SKYLIGHT CONSTRUCTION.

. Application filed March 14, 1924. Serial No. 699,342.

This invention relates to new and useful improvements in skylight construction, and it consists in certain improved constructions of the sheet metal supports for such struc- 5 tures, whereby to secure great strength and rigidity and tight joints by the use of only sheet metal without the use of rivets or putty for the joints.

In the drawings:

Fig. 1 is a side elevation, partly in section of the invention;

Fig. 2 is a transverse, sectional view.

The numeral 1 indicates the customary glass panels. The longitudinal bar 2 extending longitudinally between the panels 11 consists preferably of a vertical portion formed of sheet'metal bent over upon itself to produce a pair of edges 33, while the lower edges of their parallel members are 20 bent outwardly horizontally as at 4-4 and inclined upwardly as at 5-5 forming troughs on either side of the central portion to catch any water that might drip from the inner side of. the panels 1-1. A second strip 6 seals the trough by engaging the lower sides of the horizontal portions l-4e, being held against displacement by crimping its edges 7-7 around the upwardly inclined edges 55 of the central portion 33. The inner edges of the member 6 are again bent vertically at the base of the inclined edges 55, forming vertical walls 8-8, which are adapted to bear against the lower side of the panels 11 when in place. The vertical portions 88, are bent over against each other as at 99 to further strengthen the wall members 8-8.

A substantially A-shaped cap 10 is ar ranged above the panels 11 consisting of side wall members 1111 having their lower ends bent inwardly as at 12 -42 upon them selves, in spaced relation to receive the interlocking partitions of the packing members 1313 formed of lead or other suitable material. Extending vertically from the vertical central portion 2 of the lower supporting member is a T-bolt 14 which passes upwardly through an opening 15 in the top of the cap 10, the threaded end of the bolt adapted to receive a nut 16 and a lead washer 17 for holding the cap, and base portions firmly in place.

In use the various parts are assembled with the glass panels 1l disposed between the packing atthe lower edge of the cap 10 andthe vertical supports H of the base, the nut 16 firmly holding the members together.

I claim: 7

In a skylight, the combination with glass panels, of a substantially A-shaped cap including side members having the lower ends thereof bent inwardly in spaced relation upon themselves, packing members engaging the upper surfaces of the panels and having their inner edges interlocked with the lower edges of the side members, a supporting base suspended from said cap and consisting of a strip bent back upon itself to form a central substantially thin web, the edges being bent outwardly horizontally and inclined upwardly forming a trough on each side of the web, a strip covering the bottoms of the troughs and passing'around and interlocked with the inclined edges, the inner edges ofsaid strip being bent vertically at the base of the inclined edges, and said vertical edges being bent back upon themselves forming vertical walls spaced apart from said central web for supporting the panels.

In testimony whereof I- afiix my signature.

ALFRED PEKKALA.
