TOBACCO-PIPE.

Specification of Letters Patent.

Patented Oct. 24, 1911.

Application filed February 17, 1911. Serial No. 609,091.

To (LZZ whom it may concern:

Be it known that I, EUGENE GILBERT, a citizen of the United States, residing at Gladstone, in the county of Delta and State of Michigan, have invented a new and useful Tobacco-Pipe, of which the following is a specification.

It is the object of this invent-ion to provide a smoking pipe so constructed that the saliva will be prevented from finding its way into the bowl of the pipe, the material resulting from the burning, and destructive distillation of the tobacco, in the bowl of the pipe, being prevented from finding its way into the mouth of the user of the pipe.

I/Vith the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings,-Figure 1 is a longitudinal section, wherein sundry details appear in elevation; Fig. 2 is a transverse section on the line A-B of Fig. 1; Fig. 3 is a perspective of the primary tube and the element whereby the same is immediately carried; and Fig. 4 is a perspective of the secondary tube, together with its carrying element.

In carrying out the invention there is provided a tubular casing 1, into the upper end of which is inserted a plug 2, having a reduced neck 3 adapted to register closely in the bore of the casing 1, the neck 8 of the plug carrying a primary tube 4, extended downwardly within the casing 1, to a point adjacent the bottom of the casing. The pipe stem 5 is secured in the plug 2 by threading, or in any other desired manner, the construction being such that there is a continuous opening through the pipe stem, and through the primary tube 4.

The bore of the casing 1 is enlarged at its lower end, to form a chamber 6, into which is inserted the neck 7 of a cap 8, the neck 7 carrying a secondary tube 9 extended upwardly to a point adjacent the bottom of the plug 2, the secondary tube 9 inclosing the primary tube 4, the tubes being spaced from each other, and the secondary tube 9 being spaced from the adjacent wall of the casing 1. The cap 8 may be chambered out, to any desired extent, as shown at 10, below the secondary tube 9.

Adjacent its lower end, the casing 1 is equipped with a circumscribing rib 11, into which is inserted a short stem 12, communicating at one end with the bore of the casing 1. The outer end of the stem 12 is extended through the side wall of the bowl 14 of the pipe, there being a plug 15 in the bowl 14, positioned above the intake end of the stem 12. In the plug 15 there is an opening, through which is inserted a short depending tube 16, extended downwardly to a point adj acent the bottom of the bowl 14. A removable, closure cap 17 is fitted over the lower end of the bowl 14. As the tobacco burns in the bowl 14, the nicotin, passing downwardly through the tube 16, will find lodgment in the cap 17, which cap may readily be removed, to permit the nicotin to be poured off. The smoke will pass downwardly through the tube 16, and thence upwardly around the lower end of the tube 16, through the member 12. Should any condensation take place in the member 12, the condensate will find lodgment upon the top of the neck 7 of the cap 8, below the inner end of the member 12, the condensate being thus prevented from being drawn upwardly into and through the stem 5 of the pipe. The smoke, having entered the bore of the casing 1, through the member 12, will pass upwardly between the inner wall of the casing l and the secondary tube 9, over the upper end of the secondary tube 9, thence downwardly between the secondary tube 9 and the primary tube 4, thence upwardly through the primary tube 4 into and through the stem 5. The saliva and moisture, accumulating in the stem 5 and in the primary tube 4, will flow downwardly into the chamber 10 in the cap 8, the cap 8 being'freely removable, together with the secondary tube 9, to permit the accumulations in the chamber 10 to be drained away, when the secondary tube 9 and the cap 8 are inverted.

From the. foregoing it will be seen that the objectionable material resulting from a burning of the tobacco, will accumulate in the cap 17 the saliva and moisture traversing the primary tube 4, accumulating in the chamber 10 of the cap 8. It is obvious therefore, that the nicotin and other products resulting from the burning of the tobacco, cannot find their way into the mouth of the user, nor can the saliva and moisture find its way from the mouth of the user into the bowl 14 of the pipe. Owing to the factthat the smoke is forced to travel in a sinuous path through the tubes 4 and 9, the smoke will be thoroughly cooled before it is received into the mouth of the user of the pipe.

Having thus described the invention, what.

is claimed is In a device of the class described, a stem comprising a tubular casing; a closure for the lower end of the easing,'having a saliva chamber; an outer tube within the casing and terminally mounted in the closure, the outer tube communicating with the chamber, the closure being otherwiseimperforate in its upper face; a closure for the upper end of the casing, adapted to receive the mouth piece; an inner tube in the last named closure, located Within the outer tube and communicating with the chamber, below the outer tube; there being an opening in the side of the casing, adapted to receive bowlholding means, the opening being spaced above the upper face of the first named closure, to provide for an accumulation of liquid material from the bowl, upon the upper face of the first mentioned closure.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two Witnesses.

EUGENE GILBERT.
