3 Claims.
This invention relates to improvements in smoking pipes, and more particularly to that class of pipes containing in the stem a moisture trap for the collection of moisture, particles of tobacco, and saliva.
One object of my invention is to provide means by which the smokers act of emptying the contents of the bowl by the conventional act of inverting the pipe and knocking it against an object, results in the automatic drainage of the liquid collected in .the moisture trap.
It is also my purpose to provide novel and use metal extension shown in Fig. 2, taken along line 22 of Fig. 1. I
Fig. 4 is a cross sectional View of the stem taken along line 44 of Fig. l.
Fig. 5 is an end view of the bit with the eX- tension removed.
Like parts are identified by the same reference characters throughout the several views.
My improved pipe is of the type in which the 'bowl 6 is integral with a portion 1 of the stem from which the bit 8 is readily removable. The stem portion 1 has a trap, or central chamber 9, constituting an enlargement of its bore in. The bit has a terminal part II reduced in diameter to fit telescopically and rotatably into the enlarged. end of stem portion 1. stituting an extension of bore ill projects cen- Tube I3, constituting an extension of the bit bore 18 is offset at l4 to enter the trap chamberand project longitudinally of tube i2 at one side thereof, and normally along the top of the chamber. The terminus of tube 13 is preferably plugged at I5'and access to tube I3 is provided by one or more lateral openings at it. Tube l3 has a pressed fit in the bore of bit 8 and is positively secured against rotation respecting the bit by engagement in a notch ll formed in the terminal part ll ofthe bit to accommodate the offset M of tube [3, the sides of the notch constituting A tube 12 conmeans constraining the tube to rotate withthe bit.
The location of the end of tube l2 in the center of the trap prevents the return to the bowl of liquid collected in the trap. The disposition of openings l6 at the topof the trap normally prevents accumulated material from passing toward thebit. The concentric disposition of the terminus I5 of tube l3 with reference to tube I2 permits the said terminus to rotate with the bit about tube 1 when the bit is rotated in the stem as is a usual incident to its removal. The plugged terminus rotating in the trap adjacent the inner surface of the wall thereof assists in dislodging trapped accumulations and facilitates cleaning. The terminal portion of the tube is preferably flattened to conform to the wall of the chamber to facilitate its use as a scraper.
I claim:
1. In a pipe, the combination with a bowl, a stem provided with a duct communicating with the bowl, and a rotatab-ly mounted bit provided with a longitudinal duct in separable connection with said stem, said stem being provided with a central chamber, of a tube centrally projecting from said stem duct into said chamber, and a second tube projecting from the duct in said bit into said chamber in radially spaced and longitudinally overlapping relation to said first mentioned tube and having a portion contiguous to the wall of said chamber, whereby when the bit is rotated said second tube may serve as a scraper to clean the walls of said chamber preparatory to a separation of the bit and the stem.
2. A pipe including in combination a bowl and severable stem portions provided with central bores, one of said portions having an enlargement of its said bore to form a chamber of which one of said stem portions provides an outer wall, a tube projecting centrally into said chamber from the bore of the stem portion nearest the bowl, and a tube communicating with the bore of the other stem portion and projecting therefrom outwardly toward the chamber wall and thence longitudinally along said wall between said wall and said first mentioned tube, said last mentioned tube having a plug at its terminus and a lateral opening through its side. i
3. A pipe including a bowl, a first stem portion connected with the bowl and provided with a bore communicating therewith, a second stem I which its bore opens, said first and second stem second stem portion into said chamber and obliquely offset to clear said first mentioned tube and thence extending longitudinally beside said first mentioned tube to rotate about said first mentioned tube in the course of relative rotation between said stem portions, said second mentioned stem portion having a notch lateral- 1y communicating with its bore and in which a part of the ofiset portion'of saidtube is engaged, whereby to key said second tube to said stem bit portion to rotate therewith and to constitute a scraper for cleansing said chamber.
