Patented Mar. 23, 1937 UNITED STATES PATENT OFFICE 9 Claims.

This invention relates to a pipe for smoking tobacco and more particularly to a pipe of the up-draft type.

An object of the invention is to provide a pipe of this character having superior smoking qualities which is simple and sturdy of construction, economical to manufacture, and both light of weight and pleasing to the eye.

Another object is to provide a pipe which is productive of a cool dry smoke and in which the most economically feasible consumption of tobacco is obtained.

A further object is to provide a pipe which is adapted to prevent any ashes or fire being dropped from it while it is being used. This particularly adapts it for use in the home and in the automobile where the type of pipe customarily used in the past has been the cause of considerable trouble and damage due to the 1 no ashes falling out of them, such for example as the damaging of the users clothes, starting of fires, wrecking of automobiles and sometimes even homes, although in the latter case not necessarily because of fires.

An additional and exceptionally desired feature of the invention is the provision of a. pipe having a totally enclosed bowl and one free of any distasteful smoking such as is customarily encountered in the common form of pipe when the fire reaches the bottom of the bowl.

These and various other objects as well as the various other novel features and advantages of the invention will be apparent when the .following detailed description is read in conjunction with the accompanying drawing of which Fig. l is a side view of a pipe made in accordance with the invention; Fig. 2 a sectional view of the same; Fig. 3 a view similar to Fig. 2 of a modification of the invention; Fig. 4 an exploded sec- 4o tional view of the bowl encasing shell; Fig. 5

a top view; Fig. 6 a detail sectional view of the snap connection between the two parts of the bowl encasing shell; Fig. '7 a plan view of the grid used for holding the tobacco in the bowl; and Fig. 8 a perspective view of a pellet of tobacco adapted for use in the modification of the invention shown in Fig. 3.

Referring in detail to the drawings according to this invention a pipe is provided which comprises an inverted bowl i having a duct 2 in it communicating with the inner end of the tobacco chamber 3 and in which a conventional stem 4 provided with the usual mouth-piece is secured by a suitable coupling 5.

For totally encasing such bowl so as to prevent any ashes or sparks falling from it a shell or housing is provided comprising an upper part 6 and a lower part 1 which may be made of any suitable materialv but shown here as being made of metal. As illustrated the upper of these parts forms a support for the lower one and is itself held in place by the connection of the stem to the bowl, the bowl being provided with a short stub stem 8 for spacing the shell from the side walls of the bowl proper so as to provide a heat insulating and air circulating space between the bowl and shell.

In the top of the upper shell part 6 there is provided a series of holes or vents 9 through which the air is drawn into the pipe when it isv smoked and which, as will be apparent, passes downwardly around the bowl and then upwardly through the tobacco or fire chamber and into the users mouth by way of the stem 4. In accordance with such provision the incoming air is made not only readily available for supporting the combustion of the tobacco but also functions to cool the side of the bowl.

To facilitate the filling, lighting and empty ing of the pipe, the lower section I of the bowl encasing shell is connected to the upper section 6 in such way that it can be readily removed but at the same time so that it will be firmly held in place when attached to it. While various means may be employed for this purpose such is accomplished in the disclosed embodiment of the invention by the means shown best in Fig. 6. In accordance with such construction the lower end of the upper shell part 6 is crimped inwardly to provide it with a shallow retaining groove II. In this there is mounted a small expansible or split wire ring l2. The upper edge of the lower shell part 1 is in turncrimped inwardly toprovide a curved upwardly disposed but outvvvardly projecting lip I3 which is of slightly greater outside diameter than the inside diameter of the ring I2 but sufiiciently yieldable to permit its being snapped into the ring supported by the crimped edge I l of the upper shell. By such a connection the lower shell part 1 can be easily snapped. into the upper one and removed by a. relatively small force and at the same time be firmly held in place when connected.

Since the outer shell does not in any way come in contact with the burning tobacco or any appreciable amount of the smoke produced thereby which is drawn into the mouth it may, as previously stated, be made of any kind of material desired. However, as it is desirable to make the pipe as light as possible it is preferably made of some very light material which has sufficient strength to be capable of withstanding rough usage such as a pipe frequently encounters. For these reasons some such material as a strong 5 aluminum alloy or the like is recommended and the outer surface thereof is treated with any suitable coating to give the pipe a pleasing appearance. It may of course also be made in various attractive shapes.

It will also be appreciated that inasmuch as the bowl I is protected as it is by the shell and maintained at a low temperature by the air drawn through the pipe it can be made relatively light to further reduce the weight of the pipe.

In addition by attaching the shell and stem to the bowl in the manner described a number of 725 7 As a further feature of the invention a grid I4 is provided to firmly hold the tobacco in place in the bowl as it is consumed. While such an element as will be apparent may take various forms it is here illustrated as being made of spring steel wire and formed substantially in the shape of a pancake coil having an outer diameter slightly less than the inner diameter of the tobacco chamber and a centrally elongated portion I la. by means of which it is yieldably urged into the bowl. When used it is mounted in the lower shell with its fiat portion disposed in the tobacco chamber. For retaining it in place a mushroom shaped boss I5 is provided in the base of the lower shell part I and the lower end of the spring Ma so formed as to be snapped onto or otherwise secured to this boss.

In the modification of the invention illustrated in Fig. 3 a bowl is provided which comprises a base portion la and a porous wall portion IS, the 5 latter being mounted in a groove I! cut in the lower end of the base 1a.. In such form of the invention it is contemplated that tobacco'rolled in pellets like cigarettes as shown in Fig. 8 will be used. Hence a solid bowl wall is not required, permitting the use of a wire gauze or the like for the wall portion of the bowl whereby the weight of the pipe is further reduced. To retain the pellets ["8 in the bowl the lower portion of the chamber in the base la is tapered slightly at 19 to grip the upper end of the pellet when pressed into it.

In this latter form of the pipe, which is intended more particularly for use as a ladys pipe, the grid M may also be used as well as in the previously discussed type although it may be dispensed with in both forms if desired and the pipe satisfactorily used.

- In addition a porous mat or absorbent 20 may be mounted in the top of the shell between it and the upper face of the bowl I and treated with rum or some other flavoring medium to enhance the quality of the smoke in accordance with the invention.

In using such a pipe the lower shell part 1 is removed when it is desired to load it and the pipe then lit in the customary manner. As soon as it is lit the lower shell part I is snapped in place and the pipe turned to its correct position for smoking. When so' assembled there is no possibili-ty of the tobacco or ashes in the pipe falling out nor can the tobacco in it be forcibly burned as frequently takes place when the common form of pipe is smoked in a strong wind or while riding in an automobile.

Furthermore, in such a pipe there is but slight, if any, tendency for moisture to collect in it which makes for a cool dry smoke. In addition, since the tobacco in the inner end of the fire chamber does not become moist, it can be practically completely used, and with no distasteful smoking such as is encountered. when the fire tends to eat into the heel of the load in a common form of pipe.

According to the provisions of the patent statutes, I have explained the principle and construction of my invention and have illustrated and described what I now consider to represent its best embodiment. However, I desire to have it understood that, within the scope of the appended claims, the invention may be practiced otherwise than as specifically illustrated and described.
