' Specification of Letters Patent.

" nTALLIc SIDING.

Application filed January 30, 1909. Serial No. 475,122.

To all tvhom it mat "concern: Be it known that LWILHELM' F. Bonnnss, a citizen of the United States, and residing in Chicago, in the-county of Cook and State of Illinois, have invented a new and useful Improvement in Metallic Siding, of which n the following isa complete specification.

t employed.

This invention relates to improvements in metallic siding and more particularlyto mef tallic siding for railway cars, tho'ughxobvi ou'sly it is equally well ada ted for'n'se'upon outer surface of which the metallic siding 'had been applied. Such siding has usually been constructed in largesheets, and for the purpose of strengthening the same and affording the desired finish it has been proyided with deep grooves or corrugations in which have been secured wooden strips or stays. Such construction is more or lessobjectionable, owing to the expansion and contraction of the metal due to changes in temperatures, which causes the wooden strips to become loosened and to rattle when the car is in motion.

The object of, this invention is to provide 7 a metallic siding especially adapted for use on railway cars, the st-rlps of which are adapted to be secured together by a lock seam or joint, which not only affords the desired rigidity and prevents rattling, but also provides a very "neat exterior finish:

A further object of the invention, is to provide a metallic-*siding so constructed as toprovide air spaces between the same and the outer sheathing of the car, and in which the joints between adjacent'st-rips are insured of a tight fit by reason of the resiliency of the metal.

\ The invention consists of the matters hereinafter described in the specification, and more fully pointed out and defined in the appended claims.

In the drawings, Figure lis a fragmentary, horizontal section ofia' car body provided with siding embodying my invention. Fig. 2 is a fragmentary, perspective view of a strip of siding embodying my invention.

As shown in said drawings: A-A indicate the posts or other upright members of a car frame, and which, as herein shown, are

constructed-of beams, and are secured together by means of braces or girders a. On

comprises a bead cl any preferred manner,

The space formed UNIT-ED T OFFICE.

the inner face of said I beams, is secured in the inner sheathing B, and on the outer face thereof, is secured the outer sheathing B, which is preferably constructed of sheet steel.

between the outer and inner sheathings may 4 be filled with any of the usual composition fillings, indicatedby C, which are ordinarilv useddn such structures to'afford a. nonconductor of heat. D On the outer' face of the outer 1s. secured the siding, which is formed in strlps of the desired width, and indicated as a whole by D. Said strips are preferably secured in vertical position upon the car and each comprises a central portion 03, which affords the outer face or finish, and an outer sheathing and an inner looking or joint member, one on each margin thereof. The outer joint member metal back upon the tion cl, with the part said portion left out of contact therewith, and the part inwardly of said margin brought into contact with said portion, as shown at (P. The metal is then turned inwardly toward the sheathing B, as indicated at d for a sufiicient distance to space the portion (Z the required distance from said sheathing, beneath and beyond the bead to provide the attaching flange d Said flange is provided with apertures 0Z through which screws d may be inserted, to secure the strip tothe sheathing, as shown more clearly in Fig. 1. The inner joint member, which is provided inner face of said poron the opposite margin of the portiond, is

formed by turning the metal inwardly to provide a web dfparallel with and corresponding to the web (Z and then laterally in the plane of the flange d, but oppositely therefrom to provide a base portion 01 and then outwardly and laterally toward the web d to provide a tongue d adapted to engage behind said head. The hook thus formed, is adapted to be inserted. in the space formed between the head 01, the portion 03 the web (l and the flange 0?, as shown more clearly in Fig. 1.

In operation, one of the strips of siding is secured to the car body by means of the formed by folding the I beneath the margin of and is then turned laterally 1 screws zilengaging through the apertures (1 and thehook or inner oint memberof the next adjacent strip is then inserted in the space formed behind the bead d, and as the strip is swung into place, the hook is forced into said space where it form a sulficiently tight joint to prevent the siding from becoming loosened by changes in temperature. The structure thus formed aflords a very neat exterior finish, and may be ap plied to other structures as well as car bodies on which it may be desired to place siding material.

Obviously, a siding constructed in accordance with my invention is adapted to not only afford a neat exterior finish, but to obviate all the annoyance caused by rattling as is the case where wooden reinforcing strips have been employed, and obviously, also many details of form and construction may be varied withoutdeparting from the principles of my invention.

I claim as my invention:

1. A metallic siding strip comprising a central face portion, a hollow bead on the inner face thereof adjacent one lateral margin, a reinforcing strip extending from one side of said bead parallel and in close contact with the face portion, a spacing web extending inwardly from one margin of said strip, an attaching flange extending from the inner margin of the web outwardly from beneath the bead and providing a recess between the same and said bead, strip and web, a web extending inwardly from the opposite margin of the face portion, a base extending laterally from the inner v edge thereof, and a hooked portion extendmg upwardly from said base and laterally toward the face portion and adapted tofit' closely behind the bead on the adjacent strip.

2. A. metallic siding strip comprising a sheet of metal folded to provide a central face portion (1, a hollow bead d beneath the margin of sa1d face portion, a reinforcing stripd extending laterally from said head in close contact to the inner side of said face portion, a spacing web d extending inwardly from the margin of said reinforcing strip, a flange d extending laterally from the inner margin of said spacing web .to a point beyond said bead, an inwardly directed web 01 on the opposite margin of said face portion adapted to abut against the bead on the adjoining strip, a base portion 03 adapted to lie flat on the flange J and an outwardly and laterally directed tongue d adapted to lie in close contact with the web 01 and strip d of an adjoining siding strip and abut at its edge against the inner side of the bead on said strip.

In testimony whereof I have hereunto subscribed my name in the presence of two witnesses.
