Improvements in Machine Tools for Applying "Fasteners" used for
Securing Card Clothing to the Bars or Flats of Flat Carding
Engines.
We, FREDERICK WHITLEY THOMSON, of Brunswick Mills, Halifax, in the
County of York, Card Maker, and JAMES HAIGH, Mechanic, of Brunswick Mills,
aforesaid, do hereby declare the nature of our said invention to be as follows:-
This invention relates to new and improved machine tools for the purpose of
securing card clothing to the bars of carding engine flats, by means of fastening
devices, such as are described and illustrated in Specification of Letters Patent
granted to Nathan Whitley, Frederick Whitley Thomson and Henry Hoyle,
bearing date the 27th day of March 1885, and numbered 3901, the improved
machine being so constructed as to grip and firmly hold the bar, or flat, whilst a
carrier or clip and presser descends, and forces the points and protruding parts or
tongues of the strip through the foundation fabric the latter being if necessary
punctured for facilitating entrance of the points and through the holes which are
bored near the edges of the bar or through nicks or saw gates cut in the edges of
the bar to be covered until the head or strip proper is pressed tightly down to and
upon the foundation fabric the said strip and prongs are so held by the presser
whilst a roller moves along and underneath the length of the bar and turns down
and clenches the protruding part and points of the tongues to the underside of the
bar, meanwhile the clothing having been under tension laterally and longitudinally
is when so fixed held evenly and securely in position along the bar without creases
or puckers.
The above object we effect by means of a carrying frame and a pair of nipping
jaws consisting of two plates of metal their distance apart being adjustable by
means of threaded or screwed shafts which pass through them, the said shafts
(preferably two) having at one of their enls bevel wheels gearing with bevel wheels
on a shaft extending across the front of the machine and provided with a hand
wheel for turning same.
The nipping jaws receive and tightly grip, when screwed up, the flat to be
covered. The flat is held face upwards between the jaws and flush with the face of
same which formn a small table the card clothing is placed on the face of the flat and
a hinged guide, or straight edge is turned with its face against the teeth or dents of
the card clothing and thereby ensures the latter being placed in correct position on
the face of the flat and in relation to its edge. One end of the foundation fabric is
gripped and held by a jaw at that end of the flat, and the other end of the foundation
fabric has attached to it a hook and cord, or strap and weight so that the foundation
is stretched longitudinally.
The clothing is stretched laterally after one side or edge thereof has been secured
to the bar by a fastening strip or device as above referred to, by means of a flat
bar of metal carried on the table, level with the nipping jaws and on the bar of
metal there is hinged a serrated jaw, which projects slightly beyond the metal bar,
the serrations being forced into the edge of the clothing and held there by lever, or
otherwise, and the bar of metal and serrated jaws are moved in a parallel direction
away from the secured edge of the clothing by screwed shafts, bevel wheels, and
hand wheel or other equivalent devices so that the clothing is effectually stretched,
and the over hanging serrated jaw enables the clothing to be held much nearer to
the teeth or dents and thus there is less waste, or the lateral stretching may be
effected by means of clamps or other equivalent devices.
Above the nipping jaws and carried in the end frames of the machine is a
turntable, one edge of which forms a carrier, and presser, the clip consisting of a

page_text: central bar of metal which is also the presser, and is of taper section and on one,
the flat side, is mounted a thin strip of metal extending the length of the presser,
on the other and angled side is mounted a second strip of metal, these two strips,
and the intervening bar of metal form the strip carrier. A bar of metal having in
one of its faces small saw gates or nicks at such a distance apart as the pitch of the
holes in the flat, and of the tongues or pins of the strip, is mounted on, spring
hinges on the turntable. When the strips are inserted in the clip holder the har of
metal on the flat side of the presser serves as a guide for the tongues or pins of the
strip and that on the angled side as a holder for the head of the strip, the bar of
metal with the saw gates in its edge is forced down on its hinges until it comes in
contact with the strip of metal on the flat side of the presser, and the points of the
tongues or pins protrude one through each of the saw gates or nicks the turntable,
clip, and presser are now turned over by a hand lever until the strip of metal on
the flat side of the presser comes in contact with the teeth or dents of the
clothing.
The turntable being hinged, at both ends, and carried in vertical slots in the end
frames has, when in operation a rising and falling motion imparted to it by means
of links, and straps eccentrics the latter operated by a cross or eccentric shaft,
which is arranged so as to have when in operation intermittent motion, of say half
or quarter of a revolution at one time.
