Improvements in Automatically Balancing Weighing Machines.
I, CARL SCHENCK, balance-manufacturer, residing at Darmstadt, Grand-duchy of
Hesse, German Empire, do hereby declare the nature of this invention to be as
follows:-
My invention relates to automatic balances, and its object is to produce the auto-
matic action of the balance and the indication of the weight of the load by means of a
weight arranged to travel on the weighing beam, to be shifted thereon lengthwise by
a propelling-mechanism, and to be stopped as soon as it has arrived at a point at
which it poises or tilts the beam. Moreover the invention has in view the combination,
with the beam, of two or more travelling-weights of different size and propelling-
mechanisms that shift the said weights in succession in the order of their size
(beginning with the largest one) and in alternate directions, each weight being moved
a certain distance beyond the point at which it tilts the beam, and each weight after
the first one, deducting the excess brought to bear on the beam by the preceding
weight.
Supposing the balance to be provided with four weights adapted to determine the
thousands, hundreds, tens and units of the number of pounds or other units of weight
contained in the load, and the balance to be charged with a load weighing between
one thousand and ten-thousand pounds, and the automatic weighing apparatus to be
in operation, first of all the travelling-weight for the thousands of pounds is shifted on
the beam away from the load side, say to the right, until, after tilting the beam, it
comes to a point at which its action on the balance is equal to the full number of.
thousands of pounds being next above the true weight of the load, whereupon it is
stopped. Thereafter the travelling-weight for the hundreds of pounds is shifted in
the opposite direction, or to the left, until, after having tilted the beam the other way,
it arrives at the point at which it acts on the balance with a force equal to the full
number of hundreds of pounds being next above the surplus brought to bear on the
right-hand end of the beam by the first weight, the difference in hundreds of pounds
being thus practically deducted. Subsequently the third travelling-weight moves in

page_text: the right-hand direction up to the point at which it balances the full tens of pounds
next above the true number, and finally the fourth weight is shifted to the left for
deducting the surplus of units.
The movement of the travelling weight, or of each weight, in case there are two or
more, is produced by a propelling-mechanism actuated by a vertically-movable driving-
weight, and the travelling-weight is stopped, together with the said mechanism, by
means of a pall that engages with one of a series of notches, provided for upon the
surface of any suitable part of the propelling-mechanism, or part connected therewith,
the said pall or its equivalent being caused or allowed to operate by the motion of the
weighing-beam when the same is poised or tilted through the medium of the travelling-
weight. If two or more travelling-weights are employed, the balance is, moreover,
provided with contrivances whereby each mechanism except the first one is maintained
at rest while the preceding one operates, and is released as soon as the latter is
stopped. Besides, the said mechanisms are provided with means for regulating the
speed of their motion. The weight of the load determined by the travelling-weight or
weights is indicated by the propelling-mechanism or mechanisms, or by a part or parts
connected thereto, for instance by a rotating disk or a series of such disks having
nunerals on their periphery. With these disks a printing-apparatus may be combined
for registering the results of the weighing-operations. The aforesaid driving-weights
are simultaneously raised and the printing-apparatus is worked through the medium
of mechanism brought into action either by hand, or by an auxiliary weight, which is
lifted by the pressure of the load on the balance and liberated when the load is
removed.
The propelling-mechanisms, the stopping devices, the releasing contrivances and
the means of regulation may be as follows.
The driving-weight, or each weight of a series, forms or is secured to a vertical bar
(weight-bar) having rack-teeth that gear with a pinion fixed to an axle which carries
another pinion meshing with teeth on the underside of the corresponding travelling-
weight. The said weight-bar is provided with notches and by its side is arranged a
pall adapted to engage therewith. This pall is operated upon by an arm of the beam,
the pall and the arm being so arranged that, previous to the tilting of the beam by the
travelling-weight, the pall will be free from the notches, whereas when the beam is tilted
or poised by the said weight, the pall will engage with the first notch coming opposite
to it and thus stop both, the mechanism and the travelling weight. If the apparatus
contains two or more travelling-weights and propelling-mechanisms, and if the weight
of the load is to be expressed in the decimal system, the weight-bars are provided with
ten notches each.
