Improvements in Sewing Machines.
I, DONALD NOBLE, of the Wheeler and Wilson Manufacturing Co., of 11 to 21,
Paul Street, Finsbury, Engineer, 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:-
My invention relates to sewing machines and has reference to a scissors attach-
ment therefor which is operated by the feed of the machine and whereby figuring
or lettering may be simultaneously cut out of one piece of fabric and attached
by sewing to the piece of fabric forming the garment or other article under
treatment, for the production of "applique or similar work.
"
According to my invention I attach to the presser foot of the sewing machine,
a knife which has a downwardly projecting cutting edge and forms the top jaw
of a scissors the bottom jaw of which is carried by a lever pivoted to a bracket
carried by the presser foot or its rod. The said lever is normally depressed by
means of a spring, and the upper jaw rises and falls with the presser foot as the
latter is actuated by the feed mechanism of the machine, the scissors being thus
actuated.
In order that my invention may be clearly understood and readily carried into
effect I will now proceed to fully describe the same in connection with the accom-
panying drawings, in which:
Figure 1 is an elevational view of part of a sewing machine having my inven-
tion attached thereto, and showing the scissors closed.
Figure 2 is a similar view to Figure 1 but shows the scissors open.
Figure 3 is a plan from below of the presser foot and attachment.
A is the feed rack of the sewing machine operated in the well known manner.
B is the presser foot of the machine which has the bracket 6 cast on or attached
thereto, and is removably attached to the presser foot bar by means of the screw b¹.
C is the knife which forms the top jaw of my scissors attachment and is attached
to the presser foot by means of the screws CC. c is a groove in the knife C
which enables the cutting edge of the latter to stand clear of the presser foot and
operate at a point just outside the line of stitching. is a hole which passes
through the knife C and in which the needle K works. D) is a lever which
forms the lower jaw of the scissors and is pivoted to the bracket bat d. This
lever D is provided with an upwardly projecting cutting edge d' which co-
operates with the knife C and has a sole da for a purpose hereinafter referred to.
E is a spring one end of which bears upon the lever D and serves to normally
depress it, while its other end is fixed to the bracket b. is a slot in the
lever into which a pin 62 fixed to the bracket b projects to limit the movement
of the lever. F is a spring catch attached to the bracket 6 and is for the pur-
pose of holding up the lever and lower cutting elge of the scissors out of action
if it is desired to use the sewing machine without the scissors. The operation
of the apparatus is as follows;-The presser foot is raised by the usual lever the
piece of fabric, leather, or other material M forming the article under treatment

page_text: is then placed over the feed rack and under the presser foot, the spring catch F
is then released and the lever D and knife depressed by the spring E to a
point below the sole of the presser foot, the piece of cloth leather or other fabric
or material m from which the figuring is to be cut is then placed between the
knife and the presser foot carrying the knife C; the presser foot is now lowered
onto the work. There are now two layers of fabric or other material between the
presser foot and the feed rack, the upper of which layers is situated between the
jaws of the scissors, the sole d² of the lower jaw of the scissors forming a flat
broad surface and bearing upon the top surface of the lower layer of fabric or
other material. When the sewing machine is now operated the two layers of
fabric or other material are united by stitching and as the feed rack rises and
falls the presser foot and knife C rise and fall also; the lever D. does not how-
ever rise and fall with the feed but the sole is kept depressed upon the upper
surface of the lower layer of material or fabric by means of the spring E, so that
as both layers of material are fed to the machine the top layer thereof will be
cut by the scissors along a line, just outside and parallel to the line
of stitching, and the top layer thus formed into a pattern and simultaneously
attached to the bottom layer; the outline of the said pattern being controlled
by means of guiding the layers of material in any desired direction.
If it is required to use the machine as an ordinary sewing machine, the
lever is raised out of operation and retained by the spring catch F or equiva-
lent means. I have described my invention in connection with a single needle
machine, but it is obvious that it may also be applied to a double needle
machine, in which case a scissors attachment is fitted to each side of the presser
foot so as to operate outside and parallel to the lines of stitching..
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
I claim is;-
-
1. In a sewing machine, means attached to the presser foot and actuated by
the feed mechanism thereof, whereby the top layer of two layers of fabric or
other material superposed one upon the other is simultaneously cut into any
desired form whilst the said form is being sewn to the bottom of the two layers,
substantially as described.
2. In a sewing mechine, a scissors attachment the top jaw of which is fixed
to the presser foot, and the lower jaw of which is carried by a lever actuated by
a spring and fulcrumed to a point which rises and falls with said presser foot,
substantially as described and for the purpose specified.
3. The combination with the scissors attachment referred to in the preceding
claim of means for rendering the said attachment inoperative when required, sub-
stantially as described.
4. A sewing machine fitted with a scissors attachment constructed and operat-
ing substantially as herein described and for the purpose specified.
