PROVISIONAL SPECIFICATION.
Improvements in and relating to Weighing Machines.
I, ROBERT WILLIAM PAGE of 82 High Street, Cheltenham, in the County of
Gloucester Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to weighing machines and more particularly to machines or
apparatus of that kind or class intended for receiving payment and delivering records
of weight in exchange therefor.
An important feature in my said invention is the provision of means whereby an
initial or preliminary movement of the weighing platform of the apparatus which
takes place upon the body to be weighed being placed therein, and before the said
platform operates the weighing mechanism, causes the winding up of one or more
weights adapted to operate a device for printing and delivering a ticket with the
weight of the body upon the platform registered or recorded thereon. The automatic
printing and delivery of the said ticket being performed independently of the
weighing mechanism, thus obviating the inaccuracy in weighing caused by the
friction engendered by the printing and delivery device, when the latter is operated
by the said weighing mechanism.
My said invention comprises moreover various other improvements hereinafter set
forth.
In carrying my said invention into practice I provide an upper and a lower
weighing platform. The lower platform is supported upon the weighing levers in
the usual manner. Upon the under side of the upper platform I provide one or
more rods or stems having spiral or other suitable springs, the extremities of which
bear against the underside of the upper platform and against the upper surface of
the lower platform. The upper platform is normally retained by the action of this
spring or springs in a position more or less elevated as may be required above the
said lower platform so as to permit a predetermined amount of initial or preliminary
movement thereof. A link or connecting rod pivoted at one extremity to a lug
provided upon one of the levers or to a lug on the lower platform and at the other
to a lug provided upon the underside of the upper platform forms a guide to govern
the movement of the said platform, I provide moreover lugs or projections upon
the underside of the said upper platform which when the latter has descended a
certain distance, owing to a superimposed weight compressing the above mentioned
spring or springs, bear against the lower platform and permit the said platform and
levers to act in the usual manner. I employ any well known arrangements of lever or
levers coupled by means of a connecting rod steel band or in any other suitable manner
with a shaft or spindle carrying a weighted arm or any other suitable counterpoise.
Upon the said shaft or spindle I provide a clutch one portion of which gears by
means of a tooth or projection with the drum or pulley operating the counterpoise
shaft. This part of the clutch is free to turn in one direction upon the said shaft or
spindle independently of the said drum or pulley but is prevented from movement
in the other by the said tooth or projection engaging with a corresponding tooth or
projection upon the said druin or-pulley. I provide mereover upon this part of the
clutch a groove upon which is wound a cord carrying a small weight which normally
retains the projection upon this half or part of the clutch against the tooth or
projection upon the drum or pulley of the counterpoise shaft, and causes the said

page_text: part of the clutch to follow the movements of the counterpoise. I provide more-
over a device comprising a sleeve carried by a suitable bracket attached to the frame
of the machine. This sleeve carries the other half or part of the clutch, and two
grooved wheels, over which are passed or upon which are wound the extremities of
a cord carrying a weight suspended therefrom by means of a suitable roller.
The part of the clutch upon the sleeve is attached to the extended boss of one of the
said grooved wheels. Upon this boss is also provided a bevel or mitre wheel so arranged
by means of a feather running in a groove in the said boss or otherwise, that the said
grooved wheel is free to move laterally upon the said sleeve to or from the other part
of the clutch without carrying with it the mitre or bevel wheel. The shatt or spindle
of the counterpoise passes through this sleeve without touching or bearing against it.
The other grooved wheel moreover is provided with a roller or rollers adapted to bear
against, an inclined plane or surface, or engage on either side of a portion of a screw
thread provided upon a suitable bracket or otherwise supported. When the said
grooved wheel is rotated in one or the other direction these rollers will cause the latter
to move laterally in one or the other direction upon the said sleeve. In order to
provide for the immediate gearing of the two parts of the said clutch I prefer to attach
upon one part thereof a disc of india-rubber or other suitable material, and to provide
upon the other part points or projections, or knife blades adapted to impinge against
the said disc of rubber or other material when the said parts are brought together.
The bevel or mitre wheel hereinbefore mentioned gears with another bevel or mitro
wheel provided upon the shaft or spindle of a wheel carrying the type, or the printing
wheel, so as to operate the same in the manner hereinafter described. The above
described grooved wheels are retained in position when the cord carrying the weight
is wound thereon by means of a suitable detent or catch which can be released by the
insertion into the apparatus of a coin or coins of the proper size and value.
