GLAZING SYSTEM.

Specification of Letters Patent.

Patented May 10, 1921.

Application filed March as, 1919. Serial ire/285,296.

/ This invention relates to glazing systems of the kind in which'the sheets of glass are retained in position on a reinforced concrete glazing bar without the use of putty or the like and the said invention has for its object to provide-improved means for holding the sheets of glass in position.

According to this invent on tliesheetsof glass are retained in position against a reinforced concrete glazing bar hav ng two upper reinforcing members by retaining or securing means adapted to engage metal oli is embedded in the glazing bar and suitably connected to the said reinforcing mein hers. Each sheet of glass is preferably retained in position against twp separate and independent bearing surfaces, the said bearing surfaces being supported by the glazing bar. The retaining or securing means comprises a screw, bolt or equivalent passed through. a metal washer and a weather resistii'ig washer on the upper faces oi the glass sheets and adapted to engage a metal clip bedded in the glazing bar and connected. to the two upper reinforcing incinb'ers thereof, a longitudinally disposed strip of bituminous felt or other weather l'8S1Sting packing being interposed between the lower faces of the glass sheets and the upperface of the glazing bar. The glazing bar is provided with a centrally arranged plane upper surface adapted to support the flat strip of weather resisting packing such as bituminous felt or other material, a channel or gutter and a recess on each side thereof, the said recess being adapted to receive asbestos or like packing material. If de'- sired the centrally arranged plane upper surface of the glazing bar may be extended upwardly so as to be flush or approximately flush with the {upper faces of the glass sheets.

In order that the invention may be clearly understood, reference is made to the accompanying drawings whereon Figurel shows a vertical section of a construction n accord ance with the present invention, Fig. 52%

shows a vertical section of a modified con,

struction also in accordance with the. pres ent invention.

3, 4 and 5 are respectively a side view an end view, and a cross sectionof a modified construction of the glazing .bar and the retaining means shown in Fig. 1. Referring to Fig. 1 of the drawings, lie a concrete glazing bar having two upper reinforcing members 2, 3 and a lower reinforcing member 4: of iron, steelor other face of the clip is flush or approximately.

flush with the plane face 5 of the concrete glazing bar.

The clip 13 is formed or provided with two downwardly extending prongs lfi, 16 the ends of which are bent, or twisted around the upper reinforcing members 2, 3

The upper face of the of the concrete glazing bar, the lower re- 1 inforcing member t being suitably connected. as by stirrups 17 to the members 2, 3. Thev uppe part of the glazing bar and centrally thereof, is formed with a hole 18 which is intended to receive'the end of a set screw 19, bolt or equivalent, the said set screw engaging the tapped hole in the clip 13 and thus binding the sheets of glass 20, Elbetween the asbestos packings 11, 12, bituminous felt strip 6 and a. bituminous felt washer 22 overlying the glass sheets. 23 is a metallic washer placed between the head of the set screw 19 and the washer 22.

In the construction shown in Fig. 2 the central portion of the reinforced concrete glazing bar is extended upward so that the plane face 5 may be flush or approximately flush with the upper faces of the glass sheets, the use of the longitudinally disposed bitumastic felt strip 6 shown in Fig. 1 being thereby obviated and the bituminous felt 35, 36 of th is cast or mol 21 of glass in position is or are made of asphalt, a mixture of asphalt and tar or similar material or concrete, compressed paper-pulp, imitation marble or stone or other suitable material reinforced longitudinally or vertically with'single wires or with two or more stranded wires as shown at 25. I cap or cover plate may be formed as a circular, square, rectangular or oblong plate and may be in lengths or sections. In a convenient form and as shown more ticularly in Figs. 3 and 5, the asphalt plate 24 is of any suitable length and may be provided with a portion of suitable shape projecting from the lower face of the cap 24. The metal wires 25, 26 or stranded metal wires are embedded in the asphalt at suitable distances apart, such wires being, if so desired, but not essentially interconnected by metallic or other suitable bindin material 27 shown dotted in Fig. 5. If deslightly below the said surface. The lengths or strips of asphalt 24 are secured to the glazing bar 1 preferably by screws 30 adaptec to engagenuts 3l'embe'dded in the glazing bar 1 and cast or molded therewith. A

washer 32 or washers of any suitable material may be interposed between the head of each screw 30 and the'length 24 or strip of reinforced asphalt. 7

At, suitable intervals along each inclined side of the lazing bar, recesses 33, 34 are provided, t e recesses being preferably formed in the lazin bar 1 when the latter did. he recesses 33, 34 may of any suitable depth, the characteristic feature of the recesses being that the faces e recesses 33, 34 against which the brackets 37, 38 abut are vertical so as to avoid'the use of angled or set-back brackets or tapered distance or filling pieces between the brackets and the glazing bar. At its lower end each recess may be flush with tie lower corresponding edge of the bar shown more particularly in F ig. 5 and the recesses may be longer as shown in Fig. 3, respective brackets so as to allow for adjustment of the brackets relative to the bolt holes 39 when securing the brackets and glazing bar 1 to the purlins 40 or equivalent. A plurality of bolt holes may be provided in the glazing bar 1. at each recess to allow for adjustment of the bracket. Each of the brackets 33, 34 may be secured by a separate bolt and nut but it is pre ferred that opposed brackets as secured by the same bolt 41 and nut 42.

' laim is:

1. T 1e combination of a reinforced glazing bar, of glass sheets supported thereon, and means forming a fixed part of said bar and'secured to the reinforce member thereof to retain the glass sheets in position.

In combination, a reinforced concrete glazing bar, having spaced independent bearing surfaces for each sheet of glass, 2- member embedded in said bar and connected h the reinforc ng means thereof, cover cent glass c and threaded into said member.

The combination with a reinforced concrete glazing bar, having spaced bearing surfaces to support glass sheets, a member embedded in said bar and tied to the reinforce means thereof, cover plates to overlie the glass sheets and bridge the joint between them and a bolt passed through said cover plates between the glass sheets and threaded into said member to secure the glass sheets in position.

In testimony whereof I have hereunto signed my name.
