HOWDLE Q 7 2,314382 TOBACCO PIPE Filed Jan. 13, 1942 James Iowd ar a Patented Mar. 30, 1943 TOBACCO PIPE James Thomas Howdle, Birmingham, England, assignor to The Parker Pipe Company Limited, Notting Hill Gate, London, England Application January 13, 1942, Serial No. 426,616 In Great Britain December 26, 1940 3 Claims.

This invention relates to tobacco pipes and it is an object of the present invention to provide a pipe having an improved form of movable cover for the bowl.

According to the present invention a bowl cover is rigidly connected with a rib or leg, the lower end of which is pivotally mounted in the material forming the pipe, the rib being adapted to enter a slot or recess in the pipe bowl in such a manner that when the cover is in position over the bowl the rib or leg is substantially concealed. The length of the rib is such that the cover can be swung clear of the bowl for filling or emptying purposes and preferably the rib is pivoted at the lower end of the bowl and the bowl is provided with an enlargement preferably at the mouthpiece side to enable a slot to be provided of suilicient depth to receive the whole width of the rib or leg with the outer edge flush with the contour of the bowl. It will be understood that if the pipe bowl is normally of suflicient thickness to receive the rib no specially formed enlargement at the mouthpiece side would be necessary.

To enable the invention to be fully understood it will now be described by reference to the accompanying drawing, in which:

Fig. 1 is a sectional elevation of a tobacco pipe bowl having one form of the invention applied thereto, and

Fig. 2 is a plan view thereof.

As shown, the pipe bowl 3 is formed with an enlargement' at the stem side 5 so that in crosssection the bowl is pear-shaped as can be seen from Fig. 2. The outer end of the enlargement 4 which forms a substantially sharp vertical edge is formed with a vertical slot 6 to receive a flat rib or leg I, the lower end of which is pivoted to the bowl on a pin 8 which passes across the slot. The upper end of the rib 'I is attached to a cover 9 which is shaped to fit the top of the bowl and to cover same completely as shown in Fig. 2 The lower end of the vertical slot 6 is substantially semi-circular in curvature and the lower end of the rib I has a corresponding curvature whereby when the cover is swung to a position covering the bowl it will be retained in that position due to the frictional engagement of the semi-circular rib end with the recess lower end. When the cover is swung into a position at substantially right angles it can be removed by a bias movement of the rib relative to the recess. The cover is provided with air holes ID.

The arrangement of the rib I in relation to the slotted enlargement 4 is such that the cover may be swung into the dotted line position shown in Fig. 1, clear of the bowl, when desired. When the cover is in the closed position over the bowl the rib l is concealed within the slot 6 with its outer edge flush with the outer edges of the slot.

The rib I may be detachably connected to the bowl in any suitable manner. As here shown the lower end of the rib is provided with a slot II which engages the pivot pin 8 so that the rib can readily be attached to and detached from the pin.

The cover may be of wood, preferably matching the pipe bowl, or of metal or any other desired material or combination of materials.

I claim:

1. A tobacco pipe bowl having in combination a movable cover, a rib connected at one end to the cover, a pivot pin in the bowl adapted to engage the other end of the rib and a recess accommodating the pivot pin and the rib, said recess having its lower end substantially semi-circular in curvature, said ribat the end adapted to engage the pivot pin being formed with a slot to receive the pin and that portion of the rib engaging the transverse wall of the recess having a curvature corresponding to the curvature of the recess lower end, the arrangement being such that when the cover is swung to a position covering the bowl it will be retained in that position and when swung into a position at substantially right angles it can be removed by a bias movement of the rib relative to the recess.

2. A tobacco bowl having in combination a movable cover, a rib rigidly connected at one end to the cover, a recess in the bowl to accommodate the rib, a pivot pin passing transversely through the recess and aslotted end on the rib engaging the pivot pin, the lower end of said recess and the slotted end of said rib each having a semi-circular curvature, the arrangement being such that when the cover is swung to a position covering the bowl it will be retained in that position and when swung into a position at substantially right angles it can be removed by a bias movement of the rib relative to the recess.

3. In a device of the character described, com prising a bowl having a vertically disposed tobacco receptacle with an open top, a recess extending vertically along the inner 'face of the bowl, the lower end of said recess being semi-circular in curvature, a pivot pin extending transversely across the lower end of said recess, a rib having a cover connected thereto at its upper end, and hook means on the lower end of said rib adapted to engage the pivot pin, the lower end of said rib having a curvature corresponding to the curvature of the recess lower end whereby when the cover is swung into a position covering thebowl it will be retained in that position with the rib concealed in the recess and when swung into a position at substantially right angles it can be pivoted clear of the bowl and removed if desired by a bias movement of the rib relative to the recess.
