COMPLETE SPECIFICATION.
Improved Machine for Shaping and Covering Boxes or Capsules of
Cardboard and other Materials.
I, GABRIEL PATUREAU of No. 44 Rue du Poteau, Paris, France, Manufacturer,
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 construction of machine for shaping and
covering boxes or capsules of card board and other materials, the main functions
of which are the same as those of the machine described in the Specification to my
Patent No. 14252 of 1892, the construction of which for carrying out such functions
being however modified and simplified as the result of the experience I have
gained from the working of the original machine. Furthermore I have effected a
considerable improvement in substituting an automatic feed of the blanks into the
machine instead of feeding them by hand so that the whole of the operations are
now effected automatically.
The improved machine has for its object
1. To cement bands of printed paper, previously coated with gum or other
cementitious matter upon the outer surface of the boxes of cylindrical, oval or other
form.
2. To turn inwards the edges of the paper bands and cement them to the inner
surface of the box.
3. To cement a disc of paper or other material previously printed upon and
coated with cement upon the end surface of the box.
4. To stamp or shape the box, with or without providing it with a rim for
increasing its strength and improving its appearance.
5. Finishing the bottoms of the shaped boxes before they are delivered from the
machine.
In this improved machine the shaping is effected on half-boxes or capsules with
bottoms formed in one therewith, thus reducing the number of pieces of which the
complete box is composed, to three, namely, two capsules or half-boxes and a neck
piece, instead of five pieces of which hand made boxes are composed, namely, two
bottom pieces, two cylindrical pieces, and a neck piece.
Moreover, while in the band made boxes the paper covering serves both for
decoration and as means for fixing the bottom to the cylindrical part, in the boxes
made by the improved machine the paper covering only serves for decoration.
I will describe the said improved machine with reference to the accompanying
drawings in which :-

page_text: I. FEED OF THE PREVIOUSLY PRINTED AND GUMMED PAPER BAND For
CEMENTING ROUND THE BOXES, (Figs. 1, 3, 6, 24).
The paper band a which is coiled up on a drum 6 the side cheeks k of which
serve as guides, passes between rollers c and d which carry it forward to the
moistening device, in passing round a guide g and a roller e situated at the sides of
and outside the box within which the paper is to be moistened.
The forward feed of the paper band by the rollers and d is effected as
follows:-The roller d which is covered with felt, receives continuous rotary
motion, while the roller c only presses with its weight upon d so as to nip the paper
between them.
The roller d receives its motion from the shaft on which it is fixed, and which
carries a roller m bearing upon the surface of a revolving disc n so as to be rotated
thereby. The roller m can shift nearer to or farther from the centre of the disc
so as to be capable of being rotated at variable speeds thereby, being shifted for
this purpose by means of a fork o, which embraces a groove z in the boss of the
roller. This fork o can be shifted parallel to the shaft by means of a screw
spindle p on the non-threaded part of which it is fixed. The screw p is actuated
by a screw nut q that can be rotated in a support r fixed on the table 1 of the
machine.
On turning this nut the screw spindle, which is prevented from turning by the
fork o, is slid in one direction or the other, sliding with its non-threaded end in a
supports on the table 1.
As it is necessary to stop at will the forward motion of the paper band a, without
stopping the driving gear, the revolving disc n is actuated as follows:-
The boss 7 of the disc can turn freely and also slide in a hole formed in a boss of
the table 1, and a coiled spring 12 presses the disc against the roller for effecting
the rotation of the latter. For stopping this rotation, the disc n is depressed
against the action of the spring by means of a levert pivoted at u, one end v of
which has a point 2 acting on the piece 3, fixed at the centre of the disc, n, while
the other end 13 is raised by means of a cam a actuated by the handle y.
The disc n is rotated by the shaft through the medium of a feather 5 working in
a groove 4 in the socket 7 of the disc. A wheel 8 on shaft 6 gears with a worm 9
fixed on shaft 10 receiving rotary motion from the shaft 16 through wheels 11
and 15 and the endless pitch chain 14.

