ing member, the latter will be forced to the
right against the opposite guide bar, thus
throwing the switch point over against the
main line rail and permitting the car to go
5 straight ahead on the main line. On the
other hand, when the switch point is in the
latter position, so that the main line track
is completely open, and it is desired to send
the car onto the siding, the operating rod 32
10 is inserted in the opening 30, thereby allow-
ing the lower end thereof to pass into the
mouth provided between the active face 14
and the face 33 of the actuating member so
as to cause the latter to be wedged over
15 against the guide bar 11 to draw the switch
point in the same direction thereby allowing
the car to run onto the siding. It will be
seen that no lateral strain will come to bear
upon the operating rod as it passes through
20 the respective channels provided between
the actuating member and either one of the
guide bars, and that the car will be forced
onto the siding when the switch point is
thrown into the position shown in Fig. 3
25 due to the action of the wheels on the right
side of the car trucks against the outer edge
35 of the said switch point. It is to be
further noted that cars passing in the op-
posite direction will not be able to operate
30 the switch point because the operating rod
when inserted in one of the plate openings
will not engage the body member which is
located out of the path of movement of the
said rod, thus eliminating the danger of the
3 switch point being thrown accidentally by a
train passing in the said direction.What is claimed is:
In a device of the class described, in com-
bination a movable switch point, a plurality
of transversely extending guide plates lo- 40
cated beneath the track rails and having a
space provided between adjacent plates, a
longitudinally extending actuating member
mounted upon said .plates for transverse '
sliding movement at one side of the track 45
center and bridging the said space, a lateral
flange being provided on said switch point,
an attaching plate being disposed for slid-
ing movement within the said space between
the supporting plates and having one end 50
rigidly secured to said switch point flange
and the other end rigidly secured to the base
of said actuating member, and converging
guide bars secured to said plates at either
side of the said member and bridging the 55
said space, the outermost of said guide bars
being located above the attaching plate, the
ends of said guide bars being beveled out-
wardly to form mouths with the ends of the
actuating member which are beveled to form 60
points, said guide bars adapted to guide a
train carried operating rod into active en-.
gagement with the said member to throw
the switch point, and further serving to
limit the transverse movement of said mem- 65
ber.
In testimony whereof I affix my signature
in presence of two witnesses.
