purposes.
ALBERT BAGSHAW, Bk 86, Park Lane, Aston, Birmingham, Jeweller and JOHN
TYLER BARNSLEY BENNETT, 2, Villa Road, 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
machine, for driving purpose, has reference principle to the shape of the roller block,
which is made to fit, upon the tooth, or prong of the procket wheel or cog wheel, so
as to cover it, whereby a greater leverage in power is gained, & a firmer swinging
grip is obtained of the working parts. In carrying out our invention, we make a
roller block, somewhat in the shape of an arch, or part of a circle outside, and inside
concaved, so as to fall readily upon the tooth of the wheel, & grip it firmly. We
pierce the required holes, for riveting connecting the links & washers, so as to
form the chain. We use any required ordinary cog wheel or procket wheel, or any
class of side links, rivets, or washers.
Our improved arch roller block, may be cut from thin piece of steel, or other metal,
& a number placed together, the thickness for working over the teeth of the cog
wheel, or the arch roller block, inay be cut out in one thick piece, or it may be cast
in one piece, or it may be stamped from metal.
Dated this 27th day of November 1896.

ALBERT BAGSHAW Bk 86 Park Lane, Aston Birmingham Jeweller and 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 chain for use upon cycles & general
machine for driving purposes, has reference principle to the shape of the roller block,
which is made to fit upon the tooth or prong of the spocket or cog wheel, so as to
cover it like a cap whereby a greater leverage in power is gained & a firmer
swinging grip is obtained of the working parts. In carrying out our invention, we

page_text: make the roller block somewhat in the shape of an arch, or part of a circle out side
and inside concave, so as to fall readily upon the tooth of the wheel, & grip it firmly,
we pierce the required holes in for riveting & connecting the links & washers so
as to form a chain. Our improved arched roller block, may be cut out in thin pieces
of steel, or other metal, & a number placed together to form the thickness or cut
out in one piece, or cast, or stamped.
In order that our invention may be fully understood, we will more particularly
describe it, with the aid of the accompanying drawings in which similar parts are
marked with like letter of reference.
Fig. 1. Represents an elevation, of a block, of the arch chain.
Fig. 2. Represents an elevation of two arch block's connected to a side link.
Fig. 3. Represents an elevation of the arch block's in a chain, working on a driving
wheel, of a cycle, & showing the side link's removed, each arch block, fits like a cap
with the aid of the side link's each tooth of the sprocket wheel,
a, arch roller block, b, side link, for connecting purposes by rivet, washer or sleeve,
c teeth of the sprocket wheel.
Having now particularly described and ascertained the nature of our said
Invention, & in what manner the same is to be performed we declare that what we
claim is :
1st. An arch link block, connected with the link's to form a chain.
2ndly. An arch link block in a chain as set forth described and illustrated in the
accompanying drawings.
