SMOKING PIPE Filed Oct. 9, 1931 INVENTOR Patented Feb. 14, 1933 UNITED STATES JOHN P. MARTIN, OF PITTSBURGH, PENNSYLVANIA SMOKING PIPE Application filed October 9, 1931. Serial N0. 567,803.

This invention relates to smoking appliances, particularly tobacco pipes, but may also he applied to other types of smoking tubes such as cigar holders and cigarette holders. I

According to my invention, I provide a bit or mouthpiece that prevents or retards saliva from the mouth of the smoker, entering the smoke passage of the stem, also to prevent or retard condensate that may collect in the smoke passage 01": the stem from being drawn into the mouth of the smoker.

The invention provides, moreover, a stem of unique shape which will give the smoke passage of large cross section in a given stem and at the same time provide a wide flattened surface at the bit end, which stem will have a pleasing and serviceable contour. In addltion, the invention provides a bit that will discharge smoke laterally and far removed from tip of tongue. Such construction in conjunction with the wide flattened surface of stem make it most unlikely that the smoker will have a sore tongue from the use of the pipe.

By providing a stem having the large size of smoke passage a cooling effect on the smoke is obtained by the fact of the smoke mixing with a much larger body of air within the smoke passage and also by coming in contact with a larger area of smoke passage wall, than in the ordinary stem.

The ordinary smoking pipe is so constructed that the smoke is discharged into the mouth always at practically the same location notwithstanding the fact that the pipe may be moved from one side of the mouth to the other. The point of discharge is usually closely adjacent the tip of tongue. and the continued impingement of the smoke at this point plus the seepage from stem cause an irritation of the tip of the tongue. Moreover, the ordinary stem as now generally made, has a straight bit. A person having natural teeth finds no difiiculty in retaining bitin the mouth, but a person whose teeth have been removed or who is using artificial teeth has considerable dificulty in getting a sufiicient bite on the stem to permit the pipe to be held in the mouth unsupported by the hand.

A further disadvantage of the present day stem is the fact that the straight open end of smoke passage permits the flow of saliva into said passage Where it absorbs a condensible material from the smoke, resulting in the accumulation of a mass within the stem that partially or wholly stops the very small smoke passage after which it is drawn into the mouth of smoker, discharging on to the tip of the tongue causing what is frequently called a burned tongue.

Pipes have been devised having traps between the stem and the bowl for the collection of condensate and saliva, but such pipes do not prevent the entrance of saliva from the mouth into the stem, andlt is this saliva from the mouth that causes most of the trouble.

According to the present invention there is provided a smoking appliance having a bit so constructed that the smoke is discharged into the mouth cavity laterally instead of against the tip of the tongue, so that no lrritation is produced from this source. The bit is so constructed that the pipe may be readily retained in the mouth unsupported by the hand by a person having artificial teeth or having no teeth, and be more comsible smoke passage in a glven stem, makes it practically impossible for any saliva to enter the smoke passage of stem, or any condensate from smoke passage to be drawn into the mouth of smoker.

To secure the best practical results, I have so designed the stem shape and dimensions that it will admit of. the largest smoke passage possible in a given size stem, while at the same time it will present apleasing contour, and a wide flattened surface close to smokepassage has: rarely to be cleaned as ni 7 a a I .e a V -F1gure 2 lea slde y1ew"0f my nnproVed bit portion where teeth or gums engage stem tokeep stem from rotating. Also the large area of smoke passage hasa decided tendency to: cool the smoke because itimixes with the large body of air in smoke passage and also comes in contact with the much larger area of the walls of the, stemf Also the large nothing but condensate enters"it, which condensate in the absence of saliyaislvery little- The invention may be readily i understood ,by reference tothe accompanying drawing in which:
