Improvements in Weighing Machines and Counting Apparatus
appertaining to same.
JOHN GREENWOOD and THOMAS GREENWOOD, Weighing Machine Makers
Barrow Street, Oldfield Road, Salford, in the County of Lancaster do hereby
declare the nature of this invention to be as follows:-
...
We will describe our invention as applied to a compound lever self indicator
weighing machine.
The construction of which obviates the use of either water, springs or rack and
pinion which has hithertofore been a detriment to the working of self indicating
weighing machines, also the same to register the number of loads weighed each day
week or any other length of time as the user may think fit.
This invention relates to that class of machines known as self indicating or
automatic weighing machines, the transfer lever of which is connected by a rod to
the pendulous lever from the bottom of which the finger indicating the weight
placed on the platform is given, also one arm of the said pendulous lever is con-
nected to a pair of bellows containing air in order to check the vibration of the said
index finger.
The counting apparatus we connect by an arrangement of lever or levers, and
short rod or rods to the said connecting rod of the said machine, which combined,
move in a rotary manner the index by which the number of loads weighed on the
platform are indicated.
This latter arrangement we would state is also applicable to other compound
lever weighing machines, or even ordinary scale beams.

COMPLETE SPECIFICATION.
Improvements in Weighing Machines and Counting Apparatus
appertaining to same.
We JOHN GREENWOOD and THOMAS GREENWOOD of Barrow Street, Oldfield
Road Salford in the County of Lancaster Weighing Machine Manufacturers 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:-
The object of this invention is to dispense with the rack, pinion & water, &
simply to obtain the rapidity of action of the index finger & also to ascertain the
number of loads weighed in a given time by the attaching of a counting apparatus
to that class of weighing machines known as self indicating or automatic.
The transfer lever of which is connected by a rod to the pendulous lever at the
bottom of which the finger indicating the weight placed on the platform is attached,
also one arm of the said pendulous lever is connected to a pair of bellows containing
air in order to check the vibration of the said index finger.
The counting apparatus we connect by an arrangement of lever or levers, and
short rod or rods to the said connecting roa of the said machine, which combined
move in a rotary manner the index by which the number of loads weighed on the
platform are registered, this latter arrangement we would state is also applicable to
other compound lever weighing machines or even ordinary scale beams.

page_text: On the drawings appended hereunto Fig. 1 Sheet 1 a transfer lever is connected
by a rod A to the pendulous lever from the bottom of which the finger B indicating
the weight placed on the platform is given, on the index plate also one arm C of
the said pendulous lever is connected to a pair of bellows D containing air with an
adjustable tap or valve E, by which the passage of air to and from the bellows may
be regulated, thus checking the vibration of the index finger B. The counting
apparatus Figs. 1. 2 & 3 Sheet 1 we connect by system of lever or levers F and
short rod or rods to the said connecting rod A of the said machine which combined
move in a rotary manner the index G by which the number of loads weighed on the
platform are indicated.
The arrangement of levers F Figs. 1. 2. & 3 Sheet 2 are attached to the
suspension rod A. and by means of the aforesaid lever or levers the number of loads
are indicated on counter G.
Having now particularly described and ascertained the nature of our said inven
tion and in what manner the same is to be performed we declare that what we
claim is :-
First In self indicating weighing machines the connecting of a pair of
bellows D for checking the vibration of the index finger B.
Second-In self indicating compound lever and other weighing machines the
combination and arrangement of lever or levers, rod or rods which move in a rotary
manner the index G. "
Third: Connecting the index G to the suspension rod of any kind of weighing
machines substantially as herein described and illustrated.
