POROUS COVER FOR TOBACCO-JARS.
SPECIFICATION forming part of Letters Patent No. 280,477, dated July 3, 1883.
Application tiled February 2S, 1883. (No model.)
T0 @ZZ whom, t may concern.-
Be it known that I, OHAs. B. HULL, of Dctroit, in the county of Wayne and State ofMichigan, have invented new and useful Improvements in Porous Covers for Tobacco-Jars, and I do hereby declare that the following is a full, clear, and eXact description thereof, reference being had to the accompanying drawings, which form a part of this specification.
This invention relates to certain new and useful improvements in the construction of covers for jars or pails from which fine-cut tobacco is retailed. Tobacco coniined in such packages is apt to become dry from the air entering, as the top is frequently removed for the purpose of supplying` customers.
The object of this invention is to provide a cover of porous earthenware, uponwhich a sponge saturated in water is to be placed, thereby furnishing a means for keeping the top of the tobacco in a jar, which is from time to time exposed to the air, moist.
Figure l is a perspective view of my invention as applied to a tobacco-jar. Fig. 2 is a vertical central section of thesame.
In the accompanying drawings, which form a part of this specification, A represents a saucer-shaped dish, its upper edge terminating in a horizontal flange, c, to rest upon the top wall of the jar, while the saucer-shaped portion of the cover projects within said j ar. From the center of this saucer-shaped top rises a stem or handle, B, with an enlarged the cover is manipulated. Vhen in use a sponge is fitted around the stem within the saucer and saturated with water, and the cover, being made of porous ware, allows such water to percolate through the cover, thereby moistening the air in the jar and the tobacco brought in contact with such air. It is essential that a sponge be employed for the purpose described, for if water is poured into the saucertop it would slowly percolate through the top in such quantity as to wet the tobacco in the jar, which is objectionable.
Vhat I claim as my invention is- 1. A bowl-shaped cover for a tobacco-jar, made oi' porous earthenware, having its upper edge constructed to rest on the edge of the j ar, and adapted to hold a sponge saturated with water below the top of the jar, substantially as specified.
2. A bowl-shaped cover for a tobacco-jar, made of porous earthenware, having its upper edge constructed to rest on the edge of the jar, provided with a stem-handle rising from the center of the bottom, and adapted to hold a sponge saturated with water below the top of the jar, substantially as specified.
