It has been found that in devices of this char
acter, by reason of the heat generated in the
chamber in which the tobacco is consumed, the
device becomes heated to such an extent that it
is uncomfortable to handle the same. It is there
fore another object of the present invention to
provide improved means for insulating the smok
15 ing or tobacco chamber, ther-eby reducing to a
desired size and configuration. One end of the
body member is provided with a portion I5 of
a bayonet joint element which is adapted to re-ceive the end I1 of a stem I8. The end Il of this
stem is shaped to form the other element of a
bayonet joint, so as to separably lock the body
and stem members together. The extremity I9
of the body member contacts a circumferential 5

Arranged in the space between the periphery of
the member 2| and the inner face of the body
member I5 is insulating material 28 of any suit
able material. This insulating material is prefer
ably in the form of a tubular member, as shown in
Figure 11, and is provided with a ycircumferential
flange or collar 29, which latter, when the in 45
sulating material is in position, will project into
the space between the shoulder 25 of the member
2| and the extremity 2l of the body member I5.
If desired, lugs or projections 30 may extend
from the extremity 2'! of the body member I5 to 50
impale the flange 29 of the insulating material
28, and contact the shoulder 26 of the member
2|, to hold the latter against rotation with re
spect to the body member when the parts are
being fastened together.

The body portion of the member 2| is substan
tially co-extensive with the body m-ember l5 and
in this body member l5 adjacent the point of
connection of the body member l5 with the stem
i8, is provided a circumferential shoulder 3|.
The body portion of the member 2| is of ductile
material so that when the parts l5, 2| and 28
are assembled, the extremity of the body portion
2|, which is in proximity to the shoulder 3|, is
flanged or deflected over the shoulder 3|,- and
with it the adjacent extremity of the insulating
material 28 will be ñanged over the shoulder 3|
as at 32.
Within the stem I8 is a chamber or recess 33
15 which terminates short of the free end of the
23 of the member 2| as well as the openings 6|
in the member 49.
The abutment member is placed in position so
that its outer face is disposed in close proximity
to the inner face of the partition 22 and is pro
vided with a circumferential groove 56 through
the bottom of which groove the spaced slots or
openings 55 open.
Projections 51 are provided on the inner face
of the partition 22 which enter and move within
the groove 56 so as to prevent accumulation of
ashes or foreign matter in the groove which would
impair the circulation of smoke or air through
the openings 55. Similar projections 58 are pro
vided on the other side of the partition 22 and
stem but opens through the other end. rThe nu- l these projections 58 enter and move in a groove
meral 34 designates a bushing or bearing mem
ber having a circumferential ñange or head 35
of a diameter greater than the diameter _of the
20 bearing member 34. This flange or head 35 en
gages and rests upon a raised portion at the end
of the stern and which raised portion is of a diam
eter considerably less than the diameter of the
adjacent portion of the body member l5, so as
25 to form a space beneath the flange or head 35
for receiving a filter 31 which encompasses the
raised portion., This filter 31 may be of any suit
ablematerial and is of a diameter substantially
. co-extensive with the diameter of the flangeor
30 head 35.
It will be manifest that the bushing or bearing
34 being screwed into the end of the stem will be
held in position and pressure will be relieved from
"as
the ñlter 31, yet the latter will be maintained in
position. This filter 31 extends over one or more
passages 38 in the stem that open through the
stem beneath the filter and also open through the
outer extremity of the stem. Within the cham
ber or recess 33 is arranged a plunger 39 which
40 substantially fills the chamber, and connected
thereto is a rod 4U _of a diameter considerably
less than the diameter of the chamber. This rod
48 projects through the bushing or bearing mem
ber 34 and is connected to a follower 4| which
45 is of a size to ñt within the tobacco chamber
59 in the lower face of a portion of the cap mem
ber 49.
This cap member is provided with an open
end 6l] and through the bottom of this open por 20
tion are arranged openings 6|. The projections
58 are of such a diameter that when they stand
in alinement with the openings 6|, there will be
a free air or smoke circulating space around the
projections 58 and through the openings 6|.
The cap member 49 is also provided with a
recess 62 which opens through the face that is
invproximity to the end of the body member I5
and the wall'of this recess is provided with a cir
cumferential groove 63.
30
'
The end member 2| above the shoulder 26 is
provided with vertical slots 64 which extend
through the shoulder 26 and have communica~
tion with the groove 25.
Two of these slots are
preferably provided, one opposite the other, and
portions of the'walls of the slots intermediate
their extremities are enlarged or cut away as at
65.
'
'
`
A locking spring 66 is provided which'is pref
erably of the semi-circular form, the extremities 40
thereof being deflected as at 61 to form spaced
parallel portions, and mounted upon these spaced
lparallel portions 61 are balls or spheres 68.'
The body portion of the member 66 is adapted
to be> seated in the groove 25 in the end mem
which is formed by the member 2|.
The peripheral edge 42 of the follower may be
Àber 2|, as shown more clearly in‘Figure'10,`while
reduced to form a cutting edge and any suitable
number of slots or openings 43 may be provided
50 through the follower@ At the diametric center
of the follower there may be provided a raised or
convexed portion 44, for a purpose to be set forth`
'seated in theslots 64.' The balls or spheres 68
are freely movable upon the portions 61 of the
This follower 4| is normally urged forwardly
in the tobacco chamber preferably by means of
55 a spring 45 disposed beneath the plunger 39 and
the end wall of the chamber 33.
Arranged within the tobacco chamber formed
by the member 2| and at the outer end thereof is
an abutment member 46 provided with a stem
60 41 that is rotatably mounted in a bearing 48 in
a cap or end member 49. This stem 41_is pro
vided with a portion 50 which is angular in cross
section and also with a circumferential groove
65
70
or recess 5| adjacent the angular portion 50.
A spring split washer 52 is provided, which en
compasses the stem 41 and enters the recess 5|.
The washer 52 is of a width to extend across an
opening 53 in the partition 22` of the liner and
Aend member and through which opening 53 the
the spaced vertical or parallel portions 61 are
member 66 and enter the- enlarged or cut away 50
portion 65 of the slots‘64. _ '

