page_text: 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 of the kind
wherein the weight or load is suspended from a band placed round a counterweighted"
rolling cylinder, and consists in a device for transmitting the movement of the
cylinder to the pointer in such a manner that the pointer always moves uniform
distances proportionate with the increase of the load, which is a feature of the
greatest importance.
In carrying out our invention we fix to the centre of the rolling cylinder a pin
carrying a movable lever the free end of which is movably connected with one arm
of an angle lever having its fulcrum arranged on the frame of the weighing
apparatus. One arm of the said angle lever carries a toothed segment engaging
with a pinion to which a pointer is attached. It is evident that by the movement
of the rolling cylinder the movable lever will turn the angle lever upon its
fulcrum and thus transmit the movement of the said cylinder to the pointer by
means of the segment and pinion.
By suitably arranging the proportions of the various lever-arms the pointer may
be made to move perfectly uniformly for even increases of the load.
Instead of the toothed segment and pinion other suitable means for transmitting
the movement of the angle lever arm to the pointer may be employed, such for
instance as friction rollers, cord pulley with the cord attached to a segment or the
like. The same result may also be obtained by attaching the pointer direct to the
angle lever arm whereby the pointer will move together with the said arm but its
movement to both sides will then be limited to a certain extent.

This invention relates to improvements in weighing apparatus of the kind
wherein the weight or load is suspended from a band placed round a counter-
weighted rolling cylinder, and consists in a device for transmitting the movement
of the cylinder to the pointer in-such a manner that the pointer always moves
through uniform distances proportionate with the increase of the load, which is a
feature of the greatest importance.
As shewn in the accompanying drawing, which illustrates weighing apparatus
made according to the invention we fix to the centre of the rolling cylinder 1,
which is formed with diametrical rib 2, a pin carrying a movable lever 3 the free
end of which is movably connected with one arm 4 of an angle or bent lever 4,
5 having its fulcrum arranged on the frame of the weighing apparatus. The arm 5
of the said bent lever carries a toothed segment 6 engaging with a pinion 7 to
which a pointer 8 is attached. It is evident that by the movement of the rolling
cylinder the lever 3 will turn the bent lever 4, 5 upon its fulcrum and thus trans-
mit the movement of the said cylinder 1 to the pointér 8 by means of the segment G
and pinion 7.
By suitably arranging the proportions of the various lever-arms the pointer 8
may be made to move perfectly uniformly for even increments of the load.
Instead of the toothed segment 6 and pinion 7 other suitable means for trans-
mitting the movement of the bent lever arm 4, 5 to the pointer 8 may be employed,
such for instance as friction rollers, a cord-pulley with the cord attached to a
segment or the like. The same result may also be obtained by attaching the pointer
direct to the angle lever arm whereby the said pointer will move together with
the said arm although its movement to both sides will then be limited to a certain
extent.
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. In automatic weighing apparatus of the kind wherein the weight or load is
suspended from a band placed round a counterweighted rolling cylinder, the
arrangement of lever 3, one end of which can move upon a pin fixed to the centre
of the rolling cylinder and the other end of which is movably connected to the arm 4
of an angle or bent lever 4, 5 pivoting upon a fulcrum secured to the frame of the
apparatus, the other arm 5 of the said lever transmitting its movement through
suitable gear to the pointer 8, of the apparatus substantially as hereinbefore
described and illustrated.
2. In automatic weighing apparatus of the kind described in Claim 1, attaching
the pointer 8 directly to the arm 5 of the lever 4, 5 substantially as hercinbefore
described and illustrated.
