Y. Application time 27, 1944,, Serial No. 542,362 2 Claims. 1 V 2 This invention relates to smoking appliances, such as tobacco pipes. (01. 1s1_z02) Its utility is best exem pli?ed in a tobacco pipe, because the tobacco juice therein‘ detracts from the comfort and pleasure of the smoker and has offered problems that have long perplexed the art. One object of the invention is to provide a simple, discardable device of improved inexpen sive construction for absorbing the tobacco juice. Another object of the invention is the provi sion of a device of the nature set forth having improved means comprising a smoke ?ltering and juice absorbingv portion and a vsafety portion for absorption of any excess ofjuice without retard‘ In the drawing: ' ' Figure 1 is a View in side elevation with parts in section showing a tobacco pipe according to the invention. . Fig.2 is an enlarged top plan view of an attach ment embodying the invention. Figs. 3 and 4 are sectional views taken on‘ lines ‘-,‘-3 and 4—4 respectively, of Fig. 2, and Fig. 5 is a plan view of a blank for the attach-' ment with the core thereon in position for assem bling. ' I Referring in detail to the drawing, it!" denotes a device such as a tobacco pipe embodying the in vention. The same may include a pipe bowl I! having an integral stem portion I 2 to which is detachably connected in any suitable manner a mouthpiece stem portion l3. Preferably a me tallic sleeve or lining M is press ?tted into the stem portion I 2, and is provided with an enlarged material. I . Another object of the invention is to construct 20 collar-like member 55 having an internal thread It, The adjacent end of the mouthpiece stem a device of the class alluded to having improved portion is externally undercut to tightly receive’ means comprising a juice absorber of stepped a collar i'i threaded to screw into the member l5. formation, the larger portion of which substan These metallic elements 14 and i’! are provided tially?lls the cross section of the pipe stem to to permit the use of a large bore in the stem por , also ?lter the smoke, and the smaller portion of tions [2, l3 and, to afford adequate strength at which permits free flow of the ?ltered smoke and vthe joint.
