SMOKING-PIPE.

Specification of Letters Patent.

Patented Dec. 6, 1910.

To all whom it may concern:

Be it known that I, GEORGE WILDER CLAPP, a citizen of the United States, and a resident of the borough of Manhattan, in the county and State of New York, have invented an Improved Smoking-Pipe, of which the following is a specification.

This invention relates to improvements in smoking pipes and particularly to that class of pipes having a single smoke chamber communicating with the bowl and the mouthpiece.

In the preferred form of my invention shown, I provide the pipe with a self c011- tained cleaning device comprising a rod having an enlarged portion at its inner end adapted to cleanthe passage connecting the smoke chamber with the bowl or to clean the smoke chamber itself. This cleaning device may be permanently or detachably connected with the mouthpiece. In the form illustrated, I also provide an improved shape of opening at point of junction of smoke passage and tobacco bowl which said opening shall be rendered difficult to clog by the presence of the cleaning device. In the form shown, I also provide an improved metallic joint or connection between the mouthpiece and the stem of the pipe.

In the accompanying drawings which show different forms of my invention: Figure 1, is a side view of a pipe, partly in section and partly in elevation showing one form of my invention. Figs. 2, 3, 4iand 5 are sectional views of Fig. 1, on the lines 22, 33, 44 and 55 respectively. Fig. 6 is a view, similar to Fig. 1, showing another form of my invention. Fig. 7, is a similar view showing another form of my invention, the bowl and part of the stem of the pipe being removed. Figs. 8 and 9 are views partly in section showing difierent ways of connecting the cleaning device to the mouthpiece. Fig. 10 is a View of the cleaning device adapted to be sold independently of the mouthpiece or other part of the pipe. Fig. 11 shows the cleaning device applied to a pipe with a curved stem and smoke chamber. Fig. 12 illustrates in sectional View the various steps in forming the male and female members of my improved metallic joint.

In all figures where the bowl of the pipe is shown it is indicated by A, and the tobacco chamber by a. The bowl may be of any desired shape or size.

B indicates the stem of the pipe and C the mouthpiece. The stem may be of any desired shape cross-sectionally and extend from the bowl either at a right angle as in Figs. 1 and 2, at an acute angle as in Fig. 10 or in a curve as in Fig. 11. In Fig. l the stem is polygonal in cross section, while in Figs. 6 and 7, 10 and 11 it is supposed to be circular. The stem B is provided with a smoke chamber 5 which communicates with the lower end of the tobacco chamber a. In Figs. 1, 6 and 10 the communication is by way of a passage cl of less diameter than the smoke chamber, whereas in Fig. 11 the smoke chamber 6 in the stem is continuous and of the same diameter from the tobacco chamber a to the inner end of the mouthpiece C.

The cleaner as shown comprises a rod E having an enlargement or head 6 at its free end. The other end of the rod is connected either permanently or detachably to the inner end of the mouthpiece. By permanently I mean they are so connected that they cannot be separated without rupturing some part.

In Figs. 6 and 7 the cleaner is permanently connected to the mouthpiece as follows: An eye 7 is formed by the end portion of the rod E and lies at a right angle to the rod. This eye is clamped against the end of the mouthpiece by a metal cap 0 which fits over a reduced end portion of the mouthpiece and is secured in place thereon preferably by making small indentations g in the cap thereby forcing metal into the mouthpiece. The end of the cap which engages the eye is provided with an opening which connects with the bore of the mouthpiece.

In Fig. 8 the eye f is held in the bent flange h of a tube H which fits in a portion of the bore of the mouthpiece and is permanently secured therein by means of points i forced into the mouthpiece by indenting the tube. Obviously the tube might be formed -with the projections and the mouthpiece be molded on it.

In Fig. 9 the rod E is secured to the tube H in the same manner as in Fig. 8, but in this case there is a threaded connection between the tube H and the mouthpiece as 111- dicated by 70. This forms a detachable connection between the cleaner and mouthpiece.

Other means may be employed for connecting the cleaner and mouthpiece either permanently or detachably, those described being merely illustrative of how either form of connection may be made. For example, the cleaner might be soldered to the cap 0 or tube H.

As before stated the cleaner as shown comprises a rod with a head at its free end. r-Xs shown the head is conical in form and its base forms the extremity of the cleaner. The surface of the base may be fiat as shown in all the figures where it appears except in Fig. 9 where it is shown as being concave. The diameter of the base should be such as to cause a sliding fit between it and the passage (Z in Figs. 1, 6 and 10, or between it and the passage or smoke chamber Z) in Fig. 11. The shape or conformation of the head of the cleaner described presses any obstruction of the passage, together with the tobacco contiguous to the draft hole, back into the bowl and away from the edge of the same, so as to permit a free draft, and such shape or conformation of the head also permits the easy withdrawal of said cleaner through the said draft hole without drawing tobacco from the bowl with it. In all cases, except in Fig. 11, the rod E leads from the mouthpiece at one side of its bore and in order to bring the rod E centrally of the stem it is bent as indicated at Z. From the bend Z it may extend straight to the head 6 as shown in Figs. 6, 7 and 8, or may have a spiral twist m as in Figs. 1, 41-, 9 and 10.

When the pipe is in condition for use the largest section of the head 0 is contained in the tobacco chamber a and a portion of the rod E may also project into the tobacco chamber a and if the rod has the spiral twist m such twist will lie in thepassage (Z and be in contact with the surface thereof. The advantages of the spiral twist are that it supports the rod E centrally of the smoke chamber and lessens the liability of bending the rod when loading the pipe with tobacco. It also serves to diffuse the heat from the rod E to the stem and bowl and thus keep the mouthpiece cooler.

