Application November Z4, 1948, Serial No. 61,757

(Cl. ISI-202) 2 Claims.

This invention relates to smoking pipes and has for its ygeneral object the provision of simple and inexpensive means whereby the pipe may conveniently be cleaned and the products of com bustion, commonly known as sludge, nicotine, tar, etc., may readily be removed, and also the provision of means whereby such combustion products may be removed from the tobacco fumes before such fumes enter the pipe stem.

In the drawings accompanying and forming a part of this application,

Figure 1 is a central longitudinal section of a pipe embodying my invention.

Fig. 2 is a similar section of a modification.

Fig. 3 is an elevation on an enlarged scale of the cup hereinafter referred to.

Fig. 4 is a central longitudinal section of the condensation chamber and a portion of the tubular member affording a duct between the bowl and mouthpiece of the pipe.

Fig. 5 is a section on a still larger scale of the iilter provided for the inner end of the condenser chamber.

Fig. 6 is an end View on the same scale as Fig. 5 of said lter.

In the particular drawings selected for more fully disclosing my invention and the underlying principle thereof, said drawings to be considered as illustrative, merely, and not restrictive, I represents the bowl portion of the pipe which consists of three sections, namely, the bowl section II; the socket section I2 at the lowermost end of the bowl portion and the section I3 intermediate the other two. Secured into the intermediate section in any suitable manner by screw threads I4, as shown, or frictionally, is a tubular member I having an outwardly fiaring upper portion I6, the lower end of said tubular member extending into the socket section aforesaid.

A cup I 'I is disposed in the socket section I2 and held in operative position by any suitable means, such as the bolt I8, shown in the present instance, the inner end of said bolt being engaged in the peripheral groove I9 formed in the cup. The compression spring 20 forces the end of the bolt in the groove and by means of the button or finger piece I8' the bolt may be moved axially to release the cup. Interposed between the cup and the intermediate section of the pipe portion is a compression spring 2| so disposed as to urge the cup outwardly when the bolt is moved to the right. The cup may be lined with a sheet of absorbent material 22 which may readily be removed when the cup is sprung out of its socket and replaced by a clean sheet.

The stem portion 23 integral with said bowl portion, is provided with the usual duct 24 be tween the bowl proper and the mouthpiece 25.

After the pipe has been used for a whileI the cup is sprung out of its socket, as above de scribed, cleaned and replaced, but the spring 2l is so arranged that it will remain in the socket section I2 after the cup has been removed therefrom. In the present instance, the uppermost spire 26 of the spring is of greater diameter than the others and extends over the flaring edges of the cup, thus being in frictional engagement with the wall of the socket section I2.

As shown in Fig. 2, a tubular member 21 is disposed in the stem portion in register with the central longitudinal bore of the mouthpiece. The inner end of said tubular member which may be of aluminum, or other suitable metal, is enlarged both radially and axially to provide an expansion chamber 28, the function of which is to cool the smoke before it enters the mouthpiece and the inner end of said chamber is provided with filter means 29 of any suitable type. The lter means is frictionally engaged with the end of the expansion chamber and, as shown in Figs. 4 and 5, the periphery of the filter may be grooved, as indicated at 30, to receive a peripheral rib 3| formed on the inner surface of the outer end of the expansion chamber.

In the manufacture of the pipe, the bore 32 in which the bolt is disposed, is made by boring from the forward end of the bowl portion and that portion of such bore to the left of the socket section is then filled with a plug 33.

In the form shown in Figure 2, the stem portion is bored from end to end to form the duct 34 and then said duct is reamed out or otherwise enlarged suiiciently to accommodate the expansion chamber 28. The tubular member 21 may either be integral with the enlargement thereof which forms the condensation chamber or else rigidly attached thereto by electric welding or otherwise. The rearward end of said tubular member abuts the forward end of the mouthpiece and, as the enlarged end thereof snugly lits the bore in which it is disposed. the member 21 will remain fixedly in the position shown in Fig. 2.

Having thus described illustrative embodiments of my invention without, however, limiting the same thereto, what I claim and desire to secure by Letters Patent is:

1. A smoking pipe comprising in combination, a bowl, a mouthpiece, a stem portion provided with a duct between said bowl and mouthpiece,

a removable upwardly-extending open-ended cup disposed beneath said bowl, said bowl having a bore communicating with said cup and the outer periphery of said cup being provided with a groove, a spiral compression spring interposed between said bowl and saidV cup, said spring urging said cup outwardly, a spring pressed bolt having its outer end in engagement with said groove for locking said cup in operative position against the action of said compression spring and manually actuated means for moving said bolt axially to release said cup.

2. A smoking pipe comprising in combination, a bowl section, a socket section at the lowermcst end'thereof, a mouthpiece, a stem portion provided with a duct between said bowl section and mouthpiece, a removable cup disposed in said socket'section, said bowl section having a bore communicating with said cup, a compression spring interposed between said bowl section and said cup, said spring urging said cup outwardly, the uppermost spire of said spring being of greater diameter than the othersy and being disposed for frictional engagement with the wall of said socket section whereby said spring will remain in said socket section after the cup has been removed therefrom, and manually actuated means for locking said cup in operative position Vagainst the action of said spring. Y

FREDERICK MYERS.