In order to facilitate the release of the said detent or catch I prefer to provide
another grooved wheel baving a cord carrying a weight passed over or wound thereon.
This wheel is prevented from rotating by the engagement of the spindle of the coin
lever in a slot provided in its periphery. The said spindle is provided with a cutaway
part or portion, which when the coin lever is depressed by a coin or coins of the
proper weight falling upon its projecting extremity and thereby rotating the said
spindle, is brought opposite the slot in the said wheel which is thus released. Upon
the axis of this wheel is provided a cam which when the said wheel is released and is
caused to rotate through the action of its weight actuates a balanced lever, a tooth or
projection upon which engages normally with another tooth or projection upon the
grooved wheel engaging with the inclined plane or screw thread upon the herein before
mentioned sleeve, the said grooved wheel is then disengaged or released, and is
rotated owing to the action of its weight.
The type or printing wheel has upon its side and near its edge type representing
the number of pounds which the apparatus is capable of weighing from zero upwards.
I also provide fixed type representing any other matter that it may be deemed desirable
to print upon the ticket delivered to the person operating the apparatus. I provide
moreover a suitable impression arm or lever adapted to press the ticket or paper
against the said type, feed rollers, to move forward the paper upon which the
record is printed, and a suitable guillotine or knife to cut off a portion of the
said paper and form a ticket after the impression. The above mentioned impression
arm or lever, and guillotine or knife, are actuated successively by means of cams
provided upon the axis of another grooved wheel or pulley over which is passed
or upon which is wound a cord carrying a weight, which wheel is normally
prevented from rotating by means of a suitable detent or catch. The upper feed
roller is carried upon the same axis as the above mentioned grooved wheel or
pulley and is provided with suitable gearing to connect its motion with the lower
feed roller. Suitable portions of the peripheries or surfaces of the said feed
rollers are cut away so as to leave the paper stationary during the operation of
printing and whilst the said paper is being cut off to form the ticket.
The paper upon which the record of the weight is printed, and which forms the

page_text: tickets is preferably in the form of a roll of paper of the requisite width carried
upon a spindle arranged to turn freely in suitable bearings provided upon the
frame of the machine. Any convenient device is employed for inking the type or
printing wheel.
The various grooved wheels actuated by weights for operating the printing device
are provided with other cords passed over or wound upon them.
These cords are connected to other grooved wheels or pullies supported in such a
manner as to rotate freely in suitable bearings in the lower part of the apparatus,
and each adapted to be turned through a portion of a revolution by the initial
movement of the upper platform so as to turn the said operating grooved wheels in
an opposite direction, and wind up the weights carried by their cords.
Upon the upper platform is provided an arm or extension or arms or extensions
having at their extremities pins adapted during the initial or preliminary movement
of the said upper platform to bear against other pins or projections upon the sides of
the said grooved wheels and thus during the descent of the upper platform in its said
initial or preliminary movement cause the grooved wheels to be rotated through a
portion of a revolution, and be then left free. In this manner I provide for winding
up the operating weights of the printing device, by the said initial or preliminary
movement of the upper platform caused by a superimposed weight before the said
platform is in operative connection with the weighing mechanism.
In the front of the apparatus I provide a window or aperture through which is
visible an indicator shewing the oscillating movements of the counterpoise, so that
the person operating the apparatus may be able to see when the said counterpoise
is at rest or practically at rest, and a correct record of the weight may be obtained by
operating the printing device.
To cushion the movement of the counterpoise upon the sudden superimposition of
a weight upon the upper platform, or its return to its normal position when the said
weight is suddenly removed from the said upper platform, I prefer to provide, instead
of the ordinary dash pot usually employed, a novel device consisting of a wheel or
quadrant secured to the shaft or spindle carrying the counterpoise. The rim of this
wheel or quadrant is formed hollow and a suitable quantity of mercury or other
liquid is inserted therein. In this hollow rim I provide a check which only allows
the said mercury to pass slowly round the hollow rim of the said wheel or quadrant.
A suitable relief pipe is also provided, when a quadrant is employed, to permit the
passage of the air from one side of the said quadrant to the other when displaced by
the movement of the mercury.