It will be observed that the head of the cleaner will act as an obstruction to the passage of tobacco to the lower portion of the passage d and thus prevent such passage from being clogged with tobacco, even if the latter should stop the passage above the cleaner. 7

When the passage (Z (or the smoke chamber b Fig. 11) becomes clogged, the mouthpiece is detached from the stem and the cleaner moved back and forth through the passage and the obstructing matter will be drawn out into the smoke chamber or forced into the bowl whence it can easlly be removed.

In Fig. 10, I have illustrated a cleaner that may be sold separately and applied to a pipe. In this case the cleaner is connected to a conical cup 8 adapted to fit in a tapered bore in the stem of the pipe and to receive the tapered end of the mouthpiece. If desired other conical cups a may be interposed between the mouthpiece and the cup .9, some of which may be metal or metal covered and others rubber or similar material in order that the mouthpiece may be inserted in either a metal cap or a rubber cap or other similar material.

With pipes of this character it is desirable to have a substantially air tight joint or connection between the mouthpiece and the stem. In the drawings I have shown different ways of connecting them together. Thus in Fig. 11 the end of the mouthpiece .is tapered and fits in a tapered hole in the stem, the material of which the mouthpiece is made and the wooden stem being in direct contact. In Figs. 6 and 7 the end of the mouthpiece is covered by a metal cap which contacts with the wooden stem. Either of these joints or connections is in the main satisfactory but I have found that the most easily operated, satisfactory joint or connection is when both the male and female members are metal. The tendency of both mem bers of the joint to aid in dispersing heat which might otherwise cause injury to the parts makes this formof joint particularly desirable where heat is brought to the joint through attachment of a cleaner. Such a joint is shown in Fig. 1, where the stem B is provided with a metal collar or ferrule 0 which projects beyond the stem, and the end of the mouthpiece is covered with a metal cap 0 which fits in the collar 0. The collar or ferrule 0 will be hereinafter referred to as the female member and the cap as the male member.

It is somewhat difiicult to make an air tight metal. joint of the character above referred to out of ordinary sheet metal owing to slight inequalities in the thickness of the sheet metal and also when entirely different sets of dies are used to make the two mem bers there will be inequality in the wear of the dies. A part of my present invention consists in a new method of making the two members which result in an air tight 21 with surrounding flange. 22. The cup is then preferably forced into a similar but smaller die although this is not essential. The flanged cup is then placed in a guide located over another die the opening in which is of less area than that of the guide whereby a shoulder is formed and a reduced opening below the shoulder. The bottom of the cup rests upon the shoulder and a punch having the same cross-sectional form as the opening in the die and having a sliding fit therein, is used to punch out the greater portion of the bottom thereby leaving the cup with an interior flange 23 around its lower edge. The cup is next forced through another die by means of a suitable punch to remove the flange 22 and thus complete the female member.

The blank from which the male member is made is indicated by 24 and it is first formed into a cup with a surrounding flange 25. The next step is to punch out a suitably shaped opening 26 in the bottom to form a smoke passage to the mouthpiece and also for the reception of the rod, E. The cup is then placed in the same die used to punch out the bottom of the female member from which the guide is removed, and with the same punch to which a leader is attached, the male member is forced through the reduced opening and the die will in conjunction with the leader and the punch scrape the wall and remove the flange 25, and the male member will then be completed. I have indicated in section a die and punch which may be used to operate on both members as described in which to is the guide, 00 the punch, 3 the shoulder and a the reduced opening or die in which the punch has a sliding fit. By this method of forming the two members the male member must of necessity have a tight driving fit with the internal flange 23 of the female member.

With a metal joint of this character when the parts are assembled the mail and female members are in contact only at the flange 23 and consequently the mouthpiece could rock slightly on the stem at the joint. This rocking will however be prevented by the engagement of the spiral twist m with the wall of the passage (Z.

Having described my invention, I claim 1. The combination with a pipe, of a mouthpiece, a passage connecting said n1outhpiece and the bowl of the pipe, a metal collar attached to the outer end of the stem and projecting beyond it, said collar having an internal flange at its outer end, a mouthpiece having a metal cap on its inner end to be inserted into the collar and form a substantially air tight joint with said internal flange, and a cleaner connected to the mouthpiece and extending into the bowl and having a bearing against the wall of said passage.

2. The combination with a pipe of a mouthpiece, a direct passage connecting said mouthpiece with the bowl of the pipe, a cleaner secured to the inner end of said mouthpiece and projecting through said passage into the bowl, the free end of the cleaner being adapted upon insertion to clear the passage and also press back the tobacco in the bowl contiguous to the bowl opening and being of such conformation as to permit easy withdrawal from the bowl.

3. The combination with a pipe of a mouthpiece, a direct passage connecting said mouthpiece to the bowl of the pipe, a. cleaner secured to said mouthpiece at its inner end and projecting through said passage into the bowl of the pipe, said cleaner having a conical head on its free end, the base of the cone forming the end of the cleaner and the sides inclining to the shank thereof.

4:- The combination with a pipe, of a mouthpiece, a passage connecting said mouthpiece and the bowl of the pipe, a metal collar attached to the outer edge of the stem and projecting beyond it, said collar having an internal flange at its outer end, the mouthpiece having a metal ca on its inner end to be inserted into the col ar and form a substantially air-tight joint with said internal flange.

In witness whereof, I have signed my name to the foregoing specification in the presence of two subscribing witnesses.
