Improvements in Automatic Weighing Machines and Delivery Boxes.
I EMIL UBRIG of the firm of "E. Ubrig & Co." of Westend, Berlin, Prussia,
Germany, Spring Balance & Scale Manufacturers 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 :-
This invention relates to an improved weighing machine with electrical escapement
for the weighing and indicating mechanism whereby the said weighing and indicating
mechanism will remain arrested until the weight of a coin introduced into a suitable
slot in the casing acts on a plate suspended on or provided with a sensitive spring and
closes or opens the electrical current in which an electro magnet is arranged which,
when excited, will attract or repel the armature of a lever and release a system of
catch levers and thus permit the operation of the weighing and indicating mechanism.
Figure 1 is an elevation of the parts of the improved weighing machine with the
case and upper part of the standard in section and the rack for operating the indicator
pinion attached to the rod b.
Figure 2 represents the like parts as shown in Figure 1 in released condition and
carrying out a weighing operation.
Figure 3 represents a like view of the weighing machine shown in Figure 1 and 2
with the rack or sector for operating the indicator pinion arranged to rest on a rail at
the upper end of the rod b.
Figure 4 to 10 represent modifications in which the battery is omitted in order to
effect a mechanical automatic weighing.
a is the casing of the weighing machine b the rod to which the weight applied to
the platform is transferred in known manner and which is forked at its upper end.
One end of each of the two weighing springs c c', is attached to one of these ends of
the rod whilst the upper ends are fixed to studs dd, attached to the casing a.
rack for operating the indicator pinion is either fixed to the rod or arranged to rest
on a rail or plate fixed to the upper end of the same.
The
The movement of the indicator is effected by means of a rack for sector f¹ which
gears into a pinion e attached to the spindle or arbor of the indicator.
The rack is attached to the forked end of the rod 6 and is guided by means of a

page_text: guide or in other suitable manner. The weighing and indicating mechanism is
arrested by the lever mechanism hh, ii, k, in the following manner.
The lever which turns around the fulcrum is provided with a slot n in which a
pin m in the rod b glides. The lever moves with the rod b of the weighing machine
and is so arranged that the same will lay horizontal or nearly so when the platform is
not loaded.
a"
'
In this position of the rounded end o, the lever k rests on the nose of a bell
crank lever i arranged on the fulcrum, the longer arm of which is also held in
horizontal position by means of a pin m' in the rod whereby the rounded off end q
of the lever arm lies on the nose of the two armed lever ', which moves around
the fulcrum 2. In this position of the levers h, k, the entire weight of the load
on the rod is taken up by the lever or its fulcrum. The releasing of the mechanism
for effecting a weighing and indication of the same is attained by means of a coin of
certain size and weight which must be inserted in a slot in the casing by the person
weighing or being weighed. The lever, forms the armature lever of an electro
magnet u the coils of which are arranged in the current of an electrical battery the
poles of which are on the one hand connected to a swinging metallic plate y and on
the other to a stud in the casing a. If the plate y is depressed by a coin inserted in
a slot of the casing and thus brought into contact with the stud the current will be
closed, the electro magnet u excited and the lever, attracted, whereby the
levers, and are released whilst the spring, draws the lever arm, up to the
stud g, so that the entire mechanism takes up the position represented in Figure 2
the weight acting on the rod 6 will put the weighing springs c, c', under tension and
show the weight of the person or object on the platform on the dial. The swinging
plate y is suspended from the spring (or lightly held in other suitable manner) the
tension of which is so arranged that the plate y only then comes in contact with the
stud when a coin for instance of the size and weight of a penny is inserted in
the casing a. This coin passes from the inclined plate y through the canal or shoot w
into a receptacle w¹. When the plate y has been freed from pressure the current will
be again interrupted the armature lever ', of the electro magnet will be drawn back
to the stop by the springs and the entire escapement mechanism or lever combination
again brought into gear by the power of the weighing springs when the rod ↳ rises.
The battery for producing the electrical force can be arranged in the weighing
machine itself or taken from any other suitable source of electrical power. An
electrical control apparatus can be applied to the weighing machine which will indicate
how many times the machine has been operated and thus the amount of cash which
ought to be found in the coin receptacle.
