Application April 23,

1 Claim.

This invention relates to a class of articles adapted to be used by tobacco smokers and has particular reference to a tobacco pipe so constructed that it will readily prevent oily and solid constituents, such as nicotine and free carbon contained in tobacco, from reaching the mouth of the user.

A further object is to equip the pipe with means that will serve to effectively collect and absorb within the pipe the products of combustion.

Another object of the invention is to provide in the pipe, absorbent holding means which absorbent can be quickly and conveniently replaced by a fresh piece of absorbent after the original absorbent has served its purpose.

An additional object is toprovide inthe pipe construction a cooling chamber whereby the smoke drawn through the pipe may be readily cooled before reaching the smoker.

A still further object is the provision of a pipe of the character described which is economical to manufacture, simple in construction and highly efficient in use. I

Other objects and advantages will be apparent during the course'of the following description.

In the accompanying drawing-forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, I

Fig. 1 is a side elevation of a tobacco pipe having my invention applied thereto,

Fig. 2 is a longitudinal section of the arrangement,

Fig. 3 is a fragmentary plan view of a portion of the pipe barrel and mouthpiece,

Fig. 4 is a transverse vertical section through the barrel the view being taken on the line 4-4 of Fig. 2, and

Fig. 5 is a perspective view of the absorbent.

Great inconvenience has been experienced by pipe smokers due to the accumulation of nicotine and other juices in the pipe that often reach the mouth of the smoker. Furthermore when a pipe has been smoked for a considerable time the smoke often becomes heated with a resultant burning of the tongue of the smoker. The interior of the ordinary pipe is often diificult to clean due to the interior being inaccessible. To overcome these inconveniences I have provided means for readily absorbing the nicotine, means for cooling the pipe and means for permitting ready disassembling of the pipe so that access can be had thereto.

In the accompanying drawing wherein for the 1934, Serial No. 722,024

purpose of illustration is shown a preferred embodiment of my invention, the numeral 8 designates the bowl of the pipe which may be of any desired shape and size. Projecting angularly from the lower part of the bowl member is a tubular stem 9 that communicates with the bowl through the medium of a passage 12. This stem or barrel portion has a reduced extremity as indicated at 13, the purpose of which will be later described. Projecting from the passage [2 and extending into the tubular stem. is a tube [4. The said tubular stem defines a chamber 15, in which is positioned a piece of absorbent A conforming to the configuration disclosed in Fig. 7, which by virtue of its upper curved surface, will underlie the tube I4 so as to receive thereon any nicotine or foreign matter that may be drawn through the tube toward the lips of the smoker. In the open end of the barrel or stem there is detachably secured a mouthpiece [6 having a longitudinal bore I! provided therein that communicates with a cooling chamber I8 provided in said mouthpiece. In order that the correct location of the longitudinal bore may always be easily, determined by the smoker, I have provided on the upper surface of the mouthpiece adjacent its point of engagement with the stem portion, a circular knurled portion l9.

In the operation of the device, the tobacco to be smoked is first placed in the bowl and when lighted the smoke will be drawn through the tube I4 into the cooling chamber l8 thence out through the bore I! to the mouth of the smoker. Any products of combustion such as nicotine or other oily substances or in fact any foreign matter will be deposited on the absorbent A and by capillary attraction the said absorbent will readily absorb and extract from the tobacco the free carbon and the like, thus preventing all biting and burning sensations of the tongue of the person when smoking and realizing a cool smoke.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to. without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I claim:-

A smoking pipe comprising a bowl, a stem ex tending from the bowl and having a passage communicating therewith, said stem having a reduced outer end and a chamber therein extending from the outer end of the passage, a tube secured in the passage and extending therefrom for disposal in the chamber, a mouthpiece mounted on the reduced end of the stem and having a chamber at the inner end thereof communicating with the chamber of the stem, said mouthpiece having a bore extending therethrough at an upward inclination for disposing the inner end thereof in communication with the chamber of the stem adjacent to the outer end of the latter for arrangement above and substantially in registration with respect to the tube, an individual elongated concavo-convex strip of absorbent material mounted in and fitting the chambers with the concaved portion uppermost to underlie the outlet end. of the tube, said strip having its opposite ends contacting the end walls of the chambers to provide a trap, and an indicating means on the mouthpiece to determine the position of the inner end of the bore thereof whereby to dispose the same in proper relationship with respect to the tube.
