A 7" TORNEY Patented Jan. 16, 1934 UNITED STATES PATENT oFncr-i SMOKERS PIPE Louis T. Watry, West Allis, Wis.

Application May 12, 1932. Serial No. 610,877 4 Claims. (01. 131-12) This invention relates to smokers pipes and more particularly to a cleaning feature adapted to be used with a pipe. 1

It is an object of the present invention to provide a pipe having a readily removable absorbent incorporated between the bowl and the stem to remove moisture issuing from the tobacco towards the stem. I

It is a further object of the present invention 19 to produce a pipe which may be easily cleaned and which will give a dry smoke.

A further object of the present invention is to produce a pipe which will cool the smoke before the smoke reaches the mouth of the smoker.

In pipes heretofore designed to dry the smoke previous to it reaching the smokers mouth, an absorbent material has been placed in the path of the smoke and the smoke drawn through it. This has produced a hard drawing pipe, besides presenting difiiculties in the cleaning of the pipe and the replacing of the absorbent material.

It is, therefore, an object to produce a pipe giving a perfectly dry smoke, in which the necessity of drawing the smoke through the absorbent is eliminated, and which will admit of ready replacing of the absorbent material.

These and other objects, the nature of which will become apparent upon consideration of the following description, are accomplished by means of a pipe such as illustrated in two preferred forms shown in the drawing and which are described in the accompanying specification, the

invention residing in the particular combination of elements set forth in the appended claims.

In the drawing:

Figure 1 shows a device embodying the present invention, being a cross sectional elevational view thereof;

Figure 2 is a cross section on the line 2--2 of Fig. 1, looking in the direction of the arrows;

and

Figure 3 is a view similar to Fig. 1 of a modification of the invention.

Referring to the accompanying drawing in which like numerals indicate like parts throughout the several views, the pipe comprises a bowl 10 and a stem 12, the bowl having an aperture 15 therein adapted to be filled with tobacco or other similar combustible material suitable for 0 smoking.

The bowl 15 has a counterbore 17 of larger diameter drilled from the bottom of the bowl 10 and substantially concentric with the bowl 15, a shoulder 18 being formed between the bowl 15 and the bore 1'7.

A screen 20 having a mesh sufliciently fine to retain the tobacco within the bowlv 15 and of sufficient rigidity to resist deformation due to pressure in packing the tobacco in the pipe, fits on the shoulder 18 and is held in place" by a substantially conical funnel 22, the funnel 22 being provided with a cylindrical opening 23 in the vertex end of the cone.

Referring to Figs. 1 and 2, a cup-shaped member 26 having a flat plate 26' with a concentric 86 aperture therethrough, fits over the cylindrical extension 23 and is attached thereto by soldering or other suitable means. The cup-shaped member has a downturned peripheral flange 28 which fits within a cap, generally designated 30, the cap 30 serving as a closure for the lower end of the counterbore 1'1.

The cap 30 is roughly cup-shaped and may comprise a base plate 32 provided with a knob 33 to facilitate removal thereof and an upstand- 78 ing cylindrical flange 35. The flange 35 terminates in a plurality of fingers 36 having a bead spun about the circumference thereof to fit in a corresponding groove 3'7 in the pipe.

A plurality of instruckbeads 38 are formed about the periphery of the flange 35 and support the cup-shaped member 26 and funnel 22, the

members

26 and 30 cooperating to form an enclosed chamber39 into which smoke may enter from the bowl 10 through the extension 23 of the funnel.

One or more pieces of absorbent material 40. such as ordinary blotting paper, are placed within the cup-shaped cap 30 so that smoke drawn through the funnel 22 and the cylindrical extension 23 impinges on the absorbent paper 40 to remove the moisture therefrom.

The smoke entering through the funnel 22 into the cup-shaped cap 30 escapes through apertures 44 in the plate 26' into a bore 45 in the stem 12 of the pipe. From the bore 45, the smoke enters the mouthpiece (not shown) and thence to the mouth of the smoker.

In smoking the pipe, smoke is drawn downwardly through the hollow bowl 10 and the screen 20 through the suction applied to the stem 12. The downward force of the smoke through the funnel 22 and the cylindrical extension 33 causes all of the smoke and particularly the heavy moisture within the smoke to continue 1 its downward travel due togravity and the inertia of the moving mass of smoke and moisture to impinge upon the blotting paper or absorbent 40. The blotting paper 40 is preferably made of any common blotting paper so that when 1 moisture impinges on it, capillary action takes place to draw the moisture into it. Thus, all the moisture is extracted from the smoke and a dry smoke is drawn through the apertures 44 to the mouth of the smoker, without having the smoke pass through the absorbent material.

-The smoke, in travelling from the bowl 15 to the stem contacts the screen 20, funnel 22, the cylindrical extension 23 and the cap 26. By making these members of heat absorbing material, such as aluminum or copper, a large portion of the heat may be withdrawn from the smoke previous to reaching the mouth of the smoker. By these means, the smoke is not only dried in its passage through the pipe, but is effectively cooled to give a cool dry smoke, which completely eliminates bite incident to smoking an ordinary pipe.

The modification shown in Fig, 3 is similar to that shown in Figs. 1 and 2, except that the cupshaped member 26 is replaced by a disc member 50 having apertures 52 therethrough. The disc 52 is attached'to the conical member 22 through a central aperture in the disc. The disc rests directly on top of the fingers 36, forming an en-= closed chamber53 similar to the chamber 39 into which all smoke from the bowl 10 enters and impinges on the blotting paper 40 to have moisture removed therefrom.

The closure cap 30 may be made the same in both constructions with a plurality of slots 55 lending resiliency to enable the peripheral bead 36 to spring inwardly into position in the groove 38.

It will be noted that the fiat plate 26' may be replaced by a conical member, if necessary, to bring the outer edge thereof below the stem 45.

When it is desired to clean the pipe, it is necessary only to remove the cap 30 and remove the blotting paper 40 and replace them with clean blotting papers. Practically the entire moisture in the tobacco smoke is deposited on the blotting papers 40 due to the proximity of the lower edge of the cylindrical extension 23 of the cone 22 to the blotting paper. Periodically, the cone 22 and screen 20 may also be removed for cleaning.

Having thus described the invention, it will be realized that there has been provided a relatively simple pipe adapted to both cool and dry the smoke in its passage through the pipe and it will be realized that the invention is susceptible to various changes and modifications coming well within the scope of one skilled in the art, and it is not, therefore, desired to limit the invention to the precise forms herein shown and described, but only by the scope of the appended claims.

What is claimed as new and desired to secure by Letters Patent is:
