the Commissioners of Patents, with his Petition, on the 26th June
1875.—A communication from abroad by Paul Zimmermann, of
Brunswick, in the German Empire.
I, HENRY SIMON, of No. 7, St. Peter's Square, Manchester, in the
County of Lancaster, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN APPARATUS FOR MEASURING OUT GRANULAR OR PULVERULENT
MATERIALS AND CHARGING PACKAGES THEREWITH," to be as follows:-
:-
This Invention relates to apparatus, whereby granular or pulverulent
materials such as grains, or seeds, or powdered substance, such as flour
or cocoa can be rapidly and correctly measured out in such quantities as
may be desired, and charged into bags, cases, or other packages.
The apparatus has at its upper part a conical hopper into which a
considerable quantity of the material is charged and kept freely
descending as required by the action of knives or agitators on a
vertical shaft, which is caused to revolve within the hopper by bevil
or other suitable gearing. Below the hopper is a cylindrical receptacle
also provided with agitators, and from the bottom of this receptacle a
number of tubes lead each into a cylindrical case, which is made in two

page_text: parts, the one part sliding telescopically on the other, so that the
length of the case and consequently its capacity can be adjusted as
desired. Each of these cases is provided with a slide above, and a slide
below like the outlet of a shot belt, and the slides of the several cases
are preferably connected to levers, so that by one movement they may
all or any number of them may be closed or opened simultaneously.
Beneath the lower slides the cases terminate in conical mouth-pieces.
Under the cases is a frame which can be moved upwards or down-
wards, and set at any desired height by means of a screw. On this
frame is a horizontal shaft having on it a crank, cam, or eccentric, or a 1
pair of cranks, cams, or eccentrics, on which is mounted a table in such
a manner that by turning the shaft partly round the table can be raised
or lowered while the frame remains fixed in position. There are also on
the shaft bosses with teeth or projections on them that act on the table
when they rotate so as to give it a vertical vibratory movement.
The apparatus operates in the following manner:-The telescopic
cases being adjusted to the desired length by means of nuts or screwed
stems, which raise or lower the lower parts of the cases with their lower
slides and mouth-pieces; and the frame of the table being also adjusted
to the required height so that the boxes, bags, or other packages can be i
placed on the table one under each telescopic case, the hopper is charged
with the material and the vertical shaft is made to revolve by any
convenient power. The upper slides of the cases being opened while
the lower slides are closed, the material being kept agitated by the
revolving knives is made to charge these cases rapidly and uniformly. 2
The upper slides being then closed and the table being raised by a
partial rotation of the shaft on which it is mounted, so as to bring the
bags or other packages on it up to and so as to enclose the conical
mouth-pieces of the cases, the lower slides of the latter are opened and
the material drops from the cases into the packages, being settled down
in the latter by the vertical vibration of the table on which they stand.
The lower slides of the casing being then closed and the upper slides
opened, the table is lowered and the charged packages are removed from
it, whereupon the operation can be repeated.
When the material has to be charged in constant and in variable 8
measure, cases of fixed dimensions may be employed without the teles-

page_text: mouths of the measuring cases and their removal when filled, frames
are employed divided into compartments, each containing an empty
package in its proper position to come under a mouth-piece when the
frame is placed on the table of the machine.
The packages contained in the frame being simultaneously charged as
above described the frame with all the packages is removed bodily from
the table and another like frame with empty packages is put in its
place, so that with two or more such frames used alternately the work
of charging and packing can proceed rapidly and uninterruptedly.
