Application filed August 3, 1917. Serial No. 184,303.

To all whom it may concern:

Be it known that I, FREDERICK L. KEP- PLER, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Condensation-Gutters for Skylights, of which the following is a Specification.

My invention relates to improvements in condensation gutters for sky-lights and has for one object to provide in connection with a sky-light construction a new and improved form of condensation gutter and drainage system whereby the gutter itself will be insulated from the outside cold thus preventing the formation on the gutter itself. Another object of my invention is to provide a simplified condensation gutter wherein the minimum obstruction of light will be permitted. Other objects of my invention time to time in the specification.

My invention is illustrated more or less diagrammatically in the accompanying drawing, wherein- Figure 1 is a section through a sky light;

Fig. 2 is a part plan view;

Fig. 3 is a section on the line 3-3 of Fig. 2;

Fig. 4 is a section on Fig. 3.

Like parts are indicated by like characters in all the figures.

A is a building wall. Mounted upon it is a roof girder A Supported from the wall by any suitable means not here shown is a girder A A are angle or bench plates mounted on the girders A and A .A is a glass concrete sky light'panel or structure supported at its edges on the girder supported plates A as indicated. This structure forms the roof itself. Its surface is exposed to the atmospheric conditions outside the building, its inner surface to atmospheric conditions inside the building. In col weather it will be exceedingly cold and the moist air inside coming in contact with the cold inner surface will condense. It is this condensation which my invention provides for carrying'away.

The sky light structure is made up as 1ndicated of a series of separate glass tiles B, B which are provided with corrugated upper surfaces B as indicated arranged ad acent one another to contain a concrete or the line H of plastic filling material B embedded in which is'a series of metallic reinforcing bars so that when the concrete has set the tiles are held together as a single unitary translucent structure. Each tile has four downwardly depending sharp edged walls as indicated. Two of them, B B are parallel with the upper surface of the tile. The other two, 13*, B are downwardly and outwardly inclined so that any water of condensation developing on the surface will run down to the walls 13* and thence follow the small portion in Fig. 3 to the lowest point of the tile where the water will drip oif. The water which thus drips off will be caught in the gutters 13 ,13 which conform to the slope of the roof and discharge into a main gutter These gutters B, B are arranged parallel and owing to the peculiar shape of the lower walls of the glass tile sections no cross gutters are needed, the water being conveyed from each tile to the longitudinal gutters on either side thereof.

Thesegutters are supported a short dis tance below the sky light far enough down so that they are insulated by an air cushion from the sky light itself, and thus protected from the extremes of temperature.

The upper ends of the gutters B are supported on-the brackets G resting upon the members A and lying beneath the concrete filler which surrounds the outer portion of the sky light. They are thus not directly exposed to the outside atmosphere but insulated by the concrete which forms a considerable insulation and which in view of the small size of the connecting member does not result in any material cooling of the gutter itself. The same arrangement prevails at the lower end where a bracket C supports the gutter resting on the support beneath the sky light structure. This insulating of the concrete is assisted by a thin layer of any suitable insulating material C This insulating layer may be made of rubber cement, asphalt, fiber board, cork and the like, but rubber cement is particularly suitable for the purpose. This may or may not be used as the case may be depending on the extremes to be encountered and other conditions. C C are elastic cement expansion joints provided between adjacent sky light sections whereby they may be permitted to expand and contract without danger of springing a leak or the like.

It will be evident that while I have shown in my drawings an operative device, still many changes might be made both in size, shape and arrangement of parts without departing materially from the spirit of my invention and I wish, therefore, that my drawings be regarded as in a sense diagrammatic.

D is a gutter supporting angle iron comprising an angle having one flange extending down across in front of the edge of the member A the other flange resting upon that member. The'skylight structure itself rests upon such member being insulated from it as at C The gutter itself is mounted upon the flange being insulated from it at D the two parts being bolted in position. By this arrangement .of course, the

flange supporting the gutter is insulated from the outside and the gutter itself is insulated from the flange so that there is a minimum tendency for any cooling of the gutter itself which would cause it to catch condensation.

The use and operation of my invention are as follows z- With the structure in place, condensation will as indicated form on the under surfaces of the tile. It is a wellknown fact that the water of'condensation will not let go of the surface until it reaches its lowest point'and thus the water will travel along the inclined tile surfaces and be discharged along the lowest straight edge of the tile where it will be caught by the sky light and which being insulated from the outside air areof substantially the same temperature as the room and thus do gutters beneath not give rise to any condensation themselves.

This water is carried off by these series of gutters and discharged in any suitable manner. In view of the fact that the tiles are so shaped that all the water discharged is on two opposed sides of the tile, it will be understood that there is no necessity for any cross gutters except at the lower edge to join the inclined lateral gutters together. These inclined gutters being very narrow since the point discharging them is localized by the shape of the tile, will afford a minimum of obstruction to the light coming in through the sky light. The downwardly inclined condensation surfaces as shown lead the water of condensation to the acute drip edges and the water then runs along these acute edges down along the uninclined drip edges where the lowest point is reached and where the water finally drops off into the drip gutters.

I claim: 1. A glass tile for sky lights and the like having formed on its under side a plurality of downwardly inclined condensation surfaces terminating in a plurality of conuected acute drip'edges depending. below mounted thereon, tile being shaped to catch the condensation said tion drip edges,

the point of support of the tile, some of said edges being inclined meet the other edges.

2. A glass tile for skylights and the like downwardly to consisting of a relatively thin central por- 'tion, a thickened tile base portion surroundtion, a thickened tile base portion surrounding it, and a plurality 'drip edges depending below't'he point of "of connected acute support of the tile forming the inner side of sald base portion.

4. A glass tile for sky lights and the like having formed on its under side a plurality of downwardly inclined condensation surfaces terminating in' a plurality of :con- 'nected acute drip edges, some of said edges being parallel with the top of thetile and others being inclined downwardly to meet them. v

5. A sky light structure comprising a supporting framework, a glass tile structure the undersides' of the'glass to concentrate the drip of condensation along parallel lines and gutters arranged beneath such lines adapted gutters being out of contact with the tiles and the'mem- 'bers directly supporting them.