At the back of the machine is a tappet shaft on which are two tappets operating
on two fingers which come in contact with two triggers or studs attached to the
spring hinges of the bar of metal having the face with saw gates above referred to.
The two strips of metal on the presser are attached thereto by pins or set screws
which pass through slots in them.
The action is as follows:-
When the turntable presser, and clips are turned by hand lever until the points
of the tongues, or pins rest on the surface and near the edges of the foundation
fabric on the flat, the attendant by lever or treadle and gear gives a half turn to
the eccentric shaft which by its connecting links forces down the presser on the
head or strip of the fastener and the pins or tongues thereof are forced through the
foundation fabric and the holes or nicks in the bars at the same time that the half
revolution is given to the eccentric shaft the tappet shaft is caused to make one or
more revolutions and the action of the tappets on the fingers is to press the latter
on the triggers or studs of the spring hinges, releasing the latter and causing the
bar of metal with the saw gates to move clear of the presser allowing the latter to
press the tongues or pins, and the head, or strip well home.
The presser remains on the head or strip whilst carriage and lever having a
counterbalance weight at one end, and a roller or runner at its other is traversed
along a threaded shaft or guide underneath the nipping jaws, the roller or runner,
pressing on the points of the tongues or pins and folding and clenching them tightly
as described on the underside of the flat; whereon on the attendant depressing the
treadle or lever another half revolution of the eccentric shaft raises the presser, and
clips, and the turntable is turned on its hinge ready to receive strips for a second
operation.

Improvements in Machine Tools for Applying "Fasteners" used for 5
Securing Card Clothing to the Bars or Flats of Flat Carding
Engines.
We, FREDERICK WHITLEY THOMSON, of Brunswick Mills, Halifax, in the
County of York, Card Maker, and JAMES HAIGH, Mechanic, of Brunswick Mills
aforesaid, do hereby declare the nature of this invention, and in what manner the 5

page_text: same is to be performed, to be particularly described and ascertained in and by the
following statement:-
This invention relates to new and improved machine tools for the purpose of
securing card clothing to the bars of carding engine flats by means of fastening
devices such as are described and illustrated in Specification of Letters Patent
granted to Nathan Whitley Frederick Whitley Thomson and Henry Hoyle
bearing date the 27th day of March 1885 and numbered 3901 the improved
machine being so constructed as to grip and firmly hold the bar, or flat, whilst
a carrier or clip and presser descends and forces the points and protruding parts
or tongues of the strip through the foundation fabric (the latter being if necessary
punctured for facilitating entrance of the points) and through the holes which
are bored near the edges of the bar or through nicks or saw gates cut in the
edges of the bar until the head or strip proper is pressed tightly down to and
upon the foundation fabric, the said strip and prongs being held by the presser
whilst a roller moves along and underneath the length of the bar or flat and
turns down and clenches the protruding part, and points of the tongues, to the
underside of the bar; meanwhile the clothing having been under tension, laterally
and longitudinally, is when so fixed held evenly and securely, in position along
the bar and without creases or puckers.
The above object we effect by means of a carrying frame, and a pair of
nipping jaws, consisting of two plates of metal, their distance apart being adjust-
able by means of threaded or screwed shafts, which pass through them, the
shafts (preferably two) having at one of their ends bevel wheels gearing, with
bevel wheels on a shaft extending across the front of the machine, and provided
with a hand wheel or lever for turning same.
The nipping jaws receive and tightly grip, when screwed up, the flats to be
covered. The flat is held face upwards, between the jaws, and flush with the face
of same, the jaws forming a small table, the card clothing being placed on the
face of the flat, and a hinged guide, or straight edge is turned with its edge
or face against the teeth or dents of the card clothing thereby ensuring the latter
being placed in correct position on the face of the flat and in relation to its
edge. One end of the foundation fabric is gripped and held by a jaw at or
near that end of the flat, and the other end of the foundation fabric, has attached
to it a hook and cord, or strap, and weight, so that the foundation is stretched
longitudinally. The clothing is stretched laterally, or across its width, after one
side or edge thereof has been secured to the bar, by a fastening strap or device,
as above referred to, by means of a flat bar of metal, carried on the table level
with the nipping jaws, and on the bar of metal there is hinged a serrated jaw,
which projects slightly beyond the metal bar, the serrations being forced into
the edge of the clothing and held there by lever or otherwise, and the bar of
metal and serrated jaws, are moved in a parallel direction, away from the secured
edge of the clothing, by screwed shafts level wheels, hand lever, and tappets,
or other equivalent devices so that the clothing is effectually stretched and the
overhanging serrated jaw enables the clothing to be held much nearer to the teeth
or dents and thus there is less waste; or the lateral stretching may be effected by
means of clamps or other equivalent devices.
