1 Claim.
This invention relates to connection devices
for attachment to various articles and more par
ticularly to those formed of plastic material such
as clasps, buckles and the like and especially for
5 use with such articles formed of catalin and cel
One of the principal objects of the invention
is to provide attachments for use with such ar
ticles having improved means for securing them
10 to the same.
Another object is to provide a clasp
member which has a base portion of suitable ma
terial, and attachments secured thereto, one of
which is adapted to have one end of a belt per
manently attached to it, and another being a con
15 nection member, such as one having a hook or
one having an eye or slot to be engaged by a
hook, or other suitable devices adapted to engage
for connecting the ends of a belt, said attach
ments being provided with my improved means
20 for attaching them to the base portion. A fur
ther object is to provide a metallic attachment
to which a piece of plastic material such as cel
luloid or catalin is secured and which can be ap
plied to a clasp or buckle base by cementing or
_ pasting it thereto or other suitable manner.
The means I prefer to employ for accomplish
ing the above objects, together with other ad
vantageous and novel features of my invention,
are illustrated in the drawing accompanying and
forming part of this speci?cation, and in Which
Figure 1 is a rear elevation of a clasp employ
ing my improved attachments.
a side elevation of the same.
a. front elevation of the same.
a plan of the same.
a side elevation of one form of my
improved attachments.
Fig. 6 is a rear elevation of the same.
Fig. 7 is a section of the same taken on the
line 1-1 of Fig. 6.
Fig. 8 is a, side elevation of another form of
my attachments.
Fig. 9 is a plan of the rear of the same.
Fig. 10 is an elevation as seen from the right
of Fig. 9.
Fig. 11 is a side elevation of another form of
my attachments.
Fig. 12 is a plan of the rear thereof.
Fig. 13 is an elevation as seen from the right
of Fig. 11.
Fig. 14 is a rear elevation of another form of
my attachments, and
Fig. 15 is a side elevation of the same.
Referring to Figs. 1 to 4 inclusive of the draw
ing, the numeral 2 indicates the base portion of
an article to be supplied with attachments, in
this instance being a clasp for a belt, 3 indicates
one of the attachments, and 4 indicates another
(01. 24--226)
of the attachments. The attachment 3 is illus
trated on a larger scale in Figs. 5, 6, and 7, and
consists of a raised elongated portion or bar 5,
end portions 6, and juncture portions ‘I joined to
the end portions. The juncture portions 1 have
perforations 8 and attached to the edges of the
perforations 8 are prongs or points 9.
Attached to the portions 6 are parts ID, in this
case said parts being thin rectangular pieces of
plastic material such as catalin or celluloid, which 1O
parts are held against the faces ll of the junc
ture portions '1, the prongs or points 9 being
forced through or into the parts I 9 and their
ends forced outwardly so as to be well embedded
in said parts l0, and to hold the same securely
against the juncture portions 1. The portions
5 are attached to the parts In and the latter cut
to size all in one operation of a press. The at
tachments 3 are adapted to have ?exible mate
rial such as a belt attached to them as by looping
it around said bars 5.
Figs. 8, 9, and 10 illustrate the attachment 4,
which has a hook l4 and a body portion l5 pro
vided with perforations 8 and prongs 9. There
are parts ll? of plastic material held against the
juncture faces l6 of the body portions l5 by
means of the clinched prongs 9 embedded in or
forced through them.
Figs. 11, 12, and 13 show another form of at
tachment which is indicated by I1 and consists
of a body portion l8 and a front extension I9 3O
having a slot 20 suitable for engaging with a book.
The body portion has perforations 8 and prongs
9, and there are parts IU of plastic material se
cured by the prongs 9 embedded in them, to the
body portion I8.
Figs. 14 and 15 show a modi?ed form of the
attachment 3 and in said ?gures 21 indicates the
elongated bar, 22 the bent end parts, and 23 the
juncture portions. To the latter are applied the 40
parts !9 of plastic material by the prongs 9 em
bedded in them.
What I claim is:
In a clasp comprising a base portion made of
celluloid and a coupling element secured to one
of the ends of said base portion, means adhered
to said base portion for anchoring the loop of a
belt to said base portion, said means comprising
a longitudinal ?at metal strip terminating at
each of its ends in a ?at tab offset from and par 50
allel to said main body member; a celluloid fac
ing covering the outside surface of each of said
tabs and adhered to said base portion; and a
plurality of prongs struck out of each of said tabs
and extending into the celluloid facing immedi 55
ately adjacent thereto for attaching said cellu
loid facings to said tabs.
