CAR-ROOF.

SPECIFICATION forming part of Letters Patent No. 720,949, dated February 17, 1903.

flerial No. 116.506. (No model.)

To all whon t it may concern.-

Be it known that I, WILLIAM J. MOCULLEY, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Oar-Roofs, of which the following is a specification, reference beinghad therein to the accom panying drawings.

. The invention relates to a car-roof composed of a multiple of metallic plates or sections designed as a covering for the wooden roofs of freight-cars; and it consists in the particular construction of the sections, the joint or connection between the sections, and in the construction of a cap for the peak-joint and a connection between such cap and the sleeper which constitutes a support for the runningboards, all as more fully hereinafter described, and particularly pointed out in the claims.

In the drawings, Figure l is a sectional perspective view showing my improved roof applied to a freight-car. Fig. '2 is a plan view thereof, showing part of the plates of the roof in position as in the course of building the roof. Figs. 3 and 4 are perspective views of the two plates from which I preferably make my roof. Fig. 5 is a section through the peak-joint, showing the parts in position ready tobe connected together. Fig. 6 is a perspective view of the peak-cap and the hook-plate thereon. Fig. 7 is a section through the peak-cap, showing the hook of the hooked plate engaged with the sleeper for the runhing-board.

A designates the board covering of an ordinary freight-car supported upon the purlins B, and 0 represents the oarlines.

D is the ridge-timber, and E designates the plates.

F and F are the metallic plates of which my roof is formed. The plate F is provided at two edges with flanges which extend parallel with the side edge thereof, and in this particular embodiment of my invention I show the flanges in the form of a double inverted trough a a, with the gutter b. At the lower edge is a flange 0, adapted to extend down the side of the plate and be secured thereto, preferably with a bead or flexible portion d therein to allow a slight movement of the plate F without danger of breaking it.

The plate F is provided upon two edges with the double spring-hooks e 6. These hooks e e are of a size to engage over the flanges upon the plate F and when engaged thereover to spring upon the flanges of the plate F and be clamped'thereon by the spring action of the hooks e e. I refer to the hooks e e as double hooks, because they are, in efiect, a hook at each edge, which engage with and grip beneath the edges of the flanges on the plates F and F, as plainly shown in Fig. 1.

Instead of making the two plates F and F with differing flanges I may make the plates both like the plate F. Except as hereinafter described I prefer the construction with the two kinds of plates.

In laying the roof the plates F and F will alternate upon oppositesides of the peak, as shown in Fig. 2, the flange along the upper edge thereof extending along the peak, while the flange along the side will extend from the peak transversely of the roof to the lower edge thereof. The plates F are then laid upon the roof with their flanges sand 6 overlapping the flanges of the plates F and are forced thereover from the position shown in Fig. 5 to that shown in Fig. 1, the spring of the metal permitting this, and when engaged, as shown in Fig. 1, the double hook of the flanges e 6 will engage in the hooks or recesses upon the edge of the flanges of the plate F and tightly clamp the parts together.

By making the gutter b in the flanges of the plates F any water that may be driven by heavy winds up under the edges of the flanges will be carried in the gutter to the lower edge of the roof and fall off at the side. This construction of joint between the plate-sections formsa flexible interlocking joint, permittin g a slight movement of the plates in relation to each other by the flexing of the metal without danger of injuring the joint and at the same time producing a water-tight joint between the plate-sections.

In order to cover-the opening H at the intersection of the plates on the peak, I provide the caps I, having the intersecting radiallyextending channels 7?. fitting over the interlocking flanges or hooks of the plates and extending a short distance thereover, so as to prevent the admission of water through the roof at that point. This plate or cap is provided with a central aperture J, through which is passed a clamping-bolt K, passing through the ridge-timber D and acting to hold the entire metallic roof in position. In order to cover the bolt-opening J, I provide a supplemental cap L, having a dovetail groove on its under face, which is adapted to engage the dovetail flanges M upon the upper face of the cap I.

In order to secure the sleepers O,upon which the running-boards are secured, without necessityiof bolts through the roof, I provide the supplemental cap L with ahook P, adapted to engage in the notch Q in the upper middle portion of the sleepers O, as plainly shown in Fig. 7, the sleeper abutting at one edge against the cap-plate and being held from movement in the other direction by the hook P. As this sleeper has opposite inclines on its under face fitting the top of the roof, it is obvious that it cannot be moved endwise without being raised and that it cannot be raised Without the disengagement of the supplemental cap L. To remove the cap I with the supplemental cap L and 'the hook P, the nut on the lower end of the bolt K may be removed, when the entire cap and hook may be removed vertically together. When the nut is screwed up on the under side of the ridgetimber, the parts are held tightly.

What I claim as my invention is- 1. In a car-roof,a metallic plate having upon its edge a double spring-hook and a complementary plate having upon its edge an upwardly-projecting rib or flange, complementarily shaped, with which the spring-hook of the first-mentioned plate is adapted to engage and be clamped thereon.

2. In a car-roof, the combination of a metallic plate having upon its edge a flexible double spring-hook and a complementary metallic plate having upon its edge a complementary spring-flange.

3. In a car-roof, the combination of a metallic plate having upon its edge a flexible double hook and a complementary plate having upon its edge a complementary flange formed with a gutter therein.

4. In a car-roof, the combination of a metallic plate having a double spring-hook upon its edge, of a complementary plate having a complementary flange upon its edge with which the first-mentioned hook is adapted to engage, said flange being composed of the inverted-trough sections a a, and the gutter 1) between.

5. In acar-roof, the combination of metallic plates joined at the peak and at their sides, of a peak-cap for the meeting corners of the adjacent sections having channels formed in its under face and an opening therein through which the securing-bolt is adapted to pass, and a supplemental cap detachably arranged upon the peak-cap and covering the bolt-opening in the latter.

6. In a car-roof, the combination of the metallic plates secured together along the peak and at the sides of the plates and a cap for the meeting corners of the adjacent sections having a bolt-hole centrally therethrough, of a supplemental cap detaohably engaging the cap-plate and covering the bolt-hole, and a connecting member joining the detachable cap with the sleeper for the running-boards.

7. In a car-roof, the combination with the metallic plates, of a series of apertured peakcaps arranged over the meeting corners of adjacent sections, supplemental caps detachably arranged over the openings in the peak caps, sleepers for the running-boards, and connections between the sleepers and the supplemental caps.

8. In acar-roof, the combination with a metallic roof-sheathing, of a series of caps arranged over the corners of the adjacent sections, a supplemental cap detachably secured thereto and covering the bolt hole therethrough and a hook thereon engaging the sleepers for the running-boards.

9. In a car-roof, the combination of the metallic sheathing, of a multiple of connected metallic roof-sections thereon, a series of caps arranged over the meeting corners of adjacent sections, each cap having a bolt-hole formed therein, a dovetail flange upon the caps, a supplemental cap having a dovetail recess engaging said dovetail flanges and a hook on said supplemental caps adapted to engage the sleepers for the running-boards.

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

WILLIAM J. MoCULLEY.
