心
I, GUILLERMO PABLO UHLENBROICH of 39 Finsbury Square E.C. in the
County of London, Merchant, do hereby declare the nature of this invention to be
as follows:-
My invention relates to a new or improved key-ring and consists of a flexible
ring of steel or other metal split or open in one place. The two ends of the ring
are bent at right angles and have a shape resembling that of a fish hook being pro-
vided at their base with a barb or projection and rounded off at their apices. By
squeezing the ring the two ends can be inserted in the opening formed in a hollow
ball or in a small knob or head of prismatic or other shape, so that when the ring
is subsequently released the two ends thereof bear firmly against the edges of the
said openings which edges fit under the barbs aforesaid.
Dated the 23rd day of November 1892.

COMPLETE SPECIFICATION.
A New or Improved Key-ring.
I GUILLERMO PABLO UHLENBROICH of 39 Finsbury Square London E.C.
Merchant 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 relates to a new or improved key-ring and has for its object to
remedy the defects attending the key-rings ordinarily used, whereby the keys are
more readily attached and detached from the rings than heretofore.
To remove a key from such a ring it was necessary to open the end of one half
of the same with the nail which was liable to be broken independant of the pain
resulting frequently from the efforts thus exerted, while, if several keys were required
to be removed at the same time this operation had to be successively repeated causing
considerable inconvenience and loss of time.
The key-ring provided according to my invention euables several keys to be
simultaneously attached thereto and detached therefrom..
This improved ring consists of an annular steel or other wire split at one point
of its periphery where its two ends are bent at right angles and provided at their
apices with barbs which, when these ends are pressed together and inserted within
a hollow ball, marble or knob securely close the ring and prevent the same from
being accidently opened.
In the accompanying drawings
Fig. 1 is a side elevation of my improved key-ring with keys attached thereto.
Fig. 2 is a corresponding view with the ball or knob detached and the keys
removed.
Fig. 3 is a central longitudinal section of the upper part of the device drawn at
an enlarged scale.
My improved key-ring consists of a flexible metal ring R split as shown and the
ends e of which are bent at right angles and are provided at their extremities with
barbs b. B is a hollow ball or marble furnished with a circular opening o wherein
enter the barbed apices of the ends e. When it is required to attach or detach a
key, the ends e are pressed together between the thumb and index finger until they
can be withdrawn from the ball or knob B, when the keys are slipped on or off as
[Price 8d.1

page_text: required; the ends being again compressed until they can re-enter the opening in
the ball and occupy therein the position clearly shown in Fig. 3 of the drawings,
the under sides of the barbs 6 bearing against the peripherial edges of the metal
around the hole or opening.
Like letters of reference indicate corresponding parts throughout the figures.
Fig. 4 shows an alternative. The ends of the split ring R are in this case bent
inwards instead of outwards, but in all other respects this arrangement is similar to
the former.
Fig. 5 shows another modification in which the ball B is replaced by a hollow
piece p hinged at n to one of the ends e which has accordingly no barb.
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 :
The improved key-ring arranged substantially as herein described and shown and
for the purpose set forth.
Dated this 13th day of February 1893.
