Improvements in Carding Engines for Carding Cotton, Wool, and
other Fibrous Materials.
I THOMAS KNOWLES of 287 Blackburn Road, Bolton in the county of Lancaster,
Cotton Spinner do hereby declare the nature of this invention to be as follows:-
My invention relates to carding-engines for carding cotton, wool and other fibrous
materials.

My invention consists firstly in arrangements by means of which I enable carding-
engines to be readily "driven at a slow speed in order that the "main cylinders
or "doffers or main cylinders" and " doffers" of such carding-engines may be
ground when necessary or desirable.
"
"
"
In carrying this part of my invention into effect I mount or form a toothed wheel
or pinion upon any suitable part of the "loose pulley" mounted upon the axle of the
"main cylinder" of each carding-engine to which this part of my invention is to be
applied and cause such toothed wheel or pinion to impart when desired, motion by
means of another toothed wheel or pinion or toothed wheels or pinions to a shaft or
equivalent part which shaft or equivalent part I cause to impart motion by means of a
toothed wheel or pinion or toothed wheels or pinions and other suitable means to.the..
fast pulley mounted upon the axle of the "main cylinder" of the carding-engine.
The shaft or equivalent part above mentioned I mount in a suitable plate or part
which I mount upon the axle of the "main cylinder" aforesaid or upon the boss of
the loose pulley upon the said axle or upon the boss of the fast pulley upon the said
axle or upon both of such pulleys. I so form the plate or part in which the shaft or
equivalent part above mentioned is mounted, that when the carding-engine is to be
driven at a slow speed such plate or part may be prevented from being rotated.
The said plate or part may conveniently be made in the form of a disc formed.
mounted and placed between the fast pulley" and the "loose pulley" in such
manner that while such disc may when required be prevented from rotating such disc
will not interfere with the passage from the "loose pulley" to the "fast pulley
and from the "fast pulley" to the "loose pulley" of the strap or belt by which the
carding-engine is driven..When the carding-engine is to be driven at a slow speed
in order that the main cylinder" or " doffer or main cylinder" and "doffer "
may be ground the plate or part in which is mounted the shaft or equivalent part
above mentioned is prevented from being rotated and the strap or belt by which the
carding-engine is "driven" or another strap or belt is placed upon the "loose pulley"
before referred to. Motion will then be imparted by the said "loose pulley" by
means of the toothed wheel or pinion or toothed wheels or pinion above mentioned
to the shaft or equivalent part above referred to and by such shaft or equivalent part
by means of the toothed wheel or pinion or toothed wheels or pinions above
mentioned to the "fast pulley "mounted upon the axle of the "main cylinder" or
to such axle and thus to the "main cylinder" and the other working parts of the
carding-engine. When it is desired to "drive" the carding-engine at the ordinary
speed the strap or belt employed to "drive" the carding-engine is placed upon the
fast pulley and the plate or part in which is mounted the shaft or equivalent part
above mentioned is allowed to rotate.
3
When the strap by means of which the carding-engine is driven is placed upon
the "loose pulley" in order that the carding-engine may be stopped the parts applied
to the carding-engine in accordance with this part of my invention are allowed to
rotate without causing any motion to be transmitted to the axle of the "main
cylinder."
When it is not desired to "drive" the carding-engine at a slow speed any part

page_text: or parts applied to the carding-engine in accordance with this part of my invention
may be removed therefrom or placed "out of gear" to be again replaced whenever
the use of such part or parts may be desired.
Although I have above referred to the "fast pulley" and "loose pulley" and the
plate or part by which the shaft or equivalent part aforesaid is carried as being
mounted upon or supported by the axle of the "main cylinder" such pulleys and
plate or part may be mounted upon or supported by a shaft separate from the axle
of the main cylinder" and arranged so as to be capable of transmitting motion to
the axle of the main cylinder."
<
A further part of my invention consists in means by which I am enabled to readily
restore the axles of the "main cylinders" of carding-engines to proper working
.position when from wear of such axles or the bearings in which they are mounted
or other cause such axles have ceased to be in proper working position.
According to this part of my invention I mount upon each end of the axle of the
"main cylinder" of each carding-engine to which this part of my invention is to be
applied or upon each of the pedestals in which such axle is mounted an excentric or
cam of suitable form which excentric or cam I cause to bear, by means of parts of its
circumference against brackets or parts which may be secured to or formed upon a
suitable part of the side-frame of the carding-engine which is adjacent to the said
excentric or cam or may be secured to or formed upon a part formed upon, secured
to or mounted upon the said side-frame. By the said excentric or cam being turned
by means of a handle or other suitable means the end of the axle of the
<< main
cylinder" upon which the said excentric or cam is mounted or the pedestal on which
the said excentric or cam is mounted may be moved in order that the said end of the
axle of the "main cylinder" of the carding-engine and the pedestal in which the
axle is mounted may be adjusted into position horizontally. After the said excentric
or cam has been moved into the required position it may be secured therein by
means of a set-screw or other suitable means in order that no further movement
of the pedestal in which the said end of the axle of the "main cylinder" is mounted
may take place. In order that if necessary the said end of the axle of the "main
cylinder" may be adjusted in position vertically a suitable wedge or suitable wedges
is or are provided and arranged to act in conjunction with another wedge or with an
inclined surface or inclined surfaces formed upon the side frame of the carding-engine.
The said wedge or wedges may be moved when required by means of a screw. or
screws or other suitable means. An excentric or cam such as is above described is
provided at each end of the axle of the "main cylinder" and if desired the excentric
or cam at one side of the carding-engine may be connected to the excentric or cam at
the other side of the carding-engine by any suitable means.

