- My invention relates to roongplates of the kind used in the make-up of a roof of the general type illustrated and 'described Vin my patent 1,896,685, of lViay 26, 1931. vAs previously con- '5 structed,it has been found that in such roofing effective provision was not made for the carrying off "of such water as .might condense on-the under side of the 'roof plates and that there was at times a liability -for'rain water'to be forced f l by high winds through the joints formed'between the successive rows of the roofing plates and the object of my invention is to provide a rooiing plate structure which will at the same' time provide' for theready escape'of water of'v'condensation formed '15 on the underside of the plates and prevent water from being blown upwardlythrough the joints formed by the lapping plates and also to adapt theroof structure asa whole to the most advantageous embodiment of such improved plates and my inventionr consists in forming on the upper top surface ofwa rooiing plate provided with upwardly extending ribs or flanges along its sides and with a hood like formation extending from the bottom edge of the plate centrally upward to l" a point below the top edge of the plate, a pair of ribs, the lower ends of which approach but do not contact with each other and are located above the top end of the hood and which extend obliquely upward and outwardly to points at or near the side edges of the plate and in forming above said ribs an angular rib having a closed apex and legs extending from said apex obliquely downwardly and outwardly to points near to but I not in contact with the obliquely upwardly and 4-35 outwardly extending ribs thereby affording, when such plates are assembled in a roof structure, a ready outlet for water of condensation and at the same time providing effectively against water being blown upward along the surface of the plate and between it and overlapping plates and my invention also consists in certain improved features of construction in their elements of the roof structure as adapt them for usewith the improved plates. I am aware that roong plates have heretofore been designed with ribs disposed upon their upper ends intended to serve the purpose for which my ribs are provided and that the novelty of my construction lies chiefly in the angular disposition and combination of the ribs whereby I secure at the same time a more ready outflow of water of condensation and a more effective provision against the blowing of water upward through the y joint formed by lapping plates. My invention will be better understood as described in connection with the drawings which form apart ofthis specification and in which" Figure 1 is' an isometric view of a -portion of a roc-f structure of the general type of that described in my former patent but embodying my present improvements, the roofing being broken away at certain' points to better illustrate the make-up of the structure. I

Figure '7 is a'transverse section on the line 'T4-'7 of Fig.5, and* Y l- Figure 8 is af-longvitudinalsection onthe line 'F5 In the drawings, A, A, indicate roof beams. B, B, etc., my improved rooling plates provided at their upper ends with downwardly extending projections C, C, adapted to engage the upper 30' edge of the roof beam upon which the plate is laid. D, D, are upwardly extending ribs or flanges formed on the side edges of the roong plates and E is a hood like projection formed along the center of the plate and extending from its lower edge to a point below its upper edge. F, F, are ribs or projections formed on the upper top portion of the plate, the lower ends of which approach but do not contact with each other and are located somewhat above the end of the hood, leaving between them an outflow space for water of condensation, as indicated at G. The ribs F, F, extend obliquely upwardly and outwardly along the top surface of the plate to a point adjacent to or in actual contactwith the upwardly extending side ribs D, D, and the upper sides of the ribs thus provide for, as indicated at G1, G1, a ready flow of water along the ribs to the opening G. H is an angular rib having a closed apex indicated at H1 and downwardly and outwardly extending legs H2, H2, the ends of which extend comparatively close to but not in contact with the ribs F, F, so as to leave water channels, as indicated at G2, G2, while the upper surface of the legs H2 provide for the downward and outward flow of water, as indicated at G3, G3, and it will be observed that while this construction provides for the free outflow of water of condensation, it also provides a very eifective obstacle to the inflow of wind or water between the surfaces of lapping plates.

As in my former patent, cap pieces J are provided spanning the side ribs of adjacent plates and are held in position through lugs J1 which, in turn, are secured to the roof beams in any convenient way, as illustrated by means of wedges K. Where, as shown, the ribs F extend into contact with the lateral ribs D, D, the downwardly extending portions of the cap pieces J are raised or cut away as indicated at J2 so as to clear these ribs when the cap pieces are assembled with the roof plates. The lower ends of the arc shaped cap pieces are closed by transversely extending webs, as indicated at J3, and these webs are extended downward below the edges of the cap pieces J so as to come in contact with or close to the surface of the roong plate B at a point between the top of the hood E and the lower ends of the ribs F, F. It will be seen that the downwardly extending portion J3 of the cap pieces affords a wind-break directly in front of the ends of the ribs F, F.

Having now described my invention, what I claim as new and desire to secure by Letters Patent, is:

l. In a roong plate provided with upwardly extending ribs along its sides and having an upwardly extending hood like formation extending along its center line from the bottom edge of the plate to a point at some distance from the top edge of the plate, the improvement which consists in forming upon the upper side of the upper portion of the plate a pair of ribs the lower ends of which approach but do not contact with each other and which extend obliquely upward and outward and in forming above said ribs an angular rib with a closed apex, the legs of which extend from the apex obliquely downward and outward to a point adjacent to but not in contact with the upwardly extending oblique ribs.

2. A roong plate as called for in claim 1, in which. the upwardly and outwardly extending ribs extend at their upper ends into contact with the upwardly extending ribs formed along the edges of the roong plate.

3. In a roof structure comprising supporting beams, roong plates supported on said beams having upwardly extending ribs at their side edges and centrally located hood like structures extending from their bottom edges toward but not to their top edges, said plates being set in parallel rows in which the individual plates of each row are spaced apart from each other and in which the plates of adjacent rows are set in staggered relation to each other and cap pieces extending over the side ribs of the roong plates having locking lugs extending downwardly between the edges of the plates and means for securing said locking lugs to adjacent roof beams, the improvements which consist in forming upon the upper top surface of the roong plates which are overlapped by an upper row of roofing plates a pair of upwardly extending ribs, the lower ends of which approach but do not contact with each other at a point somewhat above the top of the hood like formation of the plate and which ribs extend obliquely upwardly and downwardly into contact with the lateral ribs of the plate and in forming on the upper portion of the plate above said ribs an angular rib having a closed apex and downwardly and outwardly extending legs which approach but do not contact with the upwardly and outwardly extending ribs, in forming the cap pieces with their uppermost downwardly extending portions cut away to give passage to the upper ends of the oblique ribs formed on the plate and with a transversely and downwardly extending web at their lower ends extending downward to such distance as will cause its lower edge to come substantially in contact with an underlying plate in the assembled roof structure.