A modification of the stopping-device consists in a notched disk fixed to the axle of
the aforesaid pinions connecting together the travelling-weight and the bar of the
driving-weight, and a pall arranged to drop into the notches of the disk, the said pall
being supported and kept free from the disk by a tongue of the weighing-beam until
the latter is tilted by the travelling-weight. Previous to the weighing-operation the
pall is disengaged from the disk by means of a pin on the weight-bar, so that the
tongue of the beam may slip under the pall when the beam is tilted by the pressure of
the load.
The regulation of the motion of the propelling-mechanism is preferably brought
about by a simple pendulum clock-work, the driving-wheel whereof gears with the
rack-teeth of the weight-bar.
In case two or more travelling-weights and propelling-mechanisms operating in
succession are combined together and with pendulum regulators, a connection is
established between the first and second propelling-mechanisms by means of a double-
armed lever, one arm thereof extending across the weight-bar of the first mechanism,
which is provided with a'pin or shoulder for raising the lever when the bar, on being
raised, is near the top of its course, whereas the second arm extends into the path of
the pendulum of the second mechanism and has at its end a projection adapted to
catch the pendulum when the latter is swung outward and the said arm is raised
through the medium of the first arm. Besides, the beam of the balance is provided

page_text: below the first one of the said arms with a vertical tongue, alike to the one mentioned
relatively to the modified stopping-device, and adapted to support the arm close to a
transverse edge formed thereon, the tongue and the said edge being, however, so.
arranged relatively to each other that, when the beam is tilted by the overbalancing
action of the first travelling-weight, the tongue slips away from under the arm, in
consequence whereof both arms drop down and the second arm releases the pendulum
of the second mechanism, which thereupon commences to operate. A like connection
is established between the second and third mechanisms, &c. In order that, previous
to a weighing-operation, all the pendulums be swung into a position from which, on
being released, they will commence to oscillate, and that the second and following
pendulums be engaged by the corresponding lever-arms, the pendulums have lateral
arms which are acted upon from below, simultaneously with the raising of the
driving-weights, through the medium of a lifting-bar. The levers being at the same
time raised by the pins on the weight-bars, the second and following pendulums will
be caught. As soon as the said lifting-bar is thereupon lowered, the first pendulum
is free to oscillate and the apparatus commences to work.
If, in the compound apparatus the modified arrangement of the stopping-device,
comprising a notched disk, is employed, the pall engaging with the notches of the
said disk, is formed by the first arm of the aforesaid double-armed lever, which is for
this purpose provided with a suitable beak.
The aforesaid disks having numerals for indicating the weight of the load, are fixed
to the axles of the pinions connecting together the travelling-weights and the driving-
weights, the outer ones of the said axles being made tubular and passed one over the
other and over the inner solid axle, so as to allow of the disks being placed side by
side.
If the indications of the numeral-disks are to be registered, the numerals are made
projecting, a printing-lever is arranged opposite to them, and a strip of paper is
drawn forward between the numerals and the lever by rollers and a ratchet-
mechanism, the latter and the lever being operated by a bar connected with the
device for raising the driving-weights.

Improvements in Automatically Balancing Weighing Machines.
I, CARL SCHENCK, balance-manufacturer, residing at Darmstadt, Grand-duchy of
Hesse, German Empire, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :—
My invention relates to automatic balances, and its object is to produce the auto-
matic action of the balance and the indication of the weight of the load by means of a
weight arranged to travel on the weighing-beam, to be shifted thereon lengthwise by
a propelling-mechanism, and to be stopped as soon as it has arrived at a point at which
it poises or tilts the beam. Moreover, the invention has in view the combination, with
the beam, of two or more travelling-weights of different size and propelling-mechanisms
that shift the said weights in succession in the order of their size (beginning with the
largest one) and in alternate directions, each weight being moved a certain distance
beyond the point at which it tilts the beam, and each weight after the first one
deducting the excess brought to bear on the beam by the preceding weight.
