UNITED STATES JOSEPH M. MUR, OF NEW YORK, N. Y.

IMPROVEMENT IN TOBACCO-PIPES.

Specification forming part of Letters Patent No. 119,941, dated October 17, 1871.

To all whom it may concern:

Be it known that I, JOSEPH M. MUR, of the city, county, and State of New York, have invented certain Improvements in Tobacco-Pipes, of which the following is a specification:

My invention consists, mainly, in the employment of a separate and detachable metallic cup between the fireproof bowl and the outer casing for the purpose of collecting the essential-oils and other deleterious matter produced by burnin g the tobacco.

Figure 1 is a sectional elevation of my invention. Fig. 2 is an elevation of the fire-bowl and packing-ring. A is a cylindrical bowl of pipe clay or other suitable substance, in which the tobacco is burned, and which is provided with a flange, 1), around its upper edge. B is the bowl proper of the pipe, and is bored out or otherwise made hollow to receive the firebowl A, and leave an annular space between the two. O is a thin metallic cup placed between the bowl A and outer shell B, and which operates to retain the ashes or other deleterious matter from the tobacco. The diameter of this cup is such that there is a slight space between it and the fire-bowl and also be tween it and the shell B, and it may rest either upon the bottom of such shell or upon a slight projection, 0, left therein in boring. The smoke drawn out of the burning tobacco passes through the openings 0 upward over the edge of the cup 0 and thence to thestem through the passage f in the shank of the pipe, as indicated by arrows in Fig. 1. A packing-ring, d, is placed upon the outside of the fire-bowlAunderthe flange b, composed of cork or other suitable yielding material, which fits tightly into the upper part of the shell B, the opening in the latter being :made slightly conical to receive it and allow of its being pushed down tightly to its place.

By this means the smoke-passages are kept perfectly tight and no difficulty is experienced by the smoker in creating a suction or draught through the pipe-stem. The metallic cup 0 rests loos'ely in the shell B, and may be removed and cleansed of the impurities collected in it. The fire-bowl, also, when it becomes filthy and saturated with deleterious matter, may be easily removed and replaced with a newone at a trifling expense. The non-conductin g material of the pipe-bowl preserves thepacking-ring dfrom burn- 111g.

What I claim as my invention, and desire to secure by Letters Patent, is-

As an improved article of manufacture, a tobacco-pipe provided with a separate and detachable ash-cup, c, placed loosely between the fireproof tobacco-bowl B and the outer case or shell A, substantially as and for the purposes shown and described.

JOSEPH M. MUB.
