Jan. 7, 1930. E. EHLERS FIRE ESCAPE RAILING STRUCTURE Filed NOV. 19, 1927 INVENTOR Eda/(pm; Ek/ezx',

BY 3 *2 ATTORNEY Patented Jan. 7, 1933 EDWARD EHLERS, OF MONTCLAIR, NEW JERSEY FIRE-ESCAPE RAILING STRUCTURE Application filed November 19, 1927. Serial No. 234,311.

The present invention relates, generally, to railing structures for fire escapes and the like, and, more particularly, to standards used in making up such railings.

An object of the invention is to provide a standard for metal railings in whichthe use of rivets for fastening the standards to railing stringers is obviated.

Another object of the invention is to pro vide a railing standard which has a riveting element formed unitary therewith.

Other objects of the invention will be clear from the foregoing specification and drawings forming part thereof and from the statements in the appended claims; and the in vention also consists in the new and useful structures and combinations and arrangements of parts set forth in the claims.

In the accompanying drawings, used to iilustrate the invention:

Figures 1 and 2 are respectively face and side elevation views of a railing standard involving the invention;

Figure 3 is a perspective view ofa fire escape railing made up with the standards of Figures 1 and 2;

Figure 4; is a face elevation view of an alternate form of railing standard end; and Figure 5 is an elevation view in part of a railing stringer and a standard of the form shown in Figure t assembled as in a railing. In each of the hereinabove described views, similar reference characters are used to indicate corresponding parts throughout.

Referring now to the drawing, the reference character 1 indicates a railing standard made of iron or steel, wrought, forged or otherwise formed with the flattened ends 2, 2 which have formed unitary therewith the fas tening studs3, 3. These said fastening studs 3, 3 are shown in Figure 3 as having been inserted through openings in the railing stringers 4 and riveted thereto to form therewith a railing structure which is cheap to manufacture and which is strong and secure.

In Figures/1 and 5 are illustrated an alternate embodiment of the invention in which the standard 10 has the flatend 11 forged with the unitary fastening stud 12 which is square and which can be otherwise angular in cross section. In Figure 5 is shown the railing stringer 14 which has punched therein square holes 15 adapted to receive fastening studs 12 of similar shape which are hammered over or riveted in place thereon. In

this way is formed a railing structure which is light and economical and which is strong and rigid and, through the engagement of the square studs 12 in the square holes 15, is safe and firm against sagging or collapse of the railing on itself either partly or wholly.

I am aware that some changes may be made in the varlous arrangements and comblnations of parts ma king up the present in- I claim 1. A ralling for comprising metal fire escapes and the like, stringers havlng spaced apart holes therein, and railing standards having unitary see right angles to the longitudinal axes of said uring studs projecting at standards and positioned in said holes and riveted in place thereon.

2. A railing for fire escapes and the like,

comprising metal stringers having spaced apart angular holes therem, and raihng standards having flattened ends with integral fastening studs ext ending therefrom at right angles to the length of said standards, said studs having the s ame cross sectional shape and size as said holes and being entered thereinto and riveted in place on said stringers.

In testimony, that I claim the invention set forth above I have hereunto set my hand this 14th day of N ovember, 1927. EDWARD EHLERS.
