I, WILLIAM THOMAS WHITEMAN, of No. 7, Staple Inn, in the County of Middlesex,
Patent Agent, do hereby declare the nature of this invention for "IMPROVEMENTS IN
WEIGHING AND WEIGHT PRINTING MACHINERY AND IN MECHANISM FOR CONTROLLING
WEIGHT PRINTING AND OTHER MACHINERY OR APPARATUS, BY MEANS OF COINS
OR TOKENS," to be as follows:
This invention relates more particularly to machines for weighing persons and
delivering to them tickets printed with their respective weights, on the introduction
of proper coins or tokens into the machine; but it may in part at least, be otherwise
applied.
First. The invention comprises new or improved means for weighing or balancing
the weight of the persons or objects. For this purpose a system of crossed and jointed
levers like lazy tongs, is employed to convey the pressure, due to the weight of the
person or object, to the scale weights or other balancing appliance or appliances. The
joints of the system of levers are formed by means of knife edges so as to work with
as little friction as may be. A balancing appliance or appliances of any suitable
description may be employed, but it is especially intended to employ a series or chain
of balance or scale weights which are successively lifted until a sufficient number are
suspended to balance the weight of the person or object on the scale. In connection
with such a series of scale weights the aforesaid crossed and jointed levers are
particularly useful as they will give as large a motion as may be desired in a straight
line.
Second. The invention comprises new or improved means for preventing sudden
motion of the scale. For this purpose one or more clutches provided each with a fan
or winged arm, or an equivalent operating contrivance, are mounted on a suitable part
of the scale which has a comparatively large motion, and are arranged to clutch or

page_text: engage another part which has a less motion, or moves in the opposite direction, or is
stationary, so that, for example, when a person steps on or off of the scale, the first
quick motion brings the clutch or clutches into action in consequence of the resistance
to the motion of the fan or fans so that said clutch or clutches check the motion, but
when equilibrium is approached the slow motion or the cessation of movement permits
the fan or fans to resume the normal position and releases the clutch or clutches
leaving the scale free to balance without friction.
Third. The invention comprises new or improved means for adjusting printing type
for recording the results of the weighings. For this purpose the printing type are
mounted on a carrier bar, which is suspended from and moved by the aforesaid system
of crossed and jointed levers. The printing type are supported on the carrier bar by
separate springs or other suitable means, so that they can be pushed out independently
of the said carrier bar and practically of one another; and teeth are provided on the
back of the type or elsewhere, so as to be engaged by an appropriate finger, in order
that the type and carrier may be held in position in printing. It will be understood
that a pointer or some other contrivance could be used to indicate the results of the
weighings to the eye instead of or in addition to the means for recording the said
results.
Fourth. The invention comprises new or improved means for printing the weights,
or results of the successive weighings, upon tickets and for delivering the said
tickets as they are printed. For this purpose in a suitable case below a card box
containing a pile of the tickets there is arranged a feed roller with many sides, which
is so constructed that it withdraws the cards or tickets one at a time from the box and
presents them successively to the printing type, in order that they may receive an
impression from the particular type which the motion of the weighing scale may bring
into position for printing.
The feed roller as well as the printing finger, or means for giving an impression, it
is specially designed to operate by means of a coin controlled clock-work or power
driven mechanism; although the invention is not restricted to that mode of operating
them.
The invention further comprises certain particular constructions and combinations of
the elements hereinbefore or hereinafter mentioned.
In carrying the invention into effect, the crossed and jointed levers are arranged
vertically, the top pair having knife edges which are supported by stationary bearings
and the other levers being suspended from the lower ends of said pair; the scale beam
of an ordinary platform scale is connected by a vertical tension rod with the levers
above the said stationary bearings, so that when the scale beam is depressed the top
pair of levers are turned and the other levers are both turned and lifted after the
manner of the outer levers of lazy tongs; and the series or chain of scale weights
are connected with a hanger suspended by links from the lower ends of levers at the
bottom of the system so that they are lifted vertically. The crossed and jointed levers
are made double to give lateral stiffness and the ends of the knife edges at the joints
are covered by plates which prevent end wise motion, said ends being pointed in order
to reduce the friction to a minimum.
Two automatic clutches are carried by the said hanger and are adapted to engage
the aforesaid tension rod which passes through the hanger. Each clutch consists of a
sleeve pivoted on a horizontal axis and provided with a fan which projects at right
angles from one side and is counterbalanced so that normally the fan is horizontal and
the clutch sleeve vertical. The sleeves surround the tension rod. The two fans
project in opposite directions.
The type carrier in the form of a straight bar is fastened in a vertical position to
the front of the aforesaid hanger. The type (of metal) are cast separately and are
each supported by a bowed metal spring whose opposite end is clamped against the
type carrier. On the back of each type is a tooth. A printing finger, arranged in
the space between the type and the carrier, is moved in the direction to push out a
type and give an impression, by means of a clock work, which is driven by a weight
and is temporarily released by the action of a proper coin or token on a detent or

page_text: escapement lever. The card or ticket to be printed is held by means of the feed
roller and its case in a vertical position in front of the printing finger on the opposite
side of the type therefrom. The back of the case is slotted for the passage of the
type and an interposed ink or carbon ribbon. The feed roller is operated to discharge
the printed card or ticket and to supply a blank card or ticket in its place by means
of the aforesaid clock work.
The supplemental coin holder which receives the coin after it has released the clockwork
is arranged behind a pane of transparent glass so as to hold it in view. It is connected
with the clockwork so as to discharge the coin when the said clockwork is next
released. In one form it is composed of a finger, which extends across a coin shoot or
passage and arrests the descent of the coin when the latter has passed the detent or
escapement for the clockwork, and which is temporarily withdrawn to discharge the
coin, when the clock work is next released and allowed to revolve, the coin which effects
the release being retained on the detent or escapement levor until the holding finger
has been returned into position to receive it. In another form, it is composed of a
shelf which receives the coins and from which they are removed by one of a series of
radial arms which sweep over the shelf and are moved by the clockwork. It could be
made in a great variety of forms, and adapted to the special machinery which it is
desired to control by means of coins.

