IMPROVEMENTS IN STUD FASTENINGS
Year: 1885

page_text: I OTTO RAFFLENBEUL Manufacturer of Hamburg in the German Empire do
hereby declare the nature of my said invention for "IMPROVEMENTS IN STUD
FASTENINGS" to be as follows:-
This invention relates to stud fastenings in which movable flaps are employed on
the underside of the pillar of the stud for attaching the stud to cuffs or other parts
of the dress. When the fastening is in its unused condition or open the flaps are
brought in a straight up and down position close and parallel to each other so
that they can be passed into, or be removed from the button hole. When the
fastening is in position the flaps are turned into position standing out opposite to
each on each side of the pillar of the stud.
The invention relates to improvements of stopping and arresting the flaps in
open or in closed position of the fastening so that the fastening can easily be
attached to cuffs or other parts of the dress, and also to prevent the fastening
from opening accidentally and becoming loose or lost.
The flaps may either be mounted on a square-arm of a pillar attached to the
head of the stud or solitaire on which arm they can turn by a spring action
produced by slotting that part of each flap that surrounds the square arm. This
part springs out and whilst it in consequence of this action, allows of being turned
on the square arm it will in open as well as in closed position be arrested and be
kept fast to the arm as in these positions the square opening of the flap fits
accurately and surrounds the square arm of the pillar....
In another modification each of the two flaps may be fulcrumed to the free end
of a separate pillar, the other end of which is fastened to the stud or solitaire.
The two pillars are formed of elastic sheet metal and are placed parallel and only a
small distance apart. The required resistance excercised by the flaps against an
alteration of position when either open or closed, is produced by a semi-square
shape of the flaps at the inner side of those ends fulcrumed to the pillars. This
semi-shaped form acts in a similar way as the square shape of the arm before
described and will force the free ends of the feathering pillars apart from each
other, whilst the flaps are turned. In open as well as in closed position the flat
sides of the semi-squares rest. against each other, and are kept in position by the
spring action of the pillars.
but this
The flaps may in some cases be formed with an upper rectangular arm,
is not part of the present invention.

I OTTO RAFFLENBEUL Manufacturer of 21 Graskeller Hamburg in the German
Empire 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 stud fastenings in which movable hinged flaps are
employed on the underside of the pillar of the stud for attaching the stud to cuffs
or other parts of the dress. When the fastening is in its unused condition or open,
the flaps are brought in a straight up and down position close and parallel to each
other, so that they can be passed into or be removed from the button hole. When
the fastening is in position the flaps are for purpose of locking turned into position
standing out opposite to each other on each side of the pillar of the stud.
The invention further relates to improvements for stopping and arresting these
flaps in open or in closed position of the fastening so that the fastening can easily
be attached to cuffs or other parts of the dress and also to prevent the fastening
from opening accidentally and becoming loose.
The flaps may either be mounted on a square arm of a pillar attached to the
head of the stud or solitaire on which arm they can turn by a spring action
produced by slitting that part of each flap that surrounds the square arm.
This
part springs out and whilst it in consequence of this action allows of being turned
on the square arm it will in open as well as in closed position be arrested and be
kept fast to the arm, as in these positions the square opening of the flap fits
accurately and surrounds the square arm of the pillar.
This construction is represented in Figs. 1, 2, and 4 of the drawings; m is the
square arm attached to the head A of the button by means of two pillars b b¹;
e e¹ are the two flaps placed on to the arm m by means of the square opening i;
the slit v secures a spring action of each flap on arm m. Fig. 1 is a side view of
the open fastening, and Fig. 2 a front view of same. Fig. 4 is a ground plan on
line of Fig. 2. Fig. 3 is a side view in section of the fastening when nearly
closed; the two flaps showing different and opposite ways when fully closed.
Figs. 5 and 6 are respectively side view and front view of an open fastening
somewhat modified. Instead of two pillars 6 6¹ at the ends of arm m only one
centrál pillar bu is used for attaching m to the button head A.
Figs. 7, 8, and 9 show another modification in which the two flaps e e¹ rest
against each other and not the one inside the other as in the first named figures.
The construction is otherwise the same as before described and will readily be
'understood with reference to the drawings.
Figs. 10 and 11 show the same construction applied to a collar stud but with a
central pillar instead of end pillars.
In another modification each of the two flaps may be fulcrumed to the free end
of a separate pillar, the other end of which is fastened to the stud or solitaire.
The two pillars are formed of elastic sheet metal and are placed parallel and only a
small distance apart.

page_text: The required resistance exercised by the flaps against an alteration of position
when either open or closed, is produced by a semi-square shape of the flaps at the
inner side of those ends attached to the pillars.
This semi-square shaped form acts in a similar way as the square shape of the
arm before described and will force the free ends of the feathering pillars apart
from each other, while the flaps are turned. In open as well as in closed position
the flat sides of the semi-squares rest against each other and are kept in position
by the spring action of the pillars.
This construction is represented by Figs. 12. 13 and 14. of the drawings of
which Fig. 12. is a side view and Fig. 13 front view of the open fastening.
Fig. 14. is a sectional view of the fastening closed halfway. When fully closed,
the two flaps would show different ways in direct opposite direction to each other.
d. d' are the spring pillars to which the flaps e. el are fulcrummed. The semi-
square ends of these flaps rest against each other and are acted upon by the spring
pillars.
The flaps may in some cases be formed with an upper rectangular arm, but this
is not part of the present invention.
Figs. 15 and 16 show the modification in which the flaps e. e¹ are furnished with
such rectangular arms o and o¹, which arms would prevent an accidental opening
of the fastening when in use as the button hole would keep the arms in position.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed I declare that what
I claim is:-
1. The spring fastening for studs or solitaires consisting of two flaps e el
surrounding a square arm m, attached to the button head by means of one or two
pillars, on which arın the flaps can be turned and be kept in open as well as closed
position by the spring action of the slitted portions of the flaps surrounding the
arm aforesaid and as represented in Figs. 1 to 11. of the drawings.
2. The modification according to which the turnable flaps are kept by two
spring like pillars d. d as represented by Figs. 12. 13 and 14 of the drawings.
