Improvements in Self Collecting and Checking of Tolls for and
Controlling the Use of Weighing Machines and Dynamometers.
I HENRY KNIGHT of the Arcade, Ryde Isle of Wight in the county of Southampton
Importer of Italian Sculptures do hereby declare the nature of my invention for
IMPROVEMENTS IN SELF COLLECTING AND CHECKING OF TOLLS FOR & CONTROLLING
THE USE OF WEIGHING MACHINES & DYNAMOMETERS to be as follows:-
:-
My invention consists of the improvements hereinafter described viz.-a more
complete and compact way of arranging and applying the parts of suitable mechanism
to self collecting of Tolls which admits of being adjusted to act by any weight of
metallic coin or coins that may be charged for its use, and which also registers the
number of times the machine is used by an index counter connected to a four armed
fan, the said fan being caused to revolve in a shoot by the weight of the coin as it falls
after being placed in the slot,-It may be fixed to receive the coin above or below the
hopper.
My invention is especially suited to the well known "Salter" make of Spring
Balance weighing machines, and it may also be applied to other suitable weighing
machines.
The spring balance platform weighing machine as ordinarily constructed consists
essentially, of a cast iron column, with frame at top for attaching the coiled spring
rack and pinion, a graduated dial is also fixed to the frame in front, and one end of the
pinion spindle passes through the centre of dial, to which is fixed a traversing finger
to indicate the weight.
The platform frame has four knife edged bearings, to carry the weighing gear, and
the platform.
The weighing gear consists of two frame pieces, one piece having an arm extending
to the base of the upright column, a rod attached to the springs, &c., and is hooked into
the said arm.
The two aforesaid frame pieces are provided with four knife edged
bearings each, and are coupled together in the centre, two of the said knife edged
bearings on each frame piece are for the purpose of hanging them in the frame, and
the other two each are for the platform to bear on.

page_text: According to my improvements I make a revolving, reciprocating dial, marked on
the face or on the peripher in pounds, stones, or other figures to show the weight. I
fix a pointer, in a suitable position, so that when a weight is placed on the platform,
the dial will revolve, and stop at the pointer, and indicate the weight of the body placed
on the platform.
By this means persons weighing themselves will be able to ascertain their weight
more correctly and much more conveniently.
The platform of the machine I cover with India-rubber.
I fix a revolving four armed fan provided with ratchet and catch, in the shoot
which carries the coin from the slot to the hopper to prevent persons liberating the
weighing gear by any unfair means. The shoot is grooved and has a shifting slide,
by means of which, you may regulate the size of coin to be taken as toll, it also
has a shutter underneath, which if shut will allow all coins to pass into the
hopper but which if open and the groove slide set to reject small coin, they will fall
through.
1 stop the action of the weighing gear that is underneath the platform, so that until
the toll is paid the machine cannot be used.
I provide the means for fixing and varying the amount of money to be paid for
the use of the machine, by a shifting balance weight on one part of a T shaped beam,
it can be set so that a small coin will liberate the aforesaid weighing gear, or it
may be set to require a larger coin, or several coins, to liberate the aforesaid weighing
gear.
According to one of my improvements for unlocking and locking the weighing gear,
I use the usual locking rod, for throwing the machine in and out of gear (but not one
fourth its length) in connection with a can piece, having three arms, and two
projecting spindles a hole for the fulcrum pin, and is pinned to a plate of metal by the
fulcrum pin and the said plate of metal itself is fixed to the upright column at its base
either in front or at the back, the head or vertical part of the cam piece, has a part of
a radius with a notch cut at the lower part to admit the end of a lever and just about
a quarter of an inch below this notch. is a projecting stud, and about one inch above
the fulcrum pin, and one eighth of an inch out of the vertical line of the fulcrum pin,
and one end of the rod has an eye, and fits on the said stud and is kept there by
screw and washer. The other end is attached to the extending arm of the weighing
gear, by a nut screw and washer, the nut and washer being under the arm and allows
the rod to fall freely to throw the machine into gear.
al
One arm of the cam projects in a line with the, fulerum at an angle of about 45
(which arm 1 will call the lever arm of the cam) the other arm of the cam piece
extends in the opposite direction, and extending a little beyond the fulcrum pin of the
horizontal lever and the point is about one sixteenth of an inch below the lever, to
prevent the lever when weighted with money. from falling more than sufficient to
raise the other end of the lever out of the notch of the cam, and the said lever is
pinned to the aforesaid plate of metal in a horizontal line to the cam notch and of a
sufficient distance to allow the cam head to pass when it is turned on its fulcrum. And
on one end of the lever is a platform with a round hole, and any money smaller in
diameter than a penny will fall through, and not act on the lever-but the same end
of the lever has also a hinged flap to cover the hole when necessary, so that no coin
shall fall through.
If the Toll is fixed at a halfpenny two farthings will act on the lever the same as a
halfpennny, and if the Toll is a penny, two halfpennies or four farthings will act on the
lever the same as a penny would do.
The other end of the lever rests in the notch of the cam piece, and it also has a
shifting balance weight with set screw, this balance weight can be set, so that the
amount of money, as a Toll, must be of a certain amount that will be sufficient to act
on the lever to lift its end out of the notch of the cam piece.
To unlock the weighing gear a tee shape lever with two spindles one on each end of
the horizontal part at its lower end, moves on bearings fixed to the frame of the plat-
form but under the platform itself, and the right angle end of the tee lever is under

