PROVISIONAL SPECIFICATION.
Improvements in Plugs for Tobacco Pipes.
I THOMAS COLLIER 27 Hudson Street, Nottingham, Warehouseman, do hereby
declare the nature of this invention to be as follows:-
I make my improved plugs of pipe clay or fire clay, baked, or of wood, meershaum,
silver or other suitable metal or material, the lower exterior surface of each plug.
approximates in shape to the bottom of the interior of the pipe bowl, in which it
may be used, the upper surface of each plug is depressed so as to form a cup shaped
plug, the side of which is perforated, the oater end of each perforation terminates in
a curved groove, these grooves are connected and form a passage for the smoke from
the tobacco above the plug to the stem of the pipe when in use.
Plugs constructed as above described when placed in the bowls of tobacco pipes
effectually prevent the nicotine and ash from entering the stems.

Figures 3 and 4 are side views showing the perforations and grooves hereafter
referred to.
1 make each plug of pipe clay, or fire clay, baked, or of wood, meerschaum, silver
or other suitable metal or material, the exterior surface of each plug approximates in
shape to the bottom of the interior of the pipe bowl in which it may be used, the top
of each plug is depressed so as to form a cup, in one side of which four perforations A
are made, the outer end of each perforation terminates in a curved groove or grooves B,
on the exterior front of the plug as shown at Figure 3, the three grooves to the right
are curved towards each other until they meet in the groove B' and the three grooves
to the left are curved towards each other until they meet in the groove B³, the
grooves B1 and B2 are curved downwards towards each other until they join at B³ at
the back of the plug.
When in use a plug so constructed is placed in the bowl of a tobacco pipe, with the
lower joined ends B³ of the grooves nearest to the hole in the stem of the pipe, the
tobacco is then placed above the plug, and when lit the smoke will be drawn through
the four perforations in the plug and pass along the grooves to the hole in the stem
of the pipe.
The plug preventing the n' otine and ash from entering the stem of the pipe.
