8. L. CORSON PIPE Filed Feb. 9 1921 Patented Mar. 2, 1926.

BOLTON L. CORSON, OF PLYMOUTH MEETING, PENNSYLVANIA.

PIPE.

Application filed February 9, 1921. Serial No. 443,579.

To all whom it may mace-m Be it known that I, BOLTON L. CORSON, a citizen of the United States, residing in Plymouth Meeting, Pennsylvania, have invented certain Improvements in Pipes, of which the following is a specification.

My invention relates to improvements in tobacco pipes, the principal object of the invention being to provide means whereby the accumulation of tobacco which invariably forms in the bottom of the bowl may be loosened and entirely separated from the bowl and emptied out without the necessity for employing an external cleaning implement.

The invention will be more readily understood from the attached drawings, in which:

Figure 1, is a vertical longitudinal. section of a pipe made in accordance with my invention;

Fig. 2, is a vertical section of the bowl on the line 2-2, Fig. 1;

Fig. 3, is a detached perspective of the cleaning element, together with its operating handle;

Fig. 4, is a vertical section illustrating a modification of the device within the scope of my invention;

Fig. 5, is a detached perspective of the cleaning element of the modification illustrated in Fig. 4;

Fig. 6, is a View in perspective of a pipe made in accordance with my invention, illustrating, a further modification, and Fig. 7, is a vertical section of the pipe illustrated in Fig. 6.

WVith reference to the drawings, the pipe may comprise the usual wooden or other bowl member 1 from which extends a perforated shank or stem 2. In the base of the bowl I have mounted, inthe present instance, a cleaning element 3 shaped, as shown in Figs. 2 and 3, to conform to the cross setional contour of the interior of the bowl and having in the present instance depend ing downwardly therefrom through a suit able aperture 4: in the base of the pipe a spindle 5, which stem extends beyond the under side of the pipe and has attached thereto in a suitable manner a handle 6, said handle in the present instance being in the form of a cross, the arms of which extend substantially across the base of the bowl.

The operation of the device will be apparent. hen it is desired to clean out the contents of the bowl, it is merely necessary to turn the handle 6 to cause rotation in the base of the bowl of the cleaning element 3,'the arms 8 and 3 of which element are thereby made to move over and to scrape the bottom and sides of the interior of the bowl, loosening any deposit of tobacco in the base of the bowl. The arms of the cleaning element may, of course, vary in number, and are preferably made thin so as to lie flat against the sides of the bowl. The said arms furthermore may extend upwardly in the bowl to any desired height, even to the extreme top of the bowl if this is found desirable, but it is preferred to extend these arms upwardly only to an extent substantially as illustrated in the draw ings, so that the upper portion of the bowl of the pipe, which is comparatively easy to clean and which does not ordinarily accumulate the sodden tobacco masses found in the bottom of the bowl, may undergo the well known caking process in which a hard deposit is formed upon the walls of the bowl commonly supposed to give the pipe a good flavor.

It will be understood that although I have shown and described the stem 4 extending through the bottom of the pipe, this being the preferred form, it is possible to extend the stem through the side of the bowl, in the manner, for example, illustrated in Fig. 4. In this modification, the stem 7 is attached to the top of one of the upwardly extending arms of the cleaning element 8 which is semicircular in form to conform to the also semicircular contour of the bottom of the bowl. The stem 7 has a suitable arm or knob 9 at the outer end by means of which the stem is oscillated with the result that the element 8 is given an oscillatory movement around the upper end of the arms thereof as a pivot. Other modifications are possible with no departure from the essential features of the invention.

I do not desire to limit myself to any particular form of knob or handle for actuating the cleaning element, since this can be of any form desired and may for example, as shown in Fig. (3, be in the form of an extension 10 of the bowl of the pipe whereby except for the dividing line between the knob and the bowl proper, there will be no indication that a mechanical device of the nature described is mounted in the pipe.

I claim:

A pipe comprising a bowl, a stem extending from the bowl, a cleaning element movably mounted in the bowl, 21 shaft secured to said element and extending through an aperture in the bottom of the bowl, and an operating element for the cleaner secured to said shaft on the under side of 10 the bowl and shaped to appear as a continuation 0f the latter.

BOLTON L. CORSON.
