as are Used in the Preparation of Fibrous Materials.
I CHARLES MOSELEY of the Chapelfield Works Manchester in the County of
Lancaster, Manufacturer do hereby declare the nature of this invention to be as
follows:-
This Invention relates to the manufacture of Cards such as are employed in the
treatment of fibrous materials and has for its object to expedite, and consequently lessen
the cost of, the said manufacture. With this object the machinery apparatus or means
employed in the manufacture of the cards is so arranged that two or more teeth are
simultaneously inserted into the backing or foundation material. The apparatus for
this purpose may be arranged so as to continuously or intermittently feed the wire or
wires from which the card teeth are to be made; to grip or seize the said wire or
wires at as many points as there are teeth to be cut; to cut the wire or wires to
lengths corresponding or equal to the respective total lengths of the completed teeth;
to bend the teeth to the form or approximate form required for their insertion into the
foundation material; to convey the teeth to the position for insertion in the foundation
and if required to pierce the foundation with holes for the said insertion and to insert
simultaneously two or more teeth into the foundation, the foundation being held
stationery during the said insertion and, between the periods of such insertion of the
teeth a linear transverse or diagonal motion being imparted to the foundation to bring
it into the required position for the insertion of the following sets of teeth. Means are
also provided for giving the teeth the necessary amount of inclination when they are
required to be bent.
The Invention is not limited to any one precise mechanical arrangement of details
nor to the performance of the operations in the order or sequence herein before
mentioned and if desired some of the operations may be performed by mechanism
independent of that which performs other of the operations.
I will describe generally the nature of arrangements by which the Invention may
be effected.
The wire or wires from which the teeth are to be made is or are fed by rollers having

page_text: most
intermittent rotary motion or by suitable. clutching or gripping devices, having
intermittent reciprocal motion and so combined or arranged and actuated that the
clutches or grippers seize the wire or wires and convey or feed it or them in one
direction only and hold them stationary on the return stroke. The amount of rotary
or rectilinear motion of the feeding device is so governed or controlled that the total
length of wire or wires fed is equal or about equal to the total lengths of the teeth to
be cut therefrom at one operation. The wire or wires is or are seized and held by
tongs nippers dies or their equivalent at points corresponding to the central parts of
the future teeth and then cut by knives shears or by other similar means to the lengths
required for the formation of the teeth. The short lengths of wire are
conveniently bent while still held by the tongs nippers or dies by turning or bending
both the ends projecting from the jaws or dies at right angles to the part held. The
teeth so formed and whilst still held by the tongs nippers or dies are conveyed to the
foundation material for insertion or the said teeth may be so conveyed or fed by other
tongs nippers dies or their equivalent or by through or over tubes channels guides or
supports but always in such a manner that the points of the teeth arrive in their proper
positions relatively to the foundation material through which they are to be inserted
or fixed. If holes are required to be pricked through the foundation material for the
passage of the points of the teeth this may be done by needle points mounted at
the desired distances and relative positions upon a plate bar or rod and brought at the
requisite times to the plane to be occupied by the teeth and then moved forward to
prick the holes and afterwards moved backward out of the holes to their original
position. Two or more teeth are simultaneously inserted by a forward motion of the
nippers tongs or dies when they are held by them or when they have been otherwise
fed to the foundation material, by a similar motion of fingers plates dies or by
analogous means. If the teeth have subsequently to be bent or straightened or
otherwise set the points of the teeth on passing through the foundation material may
he received within hooks or eyelets attached to wires or arms fixed to a bar or plate
through which motion may be given to the hooks or eyelets. The bending of the teeth
is required when their points have to lie at less than a right angle to the foundation
when viewed from the edge and the straightening motion to bring the limbs of the
teeth to right angles to the foundation when viewed from the end. The bending is
accomplished by giving the hooks or eyelets a downward and if desired outward motion
and the straightening motion by closing each pair of hooks or eyelets towards each
other. The bending and straightening motions may be combined and their amount
may be governed or adjusted by causing the wires or arms to which the hooks or
eyelets are attached to pass in pairs through suitably formed holes in an adjustable
bar and by altering or adjusting their rectilinear motion. Each pair of wires or arms
carrying the hooks or eyelets tend to spring apart, hence the nearer the perforated
plate is adjusted to the teeth as they are inserted the less will be the amount of the
closing motion. The foundation material may be held and fed by means of
intermittently rotating rollers or by gripping devices so constructed arranged and
operated as to feed the foundation material to the required distance between the periods
of insertion of the teeth. The feed motion of the foundation material may require to
be horizontal vertical or diagonal. The horizontál motion may be obtained by moving
the rollers or gripping devices horizontally without rotation or independent rectilinear
motion and the vertical feed may be obtained by rotary or rectilinear motion and the
diagonal feed may be obtained by a combination or succession of the horizontal and
vertical motions.