2
It will be evident that the parts can be so arranged as to free the escapement or
lever combination when the current is interrupted instead of closed.
As mentioned above, the rack for moving the pinion of the indicator need not be
attached to the weighing rod 6 but can for instance as shown in Figure 3 be arranged
to rest on the same only. The rod 6 is provided with a rail or plate b, on which the
friction roller, of the rack or toothed sector f' rests, which latter is attached to the
ratchet wheel, and turns with the same around the fulcrum or centre. The
continuous contact between the rack, and the rail, is attained through the weight
of the rack alone or can be facilitated by the application of a suitable spring. One
end of the two armed lever h h', which turns on the pivot h², is provided with a
tooth like projection and gears into the toothing of the ratchet wheel 3, whilst the
other end, forms the armature of the electro magnets u which are as aforesaid
excited when a coin introduced through the slot of the casing falls onto the plate y,
the circuit being thus closed, the electro magnets excited, the lever armature h
attracted and the arm / released from gear with the ratchet wheel 3, so that the rack
or sector, is free to follow the movement of the rod b. The parts for moving the
indicator being unconnected with the rod the weighing machine platform moves
independent on the same so that if a person steps upon the platform or places any
object on the same the weighing mechanism will be operated but only then indicated
on the dial when the indicator mechanism is released by an inserted coin. The

page_text: movement of the sector can be attained by suitably weighting the same so that it will
follow the movement of the weighing rod or a spring can be employed for like
purpose.
In the modifications represented in the Figures 4, 5, 6, the battery is omitted so that
a mechanical automatic weighing is accomplished.
a
The two armed lever h, Figure 4 is in this case provided with a tooth 4³, for
gearing with the ratchet wheel, of the sector f¹, and is held in equipoise by
counterweight G. The tooth h³, is released from its gear and the indicating mechanism
freed as soon as a coin inserted in the slot a as aforedescribed overcomes the weight of
the counterweight G. The opposite end of the lever has the coin receptacle which
with the lever and inserted coin will sink until the flap gl, of the coin receptacle K',
comes in contact with the stop t¹, whereupon the coin will be ejected from the
receptacle and the counterweight G will bring the lever back into its original
position and in gear with the ratchet 13. This return of the lever and its gearing
with the ratchet wheel, will not prevent the return of the sector or indicator as the
teeth will simply glide over the said tooth ³, by the force of the springs e c¹, as the
friction roller of the sector f¹ rests as aforesaid on the plate, attached to the rod b.
It will be evident that no weighing can be indicated until the indicator escapement
which is independent of the weighing rod is released by the insertion of a suitable
coin.
Figures 5 and 6 represent modifications of Figure 4 the sector being connected
to the lever hh, which in this case is preferably made in the form of a bow embracing
the ends of the said sector so as to allow the latter to gear freely with the pinion e of
the indicator and the ratchet wheel be omitted.
The weighing rod is also given a different form so that a cigar or cigarette
delivery apparatus can be combined with the weighing machine. This cigar or
cigarette delivery apparatus consists of an elongated canal like receptacle B which is
open at the top and is closed by a slide s, in which the cigars are arranged one above
the other. The slide s² sits on a lever which is pushed to one side by a projecting
piece of metal or stud 2 on the weighing rod when the same is depressed to effect a
weighing operation so as to allow a cigar to roll onto the inclined surface and
receive an impulse from the slide on its return after passing the stud u².
The cigars will remain in this position behind the plate
by the insertion of a coin when the same falls onto a dish or receiver outside the
casing. In order to facilitate the filling of the cigar or cigarette receptacle B the
entire delivery device can be hinged to the casing at y as shown more clearly in
Figures 8 and 9.
until the same is depressed
In the modification Figures 7, 8 and 9, the dial is covered by a sliding plate c**
which is only lowered so as to make the dial and indicator visible when a coin of
certain size and weight is inserted in the casing a.
