To"all-,whom it may concern:-

" Be it known that I, VVILL'IAM C. BASTIAN,

a citizen of the United States, residing at ew York, in th State of New York, have invented new and useful Improvements in Stems for Toba-ccoof which the following is a specificaon.

. Thel present invention relates to pipes.

, vIts object is to provide a pipe in which the condensed vapors and salivawhich natural y collect in the stem,.will be prevented from passing to the bowl, and which, together with the products of distillation from the tobacco, will, to a considerable degree, be

vIn order that the invention may be clear to those skilled in the art to which it belongs, accompanying drawings a vpipe embodying my invention. vdrawings-Figure 1 is a view in lbntudinal section of a pipe made in ac- ...enlarged view in longitudinal vzii por nce with my invention. Fig. 2`is an section, of a part of the pipe stem. Fig. 3 is a view in transverse` section on line 3--3 of Fig. 2. Eig. 4 is a detail View in elevation, of the stem is probeing shown in dottedI lines.

the bowl 2 by a slip suitable mannerfis a bit, which is showny in. the present instance as made.v up of two parts, namely, the lpart l which is ttedto the bowl-stem 3, and has an enlarged chamber or pocket 5 at its upper end to which the smokefpassage 7 delivers, the upper end of said smoke-passage Joint, or in any V7, where it enters said chamber 5,V being la'red as at-8 to the diameter of the chamber y so as to form a valve seat, presently to be described. The said bit member 4`is coupled to a mouth-piece 9 by a screw-thread or other suitable connection 10, the bit 4 being pref erably enlarged or swelled at the pointof union to give a proper landing or. gunction of the two separable parts. Said bit mouthpiece 9 is, of course, traversed by a smoke- Specification of Letters Patent. Application med May 7, 1910. serial No. 560,051.

.member 13, and in passing through passage 11, as is customary, and, .as shown, the top wall of the pocket at the lower end ci the smoke-passage `11 at l the coupling end of the bit member 9 is flat, for a purpose presently to be described. It 'willbe seen that as thus constructed the ytwo-piecek bit is provided between its ends with a chamber or pocket to which the smoke passages to and from the bowl delivers, and through which the smoke must pass.` In the said pocket 5 is placed a valve member 13, Vwhich is of slightly less diameter than-the bore of the chamber 5, in. order that there maybe free passage between 4the valve member 13 and thewall of the chamber'. The said valve member 13 has a coned end 14 by preference, and a liat top-face 15, and such coned end seats in the valve-seat formed by the flared section 8 atthe point of union of the chamber 5 and smoke passage 7, so as to norm-ally close such passage 7. The said valve mem ber 13 is preferably made of a light absorptive substance, such, for example, as meerschaum, and at a point -removed from its lower end is provided with one `or more transverse passages or which connect with one 17 extending to the upper end of the valve member; the arrangement shown resulting in a cruciorm smoke passage with the vertical passage trapped at said valve member 13 is slightly shorter'than the chamber in which it is seated, so that it has a slight play back and forth' in the chamber 5 to close and 'open a passage above the flared valve-seat Sat the upper end of smoke passage 7.

When the pipe is in use, the said valve member 13, being 'of light material, will respond to suction on the bit, and lift, raising its con'ed'end 14 from the seat 8 andallowing the smoke to come from the bowl 2 by stem 3 and bit member l to chamber 5 this lifting ofthe valve member 13 at thesame time seating its upper dat end 15 against the inner flat wall 12 ofthe bit-member 9', so that smoke coming from Y to .chamber 5 can only pass to the passage 11 in bit-member 9 by traversing the passages 16 and 17 in the valve member 13. The

4result of this is that the smoke, prior to reaching the mouth of the smoker, must traverse passages in the absorbent valiget e Patented Jan. 3, 1911.

.the '1 passage 7 its lower end. The

passages the hygroscopic character of the i material of which Said valve member 1 3 1s -made will absorb and eliminate from the smoke the bulk of the liquid constituents held in suspension therein.

When suction ceases on the pipe the valve member 13 will drop to its closed position with its coned end 14 seated in the flared Sections f the bahwmber 4., and this win eifectually close :the smoke-passage 7 and.

preventany of the liquid of condensation which may have collected in the smoke passages, orany saliva from the mouth of the smoker from passing to the bowl 2; but hold it. in chamber 5 and passage 17 to be absorbed' by the valve member 13.

It will be understood that the valve member 18` may be renewed from time to time as it becomes saturated and foul, as these valve members may be jroduced at a slight thatthe disposition, size, and shape of the chamberthe valve-member, and in fact, all

of thel parts, may be varied; as this is a matter of fancy and design and in no `way a departure from my invention, which is not limited, except insofar as it is limited by the terms of the appended claims to the details of the present i lustrative disclosure.

v I claim:

1.. A pipe having a chambered bit, and a valve in said chamber havingA smoke-passages therein and normally 'closing the smoke-passage in said bit.' y

2.y A pipe having a chambered stem, and a .valveiin said chamber 1naving transverse and longitudinal smoke-passages therein and normally closing the smoke-passage in said bit. i

3. A lpipe having a chambered bit, and a valve in said chamberhaving a longitudinal passage extending partially therethrough,

. and a transverse passage entering said longitudinal passage; said valve normally closing f the smoke-passage in said bit.

4. A pipe having a chambered bit, and a valve in said chamber'closed at one en d and having a smoke-passage therein which delivers at the other end.y

5. A pipe havingy a chambered bit, and a valve closed at one end and having intertransverse and longitudinal smoke-passages which deliver at the other end.

6. A pipe having a chambered bit', and a valve in said chamber having a trapped smoke-passage delivering at one end thereof.

7. A pipe having a chambered bit, and a valve in said chamber havin a cruiform smoke-passage therein delivering at one end thereof. l

8. A pipe having a chambered bit, and a valve in said chamber having a cruciform smoke-passage therein which is trapped at one end and delivers to the bit passage at the other end. l 9. A pipe having a chambered bit, avalve` in said chamber having a trapped longitu-f dinal passage and a transverse passage passx ing diametrically through said valve and in-. tersecting said longitudinal passage.

10. A pipe having a chambered bit provided with a coned valve-seat at its lower end, a coned valve seated therein and normally closing'the smoke passage in said bit, a cruciform smoke-passage in said valve delivering at the top thereof, said valve having` a flat top seating snugly about the smoke passage when the valve is raised so as t'o confine the smoke to the bit passage.

11. A pipe having a chambered bit, a

valve in said chamber formed of absorbent' material and having a tortuous .smoke passage therethrough,said valve havin a closed lower end which normally closes t e smoke passage in the bit and having an open upper..end which delivers to the smoke passage in the bit. L

'12. A pipe having a chambered bit, a valve of absorbent material loosely fitting said chamber and having a, tortuous passage therein, said valve having a closed lower end which normally closes the smoke' passage in the bit,'and an open-upper end which delivers to the smoke passage in the bit.

13. A pi e having a chambered bit a, valve of ess length than the cham er' mounted therein and provided with a tortuous smoke passage therein, said valve having a closed lower end which normally closes the smoke passage in said bit, and an open upper end which delivers to the smokepassage in the bit.

In testimony whereof I have hereiinit'oset my hand in presence of two subscribing'` witnesses.