Above the nipping jaws, and carried in the end frames of the machine is a
turntable, one end of which forms a carrier and presser consisting of a central
bar of metal which is also the presser, the latter is of taper section, and on one,
the flat side, is mounted a thin strip or bar of metal, extending the length of
the presser, and on the other and angled side is mounted a second strip or bar
of metal.
These two strips or bars and the intervening bar of metal, form the strip
carrier, the bar of metal on the angled side has in one of its faces small saw
gates or nicks, at such a distance apart as the pitch of the holes, in the flat,
and of the tongues, or pins, of the strip.

page_text: When a strip is inserted in the strip holder, the bar of metal on the fat side
of the presser, serves as a guide for the tongues, or pius. of the strip, and that
on the angled side, as a holder for the head of the strip, and also as a support
to the pins or tongues the points of the latter protruding one through each of
the saw gates or nicks; the turmable, clip and presser are now turned over by
a hand lever, until the strip of metal on the flat side of the presser, comes in
contact with the teeth or dents of the clothing.
The turntable being hinged, at both ends, and carried in vertical slots in the
end frames, has, when in operation, a rising and falling motion imparted to it
by means of links, and strap eccentrics the latter operated by a cross or eccentric
shaft, which is arranged so as to have when in operation intermittent motion, of
say one or a half or quarter of a revolution at one time as may be desired.
Such being the nature and object of our said invention the following is a
complete description of same reference being made to the accompanying drawings

Fig. is a view of the under-edge of the presser turntable and carrier.
Figs. 6. 7, and 7 are details of the clenching apparatus -Fig. 7 being a modifica-
tion of Fig. 74.
Fig. 6 is a detail shewing the clothing in the correct position on the flat, and
rundy for one edge being attached thereto.
According to this our said invention at 1. 1. is a carrying frame in which is
supported a holding device for the bar or flat 2, to be covered, and this holding
device consists of two pieces, or "heas" of metal 3. 3, their distance apart being
adjustable by means of threaded or screwed shafts 4. 4. which pass through
them, the said shafts 4. 4. (preferably two) having at one of their ends bevel
wheels 5. 5. gearing with level wheels 6. 6. on a shaft 7. extending across the
front of the machine, and provided with a hand wheel, or lever 8 for operating
saine.
The nipping jaws 9. 9. of the two beds 3. 3. receive, (and when the lafter are
moved together, by means of the hand lover or wheel 8) tightly grip the flat or
bar 2 to be covered the said flat or bar being held face upwards (see Figs. 4 and 6A)
between the jaws 9. 9. and flush with the face of same the upper surfaces of "the"
beds 3. 3. forming a small table. The card clothing 10 is now placed on the flat 2
and the hinged guide, or straight edge 11 is turned with its straight edge or face
ngainst the teeth or dents of the card clothing 10 (see Fig. 6) and thereby ensures
the latter being placed in correct position on the face of the flat 2. and in relation
to the edge of the latter. One end of the foundation fabric of the card clothing 10.
is gripped and held by the jaws or clamp 12. fixed to the table at or near the end
of the flat 2 and the other and opposite end of the foundation fabric has attached to
it by hook or otherwise a cord or strap and weight 13 by means of which the
foundation of the card clothing is stretched longitudinally.
