"'T ALFRED C. LEIGH, 0F BELLEVUE, PENNSYLVANIA, ASSIGNQB TO BRAVO CONTRACT.-
ING COMPANY, A GORPORATI-ON OF PENNSYLVANIA ROOF STRUCTURE Application filed January. 3, 1931. Serial No. 506,356.
My invention relates to the construction of ships, boats, barges, scows, and lighters; and, while it is applicable to buildings of all sorts, it finds practical application in the construction of roofs for deck-houses, hatchways, and the like, and in such application I shall show and describe it. i
Fig. I is a View in side elevation of a barge, having a deck-house covered by the roof of my invention. Fig. II is a fragmentary view to larger scale, showing diagrammatically in perspective details of the structure in which my invention is found. F-ig.'III is a view similar to Fig. II showing other details. Fig. IV is a view in vertical and transverse section on the plane indicated at IVIV, Fig. III.
Barges for transportation by waterof merchandise or heavy material in bulk, decked over for purposes of protection, are provided, for facility in loading and unloading, with large hatchways. It is requisite that the roof above such hatchways shall be removable, and preferably removable in entirety, so that when removed the whole of the hatchway opening shall be free and unobstructed; it is desirable that when applied the roof shall be smooth-surfaced and watertight; and it is to the achievement of these desirable ends, simply, effectively, and economically, that this invention is directed.
The barge of Fig. I includes a hull 1 and a deck 2. Through the deck a hatchway 20 is formed, and over the hatchway a deckhouse comprising walls 3 and a roof 30 is built. The whole structure is ordinarily built of sheet steel, and structural shapes of steel. The upper edge of the deck-house wall is, by means of structural shapes, provided with a stepped flange 5, including two treads and two risers, as shown in Figs. II and III.
The roof 30 is, as a matter of practical necessity, formed of a succession of sections, arranged side by side throughout the length of the deck-house and, disregarding for present purposes the particular formation of the end sections, these sections are (and all of them are, so far as concerns themeeting edges of two adjacent sections) identical. Each section consists essentially of a web of metal, to which the numeral 4 is immediately applied,
which, although it might be level, is here shown to be curved to a low arch, to span. the deck-house walls from side to side. To the web of metal l, at opposite ends, lengths 6 "of channel beam are united, and upon these the roof sectionrests whenapplied to the stepped flange of the deck-house wall. Thecha-nnel 6 rests on the outer and lower tread of the stepped flange 5, as clearly show-11in Figs. II and III.
Along each side of a roof section: which in the assembly is to meet a like edge of adj acent section, the roof section is provided with the following structural features, illustrated in detail in Fig. IVL (1) Theweb 4 ofwhic'h the section essentially consists is provided with a downwardly extending flange. Such o a flange is conveniently formed by bending downward a marginal portion 7 of'we'b 4 and by extending such bent-down margin by securing to it a plate 9. (2) Upon the outer face of such: downwardly extending'flange a gutter is formed. This is convenientlyaac complished by securing to the flange aZi-bar 11. The free flange of the Zl-bar stands verstically, and risesto a'level slightly below' the general plane of the upper and outer surface of the web 4. The ZL-bars extend to the ends of the sections, and the gutters which they form discharge, as shown in Fig. II, to the outside of the inner riser of the stepped flange 5. The marginal flangeof plate at is. at
its lower extremity bent outward, to form exteriorly beneath the Z-bar 11 a supplemental trough. This troughalso, as shown in Fig. II, discharges beyond the inner riserofthe stepped flange 5. (4) To the upper face of web- Land adjacent the edge of the section a strip is secured. The unions here and else where may conveniently be, and preferably will be, weld' unions. v
In the assembly two roof sections are brought to position'with adjacent edges arranged asshown in FigIV, and the structure is completedby the application of aysea'ling strip 12. This is essentially a stripof steel, of suchw-idth as to rest on either side upon thewebs 4, lying snugbetweenthe-strip's 8 upon adj acent'sections, and spanning-the interval'between the downward extending flanges 7. At its ends, the strip 12 is shaped to overlie the outer faces of the channel beams 6 of the cover sections, and to overlie also the outer and lower tread of the stepped flange 5, to which stepped flange the strip at its ends may be secured, as by the bolts 13 (Fig. III). The strip carries on its nether face outstanding flanges which in the assembly depend intothegutters formed as aforesaid by the Z-bars 11. Accordingly, in convenient structure, to the strip 12 a length of steel channelbar 14 is secured, and this channel-bar in the assembly comes to place immediately above the two vertically standing flanges of the Z -ba'rs 11 of the two roof sections, with the marginal flanges of the channel depending externally of the assembled flanges of the two Z-bars, as is particularly illustrated in Fig.
.L Snch being the details of construction, and with attention directed specifically to Fig.
Y IV, thesethings are to be remarked: first, the closure which is provided of the seam between adjacent sections'interrupts the smooth exterior roof surface to the extent only of the negligible thickness of the strips 8, and 12;
V the roof is substantially smooth, Without ob- 'structions, suchas might on navigable streams be a source ofxdifliculty, because of contact of overhanging branches of trees orv of other overhanging bodies; second, the closure is of labyrinth character andefl'ective to prevent access 'of water to the contents of the barge. Such rain water as may drive or seep beneath the strip 12, and between the nether surface of the strip 12 and the upper surface of the 'webs 4;, will have access to the gutter which is formed by and between the downward extending flange upon web 4 and the Z-bar 11.
Passing through this gutter longitudinally,
that is to say, transversely, of the barge, such 7 water will be discharged at the ends, externally of the stepped flange of the deck-house wall. And if indeed'rain should drive in with such violence asto accumulate on the.
outer surfaces of the Z-bars 11, the troughs 10 will serve to catchthe small amount and deliver it externally of. the deck-house wall. It will be perceived that this cover is secure and. V adequate, without the aid of water-proof tarpaulin or the like. 7 I olaimas my invention: I
resting upon two assembled sections between the upstanding strips thereof and over lying such gutters.
2. In a roof structure for the hatchway of a barge or other vessel, secure against the weather, and offering minimum obstruction to travel, the. combination of walls with stepped flanged upper edges extending along opposite fore-and-aft edges of the hatchway,
; a plurality of roof sections adapted to be applied abeam and to rest at opposite ends upon said walls, each roof section consisting essenway walls, and a cover strip with downturned ends applicable to two assembled roof sections and in the assembly overlying the webs of the two sectionsadjacent their marginal gutter-carrying flanges, the ends of the cover strips overlying the ends of the roof sections and engaging treadsurfaces of the stepped hatchway walls.
In testimony whereof I have hereunto set my hand.
