PROVISIONAL SPECIFICATION.
A New or Improved Mechanical Stud, Button, or the like.
We, ADOLF PICK and MAX FLEISCHNER, both of VII Schottenfeld gasse 67 Vienna
in the Empire of Austria, Manufacturers, do hereby declare the nature of this
invention to be as follows:-
The improvements forming the subject of this invention relate to that class of
mechanical button or the like in which the head is composed of two leaves or wings
attached to the free end or top of the shank with capability of being turned or folded
vertically together or horizontally in opposite directions and the present improve-
ments consist of a simple device whereby the folding of one of the leaves or wings
causes the other leaf to be likewise, simultaneously and automatically folded or
extended.
To this end the base of one of the leaves or wings slightly projects beyond the
other at the centre of motion or hinge joint so that as the longer one of the two
leaves is turned upon its centre one edge of its base engages with or catches beneath
the corresponding part of the other leaf and by exercising a lever action thereon
automatically turns it over also.
A mechanical button or the like provided with these improvements is represented in
the accompanying sheet of drawings, in which :-
Figures 1 and 2 show the device with the leaves or wings turned up or folded
together.
Figures 3, 4, and 5 illustrate three of the positions which the two leaves or wings
at their hases are adapted to assume when in operation.
As shown, the two leaves or wings a and b with their square faced hinged portions
or bases a¹ and b' are located within grooves c c formed in opposite faces of two
resilient or spring controlled parts e e which are held together by a rivet d and
constitute the shank of the button stud or the like..
The lower inner edge or angle 1 of one, a, cf the leaves or wings whilst the parts
are in their folded position extends a short distance below the corresponding edge of
the other leaf b as illustrated in Figure 1.
Now when the extended leaf a is turned in the direction of the arrow x, the edge
or angle 1 engages the corresponding angle of the hinged portion b' of the leaf b
(Figure 4) and by exercising a lever action it turns over the leaf b along with it
until they both occupy their extended or horizontal position as represented at
Figure 5.
The shank eel which at its upper end forms a kind of casing is contiguous to the
grooves or notches c c which receive the bases or hinged portions a' 6' of the leaves
furnished with inclines c c which facilitate the folding or extending of the
leaves a b.
The leaf a provided with the downwardly projecting base or hinged portion a¹
should at its upper end preferably be also extended upwardly beyond the leaf bas
shown in Figure 1 in order to afford a grip for the finger and thus still further
facilitate the manipulation of the device.

page_text: A New or Improved Mechanical Stud, Button, or the like.
We, ADOLF PICK and MAX FLEISCHNER both of VII Schottenfeld gasse 67 Vienna,
in the Empire of Austria Manufacturers 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 improvements forming the subject of this invention relate to that class of
mechanical button or the like in which the head is composed of two leaves or wings
attached to the free end or top of the shank with capability of being turned or folded
vertically together or horizontally in opposite directions and the present improve-
ments consist of a simple device whereby the folding of one of the leaves or wings
causes the other leaf to be likewise simultaneously and automatically folded or
extended.
To this end the base of one of the leaves or wings slightly projects beyond the
other at the centre of motion or hinge joint, so that as the longer one of the two
leaves is turned upon its centre one edge of its base engages with or catches beneath
the corresponding part of the other leaf and by exercising a lever action thereon
automatically turns it over also.
A mechanical button or the like provided with these improvements is represented
in the sheet of drawings accompanying our Provisional Specification in which
Figures 1 and 2 show the device with the leaves or wings turned up or folded
together.
Figures 3, 4, and 5 illustrate three of the positions which the two leaves or wings
at their bases are adapted to assume when in operation.
As shown the two leaves or wings a and b, with their square faced hinged portions
or bases a¹ and 61 are located within grooves cc formed in opposite faces of two
resilient or spring controlled parts e el which are held together by a rivet d and
constitute the shank of the button stud or the like.
The lower inner edge or angle 1 of the base of one a of the leaves or wings
whilst the parts are in their folded position extends a short distance below the
corresponding edge or base of the other leaf 6 as illustrated in Figures 1 and 3.
Now when the extended leaf a is turned in the direction of the arrow (Figure 1)
the edge or angle 1 engages the corresponding angle of the hinged portion b¹ of the
leaf b (Figure 4) and by exercising a lever action it turns over the leaf b along with
it until they both occupy their extended or horizontal position as represented at
Figure 5.
The shanke e which at its upper end forms a kind of casing is contiguous to the
grooves or notches c c which receive the bases or hinged portions a' b¹ of the
leaves furnished with inclines c c which facilitate the folding or extending of
the leaves a b.
The leaf a provided with the downwardly projecting base or hinged portion a¹
should at its upper end preferably be also extended upwardly beyond the leaf bas
shown in Figure 1 in order to afford a grip for the finger and thus still further
facilitate the manipulation of the device.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In a mechanical button or the like having leaves or wings such as a and b
attached to the free end of the shank with capability of folding forming the bases
or hinged parts of the leaves or wings ab angular or square and arranging them
in such manner that one of them a¹ projects somewhat beyond the other so that

page_text: when the leaf or wing a is turned upon its centre of motion or opened its projecting
edge l engages the underside of the hinged portion or base b' of the other leaf b, and
by exercising a lever action automatically turns it over also substantially as herein
shown and described and for the purpose stated.
2. In a mechanical button of the character referred to in Claim 1, the employment
of a shank consisting of two resilient parts e e' connected together and having
grooves or notches c furnished with inclines c', enabling the base portions a¹ b' of
the two leaves or wings a b which they embrace to be turned on their hinges or
centres of motion substantially as herein shown and described.
