UNITED STATES I PATENT OFFICE.
JOHN T. PENNYOOOK, OF NE\V YORK, N. Y., ASSIGNOR TO THE ALPHA GLASS AND METAL COMPANY, OF NEV JERSEY.
SKYLIGHT.
SPECIFICATION forming part of Letters Patent No. 417,334, dated December 17, 1889.
Application filed April 12, 1889- Serial No. 307,013. (No model.)
To all whom it may concern:
Be it known that 1, JOHN T. PENNYCOOK, a citizen of Great Britain, residing at New York, in the county of New York and State of New 5 York, have invented certain new and useful Improvements in Protecting Glass; and 1 do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apto pertains to make and. use the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon, which form a part of this specification.
My invention has relation to means for protecting glass for roofs of greenhouses, depots, and the like from the injurious action of the elements, the fumes 0f deleterious gases such as sulphurous fumes from the smokestacks of engines; and the novelty consists in the construction, combination, and arrangement of the several protecting parts of the device, as will be hereinafter more fully described, and particularly pointed out in the claim.
The figure in the drawing is a cross-section of a roof girder or sash with the adjacent ends of two panes of glass resting thereon and the lead protecting-strips applied thereto.
A is a girder made of rolled or sheet steel 0 in a single piece. It is doubled back upon itself to form the double rib a, thence laterally in a curve outward and upward to a point I) on each side of the rib, thence back, following the parallel line, so as to form the flanges c c, and terminating at a point near the base of the rib a.
B is a sheet-lead strip bent over the rib a, down each side thereof, up under the flanges c a, back again upon itself, and up the sides 40 of the rib at, its free ends terminating at about the top of the rib.
The glass 0 is laid upon the flanges c c, as shown, and the strip of sheet-lead bent over the edge and top of the glass, as shown in 5 right-hand side of the rib, the strip on the left being in position ready to be bent down upon the glass. It will thus be observed that the lead strip where it comes in contact with the edge of the glass acts as a cushion or protector, and the end of the flange where the glass is supported, being somewhat elastic, forms a non-rigid rest for the glass as against downward pressure, and the lead strip lapping over the top of the glass sustains it against undue upward pressure-as, for instance, heavy winds under the roof in case of large railroad or wharf sheds,where the sides and ends of the sheds are open.
It will be observed that the portion 0' of the flange 0 holds the lead strip closely into position, and in the event of an upward strain on the glass said strain would come on the vertical portion I) of the lead strip, and as the flange portion 0 holds this in place it will beinipossible to dislodge it.
Of course it will be readily understood that the steel girderis formed into shape,with the exception of the portion 0', and the lead strip applied, and the whole passed between rollers to press the portion 0' into the position shown in the figure.
Having fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent of the United States,
The combination, with the girder made of rolled or sheet steel in a single piece doubled back upon itself to form the doublerib a, thence laterally in a curve outward and upward to JOHN T. PENNYCOOK.
