Complete Specification Left, 19th Mar, 1896-Accepted, 25th Apr., 1896
I, JOSEF FLURY, of Horgen, in the Republic of Switzerland, Constructor,
do hereby declare the nature of this invention to be as follows:-
This relates to an improved construction of parallel vice, applicable both to hand
vices and to fixed vices.
The improved vice consists essentially of two jaws made of any suitable section
and each having a longitudinal slot or recess on its inner face. In one end of each
of these slots is pivotted an arm, the two arms being pivotted together at or about
the centre of their lengths and their free ends sliding in the slots or recesses in the
jaws the free end of each arm sliding in the slot or recess in the opposite jaw to
that to which it is pivotted. The jaws are operated by a right and left hand screw
spindle threaded into the two jaws and adapted to be operated in the well-known
manner.
If the vice is intended to be a fixed one, it may be adapted to be fixed to the
bench or the like in any convenient manner, and as an alternative construction
the jaws may be operated by a single screw.
Owing to the arrangement of the cross arms the parallel movement of the jaws
is insured which permits the greatest amount of gripping force to be obtained.

I, JOSEF FLURY of Horgen, in the Republic of Switzerland, Constructor,
do bereby 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:-
This relates to an improved construction of parallel vice, applicable both to hand
vices and to fixed vices."
The accompanying drawing is a view in side elevation of a vice constructed
according to this invention.
The improved vice consists essentially of two jaws X X made of any suitable
section-preferably of the section shown on the right hand jaw of the accom-
panying drawing and each having a longitudinal groove or channel S in its inner
face. In one end of each of these grooves or channels S is pivotted at A. an
arm Y, the two arms being arranged to cross each other and to be pivotted together
at or about the centre of their lengths, their free ends D being adapted to slide
freely in the grooves or channels S in the jaws, the free end D of each arm sliding
in the groove or channel in the opposite jaw to that to which it is pivotted. The
jaws are operated by a right and left hand screw spindle Z threaded into the two
jaws X X and adapted to be operated in the well-known manner.

page_text: If the vice is intended to be a fixed one, it may be adapted to be fixed to the
bench or the like in any convenient manner, and as an alternative construction
the jaws may be operated by either a right or a left hand screw spindle.
Owing to the arrangement of the cross arms the parallel movement of the jaws
is insured which permits the greatest amount of gripping force to be obtained.
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 :-
A parallel vice, the parallel movement of the jaws of which is assured by two
arms crossing each other and pivotted at their point of intersection, one extremity
of each arm being also pivotted to one of the jaws and the free end being adapted
to slide in the groove or channel formed in the opposite jaw to which it is pivotted,
substantially as hereinbefore described and shown.
