l To all whom it may concern: I

Be it known that I, JOHANNES DEGENHARDT, manufacturer and proprietor of the firm of Fr.

Basse/Nacht., a subject of the German Em# Y.peror/,Mand formerly a resident 'of 5 Wilhelmstrasse, Cassel, Germany, and now residing at 433 Waldstrasse, Berlin, Germany, have invented new and useful Improvements in Skylights, of which 'the following is a specification.` y

This invention relates to improvements in bars usedffor the support of panes of glass constituting the roofs of grec nh ousesvand other glass-covered buildings and also to improvements in the manner of glazing or fixing together the panes of glass used, the object of the invention being to prevent the sweating of vthe bars and to collectin the bars the water which eventualljv trickles through the panes, which bars serve at the same time as channels for this water. Y e p VA further object of the invention is to keep the weight 'of persons going on the roof for repairing or cleaning oi the panes and to transfer it directly to the supporting-bars, thus preventing the breakage of the glass panes.

In the accompanying drawings, Figure 1 shows a part of the improved bar in a perspective view. Fig.` 2 is a perspective view of the bar with the window-panes inserted. Fig. 3 represents a vertical transverse section in a plane through the spring surrounding one of the uprights which extends between the panes of glass.

The supporting-bar 1 consists of a U-shaped iron which is open at the upper end. Into this supporting-bar 1 brackets 2, of 1-shaped iron, are inserted at a suitable distance from each other, with the open tend turned down. The brackets 2 are fixed in position by` means of screws or rivets 3 or in any other suitable manner. On the upper surface of the brackets 2 two grooves 4 and 5 'are provided, one at each end. A On the bridges 6 of the brackets 2, formed by that part of the brackets which is 'situated between the grooves 115x 5, a fiat iron bar y7- is placed, which extends over the whole length of. the supporting-bar 1. On this fiat iron bar 7 a felt strip 8 is placed,v on which the windowpnes 9. 10 are laid.' l A second felt strip 11 is placed over the adjacent edges of the window-` panes 910, which felt'strip 11 is coveredA by f neissuea'ran. 2, 1906.

la cap 12, of sheetv metal, lead, or any other I lsuitable material. r

The fiat iron bar` 7 as well asthe'felt strips 8 11, andthe cap 12 have holes for the passage of bolts 13, one of which is screwed into each o f the bridges 6, projecting a certain distance above the cap 12. The bolts 13 ,have a setoff on the upper end, which serves `as support for a ["l-iron 14, running parallel to the supporting-bar 1. position by means of screw-nuts 15, screwed to the upper ends of the bolts 13. Spiral springs 16 are coiled around the bolts 13, abutting against the upper surface of the cap 12 and against the lower surface of the'iron 14, whereby the ends of the window-panes 9 10 are tightly pressed against their seats.

The l-I-irons 14 server'as support for the planks to beplaced on the roof in case of re.rv

pair, thus receiving the weight of persons goling on the roof and transmitting this weight directly tothe bridges 6, brackets 2, and to the'supporting-bars 1 by means of the bolts 13, so that no strain is exerted on the glass panes. The glass panes have free play at their adjacent edges, and being elastically supy This iron 14 is secured in itsl 1 proved supporting-bars for panes of glass constituting the roofs of greenhouses and other glass-covered buildings is that theglass panes do not rest directly on the su pporting-bars 1, so that the hot or warm air from inside the building has access to all parts ot' the supporting-bars, which are thus prevented from sweating. The great disadvantage of the sweatwater which at present continually drops from the supporting-bars is thus entirely avoided.

Having fully described my invention, what I claim, and desire to secure by Letters Patent', is

1. A roof structure comprising supportingbars, means carried thereby for supporting the adjacent edges of glass panes, uprights extending from said bars between the panes, and bars supported by said uprights above the panes and parallel with the supporting-bars.

2. A root' structure comprising supportingbars, brackets supported by these bars at a suitable distance from each other, Vertical bolts projecting from these brackets, fiat iron bars connecting the brackets of one bar with each other, elastic strips on said iron bars serving as supports for the edges of the panes of glass, elastic strips covering the adjacent edges of the panes of glass, protecting-capsV tance from each other, vertical bolts projecting from these brackets, fiat iron bars connecting the brackets of one bar with each other, elastic Lstrips on said iron bars serving as supports for the edges of the panes of glass,

elastic strips covering the adjacent edges o1v the panes of glass, protecting-caps covering said elastic strips, spiral springs coiled around the vertical bolts pressing said caps and consequently the edges of the panes of glass firmly' on their seats, and bars resting on setofs on the upper ends of the bolts running parallel to the supporting-bars substantially as described and shown and for the purpose set forth.

4. Improved bars used for the support of panes of kglass constituting the roofs of greenhouses and other glass-covered buildings, cornprising in combination U-shaped iron bars, l-shaped brackets inserted into these bars-at a suitable distance from each other, two grooves in the upper surface of said brackets forming bridges between them, vertical bolts screwed into these bridges, fiat iron bars connecting the bridges of one bar with each other, felt strips on said iron bars serving as supports for the edges of the panes of glass, felt strips covering the adjacent edges of the panes ofglass, protecting-caps covering said felt strips, spiral springs coiled laround the vertical bolts pressing said caps and consequently the edges of the panes of glass firm-ly on their seats, and f l-shaped iron bars resting on set-ois on the upper ends of the bolts running parallel to the supporting-bars, substantially as described and shown and for the purpose set forth. 5. A root' structure comprising channelshaped supporting-bars, brackets having their ends turned down and fitted within the sides of the channel-shaped bars, said brackets being secured to the said bars, means for supporting the adjacent edges of glass panes, up-

rights'extending` between the panes, and bars supported by said uprights above the-panes and parallel with the supporting-bars.

In testimony whereof I have hereunto'set my hand in presence of two subscribing witnesses.

JOHANNES DEGENHARDT.
