Improvements in Umbrellas and the like.
I MAX GOTTING of Erfurt in the Empire of 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:-
This invention relates to umbrellas, parasols, sunshades and the like and consists
in constructing the top notch in such manner that the covering and its supports may
be readily and rapidly removed from the stick and be replaced by another so that
the stick may be provided with a covering suitable to the taste and answering the
present purpose of the owner, or the covering may be entirely removed and the
stick merely used as a walking stick.
In the accompanying drawings,
Figs. 1 to 8 illustrate three modes of carrying my invention into practice.
In the arrangement of top notch shown in Figs. 1 to 4, a sleeve a having four
ribs and screw threaded at its upper part bears against the shoulder of the stick
and is fixed in any suitable manner to the stick. The notched ring d provided with
four grooves corresponding with the four ribs of the sleeve a is forced onto the
sleeve and is secured by the nut e working on the upper end of the sleeve a.
Figs. 5 and 6 show another mode of carrying this invention into practice. In
this modification the sleeve a is dispensed with and the notched ring d is provided
with a screw threaded boss from which extend upwardly spring claws f. The nut h
is provided with a conical opening at its upper end and works on the screwed boss
of the notched ring d, and on screwing down the nut the bent up and toothed
edges g of the spring claws fare firmly pressed into the stick as shown in Fig.
and fixes the notched ring d in position.
c
In the modification shown in Figs. 7 and 8, the sleeve a and notched ring d are
forced over four spring catches k fixed to the stick. The free ends of these spring
catches k. are bent over to form hooks and when the sleeve a and ring d are forced
up enter openings o formed in the stick so as to allow them to pass and out of
which they protrude immediately the notched ring d is placed in position upon the
sleeve a. so as to prevent them from being withdrawn. The sheet metal sheath / is
forced over the springs and fixed in any suitable manner.
It will be readily seen in all these arrangements that by unscrewing the nut e
or h or taking off the sheath 1, the top notch together with the ribs, stretchers,
runner and cover of the umbrella can be removed.
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:
1. A top notch for an umbrella consisting of a fixed sleeve a provided with ribs b
on its outer periphery and with a screw thread, and of a notched ring d provided
with grooves to receive the ribs b, and of a nut e working on the sleeve a, the whole
substantially as described.
2. A top notch for an umbrella consisting of a notched ring d provided with an
upwardly extending screw threaded boss and spring claws and of a nut working
on the boss and serving to force the toothed edges of the claws f into the stick to
fix the notched ring into the stick, the whole substantially as described.
3. A top notch for an umbrella consisting of a sleeve a and notched ring d forced

page_text: over spring catches k, covered by sheath and serving to hold the notched ring d
upon the ring a and fix them both to the stick substantially as described.
Dated this 9th day of November 1891.
