Nov. 15, 1938, c. BERGMAN 7 7 SMOKING PIPE ATTACHMENT Filed March 22, 1937 lNV ENTQR CARL- Banana:

ATTORNEY Patented Nov. 15, 1938 UNITED STATES PATENT OFFIQE 3 Claims.

This invention relates to new and useful improvements in a smoking pipe attachment.

This invention has for an object the construction of an attachment as mentioned which is characterized by a perforated compound cap for engagement on the bowl of a pipe.

Still further the invention proposes the association of a flat perforated inner head mounted on a resiliently mounted stem extended from the perforated compound cap by which the burned tobacco may be pressed down.

Still further the invention proposes the construction of an attachment as mentioned which is characterized by perforated inter-engaging cap sections, one set within the other, and flexible tubes connecting the perforations of said sections in a manner to control the passage of air and fluids therethrough. This attachment is intended to be used in heavy rains and storms.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a perspective view of a smoking pipe attachment constructed according to this invention.

Fig. 2 is a sectional view taken on the line 2--2 of Fig. 1.

Fig. 3 is an elevational view looking in the direction of the arrows 3-3 of Fig. 2.

Fig. 4 is a similar view to Fig. 2 but illustrating a modified form of the invention.

The smoking pipe attachment, according to this invention, comprises a compound cap NJ for engagement upon the bowl of a pipe I I. This compound cap consists of an outer cap section 10 and an inner cap section IU Each of these sections have perforated end wall portions and depending skirt portions. It is the skirt portions that engage one upon the other. The inner cap In has a projecting pin l6 which engages into a bayonet slot I1 formed in the skirt of the outer cap section. This bayonet slot I! has a straight portion H and a plurality of branch portions l'l It is possible to slightly turn the outer cap Hi to engage the pin IS in any of the branches l1 and so hold the cap sections in various relative positions.

The top wall of the cap section It! is formed with perforations I2. The top wall of the cap section It) is formed with perforations [2".

These perforations are staggered and are connected with each other by flexible tubes I9. When the sections IF] and Ill are adjusted to relative positions the tubes l9 will be moved. Normally, in the collapsed condition of the cap sections the tubes I9 are loose and automatically assume the shape of an S-figure on its side. This shape acts as a trap to retain small quantities of water which may accidentally drip through cert ain of the top openings i2 during a rainstorm. If in calm weather it is desired that more air be supplied to the pipe the outer section may be extended so that the tubes 19 are straight, as indicated by the dot and dash lines l9, and then the restriction to the passage of air through the tubes is reduced.

The smoking pipe attachment also includes a stem Ml which is slidably mounted through the center of the compound cap 10'. This stem has a fiat inner head It formed with perforations iii. A spring l'l is coaxially mounted upon the stem l4 and acts between the inner face of the inner cap section Mi and the head I5 for urging the head against the tobacco I8 within the pipe bowl. The outer end of the stem M has a small head portion on M by which it may be gripped and manually moved outwards.

In Fig. 4 the outer cap I0 is spaced from the inner cap lli by a seat lll formed in the outer cap. Cotton, sponge, felt or other absorbent material 20 is placed in the hollow space 2| formed by the two caps. This absorbent material 20 may be saturated with flavoring substance to change the taste and fragrance of the smoke. The perforations I2 in the upper cap Ill and perforations 12 in the lower cap Hl are in staggered relation to permit a good mixture of the air drawn in by the smoker, with the flavoring substance in the absorbent material 20.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:-

1. A smoking pipe attachment comprising perforated inter-engaging cap sections, one an inner section and the other an outer section, flexible tubes connecting the perforations of said sections, means for holding said sections relatively axially adjusted to slacken the flexible Cit tubes or to extend them, and said cap sections having skirt portions by which the attachment may be frictionally mounted on a pipe bowl.

2. A smoking pipe attachment comprising perforated inter-engaging cap sections, one an inner section and the other an outer section, means for spacing said sections, perforations in both cap sections, said cap sections having concentric flanges or skirt portions, the inner of said flanges being adapted to be frictionally mounted on a pipe bowl, absorbent material in the cavity between the spaced inter-engaging cap sections and flavoring substance within the said absorbent material, the perforations in the spaced inter-engaging cap sections being in staggered relation to permit the air drawn into the pipe by the smoker to mix with the flavoring substance in the absorbent material.

3. A smoking pipe attachment comprising an inner perforated section having a depending skirt portion which is adapted to frictionally engage over the top of a pipe bowl, an outer perforated section having a depending skirt portion which is adapted to engage over the top of said inner perforated section, flexible tubes connecting the perforations in said sections, and a shoulder arranged on the inner face of the skirt portion of said outer section which is adapted to engage the top face of said inner section to limit the engagement of said outer section on said inner section to a position in which said flexible tubes assume an S-shape which is adapted to act as a trap for drops of water which may pass through said perforation in said outer section during a rainstorm.
