PROVISIONAL SPECIFICATION.
Improvements in Umbrella and Walking Stick Handles and the
Sticks thereof.
I, THOMAS CLARK, of 107 High Bauk, Gorton, in the County of Lancaster,
Engineer, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to connect umbrella and like handles to the
umbrella sticks in a manner which permits of the said handles being readily
attached to the said sticks in a perfectly firm and secure way while permitting of
immediate detachment when desired.
In carrying my invention into effect I arrange on the umbrella stick a tubular
socket into which I slip the handle, and I cause the two to firmly connect to each
other by a bayonet joint device, that is, an inclined slot or slots in the socket so
arranged that a pin or pins in the inserted part of the handle engage with the said
slot or slots and on twisting round the handle, firmly hold the handle in the socket
and against a shoulder.
To prevent the inserted part from turning back I arrange a spring catch which
presses into a slot and holds the handle and socket so that no turning round can
occur till the spring is depressed.
Instead of the bayonet joint arrangement for connecting together the handle and
stick I may use other devices such as a short screw joint with spring catch or
detent to prevent turning. To allow rapid insertion, the screw may be of the type
known as "interrupted"; such a screw as is used for holding the breech blocks of
guns. In this type of screw, parts of the screw are longitudinally cut away both
in the male and female ends, and the male end is then inserted, the screw part
passing into the grooves or cut away parts. When inserted it is turned round and
firmly holds the whole length of the screw. A spring catch may be used to prevent
turning back.
In my improved umbrella handles and sticks I prefer to use light metallic tubes
for the stick part, as suchi metallic tubes have many advantages over sticks, and
provide the socket for my detachable handle without special manufacture of such
socket.
My invention has many advantages among which may be mentioned the power
of changing the handle of an umbrella or stick and also the ease of packing by
taking off the handle and so shortening the umbrella or stick to a moderate and
convenient compass.
The latter advantage is specially applicable to cyclists
umbrellas or sticks.
COMPLETE SPECIFICATION.
Improvements in Umbrella and Walking Stick Handles and the
Sticks thereof.
I, THOMAS CLARK, of 107 High Bank, Gorton; in the County of Lancaster,
Engineer, 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 my invention is to .connect' umbrella and like handles to the
umbrella sticks in a manner which permits of the said handles being readily

page_text: attached to the said sticks in a perfectly firm and secure way while permitting of
immediate detachment when desired.
In the accompanying sheet of explanatory drawings-
Figure 1 is a sectional elevation of a portion of a stick with one form of my
improved detachable end shown removed.
Figure 2 is a sectional elevation of another form of my detachable end, Figure 3 is
an elevation of the same, and
Figure 34 is a sectional plan showing my improved spring clip or lock in
detail.
Figure 4 is a sectional elevation of another form of independent end or handle
attachment which I also adopt.
In carrying my invention into effect in the manner shown in Figures 2, 3 and 34,
I arrange on the umbrella stick C a tubular socket B₁ into which I slip the
handle HA, and I cause the two to firmly connect to each other by a bayonet
joint device; that is, an inclined slot or slots Ef in the socket B', so arranged that
a piu D or pins in the inserted part of the handle socket A engage with the said
slot or slots Ef and on twisting round the handle, firmly hold the handle in the
socket and against a shoulder. To prevent the inserted part A from turning back
I arrange a spring catch F G which presses into a slot and holds the handle H
and socket B so that no turning round can occur till the spring G is depressed.
Instead of the bayonet joint arrangement for connecting together the handle and
stick I may use other devices such as a short screw joint A B shown in Figure 1,
with spring catch or detent to prevent turning when desired. To allow rapid
insertion, the screw may be of the type known as "interrupted" such a screw as is
used for holding the breech blocks of guns. In this type of screw, parts of the
screw are longitudinally cut away both in the male and female ends, and the male
end is then inserted, the screw part passing into the grooves or cut away parts.
When inserted it is turned round and firmly holds the whole length of the screw.
A spring catch may be used to prevent turning back.
I sometimes unite the two portions together such as H C¹ shown in Figure 4 by
means of a flanged socket L L' which I screw into the handle end H H and also
into the stick end C¹ respectively employing a junction screw piece KM which
draws both portions tightly together against the flanged ends L L¹.
In my improved umbrella handles and sticks I may use light metallic tubes for
the stick part as such metallic tubes have many advantages over sticks and
provide the socket for my detachable handle without special manufacture of such
socket.
As applied to umbrellas I sometimes make the joint immediately above the ends
of the frame wires at the position the said wires occupy when the umbrella is
closed and by this I am enabled to shorten the umbrella as much as possible.
My invention has many advantages among which may be mentioned the power
of changing the handle of an umbrella or stick and also the ease of packing by
taking off the handle and so shortening the umbrella or stick to a moderate and
convenient compass. The latter advantage is specially applicable to cyclists
umbrellas or sticks.
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. The construction of umbrella and parasol sticks having the upper portions
detachable, substantially as and for the purposes hereinbefore described and as
illustrated in the accompanying drawings.
2. The construction of handles for walking sticks, in which the upper portion of
the said walking stick is made detachable in the manner herein before described and
as illustrated in the accompanying drawings.
3. The construction of umbrella, parasol and sticks having the upper portion
detachable, the connecting device comprising in combination a bayonet joint with

page_text: spring catch or a screw with spring catch, substantially as and for the purposes
hereinbefore described.
4. Shortening an umbrella, parasol, or walking stick for convenience in packing
or carriage by constructing the said umbrella, parasol, or walking stick in two
5 portions securely connected together while easily separable, substantially as
herein before described and as illustrated in the accompanying drawings.
Dated this 17th day of November 1893.
