PLEASANT PUFF OVERDRAFT PIPE Filed Oct. 50. 1942 JOHN 3. SWAN.

Patented May 18, 1943 UNITED STATES PATENT OFFICE 2,319,756 PLEASANT PUFF ovEnnaAFr rrra John B. Swan, Gladstone, Mich. Application October so, 1942, Serial No. 463,960 1 Claim. (01.131-202) This invention relates to a pleasant puff overdraft pipe.

An object of the invention is the construction of a novel pipe whereby the user can enjoy a pleasant smoke, by reason of a novel absorbent device being used in the pipe, with means for causing the tobacco to burn with reasonable freedom, which altogether produces ideal results.

Another object of the invention is the construction of a novel absorbent device in a pipe, which will prevent objectionable juices or the like from being drawn into the mouth of the smoker or user.

A still further object of the invention is the construction of a novel overdraft pipe which is comparatively inexpensive to manufacture, efiicient in operation and of a long life.

With the foregoing and other objects in view, my invention comprises certain novel constructions, combinations, and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawing, and more particularly pointed out in the appended claim.

In the drawing:

Figure 1 is a view partly in elevation and partly in longitudinal section of a pipe constructed in accordance with the present invention.

Figure 2 is an enlarged sectional view taken on line 22, Figure 1, and looking in the direction of the arrows.

Figure 3 is a perspective view of the absorbent device, without the cheese cloth or cotton batten unit thereon.

Figure 4 is a plan view of a piece of cotton batten, while Figure 5 is a similar view of a piece of chee e cloth.

Referring to the drawing by numerals, in which drawing I have shown the preferred embodiment of my invention, I designates the bowl, which is provided with an integral laterally-extending neck 2. The bowl I is also provided with an inlet aperture 3, which permits air to be drawn into the bowl by the user, whereby the tobacco burns comparatively freely, without going out; so often smokers are annoyed by the fire or burning tobacco dying out, but this is practically eliminated in my improved pipe.

An overdraft tube 4 extends into the bowl I, the inner end of said tube terminating approximately one-eighth of an inch from the bottom or inner face of thebowl. The outer end of tube 4 extends into the neck 2 near its outer end. A detachable mouthpiece 5 has a reduced that registers with the outer end of overdraft tube 4, Fig. 1, whereby the smoke is drawn from thebowi into the mouthpiece through said overdraft tube 4. I

An absorbent device 8 is placed in the pipe, as clearly shown in Figure l, for the purpose of absorbing the moisture or juices that ordinarily collect in the bottom of a pipe. This novel absorbent device 8 comprises a coil spring body 9. the outer coil 10 being provided with a sharp impaling point II; the inner coil l2 terminates in an elongated integral handle l3, which handle is on a line with the central longitudinal axis of the coil spring body 9. This admirably places the handle in position to be easily inserted and centers in the mouthpiece 5, as.clearly shown in Figure 1. The elongated handle l3 terminates at its outer end in an integral elongated loop grip I4. When the mouthpiece 5 is detached from the neck 2 the operator can secure an eflicient grip on the absorbent device at It to remove the absorbent device, or to insert it, after it has been removed from the assembled position. I place an absorbent piece or sheet upon the coil spring body, such as cotton battin l5 or cheese cloth l6. The unit I5 or IE is best wrapped upon the coil spring body by imparting rotary movement to the body thereby impaling an end on the point II and then continuing rotary movement to the'body, thereby winding the sheet around lightly until enough has been wound on to fill the neck 2 of the pipe, then press all around the coilspring body 9 until the winding of the absorbent unit is pressed in between the coils; this presses down the wrapping so it comes nearly together, or entirely so, on the inside of the coil, making an excellent filter or absorbent. The impaling point II is near the center longitudinal axis of the body 9, whereby the absorbent unit I5 or I6 is admirably placed and held for the wrapping function. f

I plan on having preferably six of the absorbent devices 8 (Fig. 3) with each pipe sold, so

the smoker can take out his absorbent device or filter, every night, and by putting it in vinegar a few hours, it will rinse out easily. Therefore, the user of the pipe can have a clean absorbent device every day, at a very small cost and little effort.

he will obtain an ideal smoke.

While I have described the preferred embodiment of my invention, and illustrated the same in the accompanying drawing, certain minor changes or alterations may appear to one skilled in the art to which this invention relates, during the extensive manufacture of the same, and I, therefore, reserve the right to make such alterations or changes as shall fairly fall within the scope of the appended claim.

What I claim is:

. Asa new article of manufacture, an overdraft pipe provided with an absorbent device, said absorbent device comprising a body of a series of spring coils, said body having its outer coil parallel throughout its length with the other coils and terminating in a sharp impaling point 4 turned inwardly near the longitudinal axis in convolution with the rest of said coil, said body having its inner coil terminating in an integral elongated handle, said handle extending or centered with the longitudinal axis of said body, said handle provided at its outer end with a horizontal elongated loop grip, and an absorbent sheet impaled on said sharp point by rotating said body, whereby the sheet .is rolled around the whole of said body with portions of said sheet within spaces formed by said coils and also covering the exterior surface of said body. JOHN B. SWAN.
