page_text: I NEWTON PILKINGTON DAVISON of 5 Kentish Town Road St Pancras in the
County of Middlesex Writer, 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 :—
The object of my invention is to construct improved Railways and Rolling Stock,
for the attainment of higher speeds than hitherto has been found practicable.
In carrying out my invention I construct the Railway of a box form, and,
preferably, of light open ironwork.
Each line is provided with four rails, two under the Carriages as usual, and two
overhead; the Carriages being fitted with Wheels to correspond.
And in order that my said invention may be particularly described and ascer-
tained, reference is hereby made to the accompanying drawings, which illustrate
in a general manner the character of my invention.
Fig. 1. is an elevation, shewing one form of the Cars to be used in connection
with my improved Railway.
Fig. 2. is a section, shewing my improved tubular form of railway, and cars inside
the same.
Fig. 3. is a perspective view, shewing the Railway, elevated on suitable ironwork
supports, for travelling through or over Cities and Towns, and wherever else such
construction is suitable.
Fig. 4. is a perspective view, shewing my improved Railway adapted to low
levels, cuttings, and underground travelling.
Fig. 5 is a perspective view of a Station, with a train at rest at a Platform.
In the construction of the railway Cars I make use of the lightest materials,
consistent with sufficient strength; light steel frames, fitted with thin wooden
panels, being applicable for the purpose; but other suitable materials may be used.
The form of the Cars may be Square with the upper corners taken off diagonally,
as shewn in the drawings, and of proportionate length; the Cars are supported on
wheels and springs, in the usual manner, and are propelled by Engines with large
driving wheels (formed in one with the Cars, or separate therefrom as preferred)
and worked by steam, compressed air, electricity or other motive power.
The Cars may also be driven singly, and made with tapering ends, with aerial
screws, at either or both ends, to increase the speed (as shewn by dotted lines in
Fig. 1) if found advantageous.

page_text: To the upper diagonal corners of the Carriages I fit small wheels, which fit on
to light rails, fitted to the diagonal corners or angles of the tubular or other
railway, with adjustable springs, forming a protection at the top of the Cars, and
confining them easily and securely on the rails.
In applying my invention to travelling over Cities and Towns, the Railway is
(preferably) raised above the house tops, upon. light iron work, or other suitable
supports, as shewn in Fig. 3; and on the lower levels the same system may be
carried out, the underground tunnels being also fitted with the upper protecting
rails, the gradients and levels of the course being formed as circumstances require,
and as illustrated in Figs. 3 and 4 of the drawings.
In Fig. 1 one of my proposed forms of Oars is shewn. A is a portion of the
interior, fitted with a light description of seats, B. B are the before mentioned
grooved wheels, to travel on or against the upper rails, constituting the upper
protection to the Car.
The dotted lines C. C. shew tapering ends, fitted with aërial screws, which may
be driven by any convenient gearing in connection with the motive power used.
The dotted lines D ropresont an extra sized driving wheel, which is used for
travelling at great speed-In Fig. 2 is shewn the tubular form of railway before
inentioned, with the Cars inside.-In this figure E shews an ordinary carriage.
B. B. are the upper wheels running on the rails in the upper diagonal corners.
F represents the engine and driving wheels, the dotted lines in Fig. 2 indicate the
extra sized driving wheels. In Fig. 3 the construction of railway is shewn elevated
on ironwork supports, in the proposed mauner, for travelling over cities and towns,
and wherever such method is suitable.
Fig. 4 represents my system of railway construction, adapted to low levels and
underground travelling, which will be understood from the drawing; the under-
ground passages being fitted with the top protecting rails before mentioned.-In
Fig. 5 the arrangement suitable for a Station is shewn, in which the sides of. the
ironwork are dispensed with to afford convenience for entering and leaving the
trains. By supporting the roof H. of the platform with iron Columns G, the top
portion of the passage or railway can be held in position by brackets I or by other
Buitable means.
I wish it to be understood, that I do not confine myself to any particular shape
either in the form of the aforesaid Cars, or in the Class of materials used in their
construction, and that the Cars may be made with or without the aërial screws, or
may be propelled with or without locomotive engines, and that they may be made
in any manner preferred to secure the desired end, as hereinbefore mentioned and
described.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is :-
1. The method, means and appliances for securing rolling stock while travelling
at high speed, and preventing the same from leaving the rails, substantially as
herein before described and shewn on the drawings.
2, The general construction, combination and arrangements of the several and
respective parts, together constituting my improvements in railways, and in engines
and carriages therefor, and in means and appliances for propelling the same,
substantially as hereinbefore described and shewn on the drawings.
