PROVISIONAL SPECIFICATION.
An Improved Chain Link.
I, IRVING BROWN, of 658 Cedar Avenue, Cloveland, Ohio, United States of
America, Manufacturer do hereby declare the nature of this invention to be as
follows:
My invention consists of a chain link, which has the ends of the metal piece bent
backwardly and overlapping each other, and the extremities of said ends interlocking
with that portion of the metal piece that lies intermediate of such bent back portions.
Such form of chain link causing each said interlocking extremity to be clamped
between its companion interlocking extremity and said portion of the metal piece that
lies intermediate of such bent back portions; thus the better maintaining said inter-
locking extremities against disengagement, as the link is subjected to great tension.
Such form of link further causes said interlocking extremities to serve as a tie, and
also as a brace, to the link.
In the accompanying drawing
Figure 1 is a perspective view of a chain link representing my preferred form of
embodiment of the principle of iny invention.
Figure 2 is a plan view of the same.
Figure 3 is a plan view of the same, with a part of one of the bent back portions
broken away.
Figures 4 and 5 are respectively transverse sections of said link, taken on opposite
sides of the interlocking loops.
Figure 6 is a perspective view of same link, with the interlocking loops broken
away.
Figures 7, 8, 9 and 10, are perspective views of different chain links, respectively
representing modified forms of embodiment of the principle of my invention.
That portion of the metal pieco which is located intermediate of the two bent back
portions, is lettered as A; while said two bent back portions of the metal piece are
respectively lettered as A' A'. Thus A is that portion of the chain link which is
located intermediate of the respective ends at a of the link, and which extends
continuously from one link end to the other link end. Said bent back portions A' A²
overlap each other as shown at ; and the extreme ends of said bent back portions
are respectivly bent around portion A, thereby respectively forming the two inter-
locking loops 6 b³.
This formation of link causes each interlocking extremity of the metal piece to be
clamped between the companion interlocking extremity and said portion A; thereby
materially lessening the strain otherwise brought to bear on the loops, and greatly
strengthening the link against longitudinal tension. And the greater the tension to
which the link may be subjected, the stronger will such clamp be. Such formation
also ties the different portions of the link together; and further, braces the link in
resistance against lateral pressure. In the links shown in the first seven figures, a
shoulder c is formed in the portion A of the metal piece; and against opposite faces
of said shoulder, the said interlocking loops 66 are respectively bent. The links
shown in Figures 8, 9 and 10, are respectively formed without said shoulder. The
links shown in Figures 8 and 9 are respectively similar to the links shown in
Figures 1 and 7, except that they are formed without said shoulder. In Figures 1, 2,
3, and 6, the shoulder is shown located in substantially the longitudinal centre of
said portion A; while in Figure 7, said shoulder is formed at a less distance from
one link end than it is from the other. In Figures 1, 2, 3 and 8, the interlocking
loops are respectively located to opposite sides of the longitudinal centre of said
portion A. In Figures 1, 2, 3, 7, 8 and 9 each interlocking loop is farther from

page_text: the end of the link from which it was bent, than is the companion interlocking loop.
In Figure 10 each interlocking loop is nearer the end of the link from which it was
bent, than is the companion interlocking loop.
The chain link may, be made of wire, rod, or other suitable material; said, material
being of any desired form in cross section.
The foregoing description and accompanying drawings set forth in detail, certain
forms of chain links in embodiment of my invention; the same may however be
modified provided the principles of the form respectively recited are employed.

