Improvements in Pocket Knives.
I, JOHN THOMAS PARTINGTON, of Watford House, Victoria Road, Chester,
Railway Officer, 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 knives of that class the blades of which are adapted
to be shut within the handles of same, and opened out for use as occasion
requires it, and the present invention is designed to provide means whereby the
blades of such knives can be readily closed within the handles by a simple sliding
movement so as to reduce to a minimum, the risk of accidents occurring, and to
obviate the inconvenience of a person having to remove the glove from his or her
hand if worn thereon at the time, when engaged in opening a knife, the liability
of the finger or thumb-nails of the operator being broken, also being removed.
A further object of the invention is to render the blades of a knife constructed
in accordance with my invention, safer in operation, as owing to the said blades
not being allowed a lateral movement, it will be impossible for them to close upon
the user's fingers, as was the case in the clasp-knives heretofore, and at present
in use.
For the purpose of more clearly explaining this my invention so that same can
be readily carried into effect, I have referred to same upon the accompanying
sheet of illustrative drawings wherein :-
-
Fig. 1 is a plan view of a three-bladed knife shewn closed constructed in
accordance with the said invention.
Fig. 2 being a section of same upon line x, x, and
Fig. 3 a side view.
Fig. 4 is a similar view to Fig. 1 but in a reversed position and with two of the
blades opened out or extended, while
Figs. 5 and 6 are detail views of the closing and opening means and a modification
thereof, respectively.
Referring to the drawings, in which similar letters of reference indicate corre-
sponding parts throughout the various figures, therein is represented a knife, which
may be of any ordinary shape, the handle portion a being of hollow construction,
preferably rectangular in section (Fig. 2), and within such handle a are arranged
three (or any other suitable number) blades b, b², b².
The extremities a¹ a² of the knife-handle a, are open so as to allow of the said
blades being slid out to a sufficient degree through such openings, the said blades
being manipulated by means of studs c fixed to, or formed integral with the said
blades b, b, , and the heads of which studs c project through longitudinally
arranged slots e,
e of suitable length provided in the sides of the knife-handle a.
In lieu of these studs c, rings d may be provided for the same purpose,
convenient way of attaching these rings d to the knife-blades being shewn by
Fig. 6, wherein a ring is illustrated as being passed through a hole in a projec-
tion d' upon the knife-blade. These rings d can be turned, when not in actual use,
so as to lie flat against the sides of the knife-handle a.
a
Any suitable number of blades can be provided to a knife such as described, and
the ends a a² of the handle a may be provided with caps rivetted to such handle in
the usual manner, if desirable.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I..declare that what I
claim is :-
1. The improvements in pocket-knives, substantially as described, and as
illustrated.
2. In a pocket-knife having a slot or slots formed longitudinally in the hollow
handle thereof, a blade or blades adapted to slide within such handle and partially
through openings in the ends of same, substantially as and for the purpose specified,
and as illustrated by the accompanying drawing.
Dated this 7th day of December 1894.
