UNITED STATES CHARLES D.

MOODY, or ST. LOUIS, MISSOURI, ASSIGNOR or ONE-HALF HIS RIGHT T0' EDWIN A. SKEELE, OF SAME PLACE.

IMPROVEMENT lu wooDEN LAMES.

Specification forming part of Letters Patent No. 146,467, dated January 13, 1874; application filed March 14, 1873.

To all whom it may concerti Be it known that I, CHARLES l). MOODY, of the city and county of St. Louis, State of Missouri, have invented new and useful Improvements in Lamps, of which the following is a full, clear, and exact description, reference being had to the annexed drawing making part of this specification, and to the letters of refer.-

ence thereon marked.

Lamps usually have been made of glass an metallic Substances. Its extreme frangibility, however, renders glass unsafe to property and life, and, for permanent use, expensive. To

\ the use of metals lies the objection that, be-

cause of their heat-conductin g properties, they cannot, without an intricate and expensivev construction, be employed in the manufacture of lamps in which carbon-oil is burned, although Well Suited for lard and like oils.

. To obviate these difculties, and to obtain a lamp that can be readily and economically made with great beauty of design and nish, and in great variety of form, is the object of i my invention, whichconsists mainly in a lamp (its burner portion excepted) made of wood, with the oil-chamber thereof, to prevent 1eak age, saturated, or' coated, lined, or covered, on the inner or outer side, or on both inner and outer sides, with a substance or material that is impervious to carbon-oils.

In vthe accompanying drawing, A represents a lamp, which, in design, may be of any api in a lathe, from one or more pieces of wood. `The base a, stem al, and lower portion a2 of the body or oil-chamber of the lamp can be formed from one or more pieces, and the upper portion of the body a3 from another. When composed of two or more pieces, the parts are i joined in any suitable manner, and all joints that occur in the formation of the oil-chamber are rendered tight by any cement-like glue that is unaffected by the'oil burned. The burner B is attached in the ordinary manner to the part j a3. This construction may be modified by extending the lower portion a2 of the body of the lamp upward suiicie'ntly to bring its upper edge to about the level of the base of the burner, and by connecting` the collar b, in which the burner is screwed, directly with it. In this ,.event, the collar b, if necessary, can be extended and enlarged sufficiently to connect with the part a2. Another modification is to 'put together similar strips or pieces of wooden molding, prop# erly beveled at their ends, so as to form, when joined, a three or more sided formation. i An` other method, having reference more particularly to ornament, is to combine differentlycolored woods. .'lhis, when the lamp is made in the lathe, may be done by putting together two or more kinds of wood, arranged verti cally, horizontally, or inclined, and from the composite pieceforming the lamp. When arranged horizontally, the different pieces can be turned at different times, and afterward joined. A further modification is to construct the base or lower portion of the lamp of metal, f and combine with Such base a wooden oil-chamber or body. l

The advantage of this last-mentioned construction is that the base portion can, with little expense, be cast in any ornamental form, and, the oiLChamber or body of the lamp being readily and strongly made of a material that is a poor conductor of heat, the lamp is I do not wish, in this respect, to be limited to any one liquid or plastic substance or material, -or to any particular mode of application. Glue is preferably used, although there are other Well-known substances that are ef-v fectual in resisting the action of illuminating oils and fluids under the above-mentioned con- Y affected by moisture, the glue may have 1inseed-oil, or au equivalent, added to it in suitable proportion.

To iinish the lamp, a paint, varnish, or oil can,witl1 advantage, be applied to the-outside. This also serves in repelling moisture.

I am Well aware that lamps have been made partly of Wood, and also have been made with metal oil-chambers covered by or inclosed in a Wooden casing, but in such a Way that the oil did not and could not come in Contact With the Wood, nor did the Wood in any manner prevent the heat of the llame from being conducted to the oils Within the chamber ,and consequently I do not claim, broadly, the use of Wood in the manufacture of lamps under such conditions g nor do I claim there is any novelty in using a liquid or plastic material or substance to render Wooden vessels impervious to oils or like substances; but

What I claim as new', and desire to secure by Letters Patent, is

A lamp having its body or its body and base Wholly constructed of Wood, such body being, Y for the purpose of rendering it impervious to specified.
