I, ERNEST NOWILL "Rosendale" Carson Road West Dulwich, S.E. Manufacturer's
Clork do hereby declare the nature of this invention to be as follows:-
The Button Hole Scissors shown in the drawings annexed may be regulated, so as
to make different sized Button Holes, by means of the adjusting nut "A" working
upon the fixed screw "B"
(represented in the drawings hereunto annexed)
and thereby preventing the blades closing at, or towards, the points, (according
to the distance the nut "A" is unscrewed from the shank "C" & towards the
shank "D").
What I claim is
$6
The arrangement of the screw "B" & the nut "A," & the hole in the shank "D,"
which allows the head of the screw "B" to pass through the shank "D" and so
make a button hole the full length of the blade when closed (as Fig. 2) in drawings
annexed.

page_text: Figure 1 is a plan of a pair of button hole scissors constructed according to my
invention representing the blades parted beyond their cutting position in order clearly
to show the construction thereof.
Figure 2 is a similar view but showing the blades in the position they would
assume at the commencement of a cut.
Figure 3 is a similar view but showing the blades in the position they would
assume at the termination of a cut, the regulating device being adjusted for the
smallest button hole.
Figure 4 is a similar view but showing the blades completely closed or in the
position they would assume at the termination of a cut the regulating device being
adjusted for the largest button hole and
Figure 5 is a detail view of the regulating device drawn to an enlarged scale.
In the several figures of the drawing like parts are indicated by similar letters of
reference.
a represents the blades of the scissors which are notched or cut away at the point a¹
as is usual in scissors of this class in order that the cut may commence at a given
distance from or within the edge or selvedge of the fabric.
b, b¹ represent the "shanks" of the scissors which are approximately of the ordinary
shape and dimensions.
According to my invention however I rivet or otherwise fix to the shank ba stud
or spindle formed with a screw thread thereon, and upon this threaded stud or
spindle I place a nut e¹ formed with a corresponding screw thread therein and I burr
over or rivet the end of the stud or spindle c in order to prevent the nut c¹ becoming
accidentally detached therefrom.
The shank b' has a hole or recess 6 formed therein or therethrough in order to
receive the end of the spindle c at such times as it projects beyond the nut and
thus allow of the scissors being partially closed in the formation of a button hole of
medium size as shown at Figure 3 or completely closed in the formation of a button
hole of the largest size, or for transport, as represented at Figure 4.

page_text: The bore of the nut c' as will be seen more clearly on reference to Figure 5 is formed
of two different diameters, the smaller part c² of the bore which extends about half
way through the nut c¹ having a screw thread formed therein to engage with the
screw thread of the spindle or stud c and the larger part of the bore being formed
with a plain surface thereto, the enlarged or rivetted end of the spindle c being unable
to pass through the smaller part 2 of the nut c¹ effectually prevents the latter
becoming detached therefrom.
The object of this peculiar formation is to give the nut c¹ a sufficient extent of
traverse along the screw threaded stud or spindle c and to enable it to project beyond
or overhang the same so as to admit of the necessary regulation of the degree of cut-
of the scissors and yet enable me to employ a stud or spindle c of such length that
when the scissors are in their closed position as represented at Figure 4 the end
of the spindle c will lie snugly within and will not project beyond the shank b¹
thereof.
If for example I employed a nut c¹ having a screw thread formed throughout the
entire length of its bore, the enlarged head of the spindle c, which is necessary in
order to prevent the parts becoming detached, would not allow the nut c¹ to project
beyond or overhang the end of such spindle c and consequently 1 should be unable
to obtain the degree of adjustment necessary for small button holes unless I were to
employ a stud or spindle of such length that it would project beyond the shank ¹
when the scissors were closed.
The action of the device is as follows. When the scissors are in use the nut c¹ is
screwed along the spindle c until it is in such a position that by acting as a stop to
the shank b¹ it limits the closing motion of the blades a to the extent necessary to
produce a button hole of the required size and after having obtained this adjustment
any number of button holes may be cut all of equal length.
When the scissors are out of use the nut c¹ is screwed along the spindle c until it
abuts against the shank b and the scissors are then closed the projecting end of the
spindle c lying snugly within the hole or recess 6' in the shank 6.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that
what claim is
1. In button hole scissors the employment of a nut c¹ working upon a screwed
spindle c projecting from the inner side of one of the shanks thereof in manner sub-
stantially as herein shown and described and for the purpose stated.
2. In button hole scissors the employment of a nut working upon a screwed
spindle c projecting from the inner side of one of the shanks 6 and passing into a hole
or recess 6 in the shank b¹ all constructed and arranged in manner substantially as
herein shown and described and for the purpose stated.
