"NlTED STATES ENT FFIC SMOKEIWS PIPE.

Specification of Letters Patent. Patented Sept. 13, 1921i.

Application led July 22, 1919. Serial No. 312,589.

To all whom t may conce/m:

Be it known that I, CHRISTEA N. SUB- 'rinnmn a citizen of the United States, and a resident of New York city, in the county ot Bronx and State of New York, have invented certain new' and useful Improvements in Smokers Pipes, of which the following is a specification.

This invention relates to smokers pipes, and is herein disclosed as applied to a brierwood pipe having a straight stem.

It is often diicult to properly clean smokers pipes, especially at the stem between the bowl and the mouth-piece. According to the present invention the stem may include a removable portion which permits access to the interior. The removable portion is herein shown as an extension of the mouth-piece, which reaches through the stem substantially to the center of the bowl, and when withdrawn the extension may be opened to permit access to the bore through rwhich the smoke is inhaled.

To prevent the lire in the pipe from burning the extension it may comprise a metal end which underlies the bowl and is long enough to be cooled by the walls of the stem sufliciently to keep the metal from overheating the mouth-piece. The bowl may be somewhat larger than usual at its bottom, opening into an extension to which access from the top of the bowl is easy. This permits the very end of the bore to be cleaned from the bowl, while the rest of the bore may be cleaned by removing the mouthpiece.

Other features and advantages will hereinafter appear.

In the accompanying drawings Figure 1 is a side View of a pipe embodying the invention, largely in section.l

Fig. 2 is a plan View of the top half of the mouth-piece embodying my invention.

Fig. 3 is a similar view of the bottom half,

Figs. 4, 5 and 6 are sectional views along the line 4-4, 5 5, and 6-6 respectively ol Fig. 1.

The pipe comprises a stem 1 and bowl portion 2 which outwardly may be oi any desired or usual form. The stem is provided with" a bore 3 extending from the outer end 4 to the bottom of the bowl opening 5 which advantageously is enlarged at 6 ltoward and around its center so that any which (herein the upper) is grooved at 11 to receive the under cut edges of a dovetail tongue 12. Since-the tongue 12 and groove 11 are of a uniform size throughout, the members 9 and 10 are easily slid lengthwise out oi engagement with each other, thus exposing in each one-half of the bore 13. Since the bore 13 advantageously is divided evenly between the members 9 and 10 and is round, the halves thereof are thus completely exposed and can be cleaned thorouUhly and instantly.

lIVithin the stem, the mouth-piece is advantageously round and ts the bore 3 closely. The mouth-,piece may be made of any suitable material, and if made of a substance likely to be injured by the fire in the pipe, or likely to give a taste to the smoke if heated by the lire, may comprise extensions 14 and 15 made of metal or other heat resisting material. Each extension is advantageously formed as a circular arc and is suitably fastened to the reduced portions 16 and 17 of the mouth-piece body, so that each extension remains fast to its member 9 or 1() when the mouth-piece is separated for cleaning. Advantageously the extensions 14 and 15 abut against a collar 18 on each member 9 and 10 and formed integral therewith, the collar formed by the two halves lying just within the end 4 of the stem and there engaging against a cork gasket 19 lying in a recess at the end 4 of the bore 3.

The extensions 16 and 17 extend well within the bore 3 and the extensions 14 and 15 may be fastened thereto in any suitable manner. tensions 14 and 15 are of aluminum they may be conveniently glued to the extensions 16 and 17. The cork gasket 19 may also be glued inposition. This gasket serves to make a light joint for the mouth-piece. In some pipes I have found that the best size for the bore 3 is one centimeter.

rIhe extensions 14 and 15 advantageously fit closely the end of the bore, 3, where it I have found that if the ex- Y, merges into the bowl opening, the end of the lower extension 14 extending at least as far as the stem end of the bowl at 20, with the result that the withdrawal of the mouth-piece removes with the extension 15 all of the interior of the pipe which is not easily reached from within the bowl, and so cleans all of the pipe which a match stick (for example) will not reach from within the bowl. The extensions 16 and 17 terminate enough short of the bowl to permit the extensions 14 and 15 to be cooled by the body of the stem suiciently to prevent them from overheatin them.

l have found t at a dovetail may be slack enough to slide very easily and yet be tight enough to give what seems a perfect draft for the pipe.

While one form of the invention has been set forth with considerable stress on certain details to enable those skilled in the art to appreciate some of its advantages, what is claimed is:

1. In a smokers pipe the combination with a bowl having an opening of a stem having a bore reaching said opening, a mouth-piece comprising interlocking members slidable upon each other to expose the central bore of the mouth-piece, said members extending within the rst bore, and

fire resisting extensions of said members reaching said opening.

2. In a smokers pipe the combination with a bowl having a substantially central bottom opening, of a stern having a bore reaching said opening, metallic members forming a liningof the bore adjacent the opening, and a mouth-piece extending into the bore and comprising slidable interlocked members to which said metallic members are fast.

3. In a smokers pipe the combination with a bowl having a substantially central bottom opening, of a stem having a bore reaching said opening, re resisting members covering the bore adjacent the. opening, supports for said members forming a mouth-piece and slidable upon each other to expose the 4central bore of the mouth-piece, said supports comprising a shoulder to bear against the end of the stem, and a gasket at the end of the stem to close openings to preserve draft.
