PIPE FOR SMOKING TOBACCO Filed June 15. 1927 I VENTOR Patented Mar. 4, 1930 UNITED STATES FRANK M. ASHLEY, F BROOKLYN, NEW YORK PIPE non SMOKING TOBACCO Application filed June 15,

My invention relates to pipes for smoking tobacco.

The object of my invention is to provide a pipe for use with a filter which is located in the stem of the pipe and held in themoutha piece portion and is removable therewith from the stem and bowl portion.

A further object is to provide a pipe having a chamber formed between the stem and inner end of the mouthpiece to collect any juices which may flow from the bowl to said chamber which may not have been absorbed by said. absorbent material.

A further object is to provide a stem portion having a continuous duct therethru from end to end which may be easily cleaned by the insertion of the ordinary pipe cleaner.

Further objects and advantages of my invention will be hereinafter set forth: 7 Referring to the drawings which form a part of this specification- Fig. 1 is a longitudinal sectional view of a' pipe embodying my invention.

Fig. 2 is a longitudinal view of a portion of the stem of the pipe shown partly in section, together with the filter held thereby, both shown on an enlarged scale.

I A, indicates a bowl having a stem A preferable formed integral therewith substantially as shown and having a chamber A for tobacco. B, indicates a mouthpiece which is provided with a reduced portion B at its inner e'nd which fits in the bore C. A bore C of reduced diameter relative to the bore C communicates with the chamber A as illus trated.

The bore-C is preferably extended beyond the opening A in the bottom of the bowl to form a recess A into which the free end of the filtering material D may rest. The filtering material comprises a central wire portion E on which absorbent material D is mounted and held in firm relation to the wire E, which wire is flexible.

for smoke to the chamber C and thence thru the passage B in the mouthpiece B.

The filtering material is held in a hole 13 said material being compressed in forcing the .filter into said hole as illustrated.

comprising the passage B in cleaning the said passage.

The inner end of the bore C is formed with a conical recess C to freely guide the filter into the passage C when the mouthpiece is insertedin thestem ortion.

In smoking the pipe, the free end of the filter by'reason of resting in the recess A does not absorb much if any tobacco juice and may therefore be grasped by the fingers to remove the filter from the mouthpiece without soiling the fingers. 1

In smoking, the smoke passes thru the mesh or interstices of the filtering material and thru the chamber G to the inlet B and thru passage B the moisture in the smoke-being absorbed by the filtering material, and any excess flowin into and being retained by the chamber from which it maybe readily cleaned.- It will be found that the portion of the filter F adjacent the end of the mouthpiece will be practically free from moisture, as the smoke after itleaves the passage C flows to the'inlet B without depositing much if any moisture in this portion of the filter so that the filter may be grasped at this point to remove it fromthe stem without soiling the fingers.

In this construction the outer form of the pipe is completely preserved.

The ordinary pipe cleaner sold by most tobacco dealers thruout the United States The diameter of the bore 0 1s greater will serve as a filter. This cleaner is about seven inches in length and when out into four equal portions, each portion may serve as a filter when the pipe is made as illustrated in the drawings.

Having thus described my invention I extends beyond the passage leading from the claim as new: bowl to the passage in the stem.
