We GEORGE ASHWORTH and ELIJAH ASHWORTH of the firm of Ashworth Brothers
of the Moss Brook Works, Collyhurst, Manchester, in the County of Lancaster,
Engineers, do hereby declare the nature of this Invention to be as follows:-
The
Our Invention relates to the flats used in Carding Engines employed in the carding
of cotton and other fibrous materials and to former Inventions relating to the
attachment of the clothing to the bars and particularly to the Invention for which
Letters Patent No. 2011 of the year 1888 have been granted to us. In the specifica-
tion of the said invention we described the use of sheet metal clips which enclosed the
edges of the clothing and the bar and tightly gripped the fabric and the bar. In our
present invention we use sheet metal clips which are secured to the faces of the bars
and have their edges turned over upon the foundation fabric so as to grip the same
the edges of the bar not being enclosed or concealed as in our former invention.
strip of clothing is either secured by means of one piece of sheet metal or of two
pieces. In the first case we take a riband of sheet steel or of other suitable sheet metal
a suitable degree wider than the bar and secure it to the face of the bar the edges
being turned up either before or after the attachment to the bar. The edges of the
sheet metal are turned and pressed down upon the foundation fabric so as to grip the
same as in our said former invention. If preferred the sheet metal may extend over
the back of the bar from edge to edge instead of over the face of the bar. When
using two ribands of sheet metal such ribands may be wide enough to meet below the
clothing fabric or be of a width suitable to enable the ribands to be secured to the
bar. In the latter case the bar may or may not be rebated to receive the clip so
that a level seating for the clothing is produced. The inner edge of the rebate might
be beveled or undercut and one edge of the clip be shaped to correspond in order to
render the attachment more secure. The clip piece or pieces may be attached to the
bar by means of rivets pins screws or other fastenings or by soldering or by suitable
means. We might tin or prepare the bar or the face of the same so as to facilitato
the soldering of the clips to the bar the clip being made of tinned sheet steel or metal
or of untinned metal as preferred. In some cases legs or projecting parts of the clip
might pass through holes or slits in the bar and be clenched at the back of the same
or extend over the edge of the bar and be clamped upon the back of the bar or be
clamped upon a rib or bead or be turned down within a groove or upon a beveled
surface. In some such cases the part which would be turned down upon the fabric
would be continuous and in others would consist of a number of fingers or parts.
Each clip may extend from end to end of the card clothing or be in two or more parts
arranged either in close contiguity or separated by spaces.

Improvements in the Method of and Means for Attaching the
Clothing to Carding Engine Flats.
We GEORGE ASHWORTH and ELIJAH ASHWORTH of the firm of Ashworth Brothers
of the Moss Brook Works, Collyhurst, Manchester, in the County of Lancaster,
Engineers, 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 and accompanying drawings :-
Our Invention relates to the flats used in Carding Engines employed in the carding
IP 71

page_text: of cotton and other fibrous materials and to former Inventions relating to the attach-
ment of the clothing to the bars and particularly to the Invention for which Letters
Patent No. 2011 of the year 1888 have been granted to us. In the specification of
the said invention we described the use of sheet metal clips which enclosed the edges
of the clothing and the bar and tightly gripped the fabric and the bar. In our
present invention we use sheet metal clips which are secured to the bars independently
of the foundation fabric.
In order that the nature of our Invention and the manner in which we propose to
carry the same into effect may be clearly understood we will describe our invention
with reference to the accompanying drawings wherein are illustrated several modifica-
tions in the method of attachment of the sheet metal clips to the flat bar. In all the
Figs. the flat bar is represented in section by a. In Fig. 1 is a double clip made
from a riband or strip of sheet metal of a suitable nature but preferably of sheet steel
cut or made wider than the face of the bar to the extent necessary to enable the two
edges to be turned over as at b. This turning or bending over of the edges may be
effected either before or after the attachment of the clip to the bar. The attachment
to the bar may be effected in any suitable manner. In the example the clip is secured
to the bar by means of rivets c c but if preferred screws or bolts might be used or the
attachment might be effected by some of the methods hereinafter described. To
avoid projection of the rivet heads or ends above the general surface the holes are
countersunk and the margin of the hole in the clip is supposed to have been pressed
into the countersunk hole in the flat either by the pressure of the rivet or of a conical
tool or punch or punch and die but this detail may be varied or departed from as
preferred or considered to be most suitable. In place of using rivets or similar
fastenings we may solder the clip to the bar. In such a case we should prefer to tin
or electro-plate with tin the whole of the bar or the face of the bar in order to
facilitate the soldering of the clip piece to the bar. It would also be convenient to
make the clip piece of tinned, sheet metal. We may combine the two methods the
clip piece being first secured by means of rivets screws or fastenings and then soldered
or sweated to the bar. In such a case fewer rivets or fastenings would be required
than if the security depended solely upon such fastenings. We are aware that the
clip piece might be brazed to the bar but we do not consider such a method of attachi-
ment would be practically convenient and suitable. The clip piece having been
attached to the bar the strip of card clothing is placed in position with its edges below
the clips 6 and the latter are rolled pressed or closed down upon the margins of the
clothing so as to securely grip and hold the same as in our said former Invention the
means therein set forth or suitable means being employed to stretch the clothing or to
ensure its being evenly secured to the bar. In Fig. 2 the clip on one side of the bar
is represented as having been so closed down. In Fig. 3 the clip piece bextends
over the back of the bar from edge to edge instead of over the face of the bar.
In
such a case it might not be necessary to use solder or rivets or other fastenings to
attach the clip piece to the bar but we have shown how it might be secured by means
of rivets indicated by c. If preferred solder might be used either alone or as an
adjunct to the screws or other fastenings. In Fig. 4 two separate clips d d are
attached to the bar each clip being made from a strip of metal half the width of the
strip which would be required for the double clip c and each strip being turned over
at one edge only. The two clips are applied to the bar in the positions shown in the
drawing their straight edges meeting together at e. In Fig. 5 the clips are represented
as being made from narrower strips of metal so that they do not meet together as in
Fig. 4. The face of the bar is rebated so that the surfaces of the clips upon which
the backs of the clothing will rest are about flush with the face of the bar. The side
of the rebate may be undercut as at for be cut as at f¹. If it is not considered to be
necessary or advisable to rebate the face of the bar such rebating might be dispensed
with but we should prefer to fill up the space between the opposed edges of the clips
so as to obtain a flat surface across the bar. For this purpose a suitable cement or a
filling up strip might be used. The clips may be attached, by the means mentioned
when describing Fig. 1 or by means of projecting legs or parts as hereinafter

