We, LORD BROTHERS LIMITED, of Canal Street Works, Todmorden, in the
County of York, Machine Makers, and WALTER LORD and THOMAS GANDY MILLS,
Directors, and JOHN STOCKS, Foreman Card Fitter, all of the same address, do
hereby declare the nature of this invention to be as follows:
:-
Our invention relates to a novel combination and arrangement of parts for
transmitting the ordinary or quick speed as well as a second or slow speed to
the doffing cylinder of a carding engine.
In carrying our invention into effect the doffing cylinder is driven by a spur
wheel either directly or by a carrier wheel or wheels from a pinion mounted on
a stud carried by the side frame of the carding engine, and we mount two pulleys
of different diameters loosely on the boss of this pinion; between these two
pulleys we fix on the boss of the pinion a disc or plate with clutch teeth or equi-
valents on either side face and we form corresponding clutch teeth or equivalents
on the contiguous faces of the two pulleys.
The two pulleys are driven by a pair of bands or belts the larger pulley at the
slow speed and the smaller at the quick speed, and the half clutch on the quick
speed pulley is held normally in gear with the corresponding half clutch ou
the fast disc by means of an arrangement of clutch fork levers, to which is
connected a foot lever or treadle. The attendant by placing his foot on the
treadle and depressing it can throw the quick speed pulley out of gear and bring
the slow speed pulley into gear with the half clutch on the disc so that the doffer
will run at the slow speed whilst the attendant is piecing up and the parts are
so weighted or otherwise arranged that when the attendant takes his foot off
the treadle after piecing the broken sliver the quick speed pulley will automa-
tically move into gear and the doffer resume its normal or quick speed.
The parts are further so arranged that the treadle lever can be latched by a
spring bolt or catch in an intermediate position with both pulleys out of gear
with the fast clutch and when in this position the doffer will of course remain
stationary although its driving pinion still remains in gear as it is mounted upon
a fixed stud instead of being carried by the ordinary drop lever which is dis-
pensed with in this arrangement.

We, LORD BROTHERS LIMITED, of Canal Street Works, Todmorden, in the
County of York, Machine Makers, and WALTER LORD and THOMAS GANDY MILLS,
Directors, and JOHN STOCKS, Foreman Card Fitter, all of the same address, 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 follow-
ing statement:
-
Our invention relates to a novel combination and arrangement of parts for
transmitting the ordinary or quick speed as well as a second or slow speed to
the doffing cylinder of a carding engine.
In carrying our invention into effect the doffing cylinder is driven by a spur
wheel either directly or by a carrier wheel or wheels from a pinion mounted onl
a stud carried by the side frame of the carding engine, and we mount two pulleys
of different diameters loosely on the boss of this pinion; between these two
pulleys we fix on the boss of the pinion a disc or plate with clutch teeth or equi-
valents on either side face and we form corresponding clutch teeth or equivalents
on the contiguous faces of the two pulleys.
The two pulleys are driven by a pair of bands or belts, the larger pulley at the
slow speed and the smaller at the quick speed, and the half clutch on the quick
speed pulley is held normally in gear with the corresponding half clutch on
the fast disc by means of an arrangement of clutch fork levers, to which is
connected a foot lever or treadle. The attendant by placing his foot on the
treadle and depressing it can throw the quick speed pulley out of gear and bring
the slow speed pulley into gear with the half clutch on the disc so that the doffer
will run at the slow speed whilst the attendant is piecing up and the parts are
so weighted or otherwise arranged that when the attendant takes his foot off
the treadle after piecing the broken sliver the quick speed pulley will automa-
tically move into gear and the doffer resume its normal or quick speed.
The parts are further so arranged that the treadle lever can be latched by a
spring bolt or catch in an intermediate position with both pulleys out of gear
with the fast clutch and when in this position the doffer will of course remain
stationary although its driving pinion still remains in gear as it is mounted upon
a fixed stud instead of being carried by the ordinary drop lever which is dis-
pensed with in this arrangement.
In the accompanying two sheets of drawings-
Figure 1 is a side elevation of part of a carding engine to which our improve-
ments are applied, Figure 2 is a plan view of Fig. 1, partly in section, and
Figure 3 is an end view of the same.
