THOMAS WILLIAMS the Younger of Myddelton Square in the County of
Middlesex Engineer " IMPROVEMENTS IN SELF RECORDING LEVER WEIGHING
MACHINES "
This invention has for its object the enabling lever weighing machines to record
automatically in a more simple and accurate manner than heretofore the weight of
each article or package as it is weighed thus avoiding all risk of errors on the part
of the entering clerk in entering the different weights as the machine itself
produces a permanent record of the weight of each load.
The essential feature of my said invention consists in causing the sliding weight
or weights on the weighing beam or beams after such sliding weight or weights
have been properly adjusted thereon to register or record the exact weight of the
load either by impressing printing or otherwise marking the corresponding weight
directly on a recording strip or strips of paper cardboard or other suitable material
fixed to the machine itself and marked in divisions corresponding to those of the
weighing beam or beams or to record the weight of the load indirectly by acting
upon levers so arranged as to print or mark the different weights on paper or other
suitable material either by the aid of suitable mechanical connections or by the aid
of levers and electro magnets. The said strips when so marked constitute an
accurate register or record of the weight of each article or load.
or
According to one mode of carrying out my invention wherein the record is to be
made in the machine itself, I suitably adjust on a convenient support placed
underneath above or by the side of each beam a strip or strips of paper having
lines or other marks thereon corresponding exactly to the various marks
divisions in its corresponding beam and I provide the weight with a marker or a
printing die which on the lever being caused to descend or ascend will press upon
the paper and leave an impression or mark thereon on the division corresponding
to the position of the weight on its lever. Provision is made for readily changing
each strip and substituting a fresh one after each weighing has been recorded,
either by mounting two or more strips of paper on the flat sides of a polygonal
shaped roller turning on centres so that on partially rotating the same a fresh strip

employing a pile of such strips of paper acted upon by springs so as to bring a
fresh strip forward as fast as the printed or impressed strip is removed. A
moveable stop or catch serves to prevent the accidental contact of the marker or
printing die with the paper until the weights have been properly adjusted along
their beams. Where it is required to print or otherwise mark the said records at
any distance from the machine I propose to combine with the weighing machine
one or more sets of keys or levers which are separately acted upon by the ascent or
descent of the weight or weights along with their respective weighing beams each
of the said keys or levers when so acted upon being caused by suitable mechanical
connections to act upon other levers which print or mark the exact weight upon a
plain piece of paper or other suitable material at any distance from the weighing
machine or caused to establish an electric circuit by means of conducting wires
through corresponding electro magnets which are made to operate as will be
readily understood upon suitable markers and cause them to mark or impress
the exact weight of the article or load that has been weighed on the recording
strip.
