Improved Cost Indicating, Registering, and Weight Totalling
Apparatus for Employment upon Weighing Machines.
We, WILLIAM HICKLEY GUNDRY, Auditor, and WILLIAM LEONARD DEIGIITON
GUNDRY, Bank Clerk, both of 183, Hereford Street, Christchurch, in the Pro-
vincial District of Canterbury, in the Colony of New Zealand, 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 provides apparatus for employment upon or in connection with
lever platform weighing machines to indicate the cost of an article weighed upon
the scale at any one of a number of pre-determined prices per unit of weight.
The cost of every article weighed is also recorded upon a travelling band of
paper and totalling mechanism is actuated which indicates the total weight of
articles weighed upon the machine at one or a plurality of weighings.
The cost indicating apparatus consists of a disc dial revolvable behind a fixed
screen and bearing upon its face a number of radial columns of figures, the
figures in each column representing the cost of articles of one weight at
different prices.
The dial is revolved by mechanism from the weighing bob upon the lever
arm of the weighing machine and when an article is weighed the radial columın
of cost markings representing the cost of articles of that weight at different prices
per unit is brought into a vertical position above the axis of the dial and in
line with a slot cut in the screen referred to.
A cover plate caused to slide over the vertical column of figures has an aper-
ture through which only one cost marking is visible at a time and the cover
plate is held when this aperture is in correct position by one of a number of
horizontal bolts placed one above the other and either or which may be operated
to engage a projection upon the cover plate.
In the recording mechanism the back of the dial has figure markings in bas
relief corresponding exactly with the figures upon its face this result being
preferably obtained by stamping the figures so that they appear in recess upon
the face and in relief upon the back.
A travelling band of paper is pressed by a roller against the figures at the
back of the dial corresponding with those seen through the aperture in the
cover plate upon its face the paper being marked by a carbon or ink ribbon
interposed between it and the figures.
The weight totalling mechanism consists of an ordinary counter which is
driven by a spur wheel upon the dial axle a toothed pinion wheel of the counter
being brought into gear with the spur wheel after each weighing operation as
herein described.
We will more particularly describe our invention and the operation thereof
by the aid of the accompanying drawings wherein :-

We will first describe the cost indicating mechanism with reference more
particularly to Figures 1 to 4, 12, 13, and 18 and 19 of the drawings.
The weighing machine weighing bob (1) upon the lever arm both shown in
dotted lines in Figure 1 has an are shaped recess (r) which receives a pin (2)
projecting from a slide block (3) said slide block being movable horizontally in
guides (4) and the recess in the balance bob shaped to allow the lever of the
weighing machine to vibrate during a weighing operation, while horizontal
movement of the weighing bob is communicated to the slide block.
A driving band (5) formed of ribbon steel is connected at each end to opposite
ends of the slide block and after passing over guide pulleys (6) is led over a
sprocket wheel (7) which has sprockets upon its periphery taking into corre-
sponding perforations in the driving band, see Figure 1.
Sprocket wheel (7) is fixed upon a spindle (8) journalled in bracket (9) Fig. 3
and said spindle has also a sprocket wheel (10) fixed upon it connected. by a
driving band (11), similar to that described, with a sprocket wheel (12) fixed
upon an axle (13) which carries the disc dial (14). See Figures 1 and 3.'
The dial is provided upon its face and back with the same number of radial
columns of figures as the number of different weights the machine is calculated
to deal with.
The figures upon the face of the dial are to give visual indication only and
may be produced by printing or analogous means but the figures upon the back
of the dial are to be used as printing type and are cast in stereo-metal or india-
rubber or by stamping the dial as described in the preamble hereto so as to be
in relief, and are arranged to read backwards in the manner of printing type.
There are as many cost markings in each radial column as there are different
prices per unit of weight at which articles are sold and the figures are arranged
in regular order with the cost of an article of the lowest price nearest to the
centre of the dial the next higher price immediately beyond it and so on.
In a weighing operation when the weighing bob (1*) has been adjusted upon
the weighing machine lever to the weight upon the scale then the 'dial has been
revolved by the sprocket wheels and driving bands described until the radial
column of figures giving the cost of articles of that weight at different prices
is in a vertical position above the centre of the dial.
