f WILLIAM WINE, or TOLEDO, voHro CAR LADDER 1 Original application filed April 16, 1928, Serial No. 2705303.Y Divided -and this applicationv led April 17,

1929. Serial My invention relates to new and useful improvements in car ladders, and the pres- ,lolironsothatafter the rungs are placed in position and the stilesset, no further-fasteningfor thefrungs is necessary. e Y

In its broadest aspect it is lsimilar to the* ladder shown in the lpatent granted to me on February 13, 1917, numbered 1,215,455.

The `present invention, however,- contemplates the use of Vtwo bracketsV designed to be fastened to the sides of acar or other structure, andV to secure to the opposite ends of the stiles aform ofbracket which latter are designed to cooperate with the lsaid brackets on the car, so that the ladder as an entirety, may be quickly hung and bolted into place,

or just as quickly removed.

Still another object of the invention is to provide a car ladder that may be easily and quickly fabricated or assembled and wherein the brackets may be quickly applied to a Y -stiles there will be seen ametal angle iron freight car, after which the ladder may be quickly hung and bolted in place so that the cost of installation is greatly reduced.

Still another objectof the invention is to so construct a ladderl which may be quickly and easilyinstalled,that if for any reason .one inthe one face ofthe angle and the other Vhole in the opposite face.

vit should becomeV damaged in service, it is but a simple matter :to remove the` old ladder and replace it with a new one. i

With theseand other objects in view, the `invention consists in certain new and novel arrangements and combination yof parts as will be hereinafter more fully `described and pointed out in the claims.

Referring now to the drawings showing a preferred embodiment of the invention,

Fig. 8 is a perspective View of the bracket Awhlich cooperates with the lower end of the sti e. vReferring more inparticular to the-several views, there is shownv in Fig. 1 the fragmentary end 1 of ahopper car, andsecuredby brackets, (to be hereinafter described) is the ladder'2 which extends from the top of the car down to the side sill 3. Y Y

' There may also be seen a ladder 4 fastened to the end of thecar, whilebeneath the ladder 2 may be seen the usual step 5. It will'also be seenthat the vladder-comprises thetwo stiles -6 and 7 which vare identical, so a description of the one will be a description of the other.

Describing, therefore', in detail one of these which is provided in the present illustration, with-foursets of holes in the -two faces, one hole of each set being opposite the hole of the YIn Fig. 7a set of these holes may beseen,

j In my earlier patent, above referred to, I simplymade. these holes circular in shape,

but I have found that by flattening out the .therung to fit withinthe respectivev holes of the stiles andthe 'way in which I olf-set the rungsfis the subject inatter ofthe parental applicatiomso thatfin this application I will only describe briefly the specific construction of the Vendsof the stile and the manner of securingthemiin position. Y Y

Looking at 3, 4 and 6, it will be seen that the rung 10 is offset, as at the point 11, then llattened, as at 12, and again bent, as at 13. The rung` then projects outwardly, as at 14:. while the front and rear faces are Hattened, as at 15 and 15a.' rlhe face 15a is slightly inclined to the axis of the rung, so that it will clear the flattened side wall 9 when the rung is inserted.

To insert the rung 10 in the stile, it is only necessary to place the end in one face of the angle and move it through the opening until the end 14 passes outwardly through the other opening or hole 9, and in the same manner :s the opposite end of the rung through the t stile, as will be readily understood. By flattening the ends of the rung and making the holes rectangular in shape, it allows me to use a thicker rung without drilling larger holes in the stile.

rllhis part of the invention, as heretofore mentioned, forms the subject matter of the parental application.

Referring now to the gist oi' the invention, that is the manner ot applying the ladders to the cars or other structures, and referring to Figs. 3 to S inclusive, and particularly to Fig. 7, it will be seen that the stile 6 has on one of its faces a torni et bracket 16 which comprises a piece of metal having the one tace 17 which is bent over ou itself to form the face 18 and to also form the space 19 which will receive the end 2O of the car bracket 21 as will be shortly described. This bracket 16 or tongue is riveted as at 2u to the inner face of the stile, and is substantially the width of one of the faces of the stile, so that the inner edge of the bracket will lie Hush with the adjacent face of the stile.

It will be noted, however, that this bracket 16 is also cut away along its inner edge as at 23. which is in the same plane with the lower edge 24 ot the inner face-17 ot the bracket. flust below the rivet 22, there is another hole 25 directly opposite a hole 26 in the tace of the stile so that when the stile is placed in the position as shown in Fig. 3, the end 20 of the bracket will lit within the space 19 and the lip 27 on the end 20 ot the car bracket 21 will t in the cut out portion 23 to thus support and hold the stile, as will be readily understood.

There are two of these car brackets 21, preferably metal strips, and both have their opposite ends bent as just above described. One of these brackets is placed near the upper part of the car and one down by the side sill. It will alsobe understood that there is a bracket 16 on the upper end ot the stile so that when the ladder is placed in position, the four brackets 16 will'fit over the four ends of the two car brackets 21. The bolts 28 will then be passed through the stiles and the brackets 16 and through the bolt holes 29 in the ends 20 of the bracket 21, and thus securely lock the ladder as a whole to the car side or end. The bolts 28 will have square heads and will i'it up against the lips 27 to be thus held against turning when the nuts are applied to the bolts.

rIhus it will be seen that after the brackets 21 are securely riveted lto the car sides or car ends, the ladder being previously assembled, will simply be placed slightly above the bracket and then pulled down into place so that the brackets 16 will also engage the respective ends of the brackets 21, after which the bolts 28 will be tightened into position.

lt at any time it is desired to remove the ladder. the bolts 28 are simply removed and the ladder lifted slightly off the bracket and then bodily removed.

From the foregoing it will be seen that I have provided an extremely eiicient form of ladder wherein the rungs may be quickly slipped within the stiles and after the car brackets are placed in position on the ends and sides of the car, the ladders may be placed in position so that the small brackets on the ends of the stile interlock with the brackets on the car and after which the 'few bolts may be placed in position to rigidly tie the ladder to the car.

rlhe ladder is relatively light in weight, and the many thousands of ladders now in use are proving very efiicient.

Many slight changes might be made withont in any way departing from the spirit and scope oi"- the invention.

Having thus described my invention, what l claim as new and desire to secure by Letters Patent is:

1. A car ladder comprising Stiles and rungs, a bracket secured to the upper and lower ends of said stiles, each of said brackets comprising a member turned back on itself, said turned back portion terminatingl short of the lower end of the front part of the member, the said member having an inner edge cut away in a line flush with the lower edges of the turned back portion of the member, and two cooperating brackets adapted to be fastened to a car and have their ends interlocked within the said brackets on the stiles.

2. ln a car ladder, angle iron stiles, a bracket riveted within the angles, each of said brackets comprising a member turned back on itself, and said turned back portion terminating short of the lower end of the front part of the member, the turned back portion lying flush with a leg of the stile to thereby form a space between the leg of the stile and the outer portion of said bracket, the inner edge of the outer portion of the bracket being cut away to form a notch extending flush with the turned back portion, and said brackets adapted to interlock with a car bracket.
