COMPLETE SPECIFICATION.
An Improved Umbrella.
We, ANNA ADAM and MAX HARTUNG Merchant both of 76 Bülow Strasse,
Berlin, Germany, 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 :—
The object of this invention is an umbrella frame designed with a view to
producing a light umbrella of pretty and elegant shape, the principal characteristic
feature of this umbrella being the umbrella-stick, which consists of a thin
aluminium tube or tubular casing into which a cane or other stick has been
inserted and firmly joined in all round by means of some suitable cementing
medium. This composite nature renders it possible to produce, with slight
dimensions, a light yet durable umbrella-stick, which, hence, combines two
exceptional advantages.
Another point chiefly studied in the manufacture of umbrellas is to construct the
umbrella frame in such a manner as to present, when folded up, the most elegant
and prettiest possible shape. In the arrangement forming the subject of this
invention, such a form is ensured by reducing the diameter of the umbrella-stick S.
(Fig. 2 & 3) from the point A (Fig. 3) where the umbrella terminates in its
external point. To this end a tube R (Fig. 2 & 3) thinner than the umbrella-
stick itself, and made of aluminium or other metal, is joined on to the extremity of
the stick so as to form the external point of the umbrella, the two being joined at
the very place where the crown or rib-socket K (Fig. 2 & 3) of the umbrella is
fastened to the stick. This place is most suitably selected as, at this point, the
umbrella cap H renders the transition from the umbrella stick S. to the thinner
external point, imperceptible to outside inspection. Between the crown K into
which the umbrella ribs C are hinged, and the termination of the actual umbrella-
stick, there is left a certain amount of hollow space, thus permitting the ribs C to
fold up closely against the stick S, whereby the elegant appearance of the umbrella
is essentially promoted. The central rib-stays or stretchers T (Fig. 1 & 2) are
U-shaped in section, so that the ribs C may be received into the grooves of the
stretchers when the umbrella is folded up. The ribs C are grooved or incised up
to their ends, and hollowed out in the neighbourhood of the slide-crown L (Fig. 2)
so that they may fold up closely at that point also, thus in no way detracting from
the compact and slender form of the umbrella.
By such an arrangement of the umbrella frame, being chiefly characterised by an
umbrella stick consisting of an aluminium tube, with a cane or similar stick tightly
inserted into and joined to it, an elegant and pretty appearance and an agreeable
lightness of the umbrella may be secured.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
:-
An umbrella frame, devised with a view to producing a light umbrella of a
pretty and elegant shape being chiefly characterised by an umbrella stick con-
sisting of a thin aluminium tube or tubular casing into which a cane or other
stick is tightly inserted and cemented by means of some suitable binding medium,
and further, by an umbrella cap which forms the transition from the actual.
umbrella stick to the thinner external point as well as by the rib-socket or
hinge-ring with hollows which permit the ribs to fold up closely against the

page_text: umbrella stick, and finally, by the ribs which are grooved or incised up to their
ends and which fit into U-shaped stretchers.
