COMPLETE SPECIFICATION filed by the said Benjamin Joseph Barnard
Mills at the Office of the Commissioners of Patents, with his Petition,
and Declaration, on the 21th October 1871, pursuant to the 9th
Section of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BENJAMIN
JOSEPH BARNARD MILLS, of the Firm of Harris and Mills, of 35,
Southampton Buildings, in the County of Middlesex, Patent Agent, send
greeting.
WHEREAS I am in possession of an Invention for “ ImproVEMENTS IN
) MACHINERY FOR MAKING PAPER and othla Boxɛ³,” and have petitioned Her

page_text: Majesty to grant unto me, my executors, administrators, and assigns,
Her Royal Letters Patent for the same, and have made solemn Decla-
ration that it has been communicated to me from abroad by Henry
Renno Heyl, of Philadelphia, in the State of Pennsylvania, United States
of America, Mechanical Engineer.
NOW KNOW YE, that I, the said Benjamin Joseph Barnard Mills,
do hereby declare that the following Complete Specification, under my
hand and seal, fully describes and ascertains the nature of the said
Invention, and in what manner the same is to be performed, in and by
the following statement thereof, that is to say :—
The object of the machine is to produce from pasteboard, paper, and
other analogous material properly cut or prepared a paper or other box
complete.
The
The pieces of pasteboard from which the boxes are to be made are
placed directly over the machine in a suitable box with automatic feed
appliances, so that they can be brought down one by one at cach
revolution of the machine directly behind a crimping frame or former
and in front of a reciprocating plunger, both of which are adjustable in
size and shape according to the desired proportions of the boxes. The
plunger then moves forward, pressing the pasteboard through the
opening in the crimping frame or former, which being barely large
enough to admit of its passage bends the pasteboard close to the plunger,
where it is held by a set of nippers attached to the plunger.
plunger then stops its forward movement a short distance in front of the
frame or former to receive the covering paper. The reciprocating motion
of this plunger is obtained through levers and connecting rods from
cranks on either end of a central countershaft beneath the table. While
the reciprocating plunger is in its advanced or forward position it
receives one complete rotation by means of a mutilated or segment cog
wheel or other suitable mechanism for the purpose of applying the
pasted covering paper to the pasteboard frame. The rotary and the
rectilinear motions of the plunger are alternate and occupy the time,
with the exception of a short space while changing motion. A strip of
paper of sufficient length to go entirely around the box is laid upon a
reversible platform which takes paste from a reservoir in which it turns,
and is then caught by and laid around a pressing wheel with the pasted
side outwards. From this wheel it is transferred to the sides of the
box by a forward movement of the pressing wheel (until it rests against

page_text: the box) and a revolution of the plunger upon which the box frame is
secured. The pasting platform is reversed at each stroke of the machine,
so as to take a new supply of paste from the trough within which the
said platform turns. The box with the covering paper around it is
carried forward by the plunger into a folding frame (which is also
adjustable in size and shape and likewise in position) where the cover
paper is lapped around against the bottom of the box by a set of leaves,
rollers, or folders, which move inward across the bottom as the box is
pressed upon them. The plunger then returns to its first position, the
box being discharged from it by the aid of a pusher rod and left in the
folding frame, which then rocks over into a horizontal position directly
under a vertical plunger.
The next operation is to fold the upper edge of the cover paper over
the top and down into the inside of the box. This is done by the inward
and downward motion of the fect of the vertical plunger as they press
down into the box.
339
The boxes and covers for the same are made by similar operations of
proper dimensions to adapt one to fit within the other. Each is finished
by the application of a piece of cover paper to its flat face. This may or
may not consist of a printed label, but for convenience in description
will be called the " label." The "label" may be applied by pasting
either its own surface or that of the box to which it is to be affixed, and
then pressing the box on to it by means of the vertical plunger already
described or a separate plunger or any other suitable appliance, as the
particular arrangement of the machine or the kind of boxes to be made
or other circumstance may render most convenient.
The Invention further relates to means for holding the horizontal
plunger, pressing wheel, folding frame, and other parts in proper
positions.

