l 3 i l RAILWAY-GAR LADDER.

To all whom it may concern:

Be it known that I, WILLIAM ERASTUs IVILLIAMs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Railway-Car Ladders, of which the following is a specification.

The general object of this invention is to provide a car ladder that shall be unusually strong, light, durable, low in cost, and unlikely to injure those who use it.

In the drawings, Figurel is a perspective view of my devices applied to a car. Fig. 2 is a plan view of a step seen in Fig. 1. Figs. 3, i are, respectively, an elevation and a vertical section of a similar ladder body used with an ordinary step. a

In these views, 1 represents a car body provided near one corner with integrally connected end and side ladders. Each of these ladders has on each side a pair of side or stile rods 2 lying in a plane perpendicular to the car wall and held in place at some distance from the latter by rung rods 8, 4 passing between the rods of each pair and electrically welded to both. The rungs 4 are bonttoward the car at 5, just without the body of the ladder and are provided with terminal eyes 6 adapting them to be bolted to the car, and as it is desirable to have the stiles held very securely near the edge of the car roof and undesirable to use a rung at this point, a short rod 9 is welded to each side or stile of the ladder, carried back to the car wall, and there fixed by a bolt. The rods forming each stile are bent inward in the plane of the pair just above the margin of the roof and carried for some distance along the surface of the latter, the rods of the side ladder being welded to an interposed rung 8, similar to the rungs 4 and preferably secured to the roof as at 14. The inwardly bent stiles of the end ladder meet and are integrally connected to the nearer stile of the side ladder, whereby each strongly aids in preventing its companion ladder from being torn from the car, and at the same time the four stiles and the rung 8 afiord many variously disposed hand holds some of which may probably be caught in case a sudden lurch should cause either right or left hand to be even instinctively thrown out to seek support.

Each ladder preferably has its stile rods extended below the car the rods on one side Specification of Letters Patent.

being integrally connected with the corresponding rods of the other side, the projectlng parts and their connections forming two stirrups in the same horizontal plane. Between the two connecting portions 10 and in the same plane is placed the lower member of a third stirrup 11 the branches of which have terminal eyes to be bolted to the lower wall or sill of the car, as seen at 12. The three lower members just described are all welded to filler pieces 13, thus forming a strong and rigid ladder step below the car body. This step may be omitted if desired for any reason, and in that case, the common single rod stirrup step being used, the lower part of the ladder would appear as in Figs. 3, 4, a rung at being used as the lower rung of the ladder and secured to the car in the manner before indicated.

The fastening securing the ladders to the roof may be omitted, with some loss of strength, of course; but the factor of safety will remain unusually large.

What I claim is:

1. In a car ladder, the combination with two stile members each consisting of two slightly separated parallel rods, of a series of rungs passing between the rods of each stile, welded to both, bent inwardly at the sides of the ladder to form legs, and provided with terminal eyes to be bolted to a car.

2. In a car ladder, the combination with two stile members each consisting of two parallel rods in a plane perpendicular to the plane of the ladder, bent in that plane near their upper ends to extend for some distance along a car roof, of a series of rungs passing between and welded to the rods of both stiles, bent inwardly at the sides of the ladder to form short legs, and provided with terminal eyes adapting them to be bolted to the car.

3. The combination with a car, of a side ladder hming its stiles formed of parallel rods all integrally connected by rungs and bent to extend inwardly along the car roof, and a second similar ladder adapted to be fixed to the end of the car and having its stile rods rigidly connected with those of the first ladder above the roof of the car.

4. In a car ladder, the combination with stiles each consisting of two rods in the same plane integrally united at intervals by rungs and each rod at its lower end being connected to its companion in the other stile by an integral rocl section parallel to the rungs scribed my name in the presence of two subof a stlrrup lnterposed between szud. rod secscrlblng Witnesses, on tlns 23rd clay of Autlons and havlng branches adapted to be se' gust 1913.