page_text: I, WILLIAM THOMAS WHITEMAN, of No. 7, Staple Inn, in the County of Middlesex,
Patent Agent, do hereby declare the nature of this invention for 1MPROVEMENTS IN
WEIGHING AND WEIGHT PRINTING MACHINERY, (a communication to me from abroad
by the United States Machine and Inventions Company of New York, in the
United States of America, Manufacturers), 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 more particularly to machines for weighing persons and
delivering to them tickets printed with their respective weights, on the introduction
of proper coins or tokens into the machine; but it has reference also to weighing and
weight printing machinery whether controlled by coins or not.
First. The invention comprises new or improved means for weighing or balancing
the weight of the persons or objects. For this purpose a system of crossed and jointed
levers like lazy tongs, is employed to convey the pressure, due to the weight of the
person or object, from the platform or other support for such person or object, to the
counterpoise composed of scale weights or other balancing appliance or appliances.
The joints of the system of levers are formed by means of knife edges so as to work
with as little friction as may be. A balancing appliance or appliances of any suitable
description may be employed, but it is especially intended to employ a series or chain
of balance or scale weights which are successively lifted until a sufficient number are
suspended to balance the weight of the person or object on the scale. In connection
with such a series of scale weights the aforesaid crossed and jointed lovers are
particularly useful as they will give as large a motion as may be desired in a straight
line.
Second. The invention comprises new or improved means for preventing sudden
motion of those weighing scales which have a counterpoise composed of a chain of
connected weights or other appliance or appliances whose balancing effect increases
automatically and progressively with the motion of the scale. For this purpose one
or more clutches provided each with a fan or winged arm, or an equivalent operating
contrivance, are mounted on a suitable part of the scale which has a comparatively
large motion, and are arranged to clutch or engage another part which has a less
motion, or moves in the opposite direction, or is stationary, so that, for example, when
a person steps on or off of the scale, the first quick motion brings the clutch or clutches
into action in consequence of the resistance to the motion of the fan or fans so that
said clutch or clutches check the motion, but when equilibrium is approached the
slow motion or the cessation of movement permits the fan or fans to resume the
normal position and releases the clutch or clutches leaving the scale free to balance
without friction.
Third. The invention comprises new or improved means for adjusting the printing
type for recording the results of the weighings. For this purpose the printing type
are mounted on a carrier bar, which is suspended from and moved by the aforesaid

page_text: system of crossed and jointed levers. The printing type are supported on the carrier
bar by separate springs or other suitable means, so that they can be pushed out
independently of the said carrier bar and practically of one another; and teeth are
provided on the back of the type or elsewhere, so as to be engaged by an appropriate
finger, in order that the type and carrier may be held in position in printing. The
use of teeth attached to type on a yielding support so that the teeth and type would
be pushed out together, constitutes a special feature of invention. It will be under-
stood that a pointer or some other contrivance could be used to indicate the results
of the weighings to the eye instead of or in addition to the means for recording the
the said results..
Fourth. The invention comprises a new or improved combination with or
arrangement in weighing scales having a counterpoise composed of a chain of
connected weights or other appliance or appliances, whose balancing effect increases
automatically and progressively with the motion of the scale, of the weight printing
type, the printing finger or other device for giving the impression and the means for
supplying tickets and presenting them in position for printing and for delivering the
printed tickets; that is to say the combination or arrangement of these parts is such
that the movements of the weighing scale under the pressure of the object weighed
adjust the printing typo (which are or may be such as before indicated) in front of a
printing finger, or other device, which moves horizontally to give the impression
while the tickets are taken from an upright card box, wherein they are placed
horizontally, are turned into a vertical position in front of the said horizontally
movable printing finger or other device to receive the impression from the type
under the pressure of said finger or other device and are discharged at once when
printed.
Fifth. The invention comprises now or improved means for printing the weights,
or results of the successive weighings, upon tickets and for delivering the said tickets
as they are printed. For this purpose in a suitable case below a card box containing
a pile of the tickets there is arranged a feed roller with many sides, which is so
constructed that it withdraws the cards or tickets one at a time from the box and
presents them successively to the printing type, in order that they may receive an
impression from the particular type which the motion of the weighing scale may bring
into position for printing.
The feed roller as well as the printing finger, or means for giving an impression,
it is specially designed to operate by means of a coin controlled clockwork or power
driven mechanism; although the invention is not restricted to that mode of operating
them.
The invention further comprises the combination with the balancing and the weight
printing and ticket delivering mechanisms before indicated, of a coin controlled clock-
work or power driven mechanism for operating the same; and also the construction,
combination and arrangement of the knife edges in the system of lovers or lazy tongs
for conveying the pressure to the counterpoise, and of the whole machine as illustrated
in the drawings which form part of this specification, and as hereinafter described
with reference thereto.
In the accompanying drawings which form part of this specification,-

Fig. XIII is a plan of the last mentioned holder; and Fig. XIV is a detailed view
in vertical section of the clutch mechanism.
Referring to the machine as represented in Figs. I-X the lever A of an ordinary
platform scale is connected with the lower end of the scale rod B, whose branched
head 112 is connected by links C, with the upper ends of the crossed levers D D¹,
these latter being fulcrumed in the stationary supporting bars G and having their
lower ends connected through the suspended crossed levers H H', links K K', and
hanger N, with the series of scale weights 1, which form the counterpoise.
The supporting bars G lie parallel with the front E and back F of the standard and
are supported by and fastened to the ledges 100 on the sides thereof. The levers D D¹
are each made double, the two members being connected together by cross bars 101.
The levers H H and the links K K are also made double and have similar cross bars.
The lever D which is placed between the bars G is provided at the middle with
outwardly projecting knife edges 102 which rest in notches 103 in the bars G, (see
Figs. II, VI and VII) and by which the lazy tongs, composed of the parts I) D¹, H'H'
and K K are upheld.
The lever D which is placed between the members of the lever D is provided at
its middle with outwardly projecting knife edges 104 which rest in notches 105 in the
lever D. (sco Figs. VI and VII). The bearings of the knife edges 102 and 104 are
in the same horizontal line.
The knife edges 102 (see also Fig. X) are each formed in one piece with an attaching
plate 205, by bending the said plate and grinding off the projecting portion so as to
leave it of the proper shape for the knife edge. The plates are fastened to the outside
of the lever D, by screws. The knife edges 104 are each formed by grinding one end
of a bar 106. The bodies of the bars (of dovetail form) fit in grooves in the
projections 107 on the inside of the lever D¹ and are secured therein by screws.
The knife edges of both sets are beveled on top (see Fig. VII) so as to leave a point
at the end of each knife edge, and the point is covered by a plate 108 to prevent
endwise motion. The plates 108 for the knife edges 102 are fastened on the outside
of the supporting bars G; those for the knife edges 104 on the outside of the
lever D.
The object of making the knife edges pointed is to avoid friction between them and
the end plates.
It may be here observed that the other knife edges of the lazy tongs (hereafter
more particularly described) are also pointed at their ends and provided with similar
end plates.
The links Care each fixed to a cross bar 110 whose ends, ground to form knife edges,
rest in notches 111 in the upper ends of the levers D D¹ respectively.
The branched head 112 of the scale rod B is provided with notches 113 and rests
upon knife edges 114 at the lower ends of the links C.
Pressure on the scale therefore tends to draw down the beam A, rod B and links C
and to turn the levers D D¹ in opposite directions on their knife edges 102 and 104
respectively.
The lower ends of the levers D D₁ are provided with knife edges 115 and 116
respectively, which are formed on bars 117 and 118 respectively, whose shanks are

