An Improved Vice.
I, CHARLES BAUER, of 11, Comerford Road, Brockley, Kent, Engineer, do
hereby declare the nature of the said invention to be as follows
This invention relates to an improved vice for gripping and holding rods or
tubes of metal or other material while being screw-threaded, cut or otherwise
manipulated.
Especial objects of the invention are to avoid the disadvantages attendant upon
ordinary vices the jaws of which require to be opened by hand to admit of the
rod or tube being placed between them, and to produce a vice the jaws of which
will automatically open to admit of the rod or tube being placed between them
upon the rod or tube being borne thereagainst in the act of lowering or placing
it in position.
In carrying out the invention, I pivotally support, at the upper parts of two
oppositely arranged pairs of standards rising from a common base, two oppositely
arranged gripping jaws in such a manner that they depend from their respective
pivots, preferably overlapping each other to some extent but with a sufficient
clearance to freely pass each other.
The gripping edges of the jaws are so shaped as to be tangential to the surface
of rods and tubes of all diameters within the compass of the vice, and are oppositely
serrated so as to securely hold the rod or tube whichever way the manipulation of
the latter should tend to turn it.
The top edges of the jaws, above the point where the gripping edges are adapted
to hold rods and tubes of the maximum diameter within the compass of the vice,
are disposed horizontally or approximately so, so that on the rod or tube being
lowered thereonto the weight thereof and consequent leverage on the jaws will
cause the latter to open against the closing resistance of their respective springs
and to admit of the descent or placing of the rod or tube onto the channelled bed of
the vice, whereupon, said springs will immediately effect the closing of the jaws
upon the opposite sides of the rod or tube to those supported by the vice bed.
The top edges of the jaws, on the outer sides of their axes may be formed or
provided with extensions so arranged that by pressing the same towards each other
the jaws may be opened to admit of the finished rod or tube being removed from
the vice.
The outer sides of the jaws, adjacent to their centres of motion, may be formed
or provided with projecting stops adapted to abut against the outer sides of the
standards to limit the inward or closing movement of the jaws, which may also be
effected by adapting the lower edges of the jaws to abut against the channel of
the bed.
To facilitate the placing of the jaws and of the springs by which they are closed,
the jaws are mounted on oppositely arranged pivot pins which are screwed into the
standards.
The vice may also be fitted at one or both sides (in the direction or line of a rod
or tube resting on its channelled bed) with serrated cams adapted to offer a
resistance to any end thrust or pull of the rod or tube being screw-threaded, cut or
otherwise manipulated, such cams being pivoted in lugs projecting from the side or
ides of the vice bed, and being normally caused to occupy a raised position by
prings adapted to their pivots, and being automatically depressed into their

COMPLETE SPECIFICATION.
An Improved Vice.
I, CHARLES BAUER, of 11, Comerford Road, Brockley, Kent, Engineer, do
hereby declare the nature of the said invention, and in what manner the same.
is. to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention relates to an improved vice for gripping and holding rods or
tubes of metal or other material while being screw-threaded, cut or otherwise
manipulated.
Especial objects of the invention are to avoid the disadvantages. attendant upon
ordinary vices the jaws of which require to be opened by hand to admit of the rod
or tube being placed between them, and to produce a vice the jaws of which will.
automatically open to admit of the rod or tube being placed between them upon,
the rod or tube being borne thereagainst in the act of lowering or placing it in
position.
On the accompanying drawings
Fig. 1, represents the improved vice in side elevation, partly in section.
Fig. 2, represents the same in end elevation.
Fig. 3, represents the same in plan view.
Fig. 4, represents a side elevation of the rice, showing the same as. gripping
a tube.
Fig. 5, represents an end elevation of Fig. 4.
In carrying out the invention, I pivotally support, as at 6, at the upper parts of
two oppositely arranged pairs of standards 7, rising from a common base 8, two
oppositely arranged gripping jaws 9, in such a manner that they depend from their
respective pivots 6, preferably overlapping each other to some extent and having,
a sufficient clearance to freely pass each other. The jaws may, however, not
overlap, and in such event they may be situated opposite to each other.
The gripping edges of the jaws are so shaped as to be tangential to the surface
of rods and tubes of all diameters within the compass of the vice, and are oppositely
serrated so as to securely hold the rod or tube 11, (vide Fig. 4.) whichever way, the
manipulation of the latter should tend to turn it.
The top edges 12, of the jaws, above the points 13, where the gripping edges. are
adapted to hold rods and tubes of the maximum diameter within the compass.of.the
vice, are disposed horizontally or approximately so, so that on the rod or tube
being lowered thereonto (ride the dotted lines Fig. 1.) the weight thereof.or any,
pressure thereof if not sufficiently weighty and consequent leverage on the jaws,
will cause the latter to open against the closing resistance of their respective
springs 14, and to admit of the descent or placing of the rod or tube onto the
channelled bed 15, of the vice, whereupon, said springs will immediately. effect. the
closing of the jaws upon the opposite sides of the rod.or tube to those supported: by
the vice-bed. Vide Fig. 4.
The top edges of the jaws, on the outer sides of their axes, are or-may be formed
or provided with extensions. 16, so arranged that by pressing the same towards each
other by the hand, the jaws. may be opened to admit of the finished rod, or, tube.
being removed from the vice.
The outer sides of the jaws, adjacent to their centres of motion, are or, may, be
formed or provided with projecting stops. 17, adapted: to, abut against the outer.

page_text: sides of the standards (vide Fig. 1,) to limit the inward or closing movements of the
jaws, which may also be effected by adapting the lower edges of the jaws to abut
against the channelled bed 15, vide Fig. 1.
To facilitate the placing of the jaws and of the springs 14, by which they are
closed, the jaws are mounted on oppositely arranged pivot pins 6, which are screwed
into the standards, and each spring is entered the one end into its jaw and the other
end into its pivot pin 6, by turning which the closing power of the spring may be
augmented, lessened or set, as required. Or, each pin 6. may be rivetted in position,
the spring ends being respectively entered into the adjacent jaw and standard.
The vice may also be fitted at one or both sides (in the direction or line of a rod
or tube resting on its channelled bed) with serrated cams 18, adapted to offer a
resistance to any end thrust or pull of the rod or tube being screw-threaded, cut or
otherwise manipulated while in the vice, such cams being pivoted on pins 19,
screwed into opposite lugs 20, projecting from the side or sides of the vice-bed,
and being normally caused to occupy a raised position (vide Fig. 2,) by springs 21,
entered thereinto and into their pivot pins 19, and bearing the same against a
convenient stop 22, and being automatically depressed into their gripping position
(vide Fig. 4,) by the lowering or placing of the rod or tube into position between
the jaws 9, and on to the channelled bed of the vice. Or, the pins 19, may be
rivetted in position and the spring ends respectively entered into the adjacent cam
and lug.
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 :-
1. The improved vice hereinbefore described with reference to the accompanying
drawings.
2. In a vice, the combination of two oppositely arranged gripping jaws (such
as 9.) depending from pivotal supports and adapted to automatically open and
operate substantially in the manner hereinbefore described.
3. The formation of such jaws with extensions 16, adapted to open the jaws to
admit of the finished article being removed from the vice.
4. The application to a vice of serrated cams (such as 18,) adapted to prevent
endway movement of the rod or article being manipulated in the vice.
