PROVISIONAL SPECIFICATION.
Improvements in or applicable to Sewing Machines.
I, CARL THEODOR NEUMANN, of Dresdenerstrasse, Grossenhain, in the-
Kingdom of Saxony, Shoemaker, do hereby declare the nature of this invention
to be as follows:-
This invention relates to Improvements in or applicable to Sewing Machines
and has for object to provide means to avoid the breaking of the needle by
preventing the shuttle coming into contact with the needle if the latter gets out of
its normal position; also to cause the loop to be moved somewhat on one side as
it leaves the needle whereby practically a perfect loop is formed.
For this purpose I provide a plate or casing placed under the work or sewing
plate, the part of the plate next the needle being so curved that the thread which
forms the loop is guided to the point of the shuttle, a slot in the upper part of the
plate serving to allow free passage to the locked thread. The needle groove
which has hitherto usually been made to coincide with the centre of the needle is.
now placed on one side of it, the surface towards the needle being rounded off.
Dated this 31st day of March 1894.

COMPLETE SPECIFICATION.
Improvements in or applicable to Sewing Machines.
I, CARL THEODOR NEUMANN, of Dresdenerstrasse, Grossenhain, in the-
Kingdom of Saxony, Shoemaker, 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:-
This invention relates to Improvements in or applicable to Sewing Machines
and has for object to provide means for preventing the shuttle coming into.
contact with the needle if the latter gets out of its normal position; also to cause
the loop to be moved somewhat on one side as it leaves the needle whereby
practically a perfect loop is formed.
For this purpose I provide a plate or casing placed under the work or sewing
plate and partially covering the needle-groove, the part of the plate next the
needle being so curved that the thread which forms the loop is guided to the point
of the shuttle, a slot or notch in the upper part of the plate serving to allow free
passage of the locked thread. The slot in the needle-groove which has hitherto
usually been made to coincide with the centre of the needle is now placed on one
side of it, the surface towards the needle being rounded off.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which:
-
Figures 1 and 2 are a sectional elevation and sectional plan respectively of part
of a sewing machine having my invention applied thereto and drawn to a large
scale.
a is the work-plate and b is the bar in which a groove c for the needle d is
formed. e is the plate which is fixed to the bar band which serves to prevent the
needle from bending into the path of the shuttle fand so being broken. The

page_text: said plate projects over the groove c to such an extent that the slot or opening
through which the thread passes is out of coincidence with the centre of the
needle. By thus arranging the opening g on one side of the centre of the needle,
not only is the needle prevented from bending into the path of the shuttle but a
more perfect loop is formed than when the said opening is opposite the centre of
the needle, the said loop being thrust somewhat to one side as it passes through
the said slot as shewn in Figure 2 wherein h indicates the thread. The rear side
of the plate e is rounded off as at i so as to facilitate the passage of the thread
through the slot g.
On the upper part of the plate e is a slot or notch k which serves to allow the 1
locked or looped threads to be pulled up to the work.
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 :-
In a sewing machine forming the slot of the needle-groove at one side of the
centre of the needle, substantially as, and for the purpose, described.
