2 Claims. I 1

This invention relates to improvements in pipes, and more particularly to a novel pipe including means for forcing a draft therethroug-h.

An object of the invention is to provide a device of the type containing manual means operable by the smoker to force a graft of air through the stem thereof at the will of the user.

Another object of the invention is to provide a simple direct action piston within a pipe stem for causing a draft therein.

Other and further objects of the invention will appear as the description proceeds, reference being had to the accompanying drawing, in

which: i

Fig. 1 is a side view in elevation of a smoking pipe embodying my invention.

Fig. 2 is a view taken on line 22 of Fig. 1.

Fig. 3 is a view in vertical section on line 3-3 of Fig. 2.

Fig. 4 is a view in perspective of the piston and connecting rod assembly in exploded relation.

Referring more particularly to the drawings, the numeral It refers to the mouth piece attached by frictional means to the stem I I, in turn attached to the bowl assembly I2. The tobacco receiving portion I 3 is preferably formed of briar or the like, has an external downwardly directed shoulder i4 and a plurality of draft apertures at I5 thereof, together with a central aperture at I6 to receive the anchoring pin IT. The portion I3 has a downwardly faced shoulder at I8 thereof on its exterior wall at the lower end thereof, which engages snugly on a gasket, which in turn engages the washer IS. The washer I9 has a downwardly directed flange which nests within the cup shaped bowl base 2 I, which latter is bottomed by the washer 22 which is centrally closed by the plug 23. The plug 23 is interiorly threaded to receive the lower threaded portion 2a of the pin A cooling jacket 25 comprisesa barrel-shaped multiple apertured sleeve which is held in place between a washer adjacent the shoulder I4 of member I3 and the gasket adjacent the washer I9 when the pin I7 is engaged in plug 23 after assembly of the parts. The base portion 2! of the bowl assembly I2, has a horizontally axially offset bore at 26 thereof to receive the plug sleeve 21 which accommodates the pusher pin 28 which is pivotally engaged at 29 to the short arm 30 of the bell crank 31. An integral ring and bracket member 32 is secured by the head 33 of the plug sleeve 21'. The bell crank 3! is pivoted by rivet means 35 to the bracket member 32. The free end 36 of bell crank 3| is pivoted by means 31 to the connecting rod 38, the latter having at its opposite end the piston assembly 39 which is adand 43, and securing mean 44 is engaged on pin' 42 after a movable piston segment 45 havingthe transverse slot 46 thereof, is placed over said pins M, 42 and 43, thus being secured for limited movements relative to the element 40.

The stationary element 40 of the piston assembly 39 is longitudinally bored at 48 and 49 thereof.

The pusher pin 28 is equipped with a coil ex-'" pansion spring 513 which is retained on said pin by the pusher pin head 5 I.

The connecting rod 38 has a curvature at 52 thereof and terminates in an eye 53 which receives the pivot means 3?.

The base portion 2| of the pipe bowl I2 has a reduced projection 54 which engages snugly within the large end 55 of the pipe stem I I, which in turn has a reduced portion 55 which engages within a mortise 51 within the mouthpiece Ii].

In use, the conventional packing of tobacco is placed in the bowl element I3. The smoke from the burning tobacco will pass downwardly through apertures I5 into the bowl base 2|, thence through the reduced projection 54 into the stem I I through the apertures at 48 and 49 of the element 46, and thereafter through the, slot 45 in movable segment is outwardly through the bore 53 in the mouthpiece It. It will be thus seen that the pipe may be smoked in the conventional manner by the user. A pressure on the pusher pin head 5i by the users thumb as the pipe is held in the left hand, will move the piston assembly 39 forwardly toward the pipe bowl within the bore of the stem I I to force a draft upwardly through the apertures I5 into the pipe bowl I3. There will be some forward movement of the air by the piston assembly due to the relatively small size of the openings 48 and 49. The coil spring 50 will then return the piston assembly in the direction of the pipe mouthpiece causing the segment 45 to seal the apertures 48 and 49 in the piston element 40 and effecting a suction in the cylindrical portion I I and a corresponding down draft within the pipe bowl element I3. This operation may be made during the normal smoking procedure, or while the pipe is being merely held in hand, to maintainthe tobacco in a burning condition, thus obviating the frequent annoyance of having the pipe go out.

The piston segment 45 is freely held on the pins 4|, 42 and 43 and during rearward movement of the piston assembly 39 toward the mouthpiece, the said segment 45 will seal the openings in piston element '40. During forward or bowlwise movement of the piston element 40 the segment 45 will tend to lag or separate from the piston element 40 because it is freely, slidingly held on the pins 4|, 42 and 43. Air will then be free to pass through the openings at 48 and 49 of the piston element 40 and through the slot at 46 of the segment 45, thus permitting the piston element 40 to move forwardly with less air resistance. However, there will be some forward movement of the air by the piston assembly 39 in view of the relatively small size of the openings 48 and 49, as stated above. When the pipe is smoked in the conventional manner, the natural suction created by the smoker will tend to withdraw segment 45 from the piston element 40, permitting the smoke to course through openings 48 and 49 of the piston element 48 and the slot at 4B of segment 45.

It will be understood that the device is capable of many modifications in structure and design, without departing from the spirit of the invention, within the scope of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States, is:

1. A smoking pipe comprising a tobacco bowl, a stem having an enlarged bore for a portion of its length, a piston assembly reciprocable therein and having vent means longitudinally therethrough, a bell crank subjoined to said bowl for actuating said piston assembly, a pusher-pin extending exteriorly of the base of said bowl and connected to said bell crank, and spring means for maintaining said pusher-pin in extended position.

2. A smoking pipe comprising a tobacco bowl having a plurality of bottom vents, a cup member subjoined thereto, a stem having a bore, a reduced bored extension on said cup member engaged within an end of said stem, a piston assembly reciprocable within the .bore of said stem, a bell crank mounted on a vertical axis within said cup member, a connecting rod between said piston assembly and said bell crank, the said cup member having a bore horizontally ofi-set from said stem, a pusher pin slidably mounted within said last-mentioned bore, and a coil spring on said pin for outward return of the latter.
