Patents, No. 1º, Welbeck Street, Cavendish Square, London, in the
County of Middlesex, Patent Agent, for the Invention of "AN IMPROVED
MODE OF MANUFACTURE OF WHEEL TIRES FOR RAILWAY CARRIAGES AND
ENGINES BY MEANS OF THE HEREIN DESCRIBED APPARATUS."-A com-
munication from abroad by Duplay, Vidal, Lachaise & Co., No. 10, Rue
Mogador, Paris, in the Empire of France.
Sealed the 30th December 1859, and dated the 6th July 1859.
PROVISIONAL SPECIFICATION left by the said Jozé Luis at the Office
of the Commissioners of Patents, with his Petition, on the 6th July
1859.
I, JozÉ LUIS, of the British and Foreign Office for Patents, No. 1º,
Welbeck Street, Cavendish Square, London, in the County of Middlesex,
Patent Agent, do hereby declare the nature of the said Invention for
AN IMPROVED MODE OF MANUFACTURE OF WHEEL TIRES FOR RAILWAY CARRIAGES
AND ENGINES BY MEANS OF THE HEREIN DESCRIBED APPARATUS," & that it has
been communicated to ine from abroad by Duplay, Vidal, Lachaise & Co.,
No. 10, Rue Mogador, Paris, in the Empire of France, to be as follows :—
1st. Rolling the bands.-The bands coming from the forge are hammered
thin at one end, and at the other are soldered to a rectangular band of iron to
form the interior of the tire, and to draw the steel on the part exposed to the

page_text: friction of the rails in rotation. The bands thus prepared are then rolled into
a hoop form by means of a rolling cylinder for that
purpose.
2nd. The soldering.-The rundle or metal hoop thus formed is then placed
in a reverberatory furnace and heated to the required heat, it is then brought
quickly to the stamper, which is arranged as follows:-A cast-iron matrice
bound round at the top by a strong iron hoop, this matrice receives a guide
which is moved vertically, a bolt is placed in a groove arranged at the bottom
of the matrice & serves to support this guide, keeping it in its position, the
rundle is then placed on the matrice and the hammer worked. In this
operation the rundle receives the percussion stroke vertically reproduced on
all the sides, 1st, of the guide, and 2nd, of the matrice, being strongly struck
by the hammer. The rundle or metal hoop takes its form, and the operation
is finished, its duration is about 3 minutes; the bolt above mentioned is then
withdrawn, a driving guide is then placed on the guide above mentioned, the
hammer acts upon it, the guide descends, and the rundle or metal hoop can at
once be removed without difficulty.
To proceed to a second operation the guide is raised by means of a lever,
the bolt is then placed and so on. This soldering so quickly done and yet so
perfect is performed on the whole of the tire without the least alteration of the
metals, except to their improvement.
Rolling. On removal from the matrice the rundle, if still warm enough, is
carried to the flatting or rolling mill, where it is finished in a few minutes to
the shape and size required. Should it not be sufficiently warm it must bo
reheated. The rolling mill which we use is moved by hydraulic pressure; as
soon as the rundle is placed in the rolling mill the cylinder, whatever be its
weight, descends instantaneously, and the pressure is at once communicated;
the other cylinders are then put in motion and the operation is completed.
Lastly. It must be observed that the power of tightening or loosening can
always be performed when required, only an ordinary amount of care being
necessary, and acting with great promptitude, security, & facility. For the
tires of iron and those of steel the bands are rectangular, but they are sub-
jected to the same hammering to taper the ends, the same rolling and other
operations as those in iron & steel.
By the system above described the work is better, considerably cheaper, &
done with greater rapidity, and the apparatus is at the same time simple and
casy to manage.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOZE
Luis, of the British & Foreign Office for Patents, No. 1º, Welbeck Street,
Cavendish Square, London, in the County of Middlesex, Patent Agent, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of July, in the year of our Lord One
thousand eight hundred and fifty-nine, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Jozé Luis, Her special licence that I, the said Jozé Luis,
my executors, administrators, and assigns, or such others as I, the said
Jozé Luis, my executors, administrators, and assigns, should at any time
agreo 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 "AN IMPROVED
MODE OF MANUFACTURE OF WHEEL TIRES FOR RAILWAY CARRIAGES AND ENGINES
BY MEANS OF THE HEREIN DESCRIBED APPARATUS," a communication from abroad
by Duplay, Vidal, Lachaise & Co., No. 10, Rue Mogador, Paris, in the
Empire of France, upon the condition (amongst others) that I, the said Jozó
Luis, my executors or administrators, by an instrument 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 Scal
Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said Jozé Luis, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, and accompanying Drawings, that is to say : —
The Invention consists in an improved construction of wheel tires, and in
the apparatus employed therefor. The tires are made of two bands or strips,
one of iron and the other of steel; the bands of iron are grooved or concave,
as represented A, a, Fig. 1, plate I., and are of the required size, length, and
shapo, to suit the dimensions of the tires of which they are to form a part;
the bands of steel are convex in form, and are made to suit the form of the

