PROVISIONAL SPECIFICATION.
An Improved Air Tight Lid or Cover for Tobacco Jars.
THOMAS BROOKE, JOHN BROOKE and ARTHUR GEORGE LEVICK of No. 66
West Street Sheffield, in the County of York Merchants do hereby declare the
nature of this invention to be as follows:-
The object of our invention is to produce a simple and effective fastener,
whereby the lids or covers of tobacco jars can be attached & made air tight, and
we accomplish this desirable object in the following manner, viz., In the outside rim
of the article to be covered we form two or more grooves with suitable gradients.
On the lid or cover of the article we form or attach two or more clips or grips of
a suitable shape & size to fit into the corresponding grooves of the article to be
covered & affix a washer of a suitable material to the underside of the lid. When
placed in position a slight twist or screw movement will tighten the lid on the
article thus making a perfectly secure & air tight lid or cover. By a reverse
movement the lid or cover is instantly unfastened.
This arrangement could be reversed by fixing or shaping the clips or grips on
the body of the article instead of the lid.

what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
On the outside rim of the article to be covered we form two or more projections
of a suitable gradient. On the lid or cover of the article we attach two or more
grips of a suitable shape and size, to catch underneath the corresponding projections
on the article to be covered-and place a washer of rubber, or any other suitable
material for forming an airtight joint, on the under part of the lid-When placed
in position a slight twist or screw movement will tighten the lid on the article, thus
making a perfectly secure and airtight lid or covering-By a reverse movement the
lid or cover is instantly unfastened.
Having explained the manner in which the jar is made airtight we will proceed
to describe its construction.
Fig. 1. A is the lid of the jar with two square holes in the outer rim shewn by
the dotted lines. B is a metal part used as a grip with a square hole in it shewn
by the dotted lines, C is a knob with a thread cut inside to receive the screw at
