Improvements in Driving Chains.
We, SAMUEL HERBERT BROOKS, of the firm of Brooks & Doxey, Union Iron
Works, West Gorton, in the County of Lancaster, Machine Makers, and THOMAS
GOODBEHERE, of the Union Iron Works aforesaid, Manager, do hereby declare
the nature of this invention to be as follows:-
This invention is intended to provide a driving chain for the tin rollers of
spinning and other frames which are driven in opposite directions at a high
speed, so constructed that it may be employed both internally and externally, or
that both sides can be utilized for engaging with the driving wheels. It will
also be applicable to other sets of rollers or mechanism to be driven alternately
or otherwise in opposite directions.
It refers to that class of driving chain in which the links are shaped with a
projection to engage with the driving wheel, and consists essentially in construct-
ing the chains of links formed on projections on both sides to form a double face
to the chain or in constructing the chain of links with a single face placed
alternately to face opposite ways to produce a chain with two faces either or both
of which can be utilized for driving purposes.
In carrying out the invention the links are stamped. or formed of an H shape
with projections at both ends at either side of the pin centres such projections
being preferably tapered or otherwise shaped to engage or gear with the driving
wheels. The chain is made up of any number of these links rivetted together.
In a modified form the links are formed at each end but at one side only and
the chain is made up of any number of such links rivetted together with the
projections placed alternately at one side or the other to give a double driving
face to the chain. .

page_text: 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 is intended to provide a driving chain for the tin rollers of
spinning and other frames which are driven in opposite directions at a high
speed, so constructed that it may be employed both internally and externally, or
that both sides can be utilized, for engaging with the driving wheels. It will
also be applicable to other sets of rollers or mechanism to be driven alternately
or otherwise in opposite directions.
It refers to that class of driving chain in which the links are shaped with a
projection to engage with the driving wheel, and consists essentially in construct-
ing the chains with projections on both sides to form a double face to the chain
either or both of which can be utilized for driving purposes.
The invention will be fully described with reference to the accompanying
drawings.

Fig. 2. Transverse sectional elevation of same on line < Fig. 1.
Fig. 3. Plan of same.
Fig. 4. Side elevation of single link.
Fig. 5. Side elevation of another form of the chain.
Fig. 6. Plan of same.
Fig. 7. Transverse section of same on line y-.
Fig. 8. Transverse section showing modified arrangement of links.
Fig. 9. Side elevation of single link.
Fig. 10. Elevation of end of spinning frame showing application of the
improved chain.
Fig. 11. Elevation of end of spinning frame showing another arrangement of
same.
Referring to Figs. 1 to 4 the links A of which the chain is constructed are
formed with projections a on both edges extending above and below the pin
centres giving to the links the form of the letter H. The projections a are
preferably tapered or otherwise shaped to engage or gear with the teeth of the
driving wheels.
Referring to Figs. 5 to 9, the links are formed as in Fig. 9, with the projec-
tions a at one side only, and the chain is made up of any number of such links
rivetted together with a proportion (preferably half) of the links set in one
direction, and the others projecting in the opposite direction to give a double
driving face to the chain. A washer or roller B is preferably placed between each
set of links.
We prefer to arrange the links of the chain such as shown in Figs. 6 and 7
with three rows of links to form a balanced chain, the centre set of links to drive
the wheel or wheels turning in one direction, the two outer sets to drive the
wheel or wheels turning in the reverse direction. The chain may, however, if
preferred be made of two sets of links placed side by side projecting in opposite
directions as shown in Fig. 8. Figs. 10 and 11 illustrate the application of the
chains.
We are aware that links such as shown in Fig. 9 have already been used for
constructing chains with a single driving face, and we do not make any claim to
such per se.
Taving now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is:
1. A driving chain constructed with projections on both sides to engage with
wheel teeth to form a double faced chain either or both of which faces can be
utilized for driving purposes, substantially as described.
2. A driving chain constructed of links with projections on both sides (such

page_text: as shown in Fig. 4) to provide two driving faces either or both of which can be
utilized, substantially as described and shown.
3. A driving chain constructed with double driving faces, substantially as
described and shown, with reference either to Figs. 1 to 4, Figs. 5 to 7, or to
Fig. 8 of the drawings.
