PROVISIONAL SPECIFICATION left by the said Amedee Combault and
William Thomas Taylor at the Office of the Commissioners of Patents on
the 4th August 1882.
AMEDEE COMBAULT of 226 Regent Street in the County of Middlesex Manu-
facturers Agent and WILLIAM THOMAS TAYLOR of 20 Westbourne Terrace Harrow
Road in the County of Middlesex Esquire AN IMPROVED MECHANICAL BUTTON
The button consists of two separate parts, the knob or button proper, and the
shank. The former is composed of or contains two equal circular convexo-concave
discs of thin steel or other suitable material. In the centre of one of these discs
(to be placed under the other on its concave side) is a perforation sufficiently large
to admit the easy passage of the shank-head hereinafter described In the centre
of the other (the upper) disc is a perforation slightly smaller than the shank-head.
From the centre of this latter (upper) disc radiate to near the circumference four
or more (by preference six) cuts or slits in the disc. One only of these slits forins
a slot or channel sufficiently wide to allow the passage through or along it of the
neck of the shank flatwise. This last mentioned slot or channel terminates near
the circumference of the disc in a circular perforation of a size sufficient for the
easy passage through it of the shank-head. The other (under) disc has also in it
a slot or channel precisely similar to and corresponding with that in the upper
disc. The two discs are fixed one under the other, the two slots or channels
coinciding
The shank is formed of brass, iron or other suitable material. It has a flat
under-disc of suitable size to resist being drawn through the material to which the
button is to be fixed, and a flattened shank terminating in a small head or knob of
a size to correspond with the perforations above referred to

page_text: :
To fix the button, the shank is passed through the material and then through
the centre perforations in the two discs above described from the concave side of
such discs the elasticity caused by the slits in the upper of such discs allows the
shank hend to pass through, but, arrived through to the convex side of such disc,
prevents its being withdrawn. The under disc (having no slit other than the one
slot or channel) is rigid and supports the upper (slit) disc against any force that
may be used to withdraw the shank head through the latter
The shank head can only be withdrawn by turning it with the finger and
thumb so that it may be presented edgewise to the coincident slots or channels in
the 2 discs and then pushed from centre to circumference along such slots and
withdrawn through the perforations at the extremity of such slots near the
circumference of the coincident discs
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Amedee Combault and William Thomas Taylor in the Great Senl Patent
Office on the 3rd February 1883.
AMEDEE COMBAULT of 226 Regent Street in the County of Middlesex Manu-
facturers Agent and WILLIAM THOMAS TAYLOR of 20 Westbourne Terrace Harrow
Road in the County of Middlesex Esquire AN IMPROVED MECHANICAL BUTTON
The button consists of two separate parts: the knob or button proper (Drawing 1,
Nº 1), and the shank (N° 6). The former is composed of or contains two_equal
circular convexo-concave discs of thin steel or other suitable material. In the
centre of one of these discs (Drawing 1 N° 4) (to be placed under the other) is a
perforation sufficiently large to admit the easy passage of the shank-head herein-
after described. In the centre of the other (the upper) disc (Drawing 1 No 2) is a
perforation slightly smaller than the shank head. From the centre of this latter
(upper) disc (2) radiate to near the circumference four or more (by preference six)
cuts or slits in the disc. One only of these slits forms a slot or channel sufficiently
wide to allow the passage through or along it of the neck of the Shank flatwise.
This last mentioned slot or channel terminates near the circumference of the disc
in a circular perforation of a size sufficient for the easy passage through it of the
shank-head. The other (under) disc (4) has also in it a slot or channel precisely
similar to and corresponding with that in the upper disc. The two discs are fixed
one under the other, the two slots or channels coinciding.
The shank (Drawing 1 N° 6) is formed of brass, iron or other suitable material.
It has a flat under-disc of suitable size to resist being drawn through the material
to which the button is to be fixed, and a flattened shank terminating in a small
head or knob of a size to correspond with the perforations above referred to.
To fix the button, the shank is passed through the material and then through
the centre perforations in the two discs above described from the concave side of

page_text: such discs; the elasticity caused by the slits in the upper of such discs allows the
shank-head to pass through, but, arrived through to the convex side of such disc,
prevents its being withdrawn. The under disc (having no slit other than the one
slot or channel) is rigid and supports the upper (slit) disc against any force that
may be used to withdraw the shank-head through the latter
The shank-head can only be withdrawn by turning it with the finger and thumb
so that it may be presented edgewise to the coincident slots or channels on the two
discs and then pushed from centre to circumference along such slots and with-
drawn through the perforations at the extremity of such slots near the circumference
of the coincident discs
For buttons which it is not desired to make removable the slot or channel above
referred to may be dispensed with, as shewn in drawing N° 2
For greater security, a small spring (Drawing 1 N° 7) can be introduced under
the under disc (Drawing one N° 3) so as to prevent the shank being withdrawn or
escaping involuntarily. With the addition of this spring, the shank (Drawing 1
N° 6) may be made round instead of flat, as in such case the slot may be sufficiently
wide to allow of its general thickness passing through the slot. In witness whereof
we the said Amedee Combault and William Thomas Taylor have hereunto set
our hands and seals this third day of February in the year of our Lord One
thousand eight hundred and eighty three.
