PROVISIONAL SPECIFICATION.
Improved Combination Knife, Containing Pliers and Tyre Lifting
Appliance, Specially Adapted for Cyclists' Use.
I, JOHN ROBERT WATTS, of Lambert Street in the City of Sheffield, Cutlery
Manufacturer, do hereby declaro the nature of this invention to be as follows:-
This invention relates to pocket or spring knives, and has for its object the
production in one implement a combination of appliances to enable a cyclist to
adjust various parts of a cycle such as nuts, air valve fittings, spokes and the liko,
also for lifting pneumatic or other elastic tyres out of the groove or rim of the
wheels of road vehicles, thereby obviating the necessity for carrying other tools for
these purposes in addition to my improved knife.
In carrying out my invention, I make one of the scales or sides, usually forming
the body of such a knife, of steel sufficiently strong to form one jaw of the pliers
and long enough to project beyond the end of the knifo proper, and inside of the
knife I fit a corresponding jaw pivotted in the usual manner having an extension
which operates as a lever for applying the necessary gripping force by the operators
hand, the said lever part when not required for use lays within the body of the knife
and is retained in the closed position by nieans of a catch or other equivalent device:
the lever itself being fitted against a spring to keep the lever open or in an extended
position when released.
On the opposite side of the knife, I insert a specially shaped implement or blunt
blade constituting the tyre lifting appliance which, when closed, I prefer to leave the
curved ond thereof slightly projecting above the scale or body of the knife through
an opening specially formed in the outer scale for that purpose.
The knife proper may have in addition any desired number of blades,
pricker, corkscrew or other appliances usually forming part of pocket or spring
knives.

pliers and also my new tyre lifting instrument in addition to several other impliments
usually found in an ordinary knife All the several instruments are shown partially
opened out;
Fig. 2 is an edge view of the moveable part constituting the pliers:
Fig. 3 is likewise an edge view of the tyre lifter.
I make one end of one of the scales or sides, a, (usually forming the body of such a
knife) of steel sufficiently strong to form one jaw, a', of the pliers and long enough
to project beyond the end of the knife proper, and inside of the knife I fit a
corresponding jaw, b, pivotted in the usual manner having an extension, c, which
operates as a lever for applying the necessary gripping force by the operators hand,
the said lever part when not required for use lays within the body of the knife and is
retained by means of a catch or other equivalent device: the lever itself being
fitted against a spring to keep said lover open or in an extended position when
released.
On the opposite side of the knife I insert a specially shaped implement or blunt
blade, d, the edges whereof are well rounded off constituting the tyre lifting
appliance, which when closed I prefer to leave with the curved end thereof slightly
projecting above the scale or body, a, of the knife through a side opening, e, specially
forined in the scales for the purpose of easy stowing and opening.
The knife proper may have in addition any desired number of blades such as,
k, corkscrew, s pricker or other like appliances usually forming part of pocket or spring
knives.
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 :-
1st. With a pocket or spring knife the addition to and combination therewith of an
extended scale, a, and a lever, c, with jaw, a', together constituting a pair of pliers
constructed substantially as hereinbefore described and illustrated.
2nd. With a pocket or spring knife the addition to and combination therewith of a
blunt instrument, d, specially curved and shaped to operate as cycle tyre lifter, said
instrument when closed laying away in a special opening formed through knife
