PIPE.

Specification of Letters Patent.

Patented April 24, 1906.

Application filed July 12. 1905- Serial No. 269,280.

To all whom it may concern.-

Be it known that I, CHARLES ELKIN, a ci-tizen of the United States, residing at New York, in the county of New York and State of New York, have invented or discovered certain new and useful Improvements in Pipes, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has for its object to provide a tobacco-smoking pipe of such construction that the smoke drawn from the bowl of the pipe will be well cooled by the time it reaches the mouth of the smoker, so that the disagreeable and injurious efiects resulting from the impact of hot smoke against the tongue or other parts of the mouth of the smoker will be altogether avoided.

The invention comprises certain improvements on the pipe covered by United States Patent No. 767,804, granted August 15, 1904.

The present improved pipe preferably comprises three or more smoke-coolin chambers, arranged, as hereinafter set fort in the smoke-passage of the pipe and each of which chambers has a contracted inlet, so that a cross-sectional area of each of said chambers is of very much greater extent than the area of the inlet thereto, and thus as the smoke is drawn to each of the cooling-chambers it will be cooled by rarefaction, as also by a more or less whirling or tumbling efiect to which it will be subjected in each of the saidchambers.

In the accompanying drawings, Figure 1 is a sectional view of a pipe embodying the present invention, and Fig. 2 illustratesa modification thereof.

Referring to the drawings, a denotes the bowl of the pi e, in the stem portion a of which is forme the chamber 1), communicating by a contracted passage-way or duct 0 with the chamber of the bowl. The chamber 1) is preferably a straight bore, such as can be made with an ordinary drill or bit, and the passa e-way or duct 0, which intersects the charm er I) at an acute angle, is preferabl so inclined and located that it can be made y a drill inserted from the upper or outerend of the chamber 5. In other words, the extended line of the passage-way 0 will be within the walls of the upper or outer end of the oham ber b.

The stem proper, Z, of the pipe has a contracted inlet :1, opening into the upwardl -expandin ber w ch communicates with the passagesmoke-cooling or rarefaction c amway leading to the final smoke-cooling or rare action chamber g, having a contracted inlet h. The walls of the chamber 6 are preferably made as thin as is practicable, so that the rarefied smoke in said chamber will be cooled as much as possible from the cooler outside air, and thus these cooler Walls will act as a condenser and a deposit of injurious substances, comprisin percenta es of nicotin and oxalic acid, will be formed on said walls and will run down into the chamber b, from which it may be readily removed by taking out the pipe-stem Z. The final smoke-cool ing chamber 9 is preferably formed in a removable cap provided at its upper side only with smoke-exit'holes i, and in this respect the present pipe is like that covered by United States Patent No. 7 67,804, above referred to, although the form of this chamber g, as also the form of the tip 7' to which the cap "L, screwed or otherwise attached, may be somewhat varied, although the tapered. extreme end of said tip is preferred.

The stem of the pipe is preferably provided just forward of its mouth piece or tip with an air-inlet hole k, whichis sufficiently near the mouthpiece, so that it may be covered by the lip of the smoker, if desired, or may be left open for the entrance of a small amount of air to cool thesmoke. The stem of the pipe is also preferably provided at its lower portion, above the chamber 6, with a second air-inlet hole m, which, at the pleasure of the smoker, may be left open for the entrance of air to cool the smoke or may be covered by the finger of the smoker, as is deemed preferable. In use, however, it will be found advantageous to leave one, or both, of the airinlet holes m open for the ingress of a small quantity of air to cool and dilute the smoke, and thus augment the cooling effects roduced by the three rarefaction or coo ing chambers b, e, and g. The chamber 1) also serves as a trap, as will also the chamber 9, so

that nicotin and other injurious deposits from the smoke will-be safely excluded from the mouth of the smoker. The chamber g, having smokeexit orifices only in its upper wall, will receive little or no saliva from the mouth of the smoker, and thus clogging of the smoke-passage in the ipe-stem from this cause will be avoided. T e chamber e is u wardly expandin or of inverted conical form.