The intermittent or irregular motions of the various parts may be obtained by means
of suitable cams tappets single or compound levers armis or links lobed or irregularly
shaped wheels or by other suitable means.

I, CHARLES MOSELEY of the Chapel Field Works, Manchester in the County of
Lancaster, Manufacturer 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 Cards such as are employed in the
treatment of fibrous materials and has for its object to expedite the said manufacture
and consequently lessen the cost of production. With this object the machinery
apparatus or means employed in the manufacture of the cards, is so arranged that two
or more teeth are simultaneously shaped or formed and afterwards simultaneously
inserted into the material which forms the foundation. For this purpose the machine
is according to my Invention arranged or constructed so as to grip and intermittently
feed the wires from which the teeth are to be made, to cut the wires to lengths
required for the formation of the teeth, to bend or form the said lengths
to the shape or approximately to the shape required for their insertion into the
foundation material to convey the teeth to the position for insertion in the foundation
and if required to pierce the foundation with holes for the said insertion and to
insert simultaneously two or more teeth into the foundation, the foundation being held
stationary during the said insertion and between the periods of such insertion of the
teeth, a lincar transverse or diagonal motion being imparted to the foundation to bring
it into the required position. Means are also provided for giving the teeth the
necessary amount of inclination when they are required to be bent after the insertion
into the foundation material.
The Invention is not limited to any one precise mechanical arrangement of details,
nor to the performance of the operations in the order or sequence hereinbefore
mentioned, and if desired some of the operations may be performed by mechanism
independent of that which performs other of the operations.
I will describe generally the nature of arrangements by which the Invention may
be effected.
The wires from which the teeth are to be made are fed by suitable clutching or
gripping devices having intermittent motion and so combined or arranged and
actuated that the clutches or grippers seize the wires and convey or feed them in one
direction only, other clutches or grippers hold them stationary on the return stroke
whilst the first named clutches or grippers are released and return to their original
position. The motion of the feeding device is so governed or controlled that the length

page_text: of the wires fed is in accordance with the length required to form the teeth. The
wires are seized and held by tongs nippers dies or their equivalent at the central parts
and are then cut to the lengths required.
The lengths of wires are most conveniently bent while still held by the tongs
nippers or dies by turning or bending both the ends projecting from the jaws or dies
at right angles to the part held. The teeth so formed are conveyed to the foundation
material in correct position for insertion in such a manner that the points of the teeth
arrive in their proper positions relatively to the foundation material through which
they are to be inserted or fixed. If holes are required to be pricked through the
foundation material for the insertion of the teeth, this may be done by prickers
mounted at the desired distances and relative positions and brought at the requisite
times to the plane to be occupied by the teeth and then moved forward to prick the
holes and afterwards moved back out of the holes to their original position. Two or
more teeth are simultaneously inserted by a forward motion of the nippers tongs or
dies when they are held by them or when they have been otherwise fed to the
foundation material by a similar motion of fingers, plates, dies, or by analogous
means.
