1 Claim. 1

This present invention relates to improvements in tobacco smoke pipes.

In the construction of such pipes difficulty has been encountered in keeping the smoke passage thereof throughly clean and free from contaminating influences of saliva, nicotine, and gummy matter formed by contact between the saliva, nicotine and partially ignited clots of tobacco, etc. The nuisance resulting from this drawback, at times, has interfered with making a pipe a pleasure.

It is the main object and purpose of the present invention to eliminate any tendency of the tobacco smoke pipe becoming clogged at any point along the length of the smoke passage thereof, for any reason whatsoever. This object is effected by providing, in the stem of the pipe, and along the bottom of the bowl thereof, a formation of parts and. an assembly of same that conveniently assures roomy accumulation of foreign matter without interfering with withdrawal of smoke through the smoke passage and mouthpiece of the pipe, and yet which permits instant removal from the pipe of all impediments which may originate from the contents of the bowl.

Oneof the objects of this invention is to provide a simple, easy and eificient method of cleaning the inside parts of a pipe with a view of interrupting the free and easy movement of objectionable or noxious matter along the smoke passage of the pipe, in the course of smoking the pipe, and enabling same to be discharged quickly from the pipe when it is not being smoked.

Another object thereof is to provide means in a pipe of the kind described, whereby a through smoke passage is formed, opening out of the pipe from end to end thereof, and communicating with the bottom of the bowl for the purpose of receiving, dislodging, and discharging foreign matter that is present in the pipe.

A further object thereof is to provide, in a pipe of the kind described, means for admitting air into the bowl and smoke passage of the pipe, in a regulatory manner.

Another object thereof is to provide, in a pipe of the kind described, means, manipulatable externally of the pipe, for thoroughly agitating noxious or foreign matter collectin therein, at any point, for the purpose of loosening same and ejecting it speedily.

With the above and other objects in view, my invention consists in the combination, arrangement and details of construction disclosed in the drawings and specifications, and then more particularly pointed out in the appended claim.

In the drawings, wherein similar reference characters designate similar parts throughout the respective views,-

Figure 1 is a longitudinal sectional view of my invention Figure 2 is a sectional detailed exaggerated view of the bowl end of the pipe, and

Figure 3 is a fragmental rear end elevation of my invention.

A cool smoke can be had from a tobacco smoke pipe only when conditions in the interior thereof permit a separation to be made of the path of flow of smoke through the smoke passage of the stem from the path of movement or accumulation of noxious matter, such as nicotine or the usual viscous, gummy matter ever present in pipes, and, where provision is also had for air-venting the smoke passage.

It is the primary purpose of this invention to accomplish this as shown in the drawings, which are merely illustrative thereof.

The elongated pipe stem of the pipe is designated I3, and the bowl is denoted at I I, the interior or chamber of the bowl being indicated at I2.

The stem I 3 has a tongue and grooved connection with the hollow shank III of the pipe, as shown in Figure 1, at I5a. I form a longitudinally extending straight smoke passage I6 from end to end of the pipe, which runs co-extensively with the length of the pipe. This smoke passage opens out of the mouthpiece I5 of the stem I3 of the pipe, at one end thereof, and also opens out of the outermost end of the pipe just to the rear of the bowl II.

I provide an elongated spirally fluted or twisted rod I! of a length substantially equal to that of the pipe, and I locate same in the passage I6, in such a way that some of its convolutions, or vanes I 9,,will project into the bottom I8 of the chamber I201 the bowl II where this chamber communicates with the passage l6.

The inner end of the spirally twisted rod I1 is flush with the open end of the mouthpiece I5 of the pipe, while its outer end is flush with the outer end of the passage I6. This passage I6 is formed immediately to the rear of the bowl II, with a portion of enlarged diameter forming a counterbore 2I, which communicates with that portion, 28 of passage I6, which recedes from the bottom I8 of the bowl chamber I2.

For the purpose of closing the exit of the passage I6 from its terminal 20, I provide a cylinldrical plug 22, formed with an integral enlarged cylindrical head 23.

The plug 22 is snugly received in the counterbore 2! of passage I6, but the head 23 thereof is located externally of the pipe, as is clearly indicated in Figure 2. The head 23 will abut the adjacent surface of the pipe when the plug is completely seated in the counterbore 2|.

The bowl chamber I2 has an air outlet to the atmosphere. For this purpose, bowl I I is formed with a port 25. The closure member 22-23 is also provided with an air venting passage consisting of the part 26 formed in the periphery of the 3 plug 22, and the part 21 formed in the head 23. As is best seen in Figure 3, the passage 2E2'| of the closure member may align with, or disalign with, the port 35, of the bowl H, according ,to the distance that the head 23 is rotated. Theperiphcry of the head 23 will be knurled as at 21.

