Improvements in Screw vices,
I, NICOL OTTO, of Dorfstrasse 77, Merchingen bei Merzig a/S., in the Empire of
Germany, Engineer, 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, and accompanying drawing that is to say:-
Screw vices ordinarily heretofore used are generally fixed, or if adjustable can
be moved in one plane only round a centre. Moreover, such ordinary screw vices
are fixed in a horizontal position only and it is therefore necessary, in order to
bring the article which is held to be worked at into any other position, to intro-
duce a suitable packing or support specially made for the purpose.
The object of the present invention is by a novel and simple construction to be
able to turn the entire vice and bring it into the desired position, so that, for
instance, long gaspipes and the like can be fixed and operated on, without any
special appliance. The vice is especially suitable for small workshops, as by its
means on account of the facility for turning it into any position, long objects can
be worked upon in a position which in ordinary screw vices is either impossible,
or can only be effected with very great difficulty, as in small locksmiths' or
turners' workshops. Another great advantage of the improved screw vice is in
dark workshops, and where work has to be done in the dusk of evening, as the
work can be turned into the best position to receive what light there is available.
The accompanying drawing is in illustration of the invention.
Figure 1 is a section through the screw vice in its horizontal position:--and
Figure 2 is a side view of the same, turned to an angle of 90° from Figure 1.
As shown in Figure 1, the screw vice a is firmly fixed to a hollow spherical
attachment b, by means of a flange. The hollow spherical piece has a hole c
through it from the flange, and its spherical part is provided with cross slits d,
which serve as guides for a bolt f the head of which is passed through the hole c
in the flange, so that the screw vice is capable of being turned round on the
bolt. To allow such turning of the vice, the spherical part fits into a corres-
ponding spherical recess in a projection h formed upon the main plate y upon
which the screw vice is carried, so that a movement of the latter in the recess h
in
any direction is possible, whilst the two can be firmly held together when the
position has been adjusted as desired.
The bolt passes through a corresponding opening in the recessed projection h,
and has upon its outer end a screw thread to receive a corresponding nut i, by
which after the required position has been adjusted, the sphere is firmly held
in the corresponding spherical recess in h.
When it is required to adjust the vice to another position, it is only necessary
to slacken the nut i, when the vice becomes freely moveable.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is;-
-
1 A screw vice having a spherical attachment fitting in a corresponding recess

page_text: in the main supporting plate g so that the screw vice a can be moved into any
desired position.
2. In a screw vice made according to Claim 1, the spherical piece
attached
to the vice, and having slits d, and fitting in a corresponding spherical recess
in the projection h upon the supporting plate g, so as to be adjustable in any
desired position.
3. In a screw vice made according to Claims 1 and 2, the bolt f the head of
which e is introduced into the hollow spherical attachment 6 through the hole c,
so that the screw vice can be adjusted into any desired position, being securely
guided by the cross slits upon the bolt f.
4. In a screw vice constructed according to Claims 1, 2, and 3, the nut i fitting
upon a screw thread upon the bolt f, in order to hold the vice a firmly in any
position to which it has been adjusted.
All substantially as described and illustrated.
