PROVISIONAL SPECIFICATION.
Pocket Umbrella.
I, HUGO HAEGERMANN of 50 Hamburger Strasse, Dortmund, Wine Merchant,
do hereby declare the nature of this invention to be as follows:-
The present invention relates to an umbrella which can be easily folded together
into such a size as to be conveniently carried in the pocket, and which when
opened, preserves-notwithstanding the joints employed-a neat appearance
because of the surface of the covering being smooth all over.
In the accompanying drawing
Fig. 1 shows this pocket-umbrella as it looks when folded together.
Fig. 2 is a partial longitudinal section of the umbrella-frame folded together.
Fig. 3 is the umbrella-frame as opened out.
Figs. 4 & 5 are single views of the joint-connection of the umbrella-rods when
opened and when folded together.
'
The umbrella-stick consists of three telescopically adjustable tubes abc of which
the tubes ab carry the plates ik serving for fixing the umbrella-rods D and the
supports f
The rods D are composed of the inner parts g and the outer parts h. The inter-
mediate joint A connects both parts by means of the hinges rs, and enables the
halves of the rods to be completely folded together when the umbrella is closed
(Fig. 5). Between the tubes b and c (Fig. 2) is the slide e which is pushed over
tube b. The screw d connects the slide e with the interior tube a and slides in
guide n of tube b.
If the umbrella is required to be opened, the bands tt are opened, and tube c'is
drawn back so far that part c, touches part of the closure C, and that thus the
pin p (Fig. 3) gets into the axial groove g. If tube c is then turned round (to the
right) the pin p is moved into the rectangular branching of the groove g and thus
the tubes bc are connected into a single umbrella-stick.
After this the halves of the rods are stretched out (Figs. 3, 4), and by
adjusting the slide e and the tube a connected with the same, the umbrella is
opened.
As soon as, in doing this, the pin d of the closure-ring B which is driven by
means of this pin projecting into the slit o of tube a, has arrived at the end of the
axial slit n, the closure-ring is turned so that the pin d is pushed into the lateral
slit n', thus preventing the umbrella from collapsing. The tightness of the cover
at the same time tightly supports the chamfers I m of the intermediate joint A
against the respective shapings in the hinges, so that these chamfers offer to the
rods a sufficient support and prevent an excess of the stretched position of the rod
halves.
Through the arrangement of the intermediate joint A, which is as broad as the
ends of the rods, it is possible to connect the parts gand h in such a way that, when
the umbrella is opened to the side of the material, there are no prominent parts or
inequalities, so that the surface of the cover is entirely smooth.
In closing the umbrella, the great suppleness of this combination prevents the
mechanism from sticking fast and thus causing the rods to get bent.
Dated this 25th day of July 1893.

I, HUGO HAEGERMANN, Manufacturer, of Hamburgerstrasse 50 Dortmund, in
the German Empire, 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 relates to a portable umbrella which, while it is capable of being,
folded up in compact shape, and reduced in size, so that it can readily be placed in
a' coat or other pocket, retains, when opened, the usual appearance of a non-folding
unbrella, inasmuch as all parts of the material wherewith it is covered present,
when stretched, a smooth and even surface, entirely concealing the joints.
The invention will be best understood by reference to the accompanying
drawings, in which:
Fig. 1 is an outside view of the improved folding umbrella, in the compact or
folded condition :
Fig. 2 is a sectional elevation of the folded umbrella frame or carcase;
Fig. 3 is a similar elevation of the open frame, and
Figs. 4 and 5 are detail views illustrating the jointed connection of the ribs,
which are shown both folded and extended.
The umbrella stick consists of three telescoping tubes abc. The tubes a and b
carry, respectively, the notch i, to which are pivoted the ribs and the runner k, to
which the stretchers are moveably attached.
The ribs consist each of an inner portion g, secured to the notch, and of an outer
' portion ; the two portions being joined by means of a double hinge plate A. and
hinge-pins r, s. The hinge is so constructed as to enable the two halves of the rib
to be folded completely, or brought into close proximity to each other, as shown in
Fig. 5; while at the same time-it prevents-them; when opened; from being folded
backwards, beyond the point at which they form a continuous rib, as indicated in
Fig. 4; for which purpose projections or stops and m, provided on the said hinge
plate, are adapted to meet, or abut against, inclined faces in the heads of the
ribs and h, when the umbrella rib is unfolded or stretched out. When the
umbrella is open, the tension of the covering material causes the faces of the said
projections to be firmly pressed against the said ribs g, h, as illustrated in Fig. 3,
itbereby imparting the requisite rigidity to the skeleton or frame. As no part of
the hinge has a larger sectional area than the ends of the linked rib sections h
and g, the covering material does not assume a crumpled appearance through any
part of it being raised by projections, but is perfectly smooth throughout. And
when the umbrella is folded up, the readiness with which these linked parts turn
upon the hinges, precludes any jamming action, apt to result in the bending or
warping of the ribs; nor is the material liable to be nipped or caught between the
meeting edges of the hinge, since the said edges are free from sharp angles and
notches or indentations.
