UNITED STATES PATENT OF F ICE.
JACOB JACOBS, OF BROOKLYN, NEW YORK.
VAULT-LIGHT.
Specification of Letters Patent.
Patented July 2, 1907.
Application filed April 13, 1906. Serial No. 311,575.
To all whom it may concern:
, itfiBe it known that I, JACOB .IAcoBs, of Brooklyn, in
taken on the lines 22 and 33 of Fig. -l.
The object of my invention has been to provide a vault light which shall be of low cost, and, at the same time, shall protect the glasses from injury owing to the contraction of the cement, and to such ends my invention consists in the vault light hereinafter specified:
In carrying my invention into practice, I provide a casting consisting of a series of boxes A, that are connected by bars or an open-work or web B of any desired construction. The boxes preferably have a shoulder or flange upon which the glass 0 is adapted to rest. The main portion of the glass above its lower surface is preferably smaller than the boxes, and the space between the glass and the boxes is filled with a yielding cement D. In order to give the cement a good hold upon the glass, the glass may be provided with horizontal grooves, if desired. I
The web B connecting the boxes is as stated of openwork of any desired construction, and preferably does not extend to the top of the boxes. Buttons or plugs E of non-slipping material, and of any desired construction, are preferably seated upon the web B. The spaces between the boxes and the openings through the Web, are filled with cement, and the cement is preferably extended below the level of the boxes, as illustrated 'in Figs. 2 and 3; so that the web is preferably entirely embedded in the concrete.
If desired, tension rods F may be laid on the lenses between the boxes before the concrete is put in place.
As the glasses are inclosed within the metal boxes A, the contraction of the cement, which makes up the body of the vault light, cannot crack the glasses. They are well protected as if no cement were present. When weight is put on my vault light, the lattice work, crosspieces or separated bars B, connecting the boxes A, are subjected to tension and thus constitute tension members, and the concrete above them is subjected to compression. A very strong vault light is thus produced, although the casting for the purpose is much lighter and cheaper than would be if no cement were used. A con- .venient support for the non-slipping buttons or plugs,
is afforded.
My vault light combines the advantages of a vault light consisting of an iron tile having glasses seated in it with the cheapness of a reinforced concrete vault light. I
I claim: I
1. A vault light comprising a series of boxes, glasses mounted in said boxes, open work cross-pieces connecting said boxes in the lower portion of the structure and constituting tension members, and a cement-filling between said boxes and inclosing said cross-pieces.
2. A vault light comprising a casting, consisting of boxes connected by separated bars in the lower portion of the structure and constituting tension members, glasses mounted in said boxes, and a cement filling between said boxes.
In testimony that I claim the foregoing I have here unto set my hand.
' JACOB JACOBS.
