Improved Machine for Cutting and Perforating Textile Fabrics and
Leather.
I JOHN JAMES STORY, 367 Saint Ann's Well Road, Nottingham, Artist,
do hereby declare the nature of this invention to be as follows:-
Each machine consists of a bed plate supported by standards provided with bearings
for a shaft carrying a driving wheel, which may be caused to revolve by hand, tho.
shaft may be cranked and driven by a link and foot treadle, or the shaft may be pro-
vided with driving pulleys operated by a 'belt from a main shaft. Beneath the bed is
a framing having, vertical grooves in which a bracket slides, the lower end of the
bracket is connected by a link to a crank pin projecting from a grooved disk revolving
an axle secured to the framing the disk is driven by a belt passed round it and the
driving wheel. Above the vertical grooves the framing is provided with bearings in
which the ends of a tube revolve, the tube carries a hand wheel by which the attendant
may turn the tube to the right or left. Within the tube a rod is caused to rise and
fall, its lower end being connected to the top of the sliding bracket before named, in
which it is free to be turned either way by the attendant, the rod being provided
with a stud projecting from one side which engages with a slot in one side of the tube
above the hand wheel.
The upper end of the rod is split vertically to receive the lower end
of a pointed cutting blade which is firmly clamped by a set screw in a collar on the
end of the rod, which lies within the arms of a U shaped bracket screwed on the
upper end of the tube.
.
The arms of the U shaped bracket are secured to the underside of a
circular plate provided on the top with an exteriorly screw threaded ring, upon which
is screwed a disk free to turn in and rest upon the circular flange of a perforated
plate, the top of which lies flush with the top of the bed plate. The circular plate and
the disk before named are each slotted to admit of the free passage of the pointed
cutting blade, which may be changed for a thinner or a thicker blade, the slotted disk
being also changed to suit the blade employed. Above the disk is an adjustable presser
foot slotted vertically to allow of the free passage of the blade in use, the presser foot
terminates in a flange at the top which is free to turn in a bearing capable of adjust-
ment vertically on one end of a bracket arm secured to the bed of the machine. The
presser foot is held down by a spring onto the materials to be cut or perforated to
prevent them rising from the bed plate at each upward movement of the blade.
By means of a machine constructed as above described several superimposed, thick-
nesses of fabrics or leather may be cut through or perforated to any required
pattern, when cutting a pattern the cutting edge of the cutting blade is turned.
to face the line of the pattern by means of the hand wheel on the tube before.

Figure 2 shows a right end view of the same, with bed plate and a platform above
it in section..
Figure 3 is an enlarged view of an adjustable presser foot with its bearing shown
partly in section.
Figures 4, 5 and 6 show portions of the machine each severally referred to here-
after, and
Figures 7 show side views of various perforating cutters I employ.
Each machine consists of a bed plate A see Figures 1 and 2 supported by standards
(not shown in the drawings) provided with bearings for a shaft carrying a driving
wheel, the shaft may be caused to revolve by hand or it may be cranked and driven
by a link and foot treadle, or the shaft may be provided with driving pulleys operated
by a belt from a main shaft as most convenient.
Bolted to the bed plate is a framing B beneath which arms B1, B2, B3 project, and
form bearings for a shaft B provided with a grooved pulley at its right end revolved
by a belt passed round it and a pulley B' secured on a shaft B carried by the framing B
above the bed plate, the shaft 13 is provided with a driving pulley B operated by a
belt from a main driving wheel before described.
The arms B', B have vertical grooves in which a bracket C slides connected at its
lower end by a link C¹ to an eccentric C2 carried by the shaft B* provided with a disk
and counter weight C. Above the vertical grooves the framing is provided with
bearings B³, B³ in which the ends of a tube D revolve, the tube carries a hand
wheel D by which the attendant may turn the tube wholly or partly round either
way. Within the tube a rod D2 is caused to rise and fall, its lower end being
swivelled to the top of the bracket C, in which it is free to be turned either way by
the attendant, the rod is provided with a stud D³ projecting from one side which
engages with a slot in the tube above the hand wheel. The upper end of the rod is
split vertically to receive the lower end of either of a series of pointed cutting
blades D' four of which are shown in side view at Figures 7, which is firmly clamped
by a set screw in a collar D³ on the end of the rod, an enlarged view of the split rod,
collar, and set screw, is shown in plan at Figure 6.
The upper end of the rod lies within the arms of a U shaped bracket screwed or
otherwise.secured on the upper.end of the tube D, the arms of the bracket are secured
to the underside of the ends of a plate forming a circular stud D at the centre of.
its length, the top of the stud is free to turn in, and lies flush with the top of a work
plate 17 carried by the top of the framing B. The circular stud is slotted vertically
to admit of the free passage of one of the pointed cutting blades, which may be
changed for a thinner or a thicker blade, the circular stud being also changed to suit
the blade employed. An enlarged view of one of the vertically slotted studs is shown
in plan at Figure 5. Above the bed plate a platform A' is provided the top of which
surrounds and lies flush with the top of the work plate, to form an extended surface
for the work to lie upon, portion of the platform in front of the work plate forms a
leaf A hinged to the platform at its left end and held flush with the top by a
button A³ at its right end, upon the leaf being lowered the platform may be readily
removed when required. Above the slotted circular stud is a presser foot E see

page_text: Figure 3, slotted through vertically to allow of the free passage of the pointed cutting
blade in use, above the slot the foot is provided with a flange which rests upon a
split collar El secured by screws to the lower end of a bearing rod Ẹ the upper
end of which is screw threaded and provided with a nut E³ and set screw E by which
the rod may be adjusted vertically the requisite height above the top of the work
plate D7, according to the thickness or thicknesses of the fabric or leather to be
perforated and cut.
The bearing rod E³ is free to slide vertically and turn either way in a bracket E³
carried by an arm E secured to the bed plate of the machine, the arm has a bent
wiro E' hinged to it which clips the presser foot E when raised clear of the cutter to
adjust or remove the material to be cut.
An underside view of the collar E and screws is shown separately at Figure 4.
The weight of the bearing rod holds the lower end of the presser foot close to the
material and keeps it steady while it is being cut, and allows varying thicknesses of
the material to readily pass under it, the foot turning freely either way with the
cutting blade at the will of the attendant. The cutters shown at Figures 7 are pointed
at the top and formed with a cutting edge on the left side to cut downwards at any
angle varying from 40 to 80 degrees, between the two dotted horizontal lines at D*
either straight or slightly curved, terminating at the lower end in a guard or
stem made wider at the bottom to allow it to he firmly clamped in the upper split end
of the rod D'.
By means of a machine constructed as above described several superimposed thick-
nesses of fabric or leather may be cut through or perforated to any required pattern,
when cutting a pattern the cutting edge of the cutting blade is turned to face the
line of the pattern by means of the hand wheel D¹ while the attendant guides the
fabric or leather to the cutter.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
'
1. The cutters D carried by the rod D2 and sliding vertically in a revolving stud D*
substantially as described.
2. The revolving and slotted presser foot E for receiving guarding and revolving
with the vertically moving cutters D4 substantially as described for the purposes
specified.
3. The construction and employment of machines for cutting and perforating
textile fabrics and leather substantially as described and illustrated in the drawings
annexed.