page_text: secured in projections 119 and 120 on their respective levers as the bars 106 are
secured to the lever D¹, but at different angles and in different directions, as clearly
represented in the drawings, (see Fig. VII.) The knife edges 115 are turned inward
and project into holes 121 in the upper end of the lever H' which is suspended there-
from; the knife edges 116 are turned outward and project into holes 122 in the upper
end of the lever H, which is suspended from them.
The lever H which is placed between the members of the lever H, is provided
at its middle with outwardly projecting knife edges 123, formed each on the end of a
dove-tailed bar 124, secured in a projection 125 on the inside of the lever. The lever H
is provided at the middle with notches 126 and rests upon knife edges 123 which
enter said notches. The lower ends of the levers H H are precisely like the lower
ends of the levers D D¹, the upper ends of the links K K' are precisely like the upper
ends of the levers H H', and the connection between the levers H H¹ and the links K K',
is precisely like that between the levers D D' and the levers H H¹, so that no further
description is necessary..
The parts at the joints between the levers H H and the links K K¹ are numbered
the same as the corresponding parts of the joints immediately above.
The lower end of the link K is provided with outwardly projecting knife edges 127
which are formed on plates 128 fastened by screws to said link K. They enter the
holes 129 in the ears of the hanger N, which is supported by the said knife edges. The
lower end of the link K¹ which is placed between the members of the link K, is
provided with outwardly projecting knife edges 130 which are secured in projections 131
on the inside of the link.
When therefore the scale rod B is pulled downward the levers D D¹ are turned so
that their ends separate, the levers H H and links K K¹ are lifted and turned and the
hanger N is raised directly upward, the motion of the rod B being multiplied by the
levers or lazy tongs. The motion of the hanger is vertical because the motion of the
knife edges 115 from the centre is exactly compensated for by the motion of the knife
edges 116 in the opposite direction.
The scale weights I are connected with each other so that they are successively
lifted, each scale weight being lifted a certain distance before the next is
engaged.
Such weights are known in various forms. The arrangement preferably employed
is the chain of weights described in my patent No. 9779 of even date herewith, each
scale weight being provided with depending pins which have shanks of suitable length
and are headed at the bottom so that the heads of said pins engage the next weight
after being raised the proper distance.
The upper counterpoise weight of the series or chain I is fastened to the stirrup 132
which forms part of the hanger N, so that as said hanger is raised the weight suspended
therefrom is progressively increased until the pressure exerted through the rod B is
balanced. Each weight of the chain I should counterbalance the same mass on the
scale and to do this should be heavier towards the bottom of the pile.
The weights I are ring shaped and surround the tapering post 133 which is itself
tubular and surrounds the rod B and is fastened to the shelf 134, on which the weights
rest. when not suspended.
The hanger N above the weights I is provided with an automatic friction clutch
(or clutches rather since there are two) for preventing a too rapid motion of the
hanger.
Each clutch is formed by a pivoted sleeve 135 and the fan or wing 136 (see
Figs. I, II and XIV). The two sleeves are arranged one above the other around the
rod B, and are separately journaled in the arms 137 forming part of the hanger. The
fans or wings project in opposite directions and each sleeve is weighted or made
thicker on the opposite side of the pivots from its fan so as to balance the said fan or
wing and hold the same horizontal when the hanger is stationary. When however
the hanger is lifted with sufficient rapidity the pressure of the air on the wings or
fans, turns the sleeves and causes them to clutch the rod B and moderate the motion of
said hanger. The position of the lower clutch when engaging the rod B is indicated

page_text: in dotted lines in Fig. XIV. When equilibrium is established the air pressure is
relieved and the clutches are disengaged. When the hanger is drawn down rapidly,
the clutches are turned in the opposite direction and press against the rod B so as to
moderate the motion. The clutches would of course operate separately, but two are
used in order to act against the rod equally on opposite sides.
The type carrier R in the form of a straight bar is fastened in a vertical position to
the front of the hanger N.
The type S (of metal) are cast separately and are each fastened at the outer end of
a bowed metal spring 138 whose inner end is secured to the carrier R, the same being
clamped firmly against the face of the carrier by the strip 139. Each type is provided
on the back with a tooth 140, (see Figs. IV and V.) The printing finger 141 is
formed on a pin, which is fastened to and projects laterally from the side of the printing
lever L. It is arranged in the space between the type S and the carrier R, (see
Fig. V) so that when moved forward it presses upon and carries with it the type which,
for the time being, happens to be in front of it. The type being carried by the hanger N
are adjusted by the movements of the latter under the influence of the weight on the
scale, and the parts are to be so proportioned and arranged that the number on the
type opposite the printing finger corresponds with the number of pounds on the scale.
The effect of the teeth on the back of the type is that the latter are held from vertical
motion in printing and if the particular type to be printed should be a little above or
below the correct position the finger acting against one of the teeth will force all of the
type up or down until the correct position is attained.
Alongside the printing finger are the wheels M, forming a dating stamp.
The cards 220 upon which the weights are to be printed, are placed horizontally in
a vertical card box P, and presented vertically to the type by means of the feeder
or many sided feed roller Z. This is revolved step by step and has projections 142
each of which in turn catches the card at the bottom of the box, and pushes it
out through an open space 14 at the back of the box into the curved case 144
which holds the cards in place on the roller until after they have passed in front of
the type S and been printed upon, when they are discharged down the incline 145 and
through the slot at the bottom thereof onto the outside shelf 146.
The case 144 opposite the printing finger is cut away so that a type may be
pushed in, to make an impression on the card which, for the time being, is opposite
said finger. Between the type and the feeder Z, is the carbon or ink ribbon Q. It
is held away from the feeder Z and from the edges of the cards by the projections 147,
above and below the cut away portion but can of course be pushed against the cards
between the projections.
The ribbon Q, runs over a pulley 148 at the top of the case and is connected with
the pressure weight or follower 149 which rests upon and is supported by the cards in
the box P. As the cards are removed successively the follower 149 descends by
degrees and moves the ink ribbon so as to present each time a fresh surface for
printing. The ink ribbon is kept stretched by the weight 151 suspended in the
bight of said ribbon, the end of the latter being fastened to the bracket 152 on the
front E of the standard.
The feeder Z is turned step by step, by the pawl 153 carried by the lever arm 199,
fulcrumed on the journal of the feeder Z, said pawl engaging the ratchet 154 fixed on
the said journal. The arm 199 is connected by a link 200 with the printing
lever L. The printing is done on the forward stroke of the lever L, and the pawl
moves the feeder on the return stroke, so that the newly printed card is at once
discharged.
The printing lever is pivoted at 155 to the side of the card box P, and is reciprocated
by the crank pin 156 engaging the slot 157 in the lower end of the lever. The pin 156
projects from the outer face of a pinion 158 which is revolved by the weight T through
an ordinary clock-work, provided with a regulating fan U.
The weight T suspended in the bight of the wire cord 159 which is fastened to
an eye 191 on the top of the standard runs around the pulley 192 on the weight 1,
over the pulley 160 fastened to the top of the standard, and is wound upon the drum 161.

