Year: 1859

page_text: LETTERS PATENT to Robert Francis Drury and Ensor Drury, of the
Firm of Drury, Brothers, the Don Tool Works, Sheffield, in the County
of York, Machinists and Tool Makers, for the Invention of "IMPROVE-
MENTS IN VICES"
PROVISIONAL SPECIFICATION left by the said Robert Francis Drury
and Ensor Drury at the Office of the Commissioners of Patents, with
their Petition, on the 30th August 1859.
We, ROBERT FRANCIS DRURY and ENSOR DRURY, of the Firm of Drury,
Brothers, The Don Tool Works, Sheffield, in the County of York, Machinists
and Tool Makers, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN VICES," to be as follows:-
This Invention relates to what are known as parallel vices, and consists
essentially of a cheap and simple mode of combining the slides with the
moveable jaw, and also the combination of the body of the vice with the leg.
The moveable jaw, which slides to and fro over the edge of the bench, is
carried on a pair of lateral slides or bars, and is actuated by a screw spindle
working between them and passing through the tail of the jaw. The fixed
jaw, which is the front one, is supported by a leg resting on a stone block in
the floor, and like the rest of the parts is made of wrought iron.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Robert Francis Drury and Ensor Drury in the Great Seal
Patent Office on the 25th February 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ROBERT
O FRANCIS DRURY and ENSOR DRURY, of the Firm of Drury, Brothers, The Don

page_text: Tool Works, Sheffield, in the County of York, Machinists and Tool Makers,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of August, in the year. of our Lord
One thousand eight hundred and fifty-nine, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Robert Francis Drury and Ensor Drury, Her special license that we,
the said Robert Francis Drury and Ensor Drury, our executors, adminis-
trators, and assigns, or such others as we, the said Robert Francis Drury
and Ensor Drury, our executors, administrators, or assigns, should at any
time agree with, and no. others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IMPROVE-
MENTS IN VICES," upon the condition (amongst others) that we, the said
Robert Francis Drury and Ensor Drury, by an instrument in writing under
our hands and scals, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be performed;
and cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.-
:
NOW KNOW YE, that we, the said Robert Francis Drury and Ensor
Drury, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement, reference being had to the
accompanying Drawings, and, to the letters and figures marked thereon, that
is to say:
Our said Invention relates to what are known as parallel vices, and consists
essentially of a cheap and simple mode of combining the slides with the
moveable jaw, and also the combination of the body of the vice with the leg.
The moveable jaw, which slides to and fro over the bench, is carried on a pair
of lateral slides or bars, and is actuated by a screw spindle working between
them and passing through the tail of the jaw. The fixed jaw, which is the
front one, is supported in the standard vice by a leg resting on a stone block
in the floor, which leg in the bench vice is dispensed with. The whole of the
arts are made of wrought iron.
And in order that our said Invention may be fully understood, we shall now
proceed more particularly to describe the same, and for that purpose we shall
refer to the several Figures on the Sheet of Drawings hereunto annexed, the

page_text: same letters of reference indicating corresponding parts throughout all the
Figures.
Figure 1, represents a side elevation of our improved standard vice, and
Figure 2 is a corresponding plan of the same. A is the moveable vice jaw,
which is slid to and fro along the slide bars or rails B, by the screw spindle C.
These bars are forged at their front ends on to the sides of the front or
stationary jaw D, and are connected at their opposite ends to the surface of
the bench by a screw, as shewn at E. A cross piece b is also forged on to the
bars at this end for the purpose of connecting them together, and maintaining
them parallel to each other. The screw spindle C works loosely through a
hole in the stationary jaw D, passes through a nut or tapped hole made in the
tail a of the moveable jaw, and revolves freely in a hole in the cross piece b,
where it is retained by an external nut or collar F. The front stationary jaw
is forged in one piece with the leg or support G, which passes through a
clip H, for securing it to the edge of the work bench, and is supported at its
lower extremity upon a stone or wood block let into the floor of the workshop.
c, c, are plates secured to the front and back of the moveable jaw for the
purpose of protecting the screw from filings or dirt.
Figure 3 represents a side elevation, and Figure 4 a plan of a bench vice,
constructed according to our present Invention. This vice is of the same con-
struction as the standard vice, with the exception that the leg or support G is
dispensed with.
Having now described and particularly ascertained the nature of our said
Invention, and the manner in which the same is or may be used or carried into
effect, we would observe in conclusion, that what we consider to be novel
and original, and therefore claim as the Invention secured to us by the herein-
before in part recited Letters Patent is, the peculiar constructions of wrought-
iron vices, as herein-before described and illustrated by our Drawings.
In witness whereof, we, the said Robert Francis Drury and Ensor
Drury, have hereunto set our hands and seals, this Twenty-third
day of February, One thousand eight hundred and sixty.
