"IMPROVEMENTS IN MACHINES FOR CHECKING MONEY TAKINGS, AND REGISTERING
THE AMOUNT."
This Invention of improvements in machines for checking money takings, and
registering the amount, consists in applying the variable diameters of coins of
copper, silver, or gold as a means of acting upon certain levers to actuate the
mechanism used as the indicating register.
I apply the principle above described by making a shoot, or hopper, or expanding
mouth-piece either vertical or inclined, in which the sides are movable levers, and
against which the coin presses in its passage to the drawer or receptacle for the
money. The action of the lever or levers is communicated to a reciprocating
bar, which may be kept in place by suitable springs, or other means, so that the
varying width of the coin shall tell its value upon the registering apparatus, which
may be of the usual construction, or with such modifications as may be required to
adapt it to the principle of the variable mouth-piece.
The reciprocating or sliding bar puts in motion a moving incline formed of
suitable curves, by which the variable diameters of the coins adjust their ratios of
value to the registering apparatus.
The apparatus may be made to retain the last coin taken for reference till the
succeeding coin displaces it, as it is now the case in many money-checking ap-
paratus; or if the registering apparatus is constructed to be visible it will itself
indicate the value of the last coin taken.
The Invention also consists in adapting to the registering apparatus such elec-
trical connections that by means of wires taken to any required locality a duplicate

page_text: registering machine may be put in action, and also indicate, for instance, in the
office of the proprietor of the receiving instrument the amount taken from time to
time, or in some cases the reciprocating bar is made to register the length of its
stroke in the office of the proprietor. One means of doing this consists in spacing
off the bar with points of contact, so that for each length of stroke of the bar a
certain defined number of pulsations are transmitted to the receiving instrument
in the office by the action induced upon any kind of armature acting on ratchets
or palls in the ordinary well-known manner of such instruments, the action being
employed also in printing off the results when desired.
The machine may be constructed for either copper, silver, or gold, or for all three,
but in such cases I prefer a separate mouth-piece for each kind of metal.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Henry Edwin Sambrook in the Great Seal Patent Office on the
11th July 1877.

"IMPROVEMENTS IN MACHINES FOR CHECKING MONEY TAKINGS, AND REGISTERING
THE AMOUNT."
The Invention consists in applying the variable diameters of coins of copper,
silver, gold, or other metal, as a variable means of acting upon certain levers to
actuate the mechanism used as the indicating register.
I apply the principle above described by making a shoot, or hopper, or expanding
mouth-piece either vertically or inclined, in which one side or both sides are moveable
levers, and against which the coin presses in its passage to the drawer or receptacle
for the money.
The action of the lever or levers is communicated to a reciprocating bar, or
levers and connections, so that the varying width of the coin shall tell its value
upon the registering apparatus, which may be of the usual construction, or with
such modifications as may be required to adapt it to the principle of the variable
mouth-piece.
The reciprocating sliding bar or cam puts in motion a moving incline or cam
formed of suitable curves, by which the variable diameters of the coins adjust their
ratios of value to the registering apparatus.
The lowest denomination, or coin of lowest value, is made the intiger, so that
the register becomes the multiple of this denominator. The train of wheelwork is
therefore so divided that a coin of the lowest value shall be represented by, say,
one tooth, and a coin of twice, thrice, or more value by two, three, or more
teeth, the dial progressively showing the sum total of the money placed in the
machine.
Obviously the machines are independent for gold, silver, or copper, and any set
of coins are applicable for registration. No claim is made for any Invention as to
the counters or index registers of the total amount, as the way in which these may
be constructed are well known, and have been previously constructed in many
varieties of form, whether by trains of wheelwork and dials or by electrical impulses ;
the latter may even be used to show the register in duplicate in some distant office
when required.
Besides the total register the apparatus is constructed to indicate the coin put
into the receptacle, the indicator showing the last coin placed therein until a suc-
ceeding one readjusts the indicating hand.
In the Drawings Figure 1 represents a view from the back of the moveable parts
of one of the machines, the back plate of the machine supporting the axles of the
moving parts being removed.
a is the front plate of the machine; b, the aperture into which the coins are

