To all whom t may concern:

Be 1t known that ll, ENoor-r GEORGE, J r.,

a citizen of the llnited States, residing at in the art to which' it appertains to make ment.

`and wedg'ing and use the same.

My invention relates to a car coupler and draft yoke connection for railway draft appliances, and is designed to afford simple, strong and efficient means permitting couplers of the type primarily intended to be connected to the draft yoke without capability of lateral swinging movement to be pivotally connected to' the draft yoke so as to be ada ted to have such a swinging moveenerally stated, the 4preferred embodiment of my invention by which this object is accomplished involves a coupler Ahaving a stem, a draft yoke which is provided at its forward end with alined pivot lugs, and a memberintermediate of the cou-. pler and oke formed with a centrally disposed soc et for receiving the rear end of the coupler stem and alsoprovided with spaced slotted arms which receive the coupler stem between4 them, the rear end of the intermediate member having pivot lugs which mesh with those of the yoke and which are adapted to receive a pivot pin connecting the intermediate member to the yoke, key means, which fextend throu h the slots of the coupler stem and interme iate member, being provided for attaching the coupler to said intermediate member.

sembled position the downwardly removable pivot pin by which the intermediate member is pivotally connected to the yoke.

ln the drawings, 1 is the stem of af car coupler and 2 is a draft yoke. The stern of the coupler is provided near its rear end with a transversely extending slot 3 which is adapted to receive key means for connecting the coupler to the intermediate member a of the device.

'llhe yoke is provided with longitudinally extending arms 5 which are spaced apart to receive a cushioning unit (not shown) in the well known manner. At their forward ends the arms of the yoke are fashioned with pivot lugs 6 which preferably are formed with flat transversely extending front and rear faces and whose perforations are adapted to receive a vertically extending pivot pin 7; rlllhe rear faces S of these pivot lugs Patented Nec. ,6, i921.

are adapted to engage the forward end of the cushioning unit carried between'the yoke arms 5.

The intermediate member 4C is preferably formed with a centrally disposed forwardly opening socket 9 which receives the rear end of the coupler stem l, and at its rear end and in horizontal alinement with the socket said intermediate memberis also preferably provided with a perforated lug 1() which extends between the pivot lugs 6 of the yoke and whose'rear face 11, like the faces 8 of the yoke' pivot lugs, is adapted to engage.- the forward end of the cushioning unit. At the base or inner end of the socket 9 the intermediate member l is provided with a wall or face l2` against which the rear end of the coupler stem y1 is adapted to bear, so that bufling shocks received by the car couler are transmitted therefrom to the cushioning unit ldirectly through the centrally disposed lug 10. ln addition to the pivot lug l0 the member 4 is preferably provided at its rear end with pivot lugs 13 vwhich are spaced directly' from the lug 10 sufliciently to receive the pivot lug 64 at the forward end of the draft yoke, the rear faces of the intermediate member between the central lug 10 and the outer pivot lugs 13 being beveledto afford clearance for they flat forward face ofW'the pivot lugs 8 of the yok'e when the coupler swings laterally. As the `downwardly removable pivot pin 7 extends through the outer pivot lugs 13 as well as lil@ l spending tothe transversely extending slot` central 4pivot lug of the member e, the pin is placed in quadruple shear and thus offers great resistance to failure.

T he intermediate member -1 has at its forward end oppositely disposed spaced arms 1-1 which receive the'eoupler stem between them and which have alined slots 15 correwhich respectively overlap the outer faces of the slot-ted arms 14. at their forward ends, while. the adjustable wedge 17 is formed at one end with a.threaded stem 19 for receiving a nut `2() which bears against the outer face `of the adjacent arm 14 of the intermediate member and which by being r0- tated serves to adjust the position of the wedge 17, thereby forcingthe `wedge 416 forwardly so as to prevent longitudinal movement of the coupler. stem 1 with respect to the intermediate member 4 and at the same time coupling the slotted arms 14 togetherv in a manner 4resisting their spreading.

As a convenient means for retaining the pivot pin 7 in assembled position, it is pretion between its ends b reason of which it' ferred `to provide the lower pivot lug 13 of the intermediate member with a air of downwardly extending lugs 21 which are disposed uponopposite sides of the pivot pin opening of theY lug ,13. Pivotally mounted on the lugs 21 and extending therebetween is a latch bar 22 which is adapted to extend under and support the pivot pin 7. The latch bar 22 has an eccentric pornormally tends under t e influence of gravity to remain in the assembled position illustrated'in' Fig. 4. In order to provide for the assembly and removal of the latch bar 22, one of the supporting lugs 21 is fashioned with a horizontally extending slot 23 through which the member 22 may be inserted or withdrawn. The companion lug 21 is simply Lesser/je@ provided with a circular aperture of suitable size to receive the cylindrical end er pintle of the latch bar 22.

1. in a coupler and yoke connection, the combination with a coupler having a stem,

of a yoke, a member intermediate of said yoke and coupler provided with spaced arms adapted to receive the stem of said coupler between them, means for pivotally connecting said intermediate member to said yoke, and means for connecting the stem of said coupler to said intermediate member, said last named means being adapted to engage said spaced arms and to resist lateral spreading thereof'.

2. In a coupler and yoke connection` the combination with a coupler having a slotted stem, of a draft yoke, a member intermediate of said coupler and yoke and pivotally connected to the latter, and ke'v means for connecting said coupler and intermediate member, said intermediate member being provided at its forward end with oppositely disposed slotted arms adapted to receive the stem of said coupler between them, and said key meanscomprising a pair of wedge members extending into said slots of said coupler stem and intermediate member, one of said wedge members having lugs which iespectively overlap the outer faces of said slotted arms at the forward ends of said arms.

3. In a coupler and yoke connection, the combination with a coupler having a4 slotted stem, of a draft yoke, a member intermediate of said coupler and lyoke and pivotally conncted to the latter, and key means for connecting said coupler and intermediateI member, said intermediate member being provided at its forward end with oppo- `sitely vdisposed slotted portions adapted to receive the coupler stem between them, and

said key means eomprising a wedge member extending through sai stem and intermediate member and havin atA its ends forwardly extending lugs em racing the said slotted portions of the intermediate member ybetween them, an adjustable wed e member engaging the rear face of said rst named wedge and extending through said coupler stem and intermediate member, and an adjusting nut interposed betweensaid intermediate member and said adjustable wedge.
