sites PAT 4 Claims.

My invention relates to the class of devices which are commonly employed to contain tobacco in the act of smoking, and an object of my invention, among others, is to provide a pipe of this type which shall reduce to a minimum degree transference of heat and of nicotine material from the bowl to the mouthpiece.

One form of a pipe embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawing in which Figure 1 is a side view of my improved pipe.

Figure 2 is a similar view with the stem and mouthpiece partially broken away in central lengthwise section to show the construction.

Figure 3 is a side view of the parts making up the stem and mouthpiece, such parts being disconnected.

In the accompanying drawing the numeral 5 denotes the bowl of my improved pipe which may be composed of any suitable material common to devices of this kind and 6 denotes the mouthpiece which may also be composed of any desired material.

A union 1 is secured to the stem 8 projecting ba-ckwardly from the bowl, this union being also composed of any suitable material; It is recessed at one end to receive a stub 9 projecting from the mouthpiece 6, and a cup-shaped washer In may be located between the meeting ends of the union and mouthpiece, as shown in Fig. 2 of the drawing. The union 1 has also a stub II which projects into a hole in the stem 8, there being a cup-shaped Washer I2 of any suitable material enveloping the stub and the end thereof except for a hole through the bottom of said cup-shaped washer I2.

A collecting sleeve I3 extends into the union I and projects beyond the end of the stub I I, this sleeve having a port or ports it through the side thereof at a short distance from the end but within that part projecting from the stub II.

A nicotine collector I5 extends within and preferably through the sleeve l3, as shown in Fig. 2 of the drawing, this collector having a head I6 at its inner end and the body being tapered from said head to the opposite end thereof.

In operation a draft being created through the openings in the stem, union, and mouthpiece, as by suction at the end of the mouthpiece, smoke will be drawn through the port or ports I4 and through the sleeve I3 and this will lessen the amount of heat which will be conveyed to the mouthpiece 6. Nicotine and similar objection able substances extracted from the tobacco in the smoking operation will also pass into the ports I4 and will be collected within the sleeve I3, as well as upon the stem of the collector I5 and the head it, thus preventing the passage of such substances to a minimum degree to the mouthpiece 6.

The sleeve and collector may be readily removed for cleaning purposes and when so re moved matter collected therein and thereon may be easily cleaned off, thereby rendering the pipe capable of very sanitary conditions.

1. A pipe including a bowl with a stem extending therefrom having a chamber therein, a mouthpiece, a union connecting said stem and mouthpiece in spaced relation, a sleeve extending into said union and filling the hole therethrough and projecting from the inner end thereof and spaced from the entrance end of said chamber and having a port through the side wall of said projecting end, and a collector extending into said sleeve and loosely supported within and by said sleeve and of tapered shape as to that portion within the sleeve to provide a tapered space between the collector and sleeve constituting a smoke passage gradually increasing in area from said port to the outer end of said sleeve, said collector having a head on its projecting end to close the opening into the end of the sleeve and spaced from the inlet end of said chamber.

2. A pipe including a bowl with a stem extending therefrom and having a chamber therein communicating with a recess in the bowl, a mouthpiece, a union connecting said stem and mouthpiece in spaced relation, a sleeve extending through said union to fit and fill the hole therethrough and projecting into said chamber to an extent to leave a clear space between its end and the end of the chamber at its entrance to the recess in the bowl, and a collector located within said sleeve and of tapered shape to provide a passage gradually increasing in area for the flow of smoke throughout said passage.

3. A pipe including abowl with a stem extending therefrom and having a chamber therein, a mouthpiece, a union connecting said stem and mouthpiece in spaced relation, a sleeve extending through said union to fit and fill the hole therethrough and projecting into said chamber to an extent to leave a clear space between its end and the end of said chamber at its entrance to the bowl, and a headed collector extending through said sleeve with said headlocated in said chamber and spaced from the entrance in the latter into the recess the b w said collector bein of tapered shape to provide a passage gradually increasing in area from one end to the other of the passage within said sleeve for the flow of smoke throughout the length of said passage.

4. A pipe including a bowl having a stem extending therefrom and a chamber therein, a mouthpiece, aunion connecting said stem and;

mouthpiece in spaced relation, a sleeve extending through said union to fit and fill the hole therethrough and projecting into said chamber to an extent to leave a clear space between its end and and spaced from the recess in the bowl into said 7 chamber.
