TOBACCO PIPE 'Filed Dec. '22, 1939 Patented Jan. 13, 1942 'UNITED STATES PATENT POF-FICE TOBACCO PIPE Harold G.,Wyse, Dayton, Ohio Application December 22, 1939, Serial No. 310,482

structural features and inherent meritorious 3 Claims.

l This invention pertains to tobacco pipes and more particularly to a cooling and condensing unit interposed in the pipe stem.

The desire of every pipe connoisseur is for a dry, cool, sweet smoke. In the use of an ordinary tobacco pipe the smoke vapors and other products of combustion reach the mouth of the smoker in a more or less heated condition, accompanied by moisture extracted from the tobacco intermixed with saliva previously deposited in the pipe stem and frequently distastefully flavored by nicotine extract and tar compounds freed from the tobacco charge by combustion.

In the presentinstance, the products of combustion are conducted through a tortuous passage of sufficient length to effect radiation of the heat and condensation of entrained moisture and extractives, which are collected and segregated before reaching the pipe bit in the mouth of the smoker. As a result,` the smoke drawn from the mouth piece, or bit, is comparatively cool and uniformly dry, with no objectionable avor.

A primary object of the invention is to provide a radiator condenser pipe which may not only be economically manufactured, but will be more efficient in use, uniform in its operation, having relatively few parts and unlikely to get out of repair.

A further object of the invention is to provide a pipe of the character described of conventional shape and compact construction capable of being easily and quickly assembled and disassembled for cleaning.

A further object of the invention is to eliminate the strong soggy heel which forms in the bottom of the bowl of a conventional pipe, thus enabling complete combustion of the charge and minimizing tobacco waste.

A further object of the invention is to provide a smokeA from which objectionable extractives` have been eliminated and hence free from tongue bite.

A further object of the invention is to provide rapid and efficient heat transfer from the pipe parts to atmosphere by combined conduction, radiation, and convection.

A further object of the invention is to enable the trapping of all tobacco particles and moisture.

A further object is to provide a pipe structure wherein the radiator condenser unit is readily accessible and may be quickly disassembled for cleaning and thereafter reassembled.

A further object of the invention is to provide a smoking pipe having the advantageous characteristics hereinafter described.

With' the above primary and other incidental objects inview as will more fully appear in the speciiication,` 'the invention intended to be protected by Letters Patent consists of the features of construction, the partsv and combinations thereof, and the mode of operation, or their equivalents, as hereinafter described or illustrated in the accompanying drawing.

Fig. 5 is a cross sectional view on the line 5-5 of Fig. 2.

Fig. 6 is a side elevation of a cigarette holder in which the invention is embodied.

Like `parts are indicated by similar characters of reference throughout the several views.

In the accompanying drawing there is shown a pipe of conventional shape, including the bowl I, stem 2, and bit 3; The stem 2 includes a medially perforate tubular section 4 interconnected with the bowl I by an 'interposed fin carrying coupling 5.

VThe iin carrying coupling 5 has thrust engagement in the bottom of the bowl I and at its opposite end in the imperforate extremity 4a of the perforate section 4 and has therethrough` abore 6 connecting the interior of the bowl I with the imperforate extremity of the section 4. The perforate section 4 and iin carrying coupling 5 are preferably, formed of metal. Because of its high heat conductive characteristics, aluminum is the preferred but not necessarily the only suitable material.

Located within the perforate section 4 is a radiator and condenser unit comprising three thin walled condenser tubes l, 8, and 9, and end or terminal plugs I0 and II. The end plugs I0 and I I are each recessed to provide moisture collecting chambers I2 and I3. The raditator conalthough not necessarily,`

denser unit is of less length than the perforate tubular section 4, affording within the imperforate terminals 4a thereof intermediate the plugs I and Il, and coupling 5, and the bit 3 respectively, supplemental collecting chambers I4 and The tube I connects the initial collecting chamber I4 beyond the plug or head I0, to which smoke is admitted from the bowl, with the second collecting chamber I3 in the opposite plug or head I I. Tube 8 is relatively short and interconnects chambers I3 and I2, in the respective plugs I0 and II. Tube 9 connects chamber I2 in the plug I0 with the supplemental chamber I5 beyond plug II for discharge of cooled smoke to the bit 3. The perforate section 4 is counter-bored to provide a shoulder stop I6, against which the end plug I I abuts to insure proper positioning of the condenser unit within the perforate tube 4 to provide the supplemental chambers I4 and I5.

The radiator condenser unit is so constructed that it may be easily disassembled for cleaning. The tubes 'I and 9 extend through the chambers I2 and I3 and terminate iiush with the outer surfaces of the end plugs I0 and II, respectively. Tube 8 is located at the top of the unit, as shown in Figs. 4 and 5, and is -accessible for cleaning from either chamber I2 or I3.

The smoke passes through a tortuous path of travel in reverse directions and through a succession of spaced condensation and particle deposit chambers, in such path of travel. 'Ihe smoke drawn through the bore 6 of the coupling 5 passes into chamber I4 where all the tobacco particles drawn from the bowl I and the initial condensation of moisture are trapped. 'I'he smoke then passes through tube 'I into chamber I 3, where the moisture condensed during the passage through l the tube is trapped. The direction of ow is then reversed and the smoke passes through tube 8 to chamber I2 where further moisture condensation is trapped. The smoke again flows in the opposite direction through tube 9 to the chamber I5 where the final condensate is trapped, and from where the dry, cool smoke is drawn through the bit 3. The chamber I3 also serves to trap any saliva that may enter the pipe, or if not removed in this chamber, it will be collected and held by the succeeding chambers. Any moisture within the pipe stem is prevented from entering the bowl of the pipe thus the tobacco in the bottom oi the bowl is always dry and sweet and may be smoked to the very bottom with no harsh or irritating effects.

The heat generated by the burning tobacco and carried through the pipe stem by the smoke is dissipated in three ways, namely, by conduction,

by radiation, and by convection. The coupling 5 rapidly and efliciently conducts the heat of combustion from the bowl I directly to the perforate tubular section 4. Heat is dissipated to the atmosphere by direct radiation from both the tube and the coupling fin. The end plugs ID and 6 The tubular section 4 in addition to its heat transfer function serves as a guard or protective housing for the radiator condenser unit, preventing damage to the tubes, and preserving the conventional lines or shape of the pipe. In conjunction with the coupling 5 and bit 3 it defines the deposite chambers I4 and I5. The perforate tubular section 4 therefore serves a multi-functional purpose.

While the invention has b'een described in its application to a pipe, it is to be understood that it is equally applicable to a cigarette holder, as is shown in Fig. 6. Such construction is identical with that previously described with the exception that the cigarette receptacle Ia, the equivalent of the bowl I, is disposed in axially aligned relation instead of being disposed in right angle relation. It is therefore to be understood that the term pipe as herein employed is to be deemed generically inclusive of the cigarette holder embodiment, and that the terminal receptacle Ia of Fig. 6 responds to the term bowl as 'employed in the claims.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advant-ages.

While in order to comply with the statute, the invention has been described in language more or less specic as to structural features, it is to be understood that the invention is not limited to the specic features shown, but that the means and construction herein disclosed comprise the preferred form of several modes of putting the invention intol effect, and the invention is therefore claimed in any of its forms or modifications within the legitimate and valid scope of the appended claims.
