United States Patent O 3,319,634 PIPE CLEANER DEVICE Sumas Payne, 8522 Maryland Ave., Chicago, Ill. 60619 Filed Nov. 16, 1964, Ser. No. 411,503 1 Claim. (Cl. 131-246) This invention relates broadly to a set of smokers accessories and, more specifically, to pipe appliances which are designed to loosen and remove any deposits in the bowl of a tobacco pipe.

The principal object of the present invention is to provide a novel tobacco-pipe cleaner distinguished by a pair of scraper arms sustained in relatively-yielding relation adjacent the end of a handle.

A second object of the invention is to provide a smokers article of the type aforementioned which is composed of several parts which will, when assembled, provide a tool for scraping out the layer of hard ash that forms on the inside of a smoking pipe bowl.

A third object of the invention is to provide a twin blade scraper having novel convex abrasive type outer surfaces and cutting edges, the blades being adapted to scrape the cake from the inside of a pipe bowl when rotated therein.

Further objects of the invention of the class described are to provide a pipe bowl cleaner that is easy to use, versatile, pleasing in appearance, simple to manufacture, and is adaptable for use with many dierent sizes, types and styles of pipe bowls.

Other objects will be in part apparent and in part pointed ou-t specifically hereinafter in connection with the description of the drawing that follows, in which:

FIGURE l is a side elevational View of a modified type of pipe cleaner of this invention, the cutters being resiliently activated outwardly by a compression spring;

FIGURE 2 is a side view of the pipe cleaner shown in FIG. 1, with parts in section, a portion of the pipe bowl shown by dotted lines;

FIGURE 3 is an end view of the handle portion of the pipe cleaner shown in FIG. 2;

FIGURE 4 is a vertical view of the cutters assembled with the free end portions thereof within the spring housing of the handle, the housing shown in section;

FIGURE 5 is a bottom view of the spring housing;

FIGURE 6 is an exploded view of the pair of cutters shown in FIG. 4.

Referring to these drawings in detail, in which similar reference characters correspond with similar parts throughout the several views, and in which the pipe is shown merely to show the application and use of the pipe cleaner set at a glance, the invention consists in the construction and arrangement of parts which will now be described as follows:

Referring to FIGURES 1-6, a reaming device is shown wherein the reaming blades are resiliently forced apart from each other by a compression spring; they are not rigidly held by a securing bolt. The device 55 shown by FIGURES l, 2 and 3 consists of a handle 61, a scraper 62 and spring housing 63 with associated parts. The handle 61 has a rounded free end portion at one end and the spring housing 63 at its opposite end integrally secured thereto. The distant wall 64 of the housing is formed with two T shaped slots 65 and 66 spaced longitudinally ice away from each other, the cross type portion of the T shaped openings extending transversely of the spring housing wall 64. The carbon Scrapers 67 and 68 are provided with longitudinal convex abrasive type ribbed surfaces with hub portions 70 and 71 at the outer ends carried upon a pivot pin 69. The free ends 72 and 73 of the Scrapers 67 and 68 are of square shape with flat outer and inner surfaces having confronting nodes thereon forming supporting to contact the opposite ends of one common compression spring 75 assembled within the spring housing 63 and between said scraper ends 72 and 73. It is clear that when the user grasps the handle 55 and inserts the Scrapers 67 and 68 into the bowl chamber 60 of bowl 46, the Scrapers 67 and 68 will move toward and away from each other according to size of the ash coated bowl chamber 60.

Having thus described the several useful and novel features of the pipe cleaner of the present invention, it will be seen that the many worthwhile objects for which it was designed have been achieved. While only a single embodiment of the invention has been illustrated in the accompanying drawings, we realize that certain changes and modifications therein may well occur to those skilled in the art within the broad teaching hereof; hence, it is my intention that the scope of protection afforded hereby shall be limited only insofar as said limitations are expressly set forth in the appended claim.

I claim:

An expandable smoking pipe bowl cleaner comprising, an elongated handle with an integral enlarged hollow head chamber at one end thereof forming a spring housing, a cylindrical coil spring arranged within said head chamber, a pivot means, and a reamer means embodying two longitudinally curved scraper arms pivoted by said pivot means at end portions thereof remote from said head, and having cutting edges adjacent to the said pivot means and extending along the outer edges of said scraper arms toward the terminal free ends thereof, said head chamber having a at wall arranged at iight angles relative to the axis of said handle and formed with two T- shaped slots spaced longitudinally away from each other, one portion of the slots extending transversely and adjacent the ends of said ilat wall, the leg portions of said slots extending longitudinally in alinement with each other and parallel to the sides of said wall, the terminal free ends of said arms being assembled with said head chamber whereby they extend through the spaced apart T- shaped slots and into the interior of said head chamber, the terminal free ends of said arms being substantially dat and enlarged relative to the width of said arms and of substantially square Shape having flat outer surfaces and inner surfaces having confronting nodes thereon, and coil spring being arranged and supported solely by and upon said inner surfaces between the terminal free ends of said pair of arms, the ends of said coil spring being in pressing engagement with the inner surfaces of said terminal free ends of said arms and yieldably resisting any change in position of either of said arms toward each other, but permitting change of position of said arms away from each other and travel within the leg portions of said slots whereby said cutting edges of said arms will come into yielding engagement with the walls of the pipe bowl when in use therewith.