page_text: the lever arm of the cam piece-or it may be slotted and the lever arm of the cam pass
into the slot or it may be connected by a piece of metal having two slots one slot
vertical and the other horizontal.
The end of the tee lever is slotted and fitted into the vertical slot and a pin passing
through the slots and pinning them together, a pin having a round flat head which,
passes through the horizontal slot and is fixed into the lever arm of the cam piece,
thus pinning them together, the horizontal slot moves on this pin, and the slot in the
tee lever moves on the pin through the slot.
The platform frame having four legs standing on the knife edged bearings of the
weighing gear, and the bearings of the tee lever are on the frame of the
platform.
The platform is hinged to the frame above the tee lever at the nearest the column,
the other end resting on a counter balance weight that is fixed to the frame, or
under the platform, or two springs to balance the weight of the platform, so as not to
press on the horizontal part of the tee lever and a counter balance weight is also fixed
to the lever arm of the can piece to give the back action.
When the platform is not of iron cover it with fluted india rubber.
I fix a piece of wood or metal to the frame of the machine, and close to the platform,
a few inches high (but so as not to touch it) on each side and on the end nearest the
column, to prevent other persons putting their foot on the platform when persons are
being weighed.
The action of the machine will be-on the amount of the Toll in money being put
into the conducting tube, its weight on the platform of the lever, will cause the lever
to drop on the cam arm and there stop, the other end of the lever will be raised out of
the notch of the cam head-and on a child or person then standing on the platform of
the machine, their weight will cause the horizontal part of the tee lever to heel over
and raise the right angle part which will raise the lever of the cam and cause the cam
to move round on its fulcrum pin, and the radius part of the cam head will then lift
the end of the horizontal lever. and tip the money off its platform, at the same time
the rod will be lowered, and the weighing gear free to move, and the weight of the
person will be indicated on the dial by the pointer finger. As soon as the person
gets off the platform, the back action is obtained by the counter balance weights
on the lever arm of the cam, and the other arm of the cam under the horizontal lever,
will force this lever back into the notch of the cam, and the shifting balance weight
on the lever will keep it in the notch until the operation is repeated.
The cam has a rotary reciprocating motion, which rises and carries the locking rod
back, and the weighing gear is locked-and in its forward action it lowers the rod,
and sets the weighing gear free to move.
According to another of my arrangements, I dispense with the loose locking rod, as
described in my first arrangement- substitute in its place a fixed one to the
extended arm of the weighing gear-It consists of a flat piece of metal, having two
projecting guide pins, one on each edge, and a hole in the centre to receive a hook,
and a short rod projecting from the flat surface upwards, has a projecting hook-It is
fixed to the extending arm of the weighing gear in an upright position, passing through
the frame of the machine close to the base of the column. At the base of the column,
the mechanism is fixed to a piece of metal, or framed pieces.
The mechanism consists of a tee shaped beam, with two projecting fulerum spindles
one on each side, in advance, of the vertical part-one end of the horizontal part has
a hopper fixed, and the other end a shifting balance weight, with set screw, the vertical
part having a projecting hook-The spindles work on knife edged bearings fixed to
the piece of metal or frame work.
A disc of metal with two slots one at right angles and the other vertical (below the
centre) pinned to the frame work about one and a half inches above the tee shape
beam and in advance about one inch of the projecting spindles.
The aforesaid projecting hook, on the short rod, works in the right angle slot of the
disc.
A cranked lever is pinned to the tee shape beam, the crank end of the lever works

page_text: into the vertical slot. The other end of the lever comes under the hopper and forms
the bottom, and is connected to the fulcrum pin under the beam by a nut on a square
shoulder, but this end is slotted to allow the lever to he lengthened or shortened for
receiving different sized coin. If extended no coin will fall through, if shortened
small coin will fall through and not operate. The cranked part of the lever is fixed
on the fulcrum pin above the beam.
The action of the lever is reciprocatory on a horizontal plain, and if used above the
tee shape beam and a platform used in place of a hopper, it will sweep the
the platform into a drawer below.
money off
The action of the mechanism will be as follows-When the tee shape heam is at
rest, the hook on the vertical part will be through the hole of the flat piece of metal
and the machine is locked.-On the amount of the Toll being placed in the shoot,
which will conduct it to the hopper, that part of the beam will be weighed down, and
at the same time, the hook on the vertical part will be drawn out of the hole, and the
machine is unlocked and free to move, and a person standing on the platform will
cause the projecting hook in the right angle slot to lower, and to pull the disc round
its fulcrum pin, the vertical slot at the same time will move the crank lever, and
the money will fall through the hopper, or be swept off the platform as the case
might be.
On the person leaving the platform the back action will be from the coil springs,
the pin in the right angle slot forces the disc back, carrying the crank lever with it
and the counter balance weight on the beam, will cause that part of the beam to fall,
and carry the hook on the vertical part through the hole, and the machine will be
locked, and will remain so until the operation is repeated.
According to another of my improvements, I make a tee shape beam which has
knife edge (or round) spindles projecting from it on each side, in a straight line. of
the vertical part of the lever, and the extreme end of the vertical part works in a
slotted bolt which is kept in its position by a guide piece, and on one end of the
horizontal part is a sliding balance weight with a set screw, and on the other end of
the horizontal part is a hopper, and a crank lever with a tee shape slide, the lower
part of the hopper is formed to receive a tee slide piece which has two slots, one slot
horizontal, the other vertical, and the cranked lever on one end has a projecting pin,
the other end is slotted.
The lever is pinned to the tee shape beam about one inch in advance of its spindle
bearings, and the action is right angle reciprocating motion.
The slotted end of the lever is on the projecting pin of the upright piece that is
fixed to the extending arm of the aforesaid weighing gear, the pin at the other end
of the lever is in the vertical slot of the slide, the horizontal part of the slide is in its
place under the hopper-The position of the tee shape beam when at rest is as
follows The bolt at the end of the vertical part will be passed through the hole of
the upright piece, fixed to the extending arm of the aforesaid weighing gear, but as
soon as the amount of Toll in money is placed into the hopper, that end of the lever
will fall to a stop sufficient for the vertical part to withdraw the bolt from the said hole
and set the weighing gear free to move.
The motor that moves the cranked lever is the weight on the platform which presses
down the extending arm of the weighing gear and carries the upright piece that is
fixed with it, moving the projecting pin in the said slot causes the lever to move
round its fulcrum pin, the pin at the other end of the lever being in the vertical slot
of the tee slide piece is moved forward under the hopper, and the money falls through
into a drawer below.
The motor of the back action is from the two coiled springs-As soon as the weight
is removed from the platform the pin in the slotted end of the lever moves upwards,
and the lever is forced upwards to its starting point, and the tee slide is moved back
to its starting point, then the tee shape beam will by the sliding balance weight cause
it to return to its starting point, and the bolt at its vertical end passes into the hole and
locks the weighing gear.
According to another of, my improvements I make a tee shape beau, which has a

