Improvements in or applicable to 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 weighing apparatus of the kind wherein the weight or
load is suspended from a band placed around a counterweighted rolling cylinder
and has for its object to obtain an even or steady movement of the rolling cylinder
and the pointer in connection therewith.
In carrying out our invention we arrange in the centre of the rolling cylinder
on a diametrical rib, a pin from which is movably suspended a rod provided at
its lower end with a piston capable of moving freely up and down inside a cylinder.
This cylinder which is firmly attached to the frame of the apparatus and parallel
with the path of the rolling cylinder, is filled with a suitable liquid such as
glycerine. If necessary the piston may be provided with perforations.
By the up and down movement of the rolling cylinder the rod and the piston will
be moved inside the cylinder whereby the glycerine is forced between the piston
and the cylinder wall or through the perforations in the piston, whereby the move-
ment of the rolling cylinder and pointer is rendered even and steady.
Dated this 30th day of July 1898.

Improvements in or applicable to 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 and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement:-
This invention relates to weighing apparatus of the kind wherein the weight or
load is suspended from a band placed around a counterweighted rolling cylinder
and has for its object to obtain an even or steady movement of the rolling cylinder
and of the pointer in connection therewith.
As will be seen from the accompanying drawing which illustrates weighing
apparatus made according to our invention, we arrange in the centre of the rolling
cylinder 1 on a diametrical rib 2, a pin from which is movably suspended a rod 3

page_text: provided at its lower end with a piston 4 capable of moving freely up and down
inside a cylinder 5. This cylinder, which is firmly attached to the frame of the
apparatus and parallel with the path of the rolling cylinder 1, is filled with a suit-
able liquid such as glycerine. If necessary the piston 4 may be provided with
perforations.
By the up and down movement of the rolling cylinder 1 the rod 3 and the
piston 4 will be moved inside the cylinder 5 whereby the glycerine is forced between
the piston and the cylinder wall or through the perforations in the piston, so that
the movement of the rolling cylinder and pointer is rendered even and steady.
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;
In weighing apparatus of the kind wherein the weight or load is suspended from
a band wound round a counterweighted rolling cylinder, the arrangement of rod 3,
one end of which is movably attached to a pin fixed to the centre of the rolling
cylinder and the other end to a piston 4 which may or may not be perforated and
is arranged to move in a cylinder 5 which is parallel with the path of the rolling
cylinder and is filled with a suitable thick liquid such as glycerine, substantially
as hereinbefore described and illustrated.
Dated the 3rd day of September 1898.
