HARRY H. sonnovna, or CHICAGO, ILLINOIS, ASSIGNOR TO THE ACME SUPPLY COMPANY, A. CORPORATION or ILLINOIS.-

LADDER FOR CARS.

To all whom it may concern Be it known that I, HARRY H. SoHRoYER, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Ladders for Cars; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numbers of reference marked thereon, which form a part of this specification.

Accidents have frequentlyhappened owing to the failure of the grab irons or the ladders or some part thereof, attached to the car end, which, giving away under the weight of the operator, permitshim to fall beneath the car. This has frequently been occasioned from the manner of construction of the ladder at the side or end of the car, which usually is constructed of separate bars or rods bent to the proper form and secured in place by means of lag screws passing through the ends thereof and into the wood of the car side or frame.

The object of this invention is to afiord a ladder in which the individual rounds are secured upon suitable stiles and the ladder as a whole attached to the car side or end by means of bolts, which act to rigidly engage the same in place.

It is also an object of the invention to afford an exceedingly cheap, and simple construction, adapted to be knocked down for shipment, and permitting quick assembling and installation.

It is further an object of the invention to afford in connection with a ladder such as described, a reinforcement for that portion of the stiles extending below the car bottom to support the lower round or step and as a whole to afford an exceedingly strong, durable and safe construction.

The invention in its preferred form, is hereinafter more fully illustrated and described.

In the drawingszFigure 1 is a fragmentary end elevation of a car equipped with a ladder embodying my invention, showing the ladder applied on one side and one end thereof at the corner. Fig. 2 is an enlarged fragmentary transverse section of the installation illustrated in Fig. 1, showing the attaching bolts in elevation. Fig. 3 is an end elevation of one of the rounds or steps Specification of Letters Patent.

before insertion into the stile. Fig. 4 is a side elevation broken away, of one of the stiles, with the flanges cut away between the rounds. Fig. 5 is an enlarged fragmentary front elevation of the lower portion of the ladder. Fig. 6 is a rear elevation thereof. Fig. 7 is a bottom plan view of one of the rounds, showing the stiles in section, and illustrating the method of securing the rounds in the stiles. Fig. 8 is an enlarged detail similar to Fig. 7, and showing the round and one stile broken away. Fig. 9 is an enlarged fragmentary rear elevation showing the upper end of one of the stiles and the end of the round attached thereto.

As shown in the drawings: 1, indicates the car end; 2, the corner frame post within the car; 3, the outer covering or car side and end; and 4, the longitudinal block or reinforcing strip secured on the inner side of the car opposite the point of attachment of the ladder thereto.

5, 6, and 7 indicate the stiles for the ladder, in this instance shown as three in number, inasmuch as the ladder is illustrated attached to the car side and end at one corner thereof to afford a side ladder and an end ladder. Of course, where attached to the side or to the end only, but two stiles are required.

The stiles, as shown, each comprise a deep, narrow rolled channel having a web 8, and lateral flanges 9, which extend substantially parallel for a distance corresponding with, or slightly greater than the thickness of the round and thence diverge bracingly, as shown in Figs. 2, 7, and 8, and are provided at the upper and the lower end thereof with outwardly directed foot flanges 10, which are apertured to receive the bolts 11, whereby the stiles are attached in place. The foot flanges for the side and end stiles are, of course, turned outwardly in the same plane while the foot flanges 12, for the center or corner stile 7, are turned at an angle of 90 degrees with reference to each :ot-her to engage the corner of the car.

As shown, a bottom guard plate 13, is secured by spot welding or other suitable means, to the foot flanges of said stiles, serving to rigidly tie the same together at the bottom and at the top and acting to sustain in part, the thrust occasioned by an operator when boarding a moving car.

Each of the tiles 5 and 6, as shown in Figs. 2 and 4, is provided with an aperture the ladder is secured both on the end and,

side, as shown in Figs. 1 and 2, is provided with apertures through both flanges, tho e-c in each flange being arranged at the samev height as the aperture in the adjacent side tile, said apertures being arranged, however, in the corner stile to break joints, as illustrated in Fig. 2, and as shown in dotted lines in Fig. 1. The rounds 1 L, alsoof pressed steel, are shown as tubular, and are rolled to afford a continuous top and sides with the edges of the strip from which the round is constructed, brought together or meeting on the under side thereof.

The ladder is assembled by inserting the ends of the rounds through the apertures in the sides of the stiles, and then inserting a suitable tool of any kind and flaring the ends of the round, as illustrated in Figs. 7, 8, and 9, thereby so enlarging the same as to preclude the withdrawal thereof from the stiles. As shown in Fig. 3, the end of the round is shaped to fit accurately in the complemental aperture therefor in the stile.

Of course, if it should be desired, the foot flanges may extend for the entire length of the stile. Ordinarily, however, this is neither necessary nor desirable, inasmuch as the stiles are exceedingly strong and rigid, being rolled of a sufiiciently heavy gage of metal to serve the purpose. If the flanges of the stiles are cut away, as illustrated in Fig. 4, intermediate the foot flanges, at the upper and lower end thereof, a lighter structure is afiorded and one that permits the operator to engage the stile with his hand as well as the round, should it ever be necessary.

Of course, it is to be understood that de-.

I claim as my invention: 1. A device of the class described embracing channeled stile members, integral legs extending therefrom at each end there i H of, bearing feet on said legs and integral 1 'andja plurality of rungs connectedinto each therewith adapted for attachment to a car,

of said channeled stile members. i

is In a device of the class described Chan- 7 ,neled stile members having apertures therein, a plurality of; tubular rungs having a longitudinal slot onthe under side thereof and the ends of said rungs extending into said apertures in the stiles and the corners thereof flangedover to rigidly engage the '65 3.
