TOBACCO-PIPE.

Specification of Letters Patent.

Patented April 7, 1908.

Application filed March 15, 1907. Serial No. 362,677.

Be it known that I, WILLIAM H. HOOKER, citizen of the United States, residing at Manchester, in the county of Hillsboro and State of New Hampshire, have invented certain new and useful Improvements in Tobacco- Pipes, of which the followin is aspecification.

he present invention is in the nature of an improved tobacco pi e embodying novel means for collecting t e moisture from the mouth and reventlng the same from entering the bow and also provided with means for preventing any ashes from reaching themouth of the smoker.

To this end the invention com rises a pipe, the bowl of which is formed wit a series of ash collecting chambers, while the stem is peculiarly designed to constitute a check valve for preventin from the mouth to t e bowl of the pipe and has the free end thereof received within a hollow mouth-piece.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for eifectingthe result, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a longitudinal sectional view throu h a pipe constructed in accordance with t e present invention. Fig. 2 is a similar view showing a modification.

Corresponding and like parts are referred to in the followin descriptlon and indicated in all the views 0 the drawings by the same reference characters.

The numeral 1 designates the main or outer bowl of the pipe, the lower ortion of which is provided with the lateral y extending neck 2 which serves as a means for connecting the check valve 3 and mouth piece 15. Fitting removably within the outer bowl 1 is an inner or supplemental bowl 20, the upper edgesof which are turned outwardly at 30 to form an annular shoulder normally enga ing the upper portion of the bowl 1. The bottom of the inner bowl 20 is spaced from the bottom of the main bowl 1 in order to form an ash collecting chamber 4 and is perforated as indicated at 5 to form openin s through which the smoke can be drawn. t will also be observed that the opening within the neck 2 is enlarged to form a second chamber 6 which may be utilized for filtering purposes and is separated from the before mentioned chamber 4 by means of the transverse partithe flow of moisture tion 7. An opening or passage 8 is formed in the upper portion of*the partition 7 and the said passage 8 communicates with a cutaway portion 9 in the interior of the bowl 1 and on one side of the supplemental bowl 20, thereby being the means of causing what may be termed an indirect draft. It might be mentioned that the passage 8 is preferably formed at such an angle as to be readily accessible from the neck 2.

intermediate portion of the check valve 3, and the forward end of the said check valve is threaded as indicated at 11 and is designed to be screwed into the neck 2 until the shoulder lO abuts thereagainst. The rear end of the longitudinal passa e 12 through the check valve 3 is closed as indicated at 13 and is in communicationwith a downwardly extending lateral opening 14.

itting over the outer end of the check valve3 1s a hollow mouthiece 15 which is designed to com letely inc ose the rear ortion of the chec valve and normally a uts against the shoulder 10 thereon. The opening within the mouth-piece 15 is enlarged as indicated at 16'to form a pocket for receiving the moisture from the mouth and preventing the same from passing throu h the check valve and entering the bowl. this connection it may be mentioned that the o ening through the mouth-piece is gradua y talpered from the enlar ed portion 16 throug the extremity thereol thereby forming inclined walls which normally tend to discharge any moisture toward the enlarged portion or pocket. When it is desired to remove the accumulatin moisture this result can be readily accompfished b slipping the mouth-piece from the check valve and g1vin it a quick longitudinal movement in a we own manner. It will thus be a parent that when the smoker draws inward y upon the mouth-piece the smoke must pass through the two chambers 4 and 6 and that owing to the indirect draft produced through the opening or passage 3 fine particles which might be held in suspension Wlll be de osited in the said chambers. If found desira le an approved form of filterin material as indicated at 19 may be placer? in the chamber 6.

17 is formed in the bottom of the chamber 4 so that a small amount of cold air is intermingled with the smoke before the same enters the mouth, thereby producing a cool An annular shoulder 10 is formed upon an i In the preferred construction a small air inlet is claimed as new is:

pleasant smoke. It will also be apparent that any .moisture which may enter the I mouth-piece 15 can not find access to the check valve 3 owin to the fact that the rear end thereof is closed, and that the said moisture will accumulate in the pocket 16 in such a manner that it can be readily removed when necessary.

A modification is shown in Fig. 2 in which the forward end of the check valve 3 fits tightly within the neck of the pipe while the rear end thereof is reduced to form the shoulder 18 against which the mouth-piece 15 which 'is of the usual construction abuts. This construction does away with the threaded connection between the check valve and the bowl and admits of the various members being quickly taken a art. It will also be apparent that with t 's I construction the c eck valve can be removed if desired and the mouth-piece 15 applied to the neck 2 in the usual manner.

Having thus described the invention, what 1. In a ipe, the combination of a bowl formed wit a neck 'ro'vided with a chamber, a sup lemental owl fitted within the main bow and spaced from the bottom thereof whereb a second chamber is formed .and having below the supp emental bowl, the chamber in the neck and the chamber below the supplemental bowl being separated by a partition having a communicating passa e at one side thereof, a check valve receive by the neck a longitudinal passage therethrough which is closed at the rear end ofthe check valve, and a hollow mouthiece fitting over,the rear portion of the chec valve and spaced therefrom to form a trap.

2. In a pipe, ,the combination of a bowl having an air inlet in the bottom thereof and formed with a neck provided with a chamber,

-a supplemental bowl fitted within the main bow and spaced from the bottom thereof wherebya second chamber is formed below the supplemental bowl, the chamber in the neck and the chamber below the supplemental bowl being separated by a partition having a communicating passage at one side thereof, a check valve received by the neck and having a longitudinal passage therethrough which is closed at the rear end of the check valve, and a hollow mouth-piece fitting over the rear portion of the check valve.

In testimony whereof I afiix my signature in presence of two witnesses. a WILLIAM H. HOOKER. [L. 3.]
