TOBACCO PIPE.

Application filed November 3, 1924. Serial No. 7437,419.A

To all whom t may concern.'

Be it known that I, JASPER VVHITING, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Tobacco Pipes, of which the following is a specification.

This invention relates to pipes of the character used in smoking tobacco.

It. is the general object of the invention to devise a pipe which will afford a cool clean smoke, which can be readily cleaned, and which shall be so constructed as to prevent the tobacco in the bottom of the bowl from becoming wet and soggy. It is an especially important object of the present invention to devise a smoking pipe in which the draft can be regulated. lVhile the invention is especially concerned with pipes, many of the features thereof are also applicable to cigarette and cigar holders.

The nature of the invention will be readily understood from the following description when `read in connection with the ac Referring rst to Fig.l, the pipe there shown comprises a bowl 2 having an integral stem 3 projecting laterally therefrom. This stern is drilled to form a relatively large bore 4; which is connected with the bottom of the bowl 2 by a short throat or passage 5. A mouth piece 6 of a common form is removably secured to the outer end of the stem 3 by means of a reduced shank 7y which fits frictionally within the bore 4.

The hole 8 through this mouth piece and the passa e 5 are both made abnormally large so t at these holes, together with the bore Ll, permit an excessive draft. Preferably the hole 8 is slight-ly tapered as clearly shown in the drawings. In the common forms of pipes the draft or pull is deteiimined by thesize of the hole or holes through which the smoke passes, these holes being made sufficiently small in diameter to produce satisfactory .results rIn the pipe shown the holes or passages are so large that an excessive draft is permitted, as just stated, but the draft may be regulated by theadjustmentdof a split pin 9, best shown in Fig. This pin is very similar to a cotter pin and it may be made of metal, bakelite, glass, hard rubbeigor any other suitable material. When metal is used a non-corroding metal shouldbe selected, or thepin-Inay be made of steel heavily plated with nickel. In any event, the legs of the pin are so made and designed that they tend to jspringapart so that when the split end of the pin is inserted in the hole 8 it will be frictionally held in any position of adjust-,K

ment longitudinally ofthe hole by its engagement with the walls thereof.

As is well known the flow or draft of It will be evident that i area and'its length increased. When the pin y ismovedinlthe,opposite direction the draft isV increased, or, 1n other words, the pull is made casier and the pipe smokes more freely.

The smoker thus can regulate the draft to make thewpipe more or less free smoking, as vhe may'desire at any time. Preferably the legs of the pin 9 are tapered very slightlyin widthLthe free ends of the legs being y narrowerthan atk any other point in their length.

The large bore l forms a relatively large chamber in which the flow of smoke is retarded so that it is allowed to cool. Any moisture which otherwise would enter the bowl of the pipe through the mouth piece is also collected or trapped in this chamber and, consequently, the tobacco in the bottom of the bowl is prevented from becoming wet and soggy. The entire charge of tobacco in the bowl thus burns even-ly until consumed and the ashes fall readily from the pipe when the smoke is finished. Furthermore, this trapping of the moisture prevents it from being drawn into the mouth of the smoker to his discomfort. The pipe may be very easily cleaned, as will be obvious, and the trap el is of such proportions that the pipe requires cleaning only at relatively long intervals. By inserting one leg of the pin 9 in either of the holes 8 or 5 these passages may be freed of any accumulations that cannot readily be blown out.

A somewhat different embodiment of the invention is shown in Fig. 2. In this construction the stem l() is made of metal tubing, preferably aluminum, this stem being joined to the bowl-ll by a ferrule l2 into which the stem is threaded. The mouth piece 13 is frictionally held in the outer end of the stem', as in the construction above described. This pipe also includes a split pin 9, constructed and mounted in the same manner as in the pipe shown in Fig. l and performig the same functions. This pipe affords even a cooler smoke than that shown in Figi since the metal stem l()v radiates heat more readily than the wooden stem 3.

rl`he invent-ion may be applied to practically any style of pipe, and, as above indicated, it is also applicable to cigarette and cigar holders. For this reason the term pipe is used in the appended claims in a genericsense to include cigarette and cigar holders.

Fig. et shows a cigarette holder embodying the invention. ln this device the "bowl l-l has an integral, stem 15 ext-ending therefrom to whichthe mouth piece 16 is connected by a screw joint. The relatively large hole 17 through the mouth piece permits an excessive draft, but this draft is reduced by the adjustable split pin 9 which restricts the flow of smoke through the holder.

In all of the constructions aboveshown the split pin 9, when made of metal, will absorb heat from the smoke and therefore reduce to some extent the temperature of the smoke. It will also be appreciated that the split pin can readily be cleaned by withdrawing it from the mouth piece andA wiping it with paper or cloth, at which time,

also, the stem or mouth piece can be cleared of any accumulations.

Thilo l have herein shown the best embodiment of my invention that l have so far devised, I do not wish to be limited to the exactdetails of the construction shown.

Having thus described my invention, what I desire to Lclaim as new is:

l. A pipe comprising a bowl, a stem projecting therefrom, a mouthpiece at the end of said stem, said stem and mouthpiece having abnormally large smoke conducting holes therethrough whereby an excessive draft is permitted, and means stationary while in operation but adjustable to regulate the draft through said holes.

'2. A pipe having a stem with a mouthpiece at the end of said stem, said stem and f mouthpiece having holes therethrough forming a passage for smoke, and a device -for regulating the draft through said passage, said device being stationary but being adjustable to regulate said draft.

3. A pipe having a stem with a mouthpiece at the end of said stem, said stem and mouthpiece having holes therethrough forming a passage for smoke, and a device in said passage for regulating the draft therethrough, said device being stationary but adjustable longitudinally in said passage to vary the draft.

4. A pipe having a stem with a mouthpiece at the end of said stem, said stem and mouthpiece having holes therethrough forming a passage for smoke, and a stationary device adjustable in said passa-ge and frictionally held in its adjusted position for regulating the draft through said` passage.

5. A pipe having a stem with a mouth piece at the end of said stem, said stem and mouth piece having holes therethrough for the passage of smoke, and a split pin adjustable longitudinally in one/ofnsaid holes, the legs of said pin tending to spring apart wherebythe pin is frictionally held in its adjustedI positionby its contact with the walls of the hole.
