IMPROVEMENT INToBAcco-PIPES.-

Specification forming partof Letters Patent No. 41,778, dated March 1, 1864.

smoke shall be cooled and deprived of its nicotineand 'the water from the sponge prevent- -ed .from flowing into the stem or coming in contact with the tobacco, as hereinafter described.

The vinvention also consists in a combination of the sponge with arod and perforated plates, in a manner and for a purpose fully specified hereinafter. i

In order to enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation. i

On reference to the accompanying drawings,- which form a part of this speoifcatiomligure 1 is an exterior view of my improved tobacco-pipe; Fig. 2, is vertical section, and Fig. 3 a transverse section on the line 1 2, Fig.' 2.

Similar letters refer to similar parts throughout the several views.

A is a hollow cylindrical case, closed at the bottom and having an inclined tube, B, corn municating with the interior of the case through the opening w. fits the lower end ot' a cup or bowl, C, similar in form to the bowls of ordinary tobacco-pipes, and communicating with the interior of the case A through an opening, y.

Into he end` of the tubev B fits the lowerien( of 4a tube or. stem, D, to which is attached the ordinary mouth-piece, E. I

To the Vertical rod f, which is bent at the upper end so as to form a handle, c, are secured 'the perforated metal' plates e and e', adapted to fit snugly, but so as to move freely in the inside of the case, and between the two plates, and surrounding the rodf, is a sponge, G. The lower end of the rod f extends below theplate e to a sufficient extentv to maintain the latter abovethe opening ac, thus forming below the plate cfa chamber, G', for a pur-A pose described hereinafter.

In the top of the ease.

When the pipe is to be used, the bowl is re moved, the rod j, with its plates and sponge sponge saturated with water, after which it is again inserted in the case and the bowl .re-

-`placed and iilled with tobacco. As the smoke is drawn from the burning tobacco into the stem D, and thence to the mouth, it must pass forations in the plate e, through the interstices ofthe saturated sponge, the perforations ofthe plate e', and the opening x. As the smoke passes through the sponge, the waterthe'rein not only cools the smoke, but also absorbs the noxious nicotine.

w below the sponge, and ,above the bottom of the case any water which `may be drawn` from the sponge, instead of entering the stem D., as would be the ease in ordinary pipes, will flow into the chamber beneath the plate e; and in case the position of the' pipe should at any time be wholly or partially reversed,`the waand be again absorbed by the sponge without coming in contact with the tobacco or flowing becomes foul from the vquantity of nicotine absorbed, thev bowl may be removed and the or substances may be used in place of the sponge.

Y I claim` 1.. The sponge G, or its equivalent, adapted to the case A, and arranged in respect to the openingvw, and the bowl C, or its equivalent, substantially as and for the purpose set forth.