If the teeth have subsequently to be bent or straightened or otherwise set this may
be effected by causing the points of the teeth on passing through the foundation
material to be received within hooks or dies to which motion may be given for acting
on the wires to bend them to the desired angle in one direction, or to bring them to
their true vertical or other desired position in the other direction. The bending and
straightening motions may be combined and governed or adjusted by causing devices
to which the hooks or dies are attached to pass in pairs through suitably formed holes
in an adjustable bar and by altering or adjusting their rectilinear motion. The
foundation material may be held and fed by means of intermittently rotating rollers
or by gripping devices so constructed arranged and operated as to feed the foundation
material to the required distance between the periods of insertion of the teeth.
The feed motion of the foundation material may require to be horizontal vertical or
diagonal. If horizontal motion of the foundation be necessary for any given arrangement
of teeth it may be obtained at the requisite intervals by moving the rollers or gripping
devices horizontally the vertical feed may be obtained by rotary or rectilinear motion and
the diagonal feed by a combination or succession of the horizontal and vertical motions.
The intermittent or irregular motions of the various parts may be obtained by
means of suitable cams tappets single or compound levers arms or links lobed or
irregularly shaped wheels or by other suitable means.
I will describe my Invention with reference to the accompanying drawings
illustrating a machine for simultaneously forming and subsequently simultaneously
inserting seven teeth but it is to be understood that my Invention is not limited to
that or any particular number more than one.
In the various Figures on the accompanying drawings similar parts where they
occur are indicated by similar numbers of reference.

The wires 1 on their way from the recls (or other containers of the supply of wires)

page_text: to the apparatus pass first through holes in the cross bar 2 which is fixed upon the
pillars 3 and the said wires thence pass to the feed slide 4 and to the gripper 5 details
of which are shown in Figures 6 and 7. The gripper is stationary but the feed slide
has an up and down motion. The wires 1 are alternately gripped by the feed slide
and by the gripper in the following manner. During the down stroke of the feed
slide each wire is gripped between the front and back plates and at the same time the
gripper 5 is open so that the wires may press freely through it. At the end of the
down stroke of the feed slide 4 the front and back plates therein are separated and
the wire ceases to be held by the feed slide, at the same instant or a little earlier the
gripper 5 seizes the wires and holds them in the advanced position while the feed
slide returns to the beginning of its stroke. It follows from this that for each cycle
of motions any desired length of the wires may be fed to the apparatus and be held
stationary for a subsequent operation. The length of the feed must correspond to the
total length of wire required to form one tooth. The up and down motion of the feed
slide and the wire gripping devices in the feed slide 4 and the gripper 5 are obtained
from the cam 6 and the cam 10 on the vertical shaft 7 (Figures 1 and 4) which
receives its motion through the two pairs of mitre wheels 8.
The cam. 6 originates two distinct motions the first by the irregular horizontal
section shewn in Figure 4 and the second by the double inclined plane 9. In
Figure 1 one incline only is shewn the other being on the opposite side of the cam.
The cam 10 originates a motion similar to that of the lower part of the cam 6 but is
timed to operate at intermediate periods. The cam 6 actuates the bar 11 which has
two inclined plans 12 13 (figure 4) the cam 10 actuates the similar bar 14 having
inclined planes 15 16 (Figure 3). The inclined parts 9 of the cain 6 actuate the
arm 17 (figures 1 and 3) attached to the rod 18 which is fixed to the feed slide 4
originating a vertical reciprocating motion. The inclined faces of the bars 11, 14
work upon fixed surfaces attached respectively to the feed slide and to the gripper,
and their motions produce the herein before described alternate gripping action upon
the wires by the movement of the inclined planes 12 and 13 on bar 11 and 15
and 16 on bar 14. The return vertical motion of the feed slide is produced by the
spring 19. The return horizontal motions 11 and 14 are secured by the springs 20.
