SMOKING PIPE Filed Oct. 11, 1939 4 iv Q 2 lNVENTbR rrwsssss I Patented Nov. 12, 1940 SMQKING Pmn John Lang, New York, N. Y. Application ()ctober 11, 1939. Serial No. waste 1 Claim. (o1. 131 181) This invention relates to an improved smoking pipe and has for an object to provide a construction wherein means are provided for urging the tobacco toward the fire.

Another object of the invention is to provide a smoking pipe wherein the bowl of the pipe is loaded at the usual end and means provided which will continually urge the tobacco toward the loading or entrance end so that the tobacco is moved toward the fire instead of the fire toward the tobacco.

An additional and more specific object is to provide a pipe having a tobacco chamber and springactuated means for urging the tobacco toward the entrance end of the bowl so that during the smoking operation the tobacco will be gradually moved toward the fire whereby a minimum amount of ashes falls to the bottom of the pipe bowl.

In the accompanying drawing Fig. 1 illustrates a pipe embodying the invention, the bowl portion being shown in vertical section;

Fig. 2 is a longitudinal vertical section through a slightly modified form of pipe to that shown in 5 Fig. 1;

Fig. 8 is a sectional view through the cap or entrance end member shown in Fig. 2;

Fig. 4 is a front view of the structure shown in Fig. 3.

Referring to the accompanying drawing by numerals, i indicates the bowl of the pipe, which bowl merges into a stem 2 having a mouthpiece 3 of any usual or preferred structure. The smoking pipe may be made to represent a conventional pipe, as shown in Fig. 1, or may be made to represent a cigar or other smoking article, as shown in Fig. 2. It will, therefore, be understood that the expression smoking pipe will refer to both forms of the invention or any other embodiment thereof wherein the same principles are used.

As illustrated in Fig. 1, the bowl 5 is provided with a body i that has a closed end 5 merging into a stem 2. The parts just described may be made of briar root or other suitable material, but the entrance end member or portion 6 is made of substantially fire-proof material, as for instance, metal or meerschaum. The entrance end portion 6 is provided with a threaded part i screwed into the ofiset threaded part 8 of the body l. The

5 member 6 is provided with an annular inturned flange portion 9 which results in the formation of an entrance end opening i0 through which the tobacco is inserted into the chamber l i. As shown in Fig. l, the tobacco i2 completely fills 55 the chamber H and extends from the entrance opening it to the follower plate is. This plate may be of any foraminous material, as for instance, it may be a perforated metal plate having an annular depressed portion i i and a flange portion it, which flange portion is provided with 5 an annular bevel it. The end of the bevel is very near the side wall of the chamber H but as the tobacco is consumed the coil spring i! forces the plate it upwardly or toward the entrance end it and as the plate it moves it will allow small 10 particles of the tobacco or ashes to pass. The coil spring ll has one end or end portion resting on the bottom it of the tubular socket l9 while the other end surrounds the depressed portion i l. The spring El is preferably formed suiliciently 35 strong to push the plate It and the tobacco upwardly as fast as the tobacco is consumed at the entrance end it. Also preferably the spring it is sufficiently long to force plate it up to within a short distance of the entrance end of the pipe. 20

By this construction and arrangement the tobacco moves toward the zone of fire rather than the zone of fire moving toward the tobacco. This has a tendency to keep the bottom part of the chamber clean of saliva and other deposit. Any 25 ashes or tobacco falling down past the beveled edge it may be readily removed by turning the pipe upside down and strilc ng the same against an object. If desired, the end member 6 maybe unscrewed and plate it removed for a thorough 30 cleaning. The parts may then be replaced and after this has been done tobacco may be forced in through the end member it. As the tobacco is forced into the chamber ii, the plate it begins to move downwardly toward the closed end 5 until 35 the parts assume the position shown in Fig. 1 when the bowl is completely filled.

In the structure shown in Fig. 2, the smoking pipe is formed in the shape of a cigar and the detail structure is slightly different though the principle is the same. In this form of the invention the body i has an interiorly threaded end 26 and a tapering tubular member 29' for receiving the tobacco The end toward the mouthpiece 22 is preferably straight and accommodates the coil spring it, whereby the plate l3 may be properly actuated. Between the tapering tubular member 2i and the body Hi there is a hollow space 23 which prevents the heat from undesirably heating the body l. A removable cap M is provided, said cap being formed of any desired material, as for instance, briar root, metal or. meerschaum. The cap 2t is provided with a threaded portion 25 adapted to be screwed into the threaded portion 29. Also cap 2 5 is provided with an annular interiorly extending flange 26 against which the foraminous member or wire mesh 21 fits. The'mouthpiece 22 is screwed on to one end of the body l, while the cap 24 is screwed into the opposite end. When the parts are in the posititon shown in Fig. 2, the tobacco may be lighted and during the smoking operation spring I? will gradually force plate I3 toward the wire mesh 27.

After the tobacco has been burned and it is desired to re-light the pipe, preferably the cap 24 is removed and a new supply forced into the position shown in Fig. 2 and then cap 24 replaced. It will be understood, of course, that it will not be necessary to completely fill the tobacco chamber unless desired.

I claim:

A smoking pipe including a bowl having an inturned entrance end and an outlet end provided with a tubular bore extending axially of the bowl and a smoke outlet passageway of less diameter than said bore leading from said bore intermediate its length, a tobacco chamber of greater diameter than said bore between said bore and said entrance end whereby a shoulder is provided at the juncture of said chamber and said bore, a follower plate in said chamber formed with a central perforated depressed part adapted to extend into said bore when said chamber is filled with tobacco and a radiating flange extending to near the wall of said chamber, said flange resting on said shoulder when said chamber is full of tobacco and a coil spring positioned with one end portion in said bore and the other end portion surrounding said central perforated depressed part of said plate, said spring urging said follower plate toward said entrance end to maintain the ignited portion of the tobacco adjacent said entrance end.
