5 Claims. (Cl. 246-477)
This invention relates to a safety signal device n
adapted to be placed on a rail of a track for the
purpose of indicating to the engineer or other
occupant of a train, the fact that the train should
5A be brought to a stop.
It is

and thus held against unauthorized re
With the foregoing and other objects in View
which will appear as the description proceeds,
the invention consists of certain novel details of
construction and combinations of parts herein
15 after more fully described and pointed out in
the claims, it being understood that changes may
be made in the construction and arrangement of
parts without departing from the spirit of the
invention as claimed.
20
In the. accompanying drawing the preferred
form of the invention has been shown.
in said drawing
Figure l is a view partly in side elevation and
partly in section showing the signal block in po
25 sition on a track rail.
Figure 2 is a plan view thereof.
Figure 3 is' a section on line 3-3 Figure 1.
Figure 4 is a perspective View of the filling block
forming a part of the device.
30
Figure 5 is an enlarged section on line 5_5
Figure 2.
Referring to they figures by characters of refer
ence, I designates an elongated block which is
formed of hard wood. This block has a straight
35 bottom face adapted to rest on a rail R. The top
of the block is gradually inclined as indicated at
2 so as to provide a high rear end 3 and a low
front end Il, the front end being preferably bev
elled as shown. The ends, top and sides of the
40 block are covered with metal sheathing in the
form of an inverted box 5 of sheet steel or the
like and this sheathing is held to the block by
means of transverse bolts or rivets 6 which are
embedded in channels 'I within the upper and
45 lower faces of the block. The channels are so
located and proportioned that when the rivets or
bolts are seated therein portions thereof will be
flush with and exposed within the respective upper
and lower faces of the block.
50
The sides of the sheathing 5 are extended
downwardly at the sides of rail R and are pro
vided with depending wings 8 adapted tov extend
between the ties T on which the rail R is mounted.
A key 9 is insertable transversely through these
55 wings and is adapted to be secured at one end by
a removable lock I0.
The other end of the. key
can be enlarged as shown so as to provide a
head II.
The key is located where it will extend under
the rail R after the block has been placed in 5
position. Consequentlyafter the key has been
secured by means of lock I0 it becomes impossible
to remove the block from the rail.
An opening I2 is extended downwardly through
the block I and its sheathing near the high end 10
thereof and this opening is adapted to receive
the shank I3 of a plate I 4 adapted to be used
as a flag or visual signal.
A ring I5 can be ex
tended from this plate for supporting a signal
lantern locked thereto if desired.
l5
The shank I3 has a hole I6 extending through
the lower end portion thereof. This hole is adapt
ed to receive a pin I7 which can be inserted into
the hole after the shank has been inserted down
wardly into the opening I2.
When the safety 20
signal device is placed on a rail the pin I‘I will
be housed within a recess I8 in the bottom of the
block and will prevent the shank from rotating
and from being withdrawn from the block as long
as the block is secured in position.
25
In practice the shank is fastened to the block
as explained and said block is then placed on a
rail at a point where it is intended to signal a
train. The block should never be placed on the
outside rail of a curve but should be used only on 30
a straight rail or on the inside rail of a curve.
Should a train pass the signal it would not be
derailed thereby. Instead one or more of the
wheels would ride on the block and drop off the
high end thereof back onto the rail. The severe 35
jolt to which the car would thus be subjected
serves as a signal to its occupant. The occupant
is also provided with a further signal in the form
of the ñag or plate I4 and, under some condi
tions, a lamp suspended from the ring I5.
40
Shank I3 can be of such a nature as to be bent’
over by the wheel of a car when travelling along
the block so that the jolting action heretofore
described will not be interfered with.
By arranging the bolts or rivets 6 so that they 45
will be iiush with the top and bottom surfaces of
the block I an important result is obtained.
Those bolts or rivets in the bottom portion of
the block constitute spaced non-yielding means
for gripping the top surface of the rail while the 50
bolts or rivets in the top portion of the block con
stitute spaced non-yielding means for engaging
and supporting the top or load carrying portion
of the sheathing.
It has been found in practice that the present 55
