J. F. O'CONNOR COUPLER CONNECTION Filed May 12.. 1928 w 4 7 0 WI l l i 4 VL\ Z f Patented Feb. 18, 1930 JOHN F. OCONNOR, OF CHICAGO, ILLINOIS, ASSIGNOB. TO W. H. MINER, ING, OF CHICAGO, ILLINOIS, A CORPORATION OF DELAWARE COUPLER CONNECTION Application filed 'May' 12, 1928.

'15 Another object of the invention is to provide a coupler connection of the character indicated, wherein the coupler shank is swiveled to a pressure-transmitting block, the pressure-transmitting block and the butt end of the coupler shank being provided with cooperating bearing means, including a cylindrical bearing member on one of the parts and a co-operating bearing socket on the other part, adapted to be assembled by inserting the 2 bearing member within the socket in a lateral direction, the parts being maintained in assembled relation by the usual coupler key which extends through the coupler shank and cylindrical member, locking the same against lateral separation but permitting relative swinging movement thereof.

Other and further objects of the invention will more clearly appear from the description and claims hereinafter following. a

' In the drawings,'forming a part of this specification, Figure 1 is a horizontal, longif tudinal, sectional view through a portion of the railway draft rigging of a car, illustrating my improvements in connection therewith. Figure 2 is a longitudinal, vertical, sectional view, corresponding substantially to the line 22 of Figure 1. AndFigure 3 is a top plan view of the inner end of the coupler and co-operating parts, illustrating a different embodiment of my invention.

Insaid drawings, referring first to the embodiment of the invention illustrated in Figures 1 and 2, 1010 indicate the usual channel-shaped center or draft sills of a railway car underframe, to which are secured cheek Serial No. 277,269,

plates 11 provided with key receiving slots 12 and 13'. The striking casting of the railway draft rigging is indicated by 14, and the usual carry iron which supports the coupler shank is designated by 15. A wear plate 16 is disposed between the'carry iron member 15 and the coupler shank. A yoke 17 of the horizontal type is disposed between the draft sills, the front ends of the side'arms of the yoke member only being illustrated in Figure 1 of the drawings. The usual front follower block is designated by 18 and is provided .with a transverse key slot through which the follower key 19 extends. The yoke 17 has the arms thereof provided with

slots

20 and 21, which are of the usual form. The follower block key 19 extends through the slots 21 of the yoke and has the outer ends thereof working in the slots 13 of the cheek plates.

In carrying outmy invention as illustrated in Figures 1 and 2, I provide, broadly, a coupler A, a pressure-transmitting block B, and a coupler key C.

The coupler A is provided with the usual horn, not shown, from which extends a' shank 22. As shown, the coupler shank 22 tapers rearwardly and has the butt end thereof enlarged, the butt end section being cut away centrally to provide spaced, rearwardly extending, inwardly curved arms 23-23. As clearly shown in Figure 1, the inner faces of the arms 23 are curved, as indicated at 2 1, so as to provide a substantially circular pocket The free ends of the arms28 are spaced apart, as shown, and present substantially flat radial end faces 3333 which, as hereinafter pointed out, act as limiting stops to limit the lateral swinging movementof the coupler. The rear end faces of the arms 23 are also curved, as indicated at 25/ These faces are concentric with the curved surfaces 24 on theinner sides of the arms. Immediately adjacent the curved face '25, each arm I 23 is provided with a substantially fiat, longi tudinally extending face 26. Midway between the ends of the enlarged section of the coupler butt, the sides thereof are provided with curved projections 27 which substantial 1y fit between the side arms of the yoke member. The faces of the curved projections 27 are concentric with the curved faces 24', so that the coupler may swing between the arms and the yoke without interference. V

' The pressure-transmitting block B comprises amain bodyportion having a fiat transverse end face 28 which bears directly forming a bearing member.

side faces of the post 29 are flat, as indicated i at 313 1, and converge forwardly, the same.

on the front face of the follower block 18. The body portionmof the pressure-transmit.- ting blockis provided with aforwardly projecting, relatively heavy post 29-, having acylindrical head 30 at the forward endthereof The opposite being preferably radial-to the-center ofthe pocketin the butt" end of; the coupler shank.

[fits within the pocket formed by the curved 20 As shown; the cylindrical bearing section 30 side walls 24524 ofthe arms 23, so that the couplerwillhave pivotal movement on said bearingmember.f 'At opposite sides, the front end portion-of the pressure-transmitting blockzproper is cutaway, thereby providing concave bearing walls: 32-32 'on opposite sides of said block, which areconcentric with the curved walls 24 of the arms. The. inner ends of the arms 23 fit between the cylindrical bearing element 30 and the curved bearing wa1ls132 of the pressure-transmitting block, so that the arms will bear on both the f v cylindrical bearing element and the bearing walls 5.32, the curvaturef'of the end bearing fac'es25 of the arms being thesa-me asthat of the walls 32. i M

'fAs shown in Figure 1 the fiat end abutment L surfaces 33 of thearms23are spaced from the abutment'faces 31 ofthe post 29 such a distance that the coupler has the required amount ofradial swinging movement. When the coupler has been swung toeither side of centered position a predetermined distance,'the abutment face33' at the inner end of one of the arms engages the corresponding side face 31 of thepost29, thus positively pler.

limiting the swinging movement of the con- B has been described las-a member separate 7 from the coupler l 'shank, it in fact forms a: separable butt end member of the coupler J shank, thecoupler shank being of two-part construction, the parts of which have swiv Although the pressure transmittingblock cylindrical bearing section 30 and the front end portion of the post 29 of the pressuretransmitting blockBare also provided with a slot 35 which is adapted to accommodate the coupler key C, the slot 35' registering with the slot 34 when the pressure-transmitting block is assembled with the coupler shank.