The dial revolves behind a fixed screen plate (15) the upper portion of which
has a vertical slot (16) over which slides a cover plate (17) having an aper-
ture (18) through which only one of the cost markings upon the dial is seen at
a time. See Fig. 6.

page_text: The aperture (18) is brought into correct position to expose the marking giving
the cost of an article being weighed at a particular price in the following
manner:-
The cover plate (17) is connected by a bridge piece (19) Figure 6 with a
plate (20) which extends down the back of the dial and is bifurcated to clear
the dial axle (13) and has brackets (21) fixed upon either side through which
pass vertical guide rods (22) Figure 3.
The cover plate tends to slide vertically by reason of a weighted plunger (23)
working in a cylinder (24) and provided with a cord (25) passing over a guide
pulley (26) and connected to a bracket (27) at the bottom of the plate (20),
Figure 3.
The cover plate (17) is retained in its normal position by a hook (28) which
engages with a bracket (29) fixed at the bottom of the cover plate said hook
being carried by a horizontal sliding bar (30) which has a number of cam
faces (31). Figures 2 and 18.
Sliding bolts (32) equal in number to the different prices used are arranged
upon the screen plate (15) the one above the other and upon each side at right
angles to the cover plate (17) cach being provided with a returning spring (33).
Figures 2 & 12.
Levers (34) one for each bolt, fulcrumed at (35) and engaging with a pin (36)
Fig. 12 upon the bolt at one end and having a bevel cam face (37) at the other,
are employed to operate one or other of the bolts and cause it to project into
the path of the bracket (29) and thereby to stop the cover plate in its vertical
travel when the aperture (18) is in correct position to disclose the cost of an
article then upon the scale at a certain price. See Figs. 2, 12 and 18.
Push buttons (38) one for each lever are each fixed upon a spindle (39) which
passes through the front of the casing (40) and a disc cam (41) at the end of
each spindle is arranged, when the button is pushed inwardly to contact with
one of the cam faces (31) and to slide the bar (30) Figs. 12 and 18 longitudinally
against the pressure of a returning spring (42) Fig. 2 and to thereby withdraw
the hook (28) from engagement with bracket (29) and allow cover plate (17) to
rise under influence of the weighted plunger (23) Fig. 3.
The cam (41) also at the same time contacts with one of the bevel cam
faces (37) and operates the lever to which it is attached to cause one of the
bolts (32) to project into the path of the bracket (29) Figs. 2 and 18.
The push buttons are each marked with the particular price per unit of weight
to correspond with the cost marking exposed when it is operated, a spring (43)
coiled around each of the spindles (39) between the casing of the apparatus and
the push button ensures their return after an operation. See Fig. 18.
The end of each bolt is provided with a notch (44) Fig. 12 into which a pro-
jection upon bracket (29) Fig. 12 passes and prevents the bolt from passing
back until the cover plate (17) has been brought down in a manner to be
described.
To prevent the possibility of a push button being operated so quickly that its
bolt returns from the path of the bracket (29) before said bracket engages with
it, locking plates (45) shown clearly in Figures 12 and 13 are employed which
have holes corresponding with the number and diameter of the bolts and at the
same distance apart.
The locking plates are connected together at their lower ends by a bracket (46)
and tend to slide each over the face of the metal bars (47) through which the
bolts operate. a spring (48) pressing upwardly, upon bracket (46) Fig. 12.
Normally the locking plates are held down, so that the holes are opposite te
the bolt holes, by the bottom of the cover plate (17) but when a push button
is operated the rise of the cover plate permits the plates (45) to slide upwardly
a short distance and the locking plate upon the lower side of the hole through
which an operated bolt has passed engages in a notch (49) with which each of

page_text: the bolts is provided and prevents its return until the locking plates are depressed
by the return of the cover plate (17) to its normal position Figure 12.
We will now describe the arrangement for returning the dial disc and the.
cover plate (17) to their zero positions after the apparatus has been operated,
referring more particularly to Figures 5, and 20.