1, 1, are a fast and loose pulley driven by belting from a countershaft
or in any convenient and proper manner. They are fastened on a
shaft 2 which carries a worm 3 and pinion 4. The worm 3 engages
with a worm wheel 5 journalled transversely thereto in a traverse
between the two principal frames at the end of the machine. A mutilated
wheel 6 is also keyed on the shaft which carries the wheel 5 and
engages during one-half of its revolution with a wheel 7 through a
transfer wheel between the two.
The wheel 7 is journalled in bearings on the table 8, and its hollow
axis carries a square plunger shaft 9, which is operated in a manner to
be herein-after described.
The pinion gears with a wheel 10, which, through the medium
of a pinion 11 rotates the wheel 12. The last-mentioned wheel runs
loosely on a shaft 13 which carries on cach end outside of the
principal frame a crank 14. The crank shaft 13 receives motion from
the wheel 12 through a pawl 15 fulcrummed thereon, which is inter-
mittingly engaged in a notch in a side wheel 16 fastened to the crank
shaft.

page_text: The worm wheel 5 has a pin 17 on its side which at cach revolution
raises a lever 18 fulcrummed on the inside of the main frame, and
connected by a rod 19 to the arm 20 of a shaft 21 journalled beneath
the table 8. The other end of the shaft 21 is provided with a stem 22
to engage with the tail of the pawl 15 and lift its nose out of the notch 5
in the side wheel 16, uncoupling this from the wheel 12, and allowing
the latter to rotate by itself. The wheel 16 which drives the cranks 14
is thus allowed to rest until the nose of the pawl again engages in a
notch of the side wheel 16. This stoppage of the crank at its uppermost
point arrests the forward movement of the plunger shaft 9 at half 1
stroke to allow time for the rotation of the plunger for the purpose of
applying the wrapper to the box, as herein-after explained.
The movement of the cranks 14 through the rods 23 operates
levers 24 fulcrummed to the lower part of the main frame of the
machine, which levers draw forward rods 25 connected to a head ]
piece 26 fastened above to the square hollow plunger shaft 9, which
contains the pusher rod 27, and below to a rod 28, which operates the
locking device of the moulding frame 34, and also the folding leaves of
the same, as herein-after described.
The connection between the head piece 26 and shaft 9 is effected 2
through a forked piece 29 attached by a screw 30 at its lower cnd and
by an adjusting screw 31 near its upper end to the head piece 26.
The forked piece 29 carries a yoke 32 which rests in a gland or notch
in the neck of the plunger shaft 9.
The adjusting screw 31 affords means of regulating the position of
the plunger relatively to the folding leaves 134 to allow for the variation
in the thickness of pasteboards used; 33 is a spiral spring to press the
plunger shaft as far forward as permitted by the set screw 31.
The moulding frame 34 turns on a shaft 41 and is elevated to vertical
or lowered to horizontal position by means of the wheel 35 having two
diagonal grooves nearly on opposite sides of its periphery for receiving
a pin 36 on the arm 37, which is pivotted near the mid length of a
lever 38 connected to a forked rod 39, the ends of which are jointed to
arms 40, 40, secured rigidly to the moulding frame and projecting below
the hinge 41 on which it turns.
The wheel 35 is secured to a sleeve in common with the worm wheel 5
and the gear wheel 6 by which the rotary movement of the plunger
is produced.

