ATTACHMENT FOR SMOKING DEVICES
John G. Tarr‘ant, New York, N. Y.
Application March 2'7, 1934, Serial No. 717,580
13 Claims.
This invention relates to improvements in
smoking devices, such as pipes and cigar and
cigarette holders, and more particularly to means
for treating and directing the flow of smoke dur
,,ing its passage from the point of origin to the
mouth of the smoker.
It is an object of this invention to cool and
clean the smoke by providing a device having a
combined cleaning and baffling element, thereby
10 ;increasing the length of the path of flow of
smoke from tobacco to mouth.
Another object is to provide a device of the
character described having a combined position
ing and closure means to adjust the position of
15 the cleaning and baffling element and to close
one end thereof.
Another object is to provide a device of the
character described in which the said cleaning
and baf?ing element is readily replaceable.
Other and further objects of this invention
20
will be apparent from the drawing and the fol
lowing description and claims.
In the drawing, Figure 1 is a longitudinal view
of one modi?cation of my device embodied in a
cigarette holder and shows a cigarette in posi
tion in the end of the holder.
Figure 2 is a longitudinal sectional view of the
cigarette holder shown in Figure 1.
Figure 3 is a longitudinal view of the inner
tubular element 8 of Figure 2.
Figure 4 is a longitudinal view of a combined

of the element 8 of Figure 3 suitable for position
ing therein. The assembly of the remaining ele
‘ments to complete the pipe stem is also, indicated.
(Cl. 131-12)
Similar numerals refer to similar parts
throughout the several views.
Referring to the drawing in greater detail, a
device constructed according to the present in
vention may comprise a bit or mouthpiece I hav
ing a smoke passage ll therethrough. An outer
tubular member 2 is mounted, preferably sep
arately, as by a threaded joint, on one end of the
mouthpiece. The opposite end of the tubular
member 2 is mounted, also preferably‘ by an easily 10
separable connection, on a tobacco holding mem
ber, such as cigar or cigarette holder 3 or pipe
bowl 3’. An inner tubular member 8 is mounted
in the rear end of the member 3, the smoke pas
sage 9 through the member 8 forming a con 15
tinuation of the smoke passage ‘I through the
member 3. Spacing means Iii, which may suit
ably be in the form of notched radial ?ns, are
mounted on the member 8, preferably at or near
the end connecting with member 3. An inter
mediate tubular member ii is positioned around
the member 8 and is spaced therefrom and pref
erably also from the end of the member 3 by
the spacing means It. The inner surface of this
member ii makes an easily separable connec
25
tion, preferably a loose frictional contact, with
the spacing means it so that on disassembling
the device this member is removed with the
inner tubular member 3 and may then be easily
detached therefrom, preferably by giving mem
ber 3 a slight jar or shake to avoid having to
touch the member M. This member ll becomes
soiled in, use, and may be readily removed and
replaced with a fresh member whenever desired.
This member is preferably a cylinder having a ,
diameter greater than half the inside diameter of
the outer tubular member 2, in order to permit
its ready alignment and closure by the means
illustrated. These comprise a tubular member 5
having a closed outwardly projecting conical end
of a maximum diameter greater than the inside
diameter of the member ii and preferably less
than that of the outer member 2.
The end of the
member l I is closed by being pushed against this
conical surface when the device is assembled.
The member 5 is preferably mounted in the end
of the mouthpiece l in such manner that it is a
continuation of the smoke passage 4. Suitable
means for‘ the passage of smoke from the space
between the member l l and the outer member 2
into the smoke passage ll of the mouthpiece i may
comprise preferably one or more holes 6 in the
member 5 between the points of contact with the
member H and the mouthpiece I, although the 55
2
2,126,422
smoke passage 4 may connect directly with this
space, if desired.
While the device has been illustrated with the
inner tubular member 8 connected with the to
bacco holding member 3 and the member 5 con
nected with the mouthpiece I, it is recognized
that these positions may be reversed, member 8
being mounted in mouthpiece l and member 5 in
member 3, without departing from my inven
10 tion.
The flow of smoke will then be reversed
in its passage through the device, as will be un
derstood. The manner of assembly illustrated is
preferred, however, as it will be found to be
cleaned more readily.
The manner of adapting the device for use
15
with a pipe, as illustrated in Figure 10, in which
the spacing means I0 is continued as a screw IU’
of su?icient length to engage both the outer
member 2 and the stem of the pipe bowl 3', may
20 also be varied, and any other suitable connec
tion may be used as desired. For example, the
projecting end of the member 8' may be in the
form of a slightly tapered cylinder, making a
tight frictional connection with a similarly
25 shaped recess in the stem of the pipe bowl 3'.
The intermediate tubular member H may also
be closed at one end, as illustrated by | I’ in Fig
ure 10. In this case the alignment and closure
member 5 may be omitted, or it may be used
30 simply as a spacing means 5a for positioning the
closed end of the member ll. Figure 10 shows
a section through one of three spacing means 5a
which may be made as a part of the mouth
piece. The smoke passage ll will connect directly
35 or through suitable openings in the spacing
member 5a, with the space between member II
and outer member 2.
The member ll serves to clean and cool the
smoke by increasing its path of ?ow through the
40 device and by the reversals of flow caused there
by which tend to throw out dust, droplets of
moisture and other non-gaseous matter sus
pended in the ?owing gas. This purifying ac
tion may be increased by constructing the mem
45 ber ll of a suitable absorptive material, which’
may even be somewhat pervious to gas. For ex
ample, it may be made so that at least one sur
face, inner or outer or preferably both, is made
of absorptive paper, decolorizing carbon, or other
50 materials having similar functions. The ?owing
gas may also be ?ltered by placing a suitable ?l
tering medium, such as loose cotton, in the an
nular spaces inside or outside this member, or
both. It has been found, however, that such ?l
ters, even when loosely matted, are di?icult and
inconvenient to insert and cause objectionably
high pressure drop in use. A preferred ?lter may
be prepared by attaching the ends of relatively
short ?bres to the surface of the member II.
60 The ?bres then extend into the ?owing stream
and 50 respectively.
The ?bres may consist of
cotton, wool, silk, hemp, wood pulp, rayon and
other natural and synthetic ?brous materials.
They may be attached to the surface of the mem
ber II by any glue or cement suitable for the
intended use or by other means, or they may be
made a part of the surface by being mounted
therein during its formation.
A suitable method
particularly for obtaining ?bres attached to
the inside surface is to apply the ?bres to a sheet 10
of material, suitably paper, which is then rolled
and formed into cylinders of desired diameter
and length. The ?bres may be caused to stand
out from the surface to which they have been
attached, in the desired manner, by imparting 15
an electrical, preferably an electrostatic, charge
to them while the adhesive is drying or setting.
They may also be used in the form of a fabric,
such as a chenille or a transparent velvet, which
has numerous ?bres with loose ends projecting 20
from the surface of the fabric. Such fabrics may
be strengthened and the back of the fabric made
more rigid by application to one or both sides
of a sheet of paper, Cellophane, or other suitable
material. Or sugar water or a solution of a suit
able hard resin in a volatile solvent may be ap
25
plied the back of the fabric and allowed to set
preferably after the cylindrical form has been
prepared.
While the invention has been illustrated and
described herein in its preferred forms, it is to
be understood that it may be used in other forms,
embodiments and modi?cations without depart
ing from the spirit thereof. This invention is
not to be limited to any examples, applications
or explanations, all of which have been presented
herein solely for purposes of illustration, but is
limited only by the following claims, in which it
is desired to claim all novelty insofar as the prior
art permits.
