page_text: I, CHARLES NEIL of Cundy Street, Walkley, Sheffield, in the County of York,
Engineer and Tool Maker do hereby declare the nature of this invention to be as
follows:-
This invention relates to parallel bench vices of the general character of those
described in the Specification of my patent No. 2851 dated 12th July 1879 and in
which one jaw by means of a serrated wedge can be fixed on a serrated bar
whereon the other jaw can slide. Instead of making a screw at the end of the
serrated bar I make that end with a projection, by preference on the top side of
the bar, which projection is tapped to form a nut for the reception of the screw.
The serrated bar being passed through the slot in the movable jaw the projection
or nut enters into a recess made in the slot of the movable jaw to receive it, and a
screw works through the said nut with its end bearing against the internal face of
the recess in the movable jaw so that when the screw is turned to travel inwards
it pushes the jaw forward and thus the grip on the work is obtained when the
serrated bar is in gear with the wedge placed in the fast jaw. To bring the
movable jaw back with the screw when turning it to travel outwards the screw is
made with a collar having a groove into which fits a flange made at one end of a
cap (to protect the screw from dust &c.) the other end of which is fastened on the
movable jaw of vice.

I CHARLES NEIL, of Cundy Street, Walkley, Sheffield in the County of York,
Engineer and Tool Maker do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to improvements in parallel bench vices of the general
.character of those described in the specification of my patent No. 2851 dated
12th July 1879.
Figure 1 is a side view of a bench vice constructed according to this invention
and Figure 2 an end view of the fast jaw. Figure 3 is a right hand end view of
the sliding or screw jaw with section through the head of the screw. Figure 4 is a
vertical section through the movable jaw and Figure 5 a plan,
The bar A is serrated with one sided teeth on the underside as shown and can
be fixed in the fast jaw B by means of the wedge G which has corresponding one
sided teeth on its upper side and formed with double incline on its lower side.
The upper part of the slot through the fast jaw B is formed parallel with the bed
but the lower side of same where the bar A passes through is made slightly taper
or deeper towards the front as shown at B¹ to the depth of the serrations in the
wedge G whereby the serrations on the under side of the bar A fall into those in
the wedge sufficiently to draw the wedge up the inclines and when anything is
placed in the vice and screwed up the bar A becomes firmly secured in the jaw B.
At one end of the bar A and by preference on the top side I form or provide it
with a projection A' which is tapped to form a nut for the reception of the screw C,
or, as shown in dotted lines on the drawing, the nut A¹ may be dovetailed into the
bar A so that when worn or broken it may be replaced by a new one without
requiring a fresh bar A altogether as was necessary in the case of my former patent
where the bar was formed in one with a screw at one end. The bar A being
passed through the slot in the movable jaw E the projection or nut A¹ enters into
a recess made at the top in the slot in the movable jaw E to receive it and the
screw C works through the said nut B with its end bearing against the internal
face of the recess in the movable jaw E or by preference as shown against an
intermediate bearing plate e¹ so that when the screw O is turned to travel inwards
it pushes the jaw E forward and thus the grip on the work is obtained when the
serrated bar A is in gear with the wedge G placed in the fast jaw. To release the
work fixed in the vice I slacken back the screw C and the serrated bar A carrying
the movable jaw E can then be pushed closer to or drawn further away from the
fast jaw B with one hand of the workman, because by lifting the bar A. up against
the top of the slot in the jaw B the serrations of the bar A and the wedge G are
disengaged and the wedge G slides down the inclines by its own gravity (whereas
by the arrangement described in my aforesaid previous patent specification this
disengagement of the wedge had to be done by the workman's other hand
acting on a lever or a knob and spring provided for that purpose). To bring the
movable jaw E back with the screw A when turning it to travel outwards the

page_text: screw is made with a collar f having a groove f¹ into which fits a flange f* made
at one end of a saddle-shaped cap F, the other end of which is fixed to the movable
jaw E by two screws h h¹. The cap F also serves to keep the screw from dust and
to protect it from blows.
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. The improved form of slot for the bar A through the fast jaw B, that is to
say, making it tapering below towards the front whereby the serrations of the bar
and wedge can be easily disengaged substantially as set forth.
2. The improved form of serrated bar A, that is to say, forming or providing it
at one end with a nut, the screw for same being connected to the movable jaw E
substantially as set forth.
