lapplied to a roof.
In roofing joints of this character, it is desirable to provide a channel of considerable depth between the lapping portions of two sheets, which channel is not only for the purpose of drainage, to carry off water which may blow into or enter the channel by capillary action from a side of the joint, but also to provide a free air space of considerable capacity within the joint. It is also found that for eflicient operation as a weatherproof joint and for strength, the upper lapping member should have an entrant portieri with respect to the channel of the lower meinber, which portion is of channel form and is spaced from the wall of the lower channel.
The primary object of the invention is the provision of an eicient joint of this type having thek characteristics noted and being strong and durable in construction and pleasing in appearance, whereby to enhance the practicability and commercial value thereof.
The invention is fully described in the following specification, and a preferred embodiment thereof illustrated in the accompanying drawing, in which- Figure l is a perspective view of a fragmentary portion of a roof embodying roofing sheets joined in accordance with my invention, and Fig. 2 is a cross-section thereof.
Referring to the drawing, I designates the sheathing of a roof and 2 and 3 adjoining roofing sheets of a roong invention.
Each of these sheets terminates at one side edge (the underlying edge when laid) in a pair of parallel ridges 4 and 5 of the same height and of inverted V-form in cross-section with a V-channel 6 therebetween. The point or bottom of this channel extends to the plane of the sheet and rests on the sheathing I as does also the outer legs of each ridge 4, 5. The top of each of these ridges is of sufficient width to be slightly depressed and form a shallow nailing groove 'I from end to endthereof. The legs of each ridge 4, 5 form oppositely inclined or upwardly convergingl plane surfaces at approximately the same angle from the plane of the sheety and the preferable width of each ridge top in practice isapproximately five-sixteenths of an inch with a height from the plane of the sheet of approximately five-eighths of an inch, and with thc preferable width of the spacstructure embodying the truncated form to provide l tion 0f Ohio Y erse the under' side of ing between the ridges at the top approximately seven-eighths of an inch. The legs of the ridge 4 are designated 8 and 9 and those of the ridge 5 are designated I0 and II. v
The other side edge of each sheet i the upper or lapping edge when laid) is provided lengthwise thereof with a single ridge broad top I3 and having its legs I4 and I5 oppositely'inclined. This ridge is adapted to fit closely down over the two ridges 4, 5 of an adjoining sheet with its top resting on the tops of the under ridges and with its legs lying fiat against the respective legs 8 and II of such ridges, as shown..
The top I3 adjacent to each side edge, where it rests on the tops of the two underlying ridges 4 and 5, is provided with shallow longitudinally extending grooves I6 which fit into the registering grooves 1 of the underlying ridges and not only facilitate nailing but indicate the line along which nailing should occur.
-The top I3 is also provided lengthwise thereof substantially centrally of its side edges with a depressed portion I1 which enters the top portion of the channel E and has its side walls spaced from the side walls of the underlying channel. The depression Il is preferably of V-form in cross-section with the upper ends of the legs thereof spaced from the upper ends of the legs of the underlying channel 6 and with the apex of the depression spaced a substantial distance. from the bottom of said channel, as shown. With this arrangement the depression I1 provides a barrier to prevent any wind, which may pass up between the legs 8 and I4 of the joint, from pass'- ing straight across the channel 6 to the top of the farther ridge 5 and carry with it moisture which may then nd its way to the roof boards between the legs II and I5. f
It is found that if the depression IT is omitted, there is a tendency for moisture, which may be driven to the top of the ridge 4 by siphonic or capillary action to follow across the smooth under side of the'top I3 to the top of the farther ridge 5 and thence pass down its leg II to the under side ofthe sheet roofing. The purpose of the depression, therefore, is to cause any wind passing to the channel 6 between the members of the joint to be deflected down into the channel, and also to 'cause any moisture which may travthe leg I4 and top I3 of the lapping yridge I2, or any moisture of condensation which might gather on the under side of said top I3, to pass down to the lower edge ol the depression and then drip into the channel 6 I2 having a insteadof passing to, the roof over the ridge 5. This arrangement also provides a drainage trough on the top of the broad lapping ridge I2, imparts strength to said ridge and provides an ample air space within the channel 6 and especially within the walls of the channels 6 and 1, all of which features are desirable in practice.
It willbe understood that the'ends of the channels 6 and I6 are open for drainage purposes.
Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent, is:
1. A lap joint for vroofing sheets comprising two metal sheets overlapping at their marginal side edge portions, the lapped portion of the under sheet including two parallel ridges of .inverted V-form forming a V channel therebetween the same in depth as the ridges and the lapping portion of the upper sheet having a single ridge for tting down over said under ridges with its legs lying flat against the respective outer legs of the under ridges and with its top bridging said channel and formed centrally of its edges with a longitudinally extending depression forming a trough and extending down into the upper portion of said lower channel vin substantially parallel spaced relation to the walls and bottom thereof.
2. A lap joint for roong sheets comprising sheets adapted to occupy overlapping relation along their lmeeting edges, the under of said edges having therein a pair of parallel ridges with inclined legs and forming a V channel therebetween with its apex extending to the plane of the sheet, and the other edge having therein a.
,single ridge adapted to t over the two ridges of the under edge with its legs oppositely inclined and seating at against the' outer legs of the under ridges and having its top resting at its respective side edges on the tops of said under ridges and formed centrally of said under ridges and in spaced relation thereto with a longitudinally extending V depression, the Walls and 'bottom of which are spaced from the walls and bottom, respectively, of said under 'channel to form a drainage trough in said channel and also a continuous free air space to the top of each leg of the channel.
`3. A lap joint for roofing' sheets comprising sheets adapted to occupy overlapping relation along their meeting edges, one of said edges having therein a pair of parallel ridges of inverted V-form in cross-section with their tops truncated and longitudinally depressed and with the channel between the ridges of V-form and extending at its bottom to the plane of the sheet, and the otheredge having therein a single broad ridge with oppositely inclined legs ttng closely against the outer inclined legs of the under ridges and with its top bridging the space between the two under ridges and having substantially :dat portions extending inwardly from each leg to a point in inwardly spaced relation to the respective inner legs of the under ridges and provided With shallow longitudinally extending grooves for nesting in the top grooves of the under ridges, said flat portions having a connecting portion of V-form extending down into said channel with its walls and bottom in substantially parallel spaced relation to the walls and bottom of the channel to form a continuous free air space in the channel from the bottom to the upper ends of its legs.
