PROVISIONAL SPECIFICATION.
A Method of and Mechanism for Feeding a Certain Class of Wire
into Card-setting Machines.
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, broadly stated, consists in adapting the feed mechanism of card
setting machines to feed card wire made in two sections say for example alternately
round or of other section for the base or lower portion of each tooth and oval
elliptical flat or of other section for the point or carding portion of the tooth. Such
card wire may either be formed in two sections by rolling as described in the
Specification to Letters Patent No. 12185 of 1886 granted to me or may be formed
of two sections by other methods of production.
In applying my invention to the feed mechanism of a card setting machine 1
dispense with the ordinary nipping jaws of the travelling feeding clip now employed
to tightly grip and feed forward card wire of one uniform section and I employ a
pair of jaws or equivalents which embrace loosely or approach nearly, without gripping,
one section of the said biform card wire.
The front edges of these jaws when the clip mechanism is moved forward, bear
against the projecting shoulder of the next section and so the wire is fed forward by
the pressure of the jaws against said shoulder in contradistinction to the ordinary
mode of feeding forward wire of any uniform section by tightly gripping it in the
travelling clip. While sufficient wire to form a tooth is being cut off the jaws of the
feeding clip open slightly and pass back over the next section and then ro-close ready
to repeat the feeding operation as above described.
The jaws or equivalents of the feeding clip may be opened and closed and moved
forward and backward as required by the usual or any suitable known mechanical
contrivance.

A Method of and Mechanism for Feeding a Certain Class of Wire
into Card-setting Machines.
1, WILLIAM WALTON, of Haughton Dale Mills, Denton, in the County of Lancaster,
Wire Card Manufacturer, do hereby declare the nature of this said 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, broadly stated, consists in adapting the feed mechanism of card
setting machines to feed card wire made in two sections say for example alternately
round or of other section for the base or lower portion of each tooth and oval elliptical
flat or of other section for the point or carding portion of the tooth. Such card wire
may either be formed in two sections by rolling as described in the Specification to
Letters Patent No. 12185 of 1886 granted to me or may be formed of two sections
by other methods of production.
In applying my invention to the feed mechanism of a card setting machine I
dispense with the ordinary nipping jaws of the travelling feeding clip now employed to
tightly grip and feed forward card wire of one uniform section and I employ a pair

page_text: of jaws or equivalents which embrace loosely or approach nearly, without gripping,
one section of the said biform card wire.
The front edges of these jaws when the clip mechanism is moved forward, bear
against the projecting shoulder of the next section and so the wire is fed forward by
the pressure of the jaws against said shoulder in contradistinction to the ordinary
mode of feeding forward wire of any uniform section by tightly gripping it in the
travelling clip. While sufficient wire to form a tooth is being cut off the jaws of the
feeding clip open slightly and pass back over the next section and then re-close ready
to repeat the feeding operation as above described.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying Sheet of Drawings reference being had to
the figures and letters marked thereon.
Figure 1 is a plan,
Figs. 2 and 3 are opposite side views,
Fig. 4 is a front end view of Fig. 1, and
Fig. 5 is a longitudinal section of my improved mechanism for feeding a certain
class of wire into card setting machines.
In these views a designates the feed lever mounted to slide upon the feed spindle
not shown of an ordinary card setting machine; to the lever a is secured the spring
plate which is formed with slideways in which are fitted two jaws c and d
respectively for feeding the biforin card wire. The jaw c is movable and is connected
by a small spring d to a projection on the plate ; while the jaw d is fixed by a
screw e and on the jaw d is fitted an adjustable piece also held in position by the
screw e and slotted at the point where the latter passes through it the piece f being
adjustable by means of a screw g which screws into the jaw d.
To the feed lever a is secured a stud which is actuated by the feed tappet, not
shown, in the usnal manner to raise that end of the feed lever and cause the other
end which is bevelled at a to press against the correspondingly bevelled end of the
jaw c and force its other end against the adjustable stop piece f which is set so as to
leave a certain space between the jaws c and d according to the size of the wire to be
fed. The same tappet also traverses the feed lever a along the spindle upon which
it is mounted in the usual way.
In Fig. 5 the jaw c and stop piece are shown in contact, the biform card wire to
be fed forward lying below the piece fand between the jaws c and d the parts being
so adjusted that the flattened portion of the biform card wire lies between the jaws c
and d without being gripped by them.
The operation is as follows:-A ring of biform card wire is placed on the swift and
its end passed forward between the jaws c and d to the cutting off mechanism of the
card setting machine; when the machine is started the feed tappet acts upon the
stud to depress the front or bevelled end a² of the feed lever and move the jaw c
against the adjustable stop piece f; the continued movement of the feed tappet then
traverses the feed lever a along its spindle the jaws c and d sliding over the flattened
portion of the wire until they meet the shoulder of the round or other section against
which they bear and so feed forward the wire until the traverse of the feed lever
ceases. The length of wire to form a card tooth is then cut off and the feed tappet
allowing the stud to descend the spring c¹ instantly withdraws the jaw c so that as
the feed lever returns the jaws c and d pass over the round portion of the wire without
moving it until the jaws are again closed upon the flattened portion by the action of
the feed tappet. and the feed motion is continued as before described.
The jaws or equivalents of the feeding clip may be opened and closed and moved
forward and backward as required by the usual or any suitable known mechanical
contrivance.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is
1. The herein described method of feeding biform card wire into card setting

page_text: machines by means of a travelling feeding clip the jaws of which are arranged to close
over and embrace loosely one section say the flat of the card wire and to feed the wire
forward by pressure against the shoulder of the next or round section.
2. The combination and arrangement of parts constituting a travelling feeding clip
for feeding biform card wire into a card setting machine substantially in the manner
herein described and as illustrated by the accompanying Drawings.
Dated this 11th day of April 1890.