This plate is suspended on cords steel bands or thin equivalents & running over and
attached to the pulleys or rollers r₁, and is balanced by the counterweights G
suspended on cords, chains or the like 2 running over the rollers or pulleys. The
weight of the inserted coin overcomes the weight of the counterweight G thus causing
the plate c*, to descend and expose the dial until the arm carrying the receptacle k
and counterweight w', comes in contact with the stop t', thereby ejecting the coin and
freeing the plate **, which is now drawn up by the counterweights G so as to again
cover the dial.
Figure 10 shows a modified arrangement of the rack which is connected to the
levers fh, so that the same only comes into gear with the pinion e of the indicator
when a coin is inserted and the lever h depressed. The lever his freed from the
coin in like manner as aforedescribed and the cigar or cigarette delivery apparatus
also operated in the same manner as above set forth.
In order to be able to readily fill the cigar cigarette or other receptacle B the
entire parts of the same with the exception of the incline 4, are arranged to turn on
the hinge y outwards as shown by the dotted lines Figure 8.
One disadvantage which could appear with the constructions as represented in the

page_text: foregoing Figures 1 and 2 is that it might be possible with cunning manipulation to
effect a second weighing and indicating without paying a second time.
If for instance a second person steps quickly onto the platform before the first
person has fully left the same the weight of the second person would be indicated by
the machine. In order to overcome this disadvantage the indicator arbor or spindle e
is made in two parts which are coupled together in appropriate manner.
Figure 11 represents the escapement partly in elevation partly in dotted lines with
the casing partly broken away and the upper part of the standard in section.
Figure 12 represents the projections or studs on the coupling discs.
Figure 13 is a side view of figure 11.
The indicator arbor or spindle consists of two parts e e¹ which are connected to each
other when the machine is in operation by means of two projections or studs e e
atiached to or made of one piece with the inner surfaces of the discs e²e³ which
are held in gear by means of the springs e as shown in figure 13.
The part e is as shown in the foregoing figures set in motion by the rack f by means
of the pinion attached to the said part el. A lever Barranged between the two discs e² es
turns on the spindle B', is so formed that it does not hinder the movement of the noses
or projectionse. The lower end of the lever B is in connection with the bell crank
lever 12 the one arm of which glides over the teeth of a rake B³ in such manner that
when the weighing rod brises the lever B is pressed to the one side but remains in its
original position or returns to the same when the weighing rod is depressed.
An arm which is in connection with the lever B by means of the spindle B
operates on a two armed lever C₁ which receives its movement from the coin in the
shoot 3. The coin reaches the shoot y which turns on the pivot y through the slot a
and shoot or canal presses the arm y' upwards and closes the current by a platinum
tip fixed to y¹ making contact with the plate v.
The magnets u will now attract the lever and release the lever K of the weighing
rod so that the weighing can be effected in like manner as described with reference to
figures 1 and 2. Should the weighing rod b be freed or rise only a trifle by variation
of the weight on the platform one of the teeth of B³ will come in contact with the bell
crank lever B2, which will force the lever B to one side, overcome the pressure of the
spring B and uncouple the two parts of the indicator arbor or spindle e e¹ and free the
projection or studs ee. The parts being thus freed so that a weight D attached to a
cord running over a pulley D' will immediately turn the indicator back to the zero
point and thus entirely prevent a second weighing without the introduction of a second
coin. The projections or studs ee are now again in contact and ready to effect a
second indication when released by the introduction of a suitable coin. Although this
device is shown in special application to electrical weighing machines it will still be
evident to all acquainted with this branch of industry that the device can be slightly
modified and applied to almost any kind of automatic weighing machine without in
any way departing from the tenor of my invention.
Insted of employing the discs e² e and the projections or studs ee it will be evident
that ordinary coupling jaws will effect a like purpose and I wish it to be understood
that the employment of the same could not be considered as departing from the tenor
my invention.

