We JOSEPH LAW, Card Manufacturer JOHN WILLIAM FAWCETT Engineers
Fitter and ERNEST JONES Card Nailer all of Moorland Mills, Clookheaton in
the County of York do hereby declare the nature of this invention to be as
follows:-
:-
This invention relates to improvements in appliances for bending and shaping
strips of metal for securing said strips to the clothing or fillets previous to such
fillets being secured to the flats of flat carding engines in the manner described in
Specification of Letters Patent No. 21394 dated December 8th 1891 granted to
John William Fawcett and Ernest Jones. The object of this invention is-
First. To bend or shape the strip after the serrated edge and prongs or pins have
been formed thereon. Secondly. To fix such bent strips to the edges of the fillet
or card clothing.
According to this invention we mount on a table or gantry a pair of jaws one of
Buch jaws being fixed the other moveable by means of eccentrics or cams and levers.
The fixed jaw has a recess formed in it for the reception of the pins or prongs of
the strip and when the latter is placed in position between the jaws the latter are
closed by bringing the moveable jaw towards the fixed one. The moveable jaw
has its edge formed to correspond to the bend or shape desired to be given to the
strip, and the jaws and strip are now traversed along the table or gantry and under
a series of shaped wheels or runners carried in an adjustable frame, so that the
strip coming in contact with the wheels or runners is folded and bent to the shape
of the moveable jaw. The jaws are then traversed back on the table or gantry and
the strip removed.
The strip when removed is bent so as to be ready to be fixed to the edges of the
fillet and two of such strips (one for each edge of the fillet) are taken and placed
in blocks in which are holes for the reception of the pins or prongs. Above each
of these blocks is a pair of nipping jaws and the distance apart of each block and
each pair of jaws can be regulated according to the width of the fillet.
When the pins or prongs are in the holes in the blocks the C portion of the
strips rest between the jaws.
When the strips are in position a fillet is placed between the bent or portion
and the top and moveable jaw of both jaws is moved slightly forwards by means of
eccentric shafts and handles so as to be over the bent portion of the strip. The
top jaws are next moved towards the bottom fixed jaws by means of eccentric
shafts, or shafts and cams, and the Cor bent portion of the clip is tightly nipped
so that such clip is securely fixed to the edges of the fillet.
The blocks are adjustable end wise so that the holes in one may be brought in
correct relative position with the holes of the other.
Dated this 80th day of January 1898.

page_text: Continuing its forward motion the strip passes under the wheel or runner 13, the
bevelled face of which still further bends the edge, as shewn by Fig. 8 when the
shaping operation is completed after the table or gantry 1 has been traversed
back, the strip 9 is removed from the jaws 2. 3.
The spiral springs 19 causes the loose jaw 3 to move away from the fixed jaw 2
when the concentric side of the cams are moved opposite or against the jaw 2.
The strip 9 when removed is bent so as to be ready to be fixed to the edgos of
the foundation of the card fillet 14), and two of such strips 9 (one for each edge
of the fillet 14, are taken and placed in blocks 16. 16 in which are holes 17 (see
Figs. 9. 10. 11) for the reception of the pins or prongs 8 of the strip 9. Above
each of these blocks 16 is a nipping jaw 20, and the distance apart of each block 16.
and each jaw 20 can be regulated according to the width of the fillet 14 by means
of ordinary screw adjustment, such as at 21. 22.
When the pins or prongs 8 are in the holes 17 in the blocks 16, the C or bent
and shaped portions 23 of the atrips 9 are in the position shewn by Fig. 9.
When the strips are in position, a fillet 14 is placed between the bent or
portion 23, and the moveable jaws 20. 20. are moved slightly forward by means
of eccentric shafts 24 and handles 25, so that the edges 26 of the jawe 20 are
directly over the bent portion 23 of the strips 9. The moveable jaws 20 are next
moved towards the bottom fixed jaws or blocks 16, by means of eccentric shafts, or
shafts 27 and cams 28, operated by hand lovers 29, and the C or bent portion 23
of the clip 9 is tightly nipped betweon the jaws 20. 16, so that such clip 9 is
securely fixed to the edges of the fillet 14.
The blocks 16 are adjustable endwise by screw adjustment 21, so that the
holes 17 in one may be brought in correct relative position with the holes 17 of
the other block 16. Spiral springs 29ª serve to open or lift tho moveable jaws 20
when the concentric side of the cams 28 is against uuderside of the block or bed
piece 30.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, wo declare that what we
olaim is :-
(1.) The construction, arrangement, and combination of the parts constituting
the improved appliances for bending and shaping clips or clamps for securing card
clothing to the flats of carding engines, as herein described, and as illustrated by
Figs. 1 and 2 of the accompanying drawings.
(2.) The jawa 2, 3 for holding the strip and the shapeil wheels or runnors 11.
12. 13, all in combination as and for the purpose herein described, and as illustrated
by Fig. 1 of the accompanying drawings.
(8.) The construction, arrangement, and combination of parts constituting the
improved appliances for securing metal clips or clamps to the fillets of card clothing,
as and for the purpose herein dosoribed, and as illustrated by Figs. 9 and 10 of the
accompanying drawings.
(4.) The fixed and moveable jaws or blocks 16. 20, eccentric shaft 24, roda 27,
cams 28, all in combination, as and for the purpose herein described, and as
illustrated by Figs. 8. 10 and 11 of the accompanying drawings.
