Improvements in and in the Manufacture of Metallic Chains and
Cables.
We, EUGENE GEORGE CAMELINAT, of 31, Murdock Road, Handsworth, near
the City of Birmingham, Metal Spinner, and PAUL TAILLANDIER, of 9, The
Grove, Villa Road, Handsworth, aforesaid, Enamel Painter, do hereby declare
the nature of this invention to be as follows:-
This invention has relation principally to weldless metallic chain and cables,
and has for its primary object, to reduce the cost of manufacture and increase
the strength of such chain.
The invention refers to that particular type of weldless cable or chain in
which the links are formed from blanks having eyed ends and which is coupled
with the last formed link by being passed or threaded through the coincident
eyes of the same, and then folded over at the middle of the shank upon itself,
with the end eyes being closed down upon one another, alike unto the pre-
ceding link, to form a loop through which the shank of another blank is passed
and so on until a chain having the required number of links is produced.
In carrying out our improved method of producing weldless chain, we take a
series of blank from which a number of links are made, each blank consisting
of a round-section middle part or shank, terminated at its ends by eyes or loops,
lying in the same plane and preferably of about one half of the length of the
link to be made. The metal of one eye or loop is cupped or channelled on the
top side, or is made of a trough section, whilst the top side of the eye at the
other end of the shank is convexed, swelled or beaded to such a section as will
lie and fit cup-like within the corresponding she-channel of the first named
eye when the two eyes are brought together by folding over the blank upon the
middle of its shank and is thereby secured by gathering the edges of the metal
of the channelled eye around the metal of the other eye, thereby forming a
lock-joint weldless link, having two eyes at right angles to each other, but which
may be brought practically into the same plane by twisting.
A weldless chain is built up from a succession of such links by passing a
blank endwise through that loop formed by the closing together of the eyed
portions of the last formed link and then bending the blank at the middle to
cause the eyes to coincide, when they are then closed together as before.
Another blank is added and fashioned into a link in the same way, and so on
until a chain of the desired length is produced.
Although we have described that the over-lapping eyed ends of the blank are
secured or lock-jointed by closing the edges of the one around the solid metal

page_text: of the other, yet the said overlapping parts may be secured together by any
other method, such as by welding or rivetting.

Improvements in and in the Manufacture of Metallic Chains and
Cables..
We, EUGENE GEORGE CAMELINAT, of 31, Murdock Road, Handsworth, near
the City of Birmingham, Metal Spinner, and PAUL TAILLANDIER, of 289, St.
Vincent Street, Ladywood, Birmingham, and late of 9, The Grove, Villa Road,
Handsworth, near Birmingham, aforesaid, Enamel Painter, 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 metallic chain and cable and also to the production
of the chain principally of that type in which pierced-ended blanks are folded
nearly upon themselves about their middles so as to bring the said pierced ends
coincident and through which the next link blank is passed or threaded prior
to being folded upon itself in like manner to preceding link. The principal
object of our invention is to provide a weldless lock connection for the brought
together pierced ends or eyes of the link blanks, and also to produce chain
which, when made up, resembles an ordinary flexible chain or cable in which
the alternate links are at right angles to the intermediate ones.
Figure 1 of the accompanying drawings represents an elevation of a short
length of cable chain comprising a series of rigid twin links and made up from
a number of blanks, which are first folded about their middle nearly upon
themselves and then threaded in succession through the outer eye of the last
formed link, with the brought-together pierced ends of the folded blanks after-
wards locked up by a he-formed part of the end socketting into a she-part of
the other, in accordance with our invention.
Figure 2 is a plan of a blank from which a rigid twin link embodying our
improvements is formed.
Figure 3 is a longitudinal vertical section of the blank but with the middle or
fetter part in elevation.
Figure 4 is an edge view of the said blank.
Figure 5 is a cross section of the one end of the blank upon the dotted
line x.
Figure 6 is a like section of the other end upon the dotted line ..
Figure 7 represents a rigid twin link made from the said blank and pro-
duced by folding the fetter part about its middle so as to bring the looped ends
opposite to but separate from each other so as to admit of the passing of one
of them through the end eye of a previously coupled-up link.
Figure 8 represents the said link Figure 7 partly in vertical section and
partly in elevation.
Figure 9 represents a section of Figure 7 upon the full line 3, looking in
the direction of the full arrow, showing the bottom eye in plan.
Figure 10 represents a section also upon the dotted line, Figure 7, but