I EMIL ÜBRIG of the firm of "E. Ubrig & Co." of Westend, Berlin, Prussia,
Germany, Spring Balance & Scale Manufacturers 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 :-
This invention relatos to an improved weighing machine one of a class broadly
claimed by Percival Everitt in the specification of his patent 1884 13 December
No. 16433 wherein he showed the first machine of the kind. In my machine there
is an electrical escapement for the weighing and indicating mechanism whereby the
said weighing and indicating mechanism will remain arrested until the weight of a
coin introduced into a suitable slot in the casing acts on a plate suspended on or
provided with a sensitive spring and closes or opens the electrical current in which
an electro magnet is arranged which, when excited, will attract or repel the armature
of a lover and release a system of catch levers and thus permit the operation of the
weighing and indicating mechanism.
Figure 1 is an elevation of the parts of the improved weighing machine with the
case and upper part of the standard in section and the rack for operating the indicator
pinion attached to the rod b.
Figure 2 represents the like parts as shown in Figure 1 in released condition and
carrying out a weighing operation.
Figure 3 represents a like view of the weighing machine shown in Figure 1 and 2
with the rack or sector for operating the indicator pinion arranged to rest on a rail at
the upper end of the rod b.
Figure 4 to 10 represent modifications in which the battery is omitted in order to
effect a mechanical automatic weighing.
a is the casing of the weighing machine & the rod to which the weight applied to
the platform is transferred in known manner and which is forked at its upper end.
One end of each of the two weighing springs c c', is attached to one of these ends of
the rod b whilst the upper ends are fixed to studs & d', attached to the casing a. The
rack for operating the indicator pinion is either fixed to the rod b or arranged to rest
on a rail or plate fixed to the upper end of the same.
The movement of the indicator is effected by means of a rack for sector f¹ which
gears into a pinion e attached to the spindle or arbor of the indicator.
The rack is attached to the forked end of the rod b and is guided by means of a

page_text: guide .or in other suitable manner. The weighing and indicating mechanism is
arrested by the lever mechanism h, ii, k, in the following manner.
The lever which turns around the fulcrum is provided with a slot n in which a
pin m in the rod 6 glides. The lever moves with the rod b of the weighing machine
and is so arranged that the same will lay horizontal or nearly so when the platform is
not loaded.
In this position of the rounded end o, the lever rests on the nose p of a bell
crank lever, arranged on the fulcrum, the longer arm of which is also held in
horizontal position by means of a pin m in the rod & whereby the rounded off end
of the lever armi lies on the nose of the two armed lever h h', which moves around
the fulcrum . In this position of the levers hh, i, k, the entire weight of the load
on the rod b is taken up by the lever or its fulcrum. The releasing of the mechanism
for effecting a weighing and indication of the same is attained by means of a coin of
certain size and weight which must be inserted in a slot in the casing by the person
weighing or being weighed. The lever ', forms the armature lever of an electro
magnet the coils of which are arranged in the current of an electrical battery the
poles of which are on the one hand connected to a swinging metallic plate y and on
the other to a stud in the casing a. If the plate y is depressed by a coin inserted in
a slot of the casing and thus brought into contact with the stud the current will be
closed, the electro magnet excited and the lever, attracted, whereby the
levers hii, and kare released whilst the spring f, draws the lever arm i¹, up to the
stud g, so that the entire mechanism takes up the position represented in Figure 2
the weight acting on the rod will put the weighing springs c, c, under tension and
show the weight of the person or object on the platform on the dial. The swinging
plate y is suspended from the spring (or lightly held in other suitable manner) the
tension of which is so arranged that the plate y only then comes in contact with the
stud when a coin for instance of the size and weight of a penny is inserted in
the casing a.
This coin passes from the inclined plate y through the canal or shoot w
into a receptacle w¹. When the plate y has been freed from pressure the current will
be again interrupted the armature lever h', of the electro magnet will be drawn back
to the stopt by the springs and the entire escapement mechanism or lever combination
again brought into gear by the power of the weighing springs when the rod 6 rises.
The battery for producing the electrical force can be arranged in the weighing
machine itself or taken from any other suitable source of electrical power. An
electrical control apparatus can be applied to the weighing machine which will indicate
how many times the machine has been operated and thus the amount of cash which
ought to be found in the coin receptacle.
It will be evident that the parts can be so arranged as to free the escapement or
lever combination when the current is interrupted instead of closed.
