PROVISIONAL SPECIFICATION.
An Improved Method of Securing Card Clothing to the Flats of
Carding Engines.
1, ALFRED HITCHON of Globe Iron Works Accrington in the County of
Lancaster Machine Salesman do hereby declare the nature of this invention to be
as follows:-
This invention relates to a method of securing card clothing to the flat's of
carding engines by means of clips of the shape. and character described in the
Specifications of Letters Patent granted to me and numbered and dated respec-
tively 5844 of 1892, 22,194 of 1892, and 8471 of 1893. In the said Specifications
the clips are attached to the clothing and the flats are afterwards slid end wise upon
the said clothing and between the clips, the latter being subsequently closed on the
flats. It is an essential portion of the method described in the said Specifications
that the serrations formed in one edge of each of the said clips shall pass into the
clothing and..shall be bent outwards and:upwards so as to secure and stretch the
said clothing upon the flat. This operation and.the.final closing of the clips upon..
the flats.is as described in the.herein before named Specifications effected by means
of special mechanism....
It was possible.and.customary prior to the employment of clips approximately
of the character of those herein before referred to for the users of carding engines
to fix the card clothing to the flats on their own premises. The machinery which
bas. been hitherto employed with all forms of clips to close them upon the flats so
as to secure the clothing upon the same is of a costly nature and such as could not
be-profitably employed by the users of carding engines. When it is necessary to.
clothe the flats the latter have to be sent to the works of a machinist or card
clothing manufacturer thus entailing expense and loss of time to the user especially.
if the works of the latter are at some distance from the said, works. In order to
obviate the necessity of this procedure I have invented a mode of attaching the
clips and clothing to the flats by which the operation can be carried out on the
premises of the user.
In carrying my said invention into effect I place the card clothing upon a
suitable bed and drive into it the serrated edges of the two clips by which it is to
be attached to the flat in a manner analogous to that described in my Specification
22494 of 1892. I do this manually by means of a specially shaped tool preferably.
with a hollow curved face which is employed to strike repeatedly the upper edge
of the clip or clips until the serrations are sufficiently driven and curved in the
clothing. When the clips, are attached to the clothing I place the clothing with
its face downwards in a frame of sufficient length in which is formed a groove
prepared to receive it. The. clips rest upon two shoulders arranged within the
groove the teeth of the clothing being in the space between the shoulders.
I then slide the flat in end wise above the clothing and between the two clips. The
latter are then, bent over the flat which is held firmly in position by suitable
presser levers. By means of such specially shaped tool placed on one or both
clips and actuated by percussion either manually or otherwise I complete the
operation of clothing the flat, being thus enabled to attach the clothing firmly
without the employment of the costly machine hitherto necessary.

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 a method of securing card clothing to the flats of
carding engines by means of clips of the shape and character described in the
Specification of Letters Patent granted to me and numbered and dated respec-
tively 8471 of 1893. In the method described in the said Specification the clips
are attached to the clothing and the flats are afterwards slid end wise upon the said
clothing and between the clips, the latter being subsequently closed on the flats.
It is an essential portion of the method described in the said Specification that the
serrations formed in one edge of each of the said clips shall pass into the clothing
so as to secure the said clothing upon the flat. This operation and the final closing
of the clips upon the flats is as described in the hereinbefore named Specification
effected by means of special machines.
It was possible and customary prior to the employment of clips approximately
of the character of those herein before referred to for the users of carding engines
to fix the card clothing to the flats on their own premises. The machinery which
has been hitherto employed with all forms of clips to close them upon the flat so
as to secure the clothing upon the same is of a costly nature and such as could not
be profitably employed by the users of carding engines. When it is necessary to
clothe the flats the latter have to be sent to the works of a machinist or card
clothing manufacturer thus entailing expense and loss of time to the user especially
if the works of the latter are some distance from the said works. In order to
obviate the necessity of this procedure I have invented a method of attaching the
clips and clothing to the flats by which the operation can be carried out on the
premises of the user.
In order that my said invention and the method of carrying it into effect may
be easily understood I have hereunto appended a sheet of drawings wherein
Fig. 1 is a transverse section through one portion of my apparatus showing the
method of attaching the clips to the clothing:
Fig. 2 is a similar section through another portion of my apparatus which shows
the method by which the clip is finally closed on the flat and
Fig. 3 is a side view of one form of the tool I use to attach the clips to the
clothing.
In carrying my said invention into effect I place the card clothing A upon a suitable
bed B which is placed within the frame D having a loose plate E drawn towards
the bed B by the screws shown. I drive into the clothing A the serrated edges of
the clips FF by which it is to be attached to the card clothing manually by means
of a specially shaped tool C which may either be forked as shown in Fig. 2 or
single as in Fig. 3 and which is made with a hollow curved foot. The clothing is
placed with its face upward on the bed B the clips F F are placed with their
straight ends downwards and as in Fig. 2 the plate E is drawn up towards the
bed B so as to grip the clips slightly but sufficiently to hold them in their true
position. I then apply the tool to the upper edge of the clip or clips and strike
it repeatedly until the serrations are sufficiently driven and inserted in the clothing.
After the clips F F are attached to the clothing I place the clothing with its face
downwards in a frame G Fig. 2 also having a loose plate H drawn towards G by
the nuts shown. The frame is of sufficient length to receive the flat and is formed

page_text: with an opening prepared to receive the clothing and flat. The clips rest upon two
shoulders J J arranged at each side of the opening and the teeth of the clothing
are within the space between the shoulders. 1 then slide the flat L end wise above
the clothing and between the clips F F. The plate H is caused to grip the flat
and clips the flat being pressed on to the shoulders J J¹ prior to the nuts being
tightened by suitable presser levers K so that the flat rests firmly on the card
clothing over its whole area. After the flat and clips are gripped I close the clips
on to the flat L by means of a specially shaped tool M which is applied as shown
in Fig. 2 and subjected to repeated blows. I thus complete the operation of
clothing the flat by bending over the unattached edge of the clip and am enabled
to attach the clothing firmly at the mill without the employment of the costly
machine hitherto used.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
The improved means for attaching card clothing to the flats of carding engines
applied in the manner and for the purpose as herein described and illustrated.
Dated this 6th day of November.
