IMPROVEMENTS IN OARDING ENGINES
Year: 1886

page_text: I FREDERICK WILKINSON, of Hanover Mills, Reddish, in the County of Lancaster,
Yarn Agent do hereby declare the nature of said Invention for IMPROVEMENTS IN
OARDING ENGINES, to be as follows:-
My invention relates to improvements in carding engines, and the chief object of
my improvements is to reduce the wear on the ends of the revolving flats and also
to facilitate the adjustment of the clothing to the main cylinder.
In carrying my Invention into effect I dispense with the ordinary flexible bend
and I employ instead on each side of the machine a spider wheel or disc wheel
which is mounted preferably upon a flanged bush fitted on the shaft" of the main
cylinder, the flange of this bush is slotted and bolted to "the engine bend or fixed
part of the frame in such manner that the bush, and the wheel can be adjusted
concentrically with the periphery of the main cylinder; or the spider wheel could
be fitted directly on the shaft of the main cylinder or on a turned boss on the
bearings of the main cylinder.
'
.
A feature of my Invention is to give a slow revolving motion to the spider
wheel so that the surface speed of the wheel equals the speed at which the flats
travel and thus there is no friction between the flats and the wheel'consequently a
coating of any suitable material could be laid on the periphery of the wheel.
After the flats have been set to the clothing of the main cylinder it is neces-
sary to turn, grind, or otherwise reduce the diameter of the wheel whenever the
cylinder clothing is re-ground.

I FREDERICK WILKINSON, of Hanover Mills, Reddish, in the County of Lancaster,
Yarn Agent, do hereby declare the nature of said Invention for IMPROVEMENTS
IN CARDING ENGINES, 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 improvements in carding engines and the chief object of
my improvements is to reduce the wear on the ends of the revolving flats and also
to facilitate the adjustment of the clothing to the main cylinder.
In carrying my Invention into effect I dispense with the ordinary flexible bend
and I employ instead on each side of the machine a spider wheel or disc wheel which
is mounted preferably upon a flanged bush fitted on the shaft of the main cylinder;
the flange of this bush is slotted and bolted to the engine bend or fixed part of the
frame in such manner that the bush and the wheel can be adjusted concentrically
with the periphery of the main cylinder; or the spider wheel could be fitted on a
turned boss on the bearings of the main cylinder.
A feature of my Invention is to give a slow revolving motion to the spider
wheel so that the surface speed of the wheel equals the speed at which the flats
travel and thus there is no friction between the flats and the wheel consequently a
coating of any suitable material could be laid on the periphery of the wheel.
After the flats have been set to the clothing of the main cylinder it is necessary
to turn grind or otherwise reduce the diameter of the wheel whenever the cylinder
clothing is re-ground.
And in order that. my Invention may be fully understood and readily carried
into effect I will describe the accompanying Sheet of Drawings, reference being
had to the figures and letters marked thereon.
Figure 1 is a side elevation of a carding engine to which my Improvements have
been applied and Fig. 2 is a transverse vertical section of the same.
In these views-a is the main cylinder and b the cylinder shaft supported in a
bearing in the block or pedestal o; d is the engine bend; d the lower framing
and e the flats; f is the wheel in this case a spider wheel which I employ
according to my Invention fitted and free to revolve upon a flanged bush g
secured by bolts g¹ to the pedestal c. On the periphery of the wheel f I propose
to secure a ring of metal for a layer or coating of any suitable material on which
the ends of the flats bear. The spider wheel fis, provided with worm teeth f³ on
its face and is caused to revolve at the same or approximately the same surface
speed as the speed at which the flats travel by means of a worm shaft h which
gears into the teeth and, is driven from any convenient part of the machine.
When the card clothing on the main cylinder a has been ground it is necessary
to reduce the diameter of the spider wheel fin order to adjust the flats. This may
be effected in various ways but preferably by grinding the ring f¹ on the periphery
of the wheel by means of a revolving grinding roller or cutter i held in an
adjustable bracket ; secured to the bend d. When however instead of the metal
ring the periphery of the wheel is covered or coated with other material such
as paper the diameter of the wheel might be reduced by cutting and trimming or
otherwise removing one or more layers of such material.

page_text: When the bearings of the shaft b wear the periphery of the wheel of may be
adjusted concentrically with the periphery of the main cylinder by slackening the
bolts g¹ and regulating the position of the bush.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what.
I claim is
1. In a revolving flat carding engine dispensing with the ordinary flexible
bends on which the flate travel and substituting therefor on each side of the engine
a wheel which is mounted adjustably and is caused to revolve at a surface speed
equal to or approximating the speed at which the flats travel.
2. In a carding engine, the combination with the revolving flats, of the wheel f
mounted on the adjustable flanged bush g or otherwise suitably mounted and
driven by worm gearing or otherwise at a surface speed equal to or approximating
the speed at which the flats travel substantially as herein shown and described.
3. The combination with the revolving wheel f of the ring of metal or other
suitable material f¹ substantially as herein set forth for the purpose specified.
