TOBACCO-SMOKING PIPE.

SPECIFICATION forming part of Letters Patent No. 686,176, dated November 5, 1901.

Application filed April 19, 1901. Serial No. 56,549. (No model.)

To all whom it may concern:

Be it known that I, CLAYTON L. WILSON, a citizen of the United States of America, residing at Munhall, in the county of Allegheny and State of Pennsylvania, have invented certain n'ew and useful Improvements in Toba'cco-Smoking Pipes, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in smoking-pipes, and

has for its object the provision of means Y shaped nicotin-receptacle, on the side of whereby the nicotin, saliva, and other impurities are conveyed into a reeeptacle,which will prevent the pipe from becoming foul.

A further object of the present invention is to provide novel means that will eifectually prevent the pipe-stem and the connections between the pipe-stem and bowl from clogging and assuring at all times a perfect draft from the bowl to the mouthpiece of the pipe.

The invention still further aims to construct a pipe in such a manner that a cool smoke can be obtained at all times,which will prevent the burning of the tongue and retain the pipe-stem cool, preventing the same from cracking, which is usually caused by the expansion and contraction when the pipe becomes overheated.

A still further object of the invention is to construct a pipe of the above-described character which will be extremely simple in its construction, strong, durable, and comparatively inexpensive to manufacture, and, furthermore, one that will be highly eflicient in its use, and to arrange the parts in such a manner that the same may be easily cleaned.

\Vith the above and other objects in view the invention consists in the novel combination and arrangement of parts to be hereinafter more fully described, and specifically pointed out in the claims.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, and wherein like numerals of reference indicate corresponding parts throughout the several views, in which- Figure 1 is a vertical sectional view of a pipe provided with my improvements. Fig. 2 is a vertical sectional view of the nicotinreceptacle. Fig. 3 is a top plan view thereof.

Fig. 4: is a side elevation of a modified form of nicotin-receptacle. Fig. 5 is a vertical sectional view thereof. Fig. 6 is a longitudinal sectional View taken on the line 6 6 of Fig. 5, looking in the direction of the arrow. In the drawings the reference-numeral 1 indicates the bowl of the pipe, having a contracted passage 2 communicating therewith, said contracted passage 2 communicating with an elarged chamber 3, also formed in the body portion of the pipe.

The reference-numeral 4 represents a cone- Which is provided a channel 5,communicating with the enlarged chamber 3, this channel 5 extending upwardly approximately twothirds the length of the nicotin -receptacle 4 and is arranged on the interior side wall of said receptacle 4. This receptacle has interiorly-arranged screw-threads 6 at the upper extension or end of the same to receive the stem 7 of the pipe, said stem 7 having arranged therein the usual passage-way 8 and is provided at its lower end with an enlarged portion 9, forming an annular shoulder 10, this shoulder 10 being adapted to abut against the upper end of the nicotinreceptacle 4. The stem 7 has also formed integral therewith a downwardly-extending portion 11, which is slightly conical in shape to conform with the inner screw-threaded wall 6 of the nicotin-receptacle. This portion carries external screw-threads 12, registering with said screw-threads 6 of the nicotin-receptacle and serves to secure these two parts together. Extending downwardly and formed integral with the portions of the stem is a cone-shaped nipple 14:, arranged centrally on the under side of the downwardly-extending portion 11, said cone-shaped portion forming an annular shoulder 15,extending to the outer deflectingwalls of the cone-shaped nipple 14.

The reference-numeral 16 indicates a passage leading from the nicotin-chamber proper to the channel 5. This passage 16 may also be formed in the walls of the nicotin-receptacle, as shown in the modified form in Figs. 4 and 5 of the drawings.

The operation of my improved pipe is as follows: When the pipe is in use, the 'saliva that is allowed to enter the passage-way of the stem will be conveyed downwardly into the nicotin-chamber 4 and cannot again reenter the passage-way 8, as the distance between the bottom of the nicotin-chamber and the nipple is too great to allow of such action.

Furthermore, the fact that the bottom of the nicotin-chamber is closed a direct draft cannot be created that would aid such an action taking place, as is the case in the ordinary form of pipe. The nicotin that may be drawn up from the bowl of the pipe through the channel 5 will be conveyed through the passage 16 to the deflecting-walls of the coneshaped nipple 14 and will also cause the nicotin to be conveyed into the chamber with the saliva, as heretofore stated. The smoke will enter and is conveyed through channel 5 and thence downwardly to the mouth of the nipple 14 by reason of the deflecting-walls of the nipple and the annular shoulder 15. The smoke will then further seek its natural course throughthe passage-way 8 and the mouth of the same. By the arrangement as heretofore described a cool smoke is obtained at all times and many advantages are thereby obtained, as heretofore stated.

A still further advantage must be apparent when it is desired to clean the pipe, the stem 7 being removed from the nicotin-receptacle and the latter disengaged from the bowl of the pipe, when the contents of the nicotinchamber may be readily removed without soiling the fingers and the parts again assembled and placed in proper position for the refilling of the pipe.

Instead of constructing the channel 5 in the interior of the nicotin-chamber, as shown in Figs. 1, 2, and 3 of the drawings, I may form a semicircular channel on the outer face of the nicotin-receptacle and employ the inner wall of the bowl as the corresponding opposite wall of the channel. In this construction I provide an opening 16 in the wall of the receptacle to communicate with the nicotin-chamber, as shown in Fig. 5 of the drawings. This particular form of construction presents two further advantages, namely:

When manufacturing the nicotin-receptacle the channel 5 can be made without boring through the Wall, and, furthermore, when thus constructed on the outer face this channel may be more readily cleaned.

In view of the above statement I do not wish to limit myself to the particular construction as shown, as various changes may be made in the details of my improved pipe without departing from the general spirit of my invention. For example, the attachments may be easily applied to a straight-stemmed pipe as well as the particular form as illustrated in the drawings.

Having thus fully described my invention,

-what I claim as new, and desire to secure by Letters Patent, is-

1. In a smoking-pipe, the combination with the bowl, of a cone-shaped nicotin-receptacle frictionally held in the bowl and having a chamber, a channel formed in the .wall of said receptacle extending partially the length of the receptacle and communicating at one end with the nicotin-chamber and at the other end with the chamber in the bowl of the pipe, and a stem threaded into the outer end of the nicotin-receptaele,subs tantially as described.

2. In a smoking-pipe, the combination with the bowl, of a cone-shaped nicotin-receptacle, frictionally held in the bowl and having a chamber, a channel formed in the wall of said receptacle extending partially the length of thereceptacle and communicating at one end with the nicotin-chamber and at the other end with the chamber in the bowl of the pipe, and a stem threaded in the outer end of the nicotin-receptacle, said stem having a nipple which projects into the nicotin-chamber beyond the discharge end of the channel, substantially as described.

In testimony whereof I affix my signature in the presence of two witnesses.

CLAYTON L. WILSON.
