IMPROVEMENTS IN BUTTON OR STUD FASTENERS

DI DUIICATION.
I, HERBERT JOHN HADDAN, of the firm of Herbert and Company, Patent
Agents, of 67, Strand, in the City of Westminster, Civil Engineer, do hereby declare
the nature of said invention for IMPROVEMENTS IN BUTTON OR STUD FASTENERS,
a communication to me from abroad by Duke Farnsworke Baxter, of Rochester,
United States, to be as follows:-
The invention relates to that class of buttons, studs, clasps, etc., in which a
threaded stem passed through a fabric is the means of securing thereto a button,
stud or other attachment, and the invention consists in constructing the attachment
so that the stem may be easily passed through the fabric without injury to the
latter.
Heretofore it has been common to make studs in two parts one being the button
and the other a headed screw pin passing through the fabric into the button. It is
not practicable to force the threaded stems of such attachments directly through
heavy fabrics and it is common to 'perforate the latter with a piercer, or to use a
hollow ended needle to facilitate the introduction of the stem.
To avoid the use of these secondary appliances which tear and otherwise injure
the fabric, and which cannot sometimes be obtained, I make the stem with the
usual cylindrical body having a screw thread adapted to that in the body of the
button or other device, and extend the stem beyond the body to form a tapering
end which may be smooth but in which I prefer to form one or more quick
screw threads having a greater pitch than the screw thread upon the body of
the stem.
A stem having a tapering point may be passed through the fabric without the
use of piercers or needles, but has more or less tendency to separate and tear the
finer fibres. If, however, the tapering point has a quick screw thread or a thread
having a comparatively large pitch, it will enter the fabric freely and without
injury threto, so that the position of a stud or button may be repeatedly changed
within a limited space without injury to the fabric.
To facilitate the passage of the screw stem into the fabric I provide said stem
with a head having projecting arms whereby it may be readily turned.

Agents, of 67, Strand, in the City of Westminster, Civil Engineer, do hereby
declare the nature of my invention for IMPROVEMENTS IN BUTTON OR STUD
FASTENERS, a communication to me from abroad by Duke Farnsworke Baxter, of
Rochester, United States, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
The invention relates to that class of buttons, studs, clasps, etc, in which a
threaded stem passed through a fabric is the means of securing thereto a button,
stud or other attachment, and the invention consists in constructing the attach-
ment as fully described hereinafter, so that the stem may be easily passed through
the fabric without injury to the latter.

In the drawing: Fig 1 is a sectional view enlarged showing my attachment as
applied to securing a button to a fabric.
Figs 2 and 3, are external views showing modifications of the screw stud.
Fig 4, is a plan of the stem.
Fig 5, is a section showing the attachment as used in securing the ornamental
pendant of a leather or heavy fabric hanging.
Heretofore it has been common to make studs in two parts, one being the button
and the other headed screw pin passing through the fabric into the button. It is
not practicable to force the threaded stems of such attachments directly through
heavy fabrics and it is common to perforate the latter with a piercer, or to use a
hollow ended needle to facilitate the introduction of the stem.
+
To avoid the use of these secondary appliances which tear and otherwise injure
the fabric, and which cannot sometimes be obtained, I make the stema, with the
usual cylindrical body having a screw thread adapted to that in the body" A,
of the button or other device, and extend the stem beyond the body to form a
tapering end which may be smooth as in Fig 2, but in which. I prefer to form one
or more quick screw threads c, having a greater pitch than the screw thread upon
the body of the stem, Fig 1, showing a termination with two threads and Fig 3,
a termination with a single thread.

.f
A stem having a tapering point may be passed through the fabric without the
use of piercers or needles, but has more or less tendency to separate and tear the
finer fibres. If, however, the tapering point has a quick screw thread or a thread
having a comparatively large pitch, it will enter the fabric freely and without
injury thereto; so that the position of a stud or button may be repeatedly changed
within a limited space without injury to the fabric.
The reason of this will be apparent upon inspecting Fig 4, from which it will be
seen that the cross sectional dimensions of a threaded stem, are much less than
of a solid one; thereby lessening the spread of the fibres where the penetration
occurs.
To facilitate the passage of the screw stem into the fabric I provide said stem
with a head having projecting arms ; whereby it may be readily turned.
Without limiting myself to any special form of stud or button, I declare that
'what I claim is :-
1. A detachable stud provided with a head having a threaded opening and an
attachment consisting of a threaded stem terminating at one end in a head and
at the other in a tapering point, substantially as set forth.

page_text: 2. The combination with a detachable stud or button, of a head having a
threaded opening and a screw pin adapted to said opening, provided with a tapering
end having one or more quick threads, and with a head at the opposite end.
3. The combination of the button or stud and the attachment having a screw
stem and lateral arms at the outer ends, for the purpose set forth.
