COMPLETE SPECIFICATION.
Improvements in Two-Part Separable Buttons.
We, THE AMERICAN FASTENER COMPANY, of Baltimore City, a corporation duly
incorporated under the laws of the State of Maryland, of 2003 Eutaw Place, in the
City of Baltimore, State of Maryland, and United States of America, and ORMSBY
LYMAN MAHON, of 1405, Linden Avenue, in the same City and State, Salesman,
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 :-
This invention relates to improvements in two-part separable buttons.-Buttons of
this class comprise a socket-member and a stud-member, and are used as glove-
fasteners and for various other purposes.
The object of this invention is to provide a superior button which shall at the
same time comprise few parts, be of simple construction, and capable of manufacture
at low cost.
The invention is illustrated in the accompanying drawing in which,-
Figure 1 is a sectional view of a cap and a separate enclose ring in position to be
secured together, the same constituting parts of the socket-member.
Figure 2 is a sectional view of the closed-end socket-eyelet.
Figure 3 is a sectional view of the improved socket-member complete secured to
the fabric.
Figure 4 shows two views of the flat circular blank from which the spring-stud is
formed.
Figure 5 is a side view showing the first formation of the spring-stud.
Figure 6 is a side view of the eyelet which secures the stud to the fabric.
Figure 7 is a sectional view of the improved spring-stud member complete, secured
to the fabric.
Figure 8 shows a section view of the socket and a side view of the spring-stud
engaged together.
The letter, A, designates the socket-eyelet having a closed end which, before
attachment to the cap has a rounded peak, as at, b, Figure 2; this socket has a
flange, c, and a slightly-contracted entrance, d. It will be understood the interior of
this closed-end eyelet is to constitute the socket-chamber to receive the "stud
member" of the button.
The cap, F, has a top surface, e, and a ring is enclosed and clamped in the cap by
an outer flange, J. This ring is approximately U-shaped in cross-section, having an
outer circular wall, h, then an inturned annular surface, i, which bears on the fabric, j,
and an internal rim forming a sleeve, k, which projects upward towards the said top
surface of the cap but leaving an open space between the top-edge of the sleeve and
the interior top surface, e, of the cap. When these parts are secured together on the
fabric as seen in Figure 3, the upper part of the closed-end eyelet is bulged, as at, l,
over the top-edge of the sleeve and thereby produces an engagement of the two parts.
This is effected as follows: The closed end of the tubular eyelet is forced through a
hole in the fabric, j, until its flange, c, comes in contact with the fabric on one side-
the closed-end projecting on the opposite side. The cap, F, then has its sleeve, k,

page_text: slipped over the said tubular eyelet until the closed-end, b, contacts with the said
interior top surface of the cap; the effect of die-pressure now brought to bear on the
cap, F, and closed-end of the eyelet will be to bulge or expand the crown of the eyelet,
the said bulged part, l, projecting over the top-edge of the sleeve, k, and locking the
parts together on the fabric, j; and the further effect is to simultaneously bring the
annular bearing surface, i, in close contact with the fabric.
The spring-stud, L, is made from a disk shown in Figure 4; it is dome-shaped and
has spring-bows, m, which at their base are united with a collar, n, and a ring-
shaped flange, o. The said spring, dome, collar and flange are integral, being
stamped up from the single piece of metal shown in Figure 4.
Slots or spaces, P,
separate the spring-bows. The spring-stud is secured to the fabric, q, as in Figure 7,
by a shank or eyelet, R. This eyelet has a flange, 8. These two parts comprise the
complete spring-stud, and in order to unite them to the fabric, the tube part of
the eyelet, R, is first passed through a hole in the fabric and then into the dome of
the stud, L; then the base-collar, n, of the stud is contracted as at, n¹, by suitable
means so as to make a surrounding indentation into the wall of the shank or
eyelet, R, as shown in Figure 7; and thereby secure the stud on the eyelet; it will
be seen the fabric, q, is compressed or clamped between the flange, o, of the stud and
the flange, 8, of the eyelet.
It will be understood that when the socket-member is forced over the stud-
member to button the parts, the spring-bows of the latter will yield slightly in order
to enter the contracted entrance, d, of the socket, and in like manner when
unbuttoning the parts the spring-bows will yield slightly.
Having now 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. A socket-member of a separable button comprising a cap having a top surface,
an outer circular wall, and an internal sleeve projecting toward said top surface; and
a socket-eyelet projecting into said internal sleeve and having a flange, c, a contracted
entrance, d, and a flattened closed-end, which is bulged or expanded, as at, l, over
the edge of the said internal sleeve, as set forth.
2.
A spring-stud of a separable button comprising a shank having a flange; and
a dome-shell having spring-bows, a flange, o, a collar, n, uniting the spring-bows and
Hange the bows, flange and collar all being integral-and said collar being con-
tracted to pinch or grip the wall of the shank and thus secure the shank and spring-
dome together on the fabric, as set forth.
3. A spring-stud of a separable button comprising a shank having a flange; and
a dome-shell having spring-bows separated by slots and contracted or pressed inward
to grip the wall of the shank and thereby secure the spring-dome on the shank.