page_text: knife edged or round projecting spindles from it on each side in a straight line with
the vertical part of the beam, and a hole is formed in it about half an inch from the
end, and at the extreme end below the hole it is bevelled from the inner to the outer
edge. The tee shape beam has a hopper on one end of the horizontal part, and the
other end of the horizontal part has a sliding balance weight with a set screw.
The flat piece of metal as in the other arrangements, is fixed to the extending arm
in an upright position, but in this arrangement it has four projecting pins, two act as
guides, one on the flat surface passes into the hole on the vertical part of the tee
beam, the other is below the guide pin and flush with the edge of the metal-the
metal being cut away sufficiently to allow the slotted end of the lever to move on
this pin freely.
A crank lever one end slotted is pinned to the tee beam about one inch in advance
of its projecting spindles, or it may have its fulcrum pinned to the frame of the
machine.
The slotted end of the lever is on the aforesaid pin, the other end is under the
hopper, the hopper has a round bottom, weighted on one side and rests on a stop, and
works on two projecting spindles.
When the tee beam is at rest the projecting pin on the flat surface will be through
the hole in the vertical part of the beam, and the machine gear will be locked.
As soon as the amount of money in Toll is placed into the hopper, that end of the
beam will fall to a stop sufficient to raise the vertical part and to withdraw the hole.
from the pin, and to unlock the weighing gear, and it will then be free to move, and
as soon as any weight is on the platform the slotted end of the lever on the pin will
move, and at the same time, the other end under the hopper will tilt upwards, and
turn the bottom-up, and the money will fall out into a drawer below.
The action of the lever is reciprocating the back action being from the two coiled
springs. As soon as the weight is off the platform, the horizontal part of the tee
beam, by its counter balance weight, will fall and the hole in the vertical part will
pass on the pin, and so lock the weighing gear, and the slotted lever will at the same
time he carried back to its starting point, and the bottom of the hopper will fail to its
resting place and remain so until the operation is repeated.
According to another of my improvements I apply the tee shape beam direct under
the extending arm of the weighing gear, and so dispense with the short upright
piece, the fulcrum bearings of the beam will be fixed to the machine frame, the beam
will have a platform instead of a hopper, and a shifting counter balance weight and
projecting spindles (as the others) the beam bearing will be fixed under the centre of
the extending arm of the weighing gear the vertical part of the beam being upwards,
and under the centre of the arm of the weighing gear and against a stop, but will not
quite touch the arm, so that it may be free to move on the money being placed on the
platform, and as soon as the money is on the platform the weight will cause that part
of the beam to fall to a stop, and the point of the vertical part of the beam will, at
the same time, be removed from under the arm, and the weight on the platform will
cause the arm to move downwards and either one of the arrangements for removing
the money off the platform can be applied to this arrangement, and on a person
leaving the platform the tee lever will resume its back action by the counter balance,
and so lock the weighing gear.
According to another of my improvements I make the dial to move and dispense
with the traversing finger.
I give the required rotary reciprocating motion to the indicating dial by using the
usual two coiled springs with rack pinioned spindle, the carrier is a flat piece of metal
with two slots horizontal, one at each end, the centre has a round projecting boss on
one side, the said boss has a square hole through its centre, to fit the square part on
the spindle, and the dial has a round hole in its centre to admit the boss to pass
through, and the square hole in the boss passes on to the square part of the spindle,
and is kept there by a nut and screw on key pin, this end will rest on an arbor
bearing, the shank end of a flat headed screw, is passed through each slot and
screwed into the dial, and so connecting the dial to the spindle, the two slots are

