TOBACCO-PIPE.

SPECIFICATION forming part of Letters Patent No. 609,641, dated August 23, 1898.

Application filed November 80, 1897- Serial No. 660,205. (No model.)

To all whom it may concern.-

Be it known that we, SAMUEL D. WEBB and ISAAC L. JOHNSON, citizens of the United States, residing at Washington, District of Columbia, have invented certain new and useful Improvements in Tobacco-Pipes; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to to which it appertains to make and use the same.

The invention relates to improvements in tobacco-pipes whereby they can be easily and thoroughly cleaned at any time.

I 5 The invention consists in certain novel features hereinafter described andclaimed.

In the accompanying drawings, Figure 1 is a perspective view of the pipe complete. Fig. 2 is a perspective View of the two parts of the divided stem separated. Fig. 3 is'a sectional view showing the purifying-plug in position.

The main stem A, bowl B, and mouthpiece C may be of any desired material and ofany ornamental configuration, the stem being divided horizontally, as shown at a.

The lower portion a of the divided stem is provided on each side with a tongue 04, extending from end to end to the angle of the elbow a and thence from said angle upward to the point where the bowl joins onto said stem, the latter extension of said tongue being inclined upward and outward from the base, so that when the parts of the stem a and a are brought together they are firmly held and wedged together, forming a tight and firm connection between said parts, thereby preventing the two parts of said stem from separating laterally or being affected by heat 0 or moisture when the pipe is in use.

The stem is provided about centrally of its length with an enlarged opening or recess 1), in which may be inserted asmall cylindrical piece of charcoal, which acts to purify the 5 smoke and. take up or absorb all nicotine before the smoke passes to the mouthpiece, and as a consequence not only preventing the smoke from biting the tongue, but preventing injurious effect to the smoker.

The stem is preferably formed of hard rub 5o ber, as by the use of this material the same may be readily molded and vulcanized at a slight cost, the material being especially adapted to the purpose, as the stem does not become hot enough below the bowl either to soften the material or give out an unpleasant odor.

The elbow portion a is preferably provided with a male screw-thread N, as also the end of the stem 1) to which the mouthpiece is connected,and the lower end of the bowl, as shown at b, and the inner end of the mouthpiece, as shown at 12 are provided with a female screwthread to engage the same and act to hold the divided stem tightly and securely together and each part to the other.

By the use of the tongue and groove in the stem, with the tongue extending above the line of the opening for the passage of the smoke, it will be readily seen that they not only serve to render the parts more rigid and firmly lock the same in place, but that no nicotine can rise and escape under any circumstances between the walls of the tongue and groove and to the outside of the pipe.

The purifier is preferably made in conical or similar form and of charcoal and may be made into sticks of suitable diameter and then burned and out up into suitable lengths, so that a new one can be readily substituted as one becomes saturated with the nicotine.

When it is desired to wipe out the stem, it will be seen that all that is necessary to do is to remove the bowl and mouthpiece, disconnect the two parts of the stem, wipe clean with a paper or rag, and then replace the parts, all being accomplished more readily and in a more cleanly manner than is possible with pipes of ordinary construction.

Having now described the invention, what 0 is claimed as new, and sought to be secured by Letters Patent, is-

, In a pipe, a stem having a longitudinal portion and an integral portion projecting vertically from the forward end of the longitudinal portion, the stem being centrally divided into an upper and a lower member, tongues formed on the lower member, and grooves formed in the upper member into which the In testimony whereof We aflix our signatongues are adapted to snugly fit in assemtures in presence of two witnesses,

bling the stem, the tongues on the Vertical SAMUEL D. WEBB. portion of the stem being inclined from a Ver- ISAAC L. JOHNSON. tical direction, whereby when the members Witnesses:

are assembled, the inclined tongues will have ALEX. MAHON,

a Wedging action in their respective grooves. S. A. TERRY.