In the drawings,-2 designates the side frame of the carding engine, and 3 the
shaft or axle of the doffing cylinder 4; upon the shaft 3 is secured the doffer
gear 5 and upon a stud 6 secured to the side frame is mounted a pair of carrier
wheels 7 and 8, the former gearing into the doffer wheel 5, and the latter gearing
into a pinion 9 loose upon a stud 10 secured to the side frame 2; on the boss
of this pinion 9 are mounted loosely two pulleys 11 and 12 of different diameters
and between these two pulleys upon the boss of the pinion is secured a disc or
plate 50 with clutch teeth or equivalents on either side face, and we form corre-
sponding clutch teeth or equivalents on the contiguous faces of the two
pulleys 11, 12.
The pulleys 11 and 12 are driven by a pair of bands, see Fig. 1, the larger
pulley 11 at the slow speed and the smaller pulley 12 at the quick speed; a
treadle lever 13 with a foot plate 14 is pivoted on a stud 15 and one end of

page_text: the lever 13 is turned up into a vertical position and slotted where it is con-
nected by a stud 51 to a cranked bracket 16 secured to a shaft 17 which has
its bearings in fixed brackets 18 and 19 and carries between the bearings a
weight 20. To the end of the shaft. beyond the bearing 19, is secured a cranked
bracket 21, connected by a stud 22 to a slotted bracket 23 in which the stud
rests. A screw 24 passes through the bracket 23 and through a slot in a pro-
jecting portion of a stationary bracket 25 and connects the bracket 23 to a
bar 26 fitted and free to be moved endwise in the bracket 25; to the bar 26 are
secured two forks 27 and 28 which take into annular grooves in the bosses of
the two pulleys 11 and 12 respectively.
A stop piece or catch 29 pivoted to a bracket at 30 is employed to lock the
treadle in an intermediate position when it is desired that the doffer cylinder 4
shall remain stationary.
The drawing represents the parts in the positions they occupy when the doffer
cylinder 4 is stationary, the catch 29 being moved from its normal position,
indicated by dotted lines in Fig. 2, and brought over the treadle lever 13 so as
to hold it and the weight 20 in the positions shown: as soon as the catch 29 is
moved clear of the treadle, the weight 20 causes the shaft 17 to move on its
axis and raise the foot plate 14 and simultaneously the stud 22 acting upon the
cranked bracket 23 moves it whereby the bar 26 is caused to traverse to the right
hand with the forks 27 and 28, and as these forks move, the pulleys 11 and 12,
which they control, are also moved, the clutch teeth on the latter, coming into
gear with similar teeth on the disc 50 fast on the boss of the pinion 9, and as
the pulley 12 is driven at the high speed the quickest speed is transmitted
through the pinion 9 and carrier wheels 8 and 7 to the doffer cylinder.
When it is desired to drive the doffer at the slow speed, the attendant places
his foot upon the foot plate 14 and presses it sufficiently to raise the weight 20
and thus slide the bar 26 far enough for the forks 27 and 28 to withdraw the
pulley 12 out of gear with the teeth on the disc 50 and bring the clutch teeth
on the slow speed pulley 11 into gear with the teeth on the other side of the
disc 50, and so through the pinion 9 and carrier wheels 8 and 7 transmit the
slow motion to the doffer cylinder and this speed will be maintained until the
operative removes his foot from the plate 14 when the weight 20 will turn the
shaft sufficiently to cause the bar 26 to be moved and bring the pulley 12 again
into gear with the disc 50 and so automatically change from the slow to the fast
speed.
The doffer cylinder can be stopped by depressing the foot plate far enough
and latching the catch 29 over it, as shown best in Fig. 2, when both the
pulleys 11 and 12 will be out of gear with the disc 50.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed we declare that what
we claim is:-
1. In a carding engine a weighted treadle lever combined with two pulleys and
a clutch for transmitting either of two speeds to or stopping the doffer, and
automatically changing the speed from the slow to the quick speed when the
treadle is released, substantially as herein described and as illustrated by the
accompanying drawings.
2. The general construction, combination and arrangement of parts constitut-
ing our improved mechanism designed to transmit two speeds to the doffer
cylinder of a carding engine and to automatically change the speed from the
slow to the quick speed when the treadle is released substantially as herein de-
scribed and as illustrated by the drawings.