page_text: for the purpose of allowing and shifting the dial to zero, before it is screwed up
tight.
I fix a finger pointer to the frame at the top, close to the indicating dial-the
dial will revolve to this point, and show the weight that is on the platform of the
machine.
I fix suitable guide pieces, to the frame, to keep the dial steady, or a groove if
necessary, and I fix an india-rubber or other suitable stop, to stop the dial in its back
sudden movement from passing the point zero, and prevent any jar.
I cover the face of the dial with glass in a frame hinged with lock and key, or it
may be screwed on.
The dial may be made of any suitable light metal, wood, vulcanite, india rubber or
papier machiè, or the like with or without enamel.
The action will be the teeth of the rack will engage the tooth wheel or pinion on
the spindle, and the spindle will turn carrier or driver and so turn the dial,
:
I make a suitable cast iron frame with all necessary bearings for fixing and carrying,
and cover in all the mechanism applied to the weighing machine. The frame also
has two sides and one end, a few inches above the platform to prevent other persons
putting their feet on the platform when a person is being weighed.
The frame has four wheels, and four scrow legs, the object of the screw legs, is to
keep and set the machine level, and from moving when in its place, the legs can bo
screwed up or down to fit the floor, and to take the weight off the wheels.
The said teo shape beam with the combined mechanism can be applied to other kinds
of weighing machines having other springs than coiled.
It can also be applied to beam, or any suitably constructed weighing machines with
or without a platform.
The mechanism applies equally to weighing machines that have a fixed indicator,
dial, and a traversing finger.
The mechanism with the rotary reciprocating dial, or a fixed dial with traversing
finger, may be applied to any convenient part of a spring dynamometer, especially to
test the strength of persons for the same purpose and same object (viz. to lock and
unlock the action of the machine, and to collect the Toll) and the two may be fixed
to the same frame or fixed separately.

page_text: Improvements in Self Collecting and Checking of Tolls for and
Controlling the Use of Weighing Machines and Dynamometers.
I HENRY KNIGHT of the Arcade Ryde, Isle of Wight in the County of Southampton,
Importer of Italian Sculptures 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 consists of the improvements hereinafter described viz.-A more
complete and compact way of arranging and applying the parts of suitable mechanism
to self collecting of Tolls which admits of being adjusted to act by any weight of
metallic coin or coins that may be charged for its use, and which also registers the
number of times the machine is used by an index counter connected to a four armed
fan, the said fan being caused to revolve in a shoot by the weight of the coin as it
falls after being placed in the slot. It may be fixed to receive the coin above or
below the hopper.
In the said registering apparatus I use the same kind of counters as are used in
some Gas meters and check registering apparatus, with my addition thereto -that is a
grooved shoot, a four armed fan, tooth ratchet wheel and catch. I construct a suitable
frame so as to combine my additions with the registering device. The counters are
usually made of wood with brass toothed wheel fixed on one side, and on the other
one projecting tooth. Each counter has ten numbers marked on its periphery that is
1. to 0; use four of these counters and one brass tooth driving wheel loose on the
same shaft, the driving wheel is keyed to the shaft. The bearings of the shaft are
through the sides of the frame, the shaft projects beyond the bearings and on one end
is fixed a ratchet wheel and a catch pinned to the frame so that it can act on the
ratchet whicel to prevent the back action and on the other end of the shaft is keyed a
four armed fan, the arm projecting through the grooved shoot, the shoot is cut away
sufficiently to allow the arms of the fan to revolve through it, the coin is kept in its
place by the groove. Four pinion wheels are arranged on one shaft loosely, the shaft
is fixed to the frame so that one pinion comes between each counter that it may gear
with the counter in its proper turn.
•
The action will be on the coin being put into the slot it will run down the grooved
shoot and on the arm of the fan and by its weight cause the fan to revolve a quarter
of a revolution and the first counter that is geared to the driving wheel will then
partly revolve and show the figure 1. the next operation the same counter will move
and show the number 2. and so on until the tenth operation, when the first counter
comes into gearing with the second counter by its projecting tooth, and first pinion,
in this tenth operation the first counter shows 0. the second shows the figure I so the
two counters together show the number 10. and proves that ten operations have taken
place; the next operation the first counter only will move and show the figure 1. so
the two counters together will show the number 11. and so on the numbers being
shown at each operation by the two counters and on the twentieth operation the two
counters come into gearing again and both move together the first counter showing 0.
the second showing 2. so the two counters together show the number 20 and so proves

