PROVISIONAL SPECIFICATION.
Improvements in or connected with Rail Joints for Railways and
Tramways.
I, ALEXANDER SCHWARZSCHILD of Frankfort on Main in the Empire of
Germany Engineer do hereby declare the nature of my invention to be as
follows:-
The object of the present invention is to provide rails for railways and tramways
wherein the ends of the rails at the joints between two adjacent lengths of rail are
so fashioned that the jarring and vibration caused in the rolling stock by the joints
as hitherto arranged are obviated. Rails have been hitherto made with the ends
of adjacent rails cut away at reverse sides so that a joint is formed which does not
extend right across the rail at any one place but each joint is made to extend half
across the rail at two places. The wheels of the vehicles when they pass over the
joints receive a jar or transmit vibrations to the vehicles and to obviate this the
surfaces of the top ends of the rails are sunk or cut away so that they gradually
descend towards the joints in such a way that the joint ends of the rails are beneath
the general surface of the rails and cannot come in contact with the wheels as
the wheels will at these sunken or cut away parts be resting upon the uncut away
portions of adjacent rails.

Improvements in or connected with Rail Joints for Railways and
Tramways.
I, ALEXANDER SCHWARZSCHILD of Frankfort-on-Main in the Empire of
Germany Engineer, do hereby declare the nature of my 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 the present invention is to provide rails for railways and tramways
wherein the ends of the rails at the joints between two adjacent lengths of rail are
so fashioned that the jarring and vibration and consequent wear and tear caused
in the rolling stock by the joints as hitherto arranged are obviated. Rails have
been hitherto made with the ends of each of the adjacent rails cut away at reverse
sides as shewn in plan with regard to one rail in Figure 1 of the accompanying
drawings so that a joint is formed which does not extend right across the rail
at any one place but each joint is made to extend balf across the rail at two
places.
The wheels of the vehicles when they pass over the joints receive a jar or
transmit vibrations to the vehicles and to obviate this the surfaces of the top ends
of the rails are sunk or cut away so that they gradually descend towards the joints
in such a way that the joint ends of the rails are beneath the general surface of the
[P. 27

page_text: rails and the wheels cannot come in contact with the said ends as the wheels will
at these sunken or cut away parts be resting upon the uncut away portions of
adjacent rails above the level of the joint ends.
Figure 3 of the accompanying drawing represents in plan and Figure 4 in
perspective a joint made according to this invention.
Figure 2 is a plan of one of the rail ends separately.
Figures 5 and 6 are transverse sections respectively taken on the lines 1, 2
and 3, 4 of Figure 3.
The portions of the top ends of the rails which are sunk or cut-away as aforesaid
are marked x, the joint ends a thus being beneath the surfaces b which are in line
with the general surface of the rails so that the wheels as they run on the surfaces b
pass over the joint ends a without coming in contact therewith.
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 :-
:-
Railway rails having their ends formed as described and with sunken or cut-
away parts, or inclines, at the joints substantially as, and for the purpose,
berein before described.
