I, GEORGE SALTER of the Firm of George Salter and Company of West
Bromwich in the County of Stafford, Manufacturer, do hereby declare the nature
of this invention to be as follows:-
This invention appertains to that class of weighing machines in which a fee is
charged for ascertaining the weight of a person or other object requiring to be
weighed and the object of my said invention is to dispense with the use of an
attendant at such weighing machines, by making the fee tendered in payment
for weighing, the means of liberating certain check arrangements, which when
removed, allow the weight of a person to be indicated on a graduated dial, by the
movement of a traversing finger, operated by suitable weighing and transmitting
mechanism Thus a person requiring to be weighed, places a penny through a
slit in the side of the machine the weight of which removes certain stop mechanism,
and allows the machine to operate; so that the fee for weighing is taken without
an attendant or money-taker being present.
Weighing machines constructed according to my invention, may be used for
public weighing of every kind, where a fee is charged.
I will describe my invention in connection with an ordinary machine of the kind
herein before indicated.

I. GEORGE SALTER of the firm of George Salter and Company of West
Bromwich in the County of Stafford, Manufacturer do hereby declare the nature
of said invention for "IMPROVEMENTS IN OR ADDITIONS TO WEIGHING MACHINES,"
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention appertains to that class of weighing machines in which a fee is
charged for ascertaining the weight of a person or other object requiring to be
weighed for which a Patent was taken out by Percival Everitt in 1884 No. 16,433 and
described in the Specification thereof and the object of a part of Everitt's invention
viz. that shewn in Figures 1 to 6 is the same as the object of a part of my said invention
is viz. to dispense with the use of an attendant at such weighing machines, by making
the fee tendered in payment for weighing, the means of liberating certain check
arrangements, which when removed, allow the weight of a person to be indicated
on a graduated dial, by the movement of a traversing finger, operated by suitable
weighing and transmitting mechanism. Thus a person requiring to be weighed,
places a penny through a slit in the side of the machine, the weight of which removes
certain stop mechanism and allows the machine to operate; so that the fee for
weighing is taken without an attendant or money taker being present.
Weighing machines constructed according to Everitt's and according to my
invention, may be used for public weighing of every kind where a fee is charged.
I will describe my invention in connection with an ordinary machine of the kind
hereinbefore indicated.
Situated and working vertically within a hollow casing (having an indicator
dial at its front) is a motion transmitting rod, connected at its lower end to a
platform or seat, and at its upper end to a cross head or T piece which is connected
to the lower ends of two coiled springs, depending from lugs situated on the top
of the inside of the casing; and in the middle of the dial and casing is an axis
carrying a toothed wheel or pinion which engages with the teeth of a rack, free at
its top, and connected and jointed at its lower end to the motion transmitting rod
or to the T piece before named-The joint upon which the rack turns is a little
out of the centre, so that a coiled spring pressing on its bottom or underside, keeps
the rack constantly up to its work.
Jointed to the framing near the side of the motion transmitting rod below
the piece, is a long lever, distending and passing outwardly through a gap in the
side of the framing of the machine into a secondary or supplementary casing or
box, through a slit in which money is passed-This supplementary casing or money
box is situated on the side of and in juxta position to the movement casing before
named; and situated at the joint end, and at right angles to the said lever, is a
locking arm, the upper end of which is presented (when not weighing) to a
shoulder or stop snug carried by the motion transmitting rod, while the other end
of the lever which is in the money-box portion of the machine, carries a tilting
plate upon which the coin is deposited This plate is tilted by a hooked ended
lever turning upon a fulcrum near the inner end, the front or hooked portion of
which said lever is presented to a quadrant or curved arm or its equivalent carried
by the motion communicating rod before named; so that the downward motion of
the rod turns the lever and tips the tilting plate.