In the modifie form of the invention illustrated in Fi 2 an additional cooling or rarefying cham er is provided by the stem-secaltogether tion 0 between the chamber 1) in the stem part of the bowl and the chamber 6 in the pipe-stem proper, Z, this additional cooling or rarefying chamber preferably comprising the conical or tapered part p and the globular part 9. Still other cooling or rarefying chambers might be added, if desired, as will be understood, without departing from the essence of the invention.

In the use of the pipe constructed with three or more rarefaction or cooling chambers, as herein described, the hot smoke, which when it first issues from the chamber of the bowl is at a temperature of approximatelyAEOO Fahrenheit, will be, according to the temperature of the outside atmosphere, so cooled that when it finally issues 1nto the mouth of the smoker it will be reduced to a temperature near or below 90 Fahrenheit, and thus the injurious and disagreeable efi'ects resulting from the reception of hot smoke into the mouth of the smoker, and particularly against the tongue, will be avoided. This result is due partly to the rarefaction of the smoke in each of the cooling-chambers, in which most of it is momentarily detained and more or less whirled about, andpartly due to the cooling effect of ,the air entering one or both of the inlet orifices or holes is m.

Having thus described my invention, I claim and desire to secure byLetters Patent 1. A pipe having the stem of its bowl portion provided with a smoke-cooling straightbore chamber 6 and with a contracted passage-way or duct 0 intersecting said cham-- her 6 above the bottom of the latter, said pipe having a stem in which is formed the upwardly-expanding or conical chamber 6 with a contracted inlet, and the mouthpiece of said stem having the chamber 9 with smokeeXit orifices at its top only.

2. A pipe provided in the smoke passage- Way between the chamber of the bowl and the smoke-discharge outlet at the mouth piece with three or more smoke-cooling or rarefaction chambers each having a contracted inlet, one of said chambers being formed in the stem portion of said bowl, one, at least, of said chambers being formed in the stem proper of the pipe, and one at the mouthpiece or smoke-exit end of the pipe.

3. A pipe provided in the smoke passageway between the chamber of the bowl and the smoke-discharge outlet at the mouthpiece with three or more smoke-cooling or also the air-inlet hole m rarefaction chambers each having a contracted inlet, one of said chambers being formed in the stem portion of said bowl, one, at least, of said chambers being formed in the stem proper of the pipe, and one at the mouthpiece or smoke-exit end of the pipe,

formed in the stem portion'of the bowl, one,-

at least, of said chambers being formed in the stem proper of the pipe, and one at the mouthpiece or smoke-exit end of the pipe, the stem of said pipe being provided at its at the mouthlower part or adjacent the saidbowl with an I air-inlet hole, and said stem having also an air-inlet hole adjacent the said-mouthpiece. 5. A pipe having the stem of its bowl portion' provided with a smoke-cooling straightbore chamber 5 and with a, contracted passage-way or duct 0 intersecting said chamber 6 above the bottom of the latter, said pipe having a stem in which is formedthe up:

wardly-expanding or conical chamber 6 with a contracted inlet, and the mouthpiece of said stem having the chamber g with smokeexit orifices at its top only'and the said stern being provided, adjacent said mouthpiece, with an air-inlet hole r 6. A pipe having the stem of its bowl portion'provided with a smoke-cooling straightbore chamber 6 and with a contracted passage-way or diict c intersecting said chamber 6 above the bottom of the latter, said pipe having a stem in which is formed the upwardly-expanding or conical chamber e with a contracted inlet, and the mouthpiece of said stem having the chamber 9 with smokeexit orifices at its top only, and the said stem being provided, adjacent said mouthpiece, with an air-inlet hole 70, and sail stem having adjacent the bowl portion of the pipe,

In testimony whereof I affix my presence of two witnesses.