Upon the dial axle (13) is a drum (50) upon which a cord (51) is wound by
the forward revolution of the dial under a weighing operation.
The cord is carried round the tension pulley (52) which has a weight (53)
attached to it, and is then led over the guide pulley (54) and connected to a
weighted plunger (55) working in the cylinder (56).
The plunger has a piston leather (57) at its lower end and a tap (58) near the
bottom of the cylinder permits air to be compressed beneath the piston leather
and the rate of descent of the plunger to be thereby regulated. An air admission
valve (59) at the base of the cylinder allows air to pass in when the plunger is
lifted.
A spring catch (60) upon the top of the cylinder engages in a notch (61) in
the plunger when it is at the top of its stroke.
A hand lever (62) pivoted on a bracket (62") see Figure 3 upon the casing of
the apparatus extends across the face of the dial and has a_ short projecting
arm (63) which passes round and extends along the back of the dial parallel
with said lever. See Figure 4.
A weight (64) attached to a cord (65) passing over the pulley (66) and con-
nected to the lever (62) acts as a counter balance for said lever.
The plunger (55) has a pivoted upwardly extending lifting rod (68) passing
through a bracket (63) upon the arm (64) referred to and terminating with a
nut (69). See Figure 3.
The plunger is prevented from turning in the cylinder by a rod (70) working
through a fixed guide (71) Figure 3.
The spring catch (60) has a tail piece (72) arranged to be engaged by a
pin (73) projecting from the lever arm (63) Figure 3.
Before the commencement of a weighing operation the lever (62) is raised by
a handle (74) thereby lifting the plunger (55) by means of the lifting rod (68)
until the catch (60) passes into the notch (61) the slack cord between the
drum (50) and the plunger (55) 'being taken up by the tension pulley (52).
When the dial is revolved by the adjustment of the weighing bob upon the
weighing machine lever the cord is wound upon the drum (50) the shortening
of the cord raising the weight attached to the tension pulley (52).
When the article has been correctly balanced upon the scale the lever (62)
is pulled down by the salesman when the pin (73) upon arm (63) contacts with
the tail piece (72) of the spring catch (60) and the plunger (55) is released.
The weight upon the tension pulley is raised until a stop (75) upon the cord (65)
is retained by a catch (76) and the cord is unwound from the drum (50) as the
dial revolves back to zero, Figure 5.
It is required that until an article has been correctly balanced upon the scale
the dial shall be revolvable in either direction and the weighing bob (1) and
consequently the slide block (3) working with it shall be capable of movement
backwards and forwards, but directly the article has been weighed and the price
push button. operated then the operator shall not be able to move the weighing
bob (1) backwardly until the lever (62) has been brought down to its full extent.
This result is secured by the following arrangement illustrated in Figure 11.
The dial has notches (77) around its periphery one opposite to each column
of cost markings and one or other of them is always engaged by a spring catch (78)
unless said catch is pressed down by the bottom of the plate (20) referred to at
the back of the dial consequently when the cover plate is caused to rise in the
manner before described the dial cannot be revolved until the cover plate is
returned. See also Figure 3.
Referring now particularly to Figures 16 and 17.

page_text: The sprocket wheel (7) in front of the dial has ratchet teeth (79) upon its
inner face engaged by a pawl (80) upon a pivoted arm (81) and 'kept in engage-
ment with the ratchet teeth by a spring (82) around a spindle (83) projecting
rearwardly from the arm (S1) and provided with a pin (84) engaged by one end
of a lever (85) pivoted at (86) upon the casing of the apparatus and having its
other end projecting into the path of the lever arm (63) by which it is operated
to disengage the pawl from the ratchet teeth when the lever is pulled down.
(See also Figs. 1 to 4.)
A push button (87) projecting in front of the pawl arm (81) enables the pawl
to be pushed out of engagement with the ratchet teeth when it is desired to
move the weighing bob back upon the lever of the weighing machine: but as
before described when one of the price push buttons has been operated then the
dial is locked by one of the notches (77) and spring catch (78) Figure 11 so that
if the pawl push button (87) be operated the dial cannot be revolved back until
the lever (62) has been pulled down.
