Improvements in Apparatus for the Manufacture of Fasteners for
Securing Card Clothing to the Flats of Carding Engines.
We GEORGE ALEXANDER KENNEDY of the Firm of Horsfall & Bickham of
Bridgewater Works Pendleton in the County of Lancaster, Card Makers,
WILLIAM SENIOR and IRA Wood both of the same place, Mechanics, do hereby
declare the nature of this invention to be as follows:-
This invention relates to the manufacture of such fasteners for securing card
clothing to the flats of carding engines as are made with a flange provided with
teeth or spikes which pass through the foundation of the card clothing from the
back and the object of the invention is to provide apparatus by which the flange is
formed by bending up the flat strip of which the fastener is made and punching up
the spikes or teeth from the edge of such flange.
The apparatus is constructed as follows:-
Upon a suitable framework we mount a guide preferably fixed and preferably
made of two plates the upper one being slightly recessed for say about one quarter
of an inch (or more or less) to receive one edge of a strip of metal of which the
fastener is to be made, and which is of sufficient pliability and strength for the
purpose, the said strip of metal being brought from a convenient reel mounted on
or near to the said framework.
The other edge of this metal strip is held in a similar groove or recess in a
hinged jaw pivotted at the outer end so that it can be brought close to the fixed
guide at the inner end.
Between this jaw and the fixed guide is a small bending plate tapering from
below to a narrower edge and moved vertically by a short rod or arm passing
through a hole in the bed plate of the machine, and carried at the end of a lever
which is mounted on a horizontal pivot and prolonged beneath a suitable cam upon
a cam shaft mounted at one side of the machine and running the whole length of
the frame.
This bending plate is forced upwards against the underside of the strip of metal
before named, in order to bend up the metal and commence the formation of the
flange thereon. Close to the end of the fixed guide above described is a kind of
die or holder for holding one edge of the metal whilst a sliding die finishes the
formation of the flange.
This sliding die is actuated by a lever provided with a curved end which as it is
raised by a cam on the cam shaft acts upon the end of the sliding die and pushes it
forwards against the fixed die or holder.
The lower jaw of the fixed die or holder is movable upwards to grip the plate
while the sliding die is moved inwards; it is pressed upwards by a lever and a cam
on the cam shaft. The sliding die is connected to the pivotted jaw above named
and a spring pulls them away from the fixed die and the guide.
Immediately behind this flanging mechanism are the feeding jaws which work to
and fro between the said flanging mechanism and the apparatus for forming the
teeth or spikes upon the flange.
The feeding jaws are moved forward by a lever and cam on the cam shaft and a
spring brings them back again; they are opened and closed by the same lever and
a second cam on the cam shaft. When the flanged metal strip has been brought
forward it is held by a pair of fixed jaws beyond, which are closed by a suitable lever
and cam on the cam shaft.
The flanged metal strip then passes on between a sliding punch and die; the

page_text: latter is brought in against one side of the flange by a cam or eccentric on a short
rocking shaft actuated by a lever worked by a sliding rod and a cam on the cam
shaft. The punch is moved inwards by a sliding plate connected to the clip of an
eccentric or cam on the cam shaft. The punch is so formed that it cuts a long
pointed strip from the edge of the flange and bends it in a direction parallel with
the metal strip i.e., at right angles to the flange. A spring mounted upon the
punch comes in contact with an adjustable peg on the die and is brought down
thereby to set the spike or tooth (formed by the said punch) in this vertical and
parallel position.
The strip as it is flanged and spiked by the above mechanism travels onwards
along a long grooved bracket or support at the delivery end of the machine, where
(if desired) an automatic cutter may be applied to cut or sever any required length
of fastener from the finished strip.

Improvements in Apparatus for the Manufacture of Fasteners for
Securing Card Clothing to the Flats of Carding Engines.
We GEORGE ALEXANDER KENNEDY of the Firm of Horsfall & Bickham of
Bridgewater Works Pendleton in the County of Lancaster, Card Makers,
WILLIAM SENIOR and IRA WOOD both of the same place, Mechanics, 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 to the manufacture of such fasteners for securing card
clothing to the flats of carding engines as are made with a flange provided with
teeth or spikes which pass through the foundation of the card clothing from the
back, such fasteners forming the subject of Letters Patent No. 8407 granted to
William Senior, Edward Hughes, Ira Wood, Washington Hemingway, and
George Alexander Kennedy, and dated April 26th, 1893; and the object of the
invention is to provide apparatus by which the flange is formed by bending up the
flat strip of which the fastener is made and punching up the spikes or teeth from
the edge of such flange.
Our invention will be readily understood from the following description on
reference to the accompanying two sheets of drawings.
On Sheet 1 Fig. 1 is an end view and Fig. 2 a plan of our improved apparatus.
On Sheet 2 Figs. 3, 4, 4^, 4B, 5, 54, 5 and 6 are detached views hereafter
particularly referred to.
The apparatus is constructed as follows:-
Upon a suitable framework we mount a guide preferably fixed and preferably
made of two plates a a', the upper one a being slightly recessed for say about one
quarter of an inch (or more or less) see Fig. 1, to receive one edge of a strip of
metal of which the fastener is to be made, and which is of sufficient pliability
and strength for the purpose, the said strip of metal being brought from a con-
venient reel (not illustrated on the drawings) mounted on or near to the said
framework.
The other edge of this metal strip is held in a similar groove or recess in a
hinged jaw b pivotted at the outer end at 6' see Fig. 2 so that it can be brought close
to the fixed guide a a' at the inner end.
Between this jaw band the fixed guide a a' is a small bending plate c (Fig. 1)
tapering from below to a narrower edge and moved vertically by a short rod or