page_text: casing and being moistened with water therein it passes out through another
opening 24 formed in the side 22. On issuing from the casing the band a meets a
felt brush 25 fixed on a flexible arm 26, which serves to remove the excess of water
that may be on the band. A trough 27 takes up such excess of water and conveys
it to the bottom 28 of the casing f, where there is a cock for the discharge of the
water in excess. The band a then passes to the carriage through a guide
channel h.
:-
The moistening water is supplied in the form of spray to the casing fas follows
The water is led through a pipe i to a cock 29, which discharges it intermittently
into a pipe 30, from which it issues in spray, either by forming the pipe with a very
small discharge orifice, or by causing the water to impinge on a plate, or by
other suitable ineans. The cock 29 is opened intermittently at each revolution of
the shaft 10, during the time the paper baud remains in the casing f, that is, during
the time that a part of the band is being coiled round a box, such opening of the
cock being effected as follows :-On the shaft 10 is fixed a cam 31 which effects the
sudden downward motion of one of the arms, 32, of a lever pivoted at 33, and then
leaves the arm free. The other arm 34 of the lever is consequently raised and is
thereby made to lift a lever 35 pivoted at one end 36 while its other end is drawn
downwards by a weight 37 fixed to it. The lever 35 acts upon a vertically sliding
rod 38 by means of two rollers held in a slot 39. The rod 38, which is guided in
two supports 42 and 43 on the framing, has its upper end formed as a toothed
rack 44 and carries a head piece 40 against which bear stops 48 of a ratchet
device 47, the rack serving to turn the plug of the cock for opening the same, and
the head piece serving to stop the plug at a certain closing position. The rack 44
turns a pinion 41 fixed on the boss of a cam 45 having three teeth and situated
loose on the axis 46 of the plug 51 of the cock; a metal box 47 on the outer surface
of which are two diametrically opposite slopes 48 is fixed on the axis 46, and in
spaces between the teeth of the cam and the inner surface of the box, are situated
small rollers, acted upon by springs 50, so as to push them into the narrower parts
of the spaces, so that when the cam 45 is turned from the right to the left, Fig. 5,
by the upward motion of the rack, the rollers 49 will only roll round in their
spaces, without carrying the box 47 and axis of the plug with them, while when the
rack descends and carries the pinion round from the left to the right, the springs 50
will cause the rollers 49 to be nipped tight between the cam teeth and the box, and
this as also the plug 51 will be carried round thereby.
When the rod 38 rises, the head 40 in rising while the box is stationary, will
liberate the one stop 48 of the latter, so that when 38 descends by the action of the
weight 37 (which always produces a constant speed, no matter what the speed of
the machine may be) it is free to turn the cock-plug as before described, through
half a revolution, until the second stop 48 abuts against the head 40 at the end of
its down stroke.
III. AUTOMATIC FEED AND DISTRIBUTION OF THE FORMED CAPSULES Or
BOXES FROM THE HOPPER INTO THE VERTICAL SHOOT OF THE
TRANSPORTING CARRIAGE (FIGS. 1, 3, 6, 10, 11, 31, 32, 33).
The capsules are thrown promiscuously into a hopper 52, from which they are
taken by an endless chain 53 with buckets 54 which passes through it in an upward
direction, in travelling against one of the sides of the hopper (Fig. 3). The bottom
of the hopper has a rectangular opening just large enough for the chain and
buckets to pass through. As the buckets pass upward, the capsules are caught up

page_text: its axis carried by two supports 60 which are mounted loose on the shaft 10 and are
held against the hopper 52. The buckets 54 although only adapted to receive a
single capsule, might accidentally carry up two or more, and these in falling
together into the opening 56 of the shoot, might block the latter. To prevent this
the chain has a shaking motion imparted to it, which is however not sufficient to
dislodge the capsules that are properly caught in the buckets, but it shakes off any
others that are only imperfectly held.
