2 Claims.

The invention relates in general to a smoking pipe of the multi-chambered stem type and the invention .specifically relates to an improvement in the stem element or stem inserts which define More specifically identified, the invention relates to that type of pipe stem which is providedadjacent the bowl with a chamber for receiving smoke from the bowl and incidentally tr'ap therefrom the oily and tarry tobacco condensate juices, hereinafter referred to as the oil trap or condensing chamber, and from which chamber smoke is drawn into a smoke cooling chamber in or adjacent the bit end of the stem and wherein the smoke is permitted to circulate before being withdrawn and into which is discharged any saliva or mouth moisture from the smoker.

The primary object of the invention is to provide an improved and simplified form of pipe of the type outlined which will be maintained sweet while in use; which can be easily cleaned; and particularly from which the trappedjuices, either those from the tobacco bowl or those from the mouth of the user, may be readily and quickly drained from time to time as may be necessary.

"The present disclosure particularly features the formingof the stem in sectional parts which may be readily separated from eachother and when separated provide exposed, easily cleaned surfaces which can be scoured with the ordinary pipe cleaners.

Smoking pipes as now generally constructed become objectionable largely because the briar wood-of which they are usually constructed readily absorbs the oily and tarry tobacco condensate and give rise to what is commonly referred to as.

a strong pipe. It has been suggested heretofore to line the condensing chamber of such pipes with some form of metal liner and which, of course, acts to prevent the contamination of the wood, but as heretofore constructed, these metal lined chambers have been designed to permit the smoke to pass therefrom but have not been provided with any means to facilitate the cleaning of the same whenever it is desired to discharge the pipe of its accumulated juices.

Accordingly, another object of the invention is to provide as part of the stem insert, a combined funnel and pouring nozzle which will permit and facilitate the emptying of oils from the condenstion of the accompanying drawing and in part will be more fully set forth in the following particular description of one form of pipe embodying the invention, and the invention also consists in certain new and novel features of construction and combination of parts hereinafter set forth and claimed.

The accompanying drawing is a view in vertical axial section through a tobacco pipe illustratinga preferred embodiment of the invention.

Referring to the drawing, there is disclosed a tobacco bowl Ill provided with a tobacco chamber I I and an integrally extending neck 12 forming the inner end of a stem [3, the outer end of which stem is formed by means of a bit M. The bit is provided with a plug end l5 forming a tenon telescoping in the open end of the neck l2 to form a two section stem.

The neck is provided with a bore extending therethrough which comprises an enlarged outer cylindrical portion ll terminating at its inner end in a wall l8 through which extends a relatively constricted portion IQ of the neck bore and opening into the bottom of the tobacco chamber.

Referring to the bit l4, it is provided with a bore 2| of relatively small diameter projecting inwardly from which is a tube 22 forming an extension of the bore 2! and projecting towards the bowl end beyond an inner wall 23. The inner end of the bit is counterbored to provide a smoke cooling chamber 24 largely contained in the bit and into which protrudes axially the inner end of the tube 22. It is understood that the structure as thus far described is somewhat conventional and is illustrated herein to show the adaptability of the novel features of the disclosure to a known form of pipe.

The drawing discloses a metallic construction 25 fitted in the neck boreand comprising a thin walled sleeve 26 wide open at its outer end and provided with a wall 21 at the opposite end. A smalldiametered tube 28 extends through the wall 21, projects into and outlines, or at least partially outlines.the constricted portion IQ of the bore and leads to the bottom of the tobacco chamber H. The tube also projects to the right of the drawing a material distance beyond the wall 21 into the oil trap or condensing chamber 29 outlined by the sleeve 26.

The open end of the sleeve is closed by means of aplug like partition ,30 of a readily removable unit 3|, preferably formed of aluminum or :Bake lite. The partition 30 forms the right end of the condensing chamber 29 and the left end closure of the smoke cooling chamber 24. The unit 3| includes a long tube 32 projecting integrally from the partition 30 and. extending therefrom a material distance into the cooling chamber in axial alignment with and spaced slightly from the tube 22 carried by the bit. This long tube is designed to constitute a pouring nozzle or drain for discharging the condensing chamber of its oil or other fluid content when the bit is removed from the balance of the stem for this purpose. The tube 32 is of suflicient length to extend a material distance into the cooling chamher and thus provide an annular saliva drip receptacle 33, particularly designed for wet smokers. The long tube provides a finger piece or handle by means of which the unit as a whole may be withdrawn from the sleeve and for the purpose of facilitating the finger engagement the outer end of the tube is provided with a bulbular enlargement 34 to prevent the finger slipping off i the end of the tube.

The side of the partition 30 facing the condensing chamber is provided with a conical funnellike surface 35 designed to receive drip which may hug the inner wall of the sleeve 26 and discharge the same through the bore 36 of the pouring nozzle 32. The bore 36 should have a conducting capacity not only sufficient to convey the smoke therethrough in the normal operation of the pipe but should also have capacity sufficient to permit the flowing therethrough of the heavy liquid parts of the tobacco condensate. It is not intended in this structure that the heavy tars which settle in the condensing chamber be poured therefrom through the bore 36. These tars are best removed from time to time by withdrawing the unit from the sleeve and cleaning its inner surface with some rugged form of cleaning device or pipe cleaner. However, the lighter liquids can be more frequently discharged from the condensing chamber simply by removing the bit l4 which thus exposes the pouring nozzle and by merely tipping the shank or stem of the pipe downward the more flowable portions of the condensates may be quickly ejected; the bit restored in place and thus the pipe is cleaned to this extent and ready for renewed operation.

The metal parts and preferably the chamber lining shell 26 are preferably made of an aluminum alloy which functions to quickly dissipate heat from the bowl end of the stem. Oils and tars taken out of the smoke in the condensing chamber are prevented from entering thebowl and wetting the tobacco; therefore the tobacco may be smoked to the bottom of the bowl with nothing left but ash. However, the construction is designed so that if the smoker drools saliva while smoking it will be trapped in the chamber 33 at the lower end of the smoke cooling chamber in the event that the smoker habitually smokes with the bowl downward at a lower level than the bit or into the right end of the cooling chamber about the area into which the tube 22 protrudes in the event that the smoker habitually smokes with the bowl elevated.

While there have been shown, described and pointed out in the annexed claims, certain novel features of the invention, it will be understood that various omissions, substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention.
