UNITED STATES PATENT OFFICE.

FRANK RHIND, OF BROOKLYN, NEW YORK.

LAMP- BASE.

SPECIFICATION forming part of Letters Patent No. 248,504, dated October 18, 1881. Application filed August 10, 1881. (Model.)

To all whom t may concern:

Be it known that I, FRANK RHIND, of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Lamp-Bases, and I do hereby 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 pertains to make and use it, reference being had to the accompanying drawings, which form part of this specication.

My invention relates to an improvement in lamp-bases; and itconsists in making the base out of clay, which is first pressed into molds, baked, and then japanned, as will be more fully described hereinafter.

The object of my invention is not only to substitute a lighter and a cheaper material for the bases of lamps, but to produce a base from which the japan or coloring material cannot be chipped oi', as is the case with iron.

Figure 1 is a perspective of one of my bases by itself. Fig. 2 is a vertical section ofthe saine, showingl the base-ring of the standard in position upon it.

Heretoforethe bases forla m p-standards have been made of iron, which have rst to be cast and then polished olf, so asto receive the japan. As the iron is not porous, the japan merely adheres to the outer surface, and is very readily chipped and broken off, so as to deface the appearance ofthe lamp to a very great degree.

rlo form my base I take clay of any suitable kind, which is first pressed in a mold, baked, and then japanned. As the clay is very porous the japan is absorbed by itto such a degree that it is impossible to chip any of the japan 0E without breaking the base itself.

Laying aside thc fact that an iron base always rusts where it is leftunprotected, or where the japan is chipped off ofit, a base made from clay is not only lighter and cheaper, but is equally as serviceable, and cannot have the japan chipped off, as is always the case where the base is made ot' iron. Y

Through the center of the base, which is formed ot' clay, is made a suitable opening, B, for the standard -rod to pass through, and around this hole is made a suitable recess or depression, I), in which the lower ring, F, of the standard tits. This ring F is stamped up from any light sheet metal, and is placed upon the top of the base in the recess prepared for it, and then thc standard is placed upon this ring and clamped in position in the usual manner.

Having thus described my invention, I claim- As a new article ot' manufacture, a base for lamp standards, which is made of clay that is molded into suitable shape, baked, and then l japunned, substantially as set forth.

2. A lamp-base made of clay or other porous material which will absorb the japan to such a degree that the japan cannot be chipped oli' Without breaking the base, substantially as described.

In testimony whereofI affix my signature in presence of two witnesses.

FRANK RHIND.
