TOBAGO() PIPE.

Application led March 3, 1923. Serial No. 622,583.

To all whom il? may cof/wem:

Be it known that I, ALFRED HACKETT, a subject of the King of Great Britain, residing in the city of Toronto, county of York, Province of Ontario, Canada, have invented certain new and useful Improvements in Tobacco Pipes, of which the f ollowing is a specification.

My invention relates to improvements in tobacco pipes, and the principal object of l my invention 1s to construct a tobacco pipe which will insure at all times theffreedom from saliva of the tobacco in the bowl, thus insuring a sweet smoke. Another object of my invention is to construct my pipe so that the mouth piece may be readily removed The stem A of the bowl B is provided' with a uniform bore C for the major portion of its length, larger than the usual bore, and

` this uniform bore is provided with theuniform lining D, made of metal. There is no necessity of removing the lining D when it has been placed in position, as the neck E of the mouth piece F is removably sup- Y ported in the outer end of said lining, which outer end is .preferably flanged as Shown at 4 Gr so as to face against. the outer end of the stem A. rlhe inner end I-I of said lining is closed, except for an opening through which extends a conduit I. which ts a hole J formed in the bottom of the bowl B and opening into the bottom of vthe cavity in said bowl at one side thereof in the usual Way. This conduit I is coupled to the lining D through the medium of the inner end H thereof so that said conduit will be positioned when said lining 'is positioned.

Mounted within the mouth piece F and projecting beyond the inner end thereof into the lining D is a, conduit O, preferably the same diameter as the conduit I, and substanameter of the lining D.

The lined bore C, in combination with the conduits I and O, form a well or trap, and it is evident that the saliva flowing down said conduit O will pass into the said trap or Well, in place of continuing through the conduit I into the cavity of the bowl B.

It is believed that a considerable percentage of the waste products of combustion, so to speak, contained in the smoke from the smouldering tobacco, as the smoke leaves the conduitI, will remain inthe well or trap, thus appreciably reducing the percentage of suchV waste products of ycombustion that reach the smokers mouth. Y

The tobacco in the bowl B will be free of admixture with the saliva, and a cooler and sweeter smoke will result.

What I claimy is:

A tobacco pipe having a bore of uniform diameter longitudinally formed in the straight stem thereof for the major portion of its length, the inner end of said bore terminating short of the cavity in the bowl; a metal lining of uniform diameter `having a circular inturned flange at its inner end permanently mounted in said bore, and having its flanged inner end fit against the inner end of said bore; a metal conduit having its inner end mounted in that portion of the bowl of the pipe separating the inner end lof said bore from said cavity, and extending through the inner end of said lining; a mouth piece having v`a neck adapted to fit within the outer end of Said metal linin and a metal conduit mounted within sai mouth piece for the length thereof and extending beyond said neck into said metal lining, the inner ends of said conduits being spaced apart.

ALFRED HACKE'IT.
