SMOKING PIPE Filed Oct. 27, 1936 2 Sheets-Sheet 2 Inventor Cfl Fkeer Patented Dec. 7, 1937 UNITED STATES PATENT OFFICE 1 Claim.

This invention has reference to improvements in tobacco smoking pipes and the principal object of the invention is to provide means for extracting the moisture from the tobacco within the pipe bowl and preventing same from entering the stem of the pipe, thereby to obtain a cool and dry smoke.

Other objects of the invention are to provide a moisture absorbing device capable of attachment to any pipe with the minimum requirement of changes in or alterations of the pipe structure and which provides for easy replenishment of the absorbent unit.

In addition, the device provides for the economical use of tobacco by a more complete consumption of the quantity contained in the pipe bowl, particularly at the lower end or heel thereof.

The above objects are attained by the novel construction and arrangement of parts hereinafter more fully described with reference to the accompanying drawings, wherein:

Figure 1 is a plan view of a tobacco pipe embodying the features of the invention.

Fig. 2 is a side elevation of the pipe.

Fig. 3 is an end elevation of the pipe as viewed from the front or outerside of the pipe bowl.

Fig. 4 is a vertical central section through the pipe bowl and stem with the moisture absorbing unit shown in elevation, the section being taken on line 4--4 of Figure 1.

Fig. 5 is a transverse section through the pipe bowl, on line 5-5 of Fig. 2.

Fig. 6 is a detail perspective view of the holder or tray for the absorbent pad, and

Fig. 7 is a detail View of the absorbent pad.

In the drawings, 1 indicates the bowl of the pipe, from one side of Which extends the stem 9 having a smoke passage I I extending between the cavity of the pipe bowl and the outer end of the 40 stem which is counterbored at I3 to receive the reduced end of the tubular mouthpiece I5. For the purposes of the present invention, the pipe bowl is made with a rather heavier bottom I? than usual, which is provided with a short bore I9 opening inwardly of the pipe bowl from the point on the side thereof directly opposite, or nearly so, the pipe stem 9. The bore is of such a diameter as to result in the cutting away of a part of the bowl bottom so that communication between the cavity of the bowl and the bore I9 is established in a manner clearly apparent from the drawings. The length of the bore is such that its inner end is separated from the smoke passage I I of the stem by a substantially narrow intervening portion 2I of the pipe body. In the cross sectional contour, the bore I9 may be elliptical, circular, or of any desired shape. In the accompanying drawings, the bore I9 is shown as being elliptical in shape and is in a lower plane than the inlet orifice of the pipe stem smoke passage I I, due to the fact that, in the present invention, the latter passage extends concentrically of the pipe stem only up to a point approximately one-half inch from its entrance into the bowl cavity at which point it is angularly offset, as shown at 23, to enter the bowl cavity at approximately one-eighth inch above and the same distance from the inner end of the bore I9.

A holder or tray of metal or composition is shaped to fit exactly inside of the bore I9 and is of full circumference only at one end 25 and for a distance equal to the thickness of the wall of the pipe bowl, to have a frictional fit therein. The annular portion 25 of the holder is closed on its outer side by an end plate 21 of larger diameter than said annular portion for abutment against the side wall of the pipe bowl. Beyond the open end of portion 25 the holder is reduced to half the circumference with its outer end open to provide a trough 29, endwise of which a pad 3| of absorbent material is placed and pushed up against the end of plate 21; the pad being of a size to completely occupy the holder in the manner illustrated in Figs. 1, 4 and 5. The pad 3| is composed of calcite, calcium carbonate, or other absorbent mineral or composition which is covered spirally with a light layer of absorbent paper or other suitable absorbent material. When the pad is saturated, the holder is withdrawn from the bore and a fresh pad substituted for the used pad.

When the parts are placed in proper relative position as depicted in Figs. 1, 4 and 5, the absorbent pad projects into and forms part of the bottom of the tobacco receiving cavity of the pipe bowl and absorbs from the tobacco the moisture tending to collect at the bottom or heel thereof. Not only is the tobacco thereby kept dry but the objectionable juices or moisture therefrom is prevented from being drawn into the smoke passage of the stem by reason of the fact that the inlet orifice 23 of the smoke passage is remote from and above the absorbent pad. The pipe stem is thus kept dry and a cool smoke is obtained.

The device is economical also in that the elimination of the wet heel at the bottom of the tobacco provides for the freer burning and greater consumption of the latter within the pipe bowl, so that there is more tobacco per pipe full to smoke. The holder may be made to match the color and shape of any size pipe holder.

Having thus described the invention, what is claimed is:-

A tobacco pipe comprising a bowl having a stem extending from one side thereof adjacent the bottom of the bowl cavity, the portion of said bowl which defines the bottom of the cavity being of substantially thick cross section and provided With a short bore leading inwardly to the cavity from a point on the side of the bowl substantially 10 in axial alinement with the said stem and trav-