Supposing the balance to be provided with four weights adapted to determine the
thousands, hundreds, tens and units of the number of pounds or other units of weight
contained in the load, and the balance to be charged with a load weighing between
one thousand and ten-thousand pounds, and the automatic weighing apparatus to be
in operation, first of all the travelling-weight for the thousands of pounds is shifted on
the beam away from the load side, say to the right, until, after tilting the bean, it
comes to a point at which its action on the balance is equal to the full number of
thousands of pounds being next above the true weight. of the load, whereupon it is
stopped. Thereafter the travelling-weight for the hundreds of pounds is shifted in
the opposite direction, or to the left, until, after having tilted the beam the other way,
it arrives at the point at which it acts on the balance with a force equal to the full
number of hundreds of pounds being next above the surplus brought to bear on the
right-hand end of the beam by the first weight, the difference in hundreds of pounds
being thus practically deducted. Subsequently the third travelling-weight moves in
the right-hand direction up to the point at which it balances the full tens of pounds
next above the true number, and finally the fourth weight is shifted to the left for
deducting the surplus of units.
The movement of the travelling weight, or of each weight, in case there are two or
more, is produced by a propelling-mechanism actuated by a vertically-movable
driving-weight, and the travelling-weight is stopped, together with the said mechanism,
by means of a pall that engages with one of a series of notches, provided for upon the
surface of any suitable part of the propelling-mechanism, or part connected therewith,
the said pall or its equivalent being caused or allowed to operate by the motion of the
weighing-beam when the same is poised or tilted through the medium of the
travelling-weight. If two or more travelling-weights are employed, the balance is,
moreover, provided with contrivances whereby each mechanism except the first one is

page_text: maintained at rest while the preceding one operates, and is released as soon as the
latter is stopped. Besides, the said mechanisms are provided with means for regu-
lating the speed of their motion. The weight of the load determined by the travelling-
weight or weights is indicated by the propelling-mechanism or mechanisms, or by a
part or parts connected thereto, for instance by a rotating disk, or a series of such
disks, having numerals on their periphery. With these disks a printing-apparatus
may be combined for registering the results of the weighing-operations. The afore-
said driving-weights are simultaneously raised and the printing-apparatus is worked
through the medium of mechanism brought into action either by hand, or by an
auxiliary weight, which is lifted by the pressure of the load on the balance and
liberated when the load is removed.
Fig. 1 of the annexed drawings is a diagram of a weighing-beam with a single
travelling-weight and apparatus for automatically actuating the same. Fig. 2 is a
modification thereof. Fig. 3 is a sectional view of the complete balance, in which,
however, some of the details are omitted. Fig. 4 is a view of a portion thereof with
some of the parts in different position. Fig. 5 is a sectional elevation of a weighing
beam carrying three travelling-weights and of the mechanism for automatically
actuating the weights, a portion of the right-hand end of the beam being broken off.
Fig. 6 is a transverse sectional view and Fig. 7 a plan corresponding to Fig. 5.
Fig. 8 shows the automatic registering device in elevation, the frame of the apparatus
being omitted in order to allow all parts to be represented in full lines. Fig. 9 is a
diagram corresponding to a section on line 1, 1 of Figs. 6 and 7 and showing the
weighing-beam depressed at its left-hand end, and the first mechanism for automatic
action released and about to commence working. Fig. 10 is a like diagram repre-
senting the same mechanism at the end of its operation and the beam tilted the other
way. Fig. 11 is a sectional diagram corresponding to the line 2, 2, Figs. 6 and 7,
and in which the second mechanism is released and on the point of starting, the beam
being in the same position as in Fig. 10. Fig. 12 shows the second mechanism at
the end of its operation, the beam being again tilted down at its left-hand end.
Figs. 13 and 14, corresponding to line 3, 3, Figs. 6 and 7, represent the third
mechanism at the beginning and the end of its action respectively.
In Fig. 1, b is the weighing-beam and a the rod through which the load W, to be
weighed, acts upon the beam. is the travelling-weight running on, and guided by
the rollers f. c is the driving-weight, which is fixed to the vertical bar i (or weight-
bar) movable in fixed guides. The said weight-bar is provided with teeth by means
of which it gears with a pinion, j, fixed to an axle k that carries another pinion
-meshing with teeth on the underside of the travelling-weight g. (In the figure the
pinions and coincide with each other, and therefore with regard to these pinions
Figs. 6 and 7 are referred to.) The weight-bar has on its surface being opposite to
the aforesaid teeth, notches, and by its side is arranged a pall, e, adapted to engage
therewith. When the beam is depressed at its left-hand end by the load W, an
upright arm m of the beam bears from below against an arm of the pall and keeps the
pall out of engagement with the notches of the bar i; but as soon as the beam is
tilted down at its right-hand end by the action of the travelling-weight g, the arm m
is withdrawn from the pall, so that the pall then engages with the notch which is
opposite to it, the propelling-mechanism and the travelling-weight being thereby
stopped.
In the modified arrangement shown by Fig. 2, the stopping-device consists in the
notched disk y fixed to the axle k, a pall 2 arranged to drop with its beak e² into the
notches of the disk, and tongue t² fixed to the beam band so arranged that, when the
beam is in equilibrium, i.e. in horizontal portion, the tip of the tongue will be below a
transverse edge to formed upon a small branch of the pall h², or upon the pall itself,
whereas when the beam is depressed at the left-hand end by the load, the said tip is
under the body of the pall or of its branch. The pall will thus be supported and kept
free from the disk y by the tongue 2 until the beam is poised or tilted by the
travelling-weight. Previous to the weighing-operation the weight-bar, on being
raised for renewed action, disengages, by means of a pin o, the pall from the disk y

page_text: and raises it sufficiently as that the tongue may slip under the pall or its branch when
the beam is tilted by the pressure of the load.
It will readily be perceived that the tongue 2 is an equivalent of the aforesaid
arm m, inasmuch as both operate to release the pall which, by its engagement with a
notched surface in connection with the propelling-mechanism, serves to stop the said
mechanism and the travelling-weight.
The described balances are shown in the figures unprovided with means for regu-
lating the motion of the propelling-mechanism, although for a proper working of the
apparatus such means are of considerable advantage. Preferably the said regulation
is brought about by a simple pendulum clock-work, the driving-wheel whereof gears
with the rack teeth of the weight-bar, as will be described hereafter.
In figures 5 to 14, representing the balance with three travelling-weights, g g¹g²
are the said weights, c c¹ c² the respective driving-weights, i¹ the weight-bars
having rack-teeth on one side, jjj² 11 the pinions, and kk k² the axles connecting
together the travelling-weights and weight-bars, the axles k and k¹ being tubular and
passed one over the other and over the solid axle k². These axles also carry the
numeral-disks. The two propelling-mechanisms that operate the first and
second travelling-weights g and gl, are alike to the one described with reference to
Fig. 1, except that the palls e and e¹ are so balanced as to be normally free from the
notches of the bars i and it, and that the arms m and m¹ are arranged to press the
palls against the bars i and i¹ when the beam is tilted by the action of the respective
travelling-weight g or g¹, the said arms m and m¹ being made sufficiently resilient as
not to hinder the oscillation of the beam when they press the palls against a portion
of either weight-bar being between two notches. As regards the arm m³, this
resiliency is also required when the arm presses the pall against the bar at the
first oscillation of the beam, produced by the load, which oscillation is not to have
effect on the second mechanism. Provided that the weight of the load is to be
expressed in the decimal system, the number of the notches in each of the said weight-
bars is ten.
11
The third propelling-mechanism, actuating the travelling-weight 92 and comprising
the parts c² 12 and 2, is alike to the one represented by Fig. 2, inasmuch as its
stoppage is brought about by means of the disk y and the pall 2, the said disk having,
however, also ten notches, the same as the bars i and i¹.
With the rack teeth of the weight-bars i 2 gear the respective toothed
wheels n n¹ n², being the driving-wheels of the regulating clock-works having the
pendulums pp p².
Between the first and second propelling-mechanisms a connection is established by
means of a double-armed lever hhx, Figs. 5, 6, 7 and 10, the arm h whereof extends
across the weight-bar i of the first mechanism, the said bar being provided with a
pin o for raising the lever when the bar is in its uppermost position. The second
arm, hx, extends into the path of the bar of the pendulum p² belonging to the second
mechanism and has at its end a projection adapted to catch the pendulum when the
latter is swung outward and the arm * is raised through the medium of the arm h.
