Improvements in or applicable to Apparatus for Wrapping Card
Fillets on the Cylinders of Carding Engines.
I FREDERICK GALE DRANSFIELD of 31 Gower Street Oldham in the County
of Lancaster, Card Nailer, 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 especially to that kind of apparatus, for wrapping card
fillets on the cylinders of carding engines, which consists principally of a tension
drum around which the fillet is passed before being wrapped on the cylinder. The
object of the invention being to avoid injury to the wire consequent upon pulling
the fillet around and over the surface of the drum aforesaid.
The nature of my invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference
to the annexed sheet of drawings and the following explanation thereof.
Fig. 1 on the annexed drawings is a side elevation, Fig. 2 a plan view, and
Fig. 3 a vertical section of my improved apparatus.
The invention consists principally in substituting for the said drum a base
plate a provided with two ends or brackets b, or equivalent means for supporting a
set of suitably arranged fixed bars, (say) three bars c arranged in a triangle as
shown.
d is the feed box with its spring e and hand screw f for regulating the pressure
or tension; the shoe or platen g, which presses on the card fillet, I make shorter
than usual and stiffened with two webs g+, and I thus am enabled to put a more
even tension upon the surface of the fillet beneath the said shoe g+.
The card fillet h from the skip or basket passes first through the feed box d
under the shoe or platen g, and is then coiled twice (or more) round the three fixed
bars c, then outside and partially round a narrow crescent shaped guide i to the
cylinder on which it is to be wrapped.
The guide i is not a fixture but is carried by a plate & capable of sliding through
one of the fixed bars c (see Fig. 3), and is pressed outwards by a coiled or other
spring or springs I carried in the opposite fixed bar and, if required, by another
spring + as shown. This spring or springs + is or are capable of resisting the
utmost tension to which the fillet h can be subjected, and by means of an arm m
attached to the plate k, (by a pin sliding through a slot * or otherwise), and
connecting it to an index finger n (see Fig. 1), the spring or springs 11+ is or are
used to indicate on a graduated quadrant o the amount of tension which is being
put upon the fillet as it is laid.
By the use of this improved apparatus I am thus enabled to obtain an even
tension on the fillet as it is stretched over the fixed bars c, and as there are only a
few points of friction against the wire surface, the latter will not be liable to be
disturbed or disarranged thereby as is the case at present when the fillet is coiled
round and pulled over the continuous surface of a drum.
Having now particularly described and ascertained the nature of my said inven-
tion I wish it to be understood that what I claim is
1. In apparatus for wrapping card fillets on the cylinders of carding engines, the
arrangement of a set of fixed bars in a suitable frame in connection with a feed

page_text: box, substantially in the manner hereinbefore described and illustrated by the
drawings annexed and
2. I claim in connection with such or similar apparatus, the combination of the
tension indicating device herein before described and illustrated by the said
drawings.
Dated this Thirteenth day of November 1894.
