Improved Construction, Combination,.and Arrangement of Driving
Apparatus for Speeding the Cylinder and Doffer of Carding
Engines when Grinding the Cards: thereon:
We EDMUND TWEEDALK Manager; SAMUEL TWEEDALE; Manager and CHARLES
MILLS Manager, all of Globe Works, Accrington, in the County of Lancaster. do hereby
declare the nature of this invention to be as follows:-
-
The invention aforesaid is designed for giving a slow motion to the main cylinder,
and doffer of Carding engines during the process of grinding the cards.
In carrying out our invention we connect or cast together the ordinary main
driving pulley and the pulley that drives the licker-in, by means of a boss, and wo
use such boss as a slow motion pulley for driving the doffer through the ordinary
doffer gearing-for the purpose of grinding.
The above mentioned pulleys are hereafter referred to as the "combined pulleys."
When the slow motion required we loose the set screws of bolts that fasten the
combined pulleys to the main cylinder shaft. A collar or flange is fixed on one side
of the combined pulleys to prevent endwise movement, the loose pulley answering the
same purpose on the opposite side. The above flange or collar is used as a means of
fastening the combined pulleys to the main cylinder shaft: or they can be fastened by
means of set screws, through the boss of the said pulleys. When the combined'
pulleys are disconnected or allowed to turn loosely on the main cylinder shaft, the
driving belt is put on as usual for grinding but by reason of the combined pulleys.
being loose on the shaft no motion is given to the main cylinder until the belt is
placed on the small part of the combined pulleys and the doffer pulley. This gives
motion through the gearing to the doffer and from the doffer to the cylinder by
another belt. That part of the combined pulleys that usually drive the licker in is
used for driving the emery rollers. If desirable the boss of the combined' pulleys can
be placed on the outside of the licker in pulley but in this case the pulley on the
licker in would have to be used as a carrier pulley and the d'offer would be driven by
the ordinary belt. from.the licker.in..

We, EDMUND TWEEDALE, Manager SAMUEL TWEEDALE, Manager, and CHARLES
MILLS, Manager, all of Globe Works, Accrington, in the County of Lancaster, 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:-
The invention aforesaid is designed for giving a slow motion to the main cylinder,
and doffer of carding engines during the process of grinding the cards.
In carrying out our invention we connect, or cast together the ordinary main
driving pulley, and the pulley that drives the "licker in" by means of a boss, and we
use such boss as a slow motion pulley for driving the doffer through the ordinary
doffer gearing for the purpose of grinding.
The above mentioned pulleys are hereafter referred to as the "combined pulleys."
When the slow motion is required we loose the set screws of bolts that fasten the
combined pulleys to the main cylinder shaft, a collar or flange fixed on one side of
the combined pulleys to prevent endwise movement the loose pulley answering the
same purpose on the opposite side. The above flange or collar is used as a means
of fastening the combined pulleys to the main cylinder shaft, or they can be fastened
by means of set screws through the boss of the said pulley's. When the combined
pulleys are disconnected or allowed to turn loosely on the main cylinder shaft, the
driving belt is put on as usual for grinding, but by reason of the combined pulleys
being loose on the shaft no motion is given to the main cylinder until the belt is
placed on the small part of the combined pulleys and the doffer pulley. This gives
motion through the gearing to the doffer and from the doffer to the cylinder by
another belt. That part of the combined pulleys that usually drive the "licker in."
used for driving the emery rollers-If desireable the boss of the combined pulleys can
be placed on the outside of the "licker in pulley, but in this case the pulley on the
licker in would have to be used as a carrier pulley, and the doffer would be driven by
the ordinary belt from the licker in."
Such being the nature, and object of our said invention; the following is a complete
description of same reference being had to the accompanying drawings forming a part
of this specification, in which
Fig. 1. is an end elevation of cylinder and doffer having our improvements applied
thereto.

page_text: At 1 is the axis of the cylinder 2 on which axis is the main driving pulley 3 cast by
the connecting boss 4 to the pulley 5 the latter drives the "licker in 5 during the
ordinary working of the machine.
On the shaft 1 is fastened the boss or collar 6 by set screw 7.
During the ordinary working of the machine the bolts 8, 9, are at positions A. B.
(see Fig. 4) wherby they bolt the boss or collar 6 fast to the combined pulleys 3. 5.
so that the driving strap on the pulley 3 drives the machine at its ordinary working
speed.
In order to obtain the requisite decrease of speed of rotation of the doffer 10 and
cylinder 2. for grinding the cards thereon, the bolts 8, 9, are slacked and moved in
the slots a, b, (see Fig. 3) to the positions C. D. and clear of the collar 6 whereon the
combined pulley 3, 5, is loose on the shaft 1. The connecting boss 4 is now available,
and utilized as a pulley for slowly driving the doffer 10 by means of the strap 11,
pulley 12 and gear 13, 14.
The slow motion of the doffer so obtained is utilized for imparting a slow motion
to the main cylinder 2 through the pulley 15 strap 16, and pulley 17, on axis of
cylinder 2. The grinding roller 18 for grinding the cards on the cylinder 2, is driven
by the strap 19 from the pulley 5. the grinding roller 18 for grinding the cards on
the doffer 10 is driven by the strap 19 from pulley 20 on axis of roller 18 (see plan
view Fig. 2.) the cards on cylinder, and on doffer being ground simultaneously. It
will be understood that during the grinding the cards, the "licker in" 5 is not in
operation, hence the pulley 5 is available for driving the roller 18, as described.
Having now particularly described and ascertained the nature and object of our
said invention, and in what manner the same is to be employed, we declare that what
we claim is :-
1. The parts 3. 4. 5. constituting the improved "combined pulleys
" and the
attaching and detaching part 6, all in combination, and substantially as herein fully
described and illustrated in the annexed drawings.
"
2. The combined pulleys" and part 6 herein described in combination with, and
for operating the doffer and cylinder jointly, or the doffer separately, as, and for
purpose herein fully described, and substantially as illustrated by annexed drawings.
3. The combination pulleys 3. 5. for operating, and in combination with the
grinding rollers 18, 18, as described and substantially as illustrated by annexed
drawings.
