BARNSLEY BENNETT-2 Villa Rd Handsworth, Birmingham-Agent-do hereby declare
the nature of this invention to be as follows<-
The object of our improvements in driving chains, for use upon cycles, & general
machines, for driving purposes is to make a chain, light & strong-by forming
from one longitudinal piece of sheet metal, The two side plates, & making one
complete links, used in the chain-with its bent shaped centre, for bearing purposes,
upon the recesses of the cog wheel, between the teeth.-In carrying out our
improvements in driving chains, we cut from a sheet of steel or other required metal
a longitudinal piece therefrom, & fold the same at its centre, & also we pierce two
holes in cach side of the link, to receive the rivets & a roller, & for connecting
purposes.
Operation We connect this link (when the same has past through its
manufacturing stages) one after another to form the chain-with their rivets &
rollers for the purposes set forth.

ALBERT BAGSHAW Bk 86 Park Lane. Aston Birmingham. Jeweller & JOHN TYLER
BARNSLEY BENNETT 2 Villa Road, Handsworth Agent-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:-
The object of our improvements in driving chains for use upon cycles & general
machine, for driving purposes is to make a chain light & strong, by forming from one
longitudinal piece of steel metal, the two side plates, & making the one complete
link, used in a chain.
In carrying out our improvements, in driving chains, we cut, from a sheet of
steel, or other required metal, a longitudinal piece therefrom-& fold the samo at ita
centre, which has a square tongue formed on it, also we pierce, two, or more hole's
in each side link, to receive the rivets. & forward roller. & also we provide side link's
for connecting purposes.

page_text: Operation We connect, this folded link, (when the same has passed through its
manufacturing stages) one after another. to form the chain, with the rivets & roller's
& the side link's when required for the purposes set forth.
In order that our invention, may be fully understood we will more particularly
describe it, with the aid, of the accompanying drawing, in which similar parts are
marked, with like letter, of reference.
Fig. 1. Represents an elevation, of the small blank, of the folded link, & showing
the centre square.
Fig. 2. Represents a side elevation, of the small folded link.
Fig. 3. Represents a plan, of the small folded link's & side link's & rivet's forming
part of a chain.
Fig. 4. Represents an elevation, of the large blank, of the folded link & with
the tongue.
Fig. 5. Represents a side elevation, of the large folded link. & cranked end's of
link, & a single roller-within the link.
Fig. 6. Represents a side elevation, of the large folded link's, jointed together. &
carrying roller's & rivets. forming part of a chain.
Fig. 7. Represents in elevation, a chain, upon a Sprocket Wheel, formed by the
large folded link's. with a section, of the folded link's removed, & showing forward
roller's upon the teeth, of, the sprocket wheel.

We find by experiment, that the back pedalling, the action of the back of the
link 6. on the back side of the teeth. of the sprocket wheel's, causes the chain to act,
as a brake.
Having now particularly described, & ascertained the nature of our said, Invention
& in what manner, the same is to be performed, we declare, that what we claim is-
1st. A folded link, used in a chain, having a somewhat square centre, & two side
link's to act, as a brake, in forming a driving chain-as described, & set forth, &
ilustrated in the accompanying drawings.
2nd. The arrangements, & combinations of the folded link, with other part's as
shown at fig. 3. and described.
