An Improved Separator for use in connection with Granulated
Substances, Liquids, and the like.
I, RUDOLPH HENDRIK JOHAN GALLANDAT HUET, of Haarlem, Holland, Manufac-
turer of Silk Gauze and Silk, Bolting Cloth, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly de-
scribed and ascertained in and by the following statement:-
My invention relates to an improved separator for use in connection with granu-
lated substances, liquids, and the like, and has for its object to provide means
whereby same is effected in a very simple, inexpensive, and efficacious manner.
In order that my invention may the better be understood, I have appended the
accompanying sheet of drawings, in which Figure 1 is a front elevational view
of my improved device, Figure 2, a section of same, and Figure 3, a plan view
with the cap (hereinafter referred to) removed.
Like letters of reference indicate like and corresponding parts throughout the
several views.
In accordance with my invention, I employ a receptacle such as a of any suit-
able size and shape, and place within the top of same a small ring or band b. I
also employ a small cylinder or tube c and place over one end of same a sieve d,
composed of silk gauze or the like of any desired mesh. Said sieve d is held taut
and securely upon the cylinder c by reason of the latter being placed within the
top of the above referred to ring 6. Over the top of the cylinder I place the
cap or cover e secured thereto by any suitable means.
When it is desired to separate a mixture of granulated substances composed of
several ingredients of different sizes in order to ascertain the nature and sizes of
the several ingredients, I place upon the cylinder c a sieve with a large mesh,
and connect the several segments together as shown. I then place upon the sieve
a portion of the substances to be treated. The cap e is then placed over the top
of the cylinder c and the whole device is given a gentle shaking, when it will be
found that the smaller ingredients will fall through the sieve into the receptacle a
whilst the larger ingredients will remain upon the sieve. After this operation
is completed, the cylinder c and sieve are removed, and the larger ingredients
placed in any convenient receptacle by the operator for treatment. The sieve
is then changed for one of a finer mesh, and the ingredients that passed into the
receptacle are placed upon said sieve after the device has been built up again.
The same operation of shaking is then given the device, when the next size of the
ingredients is obtained. The arrangement of changing the sieves, and the opera-
tion for obtaining the various sizes of the ingredients is carried out until the ingre-
dients to be treated are exhausted, whence it will be found that all the various sizes
of the ingredients are obtained, which will materially add to the purposes of
analyzing or for obtaining such for instance in chemical substances the exact
number of grains of a certain sized ingredient that weigh a certain weight.
Although I have described my invention as being used in connection with solid
substances, still the same can if desired be availed of with equal facility for use

page_text: in convection with liquids when required to be separated for analytical or other
purposes, as the thicker liquids will remain upon the various sieves.
My-device may be made of any suitable' material such for instance as vulcanite,
and also can be made in any suitable size and shape.
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 improved separator for use in connection with granulated substances, liquids
and the like, substantially-as and for the purposes herein described and shown in
the accompanying sheet of drawings.
