Each machine consists of a metal bed plate and two end standards, each standard
has a vertical slot and a curved slot, in the curved slots bearings slide in which the
axles of two fabric carrying rollers revolve, the upper roller is held down onto the
lower roller by a coiled spring at each end, the upper roller may be changed for one
of a smaller or larger diameter, the circumference of such roller being equal to the
length of pattern to be cut the vertical slots have studs sliding in them which project
from the ends of a presser plate which is pulled down by a spring at each end onto
a bed plate having a cutting edge at the back, the front edge nearly touches the
lower roller which is covered with india rubber, in front of the lower roller is a
plate over which the fabric to be cut is drawn at the back of the cutting edged plate ;
close to it is a vertical cutting blade which rocks on an axle carried by a bracket
projecting from the left end standard, the rocking being effected by a truck which
revolves on a stud projecting from the outer end of the blade engaging with a
grooved cam the front of the cam is provided with a toothed bevel wheel driven
by a similar wheel on the left end of a shaft revolving in bearings in the standards,
this shaft at each end carries a cam which at each revolution of the shaft raises
the presser plate clear of the cutting edged plate to allow the length of a pattern
to pass between them. The right end of the shaft next the cam is provided with
two toothed wheels the outer one gearing into a similar wheel on the side of a
fly wheel which revolves on an axle projecting from the right standard, the inner
toothed wheel gears into the outer one a pair of wheels secured together and
revolving on the same axle as the fly wheel, the inner wheel of the pair gears
with a toothed wheel on the right end of the upper roller axle. Each revolution
of the fly wheel causes one length of pattern to be passed between the rollers to
the cutting edge of the bed plate the rollers then stop revolving while the vertical
cutting blade severs the fabric and after the cutting edge of the blade has risen
somewhat above the cutting edge of the bed plate, it remains stationary until the
rollers have again revolved and passed another length of pattern to the cutting
edge the movement being then repeated.

Improved Machine for Cutting Patterns of Lace and other Fabrics.
I HERBERT HENSON, Cottage Grove New Chilwell Nottinghamshire Lace Manu-
facturer 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 :-