As mentioned above, the rack for moving the pinion of the indicator need not be
attached to the weighing rod but can for instance as shown in Figure 3 be arranged
to rest on the same only. The rod is provided with a rail or plate 6', on which the
friction roller, of the rack or toothed sector f¹ rests, which latter is attached to the
ratchet wheel and turns with the same around the fulcrum or centre i*. The
continuous contact between the rack f¹, and the rail ', is attained through the weight
of the rack alone or can be facilitated by the application of a suitable spring. One
end of the two armed lever h h, which turns on the pivot 2, is provided with a
tooth like projection and gears into the toothing of the ratchet wheel 3, whilst the
other end h, forms the armature of the electro magnets u which are as aforesaid
excited when a coin introduced through the slot of the casing falls onto the plate y,
the circuit being thus closed, the electro magnets excited, the lever armature,
attracted and the arm released from gear with the ratchet wheel ³, so that the rack
or sector 1, is free to follow the movement of the rod b. The parts for moving the
indicator being unconnected with the rod the weighing machine platform moves
independent on the same so that if a person steps upon the platform or places any
object on the same the weighing mechanism will be operated but only then indicated
on the dial when the indicator mechanism is released by an inserted coin.
The

page_text: movement of the sector can be attained by suitably weighting the same so that it will
follow the movement of the weighing rod or a spring can be employed for like
purpose.
In the modifications represented in the Figures 4, 5, 6, the battery is omitted so that
a mechanical automatic weighing is accomplished.
The two armed lever h, Figure 4 is in this case provided with a tooth ³, for
gearing with the ratchet wheel, of the sector f¹, and is held in equipoise by a
counterweight G. The tooth h³, is released from its gear and the indicating mechanism
freed as soon as a coin inserted in the slot as aforedescribed overcomes the weight of
the counterweight G. The opposite end of the lever has the coin receptacle which
with the lever and inserted coin will sink until the flap g, of the coin receptacle K¹,
comes in contact with the stop t', whereupon the coin will be ejected from the
receptacle and the counterweight G will bring the lever back into its original
position and in gear with the ratchet 3. This return of the lever hand its gearing
with the ratchet wheel 3, will not prevent the return of the sector or indicator as the
teeth will simply glide over the said tooth ³, by the force of the springs cc, as the
friction roller of the sector ¹ rests as aforesaid on the plate b, attached to the rod b.
It will be evident that no weighing can be indicated until the indicator escapement
which is independent of the weighing rod is released by the insertion of a suitable
coin.
Figures 5 and 6 represent modifications of Figure 4 the sector f¹ being connected
to the lever h¹, which in this case is preferably made in the form of a bow embracing
the ends of the said sector so as to allow the latter to gear freely with the pinion e of
the indicator and the ratchet wheel be omitted.
The weighing rod is also given a different form so that a cigar or cigarette
delivery apparatus can be combined with the weighing machine. This cigar or
cigarette delivery apparatus consists of an elongated canal like receptacle B which is
open at the top and is closed by a slide s, in which the cigars are arranged one above
the other. The slide sits on a lever which is pushed to one side by a projecting
piece of metal or stud u² on the weighing rod when the same is depressed to effect a
weighing operation so as to allow a cigar to roll onto the inclined surface /* and
receive an impulse from the slide on its return after passing the stud u².
The cigars will remain in this position behind the plate e until the same is depressed
by the insertion of a coin when the same falls onto a dish or receiver outside the
casing. In order to facilitate the filling of the cigar or cigarette receptacle B the
entire delivery device can be hinged to the casing at y as shown more clearly in
Figures 8 and 9.
In the modification Figures 7, 8 and 9, the dial is covered by a sliding plate **
which is only lowered so as to make the dial and indicator visible when a coin of
certain size and weight is inserted in the casing a.
This plate is suspended on cords steel bands or thin equivalents ¹ running over and
attached to the pulleys or rollers, and is balanced by the counterweights G
suspended on cords, chains or the like 2 running over the rollers or pulleys The
weight of the inserted coin overcomes the weight of the counterweight G thus causing
the plate c*, to descend and expose the dial until the arm carrying the receptacle k
and counterweight w¹, comes in contact with the stop t¹, thereby ejecting the coin and
freeing the plate c*, which is now drawn up by the counterweights G so as to again
cover the dial.
