SKYLIGHT.

JOSEPH F. FORDERER, OF SAN FRANCISCO, OALIFORFIA SKYLIGHT.

EPECIFICATION forming part of Letters Patent No. 334,650, dated January 19, 1886. Application filed March 29,1.84. 7 Serial No. 126,086. (No ml (lelJ- To all whom/it Wtay concern.-

Be it known that I, JosEPH F. FORDERER, of the city and county of San Francisco, State of California, have invented an Improvement in Skylights; and I hereby declare thefollowing to be a full, clear, and exact description of the same.

My invention relates to certain improvements in skylights; and it consists in a novel construction of the channeled bars by which the glass is held, air-passages for ventilating purposes and to equalize the temperature, stops for retaining the glass in place, and in certain details of construction, which will be more fully explained by reference to the accompanying drawings, in which Figure 1 is a view of a skylight. Fig. 2 is a longitudinal vertical section taken through one of the bars. Fig. 3 is a transverse sectio showing a modified form of the bar.

Skylight-bars are commonly made hollow, and have been made in two or more parts namely, the body, the cap, and the gutter which are riveted or otherwise secured together. The lower part of the bar comprising the body and the gutter being fixed, the glass is then placed so as to rest upon the shoulders of the bar, after which the cap is put on and secured.

In my skylight the bar is composed of a single sheet of metal, formed by suitable machinery, and comprises the cap A, and the body B, having a channel between itself and the cap to receive the glass, and a gutter, 0, formed by turning the two edges of the sheet outwardly, so that this gutter will receive moisture that may drip from the interior of the glass and carry it away. With my construction it is necessary to leave the upper and lower ends of the channels between the body and the cap open, so that the glass may be slipped into place from one end or the other, being bedded and fixed with asuitable cement or putty. In some cases the skylight may be so near to a structure at either the upper or lower edge that the glass must be slipped in from the opposite edge, and this is provided for by the removable stops or caps E and F, which are screwed or otherwise secured upon the frame-work of the shylight at the lower and upper ends respectively, these caps serving to cover and protect the open ends of the bars also. The foul air, which collects inside sides of the body B of the bar, and it may pass out through openings I, made through the frame at the upper end; The stop F, which retains the upper edge of the glass, and overlaps it to prevent the entrance of wet or moisture atthat point, has a plate or flange, F, extending down over the outside of the Ventilator-frame, and protecting the upper ends of the open skylight-bars, so as to form a sort of a chamber between the openings I and the lower edge of this plate F, into which the air from the hollow bar first passes, thence escaping beneath the edge of the flange, as shown in Fig. 2, the flange being bent outward at this lower edge, so as to leave an open channel or space beneath it. The lower ends of the skylight-bars B are also connected by openings with the exterior of the frame, and they are protected by hollow-arched caps H, which extend downward, so as to prevent the ingress of wet, and at the same time they allow air to enter the bars and to pass through them freely, escaping at the upper ends, as before described, thus supplying fresh air to equalize the temperature, which would otherwise be very high in the space beneath the skylight. This also reduces the amount of condensation on the glass and the resulting water to be carried away by the gutters.

In the usual formation of these skylightframes they are made of separate pieces, as before stated, and the free edges extend upward, being afterward covered by a separate cap. When the skylight is large,jthe weight of itself and the glass causes the bars to bend downward, and this is not resisted by the thin edges of metal which project upward, as the tendency is to bend and buckle these edges when the weight comes upon the bar, allowing the whole bar to give way.

In my construction the upper part of the bar or cap is formed by bending the center of the metal sheet into a semi-cylindrical diamond or other shape, contracting it to form a neck where the edges of the glass approach each other, expanding it again beneath to form shoulders,upon which the glass rests, and then continuing it downward contracting it again, so that the sides come together, after which theventilator, beneath the glass,passes through openingsor slots-G, which are made in the the lower edges are bent outward and turned up to form the gutter. All the strain of compression in this bar comes upon the upper con tinuous portionof the metal, the shape of which resists the tendency to compression at this point, while the tension or pulling-strain upon the lower part of the bar is much better resisted by that portion forming the gutter than the strain of compression would be resisted by the edges when turned upward.

The whole construction forms a very strong and perfect skylight-bar with ample means for ventilation and the equalizing of the temperature.

Having thus described my invention, what I I claim as new, and desire to secure by Letters Patent, is-

1. In a skylight, the frame having the parallel bars formed of single sheets of metahwith permanent channels between the body and head,'in combination with stops or plates E and F,secured across the ends of the bars, sub stantially as herein described.

2. In a skylight, the frame having the hollow bars formed in a single piece and perfo rated upon their sides, in combination with a cap. F, having a flange, F, forming an airchannel, substantially as herein described.

3. In a skylight, the frame with the hollow perforated bars formed in a single piece, having their upper and lower ends open, and the caps E and F, extending across these ends, in combination with the hollow arched caps or ducts H, and the perforations I, and the flange F, substantially as herein described.

4. In combination with a skylight-frame, as herein described, the stop F, provided with a flange, F, forming an air-channel, substantially as herein described.

5. A skylight-bar formed of asheet of metal folded at its center, so as to form a deep and open head or upper portion, and a similar body with spaces or channels for the reception of the glass, formed by the vertical rib extending between the head and body, the lower edges of the sheet being turned outward and upward to form gutters at the bottom and below the plane of the glass and separate from it.

In witness whereof I have hereunto set my hand.
