Patented July 21,*1953 3,646,052... l CONNECTION Fon THE BITS. 0F. SMOKINGPIPESI Jerome Gevi-rina'n, Brooklyn, N. vY. Application September 30,1949, Serial No. 118,951

The present invention relates to a smokers pipe which generally consist of a bowl and bowl stem, a bit having a mouthpiece section at its end, andfmeans for connecting the bittoliihbowl stem.

The object of the present invention is to provide a `.smokers pipe consisting of a bowl and bowl stem, a bit, and threaded connections intermediate the bit and the bowl stem enabling a tight t between the said members and at the same time enabling the bit to be turned in a given direction, vwithout changing the tight i'lt between the bit and the bowl stem, in order that the bit `may be accurately positioned, with the flattened portion of the bit disposed `at a right angle to the axis of the bowl.

The specic object of the invention is to provide a smokers pipe of the stated character which possesses a predetermined frictional resistance between the bit and the bowl stem, which will maintain that condition, which will be capable of easy assembly, and which 4will be of low cost.

The invention will be described with reference t relatively to the bowl stem; j

Figure 2 is a View similar to Fig. 1 showing the bit having been turned to a tight fit relatively to the bowl stem and yet out of proper position, requiring 90 rotation and to the position of Figure l for proper alignment.

Figure 3 is an enlarged fragmentary longitudinal section taken on the line 3-3, Figure l;

Figure 4 is a composite enlarged view showing the bit and bowl stem connecting elements separated and in proper line position for assembly.

Referring to the drawings, I have shown at l the bowl of the smokers pipe it having a bowl stem 2, the bit being indicated at 3.

Referring to Figure 3, it will be seen that the 'bowl stem is formed with a chamber 4, which receives the connector elements 5 and 6. The connector element or tube 5 is an externally threaded tube having a cylindrical portion, the latter having a smooth surface and a knurled head 1. The connector element 6 is a smoothsurfaced sleeve which is threaded on to the end of the connector element 5. It is preferred that the said sleeve be formed of a relatively rm material such as hard rubber or a plastic composition. It will have a smooth surface, and at the same time it will bear upon `the Wall of chamber 4 with a desired friction.

l ironing. (cifrar- 225) 'Ihe connector element 5 is apertured to form -asmall passageway, and the knurled head IY is Apressed into a chamber formed in the end of the Therefore continued clockwise` movement of the connector element 5 will compel rotation of the sleeve. The force required to effect such continued rotation of the sleeve will, of course, be substantially greater than that required in unthreading the connector element 5 from the sleeve. Therefore in disassembling the bit from the bowl stem, counterclockwise rotation of the bit will withdraw the connector element 5 from sleeve 6, the sleeve remaining in position within chamber 4.

A threaded member is employed to serve as a back-up for the sleeve. To that end I have provided an externally threaded member 8 having a flanged head 9. Thus when sleeve 6 has been pressed into chamber 4, member 8 may be threadedinto that chamber, as shown in Fig. 3, until flange 9 is brought into abutment with the end of the bowl stem. At this point the bit, with the projected externally threaded and shouldered tube 5 will be brought into position and the tube threaded into the sleeve 6, preferably by clockwise rotation, until the point is reached at which relative rotation of sleeve 6 and tube 5 stops, and the tube and sleeve virtually become so interengaged as to provide, for all practical purposes, a single member which can be rotated by overcoming the frictional resistance between sleeve 6 and the wall of the chamber in the bowl stem indicated at 4.

It is not essential that tube 5 be threaded in friction sleeve 6.

The formation of annular shoulder 1:1: on the tube 5 has special utility in that it provides a stop or abutment between the tube and the friction sleeve 6.

'Ihe alignment between the bit and the bowl stem is eected according to this invention by inserting the knurled head 1 into the bit 3, next the threaded member 8 is pushed into place onto the smooth portion of connector element 5, then the rubber sleeve 6 screwed onto the threaded until the desired alignment is attained. When. the bit and connector element 5 are disconnected as a unit from the bowl stem 2, thegsleeveY 6.1is re tained within the stem 2 by the threaded-meurber 8.

ofY the elements constituting the embodiment illustrated in the drawings, without departing` from the spirit of the invention.
