PROVISIONAL SPECIFICATION.
Improvements in the Sections and Forms of Iron Rails, in the
Method of Laying them, and Placing within them an Electric
Conductor, and in the Manner of Applying the Electric Brush
of an Electric Motor to the aforesaid Electric Conductor for use
on Electric Tramways and Railways.
HENRY JAMES PEDDIE Engineer Tynecastle Iron Works Gorgic Road
Edinburgh. I do hereby declare the nature of this invention to be as follows:-
laid alongside of one of the ordinary rails Z Figs. I. II. III.
II. FOR USE WHEN ONE OF THE ORDINARY RAILS IS DISPENSED WITH.
In this case the rail A. Fig. IV., is laid in place of one of the ordinary rails,
and along side of it an angle iron rail or guard, B. The rail A in this case serves
for the wheels to run upon, the ordinary rail being dispensed with.
The rail or guard B. may if desired be dispensed with, the groove A. being
simply formed, by the stones of the causeway, in the case of street tramways.
III. AS TO THE POSITION OF THE CONDUCTOR AND AS TO THE BRUSH.
In all cases described under I. & II. wood or other non conducting material C.
Fig. V. is fixed as shown, inside the rail and the conductor D attached to it.
From the motor or car an insulated bracket E with a conductor G. is suspended,
to which is attached a brush F. which travels over the conductor D. The brush
gathers up the electric current, which then passes up the bracket E, and the con-
ductor G., and operates the motor, returning to earth through the axle, wheel, and
opposite rail. The brush F can be raised or lowered on E, and is kept in position
on it by an ordinary pinching screw.
A small wheel may be used instead of the brush F.
By the use of the rails, and the arrangement of the conductor & brush, above
described, electric tramways can be laid and worked with perfect safety on public
streets, & also with safety from accident from the electric current, on electric
railways. Arrangement No. I. is designed for being used for ordinary horse tram-
ways already laid, & arrangement No. I is intended principally for new lines. In
both cases, the necessity for a conductor or rail midway between the rails on the
street, (which would be a great inconvenience to horse traffic) is avoided, whilst
the position of the conductor inside the rail, as has been said, secures against
accident from the current.

Improvements in the Sections and Forms of Iron Rails, in the
Method of Laying them, and Placing within them an Electric
Conductor, and in the Manner of Applying the Electric Brush
of an Electric Motor to the aforesaid Electric Conductor for use
on Electric Tramways and Railways.
HENRY JAMES PEDDIE Engineer Tynecastle Iron Works Gorgie Road
Edinburgh. I do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
T
The rails may be either of iron or steel.
Iron or steel cases tenned "mud traps," with movable top cover and connected
by underground pipes, with the street gutters or drains, may be placed (opposite
apertures in the web of the rail A) at suitable distances. These permit of the
interior of the rail being easily cleaned and of the conductor being renewed, without
breaking up the permanent way.
The insulator within the rail, may be of tee shape with single or double cup, to
prevent "creeping," or of any other form or shape most suitable. The required 4
section of rail may be obtained by the rail being either rolled or cast. to the
required section, or by it having the vertical side flange, or guard, rivetted on to
the top flange.

page_text: Having now particularly described & ascertained, the nature of my said inven-
tion, & in what manner the same is to be performed I declare that what I
claim is
1. The section of rail shown in Figs. I. II. III. IV. V. of Sheet No. I. left
with the Provisional Specification, and consisting of bottom flange, vertical web,
top flange, and vertical side flange or guard from top flange.
2. The method of utilizing the aforesaid section of rail, as a conduit for an
electric conductor, and also as a combined ordinary wheel rail, and conduit
(irrespective as before declared of any particular form of internal insulator, or of
any particular arrangement for cleaning the rail internally) all as previously herein
described.
3. The method of placing the electric conductor within the rail A. so that the
brush can be applied to the under side of the electric conductor, exclusive however,
as before declared, of any particular form or shape of internal insulator.