Besides, the beam 6 is provided below the arm h with a tongue t, alike to the
tongue 2, mentioned relatively to the modified stopping-device, and adapted to
support the arm h close to a transverse edge t³ formed thereon, or on a branch of the
arm, the tongue and the edge 3 being so arranged relatively to each other that, when
the beam is tilted by the overbalancing action of the first travelling-weight, the tongue
oscillating to the right and slipping past the edge t³, allows the lever hhx to drop, in
consequence whereof the arm h* releases the pendulum p¹ of the second mechanism,
which thereupon commences to work. Between the second and third mechanisms a
like connection is established by means of a lever having the two arms h¹ and h¹×,
Figs. 7 and 12, while the beam is provided, below the transverse edge t* of the arm h³,
with the tongue t¹, cooperating with the arm in analogous manner as the tongue t
cooperates with the arm h, except that it is an oscillation of the tongue t¹ to the left
which causes it to slip past the edge and allows the lever h¹ h¹× to drop.
The aforesaid levers h h*, h h¹× and the pall h² are mounted on a bar o¹, so that

page_text: their centres are all in a line, but for sake of greater clearness these centres are
shown in Figs. 11 and 13 as being by the side of each other. For the same
reason the tongue has in Figures 13 and 14 been drawn sideward of the vertical
center-line of the beam.
In order that, previous to any weighing operation, all the pendulums be swung
into a position from which, on being released, they will commence to oscillate, and
that the second and third pendulums p¹ and p² be engaged by the corresponding
lever-arms hand ¹×, the pendulum-bars have lateral arms p³ that are acted upon
from below simultaneously with the raising of the driving-weights, through the
medium of a lifting-bar pt. The levers h * and h¹ h¹× being at the same time
raised by the pinso on the weight bars, the pendulums p¹ and p² will be caught.
As soon as the lifting-bar p is thereupon lowered, the first pendulum commences to
oscillate, the apparatus being thereby set at work.
The means for raising the driving-weights and the lifting-bar p¹ consist in a
plate q, to which is fixed a rack q¹, Figs. 3 and 4, gearing with a spur-wheel q²
connected by a pinion to a crank 93: When this crank is rotated one way, the
plate 9, acting from below against the weight-bars i 12, Figs. 5 and 6 and the
lifting-bar p, lifts these parts and the weights c c c², while at the same time
the travelling-weights g g₁ g² are brought to their initial positions by means of their
connections with the weight-bars. The crank 73 being thereupon turned the other
way, the plate q is lowered, so that the apparatus is then free to operate.
The mechanism shown in Figs. 3 and 4 in combination with the wheel q² serves to
link together and detach from each other the two rods a and a¹ connecting the weighing-
beam and the lever d of the system of levers carrying the platform z, the rod a¹ being
hooked to the rod a by means of the crank 9 and the hook 95 when the wheel q² is
rotated to lower the plate 9, whereas the rods are disconnected when the wheel is
rotated the other way. This construction does not, however, form any part of the
present invention.
The balance is equilibrated, when the weighing-platform is unloaded and the travel-
ling-weights are in their initial positions, by means of weights placed on the scale b
Figs. 3 and 4.
Supposing that the platform of the balance has been charged with a load weighing,
for instance, 547 lbs., and that the plate q has been raised and lowered again, the
beam 6, the first propelling-mechanism and the parts in connection therewith will be
in the position shown in Fig. 9. The left-hand end of the beam is depressed, the
lever-arm is raised by the pin o, so as to be free from the tongue t and the lifting-
bar p is lowered, so that the pendulum p is at liberty to oscillate. The weight-bar i
will consequently descend and propel the travelling-weight g to the right. At the
commencement of the descent of the bar i, the lever-arm / becoming free from the
pin o, drops upon the tip of the tongue t and is supported thereby so that it keeps
the arm *, Fig. 10, in engagement with the pendulum p¹. When the weight g,
during its motion to the right, passes the point in which it balances the load of 547 lbs.,
it tilts the beam into the position shown by Fig. 10, the resilient arm m con-
sequently pressing the pall e with its beak against the portion of the side of the bar i
being between the fifth and the sixth notch, which portion is at this moment opposite
to the said beak, and, when the sixth notch, corresponding to 600 lbs., has come in
register with the beak, the latter drops into the notch, thereby stopping the first pro-
pelling-mechanism. Actually a surplus amounting, to 600 lbs. minus 547 lbs.,
or 53 lbs., has thus being brought to bear on the right-hand side of the beam, but
the numeral-disk r, Figs. 6 and 7, of the said mechanism, adjusted to indicate at the
time 500 lbs. as the true number of hundreds of pounds contained in the load.
