Year: 1860

page_text: LETTERS PATENT to Alfred Buckingham Ibbotson, of Sheffield, in the
County of York, Steel and File Manufacturer, for the Invention of "Im-
PROVEMENTS IN VICES, PART OF WHICH IMPROVEMENTS IS APPLICABLE TO SCREW
WRENCHES, SPANNERS, TURNING LATHES, AND OTHER TOOLS AND MACHINES."
-A communication from abroad by Hiram Powers, of Florence.
Sealed the 13th November 1860, and dated the 17th May 1860.
PROVISIONAL SPECIFICATION left by the said Alfred Buckingham
Ibbotson at the Office of the Commissioners of Patents, with his
Petition, on the 17th May 1860.
I, ALFRED BUCKINGHAM IBBOTSON, of Sheffield, in the County of York, Steel
and File Manufacturer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN VICES, PART OF HICH IMPROVEMENTS IS APPLICABLE TO
SCREW WRENCHES, SPANNERS, TURNING LATHES, AND OTHER TOOLS AND MACHINES,"
(communicated to me from abroad by Hiram Powers, of Florence,) to be as
follows:-
This Invention consists, first, in making the front jaw of the vice a fixture
to the bench, and the back jaw the traveller. A barrel or tube is forged solid
to the front jaw and turned parallel on the outer surface, and bored parallel on
the inner surface. The back jaw is bored out and well fitted over the outer
surface of the tube. On the under side of the tube a slot or groove is made,

page_text: to admit the nut or box which forms part of the travelling or sliding jaw.
This nut or box also serves as a guide or conductor for the travelling jaw,
thereby adding much to its strength, firmness, and neatness. A screw passes
through the barrel or tube, and the washers at each end are recessed into the
solid of the barrel, so that the whole of the working parts are quite protected
from any filings or grit.
The Invention consists, second, in the mode of fixing the vice to the bench.
A bracket, through which a vertical hole is bored, is screwed to the bench, into
this hole the shank of the vice is dropped, and by this means the vice can be
fixed at any angle with the bench, and can be adjusted in an instant by a
screw or otherwise. The screw working through a barrel or tube of a similar
construction to that before described, is equally applicable to screw wrenches,
spanners, turning lathes, and other tools and machines.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Alfred Buckingham Ibbotson in the Great Seal Patent Office
on the 17th November 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
BUCKINGHAM IBBOTSON, of Sheffield, in the County of York, Steel and File
Manufacturer, send grecting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of May, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
said Alfred Buckingham Ibbotson, Her special licence that I, the said Alfred
Buckingham Ibbotson, my executors, administrators, and assigns, or such
others as I, the said Alfred Buckingham Ibbotson, my executors, adminis-
trators, and assigns, should at any time agree with, and no others, from
time to time and at all times thereafter 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 "IMPROVEMENTS IN VICES, PART OF WHICH IMPROVE-
MENTS IS APPLICABLE TO SCREW WRENCHES, SPANNERS, TURNING LATHES, AND OTHER
TOOLS AND MACHINES," (communicated to me from abroad by Hiram Powers,
of Florence,) upon the condition (amongst others) that I, the said Alfred
Buckingham Ibbotson, my executors or administrators, by an instrument

page_text: in writing under my, or their, or one of their hands and seals, 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 im-
mediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Alfred Buckingham Ibbotson, 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 thereof, reference being had to the Drawings hereunto annexed,
that is to say:-
On the under
This Invention consists, first, in making the front jaw of the vice a fixture to
the bench, and the back jaw the traveller, or vice versa, in manner as bereafter
stated. A barrel or tube is forged solid to the front jaw, and turned parallel
on the outer surface, and bored parallel on the inner surface. The back jaw
is bored out and well fitted over the outer surface of the tube.
side of the tube a slot or groove is made, to admit the nut or box which forms
part of the travelling or sliding jaw. This nut or box also serves as a guide
or conductor for the travelling jaw, thereby adding much to its strength,
firmness, and neatness. A screw passes through the barrel or tube, and the
washers at each end are recessed into tho solid of the barrel, so that the whole
of the working parts are quite protected from any filings or grit.
The Invention consists, second, in the mode of fixing the vice to the bench.
A bracket, through which a vertical hole is bored, is screwed to the bench;
into this hole the shank of the vice is dropped, and by this means the vice can
be fixed at any angle with the bench, and can be readily adjusted by a screw
or otherwise. The screw working through a barrel or tube of a similar con-
struction to that before described, is equally applicable to screw wrenches,
spanners, turning lathes, and other tools and machines.
a is the front jaw of
Figure 1 of the accompanying Drawings shews in side elevation, Figure 2
in sectional elevation, Figure 3 in end elevation, and Figure 4 in plan, a
vice in which both parts of this Invention are embodied.
the vice forged or cast in a piece with the barrel b; c is the back jaw fitting
the barrel b; d is a screw passing through the barrel 6 and through the nut
or box e, which is formed in a piece with the back jaw c, as seen in the face
view of the travelling jaw, Figure 5. A slot is made along the under part
of the barrel b; f is the handle for screwing up the vice. When the handle
is turned, the back jaw c is caused to travel along the barrel b, by means of
the nut c, through which the screw d passes; g, g', is a bracket for attaching

the bracket has a vertical hole bored in it, into which the shank % of the front
jaw a is dropped. The lower part of the shank is screw-threaded, and carries
a tightening nut i, which when the vice is placed in any desired position is
screwed up against the under part of the flange 9, as shewn in Figures 1 and
2, to retain it. Figure 6 is a side elevation, and Figure 7 a plan of a vico
made in a similar manner to that just described, but in which the mode of
securing it to a bench is different. The bed is screwed or otherwise
secured to a bench by screws passing through the flanges 1, 1; m is a lug or
projection abutting against the bench; n is a leg screwed into the bed k', and
intended to rest on the ground, but in the Drawing is shown broken. Figure 8
shews in side elevation, and Figure 9 in top view a shifting spanner fitted with
a scrow working through a barrel or tube, similar in construction to that
before described; a, b, are the jaws of the spanner; the jaw b is formed with
a nut or box travelling on the screw c, through the slot, shown clearly in Figure
9, in a similar manner to the jaw in the vicc. d is the knob at the end of the
screw for turning it and causing the jaw to move along the barrel. This
Invention is also applicable to swivel bench vices and hand vices in general.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim,-
First the employment of a screw working through a slotted barrel or tube
for vices, shifting spanners, lathes, and other tools and machines, as herein-
before described.
And second, the mode of fixing vices to benches in order that they may be
adjusted and retained in any desired position, in manner herein-before
described, and illustrated in the accompanying Drawings.
In witness whereof, I, the said Alfred Buckingham Ibbotson, have
hereunto set my hand and seal, this Fifteenth day of November,
One thousand eight hundred and sixty.