The operation of the apparatus is as follows:-that is to say--The body to be
weighed being placed upon the upper platform the latter descends through its initial
or preliminary movement owing to the compression of the herein before mentioned
spring or springs, and the weights actuating the printing device are wound up by the
arm or arms and pins upon the said platform actuating the lower grooved wheels or
pulleys in the manner horeinbefore described. The upper platform then bears upon
the lower platform and the weighing mechanism is brought into operation. The
grooved part of the clutch provided with the small weight follows the movement of
the drum or pulley of the counterpoise shaft. When the person operating the
apparatus sees from the movement of the the hereinbefore mentioned indicator that
the counterpoise is at rest, or practically so, he inserts the coin or coins of the
requisite value into the apparatus and thereby releases the catch or detent detaining
the grooved wheel or pulley imparting a lateral motion to the part of the clutch
carried upon the sleeve thus throwing the clutch into gear.
The detent or catch retaining the second grooved wheel is then released by a
projection upon the first grooved wheel and is immediately rotated by means of its
weight carrying with it the clutch backward for the same distance that it has
previously moved forward with the drum or wheel of the counterpoise, shaft or
spindle the said movement being lesser or greater according to the amount of weight
placed upon the upper platform. This movement also imparts motion through the
hereinbefore mentioned bevil or mitre gearing to the type wheel. The dimensions of

page_text: .
the said bevel gearing are so proportioned that the type or printing wheel will be
moved round the proper distance to bring beneath the impression arm or lever the
figure or figures representing the exact number of pounds, corresponding with the
amount of movement of the said drum or wheel of the counterpoise shaft or spindle
and the part of the clutch moving therewith. The grooved wheel or pulley actuating
the printing device, cams is then released by a projection or wiper upon the clutch
or in any suitable manner, and is rotated in like manner by the action of its weight,
and the said cams are also rotated causing the impression arm or lever to descend
and press the paper against the type. The said arm rising under the action of its
cam the feed rollers then operate so as to move the extremity of the paper bearing
the printed record of the weight the requisite distance through a slot in the casing of
the apparatus. The arm or lever carrying the guillotine or knife is then permitted
to descend by the action of its cam, and cuts off the requisite length of paper so as
to form a ticket which drops into a suitable receptacle upon the outside of the
apparatus from which it can be easily removed by hand.
The extremity of the roll of paper is left in position over the type or printing
wheel for the next operation. When the weight is removed from the upper platform
the clutch remains engaged, and the said upper platform rises again under the action
of its spring to its normal position above the lower platform.
When the upper platform is again depressed through its initial movement the
grooved wheel is moved laterally upon the sleeve by the hereinbefore mentioned
screw thread, during the winding operation, and the part of the clutch connected
therewith is consequently disengaged from the part carried upon the counterpoise
shaft or spindle, and the latter part is then free to follow the movement of the drum
or pulley of the counterpoise shaft.
Although I have herein before described a convenient and advantageous method
of carrying my said invention into practice it is obvious that I can somewhat
modify the construction of my apparatus without departing from the nature of my
invention. For instance instead of winding up the operating weights hereinbefore
described by the initial or preliminary movement of the platform, I can employ
a suitable lever which can be operated by hand from the outside of the apparatus,
for that purpose. I can dispense with the hereinbefore mentioned spring or springs
for retaining the upper platform in its elevated position and employ any suitable
arrangement of levers and counterweights. In some instances moreover I make
suitable provision for operating the printing device without inserting a coin or coins
into the apparatus.

COMPLETE SPECIFICATION.
Improvements in and relating to. Weighing Machines.
I, ROBERT WILLIAM. PAGE of 82 High Street, Cheltenham, in the County of
Gloucester, 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 :-
My invention relates to weighing machines and more particularly to machines or
apparatus of that kind or class intended for receiving payment and delivering records
of weight in exchange therefor.
An important feature in my said invention is the provision of means whereby an
initial or preliminary movement of the weighing platform of the apparatus which
takes place upon the body to be weighed being placed thereon, and before the said
platform operates the weighing mechanism causes the winding up of one or more weights
adapted to operate a device for printing and delivering a ticket with the weight of
the body upon the platform registered or recorded thereon. The automatic printing

page_text: and delivery of the said ticket being performel independently of the weighing
mechanism, thus obviating the inaccuracy in weighing caused by the friction engendered
by the printing and delivery device when the latter is operated by the said weighing
mechanism.
