cap C with
ferrule D is of usual form.
The runner E is cut from length of tube having the fluted shape imparted to it by
rolling and fits easily but accurately on the stick A. The handle end of the runner is
by preference provided with a strengthening or ornamental fluted flange E¹ either by
pressing up the end by means of a special tool or by soldering on a thin flat ring of
the exact form of the fluted exterior of the runner.
By this means I cause the ribs to lie closely up to the runner embedded as it were in
the flutings thereof; thus decreasing the bulk of the umbrella at this place where the
folded umbrella is comparatively bulky.
F Figures 1 and 4 shews the two runner catches consisting each of the flat cain
shaped part which protruded through a slot on the runner by the spring part F¹ the
end of which after insertion is rivetted to the stick as shewn at F2. It will be
observed that the slot in the runner as well as through the stick is through one of its
ridges so that the catches F do not interfere with the accurate placement of each rib
and stretcher in its particular fluting of stick and runner there being as many flutings
as there are ribs G and stretchers H eight being the usual number. The stretchers H
are rivet jointed to the runner by wiring in the manner shewn in Figure 9 being
brought as close to the stick as possible.

page_text: Referring to Figures 5, 6, 7 and 8 the ribs G are of a rather deep trough shape with
narrow flanges which latter are slightly curved as shewn by the dotted circle and
radius in Figure 5 by this means and by the slight rounding of the flange edges I
prevent the silk or other covering from being cut or injured. The stretcher H is of a
corresponding trough shape but without flanges, the rib G folding in the stretcher H.
The rib is only just deep enough to admit of a rivet to pass through for jointing the
stretcher to the rib, the git I being made rather longer than usual thus making up for
the loss of strength of rib occasioned by the rivet hole and being also firmly and
accurately lapped round the flanges of the rib as shewn at Figure 7 by a special tool.
The stretcher is made forked where it is jointed to the rib and git as shewn in
Figures 6, 7 and 8.
The shoe end K of the stick Figure 2 is of wood screwed on to the wood screw L
which is brazed into the end of the fluted stick A. The shoe end K thus holds the
notch M and the intermediate ferrule N in place. The ribs are jointed to the notch M
by wiring the joints being as close to the stick as possible and as shewn whereby the
important advantage is obtained that the ribs lie entirely in the flutings. The cover of
the umbrella is united to the ferrule M which is grooved for the purpose. The notch M
has a feather and the screw L a corresponding flat. The ferrule N has a feather and
the notch Ma corresponding flat.
Figure 11 shews a modified form of shoe end of stick in which a wire core L brazed
in the fluted stick A is carried right through the wooden shoe end K and all the parts
held together by the screwed shoe O.
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 is
First. The improved construction of umbrella, sunshade or parasol, substantially as
described and shewn.
Second. The combination of springs F with the fluted stick A as described and
shewn.
Third. The improved construction of rib and stretcher joint substantially as described
and shewn.
Fourth. The combination with the fluted stick A of the improved notch and shoe
end substantially as described and shewn.
Dated this 19th day of December 1888.
