Improvements in Safety Pins or Holders.
We, EUGEN RODI and WILHELM WIENENBERGER both of Pforzheim,
Manufacturers, and OTTO KELLNER of 6 Neue Ross-strasse Berlin, Merchant, all
in the Empire of Germany, do hereby declare the nature of this invention to be as
follows:
The improvements forming the subject of the present invention consist in the
employment of one or more pins bent into a semi-circular or segmental form
pivoted in a suitably shaped case, and acted on by springs in such a manner that
when in the locked position they protrude from the case, and when unlocked they
spring back into the case, and, whether in the locked or unlocked position, the
point or points of the pin or pins is or are contained within the case so that
there are no projecting sharp points calculated to scratch or otherwise injure
the user, which frequently happens with safety pins of the ordinary construction.
The employment of a case containing the locking pin or pins has the further
advantage that a tasteful form can be given to the entire device, it can be
employed as a holder or carrier for ornaments of all kinds, and as a flower
holder when provided externally with a device suitable for holding flowers,
bouquets and so forth.
According to one arrangement the semicncular o segmental safety pin 18
pivotted in the interior of a case of rectangular form, and is actuated by means of
a link pivotted to a hinged flap or door of the case.
This flap is acted upon by a spring which, when a locking pin or latch is
released, presses the said flap outwards, withdrawing the safety pin back into
the case.
The locking of the safety pin in its closed position is effected by means of a
pin or latch which takes behind the radial arm carrying the curved part of the
safety pin.
This locking pin or catch may be withdrawn from behind the safety pin by any
suitable means, for example it may be mounted on a movable and spring urged
side of the case so that when such side is pushed inwards the locking pin or catch
is carried in clear of the safety pin and the latter is thereby released and springs
back into the open position.
To enable the curved safety pin to pass through the side of tho case so that
the point of the said pin is contained within the case when the pin is in its
closed or locked position two oponings aro provided in the said side one for the
passage though it of the body of the pin and the other for the reception of the
point.
According to a modification of the above described arrangement an oval or
other suitably shaped case contains two curved safety pins pivotted therein so as
to act in opposite directions, and these pins are moved into the closed or locked
position by pressing on two buttons or slides, and are released to enable them to
spring back into the case by pressing back a spring-actuated pin or catch by means
of a suitable button or slide.

page_text: In this case also the safety pins are pivotted inside the case.
Their radial arms
carry pins or projections against which act pressure slides that are guided in the
case by any suitable meaus, and are acted upon from outside by means of pressme
buttons or pushers. One of the pressure slides carries a 'spring, a tooth on which
passes in behind the other pressure slide immediately the pressure buttons or
pushers are pressed inwards so that the safety pins are locked in then closed
position by the said spring and catch tooth.
In order to withdraw the spring tooth a button or pusher is provided which
can be actuated from outside the case, and which pushes the catch spring away
from behind the pressure slide so as to allow the safety pins to spring back into
the case
By pressing the aforesaid buttons or pushers inwards the safety pins nie again
moved into the closed or locked position in opposition to the action of their
springs
According to another modification one, two, or more curved safety pins may be
moved by one, two, or more toothed racks whereby auy number of such cui ved
safety pins as may be requned to effect the desired object may be used in one
containing case. The said toothed racks, as also the entire mechanism, can be
fitted into a tube or into a narrow case so that this modification is specially suited
for brooches and the like.
In this arrangement the unlocking of the safety pins is effected by pressing
inwards buttons or pushers connected with the toothed lacks which latter gear with
toothed wheels or segments on the safety pins which are pivotted by means of pins
passing through the containing tube or caso. When the buttons or pushers are
pressed together the safety pins are turned by menus of these toothed wheels or
seginents, and are withdrawn into the case, whilst by relaxing the pressure on the
buttons or pushers a spring, situated between the latter, force thom outwards
whereby the safety pins are caused to turn on their pivots in the reverse direction
and to issue from the case. By thus pressing together the buttons or pushers the
object to be fastened or secured by the safety pins is released
According to yet another modification the movement of the safety pin is effected
in the reverse way, that is to say, when the button or pusher stands in its noimal
position the safety pin is inside its case, and when the button or pusher 18 pressed
inwards the toothed rack turns the safety pin by means of its loothed wheel or
segment so that it assumes its closed on locked position outside the case and a catch
spring comes into action to hold it in that position.
If the catch spring is pressed down the toothed 1ack is released, and a spuog
pushes it and the button of pusher back into their normal position. In this case
by pressing the button or pusher mwards the object to be secured is fastened.
It will be understood from the above description that the curved pins can be
moved by mechanism constructed in various ways without departing from the
nature of this invention, which consists essentially in a safety locking device or
holder composed of one or more semicircular or segmentally bent pins acted on by
springs, and pivotted inside a case in such manner that the points of such curved
pius are contained within the case whether the pius are m the opened or closed
position.

