SMOKING PIPE ATTACHMENT‘ ‘ Carl Bergman, Hopatcong, N. J. Application March 22, 1937, Serial No. 132,286 3 Claims. This invention relates to new and useful im provements in a smoking pipe attachment. This invention has for an object the construc tion of an attachment as mentioned which is 5 characterized by a perforated compound cap for engagement on the bowl of a pipe. Still further the invention proposes the asso ciation of a flat perforated inner head mounted on a resiliently mounted stem extended from the 10 perforated compound cap by which the burned tobacco may be pressed down. Still further the invention proposes the con struction of an attachment as mentioned which is characterized by perforated inter-engaging 15 cap sections, one set within the other, and ?ex ible tubes connecting the perforations of said sections in a manner to control the passage of air and ?uids therethrough. This attachment is in tended to be used in heavy rains and storms. 20 For further comprehension of the invention, and of the objects and advantages thereof, ref erence will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the 25 invention are more particularly set forth. In the accompanying drawing forming a mate rial part of this disclosure:— Fig. 1 is a perspective view of a smoking pipe attachment constructed according to this inven 30 tion. Fig. 2 is a sectional view taken on the line 2--2 of Fig. 1. Fig. 3 is an elevational view looking in the di rection of the arrows 3-3 of Fig. 2. Fig. 4 is a similar view to Fig. 2 but illustrating a modi?ed 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 4.0 compound cap consists of an outer cap section 10° and an inner cap section IUd. Each of these sections have perforated end wall portions and depending skirt portions. It is the skirt por tions that engage one upon the other. The inner 45 cap Ind 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 He and a plurality of branch portions l'lb. It is possible to slightly turn the 50 outer cap Hi0 to engage the pin IS in any of the branches l1 and so hold the cap sections in va rious relative positions. The top wall of the cap section It’!0 is formed with perforations I2’. The top wall of the cap 55 section It)[1 is formed with perforations [2". (Cl. 131--176) These perforations are staggered and are con nected with each other by ?exible tubes I9. When the sections IF]0 and Ill‘1 are adjusted to relative positions the tubes l9 will be moved. Normally, in the collapsed condition of the cap 5 sections the tubes I9 are loose and automatically assume the shape of an S-?gure on its side. This shape acts as a trap to retain small quantities of water which may accidentally drip through cer train 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 “C 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 15 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 ?at 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 Mid 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 25 portion on Me by which it may be gripped and manually moved outwards. In Fig. 4 the outer cap I00 is spaced from the inner cap llib by a seat lllh formed in the outer cap. Cotton, sponge, felt or other absorbent ma 30 terial 20 is placed in the hollow space 2| formed by the two caps. This absorbent material 20 may be saturated with ?avoring substance to change the taste and fragrance of the smoke. The per forations I2’ in the upper cap Ill6 and perfora tions 12” in the lower cap Hlb are in staggered relation to permit a good mixture of the air drawn in by the smoker, with the ?avoring sub stance 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 modi?cations coming within the scope of the invention as de ?ned 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 per~ 50 forated inter-engaging cap sections, one an in ner section and the other an outer section, flex~ ible tubes connecting the perforations of said sections, means for holding said sections rela tively axially adjusted to slacken the ?exible 2 2,136,537 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 per Cit forated inter-engaging cap sections,» one an inner section and the other an outer section, means for 3. A smoking pipe attachment comprising an inner perforated section having a depending skirt portion which is adapted to frictionally en~ gage over the top of a pipe bowl, an outer per forated section having a depending skirt portion which is adapted to engage over the top of said spacing said sections, perforations in both cap sections, said cap sections having concentric ?anges or skirt portions, the inner of said ?anges inner perforated section, ?exible tubes connect ing the perforations in said sections, and a shoul~ being adapted to be frictionally mounted on a tion of said outer section which is adapted to en 10 gage the top face of said inner section to limit the pipe bowl, absorbent material in the cavity be tween the spaced inter-engaging cap sections and ?avoring substance within the said absorb ent material, the perforations in the spaced in ter-engaging cap sections being in staggered re lation to permit the air drawn into the pipe by the smoker to mix with the ?avoring substance in the absorbent material. der arranged on the inner face of the skirt por 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 15 said perforation in said outer section during a rainstorm.
