COMPLETE SPECIFICATION.
Improvements in Carding Engines.
We, ASA LEES and COMPANY LIMITED, of Soho Iron Works, Oldham, in the
County of Lancaster, Machine Makers, and CHARLES EDWARD BARDSLEY, of the
same address, Under Foreman of the Carding Department, 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 improvements in carding engines and the object of
the invention is to construct a simple and quick means for giving the doffing
cylinder a second and slow motion so that the operative can readily change or
reduce the speed for a moment while piecing the sliver and then set the doffer
on again at the normal speed with very little loss of time.
In the accompanying three sheets of drawings--
Fig. 1 is a side elevation of part of the frame of a carding engine showing
the improved arrangement of gearing for driving the doffing cylinder at two
speeds, Fig. 2 is a plan and Fig. 3 an end view of Fig. 1.
In the drawings, 2 denotes part of one side or frame of a carding engine,
3 the pedestal and 4 the axle of the doffing cylinder on which is secured a spur
wheel 5, by which the doffing cylinder is driven; to an arm 6 pivoted to the
frame at 7, is secured a stud 8 upon which is mounted a pair of driving
pulleys 9 and 10 actuated by a belt 11, the pulley 9 being loose upon the stud 8
and the pulley 10 being loose upon the boss of the pulley 9. On the boss of
the pulley 10, see Fig. 3, is secured a pinion 12 gearing into a carrier wheel 13.
which gears into an extra wide carrier wheel 14 which also gears into a wheel 15,
on the boss of which is secured a pinion 16 which is in gear with and gives
motion to the wheel 5 and the doffing cylinder at its slow speed.
On the boss of the pulley 9 is secured a pinion 17 which is also in gear with
the wheel 15 and drives the doffing cylinder at its quick speed when the belt
is on the pulley 9.
to
The position of the driving belt 11 is controlled by a treadle and lever 18
pivoted at 19 to a bracket 20, an extension of the lever 18 being connected to
an arm 21 secured to the end of a shaft 22 which supports a weight 23;
the other end of the shaft 22 is secured, an arm 24 which carries a pin 25
lying in a slot in a lever 26 pivoted to a stud 27 supported in a bracket 28
carried by the frame; to the stud 27 is securèd a strap guide fork 29, which
is limited in its movements and is supported in either of its positions by studs 30
in the bracket 28.
The drawings represent the treadle 18 held in its highest position by the
weight 23 and when it is desired to move the belt 11 from the pulley 9 to the
pulley 10, and so change from the quick to the slow speed, the operative puts
his foot on the treadle and depresses it thus turning the shaft 22 on its axis,
lifting the weight 23 and simultaneously by the connections described moving
the strap guide fork 29 and shifting the belt 11 on to the pulley 10 when the
doffing cylinder will be driven direct by the wheels 12 13, 14, 15, 16 and 5 at

page_text: the slower speed, the treadle lever being latched by a hooked catch 31 pivoted
to the bracket 20.
To put the quick speed into gear again say after the sliver has been pieced it
is only necessary for the operative to push with his foot a projection 32 which
releases the catch 31 when the weight 23 will immediately turn the shaft 22
and move the strap fork and cause the belt '11 to move from the pulley 10 to
the pulley 9 and so drive the doffer cylinder at the quick speed by the
gears 17, 15 and 5.
!
The gearing is shown carried by the pivoted arm 5, provision being made for
adjusting the centres of the different wheels.
In the arrangement of mechanism shown and described the doffer cylinder is
driven by an independent belt 11 so that when the carding engine is in motion
the doffer will also be driven, and both its pulleys 9 and 10 will be in motion,
the belt 11 driving one pulley and the other being driven, in the same direction.
by the train of wheels which is not driving the doffing cylinder.
Although we prefer to employ the treadle mechanism described we wish it to
be understood that any suitable means may be employed for moving the strap
guide fork and the belt 11.
Having now particularly described and ascertained the nature of this said
invention and in what manner the same is to be performed we declare that what
we claim is:-
1. The arrangement, use and application of a single belt and two driving pulleys
combined with two trains of wheels for giving different speeds to the doffing
cylinder of a carding engine substantially as herein described and as set forth.
2. The arrangement, use and application of a single driving belt, two driving
pulleys and trains of wheels combined with suitable mechanism for actuating. the
strap guide fork and changing the speed of the doffing cylinder of a carding
engine substantially as herein described and as set forth.
3. The general construction, combination and arrangement of parts forming
the improved mechanism for driving the doffing cylinder of a carding engine at
different specds substantially as herein described and ás set forth.
Dated this 2nd day of March 1899.