The card clothing 10 is stretched laterally or across its width after one side or
edge thereof has been secured to the bar or flat 2 by one of the strips or devices,
as shewn and described in the Specification of Patent No. 3901 aforesaid. This
stretching we accomplish by means of a fat bar or strip of metal 14 enrried on one
of the beds 3 and level or flush with the nipping jaws 9. 9. and on this bar of
metal 14 is hinged a serrated jaw 15 the serrated edge of which projects slightly

page_text: beyond the lower metal bar 14 and the jaw 15 being moved by the attendant over the
edge of the foundation fabric 10 the serrations are forced with the latter tightly
gripping, and holding sanie, by means of the lever 16, slightly turning the jaw 15 on
its hinges. The bar of metal 14 and jaw 15 nipping and holding the edge of the
foundation 10 are now moved in a parallel direction away from the secured edge of
the clothing by turning the hand lever 17 which gives a part revolution or turn to
the shaft 18 on which are tappets 19 the latter operating on the cranked arms 20
hinged at their lower ends to the beds 3. 3. and their upper ends carrying the bar
of metal 14 and jaw 15 so that by moving the hand lever 17 the foundation 10 is
stretched Interally or across its width and when sufficient tension is put upon the
clothing the hand lover 17 is held in the required position by a catch or pawl,
mounted on same, engaging with the rack 21 contiguous to it, so that the clothing
is effectually stretched both laterally or across its width and longitudinally or
lengthwise the overhanging serrated jaw 15 allowing of the clothing 10 being held
much nearer the teeth or dents and thus there is little or no waste of material.
Above the nipping jaws 9. 9. and carried in the end frames 1. 1. is a turntable 22
one (the lower) edge of which forms a carrier and presser consisting of the central
bar which is the edge of the turntable 22 the latter being of taper section (see Fig. 3)
and on one, the flat side 23 is mounted a thin bar of metal 24 extending the length
of the presser 22 and attached thereto by screws or studs passing through slots in
the strip 24 and the latter is forced downwards by spiral springs 25 there being one
or more of such springs near each end of the turntable 22. On the opposite and
angled side 26 of the turntable 22 is carried a second bar of metal 27 which can be
moved up or down by the handles 28 and the lower edge of the bar 27 is slightly
curved or bent and has nicks recesses or
sawgates "29 formed in it for purpose
hereafter described. The two bars 24. 27 and the intervening har of metal or
presser 22 form the strip carrier, the strip or bar of metal 27. having the sawgates or
nicks 29 formed in it. The latter being at such distance apart as the pitch of the
holes or sawgates in the edge of the flat 2 and of the tongues or prongs 30, of the
strip and when a strip is inserted into the strip holder the bar of metal 24 serves as
a guide for the tongues or prongs 30 of the strip and the bar 27 holds the head of
the strip, in position close to and against the presser 22 and each tongue or prong 30
of the strip protrudes through one of the nicks or sawgates 29 in the bar 27.
The turntable 22. is by hand lever 31. turned over on its axis 32. and held in a
convenient position, for facilitating the insertion of the strip into the holder by the
catch 33 dropping or being forced into one of the holding notches 34 in the disc 35
and when the strip is inserted into the holder the catch 33 is withdrawn by the
attendant from the notch 34 and the turntable 22 presser and strip are turned over
by the hand lever 31 until the strip of metal 24 comes in contact with the teeth or
dents of the clothing 10 (see Figs. 3, 4, and 6).
The axis 32 of the turntable 22 is carried at each end in the bearings or collars 36,
connected by adjustable screwed links 38 to the strap eccentrics 37 and the axis 32
is prevented from moving laterally by being carried in vertical slots in the end
frames 1. 1. the eccentrics 37 on the main shaft 39 when the machine is in operation,
imparting a rising and falling motion to the turntable 22 and appliances connected
thereto.
Carried in the bed 3 beneath the jaws 9. 9. is the slide 40 (see Fig. 4) which is
traversed from one end, to the other of the beds 3. 3. by means of the screwed shaft 41
driven by pulley 42 and as the slide 40 travels along the under side of the flat or
bar 2 the runners or rollers 43 carried in the recess 44 in the upper end of the
arm 45 (see Figs. 7 and 7^) press upon, bend and clench all the tongues or prongs 30
of the strip whilst the top of the latter is under pressure from the presser 22 and
when the slide 30 has travelled to one end of the flat it is by the attendant moved
out of gear and by raising the handle 46 the runners 43 are moved away from the
underside of the flat, 2, the handle resting on the longitudinal bar 47 which is held
in contact with it by the pins 48 being received in the hook 49.

