TOBACCO-PIPE.

Specification of Letters Patent.

Patented Feb. 10, 1914.

Application filed February 26, 1913. Serial No. 750,887.

to be a full, clear, and exact description of I the invention, such as will enable others skilled in the art to which it appertams to make and use the same.

This invention relates to tobacco-pipes, and

has for its object the provision of a simple and eflicient device for preventing the clogging up of the smoke channel by the entrance of bits of tobacco into it, or by the closing of the orifice at the bottom of the bowl leading into the stem, and at the same time to provide an entrance way for air across the entire bottom of the bowl.

Other objects are to provide for easily cleaning the bowl and to avoid recesses or pockets in which the nauseating liquids so annoying to a smoker may collect.

The invention will first be hereinafter more particularly described, with reference to the accompanying drawings, which form a part of this specification, and then pointed out in the claims at the end of the description. In said drawings I have shown my improvement applied to a pipe with a straight stem but it is applicable to any kind of pipe, straight, crooked, bull-dog, Hungarian or what-not.

Figure 1 of said drawings represents a longitudinal sectional view, taken through the center of a pipe, showing embodied therein the preferred form of my invention; Fig. 2 is a top plan view of the pipe shown in Fig. 1; Fig. 8 is a longitudinal sectional view taken through the center of a pipe showing embodied therein a modification of my invention, and Fig. 4 is a vertical sectional View taken on the line 4.-1 of Fig. 3.

Referring to said drawings, in which the same letters of reference are used to denote corresponding parts in different views, the letter A may denote the pipe bowl, B the stem and C the mouth-piece detachably secured to the stem B.

which is placed a coiled spring D, of sufli'.

As shown in Fig. 1, the smoke channel I).

retain .it in place when compressed and pushed down into the bowl until the ends thereof fit into the recesses a c at the opposite ends of the enlarged portion of the smoke channel.

As shown in Fig. 2, rect-ly under the bowl and in the stem only, and serves to prevent the clogging of the smoke channel or the closing of the orifice cient length to exert a pressure that will 1 the spring D lies dii at the bottom of the bowl leading into the stem, by preventing the entrance of bits of tobacco therein, and at the same time acts as a strainer and greatly facilitates the passage of air from the bowl into the stem. This simple contrivance also distributes the entrance way for air and smoke across the entire bot-tom of the bowl. The open core of the spring being in line and continuous with the bore of the stem and mouth-piece also adapts the pipe to be easily cleaned by inserting a pointed instrument or ordinary cleaner through the stem and into the bott m of the bowl.

In the modification shown in Fig. 3, the smoke channel extends to the rear of the bowl constituting in effect a continuation of the recess in the bottom of the bowl in alinement with said channel and the spring D is slightly smaller in diameter than the smoke channel, and somewhatlonger,being adapted to fit snugly therein, and is inserted by removing the mouth piece, which may be either of the style known as push stem or whichmay be fastened to the stem by means of athreaded stud c screwed into an interiorly screwthreaded socket in the stem. The spring is inserted through the smoke channel until oneend thereof rests in the recess a in the rear wall of the bowl, and the mouth-piece is then pushed or screwed on so as to compress the spring which is held in place and tensioned by the pushing or screwing into place of the mouth-piece in the stem.

The advantages of the described construction are obvious. A neat and desirable pipe is produced in which clogging of the stem is obviated, and when cleaning becomes neces sary, any ordinary pipecleaner may be inserted through the stem, or if a cleaner is not handy the point of a pen-knife may be inserted through the bowl, and the passage of air from the bowl into the stem is greatly facilitated, because of the good clean draft provided by the large surface of the spring exposed in the bottom of the bowl, and all hollows or crevices in which the noxious liquids and gases so common to most pipes can collect are eliminated.

It will be understood of course that other kinds of springs might be used inst-ad of the spiral form shown, and that other changes may be made in the construction and arrangement of parts without departing from the-spirit and scope of my invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1,. In combination with the bowl of a tobacco pipe, a coiled sprin seated. in the bottom of said bowl and having the opening through the coil arranged in alinement with the smoke channel through the pipe stem.

2. In a tobacco-pipe, the combination of a bowl having in its bottom a recess extending across the bowl in alinement with the smoke channel, and a spiral spring fitting in said recess with one end seated against the rear of the bowl and its other end extending into said smoke channel, its ends abutting oppositely disposed shoulders at opposite ends of said recess.

3. In a tobacco-pipe, the combination with a bowl, of a, stem provided with a smoke channel, a recess in the bottom of the bowl in alinement with said channel, and compressible spring fitted in said recess and extending entirely across the bottom of the bowl.

4.. In a tobacco-pipe, the combination with a bowl, of a stem and a mouth-piece adapted to be attached to said stem, a compressible spring arranged within the bowl in alinement with the smoke channel in said stem and extending entirely across said how], together with means for holding said spring in place.

5. The combination with a tobacco pipe having a bowl, a stem, and a detachable mouth-piece, of a compressible spring fitting in said stem and extending across the bot tom of the bowl; said spring having an open center forming a continuation of the smoke-channel in the mouth-piece, and means for confining said spring in position within the stem and bowl.

6. In a tobacco-pipe, the combination with a bowl, of a coiled spring fitting across the bottom of said bowl and held in place solely by its expansive force; the open center of the spring being in alinement with the smoke channel in the pipe stem.

In testimonv whereof I affix m 1 si nature I in the presence of two witnesses.
