Improvements in Carding Engines.
We, EDMUND TWEEDALE, SAMUEL TWEEDALE and JOSEPH SMALLEY, of
Castleton, near Manchester, in the County of Lancaster, Machine Makers, do
hereby declare the nature of this invention to be as follows:-
This invention consists of an improved arrangement of parts and method of
setting or regulating the flexible bends on which the flats work in carding engines.
In carrying out our invention we insert five or any other convenient number of
regulating screws in that part of the bend or frame-work of the carding engine
made for the reception of the flexible bend.
The ends of these screws are set to the requisite curve of the cylinder and
support the bottom edge of the flexible bend, the sides resting against the frame-
work of the carding engine. To force the flexible bend to follow the curve the
regulating screws are set to, we place a screw bolt opposite each regulating screw.
These bolts rest on an inclined surface formed on one side of the flexible bend.
the bolts being tightened they lock the flexible bend tightly on the ends of the
regulating screws and against the sides of the bend or frame-work of the carding
engine.
On
The regulating screws are provided with the usual dial to shew the amount of
adjustment.

We, EDMUND TWEEDALE, SAMUEL TWEEDALE, and JOSEPH SMALLEY of
Castleton, near Manchester, in the County of Lancaster, Machine Makers, 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 consists of an improved arrangement of parts and method of
setting or regulating the flexible bends on which the flats work in carding engines.
In carrying out our invention we insert five or any other convenient number of
regulating screws in that part of the bend and framework of the carding engine
made for the reception of the flexible bend. The head ends of these screws are
formed to the requisite curve of the cylinder, and support the flexible bend, the sides
of the latter resting against the framework of the carding engine. To force the
flexible bend to follow the curve to which the heads of the regulating screws are
The heads of these
set to, we place a screw bolt opposite each regulating screw.
screw bolts bear upon an inclined surface formed on one side of the flexible bend.

page_text: On the screw bolts being tightened, they lock the flexible bend tightly on the
head ends of the regulating screws, and against the side of the bend or framework
of the carding engine.
The regulating screws are provided with the usual dial to shew the amount of
adjustment.
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,
in which:-
Fig. 1 is general elevation of frame and bend.
Fig. 2 is a vertical section shewing flexible bend, framework, adjusting screw,
and screw bolt.
Fig. 3 is a front elevation of Fig. 2.
Fig. 4 is a part shewn detached.
At 1. 1. 1 is the framework which carries the flexible bend 2, the latter fitting
between the surfaces a, d of the recessed framework 1.
The under surface e of the flexible bend 2 rests upon the curved head 3 of the
adjusting screw 4, and on which screw is the dial nut 5. The chased end of the
adjusting screw 4 is received in the hole 6 formed in the framing 1.
At 7 is a screw bolt, its lower and chased end being received in a tapped hole
formed in the forked nut 10, the forked portion clips the bolt 4, and so the nut is
prevented turning round on the screw 7.
To effect any required adjustment of the flexible bend 2, for example say to raise
the bend 2. slacken the screw bolt 7, then by turning the dial nut 5, the bolt 4 will
be raised, its curved head 3 lifting the bend 2 until sufficiently raised, whereon
the screw bolt 7 will be tightened, and its head 8 will press the bend 2 firmly down
upon the curved head of the bolt 4, and against the face d of the frame 1, thus the
bend is firmly held on the head of said bolt 3, and secured and confined between the
parts a and d of the framing. 1.
Turning the dial nut in the opposite direction will lower the adjusting screw 4,
and the screw 8, when turned, will force the bend 2 to follow, and secure the bend 2
on the head 3 and against the face d as described.
The dial nut 5 bears on the face of the boss k.
That part of the framing marked 1* is not indespensable, but we prefer to
use it as shewn, as such part screens the heads 3 and upper part of the adjusting
screws 4.
In the foregoing, reference is made for convenience in description to one adjusting
screw 4, one bolt 7, and one dial nut 5, but such appliances are employed at
intervals of distance, as will be seen on reference to Fig. 1 of the drawings.
Having now particularly described and ascertained the nature and object of our
said invention, and in what manner the same is to be performed, we declare that
what we claim is :-
The improvements in carding engines wherein is comprised and combined a
flexible bend fitting within a recessed framework of a carding engine, together with
the raising and lowering screws, and the locking bolts for adjusting and fixing said
bend in position, and as herein described and illustrated by the drawings annexed
hereto.
