' 'roiaacco PIPE.

Application filed October 25, 1927. Serial No. 228,564.

This invention relates to a tobacco pipe such as shown in my prior Patent No. 1,433,- 228 of October 24, 1922, and the objects of the present improvementsv are to provide means for facilitating the removal of the plug at the bottom of the bowl; to provide for that purpose a'rotary cam; to provide for said cam an operating arm or handle which normally lies lengthwise of the stem of the pipe and locks thereagainst; to utilize said arm or handle in the formation of a supporting base for the pipe which shall hold the mouthpiece end of the stem elevated at an angle, and to obtain other advantages and results as may be brought outby the following description.

Referring to the accompanying drawings, in which like characters of reference indicate the same parts throughout the several views,

Figure 1 is a vertical longitudinal sectional view through a tobacco pipe embodying my invention;

Figure 2 is a transverse vertical sectional viewthrough the bowl thereof, taken on the line 22 of Fig. 1;

Figure 3 is a transverse sectional view through the'stem of the bowl, taken on the line 33 of Fig. 1;

. Figure 4 is a plan view of the pipe, looking down into the bowl; Figure 5 is an underneath view, looking at the closed bottom of the bowl, and showing in dotted lines the plug removing cam turned into ejecting'position; I

Figure 6 is a plan view, looking down into the bowl with the cam in ejecting position and the plug removed, and r Figure? is a detail perspective view of the cam and its bushing.

In said drawings, the reference character -1 designates the bowl of a pipe which is formed with the usual laterally projecting stem 2 which is provided with an axial opening 3; A cylindrical plug4 formed of nonabsorbent material is mounted in an opening 5 transverse of the bottom of the bowl 1 and in alinementwit-h the passage 3 of the stem of the'bowl, said plug being provided with a finger piece or head 6 for removing the same from the opening The plug 4 is formed with an axial smoke passage 7 and has one side thereof cut away as at 8 to form communication bet-ween the passage 7 and the bowl of the pipe, as shown in Figures 1 and 2. The inner end of the plug is formed with a reduced axial extension 9 the tube 13 into the mouthpiece. end of the plug 4 is preferably formed which projects into the passage 3, and the said passage is formed with an annular shoulder 10 to limit the insertion of the plug 4 into the passage 3.

The mouthpiece 11 of the pipe is removably fitted into the end of the stem 2 of the bowl, and is formed with a bore 12 adapted to removably receive a tube 13 which projects from the end of the stem and is adapted to frictionally fitover the reduced extension 9 of the plug 4, as shown in Figure 1, when the mouthpiece 11 mm position in the pipe. The bore 12 is provided at its outer end with a shoulder 14 which limits the insertion of The inner inwardly of the extension 9 with a tapered portion 15 onto which the end of the tube 13 is slipped so as to form a tight connection between the tube 13 and theplug 4.

WVith this construction, as set forth in my prior patent above referred to, the nonenough so that to remove the tube 13 it is merely necessary to take outfthe plug 4,

bringing the tube 13 with it out of the bore sometimes'happens, when this is done, that i the plug sticks and cannot be easily and readily remoVecLand by the present invention I provide means for overcoming. this difficulty; The plug is provided at its underside with a'shoulder 16 whichI have shown formed by cutting away or flattening the under surface of the plug for its inner endportion, as 'at'17. A cam 18 is mounted in the bottom wall of the bowl having an eccentric'upper portion 19 to engage said shoulder 16 and force the plug out-far enough to loosen it, and a middle cylindrical portion 20 of said cam is mounted in a bushing 21 inserted in the bottom of the bowl.

The cam further has a reduced diametric flattened lower end 22 which projects atthe base 23 of the pipe bowl and receives an arm or handle 2- which is riveted on said end 22 so that when the cam is in idle position said arm or handle extends therefrom longitudinally of the. pipe stem toward the mouthpiece 11 of the pipe. -The free end of said arm is bent upward to bear with spring pressure against the bottom of the stem 2, and is transversely concaved to fit thereagainst and prevent inadvertent lateral movement. Also, preferably, said end of the arm is bifurcated and the branches 25,

' curled backwardly downward each upon itself to form feet which will enable the pipe to stand up with its mouthpiece elevated at an angle to the supporting surface, as shown in Figure 1. These curled

bifurcations

25, 25 also provide linger holds forpressing the arm or handle 2% sideways out of engagementwith the stem 2 in order to turn it and operate the cam 18 to remove the plug 4, as shown in dotted lines in Figure 5 and full lines in Figure 6.

liurthermore, the upper surface or top of the eccentric upper portion 19 of the cam 18 preferably is beveled so that when the cam is inidle position as shown in Figure 1 it forces the plug e upward into tightened engagement with the upper part of its opening 5, but when the cam is turned to eject the plug 4 it exerts no upward pressure upon the plug. This is accomplished by beveling the top of the cam from its edge which overlies the arm or handle 2a to its opposite edge, as at 26, and beveling the flattened under surface of plug 4: adjacent its shoulder 1.6 in the opposite direction, as shown at 27 in Figure 1.

After the cam 18 has ejected or loosened the plug 4 by turning itshandle into the position shown in dotted lines in Figure 5, it is swung back halfway to its initial position, so that it will not interfere with reinserting the plug a. An additional fea ture of my present invention is that the flattened lower surface of the plug 4; contacts with the top of the cam when the plug is reinserted and prevents the plug from being put in'turned or rotated a. little out of its proper position.

Various detail modifications may be made in manufacturing my invention, by those skilled in the art, without departing from the spirit and scope of the invention, and therefore I do not wish to be understood as limiting myself except as required by the following claims when construed in the light of the prior art.

Having thus what I claim is:

1.. In a tobacco pipe, the combination with a. bowl having a stemand an opening arranged transversely of the bottom said described the invention,

bowl. and leading to said stem, of a plug removably mounted in said openingin the bowl and having a passage communicating with said bowl and said stem, and means at the bottom of the bowl beneath said plug for ejecting it. V
