PROVISIONAL SPECIFICATION.
Improvements in Driving Chains.
We, SAM THOMAS RICHARDSON, of 3*, Rea Street, in the City of Birmingham,
Cycle Manufacturer, and ALFRED SMALLWOOD, of Globe Metal Works, Small-
heath, Birmingham, Metal Merchant, and RICHARD PRICE of 3^, Rea Street,
aforesaid, Cycle Manufacturer, do hereby declare the nature of this invention to be
as follows:
This invention consists of the hereindescribed improvements in the construction
of driving chains for transmitting power and motion for various purposes such as
in safety bicycles and other velocipedes, and for driving various parts of machinery
where driving chains are used.
In a driving chain constructed according to this invention the links are formed
as hereindescribed so as to be connected together without the use of separate
joint pins.
Our improved driving chain consists of hollow square or oblong shaped links
alternating and engaging with links which have the shape of the figure 8. Each
of the said hollow square or oblong links has two of its opposite sides somewhat
flat and its other two opposite sides round or somewhat round in cross section so
that these latter will form the joint pins, the four sides of the link being stamped
or otherwise formed together in one piece. The rounded sides of the said square
or oblong links pass through the eyes of the figure 8 links and work easily therein,
the figure 8 links being made of the proper width to fit easily between the sides of
the square or oblong links.
We may make these figure 8 links in two ways, that is to say we may first raise
or otherwise form them from sheet or strip metal in the form of the letter S leaving
the ends open for connecting to the square or oblong links and then we close these
ends on to the centre portion to complete the figure 8; or we may raise or other-
wise form the figure 8 links from sheet or strip metal somewhat like the figure 3
leaving the ends open for connecting to the square or oblong links and then we
close these ends down on to the central portion and complete the figure 8. The
figure 8 links may either be raised from sheet or strip metal by suitable press tools
or be otherwise formed.
Dated this 9th day of November 1894.

We, SAM THOMAS RICHARDSON, of 3 Rea Street, in the City of Birmingham,
Cycle Manufacturer, and ALFRED SMALLWOOD, of Globe Metal Works, Small-
heath, Birmingham,, Metal Merchant, and RICHARD PRICE, of 3 Rea Street,
aforesaid, Cycle 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:-
This invention consists of the hereindescribed improvements in the construction

page_text: of driving chains for transmitting power and motion for various purposes such as
in safety bicycles and other velocipedes, and for driving various parts of machinery
where driving chains are used.
In a driving chain constructed according to this invention the links are formed
as hereindescribed so as to be connected together without the use of separate
joint pins.
Our improved driving chain consists of hollow square or oblong shaped links A
alternating and engaging with links B' or B2 which have the shape of the figure 8.
Each of the hollow square or oblong links A has two of its opposite sides a¹ a²
somewhat flat and its other two opposite sides a³ a round or somewhat round in
cross section so that these latter will form the joint pins, the four sides of the
link being stamped or otherwise formed together in one piece. The rounded
sides as a of the square or oblong links A pass through the eyes 61 62 of the
figure 8 links B¹ or B2 and work easily therein, the figure 8 links being made
as shewn of the proper width to fit easily between the sides a¹ a³ of the square
or oblong links A.
We may make these figure 8 links.in two ways, that is to say, we may as shewn
by Fig. 4 first raise or otherwise form them from sheet or strip metal in the
form of the letter S leaving the ends 636 and eyes 6162 open for connecting
to the square or oblong links. A and, then when thus connected we close these
ends on to the centre portion 65 to complete the figure 8 as shewn in
Figs. 1 and 2; or as shewn in Fig. 7 we may raise or otherwise form the figure 8,
links from sheet or strip metal somewhat like the figure 3 leaving the ends open
for connecting to the square or oblong links A and then when thus connected we
close these ends b³ down. on to the central portion 66 and complete the figure 8 as.
shewn in Figs. 5 and 6. The figure 8 links B and B may either be raised from
sheet or strip metal by suitable press tools or be otherwise formed..
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 :-
The hereindescribed improved driving chain composed of hollow square or oblong
shaped links A alternating and engaging with links B' or B2 which are shaped and
formned to engage with the links A in either of the ways substantially as herein-
before described and illustrated by the accompanying drawing.
