Improvements in Pliers and the like.
I, EDWARD FRANCIS DANIEL NEUFF, of 177 Newington Butts in the county of
Surrey, Scientific instrument maker, do hereby declare the nature of this invention
to be as follows :-
My invention refers to pliers and other instruments provided with jaws for nipping
or holding, such jaws according to my invention being always parallel to one another
whether open or closed.
According to one modification the handles or shanks may be jointed together in the
usual manner by a fulcrum rivet or otherwise and are provided with extensions. The
jaws are made separately and the upper parts thereof are jointed to the extensions of
the handles above or beyond the fulcrum rivet, whilst the lower parts of the jaws are
provided with slots in which move pins fixed or rivetted to the handles below the
fulcrum rivet.

COMPLETE SPECIFICATION.
Improvements in Pliers and the like.
I EDWARD FRANCIS DANIEL NEUFF of 177 Newington Butts in the County of
Surrey, Scientific Instrument Maker, 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 :-
My invention refers to pliers and other instruments provided with jaws for nipping
or holding such jaws according to my invention being always parallel to one another
whether open or closed.
According to this invention the handles or shanks which may be jointed together in
the usual manner by a fulcrum rivet or otherwise are provided with extensions. The
jaws are made separately and the upper parts thereof are jointed to the extensions of
the handles above or beyond the fulcrum rivet whilst the lower parts of the jaws are
provided with slots in which move pins fixed or rivetted to the handles below the
fulcrum rivet.
Figure 1 of the accompanying drawings illustrates the invention as applied to a
pair of pliers the handles being so formed as shown in dotted lines but this part of
the instrument forms no part of my invention and the handles may be made in any
desired or usual form according to the numerous uses to which instruments with
parallel jaws are applicable from large smithy tongs to the finest tongs or pliers for
use in the trade of watchmakers, optical and surgical instrument makers and others.
The handles or shanks A are jointed together by a rivet B and are formed with
extensions A¹.
The jaws C are made separately and their upper parts are by the rivets D jointed
to the handle extension A¹ above or beyond the fulcrum rivet B whilst the lower
parts of the jaws C are provided with slots in which move pins E fixed or rivetted
to the handles A below the fulcrum rivet B. One of the jaws C is, as shown at
Fig. 2, fork-shaped where it fits over the shank, which is or may be here reduced in
thickness while the other jaw in this place, as shown in Fig. 3, is reduced in thickness
and fits in a slot formed in the corresponding handle or shank.

In Fig. 4 is shown another form of instrument in which the extensions A' are made
with a set off, as shown in Fig. 5, and their joint ends working in recesses or between
lugs formed on the jaws C. One of these latter is also formed with set-off, as shown
in Fig. 6. The handles may also, in this case, he made in any desired or usual
form.
The nipping surfaces of the jaws may, in all cases, be flat, as shown, and plain or
grooved, or it may be made of any other shape hollowed out or otherwise according
to the numerous uses such instruments are made for.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. Pliers, tongs or similar instruments for gripping and holding articles between
jaws which latter are made separate from the shanks and jointed to extensions of same
and provided with slots for rivets on the shanks to work in so as to ensure that the
gripping surfaces of the jaws are parallel in all positions substantially as set forth.
2. The constructions of pliers or tongs shown on the drawings.
