PROVISIONAL SPECIFICATION.
Improvements relating to Carding Engines.
WILLIAM HOPKINSON 2 Briggs Yard Accrington, Machine Fitter, RICHARD
TYACK 10 College Street Accrington, Machine Fitter, do hereby declare the
nature of this invention to be as follows:-
This invention relates to the driving mechanism of the carding engine doffer,
portions of which are shown in the Specification of Hitchon and Duckworth
No. 7002 A.D. 1895 to which we make reference.
At 24 and 25 Fig. 5 Sheet 2 is shown a pair of step or cone pulleys mounted on
the shaft end of the taker-in.
In our invention we make use of the two step or cone pulleys for the purpose of
driving through two belts alternately, which run at different speeds, the pulley to
which we fix rigidly the pinion wheel 5 which gears with doffer wheel 11 through
wheels 9 and 10.
A loose pulley is mounted on each side of the pinion wheel driving pulley so as
to allow for the shifting of either of the belts on to the aforesaid pinion wheel
driving pulley.
We mount the belt shipping guide forks of each belt in such relative positions
with the fixed driving pulley or pulleys and their corresponding loose pulleys so
that each driving belt or belts can be brought in driving position or on to the loose
pulley for the purpose of driving the doffer either at full speed, slow speed, or
letting the same remain at rest although the belt or belts may continue to run,
whereby our invention can be coupled up to the sliver stop motion of Vaughan and
others, Specification No. 11716 dated A.D. 1889 as referred to and illustrated in
Hitchou and Duckworth's Specification and for same like purposes.
As a modification for dispensing with one of the two belts as shown in the
aforesaid Hitchon and Duckworth's Specification, and retaining the use of the step
or cone pulleys 24 and 25, Fig. 5, Sheet 2, we provide betwixt the larger and lesser
part of such step or cone pulley or pulleys, a conical or bevel formation, so that a
single belt may be slid from the lesser to the larger diameters or the reverse.
A second correspondingly shaped pulley is mounted to the driving pinion wheel
with loose pulley in close proximity.

Improvements relating to Carding Engines.
WILLIAM HOPKINSON, 2 Briggs Yard Accrington, Machine Fitter, and
RICHARD TYACK, 10 College Street, Accrington, Machine Fitter, 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 relates to the driving mechanism of the carding engine doffer,

page_text: portions of which are shown in the Specification of Hitchon and Duckworth,
No. 7002 A.D. 1895, to which we make reference.
At 24 and 25 Fig. 5, Sheet 2, of the drawings filed with the prior specification is
shown a double driving pulley mounted on the shaft end of the taker-in.
invention we make use of the double driving pulley for the purpose of driving
through two belts alternately, which run at different speeds, the pulley to which
we fix rigidly the pinion wheel 5 which gears with doffer wheel 11 through
wheels 9 and 10.
A loose pulley is mounted on each side of the pinion wheel driving pulley so as
to allow for the shifting of either of the belts on to the aforesaid pinion wheel
driving pulley. We mount the belt shipping guide forks of each belt in such
relative positions with the fixed driving pulley or pulleys and their corresponding
loose pulleys so that each driving belt or belts can be brought in driving position
or on to the loose pulley for the purpose of driving the doffer either at full speed,
slow speed, although the belt or belts may continue to run.
And in order that our invention may be fully understood and readily carried
into effect, the accompanying sheet of drawings will serve to illustrate our invention,
and how the same is to be applied :-
Fig. 1 being a side elevation of a carding engine;
Fig. 2 being plan of same, with reference letters in keeping with each other on
both figures to define the parts in detail. A. and B. being the driving pulleys of
different diameters, causing the two driving belts to travel at two different rates of
speed, the double strap fork G having command of same. When the belt coming
from driving pulley A. is slid on pinion driving pulley E, the same will have a
certain revolving speed, and driving belt from the small driving puiley B, running
at a much slower speed, will be on loose pulley F. Therefore, when the slower
travelling belt is slid from the loose pulley F on to the aforesaid pinion pulley E,
the belt coming from the large driving pulley A will pass off pinion pulley E on to
loose pulley D, and at the same time the slow belt on loose pulley F will pass on
to driven pulley E, thus giving the necessary slow motion at will. Carrier lever C
is made use of for disengaging pinion wheel L from doffer wheel K, H being a
handle for operating the moving of strap fork motion G.
Having now particularly described and ascertained the nature of our said inveu-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
The improved mechanism as shown and described, operated by two driving belts
in combination with loose and fast pulleys operated by strap forks.
