11 Claims.

This invention relates to smoking pipes having a bowl arranged with a tobacco chamber having a mouth at one end of the bowl and a stem at the opposite end of the bowl having a bore com- 5 municating with the chamber, and it is the primary object of the invention to provide closure means for the chamber mouth adjustably mounted on the bowl to be positioned juxtaposed to the exterior wall of the bowl to permit filling of the chamber with tobacco, and after the tobacco has been lighted adapted to be positioned over the mouth to close the same and prevent the lighted tobacco leaving the chamber while smoking or after smoking.

It is another object of the invention to pro* vide closure means for a smoking pipe whereby the closure means may be positioned from the chamber mouth to act as a wind shield while lighting the tobacco in the chamber.

It is a further object of the invention toprovide the closure means with a portion which will remain cool while the closure means is in closed position and the pipe is being smoked, so that the fingers of the smoker will not be burned if said portion of the closure means is touched by the fingers.

It is a still further object of the invention to arrange closure means for the mouth of a pipe chamber with manipulating means remote from the closure means whereby the closure means may be actuated from the mouth during the smok of the pipe without burning" or injuring the fingers of the smoker.

Further objects and advantages of the invention will hereinafter appear in the detailed description of the invention. 4

In carrying out the embodiment of the invention illustrated in the drawing, there is provided a smoking pipe having a bowl 8 of rectangular or square shape in cross section provided with a tobacco chamber 9 extending longitudinally of the bowl with a mouth opening to one end of the bowl and terminating adjacent the opposite end constituting the bottom of the pipe and arranged with a stem integral with the bowl and extending'laterally and centrally from a side of the bowl having a bore ll therethrough communicating with the bowl chamber 9. Chamber 9 is shown as being of circular shape in cross section,'but may be of a shape corresponding to the cross section of the bowl. The stem I0 is of square contour to harmonize with the contour of the bowl and co-operate with the bottom of the bowl to support the pipe in upright position on a fiat surface. The stem Ill is arranged at the free end for the removable engagement of a mouth piece |2- To permit of the placing of the pipe in a pocket of the apparel ofthe user with part of the tobacco which has not been consumed in the pipe bowl, or with the tobacco lighted, and prevent the soiling or burning of the pocket by the tobacco or tobacco ash spilling from the bowl chamber, or when placed elsewhere, as in a drawer with the possibility of starting a fire, adjustable closure means is provided for the mouth of the bowl chamber, comprising a' fiat plate I3 of substantially the same size and shape as the top of the bowl having a circular center portion l4 partially stamped therefrom with connecting sections I around the periphery bent from the plate to support the portion 14 in spaced relation to the body of the plate l3 and provide horizontal air passages between the center portion l4 and the plate l3, asat 16 in Figure 1. There are shown in the present instance four connecting sections l5 equidistantly spaced around the periphery of the center portion 14, but the number of said sections may vary depending on the area of air space desirable between the center portion and plate, and. the

strength of the material used for the cover plate. To further induce a draft through the tobacco in the chamber 9, the center portion I4 is arranged with air passages, shown as a plurality of perforations or holes H, but which may be a plurality of slots.

The closure plate i3 is adjustably mounted on the pipe bowl to be positioned over the mouth of bowl chamber and juxtaposed to a side wall of the bowl with the chamber mouth open to permit filling the chamber with tobacco and lighting the same. This is accomplished by a slidable member comprising a rectangular plate l8 of a. length slightly greater than the width of the side Walls of the bowl having the opposite ends flanged laterally, as at l9, and adapted to slidably engage elongated recesses in the 0D- posite side edges of a side of the pipe bowl. In the present instance, the recesses 20 are arranged in the side wall of the bowl opposite the wall integral with the stem |3, but the recesses may be arranged in and the slide plate |8 mounted on either of the side walls of the bowl adjacent the wall having the stem it. The flanged ends I9 and recesses 20 are arranged to prevent disengagement of said flanged ends from the recesses, as shown in Figure 3, by extending the recesses obliquely into the bowl and correspondingly bending the flanged ends. The flanged ends may be bent to right angular form with the free angular sections engaging slots in the recesses which are of right angle shape in cross section. One side of the slide plate is is arranged with hinge knuckles 2| spaced from the flanged ends l9 to extend into a recess 22 in an end of the closure plate l3 juxtaposed to hinge knuckles 23 arranged on said end of the closure plate at opposite ends of the recess 22, whereby the closure plate is pivoted to the slide plate by a pintle 2'4 engaged in the knuckles 2| and 23. The closure plate is yieldingly urged toward the mouth of the pipe chamber and. the bowl wall arranged with the recesses 29 by a spring 25 coiled around the pintle between the knuckles 2| with one end of the spring engaging the closure plate, as at 23, and the other end engaging the slide plate, as at 21. When the slide plate H3 is positioned adjacent the top of the pipe bowl, the closure plate will be urged by the spring 25 to engage the top of the pipe bowl and cover the mouth of the bowl chamber by the center portion M. The closure plate is removed from the top of the pipe bowl to uncover the chamber mouth by actuating the slide plate I8 toward the bottom of the pipe bowl, said actuation of the slide plate moving the closure plate over the edge of the bowl between the top and side wall arranged with the recesses 20 which will raise the free end of the closure plate and position said plate at an angle to the topof the pipe bowl, as shown in dot and dash lines in Figure l, and the continued movement of the slide plate |8 will position the clo sure plate juxtaposed to the bowl wall arranged with the recesses 23.