Improvements in Carding Engines for Carding Cotton, Wool, and
other Fibrous Materials.
I, THOMAS KNOWLES of 287 Blackburn Road, Bolton in the County of Lancaster,
Cotton Spinner, do hereby declare the nature of this invntion and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement:-
My invention relates to carding-engines for carding cotton, wool and other
fibrous materials. .

My invention consists firstly in arrangements by means of which I enable carding-
engines to be readily driven" at a slow speed in order that the "main cylinders

In carrying this part of my invention into effect I mount or form a toothed
wheel or pinion upon any suitable part of the "loose pulley" mounted upon the
axle of the "main cylinder" of each carding-engine to which this part of my
invention is to be applied and cause such toothed wheel or pinion to impart when
desired, motion by means of another toothed wheel or pinion or toothed wheels or
pinions to a shaft or equivalent part which shaft or equivalent part I cause to impart
motion by means of a toothed wheel or pinion or toothed wheels or pinions and other
suitable means to the fast" pulley mounted upon the axle of the main cylinder"
of the carding-engine. The shaft or equivalent part above mentioned I mount in a
suitable plate or part which I mount upon the axle of the "main cylinder" aforesaid
or upon the boss of the "loose" pulley upon the said axle or upon the boss of the
"fast" pulley upon the said axle or upon both of such pulleys. I so form the plate
or part in which the shaft or equivalent part above mentioned is mounted that when
the carding-engine is to be driven at a slow speed such plate or part may be
prevented from being rotated. The said plate or part may conveniently be made in the
form of a disc, formed and mounted and placed between the "fast pulley" and the
loose pulley" in such manner that while such disc may when required be prevented
from rotating, such disc will not interfere with the passage from the "loose pulley "
to the "fast pulley" and from the "fast pulley" to the "loose, pulley" of the strap
or belt by which the carding-engine is "driven." When the carding-engine is to be
driven at a slow speed in order that the "main cylinder" or "doffer" or "main
cylinder" and "doffer" may be ground the plate or part in which is mounted the shaft
'or equivalent part above mentioned is prevented from being rotated and the strap or
belt by which the carding-engine is "driven or another strap or belt is placed upon
the loose pulley" before referred to. Motion will then be imparted by the said
"loose pulley" by means of the toothed wheel or pinion or toothed wheels or pinions
above mentioned to the shaft or equivalent part above referred to and by such shaft
or equivalent part by means of the toothed wheel or pinion or toothed wheels or
pinions above mentioned to the "fast pulley" mounted upon the axle of the "main
cylinder or to such axle and thus to the main cylinder" and the other working
parts of the carding-engine. When it is desired to "drive" the carding-engine at
the ordinary speed the strap or belt employed to "drive" the carding-engine is placed
upon the "fast pulley "and the plate or part in which is mounted the shaft or
equivalent part above mentioned is allowed to rotate. When the strap by means of
which the carding-engine is "driven is placed upon the loose pulley in order that
the carding-engine may be stopped the parts applied to the carding-engine in
accordance with this part of my invention are allowed to rotate without causing any
motion to be transmitted to the axle of the "main cylinder." When it is not desired
to drive" the carding-engine at a slow speed any part or parts applied to the
carding-engine in accordance with this part of my invention may be removed there-
from or placed "out of gear to be again replaced whenever the use of such part or
parts may be desired.

