purposes.
MARTIN CARMODY Tailors' Cutter 49 St. George's Terrace Harrington Road
Workington Cumberland do hereby declare the nature of this invention to be as
follows:-
--
I provide the apparatus in the form of a scissors provided with loose cutting
blades. I provide the ends of the blades which are nearest to the handles with a
hollow cutter and punch which is used in cutting the eye out at the end of button
holes. The eye may be cut without the punch by having a hollow cutter top and
bottom the blades cutting the other part of the hole to the required length.
The scissors are joined together by a pin or screw through the handles. The
scissors been joined in the handles leaves both ends of the blades free-a
suitable distance been allowed from the joining of the handles to allow the hole
to be cut any required distance from the edge of the material. The length of the
hole may be regulated by a movable screw between the handles.

Improvement in Scissors for Cutting Button-holes and for other
purposes.
I, MARTIN CARMODY, of 49 St. George's Terrace, Harrington Road,
Workington, in the County of Cumberland, Tailors' Cutter, 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 :-
In cutting button-holes it has hitherto been necessary either to punch the
complete hole out by means of a suitable die or cutter, or the eye part of the hole
has been punched out and the slit or long part of the button-hole cut by means of
so-called button-hole scissors, that is to say, by scissors constructed in such a
manner as to cut a slit at a given distance from the edge of the cloth or other
material, the length of the said slit being regulated by means of an adjusting
screw. The use of a punch however involves a considerable expenditure of force
as compared with that required by the shearing action of a pair of scissors. By
this invention I produce scissors by means of which a complete button-hole can
be cut by the shearing action of ordinary scissors; the length of the slit or long
part of the button-hole being adjustable, the scissors being also adaptable for use
as ordinary cutting scissors when so required.
A further object of this invention is to produce a pair of scissors for cutting a
slit at an adjustable distance from the edge of the material, as for example, the slit
or long part of a button-hole, wherein the whole length of the blades is effective
for cutting purposes, the scissors being also adaptable as ordinary cutting scissors
when so required.
In the accompanying drawings
Figures 1 and 2 shew front and side elevations of a pair of scissors constructed
in accordance with my invention and designed for cutting a complete button-hole
at one operation and by the ordinary shearing action;
Figure 3 shews in part elevation another position of the same scissors.
Figures 4, 5, and 6 are similar views of a modification of the scissors shewn in
Figures 1 to 3.

page_text: Figures 7 and 8 are front elevations shewing two different positions of a pair of
scissors for cutting a slit at an adjustable distance from the edge of the material.
Figure 9 shews an enlarged perspective view of the cutters and part of the
blades and
Figure 10 shews the same in elevation looking in the direction of the arrow X
Figure 9.
Referring to Figures 1 to 6, 1 pivot the handles A together at C and provide
each of them with an extension arm B above the pivot and parallel to the direction
of the handles. To these extension arms B the blades D D' are secured in any
suitable manner. On the bottom of each blade and at right angles to the cutting
edge E thereof (see Figures 9 and 10) I form or attach a hollow cutter, or a
hollow cutter F on one blade, and a solid cutter G on the other, the cutter F
being large enough to allow the other cutter G to enter thercinto as and when the
scissors are closed up. The upper edges of the cutters F and G are convexed or
otherwise curved upwards on one or on both sides as shewn at f, f', and g, g', in
Figures 9 and 10, and these edges f, f, and g, y, are sharpened so as to form the
cutting edges for the eye of the button-hole. The front of the large cutter F is
furnished with a longitudinal slit H alongside or contiguous to the blade D so as
to allow the opposite blade D' to enter therein as the scissors are closed up.
In the form of my invention shewn in Figures 1, 2, and 3 the length of the slit
or long part of the button-hole is regulated by the position of the nut J on the
bolt or threaded rod K forming part of, or attached to, the extension arm B. The
two extension arms, the cutters and G, and the shoulder L form an open frame
or throat to the scissors; the length measured from the cutters and G being the
distance which the scissors can be passed from the edge of the cloth or other
material before the eye of the button-hole is cut. The position of the nut K on
the bolt will determine the amount of closing up of the scissors and thus will
regulate the length of the slit or long part of the button-hole. In the position
shewn in Figure 1 the scissors can be closed up so that the cutting blades will
meet as far as the points marked M: to make a longer slit to the button-hole, the
nut Jis screwed further on to the bolt K and to make a shorter slit the nut is
turned in the opposite direction.
'
The manner in which the scissors may be adapted as ordinary cutting scissors is
shewn in Figure 3. In this case the nut J is screwed down home on to the bolt. K
and the nut being somewhat larger in cross section than the extension arm B will
partly overlap the same and will thus form a stop against which the projection N
on the shoulder L will abut, as shewn in Figure 3, and thus prevent the scissors
being further opened. In this position the scissors cannot be opened sufficiently to
open the cutters F and G and the scissors may be completely closed up, thus the
cutting blades D and D' only are in operation and the scissors can thus be used as
ordinary cutting scissors.
In the modified form shewn in Figures 4, 5, and 6 the stop piece O with the
set screw P take the place of the nut and bolt K. The stop is attached to
the handle L below the pivot C and is capable of being rotated so as to abut
against the opposite handle and fit into any of the notches N³ shewn and thus
prevent the scissors from closing up more than the required distance. A notch N
is formed on the underside of the shoulder L of the handle, and when the stop
piece is placed in this notch N2, as shewn in Figure 6, the scissors cannot be
opened beyond the position shewn, but may be completely closed up. The scissors
are thus adapted for use as ordinary cutting scissors.
The scissors shewn in Figures 7 and 8 are constructed and operate in substantially
the same manner as the scissors shewn in Figures 1 to 3, except that there are no
cutters and G so that no eye is produced in the cutting of a button-hole, and
the bolt K is attached to a block Q'sliding in the slot R and secured in any position
therein by means of a set screw. By this means the distance of the commencement
of the hole cut from the edge of the material, can be regulated when so required.
If desired the bolt K in the form of scissors shewn in Figures 1 to 3
may
also

