COMPLETE SPECIFICATION.
Improvements in Button Hole Guards and in Machinery therefor.
We MORITZ WILLIAM GEORG PROLSS and MAX MAYER, Manufacturers of
12 Johannis-strasse Dresden in the Kingdom of Saxony and German Empire do
hereby declare the nature of our said invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:—
The object of this invention is to provide button holes with a guard whereby the
same are protected and preserved from being torn open and consists of a half eyelet
made of metal and of a shape to correspond with the wide end or corner.of the
button hole and is fixed to the inner edge of the said corner where the button rubs
against the button hole. This half eyelet can be fixed to the button hole by
sewing or by pressure or by pressure and sewing combined.
On the accompanying drawings
Figs. 1 to 5 illustrate several methods of forming stamped eyelet plates. In
these figures the small eyelet plates are furnished at their longitudinal sides with
one or more points e.
Fig. 6 is a front view of the eyelet plate shewn in Fig. 1 after stamping Figs. 7
and 8 being a corresponding plan and side views respectively.
Fig. 9 is a cross section of the die which is used to stamp the eyelet plates into
half eyelets.
Fig. 10 shows an under side view of the matrix.
Fig. 11 is a plan of the parts of the press with the eyelet in position. The
plates d serve to hold the eyelet while being stamped.
Fig. 12 is a side view of the die.
Fig. 13 shows a section of the press by means of which the stamped half eyelet
is fixed to the button hole.
Fig. 14 is an under side view of the head of the press shewn in Fig. 13.
Fig. 15 is a plan of the foot of the press.
Fig. 16 shows another arrangement of the press that is to say with a matrix
operating concentrically.
Figs. 17 to 20 show front views of various methods of fixing the half eyelet to
the button hole and corresponding cross sections.
In Fig. 17 the half eyelet engages with its teeth e in the purling seam of the
button hole.
Fig. 18 shows a half eyelet provided with holes g by means of which the said
half eyelet is fixed by stitching to both sides of the button hole.
Fig. 19 shows a half eyelet fixed to the material by means of points. These
points are not inserted firmly in the material when the half eyelet is fixed like
the above mentioned points e but they are beaten or pressed out of the metal plate
into the material. In this manner the half eyelets are very firmly secured in
position.
Fig. 20 shows a half eyelet furnished with holes y through which the said half
eyelet is in this case sewn to the material on one side only of the button hole.
h
The fixing of the half eyelet by means of the small press shewn in Figs. 13 or 16
is effected in the following manner. The half eyelet is loosely fixed upon the
required part of the button hole when the round part of the button hole is pushed
with the half eyelet loosely connected thereto over the pin k so that the half eyelet
comes to rest in the recess a whereupon the half eyelet is pressed between a and b
against the button hole.
The half eyelets may be bent at their shorter sides so as to impart an ornamental

page_text: appearance thereto as well as to facilitate their fixing and insertion in the
button hole.
Having thus particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. Button hole guards consisting of a stamped metal fitting, preferably of a
sidewise bent half eyelet which is furnished with one or more points whereby it can
be inserted or firmly pressed in the material substantially as hereinbefore described
and illustrated on the accompanying drawing.
2. For firmly attaching or pressing the button hole guard the use of a small
press in which the matrix may operate concentrically as well as excentrically after
the round part of the button hole is drawn with the half eyelet already loosely
connected thereto over the pin substantially as hereinbefore. described and
illustrated on the accompanying drawing.
