WALTER S. BLAKE, OF ST. LOUIS, MISSOURI.

TOBACCC-Pl PE BOWL.

SPECIFICATION forming part of Letters Patent No. 387,135, dated July 31, 1888.

(No model.)

To all whom it may concern..-

Be it known that I, WALTER S. BLAKE, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Tobacco-Pipe Bowls, of which the following is a full, clear, and exact descripti on, reference being had to the accompanying drawing, forming part of this specification.

The drawing is a view, part in side elevation and part in vertical section.

My invention relates to an improvement in tobacco pipe bowls; and it consists, broadly,in a bowl made of comminuted or disintegrated corn-cobs mixed with a suitable cementitious matter and pressed into shape, as more fully described hereinafter.

The invention consists, further, in a pipebowl having an outside coating composed of certain ingredients, as will be hereinafter described.

Referring to the drawing,1 representsa pipebowl, partly in vertical section, made as here- 7 inafter explained.

In carrying out the process, I take a sufficient quantity of the comminuted or disintegrated corncobs, and, by preference, dampen it and add a portion of cementitious mattersuch as silicate of potasl1say,two and one-half parts to twenty parts of the corn-cobs, and form a paste, which is thoroughly mixed and pressed in suitable molds. The molded pipebowl is then allowed to dry and harden. After this it may be lined on the inside with a mixture of two parts of silicate of potash and one part of calcined magnesia, if desired, and the outside may be coated with a mixture of kaolin and white glue, with a consistency of thick paint, put on with a brush, allowed to harden, and afterward fined down smooth with sand-paper, and the surface may then be treated with a gelatine or india-rubber figured stamp,using ordinary printing-ink or any suitable coloring material to form any suitable figure designed-such as an imitation of the grain ofa corn-cob, 856. After this is dry, it gloss or finish of silicate of potash is added, applied with a brush. The stem-hole is then bored, and eyelets or bushings are inserted in the hole, if required, to receive the stem.

In my application, Serial No. 260,115, filed December 24, 1887, I have described, but not claimed, a pipe-bowl made of comminuted corn-cob pressed into shape, which, so far as these features are concerned, is similar to this invention.

I am fully aware that silicate of potash and calcined magnesia have before been used as a fire-proof medium, and I do not profess to be the discoverer of this fact; but I have discovered in these ingredients a new Virtue-z. 6-, that they have no unpleasant taste or smell when burned with tobacco.

What I claim, and desire to secure by Letters Patent of the United States, is-

1. As a new and improved article of manufacture, a pipe-bowl composed of comminuted corn-cob and cementitious matter, as set forth.

2. A corn-cob-pipe bowl having an outside coating of a mixture of kaolin and glue, substantially as described.

3. A pipe-bowl having an inside lining of a mixture of silicate of potash and calcined magnesia and an outside coating of a mixture of kaolin and white glue, substantially as described.

4. A pipebowl composed of disintegrated corn-cob pressed into shape, having an inside lining of a mixture of silicate of potash and calcined magnesia and an outside coating of kaolin and glue decorated, and the decorated surface varnished with silicate of pot-ash, substantially as described.

YVALTER S. BLAKE.
