PROVISIONAL SPECIFICATION.
Improvements in Permanent Way for Railways and Tramways.
I, ARTHUR JAMES HAMILTON-SMYTHE, of 9, Victoria Street, Westminster,
London, S. W., Civil Engineer, do hereby declare the nature of this invention to
be as follows:-
.
An improved method of forming permanent way for railways and tramways by
placing bent metal plates at the sides and partly below the level of the rails, by
connecting these plates together in pairs with bolts or tie-rods and by then using
cement concrete in combination with the bent plates and bolts or tie-rods for
securing the rails in their required positions and for supporting them from the
road-bed.
Dated this Twelfth day of December 1894.

Improvements in Permanent Way for Railways and Tramways.
I, ARTHUR JAMES HAMILTON-SMYTHE, of 9, Victoria Street, Westminster,
London, S.W., Civil Engineer 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:-
Figures 1 and 2 on the annexed sheet of drawings represent the essential parts
of side elevations of permanent way for railways or tramways formed in accordance
with my invention, and Figures 3 and 4 represent cross sections of the same.
The
same letters of reference indicate corresponding parts in all the figures. In order
to lay permanent way for railways or tramways according to my invention, having
graded and levelled the road bed or any convenient surface H, lay thereon the
metal tie-rods A at the requisite distances apart, then thread the bolts B through
the holes in the pairs of bent and perforated metal plates C. Engage the lower
edges of the said plates C in the hooked ends of the tie-rods A.
Insert temporary
moulding boards, or blocks, or plates, in the intervals between the pairs of
permanent bent and perforated metal plates C in order to assist the said permanent
plates in temporarily enclosing a hollow space, or spaces, of the required shape, or
shapes, and dimensions, and then fill in and ram or pack the hollow space, or spaces,
thus formed with cement-concrete D. When the said concrete D has sufficiently
set or hardened place the perforated railway or tramway rails E in their positions
by passing holes drilled through the said rails at the required intervals on to the
ends of the bolts B. After this affix the required perforated fish plates, or washer-
plates, F to the outsides of the rails E by passing the holes in the plates F on to
the ends of the bolts B and finally screw the nuts G along the screw ends of the
bolts B till the nuts G press tightly against the fish-plates or washer plates F
either with or without the interposition of ordinary spring washers J.
In the case of substituting for existing sleepers in already working railways or

page_text: tramways concrete blocks already moulded in metal plates bent to suit the existing
rails in accordance with my invention, then the existing rails can be removed from
the existing sleepers and the plated concrete blocks can be substituted for the said
sleepers on the road-bed. The existing rails, having previously been drilled with
new holes if and where required, can then be attached to the said plated concrete
blocks as herein before described and the spaces left intervening between the several
plated concrete blocks can be filled in with cement concrete under and between the
rails so as to form a continuous bed of concrete if desired.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is '
The method hereinbefore described and illustrated by the annexed drawings of
forming permanent way for railways or tramways by affixing suitably bent metal
plates similar in form to those illustrated in the annexed drawings to the sides and
partly below the level of railway or tramway rails so as to assist both in supporting
the rails above the road-bed at the requisite distances from each other and also to
assist in confining cement-concrete while plastic within a limited space, or spaces,
in the requisite forms and positions for assisting when set the said bent metal plates
and bolts or tie-rods, or both, or either of them, to support and secure the said rails
in the permanent way, substantially in the manner herein before described and
illustrated in the annexed drawing.
Dated this Nineteenth day of December 1894.
