I, GEORGE FREDERICK HALL, of 97, Pritchett Street, in the City of Birmingham,
Manufacturer, do hereby declare the nature of this invention to be as follows; -
This invention relates to the joints of curtain rings and to analogous pole rings
for various uses, and has for its object to provide a lock fast and lap joint.
The improvements consist in forming at one end of the strip or section of metal
or the like from which the ring is made, a tongue or extension which is caused
to socket within the other and hollow end, and in the engaging parts are locked
together by indentation, or by pinning or otherwise.
In carrying out my invention in connection with a curtain ring made from bent
metal of any cross section, I take a length of such metal, and I spin or otherwise
fashion the same into a hollow ring, and then by dies and pressure I flatten one
end and, if necessary, trim the same down into the form of a tongue or shouldered
extension of a size suitable for engaging socket-wise into the other end. When
in such position, the tongue is there affixed or locked by a teat indentation which
impresses the metal of the one into the metal of the other, so that the tongue is
prevented from being withdrawn out of the socket. The eye for the curtain or
like pin is then secured to the ring, either by pin-rivetting or otherwise. Or in-
stead of indenting the metal to form the connection, the shank or pin extension
of the eye is passed through coincident holes in the socketting parts and its end
is rivetted up on the inside of the ring.
Instead of a tongue being formed, the break joint may be effected by inserting
a separate tongue or tie piece within the two socketted ends and there securing
the same by two indentations or by a pair of cross rivets or pins.
As another modification, the tio piece may be made from a length of wire, with
its ends flattened for insertion, whilst its middle part is formed into the pin loop
or eye, and the socket ends of the ring have semi-circular clearances for the shank
of the said eye, so that they shall make a perfect butt at the seam.
The rings may be made from continuous helical lengths, which is cut up into
the required ring sections, whilst still on the mandril, by a cross-cutting saw or
other suitable tool.
The said rings may also be made from metal of what is known as a Belcher
section, i.e. a section comprehending nearly a complete circle or oval, one end of

edges of the other end.

Improvements in or in the Manufacture of Curtain and Pole Rings
for various uses.
I, GEORGE FREDERICK HALL, of 97, Pritchett Street, in the City of Birmingham,
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:-
This invention relates to the joints of curtain rings and to analogous pole rings
for various uses, and has for its object, to provide a lock fast and lap joint, and.
also an efficient means for temporily connecting together the meeting ends of a
ring to enable the same to be either efficiently polished or burnished.
The improvements consist in forming at one end of the strip or section of metal
or the like from which the ring is made, a tongue or extension which is caused
to socket within the other and hollow end, and-the engaging parts are first
locked together (prior to either polishing or burnishing the ring) by indentation,
and afterwards the lock connection is made permanent by passing the shank of
the curtain-pin eye through holes in the engaged parts and securing it by clinch-
ing, although cross-pinning or the like may be employed for the purpose.
In carrying out my invention in connection with a curtain ring made from bent
metal of any cross section, I take such a length of hollow metal as is represented
in Figure 1, and I spin or otherwise fashion the same into a hollow ring a, as
represented in elevation and edge view in Figures 2 and 3, with the opposite open
ends a¹, a², coming together, and then by dies and pressure I flatten the one end
a', as represented in elevation in Figure 4 and edge view in Figure 5. The
flattened end is next trimmed down into the form of a tongue or shouldered
extension a³ as represented in the elevation Figure 6 and edge view Figure 7, of
a size suitable for engaging socket-wise into the other and open end a³, which is
shown in section in the said Figure 7. When in such position, the said open
end a², is closed down upon the tongue engaging it, as represented in Figure 8,
after which the said socketting parts are affixed or locked together by a teat in-
dentation a¹ (see Figures 9, 10 and 11) which is made by a punch or other tool
adapted to impress the metal of the one into the metal of the other, so that the
tongue part a³ is prevented from being withdrawn out of the flattened socket a³.
This method of locking the socketting ends together by means of collectively
indenting the metal (which is represented in plan in Figure 9, longitudinal sec-
tion in Figure 10 and in similar section upon an enlarged scale in Figure 11)
provides an easily made and efficient connection for the ends of the ring length
during either the polishing or burnishing of the same, which is the next stage in
the manufacture.
After the ring is either polished or burnished, a hole a6, is made through the
flattened socketting parts, preferably through the indentation, to receive the

page_text: shank 61, of the eye b, with which the curtain pin or the like is connected Figure
12 represents a section of the connected ends with the hole a, made therethrough,
and Figure 13 is a similar section but upon an enlarged scale, whilst Figure 14
represents an elevation and an edge view of the curtain-pin eye, separately. The
shank of the said eye is split, so that after being introduced from the outside of
the ring through the hole as, the split parts are opened out and clinched down upon
the inner side of the engaged and flattened parts, which, in addition to forming
the connection of the eye to the ring, also permanently secures together the ends
of the said ring by preventing the withdrawal of the tongue end from the corres-
ponding socket part.
The connection of the eye to the ring is represented in section in Figure 15, and
in edge view (with the eye in elevation) in Figure 16, whilst Figure 17 shows an
underside plan of the lock-joint part of the ring, with the eye in edge view.
Figure 18 is a similar section as Figure 15 but upon an enlarged scale, whilst
Figure 19 represents, upon the same scale as Figure 18, a plan of the inner side of
the said joint part, showing the clinching of the shank of the eye.
Instead of securing the eye to the ring in the way described, its attachment may
be effected and the locking of the engaged ends of the ring provided for, by
means of a cross pin or rivet passing through coinciding holes in the eye and in
the tongue and socket of the ring, or the shank of the eye may be rivetted instead
of being split and clinched.
Instead of forming a tongue at one end of the ring, the break joint may be
effected by inserting a separate tongue or tie piece within the two flattened socket
ends and there securing the same by two indentations or by a pair of cross rivets
or pins.
As another modification, the tie piece may be made from a length of wire, with
its ends flattened for insertion, whilst its middle part is formed into the pin, loop
or eye, and the socket ends of the ring have semi-circular clearances for the shank
of the said eye, so that they shall make a perfect butt at the seam.
The rings may be made from continuous helical lengths, which is cut up into
the required ring sections, whilst still on the mandril, by a cross-cutting saw or
other suitable tool.
The said rings may also be made from metal of what is known as Belcher
section, i.e., a section comprehending nearly a complete circle or oval, one end of
each length being flattened into a tongue which takes under the overlapping
edges of the other end.
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;
First In the manufacture of curtain and other rings, forming at one end of
the strip or section from which the ring is made, a tongue or shouldered exten-
sion, adapted to take or socket within the other end, which is then flattened down
and the engaging parts locked together, substantially as and for the purpose
described and set forth.
Secondly: In the manufacture of curtain and other rings, forming at one end
of the strip or section from which the ring is made, a tongue or shouldered ex-
tension, adapted to take or socket within the other end, which is then flattened
down and the engaging parts locked together by indentation, substantially as
and for the purpose described and set forth.
Thirdly: In the manufacture of curtain and other rings, forming at one end
of the strip or section from which the ring is made, a tongue or shouldered ex-
tension, adapted to take or socket within the other end, which is then flattened
down and the engaging parts locked together by piercing the same to receive the.
shank or connection pin of the attached eye, substantially as and for the purpose`
described and set forth.

as herein described and set forth.
Fifthly: The modificated form of connection between the two ends of a curtain
ring length, in which a separate tongue piece is inserted into two flattened socket
