(Cl. 131-4202) 1 Our invention relates to smoking pipes, and has among its objects and advantages the pro vision of improved cleaning and ?ltering facili ties for such pipes. In the accompanying drawing: 2 , with a plate-like core 48 paralleling the axis of the body and arranged in right angular relation ship with the passage 20. While the core ex tends from side to side of the body 46, its ends terminate short of the ends of the ?lter body. This constrains the smoke to enter the side of the Figure 1 is a side view of the pipe; body 46, ?ow axially ‘thereof toward the ends of Figure 2 is a longitudinal sectional view; the body and then axially in reverse directions for Figure 3 is a top view of a fragment of the stem continued ?ow through the smoke passage. Thus structure; Figure 4 is a perspective view of a ?lter ele 10 the smoke is caused to flow through a relatively large mass of ?ltering material in a ?lter body of ment; ' relatively small proportions. Figure 5 is a sectional view of the ?lter; and An important feature in our invention resides Figure 6 is an enlarged vertical sectional view in the fact that the bore 34 crosses the smoke passage 20 and is open at both ends. This pro 15 In the embodiment of the invention selected vides a construction wherein a smoke passage for illustration, we make use of a pipe structure of the rear end of the bowl. having the usual bowl l0, stem l2 and mouth piece I4. An axial rbore I6 is provided in the stem 52 to frictionally receive the shank l8 of of nonuniform contour may be easily cleaned. The passage 20, when the ?lter body is removed, comprises a bore of uniform diameter and may, the mouthpiece l4. Coaxial smoke passages 20 20 therefore, be easily cleaned. Similarly, the bore is easily cleaned by merely pressing the ?lter are provided in the stem l2 and the mouthpiece body from the bore 34 and then wiping the M, with the passage the stem extending bore dry. Because of the position of the pas through the rear wall of the bowl, in addition to sage 20 with respect to its intersection of the its communication with the bowl. A ?at face 22 is formed on the bowl ll] against 25 bore 34, the latter constitutes a well effective in its retention of free flowing moisture, which which a closure plate 24 is held ?rmly to close naturally gravitatesto the bottom of the well, the passage. This plate is pivotally connected both in the presence or absence of ?ltering mate at 26 with the bowl, and is normally yieldingly rial. latched in its closed position by a projection 21 struck from the plate to project into a recess 28 30 Without further elaboration, the foregoing will so fully illustrate our invention, that others may, in the bowl. The plate is resilient to resist per by applying current knowledge, readily adapt the manent distortion when being ?exed to dislodge the projection from the recess. An enlargement 3!) is formed on the stem l2 ‘ 7 same for use under various conditions of service. We claim: 1. In a smoking pipe having a stem and a and provided with flat top and bottom faces 32. 35 mouth piece each provided with a smoke passage This body is of generally cylindrical contour when and said passages being in axial alignment, said viewed in Figures 1 and 2 and is ‘provided with a stem being provided with an enlarged bore cross bore 34 extending throughout its full length and ing and intersecting said passage at‘right angles through the ?at faces 32. We prefer to center the bore 34 on the axis of the passage 20 at right 40 to provide a well, said bore traversing said stem angles to the passage, with the passage 20 inter secting the bore at equal distances from its ends. To close the ends of the bore 34, plates or cov ers 36 lie in close ?tting engagement with the flat faces 32. These covers are pivotally con nected at 38 with the enlargement 30, and each and being open at its ends, covers on the stem to close said bore atits ends, ?lter means in said bore and removable from either of its ends, and a core extending diametrically through the ?lter 45 means transversely of the passage, but terminat ing short of the ends of the ?lter means. ' 2. In a smoking pipe having a stem provided with a smoke passage, said stem being provided 4i] struck from the cover to lie in a recess 42 in with a bore crossing and intersecting said pas the enlargement 30. Both covers are ?exible in the same manner as the cover v24. To facilitate 50 sage to provide a well, said bore traversing said stem and being open at its ends, means coacting opening and closing of the covers, each is ‘punched to provide 2. lug 44 constituting a thumb nail with the stem to close said bore at its ends, said means comprising ?at faces on the stem inter abutment. sected by the bore, and covers pivoted on the In the bore 34 is removably contained a ?lter body 46 completely ?lling the bore and provided . ?at faces of the stem and movable to positions cover is latched in its closed position by a lug a 2,404,733 4 . .‘ 6 over or to one side of each of the ends of the bore. faces of the stem to be moved to ‘positions over or 3. In a smoking pipe having a stem provided to one side of’ the bore, coacting formations on with a smoke passage, said stem being provided the stem and said covers to latch the covers in with a bore crossing and intersecting said pas their bore closing positions, a bowl connected‘ sage and extending the same direction to either 5 with the stem, said passage having communica side of the smoke passage to provide a well, said tion with the bowl and extending through the bore traversing said stem and being open at both bowl, and a cover means normally closing the of‘its ends, covers on the stem to close said bore passage at its end extending through the bowl.
