RAILROAD RAIL AND JOINT.
SPECIFICATION forming part of Letters Patent No. 247,978, datedOctober 4,1881‘.
Application ?led September 6, 1881. (No model.)
To all whom it may concern :
.
Be it known that I, JAMES WoLFENDEN, a
citizen of Great Britain, residing in Look Ha
ven, Clinton county, in the State of Pennsyl
vania, have invented certain new and useful
Improvements relating to Railroad Rails and
Joints, ofwhich the following is a speci?cation.
My improved joint is of that class in which
IO
a portion of the metal of each rail is removed
and the rails caused to overlap each other or
splice together.

The invention consists in the manner in
7
'if the ?rst of a» given line of rails is placed
with its web out of center to the right, the
second rail in that'line which abuts or joints
against it at the‘ end is reversed in position, so
that its web is out of center to the left. The
third is again out of center to the right, and 55
so on alternately.
The rails may be all formed
in the same rolls and exactly alike, care being
taken to'simply place them alternately end
for end. The webs are formed just so much
out of center that one face of each- web is in
the central line of the ra-il., These faces are
which the rails and clamps are formed and ?t made plane.

necessary to distinguish them.
A’ is the head. A2 is the broad base, some
times known as the “ ?ange,” and A3 is the up-‘
right portion joining the ?ange and the head,
universally known as the “web.” The web A3,
instead of being centrally placed in the rail, is
placed one side of the‘ center. ‘In order to

each of which 'I will designate, when necessary,