Such shaking motion is effected by means of a double cam 61 which, in revolving
between the supports 60 and the two sides of the chain 53, alternately push against
these in an outward direction and then allow them to fall back. The cam is driven
by a pulley 62, the shaft of which receives motion from the shaft 10 through a
pulley 63 and belt 64.
The capsules require to be placed in the vertical shoot of the carriage 84 in such
manner as to present their open ends to the interior of the machine, that is to say,
towards the rotary mandril 126 so as to be fitted on to this. The capsules, on
falling from the buckets, pass on to the bottom surface 65 of the shoot 57, their
open end being directed either upward as at Fig. 31, or downward as at Fig. 32.
The first named ones are in the proper position for fulfilling the above condition,
while the second ones, not being so, must be rejected.
For this purpose the following device is employed. Near the entrance of the
shoot 57 the bottom 65 thereof has an opening 66 (Figs. 31, 32, 33) limited by the
vertical sides 69 of the shoot, the edge 68, the dove-tail projection 67, and the two
edges 70. The distance between the edge 68 and the end of the projection 67 is
such that the capsules that present their cavity upwards (Fig. 31), in sliding along,
cannot fall through the opening because in passing over the opening their forward
side 75 will have passed onto the edge 68 before the centre of gravity has passed
beyond the edge of the projection 67, so that these capsules will pass on to the
vertical shoot.
The inverted capsules at Figure 32 on the other hand in arriving with their front
edge 75 beyond the projection 67, and thus losing their support, will fall through
the hole 66, and, owing to the forward motion imparted to them, they will
successively assume the positions 55' 55 55¹¹. For receiving these capsules a
chamber 71 is provided below the opening 66, and from this chamber a shoot 74
leads back to the hopper 52, into which the said capsules are consequently
discharged. It will be seen that the capsules, in falling through the opening 66,
turn half round over the projection 67, so as eventually to occupy the position 551,
and the chamber 71, must consequently be sufficiently large to allow of this, the
end 72 being carried sufficiently far back to admit of the dotted position 55" being
assumed.
The capsules in the correct position pass from the shoot 57 into recesses o o on
the periphery of a revolving disc 76, which delivers them into the shoot 83 of the
transporting carriage 84; such delivery only takes place every time the shoot 83
arrives under the disc 76, that is to say, at the completion of each backward
motion of the carriage. For preventing the capsules from falling from the recess
before the shoot 83 is in position, one of the sides of the shoot 57 is extended at 79.
The rotation of the disc 76 is effected by means of an eccentric 82 fixed on the
shaft 10 and connected by its rod 81 to the disc 76. For preventing too many
capsules from accumulating in the shoot 57, a regulating device is provided,
consisting of a branch shoot 77, branching off from 57 at a certain height above
the lower end, so that when this is filled with capsules up to the level of the
branch, any following capsules will pass away through the latter, the shoot 57
being beut slightly to one side at 78, so that the uppermost capsule in occupying
the shifted position shewn relatively to the upper part of the shoot will facilitate
the passage of the next capsule over the rounded edge 85 into the branch shoot
while if the lower end of the shoot 57 is not filled, the descending capsules will pass
into this rather than into the branch. From the shoot 77 the capsules fall into a
convenient receptacle.

page_text: IV. MOULDing the Capsules or BOXES AND MOUNTING THE SAME ON
THE REVOLVING MANDRIL (FIGS. 1, 3, 6, 14, 15, 16, 17).
