ALFRED JULIUS BOULT of the firm of W. P. Thompson & Boult Agents for
Foreign Patent Solicitors of 323 High Holborn in the County of Middlesex and
6 Lord Street Liverpool in the County of Lancaster Engineer. 'IMPROVEMENTS
IN FOLDING POCKET SCISSORS [A. communication to him from abroad by the firm
of Böntgeu and Sabin of Solingen in the German Empire.]
"
This invention relates to an improved construction of pocket scissors which will
enable the same to be carried in the pocket more safely and conveniently than
those heretofore constructed.
The blades are substantially of the usual shape and jointed in the usual manner,
where however, the bows would commence in nu ordinary pair of scissors namely
just below the rivet or screw, there are only short extensions on the blades. To
each of these extensions is hinged, so as to freely rotate on the hinge-pin a shell or
case similar to the haft of an ordinary pocket knife, and consisting of a case of
sufficient size and suitable shape to enclose one blade of the scissors when folded
back upon the same. A stop limits the travel of each case. The blade extensions
have fingers or arms of suitable shape which, when the scissors are open press
upon springs in the backs of the cases, whilst when the scissors are closed they form
one end of the covering for the blades. A latch or lock is provided and serves to
keep the scissors closed when they are folded up.
The whole is so arranged that there will be no projecting parts when the scissors
are not in use.

ALFRED JULIUS BOULT of the firm of W. P. Thompson and Boult Agents for
Foreign Patent Solicitors, of 323 High Holborn, in the County of Middlesex and
6 Lord Street Liverpool, in the County of Lancaster Engineer *IMPROVEMENTS
IN FOLDING POCKET SCISSORS a communication to him from abroad by the firm
of Böntgen [sic] and Sabin of Solingen, in the German empire.
"
In the annexed drawing is represented a pair of pocket scissors having the arms
or "bows" box shaped and free to rotate round pins in the handle and of the
bladesff for the purpose of providing for the scissors, when closed or folded up,
a casing or shell which shall enable the same to be carried in the pocket like a pen
knife without injury to the pocket.
-
As represented in the annexed drawing the box shaped scissor "bows". are
capable of rotation round pins & and the cases or shells b b of the "bows" or
-arms B B¹ receive the extensions f-f-of-the blades provided with fingers a¹ a
Figure 2 shows this arrangement the upper covering plates b b of the bows B B¹
being removed. The extensions ff are so formed, that, as will be seen in Figure 5
at a', the fingers a' a³ slide past one another when the scissors are being folded up
-and-are-free-to-act-upon-the-springs cc.
The dotted lines in Figure 2 indicate the position c' of the spring which this
would assume by the action of the finger a. The latter, when this takes place
moves in front of the finger a².
Figure 5 shows the shape to be given to the elastic end of the spring c so as to
correspond with the notched part of the fingers a¹ a³
To enable the action of the "bows" of the scissors to be transmitted to their
respective blades, pins e are provided which, when the scissors are closed bear
against the cases or shells bb'. These pins are however so arranged that they
do not obstruct the turning back of the "bows" when the scissors are to be
folded up.
By transmitting the spring action to the fingers a' and as the front or cutting
portion of the scissors opens automatically.
When closed up the scissors would have the shape shown in Figure 4. A lateli d
turning on the pin p at the free end of one of the "bows," B, which can be
locked on the pin p' of, the other "bow" B' (the other half of the case) prevents
the scissors opening spontaneously.
It will clearly be seen by reference to the dotted lines of Figure 4, what the
position of the various parts will be how the box shaped "bows" close up and
how the cases or shells 6 6 with the springs c c constitute the covering of the
scissors.
They are completely enclosed, protected from injury and when carried in the
pocket can not tear it by any projecting parts.
Having now described this invention as communicated to me by my foreign
correspondents, I wish it to be understood that I am aware that latches similar to
that hereinabove referred to (d) have heretofore been used for pocket knives, I
therefore do not claim the same apart from its application in pocket scissors
constructed as above set forth, but what I claim is:
First: Folding pocket scissors so constructed that the "bows" B B', combined
with the flat springs c c and the latch d and capable of rotating on pins in the
extensions ff of the blades a a of the scissors, shall completely enclose the scissors
when folded up, substantially as described and shown.

page_text: Second. The box shaped bows B B' capable of rotating on the pins 8 of the
scissor blades a a, the casing or shells of which "bows" receive within them the
extensions ff of the blades, substantially as set forth.
Third: The arrangement of flat springs c c in such a manner that the notched
fingers a¹ a sliding past one another when the scissors are being closed, are capable
of acting upon the springs c c so as to cause the front or cutting portion of the
scissors to open automatically, substantially as set forth.
Fourth. The arrangement of the pins e bearing against the shells or cases b b so
as to transmit the leverage of the "bows" B B' to the flat springs c c and to cause
the "bows" B B¹ to move apart automatically substantially as described and
shown.
Fifth In scissors such as referred to, the arrangement of the latch or bolt d for
connecting the "bows" B B' which when the scissors are folded up, appear split
in the centre.
In witness whereof I the said Alfred Julius Boult have hereunto set my
band and seal this tenth day of May in the year of our Lord One
thousand eight hundred and eighty three.
