Patented Oct. 29, 1935 UNITED STATES PATENT OFFICE TOBACCO PIPE John C. McMackin, Ridgway, Pa. Application May 3, 1935, Serial No. 19,715 4 Claims. (Cl. 131-12) The present invention relates to new and useful improvements in tobacco pipes and has for its primary object to provide, in a manner as hereinafter set forth, a pipe comprising a novel I construction through the medium of which said pipe may be expeditiously and thoroughly cleaned, thus promoting sanitation as well as adding Inaterially to the enjoyment of smoking.

Other objects of the invention are to provide l a tobacco pipe of the aforementioned character which will be comparatively simple in construction, strong, durable, compact, light in weight, attractive in appearance, economical in the use of tobacco and which may be manufactured at 16 low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawing, wherein like characters of reference designate corresponding parts throughout the several views, and wherein:-

Figure 1 is a view partially in side elevation and partially in vertical longitudinal section of a tobacco pipe embodying the present invention.

Figure 2 is an elevational View, looking at the outer end of the pipe.

Figure 3 is a view in vertical longitudinal section through a modification.

Referring now to the drawing in detail, it will be seen that the reference numeral I designates the bowl of the pipe from the lower portion of which a stem 2 projects. The stem 2, of course, is provided with a bore 3. Mounted on the stem 2 is a mouthpiece 4 to which is connected a tube 5 which extends through the bore 3 of the stem 2 and traverses the lower portion of the bowl I, as illustrated to advantage in Figure 1 of the drawing.

In the lower portion of its front, the bowl I has formed therein a clean-out opening 6 which is aligned with the bore 3. Mounted in the opening 6 is a. sleeve 'I into which the forward end portion of the tube 5 extends in spaced, concentric relation to said sleeve. Adjacent its forward end, the tube 5 has formed thereon a substantially conical shoulder or enlargement 8 which seats in the inner end of the sleeve 'I in a manner to substantially constitute a valve. The tube 5 is provided with an opening 9 for communication with the bowl I.

The tube 5 is closed at its forward end through the medium of a cap IQ which is adapted to slip between said tube 5 and the sleeve l. The closed end of the cap I0 includes a flange II engageable with the outer end of the sleeve 1. The cap I0 further includes a guide pin or plug I2 which is engageable in the tube 5.

It will thus be seen that the construction and arrangement are such that saliva will not enter 5 the bowl I and saturate the tobacco in the lower portion of said bowl. By removing the cap I0 and blowing through the stem, saliva and sediment that may accumulate in the tube 5 may be conveniently ejected. Also the construction and arl0 rangement are such that a cleaner may be conveniently passed entirely through the stem. The tapered portion or cone 3 centers the forward end of the tube 5 in the sleeve l.

It will be observed that the tube 5 is spaced l5 from the bore 3, thus permitting withdrawal of said tube with the enlargement 8 thereon with the mouthpiece 4. By locating the opening 9 within the stem 2 in spaced relation to the bowl I, as shown in Figure l of the drawing, clogging 20 of said opening 9 will be prevented.

In the modification shown in Figure 3 of the drawing, the tube 5 terminates in a rounded or blunt forward end portion I3 immediately adjacent which is a fixed ring I4. The ring I4 is 25 engageable in the sleeve 'I and has formed on its inner or rear end an external flange I5. A cap I6 is adapted to be removably mounted on the ring I4 with its inner end in abutting engagement with the flange I5. It will be noted that 30 when the cap I6 is in engagement with the flange I5, the closed outer end of said cap will be spaced from the corresponding end of the tube 5 and in this manner a chamber is provided for the reception of saliva, sediment, etc. 35

It is believed that the many advantages of a tobacco pipe constructed in accordance with the present invention will be readily understood, and although preferred embodiments of the device are as illustrated and described, it is to be understood that further modifications and changes in the details of construction may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:- 45

1. A tobacco pipe comprising a bowl, a stem projecting from said bowl, said stem having a bore therein, the bowl having a clean-out opening therein aligned with the bore, a mouthpiece mounted on the stem, a tube mounted on the 50 mouthpiece and extending therefrom through the stem and through the lower portion of the bowl into the clean-out opening, said tube having an opening therein communicating with the bowl, an enlargement on the forward end portion of 66 the tube engageable in the clean-out opening, and a cap removably mounted on the forward end portion of the tube.

2. A tobacco pipe comprising a bowl, a stem projecting from said bowl, said stem having a longitudinal bore therein, lthe bowl having a clean-out opening therein aligned with the bore, a mouthpiece mounted on the Stem, a sleeve mounted in the clean-out opening, a tube mounted on the mouthpiece and extending therefrom through the stem and through the bowl into the sleeve, said tube having an opening therein communicating with the bowl, an enlargement on the tube adjacent the forward end thereof engageable with the inner end 0f the sleeve, and a removable cap mounted on the forward end portion of the tube, said cap including a flange on its closed end engageable with the outer end of the sleeve.

3. A tobacco pipe comprising a bowl, a stem projecting from said bowl, said stem having a longitudinal bore therein, the bowl having a clean-out passage therein aligned with the bore, a sleeve mounted in the clean-out opening, a mouthpiece mounted on the stem, a tube mounted on the mouthpiece and extending therefrom through the stem and through the bowl into the Y sleeve, said tube being spaced concentrically with tube, said cap being engageable between said tube and sleeve, said cap including a guide plug engageable'in the tube and further including a iiange on its outer end engageable with the outer end of the sleeve.

4. A tobacco pipe comprising a bowl, a stem projecting from said bowl having a longitudinal bore therein, the bowl having a clean-out opening therein aligned with the bore, a mouthpiece mounted on the stem, a tube mounted on the mouthpiece and extending therefrom through the stem and through the bowl into the clean-out opening, a ring xed on the forward end portion of the tube and engageable in the clean-out opening, an external iiange on the rear end of said ring, and a cap for the forward end of the tube mounted on the ring in abutting engagement with the flange.
