Complete Specification Accepted, 17th Aug., 1888
I, PAULINE HORTENSE GONTARD of Montbéliard in the Republic of France,
Jeweller, do hereby declare the nature of this invention, to be as follows :-
This invention refers to vices and is applicable principally to such vices as comprise
a fixed jaw and a movable jaw having a sliding bar supported in or by the fixed jaw,
so that the movable jaw may be accurately and properly guided in relation to the fixed
jaw by a screw threaded spindle.
The improvement consists in so arranging the said screw threaded spindle for
operating the movable jaw that it may act centrally with regard to the bearing
surfaces of the aforesaid sliding bar of the movable jaw so that the latter may slide
freely when moved by said spindle.
Thus the foot of the fixed jaw may be suitably extended to support the base of
the sliding bar, the latter passing through the fixed jaw and the upper part of the
said sliding bar may be provided with flanges bearing in the fixed jaw, the spindle
operating the relative displacement of the jaws being under said flanges and above
the base of the sliding bar.
Such a vice may be fixed to a bench, table or the like by screws or bolts passing
through flanges on the foot of the fixed jaw, or it may be arranged as a swivel vice
by making the foot of the fixed jaw circular and supporting it upon a circular
rail or flange, fastened to the bench or the like, the vice being secured by a bolt
passing down through the bench and adapted to fix the vice down upon the rail
or flange.

page_text: I PAULINE HORTENSE GONTARD of Montbéliard in the Republic of France,
jeweller 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 :-
This invention refers to vices and is applicable principally to such vices as comprise
a fixed jaw and a movable jaw having a sliding bar supported in or by the fixed jaw
so that the movable jaw may be accurately and properly guided in relation to the
fixed jaw by a screw threaded spindle.
The improvement consists in so arranging the said screw threaded spindle for
operating the movable jaw that it may act centrally with regard to the bearing surfaces
of the aforesaid sliding bar of the movable jaw, so that the latter may slide freely when
moved by said spindle.
Thus the foot of the fixed jaw may be suitably extended to support the base of the
sliding bar the latter passing through the fixed jaw and the upper part of the said
sliding bar may be provided with flanges bearing also in the fixed jaw the spindlo
operating the relative displacement of the jaws being under said flanges and above
the base of the sliding bar.
Such a vice may be fixed to a bench, table or the like by screws, or bolts, passing
through flanges on the foot of the fixed jaw, or it may be arranged as a swivel vice by
making the foot of the fixed jaw circular and supporting it upon a circular rail or
flange fastened to the bench or the like, the vice being secured by a bolt passing
through the bench and adapted to fix the vice down upon the rail or flange.
Referring to the accompanying drawings:
-
Fig. 1 is a side elevation of my improved vice and Fig. 2 a cross section thereof.
Figs. 3 and 4 are similar side elevation and cross section respectively of a slightly
modified form of vice.
Fig. 5 is a plan view of the fixed base or rail for the vice when constructed as a
swivel vice.
A is the fixed jaw supported upon a base plate having three perforated lugs by
which it may be fastened to a bench by screws. Through the column of this fixed
jaw is formed a suitably shaped passage for the sliding bar B which is of considerable
height in proportion to its breadth.
The upper edge of this bar is provided with lateral flanges as shown in Figs. 2 or 4
and below the latter the bar is hollowed longitudinally to receive the screw spindle C
revolving loosely on the bar and engaging laterally with corresponding screw threads
in the sides of the jaw A. The spindle (passed loosely into the bar B through the
movable jaw F integral with the said bar carries a collar a abutting against the outer
face of the jaw F and is connected to the remote end of the bar B by a screw_G as
shown. The front part of the foot of the jaw A is elongated under the jaw F and
bar B to support the latter.

page_text: To form a more accurate bearing in the jaw A the material of the latter is cut away
or made hollow as at D D¹ towards the centre of its bearing guides so that the bar
is carried or guided only for a certain distance from the front and rear face of the
jaw. A similar recess or hollowing may be made also above the bar. In making
such vice to swivel, the jaw A is made without the lugs aforesaid and rests upon the
circular rail I fastened to the bench and is fixed by a central screw bolt in the usual
manner.
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. A vice having in combination a stationary jaw, a movable jaw, a bar integral
with said movable jaw and guides above and below in said stationary jaw and a screw
spindle in said bar engaging in threads in said stationary jaw so as to operate midway
between the guides of said bar.
2. A vice having a movable jaw and a bar integral therewith whereby said jaw is
guided in combination with a screw spindle journalled in said bar and operating
centrally with regard to the bearing flanges of said bar.
3. The combination of a jaw A hollowed at D D', a lengthened foot E a movable
jaw F, bar B having flanges as described screw spindle C with collar a and screw G
guided and operating substantially as and for the purpose set forth.
