"
We, CHARLES WHITE, Gentleman, and MICHAEL HOLZMAN, Merchant, both of
Baltimore, Maryland, United States, do hereby declare the nature of our invention
for "IMPROVEMENTS IN A MACHINE FOR CUTTING EMBROIDERED FABRICS and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:—
The object of the invention is to provide a movable knife, which is adapted to
separate the goods on a line with the outer edge of the embroider.
We attain this object by mechanism illustrated in the accompanying drawings, in
which;
Fig. 1, is a top view, with parts removed; Fig. 2, a longitudinal section; Fig. 3,
front end view; Fig. 4, an end view, showing position of belt pulleys; Fig. 5,
detail view of knife, showing goods partly cut; Fig. 6, same as Fig. 5, with goods
removed; Figs 7 & 8, section views of Figs 5 & 6; Fig. 9, a detail view showing
method of cutting.
Similar letters refer to similar parts throughout the several views.
The bed plate A is supported by projecting legs a, which are secured to a frame
or table of any suitable kind. From the under surface of the plate A, project
hangers b&b, which forms bearings through which the shafts C and C¹, pass. On
the ends of said shafts are rubber sleeves c, c, which engage with each other, and
forms the feeding device. To the opposite end of the shaft C, is attached tho
driving pulley D, which contains two grooves, one being occupied by the driving
belt, the other by the belt d, which passes over the pulley e, to the idle pulley e¹,
thence to the pulley e³, on the spindle f, from which it returns to the driving
pulley D, by passing over a second idle pulley e, the belt being crossed between
the pulleys e, on the spindle f, and the idlers e¹, and e³, to move or rotate the
knife F, in the proper direction, in relation to the movement of the goods, while
being cut. The spindle f runs in the bearings g, g, between which is placed the
pulley e³, the lower end of the spindle, carrying the cutting knife F, which moves
on a plane parallel to that traversed by the goods, part of which (as it is cut)
passing over the knife F, and the other part passing under, to the feed rollers c, c,
which draws the material forward.
The knife F rotates in a circular opening in the bed plate A, provided with a
slot g', at ono side to allow the goods to pass downward, to the feed rollers c, c
On the side opposite to the slot g', of the circular opening, is a semi-annular
elevation g³, (see detail Fig. 6,) the height of which regulates the distance from the

page_text: outer embroidered edge, to where the goods are separated; the nearer the upper
surface of the projection g³, is to the surface of the knife plane, the closer the
material will be cut to the embroider, or vice-versa.
The semicircular plate h is pivoted at one end to the bed plate A, which permits
it to be moved to and from the knife F, whose function is, to prevent the goods
from puckering as they are cut, and its position is, when operating close to the
edge of the knife, as seen in Fig. 5.
The material is held in its place by the guide i, supported on the rod ", which
passes through the support n, and has an inward and outward movement, to
accommodate the different size embroider, and when set in the proper position, is
there held by means of the thumb-screw i².
The shaft I runs in bearings 1, 2, suspended from the bed plate A, and is provided
at one end, with the pulley e, by which it is driven by the belt d, the other end
having a slot m, in which the cut goods are inserted, to be wound into a roll, as it
passes from the feed-rollers c, c. The shaft I and its attachments are not essential
to the cutting device, and may be dispensed with, as its functions are, only to
facilitate the handling of the goods after they are cut.
In operating the machine, the guide i, is raised and the plate h, thrown back,
permitting the goods to be placed in position, (a few inches of which are previously
cut by hand) the end containing the embroider being passed over the knife F, and
the other part being passed through the slot g', to the feed rollers c, c, thence to the
winding roller or shaft I, and placed in the slot m¹. The guide, is then placed
on the goods, with its guiding surface i³, bearing against the outer embroidered
edge p, and the plate h, moved in or placed around the knife F. The embroider
being placed in relation to the knife, so that the inner angles p', of the scollops,
will just pass within the periphery of the knife F.
As the goods are moved forward the section containing the embroider, is held up
while the other section is drawn down, thus exposing only that portion of the
fabric, which is in close proximity with the embroider to the knife's cutting edge.
The knife moving in a plane parallel with the fabric, any regular or irregular line
of embroider may be cut, by this method.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. The method herein described of cutting the fabric at the edge of the
embroider, by passing the section containing the embroider on one side of a
movable knife and drawing the other section out therefrom, at an angle to the
plane of the embroidered section, for the purpose herein specified.
2. In a machine for cutting embroidery, a knife moving in a plane parallel with
the embroidered goods, whereby the line of the embroidered edge may be followed
by the edge of the knife, as shown and described.
3. The combination with a knife moving in a plane parallel with the embroidered
goods, mechanism whereby said knife is driven.
4. A movable knife adapted to separate the fabric at the edge of the embroider,
as the embroidered goods are passed in a straight line towards said knife.
