I wish it understood, however, that preferably an electric lamp or a series of this is an example, merely, of many structhem if the article be large. In the drawtures commonly employed for architectural ings I show such an arrangement. 0 is a suitdecoration in which the invention may be able bracket or support, which may be atbeneficially employed-such, for instance, as tached in any suitable manner to any desired newel-posts, balustrades, columns, or pillars part of the structure by which a series of for supporting superstructures and the like. electric lamps cl (Z, suppliedv with circuit-wires A represents the base of the column; B B, e 0, are suitably supported. the shaft thereof; C, the capital, and D the The operation of the invention is as follows: table or top.

This In the manufacture of my articles I proceed as follows: I take solid crude rock as it comes from the quarry, of the kind known generically as gypsum, including the entire group of rock having the characteristics result is secured by reason of the property that rock of the gypsum family possesses, being of crystalline structure, of freely transmitting light through its substance, even though several inches in thickness. Thus it is possible under my invention to produce devices or structures for use architecturally of such strength that they are adapted to be used under circumstances in which they will be called upon to resist great strain and permanently carry heavy bodies.

I prefer to ventilate the structure by providing suitable blow-holes, as I call them, (shown at ffi) so that the heat may escape, and I also sometimes, especially if the article be very small, apply to its interior as well as exterior surface liquefied transparent wax, paraffin, or similar material which will penetrate the surface, and thus prevent dust and dirt from entering the structure of the rock, which would have a tendency to reduce the brilliancy of the illumination. I do not illustratethis in the drawings, because I do not apply so much of the paraflin or similar mate rial as will leave an appreciable coating on the surface, only so much as will be taken up by the stone as a filler for its grain. If so much were applied as to leave an appreciable coating on the surface, it would be readily scuffed up, scratched, and defaced with foreign matter being rubbed into it, so that instead of being any improvement it would be a decided detraction.

Of course suitable provision will be made for renewing theelectric lamps should renewal be needed. In the case shown free ac cess may be had to the interior of the column by simply lifting off the table D.

Articles made under my invention when illuminated throw off considerable light. L

They therefore may be used to illuminate the chamber or space in which they are located, producing most beautiful effects.

I claim- 1. As a new article of manufacture a hollow structure made from translucent rock, such as gypsum in its natural state, and means to illuminate the interior thereof.

2. As a new article of manufacture a hollow structure made from translucent rock, such as gypsum in its natural state, coated with translucent material, such as paraffin, and means to illuminate the interior thereof.

3. As a new article of manufacture a hollow structure made from translucent rock, such as gypsum in its natural state, means to illuminate the interior-thereof and means to ventilate the interior thereof.

In testimony whereof I. have signed my name to this specification in the presence of two subscribing witnesses.