Although I have above referred to the "fast pulley" and "loose pulley" and the
plate or part by which the shaft or equivalent part aforesaid is carried as being
mounted upon or supported by the axle of the "main cylinder" such pulleys and
plate or part may be mounted upon or supported by a shaft separate from the axle of
the "main cylinder" and arranged so as to be capable of transmitting motion to the
axle of the "main cylinder."
In the accompanying drawings Fig. 1 is a side view and Fig. 2 an end
elevation showing so much of a carding-engine as is requisite to illustrate this portion
of my invention. Fig. 3 is a side view partly in section and Fig. 4 an end elevation
also partly in section showing upon a larger scale a portion of that which is shown in
Figs. 1 and 2.

whole series of figures. is the axle of the carding-engine. Fast upon the axle a is
mounted the "fast pulley b and the "loose pulley" c. I mount or form a toothed
wheel or pinion d fast upon the "loose pulley c. Upon the bosses of the "fast

"
Fast upon the boss n is a pinion o which gears into a wheel p fast upon the boss
of the fast pulley b. Around the circumference of the plate or part e which is shown
as being in the form of a disc I form a groove e'. The plate or part e I form of such
diameter that it will not interfere with the passage from the "loose pulley" c to the
"fast pulley" b and from the "fast pulley" to the "loose pulley" c of the strap or belt
by which the carding-engine is driven." When the carding-engine is to be "driven "
at a slow speed in order that the "main cylinder" or "doffer" or main cylinder" and
"doffer" may be ground Iplace a rope or band g around the groove e' formed in the plate
or part e. The end q' of the rope or band g Iprovide with a hook through which is passed
the portion q of the rope or band q so that a loop of the rope or band q will encircle the
plate or part e. The end of the rope or band q I secure to a bolt r passing through
a bracket s secured to the side framing t of the carding-engine. Upon the bolt r are
formed screw threads upon which is mounted a winged nut u. When the strap
employed to drive the carding-engine or another strap is upon the "loose
pulley cand the loop of the rope or band q is by means of the nut u so drawn around
the plate or part e as to prevent the plate or part e from being rotated or from being
rotated as rapidly as the "loose "pulley c, the wheel will be rotated by means of
the pinion d and will by means of the axle f, pinion g wheel h, axle h¹. pinion j,
wheel k, axle k', pinion 1, wheel m, boss n, and pinion o cause the wheel p and with
it the axle a and the "main cylinder" A of the carding-engine to be rotated at a
slow speed and in a direction opposite to that in which the loose "pulley c is being
rotated. The speed at which the "cylinder" A is rotated in relation to the speed at
which the loose" puley is rotated may be varied by the relative diameters of the
pinions d. g. 1, land o, and the wheels f, h. k. m, and p, being altered. When the
rope or band q is removed and the strap by means of which the carding-engine is
driven" is placed upon the "loose pulley" c in order that the cardling-engine may
be stopped the plate or part cand the parts carried thereon are allowed to rotate
around the axle a and no rotary motion will be imparted to the axe a of the main
cylinder A.
"
Although I have above described the plate or part e as being prevented by means of
the rope or band q from being rotated it is obvious and I would have it understood
that other means may be employed to prevent the plate or part e from being rotated
at such times as the carding-engine is to be driven at a slow speed. When it is
not desired to "drive" the carding-engine at a slow speed any part or parts applied
to the carding-engine in accordance with this part of my invention may be removed
therefrom or placed "out of gear" to be again replaced when the use of such part
or parts may be desired.
Although I have above referred to the "fast pulley" and "loose pulley" c and
plate or part e as being mounted upon or supported by the axle a of the "main
cylinder A such pulleys b and c and plate or part e may be mounted upon or sup-
ported by a shaft separate from the axle of the main cylinder" and arranged so as
to be capable of transmitting rotary motion to the axle of the "main cylinder", of
the carding-engine.
A further part of my invention consists in means by which I am enabled to readily
restore the axles of the "main cylinders" of carding-engines to proper working
position when from wear of such axles or the bearings in which they are mounted
or other cause such axles have ceased to be in proper working position.
According to this part of my invention I mount upon each end of the axle of the

