PROVISIONAL SPECIFICATION.
.:
I, ALBERT LIEBES ALTMAN, trading as Albert L. Altman and Company, of
5, Pembroke Quay, Dublin, Salt Merchant, Refiner, and Salt Box Manufacturer,
do hereby declare the nature of my said invention for "IMPROVEMENTS IN THE
MANUFACTURE OF CIRCULAR 'DRUM' BOXES FOR SALT," to be as follows:-
This invention lias reference to the manufacture of circular "drum" boxes for
salt.
Boxes of this kind, as hitherto used, are made of sliced timber, and the edges
are joined together with glue.
Salt contained in these boxes, it is well known, is subject to deterioration, owing
to the fact that it absorbs the turpentine and other deleterious matter with which
the sliced timber is usually impregnated. Furthermore, the glue or substance
which is used to join the edges of the box is more or less affected by the action of
the salt, causing the joints to open and resulting in the destruction of the box.
My said Invention is designed to obviate these defects; and for this purpose,
I propose to use specially prepared sheets of the substance known as straw or wood
pulp, in the formation of the boxes, having first submitted such substance to a
damping process to render it more flexible for the object in view.
The edges of the box made of this material are joined together by stitching-
the pulp readily admitting of being stitched; whereas, sliced timber, owing to its
tendency to split, does not readily take stitching, and glue must, therefore, be used
for joining the edges.
Salt made up in boxes thus constructed, will retain for an indefinite period, its
natural flavor, and will be always in a wholesome condition.

This Invention has reference to the manufacture of circular drum boxes for salt.
Boxes of this kind as hitherto used, are made of sliced timber, and the edges
are joined together with glue. Salt contained in these boxes, it is well known, is
subject to deterioration, owing to the fact that it absorbs the turpentine and other 1
deleterious matter which the sliced timber is usually impregnated with. Further-
more the glue or substance which is used to join the edges of the box is more or
less affected by the chemical action of the salt, causing the joints to open, and
resulting in the destruction of the box.
My said Invention is designed to obviate these defects, and for this purpose 1
I propose to use specially prepared sheets of the substance known as straw, paper,
or wood pulp, in the formation of the boxes, having first submitted such substance
to a damping process, to render it more flexible for the object in view.
The edges of the box made of this material are joined together by stitching;
the pulp readily admitting of being stitched, whereas sliced timber owing to its 2
tendency to split, does not readily take stitching, and glue must consequently be
used for joining the edges.
The lid of the box is formed of a circular disk and band of the same material
joined round the edges by strips of calico.
Salt made up in boxes thus constructed will retain for an indefinite period its 2
natural flavor and will remain in a wholesome condition.
It will be obvious that my invention may be used with advantage for other
kindred purposes, such as, tobacco, butter, arrowroot, cornflour, violet powder, and
such like commodities.
When adopted for any of these purposes I may use a lid and bottom composed 3
of a band of tin, or other suitable metal, provided with a flange turned over on the
top, and an annular groove immediately underneath for the reception of a circular
disk of the pulp above specified, which is pressed home by suitable means, thus
forming a complete lid or bottom capable of ready application to the cylinder
forming the sides of the box.

Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed I declare that what
I claim is
The use and construction of 'circular “drum" boxes' in the manner, and for the
purpose substantially as described and set forth,
