COMPLETE SPECIFICATION.
Vice.
I, EBERHARDT WÜNNENBERG, Engineer of Cologne on the Rhine, Bobstreet
No. 20, 1st Floor, in the Province of Rhineland, Germany, 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:-
The invention is represented in
Fig. 1 in a front-view with the front cover partially removed,
Fig. 2 in side-view,
Fig. 34 in a section in the longitudinal direction of the cheeks towards u—v,
Fig. 4 in a cross-section towards w-x,
Fig. 5 in an upper view with the upper cover removed and partially in section
towards w2.
Fig. 3 is a cross-section through the support of the vice that is at any time
removable with upper view of the socket forming the guide for the support.
In Fig. 1 socket and support are omitted, that is the vice is drawn in a case of
never leaving its position, thus immovably fixed to the bench from the beginning.
It is fastened in this way by means of the screws, which must be driven through
the holes a of the flaps which are forged on behind the vice. The screw-flaps may
of course be wanting in the vice that is at any time removable, as drawn in
Fig. 4, but are better retained, as is done in the rest of the figures, in order to save
models.
The chief difference of the new vice in contrast to all hitherto invented is in the
fact that instead of the one spindle hitherto used for the guidance of the cheeks,
two (or according to need three and more) spindles are employed, by which means
the possibility of making the cheeks as long as is desired, a tension of the checks,
that is always equal, a large opening and exact parallel guidance is attained.
The latter is easily obtainable not only for vices with beaded or planed guides, but
also for the common simple (spring) vices. In my construction the grip occurs
between the spindles whilst in the vices with one spindle only to one side of the
spindle, so that in this case there is a likelihood of a bending or twisting or tipping
over; this is however completely avoided in my construction.
The whole vice is fitted on the foot-plate A, which rests either on the bench or
on the support fastened to the bench, and consists of the front cheek D and the
back cheek E, which towards the back widens into a guide or anvil-plate and at
the same time serves as upper cover for the horizontally sliding parts.
The front cheek D has on the inner side of its vertical part two horizontal
projections 9 g in the shape of tubes open below of a horse-shoe like section, which
when the cheek D is moved, slide in grooves h h on the upper side of the foot-
plate A. At the front end of these grooves two longitudinal collars i i are attached
which are fitted on to the inner space of the projections g g and which are per-
forated through their length and are provided with an inner screw-thread, so that
they serve as nuts for the screw-spindles k k lying inside the tubes and fastened
at their further end by nuts.

These screw-spindles are fastened so as to be able to turn to the vertical piece
of the cheek D, and project beyond it with their exterior end. Both the screw-
spindles kk are set in motion by gearing from a centre-shaft m by means of a
removable hand-crank n, as shewn in the drawing, or by a sliding hand-crank, as
is usual with vices, and thus the motion of the cheek D towards the fixed cheek E
is effected. The transmission from the centre-shaft m to the screw-spindles k k is
generally effected direct by a toothed-wheel o attached to the centre-shalt m, and

page_text: which catches in the toothed-wheels p p, situated on the square ends of the
spindles kk, projecting outwards in front of the vertical part of the cheek D.
But if, as is always the case when the distance from each other of the
spindles kk is too great, the toothed-wheels in reality would get too great
dimensions for a direct gearing together, the impulse must be made indirectly,
either by further auxiliary toothed-wheels, inserted between the toothed-
wheels P o, p, or by an endless link-chain, or by a transverse shaft driven by
conical wheel-work from the centre-shaft m, and which catches at each end with a
worm in the toothed-wheels pp, which in that case must be formed as worm-wheels.
The driving mechanism on the front vertical side of the cheek D is covered by a
cover 9 attached by screws, allowing the driving-peg of m to pass through in the
centre, and it is thus protected against injuries, dirt and dust.
The fixed cheek E lies with corresponding notches over the tube-shaped
projections 9 9 and is shaped towards the back as a table or anvil-plate F, containing
on the lower side guide-grooves for the longitudinal bands rr lying on the top of
the tubes gg (Figs. 3 & 6), and resting with its front-, side- and back-edge on the
foot-plate A, and fastened to it by the screws $ 8. The back-edge of the plate F
also catches in a groove-shaped hollow t of the foot-plate A, so that the screws & s
are relieved. The lower side of the anvil or straightening-plate F can also be
stiffened and supported by ribs resting on the ground-plate A between the guides
of the front cheek.
If such a vice is not permanently to be fixed to the bench, but at need to be
taken off, placed high or low, or if the direction of the mouth to the bench is to be
altered, a cylindrical foot-support B is attached to the lower side of the foot-plate A
and rests in a socket C, that is firmly attached at its upper and lower end by means
of the screws ff to the bench, and able as well to slide vertically in this socket
as also to revolve about the vertical axis. The support B is provided at the top
close under the foot-plate A with a disk or plate b, having at the bottom one
or more projections d d (Fig. 3A) in the form of pegs, teeth etc. These projections
catch into corresponding holes e e (Fig. 3B) arranged in a circle, or into notches
cut into the margin of a collar c forming the upper part of the socket C.
If the vice is now turned about the vertical axis of the support, it can in every
radial position be secured against further undesired twisting by the catching in of
the projections d d into the holes e e. But this is only the case as long as the vice
remains in a level with the height of the bench. But if, on the contrary, it is
raised by moving the support B in the socket C in a vertical direction, the vice
is secured as well against a further moving in height as against a turning round by
one or more thumb-screws 1. But the collar c may also lie loose on the socket C
and slide on it vertically by means of rails, 30 as to serve at any height to secure
the vice against turning about its vertical axis. In order to make the up and down
motion of the vice easier the support C may also have screw-threads or be formed
as a cylindrical toothed-bar and driven by a suitable mechanism. By thus stopping
the driving-gear an absolutely secure fixing of the vice at any height is at the
same time obtained.
If some other work is to be done on the bench so that the vice would be
in the way, it can be lifted with the foot B entirely out of the socket C and
taken away.
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 :
1. Vice with cheeks of any length and opening of any size desired, distinguished
by the moving of the front check of the vice D by means of two or more spindles k k
placed at any distance from each other and set in motion by a single driving-gear m,
as well as by the formation of the hinder cheek of the vice E towards the back
into an anvil or straightening-plate F, resting with its heightened margin all

page_text: round on the foot-plate A, and containing in the hollow thus formed the guides of
the front cheek.
2. In connexion with this vice a bed which allows of the vice to be moved
vertically at will and to turn horizontally about a vertical axis, distinguished by the
support B, resting in a socket C in connexion with the stopping-mechanism acting
by means of the catching in of projections d d on the lower side of the vice into
corresponding holes e e on the upper margin of the socket C.
