Improved Apparatus for Feeding Wire to Card-setting Machines, or
to Machines for Punching or Forming Saw Teeth or Serrations
on Wire.
We, EZRA SYKES and DAVID SYKES, of the firm of John Sykes and Sons, of
Turnbridge Machine Works, Huddersfield, Yorkshire, Machine Makers, and WILLIAM
HEATON KELLETT, of the same place, Manager, do hereby declare the nature of this
invention to be as follows :-
:-
This invention refers to certain improvements in the means for feeding wire to
card setting machines, or to machines for punching or forming saw teeth or serrations
on wire employed for opening or carding fibrous substances; our object in such
invention being to render the feed motion to such wire more regular and effective in
its action, also to reduce concussion of the parts so that little or no noise or vibration
is caused when the feed motion is in operation, and to simplify the apparatus whereby
it may be easily removed from or attached to the machine.
In order to carry out our invention, we dispense with the grooved cam and pivotted
feeding lever, together with certain other parts forming the present feeding mechanism,
and in lieu thereof, we employ a cam or tappet, mounted on the main shaft of the
machine, and two sliding bars arranged at right angles to each other upon the table
or top of the machine. "One of these sliding bars is inclined at its extremity, and
when caused to slide end wise by the action of the cam or tappet thereon, the said
inclined surface bears against a corresponding inclined surface projecting from the
side of the other or feeding bar, whereby the latter is moved or slided in a direction
at right angles to the former, and feeds a length of wire (equal to the extent of its
motion in that direction) forward to the machine, where it is subsequently cut, bent,
and set into the cards; or in the case of saw teeth, the serrations are punched or
stamped out in the usual manner; the return movement of the sliding bars is effected
or assisted by means of a spiral spring connected to the feeding bar and to the frame
or fixed part of the machine.
In connection with the feeding bar is a suitable device which is operated by lever
or rod and a second cam mounted on the main shaft at each extremity of motion of
the said bar for the purpose of gripping the wire during the forward movement of
the feeding bar in order that it may be fed to the machine, and also for releasing its
hold upon the wire during the backward movement of the feeding bar, as is the case
in the existing feeding mechanism.
By the means above set forth, the parts work smoothly and silently, causing little
or no vibration; the motion is simple and effective, and can be easily removed from
or connected to the machine when required.

Improved Apparatus for Feeding Wire to Card-setting Machines, or
to Machines for Punching or Forming Saw Teeth or Serrations
on Wire.
Wo, EZRA SYKES and DAVID SYKES, of the firm of John Sykes and Sons, of
Turnbridge Machine Works, Huddersfield, Yorkshire, Machine Makers, and WILLIAM
HEATON KELLETT, of the same place, Manager, 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 :-
1
This invention refers to certain improvements in the means for feeding wire to card

