.2 Claims. l
Our invention relates to a pipe stem cleaner which is adapted to be used for cleaning the stems of tobacco smoking pipes. More particularly our improvement provides a strip of pipe stem cleaner in a magazine forming a self contained unit which is adapted to be carried in the pocket of the user without crushing or breaking the strip and from which short lengths of the cleaner can be readily dispensed as required for use. More particularly our improvement provides improved features of construction and cooperating parts hereinafter set forth and described. Our improvement also provides an improved method by which the magazine and its load of pipe stem cleaner sections are manufactured, whereby a self contained unit loaded with a frangible strip of pipe steam cleaner can be economically produced by a minimum amount of hand labor and expense.

Our invention includes a magazine or carrying case A, which is loaded with a coiled strip of pipe stem cleaner B, said cleaner strip being dispensed in sectional lengths when withdrawn from the magazine by the user. The strip of pipe stem cleaner as shown resembles a twisted wire core l5 (Fig. 5), composed of metal or other suitable material, between the convolutions of which short brush bristles or threads I6 of substantially reven length are secured transversely to form a swab or brush, this portion of the structure beingy well known and in common use. This feature also is set forth in companion application filed by-De- Witt McCann and Irving Berlin on the 24th day of September, 1945, bearing Serial Number 618,276, upon which the present appli-cation is an improvement. The strip of pipe stem cleaner is apportioned into a series of substantially even lengths or sections I1 suitable for use in cleaning a smokingjpipe stem, as shown in Figs. 4 and 5, each node or apportioning means being formed by transverse weakening indentures or notches such asA I8 in the wire core and by separating or removing a small portion of the brush or jacket I6 at each junction or node between adjacent sections as shown in Fig. 5. The strip thus ree sembles a continuous length of frangible sections at evenly spaced intervals throughout its length. This strip is condensed by forming into a coil C in the magazine A and normally cooperates with the magazine in producing a self contained unit in the following manner.
The magazine A is disk-like in shape and may be made out of plastic or other suitable material'. It has two similar thin wall housing sections 20 and 2| which are formed with peripheral inwardly directed marginal edges 22 and 23. The housing sections are joined together by two engaging coaxially disposed male and female hub mem bers 24 and 25, the member 24 resembling an inner cylindrical stud integral with the section20 and the member 25 resembling an outer sleeve which is integral with the section 2 I, These hub members telescope tightly together. The female hub member is split longitudinally by the slots 26 in its wall to provide resilient claspingsides which engage tightly over the male hub member 24. The female hub member is also of sufcient length to abut by its outer end portion against the inner wall of the housing member 20 and hold the housing members 20 and 2| -with their inturned marginal edges 22 and 23 spaced apart at a suitable distance to provide an annular vorifice or channel 28 which enters the chamber circumferentially within the magazine. The housing sections are locked together when lthe hub members are fully connected by an annular extruded bead or shoulder 29 on theinner portonof the male hub member which snaps into engagement with the female hubmember 25 in an annular groove 30 in the inner surfaceofthe female hub member. When the hub membersare interlocked by the engagement of the shoulder 29 in groove 30 the outer end of the male hub member is spaced from the inner end of the female hub member, thus exposing the inner ends of the slots 26 which connect with the chamber in the magazine for the purpose of providing an anchorage for the inner end of the coil of pipe stem cleaner B as will be hereinafter described.
The interlocking engagement above described is preferably inseparable but may be proportioned and made separable by the application of sufficient force if so desired. When made separable the magazine can be recharged with a coil of fresh pipe stem cleaner.
In the production of our improved pipe stem cleaner unit, the strip B is attached by one end across and through the slots 26 in the inner end portion of the female hub member 25 before the variously modified in construction and used with sections of the magazine or carrier case are joined from within the magazine. By this method the manufacture of our improved self contained pipe stem cleaner unit is expedited and its cost of production reduced to a minimum whereby it is not burdensome from the standpoint of expense to discard the exhausted magazine.
The thin wall sections of the magazine are preferably flexible so that by squeezing their outer portions inwardly together the orifice or channel 28 is contracted and the edges of the adjoining sections are made to engagey and hold the strip vof pipe stem cleaner at each junction or weakened portion of the strip, thus enabling the user to easily break away and remove the outermost section of cleaner for use. When thus segregated and the sections 20 and 2l of the magazine are released the remaining outer end portion of the pipe stem cleaning coil tends to spring radially outwardly a sufficient distance through the annular orifice or channel to enable the user to engage the outer end portion and withdraw anlother section of the strip from the magazine for use.
The width of the annular orifice or channel 2B is slightly in excess of the diameter of the core l5 of the cleaner but is` considerably less than the diameter of the flexible brush portion I6, whereby the protruding end of each section of the strip of cleaner is exposed ready for use. By squeezing the lower portions of the sections of the magazine inwardly the upper portions adjacent tol the protruding end of the cleaner are tilted apart and the orifice or channel thus widened to more easily permit withdrawal lof the cleaner from the coil within the magazine.
Our improved pipe stem cleaner is exceedingly f" Next the body or without weakening indentures, in which event the core of the cleaner can be composed of more readily frangible material, lor the entire strip can be made out of suitable material with or without a core. Also it is within the spirit of the invention that the sections of the strip of cleaner may be merely marked with color or dye spots to indicate the lengths of the sections, or that bloth weakened spots at spaced intervals in the core and color or dye spots may be dispensed with and the strip broken into sections of any chosen length by the user.
In accordance with the patent statutes we have described the principles of operation of our invention together with the construction which we now consider to represent the best embodiment thereof but we desire to have it understood that the construction shown is lonly illustrative and that the invention can be carried out by other means and applied to uses other than those above set forth within the spirit of the invention and the scope of the following claims.
