WILLIAM ASBURY BLANKINSHIP .AND WILLIAM COPELAND, OF CORSICANA, TEXAS.
RAILROAD-CROSSING.
990, 799. Specification of Letters Patent. Patented Apr. 25, 1911.
Application filed September 26, 1910. Serial No. 583,899.To all whom it may concern:
Be it known that we, WILLIAM A. BLANIUN-
siIP and WILLIAM COPELAND, citizens of the
United States, residing at Corsicana, in the
5 county of Navarro and State of Texas, have
invented certain new and useful Improve-
ments in Railroad-Crossings, of which the
following is a specification, reference being
had to the accompanying drawings.
10 This invention relates to improvements in
railroad crossings, and more particularly to
that class of devices which are arranged in
combination with the crossing to reduce to
a minimum degree the noise which is caused
15 by the wheels of a train passing over the
rails at their intersecting points.
The primary object of our invention re-
sides in the provision of a device of the
above character which is of extremely simple
20 construction and may be installed in the
present system of railroad trackage without
requiring any change whatever in the ar-
rangement or construction of the crossing.
A further object of the invention is to pro-
25 vide a plurality of movable arms adapted
to be arranged between the inner and outer
rails, said arms lying flush with the tread
of the rails so as to provide a continuous
surface for the wheels in the passage of a
30 train over the crossing.
With these and other objects in view, the
invention consists of the novel features of
construction, combination and arrangement
of parts hereinafter fully described and
35 claimed, and illustrated in the accompanying
drawings, in which,-
Figure 1 is a - plan view of a railroad
crossing of the common construction show-
ing our device coperatively associated
40 therewith. Fig. 2 is a section taken on the
line 2-2 of Fig. 1. Fig. 3 is a section taken
on the line 3-3 of Fig. 1, and Fig. 4 is a
detail perspective view of the invention re-
moved from the crossing.
45 In the embodiment of our invention illus-
trated in the accompanying drawings, for
convenience in description, the characters N.,
S., E., and W. are applied to the north, south,
east and west ends of the intersecting track
o sections.
The outer and inner track rails R and R',
respectively, are arranged upon the ties T
and spiked thereto in the usual manner, said
ties being arranged upon a suitable founda-
55 tion structure. The rails running north and
south extend between the rails running eastand west, said rails, at their intersecting
points being arranged in sections, the ends
of the sections of the north and south rails
being disposed in the same plane as the inner 60
opposed edges of the rails running eas, and
west so as to afford an unobstructed passage
for the wheels.
Between the inner and outer rails and
upon each side of the rails running at right 65
angles thereto, our device is arranged. The
same comprises the arms 5 which are en-
larged at one end, as clearly shown at 5' in
Fig. 4, and are rigidly secured upon a rod
6 which is mounted to rotate in the webs of 70
the outer rails R. These arms are disposed
for movement into and out of the space be-
tween the opposed longitudinal edges of the
inner and outer rails. One end of each of
the rods 6 upon which the arms 5 are fixed, 75
is formed with a crank 7, and these cranks
are connected by a rod 8 which extends be-
neath the rails which are disposed in parallel
relation to the rods 6 to which said connect-
ing rod is connected. The ends of the rod 80
8 are bent upwardly at right angles, as shown
at 9, and are provided with eyes through
which the ends of the cranks 7 extend.
From reference to Fig. 1, it will be noted
that the arms 5 are of sufficient length so 85
that when in their operative positions be-
tween the inner and outer rails which run
north and south, the ends of said arms will
be flush with the ends of the rail sections
and with the inner longitudinal edges of 90-
the outer rails running east and west. The
other pairs of arms which are arranged be-
tween the rails running east and west ex-
tend inwardly to the inner longitudinal
edges of the north and south rails when in 95
their operative positions. Thus it will be
seen that a continuous supporting surface
for the tread of the wheels is provided be-
tween the spaced inner and outer rails of
the crossing. In this manner the noise coin- 100
only heard by the passage of a train over a
railroad crossing is to a great extent elimi-
nated. To one end of each of the connect-
ing rods, a rod 10 or other actuating element
is secured. Any desired means, such as elec- 105
tricity or compressed air may be provided
for operating the rod 10 to rotate the rods
6, and move the arms 5 to their operative
and inoperative positions.
In Fig. 1 of the drawings the arms are 110
shown arranged for the passage of a train
over the rails running east and west, the