Upon the beam being tilted as stated, the tip of the tongue t slips past the edge t³
of the arm A, in consequence whereof the said arm drops on the fixed pin o', and the
arm h* releases the pendulum p¹, shown in Fig. 10 in dotted lines and in Fig. 11 in
full lines. This pendulum, impelled by the bar and the weight c¹ fixed thereto,
(the weights c c¹² are not shown in Figs. 9-14) then commences to oscillate while
the weight g¹ is moved to the left, and the arm ', liberated by the pin o on the bar i¹,
с

page_text: drops on the tongue t¹. The bar ¹ continues to descend and to move the weight gl
until the latter tilts the beam down at the left-hand end, as in Fig. 12, which it will
do as soon as it overbalances the above surplus of 53 lbs. The resilient arm m¹ then
presses the pall e¹ against the bar and causes it to engage with the sixth notch
thereof when the same has come opposite to it, the second mechanism and the weight g¹
being thereby stopped in the position in which the latter counterbalances 60 lbs., i.e.
7 lbs. more than the actual surplus, the numeral-disk, however, indicating 50 lbs.
These 7 lbs. are again deducted from the said 60 lbs. by the third mechanism and
the travelling-weight g², the said mechanism being set free by the tongue t¹ slipping past
the edge t¹ of the arm h¹ when the beam is tilted by the weight g¹, and arm h¹×
releasing the pendulum p² in like manner as described with reference to the foregoing
mechanism. Fig. 12 shows the lever-arms h¹ and h¹×, and Fig. 13 the arm h¹× in the
position in which the release of the pendulum p² takes place. When the weight g²
has been shifted far enough to act on the right-hand end of the beam with a force
slightly exceeding the aforesaid 7 lbs. and to tilt the beam down at this end, the
tongue 2 allows the pall h² to drop and to engage by its beak e² with the first notch
of the disk y coming opposite to it, this being under the pre-supposed conditions the
eighth notch, counting the zero-notch as the first one of the series. The numeral-disk r²
is, however, adjusted to indicate 7 pounds.
In view of preventing the tongue t from striking against the edge t³ when, subse-
quent to the dropping of the lever-arm h, the tongue oscillates to the left, the tip
thereof is curved to the left so that it will pass above the said edge. For the like
reason the tip of the tongue t¹ is curved to the right, and that of the tongue t² again to
the left.
The registering-device shown by Figs. 6, 7 and 8, comprises in addition to the
numeral-disks r2, (which in this case have projecting characters) the printing-
lever s, the two friction-rollers u u¹ serving to draw forward a strip of paper x from a
roll r¹, the ratchet-wheel connected to the roller u, the lever v¹ carrying a pall
engaging in the teeth of the wheel v, and the bar w having a latch w¹ and arranged to
be raised by the aforesaid plate q, the said latch having a bevelled end-face which,
when the bar w is raised, acts against a bevelled projection on the vertical arm of the
lever s and thereby presses the horizontal arm of the same against the numeral-disks,
so that an impression of the numerals will be made on the strip paper & passed between
the lever and the disks. At its downward motion the latch w¹ rises on meeting the
projection on the lever, and, after it has passed the same, it is returned to its normal
position by a spring. The lever v¹ is actuated by a pin on the bar w, the strip & being
thus drawn forward through each upward stroke of the bar w, produced simultaneously
with the operation of returning to their initial positions the propelling-mechanisms of
the balance subsequent to a weighing-operation.