The capsules having been delivered into the shoot 83 of the carriage 84, they are
delivered thence at 88 as the carriage 84 deposits the lowermost one on to the
mandril 126, this being effected at each complete rotation of the shaft 16 which
actuates the carriage 84 by means of the cam 89 fixed thereon. The carriage has
semi circular grippers 90 and 91 of which 90 has an appendix 92. The capsule
falling to the position 88 is stopped by the appendix 92 of 90 which closes the
front of the opening 88, and the grippers 90 91 being moved backward at this
time, the capsule is held at its lower part by an extension 94 of 92. The capsule
being now in the opening 88 the carriage 84 advances towards the mandril, while
at the same time the grippers 90, 91 advance and the appendix 92 recedes, thereby
leaving the opening in front of the capsule free; the grippers 90 91 now seize the
capsule and in exerting pressure thereon impart to it the necessary circular form
for fitting on to the mandril. The carriage 84 meantime advances so as to place
the capsule on the revolving mandril 126, and at once recedes again to receive.
another capsule from the disc 76, the grippers are withdrawn and the appendix is
replaced in its first position, while at the same time the piston 93 bears against the
capsule during the time that the paper band a is being cemented on the capsule.
When this is completed the piston is withdrawn at the same time that the capsule
is pushed off the mandril, and the piston having resumed its original position
another capsule passes to the opening 88. The piston in bearing against the
capsule while the paper band is being cemented on, has rotary motion imparted to
it at the same speed as the mandril; for this purpose its head 95 alone is made
moveable, at the end of a rod 96 to which it is attached. This rod has a groove 97
into which passes a pin 98 thereby fixing the head 95 to the body of the piston
while allowing it to rotate. The piston 93 and its moveable head 95 are fixed in
the tube 99 fixed to a rod 100 which actuates it. The several parts above
described are actuated as follows:-The carriage 84 is moved to and fro by the
cam 89 by means of the arm 101, at the end of which is a roller 102 engaging
in a groove of the cam. The piston 93 is actuated by the cam 103, fixed on
shaft 16, by means of the arm 104, the roller 105 of which engages with the
groove of the cam, the arm 104 being fixed under the carriage 106 to which the
rod 100 is attached.
The to and fro motion of the grippers is effected as follows:-Two columns 107
fixed on the table 1 hold the cross piece 108 on which is fixed the vertical axis of
a roller 109 which can be adjusted by a thumb screw nut 110. On the cylindrical
part 111 of the carriage 84 is mounted a revolvable cylinder 112 on the surface of
which is a helical groove 113 into which takes the roller 109, so that by the to and
fro motion of the carriage 84, a to and fro rotary motion is imparted to the
cylinder 112. To this are fixed ears 114 having eccentric arc-shaped slots 115 in
which are engaged rollers 116 the axes of which are fitted to sliding plates 117 to
which are attached the grippers 90 91 by means of rods 118 which serve as guides
to the grippers and sliding plates.
The stems 118 are for this purpose passed through slots 119 in the pièce 120
connected to the carriage by distance pieces that allow of the passage of the
slides 117; the stems 118 also pass through slots 121 formed in the piece 122
fixed to the plate 120 by distance pieces 123. The shoot 83 is also fitted to this
piece 122. By the rotation of the cylinder 112 the eccentric slots 115 will cause
the rollers 116, and the parts to which they are attached, and consequently also
the grippers, to move towards and away from the opening 88.
A plate 124 having a circular opening for the capsule to pass through, is fitted
in front of the grippers by means of distance pieces 125 fixed to the plate 122.

page_text: V. FORWARD FEED OF THE MOISTENED PAPER STRIP TO THE MANDRIL
FOR COILING IT ROUND AND CEMENTING IT TO THE CAPSULE
(FIGURE 1, 3, 4, 6, 14, 19, 20, 21, 22, 23, 27, 28, 38, 39).
The capsule being held on the mandril 126 by the piston 95 while the mandril
revolves, the band a passes from the passage h on to the metal bar 127 forming a
fixed table, independent of the cementing carriage 128; on the table 127 the
band a meets a roller 129 beneath which it passes this rolier having the double
object of guiding it and of holding it on the table while allowing it to slide
thereon when drawn forward by the carriage 128. This roller which prevents the
band a from moving backwards, is situated at the end of a lever 130 pivoted to a
support 131, the two arms of which are fixed on the opposite sides of the passage h.
The band a, after passing under the roller 129 passes to the point where it is to be
cut by the scissors at 132.