My said invention comprises moreover various other improvements hereinafter set
forth.
In the accompanying drawing I have shown how my said invention may be
conveniently and advantageously carried into practice.
Figure 1 is a front elevation partly in section.
Figure 2 is a similar view to Figure 1 with the front portion of the box or case
removed and partly in vertical section.
Figure 3 is a vertical section on the line x, x Figures 1 and 2 some of the parts
being shown in elevation.
Figure 4 is a horizontal section on the line a¹, Figures 1, 2 and 3 and
Figure 5 is a horizontal section on the line, Figures 1, 2 and 3 drawn to an
enlarged scale showing a weighing machine with my improvements applied thereto.
Figure 6 is a vertical section on the line, Figure 5 and
Figure 7 is a vertical central section on the line at, a Figure 4 drawn to a still
further enlarged scale.
Figure 8 is a portion of Figure 5 drawn to the same scale as Figures 6 and 7
showing details of construction hereinafter described.
Like letters indicate corresponding parts throughout the drawing.
A is the box or case of the apparatus, B is the coin slit or aperture for inserting
coin or their equivalents into the apparatus, C is the aperture through which the
ticket having recorded thereon the weight of the object upon the platform is delivered
to the person operating the apparatus, D is the platform upon which the object to be
weighed is placed. E E are the weighing levers.
The weighing platform D is supported upon a second or lower platform a Figure 3
(which is supported upon the weighing levers E in the usual manner) by means of rods
or stems 6 and spiral or other suitable springs c the extremities of which bear against
the underside of the upper platform and against the upper surface of the lower
platform. The upper platform D is normally retained by the action of the springs c
in a position more or less elevated above the second or lower platform a so as to
permit a predetermined amount of initial or preliminary movement thereof previous
to the weighing operation. d is an H shaped link or connected rod coupled to lugs e
provided upon the lower platform a and to lugs el provided upon the underside of the
upper or weighing platform D thus forming guides to govern the movement of the
said upper platform. f,fare lugs or projections formed upon or firmly secured to
the underside of the upper platform D which when the latter has descended a certain
distance owing to a superimposed weight compressing the above mentioned springs c
bear against the upper surface of the lower platform a so that the said platforms act
upon the levers for weighing in the usual manner. The weighing levers E may be
of any well known kind. The extremity of the long lever is coupled by means of a
connecting rod 9 and a flexible band g¹ formed of steel or other suitable elastic
material with a drum or grooved pulley ¹ firmly secured upon a shaft or spindle h
supported in bearings hereinafter described in a frame i secured to the interior of the
box or case a.
Upon the shaft or spindle I provide moreover a counterpoise preferably consisting
of a curved or bent guide piecej (Figures 2, 3, 4 and 7) and a steel or other band
one extremity of which is firmly attached to the said shaft or spindle h, and to the
other extremity of which is secured a weight, a suitably weighted arm or any other
suitable counterpoise may however be employed in lieu of this arrangement. k kare
the two halves of a clutch (more clearly shown in Figure 7) the half or portion k
of which gears by means of a tooth or projection with a tooth projection or
shoulder upon the drum or grooved pulley h' in such a manner as to be free to
turn in one direction upon the shaft or spindle h independently of the said drum
or pulley but is prevented from movement in the other by the said tooth or

page_text: projection engaging with the said tooth projection or shoulder h³ upon the drum
or grooved pulley h¹. ³ is a groove in which is wound a cord or chain ** carrying
a small weight which normally retains the tooth or projection k³ upon the half
or part of the clutch against the tooth projection or shoulder 7' upon the drum
or grooved pulley and causes the said part or half k of the clutch to follow the
movements of the said counterpoise shaft or spindle when moved or rotated as
hereinafter described. For obviating as far as possible the movements of the
counterpoise shaft or spindle ½ being interfered with by the said shaft or spindle
carrying any parts of the recording mechanism I provide a sleeve / secured by means
of a nut or otherwise to a suitable bracket attached to the frame i of the
machine. The sleeve carries the other half or part k' of the clutch, and two
grooved wheels or pulleys m m' over which are passed or upon which are wound
and firmly secured the extremities of a cord n carrying a weight n¹ suspended
therefrom by means of a suitable grooved wheel or pulley n².
o is a bevel or mitre wheel provided upon the sleeve / between the part or half k¹ of
the clutch and the grooved wheel or pulley m. The part or half k¹ of the clutch is
attached to the said grooved wheel or pulley m by means of studs or distance pieces o¹
passing through suitable holes provided in the bevel or mitre wheel o.
