, DRAINAGE FOR ROOFS AND SKYLIGHTS 7 Filed June 19, 1930 1 wise of the purlins and illustrating features Faker-lied June 28, 1932 I rain ARHG SHUIEAN, fill @EIIEADTIQPHEA, PENNSYLVANIA, ASSIGN'OR T0 PENNSYLVANIA WIRE GLASS @QMPANY, 01 PHELADELIPHIA, PENNSYLVANIA, A (EGRPORATIOEQ' @h NEW JERSEY DRAINAGE EQQFS AND SKYLTGHTti i seam tiled Time is,

der the felt on which the overlying glass is laid so as to provide channels between the felt and the underlying glass or other support through which the water of condensation passes from'the inside face of the overlying sheet onto the outside face of the underlying sheet.

The invention also comprises the improvements to he presently described and finally claimed.

To the following description reference will he made to accompanying drawing forming part hereoi and which Figure l is a sectional view taken crossof the invention. m

Fig. 2 is a. perspective view of. a crimped plate embodying features of the invention.

Fig. 3 is transverse sectional view taken on inc 3--3 of Fig. Land is at similar view taken on the line 4l-t of Figure l.

Tn the drawirg 1 indicates a crimped plate which may he made of appropriate metal or material. The plate is provided with anchors 2 and, as shown, they are of the form of hoolrlilre legs. 3 indicates purlins upon which the underlying sheets ioii corrugated glass are supported. The overlying sheets 5 of corrugated glass in Fig. 3 rest upon strip of felt or thelike 6, which in turn rests upon the underlying sheets of glass in the structure shown in Fi at, the sheets oi glass rest upon s filler strap 7 conforming to the corrugations in the glasaand it is supported upon a strip of felt 6 which mturn rests u on a purlin 3. lncldentally it may he said t lat the devices 8 and 9' prevent the glass from sliding endwise oh? the root, and the device if s. dashing.

The crimped or corrugated plate or element 1 underlies the strip of felt or the like 6 and in the felt and the crimps provide open passages indicated at 11. Water of condensation on the ini. face of the sheet of glass 5 at the righthand in Fig. 1, runs out through the passages 11 onto the outer face of the underlying sheet of glass 4%, and water of condensation from the under face of the sheet 4 runs out through passages 11 at the left in 1 outside of the dashing 10. In this Way good I and efiicient drainage is provided.

It may be remarked that the anchors 2 provided on the crimped plate 1 are spaced apart and arranged at the side edges near one end of the plate and when this is done they serve their purpose as anchors without interfering with the drain passages ll.

in referring to felt or the like in connection with the element 6, the intention in both the specification and claims is to include any material into which the crimped elements 1 may be embedded in substantially the mannor described.

The strips 6 and fillers '3 may he spaced from the top edges of the purlins, and when this is done pockets 1% are provided between the strips, p'urlins and underface of the glass, and these pockets may accumulate moisture of condensation which finds way to the outside by the channels ll.

It will be obvious to those skilled. in the art to which the invention relates that rnoditications may he made in detail of construction and arrai-lgeme nt and matters of mere form without departing trons the spirit of the invention which is not limited to such matters or otherwise than the prior art and. the appended claims require.

tion parallel to the axis of the hoo I claim:

1, For roofs or skylights having a strip of felt upon which corrugated glass is laid, drainage means com using a crimped plate arranged under the elt strip and provid ng drain channels, said crimped plate havmg at one end marginally arran ed space hooklike legs enga 'ng the roo structure, the crimps in said p ate extendingiin a direced portion of sald legs.

2. In a sloping roof or skylight structure the combination of a corrugated sheet of glass, a support for the corrugated sheet of glass, a felt strip interposed between the sups port and sheet of glass, and a crimped plate embedded in the strip of felt and providing drainage channels, the crimps in said plate sloping parallel to said roof.

3. In a sloping roof or skylight structure the combination of a corrugated sheet of glass, a support for the corrugated sheet of glass, a felt strip interposed between the support and sheet of glass, and a crimped plate embedded in the strip of felt and roviding drainage channels, said crimped p ate having anchors that engage the support and the crimps in said plate sloping parallel to said roof.

n a sloping roof or skylight structure i the combination of purlins, strips superposed v on and spaced from thetop edge of the purlins, corrugated sheets of glass supported onthe strips, there being pockets provided between the tops of the purlins and the glass and the stri s for the accumulation of moisture of con ensation, and crimped plates arranged on top of the purlins and under the strips providing drainage from the pockets, the crimps in said plates sloping parallel to said roof. I

5. In a $10 ing roof or skylight structure the combination of purl-ins, corrugated sheets of glass supported on said purlins and spaced therefrom, there being provided ockets between the tops of said purlins an said glass for the accumulation of moisture of condensation, and crimped plates having longitudinal crimps therein slopin roof arranged between sai purlins and said glass to provide drainage from said pockets.

RNO SHUMAN.