To return the cover plate (17) to its zero or normal position the lever (62)
engages with a pin (88) projecting from a second plate (89), (clearly shown in
Figures 6 and 7) sliding over the cover plate (17) and having a vertical slot to
enable the dial markings to be seen.
The plate (89) has a bridge (90) connecting it to a plate (91) which slides
over the plate (20) at the back of the dial, a spring (92) upon a spindle (93)
fixed to the bridge (19) and passing through bridge (90) tends to keep the
bridges apart but when said spring is compressed by the action of the lever (62)
on the pin (88) one bridge is brought down towards the other and all the plates
slide together until the bracket (29) at the foot of the cover plate (17) passes
under the hook (28) upon the sliding bar (30) referred to and is thereby held
down. See Figure 12.
It is also required that when the lever (62) has been pulled down it cannot
be returned until the dial which has been set in motion thereby has returned to
its zero position. This arrangement is shown in Figures 14 and 15.
A hook (91) pivoted at (99) upon the casing of the apparatus normally pro-
jects into the path of the lever arm (63) under influence of a spring (92") and
when the lever (62) is pulled down said hook is pushed aside until the lever arm
has passed when it passes over it and prevents its return.
In this position an extension (93) from the hook is in the path of a bracket (94)
fixed upon the dial and when the dial is returning to zero said extension is
struck and the hook moved back out of engagement with the lever.
To prevent the dial from revolving back to starting point with too much
impetus a brake is employed shown in Figure 21. Said brake consists of a
lever (95) pivoted at one end (96) upon the casing of the apparatus and having
a projection (97) engaged by the arm. (63) when the main lever is pulled down,
the lever being thereby pressed down upon the periphery of the dial, a spring (98)
draws the brake out of contact with the dial when the main lever is raised.
We will now describe the registering arrangement which is shown more par-
ticularly in Figures 6 to 8.
A lever bracket (a) is pivoted in a bearing (b) attached to the sliding plate (20).
A reel of ribbon paper (c) is carried on a stud (c) projecting from lever (a)
the paper being led around a rubber pressure roller (2) journalled on the lever
and from thence passed between a roller (e) fixed upon a spindle (c) journalled
in the lever and a roller () at the end of a spring (66) secured to a projection (7)
from said lever.
Roller (3) is caused to revolve by a ratchet wheel (c) 'upon its spindle engaged
by a spring pawl (c) which is fixed at 'one end to plate (20) a detent or retaining
pawl (e) being fixed to lever (a), the ratchet wheel is revolved by pawl (c) when
lever (a) is vibrated.
A carbon or ink ribbon (d) similar to those employed upon typewriters is
carried upon a reel (¹) upon a spindle (1) fixed to lever (a) the ribbon being led

page_text: round a curved hinged bracket (d³) beneath a roller (d*) journalled upon the
pivot pin (d) of said bracket and from thence carried to a reel (d) journalled
upon a spindle (7) fixed to lever (a).
The reel (dis partially revolved at intervals by an escapement wheel (9)
to which it is connected and which is engaged by a projection (d) upon a
disc (5) carried upon the same spindle as ratchet wheel (8).
The object of the hinged bracket (3) is to keep the ink ribbon out of contact
with the paper ribbon except when contact is required for printing purposes.
It is shown clearly in Figures 6 and 8 and has lan extending arm (10) which
engages with a pin (1) upon the lever (a) and a spring (2) which engages with
a pin (a) upon the same bracket and limits its upward movement.
An aperture () is provided to permit the paper ribbon to be pushed through
into contact with the ink ribbon (7) and simultaneously the ink ribbon into
engagement with the cost recording type upon the dial when lever (a) is operated
in the following manner.
The upper end of lever (a) is formed with a cam race (a¹) kept in contact
with a cam roller (2) carried upon a bracket (a) fixed to the slide plate (91) by
a spring (a) between said plate and the lever.
When the main operating lever (62) is operated the bridge (90) in moving
down towards the bridge (19) takes with it the plate (91) to which is attached
the cam roller (a2).