page_text: that twenty operations have taken place. The first counter moves at every operation,
the second at every tenth, the third at every hundredth, the fourth at every thousandth
so that the apparatus will register from 1 up to 9,999. The first counter remains
always in gear but the other three counters come in and out of gearing as they revolve
to show their number.
The figures on the four counters reckon as units, tens, hundreds, and thousands.
My invention is especially suited to the well known "Salter or Pooley make of
Spring Balance Weighing Machines, and it may also be applied to other suitable
weighing machines.
The spring balance platform weighing machine as ordinarily constructed consists
essentially, of a cast iron column, with frame at top for attaching the coiled spring
ruck and pinion, a graduated dial is also fixed to the frame in front, and one end of
the pinion spindle passes through the centre of dial, to which is fixed a traversing
finger to indicate the weight marked on the dial in pounds and stones.
The platform frame has four knife edged bearings, to carry the weighing gear and
the platform.
The weighing gear consists of two frame pieces, one piece having an arm extending
to the base of the upright column, a rod attached to the springs, &c., is hooked in to
the said arm. The two aforesaid frame pieces are provided with four knife edged
bearings each, and are coupled together in the centre, two of the said knife edged
bearings on each frame piece are for the purpose of hanging them in the frame, and
the other two each are for the platform to bear on. The aforesaid frame pieces are
known as the compound levers.
According to my improvements I make a revolving, reciprocating dial, marked on
the face, or on the periphery in pounds, stones, or other figures to show the weight, I
fix a pointer, in a suitable position, so that when a weight is placed on the platform,
the dial will revolve, and stop at the pointer, and indicates the weight of the body
placed on the platform.
By this means persons weighing themselves will be able to ascertain their weight
more correctly and much more conveniently.
The platform of the machine I cover with india-rubber to prevent persons
slipping.
TFx a revolving four armed fan provided with ratchet and catch, in the shoot
which carries the coin from the slot to the hopper to prevent persons liberating the
weighing gear by any unfair means. The shoot is grooved and cut away sufficiently
to allow the fan arms to revolve through it and has a shitting slide, by means of
which, you may regulate the size of coin to be taken as Toll, it also has a shutter
underneath, which if shut will allow all coins to pass into the hopper but which if open
and the groove slide set to reject small coin, they will fall through. And may be
conducted by a shoot to the drawer below on the opposite side or in any other
direction.
The action will be-on a person putting a coin or coins into the slot it will fall on that
arm of the said fan, that is projecting through the shoot and by its weight it will cause
the fan to revolve sufficiently to allow the coin to pass onward in its groove, and so
conduct it to the hopper, or platform as the case may be the fan makes one quarter
of a revolution at each operation-that is four operations will make a complete
revolution of the fan-The ratchet wheel and catch prevent the back action.
When a person instead of using a coin or coins adopts the known unfair means of
attempting to liberate the mechanism by pushing the coin rreeptacle down by the use
of a strip of cardboard, or whalebone, or thin flat steel, or the like, he will be
disappointed for such will not pass the fan but will be stopped, and held fast by the
said arm of the fan, in its downward movement and so prevent the fan making a
quarter of a revolution, which is absolutely necessary to allow it to pass but the
false means will be easily pulled back, and the fan will not be damaged by the
attempt.
When the said fan is used with a shoot having but one groove it will work the same
but in that case all size coins will be received and operate and turn the fan, but

page_text: nevertheless will not move the locking lever until the weight in coin or coins makes
up the amount of Toll set.
I stop the action of the weighing gear that is underneath the platform, so that until
the Toll is paid the machine cannot be used.
I provide the means for fixing and varying the amount of money to be paid for the
use of the machine, by a shifting balance weight on one part of a Teo shaped beam, it
can be set so that a small coin will liberate the aforesaid weighing gear, or it may
be set to require a larger coin, or several coins to liberate the aforesaid weighing
gear.
gear,
According to one of my improvements for unlocking and locking the weighing
I use the usual locking rod, for throwing the machine in and out of gear (but
not one fourth its length) in connection with a cam piece, having three arms and two
projecting spindles, a hole for the fulcrum pin and is pinned to a plate of metal by the
fulcrum pin and the said plate of metal itself is fixed to the upright column at its base
either in front or at the back, the head or vertical part of the cam piece, has a part of
a radius with a notch cut at the lower part to admit the end of a locking lover arm
just about a quarter of an inch below this notch and about one inch above the fulcrum
pin and one eighth of an inch out of the vertical line of the fulcrum pin is a projecting
stud, and one end of the rod has an eye, and fits on the said stud and is kept there by
a screw and washer.
The other end is attached to the extending arm of the weighing gear, by a nut,
screw and washer, the nut and washer being under the arm and allows the rod to fall
freely to throw the machine into gear.
One arm of the cam projects in a line with the fulcrum at an angle of about 45,
(which arm I will call the lever arm of the cam) the other arm of the cam piece,
extends in the opposite direction, and extending a little beyond the fulcrum pin of the
horizontal lever and the point is about one sixteenth of an inch below the lever, to
prevent the lever when weighted with money from falling more than sufficient to raise
the other end of the lever out of the notch of the cam, and the said lever is pinned to
the aforesaid plate of metal in a horizontal line to the cam notch and of a sufficient
distance to allow the cam head to pass when it is turned on its fulcrum. And on one
end of the locking lever is a platform with a round hole, and any money smaller in
diameter than a penny will fall through, and not act on the lever, but the same end
of the lever has also a hinged flap to cover the holo when necessary, so that no coin
shall fall through.
If the Toll is fixed at a halfpenny two farthings will act on the locking lever the
same as a halfpenny, and if the Toll is a penny, two halfpennies or four farthings will
act on the lever the samo as a penny would do.
The other end of the lever rests in the notch of the cam piece, and it also has a
shifting balance weight with set screw, this balance weight can be set so that the
amount of money as a Toll must be of a certain amount that will be sufficient to act
on the lever, to lift its end out of the notch of the cam piece.
To unlock the weighing gear a Tee shape lever with two spindles one on each end
of the horizontal part at its lower end, moves on bearings fixed to the frame of the
platform but under the platform itself, and the right angle end of the Tec lever is
under the lever arm of the cam piece-or it may be slotted and the lever arm of the
cam pass into the slot-or it may be connected by a piece of metal having two slots,
one slot vertical and the other horizontal. I prefer the last method.
The end of the Tee lever is slotted and fitted into the vertical slot and a pin passing
through the slots and pinning them together, a pin passes through the horizontal slot
and is fixed into the lever arm of the cam piece, thus pinning them together, the
horizontal slot moves on this pin, and the slot in the Tec lever moves on the pin through
the slot.
The platform frame having four legs standing on the knife edged bearings of the
weighing gear, and the bearings of the Tee lever are on the frame of the platform.
The platform is hinged to the frame above the Tec lever at the end nearest the
column, the other end resting on a counter balanco weight that is fixed to the frame,

