PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Adjusting the Flexible Rings or
Bends of Revolving Flat Carding Engines.
I, ALFRED HITCHON of Globe Iron Works Accrington Machine Salesman do
hereby declare the nature of this invention to be as follows:-
This improvement relates more particularly, to the class of carding engines
wherein are used segments of cone-shaped rings (which are generally known as
flexible bends) over which slide the revolving flats of carding engines: I will
explain my invention by reference to the 3 sheets of drawings filed with the
Specification of Letters Patent granted to Edmund Tweedale, No. 11514, A.D. 1885,
wherein Fig. 1. Sheet 1. at 2 and 3 are shown the flexible bends and cone-shaped
rings already refered to.-8 is section of card side,--1 card flat,-11 part of card
cylinder. I purpose in this my invention to dispence with the application of such
parts as stud bolts 7. being fixed at 4, 5, and 6. to the cone-shaped segment 3.
I dispence with such brackets as 13, and the adjusting nuts of studs 7 being no
longer necessary to take their fixings from same, as brackets 13 are entirely dis-
penced with.
By my application I fix similar studs as 7, stationary in the card side 8.
I bore the bolt holes at 4 entirely through the cone-shaped segment ring, and
slide the same on the stationary bolts, with which I compress the segment ring
towards the card side by adjusting nuts, to which I prefer to use an outside nut on
each bolt that I may have a fixed or adjustable dial plate to each nut, so as to read
each nut's settings, to show the distance of compression or withdrawal of the
segment ring 3. to or from the card side 8.
I also make provision for the withdrawal by backing nuts to each bolt at the
inside of ring 3, which may have teeth cut on their periphery, so that they may be
actuated by a key having a small pinion-wheel shaped end, being pushed through
holes bored through the segment ring 3. near to each wheel nut.
As a modification for withdrawing the segment ring 3, in lieu of the wheel nuts
aforesaid I may make use of a recessed bracket fixed to ring 3. so that the said
backing nut may be got to by a more ordinary kind of key from the outside.
I also may make use of adjusting nuts having a collar to withdraw the segment
rings aforesaid and lock nuts to secure such screw threaded collars in position
which are also provided with adjustable index to read a true setting position.
In all my modifications I make use of stationary studs or bolts and slide such
cone shaped segment rings on same.
Dated 4th August 1891.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Adjusting the Flexible Rings or
Bends of Revolving Flat Carding Engines.
ALFRED HITCHON Globe Iron Works Accrington Machine Salesman. I 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 the class of carding engines,
wherein are used segments of cone shaped rings (which are generally known as
bends) over which slide the revolving flats of carding engines.

page_text: The nature of my 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 sheets of drawings forming a part of this Specification in which
Fig. 1. Sheet 1. is a sectional elevation of part of carding engine, card flat, and
adjustable apparatus, whereby the bends and flats are set or adjusted.
Fig. 2 on same sheet is shown on a drawing to an enlarged scale, stud bolt &
adjusting nuts as screwed and pinned into card side 8 Fig. 1. through its collar 5,
by pin 6.
Figs. 3 are plan elevation & section of outside adjusting nut adjusting dial
secured by a nick headed set screw shown. Fig. 3 section illustrates the mounting
of the figured index-dial 13", on adjusting nut 12, shewing how this dial may be
separately adjusted and secured by the nick headed set screw, as aforesaid, so as to
better enable all the index dials being set or adjusted to read in unison. Fig. 1
illustrates the parts of Figs. 2 & 3 set in their position for raising or lowering
flexible ring 2 by the outside adjusting nuts 12 in combination with locking or
backing wheel nuts 9 for securing same in position as may be required, 9ª being
set towards or from 10" by turning these nuts in one direction or the other. On
Sheet 2, Fig. 1 is a front elevation of upper part of card side illustrating the
position of five adjusting nuts to segment ring at one of these studs is shewn
(dotted) one of the inside nut wheels, to better illustrate the position of the teeth
of same as coming part way in the lesser circular bored holes which are shewn near
to each adjusting nut. Fig. 2 shews one of these nuts set edge way with a pinion
wrench in contact with same (drawn to enlarged scale) the half circular end of
this wrench may be used to outside adjusting nuts and the pinion end inserted
through the holes near to the tooth wheel nuts behind the segment ring. A portion
of a plan section of this application is illustrated on Sheet 3, Fig. 6. All figures
on this sheet are marked in keeping with their references to same like parts as
figures on Sheet 1 as they are only slight modifications of the application of the
manner in which the adjusting or back locking nuts as they may be applied to
fixed stud 7. Fig. 3, Sheet 3, illustrates a spiral spring in lieu of a lock nut,
as a modification to keep the cone shaped segment pressed against the outside
adjusting nut.
Figs. 4 & 5 illustrate adjusting nuts mounted in connection with screwed bushes
for backing and securing the cone segment rings, as modifications of this invention
as applied to the stationary screwed studs for the purpose as set forth.
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 :-
The stationary stud bolts 7, being fixed in the upper card sides 8, over which
slides the cone segment ring 3, the latter being adjustable to position by such
nuts (with and without adjustable dial plates) as herein fully described & illus-
trated by drawings annexed, which form part of this Specification.
Dated this Fifth day of August 1891.
