Abstract
A rotary railway car coupler has a shank with a butt end portion for mounting to a coupler yoke and a head end portion on its opposite end portion. A coupler head has a guard arm side portion, a knuckle side portion and a knuckle mounted therewith for cooperative connection with another mating railway car coupler. The shank has on its head end portion a mount for rotatably mounting the coupler head. A mount within the coupler head rotatably connects the coupler head and the coupler shank for rotation of the coupler head relative to the shank.
Claims15
A railroad car coupler, comprising:
- (a) a shank having a butt end portion at one end for mounting with a coupler yoke and a head end portion at the opposite end, said head end portion including an axially extending peripheral bearing surface;
- and
- (b) coupler head means having a guard arm side portion, knuckle side portion and a knuckle for cooperative interconnection with an operable mating coupler having similar elements, said coupler head means further including an axially extending bearing surface complementary to said bearing surface of said head end portion of said shank, said respective bearing surfaces enabling relative motion to occur between said shank and said coupler head means;
- (c) means on said shank at said shank head end portion thereof to rotatably mount said coupler head means;
- and
- (d) means within said coupler head means to mount with said means at said shank head end portion to rotatably mount said coupler head means.

A railroad car coupler comprising:
- (a) a shank having a butt end portion for mounting with a coupler yoke and a head end portion on the opposite end portion thereof;
- (b) a coupler head means having a guard arm side portion, a knuckle side portion and a knuckle for cooperative interconnection with another mating coupler having similar elements;
- (c) means on said shank at said shank head end portion thereof to rotatably mount said coupler head means including, a substantially cylindrical exterior surface portion therearound, an annular shoulder extending inward of said substantially cylindrical surface and transverse to the longitudinal axis of said shank at the end of said substantially cylindrical surface facing said butt end portion wherein said cylindrical surface and said annular shoulder form coupling and mounting surfaces for permitting rotation of said coupler head means relative to said shank and for supporting said coupler head on said shank for draft action of said railcar coupler;
- (d) means within said coupler head means to mount with said means at said shank head end portion to rotatably mount said coupler head means including, an opening within said coupler head means having a portion of circular cross-section extending longitudinally of said coupler, an annular shoulder transverse to the longitudinal axis of said shoulder, extending inward of said circular cross-section portion and facing away from said shank butt end portion, and an opening in a rear portion of said coupler head means through which said shank head end portion extends into said coupler head means;
- (e) said knuckle is mounted with said coupler head means knuckle side portion and has a nose portion extending from said railway car coupler for cooperative interconnection with another railway car coupler, and a tail portion extending into the interior of said coupler head means;
- and
- (f) said means on said shank head end portion to rotatably mount said coupler head means has an opening within said shank head end portion to receive and rotatably mount said knuckle tail portion for rotating motion of said coupler head means including said knuckle tail portion relative to said shank and for mounting said knuckle for draft action of said knuckle.

In a railroad car coupler having a shank with a butt end portion for mounting with a coupler yoke and a head means located on the opposite end portion thereof with means to rotatably mount said coupler head means:
- (a) said shank has a head end portion that has a mid-portion with a substantially cylindrical surface therearound a smaller diameter inner peripheral portion and an internal shoulder therebetween facing said shank butt end portion;
- (b) said shank head end portion also has a longitudinally disposed opening therein communicating to the head end thereof wherein this opening has an annular portion to receive and rotatably mount a tail portion of the coupler knuckle including an internal annular shoulder around the periphery of the opening inside the shank wherein said shoulder faces said coupler butt end portion, said internal annular shoulder being adapted to cooperatively engage an oppositely facing surface on the coupler knuckle tail portion;
- (c) said coupler head means has a guard arm side portion, a knuckle side portion and a knuckle for cooperative interaction with another coupler having similar elements, however not necessarily being rotatable, said coupler head means including an opening through said coupler head means an opening therethrough having a portion of circular cross-section extending longitudinally of said coupler, and annular shoulder transverse to the longitudinal axis of said coupler, extending inward of said circular cross-section portion and facing away from said shank butt end portion, a second diametrically smaller portion of circular cross-section extending longitudinally of said coupler from the inner periphery of said annular shoulder and toward said shank butt end portion to the inboard end of the coupler head means to fit around the external peripheral surface of said shank;
- and
- (d) said knuckle is mounted with said coupler head means knuckle side portion and has a nose portion extending for cooperative connection with another railway car coupler and a tail portion extending into said shank opening, said knuckle tail portion is passable through said shank internal opening into its interior portion and has a partially annular surface operably engageable with said shank annular shoulder to facilitate load transfer between said shank and said knuckle during draft action of said coupler.