page_text: The sides 12 of the feed box are adjustable at any necessary distance
apart by any suitable means. The follower 43 is drawn forward
by a cord 44 passing over pulleys beneath the box and having an
attached weight 45. The said follower is guided by a longitudinal
slot 46 in the middle of the box, as illustrated in Figure 12.
At the bottom of the front part is a transverse slot or opening 47
through which each successive blank is pushed downward by the
vertically reciprocating feeder 4S to be submitted to the action of the
horizontal plunger 60 which pushes it forward into the crimping frame
by which the four sides of the blank are turned up so as to give
approximately the size and shape of the box, as herein-after described.
The feeder 48, which successively carries down the blanks, works
perpendicularly in a slot 19 at the front of the box, and is operated by
a cord 50 passing over pulleys 51 near the top and bottom in front of
the box, and wound upon a spirally grooved pulley 52. The rotation
of the pulley 52 to depress and elevate the feeder 18 is effected by means
of a bell-crank lever 53 (see Figure 13) upon whose upper arm is a
toothed segment 54 gearing with a pinion 55 attached to the side of the
pulley 52.
The horizontal arm of the bell-crank lever is connected by a rod 55
to a lever 56 pivotted to the side of the machine, as shown in Figure 3.
A projection 57 on the end of the crank 14 strikes the end of the
lever 56 so as to elevate the horizontal arm of the bell crank 53 and
thus draw down the feeder 48. The reverse movement to elevate the
feeder is effected by a pin indicated by dotted outline in Figure 3 pro-
jecting from the inner face of the connecting rod 23. This pin depresses
the lever 56 by engaging over a ledge or flange 58 projecting from said
lever. At the moment when this blank has reached its lower.position
it is arrested by an adjustable stop 58 and is brought directly opposite
the opening in the crimping frame 59, the forward movement of the
plunger 60 is commenced, pushing the blank through the crimping
frame, which throws the projecting sides of the blank against the sides
of the plunger 60, and as the cam lever 61 on the plunger shaft 9.
arrives at the cam-shaped opening 62 in the hollow shaft it is turned so
as to assume a position longitudinal to said shaft, pushing forward the
sliders 63 which are connected to the moveable head 64 at back of the
plunger 60.

The plunger 60 is made up. of moveable corner sections, as shown in
Figures 8, 14, and 15, adjusted by set screws to regulate the area of said

sections contain the nippers 65 that hold the pasteboard to its place on
the plunger while the covering paper is being pasted around it. In
order to grasp the pasteboard the nippers 65 are moved forward and
inward all at once by the action of the moveable head or plate 64 against
the nipper rods 60 and the movement of the latter on the inclined
planes 67 within the plunger, see Figure 14. The nippers 65 may be
shifted to any position in their grooves by turning the screw rods 66 on
which they are set. This adjustment adapts them for any desired depth
The forward movement of the plunger is still continued until
it arrives directly opposite to the face of the pressing cylinder 68, when
this movement is suspended and a rotary motion is communicated to it
in the following manner:-At the moment when the pawl 15 by which
the fast and loose wheels are engaged is lifted out of its notch by the
stem 22, operated from the worm wheel 5 on the inner side of the
mutilated wheel 6, the toothed part of the latter becomes engaged with
the wheel 6 turning the wheel 7 and causing the rotation of the plunger
shaft 9. The box body being clamped to the plunger is held against
the pressing cylinder 68 which is pressed up thereto by means of a fusce
chain 69, attached at one end to a sliding carriage 93 in which said
cylinder is journalled, and passing over a pulley 70, counterbalanced by
weights 71, 72. The preponderance of the weight 71 presses the

pressing cylinder 68 is caused to alternately advance and recede upon
the horizontal frame 73 by means of a chain 74 and wheel 75 actuated
as herein-after described.
76 is a reversible pasting platform journalled within a paste reser-
voir 91, and having two flat and two curved sides. On the exterior part
of its axis is a ratchet wheel 77 of two teeth and a loose cog wheel 78
which is caused to engage with the same by a pawl and spring during
a part of the rotary motion of the table, and released therefrom during
another part, that is, when the flat sides are horizontal. The loose
wheel 78 gears with a rack 79 which is caused to traverse the frame
alternately back and forth by means of an arm 80 attached to an upright
shaft 81, which by means of a double jointed arm 82 is connected to a
disc 83 on a bevel wheel 84, gearing with a bevel pinion 85. The

