PROVISIONAL SPECIFICATION.
Improvements in Wire Strainers.
JOHN HENRY HARBADINE, 13 Lyndhurst Street Derby, Telegraph Inspector,
do hereby declare the nature of this invention to be as follows:-
In an improved form of Dutch tong, in conjunction-or otherwise with the ratchet
portion of the usual form of draw vice, used for straining up telegraph wires or for
other purposes.
In order to effect this I provide an oblong, or other suitably shaped base-plate,
slotted at one end, and carrying upon its opposite end two independent plates or
"wings" of a suitable shape, working on independent centres side by side (or so
arranged as to work on one common centre) and provided with a slot at their
extremity at which point I couple by a stud or tubular arrangement the said
"wing" pieces to an angular piece, which at its intersecting angle is, by the aid of
a stud, free to move within the slot of the base plate.
At a suitable point in each of the said "wings" I fix a triangular or other shaped
piece for the purpose of holding the wire to be strained, and I arrange this so that
on changing the faces of the said piece, or pieces, it will accommodate itself to
various gauges of wire.
The principle upon which the tool thus arranged works, affords a perfectly
parallel grip of the wire, and distributes the strain which the tool has to bear,
evenly on either side.
When so required I connect the instrument to the usual ratchet arrangement of
draw-vice generally employed for regulating wires, so that the two parts-the
ratchet and the Dutch tongs-may form one compact and convenient tool.

JOHN HENRY Harradine, 13, Lyndhurst Street, Derby, Telegraph Inspector,
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 consists of an improved form of Dutch tong that may be used with,
or without, the ratchet portion of the usual form of draw vice for straining up
telegraph wires or for other purposes.
Fig. 1 shows the improved Dutch tong and in Fig. 2 it is coupled to the ratchet
portion of the usual form of draw-vice.
The "wing" pieces B. B¹ are attached to base plate A by means of studs 6 h²-
the said "wing" pieces being free to move round their points of attachment-at
the opposite ends of A. B. BT slots are provided as shown at s. s. 8.
The angular
piece C. C. is connected to B and B by studs at c. c and to A by stud e. the said
studs c. c and e being free to move within the slots s. s. s.
In Fig. 1 triangular pieces are attached to B and B by means of studs d. d¹ the
said triangular pieces being free to turn around the studs which connect them to
the wing pieces. The sides of D. D' (which form the jaws of the wire strainer) are
grooved and milled for the purpose of holding the wire to be strained.

page_text: When coupled to the ratchet arrangement as shown in Fig. 2. loop E is replaced
by any suitable shaped piece.
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. A parallel grip of the wire or wires to be strained between D. D' without
undue pressure.
2. That by using triangular or other shaped pieces at D. D³ the tool may be
used for various gauges of wire.
Dated this 5th day of March 1894.