The studs or
distance pieces o' are screwed into the grooved wheel or pulley m and are secured by
means of screws o³ or in any other suitable manner to the part or half k¹ of the clutch.
By this means the said grooved wheel or pulley m and the part or half k' of the
clutch are connected so that they can be moved to and fro upon the sleeve / to throw
the said part or half k¹ of the clutch in or out of gear with the part or half k thereof
without imparting any lateral movement to the said bevel or mitre wheel o.
The grooved wheels or pulleys m m² are connected together so as not to be able to
move away from each other laterally, but to be free to rotate independently of each
other upon the sleeve by means of a collar m² upon the grooved wheel or pulley m¹
which collar is arranged to work in a recess m³ provided in the grooved wheel or
pulley m
and is retained therein by means of a plate m' secured upon the said pulley by
means of screws or in any other convenient manner. The counterpoise shaft or spindle h
passes through the sleeve without touching or bearing against it in any way and the
said sleeve is cut away as shown in Figure 7 for lightness. The counterpoise shaft or
spindle h is supported in quadrants or pieces p hung upon knife edges pl secured to
the frame i. p³ p' are forked pieces also secured to the frame i preventing any
side movement of the said shaft h, and p p are set screws preventing any lateral
movement thereof. I thus provide for supporting the shaft h so as to permit it to
rotate freely with a minimum amount of friction. 9 is a set screw screwed into a
correspondingly screw threaded hole in the boss of the bevel or mitre wheel o and the
extremity of which extends into a circumferential groove provided in the sleeve
and thus prevents any lateral movement of the said mitre or bevel wheel upon the
sleeve whilst permitting it to rotate freely thereon.
are screw threads provided upon the sleeve and adapted to engage in corre
sponding female threads in the boss of the grooved wheel or pulley m².
When the said grooved wheel or pulley m¹ is rotated in one or the other direction
the screw threads will cause the latter to move laterally in one or the other direction
upon the sleeve l. In order to provide for the immediate gearing without slip of the
two halves or parts kk' of the said clutch, I attach upon the half or part k thereof or
in a suitable recess provided therein a disc k of India-rubber or other suitable material
and provide upon the other half or part k points, projections or knife blades k
adapted to impinge against the said disc of rubber or other material when the said
parts are brought together. In Figures 3 and 4 the parts k k¹ of the clutch are
shown in engagement and in Figure 7 out of engagement. The bevel or mitre
wheel o gears with another bevel or mitre wheel (Figures 2 and 3) provided at
or near one extremity of a shaft or spindle at or near the other extremity of which
is attached a wheels (Figures 3, 5 6 and 8) having thereon a suitable scale and type
and which is operated in the manner hereinafter described. The shaft or spindle
is supported in suitable bearings in brackets attached to the frame i. The grooved

page_text: wheel or pulley m¹ is retained in position when the cord n carrying the weight n¹ is
wound thereon by means of a suitable catch or detent levert which is pivoted at t¹
(Figure 2) to the frame i. The said catch or detent lever t is provided with a
tooth which engages with another tooth or projection m³ upon the grooved wheel
or pulley m. tis a counterbalance for balancing the said lever t. The said grooved
wheel or pulley m¹ can be released by the insertion into the apparatus of a coin or
coins of the proper size and value as hereinafter mentioned.
In order to facilitate the release of the said catch or detent lever t I provide a
second or bell crank lever pivoted at t to an extension upon the frame i. The
long arm of the said bell crank lever * is provided with a receptacle or bucket &
for the coins which projects under the lower extremity of a chute B leading from the
coin slit or aperture B. In the outer portion of the bucket or receptacle to is
provided an aperture 7 for permitting the coin to drop therefrom when it has moved
through a sufficient angle to release the detent lever t, and the bottom of the said
bucket or receptacle is formed sloping inwards so as to retain the coin in the latter
until it has moved through the said angle. The short arm of the said bell crank
lever is coupled by means of a connecting rod t with one extremity of the detent
lever t. u is a pawl or catch pivoted at u' to the frame i and which engages with a
tooth projection or shoulder o upon the boss of the mitre or bevel wheel o and
retains the latter and the grooved wheel m in position when the said cord n is wound
thereon. The pawl or catch u is provided with an extension u³ against which is
adapted to bear the projection or tooth m upon the grooved wheel or pulley m¹ so as
to release the said bevel or mitre wheel at the proper moment that is to say when the
grooved wheel or pulley m¹ has performed half a revolution. u³ is another pawl or
catch pivoted at u to the frame and which engages with ratchet teeth m upon the
rim of the said grooved wheel or pulley m for the purpose hereinafter described. m² is
a projection or wiper provided upon the grooved wheel or pulley m¹ for disengaging
the said pawl or catch at the proper moment.
