13 Claims. (Cl. ZZZ-55)
My invention is concerned with a dispensing machine
operating on volumetric principle and having measuring
chambers being adapted to be adjusted automatically by
a control measuring device in accordance with the vary
ing ?lling material from said distributor plate and ?lling
it into said control measuring chamber.
Still another object of my invention is to obtain uni
formity in the conditions of charging of the control meas
uring chamber; to this aim said conveyor device of said
control measuring device can comprise at least one radially
arranged wiper plate means being rotatable in a housing
in a horizontal plane so that the path of travel thereof
overlaps said distributor plate and covers an upper open
ing of said control measuring chamber.
Furthermore, my invention resides in the features of

which results therefrom, and that the regulation of the
measuring chambers is defective because the measuring
and evaluation in accordance with the weight does not
take place until a speci?c time after dispensation.
It has been furthermore known to arrange the control
measuring device in advance of the measuring out cham
bers, in, such a Way that test samples of charged material
can be taken, at regular intervals of time, from the feed
channel leading to the measuring chambers by means of
a further volumetric measuring out device, and can be —
weighed by means. of a weigher, the latter then controlling
in turn the regulation of the measuring out chambers.
Even in this case completely satisfactory results cannot
be obtained since the charged weight, which, as is known,

The evaluation of the weighing results can be executed
by different ways: on the one hand in using each control

motor 34 is located on the frame 33 of the machine and
