IMPROVEMENTS IN THE MANUFACTURE OF RAILWAY AND OTHER AXLES, SHAFTS, AND BARS
Year: 1844

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
HILL, of Harts Hill, Dudley, Worcester, Ironmaster, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Fourteenth day of May, in the Seventh year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said Edward
Hill, Her especial licence, full power, sole privilege and authority, that I, the
said Edward Hill, my exors, admors, and assigns, or such others as I, the said
Edward Hill, my exors, admors, or assigns, should at any time agree with,
and no others, from time to time and at all times during the term of years
therein expressed, should and lawfully might make, use, exercise, and vend,
within England, Wales, and the Town of Berwick-upon-Tweed, my Invention
of "IMPROVEMENTS IN THE MANUFACTURE OF RAILWAY AND OTHER AXLES, SHAFTS,
AND BARS;" in which said Letters Patent is contained a proviso, that I, the
said Edward Hill, shall cause a particular description of the nature of my said
Invention, and in what manner the same is to be performed, to be inrolled in
Her said Majesty's High Court of Chancery within six calendar months next
and immediately after the date of the said in part recited Letters Patent, as
in and by the same, reference being thereunto had, will more fully and at
large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Edward Hill, do hereby declare that the nature of my Invention, and the
manner in which the same is to be performed, are fully described and ascer-
tained in and by the following statement thereof, reference being had to the
Drawing hereunto annexed, and to the figures and letters marked thereon
(that is to say)-
:-
My Invention consists in applying bars of iron rolled into such form that
the section thereof is a cross. And in order that my Invention may be fully
understood and readily carried into effect, I will proceed to describe the means
pursued by me.
DESCRIPTION OF THE DRAWING.
Figure 1 represents the section of iron bar which I employ in manu-
facturing railway and other axles, and shafts and bars for other purposes; and
the spaces a, a, are to be filled up with other bars b, b, as is shewn at Figure 2,
if for a cylindrical axle, shaft, or bar, and the whole welded together; and if the
bar or shaft is to be square, then the section of the filling pieces should be
square as is shewn at Figure 8 at c, c; or other sections of bars, axles, and
shafts may be produced, having the central bar, the section of which is a cross,
according to the figure of the grooves in the rollers used in welding such bars;
and it is not necessary that the angular spaces a, a, should each be filled with
only one bar or piece, as those spaces may be filled with several pieces and
then welded into one bar by means of rollers, tilt hammers, or other means, as
is well understood when welding several bars into one; and although I generally
employ only iron for the centre bar and for the filling pieces, yet, if desired,
steel may be used in combination with iron either in forming the cross or
centre bar or for the filling pieces.
I would remark that it is not necessary in all cases that the bars 6 should
fill the angles a, a, as they may be formed suitable for leaving the parts near
the centre hollow. In some cases, where the strength of the central bar or
cross will be strong enough for the desired axle or shaft, then I only fill the
angular spaces a, a, of the cross or central bar with filling pieces at those parts
where the axle or shaft is to turn in bearings or otherwise requires to be filled
up; the other part of the shaft or axle being simply composed of the central
bar; or the cross or central bar may be made strong enough in the first instance
to admit of the bearings being turned without applying any filling pieces. It
will only be necessary further to state, that bars of a cylindrical or other form
being thus manufactured are to be forged and formed as heretofore, accord-
ing to the purposes to which they are to be applied.

page_text: Having thus described the nature of my Invention, and the best means
I am acquainted with for performing the same, I would remark that I make
no claim to the rolling of bars of angle iron, each offering in its transverse
section the form of a cross, that having been before done for other purposes.
But what I claim is, the mode of manufacturing railway and other axles, shafts,
and bars, by applying as the central part thereof bars each offering the figure
of a cross in its transverse section, as above described.
In witness whereof, I, the said Edward Hill, have hereunto set my hand
and seal, this Ninth day of November, in the year of our Lord One
thousand eight hundred and fourty-four.
EDWARD (L.8.) HILL.
Signed, sealed, and delivered by the within-
named Edward Hill, in the presence of
W FELLOWES, Jun', Solic', Dudley.
AND BE IT REMEMBERED, that on the Ninth day of November, in the
year of our Lord 1844, the aforesaid Edward Hill came before our said Lady
the Queen in Her Chancery, and acknowledged the Specification aforesaid,
and all and every thing therein contained and specified, in form above written.
And also the the Specification aforesaid was stamped according to the tenor
of the Statute made for that purpose.
