PROVISIONAL SPECIFICATION.
Improvements connected with Pocket or Clasp Knives.
We, STEPHEN WINCKWORTH SILVER Merchant, and WALTER FLETCHER,
Gun Maker, both of Sun Court, Cornhill, City of London, do hereby declare the
nature of this invention to be as follows:-
This invention has for object, certain improvements connected with pocket or
clasp knives.
The invention chiefly relates to those clasp knives which have a number of blades
and other articles, such as are known as sportsmens pocket knives, in which in
addition to a cutting blade or blades, a button hook, a piercer, a corkscrew, a claw
for removing stones from horses feet, a pipe plugger and the like, the stud pin on
which the several articles are pivotted being so arranged and removable that it
can be disconnected and other articles be readily substituted and be placed in
position in lieu thereof, such as would be required by an angler, or fisherman.
The springs are formed from a strip, like teeth of a grainer's comb, each being
within the shell that the tangs of the articles can be folded independently of each
other for opening and closing purposes under the desired strain of the springs for
retaining it or them in an open or a closed state. The strip having the spring
teeth is affixable in and removable from the shell by a turning action on a screw,
the head of which is preferably on the outside of the shell.
The pipe plugger as a disc may form one end of the shell, or the end may be
part of the shell for the disc to lodge within, or the end may be slotted for the
stem of the pipe plugger to pass into, the disc being exposed over the end.
The shell or handle may be made longer than the articles to form match box,
whistle, or case for small tools, or trace bolts with means of fixing for use.
The blade or articles may have a spring, or other fastening to keep them open
when in use.
The pivot pin, which as before stated is removable, may be flush with the shell
or have the ends to project, for the attachment of a spring shackle from which the
knife can be suspended from a string or cord from the pocket, or other part of the
users garment.

Improvements connected with Pocket or Clasp Knives.
We, STEPHEN WINCKWORTH SILVER, Merchant, and WALTER FLETCHER,
Gun Maker, both of Sun Court, Cornhill, City of London, 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 has for object certain improvements connected with pocket or
clasp knives.
The invention chiefly relates to those clasp knives which have a number of blades
and other articles such as are known as sportsmen's pocket knives, in which in
addition to a cutting blade or blades is a button hook, a piercer, a corkscrew, a claw
for removing stones from horses feet, a pipe plugger and the like, the stud pin

can be disconnected and other articles be readily substituted and be placed in
position in lieu thereof, such as would be required by an angler or fisherman.
The springs are formed from a strip, like teeth of a grainers comb, each being
within the shell that the tangs of the articles can be folded independently of each
other for opening and closing purposes under the desired strain of the springs for
retaining it or them in an open or a closed state. The strip having the spring
teeth is affixable in and adjustable as to tension from outside the shell by a turning
action on a screw the head of which is preferably on the outside of the shell.
The pipe plugger as a disc may form one end of the shell, or the end may be
part of the shell for the disc, to lodge within, or the end may be slotted for the
stem of the pipe plugger to pass into, the disc being exposed over the end.
The shell or handle may be made longer than the articles to form match box,
whistle or case for small tools or trace bolts with means of fixing for use.
The blade or articles may have a spring or other fastening to keep them open
when in use.
The pivot pin, which as before stated is removable, may be flush with the shell
or have the ends to project for the attachment of a spring shackle from which the
knife can be suspended from a string or cord from the pocket or other part of
the users garment said shackle being available when removed as a key to turn the
axle pin and also the spring adjusting screw when desired.
The annexed sketches sufficiently represent some of the articles which can be
fitted in the shell A. and be fastened thereto by the axle pin B and fixed by the
spring shackle C from outside the shell A, all the articles being put under tension
of the spring D and screw E. The articles shown are respectively a corkscrew F,
a piercer G, a knife blade H, button hook or stone remover 1, rimer J, can
opener K, saw L, oyster opener M, scissors N, penknife blade P, anglers hook
grippers or tweezers Q, pipe plugger R.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what
we claim is
1. The construction of a clasp knife with detachable axle pin and detachable
shackle for the ready removal and fitting of blades or other devices or articles as
and in the manner set forth and substantially as shown.
2. Providing a clasp knife with an affixable comb like spring and determining
the tension thereof by a screw from outside the shell or handle as set forth and
substantially as shown in the drawings.
