1 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 detachable buttons or studs in which the fastening is
effected by means of folding-wings or flaps pivotted to the stay of the button.
The main objects of the said invention are, first, to afford facilities for the proper
movement of the folding-wings; and second, to avoid the injury of the button holes
when employing angular shaped folding-wings or flaps.
In carrying the said invention into practice the button is fixed to a plate which
carries the post or stay in which the folding-wings or flaps are pivoted. These flaps
which form crank-levers are connected by means of links in the direction of the post
or stay with a plate or disc which is movable in the direction of the length of the
said post or stay which also serves as a guide for the said movable plate or disc.
The links connecting the movable plate or disc with the folding-wings or flaps
are preferably formed so as to act as a spring, in order to secure the flaps in both
their open and closed positions, or the saine object may be attained by other well-
known means in direct combination with the flaps.
When angular shaped flaps are employed the aforesaid plate or disc is not connected
with the flaps, and serves only to cover the ends of those arms of the flaps which
fold into the post or stay of the button-plate, in order to protect the button holes
from being injured by the said ends of the projecting arms of the wings or flaps.

page_text: For this purpose the said plate or disc is made in the form of a ring for receiving
the post or stay of the button.
The button is to be introduced into the button-hole, when the folding-wings are
turned so as to stand in the direction of the post or stay of the button and will
remain in this position until the said disc or ring touches the adjacent solid material
of the parts to be joined together by the button. The said disc or ring will then be
pushed towards the button plate thereby forcing the flaps to unfold and the button is
attached to the parts to be joined together.

page_text: 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 the said 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 detachable buttons or studs in which the fastening is
effected by means of folding-wings or flaps pivoted to the stay or shank of the
button.
The main objects of the said invention are, first, to afford facilities for the proper
movement of the folding-wings; and second, to avoid the injury of the button holes
when employing angular shaped folding-wings.
These objects are attained by the devices illustrated in the accompanying drawings,
in which
Figures 1 to 4 show a button with angular shaped folding-wings provided with
means for covering the short arms of the wings.
Figures 5 and 6 represent the improved button in the position for introducing it
into the button holes.
Figures 7 and 8 are two different elevations of the improved button when being
locked.
Figure 9 is a bottom view of figure 7.
Figure 10 is the same with two separate pivots one for each folding-wing.
Figure 11 is a bottom view of figure 6; and
Figures 5 and 7 are diagrams of the fastening device as represented by
figures 5 and 7.
Figures 12 to 16 represent a modification of the fastening device shown in
figures 5 to 11, and
Figures 17 and 18 are vertical sections of the button drawn to an enlarged scale
provided with this fastening device.
Similar letters refer to similar parts throughout the several views.
In the device shown in figures 1 to 4 the button a carries the stay or shank c to
which are pivoted the well-known angular shaped wings f, g. The arms g of these
flaps folding into said post or stay are loosely connected with a plate or ring d, which
serves to cover the ends of those arms in order to protect the button holes from being
injured by the projecting ends of the said arms. For this purpose, the disc dis
made in the form of a ring for receiving the post or shank c, whereupon it loosely
slides.
In the fastening device shown in figures 8 to 11 the ring or disc d is connected at
the point by means of the arms e with the folding-wings forming one armed or
crank-levers f, g. The said wings rest by their pivots n in the shank c which is
carried by a plate fixed to the button a. The disc d which is movable in the

page_text: direction of the shank serving as a guide for the motion of the plate d. It is
preferable to form the arms e so as to have the tendency of a spring in order to
arrest the turning flaps in both their final positions (figures 5 and 7).
In the modification shown in figure 10 both flaps, are pivoted separately to the
shank c.
In the modification shown in figures 12 to 18 the arms e, e forming a
U-shaped spring the ends of which bear through suitable holes f¹, f¹ against the
heads o, o of the folding-wings f₁f which are formed on this side eccentrically to
the pivots nn, so that the arms e under certain conditions are actuating the wings ff.
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 o of the wings meet with their faces
(figures 17 and 18). For this reason the holes of the shank e in which the wings
rest by their pivots n are slightly elongated in order to allow a certain play of
the pivots.

It will therefor be understood from the drawing that by causing the plate d to
approach the button plate & when the wings are in the position figures 12, 13 and 17,
the wings must unfold automatically just as in the devices heretofore described.
The operation of these locking devices will be as follows: In the positions shown
in figures 1, 2, and 4, in figures 5, 5, 6 and 11, and in figures 12, 13 and 17 the
button is apt to be introduced into the button-holes until the plate or disc d touches
the adjacent solid material of the objects to be joined together by the button, when
the plate d will be pushed toward the plate b, whereby the wings are forced into the
positions represented in the figures 3, or 7, 7, 8, 9, 10, and 11, or 14, 15, 16 and 18,
in which the devices are locked. When detaching the button from the objects held
together as described either one of the wings f may be turned in line with the stay or
shank c whereupon the other wing as well as the plate d will follow correspondingly
and the latter will be serviceable in withdrawing the button out of the button hole.
The applicant is aware that prior to this invention detachable buttons and studs
have been made with vibrating wings pivoted to the shank or stay of the button.
He does not therefore claim such combination 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 combination in a detachable button or stud of angular shaped wings f g
pivoted to the shanke with the ring or disc d movable in the direction of said shank
substantially as, and for the purpose, described with reference to figures 1, 2, 3 and 4.
Second. The combination in a detachable button or stud, of wings / pivoted to a
shank with a disc or plate d having arms e connected with the said wings,
substantially as, and for the purpose, specified, with reference to figures 5, 5ª, 6, 7,
7, 8, 9, 10, and 11.
Third. The combination in a detachable button or stud, of wings f pivoted to a
shanke with elastical arms ee moving in the direction of said shank, substantially
as, and for the purpose, set forth, with reference to figures 12, 13, 14, 15, 16, 17
and 18.
