Improvements in Collapsible Umbrellas.
I, HUGO HAEGERMANN, of 109, Alte Jacob Strasse, in the City of Berlin, in
the German Empire, Manufacturer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:
The subject of the present invention is a collapsible umbrella, which whilst
having the external appearance of any ordinary umbrella, is of such construction
as to admit of being folded together for the purpose of being placed in the
pocket, in a hand-bag or the like.
The improved umbrella is shown on the accompanying drawing, in which
Fig. 1 is an elevation of the frame extended for use, the lower rib on the right
hand side being shown turned back upon the upper one.
Fig. 2 shows the umbrella frame in collapsed condition, ready for being put
in the pocket or stowed in a bag.
Figs. 2 to 9 are detail views to be hereinafter referred to.
The stick of the umbrella is composed preferably of three telescopic metal
tubes a, b, c, and the sleeve e, sliding upon them in the ordinary manner, is pro-
vided with a spring snap n, which engages in notches r, o in the tubes b, c (see
detail views Figs. 3, 4 and 5). Each of the tubes b and c is provided with holes
at its upper end into which the springs s snap, when the umbrella stick is drawn
out for use (see detail views Figs. 6 and 7).
When the umbrella is to be used, the sleeve e is pushed upwards until the
snap engages in the groover of the tube b, the springs s holding the three
tubes firmly together in their extended form.
When, on the contrary, the umbrella is to be folded up for the pocket, it is
held vertically with the handle upwards, and the sleeve e is pushed into the posi-
tion shown in Fig. 2. This operation will cause the ribs h to automatically turn
back at the point A, where they are hinged, the ribs g, h thus lying against
each other, as Fig. 2 shows. Simultaneously the three tubes a, b, c must be
caused to telescope into each other, the springs being pressed down with the
fingers for this purpose.
In order to prevent the ribs h folding over upon the ribs g at the hinges A,
when the umbrella is carried closed in the ordinary manner in the hand, the
following arrangement is adopted. Near the point Ï) where the inner rib f is
attached to the rib g (the other end being attached at k to the sleeve e), a
shoe pis pivoted (see detail views Figs. 8 and 9). This shoe is composed of
two side plates pp and a bridge-piece pl, which lies upon the outside of the
ribs g and h. When now, in closing the umbrella the ribs gh in extended
condition approach the tubes a, b, c, the bridge-piece pl of the shoe p slides
along the rib g. over the hinge A onto the rib h, which it accordingly supports,
preventing it from falling back upon the rib g. is a small spiral spring,
elastic band or the like, which causes the bridge piece pl always to bear firmly
against the ribs gh, one of its ends being attached to the rib f and the other
to the shoe p.

page_text: When
m (Figs. 4 and 5) is a conical filling-piece, sliding upon the tube a.
the umbrella is spanned for use, the cone m slides into the space between the
tube a and sleeve e, preventing the latter from shaking laterally to and fro.
w (Fig. 2) is the point of the umbrella, which when the latter is in the collapsed
condition, may be unscrewed at z. The handle may likewise be unscrewed from
the tube c, in order to still further diminish the length of the umbrella.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. A collapsible umbrella having a stick consisting of three or more telescopic
tubes (a, b, c) provided with holes and springs (s) and grooves (, ), substantially
as described.
2. A collapsible umbrella of the kind claimed in Claim 1, the outer ribs of
which consist of two parts (g and 4) connected together by a double hinge (A),
which permits of the lower ribs (h) turning outwardly over upon the upper
ones (g), substantially as described.
3. In a collapsible umbrella as claimed in Claims 1 and 2, the arrangement
of shoes (2) drawn towards the inner ribs (f) by springs, elastic bands or like
means (g), the bridge-piece(p') of said shoes upon closing the umbrella, sliding
over the outside of the upper ribs (g) onto the lower ribs (h), thus preventing
the latter from falling back, all substantially as described.
4. In a collapsible umbrella as claimed in Claims 1 to 3, the arrangement of
a sliding filling-piece (m), which when the umbrella is spanned for use fits into
the upper part of the sleeve (e) and prevents it from moving laterally to and fro,
substantially as described.
5. A collapsible umbrella as claimed in Claims 1 to 4, the handle and point
of which can be screwed off, substantially as described.
6. A collapsible umbrella as claimed in Claims 1 to 5, which when the sleeve (e)
is pushed to the top of the umbrella stick (a) admits of being folded together,
substantially as described.
Dated this Fourteenth day of December 1898.