COMPLETE SPECIFICATION.
An Improved Chain Link.
I, IRVING BROWN, of 658 Cedar Avenue, Cleveland, Ohio, United States of
America 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 :-
My invention consists of a chain link, which has the ends of tho metal piece bent
backwardly and overlapping each other, and the extremities of the said ends inter-
locking with that portion of the metal piece that lies intermediate of such bent back
portions. Such form of chain link causes each of the said interlocking extremities to
be clamped between its companion interlocking extromity and the said portion of the
metal piece that lies intermediate of such bent back portions; thus better maintaining
the said interlocking extremities against disengagement, as the link is subjected to
great tension. Such form of link further causes the said interlocking extremities to
serve as a tie, and also as a brace to the link.
In the drawing left, with the provisional specification
Fig. 1 is a perspective view of a chain link representing my preferred form of
embodiment of the principle of my invention;
Fig. 2 is a plan view of the same :
Fig. 3 is a plan view of the same, with a part of one of the bent back portions
broken away;
Figs. 4 and 5 are respectively transverse sections of said link, taken on opposite
sides of the interlocking loops;
Fig. 6 is a perspective view of same link, with the interlocking loops broken
away;
Figs. 7, 8, 9 and 10, are perspective views of different chain links, respectively
representing modified forms of embodiment of the principle of my invention.
That portion of the metal piece which is located intermediate of the two bont back
portions, is lettered as A, while the said two bent back portions of the metal piece
are respectively lettered as A¹ A'. Thus A is that portion of the chain link which is
located intermediate of the respective ends a¹ a² of the link, and which extends
continuously from one link end to the other link end. The said bent back
portions A A² overlap each other as shown at ò; and the extreme ends of said bent
back portions are respectively bent around portion A thereby respectively forming, the
two interlocking loops b¹.
This formation of link causes each interlocking extremity of the metal piece to be
clamped between the companion interlocking extremity and said portion A; thereby
materially lessening the strain otherwise brought to bear on the loops, and greatly
strengthening the link against longitudinal tension. And the greater the tension to
which the link may be subjected, the stronger will such clamp be. Such formation
also ties the different portions of the link together; and further, braces the link in
resistance against lateral pressure.
In the links shown in the first seven figures, a shoulder c is formed in the portion A

page_text: of the metal piece; and against opposite faces of said shoulder, the said interlocking
loops 66 are respectively bent. The links shown in Figs. 8, 9 and 10, are
respectively formed without the said shoulder. The links shown in Figs. 8 and 9 are
respectively similar to the links shown in Figs. 1 and 7, except that they are formed
without said shoulder. In Figs. 1, 2, 3, and 6, the shoulder c is shown located in
substantially the longitudinal centre of the said portion A; while in Fig. 7, said
shoulder is formed at a less distance from one link end than it is from the other.
In Figs. 1, 2, 3 and 8, the interlocking loops are respectively located to opposite
sides of the longitudinal centre of said portion A. In Figs. 1, 2, 3, 7, 8 and 9 each
interlocking loop is farther from the end of the link from which it was bent, than
is the companion interlocking loop. In Fig. 10, each interlocking loop is nearer
the end of the link from which it was bent, than is the companion interlocking
loop.
The chain link may be made of wire, rod, or other suitable material; said material
being of any desired form in cross section.
The foregoing description and accompanying drawing sets forth in detail
certain forms of chain links in embodiment of my invention; the same may
however be modified provided the principles of the form respectively recited are
employed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I wish it understood that
I claim :-
First. A chain link having the ends of the metal piece bent back and overlapping
each other and interlocking with that portion of the metal piece lying intermediate of
the bent back portions, substantially as set forth.
Second. A chain link baving the end portions of the metal piece bent back and
overlapping each other, the extreme ends thereof being bent about that portion
of the metal piece that is intermediate of the bent back portions, substantially as set
forth.
Third. A chain link having the ends of the metal piece bent back and over-
lapping each other, and having a shoulder formed in that portion of the metal
piece located intermediato of the said bent back portions, the extremities of said
ends interlocking with said shoulder, substantially as set forth.
Fourth. A chain link having the ends of the metal piece bent back and over-
lapping each other, and respectively interlocking by loops with that portion of the
metal piece lying intermediate of the said bent back portions, each interlocking
loop located further from the end of the link from which it was bent than is the
companion interlocking loop, substantially as set forth.
Fifth. A chain link having the ends of the metal piece bent back and over-
lapping each other, and having a shoulder formed in that portion of the metal
piece located intermediate of the bent back portions, the said bent back portions
interlocking by loops respectively with opposite faces of the said shoulder, each inter-
locking loop located further from the end of the link from which it was bent than
is the companion interlocking loop, substantially as set forth.
