PROVISIONAL SPECIFICATION left by the said Jozé Luis at the Office of
the Commissioners of Patents, with his Petition, on the 17th April
1858.
I, JOZE LUIS, of No. 1, Welbeck St. (Cavendish Square), in the County
of Midlesex, do hereby declare the nature of the said Invention for "A NEW
SYSTEM OF WINDOW FRAMES FOR RAILWAY CARRIAGES," (a communication,) to be
as follows:-
The modifications which we introduce in the manufacture of window frames
for railway carriages, tenders, and luggage vans consists in the use of double
iron corner plates, whose dimension and shape varies according to the shafts
and extreme traverses.
The shafts are fastened together, (1st), at the extremities by the extreme
traverses, on which they join by means of iron squares; (2dly), at different
parts of their length by intermediate traverses made of iron, which also join on
the shafts by iron squares.
The perfect rigidity of the window frames is completed by two crossed irons
fixed above all the intermediate traverses by iron pins or rivets, and joined on

page_text: the extreme traverses by their extremities, screwed by means of nuts, these
pieces being arched prevent the flexion which the shafts might otherwise make
under very heavy loads.
The shafts are strengthened at the points where the suspension springs end
by bars of cast iron.
ADVANTAGES OF THE ABOVE.
Window frames for railway carriages have been attempted and those for
tenders are always made of iron, but the shafts being made either of beams of
sheet iron or of sheet iron armed with corner plates. In each case the
workmanship of the frames is very expensive, and their weight very con-
siderable.
The use of irons with double corner plates, which we employ in our frames
for the shafts and extreme traverses, offers the great advantage of presenting
in the interior of the frame a perfectly level surface, against which can be
adapted as easily as on wood all accessory irons, and amongst others the guard
plates, the plates, and counter plates of traction hooks, screw, rings, and safety
chains cross quartered, &c., &c., and which, moreover, permits the use (in their
usual state) of the iron parts belonging to carriage window frames in wood.
The weight of our iron frames is nearly the same as those made of wood,
and they do not cost more; moreover, they last a great deal longer.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said José Luis in the Great Seal Patent Office on the 6th
October 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSÉ
LUIS, of 1, Welbeck Street, Cavendish Sqr, in the County of Middlesex,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of April, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-first year of
Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said José Luis, Her special licence that I, the said José Luis,
my executors, administrators, and assigns, or such others as I, the said José
Luis, 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

page_text: 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 "A NEW SYSTEM OF WINDOW FRAMES FOR
RAILWAY CARRIAGES," a communication, upon the condition (amongst others)
that I, the said José 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
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 José Luis, 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 statement,
that is to say:-
The modifications which we introduce in the manufacture of framework for
railway carriages, tenders, luggage vans consist in the use of double corner
iron plates, whose dimensions and shape varies according to the shafts and
cross beams.
The shafts are fastened together, 1st, at the ends by the cross beams, on
which they are held by means of iron squares; 2nd, at different parts of their
length by intermediate iron beams with double elbow joints, which meet on
the shaft, held by iron squares.
The perfect rigidity of the framework is completed by two elbow-jointed
cross bars of iron fixed below all the intermediate cross beams by bolts or
rivets, and which are kept on the end cross beams by means of screws at their
ends; these pieces are bent, thus preventing a flexion that the shafts might
otherwise have under heavy loads.
The shafts are strengthened at the parts where the suspension springs end
by bars of cast iron.
Frames for railway carriages have been attempted and those for tenders are
always made of sheet iron beams or sheet iron with angle irons. In both
cases the workmanship is expensive and the weight very considerable.
By our method the following advantages are gained :-The double corner
iron plates which we use in our frames for the shafts and end cross beams
offer the great advantage of presenting in the interior of the frame a perfectly
level surface, to which can be adapted as easily as on wood all the ironwork
necessary, among which may be mentioned the guard plates, the plates and
counter plates of traction books, ring screws of safety chains, &c., &c., and

page_text: also permits of all the iron fastenings, &c. being used, such are are now used
on those having a wooden framework.
The weight of our iron framework is about the same as that of wood, its
cost is not dearer, it is much more durable, and its resistance is much greater.
In witness whereof, I, that said Jozé Luis, have hereunto set my hand
and seal, this Sixth day of October, in the year of our Lord One
thousand eight hundred and fifty-eight.
JOZE LUIS. (L.S.)