'
When thisy member 66 is in position, the balls
or spheres 68 will bepartially'seate'd. in the end
memberZl and partially seated in the cut away
portion 65 of the slots 64 in the end member 2|, 55
and will also be partially seated in the groove 63
in the c'ap member 49 to lock these parts to

Vdesired to remove the cap 49 from the end mem
ber, which may be done by applying force to the
cap’ member while the end member is held, and
by exerting said force in a direction lengthwise
of the axis of the cap member, the balls 68 by
reason of the resiliency of the portions 61 of the
spring member 66, will be forced into the cut away
portion 69 of the slot 64, so that the balls will` be
65
moved out of the groove 63, thereby allowing the 70
stem 41 passes to substantially. fill the opening.
The abutment member is provided at its cen~
parts to be separated. Upon removal of the cap
member the balls 68 will assume their normal
',tral portion with a convexed surface 54 projecting
into the tobacco chamber and is also provided
positions, but when the cap member is replaced
with openings 55 which register with the openings
45
the balls 68 will be temporarily depressed back
into the cut away portion 69, until the cap is
2,119,198
seated, after which the balls will spring out and
enter` the groove 63.

in the chamber to urge the tobacco against said
of the device in one hand and rotating the cap
abutment, the said abutment being shaped to
member 49 with respect to the body member.
The cap member may be provided with a fluted
20 or serrated periphery ‘l2 provided for that pur
pose.
By reason of the shape of the abutment mem
ber 46 and the follower 4l, and particularly the
convexed portions 44 and 54, the tobacco will be
25 forced outwardly against the walls of the tobacco
chamber, thereby resulting in a better consump
>tion of the tobacco. The ashes are removed by
rotating the cap member. As the abutment
rotates, the ashes at the lighted end of the to
30 bacco will pass through the openings 55 in the
abutment member 46 as well as the openings 23
in the partition 22, and thence through the open
ings 6I in the cap member 49.
By reason of the insulation 28 the body‘mem
ber I5 will be kept comparatively cool and the
temperature thereof will not rise to a point where
the device will be uncomfortable to handle.
In the use of the device the smoke is drawn
from the tobacco chamber through the openings
40 43 in the follower 4l into the space between the
stem and body members and below the follower
4I. From there it will be drawn through the>
filter 31 and thence through the openings 38 in
the stem member.

‘
The projections 58 and 51 are of diameters
less than the diameters of the openings adja
cent which they stand so that no matter what
position the projections may assume with rela
tion to the respective openings, the circulation
50 of air through the openings will not be inter
rupted or cut off.
While the preferred form of the invention has
been herein shown and described, it is to be un
derstood that various changes may be made in
55 the details of construction, and in the combina
tion and arrangement of the several parts, with
in the scope of the claims, without departing
from the spirit of this invention.