page_text: When a person requires to be weighed, the fee in the form of a penny is passed
through the slit and deposited on the tipping plate; the weight of the coin thus
deposited, causes the long arm to be lowered, which removes the short arm at its
joint end from in front of the shoulder or stop on the rod. The person then
mounts upon the platform or sits upon a chair as the case may be, when the
motion transmitting rod is pulled down, distending the spring or springs, lowering
the rack which rotates the finger axis, thereby indicating the weight.. The
downward movement of the rod, presses the quadrant arm carried by it upon the
short end of the tipping lever, thereby raising the other or front end, which turns
the tipping plate upon its joint, and removes the penny which is deposited in the
box or receptacle.
On a person leaving the machine, the parts resume their normal positions, while
the lever which blocks the movements, is returned by a spring or counter poise
weight.
I will now proceed to describe with reference to the accompanying Drawings
the manner in which the same is to be performed.
Figure 1 is a side elevation partly in section of an automatic weighing machine
constructed according to my invention, a portion of the body of the machine being
broken off. Figure 2 shows a section of that portion of the machine containing
the weighing and check mechanism, the dial of the machine being partially
removed The said machine figure 2 is also shown out of action or with the
parts in the positions which they respectively assume before the desired or pre-
determined fee or coin is placed upon the tipping plate on the end of a lever
which liberates or takes away the check mechanism, in order to allow an object
resting upon the platform of a machine to be weighed-Figure 3 represents the
check or stop mechanism removed from the bar of the weighing mechanism, by
the gravitating weight of a pre-determined coin or fee, which is shown in the act
of falling into the box or receptacle made to receive it-Figure 4 is a side
elevation of a portion of the frame of the machine, exhibiting the slit-hole through
which a coin passes.
The same letters of reference indicate corresponding parts in the several figures
of the Drawings.
a is a hollow casing wherein the weighing and transmitting mechanism is
enclosed, and b is an indicator dial situated on the front of the said casing-c is a
weight transmitting rod through which motion is communicated from the platform
or seat d, (see figure 1) to the arbor e carrying the indicating finger g-The said
rod or bar c carries a T or cross head c² at its upper end to which the lower ends
of two coiled springs are connected-These springs depend or hang from
lugs on the top of the inside of the casing a-The said arbor or axis e carries a
toothed_pinion which engages with a rack i carried by, and jointed at to the
rod or piece e c²; so that the joint end upon which the rack turns is cranked
which admits of a coiled spring being placed under the heel or bottom of the
underside of the rack, so as to constantly keep it up to its work is the index
bracket and rack guide, and k is a hooked ended rod connected to the lower end of
the transmitting rod c, and through this rod or link k motion is communicated
from the platform d by means common to this class of weighing machine; the
vertical movement of the parts is determined by guides - is a long lever, with
a short cranked arm 12, the outward end of which (when not weighing) is presented
to a shoulder or stop snug m, carried by the motion transmitting rod c, while the
other end of the lever which is in the money box portion a² of the machine,
carries a tilting or tipping plate n, jointed at n³; and upon which plate a coin or
other weighted fee is deposited and passed thereon, through the slit or opening o,
as best seen in figures 1 and 4, and also represented in dotted lines in figure 2-
The lever and cranked arm at its end turns uponthe fulcrum centre p is a
delicate counter-poise spring for returning the lever to its normal position after
the over-balancing of the arm, and the removal of the coin or fee from the tipping
plate, by the turned or crutch end portion q² of the lever q. This lever q is jointed

page_text: at q thus forming a long and short arm, the latter of which is presented to a
curved projection or plater carried by the motion communicating rod c; so that
the downward motion of the said rod through the influence of the curved plate r
turns the lever upon its fulcrum centre, and inclines the plate to a sufficient
angle so as to compel the coin s to slip from off it, and be deposited in the box a²;
access to which is gained by the hinged door a³.
The levers and pass from the weighting mechanism casing, to the supple-
mentary casing or money box a², by a slit or opening a*.
When a person or object requires, or is required to be weighed, the fee in the
form of a penny is passed through the slit or opening o, and deposited on the
jointed tipping plate n, the gravitating weight of the coin thus deposited, causes
the long arm or lever to be lowered into the position as represented in Figure 3,
and which said lowering of the lever removes the cranked short arm 2 from in
front of, or from under the check stop n, thereby liberating or setting free the
weighing and indicating mechanism; the person or object to be weighed then
mounts or is placed upon the platform, when the weight of the person or other
object, pulls down the motion communicating bar c, distends the springs ff, lowers
the rack which rotates the finger axis or arbor e through the pinion hand so
indicates the weight of the person or other object by the finger g traversing and
coming in front of the graduations of the dial.
The downward movement of the said bar e causes the curved plate or shoulder
to turn the lever upon its centre q³ so as to bring the hooked or crutch end q² in
contact with the plate n, and tip it or incline it upwards, so that the coin s shall
be slipped from off or be removed therefrom, into the receptacle a²-Thus the
levers and g are so arranged that the machine is rendered automatic by the
gravitation of a pre-determined coin (or weighted fee) placed upon the end of
the lever g, so as to lower the said lever and also turn it upon its joint centre, to
an extent that will remove the impediment in the form of the arm
12 from
shoulder stop or its mechanical equivalent carried by a movable part of the
weighing portion of the mechanism.
It therefore follows from the description herein given that a person cannot be-
can only be weighed unless by my invention if the requisite coin be passed through the
slit hole made for the purpose, and the coin deposited upon the plate which becomes
lowered through the influence of its weight, thereby taking out of position a stop,
which admits of the weighing mechanism being operated, and should a coin of less
weight be tendered in payment for the weighing, then the machine will remain
inoperative until the proper amount is forthcoming; and further, it will also be
understood that the lowering of the lever is only sufficient to take the short arm (2
from out of the way of the stop m of the bar c, and that the coin shall remain upon
the plate even in its lowered position, until the lever or knocker off q shall remove it
from the plate upon which it rests; for if this was not so, a person requiring to be
weighed might place the coin through the slit, which would operate the releasing
mechanism and return the parts to their normal positions before a person would
have time to get upon the platform. This is obviated by the lower lever 9. which
can only be operated by the lowering of the curved plate or shoulder which is
effected by the pulling down of the bar c, on a person or a weight being placed
upon the platform.
On a person or object being removed from the platform of the machine, the
parts resume their normal positions as represented in Figure 2.
Although I have described and represented that the lever is brought back by
a counterpoise spring p, yet it may if necessary be returned to its normal position
by a counterpoise weight suspended from one end of a cord passing over a pulley,
and with the other end connected to the lever. The counterpoise is of such
a weight that the coin deposited on the end of a lever is sufficient to raise
the weight, and the weight to again raise the lever and plate, on the coin being
removed.