Figure 10 shows a modified arrangement of the rack which is connected to the
levers, so that the same only comes into gear with the pinion e of the indicator
when a coin is inserted and the lever h depressed. The lever his freed from the
coin in like manner as aforedescribed and the cigar or cigarette delivery apparatus
also operated in the same manner as above set forth.
In order to be able to readily fill the cigar cigarette or other receptacle B the
entire parts of the same with the exception of the incline, are arranged to turn on
the hinge y outwards as shown by the dotted lines Figure 8.
One disadvantage which could appear with the constructions as represented in the

page_text: foregoing Figures 1 and 2 is that it might be possible with cunning manipulation to
effect a second weighing and indicating without paying a second time.
If for instance a second person steps quickly onto the platform before the first
person has fully left the same the weight of the second person would be indicated by
the machine. In order to overcome this disadvantage the indicator arbor or spindle e
is made in two parts which are coupled together in appropriate manner.
Figure 11 represents the escapement partly in elevation partly in dotted lines with
the casing partly broken away and the upper part of the standard in section.
Figure 12 represents the projections or studs on the coupling discs.
Figure 13 is a side view of figure 11.
The indicator arbor or spindle consists of two parts e e¹ which are connected to each
other when the machine is in operation by means of two projections or studs e e
attached to or made of one piece with the inner surfaces of the discs e² e³ which
are held in gear by means of the springs e as shown in figure 13.
The part e¹ is as shown in the foregoing figures set in motion by the rack f by means
of the pinion attached to the said part el. A lever Barranged between the two discs e² e³
turns on the spindle B', is so formed that it does not hinder the movement of the noses
or projections. The lower end of the lever B is in connection with the bell crank
lever B2 the one arin of which glides over the teeth of a rake B³ in such manner that
when the weighing rod rises the lever B is pressed to the one side but remains in its
original position or returns to the same when the weighing rod is depressed.
An arm C which is in connection with the lever B by means of the spindle
operates on a two armed lever C which receives its movement from the coin in the
shoot y. The coin reaches the shoot y which turns on the pivot y through the slot.
and shoot or canal al presses the army' upwards and closes the current by a platinum
tip fixed to y' making contact with tho plate v.
The magnets u will now attract the lever h¹ and release the lever K of the weighing
rod so that the weighing can be effected in like manner as described with reference to
figures 1 and 2. Should tho weighing rod & be freed or rise only a frifle by variation
of the weight on the platform one of the teeth of 133 will come in contact with the bell
crank lever B2, which will force the lever B to one side, overcome the pressure of the
spring and uncouple the two parts of the indicator arbor or spindle eel and free the
projection or studs ese. The parts being thus freed so that a weight D attached to a
cord running over a pulley D will immediately turn the indicator back to the zero
point and thus entirely prevent a second weighing without the introduction of a second
coin. The projections or studs e e are now again in contact and ready to effect a
second indication when released by the introduction of a suitable coin. Although this
device is shown in special application to electrical weighing machines it will still be
evident to all acquainted with this branch of industry that the device can be slightly
modified and applied to almost any kind of automatic weighing machine without in
any way departing from the tenor of my invention.
Instead of employing the discs e² e³ and the projections or studs es es it will be evident
that ordinary coupling jaws will effect a like purpose and I wish it to be understood
that the employment of the same could not be considered as departing from the tenor
of my invention.
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 am aware of the
Patents granted the 13 December 1884 No. 16433 for "Improvements in weighing
machines to Percival Everitt & the 13th April 1886 No. 5139 for "A novel construc-
tion of case for displaying objects or exhibiting notices for a limited time" to Thomas
Cooper & of the Specifications in connection with those patents and I make no claim
to anything described or claimed by those specifications but what I do claim is :-
1. A weighing machine in which the weighing and indicating mechanism only
then operates when the weight of a coin introduced into the machine depresses a
suspended plate and closes the circuit of a battery so as to excite an electro magnet the
armature lever of which frees the escapement for the weighing rod and after the

page_text: weighing operation has been completed and the circuit opened the parts will automatically
return to their original position, substantially as shown and described.
