Improvements in Driving Chain for Velocipedes and other Chain
Driven Carriages.
We, GEORGE NEWEY, of No. 123 Lennox Street, Lozells, near Birmingham, in the
County of Warwick, Machinist, and FRANK HULSE of No. 133 Waverley Road, Small
Heath, Birmingham, aforesaid, Manager do hereby declare the nature of this Invention
to be as follows:-
Our invention has reference to driving chain for velocipedes and other chain driven
carriages of the kind known in commerce as roller chain; and our said invention
consists of the improvements hereinafter described in constructing the roller carrying
links, that is, the inner and intermediate links, of the chain, whereby the manufacture
of the chain is simplified and economized.
In the ordinary methods of making the said roller carrying links a pair of side
plates connected together by a pair of rivetted tubes or bushes between them have
been employed. Or in place of the said bushes a pair of tubular bosses of half the
width of the rollers and in one piece with each of the side plates of the link have
been employed; or one end of each of the side plates of the link has been provided
with a tubular boss of about the width of the roller, the other end of each side plate
being pierced with a hole or eye which takes upon the boss opposite which it is
situated when the two side plates of the link are brought together with their bosses
between them.
According to our invention we make upon one of the side plates of the roller
carrying links of the chain and at each end of the said plate a tubular boss solid with
the plate itself and of rather more than the width of the roller and we make the
other side plate of the link, flat or plain and without tubular bosses, the said flat side
plate being pierced at its ends with holes or piercings having such a size and position
that when the two side plates are brought together the said holes or piercings will fit
upon reduced parts or shoulders on the ends of the tubular bosses. The shoulders
serve as abutments for the said plain side of the link when it is pressed upon the
tubular bosses on the other side plate of the link after the rollers have been placed in
position upon the said bosses.
Each of the roller carrying links is thus composed of a side plate having at each
end of its inner face a tubular boss and a second plain side plate pierced at its ends
but without tubular bosses.
The inner or roller carrying links and the outer flat links of the chain are jointed
together by rivets passed through the tubular bosses of the roller carrying or inner
links and riveted outside the outer links as usual.
Driving chain constructed according to our invention may be used in connection
with roller chain wheels and with block chain wheels, the links being pitched or
spaced to suit the particular kind of chain wheel with which they are to be used. In

page_text: making our improved roller chain for use with block chain wheels we make the chain
with alternating long and short links suitably pitched or spaced, the longer links
being the inside links and carrying the rollers and the shorter links the outside links.

Improvements in Driving Chain for Velocipedes and other Chain
Driven Carriages.
We, GEORGE NEWEY of No. 123 Lennox Street, Lozells near Birmingham in the
County of Warwick Machinist, and FRANK HULSE of No. 133 Waverley Road, Small
Heath, Birmingham, aforesaid Manager, do hereby declare the nature of our 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 has reference to driving chain for velocipedes and other chain driven
carriages of the kind known in commerce as roller chain; and our said invention
consists of the improvements bereinafter described in constructing the roller carrying
links, that is, the inner and intermediate links of the chain, whereby the manufacture
of the chain is simplified and economized.
In the ordinary methods of making the said roller-carrying links, a pair of side
plates connected together by a pair of tubes or bushes between them have been
employed. Or in place of the said bushes, a pair of tubular bosses of half the width
of the rollers and in one piece with each of the side plates of the link have been
employed; or one end of each of the side plates of the link has been provided with a
tubular boss of rather more than the width of the roller, the other end of each side
plate being pierced with a hole or eye which takes upon the boss opposite which it is
situated when the two side plates of the link are brought together with their bosses
between them.
According to our invention we make upon one of the side plates of the roller-
carrying links of the chain and at each end of the said plate, a tubular boss solid
with the plate itself and of rather more than the width of the roller, and we make
the other side plate of the link, flat or plain and without tubular bosses, the said flat
side plate being pierced at its ends with holes or piercings having such a size and
position that when the two side plates are brought together, the said holes or
piercings will fit upon reduced parts or sboulders on the ends of the tubular bosses.
These shoulders serve as abutments for the said plain side of the link when it is
pressed upon the tubular bosses on the other side plate of the link after the rollers
have been placed in position upon the said bosses.
Each of the said roller-carrying links is thus composed of a side plate having at
each end of its inner face a tubular boss and a second side plate pierced at its ends
but without tubular bosses. The inner or roller carrying links and the outer flat
links of the chain are jointed together by rivets passed through the tubular bosses of
the roller carrying or inner links and rivetted outside the outer links as usual.
Driving chain constructed according to our invention may be used in connection
with "roller" chain wheels and with "block" chain wheels, the links being pitched
or spaced to suit the particular kind of chain wheel with which they are to be used,

