Improvements in Detachable Buttons or Studs.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings in the County of Middlesex, do hereby declare the nature of
this invention to be as follows:―
This invention relates to that class of detachable buttons or studs in which the
fastening is effected by means of folding wings or flaps, and the object of the said
invention is to afford means for automatically operating the wings after having passed
the button-hole.
For this reason the button is connected to a plate hereinafter called the base-plate,
which is provided with elastic arms serving to arrest the folding wings in both their
extreme positions. These wings are pivoted to the shank of the button which is
movable between the said elastic arms in the direction vertical to the said base-plate,
and as the free ends of the said arms are permitted to bear against the eccentrically
formed heads of the wings, the latter are forced by the said arms to occupy either of
their extreme positions, as soon as the said shank of the button is caused to transmit
motion upon turning the wings.
In order to effect the motion of the shank as aforesaid, precautions have to be taken
to operate the movable shank either automatically by the adjacent material of the
button-holes after having passed the latter or by pressing a knob projecting beyond
the button plate. In the first case a pair of levers acting upon the movable shank and
attached to the base-plate, in the latter case a prolongation of the shank passing
through the base-plate and the button, are preferably employed.

COMPLETE SPECIFICATION.
Improvements in Detachable Buttons or Studs.
I, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co. Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :—
My invention relates to that class of detachable buttons or studs in which the
fastening is effected by means of folding wings or flaps; and the object of my
improvement is to afford means for automatically operating the folding wings after
having passed the button hole. I attain this object by the mechanism illustrated in
the accompanying drawing in which
Figuras 1 and 2 represent the button with the folding wings in the position when
entering the button-hole.
Figure 3 is a side view, with unfolded wings.
Figure 4 is a view of Figure 2 from below.
Figure 5 shows a vertical section of my improved fastening device in enlarged
scale; and
Figure 6, a vertical section of a button provided with a fastening device of a some-
what modified construction, also in enlarged scale.
Similar letters refer to similar parts throughout the several views.

page_text: The button a is connected to a plate g, which is provided with the arms e, é, serving
to arrest the folding wings ff, pivoted at n n to the shank c in both their extreme
positions. The shank c is movable between and in the direction of said arms e e, the
ends of which bear throngh suitable holes i, i, of the wings ff, against the heads m of
the latter, which are formed on this side excentrically to the pivots n, n, so that the
arms, which have the tendency of a spring under certain conditions, are actuating the
wings. The latter are arrested in their extreme positions under the action of
the elastic arms e, e as soon as the square parts of the heads of the wings inect with
their faces, Figures 1 and 2. For this reason the holes of the shank c, in which the
wings rest, are slightly elongated in order to allow a certain play to the pivots n of
the wing. It will therefore be understood from the drawing that by causing the shank c
to depart from the button-plato g when the wings are in the position Figures 1. 2
and 5 the wings must unfold automatically. To effect this, either a pair of crank-
levers h, h, hearing against the button-plate g and the blunt end of the shank c, or a
rod k, Figure 6 passing through the plate and the button, is employed.
The operation of this locking device will be as follows. In the position shown in
Figures 1, 2, 4 and 5 the button is to be introduced into the button-holes until the
ends of the levers h, h, touch the adjacent solid material of the objects to be joined
together by the button, when the levers h, h, will rock on the plate g, whereby the
wings fare forced into the position shown in Figure 3, in which the device is locked,
and the long arm of the levers touches the button-plate g. When dotaching the
button from the objects held together as described, only one of the wings needs to
be turned in line with the shank c, whereupon the other wing. will follow corre-
spondingly, thereby the shank being pushed toward the button-plate and the
levers h, h, caused to occupy their original position, Figures 1 and 5. When
employing the rod k, Figure 6, to act upon the shank c, a slight pressure on the
knob is required to lock the fastening device automatically.
I am aware that prior to my invention detachable buttons and studs have been
made with vibrating wings pivoted to the shank of a button. I therefore do not claim
such composition, broadly.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is
First. The detachable button or stud herein described having the spring-arms e, e,
secured thereto, the movable shank disposed between said spring-arms, and the
wings ff, pivoted to said shank and acted upon by said spring-arms, substantially as
set forth.
Second. The detachable button or stud, herein described having the plate g, the
spring-arms secured thereto at their upper ends, movable shank disposed between said
spring-arins, the wings ff, pivoted at their inner ends to said shank and having holes or
openings through which the lower-ends of said spring-arms project, and the levers h, h,
secured to said plate g bearing at their inner ends upon said shank, substantially as
set forth.