page_text: "main cylinder" of each carding-engine to which this part of my invention is to be
applied or upon each of the pedestals in which such axle is mounted an excentric or
cam of suitable form which excentric or cam cause to bear by means of parts of
its circumference against brackets or parts which may be secured to or formed upon
a suitable part of the side-frame of the carding-engine which is adjacent to the said
excentric or cam or may be secured to or formed upon a part formed upon, secured
to or mounted upon the said side-frame. By the said excentric or cam being turned
by means of a handle or other suitable means the end of the axle of the "main
cylinder upon which the said excentric or cam is mounted or the pedestal on which
the said excentric or cam is mounted may be moved in order that the said end of the
axle of the main cylinder of the carding-engine and the pedestal in which the
axle is mounted may be adjusted into position horizontally. After the said excentric
or cam has been moved into the required position it may be secured therein by
means of a set screw or other suitable means in order that no further movement of
the pedestal in which the said end of the axle of the "main cylinder" is mounted
may take place. In order that if necessary the said end of the axle of the "main
cylinder" may be adjusted in position vertically a suitable wedge or suitable wedges
is or are provided and arranged to act in conjunction with another wedge or with an
inclined surface or inclined surfaces formed upon the side-frame of the carding-
engine. The said wedge or wedges may be moved when required by means of a
screw or screws or other suitable means. An excentric or cam such as is abovedescribed
is provided at each end of the axle of the "main cylinder" and if desired the excentric
or cam at one side of the carding-engine may be connected to the excentric or cam
at the other side of the carding-engine, by any suitable means.
This portion of my invention is shown in Figs. 5 and 6 of the accompanying
drawings. Fig. 5 is a front elevation and Fig. 6 an end view partly in section
showing so much of a carding-engine as is requisite to illustrate this portion of my
invention. The same letters of reference are applied to corresponding parts in both of
the figures.
is the side frame of the carding-engine in which is formed a recess ¹. In the
recess place the pedestal w which supports so that it is free to be revolved therein
the axle of the "main-cylinder" of the carding-engine. Upon the pedestal w I
form a circular boss y the axis of which boss y is placed excentric to the axle x. Upon
the bossy and free to be turned thereon I mount an excentric or cam z which is
prevented from moving longitudinally upon the bossy by means of a collar y¹. Upon
or secured to the excentric or cam z is a handle 2. Passing through a slot formed
in the handle is a bolt 1 passing through a curved slot 2 formed in a bracket 3.
secured to the side frame of the carding-engine. The bolt 1 is provided with a
nut by means of which the handle 2' may be secured to the bracket 3.
circumference of the excentric or cam z abuts against the opposite sides of the
recess v¹.
The
Upon the lower surface of the recess ¹ I form or secure an inclined surface 4.
Upon the inclined surface 4 1 place a part 5 the lower surface of which I form as an
incline which rests upon and corresponds to the inclined surface 4. Upon the upper
surface of the part 5 I form a horizontal surface 5ª upon which rests the base of the
pedestal. To the part 5 is secured a rod 6 upon which are formed screw threads.
The rod 6 passes freely through a hole formed in a bracket 7 secured to the side-
frame v. At the sides of the bracket 7 are placed nuts 8. 9. having screw threads
which take into the screw threads formed upon the rod 6. When it is desired to
adjust the axle x to its correct working position the bolts 10 by which the pedestal w
is secured to the side-frame are slackened, the nut 1 being slackened and the
handle being turned in the direction indicated by the arrow B the pedestal we will
by means of the cam or excentric z be traversed along the horizontal surface 5* in
the direction indicated by the arrow C. By the handle Z' being turned in a
direction opposite to that indicated by the arrow B the pedestal we will be traversed
along the horizontal surface 5ª in a direction opposite to that indicated by the arrow C.
By the excentric or cam z being turned upon the boss y in the direction indicated by

page_text: the arrow B or in the opposite direction as may be required the axle x may be
adjusted in horizontal position. By the nut 9 being turned in a suitable direction.
the nut 8 having previously been turned so as to be removed from the bracket 7 the
part 5 will be moved in the direction indicated by the arrow Dand the inclined sur-
face of the part 5 being moved along the inclined surface 4 will cause the axle x to
be raised. By the nut 8 being turned in a suitable direction the nut 9 having pre-
viously been turned so as to be moved away from the bracket 7 the part 5 will be
moved in the direction opposite to that indicated by the arrow D. so that the axle æ
will be lowered. By the part 5 being moved longitudinally upon the inclined surface 4
the axle may be raised or lowered. By the excentric or cam z being turned so as
to move the pedestal w in a suitable direction and the part 5 being moved as may be
required the axle & may be adjusted into the position desired. After the axle has
been placed in the desired position the nuts 1, and 8 or 9 as may be the case, are
tightened and the pedestal w is by means of the bolts 10 firmly secured upon the
side framing e. Although I have only shown this part of my invention as applied at
one side of a carding-engine an apparatus similar to that above described in reference
to this part of my invention is applied to the opposite side of the carding-engine.
Although I have above described the boss y as being excentric to the axle x such
boss y may be made concentric with the axle a.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the sanic is to be performed I declare that what I
claim is:-
"

slow speed in order that the "main cylinder or doffer or main cylinder"
and "doffer may be ground when necessary or desirable, a plate of part such
as that hereinbefore described arranged between the "fast" pulley of the carding-
engine and the "loose" pulley thereof and carrying gearing so arranged that when
the said plate or part is prevented from rotating, the main cylinder may be "driven
at a slow speed by means of a strap or band placed upon and imparting motion to the
" loose " pulley.
