IN BUTTONS."
"IMPROVEMENTS
The button referred to has its lower plate or patten articulated to the lower or
free end of the central pin or shaft of the button in the following manner :-
The lower plate is hollowed in the centre, leaving on two of its sides shoulders,
whilst the other sides are supplied with ears or lugs pierced with holes for the
reception of the pin or axis on which the patten turns.
The shaft of the button at its lower or free end is cut at right angles, so as
to present two plain surfaces perpendicular to one another, and is here pierced
with a hole.
In the hollow space comprised between the two shoulders a flat and gently
arched spring or sheet of metal is placed, and on this the end of the button shaft
rests, being articulated to the patten by a pin passed through the lugs and the hole
in the bottom of the button shaft.
By this arrangement the lower plate or patten can be moved to the right or left,
the spring fixing it temporarily in either of these positions, so as to admit of its
passage through the button hole, and when the plate is brought into its normal
position, it is held perfectly rigid and secure by the spring's action.

The shaft of the button at its lower or free end is cut at right angles, so as to
-present-two-plain surfaces-perpendicular to one another, and is here pierced with a
hole.
In the hollow_space_comprised between the two shoulders a flat and gently
arched spring is placed, and on this the end of the button shaft rests, being
articulated-to-the-patten-by-a-pin-passed-through-the-lugs-and-the-hole-in-the-
bottom of the button shaft.
By this arrangement the lower plate or patten can be moved to the right.or left,
the spring fixing it, temporarily in either of these positions, so as to admit of its
passage through the button hole, and when the plate is brought into its normal
position it is held perfectly rigid and secure by the spring's action.
The novelty and characteristic feature of the Invention therefore is the patten or
lower plate of the button; instead of being loosely jointed to the button shaft, it is
held fixed in its two positions whether raised or lowered, aided in these movements
by the spring.
Fig. is an elevation of the button; Fig. 2 is a like view shown in section, the
patten being lowered, that is to say, occupying its normal position; Fig. 3 is a
similar section, the patten being raised to facilitate its passage through the button
hole; Fig. 4 is an elevation of a button, the view being taken at right angles to
that of Fig. 3; Fig. 5 is the underneath part of the button and a transverse
section of the same; Fig. 6 is a profile and plan of the spring. In all these Figures
the same letters indicate like parts.
a is the head of the button in metal, bone, ivory, and so forth, and more or less
ornamented as desired, and of any suitable form; b is the shaft or tail of the
button; this part is cut at right angles at its free end, so as to present two plain
surfaces perpendicular to each other; c is the patten or lower plate of the usual
form; it has two ears. or lugs d, d, and a hollow or notch e forming two
shoulders ff.
g is the pin or axis of articulation of the patten c; it passes through the ears or
lugs d, d, and the end of the tail b.
h is the blade spring placed in the notch e of the patten below the tail b. The
whole being disposed as described, it will be observed that the patten c may be
held securely in its normal or lowered position, as in Fig. 2, by means of the
spring h, which presses on the end of the shaft b or is rigidly held raised, as in
Fig. 3, by the same spring, which presses either on the right or left side of the
shaft b, the blade spring acting like a knife spring.
Finally what is claimed as the Invention is the movable and articulated bottom
plate acting by means of the spring, in the manner and for the purposes precisely
as herein described and as illustrated_by_the_accompanying Drawings..
In witness whereof, I, the said Hippolyte Payan, have hereunto set my hand
and seal, this Twenty ninth day of December, in the year of our Lord
One thousand eight hundred and seventy nine.
