UNITED STATES PATENT OFFICE.

FRANK G. CALDWELL, OF WHEELING, WEST VIRGINIA.

CONSTRUCTION OF RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 391,296, dated October 16, 1888.

Application filed May 8, 1888. Serial No. 273,250.

To all whom it may concern.-

Be it known that I, FRANK G. CALDWELL, a citizen of the United States, residing at \Vheeling, in the county of Ohio and State of West Virginia, have invented new and useful Improvements in Construction of Railway- Gars, of which the following is aspecification.

My invention relates to iron roofing for railway-cars, and the purpose thereof is to provide an improved construction of the sheathing-boards and a novel and superior method of fastening the sheet-metal sections thereto without nailing to form a perfectly waterproof covering which cannot blow off in heavy gales, which is light and strong, and not injured by passage over the roof.

The invention consists in the several novel features of construction and new combinations of parts, hereinafter fully described, and then definitely pointed out in the claims.

In the accompanying drawings, Figure 1 is an end elevation showing the general outline of the several iron sections of which the roof is made. Fig. 2 is a perspective view of a fractional portion of a car-roof, showing the sheathing-boards and the manner in which they are formed and nailed to the purlin. Fig. 3 is a similar view showing the manner in which the iron is secured to the sheathing.

In the said drawings, the reference-numeral 1 designates the purlin of a car-roof of ordinary construction. Upon this timber the sheathing- boards 2 and 2 are laid, out to suit theroofing, and nailed to the purlin, as shown in Fig. 3. The sheathingboards all have their longer upper edges beveled off at 3, and upon each alternate board or strip, 2, is formed a gain, 4, lying beneath the bevels 3. These sheathing-strips are laid upon the purlin in regular order, with a brief interval between the adjacent boards, and nails 5 are driven through said strips into the purlin. Upon these sheathing-strips are slipped the sections of iron roofing, 6 and 7, the section 6 being placed upon the gained strip 2, while the section 7 is slipped upon the strip 2, which is simply beveled at 3. The section 6 conforms closely to the contour of the gained strip, having inwardlyturned edges 7, which lie in the gains 4. The sections 7 are similarly formed,

save that they have longer inclined sides, 8,

(N0 model.)

then upward and outward, forming the free inclined edges 9. The double horizontal portions 10 beneath these free edges lie in the gains 4 0f the adjacent strips, the free edges 9 lapping over upon the bevels 3, beneath the inclined edges of the section 6, the inwardlyturned edges of the latter lying in the double fold 10.

By this construction the iron sections may be secured without nailing, are wholly waterproof, and entirely secure against displace ment duringagale of wind. The roofing-sections are slipped into place from each side of the car-roof and join at the top or comb of the roof by overlapping. The ends maybe turned down at the caves, and may be nailed at that point.

\Vhat I claim is 1. Acar-roof consisting of a series of sheathing-strips beveled upon their upper adjacent edges and each alternate strip gained upon the lower edges, said strips being nailed to the purlin and provided with iron sections slipped over the same and interlocking, sub stantially as described.

2. In a car-roof, the e0mbination,with a series of sheathing-strips, each having its upper parallel edges beveled and each alternate strip being gained upon its lower edges, of iron roofing- sections 6 and 7, the former having the general contour of the gained strip, and the latter having in addition an outwardly-extended double fold, and free edges inclined upward and outward over said fold, substantially as described.

3. In a car-roof, the combination, with the purlin 1, of the sheathing strips 2 and 2, nailed thereto, all having bevels 3, and the strips 2, having also gains 4, the iron sections 6 and 7, the former following the contour of the strip 2, and having inwardly-turned edges 7*, lying in the gains4 and inclosing the edges 7,while the latter have inclined sides 8, out- Wardly-extending double folds 10, lying in the gains 4, and the inclined free edges 9, lying underneath the adjacent inclined portions of the section 6, substantially as described.

In testimony whereof I afifix my signature in presence of two witnesses.

FRANK G. CALDWELL.