The table 127 has a rectangular opening allowing a second inner table 133,
fixed to the carriage 128 to travel so as, by means of fingers 134, to seize and
carry with it at intervals the paper band a. The paper band having been cut
at 132 by the scissors, the fingers 134 are raised to allow the carriage 128 and
table 133 to recede without carrying the band backwards. At the moment when
the carriage 128 has moved backward to a certain extent, the fingers 134 fall and
seize the band a between them and the moving table 133; the carriage 128 then
advances to the same extent to which it before moved backwards, and which is
requisite for enabling the band to be seized between the roller 135, which has been
lowered, and the mandril. At this moment the roller 135, is raised and causes the
end of the moistened paper band to be pressed against the capsule on the mandril,
so as to adhere thereto. The fingers 134 are at the same time raised for allowing
the paper to be drawn forward by the rotating mandril to the extent necessary for
entirely covering the capsule (Fig. 38). While such coiling is being effected, the.
roller 135, being raised, presses the band against the capsule.
The capsule being covered with the paper band, this now has to be cut, which
operation will be described in the next section; after the cutting, the roller 135
and the fingers 134 are lowered, and the carriage moves back again. As soon as
the band begins to be cemented to the capsule, it requires to have its one edge, .
turned over on to the end surface of the latter (Fig. 39).
This is effected as follows:-
(Figs. 27, 28.) A. circular brush 136 with vertical axis receives continuous rotary
motion, and is moved towards the mandril so as to bear against the edge of the
capsule and thus bend down the projecting edge of the band. In order to prevent
the brush from rubbing against the tube 99 surrounding the piston 95 that bears against
and turns with the mandril, an opening is formed in the tube. Motion is imparted
to the above mechanisms as follows:-
The continuous rotary motion of the mandril 126 is effected by means of the
wheels 139 and 140 (Fige. 6, 8, 9, 14) the first of which is fixed on the sleeve 141
on which the mandril is fixed, while the second 140 is fixed on the shaft 16 which is
driven from the main shaft 20 through gearing 17 18 and 19. The movements of
the carriage are effected as follows:-The to and fro movement is effected by the
toothed sector 142 gearing with the toothed rack 143 fixed underneath the bottom 144
of the carriage 128. In this to and fro motion the carriage is guided by two lugs 145
on its underside 144 sliding against the sides of guide 146, fixed on the table 1,
and to prevent any raising of the base 144 during such motion, it carries four
rollers 147 that roll against the upper part of two longitudinal guides 148 fixed at
the sides of the slide 146. The toothed sectors, 142, are fixed on the lever 149
pivoted at 150 to a support 151 fixed under the table 1 of the machine, the lever 149
receiving its motion from the rod 152 pivoted thereto, and connected to a revolving

page_text: crank 153. The connection of the rod 152 to the crank is effected by means
of a bolt that cau slide in a groove 154 formed in the crank, this arrangement
serving to enable the extent of motion of the toothed sectors 142 to be varied as
may be required.
The crank 153 is driven by the shaft 155 on which it is fixed and which receives
its motion from a rod 156, one end of which, provided with a roller, is actuated by
the groove 158 of a cam 157 through the medium of disc 159, loose on the shaft 155,
and the bolt 160 which secures this disc to the disc 161 fixed on the shaft 155. The
rod 156 is guided by two rollers 162 and 163 the axes of which are fixed on the
arm of the support 151. The bolt 160 is fixed on the disc 159 and can. slide in a
circular slot in the disc 161, for enabling the position of the carriage 128 at the end
of its movements to be adjusted.
A spring 192 exerts a constant forward pull on the lever 149. The position of
the carriage at the end of its forward motion is also insured by the following device.
On the base 144 of the carriage is fixed a stop 164 which at each forward motion
comes against the end of a screw 165, the nut of which is formed by a vertical
extension 166 of a table 167 fixed on the two longitudinal guides 148, the screw
being also provided with a lock nut.