The type or printing wheels has upon its side and near its edge a scale and type s¹
(Figure 8) representing the number pounds which the apparatus is capable of
weighing from zero upwards. 2 is fixed type secured to the frame i representing any
desirable instructions or other matter that it may be deemed necessary to print upon
the ticket intended to be delivered to the person operating the apparatus, and an arrow
or other index which will point to the correct weight of the object upon the weighing
platform upon the ticket, a portion of the scale and figures upon the said type wheel
above and below the said weight being printed thereon. is the paper intended to be
cut off in the manner hereinafter described to form the said ticket (Figures 2, 3, 5,
and 6) is an impression arm or lever one extremity of which is pivoted at to a
bracket secured to the frame i and the other extremity of which is provided with
a plate or platen ³ adapted to press the ticket or paper against the said type. 4 is a

rollers 10, we. The impression armor lever and guillotine or knife blade-
actuated successively by means of cams y of similar shape and dimensions provided
upon the shaft or spindle y* of another grooved wheel or pulley y' over which is
passed or upon which is wound a cord y carrying a weight y. The shaft or spindle y*
is supported in suitable bearings in the brackets and in a bracket 10 secured to the
frame i. The grooved wheel or pulley y is normally prevented from rotating by
means of a suitable catch or pin y provided upon a detent lever y pivoted at y to
the frame and which engages in a recess or groove y' provided in a disc y³ secured
upon the shaft or spindle y*. The detent lever y is coupled by means of a connecting
rod y with the long arm or one arm of a bell crank lever 10 pivoted at y" to the
frame the other or short arm of the said bell crank or other lever extends into the
path of a projection or wiper m* upon the part or half k of the clutch. The said
short arm or other arm of the lever y10 is provided with a suitable joint which permits
the projection or wiper m* to pass without lifting or moving the said lever on its
return to its normal position, or other suitable means are provided for this purpose.
The upper feed roller w is carried upon the said shaft or spindle y* and suitable
gearing y is provided to connect its motion with the lower feed roller w¹ in some
instances the gearing y" is dispensed with. Suitable portions of the periphery or feed
surface of the upper feed roller wo is cut away as shewn in Figures 2 and 6 so as to
leave the paper stationary during the operation of printing and whilst the said paper
is being cut off to form the ticket by the knife blade as hereinafter described.

The paper upon which the record of the weight is printed, and which is intended
to form the tickets is preferably in the shape of a roll of paper of the requisite
width carried upon a spindle * arranged to rotate freely in suitable bearings pro-
vided upon the brackets. Any well known device not shown in the drawing is
employed for inking the type or printing wheel.
The grooved wheels or pulleys m, m' and y¹ are provided moreover with other
cords wires or chains n³ and y passing over or wound upon them. The cords
wires or chains n³ are connected by means of a grooved pulley n' with a cord wire
or chain n° and the said cords wires or chains 7 and y are connected to grooved
wheels or pulleys 2, 2* firmly secured to shafts or spindles 21, 22 supported in
suitable bearings in brackets 23, (attached to the box or case A) in such a manner as
to rotate freely therein. The said grooved wheels or pulleys 2, * are each adapted
to be turned through a portion of a revolution by the initial movement of the upper
platform D so as to turn the said operating grooved wheels m m' and y¹ in an
opposite direction and wind up the weights n' y carried by the cords ny. For this
-purpose I provide upon the upper platform D an arm or extension D' either formed
in one therewith or firmly attached thereto and having at its free extremities pins D*
adapted during the initial or preliminary movement of the said upper platform D to
bear against a pin or projection upon the side of the grooved wheels or pulley z
and against a pin or projection upon the side of a disc z secured to the shaft
or spindle and thus during the descent of the said upper platform I) in its said
initial or preliminary movement cause the grooved wheels or pulleys 2 z* to be
rotated through a portion of a revolution and be then left free and thus through
the cords wires or chains n³ n³ and y³ also to rotate the grooved wheels or pulleys m m'
and y' and wind the cords wires or chains n, y³, carrying the weights n³ y³ thereon.