page_text: wheel S1 runs loose on the shaft of the disc S3 and moves it by means
of the pawl SG, which by a spring S7 is pressed inward to cause it to
engage with a projection between the disc S3 and wheel 81, shown by
dotted line in Figure 5. The said pawl is lifted out of contact with said
projection by striking a curved swinging arm 88 when said arm hangs
in vertical position, being again engaged at each alternate rotation by
reason of the arm S8 having been deflected by contact with its upper
end of a pin S9 projecting from the connecting rod 23, as shown in
Figures 3, 5, and others. The motion of the wheel 81 also produces
the movement of the weighted chain 69, the arrangements for engaging
and disengaging being so adjusted that at the moment when the
cylinder 68 is stationary and pressed against the plunger 60 the said
cylinder is beyond the reach of the pasting table and of the mechanism
by which it is rotated to take the paper from said table as herein-after
explained. At each forward movement of the rack 79, which imparts
a semi-rotation to the pasting platform, a scraper 90, Figure 8³, is carried
over the said platform without contact therewith. At the reverse
movement of the rack when the platform remains stationary the said
scraper is drawn across the face of the platform to remove surplus paste
therefrom into the reservoir 91. A piece of paper adapted for a wrapper
being half an inch wider than the depth of the box to adapt it to lap
above and below is then laid on the platform with its inner side down.
92, Figure 3, is a stop to steady the platform with one of its flat sides
up. The pressing cylinder 68 is rotated within the sliding carriage 93
by a pinion 94 on its shaft gearing with an intermediate wheel 95, driven
by a pinion 96 attached to a larger wheel 97 which gears with a
stationary rack 98 as the carriage is moved back and forth by the
chain 69.
On the periphery of the pressing cylinder 68 is a spring clip or
nipper 99 which as the said cylinder reaches the backward extremity
of its stroke is opened to receive the projecting end of the wrapper
paper by the following means:-A projection 100 upon the carriage 93
strikes the upper end of a bell-crank lever 101, causing it by the
connecting rod 102 to suddenly depress a knocker 103, which strikes
an arm 101 projecting from the nipper 99 at the proper instant to
cause said nipper to seize the end of the paper. The carriage 93 is then
advanced again, the cylinder 68 being rotated forward by the gearing
before described. The wrapper is thus taken from the platform 70

page_text: and laid upon the periphery of the cylinder 68 with the pasted side out-
wards, its rear end being held by spring fingers 105, Figure 7, mounted
on an arm 100. The arm is attached to a loose collar 107, Figure 8
To adapt the fingers to be changed in position to suit wrappers of
varying length the arm is made adjustable on the collar 107, and to
give the fingers the necessary motion to catch and release the cover
paper the collar 107 is made capable of a limited rotation around the
axis of the cylinder 68. A spring pulley 109 upon the cylinder con-
nected by double belts 110 to the collar 107 restores the fingers 105
to their normal position when they have been moved therefrom in
either direction and are again released. As the carriage reaches the
end of its forward stroke the gearing is carried beyond reach of the
rack 98, leaving the cylinder free to be turned by the plunger. Before
coming in contact with the latter the said cylinder is placed in proper
position by the action of the double bands 111, Figure 7, attached to
spring pulley 112, and is then steadily held by a T brace 113. The
cylinder being thus accurately adjusted the first part to come in contact
with the side of the plunger will be a projecting tappet 114 shown in
Figures 9 and 10. The pressure upon this tappet being communicated
through a lever 115 and rod 116 to a pivotted dog 117, forces the tail
of the latter outward against the clip 99, opening the said clip so as to
release the forward end of the pasted wrapper, which is pressed against
the box body upon the plunger 60 and caused to adhere thereto. The
plunger then begins its rotation, winding the cover from the cylinder
which turns freely, and presses the paper smoothly on all sides of the
box. The holding fingers 105 are governed by an outer finger 118,
Figures 7 and 8, attached to their head and resting on a guiding
flange 119 on the face of the cylinder 68. When the fingers 105 arc
to hold the paper the outer finger 118 drops into a depression in the
flange 119 as shown in Figure 8. As the latter end of the wrapper 3
approaches the box the arm 106 having been carried by the cylinder
in its rotation strikes a stop on the forward end of the carriage 93,
which arrests its motion and causes the continued rotation of the
cylinder to throw the finger 118 out of its cavity slightly raising
the holding fingers 105 and releasing the end of the wrapper. The 3
wrapper having been applied the carriage 93 is drawn back by the
chain 69. The cylinder 68 and arm 100 immediately resume their
normal positions; but the finger 118 being prevented by a spring
switch 120 from re-entering its depression in the flange from this