2. A weighing machine in which the weighing and indicating mechanism only
then operates when the weight of a coin introduced into the machine depresses a
suspended or oscillating plate and opens the circuit of a battery so as to shut off an
electro magnet the armature lever of which frees the escapement for the weighing ro
and after the weighing operation has been completed and the circuit closed, the parts
will automatically return to their original position, substantially as described and
shown.
3. In automatic weighing machines the indicating mechanism of which is under the
control of an electric battery the arrangement and construction of the parts in such
manner that the indicating mechanism is not in direct connection with the weighing
mechanism and only then operates in combination with the said weighing mechanism
when the electrical circuit is closed by the insertion of a coin into the said machine,
substantially as described and shown.
4. In automatic weighing machines the indicating mechanism of which is under
control of an electrical current the arrangement and construction of the parts in such
manner that the indicating mechanism is not in direct connection with the weighing
mechanism and only then operates in combination with the said weighing mechanism
when the electrical circuit is opened by the insertion of a coin into the said machine
substantially as described and shown.
5. The construction arrangement and employment of the parts as represented in
Figure 4, substantially as described and shown."
6. The arrangement application and employment of the device for operating the
pointer or indicator when a coin of certain size and weight is inserted in the machine
said device being arranged to operate independently of the weighing machine proper
and composed of a toothed sector which gears with the pinion e of the pointer or
indicator and by means of its ratchet wheel with the tooth or projection of a
balanced escapeinent lever h¹ carrying at the one end the coin receptacle and at the
other a counterweight G the lever end of the aforesaid sector being provided with a
friction roller which rests on or comes in contact with the plate 6 of the weighing
rod b, substantially as described and shown.
7. The construction application and employment of the parts of my improved
weighing machine as shown in Figures 5 and 6 alone or in combination with a device
for delivering cigars cigarettes or other small objects substantially as shown and
described.
8. The construction application and employment of the weighted escapement
lever which embraces the rack gearing with the pinion e and also carries the
anti friction roller alone or in combination with the delivery apparatus for cigars
cigarettes and other small articles composed of the receptacle B lever 12 slide s² and u²
and incline 4, substantially as described and shown.
9. The construction arrangement and application of the parts of my improved
weighing machine as represented in the figures 7 8 and 9 alone or in combination
with the cigarette or cigar delivery apparatus, substantially as described and
shown.
10. In an automatic weighing machine the application and arrangement of a sliding
cover *, which only descends and discloses the dial when a coin of suitable size and
weight is inserted in the apparatus substantially as described and shown.
11. The construction arrangement and application of the sliding dial cover c**
with a device for delivering cigars cigarettes or other small objects on the parts being
released by the insertion of a coin into the apparatus substantially as described and
shown.
12. The arrangement and application of the weighted lever h and the rack f
levers and the support for the fulcrum / alone or in combination with the device
for delivering cigars cigarettes or other small objects substantially as described and
shown.

page_text: 13. In automatic weighing machines the application and employment of an indicator
arbor or spindle composed of two or more parts substantially as described and shown.
14. In automatic weighing machines the construction application and employment
of the discs e² e³ studs or projections es e or any other suitable coupling device for
coupling the spindle or arbor to the indicator substantially as described and shown.
15. In automatic weighing machines the employment of a rake like device in
connection with the rack f for operating a bell crank lever B2 for uncoupling the parts
of the arbor or spindle as soon as a variation in the weight on the platform takes place
or any mere modification of the same, substantially as described and shown.
16. In automatic weighing machines the application of a cord drum D¹ and weight D
which are attached to the same or an equivalent torsional or other spring to one part
of the subdivided spindle or arbor to the indicator so as to return the indicator to the
zero point when the parts are uncoupled, substantially as described and shown.
17. The general construction arrangement employment and combination of the
parts of my improved device with the spindle or arbor of two or more parts and
mechanism for coupling and uncoupling the same in order to prevent fraudulent
weighing operations, substantially as described and shown.