and 21.
the
In order to prevent the possibility of any particular wire not being gripped by the
feed slide or stationary gripper which would be likely to occur if they were attempted
to be held between rigid surfaces, a separate block and spring is arranged for each
wire in each of the gripping motions 4 and 5. These are shewn in figure 6 and 7.
where the independent block and spring for each wire is indicated at 22
springs and plates are also indicated in the front elevation figure 1. The length of the
stroke of the feed slide and consequently the length of wire fed at each stroke is
controlled by means of the nut 23 which may be adjusted through a hole in the bar 2
by rotating it upon a thread formed on the upper part of the pillar 24 included within
the nut. To the bar 18 is attached an arm carrying the sleeve 25 which slides with 18
up and down the pillar 24.
If then the nut 23 is screwed downward upon the pillar 24 the sleeve will come in
contact with it and thus arrest the upward motion of the feed slide earlier and secure a
shorter stroke for the feed motion while if it is screwed upwards the reverse will
occur and thus the length of the feed may be varied within considerable limits.
The wires are fed forward through the dies 26 in the bar 27 and at the end of each
stroke of the feed motion, lengths of wire, cach corresponding to the total length of
one tooth should project beyond the under surface of the dies as shewn in Figure 7.
Below and to the rear of the feeding devices are arranged as many parallel slotted
tubes 28 as there are teeth to be formed and inserted at one operation. As illustrated
in the drawings the apparatus is arranged for the formation and insertion of seven
teeth, this being a convenient number. Within the tubes are reciprocating rods or
rams 29, Figures 6, 7, 8, 9, 10, 11, 12. The front edges of the tubes have V shaped
recesses 30, see Figure S. The tubes are supported in a bearing the cover or

page_text: removable upper portion of which is indicated at 31. Through this cover are inserted
pins in such a manner that one pin enters the slot 32 of each tube. This slot is so
formed that when the tube is pushed forward the pin working in the slot allows each
tube to advance for a short distance without rotation, then causes the tube to turn
through a quarter revolution and finally allows it to continue its motion to the end of
the stroke without turning, and at an angle of 90 degrees to the position of the tube
at the commencement of its motion. In front of and below the tubes are two vertical
pins 33 carrying the rising bar 34, these pins have a vertical reciprocating motion
within the. tubes 35.
Above the cover 31 are the knives or cutters 36 which at the proper time advance
and cut off the wires close below the dies 26.
The motion of the parallel slotted tubes is obtained from the tappet 37, Figures 10
and 11 and is conveyed therefrom by the sleeve 38 working on the rod 39. The
sleeve carries a bracket to which are connected the bars 40 the upper one of which
is provided with one nib or projection for each tube fitting into a quadrant slot 41 in
the tube (figure 6). By this means the forward and backward motions of the tubes
are secured while at the same time their rotary motion is provided for. The tappet
is shaped as shewn in the drawing so as to provide for the motions and periods of
repose hereinafter described.
The motion of the rams or pistons in the slotted tubes is obtained from the
tappet 42. Figures 10 and 11 which actuates the sleeve 43 to a bracket upon which
is pinned the forked connecting rod 44 which carries the bearing bar 45 through a
slot in which the ends of the rams pass. The rods have heads formed upon them at
the back of the bearing bar 45 against which abut the springs 46 which are secured to
the rail 44. These springs are provided one for each wire in order to allow for any
possible variation in the diameters of the wires from which the teeth have to be
formed and to prevent a dead blow upon them. The tappets 37 and 42 may be
enclosed so as to give a positive motion in each direction or they may be open tappets
as shown in the drawings in which case the return motions of the tubes and rams is
secured by springs indicated at 47.
