Application September 14, 1934i, Serial No. 743,987 il claims. (c1. ics-ic) This invention relates to improvements inskylights, and more particularly to the support-bar and cover-bar structures of skylights.

One object of this invention is to provide an improved skylight construction in which a packing and a packing-bar are covered by a coverclarnp bar.

Another object of this invention is to provide an improved skylight construction in which a support-bar vstructure is made of a plurality of simple bars or elements to provide a rigid structure at low cost.

Another object of this invention is to provide an improved skylight construction in which varim ous support-bar structures are rigidly and economically joined together.

Another object of this invention is to provide an improved skylight construction in which an improved end-plate or glass-stop is provided for preventing the glass from sliding endwise from under a cover-clamp bar.

With the above and other objects in view, this invention v includes all improvements over the prior art which are disclosed in this application. In the accompanying drawings in whichone way of carrying out the invention is shown for illustrative purposes:

In the description and claims, the various parts, are identied by specic names for convenience,

lout they are intended to be as generic in their 50 application as the priorart will permit.

` Referring to the drawings, the skylight construction, generally indicated by the numeral 25, includes a ridge-bar 2l, side-bars 22, hip-bars 23 and a center-end-bar 24. In their main essentlals, these various bars are substantially identical in cross-section, and therefore a description of one of them will serve for all.

One of side-bars 22 (Figs. 1 and 2), for example, consists of two main parts, a support-bar structure 25 and a cover-clamp-bar structure 2li. The support-bar structure 25 consists of a main support-'bar 2l having a body-portion 28 and two downwardly-extending legs 29, the lower edges 34 of which legs rest in the bottoms of the V-shaped channels or portions 3l of a support-clamp bar 32. The V-shaped channels or portions 3l are m formed on opposite sides of the body-portion 33 of the support-clamp bar. Supported on the body-portion 33 of the support-clamp bar 32, is a body-portion 34 of a brace-bar 35. .Connected to the body-portion 34 of the brace-bar, are sub- 15 stantially-straight upwardly-diverging legs 36, the 4top edges 3l of which engage the main support-bar 2l at the juncture of the legs 29 and body 28. The body 28 consists of the central depressed portion 38 and the sloping portions 39, which latter, with the upper portions of the legs 29, form inverted V-shapedr channels within which the top edges 3l of the legs 36 are engaged.

Extending across and supported upon the main support-bar 21, is a strip of packing 40 which 25 may be of any suitable soft material such, for example, as asphaltum-impregnated felt roofing, rubber, or'any other suitable yielding material. Resting upon the packing 40, are the glass plates 4l of me skylight. The glass plates 4| win ordi- 3 narily be spaced apart somewhat as shown. Supported on top of the glass plates 4l isl a strip of waterproof packing 42 of rubber, asphaltumimpregnated felt roofing, or other suitable yielding, waterproof material. On top of the packing- 5 strip 42 is a packing-bar 43 of relatively-thin sheet-metal having oppositely-bent feet 44 resting on the packing-strip 42. The feet 44 have greater bearing width than the thickness of the sheet-metal of the packing-bar 43, thus avoiding 40 any tendency to cut through the packing-strip 42. On top of the packing-bar 43 is a coverclamp bar 45 of relatively-thick sheet-metal, which may be several times as thick as the packing-bar 43. 45

Extending up through holes through the various parts and between the spaced glass plates, are bolts 46. The head of each bolt 46 engages against the under side of the support-clamp bar 32 and a nut 4l is threadedly engaged on the 50 bolt tightly against the center depressed portion 38 of the main support-bar 2l, thus locking the main support-bar 2l, the support-clamp bar 32 and the brace-bar 35 rigidly together to form 55 alight, strong main-support-bar structure .for the skylight.

Each bolt 46 has a threaded extension 46 above the nut 41. Mounted loosely on the extension 48 is a sleeve 49 of yielding material such, for example, as lead, to avoid risk of chipping or cracking the glass plates 4| by contact of the latter with the bolts. Threaded on the upper end of the extension 48 is a nut 58 which presses the cover-clamp bar 45 down and brings the lower edges of the legs of the latter into firm engagement with the glass plates 4|, and clamps the Liter against the packing-strip 40 on the top 0! main support-bar 21, at the same time causing the feet 44 of the packing-bar 43 to yieldably clamp the packing-strip 42 against the glass plates so`as to prevent entrance of water either between the packing-strip and glass plates or between the feet 44 and packing-strip.

By having the packing-strip 4|] entirely covered by the cover-clamp bar 45, it is protected against deterioration by light.

The V-shaped channels 3| not only serve to firmly hold the legs 29 of the main support-bar 21, but also serve as drain-channels to conduct away water of condensation that forms on the under side of the skylight.

The bars 21, 32, 35, 43 and 45 are preferably made of sheet-metal, so formed and assembled as to make an economical, strong construction.