page_text: or under the platform, or two springs to balance the weight of the platform, so as not
to press on the horizontal part of the Tee lever and a counter balance weight is also
fixed to the lever arm of the cam piece to give the back action.
When the platform is not of iron I cover it with fluted india rubber.
I fix a piece of wood or metal to the frame of the machino and close to the platform
a few inches high (but so as not to touch it) on each side and on the end nearest the
column, to prevent other persons putting their foot on the platform when persons are
being weighed.
The action of the machine will be-on the amount of the Toll in money being put
into the conducting tube, its weight on the platform of the locking lever, will cause the
lover to drop on the cam arm and thero stop, the other end of the lever will be raised
out of the notch of the cam head-and on a child or person then standing on the
platform of the machine, their weight will cause the horizontal part of the Tee lever to
heel over and raise the right angle part which will raise the lever of the cam and cause
the cam to move round on its fulcrum pin, and the radius part of the cam head will
then lift the end of the horizontal lover, and tip the money off its platform, at the samo
time the rod will be lowered, and the weighing gear free to move and the weight of
the person will be indicated on the dial by the pointer finger. As soon as the person
gets off the platform the back action is obtained by the counter balance weights on the
lever arm of the cam, and the other arm of the cam under the horizontal lever will
force this lever back into the notch of the cam, and the shifting balance weight on the
lever will keep it in the notch until the operation is repeated.
The cam has a rotary reciprocating motion which rises and carries the locking rod
back and the weighing gear is locked-and in its forward action it lowers the rod and
sets the weighing gear free to move.
According to another of my arrangements I dispense with the loose locking rod, as
described in my first arrangement-I substituto in its place a fixed one to the exten led
arin of the weighing gear-It consists of a flat piece of metal, having two projecting
guide pins, one on each edge, and a holo in the centre to receive a hook, and a short
rod projecting from the flat surface upwards has a projecting hook-It is fixed to the
extending arm of the weighing gear in an upright position, passing through the frame
of the machine close to the base of the column. At the base of the column, the
mechanism is fixed to a piece of metal, or framed pieces, and covered by the frame.
The mechanism consists of a Teo shaped beam, with two projecting fulcrum spindles
one on each side in advance of the vertical part-One end of the horizontal part has a
hopper fixed, and the other end a shifting balance weight, with set screw, the vertical
part having a projecting hook-The spindles work on knife edged bearings fixed to the
piece of metal or frame work.
A disc of metal with two slots one at right angles and the other vertical (below the
centre) pinned to the framework about one and a half inches above the Teo shape beam
and in advance about one inch of the projecting spindles.
The aforesaid projecting hook, on the short rod works in the right angle slot of the disc.
A cranked lever is pinned to the Tee shape beam, the crank end of the lever works
into the vertical slot. The other end of the lever comes under the hopper and forms
the bottom, and is connected to the fulcrum pin under the beam by a nut on a square
shoulder, but this end is slotted to allow the lever to be lengthened or shortened for
receiving different sized coin. If extended no coin will fall through, if shortened
small coin will fall through and not operate. The cranked part of the lever is fixed on
the fulcrum pin above the beam.
The action of the lever is reciprocatory on a horizontal plane, and if used above the
Tee shape beam and a platform used in place of a hopper, it will sweep the money off
the platform into a drawer below.
The action of the mechanism will be as follows-When the Tee shape beam is at
rest, the hook on the vertical part will be through the holo of the flat piece of metal
and the machine is locked-on the amount of the Toll being placed in the shoot, which
will conduct it to the hopper, that part of the beam will be weighed down, and at the
same time, the hook on the vertical part will be drawn out of the hole, and the machino