With the foregoing construction, the use and operation of the pipe will now be described,

When smoking tobacco is placed in thechamber l2 of the pipe, some of the same will necessarily rest upon the vanes l9 of the spirally twisted rod I 1, because these vanes enter'the bottom of the bowl chamber at IS. The only way smoke can be drawn through the stem l3 of the pipe, into the mouthpiece l5 thereof, out of the bowl chamber :2, is in a necessarily spiral path around the vanes of the rod I6 extending the full length of the stem in the passage Hi. This slows up slightly the flow of the smoke, and interrupts its free and untrammeled movement out of the stem of the pipe.

There is a tendency of saliva from the mouth of the smoker entering the stem {3 of the pipe by way of the mouthpiece I5. There is also a tendency of nicotine and other noxious foreign matter finding its way out of the chamber l2 of the bowl H into the passage 6. The saliva may mix with the foreign matter, producing aviscous, gummy mass that adheres to the wall of the passage with a clogging activity. At times the bottom id of the chamber 42 ofthe bowl may itself become clogged, or hampered from passing smoke through the passage when a suction is established therein, due to the presence of the gummy mass, or for other reasons. All such impediments will prevent-the pipe from functioning properly, to'the discomfiture of the smoker.

The spirally twisted rod I? performs the oflice of obviating these handicaps to enjoyable smoking. It operates'to loosen, to agitate, spread out and scrape off foreign matter of any "kind that tends to cling to any surface except itself. This is eifected by shifting the spirally twisted rod longitudinally in and out of the counterbored end of the passage 16, and also by rotating the .rod as this is done.

There is no recourse for the particles of noxious foreign matter present in the pipe to directly or immediately move towards the mouthpiece end of the pipe once it gets into passage 16 and emerges from the bottom 18 of the chamber of the bowl ll. Such particles will encounter the adjacent vane or convolution of the spirally twisted rod H and cling thereto, and under influence of the suctionin the stem [3 and passage 16, such particles, before they have time to cling to the rod, may begin to move longitudinally of the rod. Itiis obvious, however, that this movement is a slow, retarded, interrupted one, dueto the long series of vanes onthe rod. Thiswill permit withdrawal of the smoke along the length of the rod, as is desired, out of the mouthpiece 15 thereof, without ejecting any of the foreign matter at the same time.

Should there be no-response by way .of outflow of smoke andair as a result of the suction created in the passage 16 by the smoker, it is apparent that an obstruction exists somewhere in the 'line oft-he passage 1 Giromend to end of the pipe. The smoker will then take hold of the knurled head 23 of the ;rod l1 and rotate the same violently soas to agitate whatever solid matter engages the rod at any point along its length in :the passage .lfi- Th m ef e th ee ius h passa 4 l6 and also stir up the tobacco burnt mass in the bottom of the chamber l2 of the bowl ll, so this mass is spread out to allow voids to exist for the passage of air.

If such rotation of the spirally twisted rod is not sufficient to accomplish the cleaning of the interior of the pipe, the smoker will then completely withdraw the rod out of the passage by taking hold of the head 23 thereof, and pulling the .rod bodily out of passage l6. He can then effectively and quickly clean whatever accumulations of foreign matter he finds clinging onto the vanes thereof. He then replaces the spirally twisted rod in the pipe.

The operator can reciprocate the rod in the passage [6 by partially pulling it out and pushing it in the same, and by rotating this rod while doing so he will, in most cases, loosen up accumulations of gummy material that clog up the passage IS.

A cool smoke is assured the smoker by reason of the fact that he can introduce at will, air into the passage I6 and bowl of the pipe. By turning head 23 of the rod properly, he can register the passage 2621 of the rod partial1y, or fully, with the port 25 of the bowl II. By moving this head 23 properly, he can place the passage 29 2l out of registration with the port 25. In this way no air will enter the bowl or passage l8 of the pipe. Since the smoke is filtered in making its traverse through the long series of vanes of the rod out of the stem l3 of the pipe, a cool, clean smoking is made possible at all times.

From the foregoing it will be seen that I have provided a simpler, easier and cleaner, as well as more sanitary, method of smoking a tobacco pipe than will be had if the spirally twisted rod were'not present with its air admission valve.

I do not intend to confine myself to the exact details of construction set forth, save as pointed out in the appended claim.

What I desire to secure by Letters Patent:

A smoking pipe comprising a bowl, a stern on said bowl, said stemhaving a longitudinal smoke passage therethrough intersecting said bowl at the bottom thereof and opening on the forward side of the bowl, said bowl having a counterbore concentric to said smoke passage, said bowl also having an air vent passage communicating with said counterbore and said bowl adjacent said smoke passage, a plug rotatable in said counterbore having a vent passage therein for registration with the air vent of said bowl, and a spiral member fixed on said plug disposed in said smoke passage along the length thereof whereby said plug may be rotated for displacing obstructions in-said smoke passage and positioning for controlling the air vent into said bowl.
