(NoModel) I VAULT LIGHT.
No. 376,649. Patented Jan. 17, .1888.
v @Vitywwe UNITED STATES PATENT OFFICE.
JOHN CLAYTON HALDEMAN, OF PHILADELPHIA, PENNSYLVANIA.
VAULT- LIGHT.
SPECIFICATION forming part of Letters Patent No. 376,649, dated January 17,1888.
Application filed April 14, 1887.
To aZZ whom it may concern/r.
Be it known that I, JOHN CLAYTON HALDE- MAN, a citizen of the United States,-residing in the city and county of Philadelphia, State ofPennsylvania, have invented a new and useful Improvement in Vault-Lights, which improvement is fully set forth in the following specification and accompanying drawings.
My invention relates to improvements in vault-lights; and to this end it consists in a novel form or forms of vault-lights, whereby the light is more extensively dispersed within the vault than has heretofore, so far as I am aware, been possible.
Figure 1 is a plan view of my improved vault-light. Fig. 2 is a cross-section of Fig. 1, taken on line m 00, showing, also, a part of the vault-door B in section and the retainingpacking D. Fig. 3 is a plan view of a modified form of my invention. Fig. 4 is a crosssection of Fig. 3, taken on line at at, similar in general respects to Fig. 2. 7
Similar letters of reference indicate corresponding parts in the several figures.
Referring to the drawings, A is the vaultlight, made of glass or other light-conducting medium, and having the usual rib, E, for retainingit in place in the vault-door.
O is a cone-shaped surface in the lower end of the light, the function of which will be explained hereinafter.
D is the usual packing material for retaining the light in place in the door.
Serial No. 234,856. (No model.)
It was also old to use a solid-glass light having its lower end cut off diagonally, so as to deflect the lightin one direction only. I do not, therefore, lay any claim to such features.
My invention differs from these in that it deflects or di'tluses the light in all directions and without the aid of extraneous devices.
I will now describe the mode of operation of my improved vault-light. It will be seen,on examination ofFig. 2, that the entering rays R R R pass into the light and encounter the prismatic surface O,whence they are reflected in all directions in reflected raysR It, as shown, the uncovered plain face a permitting their direct entrance into the vault. This inner'surface, C, may be covered with mercury or other reflecting material, if desired. Such a light I deem within the scope of my invention.
In Figs. 3 and 4. I have shown a modified form of my improved vault'light, in which the hollow surface is corrugated or. grooved, as clearly shown. With this arrangement I get a more uniform diffusion of light in all directions, as will be readily understood by those skilled in the art, the corrugations diffusing the light laterally as well as radially.
Having thus described my invention, what I claim as new, and-desire to secure by Letters Patent, is-
The vault -light A, having ribs E and a conoidal reflecting -surface, 0, on its under face, in combination with the vault-door B,
the said light A projecting below said door B, so that nearly the entire conoidal reflectingsurface is below the same and the peripheral face a is uncovered, substantially as and for the purpose set forth.
