Application filed July 3.1907- Serial No. 381,977.

invented certain new and useful Improve-- ments in Pipes, of whichthe followingr is a specification.

This invention relates to smoking pipes and has for its object the production of a pipe in which means are provided for lifting the tobacco in the ,tobacco receptacle slightly above the smoke orifice in order that a suitable draft may be insured.

The inventionconsists in certain novel fean tures of construction and arrangement of parts which will be readily understood by reference to the description of thedrawings and to the claims hereinafter given.

Of the drawings: Figure 1 represents an inverted lan of a pipe embodying the features of tliis invention. Fig. 2 represents a transverse section of the same, the cutting plane being on line 2--2 on Fig. 1, and Fig. 3 represents a sectional detail, the cutting planebeing on line 3-3 on Fig. 2.

Similar characters designate like arts throughout theseveral figures of the trawinffs.

laIn the drawings, 10 represents the bowl of a Lpipe provided with an interior chamber 11 a apted to receive a4 charge of tobacco. From a point near the bottom of the bowl 10 projects the-usual stem 12 having a smoke orifice 13 extending therethrough and communicating with the interior of the tobacco receptacle 11 near the bottom thereof. The bowl 10 is provided with a conical opening 14 extendinU'throug-h the bottom thereof, the upper end of this opening being of greater diameter than the lower end. lbnto this opening 14 is fitted a conical lug 15 the lower'end of which is provided wit a knob 16 by which the plug may be manipulated and moved endwise inthe opening 14.

Extending through the plug 15 is a pin 17 ada ted to engage the lower face of a hub 1S on t e bottom of the bowl 10, thus preventing an inward movement of the plug, while the conical wall of the plug fitting the opening 14 prevents any outward movement thereof.

Extendinglaterally from the opening 14 are two diametral depressions 19 extending slightly into the bottom of the bowl 10. Normally the plug is in the position shown in Figs. 1 and 2 and in this position the recepl tacle 11 is filled with tobacco to be used. l/Vhen the tobacco is properly packed within the receptacle it is liable to be packed so hard as to prevent a proper draft through the smoke orifice 13. To overcome this objection and provide a means-ofclearing the mouth of the smoke orifice is the object of the plug 15 which is mounted inthe bottoni of the bowl directly in front of the mouth of the orifice 13.

When the receptacle 11 has been -filled with tobacco the smoker takes hold of the handle 16 and by giving it a turn about its axis so that the projecting ends of the pin 17 are brought into the same plane as the lateral dc-' pressions 19 he presses the plug 15 inwardly against the bottom of the tobacco and raises it slightly above the mouth of the orifice 13, the projecting ends of the pin 17 moving in the depressions 19 during this operation. As soon as the tobacco has been raised sulliciently to clear the orifice 13 and create a clearance between the bottom of the tobacco and the interior of the bowl 10, the plug is returned to its normal position and turned about its axis so that the projecting ends of the pin 17 will impinge upon the lower face of the hub 18 and engage the plug in position to prevent further movement.

This makes a very simple device which overcomes a very serious defect found in most pipes, the objections to which it is believed will be fully apparent without any further description.

Having thus described my invention, l claim:

1. A tobacco pipe having a tobacco receptacle provided with an opening through the bottom, and a smoke ori'lice, in combination with a plug itting said opening and adapted for movement therein to covei and uncover the end of said smoke orifice, and means for preventing the removal of sa'id plug from said opening.

2. A tobacco pipe having a tobacco regeptacle provided with an opening through the bottom, and a smoke orifice, in combination with a plug fitting said opening and adapted for movement therein to cover and uncover the end of said smoke orifice, and a pin extending through said plug adapted to engage with the bowl when the upper end of said plug is moved beyond said smoke orifice to prevent further movement in that direction.

3. A tobacco pipe having a tobacco receptacle provided with a conical opening through the bottom the lesser diameter of which is at the outer end, and a smoke oriiice, in combination with a conical. plug adapted to fit said opening provided with means at its outer end for moving said plug inwardly, and means for limiting said inward movement.

4. A tobacco pipe having a tobacco receptacle provided with a conical opening through the bottom the lesser diameter of which is at the outer end, and a smoke orifice, in combination with a conical plug adapted to t said opening provided with means at its outer end Jfor moving said plug inwardly, and a pin for 15 limiting said inward movement.

5. A tobacco pipe having a tobacco receptacle provided with an opening through the bottom with exterior lateral depressionsl communicating with said opening, and a smoke orifice, in combination with a plug fitting said opening and adapted for movement therein to cover and uncover the end of said smoke orifice, and projections on said plug 'adapted to enter said lateral depressions when said plug is moved inwardly.