page_text: In making our improved roller chain for use with "block" chain wheels we make the
chain with alternating long and short links suitably pitched or spaced, the longer
links being the inside links and carrying the rollers and the shorter links the outside
links.
Figure 1 of the accompanying Drawing represents in longitudinal section the side
plates of a roller carrying link constructed according to our invention; Figure 2
represents in longitudinal section and Figure 3 in side elevation a portion of a driving
chain for use with ordinary roller chain wheels, the said chain being composed of inner
or roller carrying links, constructed according to our invention, and of ordinary outer
links rivetted together as hereinafter described; Figure 4 represents a portion of a
roller chain wheel provided with teeth suitable for the chain Figures 2 and 3.
The side plates of which each of the inner or roller carrying links is made, are
marked a and b. The side plate a has on its inner face and at each end thereof, a
tubular boss marked a², the said bosses being made solid with the said plate. These
tubular bosses are a little wider than the rollers to be used on them. At the ends of
the bosses a², a2 are reduced parts or shoulders or abutments marked a³, a³. The
other side plate & of the link is without tubular bosses but its ends are pierced with
holes b, for fitting upon the reduced ends, shoulders or abutments , as of the
bosses a, a of the side plate a; c, c are the ordinary outer plates or links of the chain
pierced at their ends for receiving the joint pins or rivets; d, d are the loose rollers.
working on the tubular bosses a², a² of the roller carrying links.
In fitting and jointing the links together, the rollers d, d are placed on the tabular
bosses a, a of the side plate a and the two side plates a, b are fitted together by the
engagement of the perforated ends of the side plate b with the shoulders or
abutments a³, a3 of the bosses of the other side plate a. The roller or inner links a, b
and the outer links c, c are then jointed together by the rivets e, e passed through the
tubular bosses a, a of the roller carrying links and rivetted outside the outer
links e, e as represented in the drawing."
Figure 5 represents in longitudinal section and Figure 6 in side elevation, a driving
chain constructed according to our invention to be used with block chain wheels and
Figure 7 represents a portion of a block chain wheel the teeth of which are suitable
to receive the links of the chain Figures 5 and 6; Figure 8 represents in section the
plates detached constituting one of the inner or roller-carrying links of the chain
Figures 5 and 6.
The parts of this chain are substantially the same as those of the chain
Figures 1, 2 and 3 already described and corresponding parts are marked with the
same letters of reference, but it will be seen that this chain is composed of alternating
long inner or roller-carrying links a, b and short outer links e, e the said links a, b
and e being so pitched or spaced that the teeth, on the block chain wheel Figure 7,
work within the spaces f of the inner links a, b and between the two rollers carried by
the bosses of the said links. By constructing the inner or roller links of driving
chain according to our invention the manufacture of the chain is simplified and
economized and the bosses of the said inner or roller links afford continuous or
unbroken bearing surfaces for the whole width of the rollers as represented.
Having now particularly described and ascertained the nature of our invention
and the manner in which the same is to be performed we declare that we claim
as our Invention of "Improvements in driving chain for velocipedes and other
chain driven carriages."
Making each of the inner or roller carrying links of roller driving chain, of a side
plate having on its inner face and at each end thereof, a tubular boss slightly wider
than the roller to be fitted on it, the said tubular bosses being solid with the said
plate and having shoulders or abutments at their free ends, and of a second side plate,
plain or without tubular bosses, pierced at its ends with holes suitable for taking upon
the shoulders or against the abutments of the tubular bosses of the first named side
plate, the said inner or roller carrying links being jointed together and to the ordinary

page_text: outer links by rivets substantially as hereinbefore described and illustrated in the
accompanying Drawing.
