UNITED STATES- FRANK M. ASHLEY, OF BROOKLYN, NEW YORK.

PIPE FOR USE WITH SMOKING TOBACCO.

Application filed December 12, 1925.

My invention relates to pipes for use with tobacco.

The object of my invention is to provide a pipe having means for filtering the smoke from the tobacco and absorbing the moisture which is drawn from the tobacco in smoking and which contains nicotine.

A further object of my invention is to so construct a pipe that the said filtering means may be instantly removed therefrom, either from the mouth-piece end of the pipe stem or from a point adjacent the bowl.

A further object is to provide a filter that is cheap and easily procured, and which may be thrown away after each pipe-ful of tobacco is smoked if desired, to insure a clean and dry smoke at all times.

Further objects of my invention will be set forth herein and the novel features of my invention will be more specifically set forth in the claims.

I have discovered that in order to properly filter the smoke and absorb the moisture contained in a pipe-ful of tobacco, that the a filter must have a considerable length through which the smoke must travel. I have also learned by experimenting, that the filter should have a stiffening material extending throughout its length in order that the filter may be easily inserted in the pipe, and used as a filtering and cleaning agent therefor. All of these conditions are met by my present invention.

Referring to the drawings which form a part of this specification:

Figure l is a longitudinal sectional view of a pipe having the stem and inner end of the mouth-piece bored to receive the filter, and showing the filter in operating position.

Figure 2 is a longitudinal sectional view of another form of pipe with the filter located therein.

Figure 3 is a longitudinal view of a pipe shown partly in section, showing the filter adjacent the bowl of the pipeexposed directly to view through the bowl, and this construction obviates the necessity of drilling the small holes in the bottom of the bowl as shown in Figure l and permits of easy cleaning.

Figure 4 is a longitudinal sectional view through the stem and inner end of the mouth-piece of a pipe, and is illustrative of my invention as applied to a pipe previously made, and also illustrates a simple and practical construction in which the filter may be Serial No. 74,928.

inserted or removed from the mouth-piece end or bowl end of the pipe without soiling the fingers.

Figure 5 is a longitudinal view of a filter shown partly in section.

'A, indicates the bowl of a pipe; B, the stem which is usually formed integral with the bowl, and C, the mouth-piece or bit. D, indicates the filter which is provided with a wire D which extends throughout its length.

This filter is like the keystone to an arch in this invention, in that it may be easily made'from an article already on sale and available at practically all cigar stores throughout the country, and therefore if -a person who has one of these filter pipes is unable to obtain the filters provided for use with the pipe, he can purchase the ordinary pipe cleaners at a cigar store and cut it in two equal lengths and use one length as a filter. The stem of the pipe is bored as illustrated at B the diameter of the bore being slightly larger than the diameter of the filter, which is about one-eighth of an inch, and I prefer to make the bore slightly larger under the bowlto provide a chamber E, which in Figure 1 is annular when the filter is in place, and in Figure 2 is represented by pocket or chamber, the object of which is to prevent the tobacco from jamming the filter and preventing the pipe from drawing freely.

I also provide a space or pocket F, between the inner reduced bore G and enlarged bore G of the mouth-piece to prevent the filter from closing the passage G, and also a space or pocket H in the stem adjacent the end of the mouth-piece, which pocket serves to catch any excess condensation which may occur whena single filter is used too long. A plug 1, is used to close the end of the bore or chamber E, said plug being provided ,With a thread P, as illustrated in Figures 1, and 3, or may be held by friction as illustrated in Figure 4. The plug I is also provided with a bore 1? of smaller diameter than that of the filter, and the end of the filter rests in said bore in snug engagement so that. ,-.byremoving the plug, the filter is also drawn out of the pipe therewith, and the end of the filter which rests adjacent to the inner end of the mouth-piece, and which is comparatively clean and dry, serves to clean the bore in the stem when drawn through the same and also may be grasped b the fingers to remove the filter from the plug without soiling the fingers with matter deposited in the filter.

