TOBACCO-PIP E.

SPECIFICATION forming part of Letters Patent No. 642,445, dated January 30, 1900.

Application filed July 22, 1897. Serial No. 645,633. (No model.)

To all whom it may concern.-

Be it known that I, FRANK A. HAUGH, a citizen of the United States of America, and a resident of Albia, in the county of Monroe and State of Iowa, have invented a new and useful Tobacco-Pipe, of which the following is a specification.

The object of this invention is to provide improved means whereby to construct a tobacco-pipe so that the stem and bowl of said pipe may be conveniently and readily cleansed of all impurities, nicotine, ashes,and other substances which may become lodged or settled therein during the use and operation of the pipe and so that said substances will be retained in the bowl-cavity and smokebore of the stem and prevented from working out and soiling the hands and clothes of the smoker.

My invention consists in the construction, arrangement, and combination of elements hereinafter set forth, pointed out in my claim, and illustrated by the accompanying drawings, in which- Figure 1 is a side elevation of the complete pipe. Fig. 2 is a plan showing the bowl and stem portion of the pipe in an open position, the screwing-band being shown in section. Fig. 3 is a horizontal section through the bowl of the pipe on an enlarged scale. Fig. 4 is a cross-section through the stem thereof on an enlarged scale.

In the construction of the device, as shown, the numerals 10 11 designate like sections or members of a pipe bowl and stem, each of which members is formed in a single piece and provided with a cavity 12 and a groove 13, communicating with the bottom of said cavity and extending therefrom axially of the stem to the outer end of said stem. When the members 10 11 are assembled, as shown in Fig. 1, the cavities thereof form a bowl in which may be placed tobacco for smoking pur poses, and the grooves 13 form a bore, duct, or conduit leading from the lower end of the bowl to the outer end of the stem. Dowelpins 14 15 are mounted in the member 10 and project from the face thereof in such a manner as to enter dowel-seats 16 17 in the member 11 when the members 10 11 are approximated and contacted. By this means slipping of one member upon the other when the hinge has become loose by wear is prevented, an accurate seating of the members secured, and the retaining-ring, hereinafter described, relieved of vertical strain. Grooves 18 19 are formed in the marginal edges of the member 11 and open partiallyinto the groove l3,and strips or sections 20 21 of asbestos are mounted in said grooves and project slightly therefrom, so as to enter corresponding and mating grooves 22 23 in the member 11 when the members 10 11 are approximated and contacted. The outer end portions of the stem-sections are reduced and exteriorly screw-threaded to receive the interiorly-screw-threaded mouthpiece 24. A screw-thread is formed on the exterior of the bowl-sections near the top thereof, and a retaining-band 25, also provided with a screw or lip 26, is mounted about and upon the bowlsections and held thereon by the engagement of the screw or lip with the screw-thread. The retaining-band when in final position is lo-' cated approximately at the center or a little above the center of the-bowl portion of the pipe. A hinge 27 is positioned on the menu bers 1O 11 near the line or demarcation between the stem and bowl portions and connects said members.

In practical use the members 10 11 are con t'act'ed and held together by the retaining-band and the mouthpiece, and when it is desired to clean the pipe after use the retaining-band and mouthpiece are removed, the members positioned, as shown in Fig. 2 of the drawings, and the bowl and grooves cleaned in any desired manner. I

By the use of the strips of asbestos provision is made for an approximately air-tight joint between the members 10 11, and by the use of the hinge 27 provision is made to prevent the displacement or removal of either of the members from the other, the dowel-pins acting in conjunction with the dowel-seats t0 aline andretain in alinement and proper positioning the said members.

The arrangement of the grooves 18 19 at the marginal edges of and openinginto the cavities l2 and grooves 13 and the projection of the packing strips from the packinggrooves of one section into the corresponding grooves of the other section when said sections are closed are also of material importance, as the strips thus tightly close the inlets of all crevices and prevent the ashes, nicotine, oil of tobacco, and saliva from working outwardly between the two sections of the pipe and running to the end of the stem 01' top of the bowl or other points where escape is ordinarily possible and gummingthe exterior of the pipe and soiling the hands or clothes of the smoker. By this means the impurities are retained in the grooves, from which they may be readily removed when the pipe-sections are opened, and the contacting faces of said sections are maintained in a cleanly condition. This would not be the case if the packing-strips did not project from one groove into the other or were placed midway of the bore-grooves and outer edges of the meeting faces of the pipe-sections for obvious reasons. Furthermore, by employing asbestos as the packing medium I am enabled to locate the packing-grooves on the inner marginal edges of the bowl-sections and to obtain other advantages, as this material is light and resilient and retains its shape, is not alfected by heat or the chemical constituents or residue of the tobacco, will last longer than rubber, cork, or other which communicate at their innenlongitudinal edges with the said bore and bowl-cavity, means for securing the sections when closed, an absorbent fireproof packing located in the said seats and overlapping the joint formed between the meeting faces of the said parts, and having their inner longitudinal edges flush with the sides of the said bowl-cavity and bore, said packing being secured at one edge in the groove of one part of the pipe and having its opposite edge free and adapted to be detaehably fitted into the groove of the other part of the pipe, substantially as specified.