page_text: direction rests against the end of the said spring switch until the
cylinder having nearly completed its backward rotation brings the
arm 106 against the rear end of the carriage driving the finger 11S
over the spring switch 120 in readiness to pass under the forward end
of said switch as soon as the forward rotation of the cylinder lays
a new wrapper upon its periphery. The chain 74, by which motion is
communicated from the wheel 75 to the pulley 75, is attached at its
ends to the said wheel 75 by adjusting screw nuts 121.
A single
revolution of the crank wheel 122, Figures 4 and 6, imparts to the large
wheel 75 two opposite oscillations to retract and again advance the
carriage 93. This motion of the crank wheel 122 is imparted at each
fourth revolution of its shaft by a clutch movement 123, controlled by
compound grooves in the shaft, as shown in Figure 6. A dog 124 locks
the wheel 75 so as to prevent any considerable backward movement of.
the carriage 93 until the proper period, but sufficient play is allowed to
permit the cylinder to roll over the square corners of the plunger, the
said cylinder being constantly pressed against the plunger by the action.
of the weight 71. A complete revolution of the plunger 60 to take the
pasted wrapper from the cylinder 68 and roll it around the box is
produced by the teeth which extend around one half of the periphery of
the wheel 6. The rotary movement is suspended as the plain half of
the wheel 6 reaches the upper position, and the flat face of the segment
125 being then presented downward is caught and held by the T brace.
126, said brace being pressed upward by the spring 127, Figures 2, 5,
and 20. The forward movement of the plunger is then resumed by the
re-engagement of the fast and loose wheels 16, 12, causing the crank 14
to revolve as before explained. The relativo arrangement is such that
when the rotary movement of the plunger is suspended and its forward
movement resumed the rotation of the grooved wheel 35 in the direction
shown by the arrow will through the pin 36, Figure 2, and the pivotted.
levers 39 throw up the moulding frame 34 to receive the plunger. The
rod 28 is advanced by the head 26 simultaneously with the plunger.
When the moulding frame reaches a vertical position a pin 128 on said
rod raises the toggle levers 129, imparting a rocking motion to the
> connected cross heads 130 and 131, Figure 21, drawing down the
latch 132, which is attached rigidly to the shaft of the cross beads 131,
and is thus made to catch a hook 133 on the upper side of the moulding
frame. As the forward movement of the plunger carrying the box
progresses it forces the box within the said moulding frame, and as the

page_text: bottom of the box reaches the bottom of the frame a series of folding
leaves 131, Figure 25, are slidden inward simultaneously from all sides
turning in the projecting edges of the cover paper, and forming a lap
around the bottom of the box. The leaves work in suitable guides and
are advanced and retracted by arms 135, Figure 4, projecting from rock
shafts 136, which are geared together by segment pinions 137 at their
ends so as to move together. This movement of the folding leaves 131
is produced by a pin 138 on the rod 28 impinging against the short end
of a lever 139, Figure 25, pivotted beneath the table 8, as shown in
dotted lines in Figure 25, and connected by a chain 140 with an arm
141 on one of the rock shafts 136, Figure 21.
Rollers may be substituted for the leaves 131 on two or more sides if
preferred.
As the plunger reaches its foremost position springs 142 attached to
the rods 63 which operate the nippers, escape from the box or sleeve
within which the plunger shaft slides, sec Figure 15, and instantly
retract the nippers and release the box from the plunger. The plunger
is then drawn back by the continued movement of the crank 14, leaving
the box within the moulding frame 34, where it is held by a pusher 143
fitted to slide concentrically within the plunger 60. The stoppage of
the pusher is effected by a spring bolt 144 projecting through a slot 145
in the shaft 9, and engaging in a notch in the pusher rod (see Figures
16 and 17.) As the oblique end 146 of the slot reaches the bolt 144 it
presses it backward out of the notch in the pusher rod, when the pusher
is instantly retracted by a spring pulley 147, Figure 19, restoring the
pusher head to the cavity provided for it in the face of the plunger and
permitting the pusher to accompany the plunger in its retrograde
movement.
The operating parts are now in such relative positions that the groove
in the wheel 35 has commenced its backwardly pulling action on the
pin 36, causing through the connections before described the depression
of the arms 40, which support the moulding frame until this is lowered
into horizontal position directly below the vertical plunger, where its
outer edge rests on supports 148. A spring 223 is employed to counter-
balance the moulding frame so that it may move freely and rest in :
cither position.
The vertical plunger is made up of pendant arms 149, the lower ends
of which form the head of the plunger, and whose upper ends are hinged

