UNITED STATES PATENT OFFICE SMOKING PIPE AND THE LIKE Elmer L. Schumacher and Lloyd W. Goddu, Southbridge, Mass.

This invention relates to improvements in tobacco smoking pipes and the like and has particular reference to improved cooling and condensing means therefor. Y

This application presents further improvements in the invention described in our prior application Serial Number 598,774 iiled in the United States Patent Oiiice on the 14th day of March 1932.

One of the principal objects of the invention is to provide cooling and condensing means of a simple and economical construction.

Another object of the invention is to provide cooling and condensing means that will be applicable to a pipe, cigarette holder, cigar holder, and other forms of tobacco smoking devices.

Another object of the invention is to provide improved means for Ventilating and cooling the internal cooling and condensing means.

Other objects of the invention are to provide simple and economical means for removing and cleaning the cooling and condensing means, for preventing internal moisture and condensation from engaging and expanding the bowl portion, for condensing and catching the moisture products in the smoke channel of the bowl portion, for making the bowl portion of pressed or molded construction aswell as turned or shaped, for providing a detachable bowl, and for providing means whereby various types of material and various colors of parts may be utilized to enhance the beauty and appearance of the device.

Other objects and advantages of the invention will become apparent from the following description taken in connection with the accompanying drawing. It will be apparent thatmany changes may be made in the details of construction and arrangement or parts Without departing from the spirit of the invention as expressed in the accompanying claims. We therefore do not wish to be limited to the exact arrangements shown and described, as the preferred forms have been shown and described by way of illustration only.

Referring to the drawing:

Figure I is a longitudinal section through a pipe embodying the invention.

Figure II is a longitudinal section through a pipe embodying a modied form of the invention.

Figure III is an end view of Figure II.

lFigure IV is a cross section on line IV-IV of Figure III, and,

Figure V is a longitudinal section through a cigarette or cigar holder embodying the invention.

In devices of this nature of prior art constructions the cooling and condensing means for cooling the smoke and condensing the moisture products in the draft cavity of the bowl portion have been bulky and of unsymmetrical shape, making them difficult and expensive of manufacture. It is, therefore, one of the principal objects of this invention to overcome these difculties and to provide simple, inexpensive and easily constructed means of symmetrical form for accomplishing these objects. The prior devices were also usually constructed to apply the specific device in which they were employed. Another object, therefore, of this invention is to provide means of this kind that are applicable to the various forms of smoking devices.

Referring to the drawing, wherein similar reference characters denote corresponding parts throughout:

In Figure I is shown the invention applied to a smoking pipe. The bowl 1, which may be made of wood or other desired material, has the tobacco cavity 2 and the draft opening 3 in the bottom thereof. The bowl 1 is provided with the threads 4, by which it is screwed into the stem portion 5 of the bowl. This stem portion 5 of the bowl may be made of wood or other material such as bakelite, hard rubber, or other compositions which may be moulded to shape if desired, and of any desired shading or coloring and of any applicable ornamentation. The part 5 has the bore 6 therethrough. The bore 6 is lined with the tube member 7 threaded at 8. Threaded into 8 is the plug member 9 having the central opening 10 into which is secured the cooling and condensing member 11. The member 11 is tubular in form and has the partion wall 12 intermediate its ends and the vent or port openings 13 adjacent the partition.

A smoke passage 14 is left between the liner 7 and the member 11, the vents or ports 13 opening thereinto. Both ends of the member 11 are open.

The stem 15, which may be of amber, bone, rubber, or other suitable material, has the usual mouthpiece 16 and draft channel 17, and is tted into the liner 7 at 18 by friction flt or a screw threaded connection or otherwise as desired, and in accordance with usual practice.

A tubular member 19 is tted into the channel 17 of the stem 15 at its bowl end, being a friction fit, screw threaded or otherwise secured therein. This member 19 has the central channel 20 extending longitudinally therethrough and communicating with the channel 17. The bowl end of 19 may be flared if desired as at 21. The

member 19 extends into the member 11 to apoint adjacent the partition 12, but leaving the space 22 open. The stem end of the member 11 is spaced from the bowl end of the stem 15, leaving the space 23. There is left a smoke space or channel 24 between the member 19 and the Vmember 11.

The draft opening 3 in the bowl 1 passes through the member 5 and the liner 7 and communicates with the smoke space or channel 14.

The operation is as follows: When the parts are assembled the smoke passage leads down from the bowl activity 2 through the opening 3 into the channel 14, bends around the stem end of the member 11 through the channel 24 between the member 11 and the member 19, around the bowl end of the member 19 into the channel 20 in 19, thence to the channel 17 in the stem to the mouth. In the meantime, air from the atmosphere is drawn into the channel 25 in the member 11, passes through the vents or ports 13 into the smoke channel 14, thus cooling the smoke stream. The atmospheric air in the channel 25 of the member 11 and in the smoke stream after it passes through the vents or ports 13, cools the member 11 and also the member 19. The members 11 and 19 are preferably of metal and this cooled metal causes the products of moisture in the smoke stream to condense and to be deposited on the walls of the members 11 and 19. Most o1' this condensation will eventually be drawn into the space 22, which acts as a catch bowl.

The member 11 may be removed for cleaning by unscrewing the member 9 from the threads at 18 and pulling out the member 11 when the condensation may be removed and the member 11 cleaned.

The device described has included theliner 7. If desired, this liner may be left out. Its use, however, will prevent moisture from contacting with the part 5 and causing it to swell if it is made of wood or other material affected by moisture. Where the part 5 is made of material not affected by moisture the liner 7 may well be dispensed with.

It will be noted that the cooling and condensing arrangements comprise but two simple metallic tubular members, the parts 11 and 19, cheap of construction and simple in assembly and operation, and generally adaptable to various forms of smoking devices. The passage of the smoke is so staggered that practically no impurities will reach the stem and mouth.

In Figure V the invention has been shown as applied to cigarette and cigar holders; the construction, arrangement of parts, and the opera- -tion is practically the same as that of Figure I. These holders are much smaller than the pipes and can be made up attractively in various materials and colors.

In Figures 1I and IV are shown arrangements by which additional cooling or Ventilating surface may be obtained. The construction in general is the same as that of Figure I except that a space or channel 26 is provided between the bowl part 5 and the liner 7, and through the part 5 is provided the Ventilating slots or openings 27, through which ratmospheric air may enter to cool the liner 7. Otherwise the construction and operation is the same as has been described for Figure I.

From the foregoing it will be seen that there has been provided simple, eiiicient, and economical arrangements for carrying out all of the objects of the invention and for obtaining its various advantages.