page_text: looking in the direction indicated by the dotted arrow, showing the upper
eye in plan.
Figure 11 is a complete longitudinal vertical section of two of the said rigid
twin links coupled together.
Figure 12 is a cross section of Figure 11 upon the dotted line 3, and looking
in the direction indicated by the arrow.
The same letters of reference indicate corresponding parts in Figure 1 to 12
of the drawings.
The blank represented in Figure 2 to 6 is fashioned preferably from steel
and preferably by drop stamping by taking a piece of metal and when in a
heated and soft state operating upon the same between dies.
a is the set-down shank or fetter of the blank, terminated at one end by a
rigid and annularly-cupped loop a', the trough of which is adapted to receive
socket-wise within it the solid annular loop or eye a³, at the other end of the
fetter, which said solid loop is locked within its seating by the turning or
closing of the edges a³, as, of the cupped loop partly over the outside and
inside boundary edges of the solid loop, less the projecting part a³, thereby
coupling the one loop to the other without welding and forming the complete
twin link (as represented in chain form in Figures 1, 11 and 12) having no
cross seams, liable to be opened by the pull or strain which comes upon chain.
By dropping or setting down the shank bar or fetter a, of the blank to a
lower or dis-similar plane than that of the looped ends to an extent equal to
one half the breadth of an eye, the said shank admits of being folded into a
link, coming at right angles to, and of the same figure as, the link formed by
the bringing together of the opposite eyed ends a¹, a².
It is understood that the ends of the dropped or set-down fetter bar or shank
come and terminate at the back or underside of the ends of the loops so as to
give the correct figure to the link formed from the said fetter bar.
An
Assuming that a length of chain, such as represented in Figures 1 to 11, is
to be made up, then a blank as in Figures 1 to 4 is taken and made as pre-
viously described into a complete twin link as marked A in Figure 1.
open link such as represented in Figure 7 and made by the partially folding
of a blank upon itself, is then taken and the end eye a³, thereof is then threaded
through the eye b, of the complete link A, after which the eyes a¹ and 2 are
closed together and made to socket one into the other and then the boundary
edging of the cupped end is closed over the adjacent metal of the solid loop,
thereby locking the loop to the other and completing the second twin link. A
third link is added to the second in the same manner and so on, until a chain
of the desired length is obtained.
The turning and closing over of the edges of the cup sectioned eye over the
solid eye seated within it is performed by closing tools.
In some cases, the opposed faces of the brought-together looped ends may be
welded, thereby producing a solid homogeneous link without any welded seams
crossing the direction of and liable to be opened by the pull that comes upon
the chain.
Before the U-shaped links are assembled into a length of chain we propose to
galvanize them or otherwise cover them with a protective coating of metal.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim is:-
First The manufacture of chain or cable from blanks having eyed or
looped terminations, one of which is made to socket or cup within the other,
substantially as herein described and set forth.
Secondly: The manufacture of chain or cable from blanks having eyed or
looped terminations such as a', a², with a set-down or dropped shank such
as a, intervening between the said eyed terminations, locked together by the

page_text: socketting or cupping of the one within the other, substantially as described
and set forth.
Thirdly Chain or cable formed from blanks having eyed or looped ends
such as a, a, with a set-down or dropped shank such as a, intervening between
the said ends, one of which sockets or cups within the other for locking and is
there coupled by the turning or closing over of the metal of the trough-
sectioned eye, substantially as described and set forth.