page_text: is unlocked and free to move, and a person standing on the platform will cause the
projecting hook in the right angle slot to lower, and so pull the disc round its fulcrum
pin, the vertical slot at the same time will move the crank lever, and the money will
fall through the hopper, or be swept off the platform as the case might be.
On the person leaving the platform the back action will be from the coil springs, the
pin in the right angle slot forces the disc back, carrying the crank lever with it and
the counter balance weight on the beam, will cause that part of the beam to fall, and
carry the hook on the vertical part through the hole, and the machine will be locked,
and will remain so until the operation be repeated.
According to another of my improvements 1 make a Tee shape beam which has
knife edge (or round) spindles projecting from it on each sido in a straight line of the
vertical part of the lever, and the extreme end of the vertical part works in a slotted
bolt which is kept in its position by a guide piece, and on one end of the horizontal
part is a sliding balance weight with a set screw, and on the other end of the
horizontal part is a hopper, and a crank lever with a Tee shape, slide the lower part
of the hopper is formed to receive a Tec slide piece which has two slots, one slot
horizontal the other vertical, and the cranked lover on one end has a projecting pin,
the other end is slotted.
.
The lever is pinned to the Tee shape beam about one inch in advance of its spindle
bearings, and the action is right angle reciprocating motion.
The slotted end of the lever is on the projecting pin of the upright piece that is
fixed to the extending arm of the aforesaid weighing gear, the pin at the other end
of the lever is in the vertical slot of the slide, the horizontal part of the slide is in its
place under the hopper. The position of the Tee shape beam when at rest is as
follows The bolt at the end of the vertical part will be passed through the hole of the
upright piece, fixed to the extending arm of the aforesaid weighing gear, but as soon
as the amount of toll in money is placed into the hopper that end of the lever will fall
to a stop sufficient for the vertical part to withdraw the bolt from the said hole and
set the weighing gear free to move. The motor that moves the cranked lever is the
weight on the platform which presses down the extending arm of the weighing gear
and carries the upright piece that is fixed with it, moving the projecting pin in the
said slot causes the lever to move round its fulcrum pin, the pin at the other end of
the lever being in the vertical slot of tho Tee slide piece is moved forward under the
hopper, and the money falls through into a drawer below.
The motor of the back action is from the two coiled springs-As soon as the weight
is removed from the platform the pin in the slotted end of the lever moves upwards,
and the lever is forced upwards to its starting point, and the Tee slide is moved back to
its starting point, then the Teo shape beam will by the sliding balance weight cause it to
return to its starting point, and the bolt at its vertical end passes into the hole and
locks the weighing gear and will remain so until the operation is repeated.
According to another of my improvements 1 use a Tee shaped beam with two round
projecting spindles, one on each side and in a line, and over the vertical part of the
beam, and a hole is formed in the vertical part to receive a pin and about half an inch
from the extreme end below the hole it is bevelled from the inner to the outer edge to.
allow the pin to pass' into the hole freely, the aforesaid spindles work on knife edge
bearings fixed to the metal frame.
Ono end of the horizontal part of the Tee shaped beam has a platform with hopper
to receive the money, the said hopper moves on projecting spindles over the platform
(I prefer this to a fixed hopper and moveable bottom) and on the other end of the
horizontal part is a shifting balance weight, and set screw-or a thread cut through.
the balance weight and on the beam, will be equivalent to regulate the amount of Toll
to be paid.
The flat piece of metal as in the other arrangements is fixed to the extending arm of
the compound levers in an upright position, but in this arrangement it has four project.
ing pins, two act as guides, one on the flat surface passes into the hole on the vertical
part of the Tee.shaped beam, the other is below the guide pin and flush with the edge
of the metal, the metal being cut away sufficiently to allow the slotted end of the lever:
J

page_text: to move on this pin freely. A crank lever one end slotted, and a little above the slot
and below the Tee beam and a little in advance of the spindles, is pinned to the frame of
the machine which pin will be its fulcrum. The slotted end of the lever is on the
aforesaid pin on the edge of the metal, the other end is under a projecting side piece on
the hopper and will turn the bottom part outwards. The hopper is weighted on one side
and rests against a stop and is hung above the platform and works and moves on its
projecting spindles. When the Tee shape beam is at rest the projecting pin, that is
on the flat surface of the aforesaid piece of metal, will be through the hole in the vertical
part of the beam and the machine gear, the compound levers, will be locked. A
suitable short piece of conducting tubo is fixed over the hopper in continuation of the
column conducting tube.
The action will be as soon as the amount of Toll in money is placed through the
slot into the hopper that end of the beam will fall to a stop sufficient to raise the
vertical part and to withdraw the hole from the pin and to unlock the weighing gear,
that is the compound levers, and it will then be free to move and as soon as any weight
is placed on the platform the slotted end of the lever on the pin will move and at the
same time the other end under the projecting piece of the hopper will move the hopper
on its spindles sufficiently to sweep the money off the platform into a drawer below.
The lever has a reciprocating motion, the back being from the two coiled springs as
soon as the weight is removed off the platform; the lever will at the same time be
carried back to its starting point and tho hopper will fall to its resting place over the
platform. The horizontal part of the Tee shaped beam by its counter balance weight
will fall and the hole in the vertical part will pass on the pin and so lock the weighing
gear, the compound levers and remain so until the operation is repeated.
According to another of my improvemonts 1 apply the Tee shape beam direct under
the extending arm of the weighing gear and so dispense with the short upright piece,
the fulerum bearings of the beam will be fixed to the machine frame, the beam will
have a platform instead of a hopper, and a shifting counter balance weight and
projecting spindles (as the others) the beam bearing will be fixed under the centre of
the extending arm of the weighing gear--the vertical part of the beam being upwards,
and under the centre of the arm of the weighing gear and against a stop, but will not
quite touch the arm, so that it may be free to move on the money being placed on the
platform, and as soon as the money is on the platform the weight will cause that part
of the beam to fall to a stop, and the point of the vertical part of the beam will at
the same time be removed from under the arm, and the weight on the platform will
cause the arm to move downwards and either one of the arrangements for removing
the money off the platform can be applied to this arrangement, and on a person
leaving the platform the Teo lever will resumo its back action by the counter balance
weight, and so lock the weighing gear.
According to another of my improvements I make the dial to move and dispense
with the traversing finger.
give the required rotary, reciprocating motion to the indicating dial by using the
usual two coiled springs with rack, pinioned spindle, the carrier is a flat piece of metal
with two slots horizontal, one at each end, the centre has a round projecting boss on
one side, the said boss has a round hole through its centre to fit on the spindle, and
the dial has a round hole in its centre to admit the boss to pass through, and the hole
in the boss passes on to the spindle and is kept there by a cotter passing through the
boss and spindle or it may be a nut and screw, this end will rest on an arbor bearing,
the shank end of a flat headed screw is passed through each slot and screwed into the
dial, and so connecting the dial to the spindle, the two slots are for the purpose of
allowing and shifting the dial to zero before it is screwed up tight.
I fix a finger pointer to the frame at the top, close to the indicating dial, the dial
will revolve to this point and show the weight that is on the platform of the
m chine.
I fix suitable guide pieces to the frame, to keep the dial steady, or a groove if
necessary and 1 fix an india rubber or other suitable stop, to stop the dial in its back
sudden movement from passing the point zero, and prevent any jar.

