6 Claims. (Cl. 108--16) This invention relates to skylight construction Skylights are mounted on Structural framing and has for its object to provide a construction members which may be of different formations which is simple in parts and more efficient in such as angle bars, channel members, I-beams use than those heretofore proposed. etc. but in Fig. 1 there is shown for convenience With these and other objects in view the inan angle bar I5 which is provided, at spaced in- 5 vention resides in novel details of construction tervals in the horizontal flange I6 thereof, with and combinations of parts as will be described a plurality of preformed round apertures such more fully hereinafter and particularly pointed as Il for a purpose presently to appear, and the out in the claims. v body portion 2 of the gutter plate is provided l@ Referring to the accompanying drawing formwith similar apertures such as I9 adapted to reg- '10 ing a part of this specification and in which like ister with the apertures I'I when the parts are numerals designate like parts in all the views,- assembled.

A bolt hard metal such as steel and provided on its l is threaded at its upper end to receive thereon shank portion with a screw thread of relatively 35 a cap nut 8, and near its lower end there is progreat pitch so that when said screw is driven, the vided a substantially conical portion 9 whose threads thereof will bite into the walls of the lower edge constitutes a shoulder adapted to rest apertures I8 `and I1 and become tightly engaged against the upper surface of the main body portherewith to hold the parts 2, I9 and I6 in rigid 40 tion2 of the gutter plate, the extreme lower porsecurement.

To senting a minimum of protuberance above the 4 5 f prevent rotation of this bolt with reference to gutter plate. the gutter plate the lower end of the bolt is made From what has been above described it will be of square or yother polygonal shape as indicated seen thatv the anchor bolt 1 is rigidly secured to at Il in Figa-and both the gutter plate and the the gutter plate, and that the gutter plate is rig- 0 washer I0 are provided with correspondingly idly secured tothe angle bar or other structural 50 formed apertures such as indicated at I2 for supporting unit by the drive screws 22, with a engagement therewith. These bolts 1 are spaced strip I9 of asphaltic felt or other insulating maat desired intervals along the length of the gutter terial interposed between said plate and said bar. platesand preferably are secured thereto at the` Further, it will be understood that the polygonal 5 5 factory prior to the assemblage of the skylight. t between the anchor bolt and the gutter plate 55 preventsturning movement of said bolt when the cap nut 8 is applied or removed, and the shoulder portion 9 of said bolt together with the washer l0 makes possible a substantially waterproof joint by virtue of the pressure exerted when burring the end of the bolt over the washer. In other words the burring pressure is great enough to clamp the washer, the main body portion of the gutter plate, and the shoinder. of the bolt tightly in surface contact with each other, while at the same time causing a lateral expansion of the metal of the shank Il of the bolt into tight engagement with the inner surfaces of the polygonal apertures of said washer and said gutter plate. Y

In the further assemblage of the skylight, and after the gutter plate has been secured to the supporting structural member such as the angle bar l5, there is provided another strip 25 of asphaltic felt or other suitable insulating material having preformed apertures such as 26 adapted to register with and receive therein the anchor bolts. Preferably these apertures are formed of a diameter substantially equal to that rof the upper portion of said bolts so that, when the strip 25 is pressed against the upper surface of the gutter plate, the substantially conical shoulder portion 9 of the bolts will tightly it and close said apertures and thereby form a substantial seal preventing passage of moisture or air. 'I'his strip serves as a seat for the skylight glasses and is shown as having a width substantially equal to the width of the main body portion of the gutter plate, but obviously it could b e wider if desired.

Next above the strip 25 is positioned a plurality of spacers generally identied by the numeral 21 shown in section in Figs. l and 2 and shown in perspective view in Fig. 10. Each spacer is made of rubber or other compressible material which is impervious to water, and is centrally apertured to receive the anchor bolt, and is of a width as seen in Fig. l to substantially ll the space between the opposing edges of the glasses 28 and 29 of the skylight, the purpose of the spacers being to prevent said glasses from contacting the anchor bolts yet Ypermitting relative expansion and contraction of the metallic and glass members under changes of temperature, without Vinjury to either. The spacers can ,be individual units as illustrated or there may be provided a single separator strip of a length suliicient` to receive two or more bolts therethrough but it has been found most desirable to provide the individual units, one for each anchor bolt, due to ease of handling as well as minimum of material. The underside of the spacer unit 21 may be provided witha cut away portion indicated at 30 for various purposes such as saving of material, providing a recess to receive therein any upwardly displaced portion of the Weatherproofstrip 25 occasioned by theV conical Vshoulder of the anchor bolt, to reduce the thickness of the central portion of the unit to permit a more ready expansion of the material of said unit when pressure is applied to secure the glasses 28 and 29 in position, etc. Y

With the spacers such as 21 applied over the anchor bolts, the glasses 28 and 29 are laid in position as shown to rest upon the strip 25 with the space between their opposed edges occupied by said spacers, and then a third strip 33 of asphaltic felt or other suitable weather-resisting material, having preformed apertures therein, is applied over the bolts on top of the glasses. A sheet metal cap member generally indicated by the numeral 34, also having preformed apertures therein, is then applied over the bolts and secured under tension by the cap nut 8 against the strip 33 to complete the skylight assemblage. The sheet metal cap is substantially of the form shown in Figs. l and 5, having a main body portion with downwardly divergent skirt portions Whose lower edges are outturned to provide'flanges disposed in Va plane substantially parallel to the plane of the main body portion, said anges adapted to rest upon the uppermost felt strip 33. By this construction a slight springiness or yieldability is permitted when the cap nut 8 is screwed down tightly against the upper surface of the main body portion, thereby rendering possible a tight joint between the flanges and said strip.

In Fig. there is shown double glazing employed in the skylight construction, that is to say there are provided a plurality of panes of glasses disposed in a common planeV constituting the upper glazing, as well 4as a plurality of panes of glasses disposed in another and lower common plane constituting the lower glazing. All of the parts here illustrated above the plane of the lower surfaces of the upper glasses, as well as all of the parts shown below the plane of the lower surfaces of the lower glasses, are substantially the same as those described and shown with reference to Fig. l and( consequently need no further description. Therefore the only parts requiring specific mention here aremthose Vlying between said planes.

The purposeof double glazing is to provide an insulating air space between the panes as well understood, and to make possible the utilization of glass panes of different kinds, qualities and other characteristics producing diierent resulting eifects Y onY thelight rays transmitted therethrough. Consequently theupper andlower glazings are subject to different temperatures namely, the former to outside and the latter to inside temperatures the `difference between which may be considerable, and thereforen provision is made to take `care of the air pressure in the space between these glazings.V 'Io` this 'end strips 55 and 56 of suitable cushioning and/or weather proofing or insulatingV material are placed respectively above the lower glazing and beneath the'upper glazing, with a Wood separator 51 and a spring `brass cushion stripV or leaf spring 58 interposed between said. insulating strips as shown, all of these members provided with apertures to receive the anchor bolt therethrough. As the pressure varies between vthe upper and lower glazing, the spring stripV 58 Will yield accordingly, and permit relative movement of one glazing with respect to the other. The members 55, 56, 51 `and 58 are each preferably continuous thereby making a perfect closure in Vthe skylight structure, although it is obvious that each may be made of a plurality'of substantially lengthwise adjoining units spanning two or more anchor bolts.

It is obvious that those skilled in the art may vary the details of construction as well vas the arrangementsof parts without departing from the spirit of this invention and therefore I do notV wish to be limited to the exact foregoing disclosure except as may be demanded by the claims.

What is claimed is: p

l'.
