page_text: Date claimed for Patent under Sect. 103 of Act,
being date of first Foreign Application (in 25th July, 1894
France),
I, EUGENE ROBERGEL, of La Guéroulde, (Eure), in the Republic of France,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in the manufacture of chains.
In order to make myself well understood I have shown in the accompanying
drawing, as an example only, a method of carrying my said invention into practice.
In the drawing
Figure 1 shows the first phase of the manufacture of a link.
Figure 2 shows the second phase of the manufacture of such link.
Figure 3 shows the third phase of the manufacture of the said link.
"F
Figure 4 shows the method of connecting a finished link with the next link in
process of manufacture.
Figure 5 shows, in front and side views, a piece of chain made according to my
said invention.
Like letters indicate corresponding parts throughout the drawing.
I will now describe the successive phases or steps in the formation of a link.
As shown in the drawing, the wire a, after having been cut to a suitable length,
is bent so as to form a fork as shown in Figure 1.
The end of the branch or limb b of the fork is then bent so as to form a ring, as
shown in Figure 2; the end of the branch or limb c is also bent to form a ring
which is placed in juxtaposition with that formed by the end of the branch or
limb b, as shown in Figure 3.
When the link is thus formed, a fresh fork is introduced into the rings as shown
in Figure 4 and rings are then formed at the ends of the branches or prongs of
this fork as above mentioned.
It will be understood that the number of links, as well as their dimensions, may
be varied according to the length of chain desired and to the tensile stresses which
the said chain is intended to withstand.
When all the links forming the chain are connected together as above mentioned,
I hold fast one of the ends of the chain and impart a movement of rotation to the
other end so as to twist the links as shown in Figure 5. This torsion may also be
effected by simultaneously turning the ends of the chain in opposite directions.

page_text: It must be understood that, instead of being formed from round wire, each of the
links may be formed of metal of any other transverse section, such as square,
rectangular, flat, ovoid, etc., and having a smooth or facetted surface.
I can make the links forming my improved chain either by hand or mechanically
without departing from the nature of my said invention.

I, EUGENE ROBERGEL, of La Guéroulde, (Eure), in the Republic of France,
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 relates to improvements in the manufacture of chains.
The following description will be readily understood by referring to the drawing
filed with my Provisional Specification in which I have shown, as an example only,
a method of carrying my said invention into practice.
In the said drawing
__
Figure 1 shows the first phase of the manufacture of a link.
Figure 2 shows the second phase of the manufacture of such link.
Figure 3 shows the third phase of the manufacture of the said link.
Figure 4 shows the method of connecting a finished link with the next link in
process of manufacture.
Figure 5 shows, in front and side views, a piece of chain made according to my
said invention.
Like letters indicate corresponding parts throughout the drawing.
I will now describe the successive phases or steps in the formation of a link.
As shown in the drawing, the wire a, after having been cut to a suitable length,
is bent so as to form a fork as shown in Figure 1.
The end of the branch or limb of the fork is then bent so as to form a ring, as
shown in Figure 2; the end of the branch or limb c is also bent to form a ring
which is placed in juxtaposition with that formed by the end of the branch or
limb b, as shown in Figure 3.
When the link is thus formed, a fresh fork is introduced into the rings as shown
in Figure 4 and rings are then formed at the ends of the branches or prongs of this
fork as above mentioned.
It will be understood that the number of links, as well as their dimensions, may
be varied according to the length of chain desired and to the tensile stresses which
the said chain is intended to withstand.
When all the links forming the chain are connected together as above mentioned,
I hold fast one of the ends of the chain and impart a movement of rotation to the
other end so as to twist the links as shown in Figure 5. This torsion may also be
effected by simultaneously turning the ends of the chain in opposite directions.

tion, and in what manner the same is to be performed, I declare that what I
claim is :-
The manufacture of the improved chain substantially as herein before described.