The metal table 127 bears with its one end upon a vertical arm 168 of the
carriage 128, its other end being fixed on a support 169, moveable in a dove-tail
groove; the support is adjusted by means of a screw 170 turning in a vertical
arm 171 of the table 167 and screwing into the support.
This arrangement has for its object to allow of the adjustment of the direction
of the band a so that it shall always arrive at the mandril in a position at right
angles to the vertical plaue, passing through the axis of rotation; by this means
the band in being wrapped round the capsule is prevented from assuming a helical
direction.
The fingers 134 are raised by the following means, at the moment of the return of
the carriage 128. They are fixed on a blade 172 which is attached to the arm
pivoted at 174, between the two branches 175 of a support formed by the
carriage.
To this arm 173 are connected two vertical rods 176 having rollers that are.
supported as are also the arms 173 and the fingers, by two moveable guides 177, one
end of which rests on the end of a screw 178 while the other end is raised by two
arms 179 fixed on the same shaft 180 which is turned by means of the lever 181
fixed thereon.
This lever 181 has a roller at its end which is actuated by the cam 182 fixed
on the shaft 16. Two springs 183 with variable tension, bearing upon a rail 184
fixed on the carriage 128 serve to press the fingers 134 upon the metal
table 133 when they are not raised by the guides 177 or by the device to be
presently described.
The pressing roller 135 is raised against the mandril as follows:-It is mounted
between the arms 185 of a support moveably mounted on an axis 186 fixed on the
carriage 128. The two arms of this support are connected below by the transverse
piece 187 on which act the heads of two screws 188 carried by a piece 189 in which
is fixed a rod 190 guided in the table 1; this rod 190 is provided at its lower end
with a roller acted upon by a cam 191.
When this cam does not raise the support and roller 135, these parts fall back
by gravity. The fingers 134 are also raised by the following means for allowing
the paper band to pass when it is being drawn forward for coiling round the capsule.
On one of the vertical rods 176 is fixed a small arm 193 in which a threaded hole
receives a screw 194 the end of which is towards one of the arms of support 185, so
that when this is raised, the screw 194 as also the arm 193 and consequently the
arm 173 and the fingers 134 fixed thereto, are also raised during the whole time that
the coiling on of the paper band lasts.
The rotation of the brush 136 and its lateral movement are effected as follows
(Figs. 6, 14, 27, 28). A cam 195 fixed on the shaft 16 moves the end of

page_text: a lever 196 having a roller 197, and the lever pivoted on the fixed vertical shaft 198,
communicates its motion to the toothed sector 199 fixed on it.
The toothed sector 199 (Fig. 27) gears with a pinion 200 fixed on the vertical
shaft 201 which in turning moves the arm 202 on which are fixed the supports 203
of the brush. The arm 202 is connected to the shaft 201 as follows:-On 201 is
fixed a worm wheel 204 gearing with a worm 205 the bearings of which are fixed on
the underside of the arm 202, this arrangement having the object to enable the
position of the brush 136 to be adjusted. By turning the worm 205 by means of the
button 206 the worm is made to travel more or less round the wheel 204, and thereby
moves the arm 202 to which it is attached. A. spring 208 fixed on the support 207
presses the roller 197 continuously against the cam 195.
The rotation of the brush is effected by means of the toothed wheel 2 19 fixed on
the sleeve 141 and gearing with the pinion 210 fixed on shaft 211 turning in bearings
on the fixed support 212 on the bracket 213 supporting the vertical shaft 201. The
shaft 211 carries a bevil pinion 214 which transmits its rotary motion to the brush 136
by means of the bevil gear 215, 216, 217, shaft 218, and bevil gear 219, 220, the last
named pinion being fixed on the shaft 221 carrying the brush. The wheels 215, 216,
are fixed together and run loose on an extension of the shaft 201, which also serves
as bearing to the shaft 218.
VI. CUTTING THE PART OF
THE PAPER BAND COILED ROUND THE
CAPSULE (FIGS. 6, 14, 25, 26).