page_text: The spur wheel 162 turns with the drum 161 and the motion is conveyed to the pinion 158
through the pinion 163, shaft 164 and spur wheel 165. The pinion 158 is fast on the
shaft 166 and from this shaft the fan U is driven through the spur wheel 167 fast on
the shaft 166, the pinion 168 and spur wheel 169 loose on the shaft 164 and the
pinion 170 fast on the fan shaft 171.
The various shafts are journaled in bearings of a frame 172 fastened to the front E
of the standard.
Attached to the side of the spur wheel 167 is an escapement disk V having a tooth 173
which engages the tooth 174 on the escapement lever W, and arrests the movement of
the clockwork. The lever W is pivoted at 175 and is provided with an adjustable
counterweight 176 to hold up the tooth 174 in the path of tooth 173; and there are
also stops 177 to limit the motion of the lever.
The front of the lever which may be and is preferably forked so as to retain a coin
of the proper size but to let smaller coins pass through, projects across the lower end
of the spout X, which is suitably cut away to receive the end of the lever, so that a
proper coin passing down the spout will be retained by the lever W and the weight of
said coin overbalancing the lever, will release the clockwork.
The spout X (See Fig. III) is hinged at 176, and is connected by the rod 178 with
the printing lever L. so that as the clockwork revolves, the spout is moved forward and
pushes the coins off of the lever. The coin then drops into the shoot 180, the escape-
ment lever W returns to a position in which it will arrest the clockwork, when the
disk V and crank pin 156 have made one revolution, and the spout X is by the
rotation of the crank pin 156 brought back to its normal position.
Below the shoot 180, is another shoot or passage 181, one side of which is formed
by a transparent pane of glass 182 set in au opening in the front E of the standard,
and a supplemental coin holder J is arranged in the passage so as to stop a descending
coin and hold it exposed to view, until the withdrawal of the coin holder J allows it
to drop.
The shoot or passage 181, communicates with a tube 183 screwed into the top of
the money box 184. The coin holder, which may be and preferably is forked the same
as the escapement lever and for a like purpose, is formed by the end of a lever,
fulcrummed on the shaft 164 and provided at the upper_end_with a pin 185 which
projects into a cat groove 186 in the side of the disk V. The shape of this cam
groove is such that during the first quarter of the revolution the coin holder J is
withdrawn to allow the coin to drop, and is returned to receive a new coin.
The length of the escapement lever W is such that the coin is discharged therefrom
during the second quarter of the revolution after the coin holder has been returned.
Each coin therefore after it has produced its effect on the coin motor, is kept exposed
to view by the supplemental coin holder J; and is discharged when another proper
coin has been introduced into the machine. A stationary knife Y is arranged to
enter a slot in the spout X when this is moved forward and if a string should be
attached to the coin the knife will cut it and allow the coin to drop.
In order to give access to the card box and other parts of the machinery, the upper
part of the front E is hinged at 188, the lower line of division between the movable
and the immovable portion of the front being at 189. In turning the movable part of.
the front E the portion below the hinge 188 moves inward and the part above outward
through a comparatively small angle.
When a person desires to weigh himself with this machine he first steps on the scale
platform. His weight forces down the beam A and rod B, turns the levers D D' H H¹
of the lazy tongs, and lifts the hanger N, raising the weights I successively and
moving the type S in front of the printing finger until equilibrium is established. The
tendency to too rapid motion of the hanger N is resisted by the automatic action
of the clutch sleeves 135.
The type representing the weight of the person, being now opposite the printing
finger, and a card on the feeder Z being in front of the type, a proper coin or token
is to be introduced through the slot 190 (Fig. III) into the spout X. Its fall is
arrested by the escapement lever W, whose front end is borne down releasing the
B

page_text: clock work, which is thereupon revolved by the weight T and moves the printing
lever L forward, through the crank pin 156, so as to press the type against the card
with the ink ribbon Q interposed. The printing finger 141 engages a tooth 140 on the
back of the type and holds the latter from vertical motion with or without first
adjusting it slightly.
After the printing takes place, the printing lever L is returned, the feeder or feed
roller Z is turned one step, discharging the newly printed card, introducing a blank
card in place, and withdrawing a card from the card box P. The withdrawal of the
card allows the follower 149 to move down and shift the ink ribbon Q. During the
first part of the movement of the clock work, the supplemental coin holder J, is with-
drawn to drop the coin previously held thereby, and is then returned in time to
receive the newly introduced coin which is pushed off the escapement lever, W, by
the forward movement of the spout X. The front end of the escapement lever being
relieved of the weight of the coin rises and arrests the clockwork when one revolution
of the disk V and crank pin 156 has been completed.
The coin introduced remains exposed to view behind the glass 182, until the next
coin is introduced, and an attempt to employ a false or counterfeit coin may by this
exposure be detected.
When the person weighed steps off of the scale the lazy tongs are drawn down, the
scale weights I settling down into a pile. A too rapid motion of the parts is prevented
by the automatic action of the clutches on the hanger N.
In Fig. XI instead of connecting the upper ends of the levers D D¹ with the scale
rod B, by depending links C, they are connected therewith by a toggle (*, the scale
rod B being attached to the centre of the toggle by a hanger 207. The arrangement
of the links is preferred; as somewhat steadier.
In Figs. XII and XIII, the supplemental coin-holder is formed by an inclined
shelf 193 in the form of a segment of a hollow cone, provided with a rim 194, for the
coin to rest against. A vertical shaft 195 driven from the shaft 164 through the bevel
gears 202, is provided with wings 196 which sweep over the shelf and discharge the
coin into the tube 183, which leads to the money box. The coins after operating the
coin motor, are each received on the shelf 193, from a spout 197, between the two
wings 196 which at the time are in the proper positions to receive the same, and are
then carried around and exposed to view until discharged into the tube 183. One or
more coins may thus be exposed to view at the same time according to the length of
the shelf and number of wings on the shaft. As the shaft shown has four wings the
gearing for revolving the same is such as to give a quarter turn for each revolution of
the disk V and crank pin 156, and the parts are so arranged that the space between
the wings is brought directly under the spout 197 when the coin is discharged from
the escapement lever W.
The pane of glass 182 in the front E of the standard and just above the shelf 193
enables the coins to be seen.
In order to indicate the results of the weighings to the eye; a graduated scale may
be connected with the type carrier R or the hanger N or with any suitable part of the
lazy tongs so as to be adjusted in position thereby, and inay be arranged to move past
a stationary index; or a movable index may be used'; or any suitable indicating means
may have the movable part thereof connected with or controlled by any suitable part
of the balancing mechanism.
Modifications may be made in details without departing from the spirit of the
invention and parts of the invention may be used separately.
I am aware of Everitt's specification No. 16433 of 1884 and I do not claim any-
thing described and claimed therein.

