While I have shownmy invention as apders for railroad cars and has for its object the plied to a round corner car, it is, of course, undermounting on a car of a stileless ladder, the rungs stood that it may be applied with equal eiiiciency of which extend from the side wall of the car to a square cornered car.

This stileless ladder embodying my invention is built directly on the car.

While I have herein shown and described what I now consider the proper manner of carrying out my invention, the same is merely illustrative and I contemplate all changes and modifications that may come within the scope of the claims appended hereto. s

By the term no obstruction in the rungs from end to end I mean that there is no vertical ladder stile over which a train operator must climb in passing from a side ladderto an end ladder. When the operator is holding on to a ladder with one hand and standing on one of the lower rungs the spacing member 9 functions as stated as a protection to brace his foot against slipping and to assist him in maintaining his position on the ladder when the train is in motion,

By means of my improved end and side wal?. ladder the operator may mount the rungs of the side of the car and work around to the rungs on the end of the car orrvice versa.

In the conventional arrangement of freight car ladders the brakeman must step from the side ladder to thetend wall ladder because of the distinct separation of the two. Having a separate ladder rung on ythe side of the car and a separate rung on the end ladder, in instances where they are not on the same plane, the brakeman does not have the safety of my improved integral side and end wall rungs, which maintains the same level at both theside and end wall of the car.

Inv Figure 5 I have illustrated the application of my stileless ladder to'a car having square or rectangular corners. In this view the car is designated by the reference numeral I4. The

Y rungs I5 are of a rectangular shape following the contour of the car corners and have inwardly extending ends corresponding to theends 5 of the rungs 4 which are secured, respectively, to the side and end walls of the car.V AThe intermediate spacing member I8 is secured at the corner of the car and functions like the spacing member.

What I claim is:

1. The combination with a raliroad car having an end wall, a side wall and a corner at the junc ture of said walls, of a stileless ladder consisting solely of a plurality of rungs, spaced an equal distance throughout their length from the end, corner and side walls of the car, one end of each rung having an integral spacing arm secured to the end wall ofthe car and the` Aotheiend of each rung having Aan integral spacing arm secured to the side wall of the car, and an inclined individual support for each rung having an inner end portion secured to the corner walll above the level of the rung and extending outwardly and downwardly at an angle therefrom and having an outer end portion engaging the rung intermediate the ends of the rung, whereby each rung is supported free from connection with any `other rung and whereby each individual rung support forms a foot brace against which the foot of a trainman standing on the rung may be brought to bear to assist the trainman in maintaining Yhis position on the `ladder when the car is in motion.

2. The combination with a railway car having a side `wa1lan end wall,` and a corner portion connecting said walls, of a stileless ladder consisting solely of a plurality of individual rungs spaced yan equal distance throughout their length from the corner portion and side and end Walls of the car, one end of each rung beingr secured to the side wall of the car and the other end thereof to the end wall of the car, and an individual support for each rung located mainly above the level of the rung and having an upper end portion secured to the corner portion of the car and thence bent outwardly and downwardly therefrom andhavingalower end engaging the center of the rung, whereby each rung is supported from the car free from connection with any other rung and whereby each individual rung support forms a foot brace against which the foot of a trainman standing on the rung may be brought to bear to assist the trainman in maintaining his position on the ladder when the car is in motion.
