Improvements in Detachable 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 detachable buttons or studs, in which the fastening is
effected by means of a pair of folding wings or flaps, separately pivoted to the shank
of the button or stud; and the objects of the same are to adapt these wings or flaps-
in such a manner, that firstly, the vibrating motion of either one will cause the
corresponding motion of the other, and that secondly, the wings will be securely
arrested and retained in both their extreme positions.
To effect this, the wings are either elastically formed in themselves or a pair of flat
springs are fastened thereto on their outer faces, and then connected together by a
link or bolt, or the connected wings are operated by a spring arranged within the
bollow shank of the button. In both cases the wings are so articulated, that the
connecting bolt or link of the same is adapted to be swung between the pivots when
operating one of the folding wings, so that this link or bolt will occupy a position,
within the shank, when the wings are in line with the latter, and it will be placed outside'
of the shank as soon as the wings are brought into the closed or locked position.
The wings may be operated either by turning one of them directly by hand or by
the aid of a pair of crank levers actuated by the material of the garment, shirt or
the like when the wings of the fastening device are introduced into the button-hole,.
or by a bolt extending through the button-plate to which the fastening device is
attached.

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 :-
The invention relates to detachable buttons or studs in which the fastening is
effected by means of a pair of folding wings or flaps separately pivoted to the shank
of the button or stud and the objects of the same are to adapt these wings or flaps
in such a manner that firstly the vibrating motion of either one will cause the corre-
sponding motion of the other, and that secondly, the wings will be securely arrested
and retained in both their extreme positions.
These objects are attained by the mechanism illustrated in the accompanying
drawing in which,
Figures 1 and 2 represent two different side elevations of a button provided with
the improved fastening device partly in section in the position, when entering the
button-hole.

page_text: Figure 3 is a side elevation of the button corresponding to Figure 1, but showing
the fastening device in an intermediate position.
Figure 4 is a side elevation of the button and
Figure 5 a view from below with unfolded wings.
Figure 6 shows a vertical section of the improved fastening device provided with
a modified device for unfolding the wings.
Figure 7 represents a side elevation partly in section of a modification with the
folding wings in the position when entering the button hole, and
Figure 8 is the same viów with the folding wings in an intermediate position.
Similar letters refer to similar parts throughout the several views.
The wings b, bare either elastically formed in themselves or a pair of flat
springs fare fastened thereto on their outer faces (Figure 4) and then connected
together by a hinge-joint d (Figures 1 to 6), or the wings are suitably connected by
a bolt d¹ and operated by a spring fo arranged within the hollow shank a of the
button (Figures and 8).
In both cases the pivots g, h of the wings b, b¹ are so arranged, that the connecting-
hinge-joint d or bolt d' is adapted to be swung between the said pivots when operating
one of the folding wings, so that the joint or bolt will occupy a position within the
shank a when the wings are in line with the latter (Figures 1, 2, 6 and 7), and it
will be placed outside of the shank as soon as the wings b, b' are brought into their
closed or locked position (Figures 4 and 5), so that the hinge-joint d or bolt d¹ must
pass in both cases between the two pivots g and h of the wings b, 6 whenever the
fatter are brought from either extreme position into the other (Figures 3 and 8).
In the device Figures 1 to 6 the wings b, b¹ are securely arrested in both their
extreme positions by the action of the springs f, f¹, which in the open position
(Figure 1) tend to draw the faces of the wings against another, while in the closed or
locked position the springs act from their joint d upon the wings like a pair of struts.
In the intermediate position of the wings, the springs f, f' are then bent so as to
touch the entire face of the wings b, b¹ (Figure 3).
In the modification shown in Figures 7 and 8 the eye of the wings through which
the bolt d¹ is passed, must be of an oblong form, to allow said bolt d to slide therein
when, in turning the wings, the latter is caused to pass between the pivots g and h.
The heads of the wings against which bears the block i under the action of a spring fo
are either formed in such a manner, that the wings permanently tend to occupy the
closed or locked position, or that the wings are secured in the open position as well as
in the locked or closed position.
When the wings are arrested in both their extreme positions they may be operated
either by turning them directly by hand, or by the aid of a pair of crank-levers k and !
(Figures 1-4) or by a bolt extending through the button plate (Figure 6) both
mechanism acting upon the hinge-joint d through the medium of a block i sliding
within the hollow shank a of the button. The crank levers are actuated by the material
of the garment, shirt or the like, when the wings of the fastening device are introduced
into the button-hole, while the bolt n is moved from outside of the face of the button-
plate towards the said hinge-jointed.
Having now particularly described and ascertained the nature of my said inven
tion and in what manner the same is to be performed as communicated to me
by my foreign Correspondent I declare that I make no claim to a detachable button
or stud in which the vibrating wings are pivoted to the shank or stay of the button
but what I claim is :-
First. The combination in a detachable button or stud of the vibrating, wings b, b¹
separately pivoted to the shank a, with a bolt. d', guided by an oblong eye in each
wing, substantially as and for the purpose specified.
Second. In a detachable button or stud the combination of the vibrating wings bb
separately pivoted to the shank of the button, with springs f, f' hinged together,
substantially as and for the purpose set forth.

Third. In a detachable button or stud the combination of the vibrating wings b, b¹
separately pivoted to the shank a, and connected together by means of a bolt d' with
spring and a guide block i, substantially as and for the purpose specified.
Fourth. The combination in a detachable button or stud of the vibrating wings b b1
separately pivoted to the shank a, the springs f, f¹, connected by a hinge or bolt d,
substantially as and for the purpose described.
Fifth. The combination in a detachable button or stud, of the vibrating wings b, b¹
separately pivoted to the shank a, the springs f, f¹ connected at one end to said wings
and hinged together at d, with the rod n passing through the button and hollow
shank a, substantially as and for the purpose set forth