COMPANY, of New York, in the United States of America, Manufacturers.
I, WILLIAM THOMAS WHITEMAN, of No. 7, Staple Inn, in the County of Middlesex,
Patent Agent, do hereby declare the nature of this invention for "IMPROVEMENTS IN
WEIGHING AND WEIGHT PRINTING MACHINERY AND IN MECHANISM FOR CONTROLLING
WEIGHT PRINTING AND OTHER MACHINERY OR APPARATUS, BY MEANS OF COINS
OR TOKENS," to be as follows
--
This invention relates more particularly to machines for weighing persons and
delivering to them tickets printed with their respective weights, on the introduction
of proper coins or tokens into the machine; but it may in part at least, be otherwise
applied.
First. The invention comprises new or improved means for weighing or balancing
the weight of the persons or objects. For this purpose a system of crossed and jointed
levers like lazy tongs, is employed to convey the pressure, due to the weight of the
person or object, to the scale weights or other balancing appliance or appliances. The
joints of the system of levers are formed by means of knife edges so as to work with
as little friction as may be. A balancing appliance or appliances of any suitable
description may be employed, but it is especially intended to employ a series or chain
of balance or scale weights which are successively lifted until a sufficient number are
suspended to balance the weight of the person or object on the scale. In connection
with such a series of scale weights the aforesaid crossed and jointed levers are
particularly useful as they will give as large a motion as may be desired in a straight
line.
Second. The invention comprises new or improved means for preventing sudden
motion of the scale. For this purpose one or more clutches provided each with a fan
or winged arm, or an equivalent operating contrivance, are mounted on a suitable part
of the scale which has a comparatively large motion, and are arranged to clutch or

page_text: engage another part which has a less motion, or moves in the opposite direction, or is
stationary, so that, for example, when a person steps on or off of the scale, the first
quick motion brings the clutch or clutches into action in consequence of the resistance
to the motion of the fan or fans so that said clutch or clutches check the motion, but
when equilibrium is approached the slow motion or the cessation of movement permits
the fan or fans to resume the normal position and releases the clutch or clutches
leaving the scale free to balance without friction.
Third. The invention comprises new or improved means for adjusting printing type
for recording the results of the weighings. For this purpose the printing type are
mounted on a carrier bar, which is suspended from and moved by the aforesaid system
of crossed and jointed levers. The printing type are supported on the carrier bar by
separate springs or other suitable means, so that they can be pushed out independently
of the said carrier bar and practically of one another; and teeth are provided on the
back of the type or elsewhere, so as to be engaged by an appropriate finger, in order
that the type and carrier may be held in position in printing. It will be understood
that a pointer or some other contrivance could be used to indicate the results of the
weighings to the eye instead of or in addition to the means for recording the said
results.
Fourth. The invention comprises new or improved means for printing the weights,
or results of the successive weighings, upon tickets and for delivering the said
tickets as they are printed. For this purpose in a suitable case below a card box
containing a pile of the tickets there is arranged a feed roller with many sides, which
is so constructed that it withdraws the cards or tickets one at a time from the box and
presents them successively to the printing type, in order that they may receive an
impression from the particular type which the motion of the weighing scale may bring
into position for printing.
The feed roller as well as the printing finger, or means for giving an impression, it
is specially designed to operate by means of a coin controlled clock-work or power
driven mechanism; although the invention is not restricted to that mode of operating
them.
The invention further comprises certain particular constructions and combinations of
the elements herein before or hereinafter mentioned.
In carrying the invention into effect, the crossed and jointed levers are arranged
vertically, the top pair having knife edges which are supported by stationary bearings
and the other levers being suspended from the lower ends of said pair; the scale beam
of an ordinary platform scale is connected by a vertical tension rod with the levers
above the said stationary bearings, so that when the scale beam is depressed the top
pair of levers are turned and the other levers are both turned and lifted after the
manner of the outer levers of lazy tongs; and the series or chain of scale weights
are connected with a hanger suspended by links from the lower ends of levers at the
bottom of the system so that they are lifted vertically. The crossed and jointed levers
are made double to give lateral stiffness and the ends of the knife edges at the joints
are covered by plates which prevent end wise motion, said ends being pointed in order
to reduce the friction to a minimum.
Two automatic clutches are carried by the said hanger and are adapted to engage
the aforesaid tension rod which passes through the hanger. Each clutch consists of a
sleeve pivoted on a horizontal axis and provided with a fan which projects at right
angles from one side and is counterbalanced so that normally the fan is horizontal and
the clutch sleeve vertical. The sleeves surround the tension rod. The two fans
project in opposite directions.
The type carrier in the form of a straight bar is fastened in a vertical position to
the front of the aforesaid hanger. The type (of metal) are cast separately and are
each supported by a bowed metal spring whose opposite end is clamped against the
type carrier. On the back of each type is a tooth. A printing finger, arranged in
the space between the type and the carrier, is moved in the direction to push out a
type and give an impression, by means of a clock work, which is driven by a weight
and is temporarily released by the action of a proper coin or token on a detent or

page_text: escapement lever. The card or ticket to be printed is held by means of the feed
roller and its case in a vertical position in front of the printing finger on the opposite
side of the type therefrom. The back of the case is slotted for the passage of the
type and an interposed ink or carbon ribbon. The feed roller is operated to discharge
the printed card or ticket and to supply a blank card or ticket in its place by means
of the aforesaid clock work.
The supplemental coin holder which receives the coin after it has released the clockwork
is arranged behind a pane of transparent glass so as to hold it in view. It is connected
with the clockwork so as to discharge the coin when the said clockwork is next
released. In one form it is composed of a finger, which extends across a coin shoot or
passage and arrests the descent of the coin when the latter has passed the detent or
escapement for the clockwork, and which is temporarily withdrawn to discharge the
coin, when the clockwork is next released and allowed to revolve, the coin which effects
the release being retained on the detent or escapement lever until the holding finger
has been returned into position to receive it. In another form, it is composed of a
shelf which receives the coins and from which they are removed by one of a series of
radial arms which sweep over the shelf and are moved by the clockwork. It could be
made in a great variety of forms, and adapted to the special machinery which it is
desired to control by means of coins.

