PROVISIONAL SPECIFICATION.
Improvements in Carding Engine Flats and in Securing Oard
Clothing thereto.
ALFRED HITCHON of Globe Iron Works Accrington Machine Salesman do
hereby declare the nature of this invention to be as follows:--
This invention relates to improvements in the carding engine flats described in
the Specifications of Letters Patent 7620 of 1888, 5540 of 1889 and 5844 of 1892
and is designed with the object of effecting a more perfect mounting and securing
of the card clothing to the flat.
In 5540 of 1889 the flat bar is bevilled or recessed the object of the bevilling off
or recessing is to provide for the extra thickness of the edges of the foundation
by reason of the metal edgings enclosing and encasing the raw edges of the card
clothing.
The object of my invention is to make use of similar edges to those described
in 5540 of 1889 in connection with metallic strips described in Specification 5844
of 1892. In so doing 1 luy the foundation of the card clothing against the iron
flats with a stronger bearing and as little stretching as possible thus giving
elasticity to the card wires.
In order to attain this object I bevil the flats off froin the part where the backs
of the carding wire are to lay to the edges of the flat where the clamps come in
contact thus avoiding too great a strain on the foundation fabric and at the same
time providing a better means of enabling the backs of the carding wire always to
be in contact with the flat.
I propose after having partially stretched and mounted the card clothing within
the side pieces of bed described in my 5844 Specification to slide the card clothing
together with its two metallic strips endways to my proposed bevilled iron flat
which is of similar width to the partially stretched cloth proposed to be slidden-
and then completing the securing of the card clothing to the bevilled flat by
means of the rolling machines shewn in Specification 7620 of 1888 which not
only fastens the metallic strips and clothing to the flat but gives a further
stretch to the card clothing on account of the bevilled edge being formed on
the flat.
Dated this 26th day of April 1893.

Improvements in Carding Engine Flats and in Securing Card
Clothing thereto.
ALFRED HITCHON Globe Iron Works Accrington Machine Salesman do
hereby declare the nature of this invention and in what manner the same is to
he performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to improvements in the carding engine flats described in
the Specifications of Letters Patent 7620 of 1888, 5540 of 1889 and 5844 of 1892

and is designed with the object of effecting a more perfect mounting and securing
of the card clothing to the flat.
In 5540 of 1889 the flat bar is bevilled or recessed the object of the bevilling off
or recessing is to provide for the extra thickness of the edges of the foundation by
reason of the metal edgings enclosing and encasing the raw edges of the card
clothing.
The object of my invention is to make use of similar edges to those described
in 5540 of 1889 in connection with metallic strips described in Specification 5844
of 1892. In so doing I lay the foundation of the card clothing against the iron flats
with a stronger bearing and as little stretching as possible thus giving elasticity
to the card wires.
In order to attain this object I bevil the flats off from the part where the backs
of the carding wire are to lay to the edges of the flat where the clamps come in
contact, thus avoiding too great a strain on the foundation fabric and at the same
time providing a better means of enabling the backs of the carding wire always to
be in contact with the flat.
I propose after having partially stretched and mounted the card clothing
within the side pieces of bed described in my 5844 Specification to slide the
card clothing together with its two metallic strips endways to my proposed
bevilled iron flat which is of similar width to the partially stretched cloth
proposed to be slidden-and then completing the securing of the card clothing
to the bevilled flat by means of the rolling machines shewn in Specification 7620
of 1888 which not only fastens the metallic strips and clothing to the flat but gives
a further stretch to the card clothing on account of the bevilled edge being formed
on the flat.
•
In order that my invention may be more fully understood I make reference to
the accompanying drawings.
Fig. 1 shews the card clothing A and metallic strips B partly slided on to the
iron flat C having bevel edges E.
Fig. 2 is a sectional view of Fig. 1.
Fig. 3 shows the last operation of fixing the card clothing closely to the face of
the flat. The card clothing A and metallic strips B are being clamped to the flat C
by rollers D. The card clothing is fixed on the face of the flat with a minimum
amount of stretch through the turned in edges of the two metallic strips which
enclose the selvage of the foundation fabric having a tendency to move outwardly
and in an opposite direction and bed better against the face of the flat owing to
being on the bevel edges of the flat when the strips are being completed into
clamps. The detail parts of the rolling machine are illustrated in Patent
No. 7620, A.D. 1888, Figs. 9 and 10. Only the rollers D placed in position
for binding the outer edge of the metallic strip around the back edges of the iron
flat for securing the card clothing to same are shown in the accompanying
drawings.
Fig. 4 is a sectional view of the iron flat with the card clothing and strips slid on
and being clamped thereto by the rollers D.
Fig. 5 is an enlarged view of Fig. 2 so as to show more clearly the bevelled
edges E of the iron flat.
Fig. 6 is an enlarged sectional view of the flat with card clothing and clamps
completely bent.
Fig. 7 shews a piece of the metallic strip B.
Having now particularly described and ascertained the nature of this my inven-
tion, and in what manner the same is to be performed I declare that what I
'claim is
Firstly. Metallic strips or clips as illustrated and described in Patent granted to
.me No. 5844 in 1892 in combination with bevel edged flat as illustrated in the
accompanying sheet of drawings.

page_text: Secondly. The bevel edged flat as illustrated with the clamps B attached to the
edges of the card clothing first slided on the face of the flat and then the selvage
edges of the foundation fabric pressed on the bevel inclined edges of the flat
SO as to maintain the security of the card clothing adhering closely to the
flat without undue stretch whereby more flexibility is given to the carding wire.
