COMPLETE SPECIFICATION.
Combined Weight and Cost Indicating Apparatus for Spring
Balance Scales.
We "THE COMBINED WEIGHT AND COST INDICATING SCALE COMPANY
LIMITED" of 234 High Street Christchurch, in the Provincial District of
Canterbury in the Colony of New Zealand, and HERBERT JAMES WOOD,
Grocer, and WILLIAM THOMSON, Baker, both of 71 Cathedral Christchurch,
aforesaid 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 provide an apparatus for use upon what are
known as "circular spring balances" which will indicate, in addition to the weight
of an article, the cost thereof at pre-determined prices per ounce, pound, or
otherwise, as may be arranged to suit different trades.
It consists of a circular disc, the inner surface of which is marked as an ordinary
spring balance dial, while the outer portion is divided by concentric lines, forming
as many annular rings as there are articles of different price, per unit of weight, to
be dealt with.
Radial lines extend outwardly from the ordinary weight divisions of the scale
dial, and divide the annular rings into spaces, each of which is marked with
a figure or figures so arranged that when the ordinary scale dial hand indicates the
weight, it also points to a radial column of figures indicating the cost of an article
of that weight at different prices.
An indicator fixed to, and moving with, the dial hand enables the price per unit
of weight, to which each of the annular rings is devoted, to be seen at a glance.
We will now more particularly describe our invention and the operation thereof
by the aid of the accompanying drawing which represents a spring balance scale
fitted with our apparatus for indicating the weight and cost of any article up to five
pounds weight, at from six pence to eight pence per pound.
The inner dial (a) is marked as an ordinary spring balance dial with pounds,
from one to five, the space between each pound being divided into sixteen parts
representing ounces.
The outer portion of the dial is marked concentrically, so as to form five annular
rings, each of which is devoted to articles of different price per pound, commencing
with six pence on the inner, and advancing by halfpence to eight pence in the
outermost ring.
.
The weight dividing lines are extended circumferentially so as to pass through
the annular rings and form radial columns, and figures placed in each column
represent the cost of the article, the weight of which is shown, by the pointer in the
ordinary way, at the prices to which the aunular rings are devoted.
Only a sufficient number of the cost markings are shown upon the drawing
to illustrate the invention.
An indicator (b) fixed to, and travelling with the pointer (á), and also the radial
column (c) of the dial, bear numbers corresponding with the prices applied to cach
of the annular rings, so that the ring bearing the cost of an article at a certain
price per pound is easily identified.
The illustration shows a weight of 1 lb. 11 oz. on the scale pan, the weight being
indicated by the pointer (á) while the cost at different prices between six pence and
eight pence is shown in a radial coluinn through the slot in the indicator (b).

page_text: The figures and other markings may be printed, stamped, or embossed upon the
dial in any usual manner.
It will be seen that our invention might be readily adapted to a. form of spring
balance scale, in which-the pointer is stationary, and the dial revolves to indicate
the weight.
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:-
1. The combined weight and cost indicating apparatus for spring balance scales
substantially as and for the purposes herein described and illustrated in the
accompanying drawing.
2. In a combined weight and cost indicating apparatus a dial divided by
concentric lines, and also by radial lines, extending from ordinary weight divisions
with which the inner portion of the dial is marked, whereby spaces are formed,
containing the cost of articles of different weights and at different prices
substantially as and for the purposes herein described and illustrated.
3. In combination the dial divided by lines forming concentric annular rings and
au indicator such as (b) travelling with the pointer (á) and indicating the rings
devoted to articles of different price substantially as and for the purposes herein
described and illustrated in the accompanying drawing.
Dated the 26th day of May 1896.