Improvements in Weighing and Weight Printing Machinery.
I, WILLIAM THOMAS WHITEMAN, of No. 7, Staple Inn, in the County of Middlesex,
Patent Agent, do hereby declare the nature of this invention for IMPROVEMENTS IN
WEIGHING AND WEIGHT PRINTING MACHINERY, (a communication to me from abroad
by the United States Machine and Inventions Company of New York, in the
United States of America, Manufacturers), 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 more particularly to machines for weighing persons and
delivering to them tickets printed with their respective weights, on the introduction
of proper coins or tokens into the machine; but it has reference also to weighing and
weight printing machinery whether controlled by coins or not.
First. The invention comprises new or improved means for weighing or balancing
the weight of the persons or objects. For this purpose a system of crossed and jointed
levers like lazy tongs, is employed to convey the pressure, due to the weight of the
person or object, from the platform or other support for such person or object, to the
counterpoise composed of scale weights or other balancing appliance or appliances.
The joints of the system of levers are formed by means of knife edges so as to work
with as little friction as may be. A balancing appliance or appliances of any suitable
description may be employed, but it is especially intended to employ a series or chain
of balance or scale weights which are successively lifted until a sufficient number are
suspended to balance the weight of the person or object on the scale. In connection
with such a series of scale weights the aforesaid crossed and jointed levers are
particularly useful as they will give as large a motion as may be desired in a straight
line.
Second. The invention comprises new or improved means for preventing sudden
motion of those weighing scales which have a counterpoise composed of a chain of
connected weights or other appliance or appliances whose balancing effect increases
automatically and progressively with the motion of the scale. For this purpose one
or more clutches provided each with a fan or winged arm, or an equivalent operating
contrivance, are mounted on a suitable part of the scale which has a comparatively
large motion, and are arranged to clutch or engage another part which has a less
motion, or moves in the opposite direction, or is stationary, so that, for example, when
a person steps on or off of the scale, the first quick motion brings the clutch or clutches
into action in consequence of the resistance to the motion of the fan or fans so that
said clutch or clutches check the motion, but when equilibrium is approached the
slow motion or the cessation of movement permits the fan or fans to resume the
normal position and releases the clutch or clutches leaving the scale free to balance
without friction.
Third. The invention comprises new or improved means for adjusting the printing

page_text: type for recording the results of the weighings. For this purpose the printing type
are mounted on a carrier bar, which is suspended from and moved by the aforesaid
system of crossed and jointed levers. The printing type are supported on the carrier
bar by separate springs or other suitable means, so that they can be pushed out
independently of the said carrier bar and practically of one another; and teeth are
provided on the back of the type or elsewhere, so as to be engaged by an appropriate
finger, in order that the type and carrier may be held in position in printing. The
use of teeth attached to type on a yielding support so that the teeth and type would
be pushed out together, constitutes a special feature of invention. It will be under-
stood that a pointer or some other contrivance could be used to indicate the results
of the weighings to the eye instead of or in addition to the means for recording the
the said results.
Fourth. The invention comprises a new or improved combination with or
arrangement in weighing scales having a counterpoise composed of a chain of
connected weights or other appliance or appliances, whose balancing effect increases
automatically and progressively with the motion of the scale, of the weight printing
type, the printing finger or other device for giving the impression and the means for
supplying tickets and presenting them in position for printing and for delivering the
printed tickets; that is to say the combination or arrangement of these parts is such
that the movements of the weighing scale under the pressure of the object weighed
adjust the printing type (which are or may be such as before indicated) in front of a
printing finger, or other device, which moves horizontally to give the impression
while the tickets are taken from an upright card box, wherein they are placed
horizontally, are turned into a vertical position in front of the said horizontally
movable printing finger or other device to receive the impression from the type
under the pressure of said finger or other device and are discharged at once when
printed.
Fifth. The invention comprises new or improved means for printing the weights,
or results of the successive weighings, upon tickets and for delivering the said tickets
as they are printed. For this purpose in a suitable case below a card box containing
a pile of the tickets there is arranged a feed roller with many sides, which is so
constructed that it withdraws the cards or tickets one at a time from the box and
presents them successively to the printing type, in order that they may receive an
impression from the particular type which the motion of the weighing scale may bring
into position for printing.
The feed roller as well as the printing finger, or means for giving an impression,
it is specially designed to operate by means of a coin controlled clockwork or power
driven mechanism; although the invention is not restricted to that mode of operating
them.
The invention further comprises the combination with the balancing and the weight
printing and ticket delivering mechanisms before indicated, of a coin controlled clock-
work or power driven mechanism for operating the same; and also the construction,
combination and arrangement of the knife edges in the system of levers or lazy tongs
for conveying the pressure to the counterpoise, and of the whole machine as illustrated
in the drawings which form part of this specification, and as hereinafter described
with reference thereto.
In the accompanying drawings which form part of this specification,-.

coin holder.
Fig. XIII is a plan of the last mentioned holder; and Fig. XIV is a detailed view
in vertical section of the clutch mechanism.
Referring to the machine as represented in Figs. I-X the lever A of an ordinary
platform scale is connected with the lower end of the scale rod B, whose branched
head 112 is connected by links C, with the upper ends of the crossed levers D D¹,
these latter being fulcrumed in the stationary supporting bars G and having their
lower ends connected through the suspended crossed levers H H¹, links K K', and
hanger N, with the series of scale weights I, which form the counterpoise.
The supporting bars G lie parallel with the front E and back F of the standard and
are supported by and fastened to the ledges 100 on the sides thereof. The levers D D¹
are each made double, the two members being connected together by cross bars 101.
The levers H H' and the links K K¹ are also made double and have similar cross bars.
The lever D which is placed between the bars G is provided at the middle with
outwardly projecting knife edges 102 which rest in notches 103 in the bars G, (see
Figs. II, VI and VII) and by which the lazy tongs, composed of the parts D D', HH¹
and K K are upheld.
The lever D which is placed between the members of the lever D is provided at
its middle with outwardly projecting knife edges 104 which rest in notches 105 in the
lever D. (see Figs. VI and VII). The bearings of the knife edges 102 and 104 are
in the same horizontal line.
The knife edges 102 (see also Fig. X) are each formed in one piece with an attaching
plate 205, by bending the said plate and grinding off the projecting portion so as to
leave it of the proper shape for the knife edge. The plates are fastened to the outside
of the lever D, by screws. The knife edges 104 are each formed by grinding one end
of a bar 106. The bodies of the bars (of dovetail form) fit in grooves in the
projections 107 on the inside of the lever D and are secured therein by screws.
The knife edges of both sets are beveled on top (see Fig. VII) so as to leave a point
at the end of each knife edge, and the point is covered by a plate 108 to prevent
endwise motion. The plates 108 for the knife edges 102 are fastened on the outside
of the supporting bars G; those for the knife edges 104 on the outside of the
lever D.
The object of making the knife edges pointed is to avoid friction between them and
the end plates.
It may be here observed that the other knife edges of the lazy tongs (hereafter
more particularly described) are also pointed at their ends and provided with similar
end plates.
The links C are each fixed to a cross bar 110 whose ends, ground to form knife edges,
rest in notches 111 in the upper ends of the levers D D¹ respectively.
The branched head 112 of the scale rod B is provided with notches 113 and rests
upon knife edges 114 at the lower ends of the links C.
Pressure on the scale therefore tends to draw down the
and to turn the levers D. D¹ in opposite directions on their
respectively.
beam A, rod B and links C
knife edges 102 and 104