In this manner I provide very simple means for winding up the operating weights
for throwing the parts or halves k¹ of the clutch in gear and for actuating the
printing device by the said initial or preliminary movement of the upper platform D
caused by a superimposed weight, and before the said platform is in operative
connection with the weighing mechanism.
To cushion the movement of the counterpoise shaft or spindle h and counterpoise
upon the sudden superimposition of a weight upon the upper platform D and the con-
sequent descent thereof upon the second or lower platform a, or upon its return to its
normal position when the said weight is suddenly removed from the said upper
platform, I provide instead of the ordinary dash pot usually employed a novel device

page_text: consisting of a wheel or quadrant F (Figures 1, 3 and 4) secured to the shaft or
spindle carrying the said counterpoise the rim of the wheel or quadrant F is formed
hollow and a suitable quantity of mercury or other liquid F¹ is inserted therein. Fis
a check which only allows the said mercury to pass slowly round the said hollow
rim of the said wheel or quadrant. F is a suitable relief pipe connecting the
extremities of the said quadrant to permit the passage of the air from one side of the
latter to the other when displaced by the movement of the mercury or other liquid
in the said hollow rim thereof. Instead of the said wheel or quadrant I may employ
any well known arrangement of dash pots for a like purpose. Suitable dash pots may
also be employed for cushioning the movement of the weights n¹ y³.
A¹ (Figures 1 and 3) is a window or aperture provided in the front of the box
or case A of the apparatus through which is visible an indicator A showing the
oscillating movements of the counterpoise, so that the person operating the apparatus
may be able to see when the said counterpoise is at rest or practically at rest and a
correct record of the weight may be obtained by inserting the requisite coin into
the apparatus to release the mechanism for operating the printing device.
The operation of the apparatus is as follows:-that is to say, the body to be
weighed being placed upon the upper platform D the latter descends through its initial
or preliminary movement owing to the compression of the hereinbefore mentioned
springs c and rests upon the second or lower platform a through the lugs or pro-
jections. The weights n' y, actuating the clutch and the printing device are wound
up by the arm or extension D' and pins D³ rotating the lower grooved wheels or
pulleys through a portion of a revolution and through the cords wires or chains n³n³
and y also imparting rotating motion to the grooved wheels or pulleys mm² and y¹
and winding thereon the cords wires or chains n y* carrying the weights n¹ y³ as
herein before described.
During this operation the grooved wheel or pulley m³, and consequently the grooved
wheel or pulley m and the half or part k¹ of the clutch are also moved backward so as
to disengage the latter from the half or part k thereof, by means of the screw thread 1³
upon the sleeve l. The grooved wheel or pulley m, the part or half of the clutch
and the bevel or mitre wheel o being prevented from rotating by the pawl us until the
said grooved wheel or pulley m' has performed its half revolution and thus completely
disengaged the part or half k¹ of the clutch from the part or half k thereof, when the
said pawl is disengaged by a projection m' upon the said grooved wheel or pulley m¹
and the wheel or pulley m is rotated by the grooved wheel or pulley z so as to also
wind the cord wire or chain n thereon. The liability of the clutch being injured by a
premature rotary movement is thus obviated.
