Improvements in Carding Engines.
We, ASA LEES AND COMPANY LIMITED, of Soho Iron Works, Oldham,
in the County of Lancaster, Machine Makers, and JAMES ELISHA CHEETHAM,
of Soho Iron Works aforesaid Foreman, 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 carding engines and our improvements
consist in an improved arrangement for reversing the direction of rotation of the
main cylinder of a carding engine and driving it at about the same speed as when
carding whilst the wire surface thereon is being ground and without crossing the
driving belt.
In the accompanying two sheets of drawings-
Figure 1 is a side elevation of the main cylinder and doffer of a carding
engine to which our improved arrangement is applied, and Fig. 2 is a plan of the
same.
In these views, a designates the side framing, 6 the main cylinder, c its shaft,
d the fast pulley, e the loose pulley, the driving belt, g the doffer, and hits shaft.
The loose pulley e has a grooved pulley & formed with or secured to it and a
crossed rope i passes from this pulley el to the first groove of a three grooved
pulley which is fixed on the doffer shaft 1. From the second and third grooves
of the pulley ropes kl pass respectively to pulleys mn fixed on the axles op of
the grinding rollers qr of which the former grinds the wire surface of the main
cylinder 6 and the latter that of the doffer g. This arrangement for transmitting
motion to the grinding rollers qr is preferably duplicated at the other end of the
doffer shaft h upon which is also fixed the pulleys connected by a belt t with a
pulley u fixed on the main cylinder shaft o. Whilst carding the main cylinder bis
driven by the belt on the fast pulley d, the crossed rope i is taken away as is
also the strap t and the doffer g is driven in the usual well known manner from the
taker-in. Whilst grinding however, the crossed rope i is used to connect the
grooved pulleys e and j after the helt f has been moved over to the loose pulley e
so as to drive the doffer g grinding rollers qr and the main cylinder b all in the
direction indicated by the arrows, the main cylinder now being driven from the
doffer by means of the pulley a belt t and pulley u.
By this arrangement we are able to reverse the direction of rotation of the main
cylinder and drive it whilst grinding at the same or approximately the same quick
speed as when carding and without having to cross the driving belt.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. In combination, the fast and loose pulleys de, the driving belt f, the grooved
pulley e, crossed rope i, grooved pulley j, pulleys; belt and pulley u and
means for driving the grinding rollers qr from the doffer shaft all substantially in
the manner and for the purposes herein described with reference to the
accompanying drawings.
2. The general combination of parts constituting an improved arrangement for

whilst grinding and at approximately the same quick speed as whilst carding
without having to cross the driving belt substantially as herein set forth.