page_text: The lower ends of the levers D D' are provided with. knife edges 115 and 116
respectively, which are formed on bars 117 and 118 respectively, whose shanks are
secured in projections 119 and 120 on their respective levers as the bars 106 are
secured to the lever I', but at different angles and different directions, as clearly
represented in the drawings, (see Fig. VII.) The knife edges 115 are turned inward
and project into holes 121 in the upper end of the lever H which is suspended there-
from; the knife edges 116 are turned outward and project into holes 122 in the upper
end of the lever H, which is suspended from them.
The lever H which is placed between the members of the lever H, is provided
at its middle with outwardly projecting knife edges 123, formed each on the end of a
dove-tailed bar 124, secured in a projection 125 on the inside of the lever. The lever H
is provided at the middle with notches 126 and rests upon knife edges 123 which
enter said notches. The lower ends of the levers H Hare precisely like the lower
ends of the levers D D', the upper ends of the links K K' are precisely like the upper
ends of the levers H H', and the connection between the levers H H' and the links K K',
is precisely like that between the levers D D¹ and the levers H H¹, so that no further
description is necessary.
The parts at the joints between the levers H H and the links K K' are numbered
the same as the corresponding parts of the joints immediately above.
The lower end of the link K is provided with outwardly projecting knife edges 127
which are formed on plates 128 fastened by screws to said link K. They enter the
holes 129 in the ears of the hanger N, which is supported by the said knife edges. The
lower end of the link K¹ which is placed between the members of the link K, is
provided with outwardly projecting knife edges 130 which are secured in projections 131
on the inside of the link.
When therefore the scale rod B is pulled downward the levers D D¹ are turned so
that their ends separate, the levers H H and links K K¹ are lifted and turned and the
hanger N is raised directly upward, the motion of the rod B being multiplied by the
levers or lazy tongs. The motion of the hanger is vertical because the motion of the
knife edges 115 from the centre is exactly compensated for by the motion of the knife
edges 116 in the opposite direction.
The scale weights I are connected with each other so that they are successively
lifted, each scale weight being lifted a certain distance before the next is
engaged.
Such weights are known in various forms. The arrangement preferably employed
is the chain of weights described in my patent No. 9779 of even date herewith, each
scale weight being provided with depending pins which have shanks of suitable length
and are headed at the bottom so that the heads of said pins engage the next weight
after being raised the proper distance.
The upper counterpoise weight of the series or chain I is fastened to the stirrup 132
which forms part of the hanger N, so that as said hanger is raised the weight suspended
therefrom is progressively increased until the pressure exerted through the rod B is
balanced. Each weight of the chain I should counterbalance the same mass on the
scale and to do this should be heavier towards the bottom of the pile.
The weights are ring shaped and surround the tapering post 133 which is itself
tubular and surrounds the rod Band is fastened to the shelf 134, on which the weights
rest when not suspended.
The hanger N above the weights I is provided with an automatic friction clutch
(or clutches rather since there are two) for preventing a too rapid motion of the
hanger.
Each clutch is formed by a pivoted sleeve 135 and the fan or wing 136 (see
Figs. I, II and XIV). The two sleeves are arranged one above the other around the
rod B, and are separately journaled in the arms 137 forming part of the hanger. The
fans or wings project in opposite directions and each sleeve is weighted or made
thicker on the opposite side of the pivots from its fan so as to balance the said fan or
wing and hold the same horizontal when the hanger is stationary. When however
the hanger is lifted with sufficient rapidity the pressure of the air on the wings or

page_text: fans, turns the sleeves and causes them to clutch the rod B and moderate the motion of
said hanger. The position of the lower clutch when engaging the rod B is indicated
in dotted lines in Fig. XIV. When equilibrium is established the air pressure is
relieved and the clutches are disengaged. When the hanger is drawn down rapidly,.
the clutches are turned in the opposite direction and press against the rod B so as to
moderate the motion. The clutches would of course operate separately, but two are
used in order to act against the rod equally on opposite sides.
The type carrier R in the form of a straight bar is fastened in a vertical position to
the front of the hanger N.
The type S (of metal) are cast separately and are each fastened at the outer end of
a bowed metal spring 138 whose inner end is secured to the carrier R, the same being
clamped firmly against the face of the carrier by the strip 139. Each type is provided
on the back with a tooth 140, (see Figs. IV and V.) The printing finger 141 is
formed on a pin, which is fastened to and projects laterally from the side of the printing
lever L. It is arranged in the space between the type S and the carrier R, (see
Fig. V) so that when moved forward it presses upon and carries with it the type which,
for the time being, happens to be in front of it. The type being carried by the hanger N
are adjusted by the movements of the latter under the influence of the weight on the
scale, and the parts are to be so proportioned and arranged that the number on the
type opposite the printing finger corresponds with the number of pounds on the scale.
The effect of the teeth on the back of the type is that the latter are held from vertical
motion in printing and if the particular type to be printed should be a little above or
below the correct position the finger acting against one of the teeth will force all of the
type up or down until the correct position is attained.
Alongside the printing finger are the wheels M, forming a dating stamp.
The cards 220 upon which the weights are to be printed, are placed horizontally in
a vertical card box P, and presented vertically to the type by means of the feeder
or many sided feed roller Z. This is revolved step by step and has projections 142
each of which in turn catches the card at the bottom of the box, and pushes it
out through an open space 143 at the back of the box into the curved case 144
which holds the cards in place on the roller until after they have passed in front of
the type S and been printed upon, when they are discharged down the incline 145 and
through the slot at the bottom thereof onto the outside shelf 146.
The case 144 opposite the printing finger is cut away so that a type may be
pushed in, to make an impression on the card which, for the time being, is opposite
said finger. Between the type and the feeder Z, is the carbon or ink ribbon Q. It
is held away from the feeder Z and from the edges of the cards by the projections 147,
above and below the cut away portion but can of course be pushed against the cards
between the projections.
The ribbon Q, runs over a pulley 148 at the top of the case and is connected with
the pressure weight or follower 149 which rests upon and is supported by the cards in
the box P. As the cards are removed successively the follower 149 descends by
degrees and moves the ink ribbon so as to present each time a fresh surface for
printing. The ink ribbon is kept stretched by the weight 151 suspended in the
bight of said ribbon, the end of the latter being fastened to the bracket 152 on the
front E of the standard.
The feeder Z is turned step by step, by the pawl 153 carried by the lever arm 199,
fulcrumed on the journal of the feeder Z, said pawl engaging the ratchet 154 fixed on
the said journal. The arm 199 is connected by a link 200 with the printing
lever L. The printing is done on the forward stroke of the lever L and the pawl
moves the feeder on the return stroke, so that the newly printed card is at once
discharged.
The printing lever is pivoted at 155 to the side of the card box P, and is reciprocated
by the crank pin 156 engaging the slot 157 in the lower end of the lever. The pin 156
projects from the outer face of a pinion 158 which is revolved by the weight T through
an ordinary clock-work, provided with a regulating fan U.
The weight T suspended in the bight of the wire cord 159 which is fastened to

