It is desirable that the striking casting be cast integral, as otherwise the fastening or holding means are likely to become loosened, lost or broken, and, as a result, the coupler bar will not be properly supported.

With the advent of the swivel butt on the cou- .pler bar, great difficulty has been experienced .knuckleon one-end of the bar and the enlarged swivel. mechanism on the other.

ing the same.

.The present invention seeks to" eliminate these difficulties and provide an integral striking plate or casting provided with a coupler support interlocked therewith that may be removedfor inserting'the coupler bar through the striking casting after which the support may be placed in position.

Referringv now to the drawings, the reference character Ill designates a railway car and H the coupler support attached thereto.

'The coupler support comprises the striking casting l2 which is castin one piecehaving the bufierland attaching portion [3 and the lower or coupler supporting portion II with an opening through the same for receiving the .draw'bar l6, as is usual in such constructions.

'The striking casting I2 is provided with'front and rear walls I 9 and 2| (see'FigB), which are connected together by a suitable means such as the ribs and 22 and by bottom wall .23. The

bottom wall slopes toward the vertical centerlineof the casting, asshown inFig. 1 and has an opening 24 through which water and dust that may collect in the casting mayescape. 7

Attached to each of the walls l9 and'Zl adjacent the bottom wall '23 at one side of the opening E lis, apair of concave ledges forming tracks 25 and a s'imilar'lpair of concave tracks 26 are located at the other side of the opening 24. These \tracks are arranged in a horizontal plane. The

tracks of each pair are arranged in spaced relation to provide an opening2T between thetracks of each pair through'which water, dirt and other foreign matter may escape from the tracks.

The draw bar 'I 6, shown in dotted lines in Fig. 3, may 'be of the usual or any well known construction and comprises the coupler head 28, the

' body portion 29v and the couplerbutt 3| which is porting the draw bar I'G within the opening l5.

In the form of the invention disclosed inFigs. 1 to 6, inclusive, which is by way of example only, this means comprises mechanism for automatically centering'the draw bar as well as supportmechan'ism comprises a cradle member 33(see Fig. 6), and a suitable carryingiron as will presently appear. The cradle L33. comprises the body portion 34 having on its underside concave recesses 35 and '36 which form tracksadapted to cooperate with the tracks 25 and .26 for receivvided with a horizontal slot orgroove 42 extend- "ing across the same adjacent to the body portion and, with a verticalslot or recess 43 extending downwardly alongthe center-line of theaarm v In the construction shown, this from the slot 42. Each arm is also provided with a recess 44 adjacent the upper end at its central portion. The arms are preferably, though not necessarily, provided with lateral extensions 45 and 46 which are adapted to engage the side walls l9 and 2| during the operation of the device for preventing the accidental removal either forwardly or backwardly of the cradle from the striking casting l2.

In order that the draw bar l6 may be removed without removing the cradle 33, a suitable detachable carrying iron 41 (see Fig. 4) is provided. This member may also be a hollow casting having a sand-relief opening 48 in the lower portion thereof so that water falling therein may escape. The carrying iron is provided at each end with lugs 49 and which are adapted to seat in the recesses 43 and 44 when the parts are assembled. The carrying iron 41 may be assembled on the cradle 33 from either side by causing the lugs 49 to enter the slots 42 and forcing the same inwardly until the lugs 49 and 5| drop into the recesses 43 and 44. The upper edge of the carrying iron 41 is provided at each end thereof with upstanding lugs 52 between which the draw bar [6 is adapted to extend. The lugs 52 will cause the carrying iron to move with the draw bar when the same moves laterally.

The lugs 52 are of such height that when the parts are assembled and the cradle 33 is moved laterally they will engage beneath the inner ribs 22 for limiting the further movement of the cradle.

The parts are so constructed that the cradle 33 may be inserted in the striking casting between the ribs 22 and the tracks 25 and 26 by first removing the carrying iron 33. After the cradle is in position, the carrying iron 33 may be readily placed in position.

Under ordinary operating conditions the carrying iron will be held in operative position in the cradle by gravity without additional securing means. If desired, however, means may be provided for holding the carrying iron in position in any emergency. Any suitable means may be employed for this purpose. In the form of construction shown, a lock bar 53 is employed for this purpose. It is rigidly secured to the projection 45 of the cradle and has its inner end engaging in a slot 54 in the adjacent lug 52. When it is desired to insert or remove a draw bar of the type shown in Fig. 3, the lock bar 53 is removed, the carrying iron is raised sufiiciently to bring the lugs 49 in alignment with the slots 42 after which the carrying iron is moved either forwardly or rearwardly which disengages the same from the cradle 33.

The carrying iron is of such dimensions that the additional space provided by the removal of the carrying iron will be sufficient to permit the removal of the draw bar from the striking cast- In the operation of the device, when the draw bar is moved laterally, the rollers 31 and 38 will travel along the concave tracks and constitute roller bearings. These tracks are elongated for permitting lateral movement, and, as a result of the roller bearings, the draw bar may be readily moved to either side but due to the concavity of the tracks, the bar will be elevated when moved in either direction and its weight will restore it to its normal central position where the bar is uncoupled from another car.

A modified form of the device is shown in Figs. 7, 8 and 9. In this form of construction, the centering device is eliminated, only the carrying iron being employed. As shown, the striking casting 55 is cast in an integral structure, as in the previous construction and may be provided with suitable reinforcing ribs 56, if desired. The marginal walls .of the opening 51 are extended inwardly at their lower portions to form the offsets 60 and each is provided with a horizontal slot 58 and vertical recesses 59 corresponding to the horizontal slot 42 and recess 43 of the cradle 33 in the construction described above. A vertical recess 6| is also provided in the upper portion of each offset 60 which corresponds to the recesses 44in the cradle 33.

In the form of construction shown, the carrying iron 62 is provided at each end thereof with an upper lug 63 and a lower lug 64 for seating in the recesses 59 and 6 I, as in the previous construction.

The carrying iron may be held by gravity alone or positively held from vertical movement by any suitable means. As shown, a hole may be drilled partly in the end of the carrying iron and partly in the offset portion 6|] and. a rivet 65 inserted in this opening, as shown in Figs. 7 and 8.

When it is desired to remove the draw bar Hi, the rivet 65 is removed, after which the carrying iron may be elevated and moved laterally for removing the same from the casting 55, after which the draw bar may be removed through the enlarged opening 51.

It will thus be seen that with either form of the device, the striking casting is an integral structure and is cast in a single piece with the draw bar opening therethrough, thus eliminating the necessity of using bolts or the like for securing the parts together with the attending danger of the bolts becoming accidentally or surreptitiously removed.

The carrying iron being interlocked with the striking casting in such a manner that the weight of the same and the weight of the draw bar assists in holding the parts in assembled relation renders the use of bolts, rivets or other detachable fastening means unnecessary except as precautionary measures. These features are considered important.

It is thought from the foregoing taken in connection with the accompanying drawings that the construction and operation of my device will be apparent to those skilled in the art and that changes in size, shape, proportion and details of construction may be made without departing from the spirit and scope of the appended claims.
