Application December 11, 1946, Serial No. 715,421

This invention relates to a tobacco pipe and more particularly to an improved construction therefor providing a clean, cool smoke.

It is an object of the present invention to provide an improved pipe of this nature in which a long path of travel for the smoke is provided without increasing the length of the pipe and, at the same time, may be readily cleaned and which also provides an attractive appearance.

Another object is to provide a pipe of this lcharacter having a two-part bowl which may be instantly disassembled for cleaning and which, at the same time, provides a reliable seal between the two bowl parts.

Figure l is a perspective view of a pipe embodying a preferred form of the present invention.

Figure 2 is a top View partly in section.

Figure 3 is a vertical sectional view through the bowl of the pipe taken along the line 3-3 in Fig. 2.

Figure e is a sectional view taken along line 4 4 in Figure 2.

Referring now to the drawing, the improved pipe comprises a base member Ill of cylindrical form and having a flat bottom surface and which together with a tubular member I2 form the bowl of the pipe. The base member I3 may be of plastic, metal or wood and has permanently secured on the upper face 24 thereof a cap member I4 preferably made of wood although it may be of plastic or metal as well. Cap I i is provided with a central recess 25 on the bottom side thereof. The tubular member I2 is formed preferably of wood and is provided with a slightly curved bottom surface IB and a recess I8 of annular form. Inwardly of the recess I8 is an annular shoulder 2li which coacts with a gasket 22 which rests on the fiat surface 24 of the base member I0. The ilat surface 24 is spaced from and below cap member I4 and provides a wall which lcloses the lower open face of recess 25. Rigidly secured to the base I in any suitable manner is a crown spring 26 adapted to t in the recess I8 and to engagethe curved surface 28 formed in the outer side wall of the recess I8.

The stem of the pipe is formed as three tubes, 3B, 32 and 34, which extend horizontally through corresponding apertures in the base member I0 and are arranged side by side in a common horizontal plane. The central tube 32 connects with the base member through the medium of an `aperture 36 through the wall 24, recess 25 and an annular series of small holes 31 in cap member I4 while the outer tubes 33 and 34 are imperiorate. The tubes extend forwardly of the bowl 2 Claims. (Cl. 131-186) Where an externally ribbed return bend tting orv cap 38 preferably formed of plastic is slidably telescoped over a sleeve 39 secured to the ends of the tubes. The tting 38 is provided with a U-shaped internal chamber or passage 43 connecting the ends of the two outer tubes 33 and 34, and a centrally located projection 48 which plugs the center tube 32. The end of tube 3G communicating with passage 4I! is provided with an extension 5B having an upwardly disposed opening 52 which serves to admit only smoke, the chamber 43 acting as Ia trap for any fluid which might accumulate in the passages. A gasket 5I forms a seal between the iree end of sleeve 39 and the adjacent face of cap 38. To the rear end of the tubes there is secured a metal retainer or sleeve 54, similar to sleeve 59, into which a bit 42 is adapted to be slidably telescoped. The bit is held within the retainer by means of a snap spring 56 which projects through an opening in the retainer and which is adapted to be depressed for disengagement. The bit is also provided with an offset smoke passage 44 communicating with tube 30 and with a U-shaped passage 43 which connects tubes 32 and 34.

In operation it will be seen that smoke is drawn in through the small holes 3'I which act as a screen for tobacco particles, then through recess 25 and aperture 36 and must traverse rst rearwardly through the tube 32, then across the passage 46 to the tube 34, thence forwardly to the passage 43 and rearwardly again through the tube 30 and passage 44. The tubes 33, 32 and 34 are preferably formed of aluminum or other high heat conductive metal so that the smoke is cooled by radiation of heat. At the same time, the tubes are straight and free of obstruction so that they may be readily cleaned by slipping the bit 42 and the return bend fitting 38 out of telescopic engagement with the sleeves 54 and 39, respectively. Likewise, the bowl may be readily removed for cleaning which particularly facilitates cleaning the top surface of cap I4. In fact, a smoker may have extra removable bowl members I2 and alternate them so that one may be permitted to dry and air out while another one is being used on the pipe. The open construction of the stem with the three tubes side by side present a pleasing appearance and, at the same time, makes for maximum heat radiation and thus provides a cool smoke.

I claim:

1. In a tobacco pipe of the type comprising a stem and a two-part bowl, said bowl comprising a base member and a tubular member open at its upper and lower ends and throughout its axial extent, said base member being apertured along an axis perpendicular to the axis of the tubular member to receive said stem therein, said base member having a portion dening a top wall which forms a tobacco-supporting surface, the periphery of which is spaced inwardly of the periphery of said base member, the periphery of said top wall corresponding in size and shape with the opening at the lower end of said tubular member, said tubular member being arranged on said base member with its lower end telescoped around said top wall, said base member having a recess below said top wall and said top wall having a plurality of openings therein cornmunicating with said recess, said stem extending into said apertured portion of said base member to a point below said recess, and means forming a passageway in said base member extending downwardly from said recess and into said stem.

2. In a tobacco pipe of the type comprising a stem and a two-part bowl, said stem comprising a plurality of generally straight tubular elements arranged side by side in a single fiat plane whereby said stem can be comfortably and securely held between the users fingers, said bowl comprising a base member and a tubular member open throughout its axial extent and adapted to be detachably supported on said base member, said base member having a substantially at bottom face and said tubular elements comprising said stem extending through said base member and projecting outwardly from diametrically opposite sides thereof in a plane parallel to said ilat bottom face of said base member whereby the pipe can be supported in an upright position 4 on a generally at supporting surface, said base member having an inlet opening at the top thereof and at least one of said elements of said stem being open within said base member and communicating Iwith said inlet opening of said base member, said tubular elements being open at opposite ends thereof, a bit member telescopically arranged over said open ends of said tubular elements remote from said bowl, and a cap member telescopically engaged over the other set of ends of said tubular members, said bit and cap connecting the passages of said tubular elements in series.
