6 Claims. (Cl. 131-225) This invention relates to smoking pipes, and more particularly to a means by `which the bit of the pipe is detachably coupled or attached to the stem of the bowl.

One of the obstacles encountered in pipe manufacture is the tendency of the bit, when threadably joined to the stem by conventional methods, to over-turn and thus become disaligned from the stem. The optimum sought is a bit which, when threaded home will be tightly coupled to the stem and at the same time correctly aligned therewith. This result is diiicult to secure with the conventional joinder of the bit to the stem, such as when the usual threaded coupling is used.

It is therefore one of the objects of the present invention to provide means by which the pipe bit can be securely but removably attached to the stem in a manner to insure correct positioning or alignment of the bit with respect to the stem with a minimum of elort.

It is an object of the invention to provide means by which the bit can be easily fitted in position and adjusted in relation to the stem or pipe stummel and to eliminate overturn or misalignment of the bit.

With these objects, and other objects to be hereinafter set forth in view, I have devised the arrangement of parts to be described and more particularly pointed out in the claims appended hereto.

In the accompanying drawing, wherein an illustrative embodiment of the invention is disclosed,

Fig. 1 is a side elevational view of a pipe constructed according to the invention;

Fig. 2 is a side elevational view of the sleeve that is mounted in the end of the stem or stummel;

Fig. 3 is a side elevational view of the bushing that is positioned within the sleeve and which threadably receives the bit extension;

Fig. 4 is a face view of the washer of nylon or of material of similar characteristics;

Fig. 5 is a side elevational view of a slightly modified form of sleeve in that the same is provided with exterior knurling rather than with ran external thread;

Fig. 6 is an enlarged longitudinal sectional view of the parts in position at the junction of the bit and stem or stummel;

Fig. 7 is a transverse sectional view through the sleeve, the view being taken substantially on the line 7 7 of Fig. 8, looking in the direction of the arrows, and

Fig. 8 is a longitudinal sectional view through the sleeve and bushing before the same are placed in assembled relationship.

Re'ferring to the drawing, 1 indicates the bowl of the pipe, and which may be of conventional shape and construction, and the same is provided with the integrallyformed projecting hollow stem or stummel 2, also of known formation. Tightly fitted within the end of the hollow stem 2 is a metallic sleeve generally indicated at 4. To hold the same in place within the end of the stem and prevent its rotative movement therein, the Shank portion 8 of the sleeve may be exteriorly roughened, such as by the screw threads indicated at 9 in Fig. 2, by the knurling indicated at 10 in Fig. 5 or by other means. At one end, the sleeve 4 is provided with an external, radially-extending ange 7 which abuts against the end of the stem or stummel when the sleeve is fitted therein. The sleeve 4 is also provided with a smooth, cylindrical interior 'or bore 11 and fitted for rotative movement therein is a cylindrical metallic bushing 5. The'bushing 5 is provided with a smooth exterior and with an interior-thread as indicated at 14, for threadable engagement with a complementary spiral thread 17 provided on the exterior of the bit extension 16. Said `bit extension is of known form and as shown is of preforated hollowconstruction, and includes a hollow apertured ball 18 at one end.

Provided within the interior of the sleeve 4 adjacent to its flanged end is an annular seat 12 against which a washer 13 is positioned. The washer may be composed of Nylon or of some other material of substantially similar characteristics and one which is slightly compressible `and capable of acting as a friction brake against one end of the bushing 5. As will be seen in Fig. '6, when the bushing 5 is fitted within the sleeve 4, the washer 13 will be confined between one end of the bushing and the annular shoulder 12. After the bushing is placed within the sleeve 4 it is held therein and against longitudinal displacement out of the sleeve, by inturning or deforming the end of the sleeve remote from the flange 7, such inturning or deformation being indicated at 19 in Fig. 6.

From the foregoing, the construction and operation of the described bit-attaching means will be readily understood. The Nylon or similar washer 13 is fitted within the sleeve and positioned against the face of the annular seat 13. The internally-threaded bushing 5 is then inserted into the bore 11 of the bushing 5 so that one end of the bushing abuts against the washer 13 and the Washer is thereupon resultantly conned between that end of the bushing and the seat 12. The bushing 5, washer 13 and sleeve 4 are maintained in the relationship described, and as shown in Fig. 6, by collapsing, inturning or deforming the periphery of the sleeve at the end remote from the flange 7 and as indicated at 19. The sleeve 4 is now firmly forced into the end of the stem 2 until the ange 7 abuts against the end of the stem 2.

In the application of the bit, the threaded member or extension 16 engages with the internal threads 14 in the bushing 5, which thereon acts as a nut, and when the extension 16 is threaded in suiciently, the bushing 5 will revolve with the extension 16. As this occurs, a frictional contact between the end of the bushing 5 and the washer 13 takes place, so that the bit turns stiiy in the stem, yet permits the bit to be manually adjusted and aligned with the stem but prevents subsequent inadvertent disalignment.

Having described a single embodiment of the invention, it is obvious that the same is not to be restricted thereto but is broad enough to cover all structures coming within the scope of the annexed claims.

What I claim is:

l. A pipe comprising, a bowl provided with a stem, a sleeve iitted into the end of the stem, said sleeve being provided with an internal seat, a washer maintained against the seat, an internally-threaded bushing rotatively mounted within the sleeve and having one end frictionally operative against the Washer, said bushing being maintained from axial displacement out of the sleeve by a distorted portion at one end of the sleeve, and a bit having a forward threaded extension tted within the bushing and threadably received thereby.

2. A pipe comprising, a bowl having: a stem, a sleeve fitted within the stem at one end thereof, said sleeve being provided at one end on its interior with an annular seat, a washer disposed within the sleeve against the seat, a bushingrottive within the sleeve and hvipg'ari en d' arranged in Contact with the washer, said bashing being provided with an internal thread, means on the sleeve for conning the bushing within the sleeve, `and a bit having a forward threaded extension iitt'ed the bushing and threadably received thereby.
