A
Improvements in Weighing Apparatus.
We, JOHAN AUGUST STACKIG, Engineer, and OTTO CARLSON, Manufacturer, both
of 42, Luntmakaregatan, Stockholm, in the Kingdom of Sweden, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in weighing apparatus and has for its
object to provide apparatus that can be used with equal facility for weighing
heavy and light articles.
According to the invention we combine apparatus of the pendulum or eccentric-
weight or spring type with ordinary beam scales.
In a suitable arrangement for carrying out our invention we employ an
eccentric-weight balance, preferably of the kind having rolling contacts, and we
so combine the same with an ordinary beam scale that its scale-pan also forms
one of the scale-pans of the said beam scales.
-
With this construction when light articles have to be.weighed only the eccentric
weight balance is brought into use and the weight is indicated, for example by a
pointer moving over a graduated scale. If however heavier articles are to be
weighed a known weight approximately corresponding thereto is first placed
in the other scale-pan of the beam scales and the excess weight of the article
is then indicated by the eccentric weight balance.
By our invention therefore we obtain a very sensitive balance the readings of
which can be read off with facility.

Improvements in Weighing Apparatus.
We, JOHAN AUGUST STACKIG, Engineer, and OTTO CARLSON, Manufacturer, both

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:-

page_text: According to the invention we combine apparatus of the pendulum or eccentric-
weight or spring type with ordinary beam scales.
In a suitable arrangement for carrying out our invention we employ an
eccentric-weight balance, preferably of the kind having rolling contacts, and we
so combine the same with an ordinary beam scale that its scale-pan also forms
one of the scale-pans of the said beam scales.
The accompanying drawing illustrates a suitable form of weighing apparatus
made according to the invention.
The scale-pan 1 carrying the article to be weighed and forming part of the
automatic or eccentric weight balance is arranged at the same time to form one
of the scale-pans of the beam scales. as clearly shewn.
With this construction when light articles have to be weighed only the eccentric
weight balance is brought into use and the weight is indicated, for example by a
pointer 2 moving over a graduated scale 3. If, however, heavier articles are to be
weighed a known weight approximately corresponding thereto is first placed in the
other scale-pan 4 of the beam scales and the excess weight of the article is then
indicated by the eccentric weight balance.
By our invention therefore we obtain a very sensitive balance the readings of
which can be read off with facility.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. The combination with the scale-pan of an automatic eccentric weight or
similar balance preferably of the kind wherein the scale-pan is attached to a band
passing round a counterweighted roller, of a pair of beam scales in such a manner
that the balance scale-pam forms one of the scale-pans of the beam scales,
substantially as herein before described and illustrated.'
2. The manufacture and use of weighing apparatus constructed as herein before
described and illustrated in the accompanying drawing.
