Joseph W. Dews, Waterbury, Conn, assigncr to
Scovill Manufacturing Company, a corpora

Application April 13, 1938, Serial No. 291,719
8 Claims. (Cl. 24—-216)
This invention relates to improvements in snap
fastener assemblies of the type comprising com
plemental socket and stud members, and more
particularly to a socket member which is of
5 laundry-proof construction.
The principal object of the invention is to pro
vide a fastener socket member of such strong and
durable construction‘ that it may be affixed to a
garment or other article of a launderable nature
10 without fear that it will be crushed by the heavy
stresses which are normally incurred in the
course of washing and ironing such a garment.
It is another and more speci?c object of the
invention to provide a socket member of the fore
15 going character, having a plurality of somewhat
delicate ?ngers adapted to engage the head of a
complemental stud member, with a shield par
tially overlying and surrounding those ?ngers in
such a way as to protect them from external
stresses without, however, interfering with their
normal functioning.
It is a further object of the invention to pro
vide a socket member'which, in addition to the
foregoing, is arranged for cooperation with a
pronged type of attaching eyelet or cap whereby
it may be securely a?ixed to its supporting sheet.
It is yet another object of the invention to pro
vide a two-piece socket member of this character,
which, because of its extremely simple character,
may be manufactured very inexpensively.
The foregoing and other objects, as well as
various features of the invention, may be more
fully understood from a consideration of the fol
lowing description in the light of the accompany
ing drawing, in which
gaged by the resilient ?ngers of a socket l5, the 10
latter member being constructed and affixed to
its supporting sheet it in accordance with the
teachings of the present invention. In this ?g
ure each of the supporting sheets is shown as
comprising two layers of material which are in- ‘ 15
tended to represent hemmed portions formed
along the overlapping edges of a garment of a
launderable nature.
The socket member i5 is of two-piece construc
tion comprising a resilient socket element ll, as ‘ 20
shown in Figs. 2 and 3, and a cap element 18,
particularly illustrated in Figs. 4 and 5.
The socket element is preferably of one-piece
construction comprising, a central wall of gen
erally cylindrical proportions which has been 25
axially slitted, or notched, at a number of points
59 to form a plurality of resilient ?ngers 2E, and
inwardly rolled along its free front edge to pro
vide each of these ?ngers with a stud engaging
bead ‘2 l ; and an anvil portion 22 turned reversely
from the rear end of the wall and ?ared out
wardly to de?ne a V-shaped trough surrounding
the ?ngers and forwardly to such extent that the
outer extremities of its front surface lie in a
plane which preferably, although not necessarily,
ber engaged by the complemental resilient parts
may best be seen in Figs. 2 and 3. _

The cap is is also of one-piece construction
comprising a sheet metal blank which has been
pressed, drawn and turned to provide it with a
substantially flat shield portion 23 having a cen
tral opening ‘M therein through which the head
of a stud member may be passed, and a rim 25
extending rearwardly from the outer margin of ~ 45
the shield. In the preferred embodiment, as
shown, the opening M is de?ned by the inner
surface of a cylindrical lip 26, the latter part
being drawn rearwardly from the inner margin
of the shield portion and having an inside diam 50
eter which slightly exceeds the outside diameter
of the cylindrical wall de?ned by the resilient
?ngers 20 of the socket element.
The blank from which this cap is made may
have a continuous outer edge, if desired. Pref

an amount suf?cient to permit the ?ngers to
?ex when the head of the stud member passes
therethrough~and thus to prevent the acciden
tal insertion of any object between these two
parts which would tend to bend the prongs in
wardly.
In Figs. 1 and 3 the free ends of the stud en
gaging ?ngers are merely turned over and di
rected inwardly towards the center of that ele
ment. This construction leaves a relatively sharp
bead on the end of each ?nger for cooperation
with the head and neck of the stud element. In
many cases it will be found desirable to turn these
free ends inwardly as shown at Zlot in Fig. 9, even
15 though that may involve an additional turning
or pressing operation, so that the bead will pre
sent a rounded, relatively smooth surface to the
head of the cooperating stud member.
It is apparent from the foregoing that certain
variations in the dimensions of the various parts
of the socket member may be permitted without
destroying its utility. Usually a variation in the
dimension of a part of one element will be met by
a corresponding variation in a complemental part
of the other member. The objects of the inven
tion will, however, be accomplished if the mem
ber is of two-piece construction with the front
surface, and the inner lip, of the cap forming
collectively a shield lying forwardly of, and sur
30 rounding, the somewhat delicate stud-engaging
?ngers, and if the outer ?ange of the cap is spun
inwardly to de?ne a retaining ring, between that
part and the adjacent undersurface of the anvil,
for receiving and retaining the prongs of an at—
taching eyelet or similar attaching device.
Since certain changes may be made without
departing from the true scope of the invention,
it is intended that the foregoing shall be con
strued in a descriptive rather than in a limiting
