PROVISIONAL SPECIFICATION.
Improved Jar for Containing and Preserving Tobacco, Drugs, and
other Articles.
ARTHUR GEORGE SULIEMAN MAHOMED 1 Beaumont Terrace Bournemouth do
hereby declare the nature of this invention to be as follows:-
A cylindrical jar is grooved on inside by two descending spirals commencing at
opposite points and each proceeding simultaneously by about two complete revolutions
to bottom. The cover or lid is a flat dise to which is attached a metal tube crossing
it diametrically. The tube is interrupted, partially at middle. It contains a rod,
broken up by two links in the middle (corresponding to interruption in tube),
they are here both attached to a handle working on an upright. By depressing
the handle the bolts are shot into grooves in side of jar, or withdrawn, so that lid is
fixed by screw-motion at any point in jar and by pulling on handle is removed
altogether.

page_text: A. If the jars are made in stoneware or other substance in which exactitude of
calibre not always to be obtained, the bolts must be made adjustable.
For this purpose a piece of india-rubber or other elastic material, is to be inserted
in the tunnel prepared for the bolt; the bolt is then inserted and kept from falling
out by a pin piercing the tunnel at right angles. The bolt must have a notch of
about an inch filed out of its thickness so that it may play about the pin; being
forced in by the narrowing calibre of jar, or forced out by the elasticity of the rubber
where the jar is larger & vice versa.
B. If used for semi fluid contents as butter, ointments, etc. the bottom of the jar
may have a stoppered-hole in it; or the whole bottom may be replaced by a lid fixed
by a bayonet joint or other arrangement, so that the descent of the lid in the grooves
may cause the contents to extrude at bottom.
C. If a perfectly air-tight jar is desired a lid with bolts must be made, and the
handle (fixed immoveably in it) must have a stem of an inch or two, on which a screw
is cut. On this screw, before fixing, must be placed another disc of similar size with
a collar, working on the screw, placed separately above it, so that the upper disc
may be screwed down upon the lower one and so cause the lateral projection of an
india-rubber ring interposed between the lid and the disc.
This action is not brought into play until the lid has been screwed down upon the
contents.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is, that
(1) Articles can by means of it be kept in their own atmosphere; for the lid
descending on the contents as they are used their is no imprisoned air; and moist
objects can be kept moist; or dry ones kept dry, better than heretofore.
(2) Objects can also be kept under the continuous pressure of the screw; air is thus
expelled from among their substance, and evaporation prevented.