The upper or weighing platform D will then descend so as to permit it to rest
through the lugs or projections upon the second or lower platform a and the
weighing levers E will be operated or moved by the weight upon the said platform D
to rotate the counterpoise shaft or spindle through the connecting rod g flexible
steel or other band g¹ and drum or grooved pulley h. The half or part k of the
clutch follows the movement of the said counterpoise shaft or spindle under the action
of the weight ** as hereinbefore described. The person operating the apparatus by
noting whether the indicator A' is in motion or otherwise through the window or
aperture A' is enabled to judge of the right moment when the counterpoise is at rest
or practically so, a coin or coins of the requisite value should then be inserted into the
slot or slit B. The said coin will fall down the chute B' and drop into the bucket or
receptacle and depress the extremity of the lever t and consequently release the
detent lever t. The grooved wheel or pulley m' is then permitted to rotate under
the action of the cord wire or chain n and weight and is moved forward upon the
sleeve by means of the screw threads 1, the grooved wheel or pulley m and the
part or half of the clutch being also moved until the projections or knife blades k'
upon the said part or half k' are engaged with the rubber or other disc ko in the part
or half k. The catch or pawlu retaining the bevel or mitre wheel o is then disengaged
by the projection or wiper m' upon the grooved wheel or pulley m¹ and the wheel or
pulley m is permitted to rotate under the action of the cord wire or chain n and

weight n so as to move the clutch backward for the same distance that it has previously
been moved forward or followed the drum or pulley h¹ of the counterpoise shaft or
spindle h the said movement being lesser or greater according to the amount of weight
placed upon the upper platform D. This movement also imparts motion through the
herein before mentioned bevel or mitre wheels o, r'to the shaft or spindle and the
type wheel s. The dimensions of the said bevel gearing o, rare so proportioned that
the type or printing wheel s will be moved round the proper distance to bring beneath
the plate or platen of the impression arm or lever v and opposite the herein before
mentioned arrow the figure or figures or division upon the scale representing the
exact number of pounds corresponding with the amount of movement of the said drum
or wheel of the counterpoise shaft or spindle h and the part or half k of the clutch
moving therewith as shown in Figure 8. The grooved wheel or pulley y actuating
the printing device cams y is then released by the projection or wiper m⭑
upon the
part of the clutch m disengaging the detent lever y through the lever 10 and
connecting rod y' and the said grooved wheel or pulley is rotated in like manner by
the action of its weight y, the cams y upon the shaft or spindle y* of the said
pulley y' are also rotated thus permitting the impression arm or lever v¹ to descend
and the plate or platen v³ on the extremity thereof to press the papor v against the
type s upon the wheels and against the fixed types. During this time the cut-away
portion of the upper feed roller c is opposite the paper v and consequently there is
no feed or movement thereof. The said arm v' then rises under the action of its
cam and the feed rollers to w¹ operate so as to move the extremity of the paper
bearing the printed record of the weight the requisite distance through the slots
and C. The arm or lever a carrying the guillotine or knife blade is then permitted
to descend by its cam y so as to cut off the requisite length of the paper to form a
ticket. This ticket drops into a suitable receptacle or tray Cupon the outside of
the apparatus, from which it can be easily removed by hand. A portion of the scale
of movable type equal to the width of the ticket is printed at each operation, its
relative position to the arrow or index printed by the fixed type varying according
to the movement of the type wheel o under the action of the object upon the weighing
platform.
The extremity of the roll of paper is left in position over the type or printing
wheels for the next operation. When the weight is removed from the upper plat-
form D the portions of the clutch remain engaged, and the said upper platform
rises again under the action of the springs c to its normal position above the lower
platforin a. When the upper platform D is again depressed through its initial move-
ment as shown in dotted lines Figure 3. the grooved wheel or pulley m² is moved
laterally upon the sleeve by the hereinbefore mentioned screw thread 13 during the
winding operation, the part of the clutch being held by the hereinbefore described
pawl and ratchet teeth m³ until the said disengaging movement is completed as
hereinbefore mentioned, when the said pawl u³ is lifted or thrown out of engagement
by the projection or tooth m. When the grooved wheel or pulley m and bevel or
mitre wheel o revolve under the action of the weight n', the said pawl u³ slides over
the ratchet teeth me withont engaging therewith.
Although I have hereinbefore described a convenient and advantageous method of
carrying my said invention into practice it is obvious that I can somewhat modify the
construction of my apparatus without departing from the nature of my invention.
For instance instead of winding up the operating weights hereinbefore described by
the initial or preliminary movement of the platform, I can employ a suitable lever
which can be operated by hand from the outside of the apparatus for that purpose.
I can dispense with the hereinbefore mentioned spring or springs for retaining the
upper platform in its elevated position and employ any suitable arrangement of levers
and counterweights. In some instances moreover I make suitable provision for
operating the printing device from the exterior of the apparatus, without inserting a
coin or coins into the apparatus, hy any convenient arrangement of levers. Moreover
the clutch for operating the type-adjusting, the printing, and delivery mechanism may
be arranged to be operated by hand if desired.
