PROVISIONAL SPECIFICATION.
Improvements in Carding Engines.
ALFRED HITCHON Globe Iron Works Accrington Machine Salesman. I do
hereby declare the nature of this invention to be as follows:-
This improvement relates to the mounting of carding engine flats which are
usually coupled together by an endless chain at each end of the flat, each flat being
secured in position by a set screw stud being passed through the links of the chain,
which stud requires to be taken out completely at any time when it is necessary for
the flats to be removed from the chain for grinding or other like purposes.
In this my invention I make & fix such stud pins in the flats that the chains can
be slided over their outer ends in such a manner that the flats can be removed from
the chains without the trouble of the studs being unscrewed or withdrawn from the
flats thereby preventing their threads from being worn or damaged by such repeated
operations and being also less liable to come loose.
For the convenience of keeping the chain in proper position to the flat I make
use of outside guides or for every certain quantity of flats that have my improved
stud applied an ordinary stud headed bolt may be made use of but only in such
quantities as may be found requisite for keeping the chain from getting too far out
of line in its working as it travels along with the flats.

COMPLETE SPECIFICATION.
Improvements in Carding Engines.
I, ALFRED HITCHON of Globe Iron Works Accrington, in the County of
Lancaster, Machine Salesman, 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 relates to improvements in the mounting of carding engiue flats,
which are usually coupled together by an endless chain at each end of the flats,
each flat being secured in position by a set screw stud being passed through the
links of the chain. When it is necessary for the flats to be removed from the chain
for grinding or other purpose each set screw stud in each and every flat has to be
taken out and this entails great loss of time, and wear, and tear of the set screw
studs.
According to this invention I make and fix said stud pins in the flats that the
chains can be slided, or drawn off over their outer ends so that the chains are
removed from the flats without the necessity of unscrewing the stud pins. In order
to prevent the chains getting out of line or out of position, I employ, say to every
twelfth flat, an ordinary stud headed bolt, the intervening flats being held in the
chain by means of the stud pins as aforesaid.
Such being the nature and object of the said invention the following is a
complete description of same, reference being made to the accompanying drawings
in which :-
Fig. 1 is a view of a part of a carding engine, the flats being shewn connected to
the chain in the improved manner.
Fig. 2 is a view of one of the stud pins.
According to this invention the flats 1. 1 are attached to the endless chains 2 on

page_text: each side of the carding engine, by means of the stud pins 3, said stud pins having
long cylindrical heads (see Fig. 2). When the screwed portions of the stud pins 3
are inserted into the ends of the flats 1. 1 the long cylindrical heads will protrude,
or extend from the ends of the said flats 1. and the cylindrical heads are
received in corresponding holes 4 in the chains 2 on each side of the carding
engine.
The chains 2 are of the ordinary construction for such purposes, and in order to
prevent the chains moving apart and so releasing the flats 1. 1 I employ at intervals
of say every twelfth, thirteenth or fourteenth flat an ordinary stud headed bolt 5
which keeps the chains in correct position in relation to the flats.
When it is desired to remove the flats from the engine, and chains 2. 2 it is only
necessary that the stud headed bolts 5 should be unscrewed and removed whereon
all of the flats can be withdrawn by sliding the chains off the ends of the cylindrical
heads of the stud pins.
By mounting the flats in the manner herein described a great saving in time is
effected both on inserting the flats in the engine, or when withdrawing same for
grinding or other purpose; the many disadvantages of the studs, or pins working
loose, or becoming worn by repeated screwing, and unscrewing is obviated.
Having now particularly described and ascertained the nature and object of the
said invention, and in what manner the same is to be performed, I declare that
what I claim is :-
The improvements in carding engines comprising the employment of stud pins
such as 3 applied to the flats and chains of said engines for purpose set forth, and
as herein fully described.
