PROVISIONAL SPECIFICATION.
Improvements in Embroidering Machines.
We, EMILE CORnely, and Robert Cornely, both of 87 Faubourg St. Denis,
Paris, France, Manufacturer of Sewing Machines, do hereby declare the nature of
this invention to be as follows:-
The present invention relates to improvements in machines for embroidering
stockings, socks and gloves and similar articles, for which purpose the machine is
provided with a cylindrical or other shaped narrow arm or bed plate on which the
hollow articles to be embroidered can be placed.
On the accompanying drawings:-
Fig. 1 represents a vertical section full size through the improved arm and the
mechanism for producing the stitch.
Fig. 2 represents a plan of the same.
Fig. 3 represents a sectional part equally full size of the arm as it has been
constructed heretofore.
Fig. 4 is an enlarged vertical section of the new looper.
The size of the arm as employed heretofore and represented in Fig. 3 could not
be reduced in its dimensions for the reason that the stitch. producing parts of the
machine composed of the screw rack A, the oscillating screw pinion B and its
looper C, which operate in conjunction with the needle hook D, had to be lodged
within said arm of the machine and therefore neither its height abnor its
length c d could be in any way reduced which made it impossible to embroider
gloves and childrens stockings. Therefore in order to obtain an arm of very
reduced size the screw rack A and its screw pinion B have been disposed to the
rear of the arm N of the machine.
The pitinan E drives in the well known manner the lever F, which imparts a
reciprocating motion to the rad G of the screw rack A and an oscillating motion
to the screw pinion B, but the latter instead of being provided with the looper C,
as heretofore and as represented in Fig. 3, is provided with a pinion H which
communicates its motion to pinion I, shaft K and pinions L and M which latter
acts as looper it being provided with proper openings for the passage of the thread
as represented on an enlarged scale at Fig. 4.
As the pinion I, shaft and pinions L and M can be brought within a very
small compass it follows that the size of the arm N can be much reduced, not only
in height and in width but also in its length outside of the needle hole, as shown at
Fig. 1 in full size, by the distance cd which is much shorter than the distance c d
of the old machine (Fig. 3). The operating parts herein described as well as the
needle and the feed are directed by means of the crank handle O, pinions, P, Q,
R, S, T, & U in a similar manner as heretofore but with slight changes in
their arrangement such as required by the new arrangement of the screw
gearings A and B.
The arm N is provided with a slot x (Fig. 1) in which the thread passes as it
goes from the bobbin to the looper.
Dated this 22nd day of April 1893.

We, EMILE CORNELY and ROBERT CORNELY, both of 87 Faubourg St. Denis,
Paris, France, Manufacturers of Sewing Machines, 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 :-
The present invention relates to improvements in machines for embroidering
stockings, socks and gloves and similar articles, for which purpose the machine is
provided with a cylindrical or other shaped narrow arm or bed plate on which the
hollow articles to be embroidered can be placed.
On the accompanying drawings
-
Figure 1 represents a vertical section full size through the improved arm and
the mechanism for producing the stitch.
Figure 2 represents a plan of the same.
Figure 3 represents a sectional part equally full size of the arm as it has been
constructed heretofore.
Figure 4 is an enlarged vertical section of the new looper.
The size of the arm as employed heretofore and represented in Figure 3 could
not be reduced in its dimensions for the reason that the stitch producing parts of
the machine composed of the screw rack A, the oscillating screw pinion B, and its
looper C, which operate in conjunction with needle-hook D, had to be lodged within
said arm of the machine and therefore neither its height a 6 nor its length cd could
be in any way reduced, which made it impossible to embroider gloves and children's
stockings. Therefore in order to obtain an arm of very reduced size the screw
rack A and its screw pinion B have been disposed to the rear of the arm N of the
machine.
The pitman E drives in the well-known manner the lever F which imparts a
reciprocating motion to the rod G of the screw rack A, and an oscillating motion
to the screw pinion B, but the latter instead of being provided with the looper C,
as heretofore and as represented in Figure 3, is provided with a pinion H which
communicates its motion to pinion I, shaft K and pinions L and M, which latter
acts as looper, it being provided with proper openings for the passage of the thread
as represented on an enlarged scale at Figure 4.
As the pinion I, shaft K and pinions L and M can be brought within a very
small compass, it follows that the size of the arm N can be much reduced, not only
in height and in width, but also in its length outside of the needle hole, as shewn
at Figure 1 in full size, by the distance c d which is much shorter than the
distance c d of the old machine (Figure 3). The operating parts herein described
as well as the needle and the feed are directed by means of the crank-handle O,
pinions P, Q, R, S, T and U in a similar manner as heretofore but with slight
changes in their arrangement such as required by the new arrangement of the screw
gearings A and B.
The arm N is provided with a slot a (Figure 1) in which the thread passes as it
goes from the bobbin to the looper.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
1. The arrangement of a pinion M within the hollow arm N acting as a looper
in conjunction with a book needle for the production of the seam, substantially as
and for the purposes described and shewn upon accompanying drawings.
2. The arrangement of the screw gears A and B to the rear of the arm N of the

page_text: machine, for the purpose of operating the looper pinion M substantially
described.
