COMPLETE SPECIFICATION.
An Improved Apparatus for Measuring Predetermined Quantities of
Granular or Pulverous Materials.
We, KARL WENDE, of the Market Place Nimptsch, Clockmaker and MAX
KUDRASS, of Schleswig Strasse Münsterberg, Merchant both in the Kingdom of
Prussia, 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 present invention consists of an apparatus for the measuring of pre-
determined and variable quantities or weights of granular or pulverous materials
and comprises the details of construction, hereinafter more particularly described
and pointed out in the claims.
And in order to render the present specification more easily intelligible reference
is made to the accompanying drawing, in which similar letters of reference denote
similar parts throughout the several views.
Fig. 1 being a vertical section through the machine on the line - of Fig. 2.
Fig. 2 is a plan and Fig. 3 is a front elevation of the machine.
The machine comprises a vertical standard d, provided with means at its lower
end for clamping it to a table or counter. At its upper part the standard dis
provided with two horizontally projecting plates b and c of which the lower is
adjustable with regard to the upper on the said standard, by means of a slot in
the latter and a bracket p on the lower plate c, said bracket carrying a clamping
screw m engaging the slot of the standard at the rear of the same. Between the
plates b and c are mounted to rotate on pivot z plates e and e¹ pressed against their
respective upper and lower plates by means of a spring n.
The two plates e and e' are telescopically connected by means of any number of
tubes (in the drawing three are shown), said tubes being telescoped to allow of
the adjustment of the lower plate. The standard d is provided with a scale, on
which the bracket p is adjustable so that the tubes may be adjusted to receive
any desired quantity or weight of the granular or pulverous substance to be
measured up.
The upper of the two plates e e² is provided with projections s on its periphery
extending beyond the similarly shaped plate and enabling the plate to be
conveniently turned on its pivot.
The upper plate b is provided with an aperture corresponding to the position of
any one of the tubes / when the plates e e¹ are rotated, and above said aperture or
opening is arranged the hopper a. The lower plate el is also provided with an
outlet funnel, preferably of conical construction as at o said funnel being in the line
of rotation of the telescoped tubes, but at a different point in the said line or curve
to that at which the hopper a is attached.
The operation of the device will be obvious from the above description.
The material to be measured is placed in the hopper a the lower outlet of which
is closed, when the tube is not underneath, by the plate e. On turning the tube h
beneath the latter will be filled, and on further rotating the discs e e' another tube h
will be brought under the hopper, and the one first filled will be simultaneously
brought over the opening outlet o under which the receptacle for the substance is
held at 1. Thus on continuously rotating the discs e and e¹ the material in the
hopper may be uninterruptedly measured.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. A device for the measuring of predetermined quantities of granular or
pulverous substances consisting of the combination of au upper stationary plate, a
lower corresponding vertically adjustable plate parallel to the said upper plate, and
means for adjusting said lower plate, discs mounted to rotate between said upper
and lower plates and means for retaining the said discs against their respective
plates, a series of telescopically arranged tubes connecting said plates, said tubes
being arranged in a circle on the plates, a hopper on the upper stationary plate, an
orifice in said plate under the hopper in the line of rotation of the telescoped tubes,
and an outlet in the lower plate in a line with the line of rotation of the tubes but
at a different point in the same to that of the hopper and means for rotating said
upper and lower plates substantially as described and shown and for the purpose
specified.
2. The combination of a standard d, having an upper horizontal stationary
plate band a lower adjustable plate e discs e el mounted between said plates and
kept apart by springs, telescoped tubes h connecting said discs, and arranged in a
ring, a hopper on the upper plate having an outlet through the same in the line of
rotation of the tubes h and an outlet bole with conical funnel o in the lower plate
in the line of rotation of the said tubes, but not under the hopper, a slot in the
standard d and a bracket p on the lower plate c and a clamping screw m to clamp
said bracket to the standard substantially as described and set forth.
Dated this 12th day of November 1896.
