COMPLETE SPECIFICATION
Apparatus for Delivering Weighed Parcels of Tobacco or other
Fragmentary Materials
I, ALBERT LEROY MUNSON, of No 122 Centre Street in the City, County
and State of New York United Sates of America Manufacturer, do herebv
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 apparatus for weighing and delivering successive parcels
of fragmentary material to be made up into packages, and it is especially applicable
for feeding tobacco to machines by which it is packed into cigarette or other form
I shall describe apparatus according to my invention referring to the accompanying
drawings in all the figures of which the same reference letters are employed to
denote the same parts
Fig 1 is a longitudinal section, Fig 2 shews part thereof with the weighing
scale canted, Fig 3 is a plan on the line X X Fig 4 1 an end view and
Fig 1s a part side view
A and B arc pulleys driven by bands from any convenient moto overhead, A is
fixed on the shaft of a spiked roller a which revolves in the direction of the
arrow a¹ R revolves freely on the shaft of a spiked roller b, and on this shaft
there is fitted on a feather a clutch b' which is usually held by a spring b² acting

machine any convenient distance to pass round another 1oller like
frame of the machine is fixed an electro magnet E the armature e of which is
attached to the lever b³ The coils of the magnet E are connected to a battery or
other source of electricity by suitable leads one of which is interrupted by a switch
consisting of a pan of mercury cups F Into the mercury in these cups dip a pair
of prongs which are fixed insulated on a lever G having adjustable upon its one
arm a weight g and having its other arm terminating in a cross head g¹ which is
pivotted to lugs g² projecting down from a weighing scale H A spring g has its
one end attached to one of the lugs g² and its other end to a rod g' extending down
fiom the lever G On the brackets go on which is pivotte the lever G is also
On one arm of the
pivotted a rocking shaft carrying a lever K and in arm k
lever K is fixed an armature kabove an electromagnet ³, the other arm is held
down by a spring and has fixed on it one end of another sping the other end
of which is attached to one arm of a bell crank A³ the other aim of which beais.
against a pin on the side of K A vertical arm projects up from a rocking
shaft which has another vertical arm 2, both these arms having the upper ends
made as hooks, also the aim h near its upper end has a curved slot in which works
The coils of the electio magnet k³
a pin projecting from the side of the lever K
are connected to a source of electricity through a switch which may be worked by
hand or by some reciprocating part of the cigarette or other packing machine
which is supplied with weighed parcels of tobacco or other inaterial
I shall describe the operation of the apparatus as for supply of a cigarette
making machine.

Assuming the fork f to be immersed in the mercury of the cups F and the
dynamo machine or battery to which they are connected to be in action, assuming
also that the pulleys A and B are caused to revolve by bands from a suitable
motor, then the magnet E being energised attracts its armature e moving the
lever b³ so as to engage the clutch with the boss of the pulley B The roller b
is thus caused to revolve and through the skew gear b and c and the worm gear c²
and c³, the roller C is also caused to revolve slowly moving the apron D Tobacco
strewed on the apron D is thus advanced and passed between the roller C and a
pressing roller P which is mounted on arms pl pressed down by springs p
tobacco as it passes from between C and P is caught by the spikes of the roller b
and tossed over within the casing Q some of it descending directly and some of it
being moved by the spiked roller a down a hopper q, to be received on the scale H
The relative position and distance of the rollers a and b may be varied according
to the nature of the material dealt with, and additional picker rollers may be
introduced When the quantity received in H ovei bilances the adju ted weight g
the scale H descends rising the fork fout of the mercury thus rendering the
electro magnet E inert, whereupon the spring becauses the clutch b¹ to be disengaged
and thus the 1ollers bind and the apron D cease to move, the feed of tobacco
being thus arrested The scale having descended rests on the fork of a
column, two pins projecting at each side of the lugs g², being then under the
level of the hooks of the atms h and 2 When by means of a switch worked by
hand or by come suitable part of the cigarette machine the electromagnet k² is
energised it attracts its armature k¹ thus raising the lever arm K the pin on its
side moving up the curved slot of the arm h causes the arins h and h² to move so as
to bring the hooks over the pins h and thus prevent them from rising
By the
farther ascent of the lever K, the top of the uptight arm of the bell crank ³
engaging a pin projecting from the side of the lug g² pushes that pin up and
consequently causes the scale H to turn upon the pins h as pivots canting it to the
position shewn in Fig 2 the contents of H being thus discharged In vider
that the movement of K may not take place too suddenly the arm k has a toothed
1ack gearing with a pinion on the axis of an escapument wheel k engaged by a
weighted anchor k as K ascends the wheel * is caused to revolve causing the
anchor to oscillate, and its oscillations retard the movement of K When
the circuit of the electiomagnet is opened either by hand or automatically by the
cigarette mak ng machine, the lever K descends releasing the scale H from the bell
crank and the hooks of h and 2 and, as the scale is now relieved from its load
it rises and the fork f again dips into the mercury so as to close the circuit of the
electro magnet E whereupon the operation of the apparatus is repeated
Although I have described the operation as for feeding tobacco to a cigarette
making machine, obviously fragmentary material other than tobacco might be
weighed out in the same way and the parcels of material discharged from the
scale H might be made up into packages by hand or might be led by a travelling
apron or otherwise to feed any machine adapted to deal with them
Having now particularly described and ascertained the nature of my said inveu-
tion and in what manner the same is to be performed, I declare that what I
claim is
1 In an apparatus for delivering weighed parcels of tobacco or other fragmentary
material, the combination of a travelling apron, a pan of feeding rollers, picker
1olleis, a hopper leading to a scale mounted on an adjustably loaded lever, provided
with an electric switch, an electromagnet, clutch and armature lever with spring
and diving pulleys arranged and operating substantially as described
2 In apparatus for delivering weighed parcels of tobacco or other fragmentary
material, in combination with the scale mounted on a loaded lever, an electr
magnet and its armature level carrying a bell crank, a pair of hooked ar ns one of
which has a curved slot engaged by a pin on the armature lever, springs for the

substantially as described
