Application August 4, 1949, Serial No. 108,644

1` j This invention relates to pipes having ash and heel ejectors and the principal object of the'invention resides in the provision of a pipe having a bowl and there being an upstanding bushing or the like therein, said bushing forming a well in the body of the pipe and slidably receiving. a push rod having thereon a flexible steel ash and heel ejection plate and including Van ejector handle which Yis normally adapted to lie under a part of the pipe in substantially housed condition, but which may be swung around on a pivot on the ejector plunger to operate the same rectilinearly to eject material from the bowl of the Dlpe. Y

Further objects of the invention include the provision of apipe as above stated including a cover firmlyA secured tothe plunger and covering the bushing so asto prevent entrance of tobacco iuice and particles thereinto; the provision of the device as aforesaid including a heat resisting rubber shield forming a tight but flexible closure completely preventing the entry of tobacco juice and particles to the plunger; and the provision of a pipe of the class described having a. slotted ash ejector plate,l the Vsame being flexible and adapted to be'movable'in the Vpipe evenr though it should tend to stick.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing in which:

Fig. 1 is a central longitudinal sectional view through a pipe according to the presentk invention;

Fig. 2 is a top plan view thereof; Y Fig. 3is afragmentary view in elevation;

Fig. 4 is an enlarged sectional view illustrating the ash ejector plunger;

Fig. 5 is a top plan view of the plunger;

- Figs. 6 and 7 are detailed views of the plunger` and handle; and

Fig. 8 is an enlarged view in section showing a ball catch for the handle, said ball catch maintaining the same in housed condition shown in Fig. 3.

In carrying out the present invention, there is provided a more or less conventional pipe stem I0 which ts into the body I2 of the pipe and which may be held therein by a bushing I4. The body I2 is preferably molded plastic, but may be any suitable material, such as wood, metal, etc.

The body I2 is provided with a bottom longitudinal slot I6 which is adapted to at leastV partially house a lever or handle I8 which extends rearwardly and is pivoted at 20 to a plunger 22 extending vertically in upright condition in a Y s claims'. (c1. isi- 183) bushing 24 which may be formed as a part of the body I2 and provides therewith an annular well 26. The bushing 24 is here shown as made up of two parts tted together, and is provided with screw threads 28 which mesh with like screw threads on a bowl 30. The portion of the bushing containing the screw threads 28 is cut out as at 32 to allow the passage of smoke from the bowl of the pipe down into the well 26, and a gasket 33 may be used between the bowl and the body I2.

Theplunger 22 is provided at its upperrend with a cover 34, this cover being shown in detail in Fig. 4. The plunger 22 is surrounded by a compression spring 36 which provides for correct alignment of the 'plunger in the bushing 24 during the ejecting action, i. e., reciprocation of the plunger. vIt is to be noted that this spring has been inverted in Fig. 4 as compared with the Fig. 1 showing thereof, and the spring may be assembled in the device in either way. Also, this spring may be made of thicker or thinner wire depending on choice or design, as illustrated in Figs. l and 4.

Above the cover there is provided a thin flex'- ible stainless steel element 38. This element is slotted radially as at 40, see Fig. 5, for the purpose of increasing the flexibility thereof so that if it sticksin the bowl, it may, nevertheless be pushed up to complete the cleaning action. The diameter of the element 38 is slightly less than that of the bowl of the pipe.

A heat resisting rubber shield 42 may be sealed to the cover 34 as at 44 and to an upstanding boss at the bottom of the recessv provided by bushing 24, see 46 in Fig. 4, but this shield'rnay be omitted as shown in Fig. l. A form of silicon rubber is usable for the purposes stated, and the shield may be such as to overcome the action of spring 36.

The handle I8 is maintained in its inoperative position as in Fig. l by a double ball catch arrangement 50, this comprising a pair of balls spring pressed apart and fitting in a bore 52 of the handle so that the balls yieldingly press upon walls 54 of the pipe part I2 forming a slot for the reception of the handle I8.

In the operation of the device, after a pipe full has been smoked, it is merely necessary to grasp the ns on the handle I8, bring the handle down, and move it in an upward direction to clear the pipe bowl. If cleaning element 38 tends to stick, itis flexible enough to be rammed through the bowl without injury, and as seen in Fig. l, it is clear that the element 38 is a little smaller in diameter than the bowl of the pipe to allow a desired degree of caking.

The smoke will pass down past cover 34, through the holes 32, and into the well 26, and of course the same is true of moisture which is, however, kept away from plunger 22 by the cover 34 and shield 42. This shield is not in all cases necessary, but it improves the cleanliness and sanitation of the pipe. Moisture and detritis will be caught in the well 26 below the level of the smoke hole 56. Another protection against moisture entering the bushing and impinging on plunger 22 resides in the collar 58 which acts as a barrier. This collar may be integral with cover 34 and has a V-section, the apex of which points downwardly. It will be clear that this invention provides a sanitary and clean ash ejector which will always remain clean due to the cover 34, shield 42, and other details of the construction of the device.

Having thus described our invention and the advantages thereof, we do not wish to be limited to the details herein disclosed otherwise than as set forth in the claims, but what we claimV is:

1. A pipe comprising a pipe body, a stem therefor, said body having a hollow portion, an up"- standing wall forming a central bore and a surrounding well in the hollow portion, a slotted threaded head on the wall, a bowl threaded thereon and seating on the pipe body, a plunger in the bore, a bowl cleaning element on the plunger above the wall, and a jointed handle for the plunger to reciprocate the bowl cleaning element.

2. A pipe comprising a p-ipe body, a stem therefor, said body having a hollow portion, an upsta-nding wall forming a central bore and a surrounding well in the hollow portion, a slotted threaded head on the wall, a bowl threaded thereon and seating on the pipe body, a plunger in the bore, a bowl cleaning element on the plunger above the wall, and a jointed handle for the plunger to reciprocate the bowl cleaning element, the latter being slotted and flexible and of a diameter less than that of the bowl.
