IMPROVEMENTS IN THE MANUFACTURE OF TUBES MORE ESPECIALLY APPLICABLE TO THE BARRELS OF FIRE-ARMS AND ORDNANCE
Year: 1862

page_text: LETTERS PATENT to William. Rose, of Hales Owen, in the County of
Worcester, Manufacturer, for the Invention of "IMPROVEMENTS IN THE
MANUFACTURE OF TUBES MORE ESPECIALLY APPLICABLE TO THE BARRELS OF
FIRE-ARMS AND ORDNANCE."
Scaled the 17th October 1862, and dated the 19th April 1862.
PROVISIONAL SPECIFICATION left by the said William Rose at the Office
of the Commissioners of Patents, with his Petition, on the 19th April'
1862.
I, WILLIAM ROSE, of Hales Owen, in the County of Worcester, Manu-
facturer, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN THE MANUFACTURE OF TUBES MORE ESPECIALLY APPLICABLE TO THE
BARRELS OF FIRE-ARMS AND ORDNANCE," to be as follows:-
I take a strip, or what is termed in the trade a skelp, of iron or steel, and pass
it through rolls, by which it is turned up into a tube, or nearly approaching a
tube. I then cut this tube into lengths suitable for my purpose, which for
small arms would be about a foot each. Upon these short tubes I twist bands.
or ribbons of iron or steel, or both combined, into a rough coil, and, heating
the whole, I take it upon a mandril to a train of ordinary gun rolls, passing.;

page_text: it through the rolls once, twice, or three times as may be necessary. The
barrel is drawn out, and each coil of the twist securely welded upon the inside
tube, and also upon the adjoining coil.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Rose in the Great Seal Patent Office on the 18th
October 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
ROSE, of Hales Owen, in the County of Worcester, send greeting."
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of April, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Rose, Her special license, that I, the said William Rose, my
executors, administrators; and assigns, or such others as I, the said William
Rose, 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 "IMPROVEMENTS IN THE
MANUFACTURE OF TUBES MORE ESPECIALLY APPLICABLE TO THE BARRELS OF FIRE-
ARMS AND ORDNANCE," upon the condition (amongst others) that I, the said
William Rose, by an instrument in writing under my hand and seal, 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Rose, 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 state-
.nient (that is to say) :-
In carrying out my Invention with reference to the making of barrels of
fire-arms and ordnance, I take a strip, band, or skelp of iron or steel, or a
mixture of both, and pass it through grooves of the requisite section in a train
of rolls, or through dies on a draw bench, by which operation the metal is
turned up into a form nearly approaching a complete tube, or it may be com-

page_text: pletely formed into a tube, and securely welded by the rolling process, or in
the dies, if necessary. I then cut this tube or partial tube into lengths
suitable for the purpose for which the barrel may be ultimately intended,
which for a small arm, such as a rifle, would be about one foot each length.
Upon each of these short tubes I proceed to twist a band or bands, strips or
ribbands of iron or steel, or both combined, forming such bands into a rough
coil upon the inner lining tube. I then heat the whole mass, and take it from
the furnace upon a stop mandril, and jump it, if necessary, to close the coil.
I then take it at a welding heat upon an ordinary roller mandril to a train of
ordinary gun rolls, passing it through the grooves in such rolls once, twice, or
three times as may be requisite; the use of the mandril and the rolls ensuring
internal as well as external pressure, by which process the tube is drawn out,
and each coil of the twist is securely welded upon the inner lining tube, and
also edge to edge upon its adjoining coil, and in its last passage through the
rolls employing common barrel rollers, tapering mandrils, the necessary
taper required in a small arm barrel or piece of ordnance is given to the tube.
Should one band or coil upon the inner lining tube afford insufficient thick-
ness for the barrel, I coil back upon the former more bands until a sufficient
thickness of metal has been ensured. This operation is, of course, performed
before heating or welding the mass together: od
「う
In making ordnance and heavy arms I follow the same process, but with
more material, and suitable mechanical appliances for dealing with heavier
weights. After having coiled the strip or bands upon the inner or lining tube,
I heat the mass, and, if necessary, remove it upon a stop mandril to what is
known in the trade as a "jumping machine," in which under heavy blows from a
forge or steam hammer, or other suitable apparatus the coil is closed up edge-
ways. I then re-heat it, and take it upon a mandril to the rolls, which for
this purpose require to be of a very strong description. Passing it through
the grooves of these rolls the coil or coils are welded firmly on the tube by
the internal and external pressure.
In the manufacture of tubes other than those employed for fire-arms or
ordnance, I adopt the same processes already described, omitting the taper
rolling unless taper tubes are required. Tubes may also be made by this
process of other metals than iron or steel, and for other purposes than the
barrels of fire-arms or ordnance, provided the metal be capable of being welded
or united by heat.
Having thus described the nature of my said Invention, and in what manner
the same is to be carried into effect, I make no claim to the employment of

page_text: the machinery or apparatus herein described, but that which I do claim as
my Invention is, the improvements in the manufacture of tubes more espe-
cially applicable to the barrels of fire-arms and ordnance, by combining the
twisted skelp or coil with the inner or lining tube, substantially as herein
more fully set forth and specified. *
In witness whereof, I, the said William Rose, have hereunto set my
hand and seal, this Ninth day of October, in the year of our Lord
One thousand eight hundred and sixty-two.
WILLIAM (L.s.) ROSE.