page_text: be made to slide longitudinally in the extension arm and for the same purpose as in
the modification shewn in Figures 7 and 8.
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 construction and use of scissors for cutting a complete button-hole at
one operation by a shearing action, substantially as described and shewn.
(2) The construction and use of scissors for cutting a complete button-hole at
one operation by a shearing action, with means for regulating the opening and
closing of the scissors, substantially as and for the purposes hereinbefore described
and illustrated in Figures 1 to 6, and 9 and 10.
(3) The button-hole scissors described with reference to Figures 1 to 3 and
9 and 10 of the accompanying drawings, whereby a complete button-hole is cut at
one operation by a shearing action, the handles of the scissors being pivotted
together at C, and furnished with extension arms B to which the blades D and D'
are secured, the said blades having cutters F and G secured to or formed on their
lower ends at right angles to the cutting edges E of the blades, the cutters F and G
being convexed or otherwise curved upwards on one or both sides as at f, f', and g, g',
and sharpened so as to form the cutting edges for the button-hole eye with means
for regulating the distance to which the blades may be opened or closed, and for
regulating the distance in from the edge of the material where the cut may
coinmence consisting of a bolt K fixed to, or adjusted on, the extension arms B,
the nut J rotatable on the said bolt, and the projection N on the shoulder of the
other handle, arranged and operating substantially as and for the purposes herein-
before set forth and illustrated.
(4) The modified form of my invention shewn in Figures 4, 5, and 6 of the
accompanying drawings wherein the regulation of the opening and closing of the
blades is effected by the use of the rotatable stop O, adjustable by means of
the set screw P, engaging with the notches N' and N³, substantially as and for the
purposes described.
(5) The modification shewn in Figures 7 and of the accompanying drawings
for producing a straight button-hole cut or slit only, with means for regulating the
opening and closing of the blades, and for regulating the distance in from the edge
of the material where the cut may commence, substantially as and for the purposes
herein described.
(6) The use in combination with scissors designed for cutting the long part or
slit of a button-hole, of the cutters F and G, attached to, or formed on, the
blades D and D' designed to enter one within the other and having cutting edges
so formed as to shear a circular hole or eye from the material at the commencement
of the long cut or slit, the cutter F being slit at its junction H with the blade D so
as to allow the opposite blade D' to enter thereinto and allow the two blades to
close up together one beside the other, substantially as herein described and shewn
in Figures 9 and 10 of the accompanying drawings.
(7) My improvements in scissors for cutting button-holes and for other purposes
substantially as described.
