IMPROVEMENTS IN STUDS AND SOLITAIRES
Year: 1885

Patent Agent and Engineer do hereby declare the nature of the said invention for
IMPROVEMENTS IN STUDS AND SOLITAIRES a communication from abroad by Eduard
Peine & Co. Manufacturers of Hamburg, in the German Empire to be as follows:-
This invention relates to improvements in studs, collar studs, solitaires and such
like fastenings and is particularly applicable for studs in which two separate wings
or flaps that fulcrum on separate axles or in separate bearings, are used as locking
pieces.
To the bottom plate of the stud or to the underside of same one or two pillars
are fastened and the flaps or wings are either placed or kept between arms of these
pillars or arms of the wings embrace the pillars to which they are kept by means
of pins or projecting taps or studs fitting into borings of the pillar. The flaps
when open are placed one beside the other at right angles to the bottom plate of
the stud and in this position they can be introduced into the button-hole after
which they are locked by turning the wings for a quarter of a circle. To keep
the wings in position in locked as well as in unlocked state, either the pillar or
the arms of the wings must be spring acting and either one or other part is
furnished with projecting edges whilst the other corresponding part is constructed
with grooves so as to set the wings when locked as well as when unlocked in a
similar way as is well known for the shank of folding cork-screws.

page_text: I WALTER ALFRED BARLOW of 6 St. Paul's Churchyard in the City of London,
Patent Agent and Engineer do hereby declare the nature of this invention a
communication from abroad by Eduard Peine & Co, Manufacturers of Hamburg in
the German Empire 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 improvements in studs, collar studs, solitaires and such
like fastenings and is particularly applicable for studs in which two separate wings
or flaps, that fulcrum on separate axles or in separate bearings, are used as locking
pieces.
To the bottom plate of the stud, or to the underside of same, one or two pillars
are fastened and the flaps or wings are either placed or kept between arms of these
pillars, or arms of the wings embrace the pillars to which they are kept by means
of pins or projecting taps or studs fitting into borings of the pillar.
The flaps when open are placed one beside the other at right angles to the bottom
plate of the stud and in this position they can be introduced into the button-hole
after which they are locked by turning the wings for a quarter of a circle. To
keep the wings in position in locked as well as in unlocked state, either the pillar
or the arms of the wings must be spring-acting and either one or other part is
furnished with projecting edges, whilst the other corresponding part is constructed
with grooves so as to set the wings when locked as well as when unlocked in a
similar way as is well known for the shank of folding cork screws.
This invention is illustrated by the accompanying sheet of drawings, wherein,
Fig. 1 represents in side elevation a stud showing the flaps in closed position, whilst
Fig. 2, shows this stud with open flaps, ready for insertion into a button hole;
Fig. 3, is a plan of Fig. 1; and Fig. 4 represents a modification.
a and b, are the flaps or wings, each of which fulcrums on a separate axle r
attached to pillars m, and n see Fig. 3. Each flap exerts a spring action against
the inner sides of the pillars and enters by means of the projections e e into corre-
sponding recesses or grooves of the pillars whilst the flaps are either in fully closed
or in fully open position. This is to set the flaps as before described. Each pillar
has two grooves, one in upright and one in horizontal position to fit the projections
of the flaps when open, as well as when being closed.
Instead of slitting the flaps as in Figs. 1, to 3, the flaps can be formed massive
and the pillars can be made feathering to set the flaps.
Instead of straight flaps or wings as in Fig. 1 to 3 each of these flaps can be
formed in shape of an angle as is shown in Fig. 4. By this arrangement the flaps
are forced to turn and close automatically when the fastening is forced into the
button hole.

page_text: Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed I declare that what
I claim is:-
A fastening for studs, solitaires and such like articles in which two flaps are
arranged between pillars m and n, on separate axles, to turn thereon, the flaps
carrying projections e to fit corresponding recesses of the inner sides of the pillars
by a spring action and baving for purpose to set the fastening in open or in closed
position substantially as described and shown by the drawinga.
