10 Claims. (01. 131-12) This invention relates to smoking pipes, and it is the primary object of the invention to provide improved closure means for the mouth of the pipe bowl slidably mounted upon the bowl whereby the closure means is adjustable to open the pipe bowl to permit of filling tobacco therein and after the tobacco has been lighted adjusted to close the bowl mouth whereby the pipe with the tobacco therein may be placed in the pocket of the user,

in a drawer, or other places, and the tobaccoand ashes will be retained in the pipe bowl and can: not escape from the pipe bowl intoand soil the pocket of the user or any other place where the pipe may be placed, and in case the tobacco is lighted with the possibility of burning the -ap parel or setting fire where the pipe may be placed by the burning tobacco spilling from the pipe bowl. The closure means also serves as a shield when the pipe is used outdoors, as by motorists,

a smoking pipe having a novel arrangement of pipe bowl whereby the pipe may be set upon a horizontal surface without the possibility of the pipe tipping over and spilling the tobacco orash'es therefrom by arranging the pipe bowl of circular form with the mouthextended into aperiphe-ral portion of the bowl and the stem extended tangentially from-the peripheral portion of the bowl opposite the bowl mouth and are ranged at the juncture thereof with the bowl with a flattened portion. 7 a

Another object of the invention is -to provide;

asmoking pipe wherein the pipe bowl is arranged externally with laterally extending projections in the :form of ribs to increase the area of the outer surface-of the bowl for dissipating the heat from the pipe bowl transmitted thereto-from the burning tobacco and maintain the pipe bowlsufii- '45 ciently cool to be grasped between the fingersvor held in the hand without injury by the heat-o1 the bowl. x

In carrying out the embodime tot the invention illustrated in the; drawing, the bowl 10 is arrangedin the form of -a circular or cylindrical body Provided with a chamber 11 extending diametrically of the bowl, withthe .mouth opening through a peripheral portion of the bowl and a stem 12, integral with the bowl, extending tangentially of a peripheral portion of the wall of the bowl; opposite the mouth of the bowl chamber and'latena 'lyfirom the bowl in angular relationto the mouthof the :bowl chamber, and shown as extending substantially at a right angle to themouth f the bowl chamber, said stem having a boretherethrough communicating with the bowl chamber, and a mouth piece 13 removably, connected to the stem in a conventional mariners, At' theyiuncture of the stem with the bowl there is arranged a boss having a flattened surface to extend in the plane of a peripheral portion of thebowl, as at 14,=to serve as a base to engage and supportthe pipe upon a horizont'al surface with the -month ofthe bowl chamber uppermost and prevent the spilling of tobacco and ashes-{ram the, bowl chamber. To permit of the placing of the pipe in the pocket of the apparel ofthe ser with part of the tobacco which has not been-consumed in the pipe bowl, or with the tobacco lighted, and preventing the soiling or? burning of the pocket bythe tobacco or tobacco ash spilling from the bowl chamber, -or when placed elsewhere, as in :a drawer bowl chamber; comprising a plate 15 bifurcated at one end, as at 1-6, and arranged to arcuate shape in longitudinal section to conform to the curvature of the periphery of the pipe bowl,

said plate being slidably mounted on the pipe bowl to have adjustment in a direction toward and the legs of the bifurcation straddling the pipe stem to uncover the mouth of the bowl chamber and in a direction away from the pipe stem to cover the mouth of the bowl chamber.

Means are provided to slidably mount and yieldingly hold the closure plate on the pipe bowl and guide the closure plate at the opposite sides and in the embodiment shown as comprising plates formed to angle shape in cross section, as shown in Figure 6, the one angle portion 17 being arranged to arcuate shape in longitudinal section to conform to the curvature of the periphery of thepipe bowl, the other angle portions 13 of said members having an vedgeof arcuate form and adapted to be engaged in parallel slits or recesses 19 of like shape arranged in the pipe bowl as by a circular saw, the depth of said recesses or saw cuts being slightly less than the width of the angle portion 18 so that the angle portion 17 will be spaced from the pipe bowl a distance slightlygreater than the mouth to the bowl chamber, as shown in Figure 2, or partially cover the same, or in mouth uncovering position, as shown in Figures 1 and 3,

the mounting members for the closure plate are made of resilient material and the angle portion 1'7 is-partially separated from the angle portion 18 by a slit 20 extended inward from one end toarrange the one -end oi said angle portion 17 as a yielding tongue, as shown at 17 in Figure 6, and said tongue is deflected slightly inward in the direction of the portion 18 to restrict the space between said tongue of the angle portion 1'? and the pipe bowlto yieldinglyand friotionally engage the portion of the closure plate interposed between said tongue 17' and the pipe bowl and thus hold the closure plate in any of its adjusted positions. In the position of the closure plate uncovering the mouth of the bowl chamber, the bifurcation legs engage at'opposite sides of the pipe stem and the pipe lstem limiting the uncovering movement of the closureplate; To limit the mouth closing movement of the 010- sure plate, an abutment 21 is mounted in the pipe bowl for the engagement of the end of the" closure plate opposite the bifurcated end, said abutment, as shown inFigure 9, being formed from a-rod with the ends bent at aright angle and adapted to engage recesses in the pipe bowl. i

To secure the closure plate mounting members against withdrawal from the recesses 19, lips 22 are stamped from and deflected laterally of the angle portions 18, the lips being arranged whereby as the angle portions 18 are inserted into the recesses 19 the lips will be sprung inward, but as the inherent tendency of the material is to move said tongues laterally they will bite into the wall of the recess by any movement of the angle portions 18 outward from the recesses 19 and thus prevent the withdrawal thereof from said re-- cesses.

with the pipe bowl.

In the use of smoking pipes, there is an accumulation of burnt products about the mouth of the pipe bowl and this accumulation may be such as to frictionally resist and interfere with the ready and easy adjustment of the closure plate should the entire surface of the mouth closing portion of the plate contact with the pipe bowl. To obviate this and reduce the contact of the closure plate with the bowl to a minimum frictional engagement with the pipe bowl, this portion of the plate is depressed, as at 23, to extend outwardly from the pipe bowl and whereby only the portions bounding said depressed portion 23 will engage To facilitate the adjusting of thegclosure plate the closure plate is provided with a finger or finger nail engaging portion shown as a nib 24 pressed outwardly from the depressed portion 23 which may be readily en- ,gaged by the nail of the thumb or finger.

It is well known due to the burning of the tobacco in smoking pipes the pipe bowl is heated to -such a high temperature that should the pipe bowl be grasped by the hand of the user it may result in injury. To effect a quickdissipationof the heat from and cooling of the pipe bowl whereby it may be readily engaged by the fingers or hand without injury thereto, the outer surface area of the pipe bowl is increased. This is effected by arranging the outer surface of the pipe bowl with laterally extending projections, and in the embodiment shown comprising concentric ribs 25 extending outwardly from the opposite ends of the pipe bowl, and the peripheral portion of the bowl opposite that engaged by the closure plate may also be provided with outwardly extending ribs.
