SMOKING PIPE Filed May 9, 1940 nvenlor /zzdiem an VJ A Homey Patented Jan. 14, 1941 UNITED STATES PATENT orricla:

3 Claims.

The present invention relates to new and useful improvements in smoking pipes and has for one of its important objects to provide, in a manner as hereinafter set forth, a device of this character embodying a construction and arrangement whereby saliva will be positively prevented from getting into the bowl'.

Another very important object of the invention is to provide a smoking pipe of the aforementioned character comprising a removable filter of a novel construction and arrangement through which the smoke must pass before reaching the mouth.

Other objects of the invention are to provide a smoking pipe of the character described which will be comparatively simple in construction, strong, durable, sanitary, light in weight, attractive in appearance and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specication, 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 in vertical longitudinal section through a smoking pipe constructed in accordance with the present invention.

Figure 2 is a top plan view of the pipe.

Figure 3 is a perspective view of the lter holder.

Figure 4 is a detail View in side elevation of the perforated grate or pan.

Referring now to the drawing in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a stem I of suitable material, said stem having a comparatively large bore 2 extending from end to end thereof. Threadedly mounted in the rear end portion of the stem I is a bit or mouth piece 3.

On the forward portion of the stem Iis a bowl 4. 1n the rear portion of the bowl 4 and extending over the rim or top thereof is a groove or channel 5. Formed integrally with the rear portion of the bowl 4 is an enlargement or protuberance 6 which merges with the stem I. Extending downwardly through the protuberance 6 is a passage 1 which communicates with the bore 2 of the stern I.

The groove or channel 5 is for the reception of a tube in the form of a gooseneck 8 having one end portion engaged in the passage '1. On the other end of the gooseneck 8, and located in the lower portion of the bowl 4, is a substantially con- (Cl. ISI- 183) cavo-convex perforated grate or pan 9. It will be observed that the gooseneck communicates with the bowl 4 below the perforated grate 9.

Removably mounted in the bore 2 of the stem I is a filter holder which is designated generally by the reference numeral Ill. The holder I0 comprises a plug II which is threaded into the forward end portion of the bore 2. Projecting rearwardly from the plug II is a plurality of spaced rods I2 having mounted thereon a foraminous tube I3. The foraminous tube I3 is for the reception of a suitable filtering element I4.

It is thought that the manner in which the pipe functions will be readily apparent from a consideration of the foregoing. Briefly, when the bowl 4 is lled the tobacco placed therein rests on the perforated grate 9. Thus, when the pipe is lighted and drawn on the smoke passes downwardly through the perforated grate 9, through the gooseneck 8 over the top of the bowl 4, downwardly through the passage I into the bore 2 where it passes through the filter I4 in the holder IB, thence through the bit or mouthpiece 3. It will thus be seen that the construction andarrangement is such as to positively prevent saliva from entering the bowl 4, said. saliva being absorbed by the lter I4. The holder I0 may be expeditiously removed for replacing the lter I4 by simply screwing the plug II out of the bore 2. Due to the fact that no saliva may enter the bowl 4 substantially all of the tobacco may be consumed and a cool, dry smoke had. The perforated grate 9 may also be conveniently removed if desired by lifting the gooseneck 8 out of the groove or channel 5.

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

What is claimed is:

l. A smoking pipe comprising a stem, a bowl on said stem, a gooseneck mounted on said bowl and communicating therewith at one end, the other end of said gooseneck communicating with the bore of the stem, and a grate mounted on said one end portion of the gooseneck in the bowl.

2. A smoking pipe comprising a stem, a bowl on one end portion of said stem, said bowl having a smoke passage in its rear portion communicating with the bore of the stem, a gooseneck mounted on the bowl and having one end portion engaged in the passage, the other end of the gooseneck communicating with the lower portion of the bowl, and a perforated grate on said other end of the gooseneck.

3. A smoking pipe comprising a stem, a bowl on said stem, an integral protuberance on the rear portion of the bowl merging with the stem and having a smoke passage therein communicating with the bore of said stem, said bowl having a groove in its inner wall extending over the top thereof, a gooseneck mounted in the groove and communicating at one end with the passage, the other end of the gooseneck communicating with the lower portion of the bowl, and a substantially concavo-convex perforated grate on said other end of the gooseneck.