The innermost tube a, which carries at its upper end the notch i for the upper or
, inner rib-sections to be attached to, is provided with a pin or stud d, adapted to
slide in a longitudinal slot or guide-groove n, formed in the tube b, and to limit the
upward movement of the tube a, while the umbrella is being opened.
The means for opening and closing the umbrella, or in other words, for dis-
placing the tube a in relation to the tube, chiefly consist of a sleeve e and a
ring B passed, over the said tube ; from each of these a stud or pin (d' and d
respectively) projects inwards into the tube a, being guided in the tube b by a
slot n, and the end of pind engages in a circumferential groove o, formed in the
inner tube a. The said slot n in the tube b is extended sideways at two points, one
of which, n', is at the upper end, and the other (not shown) near the lower end of
the slot n, and the pin d is adapted to engage in either of these extensions or

page_text: notches, according as the sleeve e and ring B are in their upper or lower position.
or, in other words, according as the umbrella is opened or closed; the said tube B.
being slightly turned about its own axis, ou reaching either limit of its movement,
in order to enable the said pin d so to engage, and thereby to fix the inner tube-
or hollow stick a in the
open or "closed" position, as the case may be.
"
The outermost tube or sleeve c merely serves to extend the umbrella-stick, being-
adapted, whilst the stick is thus fully extended, to be secured to the tube b by
means of a bayonet-joint; while a stud or pin p, projecting inwardly from the
tube c, engages in the slot or groove 9 in the enlarged lower end of the tube b, when.
either of the two tubes is, to a sufficient extent, displaced longitudinally in relation.
to the other and turned about its own axis.
In practice, the improved folding umbrella is used as follows;-
C
Assuming it to be folded and tied up, as shown in Fig. 1, when required for use;
the fastening ties or bands are first unfastened, and then the knob or handle which
terminates the external tube c is pulled outwards until the stud or pin p enters the-
slot 9; when, by a slight rotary movement, the two tubes b and c are so interlocked
as to form jointly a rigid piece. The outer halves of the ribs are next turned
down into the position wherein they are fit to stretch the cloth, and the fastening
sleeve is turned on its axis sufficiently to enable the pin d to leave the notch n' and
to enter the longitudinal slot n. The said sleeve is now shifted longitudinally and
then turned so as to cause the pin d to enter the notch a¹. This completes the.
opening operation, and the umbrella is ready for use in the ordinary way.
The folding umbrella may, if desired, be fitted with means for automatic tension,
consisting of a spiral spring located within the tube and adapted to exercise.
outward pressure upon the tube a, and thereby automatically to expand the-
umbrella in which case it will be necessary to overcome the resistance of, and.
compress, the said spring, to effect the closing of the umbrella when required.
The improved umbrella may also, like ordinary umbrellas, be made use of in the
guise of a walking stick, for which purpose it need only be folded up, without the.
telescoping tubes being slid into each other; an end piece F, (Fig. 2), fitted with.
the usual ferrule, being screwed on to the threaded end of the tube a, as shown.
Having now particularly described and ascertained the nature of the said inven--
tion, and in what manner the same is to be performed, I declare that what I'
claim is :-
1. A portable folding umbrella, the folding ribs of which consist each of two.
halves 9 and, linked together by means of a double hinge A, which is so con--
structed, that when the rib is fully expanded or stretched out, the projections or
stops m prevent the rib-sections and from turning backwards upon their
hinges, further than they are required to do in order to unfold themselves to the
full extent; while the umbrella may be folded without the covering material being
caught in the hinge; such material presenting moreover, when stretched, an even,
and smooth surface.
2. In a portable folding umbrella, the stick of which consists of tubes, telescoping
or sliding within each other, the arrangement upon the external tube 6 which,
carries the runner or stretcher-carrier k, of an adjustable sleeve, so combined with
the inner tube a whereon is mounted the notch or rib-carrier i, that a pin or stud d
provided on the said sleeve, on passing through a slot n in the tube b, enters a
groove o formed in the tube a; so that by shifting the said sleeve upwards or
downwards, and then turning it, so that the pin d may enter one of the extensions n¹
(as the case may be) of the slot n, the tube a may be fixed accordingly in either-
its upper or its lower position, with the result, that the umbrella will remain either-
open or closed.