The lower end of main support-bar 21 has portions of the legs cut away to leave an extension 5| (Fig. 8) of the body 28 (Fig. 2). The extension 5| has a hole through which is passed a screw 52 which threads into the body 53 of a glass-stop or end-platel 54, which is preferably made as a rigid, preformed member, such, for example, as a casting. Clamped between th head of screw 52 and body 53, is one end of a curbashing 55, which is preferably of sheet-metal of general Z-shape as shown, with its lower reach 56 provided with a hole through which passes the bolt 51 to hold the curb-flashing 55 firmly in place. The curb-flashing reach 56 is bent to U- shape at its upper end 58 around the end-of a curb 59 which is also held by bolt 51, which curb 59 has its lower end 60 along the front of the Wood orv masonry of the building. The curbflashing 55 is provided with a drainage-hole 62 at the end of each bar 22 to carry away the condensation water carried along the channels 3| (Fig. 2). The curb-flashing 55 and curb 59 extend along from one extension 5| to another and serve to prevent rain from driving up under the skylight.

The lower reach 63 of the end-plate or glassstop 54 engages against the vertical portion of the curb-flashing 55, and the upper reach 64 extends past the ends of glass-plates 4| to hold them from possibility of sliding endwise out from under the cover-clamp bar 45, which latter bar extends over the top of the reach '64 (Figs. 8 and 9) A weather strip 65 (Figs. 8 and l0) preferably formed of sheet-metal, occupies the position shown in Fig. 8 between each two extensions 5| of successive main support-bars 21, so as to prevent rain from driving up under the lower edges of the glass-plates 4|.

'I'he manner of connecting the ridge-bar 2| with two oppositely-extending side-bars 22 is shown in Figs. 1, 2 a'nd 8. The main supportbars 21 of the two side-bars 22 have oppositelyextending overlapping body-extensions -66 supported on the body 28 of the ridge main supportbar 21. The support-clamp bars 32 of the two side-bars 22 have oppositely-extending, overlapping body-extensions 61 engaged against the under side of the support-clamp bar 32 of the ridgebar 2|. parts 61, 32, 28 and 66 and clamps the parts firmly together by aid of a nut 69 threaded on the bolt 68.

Bolt 68 has a top-extension 18 which extends up through packing-strip 1| which latter rests 10 on the ends of packing-strips 42 of the side-bars and is clamped in position `by the feet of a packing-bar 12 similar to packing-bar 43, except that the feet are at an angle as shown. On top of the packing-bar 12 is a coverclamp bar 13, 15 generally similar to cover-clamp bar 45. A nut 14 threads on bolt-extension 10 and serves to clamp the parts 1|, 12 and 13 down in position as shown. Where jack-bars (not shown) are employed, the mode of connection of two jack- 20 bars to a hip-bar will be similar to the described way of connecting two side-bars to a ridge-bar.

The manner of connecting the end of ridge-bar 2| with two side-bars 22, two hip-bars 23 and a center-end-bar 24, is illustrated in Figs..l, 2, 25 4, 5, 6 and '1. A rigid, preformed, upper couplingplate 15 which may be a casting, has a portion which extends beneath the body 28 of the main support-bar 21 of ridge-bar 2|, to which body 28 the plate 15 is secured by the screw 16 which 30 threads into the plate 15. The upper couplingplate 15 has different parts suitably shaped and sloped as shown to extend beneath body-portions 28 of the side, hipand center-end-bars, to which body-portions 28 the coupling-plate 15 is 35 connected by screws 11 threaded into the coupling-plate 15.

A rigid, preformed, lower coupling-plate 18, which may be a casting, has a portion which extends beneath the body-portion 33 of the sup- 40 port-clamp bar 32 of 'ridge-bar 2 to which bodyportion 33 it is secured by bolts 80 which extend upward through and clamp parts 18, 33, 34, 15 and 28 together by means of nuts 8| screwthreaded on the bolts 80. Lower coupling-plate 45 18 has different parts suitably shaped and sloped as shown to extend beneath body-portions 33 of the support-clamp bars of the side, hipand center-end-bars, to which body-portions 33 the coupling-plate 18 is connected by bolts and 50 nuts 82.

Bolts have upper threaded extensions 83 which extend up` through packing-strip 1|, packing-bar 12 and the cover-clamp bar 13 and have nuts 84 threaded on the extensions 83 to clamp 55 the parts together. The cover-clamp bar 13 of the ridge-bar is of somewhat different crosssectional form from the clamp-bars 45 as necessitated by the angle at the crown or apex of the skylight. The cover-clamp bar also has side- 60 cutout portions 85 to permit the passage thereunder of the cover-clamp bars `45 of the sidebars 22. The .side-, hipand center-end coverclamp bars where they come to a junction, are suitably cut to ilt into overlapping relation as 65 shown.

The invention may be carried out in other specific ways than that herein set forth without departing from the spirit and essential characteristics of the invention, and the present em- 70 bodiment is therefore to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein. 76
