Year: 1854

page_text: LETTERS PATENT to William Robinson, of the City of Manchester, in
the County of Lancaster, Screw Bolt Maker, and Robert Crighton, of
the same place, Engineer, for the Invention of "IMPROVEMENTS
MACHINERY OR APPARATUS FOR ROLLING METALS INTO SUITABLE SHAPES OF
FORMS."
Sealed the 8th January 1855, and dated the 8th July 1854.
PROVISIONAL SPECIFICATION left by the said William Robinson and
Robert Crighton at the Office of the Commissioners of Patents, with
their Petition, ou the 8th July 1854.
WC, WILLIAM ROBINSON, of the City of Manchester, in the County of
Lancaster, Screw Bolt Maker, and ROBERT CRIGHTON, of the same place,
Engineer, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR ROLLING METALS INTO SUITABLE SHAPES
OR FORMS to be as follows:-
These improvenients consist in making the rollers of such a form that the
iron or other metal in passing through them will be reduced at once to the

page_text: shape or form required, as, for instance, the shape or form of a hexagon nut
for screw bolts, which is the form shewn in the accompanying two Sheets of
Drawings, as proceeding from the machino ready forged, instead of being
forged or formed by hand, as hitherto done. By this improved machine, the
labour and expense of forming or forging nuts or similar articles will be much
No. 1
reduced, and the operation performed in a much more perfect manner.
Sheet of the accompanying Drawings shows an ond clevation of the rollers,
the periphery of which is fluted, or formed according to the figure or form of
the article required to be rolled; and No. 2 Sheet shews a front elevation
of the same, placed upon the shafts of the machine, which may contain any
number of the improved rollers for different sizes or figures, according to the
width or length of the machine.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Robinson and Robert Crighton in the Great Seal
Patent Office on the 8th January 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
ROBINSON, of the City of Manchester, in the County of Lancaster, Screw Bolt
Maker, and ROBERT CRIGHTON, of the same place, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Royal
Letters Patent, bearing date the Eighth day of July, in the year of our Lord
One thousand eight hundred and fifty-four, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said William Robinson and Robert Crighton, Her special licence that we, the
said William Robinson and Robert Crighton, our executors, administrators,
and assigns, or such other's as we, the said William Robinson and Robert
Crighton, our 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 "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR ROLLING METALS INTO SUITABLE SHAPES OR FORMS,"
upon the condition (amongst others) that we, the said William Robinson and
Robert Crighton, by an instrument in writing under our hands and seals,

page_text: or under the hand and scal of one of us, 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 Royal Letters Patent.
NOW KNOW YE, that we, the said William Robinson and Robert
Crighton, 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 (that is to say):-
Our Invention relates to machinery or apparatus for rolling metals to
any required shape or form, and is particularly applicable for forming the
nuts of screw bolts or similar articles, and which we accomplish by making
the rollers through which the metal passes of a peculiar shaped surfaces,
so that when the bar of metal has passed through them the nut or other
article intended to be made is formed to the required shape, instead of being.
forged or formed by hand, as hitherto done. The details of this Invention
will be clearly understood by reference to the accompanying Sheet of Drawings,
in which the rollers are shewn as formed to make a hexagon nut for screw
bolts; and the same letters of reference are used to represent the same parts
in all the Figures. Figs. 1 and 2 are end views of the improved form of the
rollers, the peripheries of which are fluted, or formed according to the figure or
form of the article required to be rolled. Fig. 3 is a front elevation of the
same, placed upon the shafts or mandrills of the machine, and which may
contain any number of the improved form of rollers for different sizes and
figures, according to the width or length of the machine.
A, A, are the shafts or mandrills of the machine, upon which the rollers B, B,
are made fast between the collars and flanges C and C, which form the groove
between which the iron passes in receiving the required form. The rollers
and flanges are shown to be separate, and keyed fast upon the shaft or man-
drill, and screwed fast together by means of the nuts D' and D.
Having thus fully described the nature and particulars of our said Invention,
we desire it to be distinctly understood that we do not confine ourselves to
the exact details herein set forth, as such may be varied or modified without
departing from the principle thereof; but we claim as of our Invention, and
which, to the best of our knowledge and belief, has not been hitherto used
within this realm, the use of rollers in rolling machines with their surfaces
or peripheries formed so as to give the object passing through them the form

page_text: or shape required, as hexagonal nuts, or similar articles, as such Invention
is herein described, and illustrated in the accompanying Sheet of Drawings.
In witness whereof, we, the said William Robinson and Robert Crighton,
have hereunto set our hands and seals, this Fifth day of January, One
thousand eight hundred and fifty-five.

ROBERT CRIGHTON. (L.S.)

named William Robinson and Robert
Crighton, in the presence of
