PROVISIONAL SPECIFICATION.
Improvements in Umbrellas and Sunshades.
1, KURSANSKY HYMAN, of 6, Fasset Square, Dalston, London, N. Umbrella
Manufacturer; do hereby declare the nature of this invention to be as follows:-
My invention relates more particularly to umbrellas and has for its object to
render such articles less bulky in appearance than they are as usually constructed,
without any sacrifice of the strength of the stick such as has generally resulted
from other improvements having the same end in view. A further object of my
invention is to render the umbrella lighter and at the same time more durable.
According to my invention the "top notch" (in which lies the wire forming the
hinge pin for the upper ends of the ribs) is formed at the upper end of a metal
socket piece which I term the "hub," interposed between the handle portion of the
stick (which is screwed or otherwise secured in the open lower end of the socket
piece) and the ferrule end of the same. The hub (which may be of any convenient
length towards the handle end of the stick, whose length may in consequence be
proportionately reduced) is preferably slightly conical the smaller diameter being
towards the upper end.
The depth of the top notch is equal to that of the ribs, which lie when closed in a
series of longitudinal grooves or flutings formed in the surface of the hub, the
grooves extending from the top notch, to which they are equal in depth, any desired
distance downwards towards the handle, and gradually becoming shallower until
they finally merge in the outer surface of the hub.
Above the top notch the hub is prolouged to form a male screw taking into a
female screw formed in the lower end of a second tubular socket or union piece,
into the upper end of which is inserted and secured the ferrule portion of the stick.
The upper rosette is secured over the top of the ribs and covering by the union
piece being screwed down upon it and abutting against the hub.
It is obvious that the hub may be reduced in diameter to any extent consistent
with provision being left for the requisite number of grooves, and consequently
both the bulk and weight of the umbrella may be diminished in proportion.
The ribs when closed are prevented from being twisted round the stick in the
process of "rolling up "the umbrella by their being held in the grooves of the
hub, and the strain upon the wire in the top notch being thus considerably reduced,
the wire itself will be more durable.

Improvements in Umbrellas and Sunshades.
I, KURSANSKY HYMAN, of 6, Fasset Square, Dalston, London, N., Umbrella
Manufacturer, 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 :-
My invention has for its object to enable the umbrella or sunshade to be rolled

page_text: in a smaller compass so as to present a slim and elegant appearance, without
sacrificing the strength of the stick.
The invention will be described with reference to the accompanying drawings,
forming part of this Specification, wherein Figure 1 represents a part elevation of
as much of the stick and frame of an umbrella as is necessary for the explanation
of my invention, Figure 2 being a cross-section, on line 2-2. Both figures are
drawn double full size.
The
According to my invention, the top notch A is made in one with a metal rod B
(which I term the "hub") which is made tubular at the lower part to form a
socket for connection to the stick C which is secured therein by cross pins or by
screw-threading the socket internally and screwing the stick into it. The hub B
is continued above the top notch A in the form of a male screw d on which screws
a corresponding screw-threaded socket or cap-piece D, the lower end of which is
made flaring to replace the ordinary open cap and the upper end of which is made
tubular to receive the point or ferrule piece E of the stick. The hub B thus
interposed between the handle portion C and the point or ferrule portion E of the
stick is longitudinally grooved or fluted from the top notch A downwards for a
distance of about two to three inches or about as far as the socket portion b, the
grooves being equal in depth at their upper end to, or slightly less than, the depth
of the slits a of the top notch in which the ribs ; are hinged, as usual, the grooves
becoming gradually shallower towards the lower end until the bottoms of the
grooves finally run out flush or merge with the surface of the hub B.
projecting ridges 9 which separate the grooves f practically correspond at their
upper ends to the full diameter of the top notch and project beyond the diameter
of the lower part 6 of the hub in order to afford sufficient lateral support for the
ribs when received in-the grooves g to prevent torsional strain being transmitted by
the ribs in the act of rolling up the umbrella to the wire h upon which the ribs are
hinged in the usual way, the diameter, measured at the top of the ridges g, being
slightly greater towards the handle end than towards the notch end. The whole
of the hub B, including the upper portion out of which the notch is formed and the
end d, is a metal rod of brass or aluminium cast with the grooves f in it and then.
machine finished to render the grooves smooth. The slits a and the circumferential
groove for the hinge pin wire are cut out by milling tools, the slits a being made of
only sufficient. width to receive the flattened perforated ends of the ribs, whilst the
grooves are wide enough to admit the full width of the ribs which, when the
umbrella is folded lie wholly or nearly so within the grooves at the upper part and
close against the surface of the hub at the lower part, so as to cause the umbrella
to present a slim or tapering appearance.
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 :-
The herein described improvement in umbrellas and sunshades, which consists in
constructing the top notch in one with a longitudinally grooved or fluted metal rod
having grooves for receiving the ribs of tapering depth separated by ridges, the
lower part of the rod being adapted to be connected to the handle portion of the
stick and the upper part having a male screw formed on it for connection with a
cap-piece carrying the point or ferrule portion of the stick, substantially as
specified.
