Mwy IMPROVEMENT INA TOBACCO-PIPE STEM.

The Schedule referred to in these Letters Patent and making part "of the same.

To `all fivhom it' mavyconcern Be it known that I, EDUARD LARSSEN, of Stavanger, in the Kingdom of Norway, have invented a new and useful Improvement vingStems for TobaccofPipes; Vand `I do hereby declaretheibllowng to be a full, clear, and exact description thereof, which will enable others skilled in the art to which my invention appertains, to make and usel the same, reference being had to the accompanying drawings, forming part of this specification, in` which` Figure l is anclevation of my improved pipe-stem;

Figure 2, a transverse section of the same, throughv tween t-he bowl 'and stem, and connected to each byshort tubes, through which the smoke passes.

These, pipes, however, from their peculiar construction, are incapable of being moved from place to place, and are cumbrous and unwieldy.

The object of `my invention is-to adaptthe stem of an ordinary tobacco-pipe for containing water, so that it may be conveniently carried in the pocket, and used whenever desired, thus combining pcrtableness with the luxury ot the water-pipe.

The invention consists 1n the combination, with the stem of the pipe, which isenlarged iu diameter to contain the requisite quantity of water, oi' two interior bent tubes, the plugs by `which such tubes arey heldin place` wit-hin the short tubes attached to opposite ends 'of the cylinder;v one furnishing the mouth-piece of the stem, and the other the means for attaching the stem to an ordinary pipe-bowl. V

It also consists in the combination, with the vstem and interior tubes, 'of a ball-valve, by which the water contained inthe stemV is prevented from iiowing into the bowl of the pipe, as will be hereinafter more fullydescribed. y

'In the accompanying drawings- A is the stem, adaptedrto be applied to an ordinary pipe-bowl.

is the cylinder ormain portion of the stem, com,

posed of glass, wood, or other suitable material.

I prefer to employ glass., either white`or colored, as being the cheapest and most ornamental.

of reference indicate i corresponding stem or cylinder, and 'two caps or C and D are caps or short tubes, formed of vulcanized rubber, Orother proper material.

The former is adapted to receive, at its upper end a,

the mouth-piece of the stem, and the latter is some- .what elongated and made tapering, in order to fit the bowl 'of a pipe.

These tubes are attached to the cylinder B at' opposite .ends by any suitable means in such a manner as to be readily removed when desired.

In this example of my invention, I have employed rubber packing-rings b, interposed between the cylin` der and tubes, as a means of forming the connection. c d are bent tubes, of glass, metal, or other material,

arranged longitudinally within the cylinder-B, and tit-- ting within one another in a links of a cham, although this precise arrangement is not absolutely essential 'to their successful operation'.

Each tub'e is secured, at its outer end, to a plug, f,

of rubber, cork, or other proper substance, tting the ends of the cylinder B, as clearly shown in rigs. 3 and 4. The inner ends of these tubes are arranged at opposite ends of the cylinder, near the plugs f, and open directly into said cylinder. v

The operation is as follows:

'Ihe cylinder is partially iilled with water, either in its natural state or. perfumed, to about the height indicated at g, rigs. 3 and 4, and the tube D inserted in v the bowl of a pipe containing 'burning tobacco. The smoke, as it.is drawn through the stem in smoking, passes through the tube D, and enters the outer end ofthe interior tube c, through which it passes, audis discharged into the'water contained inthe cylinder, at its inner end h, seen in fig. 4. Fromtheuce it passes directly through the water, and enters the end t' of the tube d, as seen. in-g. 3, following the course of said tube until it is discharged through the cap G into the mouth ofthe smoker.

It will be observed that the smoke in its passage` Ithrough the tubes cd is exposedto an increased cooliug'surf'ace, because-both branches of cach lpipe pass through the water.

By thisarrangement the smoke is rendered exceedingly cool and agreeable tothe taste.

In filling the cylinder Bwith water, the cap G is removed and the plug f raised sufficiently to permit the Water to be poured in around it. When, however, the

vwater becomes impure', it is discharged through the Y tube D, (the latter having been previously removed from ,the bowl,) by blowing with the breath through the mouth-piece. f The tube c then operates as a siphon, as will be readily understood.

It frequently happens in lighting a pipe, that the smoker will blow through it slightly to ascertain if the tobacco is ignited. If this were attempted with my improved stem, ,the result would be as above indicated,

manner similar to the` that is tosay, the tube c would operate as a siphon to.

discharge the Water from the cylinder. To guard against this contingency, I have arranged a ball-valve, m, seen in fig. 4, within a recess formed inthe cap D. The valve is limited in its movements by the seat n and guard 0, as will be readily observed.

Instead of placing the valve directly Within'the cap D, it may beenclosed in a thin elastic case or diahravm Whose u er end sserves as a achimv p o a 1 p 1 s a:

ring between the cylinder B and tube D, aslelearly shown in iig. 3. f When the valves are employed, it will `be apparent that the water contained inthe cylinder cannot be expelled through the tube D, but must be discharged by removing the cap C and plug f in the manner previously described for its introduction.

My improved` pipe-stem is economical in construction, easily operated, and can be applied with the ut. most ease to any ordinary pipe-bowl. By its use the smoker can enjoy the luxury of the Water-tobacco pipe at a comparatively trifling expense.

Having thus described my invention,

What I claim therein as new, and desire to secure by Letters Patent, is

1. In combination with the cylinder B, adaptedto contain water, the interior bent tubes c. d, plugs f, and

caps or short tubes C D, substantially as'herein shown