page_text: The slide 40 is caused to traverse from end to end of the beds 3. 3. in the ordinary
manner the shaft 41 being put in or out of gear with the driving wheel 42 by means
of the clutch and gear arrangement 59 operated by the rod 60 on which is the
handle 61. which when moved to the right or left by the attendant places the clutch
in gear with one of the bevel wheels 59 at the same time carrying with it the inclined
surfaces 62, 62, which latter move the hooks 40, 49, on their fulcrums or hinges and
away from the pins 48, 48 and the latter with the longitudinal bar 47 will fall
allowing the handle 46 also to fall and consequently its end 63 will rise and move the
arm 45 carrying the runners 43 close to the underside of the flat 2 (see Figs. 4 and 6)
and the pressure of the spring 64 will effectually elench the tongues or prongs 30 as
above described, and when the slide 10 has traversed the length of the flat 2 the
handle 46 is again raised, lowering the runners 43, the handle 46 being maintained
in the raised position by the bar 47 the latter being also raised and the pins 48
received in the hooks 49.
The middle one of the 3 eccentrics 37 has a short Ing or pin formed on it which is
received on a bracket or step fixed to the upper edge of the turntable 22 and this
eccentric assists in foreing down the turntable and presser 22 though it takes no part
in the raising of same as it is not attached to it.
At 30 is the main driving pulley which has a clutch arrangement whereby the said
pulley may be made fast or loose on its shaft 51. and this pulley 50, as also the
pulley 42, are driven by belts or strap from any convenient source.
The operation of applying the strips, and action of the machine is as follows:-
The strip is placed in its holder after turning the turntable 22 over on its axis 32
the bar of metal 27 is by the handles 28 moved towards the axis 32 and the strip is
then in the position shewn by Fig. 3. after which the bar 27, is forced downwards or
away from the axis 32 so that the strip is held (as shewn by detail Fig. 3) the
points of the tongues or prongs 30 just protruding beyond the two bars of
metal 24, 27 the bar 27 being pressed nearer to the bar 24 by the eccentric shaft 32
being turned by the handle 33 the two bars and the presser 22 thus hold, and serve
to support or strengthen the tongues or prongs 30 when the latter are being forced
through the clothing 10.
The flat 2 and the strip being placed in and held between the jaws 9. 9 the
turntable 22 is turned over to the position shewn in Fig. 3. (the strip being in the
position shewn by Fig. 34) the bar 24 coming in contact with the teeth or dents of
the clothing 10 the latter being adjusted and held in correct position by the hinged
bar of metal 1 (see Fig. 6A) the catch 33 is placed in the holding notch 34 then by
the attendant raising the hand lever 54 and thus turning the shaft 55 the latter by
its commeeting links 36 locks the wheel 50 to its shaft 51 and the latter is caused to
make one revolution or part of a revolution as may be required when the clutch of
the wheel 50 is again automatically moved out of gear, or made loose on its shaft by
any of the well known arrangements for such purpose. The whole or part revolution
given to the shaft 51. imparts by the wheels 57, 58 motion to the shaft 39, and the
latter by the eccentries 37, 37 and links 38 forces down the turntable 22 until the
lower edge or presser of the latter forces the points of the tongues or prongs 30 of
the strip through the foundation 10 and through the holes or saw gates in the
flat 2 the pressure of the turntable being suflicient to force the tongues or prongs 30
through the foundation 10 and through the holes or saw gates in the flat 2 that the
head of the strip presses lightly on and along and close to the edge of the foundation
(see Figs. 6 and 6) the bars of metal 24. 27. being moved towards the axis 32 by
coming in contact with the foundation 10 as the presser descends and being no longer
required to strengthen or support the tongues or prongs 30. The presser 22 remains
stationary on the head of the strip while the slide 40 travels along the underside of
the flat 2 clenching all the protruding ends of the tongues or prongs 30. (see Fig. 6)
tightly to aud against the underside of the said flat or bar 2 and when this operation
is completed another revolution or part revolution of the shaft 39 will raise the
presser and appliances connected therewith. The flat is now removed and reversed

page_text: and again placed in the machine for securing the clothing 10 to the other edge of
said bar or flat. 2.
The foundation is now stretched laterally or across its width in manner hereinbefore
described and secured by one of the said strips (see Figs. 4 and 6) applied by means
and in manner employed for securing the first edge.
Having now particularly described and ascertained the nature and object of our
said invention, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The general construction arrangement, and combination of parts constituting
the improved machine tool or appliance for purpose herein set forth, and as fully
described and illustrated by drawings annexed.
2. The appliances for holding supporting and guiding and for forcing down and
through the foundation the tongues or prongs of the holding strip together with the
roller or other such like device for clenching as herein fully described and illustrated
by the drawings annexed hereto.
