COMPLETE SPECIFICATION.
An Improved Drive-chain Link.
We, SAMUEL H. VINSON, and HORTON H. HANNA, both of Dayton, Ohio,
U.S.A., Inventors 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 :-
Our invention relates to improvements in drive-chains, the features of which will
be fully hereinafter described and claimed.
The object of our invention is to construct a drive-chain from blanks cut out
of sheet metal, and after forming said blanks one is interlocked with its fellow
in the formation of a chain. The construction is illustrated in the accompanying
drawings, in which :-
Fig. 1 is a view of the blank as cut from a sheet of metal.
Fig. 2 is a side view of two links as united in the formation of a chain.
Like letters and numerals designate like parts in the two views. The blank A
is cut out of sheet metal having parallel sides forming the body a central portion 2,
bent into a circular form square orifices 4 and 5 and the ends 1 and 3 bent in the
form of a hook and adapted to enter the orifice of a like link and embrace circular
part.
B Fig. 2 illustrates the link as formed from the blank the circular end 2 and on
the other end the hook of parts 1 and 3. The fellow link C is identical in forma-
tion, is placed in the position C' (indicated by dotted lines) and is pressed within
the hook of the former until the hook and central orifice are coincident, and
then by turning to the right the links are securely interlocked, and thereby forming
a drive-chain.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:-
A drive-chain link formed from a blank of sheet metal having a central rib, an
opening on each side of the central rib and ends of less width than the body of the
blank, said link comprising a cylindrical end formed from the central rib of the

page_text: blank bent upon itself, a body portion having a central opening, and a hook
formed by the ends of the blank curved in the same direction, substantially as
described.
