struction is used it must be retained by a nut or cotter or other similar means, which become loose or lost, thus making it possible for the link to become disengaged from either the car part orthe carrier.

My device is an improvement upon such structures and comprises means to retain one or both of the links in operativeposition, that is, to retain the trunnions in their-proper bearings which means are actuated and retained in their normal position by gravity alone and which may be easily moved 'out' of the normal position to permit the removal of the T-head from its hearing, which means ,are preferably permanently attached to a part of the car.

In the drawings:

Fig. 1 shows a plan View on the right half of the center line and on the left hand of the center line a section on line 1-1 of Fig. 2'.

Fig. 2 shows a typical application of my device to a railway car.

Fig. 3 is a section on line 33 of Fig. 1.

Figs. 4 and 5 show fragmentary portions of the car part, link and retainer.

Fig. 6 is a perspective view of the retainer shown in Figs. 4 and 5.

Figs. 7 and 8 are fragmentary portions of the car part, link and modified retainer.

Fig. 9 is a perspective view of the link shown in Figs. 7 and 8.

In the form illustrated the carrier 2 is swingably suspended from the striking casting (or car part 3) by links 4 at its opposite ends, which links are provided with T-heads or trunnions 5 at each opposite end which engage hearings in a carrier and car part, respectively. d

bearings while the coupler is in position upon If the journals for the trun the I carrier. nions are made less than it is possible for the trunnions to jump 'outof the bearings due to impacts of the cars in service, particularly when being coupled, and if the vertical depth ofthe bearing is made greater than the said 1 then the trunnions cannot be removed from the bearings while the coupler is in operative position on the carrier.

It is sometimes desirable to remove the carrier 2 or one of the links 4 while the coupler is in position upon the carrier, therefore, it is necessary to make the bearing (10) of at least one of the upper trunnions of less vertical dimension than the permissible vertical movement of the coupler (6), in which case some means must be provided to retain the trunnion in its bearing.

In my construction I provide such a means by retainer 11 having an elongated slot 12 therein which engages a pintle13 permanently secured to the striking casting or other part of the car. When in normal position, which it assumes by gravity, the lower end of this retainer is adjacent the trunnion 5 so as toretain it in its bearing but with the pintle and slot arrangement it is capable of being moved in a vertical direction to permit the removal of the link from its bearing. The pintle 13 is provided with a head 16 and the lower portion of the retainer engages a recess 17 in the car part so that the head and the recess jointly and severally prevent the retainer from swinging in a plane laterally of the car. The retainer is of such width that it can not swing longitudinally of the car to an extent which would permit the removal coupler shank, by the A. R. A., therebearing a tool is placed within the slot 20 under the retainer and the retainer is moved vertically out of the way.

Figs. 7, 8 and 9 show a modified construction wherein the pivot 30 of the retainer is sitioned normal to the constructon shown in Figs. 4, and 6. The lip 31 on the retainer 32 prevents it from swinging out of vertical line. 10 The accompanying drawings illustrate the referred form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof within the scope of the claim will occur to persons skilled in the art.

I claim: The combination in a railway car of a car part, a carrier swingably suspended therefrom by links, one of said links having a jourml at its upper end engaging a bearing in the car part, a retainer secured to the car art so as to normally retain thejournal in its bearing, said retainer having a slot therein engaging a pintle on the car part whereby vertical movement of the retainer is permitted, and means to prevent the retainer from swinging in: any direction.
