CHARLES JUNGE, of 132, Rotherfield Street, Essex Road, Islington, in the
County of Middlesex, Engineer. "A UNIVERSAL VICE."
The features of novelty which constitute my Invention relate to the arrangement
and construction of a simple and efficient parallel vice for holding articles of any
shape, regular and irregular, which may occur in practice.
All vices hitherto constructed fulfill their object but insufficiently. Parallel vices
being mostly of a very complicated nature and difficult to manufacture necessitate
an enormously high price. These cases are successfully met by the present con-
trivance, which differs advantageously from others by its manifold application and
great simplicity of arrangement combined with strength. An illustration is shown
in the accompanying Drawing, to which reference is made in the following
description:-
This new parallel vice is almost wholly made of wrought-iron, and consists of
two side-bars A, A, which are provided with a rolled or planed groove running
from end to end for guiding a movable slide B. To the front-part of the side-bars
is fastened by means of rivets a fixed jaw C, whose prolongation downwards forms
the tail, which is bolted to the bench and supports the vice. The front C and the
back I (part of the latter being shaped into a wing L secured to the bench) take
up a screw K, which passing through the sockets M, N, belonging to the slide B
causes the movement of the latter. On the top of the slide B a double-jaw D, E,
which is a combination of an ordinary jaw D and a self-acting jaw E, is mounted
in a dove-tail fashion, and prevented from shifting out of place by a bolt F, as
shown in Fig. 1 & 3. Fig. 2 represents a section on line O, P. Another and
simpler arrangement for fastening the double-jaw D, E, to the slide B is shown in
Fig. 4 & 5, where this is obtained by a screw S with a washer being fastened to a
piece protruding upwards from the centre of the slide. By putting the jaw D
towards the fixed jaw C, as shown in Fig. 1, the work of an ordinary vice may be
performed, whilst if E is placed towards C, as illustrated in Fig. 3, any regularly
and irregularly shaped article may be firmly held by this vice. The new self-
acting jaw E being capable of turning horizontally around G assumes the position
required for fixing any article as soon as it is brought into contact with the same,
and by removing the screw H may, without loss of time, be easily replaced by any.

vices, and I also employ instead of the double-jaw D, E, both D and E seperately,
in which case they are made in one piece with the slide B, of which arrangement
Fig. 6 gives an illustration.
Having thus described my Invention, I claim as new and desire to secure by
Letters Patent,―
First. The arrangement of the side-bars A, A, containing rolled or planed
grooves (shown in section in Fig. 2) for guiding the travelling-jaw.
Second. The peculiar construction of the self-acting jaw E rendering this vice
universally applicable, and which can be substituted by any jaw of different
shape.
Thirdly. The self-acting jaw in connection with an ordinary jaw, which com-
bination has for its object to provide in this vice universal application and the
strength of a vice of the common type.
Fourthly. The sole right of application of the self-acting jaw to other vices with
or without the ordinary jaw.