In Figures 1, and 3, I have shown a straight stem pipe construction whereas in Figures 2, and 4, I have shown a curved mouth-piece fixed to a stem which is formed at an angle to the bowl of about 45, and inthis type of pipe I prefer to locate the plug I below the bowl as shown in Figure 2, or below the stem as shown in Figure 4, and I also have provided a plug for the pipe shown in Figure 2, having a flange I of large diameter and recessed at I, to provide a base to support the pipe in the same manner as the base J illustrated in Figures 1, and

illustrated.

3, supports the pipes of the straight stem type, as will be readily understood.

I make the filters in the same way as the pipe cleaners are made and of the same materials, but only about one half as long, which is about three inches. I may make the bore in the stem larger and longer for pipes having extra large bowls and correspondingly longer stems, and in this case the filters are made of larger diameter and greater length, but the diameter of the bore is not increased in proportion to the increased diameter of the filter, but in all cases is only a little greater than the normal diameter of the filter, which is only reduced at the plug where it enters the bore I as It will be noted that the end of the filter extends beyond the wall A of the pipe bowl where it extends into the bore I ofthe plug so that if the plug should be removed without holding the filter. tight enough to remove it, the end of the filter would project enough to be grasped by the fingers and removed from the pipe. This is also true of the end which extends into the mouth-piece as shown in Figures 2 and 4, by removing the mouth-piece the end of the filter is exposed and may be grasped to remove it from this end of the stem.

In making the type of pipes illustrated in Figure 1, I prefer to use a number of small holes K-K etc. as they are not so apt to be plugged with tobacco and the pipe draws more freely than when but one small hole is use When the pipe is smoked the absorbent material collects the moist ondensations and matter extracted from the tobacco, and only the smoke remaining passes through the small bore G and a clean smoke is provided.

Having thus described my invention I claim as new:

1. The combination of a pipe having a bowl and a stem integral therewith, the bottom of the bowl having a cleaning chamber and a detachable plug therein providing a base or support for the bowl, a smoke filter of absorbent material extending the entire length of the stem and removable from either end thereof, one end of said filter being of reduced thickness and attached to the plug and of alength to extend through said cleaning chamber whereby it may be seized by the fingers when disconnected from the lug.

2. A pipe having a bowl and a mouthpiece, a stem having a direct continuous bore leading from end to end thereof, a removable plug held in one end of said bore and having a hole extending beyond the adjacent end of said bore, a removable filter of absorbent material of smaller diameter than that of the bore and having a central wire extending its entire length, and resting in the hole in the plug beyond the adjacent end .of said bore in the stem, and extending therefrom to the opposite end of said stem adjacent the inner end of said mouth-piece.

3. A pipe having a bowl and a mouthpiece, a stem having a direct continuous bore leading from end to end thereof, a removable plug held in one end. ofsaid bore and having a hole. extending beyond the adjacent end of said bore, a removable filter of absorbent material of smaller diameter than that of the bore and having a central wire extending its entire length, and resting in the hole in the plug beyond the adjacent end of said bore in the stem, and extending therefrom to the opposite end of said stem adjacent the inner end of said mouth-piece, said here being enlarged in diameter adjacent the bowl to form a trapping chamber.

4. A pipe comprising a bowl, a stem and a mouth-piece, and a removable filter of absorbent material having a wire extending its entire length resting in the stem and extending beyond the stem at both ends thereof to permit the removal of the filter from either end thereof, said filter being of less diameter than said bore.

5. A pipe having a bowl, a mouth-piece and a stem, said stem having a single bore extending therethru, a removable filter comprising a central wire carrying an absorbent filtering material thereon and extend-ingbeyond the bore at each end thereof, a removable plug having a hole into which one end of the filter rests, the construction being such that by removing the plug the filter may be grasped b the fingers in case the filter should stick 1n the bore.