page_text: Instead of the arm being made in the form as described, so as to come under
a shoulder m, the said end may be hooked and made to take into a hole or recess
formed in the edge or side of the bar c or parts carried by it.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that I make
no claim to a machine such as is described and claimed in Everitt's specification aforesaid
but what I claim is-
In an automatic weighing machine, in which an auxiliary device is arranged by
which means it is only allowed to-weigh, or to act, or to indicate the weight of an
object, on a prescribed or predetermined coin or fee having been tendered in
payment for weighing; that is to say, in a weighing machine consisting of ordinary,
or other weighing mechanism, with the addition thereto of supplementary stop
liberating and fixing mechanism or parts, consisting of a balanced counterpoised
lever jointed or pivoted at its inner end, and provided at that end, with a
supplementary cranked short arm 1, which is presented to, and removed (on the
lever-l-making its two positions) which (on the lever 1, taking one or other of its
positions) is presented to or removed from (as the case may be) a shoulder or stop m or
its equivalent, made or formed on, or in, or connected with the weighing transmitting
or transferring rod or part or parts; while the other end of the lever carries a
self-righting tilting plate n, whereon a coin is placed, and by its gravitating weight,
removes the said short arm 12 from its blocking position; and which said plate is
tilted, and the coin removed therefrom, and dropped into a separate receptacle, by a
secondary jointed lever g, operated or controlled by a projection or plate or its
equivalent, carried by, or working in unison with the motion transmitting bar or bars
of the machine. The said supplementary parts as set forth are constructed, arranged
and work in the manner, and in conjunction with the other or weighing parts of the
machine, for the purpose substantially as described and illustrated.

Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is―
$
In an automatic weighing machine, in which an auxiliary device is arranged by
which means it is only allowed to weigh, or to act, or to indicate the weight of an
object, on a prescribed. or predetermined coin or fee having been tendered in
payment for weighing; that is to say, a weighing machine consisting of ordinary,
or other weighing mechanism, with the addition thereto of supplementary stop
liberating and fixing mechanism or parts, consisting of a balanced counterpoised
lever jointed or pivoted at its inner end, and provided at that end, with a
supplementary cranked short arm l, which is presented to; and removed (on the
lever making its two positions) a shoulder, or stop m or its equivalent, made or
formed on, or in, or connected with the weighing transmitting or transferring rod
or part or parts; while the other end of the lever carries a self-righting tilting
plate n, whereon a coin is placed, and by its gravitating weight, removes the said
short arm from its blocking position; and which said plate is tilted, and the
coin removed therefrom, and dropped into a separate receptacle, by a secondary
jointed. lever q, operated or controlled by a projection or plate or its equivalent,
carried by, or working in unison with the motion transmitting bar or bars of the
machine. The said supplementary parts as set forth are constructed, arranged and
work in the manner, and in conjunction with the other or weighing parts of the
machine, for the purpose substantially as described and illustrated.
Dated this tenth day of June 1886.
