"IMPROVEMENTS IN
THE MANUFACTURE OF STUFF-BUTTONS." [A communication from Wedding and
Schmittmann, of Elberfeld, in the Empire of Germany.]
The Invention has for its object an improved attachment for stuff or cloth buttons,
and consists in making the base of the buttons of a metal casing which projects
over the base of the stuff button in the shape of a short cone with rounded point,
said cone being provided with openings, preferably two in number, placed opposite
each other, and perpendicular to the axis of the cone. The said casing may be
stamped from sheet metal, and in order to prevent any cutting of the threads which
pass through the holes the metal is not formed with a sharp but with a bell mouthed
edge by bending the sheet more or less inside, or otherwise; said mouth may be
lined with cloth, card, or other suitable material. Although a coniform shape is
preferred for the casing forming the shank, the button itself may have any other
suitable shape, and be made of any convenient material.

and Patent Agents, of Magdeburg, in the Empire of Germany. "IMPROVEMENTS IN
-THE-MANUFACTURE-OF-STUFF-BUTTONS."-A-communication-from-Wedding_and_
Schmittmann, of Elberfeld, in the Empire of Germany.
Whilst the back of buttons covered with stuff, and often used for the trimming of
clothes and dresses, is generally made in such a manner that the thread for fastening
the button passes only through a projection consisting of stuff or many threads, this
new back is constructed with a metal cap lined with cloth or other suitable mate-
rial, and provided with two or more openings through which and through the cloth
the sewing thread has to pass, whence a tighter and safer fastening of the button is
produced.
The said back is shown in an enlarged scale on the annexed Drawing, of which
Fig. 1 shows an axial section, Fig. 2 an elevation, and Fig. 3 a back view, whilst
Fig. 4 represents another axial section through the metal cap only.
The metal cap, made in a suitable manner of sheet metal, has the shape of a
truncated cone passing gradually into that of a short cylinder, the inner end of
which is rounded off. The side of the cone is provided with two or more openings a,
and each part b of the side beyond the openings is bent towards the inside in such
a manner as shown in Figs. 3 and 4. In order to prevent a damaging of the sewing
thread by the sharp edges of the metal cap, the latter is covered with cloth or other
suitable material c through which the sewing thread has to pass. The upper part
of the back may be provided with a round disc d made of card or any other suitable
material, thus securing the button against undue deformation.
