WILLIAM EVWINE, or WILMINGTON, vNonnen CAROLINA, AssIGNoR RAILWAY APPLIANCE COMPANY, A

TO THE WINE CORPORATION 0F OHIO.

LADDER.

may concern.: j that I, `W1LLIAM E. XVINE, a citizen of' the United States, residing` at Wilmington, in the county of New Hanover and State of North Carolina, have invented new and useful Improvements in Ladders, of whichv the following is a specification, refer.- ence being had to theaccompanying drawings. forming a part hereof.

My invention relates to ladders in general but more especially to those used on freight cars.

Ladders in general use on freight cars comprise stilcs of wood or met-al to which t ie rungs are bolted or riveted. or the rungs are bolted direct to the car. Where Wooden stiles are used and where the rungs are bolted direct to the car the bolts frequently work loose caused by shrinkage of the wood and vibrations ot' the car body. Where the ruiigs are riveted to or upset intoinetal stiles the expense of construct-ion becomes quite an iteni. 'l

Therefore the object of my invention is to so construct the stiles and rungs of a ladder that they may be assembled without the use of either bolts or rivets.

A further object of my inventi n is to produce'a ladder that will not fall apart or the rungs become disconnected from the stiles To all 107mm it Be it known in case ot' accident to the c'ar.

A further object of my invention is to produce a Aladder which can be built and applied :it a minimum cost.

iV ith these and other objects hereinafter explained in view my invention consists in the construction and combination -ot `ele incnts hereinafter described and claimed.A

ln the accompanying drawings which'illustrate the vcntion: Figure l is a side elevation of a poi-tion of a car showing ladders applied to both the side and end of a car. Fig. 2 is an end elevation of saine. Fig. 3 is a section ot the ladder online 3-3.l

angle iron ladder Stiles are denoted by l which are provided with two rows ol." holes 2 and 2 substantially at right angles into which are inserted the specially formed run'gs 4 are angle iron brackets for bolting the ladder to the car and are secured to the' stiles by rivets 5. In Fig. 3 is shown the. preferred form of rung but-it is obvious that a number of shapes for the end of the rungs can be made to fulfil the requirements, some of which are shown in Figs. 4; and 5 In F ig. 6 is shown a tubular and 2a in relatively the same position as those shown in Fig. Vith this form 'of stile the ladder is held to the car body by brackets G. It will also be noted that all forms of rangs applicable to the ang-le iron stile are equally applicable to Patentedoct. 1,1912.

Stile l? with the car by stile and is spaced from In order to apply rungs to the stiles or the Stiles to the rungs the ends of the rungs are inserted in holes 2 and the rungs or Stiles revolved through an anfrle of ninety degrees until the ends of the rungs project through holes 2, into the position shown in the 4various figures of the drawings.'

Instead of angle irons any of the standard rolled sections may be used namely, :chaniiels, Zs` Ts, etc.

.It will be understood from this description that although the improvements of this invention are simple they accomplish in a thoroughly-practical manner all the objects .sought and that by their employment danger ot accidents hitherto arising` from detached run'gs isv prevented. Furthermore repairs may readily be made and the separation of the rungs from the Stiles bel positively prevente so long as the ladder reinainsbolted to the car. It Will of course be understood that I do not desire to be limited to the specific con'- struc'tion or arrangement of elements shown is obvious that changes and described, as 1t in construction and arrangementv may be made Without departing .from the spirit of the invention ayingthus described my invention7 I 1n the appended claims to cover all not involve a departure from its spirit and-Scope.

What I claiml as new and desire to secure by Letters Patent of the United States, is:

1. A ladder' having stiles Whose cross section provides divergent wall portions and having holes through such Wall portions, the axes of Which holes are at an angle to each other and rungs engaged i' the holes.

2. In a ladder, angle bar stiles, eaeh stile provided with holes in each lange and ar ranged in pairs, each pair comprising one hole in each flange and rungs with their ends each engaged in a pair of holes.

3. In a ladder, comprising stiles and detachable rungs, each stile provided With two series of holes With their axes at an angleto each other and arranged in pairs, each p pair consisting of one hole 1n each series, each rung having offset ends engaged in dhe pair of holes in each stile.-

4. In a ladder, comprising stiles provided with tWo series-of holes with their axes at an angleto each other and arranged in pairs, each pair consisting of one hole in each series and rangs each having ends turned at an angle to the main portion and engaged in one pair of holes in each stile.

5. A ladder having stiles whose cross seotion provides divergent Wall portions and/ having holes through such Wall portions, the axes of which holes are at an angle to each other and rungs having ends deflected from the line of lout parallel with the main portion and engaged in the holes.

This specification signed and witnessed this first day of November 1911.