page_text: to heel plates 150, which permit the arms to be pressed inward, but not
outward beyond a vertical position. The plates 150 may be adjusted'
radially within slots 151 in the supporting frame 152, Figures 21 and 21,
and secured by clamp nuts 153 to give any desired area to the plunger.
The arms 149 are pressed diagonally outward to their vertical positions
by springs 163 bearing against the plates 150.
The frame is sleeved on a vertical shaft 151 secured to the frame of
the machine, and is guided in its reciprocating motion by the rods 155.
at either side of the end of the frame.
The reciprocating movement is produced by connecting rods 156
attached above to a cross beam 157 and below to wrists 158 on
wheels 159, Figures 1, 5, and 21. Guides 160 are fastened to the anglo
pieces 150 at top and to collars 161, two of which are attached to each
of the arms 149. The enlarged lower ends of the arms are bevelled on
their outer sides to adapt them to pass into the bevelled upper part of
the moulding frame. Their under surfaces are formed with slots or
grooves 162 adapted to receive the projecting upper edges of the cover
paper, which projecting edges are by the descent of the plunger carried
down within the box and laid neatly and smoothly on the inside thereof,
and the box is carried down completely through the frame, the folding
leaves 134 being retracted from beneath it just before the plunger
reaches the bottom of the box.
The retraction of the folding leaves is effected by the following means:
-Projections 185, Figures 21 and 25, inside the rims of the wheels 159,
impinge against the ends of arms 186 connected by rods 187 to double
crank shafts 188 mounted on top of the frame, causing the free ends
of said crank shafts to descend suddenly and drive down arms 189
projecting from the rock shafts 136, thereby turning said shafts back-
ward. The crank shafts 188 are then retracted by springs 190.
As the box is carried down through the moulding frame its bottom is
received on horizontal rollers 191, Figures 26, 27, and 28, journalled in
a jointed frame 192. The pivots of the rollers work also in oblique
slots in a stationary guide frame 193, so that as the rollers arc forced
downward by the pressure of the box they run outward across its
bottom and are pressed against the sides thereof by the action of
springs 191.
The box bottom now rests on bars 195 in a frame 196, which slides
vertically in the frame 193, and when the box is carried to its lowest

page_text: position its bottom is brought in contact with a reversible pasting plat-
form 197, Figure 35, from which it receives a supply of paste in readiness
for the application of the "label."
As the plunger rises springs 198 drawing up the frame 196 retract
the box from the platform 197, and the arms 149 are pressed inward
out of contact with the box by the action of corner plates 164 attached
by oblique slots, through which pass pins in the collars 101, as shown in
Figures 21 and 22. The obliquity of the slots in the plates 161 causes
said plates to offer no resistance to the outward pressure of the plunger
arms while they are descending, but while they are ascending said
plates slipping downward project to a greater distance and bear rigidly
against the corners of the moulding frame above the top of the box,
and thus press the arms inward, overcoming the force of the springs 163
and leaving the box beneath the moulding frame.
The pitman wheels 159 are driven by chains 165, Figure 2, or their
equivalent, from a loose pulley 166, Figure 30, on the shaft 167, to
which pulley 160 a cog wheel 168 is attached. The shaft 167 carries
a fast wheel 169, from which motion is communicated at proper intervals
by a pinion 170 adapted to gear with both wheels 168 and 169 and
thrown in and out in the following manner :- The pinion 170 is 2
mounted loosely on a stud shaft 171 projecting horizontally from the
upper end of a bell-crank lever 172, sec Figures 2, 29, and 30. The
pinion is drawn and held out of gear by the action of one of
the wheels 159, a cavity in which, shown at its lower part in dotted
lines in Figure 29, catches a pin 173 projecting laterally from an 2
arm 174 on a rock shaft 175, which rock shaft, when at rest, is so held
by a spring 176 as to press the pin 173 against the inner face of the
rim of the said 159 and adapt it to catch in the cavity in said rim
when the cavity is brought to the pin by the rotation of the wheel.
Said rotary movement then draws the shaft endwise, and by the 3
chain 177 connecting said shaft with the bell-crank lever 172 draws
the pulley out of gear. The wheel is then caught and held against
retrogression by a dog 178 catching behind a pin 179, while its further
progression is prevented by the shaft 175 and attachments. This
position of the parts is shown in Figure 29.
When the time comes for the wheel to perform another revolution
the crank 14 pressing sidewise against an oblique tappet 180 on the
rock shaft 175 withdraws the pin 173 from its cavity in the wheel 159,
3

