PROVISIONAL SPECIFICATION.
Improvement in Tongs for Coal and other Substances.
JOSEPH PETER FUNT, of No. 2 Duncan Terrace, Islington, London N. do
bereby declare the nature of this invention to be as follows:-
The tongs consist of a handle, with two legs hinged to the handle in the ordinary
way. The handle forms a cross bar instead of ending as usual in a knob or point.
At about one third of the distance between the hinges and the other end of the
legs are hinged two levers, which meet in the centre between the legs and are
there hinged to a bar, which is in the form of a "T" and which T-bar is hinged
at its lower extremity to the said two levers. The upright of said T-bar, passes
through a hole in handle of tongs between hinges of legs, and the cross piece of
said T bar, slides inside handle so as to be readily grasped by the hand in conjunc-
tion with said cross-bar of handle and so closing legs of tongs, and thus grasping
firmly and without any strain on the hand, coal or other substance which it may
be desired to pick up with the tongs.
A spiral spring is provided which encloses upright of T-bar in order to keep
the legs of tongs open and ready for use.

I, JOSEPH PETER FUNT formerly of 2 Duncan Terrace, Islington London N.
and now of Clovelly Mansions, Gray's Inn Road, London W.C., Agent do hereby
declare the nature of this invention, and in what manner the same
performed, to be particularly described and ascertained in and by the following
statement :-
is to be
My invention relates to an improvement in tongs for picking up lumps of coal
or other substance, and it has for its object to facilitate the manipulation of the
tongs and enable a large and heavy lump of coal to be grasped more firmly and
with a less stretch of the fingers and therefore with less strain on the hand than
when the limbs of the tongs are pressed directly together in the ordinary way.
The invention is illustrated in the accompanying drawing, formning part of this
Specification, which represents the tongs in the open position in full lines and in
the nearly closed position in dotted lines.
The invention consists essentially in the combination, with the hinged limbs A, A,
and handle B, of the tongs, of a toggle motion consisting of the links C. C worked
by a cross-head D connected to the toggle links by a rod d and sliding in the
shank of the handle B in such position as to permit it to be grasped by the fingers
of the band in which the fixed T-head B' of the handle is held, and be drawn
towards such T-head for the purpose of closing together the gripping jaws E, E,
of the limbs A, a spiral spring F being applied to act on the sliding cross-head in
the opposite direction for the purpose of opening the jaws. The limbs A are
pivoted at a to the handle in the usual way and the toggle links C are pivoted to

page_text: the limbs A at c and to each other and to the sliding rod dat d'. The rod d
passes through a guide hole in the boss or body portion B2 into the shank B of the
handle which is tubular and has a longitudinal slot b at either side to give passage
to the sliding cross-head D whose projecting portions are suitably curvel to form
finger grips, as shewn. The spiral spring F is contained within the tubular handle
and is compressed between the sliding cross-head D and the outer end of the
handle B which is closed by the T-shaped cross-head B' secured by a set screw or
otherwise. The gripping jaws E are pivoted to the limbs of the tongs at e to
enable them to be self-adjusting to lumps of different sizes, and are furnished on
their gripping faces with teeth to enable a good hold to be obtained.
G is a
pivoted hooked link for holding the tongs closed when not in use.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
The combination, with a coal or other tongs, of a toggle motion connected to the
limbs of the tongз and to a sliding cross-head working in the handle and operating
in such manner as to cause the tongs to be closed by an upward movement of the
sliding cross-head.
2. The combination, with a tonga provided with a T-headed tubular handle, of
a toggle motion connected to the limbs of the tongs and to a rod sliding through
the tubular handle and provided with a finger grip cross-head, and of a spring on
the sliding cross-head, as specified.
3. The herein described improved tongs substantially as specified.
