NEEDLE SPRINGS FOR SEWING MACHINES
Year: 1885

page_text: DAVID YOUNG Bootmaker 33 Hanover St Edinburgh residing at 37 Thistle St
Edinburgh I do hereby declare the nature of my invention for NEEDLE SPRINGS
FOR SEWING MACHINES to be as follows:-
A spring is made of a length to suit the needle; without coming over the
point; and of a width which will leave just room for the thread to work without
getting chafed.
The spring is then passed over the needle of the sewing machine; enclosing both
the needle and the thread which passes through the eye of the needle, When the
needle comes down and passes through the material which is being sewn; the
spring comes down with the needle but; is arrested on coming into contact with
the material; and is pressed upwards; and at the same time presses the material
solidly together; and prevents the material from rising with the needle; when the
needle makes the first upward movement for the purpose of throwing out the loop
which the shuttle passes through.
-
It has the effect of making more solid work and of preventing miss-stitches.
The spring may be fastened at the top of the needle; or bottom of the needle
bar;
and be removed at pleasure; or it may be permanently placed inside the
needle bar and connected with the needle by a sliding rod.

page_text: DAVID YOUNG 33 Hanover Street Edinburgh Bootmaker I do hereby declare
the nature of my invention for NEEDLE SPRINGS FOR SEWING MACHINES and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
.
A spring a; spiral; or of any other shape; device; or pattern which may be
desired; and made of metal; or any other flexible material; is fitted on the needle
of the sewing machine; being fastened at the top of the needle B, or of any other
convenient part of the machine; and enclosing both the needle and the thread
which passes through the eye of the needle. The width of the spring; or the
aperture c in the spring being sufficient to allow the needle to work freely up and
down without chafing; or breaking the thread.
Or the spring may be placed inside the needle bar d of the machine; or may be
fixed on said needle bar; or on any other part of the machine; and be connected
with the needle by a sliding rod e; the eye for eyes F at the end of said sliding
rod being wide enough to allow the needle to pass through and work freely; the
rod or spring being fastened so that the end will not come down over the point
of the needle; when the needle is up and clear of the throat plate of the machine.
When the needle comes down and passes through the material g which is being
sewn; the spring or sliding rod comes down with it; but; the spring; or rod;
instead of passing through; is arrested on coming into contact with the material
which is being sewn; and is pressed upwards; and at the same time presses the
material solidly together; and prevents the material from rising with the needle
in the slightest degree; when the needle makes the first upward movement for
the purpose of throwing out the loop which the shuttle passes through; thereby
having the effect of making more solid work; with greater regularity of stitch;
and of preventing miss stitches; more especially on soft and elastic materials; or
irregular surfaces.
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:
1st The use of springs of whatever pattern; to fit and work on the needles; and
needle bars of sewing machines; for the purposes as herein set forth.
2nd The use of any flexible material which shall act as a spring; working on
the needles; or needle bars; of sewing machines; for the purposes as herein set
forth.
3rd The use of sliding rods working on the needles; or needle bars of sewing
machines said rods being connected with springs of any flexible material, for the
purposes as herein set forth.