page_text: arın c¹ connected thereto and passing through a hole in the bed plate y of the>
machine, and resting on and carried at the end of a lever c³ which is mounted on a..
horizontal pivot c and prolonged beneath a suitable cam 1 upon a cam shaft z
mounted at one side of the machine and running the whole length of the frame, as
seen at Fig. 2.
This bending plate c is forced upwards against the under side of the strip of
metal a before named, in order to bend up the metal and commence the formation
of the flange thereon. Close to the end of the fixed guide a a' above described is
a kind of die or holder d d* for holding one edge of the metal whilst a sliding
die d finishes the formation of the flange.
This sliding die d' is actuated by a lever d³ provided with a curved end which as
it is raised by a cam 2 on the cam shaft z acts upon the end of the sliding die d¹
and pushes it forwards against the fixed die or holder d d*.
The lower jaw d* of the fixed die or holder is movable upwards to grip the
plate while the sliding die d' is moved inwards; it is pressed upwards by a
lever d³ and a cam 3 on the cam shaft z (see Fig. 6). The sliding die d¹ is con-
nected to the pivotted jaw b above named (see Fig. 2) and a spring d¹ pulls them
away from the fixed die d and the guide a.
Immediately behind this flanging mechanism are the feeding jaws e e¹ which work
to and fro in the slides e* (see also Fig. 5), between the said flanging mechanism
and the apparatus for forming the teeth or spikes upon the flange.
The feeding jaws e e' are moved forward by a lever and cam 4 on the cam
shaft and a spring e brings them back again, they are opened by the spring e
(see detached side view Fig. 5A) and closed by the lever e² and a second cam 5 on
the cam shaft z (see Figs. 2 and 5). When the flanged metal strip has been
brought forward it is held by a pair of fixed jaws ff' (see also detached view
Fig. 5B) beyond, which are closed by a suitable lever fi and cam 6 on the cam
shaft z.
The flanged metal strip a then passes on between a sliding punch g and die h,
the latter is brought in against one side of the flange by a cam ¹ or eccentric on
a short rocking shaft 2 actuated by a lever h² worked by a sliding rod h and a
cam 7 on the cam shaft z (see also Figs. 3 and 4). The punch g is moved inwards
by a sliding plate g' connected to the clip g² of an eccentric or cam 8 on the cam
shaft z.
The end of the punch 9 and the die hare so formed (as shewn detached
and enlarged at Figs. 44 and 4B respectively) that the said punch cuts a long
pointed strip from the edge of the flange and bends it in a direction parallel with
the metal strip i.e.; at right angles to the flange. A spring mounted upon the
punch comes in contact with an adjustable peg on the die and is brought down
thereby to set the inner side of the spike or tooth (formed by the said punch) in
its vertical and parallel position. Or this setting of the spikes may be accomplished
as shewn on Figs. 2 and 3, by a spring presser i acted upon by a set screw or pin 2¹
upon a sliding setter attached to the sliding plate g' and moving therewith.
A spring (Figs. 2 and 4) then withdraws the die h into the recess h* of
the cam which is oscillated by the cam shaft z (as above described) for this
purpose.
The strip as it is flanged and spiked by the above mechanism travels onwards
along a long grooved bracket or support k at the delivery end of the machine,
where (if desired) an automatic cutter may be applied to cut or sever any required
length of fastener from the finished strip.
(see Fig. 2) is an adjustable guide for counteracting the tendency of the
punching mechanism to bend the strip of metal and ensuring its delivery in a
straight condition to the said bracket or support k.
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 :-
The general construction and arrangement of apparatus for the manufacture

page_text: of card fasteners, operating substantially as hereinbefore described and illustrated
by the annexed drawings.
