Application March 2s, issaserial No. 71,437 1 Claim.` (Cl. ISI-_184) My invention relates to improvements in smok ers’ pipes. The objects of my invention are: 1. To provide a simple, easilyl cleaned smok with means for separating the a small bore or opening 2b is provided to permit passage~ of smoke and condensation from the bowl into the stem l. The bowl end of condensed moisture, solutions of nicotine, etc. and saliva, from the smoke, so as to afford a ‘ dry smoke and to prevent solutions being drawn into the mouth with the accompanying disagree able taste; ’ ure 10. l 2. To provide a reservoir to retain the liquids produced in the smoking of tobacco, including saliva, and which may get into the stem of the PIDE; 3. To provide convenient, rapid means for cleaning out such liquids from the stem and reservoir; and, dental displacement, ' Ll. To provide a simple, easily cleaned pipe of , The cap 3 has a cleaning rod 4 united thereto, and this cleaning rod extends preferably ap 10 proximately the full length of the stem and the mouthpiece end da, thereof is widened and curved transversely so as to form a trough or conduit to conduct any saliva that may be introduced 15 therein to the reservoir portion of the bore l, the bore 'l being substantially enlarged for the improved construction. 20 I accomplish these objects by the means illus trated in the accompanying drawing, in which, 20 Figure l is a vertical sectional elevation of my pipe on the middle line of the bowl and stem, but showing the cleaner rod and wiper in full lines; 25 Figure 2 is a detail top View of the cleaner At the inner end of the conduit section 4a I form a small opening 4b to lead the saliva from the conduit section 4a to the reservoir formed 25 by the enlarged portion of the bore 1. The rod 4 may be either flat or round and is preferably made of slightlyresilient material so that it may be readily given a quarter turn as shown in Fig ure 1 which shows a fiat rod 4 with the cap end 30 turned a quarter turn. rod; Figure 3 is a side elevation of the cleaner rod, but omits the notches, 4c; Figure 4 is a top or plan View showing the 30 bore of the pipe in dotted lines; Figure 5 is a side elevation of the stem alone showing the bore and the seat for the bowl in dotted lines; 35 ‘ 1 When a iiat rod d is used and turned as shown Figure 6 is a detail elevation of the bowl; in Figure 1, it provides free passage for the smoke and fluids of condensation or combustion which may be formed in the bowl, from the bowl to the 35 reservoir portion of the bore l. The reservoir portion of the bore 'I is prefer ably cylindrical, but the portion of the bore ex Figure 7 is an enlarged detail section of the wiper, 5; . Figure 8 is an enlarged detail end view of the wiper, 5; Figure 9 is an enlarged sectional View of the 40 mouthpiece on the line 9-9 of Figure 5; Figure l0 is` a section elevation showing an tending through the mouthpiece, is made semi cylindrical in section as shown in Figure 9, so 40 as to retain the curved end, or conduit section #a of the rod 4 in proper position to act as a alternate form of closure member; Figure 11 is an enlarged sectional detail of a portion of the trough of the cleaner rod on the 45 line lI-Il of Figure 3. Similar numerals refer to similar parts throughout the several views. My pipe comprises an elongated stem I having a central bore 1 extended lengthwise through 50 the central portion of the stem. The stem I is provided with a threaded seat or socket iw into which the reduced threaded end 2c of the bowl 2 is seated. The bowl 2 is provided with the usual bore or cavity 2a to hold the tobacco while 55 being, smoked and at the lower end of the bowl, ' conduit for the saliva. In order to clean.the reservoir readily, I at tach to the rod 4 a small cleaning ring or washer 45 5 of rubber, which is secured in place within the reservoir portion of the bore 'l upon the curved end portion 4a of the rod 4 and in order to seat the washer ñrmly upon the same, grooves or notches 4c are formed in the section lla of the 50 rod 4. These notches act to keep the washer in place while the rod is being withdrawn through the bore l and the washer, preferably of elastic material, is made large enough to sweep the 2,134,781 2 sides of the bore 'l so as to clean all fluids and other matter therefrom. In the operation of my pipe, it is filled and lighted in the ordinary manner. As often as desired, preferably at least once a day, the rod 4 is withdrawn by the cap 3 which may be of any desired form to be conveniently grasped, and as the rod 4 is withdrawn, the washer 5 performs the sweeping or scrubbing operation described and the pipe is thoroughly cleaned thereby. The rod itself may be wiped 01T or cleaned in any desired manner before being returned to the pipe, and is then returned to the pipe with the section 4a` seated properly in the mouthpiece. the smoke as it passes through the reservoir, thus insuring a cool smoke. In the form shown in Figure 10, instead of a cap 3 mounted upon the extension of the stern l I enlarge and taper the bore at the bowl end of the stem and insert therein a tapered plug 8 to which the cleaner rod 4 may be united by any suitable means. The plug 8 and the enlarged bore are made to ñt closely so that the plug will be retained in any position in which it may be placed manually and of course, Will hold the rod 4 in the same manner that ‘1t is held by the cap 3 when the cap is used. I claim: In a pipe, a stem with mouthpiece united 15 The cap 3 is then given a quarter turn so as to turn the rod 4 in a position to prevent any ob thereto, a bore extending longitudinally through struction of the bore 2b but if desired, the bore 2b may be made large enough lto avoid any necessity for turning the rod 4, as described. The bore 1 is preferably formed of uniform diameter from the bowl end of the pipe to the mouthpiece, but the mouthpiece end of it is pref large cylindrical section extending through the erably reduced. lin place to close the outer end thereof, and a cleaning rod having one end united to said means and extending through the bore of the stem and mouthpiece, the portion of the rod extending It should be observed that as the smoke passes downward from the bowl into the bore 1 any condensation or fluid products of combustion will naturally gather in the bore 1, the reservoir .por tion thereof being made large enough to accom modate a considerable amount of fluid, while leaving ample room for the passage of the smoke 50 and that a dry smoke will thus be afforded. The size of the reservoir is also preferably made suffi cient to añord a measurable degree of cooling for the stem and mouthpiece having a relatively stem and a reduced semi-cylindrical section ex tending through the mouthpiece, a bowl united to 20 the stem, an extension formed upon the end of the stem adjacent the bowl, closure means re movably united to the extension, adapted when into the mouthpiece being widened and curved to form a trough ñtted into the semi-cylindrical bore of the mouthpiece so as to prevent its turn ing therein.
