half of the fastener as is the case in several well known forms of fasteners. The
improvements relate to advantageous changes in the construction and combination
of such fasteners and to improved modes of application whereby the laps or edges
connected by the fasteners are brought more closely together.
The accompanying drawings clearly represent my invention.
Fig. 1 is a vertical section of a complete fastener applied to overlapping pieces
of material a and b which might represent the overlapping edges of a glove for
example.
Fig. 2 is a horizontal section of Fig. 1 at the line a.
Fig. 3 is a vertical section of the upper half of the fastener.
Fig. 4 is a similar view of the under half.
Figs. 5 and 6 are sections of the upper half of a fastener (distinguished from
each other by slight modifications) and shown applied to a glove already fashioned
with button holes.
Fig. 7 is a vertical section of a fastener by which the upper overlapping edge of
the glove is brought closer down to the under edge.
Figs. 8, 9, 10, 11 and 12 represent modifications of the same formation of
fastener.
Referring to Figs. 1 to 4, the under lap of the glove is marked a and the
overlap b. The top of the recessed or female half of the fastener is composed of a
sheet metal foundation m having a decorative or other facing o to give suitable
finish and appearance to the fastener. The foundation m is clamped down upon
the bent upper edge of the central thimble h which stands up from the disc g.
Above the disc g is another disc 1 the circumference of which is turned over so as
to slip well over and confine the up-turned edge g¹ of the disc g. The edge of the
glove or material b is placed between the disc and the foundation and the
thimble is thus clamped to the foundation thus holding the whole of the upper
half of the fastener securely together and attaching it firmly to the glove leather b.
Just above the disc g 1 form two slits in the thimble h, these slits lying parallel to
each other. I next place two pieces of tempered steel wire d d which lie quite
across the disc g and against the up turned circumference g. When placed loosely
in their position and closed up by the applying of the fastener to the leather b,
these wires would show within the thimble has two spring catches, like two chords
of the circle of the thimble. The loose wires d d lying across the disc g and cutting
When the
into the circumference of the thimble h are clearly shown in Fig. 2.
fastener is closed up, these wires cannot leave their position. The under half of
the fastener is shown separately at Fig. 4. The knob k is formed with a flanged
disc q as shown and its hollow prolongations is clenched upon the washer disc p in
the act of securing the knob to the leather a all as clearly shown in Fig. 4. The
knob k is undercut with a groove as shown in the drawings, and the head of the knob
loosely fits the thimble. It will now be clearly seen that if the head of the

page_text: knob is pressed into the thimble h the side wires d d will first be pushed aside
and will then snap back into the undercut groove in the knob, thus holding the
knob in the thimble and consequently securing the part a to the part b. A slight
amount of force suffices to disconnect the halves of the fastener.
In attaching my improved fasteners to gloves in which button holes have already
been formed, as in Fig. 5 the disc may lie close to instead of apart from the disco
as clearly shown in the fig. and the upturned edge of the disc g is formed with
teeth t which pass through and are clenched down upon the material b. This
assists to support the material (already weakened by the button holing) against the
strain of the fastener; otherwise the fastener is secured together and to the
material in the manner already described with reference to Fig. 1. This form of
fastener is fitted with the wires d d and is otherwise fashioned as in the former
instance.
In Fig. 6 the only difference as compared with Fig. 5 is that the disc is in the
same position relatively to the disc g as in Fig. 1 and the clenching teeth t instead
of being on the disc g project from the disc l.
Fig. 7 illustrates the modification I employ to bring the over- and under-lapping
parts or edges and b of the glove more closely together. This is achieved by
bending down the circumference of the top m and also the circumference u of the
disc thus causing the material to dip down and so be brought closer to the
part a. The disc g and other parts already particularised appear in the con-
struction, which presents no material difference except in this dipping downwards
of the circumference of the parts m and l.
In Fig. 8 the disc is beneath the disc g instead of above it as in Fig. 7.. The
edge u of the disc is consequently turned upwards and inwards as shown so as
to present the downward incline to the material b. Otherwise it is the same as
Fig. 7. Fig. 9 is practically the same as the upper half of Fig. 8.
In this view the wires d d are shown lying across the disc g. Fig. 10 is a section
of Fig. 9 at the line yy. Figs. 11 and 12 illustrate the construction of a fastener
having the same object as the three foregoing examples viz. the bringing together
of the over- and under-lapping parts or edges a and b. The construction is similar
to Figs. 8 and 9 but this example is shown with an outer ornamental or other cover.
The upper part of the thimble (see Fig. 12) is clenched between the cone v and
the curved part which is held in place by the clenched up lining r¹.
This method of so making the fastener as to bring the upper edge or lap of the
material or article close down upon the under edge or lap may be employed either
in the construction of fasteners with spring wires as herein before described or in
other classes of fasteners to which the improvement is applicable.
The mere methods of fashioning and clenching together the parts composing
the fasteners hereinbefore described and are not per se new, but the employment of
the spring wires applied and operating in the manner described and the formation
of the parts of the fastener so as to bring the overlapping flaps or edges of the
glove or other article closer together, are new and form salient parts of my present
improvements.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
1. The improved construction of fastener provided with wires d d placed loosely
in the upper part of the fastener, and passing through slits in the recess or thimble h
which receives the undercut or grooved knob k so that when the said knob is
pushed into the thimble the wires spring into the undercut or groove and thus hold
the knob in the thimble, and prevent the balves of the fastener from being dis-
engaged substantially as described and as illustrated.
2. In the construction of fasteners of the indicated or of cognate types so forming
the fastener as to cause the upper and under laps or edges of the glove or other

page_text: article to lie closely together substantially as described and as illustrated in
Figs. 7 to 12 of the drawings.
3. The general arrangement construction and combination of the different forms
of fasteners herein before described and as shown in the drawings.