When said cam roller is moved down a short distance the shape of the cam
race (a) allows the end of the lever to spring out under pressure of the spring (a)
and the opposite end of the lever carries the pressure roller with the paper ribbon
around it into contact with the ink ribbon through the aperture in the hinged
bracket and the ink ribbon into contact with the registering type so that the
paper receives a printed record of the cost of the article upon the scale.
The curved hinged bracket (d³) is pushed back by contact with the dial.
A further downward movement of plate (91) causes the cam roller (a²) to force
the upper end of the lever inwards and the paper and ink ribbons are withdrawn
from the type the spring catch (2) upon the arm (10) causing the hinged
bracket (3) to keep the ink ribbon away from the paper ribbon.
The outward movement of the upper end of the lever bracket (a) also causes
the spring pawl (c) to revolve the ratchet wheel through one tooth and causes
paper ribbon to be drawn off the reel (c) and delivered outwardly between the
rollers (3) and (c).
We will now describe an arrangement by means of which the total weight is
indicated of a number of articles weighed upon the weighing machine referring
now more particularly to Figures 9 and 10 of the drawings.
A bracket (e) extending upwardly from the bearing (el) carrying the dial
axle (13) has a lever arm (e) pivoted upon it which carries at its opposite end
a counter (e) of ordinary construction.
Lever arm (e) has a tube (e) fixed upon it in which works a plunger (e) a
part of which extending above the cylinder has a spring (e) coiled around it
bearing between the end of the cylinder and a head (e) upon the end of the
plunger.
When the lever arm (63) is operated as herein before described its end engages
with the head (e) and forces the lever arm (e) down until a pinion (e) attached
to and driving the counter, comes into gear with a spur wheel (e) fixed upon
the dial axle.
A bracket (e) to which is attached a spring (e) assists to prevent the pinion
being forced too deeply into gear with the spur wheel, downward motion of lever
arm (63) beyond that necessary for the purpose, being taken up by the plunger (es)
passing into tube (e).
By the above arrangement the counter is only in gear when a weighing has
been performed and the dial is returning to zero.

page_text: Any one of a large number of existing counters can be used for our purpose,
one with which we are acquainted is shown diagrammatically in Figure 10.
The short cylinders-fl-f³-f6- having a common axis have numerals 1 to
10 upon their circumferential peripheries.
The right hand or unit cylinder (f") is connected directly to pinion (es) before
referred to and is caused to revolve (by arranging the relative sizes of the spur
wheel (e) and pinion (e), through the space of one numeral for each pound
weighed upon the machine.
At the end of each revolution a projecting pin (2) engages in a tooth of the
ratchet wheel (f³) made integral with a pinion (f) which gears with internal
teeth cut in the second or tens cylinder (f³) which is thereby moved through
the space of one numeral upon its periphery.
Cylinder (f³) has also a pin (f) which at each revolution actuates a ratchet
wheel (3) giving motion to the third cylinder (f) as described in regard to (f³).
We will now describe the principal operations of apparatus in the order in
which they are performed.
The lever (62) is normally kept in its raised position and the action of balanc-
ing an article upon the scale by means of the weighing bob causes the slide
block (3) to be moved along and the dial to be revolved by the sprocket wheels
(7), (10), (12) and driving bands (5) and (11).
One of the push buttons actuating the cost indicating apparatus is then
operated and the cover plate allowed to rise and to show through an aperture
the cost of the article.
The rising of the cover plate locks the dial by the retaining catch (78) and
the lever is then pulled down thereby pressing down the plate (89) by means of
the pin (88) and actuating the recording mechanism, continued movement of
the lever brings the cover plate (17) back to zero and sets the dial free while the
arm (63) upon the lever (62) releases the weighted plunger (55) and at the
same time throws pawl (80) out of engagement with the sprocket wheel (7) and
the dial returns to zero.
The arms (63) also brings the pinion upon the counter into gear with the
spur wheel and the weight of the article in pounds is thereby totalled upon
the counter.
The lever (62) is then raised and the cycle of operations is complete.