The vertical reciprocating motion of the bar 34 is derived from inclined plains on
the bars 48. Figures 6 and 7 which are attached by studs 51 to the lever 52 which
also actuates the pricking motion to be hereinafter described. The lever 52 is centred at
49 to the swinging lever 50 and is operated by the cam 53 The motion of the
lever 52 may be regulated by the adjusting strip and set screw 54 The inclined
surfaces on 48 in passing forward through slots in the tubes 35 raise the pins 33 and
consequently the bar 34 while in their backward motion the bar and pins are forced
downwards by the springs 55.
The cutting motion is shown in Figures 35 and 6. The knife 36 is fixed to a rocking
bar 56 which is actuated by the cam 57 Figure 3 and the rod 58 return motion is
secured by the spring 59.
The strip of cloth leather card or other foundation or backing into which the teeth
have to be inserted is omitted from Figure in order to enable the mechanisin of the
apparatus to be represented, its position relatively to the teeth forming and inserting
motions is shown in Figure 8 at 60 it is also shewn in Figures 13 and 15. Before the
teeth are inserted it is usually necessary to prick holes in the fabric for their passage.
The pricking motion is shewn in Figures 3. 6. 8 and 13 and is actuated from the
lever 52 which carries at its end the pricker head 61 to the front of which the pricking
points are secured.
The teeth after they are formed are guided into their proper position and held while
they are being bent by the guide motion Figures 3. 18 and 14. This consists of two
plates 62 and 63 which are mounted in slots in two end plates and are drilled with
slightly conical holes at their line of junction as many holes being made as there are
points of teeth to be inserted (which in the present example is fourteen) and their
position being coincident with that of the pricking points when pricking the foundation.
While the holes are being pricked by the pricker these plates are separated as shewn

page_text: in Figure 13 for the passage of the pricker head 61. This separation is effected by a
wedge motion as indicated in Figure 14 there being one wedge 64 at each end of the
guide plates. The motion of the wedges is obtained from the cam 65 Figure 3 which
operates the rod 66 to the opposite end of which the wedge motion is pinned, the
wedges are fixed upon the rocking shaft 67 which is also partly shown in Figure 1.
The plates are forced together again by the springs 70.
The apparatus for bending the teeth after insertion is shewn in Figures 15. 16 and
17. The teeth after passing through the cloth are caught by the hooks 68. Below the
teeth and in contact therewith is a template 69 over which the teeth are bent and
the thickness of which is varied according to the desired position of the crank or bend
of the teeth. When the teeth are engaged by the hooks the latter descend and recede
from the cloth. The hooks are alternately mounted upon two bars 71 72 which are
carried on the arms 73 fixed upon the shaft 74 the position of which may be regulated
as desired in the slot 75 in a fixing cast upon or fixed to the machine side. The motion
of the shaft 74 is obtained from the tappet 76 Figure 3 through a connecting rod 77
to the lever 78 upon which the rocking shaft 74 is fixed. The two bars 71 and 72
upon which the looks are alternately fixed have reciprocal motion relatively to each
be caused
other so that each pair of hooks engaging the two points of one tooth may
to approach and thus tend to close up the points of the teeth as is done in ordinary
card making machines. The motion of these bars is obtained by forming one end of
each bar to an inclined plane and placing the inclined ends at opposite extremities of
the motion. One of the inclined ends is shewn in Figures 16 and 17. Against each
inclined end abuts an adjustable point 79 fixed upon a bracket. When the bars are
operated by the arm 73 their inclined ends work against the adjustable points and the
bars consequently receive rectilinear motions in opposite directions. The bars are
restored to their original positions by the action of springs 80.
The cloth is or may be held, fed, and moved transversely and vertically by means of
apparatus similar to that employed in existing machines.. The modifications which are
rendered necessary, by the fact that by the present invention two or more teeth are
simultaneously inserted instead of one, are indicated in Figure 18 and consist of a cam
which must be specially formed and constructed according to the character of the card
to be produced. Thus in the manufacture of ordinary filleting the working edge of
the cam would have three falling steps and a corresponding three step rise to the
original level as indicated at 81 (figure 18) instead of the usual construction. This
cam is placed in a similar position and is actuated by similar means to the equivalent
cloth motion cam in ordinary machines.
