IMPROVEMENTS IN ROLLING MANIACTURE OF BOLTS AND Prog
Year: 1858

page_text: LETTERS PATENT to Joseph Dodge Weston, of Stour Valley Iron Works,
West Bromwich, in the County of Stafford, and of the City and County
of Bristol, Manufacturer, for the Invention of "IMPROVEMENTS IN ROLLING
MANIACTURE OF BOLTS AND Prog"
IRON FAR
PROVISIONAL SPECIFICATION left by the said Joseph Dodge Weston
at the Office of the Commissioners of Patents, with his Petition, op
the 7th July 1858.
I, JOSEPH DODGE WESTON, of Stour Valley Iron Works, West Bromwich,
in the County of Stafford, and of the City and County of Bristol, Manu-
facturer, do hereby declare the. nature of the Invention for "IMPROVEMENTS IN
ROLLING IRON FOR THE MANUFACTURE OF BOLTS AND PINS," to be as follows:-
To make bolts or pins with projecting angles or any other elevations on the
stems under the heads, I first roll the iron in the usual manner into an
elliptical or other section; I then pass it through a pair of rolls, in which the
shape of the projecting angle or elevation required on the neck of the finished
bolt or pin, or which may facilitate the formation of any notch, angle, or other
elevations on the neck of the bolt, is indented at regular distances. The bars
being thus rolled, I cut them up, by the usual modes, in lengths for the for-
mation of bolts or pins. The indentation upon the rolls may be cut or engraved,
so as to shape the iron sufficiently long in the projecting part to admit of its

page_text: being divided to form the neck, and allow sufficient iron for making the heads
of two bolts or pins, or it may be of the length required for one bolt or pin
only.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Dodge Weston in the. Great Seal Patent Office
on the 7th January 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
DODGE WESTON, of Stour Valley Iron Works, West Bromwich, in the County
of Stafford, and of the City and County of Bristol, Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of July, in the year of our Lord One
thousand eight hundred and fifty-eight, in the twenty-second year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Joseph Dodge Weston, Her special licence that I, the said Joseph Dodge
Weston, my executors, administrators, and assigns, or such others as I, the
said Joseph Dodge Weston, my executors, administrators, 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 "IM-
PROVEMENTS IN ROLLING IRON FOR THE MANUFACTURE OF BOLTS AND PINS," upon
the condition (amongst others) that I, the said Joseph Dodge Weston, my
executors or administrators, by an instrument in writing under my, or their,
or one of their hands and seals, sliould 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 I, the said Joseph Dodge Weston, do hereby
declare the nature of the 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, that is to say :-
To make bolts or pins with projecting angles, or any other elevations on
the stems under the heads, I first roll the iron in the usual manner into an
elliptical or other section. I then pass it through a pair of rolls in which the

page_text: shape of the projecting angle or elevation required on the neck of the finished
bolt or pin, or which may facilitate the formation of any notch, angle, or other
elevations on the neck of the bolt is indented at regular distances.
The bars being thus rolled I cut them up, by the usual modes, in lengths for
the formation of bolts or pins. The indentation upon the rolls may be cut or
engraved, so as to shape the iron sufficiently long in the projecting part to
admit of its being divided to form the neck, and allow sufficient iron for
making the heads of two bolts or pins, or it may be of the length required for
one bolt or pin only.
Having thus stated the nature of my said Invention, I will proceed more.
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figure 1 shews different views of the form of bolt which I prefer to make,
but other forms of bolts and pins may be made in a similar manner. In the
example shewn at Figure 1, there is simply an angular projection on one side
of the stem and just below the head, but the projection may be different in
shape or form to that shewn, and more than one projection may be produced
on the stem just below the head.
The peculiarity of the Invention consists in rolling rods or bars of iron with
the requisite projection or projections thereon, so that when cut into proper
lengths for the bolts, such projection or projections may form, or be formed
into the shape required under the head of each bolt or pin. Figure 2 shews
a bar or rod of iron of a cylindrical section, except at the places where the
projections are formed thereon. The rod or bar, Figure 2, is rolled suitably
to be divided at the dotted lines a, a, and at b, b. The ends a, a, are then to
be upset by a suitable die, or heading tool (according to the shape of head
desired) whilst the stem and part of the projection is held within a suitable
holding die. Figure 3 shews another bar or rod of iron rolled into a proper
form to be divided at the points d, d; the projections .c, c, in this bar being
each only suitable for producing one head, and one projection below the head
to one bolt, whereas the projections on the bar or rod, Figure 2,. are each
suitable for making the heads and projections of two bolts. Figure 4 shews
another bar or rod of iron rolled into a proper form to be divided at the points
F, F, the projections E, E, in this bar being each suitable for forming one
projection, under the head of one bolt, such head being formed by the upsetting
or throwing down of the portion of iron between the points F, F, and E. In
like manner other cylindrical rods or bars may be similarly rolled, with pro-
jections of different shapes or forms to those shewn, and when desired two or

page_text: more projections may be rolled, so that when the bars or rods have been cut,.
and the heads formed on the separate pieces, there will be to each bolt or pin
a suitable head, and below it a projection or projections of the form or shape
desired.
In witness whereof, I, the said Joseph Dodge Weston, have hereunto set.
my hand and seal, this Third day of January, in the year of our
Lord One thousand eight hundred and fifty-nine.
