Application February 2, 1945, Serial No. 575,777

4 Claims. (01.1 31-184) This invention relates to improvements in smoking pipes.

A primary object of the invention is to provide an improved smoking pipe wherein the stem of the pipe is longitudinally divided into sections normally maintained in assembled relationship but which can be separated so as to expose the passage through the stem throughout substantially its complete length to facilitate cleaning.

More specifically, an object of the invention is to provide a smoking pipe consisting of a bowl and a stem, the stem being longitudinally divided opposite the passage ther-ethrough into sections, one of which is integral with or attached to the bowl, and the other of which has a dovetail end groove connection with the mentioned section which will enable the other section to be caused to slide longitudinally relatively to the bowl and its attached stem section, to thus divide the stem and expose the passage therethrough for cleaning.

Another object of the invention is to provide a smoking pipe having the above mentioned characteristics wherein one-of the sections is provided with a pin that extends into the passage through the stem so that when the sections are caused to slide relatively to each other to separate them the pin will automatically be drawn through the passage through the stem to largely clean it.

. With the foregoing and other objects in view which will be made manifest in the following detailed description and specifically pointed out in the appended claims, reference is had to the accompanying drawings for an illustrative embodiment of the invention, wherein:

Fig. 1 is a top plan view of the improved smoking pipe.

Fig. 2 is a view in side elevation of the same.

Fig. 3 is a longitudinal vertical section taken substantially upon the line 3--3 upon Fig. 1.

Fig. 4 is an enlarged vertical section through the bowl portion of the pipe.

Fig. 5 is a Vertical section taken substantially upon the line 5-5 upon Fig. 3.

Referring to the accompanying drawings wherein similar reference characters designate similar parts throughout, the improved smoking pipe comprises a bowl l0 having a stem ll through which extends a longitudinal passage l2, 2. small inclined bore l3 which connects the bottom of the bowl with the forward end of passage T2. In the preferred form of construction the body of the pipe is formed of a synthetic resin plastic but it may be formed of any suitable material. The bowl is preferably lined as at H with a meershaum lining or the equivalent. Thelming 14 preferably has an outwardly extending flange at its top overlying the top of the bowl oi the pipe to act as a protector. This is or particular-advantage when the :body of the pipe is formed of a synthetic resin plastic. The stem H is 1011i gitu-dinally divided into two sections, the upper section being indicated at 15, which is permanent- 1y attached to or integral with the bowl 10. The lower section indicated at l5 has a forward nortlon i1 integral therewith which forms the loottom of the body of the bowl 1-0 and fits around the bottom of the meershaum lining H. The mutually engagealole surfaces between the portion I! and the loottom of the body of the bowl form an abutment limiting rearward sliding movement 'of the lower section relative "to the upper section. The lower section has a groove 18 formed on its upper surface which provides the passage [2 leading from the bore 43 to the bit 19. Above groove the lower section is formed with a dove-tail groove 2-0 adapted to receive the dovetail 2| on the bottom of the upper section 15. The groove *8 extends forwardly a short distance beyond the hole of bore l3. 2-2 indicates :a pin that is attached to or formed integral with the upper section 15 and which extends downwardly into the roove 18 at its forward end.

In the use of the smoking pipe thebowl may he filled a conventional manner and the smoke drawn to the bit 19 through the bore 18 and the passage 12. Whenever it is desired to clean the passage 12 the lower section Iii may be caused to slid-e forwardly relative to the upper section 15 and the bowl l0, and the two sections of the stem can thus be completely separated from each other. This exposes the top of groove l8 so that this groove may be readily cleaned. As the lower section I6 is caused to slide forwardly, the pin .22 will pass rearwardly through the groove removing dirt therefrom to a large extent. This dirt may be readily rinsed ofi or otherwise re moved from the pin and any remainin dirt in the exposed groove 18 can be readily cleaned in any preferred manner. When the pipe has thus been cleaned, the sections may again be bled together by sliding the lower section It rearswardly on the dove-tail on the upper section until portion l'l engages the upper portion of the bowl limiting rearward movement. The pipe, as thus reassembled, is then ready for continued use.

From the above described construction it will be appreciated that the improved pipe is of :relatively simple and highly durable construction and that the stem is readily separable longitudinally into sections, which, when they are separated, will expose the passage 12 throughout substantially its complete length to facilitate cleaning. It will, of course, be appreciated that if any filtering device is inserted in the passage 12 between the ends thereof, that such filtering device may be removed with the lower section [6 and easily cleaned.

Various changes may be made in the details of construction without departing from the spirit or scope of the invention as defined by the appended claims.

I claim:

1. A smoking pipe comprising an upper part and a lower part, the upper part including an upper stem section and an upper bowl section integral with one another, the lower part of the pipe including a lower stem section and a lower bowl section integral with one another, a dovetail on one stem section and a dovetailed groove to receive the dovetail on the other stem section enabling .one part of the pipe to slide relative to the other part of the pipe to separate or assemble the parts of the pipe, the bowl sections being parted along a line extending generally upwardly from the parting line of the stem sections so that the lower bowl section contacts the upper bowl section preventing further forward movement of the lower part of the pipe relative to the upper part of the pipe, the lower stem section having a substantially straight groove of substantially uniform cross section throughout its length along the face thereof exposed at the parting line of the stem sections and forming a smoke-conveying passageway, the upper part of the pipe providing a bore interconnecting the well in the bowl with said smoke-conveying passageway, the smokeconveying passageway extending beyond the bore, and a pin integral with the upper part of the pipe and located behind the bore and extending from the upper part of the pipe into the extended portion of the smoke-conveying passageway and completely filling the passageway, whereby when the lower part of the pipe is slid rearwardly with respect to the upper part of the pipe, the pin wipes the smoke-conveying passageway substantially from end to end, the smoke-conveying passageway being unobstructed from the bore to the outlet at the end of the stem.

2. A smoking pipe comprising an upper part and a lower part, the upper part including an upper stern section and an upper bowl section integral with one another, the lower part including a lower stem section and a lower bowl section integral with one another, a dovetail on one stem section and a dovetailed groove to receive the dovetail on the other stem section enabling one part of the pipe to slide relative to the other part of the pipe to separate or assemble the parts of the pipe, the bowl sections being parted along a line extending generally upwardly from the parting line of the stem sections so that the lower bowl section contacts the upper bowl section preventing further forward movement of the lower part of the pipe relative to the upper part of the pipe, the lower stem section having a substantially straight groove along the face thereof exposed at the parting line of the stem sections and forming a smoke-conveying passageway, the upper part of the pipe providing a bore interconnecting the well in the bowl with the smokeconveying passageway, the smoke-conveying passageway extending beyond the bore, and a pin located behind the bore and extending from the upper part of the pipe into the extended portion of the smoke-conveying passageway whereby when the lower part of the pipe is slid rearwardly with respect to the upper part of the pipe, the pin wipes the smoke-conveying passageway substantially from end to end.
