Improvements in or relating to Buttons or Studs.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake and 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, by which the base
plate is adapted to occupy such positions as to be enabled to easily pass the button-hole,
or to securely attach the button or stud to the garment or the like.
For this reason the said base plate of the button or stud is provided on its under
face with a bow or bows to engage with and riding upon a bolt or pin at the end of
the shank of the button in such a manner, as to allow a lateral movement in two
opposite directions, as well as a folding or oscillating motion, of the base plate in both
its extreme lateral positions. This is to enable the foot-plate in either of its lateral
end positions to be turned upright, so as to occupy a position in line with the shank
so that it can easily pass through the button-hole.
In order to retain the base-plate in either of its positions required for attaching or
detaching the button to the garment or the like the shank of the button or stud is
surrounded by an axial movable socket bearing by the aid of a spring against the base
plate of the button.
The aforesaid bow or bows of the base plate forming a passage for the pin or bolt at
the end of the shank, are provided with an interstice or notch into which engages the
said pin or bolt of the shank under the action of the said socket and spring to arrest
and retain the foot-plate in its closed position, which is rectangular to the direction of
the shank of the button. In the upright or open position of the foot-plate the said
socket and spring bear against the blunt ends of the same.

Improvements in or relating to 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 :-
This invention relates to that class of detachable buttons or studs, in which the base
plate is adapted to occupy such positions as to be enabled to easily pass the button-hole
or to securely attach the button or stud to the garment or the like; and the object of
the said invention is to afford means for allowing a lateral movement of the base plate
in two opposite directions, as well as a folding or oscillating motion in both its extreme
lateral positions and to arrest the said base-plate in both its extreme positions for the
introduction into the button hole as well as in an intermediate position in which the
button is locked or secured to the garment.
This object is attained by the mechanism illustrated in the accompanying drawing in
which
Figures 1 and 2 represent two vertical side elevations partly in section of the button
with its base plate in the position when entering the button hole;

page_text: Figure 3 shows the button partly in section with said base-plate after it has passed
the button-hole in that position in which it is prepared to be laterally shifted into the
locked position. Figure 4 is a sectional side elevation of a button after it has been
shifted into its locked position, and
Figure 5 is another side view of the fastening device as shown in Figure 4.
Similar letters refer to similar parts throughout the several views.
The base plate d of the button or stud is provided on its inner face with a bow or
hows h to engage with and riding upon a bolt or pin g at the end of the shank a of
the button in such a manner as to allow a lateral movement of the said base-plate d in
two opposite directions as well as a folding or oscillating motion of the same in both
its extreme positions. By these means the foot plate d is enabled in either of its
lateral end positions to be turned upright, so as to occupy the position shown in
Figures 1 and 2 in line with the shank a so that it can easily pass through the
button hole.
In order to retain the foot or base plate d in either of its positions required for
attaching or detaching the button to the garment or the like, the shank a of the button
or stud is surrounded by an axially movable socket & bearing by the aid of a spring f
against the said base plate of the button. The bow or bows of the base plate d
forming a passage for the pin or bolt g at the end of the shank a, are provided with
an interstice or notch k into which engages the said pin or bolt g under the action of
the socket and spring f resting upon the rear face of the button plate c, to arrest
and retain the foot plato d in its closed position (Figures 4 and 5) which is rectangular
to the direction of the shank a of the button. In the upright or open position
(Figures 1 and 2) of the base or foot plate, the said socket & bears against the blunt
ends of the same.
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 :-
In a detachable button or stud, the combination of the foot or base plate d having a
bow or bows provided with a notch k, with the pin g at the end of the shank a, the
socket and the spring f, substantially as, and for the purpose set forth.
