Improvements in or relating to Boxes for Containing and
Distributing Pulverulent Material.
I, CARL OESTERFIELD of Gotha Gartenstrasse No. 6 in the Empire of Germany,.
Manufacturer do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
The object of the present invention is a box for sprinkling pulverulent substances,
which at the same time can be used for keeping them and may be made of any
suitable material, such as, for instance, cardboard, sheet metal or the like. Such a
sprinkling box is represented in the accompanying drawings wherein
Fig. 1 is a vertical central section of one construction of my improved box,
Fig. 2 is a similar view of a similar box with a domed top instead of the flat top
of the preceding example, and
Fig. 3 is a plan of the box shown in Fig. 1.
It consists of two cylinders a and b, which enter one into the other telescopically,
the cylinder a being tightly closed at its lower part by a bottom c, whereas the
cylinder b has at its upper end a tightly closing removable cover e provided with a
small opening d, which can be closed by the flap pivoted in proximity to it on the
cover. At the lower end of the cylinder b there is affixed a cylinder f, made of
cloth, linen or the like, closed at its lower part by a bottom plate g and secured to
the bottom c of the cylinder a, so that the cylinder b with the cover e aud the
cylinder f form a nearly air-tight vessel. In this vessel is placed a spiral spring h,
the upper end (Fig. 2) of which encircles a stepped cylinder i flanged at i² and
secured to the inner wall of the cylinder b by means of a projection i', the lower
end of said spring resting on the bottom g of the cylinder f.
By the pressure of the spring h on the bottom g and on the flange, the
cylinders a and b will be kept as far apart as allowed by the folding cloth
cylinder f.
The cylinder bis bent in several places of its circumference, these parts
forming corrugations k k'. In these corrugations are placed elastic bands of
rubber or similar material in such manner that with one end 1° they are attached
to the inner wall of the cylinder a, the other end being secured to the outer
wall of the cylinder b, so that when these cylinders are pushed one towards the
other the bands are extended and by their subsequent contraction force the
cylinders back into their original position.
The mode of working of the apparatus is as follows;-
The vessel G consisting of the cylinders b and f and bottom g is filled through
the cover e with the powder to be sprinkled. When the cylinders a and b are
brought nearer together by pressing on them by the fingers, the volume of the
vessel G is reduced and the air contained therein escapes with considerable force
through the opening d whereby the powder is forced out with the air and
distributed in fine particles.
In this operation the spring his compressed and the elastic bands / extended
so that when the hand pressure on the vessel ceases, the expanding of the spring has
well as the contraction of the bands
position. If desired, instead of using
the other may be dispensed with, the
spring alone or with the bands alone.
bring the cylinders again into their original
both the spring and the bauds 1, one or
device operating sufficiently well with the

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is ;-
1. A box for sprinkling pulverulent substances consisting of two vessels
telescopically entering each other and closed at one end from which the air com-
pressed by finger-pressure on the vessels escapes through a small opening, which
can be closed in the cover of one of the cylinders and forces out the powder the
two cylinders being brought into their original position after the pressure has
ceased either by a spiral spring or elastic bands or by the two together.
2. The combination and arrangement of parts constituting a complete sprinkler-
box substantially as and for the
described and illustrated in the
accompanying drawings.