page_text: I cover the face of the dial with glass in a frame hinged with lock and key, or it
may be screwed on; or I cover the dial all over except a space large enough to show
the weight.
The dial may be made of any suitable light metal, wood, vulcanite, india rubber, or
papier machiè, or the like with or without enamel.
The action will be the teeth of the rack will engage the tooth wheel or pinion on
the spindle, and the spindle will turn carrier or driver and so turn the dial.
I make a suitable cast iron frame with all necessary bearings for fixing and carrying,
and cover in all the mechanism applied to the weighing machine. The frame also has
two sides and one end, a few inches above the platform to prevent other persons putting
their feet on the platform when a person is being weighed.
The frame has four wheels, and four screw legs, the object of the screw legs, is to
keep and set the machine level and from moving when in its place, the legs can be
screwed up or down to fit the floor, and to take the weight off the wheels.
The said Tee shape beam with the combined mechanism can be applied to other kinds
of weighing machines having other springs than coiled.
It can also be applied to beam, or any suitably constructed weighing machines with
or without a platform.
The mechanism applies equally to weighing machines that have a fixed indicator,
dial and a traversing finger.
The mechanism with the rotary reciprocating dial, or a fixed dial with traversing
finger, may be applied to any convenient part of a spring dynamometer especially to
test the strength of persons for the same purpose and same object (viz. to lock and
unlock the action of the machine, and to collect the Toll) and the two may be fixed to
the same frame, or fixed separately.
Having explained the nature of my invention I will proceed to describe with
reference to the accompanying drawings, the manner in which the same is to bo
performed.
Figures 1-2 and 3 show my first arrangement as applied to a spring balance
weighing machine.

of the lever a. falls till it rests on the arm of the cam piece c and the other end of
the said lever is clear of the notch in cam piece c then when the person gets on to
the platform the Tee shaped lever and is brought into a horizontal position
which forces up the arm of the cam piece c, throwing up the lever a and letting
fall the locking rod and so releasing the weighing gear and the weight is indicated
on the dial, and on the person stepping off the platform, the mechanism resumes its
normal position.

my second arrangement.
a is a Tee shaped beam with platform k at one end of the horizontal portion and-a
balance weight at the other fixed by a set screws the vertical portion of the beam a

When the amount of Toll is placed on platform that end of the Tec shaped beam
descends until the vertical part is withdrawn from the bar and rests against the
stop d-then-when-the-weight is placed on the weighing platform the bar descends,
the hooked end a pulls round the disc c and the disc c forces round the levor c¹
which sweeps off the coin or coins (or allows it to fall through the hopper as in
Figures 15 and 16) and the weight will be indicated on the dial, on the weight being
taken off the platform the mechanism resumes its normal position. Figure 7 is an
elevation Figure 8 a plan of the Tee shaped beam a, used in Figures 4-5-6 Figure 9

and Figure 18 a side elevation of another of my arrangements the same as the fore-
going except that instead of the vertical part of the beam a being hooked, it works
in a slot in a bolt o passing through the bar and working in guide pieces o¹-o'-o'.
Any of my arrangements for getting the amount of Tool off the platform or hopper k
may be applied to this.
Figure 19 is a front elevation Figure 20 a side elevation and Figure 21 a plan of
another of my arrangements. a is a Tee shaped beam working on spindles g. 9 in a
framo h. 7, with a balance weight bat one end and a hopper at the other. sare
set screws or rivets for fixing hopper k to beam a. is a Tec shaped slide which
passes underneath the hopper & and has a slot to prevent Toll falling through until it
is moved the vertical slot works on a pin c³ of the cranked lever c which is attached
to the beam a by a set screw s and which has a slotted arm working on a pin a³ of
the bar which said bar is attached to the extending arm of the weighing gear as
already described. a² a² are the guide pins of the bar r which work in a slot of the
frame h. . The lower end of the vertical part of the beam a has a hole which passes
easily on to a pin or stud p fixed into the bar 7. d' is a distance piece for the
frame. When the amount of the Toll is placed in the hopper k that end of the
beam a. falls until the beam rests against the stop d. then when the weight is placed
on the weighing platform it causes the bar r to descend and the piu a pulls the
cranked lever c. which pushes forward the slotted Tee slide piece c¹ so releasing the
amount of Toll from the hopper and the weight is indicated on the dial, on the weight
being removed from the weighing platform the mechanism resumes its normal
position.

weighing platform the bar r. descends and the pin a³ pulls round the crank lever c.
and its extreme end comes in contact with the flap piece of the hopper k.causing it
to swing outwards and so release the coin on the weight being removed from the
platform the mechanism resumes its normal position.

the case may be like that in Figure 29.
The four arm fan hereinbefore referred to and the conducting tubo in Figures 27

they will not therefore be useful in any of my arrangements but will apply to other
automatic machines.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that I am
aware of Everitt's specification No. 16433 of 1884 Salter's Specification No. 6983 of
1886 and Pages Specification No. 12576 of 1885 and I do not claim anything therein