page_text: introduced; c, the one fixed side of the variable mouth-piece; d, the axle carrying
the moveable side of the mouth-piece or shoot; d¹, the moveable side between which
and c the coin is forced down by the iron finger e turning on the centre e¹, and
actuated by the knob or handle shown in Figure 2. The coin being dropped into
b the handle is rotated, and the coin forced down by the finger e; as it passes down
it moves the side d¹, and acting through the cam and slot e³ moves the lever f,
turning on the pin f¹ by the pin f2, and by the rack f³ puts in motion the pinion g..
On the axle g is fixed the ratchet wheel on which acts the pawl g¹. It will be
obvious that, as before stated, if a certain denominator represents one tooth of a
pinion keyed on the axle of g, which one tooth is propelled by the displacement
caused by the diameter of the denominator acting on the piece d¹, all that is
required is so to adjust the cain slot at e³, that whatever the denomination of coin
is placed in the machine it shall register its multiple of the denominator, be it two,
three, or more times the value, on the train of wheelwork proceeding from the axle
of the pinion g, and that the register will thus be accumulative, or register the total
amount of money taken, the register dials being composed in any suitable and
convenient manner.
To ensure a complete stroke of the finger the finger has constructed on it, or
attached to it, a rack f* and a pawl ƒ³. Once started the pawl prevents a return
of the finger until it has completed the stroke, and allowed the pawl f³ to enter
the recess f; the finger may then be turned back, but in like manner it must com-
plete the full return stroke till the pawl enters the recess f".
i
Attached to the cam plate e³ is a connecting rod h, which by the slotted end h¹
raises the pin on the wheel i2; this wheel carries the index pointer 3, and will,
as is evident from the Drawing, indicate by being lifted up to certain positions,
according to the different diameters of the coins, their different values. At each
such position of the pointer is therefore placed a coin or figure of the required value,
and as this part of the apparatus faces the payee it is at once evident to him
whether or not the coin of the value he has paid has been placed in the machine.
A spring j, acting on the wheel 22, retains the pointer in the desired position to
show the last coin taken. When the handle operates the finger to introduce the
next coin the wheel is relieved from the pressure of the spring, and the pointer
takes up the position due to the incoming coin.
This mechanism is as follows:-Figure 2, on the finger plate e is attached a small
toggle k, which, on motion being given to the finger e, acts on the projection k¹,
depresses the spring j, and raising the stop k² away from the plate a of the machine
lets the coin fall by the dotted bath into the receptacle or till.
Figure 3 represents a form of the variable mouth-piece in which both sides are
moveable, the sides a and b working on the pivots a, b, the coin being pressed
down by the lever c, upon which slides the button & working in the slot e. When the
handle c¹ of the lever c is depressed the coin passing between the sides a and b
diverges them to the right and left; a small spring f restores the handle to its
upward position, as shewn in the Drawing. The side a has only a small divergence
about half the diameter of the smallest coin; the other 6 actuates the rack g by the
pin gland pinion h, which is in this case the means of actuating the desired register,
as before described, in any convenient manner.
A rack and pawl is fitted to the handle in a similar manner to that described in
Figure 1, and for the same object, to ensure a full stroke of the handle before it can
be lifted up again to the position shown in the Drawing.
It will be understood that the back and front plate of shoot, down which the
money is thrust, are at a distance apart just sufficient to take the thickest denomi⚫
nation of coin, and that the moveable levers slide between these plates accurately,
so as to prevent any passage of the coin, except by the edges of side plates. It
is preferable to have these edges slightly concave.
Having now described and particularly set forth the nature of the said Invention,
and the means of carrying the same into effect, I would have it understood that

page_text: what I claim, and desire to secure in the herein in part recited Letters Patent
is,-
-
Firstly. The use of the fixed and moveable sides of the variable mouth-piece,
as shewn in Figure 1, substantially as described.
Secondly. The use of the two moveable sides of the variable mouth-piece, as
shewn in Figure 3, substantially as described.
Thirdly. The combination of the moveable side of the variable mouth-piece with
the cam, or other equivalent, by means of which the varying diameters of the
coins are made to actuate the index and register mechanism, substantially as
described.
Fourthly. The combination of the moveable sides of the variable mouth-piece
with rack and pinion, or other equivalent, by which the varying diameters of
the coins are made to actuate the index and register mechanism, substantially as
described.
In witness whereof, I, the said Henry Edwin Sambrook, have hereunto set
my hand and seal, this Tenth day of July, in the year of our Lord One
thousand eight hundred and seventy-seven.
