TOSEPH SYLVAN, OF CHICAGO, ILLINOIS GLAZING BAR FOB SKYLIGHTS AND THE LIKE.

I Application filed June 16, 1921. Serial No. 477,886.

To all whom it may concern:

Be it known that I, JOSEPH SYLVAN, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Glazing Bars for Skylights and the like; and I do hereby declare that the following is a full clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in glazing bars for skylights and the like and consists of the matters hereinafter described and more particularly pointed out in the appended claims.

One of the objects of the invention is .to provide a simple and eflicient glazing bar which may be made from sheet metal and which so grips or clamps the marginal parts of the glass panels of the skylight as to form a watertight seal between the glazing bar and panel without the use of putty or like material. 1

Other objects of the invention as well as the several advantages thereof will more fully appear as I proceed with my specification.

In the drawings Fig. 1 illustrates a partial transverse vertical sectional view through a skylight construction embodying my improved glazing bar.

Fig. 2 is a transverse vertical section on an enlarged scale, througha glazing bar and the marginal parts of adjacent glass panels, the plane of the section being indicated by the line 2-2 of Fig-1.

Fig. 3 is a detail view illustrating the manner of introducing the margin of a glass panel into one of the glazing bar strips.

Fig. 4 isa perspective view of a fragment of glazing bar strip made in accordance with my invention. I

Fig. 5 is a detail perspective viewof one end of a cap strip associated with my improved glazing bar.

In general my improved glazing bar includes -a channel or :V-shaped'sheet metal strip, the top part of one of the side members of the strip being bent to overhang but being-spaced from the top edge of the other side member-toprovide a laterally opening slotnearthe top of; the strip; This slot receives one margin of a glass panel and when the strip rest with its bottom edge upon the stringers of a skylight and a panel'is entered into the slot, the weight of the panel will cause the strip to rock or tilt laterally toward the panel about its bottom edge. When the strip is thus rocked, its top parts which definenthe slot, engage andsecurely clamp the top and bottom surfaces of the marginal part of the panel.

Referring now in detail to that embodiment of the invention illustrated in the accompanying drawing, 10 indicates a truss forming a part of a skylight structure which truss includes a horizontal bottom barll, an upright middle bar 12 and oppositely inclined roof rafters 13 which are fixed at their ends to the ends of the bottom bar and to the topend of the upright middle bar 12. Brace bars 13 are provided to connect the middle parts of the roof rafters with the middle part of the horizontal bar which rests at its ends upon and is fixed 'to the usual curb walls 14 (only one of whichis shown in Fig. 1) defining the sides of the skylight opening.

Connecting the trusses together are longi tudinal' top or inner stringers 15, bottom or outer stringers 16 and intermediate stringers 17, all preferably made of angle bars. Secured'to the bottom and intermediate stringers 16 and 17 are combination or eaves gutter strips 18 and 19 respectively and engaging both top stringers -15 isa one-piece ridge strip 20, said strips all being made of. sheet metal bent into suitable form.

The combination or eaves gutter strip 18 includes a hooked flange 18 which engages the stringer. 16 as shown, and two upright webs 18 -18 respectively spaced from each other and forming stop shoulders for] the hooked flange 19 which engages the inter,-

mediate stringer 17: as shown, and two upright webs 19"--. 19 respectively which are spaced from each other and form stop shoulders for the outer ends of the top glazing bars 24 and top panels 25. In the web 19 is a plurality of holes 19 The web 19 terminates in a vertical depending hook flange 19 and said flange together with the web 19 receives and holds a deflector plate 26 which prevents the wind from blowing in through the openings 19 Between the hook flange 19 and the web 19 the strip is formed to provide an outwardly opening groove 27 the purpose of which will presently appear.

The ridge piece 20 has oppositely inclined side members 20* which are folded upon themselves to form outwardly opening grooves 20 and hook flanges 20 which engage the top stringers l5.

- The glazing bars 2124c being identical in form and construction, a detailed description of one will suflice for both. Each bar is made up of a pair of substantially channeled or V-shaped sheet metal strips 2828 and each strip comprises inner and outer sidewalls or members 29 and 30 which are connected together along their bottom edges and diverge upwardly and outwardly therefrom. The inner side member 29 is of a height greater than the outer side member 30 and its top marginal part is bent at substantially a right angle to form a web 31 which overhangs but is spaced from the top edge of the member 30 to provide a. laterally opening slot 32'of a width greater than the thickness 'of'the panel used in connection therewith. The web 31 terminates in an upturned flange 33. n

The panels 22-25 are glass panels and are preferably of the kind having the ribs 34: on the underside arranged parallel with the glazing bars. The glazing bars 21 24 are shorter in length than their associated panels; the glazing bars 21 engaging at their ends against the shoulders 18 and stringers 17 and the glazing bars 24 engaging at their ends against the shoulders 19 and stringers 15 respectively.