When the length of paper band a necessary for coiling round a capsule has
passed to the extremity 132 of the table 127 (which corresponds to the complete
convolution less the distance of the axis of the mandril from the end of the table,
the scissors, pivoted on a support 222 which can move to and fro at right angles to
the direction of motion of the paper band, advance and cut the latter, advancing also
in the direction of the band, so as to effect a square cut. These movements are
effected as follows:-
The motion is imparted to the support 222 by means of the cam 223 fixed on the
shaft 16 and acting on a roller at the end of a lever 224 turning loose on an axis 225
and on the boss of which is fixed another lever 226 actuating a roller 227 situated
in a slot thereof and turning on the end of a boss 228 situated under the slide of
the support of the carriage 222.
The blades of the scissors are actuated as follows:-
The lower blade 230 is stationary in cutting and is fixed on a sleeve 232; only
the upper blade 229 moves up and down against the lower blade. For this purpose
the blade 229 is fixed on the axis 231 which also passes through an eye of the lower
blade and the sleeve 232. On this axis is fixed a lever 233 on the end of which
bears the lever 234 pivoted at 235 under the table 1; this lever is actuated at its
lower end by a cam 236 on shaft 16. The upper end of 234 is connected to a
spring 237 which insures the contact of its lower end with the cam 236.
For opening the scissors after each cutting operation there is provided a
counteracting spring 238 on a small rod 239 fixed to the sleeve 240 of the carriage
which spring bears against the free end of the lever 233 and thereby causes the
axis 231 to turn and open the scissors by lifting the upper blade.
The extent of such motion is limited by a screw stop 241 fixed in a small
stem 242 on sleeve 240.
The forward movement of the scissors during the cutting, at the same speed as
the paper, is effected as follows.
The sleeve 232 on which is fixed the lower blade 230 of the scissors, can slide in
the outer sleeve 240 of the support 222, and on this outer sleeve is formed a neck
into which takes a loose ring 279. A coiled spring 243 fitted upon the axis 231
and bearing on the one hand against the lever 233 and on the other hand on the
sleeve 240 continuously presses the blade 229 against the blade 230 and consequently
causes the collar 244 of the sleeve 232 to bear against the sleeve 240.
B

page_text: J
The ring 279 has on its underside an appendix 245 passing under the sleeve 240
and having a helical or oblique groove 246 which causes a roller 247 carried by the
sleeve 232 to slide in a groove formed in the sleeve 240 parallel to the axis thereof.
To the ring 279 is also fixed an arm 248 which is acted upon by the head of the
lever 234.
From this arrangement it will be seen that when this lever moves the arm 248
acted upon by a spring 249 (Fig. 14), the ring and consequently the oblique
groove 246 will turn, and will shift the roller 249 in its groove, as also the
sleeve 232 to which it is fixed. This sleeve will consequently push forward the two
blades of the scissors at the same speed as the paper band, and as it is the same
lever 234 that operates for cutting and for advancing the scissors, the cutting of
the band a will be always effected at right angles to the travel thereof.
VII. FORWARD FEED OF THE PAPER BAND, PREVIOUSLY COATED WITH
CEMENT FROM WHICH A DISC IS TO BE CUT FOR CEMENTING ON THE
END SURFACE OF THE CAPSULE (FIGS. 2, 7, 8, 9, 10).
The paper band 250 (Fig. 7) from which the discs are to be cut, is coiled on a
roller 251 between side cheeks and passes between two rollers 252, 253, which draw
it intermittently forward to the cutting device which will be described in the
subsequent operation; the cutting being effected, the band 250 passes on to a guide
roller 254 which conveys it through a channel to the outside of the machine.