The driving motions are or may be (otherwise than as hereinbefore described) similar
to those employed in existing machines and are herein simply enumerated and
identified on the drawings by numbers. They consist of 82 the hand wheel; 83 pulley
for driving by power; S4 the gearing ordinarily employed when blank spaces are
required in the fillet; 85 the cloth feed ratchet wheel; 86 the cloth grip rollers;
87 bar carrying the roller bracket.
The progress of the wires as far as the dies 26 has already been described, the
position of the projecting ends of wire is then as shewn at 1 in Figure 7. The bar 34
is then lifted to the level of the slots. 88. In the front ends of the tubes 28; the said
tubes then move forward a short distance and in doing so the wires are guided by
the V (30) therein to the exact positions required. Simultaneously the rams 29 are
advanced so that the wires are gripped or seized hetween the front ends of the rams
and the edge of the plate 34. The cutters or knives 36 then advance and sever the
wires immediately below the dies 26 while the tubes 28 are pushed forward and the
wires are lient into the tube during the forward motion by the bar 34 entering
the grooves 88 the bending operation being shown half completed on Figure 10. The
outward spring of the legs of the teeth so formed causes them to remain in the tubes
when the tubes and rains are withdrawn from the bar 34.
Upon the retreat of the tubes the bar 34 is released and by the action of the
spring 55 and the bar 48 it falls to its original position leaving an open path for the

page_text: further forward motion of the tubes 28 containing the formed teeth. During the forma-
tion of the teeth as described the pricker advances and pricks the cloth then returns
to its first position, while during the pricking motion the plates 62 and 63 separate to
permit passage of the pricker head as shewn in Figure 14. The said plates 62 and 63
close up again as soon as the pricker is withdrawn. The tubes 28 and rams 29 now
advance together and during their travel the tubes make a quarter rotation being
compelled to do so by the spiral part of the slots 32 in which the fixed pins engage as
hereinbefore described This quarter rotation brings the teeth into the horizontal
position required for insertion in the foundation (as shown in sectional elevation
Figure 8 and in plan Figure 9). The ends of the tubes having arrived in contact
with the guide plates 62 and 63, which are now closed together, the rams are pushed
forward forcing the points of the teeth through the holes between the guide plates and
into the foundation material. During this process the hooks 68 are brought into
position to receive the points of the teeth as they issue through the foundation material
as shewn in Figure 15 The hooks then as already described bend the wires over the
template 69 and close the points together and at the same time the tubes 28 and
rams 29 return to their first position and the plates 62, 63 are separated so that the
staples may be driven home by the upper part of the pricker head 61 in the operation
of making the next series of holes. The foundation material is now advanced or fed
the requisite distance and direction which may be effected in the usual way by weights
and the gripping rollers and a cam 81 (Figure 18) to the required position for the
insertion of the following teeth completing the cycle of motions the operations already
described being repeated and so on during the action of the machine.
Having now described the best means with which I am acquainted of carrying my
invention into effect I would observe that I do not limit myself to the precise means
.described and illustrated of obtaining the motions to effect the various operations
necessary to cut the wires, form them into teeth and insert and bend them as it will be
evident that many mechanical equivalents for the means of operation which 1 have
described may be used, nor do I limit myself necessarily to the precise order of the
operations described the essential feature of my Invention being the manufacture of
cards and the provision of means apparatus or machinery to be used in the said
manufacture by the formation and subsequent insertion of two or more teeth
simultaneously as distinguished from the method and means at present practiced of
inserting one of the teeth at each operation of the machine. By one tooth I mean one
piece of wire bent into a two pronged form.
What I consider to be novel and original and therefore claim is.

materials, by the formation simultaneously of two or more teeth and their subsequent
simultaneous insertion into the foundation material.
