MARY A. BARGER, OF HOPEDALE, ILLINOIS.
T 0 all whom it may concern:
Be it known that I, MARY A. BARGER, a citizen of the United States, residing at Hopedale, in the county of Tazewell and State of Illinois, have invented certain new and useful Improvements in Smoking-Pipes; and I 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 which it appertains to make and use the same.
My invention relates to certain new and useful improvements in smoking pipes, and particularly to that type designated as safety pipes, such as shown and described in Letters Patent No. 711,691, granted to Robert N. Barger, on the 21st day of October, 1902, and in which the tobacco is held in a container tube located within two-part receiver provided with a suitable mouth piece, and with a series of apertures through which the necessary amount of oxygen is supplied to sustain combustion. In pipes of such construction the air is drawn directly from the point of ignition through the tobacco receptacle to the mouth of the user and is received therein in a somewhat heated condition.
My invention has for its objects to conduct the smoke resulting from the burned tobacco to a locality distant from the mouth piece and then returned in order that it maybe cooled before it is received in the mouth; and my invention consists in the details of construction hereinafter more fully described.
In order that those skilled in the art to which my invention appertains may fully understand its advantages I will proceed to describe the same, referring by numerals to the accompanying drawing, in which Figure 1 is a perspective view of a pipe embodying the features of my invention and in closed condition. Fig. 2 is a vertical, perspective view with the two parts separated, and with the tobacco cavity supplied with a charge of tobacco and in condition to be ignited. Fig. 3 is a central longitudinal section on the line (5-?) of Fig. 1. Fig. 4- is a similar section and showing the tobacco cavity provided with a removable receptacle composed of pipe clay or other suitable material. Fig. 5 is a detail perspective view of the outer portion of the body.of the pipe and showing the seat for the slip joint be- Speeification of Letters Patent.

tween the two parts of the body; and Fig. 6 is a perspective view of the ferrule or band for closing the joint between the two parts of the body and providing means for the introduction of the necessary amount of oxygen.
Similar reference numerals indicate like parts in the several figures of the drawing.
1 is the upper and 2 the outer portion of the body of the pipe which is of cigar shape and preferably composed of wood pulp, molded into form, although other suitable plastic material may be used. The part 1 is formed with a smoke channel 3 communicating with a mouth piece 4L secured by a screw thread in the outer end of the part 1, as clearly shown, and with a finishing and strengthening metallic cap 5 between the two. The channel 8, as clearly shown in Figs. 3 and 4:, extends from axial relation with the mouth piece in a curved and lateral direction into coincidence with another smoke channel 6 at one side of the part 2 of the body, and is formed with a cavity 6 which when the parts are in closed condition forms a chamber above the tobacco receptacle or cavity in the other part hereinafter referred to, and constitutes an air chamber.
7 is a metal ring or band secured in any suitable manner to the outer extremity of the part 1 and adapted to surround closely the adjacent or inner end of the part 2, when the parts 1 and 2 are in the position shown in Figs. 1 and 2, and to close the circumferential joint between them, and is provided with air orifices 7*. The part 2 is formed at one side with a projecting longitudinal seat 8 for a swivel connection 9 between the parts 1 and 2. This swivel connection is preferably secured by a screw thread at one end with the part 1, and its opposite end is preferably reduced in diameter and adapted to traverse or move longitudinally through the seat 8 and within the smoke channel 6 of the part 2, and is formed with an axial smoke channel communicating with and joining the smoke channels 3 and (3, as clearly shown in Figs. 3 and 41-.
The length of the swivel 9 and the width of the ring or band 7 are relatively such that when the parts 1 and 2 are separated as shown in Figs. 2 and 4 the band will rest upon the shoulder 8 and the swivel will still remain in its seat in the part 2, so that the tobacco cavity or bowl 10 in the part 2 may be charged with tobacco. The smoke channel 6 of the part 2 communicates with the bottom or outer extremity of the tobacco cavity 10 or with an orifice 11 in the end of a removable tobacco receptacle 12, as shown in Fig. 4.
Then it is desired to charge and ignite my improved pipe the )arts 1 and 2 are separated by longitudinal movement and to such extent that the outer or face extremity of the, ring or band 7 passes the inner eX- tremity of the part 2 and comes into alinement with the outer extremity of the shoulder or seat 8, whereupon the parts are swiveled upon the connection 9 into the position shown in Figs. 2 and 4, thus exposing the tobacco cavity or receptacle, while at the same time the smoke channels 3 and 6 are both in communication with the axial channel in the swivel 9 and the tobacco is ignited and combustion started by draft upon the mouth piece 4, air being supplied at the open upper or inner end of the part 2 in an obvious manner.
When the tobacco has become sufficiently ignited the parts 1 and 2 are swiveled into axial alinement upon the swivel 9 and moved longitudinally toward each other until the parts assume the positions shown in Figs, 1 and 3, in which position the ring or band 7 constitutes a joint between or continuation of the two parts, and the air orifices 7 X which are then radial to the space between the adjacent ends of the two parts 1 and 2 permit the ingress of sufiic-ient air to maintain combustion.
From the construction shown and described it will be seen that the smoke is drawnthrough the tobacco and to the outer extremity of the pipe and then returned inthe opposite direction to the mouth piece l, thus giving it time and opportunity to cool.
This improved pipe has all the characteristics of safety ascribed to the construction shown in the Letters Patent hereinbefore referred to and may be carried in a lighted condition within the pocket or adjacent to inflammable bodies, and may likewise be used where ordinary pipes could not be used, and without the emission of sparks or ashes, or extinguished by excessive drafts.
While the particular construction and material described is preferable I do not wish to be limited in these respects as the genus of my invention resides in the two-part body joined by a rotative and longitudinally movable connection forming a continuation of smoke channels extending from the outer extremity of the pipe to the mouth piece,
I-Iavin-g described the construction and ad- 3 vantages of my improved pipe, what I claim I and smoke channels extending from the outer extremity of one part to the mouth 1 piece of the other, connected together by a rotative and longitudinally movable connection constituting a continuation of the smoke channel, and a ring or band secured to one of the parts and provided with radial air orifices and adapted to bridge the adjacent ends of the two parts of the body, substantially as hereinbefore set forth.
2. In a pipe such as described, and consisting of a two-part body, one formed with a tobacco cavity or receptacle, and each formed with a smoke channel adapted to be brought into communication; a rotative and longitudinally movable joint between the two parts of the body and constituting a continuation of the smoke channels and located in a longitudinal projection or seat on one of the parts and lateral to its axis; and a circumferential band secured to one of the parts and provided with air orifices and adapted to bridge the space between the adjacent ends of the two parts of the body, substantially as hereinbefore set forth.
3. In a pipe such as described, consisting of a two-part body with smoke channels ex.- tending from a tobacco cavity or receptacle in one of said parts to a mouth piece connected with the other through a rotative and longitudinally movable joint; a longitudinal extension on one of said parts latf eral to its axis, and a circumferential band secured to one of said arts and provided with one or more air in ets communicating with the space between the adjacent ends of the two parts of the body, substantially as hereinbefore set forth.
4. In a pipe. such as described and consistvided with smoke channels communicating through said connection; a tobacco cavity or receptacle in one of said parts, and an air chamber in the extremity of the other of said parts; and a circumferential band adapted j'to bridge the joint between the two parts, :and provided with air inlets communicatf ing with the said air chamber, substantially as hereinbefore set forth,
