" CAR-ROOF.

sPEoIFIcArON forming part @riet/eers :Latenty No. 655,941, dated August 14, 1900.

Application filed May 21, 1900.

To all uh-0 7@ itmctyjcolwen.: Beit known that-I, DELMAR C. ROSS, a citi- 'zen of the United States, residing at Detroit, inthe county of Wayne and Stateof Michigan, have invented certain new and useful Improvements in Car-Roofs', of Vwhich the following is a specilication, reference being had therein to the accompanying drawings.-

The invention relates 'to a car-roof composed of -a multiple of plates or sections designed particularly as a metallic covering for the wooden roof-boards of an ordin ary freightcar. y

The invention consists in the peculiar construction of the sections and in their combination, wherebyperfect flexibility is obtained by joints directly'niade'between the sections themselves and the attachment to thev car.

It further consists in the peculiar construction of a cap for'the peak-joint, and, further,

. inthe construction, arrangement, and combinations hereinafter described, and particularly pointed out in the claims.

In the drawings, Figure 1 is a sectional perspective of the upper portion of arcar, showing my improved metallic roof applied thereto. Fig. 2 isa perspective view of one of the sections complete and of the upper or peak end of complementary sections on opposite 'sides of the peak. Fig. 3 is a section, taken on line x so', Fig. l. Fig. 4 is a sectiontaken through the cap and sleeper constituting the support kfor the running-boards. Fig. 5 is a section on line y y, Fig. 4. Fig. 6 is a perspective View of the cap and housing. Fig. is a diagram View showing the manner inV which the joint islf'ormed between adjacent sections, and Fig. 8 is a plan View of the roof with the running-boards and caps removed.

A designates the board covering of an ordinary freight-car, supported upon the purlins-B and carlines C.

' D is the ridge-timber, andD' the plates.

G and G represent metallic sheets adapted `to be arranged upon opposite sides of the roof` and extending from the peak to the lower edge-'thereof'. These two sections are alike, except a slight addition to the l section G'A at the peak, which will-be more fully hereinafter described. I will first describe those parts which are alike in two sections G and' G'. The sections themselves consist of fiat plates Abody of the plate.

as shown in Fig. 5.

serial No. 17,469. (No model.)

which rest upon theroof A and, as before described, extend from the peak to the lower edge. At the lower edge these plates have an extension A', formed in the shape of a 'cient dist-ance to form what I call a lexible portion or section between the plate G .proper and the Vertical flange B', Which forms the'securing-flange. This lange'is formed by a continuation of the plate G beyond the curved bend orbead A', as clearly shown in Fig. 2. The flange B extends down the side of the car and is secured thereto by nailing or otherwise, so as to form a tight-joint; Y This construction is best illustrated in Fig; 2. The oppositefsides of the plate Ghavelockinghooks H in the shape of an involute hook extending from the top edge thereof down to substantially the lower edge thereof-that`is, down to thelower edge of that portion of the plate which rests upon the roof. These flanges terminate preferably in the vertical jointflange J. l At the upper edge of' the plates G G' are 4formed the inverted hooks or trough-shaped flanges L. Upon the plate G these troughshaped flanges extend across only the main Upon the plate G' they are made to extend across the body of the plate and at one side have the extension M, which overlaps the joint between the adjoining sections, as clearly shown in Fig. 8.

In assembling the plate-sections to form the 'roof'. the sections G are arranged upon one side 'and the sections G'upon the other side of the peak or ridge. The adjoining plates in each series are secured together by engaging the rolls or hooks H, as shown in Fig. 7,

the plates being first placed end to end and at an angle to each other to permit of this engagement of the hooks, and the parts yare then slid upon each other until they stand .side by side, when they are turned down into parallelism, as shown in Fig. 1, resting fiat upon the wooden roof A., I'n vmoving them down into parallelism or into a common plane the locking-flanges J are moved into contact and form a tight joint between-the sections, The hooks L of thev plates G' are overlapped upon the hooks L of the plates G, and thus serve to tie the twosectionsI together at the peak. The extensions M cover the joint at the peak, as shown in Fig. S, the lower ends being nailed through the securing-flange B'. The upper ends are secured by means of bolts O, which pass through apertures din the flanges L, as clearly shown in Fig. 4. The sections thus being connected together form a continuous metal sheathing from one edge to the other of the roof. Between the lower edge of the plates G and the roof is a liexible section A', which permits the plates Gto move lengthwise upon the wood covering. This is also permitted by the flexible connection formed by that portion of the hook L which extends between the plate G and the bolt, as shown in Fig. 4. The plate is therefore free to move either as a single plate o1' as connected plates to or from the line of the ridge, as the joints at the top and bottom are tiexible enough to permit this movement, while the joints on the sides permit it by one hook H sliding in its adjoining or interlocking hook. The plates are also flexibly connected together at their sides by these interlocking hooks and may move to or from each other orbe turned at an angle to each other without destroying the joint. This, it will be noticed, is accomplished without the addition of any additional cap plates, but by interlocking ianges on the edges of the plates themselves. It will be noticed thatv these plates are so securely fastened at top and bottom and are so securely fastened to each other at the edges by interlocking hooks forced tight-ly together (at the anges J) that there is no possibility ot rattling or shaking, and even if the parts should rust and wear to an appreciable extent the roof-sections thus constructed may be used with any desired form of cap for the corner- 'joints at the peak and any desired form of running-board may be placed thereon. The form of cap and running-board connection is shown particularly in Figs. 3, 4, 5, and 6, and is ot' the following construction:

In order that rain and snow may be `effectually prevented from entering the car through the exposed portions of the jointsnamely, at the meeting corners of adjacent sections-I provide caps or plates P, covering said corners of the plates, and a hood P', adapted to cover the bolt O and bolt-hole P2 in the cap.A In formation the cap referred to consists, essentially, of a four-way hood having intersecting radially-extending channels e, f, g, and h formed in its under side, the said channels terminating in the housing Il referred to, arranged centrally of the hood. The cap is likewise provided with oppositelyarranged and upwardly-extending perforated earsjj, the function of which willlbe hereinafter described.

