Improvements in Spring Buttons.
I, ACHILLE FRANÇOIS RAYMOND, of Grenoble, Isère, France, Manufacturer, do
hereby declare the nature of this invention to be as follows:-
My invention relates to fasteners each in the form of a hollow shell fixed on
the leather or fabric at one edge of the opening in a glove, garment or the like
without making any hole through the leather or fabric, this shell receiving in
its hollow the spring button which is fixed on the other edge of the opening.
For this purpose a thin metal shell of flat hemispheroidal form with its lip
turned inwards and upwards, has the leather or fabric placed over it and also a
metal ring outside the leather or fabric. Also an eyelet is placed in such a
position that its tubular part which is somewhat bent outwards enters the hollow
of the shell. Then by means of a suitable punch and die the whole is crushed
down causing the lips of the shell to turn farther inwards and the edge of the
eyelet tube to expand over these lips, and at the same time forcing down the
external washer and bulging the side of the shell over it, thus firmly holding it
and the leather or fabric over the shell.
Instead of making the shell with its lip turned inwards, it may be turned out-
wards to be held by the flange of the eyelet being turned over the lip, and the
tube of the eyelet may have three or four parts of its circumference cut away
leaving upwardly projecting elastic parts to engage the bulge of the inserted
button which in this case does not require to be of spring kind.
The leather or fabric over the shell may be covered by a cap of like form hav-
ing a turned in edge which when the whole is crushed down is engaged under
the bulge of the inner shell, and serves instead of the washer, which in this
case is dispensed with, to hold the leather or fabric firmly on the inner shell.
For effecting the crushing action described, a special punch and die are re-
quired; the ring is placed on the edge of a tubular die over which the leather
or fabric is stretched, while the shell is placed on the punch. By the descent of
the punch, the shell along with the leather or fabric over the ring is forced into
the ring and the hollow of the die, and moulded on the bottom of the die which
is supported by a spring.

ing statement:-

My invention relates to fastenings each in the form of a hollow shell fixed on
the leather or fabric at one edge of the opening in a glove, garment or the like
without making any hole through the leather or fabric, this shell receiving in
its hollow the spring button which is fixed on the other edge of the opening.
For this purpose I construct the button and fastener as I shall describe
referring to the accompanying drawings.
Fig. 1 is a section of the button fastening in course of construction.
Fig. 2 is a section of the completed fastening.
Fig. 3 shews the fastening in position with button in it.
Fig. 4 shews a modification of the fastening.
Fig. 5 shews another modification.
Fig. 6 shews a fastening with internal claws in course of construction.
Fig. 7 shews the fastening in position.
Fig. 8 is a plan of Fig. 7 looking from below.
Fig. 9 shews another mode of fixing the fastening.
Fig. 10 shews this fastening in position.
Fig. 11 shews the button for this fastening.
Fig. 12 shews another form of button.
Before
Fig. 13 shews a tool for fixing the fastening, its finished form being obtained
while it is being fixed on the skin, fabric or other surface to which it is applied.
The fastening consists of a metallic shell a into which is to enter expanding
and forming as it were an internal rivet, an eyelet having flange c.
inserting the eyelet b a washer y of V section and a curved washer z are inserted
in the shell . The lining tie, ribbon or fabric lines the under side of the
skin e of a glove for instance. This skin e is placed over the shell a and on it a
metal ring f as shewn in Fig. 1. The fastening thus arranged is placed upon an
anvil g and the die is caused to descend, its lower edge bearing on the ring f
forces it down on the skin e, and while all the parts come together as shewn in
Fig. 3, the ring f forces the skin e close to the lining d and the eyelet b expands
inside the shell a. At the same time this shell covered by the skin e of the glove
is flattened between the die h and the anvil y causing its upper part to bulge
outwards so that the ring f which originally passed freely over the shell a, is
now imprisoned under the overhanging part of the fastening as shewn in Fig. 2.
Under these conditions the fastening is firmly fixed on the glove without
piercing the skin which covers the shell of the fastening. The fastening is
ready to receive the button x (Fig. 3) which is sufficiently elastic to be pushed
into the shell of the fastening and yet, once it is introduced has sufficient hold
to keep the two parts of the glove firmly held together.
Instead of employing the system of outwardly expanded eyelet rivet b as in Figs.
1, 2, 3, I can, as shewn in Fig. 4 fix a ring f around the shell a covered with skin e
by the descent of a die which flattens the shell a and consequently causes an
expansion of the shell so as to hold the ring f under the overhanging part thus
formed at the base of the shell.
A fastening capable of holding the button more firmly and at the same time
with more elasticity may be obtained by arranging at its base a washer with
raised inner edge the edge of its flange j being bent over the flange of the
shell a so as to be imprisoned between this edge and the fabric and lining
of the glove or other article.
The washer i applied at the base of the shell a, may have the part inside
notched so as to form projecting claws k. Fig. 6 shews the fastener while it is
being fixed, and in Figs. 7 and 8 it is shewn fixed and having finished claws k
at least three in number, to serve as elastic holders of the button which is intro-
duced within it.
When it is not desired to let the skin or fabric e of the glove appear on the
fastening, a cap 7 Fig. 9, with an inwardly bent edge all round may be used to

page_text: cover the fastening. By action of the die, the cap 7 is made to descend, its edge
pressing the skin e against the shell a which being flattened expands at its
upper part, and as shewn in Fig. 10 fills the interior of the cap 1. The skin is
thus very firmly held, without any hole being made, between the shell a and
the cap
1.
The button to be introduced into the fastening instead of being a slit cap as
shewn in Fig. 3 may be simply formed as in Fig. 11 with a flange m having a
raised edge n an eyelet having one part o engaged in the fold of n and fixed by
rivetting at p on the skin e lined with fabric d.
Fig. 12 shews another way of fixing the button by means of an interior shell
which is swelled out and holds the lined skin de between its flanger and the
flanges of the button.
Fig. 13 shews how the fastening may be fixed with the skin appearing over it.
The diet has an internal core supported on a spring and on this core which has
a concave top is placed the ring f (Fig. 1), then the skin, lined or not, is placed
over the diet. The shell a with its eyelet b is held on the projection u of the
punch which is forced down. Thus is effected the operation explained above in
reference to Figs. 1 and 2, the ring f becoming firmly fixed around the shell
of the fastening and fixing the fastening on the skin of the glove.
Although in the above description I have treated lined skin such as is used
for gloves, as the material to which the button and fastening are applied, ob-
viously they may be applied to fabrics of various kinds that can yield sufficiently
to stretch over the body of the fastening.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. A fastening for a spring button having its shell covered by the skin or
fabric on which it is fixed and secured by an external ring and an internal eye-
let, substantially as described with reference to Figs. 1, 2 and 3.
2. The modified fastening in which the eyelet is dispensed with substantially
as described with reference to Fig. 4.
3. The modified fastening having its internal eyelet formed with claws to
hold a button, substantially as described with reference to Figs. 6, 7 and 8.
4. The modified fastening having the skin or fabric covered by a cap sub-
stantially as described with reference to Figs. 9 and 10.
5. For fastenings such as are referred to in Claim 3 and 4, buttons made
without splits and fixed substantially as described with reference to Figs. 11
and 12.
6. For fixing fastenings of the kind referred to in Claim 1 a tool arranged and
operating substantially as described with reference to Fig. 13.