' To assemble the panels and glazing strips said strips are placed in pairs upon the sky light framing and are spaced apart a distance substantially equal to the width of the panels. One strip of each pair is then made to assume a substantially upright position as shown in Fig. 3 when the margin of a panel is introducedinto'the slot 32. When this has been done, the top. edge of the outer side member of the strip will engage in one of the grooves between adjacent ribs 34: on the underside of the panel when the weight of the panel 'will cause the strip to tilt or rock laterally about its bottom edge until the outer edge of the web 31 engages the top surface of the panel as shown in dotted linesin Fig. 3. When the panels 2124 are in place the top end parts of the. top panel will extend into the side grooves 20 of the ridge strip and the top end parts of the bottom panels will extend into the grooves 27 in the sides of the combination or eaves strips 19. 3

Associated with each pair of glazing strips is a cap strip 35 which includes a horithe cap strip to pass, after which the flanges of the glazing strips engage the flanges" of the cap strip to hold them in place upon the glazing bars. The top ends of the cap'strips extend into the grooves of the ridge strip 20 and the combination or eaves strips 19'respectively whilethe tail or outer ends 38 of the cap strips are bent about the flanges 18 19 of the eaves strips to secure the outer ends of the cap strips in place. cap strips prevent any rain, snow or dust from passing in between the glazing strips, and the side flanges of the cap strips act to prevent any rain fromblowing or seeping in between theglazing strips and panels. The ends of the bottom part of the glazing strips are cut away as shown in Figs. 1 and4 so that such water of condensation as drips from the margins of the panels and falls in between the side members of the strips, is discharged from the lower outer ends thereof and passes through the openings 18 19 of the eaves strips to be discharged upon the outside of the skylight. The webs 31 and flanges 33 of the strips also provide gutters which discharge at the lower ends of the strip, such water as they may catch. 7

The improved glazing bar provides a water tight seal or connection at the adjacent margins of the panels without the aid of putty or like material. They are made of sheet metal and therefore they decrease the weight which the skylight structure must sustain, and may be made at a less cost than Thus the the rolled glazing bars now in use. No extraneous fastening means, such as bolts and rivets, are used in the assembly, consequentdefine a longitudinally extending slot along one side of said channel like member, adapted to receive the marginal part of a skylight panel, said member being capable of a lateral rocking movement about its bottom edge from an upright to an inclined position under the weight of the panel to cause the parts thereof defining the slot to clamp upon the marginal part of the panel.

2. A glazing bar comprising two chan nel-like members, each having side wall parts arranged to define longitudinally extending slots along opposite sides of said channel like members, adapted to receive the marginal parts of adjacent panels of a skylight, said members being capable of a lateral rocking movement away from each other about their bottom edges from an upright to an inclined position under the weight of the panels to cause the parts defining the slots to clamp upon said marginal parts thereof of the panels.

3. The combination with a glazing bar comprising two channel-like members, each having side wall parts arranged to define longitudinally extending slots along opposite sides of said channel like members, adapted to receive the marginal parts of adjacent panels of a skylight, said members. being capable of a lateral rocking movement away from each other about their bottom edges from an upright to an inclined position under the weight of the panels to cause the parts thereof defining the slots to clamp upon said marginal parts of the panels, and a cap strip engaging the top parts of both 'of said members and covering the space therebetween.

l. In combination with a glazing bar comprising two channel-like members, each having side wall parts of different heights, the higher side wall part of one channel like member having a top web which overhangs and is spaced from the top edge of the other side wall part to define longitudinally extending slots along opposite sides of said channel like members, each web terminating in an upturned flange, the said slots being adapted to receive the marginal parts of adjacent panels of a skylight, both of said channel like members being capable of a lateral rocking movement away from each other about their bottom edges under the weight of the panels to cause the parts thereof defining the slots to clamp upon the said marginal parts of the panels, and a cap strip having a web and depending side flanges, the

side wall parts of different heights which diverge outwardly from each other from their bottom margins, the marginal top part of the side wall part of greater height being bent to overhang but being spaced from the edge of the side wall part of lesser height to provide a longitudinally extending slot along one side of the glazing bar strip adapted to receive the marginal partof a skylight panel.

6. A glazing bar strip comprising two side wall parts which diverge outwardly from each other from their bottom margins, the marginal top part of said wall part of greater height being bent at substantially a right angle to form a web which overhangs but is spaced from the edge of the said side wall part of lesser height to provide a longitudinally extending slot along one side of the glazing bar strip adapted to receive the marginal part of a skylight panel, said web terminating in an upturned flange which is arranged in substantially the plane of one of said side wall parts of the glazing strip.

In testimony that I claim the foregoing as my invention, I afiix my signature in the presence of two witnesses, this 3rd day of June, A. D. 1921;

JOSEPH SYLVAN.
