A NEW METHOD OF FIXING BUTTONS, KNOBS, ORNAMENTS, AND OTHER LIKE ARTICLES
Year: 1877

page_text: LETTERS PATENT to Amédée Combault, of 24, Broad Street, Golden Square,
in the County of Middlesex, Jeweller, for the Invention of "A NEW METHOD
OF FIXING BUTTONS, KNOBS, ORNAMENTS, AND OTHER LIKE ARTICLES.”
PROVISIONAL SPECIFICATION left by the said Amédée Combault at the
Office of the Commissioners of Patents on the 15th March 1877.
AMÉDÉE COMBAULT, of 24, Broad Street, Golden Square, in the County of
Middlesex, Jeweller. "A NEW METHOD OF FIXING BUTTONS, KNOBS, ORNAMENTS,
AND OTHER LIKE ARTICLES."
From the centre of the under side of the disc or knob of a metal or other button
a short shank or pin projects, terminating in a narrowed neck and small head or
knob. The length of the shank depends on the thickness of the material to which
the button is to be affixed, and should (exclusively of the neck and head) be only
just sufficient to traverse such material. The shank being forced through the
material, over the small knob at its end, and on the reverse side of the material, I
press a small disc of thin metal (by preference, watch spring or leaf steel) or other
suitable material, perforated in its centre with a small hole of somewhat less
diameter than that of the shank, and with radiating slits from its centre to within
a short distance of its circumference. This steel disc must be slightly convexed,
the concave side being pressed over the small head or knob of the shank. The
elasticity of the steel causes the points or angles presented by the radiating slits in
the steel disc, when they have passed over the small head or knob at the end of the
shank, to converge round the neck beneath the head or knob the button is then
irremoveably fixed, the more it is pulled the greater being the resistance offered by
the converging and slightly convexed points or angles, which cannot repass over the
head or knob.
Another mode of employing the system consists in fixing the perforated disc on
or in the under side of the button itself, with the concave side downwards, in which
case a plain disc and shank, with neck and head such as already described, is made
to traverse the inaterial to which the button, is to be affixed from the reverse side,
and enter the perforated disc fixed on or in the under side of the button.

page_text: The system is applicable not only to buttons ordinarily so called, but to metal or
wooden knobs of drawers, doors, &c., and to metal and other ornaments, and all
articles which are now attached by means of rivets, screws, &c.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said Amédée Combault in the Great Seal Patent Office on the 14th September
1877.

Middlesex, Jeweller. "A NEW METHOD OF FIXING BUTTONS, KNOBS, ORNAMENTS,

The
From the centre of the under side of the disc or knob (A, Drawing 1) of a metal
or other button a short shank or pin (B) projects, terminating in a narrowed
neck (F) and small head or knob (C). The length of the shank depends on the
thickness of the material to which the button is to be affixed, and should (exclusively
of the neck and head) be only just sufficient to traverse such material.
shank (B) being forced through the material (E), over the small knob (C) at its end
and on the reverse side of the material I press a small disc (D) of thin metal (by
preference, watch spring or leaf steel) or other suitable substance, perforated in its
centre with a small hole of somewhat less diameter than that of the shank, and
with radiating slits from its centre to within a short distance of its circumference
(D, Figures 6 and 7, Drawing 1). This steel disc must be slightly convexed
(D, Figure 7, Drawing 1), the concave side being pressed over the small head or
knob of the shank (Figures 3 and 4, Drawing 1). The elasticity of the disc causes
the points or angles presented by its radiating slits, when they have passed over the
small head or knob at the end of the shank, to converge round the neck beneath the
head or knob; the button is then irremoveably fixed, the more it is pulled
the greater being the resistance offered by the converging and slightly convexed
points or angles, which cannot repass over the head or knob.
Another mode of employing the system consists in fixing the perforated disc on
or in the under side of the button itself, with the concave side downwards
(Drawing 2); in which case a plain disc and shank (Figure 5, Drawing 2), with
neck and head such as already described, is made to traverse the material
(E, Drawing 2), to which the button is to be affixed from the reverse side, and enter
the perforated disc (Figure 7, Drawing 2) fixed on or in the under side of the
button.
The system is applicable not only to buttons ordinarily so called, but to metal or
wooden knobs of drawers, doors, &c., and to metal and other ornaments, and all
articles which are now attached by means of rivets, screws, &c.
In witness whereof, I, the said Amédée Combault, have hereunto set my
hand and seal, this Thirteenth day of September, in the year of our Lord
1077
