PIPE

Filed Nov. 16, 1937 ATTORNEYS Patented Apr. 11, 1939 PATENT OFFECE 2,153,955 PIPE Henry 0. Choquette, Three Rivers, Quebec, Canada Application November 16, 1937, Serial No. 174,874

4 Claims.

This invention relates to pipes, more particularly to a smoking pipe of wood or other material, and has for an object to provide a pipe of this character which will receive its entire draft from the bottom or sides at the bottom to provide a cool smoke and promote better combustion of the tobacco.

A further object is to provide a pipe the outer bowl or sleeve of which is open at the bottom and at the top, there being a cover interchangeably received on the bottom of the sleeve for lighting the pipe and upon the top of the sleeve and open top of the bowl for smoking the pipe and prevent smoke and glowing cinders escaping upwardly from the bowl.

A further object is to provide a device of this character which will be formed of a few strong simple and durable parts, which will be inexpensive to manufacture, and which will not easily get out of order.

With the above and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawing forming part of this specification,

Figure 1 is a side elevation of a pipe constructed in accordance with the invention.

Figure 2 is a bottom plan View of the pipe shown in Figure 1.

Figure 3 is a fragmentary top plan view of the pipe with the cover removed.

Figure 4 is a fragmentary longitudinal sectional view of the pipe taken on the line 4-4 of Figure 2.

Figure 5 is a rear elevation of the sleeve which fits in the bowl and showing the hollow lug which receives the front end of the stem of the pipe.

Figure 6 is a cross sectional view of the sleeve taken on the line 6-% of Figure 5.

Figure '7 is a bottom plan view of the cover.

Referring now to the drawing in which like characters of reference designate similar parts in the various views, ll! designates the sleeve of the pipe, which may be formed of wood or other material and which is fully open at the top and at the bottom, as best shown in Figure 4. The sleeve is provided at the upper end with an inner annular shoulder II. The bowl E2 of the pipe, preferably formed of clay composition, is provided near its upper end with an outer annular flange l3 which contacts with the underside of theshoulder Ii. The bowl is provided immediately below this flange with an annular series of inlet openings l6.

The bowl is closed at the bottom and is provided at its lower end with diametrically opposite lugs I5 and it, best shown in Figures 4 and 6, which contact with the inner wall of the sleeve, the lug It being hollow and communicating with the interior of the bowl.

The stem I? is provided with a stepped reduced front end H! which projects through an opening in the sleeve and extends into the hollow lug l6, as best shown in Figure 4 and holds the bowl within the sleeve.

A cover l9 preferably formed of wood or other material is interchangeably received on the open bottom of the sleeve 10 and upon the open top of the sleeve and bowl. For mounting the coverin place a hook-like flange 20 is formed on the bottom face of the cover, as best shown in Figures 4 and 7, the flange being interrupted at preferably three points by notches 2 l best shown in Figure '7, which interchangeably receive lugs 22 formed on the bottom of the sleeve, as best shown in Figure 1, or lugs 23 on the top of the sleeve, as best shown in Figure 4. When either set of lugs are passed into the notches 2| a slight turn of the cover secures the cover to the sleeve in either of its operative positions.

In operation, in order to light the pipe the cover 19 is disposed upon the bottom of the sleeve l0. While smoking the cover is placed at the top of the sleeve in and bowl l2. When the pipe is being smoked the draft enters the open bottom of the sleeve and passes up along the outside wall of the bowl l2 and enters the bowl through the openings I 4. The draft thus cools the bowl. Furthermore, any smoke and glowing cinders cannot escape upwardly from the top of the bowl due to the cover I9. Smoke emerging into the openings M will be entrapped in the space between the bowl and the sleeve, this space being annular and having a dished outer wall 24, as best shown in Figure 4.

From the above description it is thought that the construction and operation of the invention will be fully understood without further explanation.

What is claimed is:

l. A pipe comprising a sleeve fully open at the top and at the bottom, an inner annular shoulder projecting from the upper edge of the sleeve, a bowl provided near its upper end with an annular flange bearing against the underside of said shoulder, there being a plurality of openings in the bowl below said flange, the bowl being closed at the bottom and having its top substantially flush with the top of the sleeve, a stem projecting through the sleeve and entering the bowl near the bottom thereof, and a cover interchangeably received on the bottom of the sleeve and on the top of the sleeve and bowl.

2. A pipe including a sleeve fully open at the top and at the bottom, the sleeve being provided at the upper end with an inner annular shoulder, a bowl provided near its upper end with an annular flange bearing against the underside of said shoulder, there being inlet openings in the bowl below said flange, the bowl being closed at the bottom, diametrically opposed lugs projecting from the bowl and contacting with the inner wall of the sleeve, one of the lugs being hollow and communicating with the interior of the bowl, a stem provided with a stepped reduced front end projecting through an opening in the sleeve and extending into said hollow lug, and a cover interchangeably received on the open bottom of the sleeve and upon the open top of the sleeve and the bowl.

3. A pipe comprising a sleeve fully open at the top and at the bottom, a bowl within the sleeve and having its top substantially flush with the top of the sleeve, inlet openings in the bowl near the top thereof, means closing the space between the top of the sleeve and the top of the bowl for causing down draft in the bowl through said openings, a stem projecting through the sleeve and communicating with the bowl, lugs projecting from the bowl near the bottom thereof and engaging the inner wall of the sleeve, the inner wall of the sleeve above the lugs being dished and providing an annular smoke trap for smoke accidentally emerging through said openings in the bowl, and a cover interchangeably received on the bottom of the sleeve and on the top of the sleeve and top of the bowl.

4. A pipe including a sleeve fully open at the top and the bottom, a bowl disposed coaxial within the sleeve and closed at the bottom, diametrically opposed lugs projecting from the bowl and engaging the inner wall of the sleeve to space the major portion of the bowl from the sleeve and to removably secure the bowl in the sleeve, one of the lugs having an opening therein, a stem provided with a stepped reduced front end projecting through an opening in the sleeve and extending into said opening in the lug to secure the bowl in the sleeve, a cover received upon the open top of the sleeve and the bowl, and means at the top of the bowl and below the cover afl'ording communication between the interior of the bowl and the space between the bowl and the sleeve to permit updraft through the open bottom of the sleeve and downdraft through the bowl to the stem.
