PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Flats for Carding Engines.
I, WILLIAM WALTON, of Haughton Dale Mills, Denton, in the County of Lancaster,
Wire Card Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in the manufacture of flats for travelling flat
carding engines and my improvements consist essentially in attaching the card
clothing to strips of thin sheet metal or other suitable material which strips are in
their turn secured to the ordinary cast iron flats.
The chief advantage of this mode of clothing the flats is that the strips of card
clothing with the metal or other backs can be sent out ready to be secured by rivets
or otherwise to the ordinary iron flats when the latter need re-clothing and this without
necessitating the return or removal of the flats from the spot where the engine is
working.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Flats for Carding Engines.
I, WILLIAM WALTON, of Haughton Dale Mills, Denton, in the County of Lancaster,
Wire Card Manufacturer, 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:-
My invention relates to improvements in the manufacture of flats for travelling flat
carding engines, and my improvements consist essentially in attaching the card
clothing to strips of thin sheet metal or other suitable material which strips are in
their turn secured to the ordinary cast iron flats.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying two sheets of drawings reference being had
to the figures and letters marked thereon.
Fig. 1 represents a strip of metal a which may be of soft steel or other suitable
metal or material stamped or cut out to the shape shown so as to leave cramps, claws
or projections a' for the purposes of my invention.
Fig. 2 is a sectional edge view of the same on the line A B Fig. L.
Fig. 3 is a view of the strip a with a card fillet stretched and mounted upon it.
Fig. 4 is a similar view to Fig. 3 but with the addition of a flat to which the strip a
and fillet bare to be secured.
Fig. 5 is a side view of part of the flat c with the strip a and card fillet b secured
in position thereon, and
Fig. 6 is a sectional view of the same taken on the line C D Fig. 5.
Figs. 7 and 8 are two views of a strip of metal a to which the card fillet b is to be
secured.
Fig. 9 shows the fillet 6 stretched and fastened to the strip of metal a ready for
attachment to the flat c as shown in the two views Figs. 10 and 11 the latter being a
section on the line E F Fig. 10.
Fig. 12 is a view of a strip of metal a such as sheet steel or other suitable
material. Fig. 13 represents in front and side view one of the cramps a' which in
this case are separate pieces and Fig. 14 represents the card fillet
fastened upon the strip a and the cramps a' also fixed in position.
stretched and

page_text: Figs. 15 and 16 represent in side and sectional end view respectively the strip a
secured with the fillet b by means of the cramps a¹ to the flat c.
Fig. 17 is a plan and Fig. 18 a side view of a strip of metal formed with cramps a¹
and also with tongues at the latter securing the fillet 6 to the strip a
Fig. 19 shows the fillet secured to the strip by the tongues al and Figs. 20 and 21
represent a flat c with the combined fillet and strip a secured thereto by the
cramps a¹.
Figs. 22, 23 and 24 illustrate the use of a strip of pasteboard or other material d
placed between the strip a and flat c to compensate for the projecting rivet heads.
Similar letters refer to similar parts throughout the several views.
Referring first to Figs. 1 to 6 in which a designates the strip of soft metal or other
suitable material to which the card fillet b, after stretching is secured by rivets,
eyelets or in any other convenient manner. If necessary the strip a is counter-
sunk in order to receive the rivet heads and enables the strip to bed evenly upon
the flat.
The strip a in this case is shown formed with cramps, claws or projections a¹ for the
purpose of securing the strip a with the fillet b. after the latter has been stretched and
mounted upon it, to the flat c.
A convenient sequence of operations to secure the combined strip a and fillet 6 to
the flat c is first to bend up the cramps a¹ on one side of the trip as shown in
Fig. 4 then when placed upon the flat c to bend up the cramps a' at the other side
as shown in dotted lines in the same view and subsequently to turn the cramps
over the edges of the flat c as shown in Figs. 5 and 6 both rows of cramps being
bent over either simultaneously or separately.
a¹
Referring now to Figs. 7 to 11 the strip of metal a is made wider in the main
portion and the marginal parts all between the cramps al are bent over the fillet b,
see Fig. 9 after the latter has been stretched and secured to the strip a in any con-
venient manner; the cramps a are then bent over the flat as shown in Figs. 10
and 11 by a subsequent operation, to fasten the combined parts together.
In Figs. 12 to 16 the strip a which may be of sheet metal or any other suitable
material is the same width as the flat to which it is to be subsequently attached ;
the fillet is stretched and then secured to the strip a by rivets as shown or in
any other convenient manner, some of the rivets or equivalents passing through
each cramp a' and thereby securing it to the fillet and the strip, the combined strip,
fillet and cramps being fixed upon the flat e by bending over the cramps a..
When card fillet is mounted upon a strip such as that shown in Fig. 12 the
cramp a' may be dispensed with and the strip a secured to a flat by means of
rivets or equivalents by any of the various modes by which card fillet is now fastened
to a flat.
In Figs. 17 to 21 the strip a is made of metal such as soft sheet steel and in
addition to the cramps a¹ as before described it also has tongues a punched or
otherwise formed out of the metal as clearly shown in Figs. 17 and 18. In Fig. 18
the tongues a are shown bent at right angles to the strip a and in position for
the foundation of the card fillet b to be stretched over and forced down upon the
tongues a which penetrate the foundation and are then turned back and into the
foundation again see Fig. 19 in order to secure the fillet to the strip a.
The com-
bined fillet band strip a are then fastened to the flat c as before described and as
illustrated in Figs. 20 and 21.
Figs. 22, 23 and 24 represent an arrangement very similar to that described with
reference to Figs. 1 to 6 the only difference being that in this case a strip of card-
board or other suitable packing material d is placed between the strip a and the
fillet c to compensate for the rivet heads and this strip has holes d punched in
it, see Fig. 23, to receive the heads of the rivets by which the fillet b is secured to
the strip a.
The object of this arrangement is to form a level bed without necessitating any
countersinking of the strip a.
Although I have shown the strips a in each of the arrangements illustrated by

page_text: Figs. 1 to 6 and Figs. 17 to 21 and Figs. 22 to 24 with cramps or projections a¹
for clamping it on to the flat it is evident that the cramps a' could be dispensed
with and by using a sufficiently broad strip its edges could be clamped over the
edges of the flat from end to end of its clothed surface to secure the parts
together.
Whenever the width of the flat necessitates it some metal may be removed upon
one or both sides as required in order to make room for the cramps or equivalents
by which the combined strip and fillet is secured to the flat.
It is also evident that other means for securing the strip or back on which the
fillet is mounted to the flat may be adopted without departing from my invention.
The chief advantage of this mode of clothing the flats is that the strips of card
clothing or fillets with the metal or other backs can be sent out ready to be secured
by cramps a rivets or otherwise to the ordinary iron flats when the latter need
re-clothing and this without necessitating the return or removal of the flats from the
spot where the engine is working.
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 :-
1. A fillet or strip of card clothing stretched and mounted upon a strip of sheet
metal or other suitable material the combined fillet and metal or other strip being
subsequently secured to an ordinary flat for the purpose specified.
2. A strip or backing upon which card fillet is stretched and fastened the edges or
marginal projections on said strip forming means for securing the combined clothing
and strip to a flat.
3. A strip of suitable metal upon which a card fillet is stretched and secured
thereto by tongues formed out of said metal the combined metal strip and fillet being
subsequently secured to a flat as shown and described or in any other convenient
manner.
4. The several combinations of the metal or other strip a the cramps a¹ or
equivalents, the card fillet and the flat c substantially as and for the purposes heroin
set forth.
