PROVISIONAL SPECIFICATION.
Improvement in the Setting Arrangement of Flexible Bends for
Revolving Flat Carding Engines.
CHARLES WHITWORTH of Star Iron Works, Heywood, Manager and ARTHUR
SMITH MILLS of Bolton Cop Tube Works, Bolton, Cop Tube Maker, do hereby
declare the nature of this invention to be as follows:-
This improvement relates more particularly to carding engines in connection
with which are used segments of cone shaped rings (generally known as flexible
bends) over which slide the working flats: we will explain our invention by
reference to the sheet of drawings filed with Specification No. 1029. A.D. 1881
granted to Frederick Mills, wherein Fig. 1 represents a section of the bend &
cylinder, a, b, b, c, & d, representing the bend & cone shaped rings, Fig. 2
represents a section of side elevation of bend, c,/, g, representing cone setting
screw & bracket. In our improvement we dispense with brackets g.
In our
improvement in place of setting screw f we employ setting screws or screwed studs
portions of which setting screws, screw into the bend a, b, b¹ & portions into the
cone c.
The setting screw may be screwed a certain distance one hand of thread & the
remaining distance the other hand of thread or we may employ a setting screw
screwed the whole length with one hand of thread but one portion to have a coarser
pitch of thread than the other portion.
The bend a, b, b', may have full places cast on to receive & give more bearing
to the setting screws, the cone c being recessed out to correspond with the full
places on the bend a, b, b.
By our arrangement to withdraw the cone c from the bend a, b, b', & thereby
lowering the cone d Fig. 1, if a setting screw with a left & a right hand thread is
employed on being turned so as to withdraw the cone c from the bend a, b, b', the
portions of the setting screw screwed into the bend a, b, b₁, & the cone c'will
respectively withdraw themselves from the bend a, b, b, & the coue c thereby
forcing the cone c from the face of the bend a, b, 61, if a setting screw is employed
the whole length of which is screwed with one hand of thread but with different
pitches of thread, supposing the portion with the finer pitch of thread is screwed
into the bend a, b, b', & the coarser portion into the cone c, on turning the setting
screw so as to withdraw the cone c, the setting screw will still further screw into
the bend a, b, b', but not in the same proportion that the cone c is withdrawn along
the coarser portion of the setting screw.
We employ suitable lock nuts. We do not employ setting or adjusting nuts.

CHARLES WHITWORTH of Star Iron Works Heywood, Manager and ARTHUR
SMITH MILLS of Bolton Cop Tube Works, Bolton, Cop Tube Maker, 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 improvements hereinafter described relate to that class of carding engine in
connection with which are used segments of cone shaped rings, (generally known
as flexible bends) over which slide the working flats.
The nature of the said invention and the manner in which the same has to be
performed or carried into practical effect will be readily understood on referring to
the sheet of drawings forming part of this Specification in which :-
Fig. 1. represents a section of the bend & cylinder, a. b. representing the bend,
c the bottom cone, d the top or flexible cone, the setting.screw & G the lock nut.
Fig. 2. is a partial side elevation of Fig. 1.
Fig. 3. represents on an enlarged scale a setting screw with right & left hand
threads as shown in Fig. 1, one portion of the setting screw f being screwed into
the bend a. b. b & one portion into the cone.c, to raise the flexible coue d the
lock nut G is loosened, & the setting screw is turned in such a direction that the
cone is drawn closer to the bend a. b. b', by reversing the direction in which
the setting screw is turned, the cone c will be forced from the face of the
bend a. b. b, thereby lowering the flexible cone d.
Fig. 4. represents on an enlarged scale a setting screw f1, with one hand of
thread, one portion of the setting screw being screwed with a coarser pitch of
thread than the other portion, the setting screw is adjusted similar to setting
screw f. Fig. 1.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The setting screw f, Fig. 3 with right & left handed threads, adjustable in
cone c and bend a. b..b¹.
2. The setting screw f¹ Fig. 4. with one hand of thread, one portion of the
setting screw having a coarser pitch of thread than the other portion, and adjustable
in cone c, & bend a. b. b.
