Application February 24, 1942, Serial No. 432,101

1 Claim.

This invention relates to a novel smoke disperser for pipes or holders, whereby the smoke drawn from a pipe or cigar is so dispersed, when moving into the mouth of the smoker, that it will not impinge directly on the tongue of the smoker in a solid stream. The impingement of a solid stream of smoke on the tongue of a smoker causes irritation; whereas a dispersed or diffused mass of smoke does not cause as great an irritation.

A feature of my invention is to provide a novel and effective means of dispersing and diffusing the column of smoke which emanates from a pipe or holder.

Another object of my invention is to provide a novel smoke disperser which can be mounted or placed in the usual pipestem without materially departing from the usual or well-known construction of a pipestem.

Another object is to provide a novel pipe or holder, smoke disperser which is simple in construction, inexpensive to manufacture, and effective in operation.

A feature of my invention resides in the novel means of controlling a quantity of smoke which is drawn through the stem of the pipe or holder by adjusting my novel smoke disperser in the stem of the pipe or holder.

Still another feature of my invention is to provide a novel smoke disperser which can be efiectively cleaned when necessary.

Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detailed description and the appended claims.

In the drawing Figure 1 is a side elevation of a pipe, illustrating my smoke disperser in position in the stem of the pipe.

Figure 2 is a longitudinal, sectional view of my smoke disperser.

Figure 3 is an end view of the same.

Figure 4 is an enlarged end view of a pipestem, with my smoke disperser mounted therein.

Referring more particularly to the drawing, the numeral l indicates a pipe, which includes the usual pipestem 2. A bore 3 extends from the pipe bowl and through the stem in the usual and well-known manner for the purpose of drawing smoke from the pipe bowl as will be understood. In the outer end of the stem 2, I provide a smoke disperser 4, which comprises a tubular section 5 closely fitting within the outer end of the bore 3. A counterbore 6 extends through the member 5, and smoke is drawn through this counter-bore, as will be further described.

A tapered head I is integrally formed on the outer end of the member 5 and the tapered walls of this head are fitted in the outer end of the stem 2. A plurality of grooves 8 are formed in the outer tapered walls of the head 1, and these grooves communicate with the counter-bore 6 to provide a continuous duct through which smoke may be drawn. The stem 2 is provided with complementary grooves 9 which match the grooves 8 to provide a substantially tubular conduit or duct. By rotating the disperser 4 in the stem of the pipe, it is possible to misalign the grooves 8, 9, thus restricting or reducing the passage through which smoke may be drawn; and, therefore, reducing the amount of smoke which is drawn into the mouth of the smoker. A slot Ill, in the head 1, permits the disperser to be rotated as desired.

In operation the smoke is drawn through the bore 3 in the usual manner and passes through the bore 6 and the grooves 8, 9, thus drawing the smoke outwardly from the end of the pipestem, tending to disperse or difiuse the smoke and preventing the smoke from impinging upon the tongue of the smoker in a solid stream.

It is obvious that my smoke disperser can be used on pipes, cigar holders, or cigarette holders, if desired.

Having described my invention, I claim:

A smoke disperser for pipes comprising a tubular member, circular in cross section and of a diameter adapting it to fit snugly in the smoke passage of a pipe stem, a solid head at the outer end of said tubular member, said head being frustro-conical and tapered toward the tubular member for snug fit into a flared mouth of the smoke passage of the pipe stem, the bore of said tubular member being extended into the inner end of said head, the inner end of the head being formed with radially extending smoke outlet openings leading from the inner end portion of the said bore and spaced from each other circumferentially of the head with each opening in opposed relation to another one of the openings, said head being formed with grooves in its annular side surface xtending longitudinally of the head in spaced relation to each other circumferentially thereof from the outer end of the head to the junction of the head with the tubular member and at their inner ends communicating with outer ends of the said smoke outlet openings, and said head being provided with means for turning the smoke disperser and moving the grooves of its head intoand out of position to register with companion grooves formed in walls of the mouth of the smoke passage of the pipe stem.
