AN IMPROVED BUTTON FOR ARTICLES OF DRESS.
Year: 1878

page_text: LETTERS PATENT to Alexandre Eleonore Roulin, of Rue Corbeau, No. 16, at
Paris, Manufacturer, for the Invention of "AN IMPROVED BUTTON FOR
ARTICLES OF DRESS.
Sealed the 28th January 1879, and dated the 6th August 1878.
PROVISIONAL SPECIFICATION left by the said Alexandre Eleonore Roulin
at the Office of the Commissioners of Patents on the 6th August 1878.
ALEXANDRE ELEONORE ROULIN, of Rue Corbeau, No. 16, at Paris, Manufacturer.
"AN IMPROVED BUTTON FOR ARTICLES OF DRESS."
This Invention relates to an improved construction of that description of button
or stud in which the head is removable from the shank and back plate, being held
thereon by a catch.
According to the present improvement the head contains a spiral spring, the outer
end of which is formed with a hook hooking on to an internal projection on the
rim of the head, while the other end acts as a catch or bolt, catching into a groove
or recess formed in the end of the shank. At a point some distance from its outer
fixed end the spring has a stud projecting through a hole in the rim of the head, so
that on pressing the stud with the finger the catch or bolt at the inner end of the
spring is forced out of the groove or recess of the shank, so that it can be withdrawn
therefrom.
The sbank has a central hole, in which fits a pin on the under face of the head,
so as to hold the latter securely thereon.
.
Instead of only one spiral spring two such springs may be employed, having their
one end fixed at diametrically opposite points, either to the rim of the head or in a
notch near the free end of the other spring, the free ends of the springs being made
to catch in opposite notches or on opposite sides of a circular groove on the
shank.
Each spring has a stud which projects at diametrically opposite points through
the rim of the head.

"AN IMPROVED BUTTON FOR ARTICLES OF DRESS."
This Invention relates to an improved construction of that description of button
or stud in which the head is removable from the shank and back plate, being held
thereon by a catch.
According to the present improvement the head contains a spiral spring, the
outer end of which is formed with a hook hooking on to an internal projection on
the rim of the head, while the other end acts as a catch or bolt, catching into a
groove or recess formed in the end of the shank. At a point some distance from its
outer fixed end the spring has a stud projecting through a hole in the rim of the
head, so that on pressing this stud with the finger the catch or bolt at the inner
end of the spring is forced out of the groove or recess of the shank, so that it can
be withdrawn therefrom.
The shank has a central hole, into which fits a pin on the under face of the head,
so as to hold the latter securely thereon.
Instead of only one spiral spring two such springs may be employed, having
their one end fixed at diametrically opposite points, either to the rim of the head or
in a notch near the free end of the other spring, the free ends of the springs being
made to catch in opposite notches or on opposite sides of a circular groove on the
shank.
Each spring has a stud, which projects at diametrically opposite points through
Fig. 1 shews a vertical section of the improved button or stud.
Fig. 2 shews the same section, the head being separated from the shank.
Fig. 3 shews a plan of the interior of the head.
The casing A of the head, which is of stamped metal, has at the point a of its
periphery an aperture or slot, while at b the periphery is cut and bent inwards so
as to form an abutment or fulcrum for the hooked end c of the spiral spring catch B.
This is provided at d with a projection or stud projecting through the slot of the
casing, while its inner end e is made to curve towards the central guide pin h, and
acts as a catch in springing into the circular groove e¹ of the shank f, when this is
inserted into the head, and is thus made to hold the head securely on the shank
until by an inward pressure exerted by the hand on the stud d the spring B is
pressed inwards so as to withdraw the part e from the groove when the head can
be removed. The guide pin h fits into the hollow o of the shank, which has the
lower head or plate p formed or fixed upon it.
Instead of forming the shank with a groove as shewn, it might have a hole or
recess, into which a pin or stud formed or fixed on the spring B would enter.
Fig. 4 shews a sectional plan of a modified arrangement in which two compound
spring catches are used, the one forming the abutment of the other, as will be
readily understood from the Drawing.
The same letters of reference indicate the same parts as in the preceding
Figures.
Having thus described the nature of my said Invention, and in what manner the
same is to be performed, I claim the construction of buttons or studs wherein the
removeable head is secured to the shank by means of one or more spiral spring
catches, the outer end of which is fixed, while the inner free end catches into a

page_text: groove or hole on the shank, and is released therefrom by pressure on a stud pro-
jecting from the spring catch through the side of the head, substantially as herein
described.
In witness whereof, I, the said Alexandre Eleonore Roulin, have hereunto
set my hand and seal, this Thirty-first day of January, in the year of our
Lord One thousand eight hundred and seventy-eight.