The key C extends through the aligned slots 34 and Y35, the key receiving slots of the arms of the yoke and the key receiving slots '12 of the cheek plates of the draftsills. As shown, the key G is headed at one endand is providedwith a retaining element of well known form, indicated by 36,-: at the otherv end. V In assembling the parts ofmytimproved coupler connection as illustrated in Figures 1; and 2,. the 'cylindrical bearing element of the pressure-transmitting block and the arms 23-of the coupler shank are inter-engaged-by bringing the bearing'element 30 in alignment with a pocket provided between the arms 23 and then passing the same into said pocket and the inner ends of the arms-23 into the space between the cylindrical bearing element and the walls 32"ofthe pressuretransmitting block B by moving the coupler shank and the pressure-transmitting block laterally toward each other in a vertical die, I

re'ction until the key receivingjopenings 34 and 35 of the coupler shank and the pressuretransmitting block B are brought intoalignment. When the-parts have been: thus assembled, the coupler 1 shank is connected to the 'preSsure transmitting block for pivotal movement so that-the coupler shank may swing laterally. Whenthe part-s have been thus far assembled, the key C is inserted throughthe openings in the ,draft sills; the

arms of the yoke andthe aligned openings 34' and 35'of the coupler-shank and pressure:

transmitting block B. Aswill be evident,

when the key has been thus inserted,'the parts A and B are held againstseparation-in' a ivertical direction thus holding the coupler shank and pressure-transmitting block positively assembled. When it is desired to 'remove the pressure-transmitting block B from.

the coupler shankjhe keyG is withdrawn, thereby permitting vertical;.separation of the and the 'pressure-transmitting block .BL

In the operation of my improved coupler connection, the shank of the-coupler has' a bearing elements of the swiveled; connection: between the lnner end of the coupler shank 1 swiveling movement on the bearing Emember 30 'and the bearingwalls 32 of the pressuretransmitting block, the lateral swinging movement'of' the coupler beinglimited;,byengagement of-the end abutment faces 33 of the arms 23 0f the coupler-shank with, the side faces 31 of the post'29of the. pressure-trans} mitting blockB, as hereinbefo-re pointed out; When a draftaction is applied to the coupler, Y

the yoke l'l is pulled forwardlyithrough.the

medium of the key O, thereby compressing the shock absorbing means which is disposed within the yoke, against the front follower slot 35 of the block is wider than the key to permit of the swinging movement of the key. In a buffing action, the coupler is forced inwardly, thereby forcing the'pressure-transmitting block B inwardly also against the front follower 18, the follower 18 acting with the coupler shank and acts to center the coupler through the pulling action of the' yoke.

Referring next to the embodiment of the invention illustrated in Figure 3, the same comprises, broadly, a coupler D, a pressuretransmitting block E swiveled thereto, and a coupler key F. The coupler key F is connected to a yoke in the same manner as the coupler key C illustrated in Figures 1 and 2, and the pressure-transmitting block E bears directly on the flat front face of a follower block similar to the follower block 18 hereinbefore described.

The' butt end of the coupler shank D is provided with a cylindrical enlargement 40 having a central pocket 41 which is open at the top and provided with a bottom wall 42. The vertical wall of the pocket 41 is of true circular form and the pocket is adapted to receive a cylindrical enlargement 43 formed ion the post section 44 projecting from the pressure-transmitting block E. As clearly shown in Figure 3, the central portion of the, cylindrical enlargement at the rear end of the coupler shank is cut away, as indicated at 45, to accommodate the post section 44. The cut away section 45 is considerably greater than the width of the post, thereby providing flat abutment faces 4646 spaced from the sides of the post. The abutment faces 46 limit the radial swinging movement'of the couplerin the same manner as the corresponding abutyoke member and a front follower co-operating therewith, the combination with a-coument faces at the inner ends of the arms 23 of the coupler A, hereinbefore described; The cylindrical bearing element 43 substan- 'tially fits the pocket 41 so that the coupler D is accurately guided in its swinging movement. The

bearing elements

43 and 40 of the pressure-transmitting block and the coupler shank are held assembled in a similar manner to the corersponding parts hereinbefore described in connection with the embodiment of the invention illustrated in Figures land 2,

ends accommodated in the usual key receiving slots of the yoke and center or draft sills.

As shown in Figure 3, the key receiving slot of the pressure-transmitting block also extends into the post 44 and the front end portion of the block E proper.

In assembling the parts of the swiveled connection as illustrated in Figure 3, the bearing member 43 is inserted through the top of the pocket of the coupler shankand forced downwardly within said pocket until the bearing member 43 rests on the bottom wall of the pocket, and the key receiving slots of the bearing member 43 andthe coupler shank are brought into alignment. The coupler key is then inserted through the aligned 1 key receiving openings of the bearing members, the yoke arms and the draft sills.
