HENRY B. BARTON, OF ST. LOUIS, MISSOURI.

TOBACCO-PIPE.

SPECIFICATION forming part of Letters Patent No. 657,019, dated August 28, 1900. y Application filed August 28, 1899. Serial No. 728,702. (No model.)

To all whom it may concern:

Be it known that I, HENRY B. BARTON, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful Improvement in Tobacco-Pipes, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a new and useful improvement in tobacco-pipes, the objects being to construct a pipe in such manner that the saliva will not flow from the mouth down the stem and dampen the tobacco in the bowl or become contaminated with nicotin and be drawn back into the mouth and also to construct a pipe in such manner that by removing a cap-piece and blowing air through the mouthpiece of the pipe a suction is produced which causes the smoke to be drawn from the bowl through a duct leading therefrom and ejected through a separate duct to the atmosphere, thereby forcing and drawing any accumulation of saliva, moisture, or small particles of tobacco from the ducts in the stem of the pipe.

Vith these objects in view the invention consists in the construction, arrangement, and combination of the several parts, all as will hereinafter be described, and afterward pointed out in the claims.

I attain the objects just referred to by the arrangement and construction of the several parts of my improved tobacco-pipe, as is illustrated in the accompanying drawings, in which*- Figure lis a vertical longitudinal sectional view of myimproved tobacco-pipe. Fig. 2 is a plan view of the same, partly in section; and Fig. 3 is a vertical longitudinal sectional view of a slightly-modified form of my improved tobacco-pipe.

Like characters refer to like parts throughout the several views.

In the drawings, A represents the bowl, and B the mouthpiece, of my improved tobaccopipe.

In Figs. l and 2, C represents a section of the stem which when properly secured to the bowl A and mouthpiece I3 form my im proved pipe.

The bowl A is provided with the usual duct a, which is in axial alinement with and opens into a screw-threaded recess a. The section of the stem marked C is provided with a screwthreaded portion c, adapted to cooperate with and engage the screw-threaded recess a. On the other end of the stem-section C, or the end opposite that upon which the screwthreaded portion c is formed, is provided a screw-threaded recess c', and formed on one end of the mouthpiece B is a screw-threaded portion h, adapted to coperate with and engage said recess c formed in the section C.

Extending inwardly from the screw-threaded recess c is a recess c,'and opening into said recess c at, preferably, the lower side and theinnerend is what I will term a pocket du ct 0', said pocket-duct c'" being arranged at such an angle, which is preferably downwardly and toward the bowl, as to cause any saliva which might gather in the recess c to settle thereinto.

c"" indicates a duct formed longitudinally through the section C, one end of said duct opening into the recess c", while the other end of said duct terminates at the end of the screw-threaded portion o, at which latter point it registers with the duct a. of the bowl.

Theinner end of the mouthpiece B is preferably provided with a teat or nozzle b', the end of which nozzle is, when the pipe is prop'- erly assembled, directly in axial alinement with the pocket-duct 0. The duct b" in the mouthpiece Bis so formed as to pierce the teat or nozzle b and by a suitable curve is caused to aline with the pocket-duct c". (See Figs. 1 and 3.)

D represents a cap-piece, which may be formed of any suitable material and is designed to close the outer end of the pockets duct c", said cap being adapted to be removed when it is desired to free the pipe of saliva, moisture, nicotin, or other objectionable matter.

It will be observed from a glance at the drawings that when the bowl is filled with tobacco and ignited and the smoker draws upon the mouthpiece in the usual manner the smoke passes through the duct b into the IOO mouth; but any saliva which may run from the mouth into the stem or, rather, through the duct b is arrested by the recess c and the lll pocket-duct c and is thus prevented from entering the ducts 0" and a and commingling with the tobacco in the bowl.

When it is desired to clean the pipe or cause a current of air or smoke to pass'through the several ducts to remove saliva or other deposits, the cap-piece D is removed and the smoker blows through the mouthpiece, which action vcauses the saliva, dac., to be forced through the duct b" into and through the pocket-duct 0 to the atmosphere. This action produces in the recess c a partial vacuum, which vacuum draws the smoke and air from the bowl A thereinto and through the instrumentality of the blast of air through the duct b, which is, as before stated, directed into and through the pocket-duct 0'", said smoke and air being ejected from said recess c through said pocket-duct c" to the atmosphere. From the above it will be seen that my improved pipe can be quickly and thoroughly cleaned without necessitating the extinguishment of the ignited tobacco or removing the same from lthe bowl.

In Fig. 3 I have illustrated a slightly-modified form of pipe, wherein I have formed the stem portion, which contains the recess c and the pocket-duct c", integral with the bowl, thus dispensing with one joint and one section of pipe. In other respects this pipe is identical in construction to that illustrated in Figs. 1 and 2 of the drawings.

Iam aware that minor changes in the arrangement, construction, and combination of several parts of my device can be madeand substituted for those herein shown and described without in the least departing from the nature and principle of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In a tobacco-pipe, the combination` with the bowl formed with a smoke-duct leading therefrom, of a stem formed with a smokeduct substantially in axial alinement with the smoke-duct from the bowl, the Vacuumchamber into and from which said ducts lead, a pocket-duct leading from the bottom of the vacuum-chamber, and arranged at an angle to the axis of the ducts first mentioned, a removable cap or cover for closing the lower end of said pocket-duct, and a teat or nozzle formed on the inner end of the stem and projecting into the vacuum-chamber, said teat being formed with a portion of the smokeduct of the stem, which at this point, is curved so that at the extremity of said teat, said duct is in axial alinement. with the pocket-duct and adjacent thereto, whereby, in one operation the duct'in the stem is used as a draftduct, and in another, as an injector for injecting the material from the smoke-duct of the bowl and stem into said pocket-duct, said blast being conducted into and through the pocket-duct; substantially as described.

2. In a tobacco-pipe, the combination of a bowl, a stem having a smoke-duct leading from the bowl to an enlarged vacuum-chamber c in the stem, a pocket-duct extending downwardly from said Vacuum-chamber,a removable closure closing the lower end thereof, and a teat or nipple extending into said vacuum-chamber opposite the smoke-duct from the bowl and having a duct connecting with a duct in the mouth end of the stem and terminating at a point directly opposite and adjacent to said pocketduct, and directed in line therewith whereby when said closure is removed and a blast produced in the stem an injector eEect is produced drawing matter from the bowl end of the smoke-duct and forcing the same through the pocket-duct, substantially as described.

In testimony whereof I hereunto affix my signature, in the presence of two witnesses, this 26th day of August, 1899.

HENRY B. BARTGN.
