PIERRE ZÉPHIR STÉPHANE BULOT, Jeweller and Chain Manufacturer, of the City
of Paris, in the Republic of France. IMPROVEMENTS IN STUDS AND BUTTONS FOR
SHIRTS, CUFFS, AND WEARING APPAREL."
The features of novelty consist entirely in the combination of a double button
with movable plate and special locking device, the object being security when
fastened, whether used as buttons or studs for shirts, cuffs, or clothing generally.
The special characteristics of the Invention are the disposition of the mechanisın
rendering the plate movable at will, and the adjustment of the button in the position
it is desired to occupy, so that when once so fixed it cannot accidentally dislodge
when passed through the button hole.
The button or stud consists of two essential parts if in metal, and if partly
metallic in three parts, that is, when the head is of bone, ivory, mother of pearl,
and so forth.
For wholly metallic buttons the two parts comprise, 1st, the button properly so
called, having in the centre its shaft for receiving the movable plate; 2nd, the
movable plate, which in conjunction with the first part forms the complete button.
This plate when attached to the shaft turns like a moving bridge.
For buttons whose head is non-metallic the ensemble consists, 1st, of the head,
which is of any substance other than metal; 2nd, the shaft of metal similarly con-
structed to that of the button, wholly metallic; 3rd, and finally, the movable
plate.

page_text: Below the head is the shaft, attached to it in form of a small metal blade or
plate fixed below the head in a diametrical section. This shaft comprises in its
combination a circular opening with rim forming what may be termed the male
portion of an eye, and another placed above forming at its base the opening
necessary to form a lock with the part of the blade in relief, which by its action
forms a spring stop or catch. The shaft is bent at right angles in the centre, so that
the lower part in a horizontal plane may serve as support for the reception of the
movable plate.
The disposition therefore of the openings in the shaft and its obligatory form at
right angles constitute the 1st part of the Invention, which is completed by the
application of the movable plate.
For buttons whose heads are non-metallic the end of the shaft is a little longer,
and bears a screw or rivet. The movable plate is a small plate bearing the relief
and all the apertures necessary, so that it may be immediately placed on the shaft.
This important part of the button bears a circular opening, which forms the female
portion of the eye on three sides so as to form a spring.
A. small tenon in relief forms a lock or catch, so as to solidly keep the button
firmly locked when once in the position it is to occupy, and open when necessary
to avoid any deviation of the plate when the button is to be fixed.
The plate is fixed on the platform of the shaft in placing its circular opening on
the male portion of the eye of the plate; a slight pressure on a similar piece used
for putting the eyes in position suffices to open the rims and form a small rivet,
which whilst imprisoning the plate leaves it all the mobility desired for the exercise
of its functions.
A circular rim in relief runs along the plate, so that this part, always in contact
with the wrist, is never interfered with.

PIERRE ZÉPHIR STÉPHANE BULOT, Jeweller and Chain Manufacturer, of the City
of Paris, in the Republic of France. "IMPROVEMENTS IN STUDS AND BUTTONS FOR
SHIRTS, CUFFS, AND WEARING APPAREL."
The features of novelty in this Invention consist in the combination of a double
button with movable plate and special locking device, the object being security
when fastened, whether used as buttons or studs for shirts, cuffs, or clothing
generally.
The special characteristic of the Invention is the disposition of the mechanism,
rendering the plate movable at will, whilst facilitating the adjustment of the button
in the position it is desired to occupy, and when once so fixed it cannot be acci-
dentally dislodged when passed through the button hole.
In order to clearly demonstrate the principle the button is shown by the accom-
panying Drawings in all its phases, in detail and in a complete state, seen before
being placed in the button hole, and as it would appear when fixed therein.
The button consists of two essential parts if in metal, and if partly metallic in
three parts, that is, when the head is of bone, ivory, mother of pearl, and so forth.
For wholly metallic buttons the two parts comprise, 1st, the button properly so
called, having in the centre its shaft for receiving the movable plate; 2nd, the
movable plate, which in conjunction with the first part forms the complete button.
This plate when attached to the shaft turns like a moving bridge.
For buttons whose head (forming the principal part of the button) is non-metallic
the ensemble consists, 1st, of the head, which is of any substance other than metal;
2nd, the shaft of metal similarly constructed to that of the buttons, wholly metallic;
3rd, and finally, the movable plate.
There is nothing new in the head of the button A, which may be ornamented and
jewelled. Below the head is the shaft B, attached to it as shown, Fig. 1, and is in
form of a small metal blade or plate. This shaft comprises in its combination a
circular opening C with rim D, forming what may be termed a sort of eye, see
Fig. 2, and another E above it, as shown by the plan, forming at its base the
opening necessary to form a lock with the part of the blade in relief, which by its
action forms a spring stop or catch. Another opening E¹ is at the end of the shaft
and forms a notch.
The shaft is bent at right angles in the centre, see Fig. 3, so that the lower
part F in a horizontal plane may serve as support for the reception of the movable
plate.
The disposition therefore of the openings in the shaft and its obligatory form at
right angles constitutes the 1st part of the Invention, which is completed by the
application of the movable plate.
For buttons whose heads are non-metallic the end of the shaft G is a little longer,
and bears a screw or rivet.
The movable plate P, Fig. 4, is a small metal plate, which receives and is of the
requisite form, and bears the necessary openings to admit of its instant placement
on the shaft. This important part of the button bears a circular opening H, and in
addition a small blade I, free on three sides, to form a spring. A small tenon J
forms a lock or catch to keep the button firmnly locked when once placed in the
position it is to occupy, as well as open when so required to avoid any deviation
of the plate when the button is to be fastened.[
The plate is fixed on the platform F of the shaft by placing its circular opening H
on the projecting portion of the eye of the plate, and a slight pressure on a similar
piece (used for putting the eye in position) suffices to open the rims and forms a

page_text: species of rivet, which whilst imprisoning the plate leaves it all the mobility desired
for the exercise of its functions.
A circular rim K in relief runs along the plate, so that this part, always in contact
with the wrist, is never interfered with.
Fig. 5 represents the button open; Fig. 6 shows the button closed.
I claim as my Invention the button shaft B, with circular opening C, and rim D,
and eyes E, E¹. I claim also the movable plate P, with circular opening H, tenon J,
platform F, and rim K, as and for the purpose herein set forth.
In witness whereof, I, the said Pierre Zéphir Stéphane Bulot, have hereunto
set my hand and seal, this Seventh day of April, in the year of our Lord One
thousand eight hundred and seventy-nine.