page_text: wheel broken away, and three pair of toothed wheels removed to show other parts of
the machine.
Figures 3. 4. and 5 are right side view of three pair of toothed wheels, and
Figures 6 to 12 show seperate portions of the machine each severally referred to
hereafter.
Each machine consists of a metal bed plate A and two end standards B, B, see
Figures 1, and 2, each standard has a vertical slot B¹ and a curved slot B' in the
curved slots bearings slide in which the axles of two fabric carrying rollers revolve,
the upper roller C has three or more grooves cut in its circumference, the number of
grooves varying with the width of the rollers. In each groove a narrow plate
spring C, lies and projects towards the back of the machine where they are attached
to the under side of the front edge of a presser plate, these springs prevent the fabric
passed between the rollers from lapping round the upper one, which is held down on
to the lower rubber covered roller by a coiled spring C³, at each end. Each spring
is kept in position by its lower end engaging with a stud which projects from the top
of the bearing, the upper end of the spring engaging with a pin projecting from the
underside of a plate shown in plan at Figure 6 which slides in grooves cut in the
sides of the slot B³, of the standards, the position of the plates in the slots depending
upon the diameter of the upper roller employed and the pressure required.
The roller C may be changed for one of a smaller or larger diameter, the circum-
ference of the roller being equal to the length of pattern to be cut.
The vertical slots B¹ have studs sliding in them which project from the ends of a
presser plate B³, shown only at Figure 2 each stud being secured to a vertical
rod B*, which slides in bearings projecting from the outside of the standard, the
lower end of each rod carries an open helically coiled spring B, which pull the
presser plate down onto a bed plate B, "shown by dotted lines at Figure 1, and
endways at Figure 2," and firmly holds the lace or other fabric down on to the
bed plate while the cutting blade Ĕ descends.
The bed plate is supported at each end by bearing arms B7 projecting from the
standards, and is adjusted by two screws passing through studs B8 projecting from
the bottom of the bed plate bearing upon the arms B', the back of the plate forms
a cutting edge, and the front is bevelled so that its top edge will nearly touch
the rubber covered roller C² in front of which is a plate D supported by brackets D³
secured to the standards.
One end of the fabric to be cut is placed upon the plate by the attendant and
fed to the rollers which carry it through to the cutting edge of the bed plate,
close to which is a vertical cutting blade E, which moves in a slot E¹, in the left
end standard.
The outer end of the blade is secured to a plate E³, which rocks on an axle E³, a
front view of which is shown at Figure 7, and a right edge view at Figure 8, the
axle is supported by a bracket E projecting from, and capable of adjustment upon
the left end standard, a front view of the bracket is shown at Figure 9 and a left
edge view at Figure 10.
The vertical movements of the cutting blade are effected by a truck E³, carried by
a stud secured in the lower end of the plate E2 engaging in the groove of a cam E³,
a back view of the cam is shown at Figure 11, and a right edge view at Figure 12.
The front of the cam is provided with a toothed bevel wheel F, gearing into and
driven by a similar wheel F', secured on the left end of a shaft F' revolving in
bearings formed in the standards, this shaft near each end carries a cam F³, which at
each revolution of the shaft raises the presser plate B³, clear of the cutting edged
bed plate B6, to allow the length of a pattern to pass between them.
The right end of the shaft is provided with two toothed wheels, the outer one G, is
oval and gears into a similar oval wheel G¹, on the left side of a fly wheel H, which
revolves on an axle projecting from the right standard, the inner toothed wheel G²,
gears into the outer one G³, of a pair of wheels secured together and revolving on the
same axle as the fly wheel, the inner wheel G4, of the pair gears with a toothed
wheel G³, secured on the right.end of the axle of the upper roller C..

page_text: The wheels G' and Gº, are shown seperately in their relative positions in side view
at Figure 3, the wheels G³, and G³, in side view at Figure 4 and the wheels G and G¹
at Figure 5.
The fly wheel H is provided with a handle H¹ shown only at Figure 2 by which
the machine may be driven.
Each revolution of the oval wheel G₁ gearing into the wheel G will cause the
roller C to slowly commence its revolution increasing its speed, and then gradually
stopping and remaining at rest while the cutting blade E cuts off one length of
fabric.
The wheel G2 is secured to and revolves with the lower oval wheel G, the wheel G²
at each revolution moving the upper wheel G³ only half round, and as the wheel G
is secured to and revolves with the wheel G³, the wheel G, and the roller C is only in
motion during one half of the revolution of the wheels G³ and G resting the other
half of the revolution while the blade E cuts off a length of fabric.
Each pattern as it is cut off falls onto and slides down a plate H2 supported at each
end by a rib H³ projecting from each standard.
Besides employing rollers C of different diameters for cutting various lengths of
patterns, I may vary the diameter of the wheels G, G³, for that purpose. If wheels
of the same diameter are employed the length of pattern cut will equal half the
circumference of the roller C, and by placing the wheel G₁, on the axle of the
roller C, and the wheel G5, on the axle of the fly wheel, lengths of pattern will be
cut equal to one quarter the length of the circumference of the roller C.
The combined movements of the machine are as follows, each revolution of the fly
wheel causes one length of pattern to be passed between the rollers to the cutting
edge of the bed plate, the rollers then stop revolving, the presser plate immediately
descends, holding the fabric firmly on the bed plate while the vertical cutting blade
severs the fabric, the presser plate then rises and after the cutting edge of the blade
has risen somewhat above the cutting edge of the bed plate they remain stationery
until the rollers have passed another length of pattern to the cutting edge of the bed
plate, the movements being repeated as required.
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 :-
:-
The construction and employment of an improved machine for cutting patterns of
lace and other fabrics substantially as described and illustrated in the drawings
annexed.
