Improvements in the Manufacture of Driving or Gearing Chains
suitable for Bicycles, Tricycles, and other like Articles, and for
Machinery in General.
I RICHARD GREEN of Cromwell Street, Earlsdon, near Coventry, in the County
of Warwick, Mechanician do hereby declare the nature of this invention to be as
follows:
Its advantages over the chains already in use, are that it is stronger,, lighter and
more economical of production.
The chain consists of a number of links of two different patterns, one being an
ordinary perforated link for the teeth of the wheel to work in and the other a
connecting link for the purpose of connecting the ordinary links together to form
the chain.
The cheif novelty and advantage is that each link is made in one piece out of sheet
metal by means of presswork or by other suitable methods.
The ordinary perforated link is first cut out in outline in the form of a blank, after
which it is pierced and then the two opposite ends are rounded to form the spindle for
the connecting link to work on..
The connecting link connects two of the ordinary links together, it is first cut out
of a piece of sheet metal in the form of a flat blank after which it is bent over and the
two ordinary links threaded through in their proper positions, when the two ends are
closed and fastened either by a dovetail, solder, or other suitable joint.
Thus it will be percieved that the ordinary link is simply a piece of sheet metal
perforated, in one piece, and without joinings.
The connecting link is a single piece of sheet metal made to clasp two of the
ordinary links and being bent round until the two ends meet to form the joining.

page_text: I, RICHARD GREEN of Cromwell Street, Earlsdon, near Coventry, in the county of
Warwick, Mechanician 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 :-
In the accompanying drawings figs. 1, 2, & 3, shew the process of manufacturing
the ordinary link.
Figs. 4, 5, & 6 shew the process of manufacturing the connecting link.
The chain consists of a number of links of two different patterns, one being an
ordinary perforated link (as shown in fig. 3) for the teeth of the wheel to work in, and
the other a connecting link (as shewn at A fig. 6) for the purpose of connecting the
ordinary links together to form a chain.
The ordinary perforated link is first cut out in outline in the form of a blank as
shewn in fig. 1, after which it is pierced as shewn in Fig. 2 and then the two opposite
ends are rounded to form the spindle for the connecting link to work on as shown in
fig. 3.
The connecting link connects two of the ordinary links together; it is first cut out
of a piece of sheet metal in the form of a flat blank as shewn in fig. 4, after which it
is bent over and the two ordinary links threaded through in their proper positions as
shewn in fig. 5 when the two ends are closed and fastened either by a dovetail,
solder, or other suitable joint as shewn at A fig. 6.
Thus it will be perceived that the ordinary link is simply a piece of sheet metal
perforated, in one piece, and without joinings.
The connecting link is a single piece of sheet metal made to clasp two of the
ordinary links and being bent round until the two ends meet to form the joining.
The chief novelty is that each link is made in one piece of sheet metal by means
of presswork or other suitable methods, thus ensuring a lighter chain possessing
greater strength at a less cost than the ordinary one.
The connecting link may also be used in combination with the ordinary link as
shewn in fig. 7.

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 :—.
1. The solid link stamped out of sheet metal in one piece having the two opposite
sides rounded by presswork or machinery for working in the connecting link as
hereinbefore described.
2. The connecting link stamped out of sheet metal in one piece and closed over
and suitably joined by presswork or machinery, by means of a dovetailed, soldered
or other suitable joint as herein before described.
3. The making of a chain by means of the connecting link and the solid link as
herein before described and illustrated by the acccompanying drawings.
