3 Claims.

Our invention relates to smoking pipes, and has among its objects and advantages the provision of improved cleaning and filtering facilities for such pipes.

In the accompanying drawing:

Figure 1 is a side view of the pipe;

Figure 2 is a longitudinal sectional view;

Figure 3 is a top view of a fragment of the stem structure;

Figure 4 is a perspective view of a filter element;

Figure 5 is a sectional view of the filter; and

Figure 6 is an enlarged vertical sectional view of the rear end of the bowl.

In the embodiment of the invention selected for illustration, we make use of a pipe structure having the usual bowl l0, stem l2 and mouthpiece I4. An axial bore I6 is provided in the stem 52 to frictionally receive the shank l8 of the mouthpiece l4. Coaxial smoke passages 20 are provided in the stem l2 and the mouthpiece M, with the passage the stem extending through the rear wall of the bowl, in addition to its communication with the bowl.

A flat face 22 is formed on the bowl ll] against which a closure plate 24 is held firmly to close the passage. This plate is pivotally connected at 26 with the bowl, and is normally yieldingly latched in its closed position by a projection 21 struck from the plate to project into a recess 28 in the bowl. The plate is resilient to resist permanent distortion when being flexed to dislodge the projection from the recess.

An enlargement 3!) is formed on the stem l2 and provided with flat top and bottom faces 32. This body is of generally cylindrical contour when viewed in Figures 1 and 2 and is provided with a bore 34 extending throughout its full length and through the flat faces 32. We prefer to center the bore 34 on the axis of the passage 20 at right angles to the passage, with the passage 20 intersecting the bore at equal distances from its ends.

To close the ends of the bore 34, plates or covers 36 lie in close fitting engagement with the flat faces 32. These covers are pivotally connected at 38 with the enlargement 30, and each cover is latched in its closed position by a lug 4i] struck from the cover to lie in a recess 42 in the enlargement 30. Both covers are flexible in the same manner as the cover 24. To facilitate opening and closing of the covers, each is punched to provide 2. lug 44 constitutin a thumb nail abutment.

In the bore 34 is removably contained a filter body 46 completely filling the bore and provided with a plate-like core 48 paralleling the axis of the body and arranged in right angular relationship with the passage 20. While the core extends from side to side of the body 46, its ends terminate short of the ends of the filter body.

This constrains the smoke to enter the side of the body 46, flow axially thereof toward the ends of the body and then axially in reverse directions for continued flow through the smoke passage. Thus the smoke is caused to flow through a relatively large mass of filtering material in a filter body of relatively small proportions.

An important feature in our invention resides in the fact that the bore 34 crosses the smoke passage 20 and is open at both ends. This provides a construction wherein a smoke passage of nonuniform contour may be easily cleaned. The passage 20, when the filter body is removed, comprises a bore of uniform diameter and may, therefore, be easily cleaned. Similarly, the bore is easily cleaned by merely pressing the filter body from the bore 34 and then wiping the bore dry. Because of the position of the passage 20 with respect to its intersection of the bore 34, the latter constitutes a well effective in its retention of free flowing moisture, which naturally gravitatesto the bottom of the well, both in the presence or absence of filtering material.

Without further elaboration, the foregoing will so fully illustrate our invention, that others may, by applying current knowledge, readily adapt the 7 same for use under various conditions of service.

We claim:

1. In a smoking pipe having a stem and a mouth piece each provided with a smoke passage and said passages being in axial alignment, said stem being provided with an enlarged bore crossing and intersecting said passage at right angles to provide a well, said bore traversing said stem and being open at its ends, covers on the stem to close said bore atits ends, filter means in said bore and removable from either of its ends, and a core extending diametrically through the filter means transversely of the passage, but terminating short of the ends of the filter means.

2. In a smoking pipe having a stem provided with a smoke passage, said stem being provided with a bore crossing and intersecting said passage to provide a well, said bore traversing said stem and being open at its ends, means coacting with the stem to close said bore at its ends, said means comprising flat faces on the stem intersected by the bore, and covers pivoted on the fiat faces of the stem and movable to positions over or to one side of each of the ends of the bore. 3. In a smoking pipe having a stem provided with a smoke passage, said stem being provided with a bore crossing and intersecting said passage and extending the same direction to either 5 side of the smoke passage to provide a well, said bore traversing said stem and being open at both ofits ends, covers on the stem to close said bore at its ends,- fiat faces onthe stem intersected by the bore, the covers being pivoted on the flat 4 faces of the stem to be moved to positions over or to one side of the bore, coacting formations on the stem and said covers to latch the covers in their bore closing positions, a bowl connected