7c k designate lugs upon opposite sides of the interior of the housing. The semicircular base-sections Z Z are arranged at an angle to each other to permit of the cap lying fiat upon the roof.

In placing the cap, with its housing, in position it is iirst arranged over the head of the bolt and then moved in a lateral direction to bring the lugs on the interior of the housing upon opposite sides of` the bolt-shank beneath the head, as plainly shown in Figs. 4 and 5. Upon clamping the bolt by the turning of the nut d the cap is clamped upon the roof-sheathing.

The reference-letter Q designates the usual sleeper which constitutes the support for the running-boards R, and this sleeper I arrange between the perforated earsjj, before referred to. such manner as to lie liat upon the roof, and a bolt S, Fig. 5, extends through the ears and said sleeper, secu rely holding the latter in its proper position. The running-boards R are arranged upon and secured to the sleepers in the usual manner.

Vhile I have shown and described a particular type of cap, the latter being in the form of a hood, with grooves or channels formed in its lower face, I do not care to limit myself to this construction, as the cap may consist simply of a Hat plate having a bolthole formed therein, with the housing arranged over the bolt-opening.

What I claim as my invention is l. A metallic roof-section comprising a plate, locking-hooks upon opposite sides of the latter, au inverted trough at one end of the plate, the edges of said trough being in theplane of the plate extending transversely and at some dista-nce beyond the plate at one side of the latter, and a securing-liange upon the opposite plate end.

2. A metallic roofsection comprising a plate, locking-hooks upon opposite sides of the plate, a securing-flange depending from one of the plate ends, and an inverted trough carried by and having its inner edge integral with the opposite plate end, the trough projecting laterally beyond the edge of one side of the plate and having its outer free edge in the plane of the plate, substantially as and for the purpose described.

3. In a metallic roof composed of roof-sections, a cap for covering a section-joint, comprising a hood having radiallyextending channels formed in its under face and an opening formed therein, through which the securing-bolt is adapted to extend, and a housing, constructed to receive the bolt-head, covering the bolt-hole formed in the cap.

4. In a carroof,the combination witha roof sheathing, a multiple of connected metallic roof-sections thereon,a series of caps arranged over the meeting corners of the adjacent sections, each cap having a bolt-hole formed therein, a bolt extending through each cap, and a housing, constructed to receive and support the bolt-head, covering the bolt-hole formed in the cap.

5. In a car-roof,the combination with a roof sheathing, a multiple of connected metallic roof-sections thereon,a series of caps arranged The sleeper is hollowed out in over the meeting corners of the adjacent sections, each cap having a bolt-hole formed j therein, a bolt extending through each cap, a

housing, constructed to receive and support the bolt-head, covering the bolt-hole formed in the cap, oppositelyarranged upwardlyextending perforated ears upon each cap, a sleeper intermediate each pair of ears, a bolt extending through said sleeper and ears and the running-boards supported upon the sleepers.

6. In a car-roof, the combination with the roof-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 housing for each cap covering the bolt-hole, oppositely-arranged lugs upon the interior of the housing,.a bolt for each cap, a bolt-head engaging the lugs within the housing, and a bolt shank extending through the cap and sections, and a nut for each bolt, substantially as described.

7. In a metallic roof, the combination of two adjoining section-plates, and a joint conf necting the adjacent portions of said plates, comprising two involute hooks one upon the meeting side of each plate, the said hooks being bent in the same direction and adapted to be engaged one within the other, and abutting anges upon-the free ends .of the hooks, the relative arrangement and proportion of the parts being such that when the section-plates are turned into a common plane on the engag-y ing hooks the flanges will abut.

8. In a metallic roof, the cdmbination of two adjoining section-plates and a joint connecting the adjacent portions of said plates, comprising two involute hooks, one upon the meeting side of each plate, the said hooks being bent in the same direction and adapted to be engaged one within the other, and abutting ilanges upon the hooks'formed by bending upwardly at substantially right angles to the plane of the plate the free end of each hook, the relative arrangement and proportion of the parts being such that When the sectionplates are turned into a common plane on the engaging hooks the anges will abut.

9, A car-roof comprising a roof-frame and covering, of a metallic covering consisting of a multiple of plates extending from the peak to the lower edge of the sheathing, sliding joints connecting the edges of adjoining plates and a iiexible connection between the main section of each sheet and the car at the lower edge of each sheet, and a yielding connection at the peak, whereby each sheet may move longitudinally in relation to the adjoining sheets, without bending or 'buckling 10. A metallic car-root' consisting of a series of plates extending from the peak to the lower edge of the sheathing, a connection with the car at the lower end, a exible section between that car connection and the plate, sliding flexible joints connecting the adjoining plates, and a flexible joint at the upper end of the plate, for the purpose described.

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