page_text: We, EUGEN RODI and WILHELM WIENENBERGER, Manufacturers of
Pforzheim and OTTO KELLNER, Merchant, of Berlin, in the German Empe, 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 safety pins, holders or fasteners to which curved or
hooked pins caied or formed on swivelling arms or levers are used, which pins in
their extreme positions enter the walls of the casing in such a manner that in the
opened as well as in the closed position the points are protected by the casing and
injuries by means of them are prevented. Our invention consists in improvements
in the construction on aiaugement of said safety pius or holders by means of which
the curved pins are moved compulsorily under sping action so that on releasing
the external parts operating the pins they either close ou open suddenly according
to the arrangement of the parts Preferably the pins are operated by means of
toothed racks engaging with pinions or toothed segments fixed to or formed on the
cu ved pins or the swivelling arms o levers carrying them, said racks being
prolonged to the outside of the casing of the safety pin or holder for operating
them in one direction and actuated by a sping on springs enclosed in the casing in
the opposite direction.
On the drawing appended hereunto safety pins or holders with our improvements
applied thereto are shown in several inodifications,
Figs. 1 and 1 showing a safety pin in which the spring effects the closing of the
same, while Figs 2 and 2 show a safety holder in which the opening 18 effected by
the spring.
Figs. 3, 4 and 5 shows a box shaped safety holder in which the racks are operated
by means of a central button.
Figs 6, 7, and 8 show an annulai safety brooch or support for the same.
In each of the several modifications the rectilinear movement of a rack effects
a rotary or swivelling motion of the curved pin by means of a pinion or toothed
segment formed on oi connected to the straight arm of the pin.
The safety pin or fastener shewn by Figs. 1 and 1 consists of a tubular case A
into which are inserted two cylindrical slides or bolts e and el formed with recesses
and rachs m and m' which gear with segments or pinions and n¹ formed on the
pivotted ends of the straight aims or parts of the pins c and c. A spring • placed
in compression between the ends of the bolts e and e' pushes them apart and holds
the curved pins in their closed position as shewn, the points of the pins entering
holes in the casing. By pressing the bolts e and e¹ inwards, the pins are withdrawn
into the case, and on release of the bolts returned to the position shewn on the
drawing.
То
In the modified arrangement shown by Figs. 2 and 2 the racks m and m¹ are so
placed into gear with the pinions n n' that they withdraw the curved pins into the
casing A when the bolts e and e' are pushed outwards by the spring o, while the
fastening of the holder to the diess is effected by pushing the bolts inwards.
hold the pins in their closed or fastening position, the knobs of the bolts are made
in two pails, one of which, hou h¹, is solid with the bolt, while the other, or '
is composed of a spring fixed to the other and opening outwards, and catches with
its projection behind the bent over end of the casing when pushed in. On the
catches boing released, the spring o pushes the bolts outwards and withdraws the
pins into the case.
The casing A may have ornamental facings or Jewelry attached to it.

page_text: In the modification shewn by Figs. 3, 4, and 5 a box shaped casing A is used,
which contains the mechanism for actuating the curved pins a c and a' c. The
racks m and m' gearing with the pinions n and n' have lateral extensions forming
opposite vertical racks p and p' which both engage with a spur wheel q mounted
on an axle that can turn in beatings in the casing A and be operated by a button
or rosetter. By turning the latter the fastener is opened or closed, while springs &
and attached in tension to the lacks and ends of the case hold the pins in their
fastening position
Figs. 6, 7, and 8 show an annular brooch or holder for the same, Figs. 6 showing
a front view, Figs. 8 a side view and Fig. 7 a perspective view of the same.
The
casing consists of two parts capable of sliding one in the other, which when
combined form a complete hoop which can be pushed together to unfasten the
holder. Springs s and s¹ in compression are inserted into the part A' in which the
pivots for the curved pins are mounted, the other part As being formed with
racks mm engaging with the pinions on the pins and opening the fastener when
pushed further into the part A¹.
In some cases the fastener or holder may be made with one curved pin only,
while in others more than two may be arranged in one casing or support, and two
or more pins may be operated by one rack.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claun is
1. In safety pins or holders with curved pins formed with or attached to levers
turning on pivots in the case of the holder, the arrangement of toothed pinions or
sectors formed on fixed on said levers and of sliding bolts formed with racks gearing
with the said pinions or sectors and operated from the outside in one direction and
by springs contained in the case in the opposite duection, substantially as herein-
before described and illustrated by the diawings.
2. In a safety pin or holder the combination of a case, one or more curved pins
formed with or fixed to levers tuining on pivots in the case, a pinion or toothed
sector formed or fixed on each lever, one or more sliding bolts each formed with a
rack engaging with one or more of said pinions or sectors and capable of being
actuated from the outside, aud one or more spings contamed in the case and
actuating the sliding bolt or bolts so as to tuin the pin or pins into one of its or
their extreme positions.
3. The manufacture and use of a safety pin or bolder with two curved pins con-
structed substantially as hereinbefore described with reference to Figures 1 and 1^
of the drawings.
4. The manufacture and use of safety pins or holders with curved pins con-
structed substantially as herein before described with reference to Figures 2 and 2^
of the diawings.
