PROVISIONAL SPECIFICATION.
An Improved Bench Vice.
A communication from abroad by AUGUSTE SOUTY, of 2, Passage du Chemin
Vert, Paris, in the Republic of France, Manufacturer.
I, GEORGE CLEMENT DOWNING, of 8, Quality Court, London, W.C., Patent
Agent, do hereby declare the nature of my said invention to be as follows :-
The object of this invention is to effect improvements in fitting benches, for
carpenters and others, with vices for holding materials in position, while being
manipulated.
The invention consists of a long screw actuating a travelling nut, such nut
carrying a travelling jaw, projecting through a slot in the bench a corresponding
stationary jaw being fitted at one end of the bench. The materials to be operated
upon are placed between the jaws, and the screw is used to force the travelling jaw
against the material, so as to hold the same with sufficient firmness between the two
jaws.
I form in the substance of the bench board a long groove extending from the
underside to nearly the upper surface of the board, leaving a thickness of about
from of an inch to an inch of wood above the slot or recess. Another (narrower)
slot is cut through from the upper surface, opening into the first named slot. In
the first named slot I fit the screw, to which is fitted the travelling nut, which is
formed rectangular so as to travel in the slot without revolving. One end of the
long screw reaches to the end of the bench, and is formed with a shoulder to receive
a stationary plain nut or washer, and also to receive a fixed or movable crank or
handle for operating the same.
The travelling nut is recessed or grooved so as to receive the travelling jaw or
post which is guided between the parallel sides of the upper slot.
In case the bench board happens to be too thin to recess the screw, I form such
recess by means of additions under the board, and enclose the same in an equivalent
manner to that above described.
Instead of the screw above mentioned a countersunk rack may be fitted, with a
toothed pinion and pawl, arranged under the bench board.

I, GEORGE CLEMENT DOWNING, of 8, Quality Court, London, W.C., Patent
Agent, do hereby declare the nature of my said invention, and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
The object of this invention is to effect improvements in fitting benches, for
carpenters and others, with vices for holding materials in position, while being
manipulated.
And in order that the invention may be more particularly described and ascer-
cained, reference is made to the accompanying drawings in which similar letters of
reference indicate corresponding parts.

Fig. 3 is a plan and
Fig. 4 is an enlarged view of the collar or thrust plate O.
The invention consists of a long screw F actuating a travelling nut E such nut
carrying a travelling jaw B projecting through a slot in the bench: a corresponding
stationary jaw B₁ being fitted at one end of the bench. The materials to be
operated upon are placed between the jaws, and the screw is used to force the
travelling jaw against the material, so as to hold the same with sufficient firmness
between the two jaws.
I form in the substance of the bench board a long groove extending from the
underside to nearly the upper surface of the board as shown in dotted lines in Fig. 1
leaving a thickness of about from of an inch to an inch of wood above the slot or
recess. Another (narrower) slot is cut through from the upper surface, opening
into the first named slot. In the first named slot I fit the screw F to which is fitted
the travelling nut E which is formed rectangular so as to travel in the slot without
revolving. One end of the long screw reaches to the end of the bench, and is formed
with a shoulder to receive a stationary plain nut or washer, and also to receive a
fixed or movable crank or handle for operating the same.
The other end of the screw F has a bearing at G.
At the handle end of the screw a collar or thrust plate O is placed, the object of
which is to retain the screw in position and to resist the thrust of the same.
This
collar or thrust plate O is kept in position by means of a cover or plate P which
also prevents the access of dust to the working parts of the apparatus.
The travelling nut is recessed or grooved so as to receive the travelling jaw or
post which is guided between the parallel sides of the upper slot.
In case the bench board happens to be too thin to recess the screw, I form such
recess by means of additions under the board, and enclose the same in an equivalent
manner to that above described.
Instead of the screw above mentioned a countersunk rack may be fitted, with a
toothed pinion and pawl, arranged under the bench board.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
1. In a bench vice of the class described the use and application of the screw F,
travelling nut E with travelling jaw B and collar or thrust plate O, actuated by a
crank handle substantially as described and illustrated by the drawings.
2. The general combination and arrangement of parts together forming the
improved bench vice substantially as described and illustrated by the drawings.