page_text: an eye 191 on the top of the standard runs around the pulley 192 on the weight T,
over the pulley 160 fastened to the top of the standard, and is wound upon the drum 161.
The spur wheel 162 turns with the drum 161 and the motion is conveyed to the pinion 158
through the pinion 163, shaft 164 and spur wheel 165. The pinion 158 is fast on the
shaft 166 and from this shaft the fan U is driven through the spur wheel 167 fast on
the shaft 166, the pinion 168 and spur wheel 169 loose on the shaft 164 and the
pinion 170 fast on the fan shaft 171.
The various shafts are journaled in bearings of a frame 172 fastened to the front E
of the standard.
Attached to the side of the spur wheel 167 is an escapement disk V having a tooth 173
which engages the tooth 174 on the escapement lever W, and arrests the movement of
the clockwork. The lever W is pivoted at 175 and is provided with an adjustable
counterweight 176 to hold up the tooth 174 in the path of tooth 173; and there are
also stops 177 to limit the motion of the lever.
The front of the lever which may be and is preferably forked so as to retain a coin
of the proper size but to let smaller coins pass through, projects across the lower end
of the spout X, which is suitably cut away to receive the end of the lever, so that a
proper coin passing down the spout will be retained by the lever W and the weight of
said coin overbalancing the lever, will release the clockwork.
The spout X (See Fig. III) is hinged at 176, and is connected by the rod 178 with
the printing lever L, so that as the clockwork revolves, the spout is moved forward and
pushes the coins off of the lever. The coin then drops into the shoot 180, the escape-
ment lever W returns to a position in which it will arrest the clockwork, when the
disk V and crank pin 156 have made one revolution, and the spout X is by the
rotation of the crank pin 156 brought back to its normal position.
Below the shoot 180, is another shoot or passage 181, one side of which is formed
by a transparent pane of glass 182 set in an opening in the front E of the standard,
and a supplemental coin holder J is arranged in the passage so as to stop a descending
coin and hold it exposed to view, until the withdrawal of the coin holder J allows it
to drop.
The shoot or passage 181, communicates with a tube 183 screwed into the top of
the money box 184. The coin holder, which may be and preferably is forked the same
as the escapement lever and for a like purpose, is formed by the end of a lever,
fulcrumed on the shaft 164 and provided at the upper end with a pin 185 which
projects into a cam groove 186 in the side of the disk V. The shape of this cam
groove is such that during the first quarter of the revolution the coin holder J is
withdrawn to allow the coin to drop, and is returned to receive a new coin.
The length of the escapement lever W is such that the coin is discharged therefrom
during the second quarter of the revolution after the coin holder has been returned.
Each coin therefore after it has produced its effect on the coin motor, is kept exposed
to view by the supplemental coin holder J; and is discharged when another proper
coin has been introduced into the machine. A stationary knife Y is arranged to
enter a slot in the spout X when this is moved forward and if a string should be
attached to the coin the knife will cut it and allow the coin to drop.
In order to give access to the card box and other parts of the machinery, the upper
part of the front E is hinged at 188, the lower line of division between the movable
and the immovable portion of the front being at 189. In turning the movable part of
the front E the portion below the hinge 188 moves inward and the part above outward
through a comparatively small angle.
When a person desires to weigh himself with this machine he first steps on the scale
platform. His weight forces down the beam A and rod B, turns the levers DD' H H¹
of the lazy tongs, and lifts the hanger N, raising the weights I successively and
-moving the type S in front of the printing finger until equilibrium is established. The
tendency to too rapid motion of the hanger N is resisted by the automatic action
of the clutch sleeves 135.
The type representing the weight of the person, being now opposite the printing
finger, and a card on the feeder Z being in front of the type, a proper coin or token
R

page_text: is to be introduced through the slot 190 (Fig. III) into the spout ✗. Its fall is
arrested by the escapement lever W, whose front end is borne down releasing the
clock work, which is thereupon revolved by the weight T and moves the printing
lever I forward, through the crank pin 156, so as to press the type against the card
with the ink ribbon Q interposed. The printing finger 141 engages a tooth 140 on the
back of the type and holds the latter from vertical motion with or without first
adjusting it slightly.
After the printing takes place, the printing lever L is returned, the feeder or feed
roller Z is turned one step, discharging the newly printed card, introducing a blank.
card in place, and withdrawing a card from the card box P. The withdrawal of the
card allows the follower 149 to move down and shift the ink ribbon Q. During the
first part of the movement of the clockwork, the supplemental coin holder J, is with-
drawn to drop the coin previously held thereby, and is then returned in time to
receive the newly introduced coin which. is pushed off the escapement lever, W, by
the forward movement of the spout X. The front end of the escapement lever being
relieved of the weight of the coin rises and arrests the clockwork when one revolution
of the disk V and crank pin 156 has been completed.
The coin introduced remains exposed to view behind the glass 182, until the next
coin is introduced, and an attempt to employ a false or counterfeit coin may by this
exposure be detected.
When the person weighed steps off of the scale the lazy tongs are drawn down, the
scale weights I settling down into a pile. A too rapid motion of the parts is prevented
by the automatic action of the clutches on the hanger N.
In Fig. XI instead of connecting the upper ends of the levers D D¹ with the scale
rod B, by depending links C, they are connected therewith by a toggle C*, the scale
rod B being attached to the centre of the toggle by a hanger 207. The arrangement
of the links is preferred, as somewhat steadier.
In Figs. XII and XIII, the supplemental coin-holder is formed by an inclined
shelf 193 in the form of a segment of a hollow cone, provided with a rim 194, for the
coin to rest against. A vertical shaft 195 driven from the shaft 164 through the bevel
gears 202, is provided with wings 196 which sweep over the shelf and, discharge the
coin into the tube 183, which leads to the money box. The coins after operating the
coin motor, are each received on the shelf 193, from a spout 197, between the two
wings 196 which at the time are in the proper positions to receive the same, and are
then carried around and exposed to view until discharged into the tube 183. One or
more coins may thus be exposed to view at the same time according to the length of
the shelf and number of wings on the shaft. As the shaft shown has four wings the
gearing for revolving the same is such as to give a quarter turn for each revolution of
the disk V and crank pin 156, and the parts are so arranged that the space between
the wings is brought directly under the spout 197 when the coin is discharged from
the escapement lever W.
The pane of glass 182 in the front E of the standard and just above the shelf 193
enables the coins to be seen..
In order to indicate the results of the weighings to the eye, a graduated scale may
be connected with the type carrier R or the hanger N or with any suitable part of the
lazy tongs so as to be adjusted in position thereby, and may be arranged to move past
La stationary index; or a movable index may be used; or any suitable indicating means
may have the movable part thereof connected with or controlled by any suitable part
of the balancing mechanism.
Modifications may be made in details without departing from the spirit of the
invention and parts of the invention may be used separately.
