2 Claims.

This invention relates to smoking pipes. It is particularly directed to a water cooled smoking pipe. 7

An object of this invention is to provide a highly improved smoking pipe of the character described comprising a stem to which the bowl is attached and a bit fitted within the rear end of the stem, said stem extending forwardly beyond the bowl, and being provided with a chamber into which cooling liquid may be inserted through the front or near end of the stem, and the opening through which the water is inserted being closed by a removable cap.

Another object of this invention is to provide in a smoking pipe of the character described, a stem having a smoke passage passing through the water chamber and connected to the top of the stem by a fin which acts to dispel heat, the

smoke passage being otherwise surrounded by cooling liquid in the chamber which also serves to cool the smoke going through the passage.

Still another object of this invention is to provide in a smoking pipe of the character described, a stem provided with a liquid chamber which has only one opening, the stem having an inlet opening for inserting cooling liquid into said chamber, said opening being closed by a screw cap, the arrangement being such, furthermore, that when the screw cap is removed for inserting liquid into the liquid chamber, the smoke passage is not disturbed, that is, the opening for the liquid chamber is separate and apart from the smoke passage.

Yet another object of this invention is to provide in a smoking pipe of the character described, a stem which may be readily manufactured as a single metal die casting, and includes a smoke passage, a liquid chamber surrounding said smoke passage, a filter chamber at one end of the smoke passage and communicating therewith, a cooling fin connecting said smoke passage with the top wall of the stem, a seat for the pipe bowl, a passage extending from the smoke passage to the pipe bowl, an opening for the cap which closes the liquid chamber, and standing ribs on the lower wall of the stem, so that the pipe may be supported on a table.

A still further object of this invention is to provide a strong, rugged, compact, and durable pipe of the character described, which shall give a cool smoke, which shall be easy to clean, which is so constructed that water or other cooling liquid may be readily inserted or removed, which shall be relatively inexpensive to manufacture, attractive in appearance, and yet practical and efiicient to a high degree in use.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements.

2 and arrangement of parts, which will be exemplified in the construction hereinafter described, and of which the scope of invention will be indicated in the following claims.

In the accompanying drawing in which is shown an illustrative embodiment of this invention,

Fig. l is a top plan view of the smoking pipe, with the bowl partly broken away, embodying the invention;

Fig. 2 is a cross-sectional view taken on line 2-2 of Fig. 1;

Fig. 3 is a cross-sectional view taken on line 33 of Fig. 2, and

Fig. 4 is a cross-sectional view taken on line 4-4 of Fig. 2.

Referring now in detail to the drawing, l0 designates a smoking pipe embodying the invention. The same comprises a stem II, a bowl l2, attached thereto by means of a screw l3, a cap I4 to close a chamber l5 for cooling liquid, formed in the stem, and a mouth bit I6 frictionally fitted withinthe rear end of the stem, and carrying a filter IT.

The stem ll may be made as a single member and is so constructed that it may be manufactured as a single die casting of suitable metal, such as aluminum or the like light metal. The stem l i may be provided with parallel side surfaces 20. It is formed with a curved under surface 2| and with parallel ridges 22 at the lower ends of the surfaces 20 and at the sides of the curved surface 2| forming standing ridges or ribs on which the pipe may be rested on a flat surface. The stem is formed at its front end with an internally threaded opening 23 and with an internal shoulder 24 at the inner end of the opening 23. The opening 23 communicates with the chamber 15 which extends rearwardly of said opening. The front end of th chamber [5 may be of circular cross-section. The stem is formed with a top wall 25 from which extends downwardly a longitudinal, radial web or fin 26. The front end of the fin 26 is spaced rearwardly from the shoulder 24, and the rear end of the fin is spaced forwardly of the rear end of the stem ll. At the lower end of the fin 26 is a longitudinal coextensive portion 21 of enlarged circular transverse cross-section, and formed with a through smoke passage 28. Adjacent the front end of the fin 26 is a vertical or transverse passage or bore 29, communicating with the front end of the smoke passage 28. The passage 29 extends to the upper side of the stem. Thus, the chamber [5 surrounds the fin 26 and portion 21 which is formed with the smoke passage. At the rearward end of the liquid chamber I5 is a transverse annular wall or partition 3| closing the chamber. Thus, the rear end of the fin 26 meets the annular wall 3| and its front end terminates at the rear end of the large front end portion of the chamber l5. The web or fin 2'6 divides the chamber into two spaced channels as seen in Figs. 3 and 4 of the drawing.

The stem H i formed at its rear end with a tapered opening 33. Extending from the tapered opening 33 is a filter pocket or chamber 34 which communicates with smoke passage 28.

At the top surface of the stem is a pair of arcuate grooves 35 concentric with respect to the passage 29 for the purpose hereinafter appearing. The upper end of the passage 29 is internally screw threaded as at 38 for the purpose hereinafter set forth.

The screw cap id has an externally screw threaded portion 4E) screwed within the threaded opening 23. Said screw cap furthermore, has a head ll which is knurled to facilitate turning the cap. A washer :32 may be interposed between one end of portion at of the cap and the shoulder 24.

The bowl it may be made of wood or of any other suitable material. is an annuiar ridge received in the grooves 36. It is also formed with a central opening 'i registering with the opening 38. The screw 13 which attaches ti e bowl E2 to the stem has a head 43 contacting the bottom of the bowl, and a screw threaded stem dd screwed into the threaded opening 38. The screw has a through opening 59 which communicates with the smoke passages 2e and 28.

The bit it; has a tapered portion 52 which fits into the tapered opening 33 in the stern. Said bit is formed with a through passage 53 having an enlarged passage at its front end forming a socket into which the rear end of the filter ii is frictionally fitted. The filter [1 projects into the filter chamber 34 of the stem, as shown in the drawing,

It will now be understood that water or other cooling liquid may be poured into the chamber or jacket for cooling the smoke, as it passes from the bowl through the passages 29, 28 and 34 to the hit i6. It will be understood that the stern extends beyond and under the bowl. The cooling liquid is poured into the front end of the stem. The smoke passage is supported by the fin and connected thereby with the top wall of the stem and is surrounded by the cooling medium. The internal fin also acts to dispel heat. that is, the inlet opening. It will be further understood that when the cap is removed to insert water or other cooling liquid, the smoke passage is not disturbed, and that is so because the opening for the liquid is separate and apart from the smoke passage. It will also now be understood that the stem ll may be made as a single die casting, and includes the smoke passage, the chamber for the cooling liquid, the filter cham- Formed at its underside" The liquid chamber has only one opening,

ber, the cooling fin, the bowl seat, the opening for the bit, the opening which receives the cap for closing the chamber for the cooling liquid, and it also includes thestanding ribs. 22. Thus, the single die casting includes a number of elements of the pipe.

t will thus be seen that there is provided a device in which the several objects of this invention are achieved and which is well adapted to meet the. conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as-illustrative and not in a limiting sense.

Having thus described my invention, I claim as.

new and desire to secure by Letters Patent:
