COMPLETE SPECIFICATION.
Improvements in the Permanent Way of Tramways and the like.
I, ARTURO HEEREN of 95 Boulevard Beaumarchais, Paris in the Republic of France,
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 :-
The present invention relates to improvements in the construction of the rails for
tramways and the like and its object is to prevent the formation of ruts which generally
exist on each side of the rails in consequence of the other vehicular traffic along the
route, and by the present arrangement all sliding and jerking of the vehicles in
consequence of the difference between the road and the rails are prevented.
To obtain this result I construct my rails so that the part which is in contact with
the paving of the road is recessed on the side so that the paving stones or other
paving material can be placed in these recesses and the projecting parts of the rails
will protect the paving from the settling or sinking due to the passage of the other
vehicles.
In the accompanying drawings ;-
Fig. 1 represents a plan of the rail.
Fig. 2 represents a perspective view of the rail in elevation.
Fig. 3 represents a transverse section of the rail through one of the recesses.
The rails A where they are in contact with the paving are provided with
projections B of the size of the paving stones or blocks, and these projections are
placed so far apart as to form recesses of the size of the paving stones or blocks. The
rows of paving stones or blocks standing perpendicular to the rails will correspond
alternately with the projections and the recesses and in this manner the projections of
the rail will protect the first paving stone or block of each row, thus avoiding the
formation of ruts along the rails. These ruts are always disagreeable and sometimes
even dangerous to the other vehicular traffic passing along the same road. The
recesses in the rails may be formed in any suitable or desired manner, either in the
rolling mill, or stamped out or otherwise.
The accompanying drawing represents the invention as applied to a double rail,
but it may of course be applied to any other known form. In case the section of the
rail should be rectangular the recesses would be formed the whole height of the rail
which thus would resemble a kind of rack.
If the permanent way consists of two single rails only, these recesses may be formed
on each side of each rail i.e. on the interior and the exterior of the permanent way.
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 improvements in tramways and the like consisting in the formation of
projections and recesses on one or both sides of the rails substantially as and for the
purpose described.
2. A permanent way for tramways and the like in which the paving intercalates
with the rail substantially as and for the purpose described.
