Improvements in Busks for Corset-fastening.
...
I, HERMANN THEIS, of Ohligs, Rhenish Prussia, Germany, Manufactory-
manager, 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 busks or corset-steels for corset-fastening and it has
for its object to render the fastening a safe one against spontaneously unling by
itself, to reduce its weight in comparison to the hitherto usual forms of busks.for
fastening corsets, of which those with buttons or studs on one part and eyes or
button holes on the other part are subjected to spontaneous undoing by the
movements of the human body. The arrangement of busks of my invention
obviates successfully this defect by retaining the approved form with straight
edges facing each other and having rivetted along one of them a row of little
lugs with eyes in them, and little buttons or studs rivetted to. the other one for
introducing them into the corresponding eyes, these busks however have the
drawback that they get rather heavy on account of the great width required for
them and the additional weight of the extra fixed lngs.
My invention consists in making the busks with the lugs for the eyes in one
piece of sheet-steel, having the eyes and studs arranged either in regular or
irregular alternation on the two parts of the busks or steels and in punching
the eyes into the lugs projecting somewhat at the straight edge of the busk.
These new and improved busks for fastening the corsets are shown in the
accompanying drawing in.which:
Fig. 1 shows the separate busks with alternating studs and eyes and the lugs and
eyes made in one piece with the busk.
Fig 2. the same in jointed,state,

Fig. 3. a pair of separated busks with studs on one and lugs and eyes on the
other part.
Fig. 4. shows a pair of jointed busks with irregularly alternating lugs and studs
on each.

Fig. 5. shows in front-view and cross-section part of a busk with lug and eye
in enlarged scale,
Fig. 6 is a pair of separated busks with separately made lugs and studs in
regular alternation, the lugs rivetted to the busks or steels.
The busks or corset-steels A and B are punched out of a sheet of steal so
that the lugs C. project on each of them just so much over the straight edges
facing each other, as is necessary for being able to put the eyes D in the lugs
over the studs E, which, latter are rivetted as usual, to the busks, so that when
both are fastened together and then pulled asunder in the direction of the plane
of the steels, the narrow parts of the eyes marked F may slide under the heads
of the studs E, and the straight parts of the edges facing each other leave only
a narrow slit between them, so that they make a close fit, when covered with
the corset-stuff; as seen in Fig. 2. It will be seen that in this way in one, say
the lowest set of fasteners the lug of the left hand busk covers the right hand
busk, and at the next fasteners higher up, the lug of the right hand busk
covers that on left side; the arrangement Fig. 3 is a variation hereof, the
busk B only having a row of studs E and the busk A' having only the lugs
and eyes C, the latter ones covering therefore with their projecting parts the
huel RI

page_text: The arrangement with alternately arranged studs and eyes is the preferable one.
The same preference may be given to the arrangement Fig. 4 where an irregular
distribution of the studs and eyes is giving the saine safety as that shown in Fig. 2.
In these three variations of the improved busks of my invention the essential
feature is, that the projecting lugs of each busk are made in one piece with the
busk itself. By this it is possible to reduce the width and the weight of the busks
or corset-steels to a minimum without weakening the material because rivet-holes,
for rivetting separately made lugs with eyes to the busks are avoided.
Comparing these three modifications of corset steels or busks to a fourth one,
which is represented in Fig. 6, where such separately made lugs with eyes are
shown rivetted to the busks in regular alternation of eyes and studs, as was shown
in Fig. 1, it will be easily understood how much the total width of the latter is
reduced, in paying attention to the distance which the rivetted lugs of Fig. 6 must
project beyond the straight edge of the steels, because the round hole in it must be
clear of this edge while, as shown clearly in Fig. 5, the round hole D, when lug
and busk are made in one piece, stands considerably behind the straight line of
contact of the two parts of busks.
The projecting part of the lugs made in one piece with the busks may be set off
so that the busks proper, when in closed state, are in one plane and the lugs are
standing over it; but it is obvious, that the slight torsion of the steels with
alternate lugs and studs, when closed together without offsets in the lugs, gives
them a greater safety against spontaneous undoing, because the studs are pressed
tightly against the narrow part of the eyes F by the spring power of the then
slightly tortuous busks.
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:
1. In busks for corset fastenings arranging the fastening lugs and eyes alter-
nating with the corresponding studs or knobs, on both blades of a fastening set, in
regular or in irregular order.
2. Busks for corset fastenings having the lugs and eyes punched out of one piece
of steel with the blade instead of fixing them separately, such busks having the
lugs and eyes either all arranged on one blade of a set only and the corresponding
studs on the other blade, or, having the lugs and eyes arranged on both blades
alternating with the studs in regular or irregular order, as illustrated and for the
purpose set forth.
