SMOKING PIPE Filed March 25, 1936 BY mw ATTORNEY Panarea Mar. 2, 1937 UNITED sTATEs PATENT OFFICE SMOKING PIPE Allen H.l Rogers, York Village, Maine Application March 23, 1936, Serial No. 70,496

3 Claims.

This invention relates to smoking pipes, and its general object is to provide a pipe in which the smoke passages thereof can be retained open, as all matter accumulating therein and tending to clog the same can be easily and expeditiously removed therefrom, without necessitating the removal or separation of the parts of the pipe from each other.

A further object of the invention is to provide a pipe of the straight type, that is self-supporting in an upright position, and is constructed to prevent saliva or liquid from returning to the mouth of the user.

Another object of the invention is to provide i5 a pipe of the character set forth, that is simple in construction, inexpensive to manufacture and extremely eicient in use and service.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims, g

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a top plan view ofthe pipe which forms the subject matter of the present invention.

Figure 2 is a sectional view taken approximately on line 2-2 of Figure l, looking in the direction of the arrows.

Figure 3 is a detail view illustrating the draft tube and the. scraping or cleaning means that is housed therein.

Referring to the drawing in detail, the reference numeral l indicates the bowl of my pipe which as shown is of cylindrical conguration and includes a flat bottom 2, with the result it will be seen that the pipe is self-supporting in an upright position, as indicated in Figure 2. The bowl is provided with a vertical recess 3 disposed at the rear thereof and which communicates with the bore of the bowl, in the form as shown. Formed on and extending rearwardly from the bowl at the upper end thereof is an extension a that has tapered side walls merging into the bowl, as best shown in Figure 1. The extension 4 provides the stem for the pipe and has a bore therein extending horizontally thereof for communica- I tion with the recess 3.

Mounted in the bore of the stem is a tube 5 of a length to extend to the recess 3 at one end and its opposite end portion projects beyond the stem to be received in a bore formed in one end of a mouth piece 5, the tube fitting the bore to frictionally secure the mouth piece to the stem and the mouth piece is further provided with a smoke passage communicating with the tube, as shown in Figure 2.

vIt will be noted that when the mouth piece is frictionally secured to the tube 5 it is disposed iiush with the outer end of the stem for alignment therewith, and as the stem or extension d i is disposed above the bottom of the bore of the bowl, it will be impossible for saliva or liquid t0 return to the mouth of the user.

Removably mounted in the recess is what I term a draft tube 1 which is of a length to terminate above the bottom of the recess which has its lower end communicating with the bore of the bowl, and the upper end of the draft tube is closed as at 8 but has an opening therein for the passage of the reduced upper end portion 9 lof a cleaning pin I0 mounted for movement within the tube 1 and which is of a length to contact the bottom of the recess. The thick or major portion of the pin lll is curved, to contact the wall of the tube l, for removing matter that may accumulate thereon, and it will be obvious that the matter is removed by rotating the pin, while the lower end of the pin is used to remove matter that accumulates in the bottom of the recess, as well as inthe lower portion of the tube l, thelatter being accomplished by moving the pin up and down. When the matter is removed from the wall of the tube 'l and the recess 3, it can be easily blown into the bowl, as well as from the latter. 'I'he upper end of the tube 1 is disposed iiush with the top of the bowland the upperl end of the pin is bent upon itself to provide a handle Il. The tube 1 is preferably held within the recess through the instrumentality of a pin I2 that is disposed transversely of the bowl and contacts the tube l, as clearly shown in Figure 2.

vArranged in the tube adjacent the upper end thereof is a slot I3 that registers with the inner end of the tube 5, so that a complete smoke passage is provided between the bottom of the bowl and the outer end of the mouth piece. The tube l not only acts as a housing for the cleaning pin l0, but likewise provides a draft means, to enable a better drawing action in the event the bowl of the pipe is packed tight with tobacco, with the result it will be seen that my pipe has many advantages over pipes now in general use, and one of the important advantages is the fact that the mouth piece does not have to be removed from the stem, to scrape and remove matter that. f

Cil

accumulates in the smoke passage adjacent to and at its point of communication with the bowl.

It is thought from the foregoing ldescription that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changesv fall within the scope of the appended claims.

What I claim is: l. A pipe comprising a bowl, a tube mounted in the bowl and spaced from the lower end thereof for communication with the bore of the bowl, a stem extending at an angle from the upper end of `the bowl and having a passage communicating with the tube adjacent the upper end of the latter, a mouth piece secured to the stem and means within the tube and mounted for movement therein to remove matter accumulating on the walls thereof.

2. A pipe comprising a bowl having a recess arranged in the rear of the bore thereof. a tube having a closed upper end and an open lower end, the latter being spaced from the bottom of the recess and communicating with the bore of the bowl, a stem extending from the upper end of the bowl, a tube in said stem and having one end amarre and a handle for the means and formed. on thel extending portion thereof.

3. A. pipe comprising a bowl, a vertically arranged tube secured in the bore of the bowl at the rear portion thereof and having an open lower end communicating with the bore, a stem formed on the bowl at the upper end thereof, a tube extending through the stem and having one end communicating with the tube rst mentioned adjacent the upper end thereof, a mouth piece frictionally mounted on the second tube to be secured to the stem, a cleaning pin mounted for movement in the lrst tube and extending above the upper end thereof, said extending portion of the pin being bent upon itself to provide a handle, said pin being curved to contact the walls of the rst tube to remove matter therefrom, and the lower end of the pin being engageable with the bottom of the bore.
