arms which are arranged in the east and
west track being in their inoperative posi-
tions and below the tread of the rails so that
they are disposed entirely out of contact
5 with the wheels, said latter arms resting
upon the foundation structure which sup-
ports the crossing.
From the foregoing it is believed that
the construction and operation of our in-
10 proved railroad crossing device will be
readily understood. It is apparent that the
device may be constructed at a very low
cost and requires no change whatever in the
ordinary construction of crossing in its
15 installation. The device is moreover ex-
tremely efficient in operation, and owing to
the few elements employed in its construc-
tion, the cost of repairs is rendered very
small. ,
While we have shown and described the
required construction and arrangement of
the various parts, it will be understood that
the device is susceptible of a great many
25 minor modifications without departing from
the essential features or sacrificing any of
the advantages thereof.
Having thus described our invention,
what we claim is:
30 1. The combination with a railroad cross-
ing comprising spaced inner and outer inter-
secting rails, of arms arranged in the space
between the inner and outer rails running
in each direction, rods rotatably journaled
35 in the webs of the outer rails, said arms be-
ing rigidly secured on said rods, connect-ing rods between the ends of the rotatable
rods arranged in each pair of rails, and an
actuating element connected to said connect-
ing rod to rotate the first named rods and
position the arms between the spaced inner
and outer rails, the inner ends of said arms
being flush with the inner longitudinal edges
of the outer rails running at right angles
.thereto, substantially as and for the pur-
pose set forth.
2. The combination with a railroad cross-
ing comprising spaced outer and inner inter-
secting rails, of rods rotatably journaled in
the outer rails, arms fixed upon said rods
adapted to lie in the space between the
inner and outer rails and flush with the
tread surface thereof, the inner ends of said
arms being disposed in the same plane as
the inner edges of the outer rails running at
right angles thereto, cranks formed on the
ends of said rods, connecting rods between
the cranks of the rods journaled in the
rails, and actuating elements connected to
said connecting rods to rotate the said first
named rods and move the arms to their op-
erative and inoperative positions substan-
tially as and for the purpose set forth.
In testimony. whereof we hereunto affix
our signatures in the presence of two wit-
nesses.
