I, CHARLES INGREY A.M.I.C.E., of 47, Cannon Street, in the City of London,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to weighing apparatus in which the weight to be weighed
is supported near one end of a lever or levers the movement of the other end, due
to the weight, being imparted to mechanism having adjustable weights or springs.
According to my invention I arrange the fulcrum and the points at which the
thrust or pull of the weight is received and given off so as to be relatively adjustable.
In carrying out my invention I advantageously arrange the knife edge of the
fulcrum or either of the said points above described in a bar pivoted to the weighing
lever or levers the said bar being adjusted relatively with the said lever or levers
by a screwed stud and nuts.
An advantage of my invention in that in weighing machines provided with dials
the weighing lever or levers can be adjusted to correspond with the graduations on
the dial thereby rendering the dividing of each dial unnecessary.

I, CHARLES INGREY A.M.I.C.E., of 47, Cannon Street, in the City of London,
Engineer, 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 in which the weight to be weighed
is supported near one end of a lever or levers the movement of the other end, due
to the weight, being imparted to mechanism having adjustable weights or springs.
According to my invention I arrange the fulcrum and the points at which the
thrust or pull of the weight is received and given off so as to be relatively adjustable.
In carrying out my invention I advantageously arrange the knife edge of the
fulcrum or either of the said points above described in a movable device such as a
bar or arm pivoted to the weighing lever or levers the said bar being adjusted
relatively with the said lever or levers by a screwed stud and nuts.
An advantage of my invention is that in weighing machines provided with dials
the weighing lever or levers can be adjusted to correspond with the graduations on
the dial thereby rendering the dividing of each dial unnecessary.
To enable my invention to be fully understood I will describe the same by refer-
ence to the accompanying drawings, in which:-
Figure 1 is a sectional elevation shewing my invention applied to the recorder

page_text: weighing mechanism of the kind described in the specification of former Letters
Patent No. 22126 of 1895; and,
Figures 2 and 3 are plan views of details of the same;
Figures 4 and 5 are respectively a sectional elevation and a plan shewing the
application of my invention to a weighing machine of the kind known as the
automatic coin-freed weighing machine.
a is the box or casing of the recorder, is a rod connected with the weigh beam
and designed to move in an upward direction under the action of the scale when
weighing and c, d are the levers through which the movement of the rod bis
transmitted.
e is the knife edge fulcrum of the lever d which as shewn is suspended by a
link and g is the knife edge through which the motion of the lever c is trans-
mmitted to the lever d by means of the link g'. The knife edge fulcrum e is carried
by a movable device, such as an arm k pivoted at its lower end to the lever d in
such a manner that the distance between the knife edges and e can be varied. i is
a screw which serves for moving the arm h and adjusting it in any desired position.
It will be obvious that by diminishing or increasing the distance between the
two knife edges e and g a given movement of the lever c will impart a greater or
less amount of movement to the free end of the lever d to which the recorder rod
is attached or connected.
b is a bracket forming a support for one end of the lever c when in operation.
In the arrangement of my invention shewn in Figures 4 and 5 the pivoted arm h
is arranged at the free end of the longer of the two weighing levers j, k forming a
compound weighing lever of ordinary construction the lever being suspended from
the framing of the machine by the links, whilst the lever is suspended from
the framing by links m, m and from the lever by another link n, the platform o
being carried by knife edges p, p upon the said compound lever.
With this arrangement of compound lever the knife edge y at the free end of the
lever and to which the rod r extending to the indicating mechanism is connected
moves through a greater or less are according to the weight upon the platform. It
will be obvious that by adjusting the arm by means of the screw the distance
between the fulcrums of the said compound lever and the knife edge y can be
increased or diminished whereby a given downward movement on the platform will
impart a greater or less amount of movement to the indicating mechanism in
connection with the rod r.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. In weighing apparatus the combination with the weighing lever from which
motion is communicated to the indicating or recording mechanism, of a movable
device carrying one of the knife edges of the said lever and adapted to be adjusted
for the purpose of varying the distance between the fulcrum of the said lever and
the said knife edge, substantially as described.
2. The combination with one of the weighing levers of a weighing machine
of an arm such as h, constructed, arranged and operating substantially in the
manner hereinbefore described and illustrated in the accompanying drawings for
the purpose specified.
