LADDER;

SPECIFICATION forming part of Letters Patent N 0. 714,7 53, dated December 2, 1902.

Application filed April 9, 1902. Serial No. 102.123. (No'inodel.)

To a/ZZ whom t may concern:

Be it known that I, WILLIAM G. SITEMAN, a citizen of the United States, residing at Willianistown Station, in the county of Berkshire and State of Massachusetts, have invented a new and useful Ladder, of which the following is a specification.

This invention is an improved construction of ladder adapted for use in connection with railway-cars, the object being to provide a ladder which shall be safer than those now in common use.

With this object in View the invention consists in the novel features of construction and combination, all of which will be fully described hereinafter and pointed out in the claims.

In the drawings forming a part of this speciication, Figure l is a perspective view illustrating the practical application of my invention, and Fig. 2 is a detail sectional View.

In carrying out my invention I employ two flat metallic bars A and B, the bar A being longer than the bar B and being bent horizontally at its upper end, as shown at A', and secured to the top of the car. The main portion of the bar A is parallel with the end of p the car and extends a short distance in ad- Vance of the said front end. Adjacent to the lower endthe bar is bent inwardly, as shown at A2, and is fastened to the sill of the car at A3, and below the sill the bar is bent to form a step A4, and its extreme end A5is securely fastened to the side of the car. The barB is bent horizontally at its upper end, as shown at B', and fastened to the roof of the car and at its lower end is bent inwardly, as shown at B2", and fastened to the sill of the car, as shown at B3.

The bars A and B are connected by means of a series of steps or rounds C, and the ladder is braced at various points by means of the horizontal brace-bars D, secured to the side of the car and projecting beyond the forward end, the forward ends of' said bars being connected to the bar A, as most clearly shown in Fig. l.

A suitable handle E connects the horizontal portions A and B of the ladder, fastened to the top of the car, and provides a suitable handheld upon the top of the car.

A ladder constructed in this manner is exceedingly strong and not at all liable to pull away from the car, as it wi ll be readily seen that there is no direct pull upon any of the bolts fastening the bars to the car and that the ladder herein provided is safer than those generally employed and equally if not more convenient.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

l. A ladder for railway-cars consisting of the parallel bars, both of which are secured to the roof of the car at their upper ends, one of the bars being continued below the sill of the car, and bent into a step, and the crossbars or steps connecting the parallel bars, substantially as specified.

2. A ladder for railway-cars, consisting of two parallel bars bent horizontally at their upper ends and attached to the roof of the car, both bars being bent inwardly adjacent to their lower ends and secured to the sill of the car, the outer bar being projected below the sill of the car and bent to form a step, and the connecting steps or rounds, all arranged and adapted to operate substantially as described.

VILLIAM G. SITEMAN.