To facilitate the actuation of the slide plate l8, said plate is arranged with manipulating means by arranging the end of the plate opposite the knuckle end with an extension and curling said extension into a finger gripping member, as at 28. The actuating movement of the slide plate I8 is limited and said plate is prevented from being removed from the ends of the recesses 20 by abutments in the form of pins 29 fixed in the opposite ends of a recess 20, which is of greater width than the other recess, and said pins being adapted to engage a projection 30 extending from the flange l9 engaged in the recess 20 of greater width. The pins 29 are positioned in the recess of greater width out of the path of travel of the flange I9 and the projection 30 is of a length to engage the slide of said recess and prevent canting of the slide plate.

The closure plate |3 may be readily adjusted to position juxtaposed to the side wall of the pipe bowl by the slide plate I8 to permit tamping of the lighted tobacco in the bowl chamber without injuring or burning the fingers of the user, as the finger grip 28 will remain cool due to the remote position thereof from the closure plate.

The raising or spacing of the center portion M from the body of the closure plate will provide said plate with an air cooled portion which will prevent injuring or burning the fingers of the user if said center portion is accidently touched by the user. In Figures 4 to '7, there are illustrated modified forms of the closure plate to carry out this purpose of providing the closure plate with an air cooled portion.

In Figures 4 and 5, the closure plate is substantially twice the length of the plate l3 shown in Figures 1 to 3, inclusive, to provide an additional end portion 3| having air passages therein such as perforations 32 or a radial series of 0 slots. The portion 3| is folded over the upper surface of portion I3 with an intermediate portion 33 spacing the portion 3| from the portion 13 a distance to permit sufficient circulation of air between said portions l3 and 3| to maintain the plate portion 3| cool and prevent injury to the fingers of the user. The air passages 32 will also reduce the amount of heat transmitting surface of the plate portion 3|, which will aid in maintaining said portion cool. The plate portion 3| may be arched to provide a pleasing appearance and extended to about the knuckles 23 of the plate portion I3. The structure of the slide plate of the modified closure plate |3, 3|, 33 of Figures 4 and 5 is the same as shown in Figures 1 to 3, inclusive, as indicated by the reference numerals.

In Figures 6 and '7, the entire closure plate |3, l4, I5, is spaced from the top of the pipe bowl to provide a passage for air between said plate and the chamber mouth by forming the closure plate from .a blank of greater width whereby angular side portions are formed having a vertical section 34 and a horizontal section 35 extending parallelly of the plate |3 to engage the top of the pipe bowl. Said blank will .also have lateral extensions extending from the sides thereof adjacent the knuckles 23 to form horizontal portions 36 to engage the top of the pipe bowl adjacent the side arranged with the recesses 20. The free end of the closure plate |3 is extended slightly beyond the angular side portions 34, 35 and bent inwardly to form a lip 31 partly closing the space between the closure plate and the top of the pipe bowl, as shown in Figure 6, to prevent the escape of ashes from the tobacco chamber but permitting air to pass between said lip and the pipe bowl.

The center portion M of the closure plate I 3 in the Figures 6 and '7 structure is shown of arcuate shape in cross section and the center portion M of the Figures 1 to 3, inclusive, and Figures 4 and 5 structures may be of the same formation instead of being flat as shown in said figures. The space between the portion l4 and the body of the closure plate [3 is large enough to permit passage of sufiicient air to cool said center portion but too small to permit the escape of ashes from the tobacco chamber.

To facilitate the lighting of the tobacco in the pipe chamber outdoors, the slide plate I8 is adjusted to position the closure plate I3 to extend at an angle to the chamber mouth, as shown in dot and dash lines in Figure 1. The angular position of the closure plate is varied by the adjustment of the slide plate toward and away from the chamber mouth.