page_text: and also drives the shaft endwise toward the shaft 167 loosening the
chain 177 and permitting a weight 181 on the lever 172 to draw the
pinion 170 into gear. The parts are then locked in this position by a
knuckle-jointed bar 182, which is pressed down. by a spring 183. The
tappet 180 is immediately released from the crank 14, so that the
pin 173 is again thrown against the rim of the wheel, but it is now
out of reach of the notch or cavity therein. The wheels 159 are then
made to perform another revolution, carrying the plunger down and up
again when the pin 173 catching in the cavity in the wheel draws the
shaft 175 cndwise, the first effect of which is to straighten the chain 177.
The contact of the chain with a pin 184 on the jointed bar 182 throws
up the said bar, when the pinion is instantly pulled out of gear and
the wheels 159 are locked as before. It is manifest that springs and
weights may be substituted one for the other in various parts of this
movement.
The platform 197 receives paste from a reservoir 199, Figure 35,
through a roller 200, which is revolved in the said reservoir by friction
wheels 201, 202, between which the said platform and roller are
respectively mounted.
The wheel 201 are formed with flat parts 203 corresponding in
position and in radial distance from the axis 204 with the surface of the
platform or paste block 197, so that as the said platform in its revolution
reaches the roller 200 its surface will roll over the latter and receive
paste therefrom.
The intermittent rotation of the shaft 204 is derived from the shaft 13
through the endless chain 205 running on a clutch pulley 206, the said
pulley being thrown out of gear cach time the crank 14 rests in its
uppermost position. This result is effected by means of a spring
pawl 207 pivotted on a disc 208 keyed to the shaft 13 and engaging in
any one of the notches 209, Figures 33 and 34, but retracted by contact
with a stationary finger 210 when the platform is turned up. The
platform shaft is thus released from the driving mechanism, but is held
accurately in its proper position by a T brace 211, Figure 35, pressed
upward by a spring 212 against a flat surface prepared for it on the
chain wheel 213.
The apparatus for pasting the "labels" to the boxes may consist of

page_text: of slotted brackets 215, Figures 2 and 35, through which passes the
shaft 216 of the wheel 217 by which the plunger 218 is actuated, serving
to limit the upward and downward movement of the said box under
the opposing influences of the plunger and a weighted lever 219, on
which one end of the "label box rests and which adapts it to the
varying thickness of the pack of "labels."
"
The box 214 is provided on its inside with four pairs of holding
fingers 220 which may be adjusted at varying distances apart to suit
various sizes of "labels," and are pivotted so as to yield to the influence
of springs 221 by which their lower ends are held against corners of the
pack of labels" when placed within the box. The "labels
held in concentric position.

are thus
A paper box, its bottom having been covered with paste in the
manner before described, is placed by hand over the mouth of the
"label" box, and by the downward movement of the plunger 218 is
forced against the upper one of the "labels to become firmly attached
thereto, the fingers 220 opening sufficiently under the pressure to release
the "label" on top but being immediately closed down on those below
by the springs 221.
The plunger 218 is kept vertical by suitable guides and reciprocated
by a pitman on each side of the wheel 217 driven by a cog chain from a
chain pulley 222 driven from the chain pulley 166, the rotation being
effected at the proper moment by the clutch mechanism already
described.