page_text: described. In Fig. 6 the clip is adapted to be attached to the edge of the bar by
means of screws or of pins or rivets driven tightly into holes drilled in the bar or by
means of solder or of such screws pins or rivets and solder. In Figs. 7 and Sa
groove or saw cut to receive one edge of the clip is made in the bar the clip being
held by being driven tightly into such groove or being soldered or screwed pinned or
riveted as mentioned with reference to Fig. 6 the use of screws or pins being
applicable more particularly to the example illustrated by Fig. 8. In Fig. 9 the clip
is made deeper so that the part which is attached to the bar comes below the face and
rests upon the back of the bar rivets screws or other fastenings or solder being used
in the attachment. In Fig. 10 the clip b is formed with legs or projecting parts g
which are passed through holes or slits in the bar and are clenched upon the back of
the same. Figs. 11 and 12 illustrate the method of formation of these legs. Each leg
is formed by separating a strip of metal on two sides and one end by means of a
cutter punch the strip remaining attached by the other end as indicated in Fig. 1.1.
The said strip is then bent at right angles as indicated in Fig. 12. Figs. 13 and 14
illustrate the attachment of the clip by means of grippers which are formed by
slitting at intervals the blank or strip of metal used in the formation of the clip and
turning parts of the sheet metal between such slits downward over the edge of the
bar and clamping them over the back corner of the bar as indicated in Fig. 13.
Other parts are turned in a contrary direction and serve to clamp the clothing to
the bar. This method of attachment might he used to secure the double clip 6 in
Fig. 1 to the bar. To render the attachment more secure the edges of the bar might
be nicked or recessed to receive the grippers has indicated by Fig. 15. Solder might
be used to render the attachinent more secure. In Fig. 16 the turned down parts are
passed through holes in the bar and in Fig. 17 they are screwed or pinned to the
edge of the bar. It will be seen that in all the examples the clips are secured to the
bar and held in position independently of the card clothing the general intention
being to secure the clips to the bar before applying the clothing so that in most or in
all cases the clips shall remain permanently upon the bar and serve to secure more
than one set of clothing to the bar excepting in cases wherein by reason of the clips
being broken or damaged it may be necessary to renew them. When it becoines
desirable to renew the clothing we propose to turn up the edges of the clips so as to
release the clothing. To effect this we may clamp the flat between two bars indicated
by k k in Fig. 18 such bars serving to support the backs of the clips. The edge of
each clip might then be raised by means of a plough or tool attached to a sliding or
travelling carriage. This method of releasing the clamps does not however come
within our claims hereunder. There might be an exception to the permanent attach-
ment of the clips to the bar in the cases wherein the double clip represented in Fig. 2
would be used. In such cases if considered to be advisable we might first attach the
clamp to the clothing and afterwards solder the clamp to the bar or attach it by
means of turn down pieces in the manner indicated when referring to Figs. 10 to 16.
Although we prefer to make each clip as long as the strip of card clothing or there-
abouts we might apply more than one clip upon each edge or side of the bar if
considered to be desirable.
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 combination of a carding engine flat bar with the sheet metal clips
attached to the bar prior to the application thereto of the card clothing substantially
as set forth.
(2) The sheet metal double clip interposed between the card clothing and the flat
bar and serving to secure such clothing to the bar substantially as set forth with
reference to Fig. 2 of the drawings.
(3) The sheet nietal clips or clamping plates secured to a flat bar in the indicated
manner whereby the said bar is adapted to receive and hold the card clothing sub-
stantially as set forth and indicated.

page_text: (4) The clips riveted screwed pinned or soldered or similarly secured to a flat
bar and formed to be closed down on to the margins of the clothing subsequently
applied to such bar so as to grip or hold the clothing in place substantially as set
forth and indicated.
(5) The sheet metal clips soldered to a flat bar and adapted to receive and hold the
card clothing substantially as set forth.
(6) The sheet metal clips attached to a flat bar by means of projecting legs or
turned down parts substantially as set forth with reference to Figs. 10 to 16 of the
drawings.
