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

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.
