Improvements in Pocket Knives and the like.
I EDMUND PAUL JERRARD of 26 East Street Manchester Square W. (late of
16 Matham Grove East Dulwich S.E.) Mechanic 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 :-
or
and
This invention relates to pocket knives, pen knives, instrument knives, and the
like and consists in the combination with one or more blades, one or more blades and
corkscrew other instruments, of a wire cutter or nipper so constructed as to form
a compact instrument or knife of suitable size for carrying in the pocket, and it has
for its objects, firstly; utility, as it affords a pocketable, ready and convenient
means for cutting small wires such as are used in picture hanging, wiring champagne
bottles etc., small nails, pins etc. etc. Secondly, economy; as it combines a wire
cutting instrument with a pocket knife at little or no extra expense. Thirdly,
convenience, as it provides an additional useful instrument with little or no extra
bulk.
In declaring the objects of my invention to be utility, economy and convenience,
I wish to be clearly understood to mean and imply that the objects of my invention,
are improvements in pocket knives, which improvements are brought about or
caused by the greater usefulness, economy, and convenience derived from the
combination of a handy wire cutter or nipper with a pocket or instrument knife.
In carrying my invention into practical effect, I add my wire nipper or cutter to
any ordinary form of spring pocket or instrument knife; which said knife I
construct with tools, materials and parts according to the manner and means known
to and generally adopted by cutlers at the present time, and I effect my improve-
ment by lengthening the pivot end of a blade, file, button hook, screw driver, or
other instrument included in and forming part of a spring pocket knife; and the
said elongated end I make of a suitable shape to form one half of a shear or cutter,
and the other half of the cutter I form by lengthening one end of the scales or
sides of the handle of the knife beyond the pivot hole, and I shape the said
lengthened end of scale or handle (which I preferably make of hardened steel,) to

page_text: correspond and act in conjunction with the half cutter formed on the end of the
blade, file, button hook, screw driver, or other instrument, so that when the knife
is rivetted together in the usual manner, the two half cutters act or may be made
to act in conjunction with one another, and together form a powerful wire nipper
or cutter in combination with a spring pocket knife of ordinary dimensions, the
whole forming a useful and very compact knife for the use of gardeners, bell
hangers, electricians, shopmen, packers and others. The steel or metal scales or
handle of the knife may have outer scales or coverings of horn, bone, ivory, pearl,
tortoiseshell, silver, gold, or other material in which case the said outer scales are
shaped in such manner as to afford access to the inner scale forming one half of the
shear or cutter.
I sometimes form my cutter independently of the scale or handle of the knife, in
which case I take two blades, or one blade and another instrument, or two
instruments, such as are usually included in spring pocket or instrument knives,
and the ends projecting beyond the pivot or rivet which joins these two blades, or
blade and another instrument, or other instruments, I make of suitable shape or
shapes so that when pinned or rivetted together and operated by the fingers and
palm of the hand they form a powerful shear or cutter, and may be made to serve
the useful purpose of cutting small wires, other articles, in addition to the use
or purposes to which the said two instruments are intended to be or are usually
applied. when forming part or parts of spring pocket knives as hitherto made and
generally known:
or
and
In order that my invention and the mode I prefer to adopt in carrying it into
effect may be fully and clearly understood, I have shown on the accompanying
sheets of explanatory drawings as examples, my improved combination pocket knife
and wire cutter in several different forms; the said sheets of drawings being
marked with figures and letters of reference corresponding with those in the
following description.
Figure 1 represents a pocket knife containing one cutting knife blade, a cork-
screw, and a combination screw driver, file, paper knife, and wire cutter, the wire
cutter being shown open ready for use, the said combination screw driver etc.
forming the lever arm, open at a convenient angle for grasping in the hand when
using the shear or cutter.
Figure 2 represents the same knife with the lever arm fully open as when in use
as a screw driver, file, or paper knife.
Figure 3 is one blade of the same knife, which blade forms the paper knife A,
file B, screw driver C; and the elongated and shaped end D beyond the pivot
hole E, forms one half of the wire cutter.
Figure 4 represents the bottom scale or side of the knife handle S, with the
end F shaped somewhat in the form of a claw, crescent, or hook, which end is
ground to a cutting edge on the outer side and forms the half of a shear or cutter
corresponding to and to operate in conjunction with the half of shear or cutter, D.
Fig. 3, in the operation of cutting or nipping.
Figure 5 represents the fastening which I prefer to adopt in this knife but any
other suitable fastening or spring may be employed. G is a spring, one end of
which rests upon the shoulder H of the cutter arm or blade A to impart automatic
opening action thereto. I is a pawl or catch actuated by the spring J and engages
and secures the lever arm A in position when closed. In order to release the
lever A and place the jaws D and F of the cutter in a suitable position ready for
use, the knife is held in the palm of the hand, and the projecting part K of the
pawl I is pulled towards the hand by the top of the thumb, or thumb nail, when the
lever blade or arm A immediately opens automatically by the action of the spring G
which. presses on to the shoulder H.
Figure 6 represents the back view of the spring G, Fig. 5, with the end L cut
away in order to allow the shaped end D of the shear or cutter blade (at the pivot
end of the lever arm A Fig. 5,) to pass between the spring G and the scale of the

