Improvements in Clasp-pocket-scissors.
I, EDMUND JANSEN of Solingen, Kingdom of Prussia, German Empire, manufac-
turer of pocket-knives, do hereby declare the nature of this invention to be as
follows:-
My invention of improvements in clasp-pocket-scissors refers to a new spring
mechanism for automatically opening a pair of scissors belonging to such class in
which the handle parts on the scissors blades form the scissors handles when clasped
together and a cover for the scissors when clasped together.
The principal feature of my invention consists in the application of a double armed
spring lever being connected to pressure springs, by which arrangement the automatic
opening of the scissors is assured.
The pocket scissors consist of two handle parts at the ends of which the scissors
blades are fixed by means of pins around which the blades can turn. Besides
these pins the scissors blades are provided with notches and the handle parts with
other pins against which the notches lay on. The double-armed spring levers are
arranged inside the shells of the handle parts by means of pins and can turn
round the same. In pressing on the handle parts the pressure springs will be
stretched and as soon as this pressure ceases these springs will press the handle
parts asunder.
In
When the scissors are clapsed together the blades press against the opposite
parts of the spring lever and by such means cause that the pressure springs are
also stretched in this position, whereby the handle parts are pressed asunder.
order to keep the handle paris together I employ any bar or hook in connection
with a pin.
.
When closed the backs of the scissors are entirely closed on the outside by
means of the spring levers, which turn round a pin.

page_text: I, EDMUND JANSEN of Solingen, Kingdom of Prussia, German Empire, manufac-
turer of pocket knives, 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 :-
My invention of improvements in clasp-pocket-scissors refers to a new spring
mechanism for automatically opening a pair of scissors, belonging to such class in
which the handle parts on the blades form the scissors handles when open, and a
cover for the scissors when clasped or shut up.
The principal feature of my invention consists in the application of a double armed
spring lever, in connection with pressure springs.
In order to make my invention more clear, I refer to the accompanying drawing,
in which similar letters denote similar parts throughout the different figures and in
which Fig. 1 shows a view of my improved scissors when open.
Fig. 2 shows a view of the same shut up so as to be carried in the pocket.
Fig. 3 shows a side view of the double lever and pressure springs.
Fig. 4 is an end view of fig. 3.
The construction of the scissors is as follows:
To the short legs care hinged the handles (the top sides of which are
removed in order that the springs may be seen) by the pins bb, and at the
same time the handles are fitted with stop pins d d so that the handles cannot
turn too far round.
In the middle of the handles are the double lever springs - hinged
on the pins ss, the outer end of these springs rest against each other, when the
scissors are open (fig. 1).
To these double lever springs are other springs fitted, the free ends of
which rest against the short arms of the scissors proper.
The bottoms of the handles are provided with pins kg, the pin g is fitted with
a catch i, which when the scissors are closed hooks on the pink (fig. 2), and
prevents them accidently opening in the pocket.
On pressing the handles the springs ff are put in tension and on the
pressure on the handles being released the springs f¹ force the handles apart,
and so open the blades a a¹ of the scissors.
When the scissors are shut up (fig. 2) the springs
tend to force the handles
open but are prevented from doing so by the catch, but on this catch being
released from the pink the scissors fly open of their own accord.

page_text: Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, declare that what I
claim is :
1). In clasp-pocket-scissors a pair of scissors a a¹ having handles h³ hinged to
said scissors a a¹ in combination with the double lever springs ff and springs fƒ³
and catch i, substantially and for the purpose as described.
