SMOKING PIPE Filed Sept. 22, 1959 INVENTORS W. Fu/irmanu and 7:1? Powers Patented May 13, 1941 UNITED STATES PATENT QFFICE SMOKING PIPE Warren Fuhrmann, Kearny, N. J and Thomas F. Powers, New York, N. Y.

Application September 22, 1939, Serial No. 296,008

6 Claims.

This invention relates to smoking pipes having a spherical bowl arranged with a tobacco chamber extending diametrically of the bowl with one end opening to the circumference of the bowl and the opposite end terminating within the bowl, and a hollow stem extending from the circumference of the bowl with the bore thereof communicating with the inner end of the tobacco chamber, and particularly to a cover for the mouth or opening of the tobacco chamber to permit smoking outdoors and. prevent spilling the tobacco from the bowl while or after smoking.

It is the principal object of the invention to provide a cover for the mouth of the tobacco chamber of a spherical pipe bowl which may readily be removed from the pipe bowl and adapted to be yieldingly retained and be adjusted to any position on the pipe bowl without the aid of securing means fixed to the pipe bowl.

In the drawing accompanying and forming a part of this application, Figure 1 is a plan view looking at the top of the pipe and showing the cover in position to close the tobacco chamber In carrying out the embodiment of invention illustrated in the accompanying drawing, there is provided a smoking pipe having a spherical bowl 5 provided with a tobacco chamber extending diametrically of the bowl with one end opening to the circumference of the bowl and the 0pposite end terminating within the bowl adjacent the diametrically opposite circumference of the bowl, as shown in dotted lines at 6 in Figure 2. The spherical bowl 5 is also arranged with an integral hollow stem I extending from the bowl at a right angle to and in line with the inner end of the tobacco chamber 6 and having the bore thereof communicating with said end of the tobacco chamber, as shown in dotted lines at 8 in Figure 2. The free end of the stem 1 is adapted for the removable engagement of a mouth piece 9 in the usual manner.

It is the principal object of the invention to provide an adjustable cover for the mouth of the tobacco chamber which will permit the placing adjusted about the pipe bowl.

of the pipe in a pocket of the apparel of the 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. This object is accomplished by a cover of suitable material, such as metal or plastic composition, comprising a circular plate portion ll] having an area greater than the mouth of the tobacco chamber 6 and of arcuate or curved shape in cross section conforming to the curvature of the pipe bowl to snugly fit the mouth of the tobacco chamber and prevent the spilling of the tobacco or tobacco ash from said mouth. The circular plate It] is arranged with a plurality of circular series of perforations II to permit the entrance of air into the tobacco chamber 6 when the plate is positioned over the mouth of said chamber.

The cover plate in is yieldingly retained on the pipe bowl 5 and adapted to be adjusted in any position on the pipe bowl by a plurality of leg portions I2 integral with the plate l0 and equidistantly spaced about the periphery thereof. There are shown in the present illustration of the invention three leg portions, but the number of leg portions may be varied depending upon the diameter of the pipe bowl and the cover plate. The leg portions 12 extend from the periphery of the plate portion It) in an arcuate or curved direction, the curve being in the arc of said plate portion and conforming to the curvature of the pipe bowl 5, so that thecover plate l0 and leg portions 12 may be engaged on and be To facilitate said engagement and adjustment of the cover on the pipe bowl, the leg portions are also of arcuate or curved shape in cross section corresponding to the curvature of the plate portion and the pipe bowl, as shown at 13 in Figure l; The cover plate It] is yieldingly retained on the pipe bowl by providing the length of the leg portions of greater dimension than the radius of the pipe bowl, so that the end sections of the leg portions are positioned beyond the center axis of the pipe bowl extending parallelly of the cover plate portion, as shown at M in Figure 3. The length of the leg portions is measured from the center of the plate portion ID to the free ends of the leg portions and this length is greater than the radius of the pipe bowl. The inherent resiliency of the material of the leg portions l2 will cause said leg portions to grip the pipe bowl and permit the bottom portion of the pipe bowl in diametrically opposed relation to the mouth of the tobacco bowl 6, and in this position, the cover plate portion ID will support the pipe in upright position on a suitable support, such as a table, by the uneven surface of the cover formed by the perforations I l in the cover plate portion.

To facilitate the forming of the leg portions. 1 2, the entire cover is constructed from a spherical shell having an inner diameter slightly greater than the outer diameter of the pipe. bowl. The shell is severed parallelly and on one sideofthe diametric axis thereof and equidistantly spaced arcuate portions are severed inwardly from the peripheral! edge of the larger severed section of theshell' a distance to, form the leg portions l2 and the plate portion H) of the cover.

Having thus described our invention, we claim: i

1. In a smoking pipe, a spherical bowl arrange'dwitha tobacco chamber having a mouth opening to the circumference of the bowl, and a cover for the mouth of the bowl chamber having an arcuate portion conforming to the curvature of the bowl and a plurality of leg portions extending from the arcuate portion in the arc of said portion for the entire length of said leg portions, whereby the leg portionswill slidably grip the pipe bowl to retain the arcuate portion on the pipe bowl and permit adjustment of said arcuate portion over and in angular relation to the mouth of the bowl chamber with the under surface of said arcuate portion in contact with the bowl.

2. In a smoking pipe, a spherical bowl having a tobacco chamber extending diametrically of the bowl with one end opening to the circumference of the bowl and the opposite end'terminating within the bowl, and a cover for the opening of the bowl chamber having an arcuate portion conforming to the curvature of the bowl and of greater area than the mouth of the bowl chamber and a plurality of leg portions equidistantly spaced about the arcuate port-ion and extending from and in an arc of saidportion for the entire length of said leg portions to sli'dably grip the pipe bowl and retain the arcuate portion in adjusted positions over and in angular relation to the opening of the bowl chamber with the under surface of said arcuate portion in contact with the bowl when the arcuate portion is positioned in angular relation to the opening.