page_text: knife S, Fig. 5, in the action of opening the lever arm or blade A straight out, as
shown at Fig. 2, for the purpose of using the said lever arm A as screw driver,
paper knife, or other instrument which it forms or may form.
Figure 7 represents a combined instrument knife and wire cutter, shear, or
nipper, in which the cutter is constructed independently of the scale or handle of
the knife. In this case the cutter is constructed in part with the file or other
instrument M, at the end farthest from the pin or rivet N which secures the file or
other instrument M in its place between the two scales S¹, forming the handle of
the knife in the usual manner. The file or arin M is constructed of sufficiently
strong steel to carry an arm or lever O which is loosely rivetted to the file M by
the pin or rivet E upon which it turns in the act of cutting or nipping. The cutter
is formed by the short ends of the file M, and the arm or lever O, beyond the rivet
or pin E, the whole of which can be neatly folded into the handle of the knife in the
same manner as an ordinary knife blade. The arm or lever O is shown as a button
hook O', but may be constructed to form paper knife, packing needle, cartridge
extractor, or other suitable instrument or instruments. A suitable spring G' may
be employed for the purpose of imparting automatic opening action to the lever
arm O. I sometimes construct this knife by securing the jaws of the cutter
between the two sides of the knife handle by the rivet N, and in this case the
arms M. & O which form a file and button hook or other instruments, are made to
open out in opposite directions from the knife handle, to act as levers for the cutter
or nipper.
Figure 8 represents a combined spring pocket knife, cigar cutter, and wire nipper
or cutter, of suitable size and thickness for carrying in the waistcoat pocket, and in
which both scales or sides of the knife P & Q are used to form the wire cutter
which is shown open, and in or about the middle of each of the two scales are holes
or apertures R & T for the reception of the end of the cigar which is cut by the
closing of the blade U in the usual manner.
Figure 9 represents the bottom scale and is preferably stamped or forged in one
piece with flanges or laps V & W, which are turned over on to the spring X Fig. 8,
and the blade U Fig. 8, and secured or fixed in position by rivets or pins in the
usual manner, the object of these flanges or laps being to provide clamps for the
spring X Fig..8, and blade U Fig. 8, and a washer or boss Y is secured to the flange
or clamp W, so as to form a raised surface or projection which enters the hole Z in
the scale Q, on the wire cutter being closed, thus forming a convenient fastening
both for the cutter and scale Q, and rendering the entire article fit and secure for
the pocket. In order to use the wire cutter, the thumb or finger nail is inserted
between the two scales P and Q so as to lift the scale Q and release it from the
washer or boss Y, when the scale Q is forced open by the action of the spring X.
The cutters or nippers herein described may be so ground, shaped, or con-
structed as to grasp and retain hold of the wire or nail after the operation of
cutting.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be or can be performed I would remark
that I am well aware that wire cutting instruments of small dimensions suitable for
carrying in the pocket have been previously made and patented both in England
and abroad, and I declare that what I claim in respect to the herein described
invention is
1. The adaptation to and combination with a spring pocket knife, of a wire
cutter, shear, or nipper, substantially as herein shown and described, and for the
purposes stated.
2. The new or improved pocket or instrument knife in which a wire nipping
shear or cutter is constructed in conjunction with and forms part of either an
ordinary cutting blade, a paper cutting blade, a cigar cutter or holder, a saw, a file,
a button hook, a fish hook disgorger, a packing needle, a cartridge extractor, or a
screw driver, in such manner that either one or two or more of the said instruments

page_text: are

forms
formed by or the lever arm or arms of the wire cutter or nipper sub
stantially as herein described and set forth with reference to the accompanying
drawings..
3. In spring pocket knives the construction, adaptation, and use of handles or
scales which are curved, crescent shaped, or somewhat claw shaped at one end,
substantially as herein described and set forth with reference to Fig. 4 of the
accompanying drawings and for the purpose specified.
4. The new or improved combination spring pocket knife, wire cutter, and cigar
cutter, in which the two sides or scales of the handle are constructed with curved
or somewhat claw or crescent shaped ends, which when loosely rivetted or pinned
together, form a cutter for securing or nipping small nails, pins, wire, etc. sub-
stantially as herein described with reference to Figures 8 and 9 of the accompanying
drawings.
