Description

i) 1951 v w. RECORD 2,551,290
SMOKING PIPE Filed June 27, 1947 Patented May 1, 1951 UNITED STATES PATENT OFFICE 3 Claims.
My invention relates to improvements in smoking pipes.
A primary object of the invention is to provide a pipe of novel construction, wherein the smoke and condensate are caused to pass through an extended channel and into a trap chamber, before entering the stem of the pipe, whereby such smoke is freed, to a great extent, of moisture and nicotine, and a pleasant clean smoke is provided.
A further object of the invention is to provide a smoking pipe of the above mentioned type which may be conveniently cleaned, even while there is burning tobacco in the pipe bowl.
A further object is to provide a pipe of simplified design, and therefore practical and economical to manufacture, said pipe being durable and attractive in appearance.
Other objects and advantages of the invention will be apparent during the course of the following description.
In the accompanying drawings, forming a .part of this application, and in which like numerals are employed to designate like parts throughout the same,
Figure 1 is a perspective view of the smoking pipe embodying my invention,
Figure 2 is a perspective view of the pipe bowl removed,
Figure 3 is a perspective view of a coupling member and. stem, partly broken away,
Figure 4 is a central vertical longitudinal section through the pipe, with parts broken away,
Figure 5 is a horizontal section taken on line 5--5 of Figure 4,
Figure 6 is a front end elevation of the pipe with the .pipe bowl removed, and, V
Figure '7 is a fragmentary section taken on line 'I! of Figure 6.
In the drawings, where for the purpose of illustration, is shown a preferred embodiment of the invention, the numeral I designates a pipe bowl of rounded shape having a convex external surface, and provided with the usual tobacco burning chamber II. The rear side of the bowl I0 has formed in it a. vertical dove-tail groove or recess I2, forming a vertical flat surface I2, and extending to the bottom of the bowl. The dovetail groove I2 is open at its bottom end and has sides I3 which converge upwardly, and the groove I2 terminates short of the top of the bowl forming a stop shoulder I4, having a downwardly inclined wedge surface I5. The bottom of the pipe bowl I0 is provided with a horizontal recess I6,
disposed near the rear side of the bowl and leading into the vertical dove-tail groove I2. The sides I! of the horizontal recess :6 preferably converge upwardly. It can be seen that the groove I2 and recess l6 constitute a right angle or L-shaped recess in the rear side and bottom of the pipe bowl, Figure 2, and the L-shaped surface formed by this recess is preferably rounded at its corner, as shown at IT. The forward end I6 of the recess I6 is preferably vertical. Formed in the rear vertical surface I2, near the lower end of such surface and adjacent to the right side I3, Figure 2, is an opening or smoke port I8, leading into the tobacco burning chamber II near the bottom of the same, Figure 4. Also formed in the surface l2 near the lower end of the same, and spaced opposite from the port I8, and adjacent to the left side I3, Figure 2, is'a preferably substantially hemispherical recess I9, for a purpose to be described.
The numeral 20 designates a coupling member including an elongated stem portion 2 I, and a substantially vertical combined filter member and head or wedge 22 formed integral with the stem portion and at substantially right angles thereto. The forward end of the Vertical member 22 provides a fiat surface 23, and the sides 24 of the member 22 converge upwardly. These sides also converge rearwardly, Figure 5, and are adapted to coact with sides I3 of the dove-tail groove I2. The lower end of the vertical member 22 carries a horizontal right angle extension or tongue 25, having a forward vertical end 26 and upwardly converging-sides 21, conforming to the sides IT. The top of the member 22 is beveled to provide a downwardly inclined surface 28 for coaction with the surface l5. A fillet 29 is provided where the tongue 25 joins the fiat surface 23, and this fillet fits the rounded corner I1 in assembly. Formed in the flat surface 23 of the member 22 is an inverted U-shaped groove 30, preferably semi-circular in transverse cross section. The two legs 3! of this groove 30 are preferably parallel to the sides 24, and their lower ends terminate near and above the tongue 25. The top 32 of the inverted U-shaped groove is disposed near the top 28. The lower end of the right leg 3|, in Figure 3, leads into a preferably substantially hemispherical recess 33, formed in the surface 23 at the lower end of such leg. When the coupling member 20 is attached to the pipe bowl ID, as shown in Figure 4, the hemispherical recesses I9 and 23 register and form a substantially spherical filtering or trap chamber, see Figure 5. The lower end of the leftleg 3|, Figure 3, registers with the port I8 of the bowl In in assembly. Near the top of the recess 33 a smoke port 34 is provided, and the port 34 leads from the recess 33 into the main smoke passage 35 of the stem portion 2|. The smoke port 34 communicates with the top of the recess 33, as stated, and is inclined downwardly therefrom to connect with the smoke passage 35, see Figure 6. The port 34 is at an angle to the smoke passage 35, with respect to both the vertical and horizontal, see Figures 6 and 7.
The pipe is provided with the usual detachable stem or mouthpiece 36 having a central smoke port 31, in communication with the smoke passage 35.
The use and function of the smoking ipe is as follows:
When the pipe is assembled as shown in Figure 1, it is used in the same manner as any conventional smoking pipe. The combined filter member and wedge 22 with the tongue 25 coact with the L-shaped recess in the pipe bowl, and prevent the leakage of any smoke at that point. There is a wedging action at both sides 24, at the top 28, and at the sides 21 of the tongue 25, and this Wedging action effects a good smoke seal. It should be noted that there is no tendency for the pipe bowl ill to become disconnected from the pipe stem if the user should invert the pipe and tap the open end of the bowl against his hand or another object, as is customary when removing burnt tobacco from the bowl. This tapping action tends to tighten, rather than loosen the wedged connection between the bowl and coupling member 20. However, when it is desirable to take the pipe apart for cleaning the bowl l may be readily disconnected from the coupling member without any tapping and without injury to the pipe.
When the pipe is smoked, the smoke is. drawn from the bottom of the chamber ll through the port l8. Such smoke then enters the U-shaped groove 30 and passes completely around the same, and into the spherical trap chamber formed by the recesses I9 and 33. During this travel through the extended passage, a large part of the nicotine in the smoke is filtered from the same, and most of the moisture present is deposited in the U-shaped groove 30 and spherical trap chamber. The remaining clean dry smoke leaves the spherical trap chamber via the smoke port 34, and passes from that port into the main smoke passage 35. An important feature resides in the fact that the angular smoke port 34 communicates with the spherical trap near the top of the same. This prevents the drawing off into the mouth of the smoker any of the fluid which is condensed and collected in the bottom of the spherical trap chamber.
When after continued smoking it is necessary to clean the pipe, it is necessary only to disconnect the pipe bowl from the coupling member 20, at which time the U-shaped groove 3|] and hemispherical recesses l9 and 33 may be conveniently wiped out. This cleaning may be done even while there is burning tobacco in the chamber I I.
It is thus seen that the invention provides an extremely simplified construction which is very ccnvenient, and which dispenses with the necessity for separate filter elements in the stem of the pipe. The groove 30 and spherical trap chamber provide efficient means for cooling the smoke and for removing the moisture and nicotine therefrom.
It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and. that various changes in the shape, size, and arrangement of parts may be resorted to, without departing from the spirit of my invention or the scope of the subjoined claims.
