MENTS IN KEY RINGS
Year: 1884

page_text: I JULIUS HORWITZ of 195 Cornwall Road Notting Hill in the County of
Middlesex, Mechanic, do hereby declare the nature of said invention for "IMPROVE
MENTS IN KEY RINGS" to be as follows:-
The object of this invention is to supersede the present split key rings and to
furnish a key ring which shall offer greater facilities for putting the keys on and
taking them off without at the same time incurring any risk of the keys coming
off accidentally. The improved key ring consists essentially of three parts which
are united by a fulcrum pin or rivet, viz the ring proper and two washers combined
therewith. The ring proper consists of a ring or loop-formed part which at one
side or end is provided with a head having a curved slot or a slot of contrary
flexure whereby the keys are entered. The washers are placed on each side of
the head of the ring and each is formed with a shallow notch or slot from the
circumference towards the middle, and these washers can turn independently of
each other on the head of the ring. When the two washers are brought into such
a position that their slots coincide with the entry end of the slot in the ring proper
the bow of a key can be pressed into the said entry end, and by pressing the bow
in the direction of the interior of the key ring the bow will follow the curved slot
and be entered into the ring, the two-washers being at the same time forced round
a portion of a turn till the outer ends of their notches come fair with the inner
end of the slot in the key ring. By then turning one or both washers a little to
one side the key is prevented from coming out, in fact no key can enter or leave
the ring unless both the washer notches are fair with each other and with
respectively the outer or inner end of the slot in the ring. I may if desired use
only one washer, but I prefer two as described, as it gives additional security.
The parts may be stamped out of sheet steel or other metal.
Dated this First day of March 1884.

page_text: I, JULIUS HORWITZ of 195 Cornwall Road Notting Hill in the County of
Middlesex, Mechanic, do hereby declare the nature of said invention for " IMPROVE-
MENTS IN KEY RINGS" 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 to supersede the present split key rings and to
furnish a key ring which shall offer greater facilities for putting the keys on and
taking them off without at the same time incurring any risk of the keys coming
off accidentally. The improved key ring consists essentially of three parts which
are united by a fulcrum pin or rivet; viz. the ring proper and two washers combined
therewith.
The ring proper consists of a ring or loop-formed part which at one side or end
is provided with a head having a curved slot or a slot of contrary flexure whereby.
the keys are entered. The washers are placed on each side of the head of the ring.
and each is formed with a shallow notch or slot from the circumference towards
the middle, and these washers can turn independently of each other on the head
of the ring. When the two washers are brought into such a position that their
slots coincide with the entry end of the slot in the ring proper the bow of a key
can be pressed into the said entry end, and by pressing the bow in the direction of
the interior of the key ring the bow will follow the curved slot and be entered into
the ring, the two washers being at the same time forced round a portion of a turn
till the outer ends of their notches come fair with the inner end of the slot in the
key ring. By then turning one or both washers a little to one side the key is
prevented from coming out, in fact no key can enter or leave the ring unless both
the washer notches are fair with each other and with respectively the outer or
inner end of the slot in the ring, I may if desired use only one washer but I prefer
two as described as it gives additional security.
The parts may be stamped out of sheet steel or other metal. And in order
that this invention may be more fully understood I will describe the same with
reference to the accompanying drawings, in which I have shown a form of key
ring constructed according to my invention, Figure 1 being a front view showing
the key ring in a position in. which the bow of a key may be introduced into the
ring; Figure 2 is an ordinary or closed position in which the ring cannot be
inserted or drop out; Figure 3 is a section through the key. ring; Figure 4 is a
front view with one of, the washers B removed and Figure 5 a perspective view
of the key ring with a key inserted. The ring proper A has a ring or loop-formed
part of any suitable form, circular, oval or otherwise but here shown circular, it
is formed with a head which is provided with a slot S which is curved, and in the
case shown is a curve with contrary flexure which is preferred; the key bows are
entered by this slot. B. Bare washers which are riveted on to the head of the.
ring A but so that they will turn tolerably easily. Each washer is formed with a
slot C which corresponds in width with that of the slot S in the ring A. When
both the washers are brought fair with each other and their slots fair with the
slot S as shown at Figure 1 the bow of the key can be inserted therein and by
pressing it towards the interior of the ring A it will follow the curved slot S and
the key will be entered in the ring A the two washers B being at the same time
forced round a part of a turn in fact till their slots C come fair with the inner end
of the slot S. By then turning one or both the washers B a little to one side such
for instance as shown at Figure 2 the key bow is prevented from coming out of the
key ring, I may use only one washer B but prefer two.

page_text: Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed I declare that what
I claim is:
A key ring in which the ring proper is provided with a curved slot and with
one or two rotatable washers having slots which when turned fair with the entry
or exit side of the curved slot admits respectively of insertion of a key into or
removal of a key from the key ring substantially as set forth.
