v This invention relates to railway car coupler
In the drawings, l indicates an operating rod
for an Association of American Railroads stand;
ard “E” coupler, which rod is provided at its outer
end with a depending handle portion 2 and at
operating mechanisms, operable from the side
of the car, and the principal object of the inven
tion is to provide an operating rod having a
handle at its outer end normally non-rotatably
its inner end with a hook portion 3 connected to
an eye 4 of the rotary lock lifter 5, pivotally con
nected at one end, as at 6, to the link 1 which
supported by a bracket on the end of a car and
having means at its inner end for attachment to
lifts the lock of the coupler 8 upon swinging of
the lock lifter and thereby operates the coupler.
Adjacent the handle portion 2 the rod is sup

tation of said rod said lock lifter is swung to
raise the coupler lock and thereby operate the
coupler.

The trend of railway freight train operation is

Another object is to so form the supporting
bracket that when the rod handle is released by »
the trainman the operating rod will automatically
return to its non-rotatable position therein,
The desirability of normally non-rotatively
supporting a coupler operating rod has been rec
ognized in the prior art, but in most instances L", Ll
known to applicant, it is necessary for the rod to
be elevated out of its held position before it can
be rotated. This is objectionable because it re
coupler lock and thereby uncouple cars of a mov
ing train.‘ To prevent such an occurrence, I
have designed my operating rod so that in normal
operation, i. e., at all times other than when the
coupler is to be operated to'uncouple a pair of
cars, said rod is non-rotatably held in its sup
porting bracket. Consequently the handle can
not “whip” due to said inertia and thereby un—
lock the coupler. This is accomplished by pro;
viding a non-circularrportion in the rod adjacent
the handle, which said portion is elongated in
section (Fig. 3) and provided with a downwardly

The bracket for therod comprises a supporting
plate H which is provided with spaced holes l2
through which bolts or other attaching means
may secure said plate ‘to a ?xed part of the end
of a car, as, for example, the brace I3. The plate
H is bent at slightly more than a right angle,
as at M, forming a flange portion 15. A some

Other objects and advantages of the invention

Referring now to the accompanying drawings

reference characters indicate like parts:

what ea‘rl-shaped opening I!) is formed through
the ?ange portion l5, which opening is counter
sunk‘ from opposite sides of the plate so that when
the operating rod is supported therein it may
have a substantial pivotal movement caused by
a movement of the coupler longitudinally of the
car. The lower part of the opening [9 is re
stricted, being elongated or notched downwardly,
as at 20, and having downwardly tapering sides,
to non-rotatively receive the lobe IU of the rod I,
where the rod normally rests, as shown in Fig. 5.
The upper part of the opening is larger, provid-.
50 ing enough arear for the rod to rotate suihciently
to operatethe coupler, and it will be noted that
‘ upon the ?rst movement of the operating rod

ments of said car, said bearing surface, guiding
surface and rod being associated and arranged
the trainman to ?rst raise the rod out of the
lobular or restricted part of the opening before
turning the rod to operate the coupler. This is
due to the fact that the center of rotation 22 of
the rod is above the ?rst line of contact 23 of
arcuate surface 2| and consequently when the rod
is rotated it will not bind against the tapered

guiding surface causes said portion of said rod
to roll and slide upon said bearing surface out of