page_text: setting machines, or to machines for punching or forming saw teeth or serrations on
wire employed for opening or carding fibrous substances; our object in such invention
being to render the feed motion to such wire more regular and effective in its action,
also to reduce concussion of the parts so that little or no noise or vibration is caused
when the feed motion is in operation, and to simplify the apparatus, whereby it may
he easily removed from or attached to the machine.
In order to carry out our invention, we dispense with the grooved cam and pivotted
feeding lever, together with certain other parts forming the present feeding
mechanism, and in lieu thereof we employ other mechanism better adapted for the
purpose.
Such being the nature and object of our invention, we will first of all shew the
application of our improvements to an ordinary card setting machine, of which Fig. 1
is plan view; a being the main driving shaft, upon which are fixed cams b for operating
knife c, crown d, tongue e, instruments well known and used for cutting, bending, and
setting wire card teeth, such parts, however, forming no portion of our invention.
frepresents the winch or pulley around which the wire g is placed, being nipped or
taken hold of by the two pieces of metal and i, carried at the end of a sliding bar j,
shewn more clearly in Fig. 2, which is section of Fig. 1. One of the pieces of metal
or nippers i is loose in a socket formed in the end of the sliding bar j, but at a given
time the point of the adjusting screw k is forced against the loose piece i so as to nip
the wire, and this is performed by means of the instrument or spring bar 1, which is
forced in the direction against the wire by means of the flat spring m, but the point
of the set screw k is withdrawn from the loose piece i (when it is necessary to release
the wire) by means of the vertical pin connected to the end of a bar o made to
slide or reciprocate away from the wire by the camp on the main shaft, the flat spring m
forcing the parts back again against the wire.
The wire is fed forward to the instruments for forming the card teeth by means of
the sliding bar j which is made to advance by means of another sliding bar
9 made
to reciprocate towards the sliding bar; by means of a cam r also fixed on the main
shaft, shewn in Fig. 1 and also in Fig. 3, which is end view of the former. The
sliding bar q carries an antifriction bowl s, and it is forced against the inclined but
adjustable surface t binged at u to an arm projecting from the sliding bar j, so that
at every forward stroke of the sliding bar 7, the wire holding bar j is made to advance
to present the necessary length of wire to the card setting instruments, the said sliding
bar being drawn backwards by spiral spring v. Fig. 4 is an enlarged view of the
hinged inclined surface t, the angle of which can be adjusted by the set screw w,
the purpose of making the angle more or less acute in order to lengthen or shorten
the feed. Fig. 5 is end view of Fig. 4. Figs. 6 and 7 are cross section and
elevation of the adjustable part t shewing the position of pulley & carried on the end
of the reciprocating bar q.
for
By the means above set forth, the parts work smoothly and silently, causing little or
no vibration; the motion is simple and effective, and can be easily removed from or
connected. to the machine when required.
We will now shew the application of our invention to a machine for punching
serrated or saw teeth from flat strips or continuous narrow lengths of steel or other
metal, Fig. 8 being side view thereof and Fig. 9 front view of same. c and d represent
two vertical cutters employed to cut the serrated strip g; but such cutting instruments,
and the manner of working them, form no part of our invention. The strip of metal
passes underneath a spring jaw h connected to a sliding bar j, being pressed down-
wards so as to nip the wire when it may be fed forward by means of eccentric e, which
is made to act on the upper end of the bar f, hinged at i, but the pressure of the
foot of such bar is removed from the jaw h, when the eccentric permits it, by means
of the spiral springs 1, and this is performed much in the same manner as that
already described with regard to card setting machines. In this case the sliding
bar carries an inclined surface t hinged at u and made adjustable by the set
The inclined surface is operated upon for the purpose of forcing the bar j
forward to feed wire by means of the antifriction bowls carried on the lower end of
screw w.

page_text: the vertical rod g which is forced downwards by an eccentric or cam on the main
shaft a, the spiral spring m being employed to lift the bowl off the inclined surface t.
It will therefore be seen that as the bar 9 reciprocates up and down, the bowl is
forced down against the inclined surface, causing the barj to move forward for the
purpose of feeding the required length of wire, such said bar j being brought back
by the spiral springs v, and this goes on continuously as long as the main shaft
revolves. It will be understood that the length of wire fed at each stroke can be
varied by the adjusting set screw w which gives more or less angle to the inclined
surface, consequently more or less movement is imparted to the bar which
carries it.
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 :-
Firstly. In card setting machinery, the use of the sliding bars j and q for feeding
wire, arranged and operated in the manner shewn and described.
Secondly. In card setting machines, the use of sliding bars j and q in combination
with the adjustable inclined surface t employed in the manner and for purposes
described.
Thirdly. In card setting machines, the device herein shewn and described for
nipping, holding, and releasing the wire, substantially as described and shewn in the
drawings.
Fourthly. In machines for punching serrated or saw teeth, the use of the sliding
bars and q for feeding strips of metal, arranged and operated in the manner shewn
and described.
Fifthly. In serrated or saw teeth punching machines, the use of sliding bars j
and q in combination with the adjustable inclined surface t employed in the manner
and for purposes described.
Sixthly. In serrated or saw teeth punching machines, the device herein shewn and
described for nipping, holding, and releasing the wire, substantially as described and
shewn in the drawings.