page_text: The steel
iron band, as represented 1, Fig. 1, and 6, the same in section.
band is only sufficient in size to complete the exterior of the tire; in order to
give it the necessary length a band of iron of the same form and size is welded
to it, M that when the two bands A, B, nre rolled together, the interior of the
metal hoop or tire is entirely of iron, and the outer circumference entirely of
steel; the bands thus prepared are wedge-shaped at each end; they are then
rolled into a ring forin as represented in section C' and in plan C, Fig. 2, P. 1,
by means of the rolling machine which is represented; Fig. 3, P. 1, a front
elevation, and Fig. 4, P. 1, a plan of the same. The shaft A is put in move-
ment by means of the cog work B, this shaft is furnished at one end with a
nut-vice or holdfast C, c', Fig. 4. The bands to be rolled are fixed in the
holdfast by means of a nut screw at the height of the wedge-shaped piece.
An hydraulic piston D bearing a roller E presses against the band, and
maintains it without pressing it against the holdfast; the bands being thus held
the shaft is put in motion by steam power, the bands slide along on the rollers
F, which serve to conduct and support it, and they are rolled into a ring form
around the head of the shaft. The rundle or ring thus made is removed as
follows: The piston D is made to descend, the nut screw fixing the holdfast is
unscrewed, and the holdfast is made to slide into a groove, so that it becomes
level with the rolling shaft, and pressure is then applied between the cavities
with which the shaft is furnished and the rundle. The welding of the ring or
rundle thus made is effected by means of the apparatus represented in section,
Fig. 5, P. 1, and in plan, Fig. 6, P. 1. Ou being removed from the furnace
to which it is subjected, the rundle is at once placed in the mould or matrix G,
a pile hammer is made to act on the hammer F, and the ring or rundle is
hermetically welded together by pressure on every part. The bolt J is with
drawn, and by means of the top fuller or driver E which is struck by the pile
hammer, the guide D is made to fall to the bottom of the mould, and the
rundle now perfectly welded may be removed. To commence a second opera-
tion the guide D is raised by means of levers K, and the bolt J is replaced.
The hoop or ring is then reheated, should it not be sufficiently warm, and it is
next subjected to the action of a rolling mill represented; Fig. 1, P. 2, front
elevation; Fig. 2, P. 2, side elevation. The laminating cylinders A, B, held in
their journals are put in movement by stean power; the journals of the lower
cylinder are fixed in their cages, but the journals of the upper cylinder B are
moveable in a vertical direction; a counterweight C serves in raising the
cylinder B by means of the shaft D and the crank E, which are fixed to
the journals of the said cylinder B. The counterweight thus balances the
cylinder.

page_text: The piston of an hydraulic press fixed to the frame of the rolling mill
presses against the journals of the upper cylinder, and thus compresses the
tire which is placed at F between the two cylinders. The rollers G serve to
guide and keep the tire in its place during the operation; they are regulated
by an adjusting screw H according to the different diameters which the tires
may have. On the tire having attained the necessary diameter the hydraulic
pressure is discontinued; by means of the counterweight the upper cylinder is
raised and the tire can be removed finished. At any time during the operation
the pressure can be increased or diminished. In the tires of iron or of steel
the bands are rectangular and wedge-shaped at their extremities, and are sub-
jected to the same operations as those of steel and iron.
Having thus described my Invention, and the means by which the same is
or may be carried out, I wish it to be distinctly understood that I do not
confine myself to the precise details of construction, reserving the right of
modifying the same; what I claim is,―
1st, construction of the tires of wheels of railway carriages, engines, and
tenders, of an iron and steel band, as above described and shown in the
annexed Drawings, Figs. 1 & 2, Plate 1,
2nd, the arrangement of apparatus for rolling the bands of steel and iron
into a circular form, as above described and shown in the accompanying
Drawings, Figs. 3 & 4, P. 1.
3d, the arrangement of apparatus for welding the iron and steel together,
as above described and shown in the annexed Drawings, Figs. 5 & 6, P. 1.
4th, the arrangement of apparatus for rolling and finishing the tires,
as above described and represented in the annexed Drawings, Figs. 1 & 2,
P. 2.
In witness whereof, I, the said Jozé Luis, have hereunto set my hand
and seal, this 2nd day of January, in the year of our Lord One
thousand eight hundred and sixty.
JOZÉ LUIS. (L.8.)