The feed of the band by the rollers 252, 253 is effected as follows. The lower
roller 253 the circumference of which corresponds to the length of paper required
for each cutting operation, alone receives rotary motion, the upper roller 252 being
merely carried round by contact. The roller 253 is rotated by the shaft 255 ou
which it is fixed and which is driven by gearing from the shaft 258; this shaft
receives intermittent rotary motion from the wheel 259 on shaft 260 through
wheels 261, 262, 263; the mechanism for imparting the intermittent motion to the
shaft 260 and wheel 259 will be presently described. The roller 254 which carries
the band away after the discs have been cut, is driven from a pulley on 253 through
grooved pullies 264 and 265 fixed respectively on shafts 255 and the shaft of
roller 254, and the belt 266 passing over guide pullies 267. A brake 268 controls
the movement of the reel 251, and a channel 269 guides the paper before passing
between the rollers 252, 253.
VIII. CUTTING THE DISC OF PAPER AND CONVEYING THE SAME INTO
THE RECESS OF THE PRESSING DISC SITUATED BELOW IT (FIGS. 2, 7,
8, 9, 10).
On passing from the rollers 252, 253, the paper band 250 passes on to a circular
matrix 270 fixed under the cylinder 273 into which passes a hollow cutting punch 272
formed in one with a hollow piston 271; this piston is guided in the cylinder 273
fixed under bracket 274 attached to the framing 1. The discs of paper, when cut,
remain within the punch 272 and have to be pushed out of it; for this purpose a
second piston 275 within 271 descends together with the latter and continues its

page_text: at its other end to a support 287. This lever 286 is in its turn actuated by the
cam 288 in the path of which works a roller mounted on the lever at 289. The
cam is fixed on the main shaft 20 of the machine.
The piston 275 is actuated as follows; it has at its upper end a cylindrical
rod 290 which is actuated by the lever 291 on which it is screwed; this lever is
fixed to the end of a rod 292 (Fig. 9) which moves in a hollow column 293 which
serves as guide and is fixed to the frame 284. The rod 292 is actuated by the
end 294 of a lever 295 pivoted at its other end to a support 296; this lever 295 is
actuated by a cam 297 (Fig. 10) fixed on the main shaft 20, in the path of which
is a roller carried by the lever 298.
The hollow piston 277 (Fig. 2) is actuated as follows. It works in a hollow
column 299 which serves as its guide and which is fixed by means of a foot to the
framing 284. The piston 277 is actuated by the end 300 of a lever 301 (Fig. 2)
pivoted at its other end to the support 302; this lever 301 is actuated by the
cam 303 fixed on the main shaft 20 and having a path in which is situated a roller
pivoted to the lever at 304.
IX. EXPULSION OF THE CAPSULE OR BOX FROM THE MANDRIL AFTER
GUMMING ON THE PAPER BAND, AND CONVEYING THE SAME INTO THE
RECESS OF THE PRESSING DISC WHICH CONTAINS THE CUT DISC OF
PAPER (FIGS. 1, 2, 3, 6, 8, 14, 39).
As has before been described in IV and V, the capsule or box is held on the
revolving mandril 126 by the piston 95 while the paper band is being cemented on;
for then removing the capsule from the mandril, the latter, which is hollow,
contains a piston 305 which, during the gumming on of the band on the capsule,
is kept in a backward position by means of a spring 306 which causes it to bear
with a collar 307 against the rear end of the mandril. This spring 306 bears at
one end against the sleeve 141 and at the other end against the ring 308 fixed on
the piston 305. For removing the capsule, the piston 305 is made to advance
beyond the mandril while the piston 95 recedes to the same extent.
These two pistons thus holding the capsule between them bring the same over
a shoot 309, when they both suddenly recede (the piston 305 being withdrawn by
the spring 306) and the capsule being thus liberated falls into the shoot 309 so
formed as to prevent it from turning. In order to prevent a capsule from adhering
to the piston 305 and not falling, the following arrangement is provided.
Surrounding the piston 305 within the mandril is a sleeve 310, which a spring 311
bearing against the ring 307 tends to push beyond the piston; a pin 312 passing
through 305 holds the sleeve 310 back and limits its motion beyond the piston,
the pin being made to work in two opposite slots in the sleeve. Thus when the
piston 95 presses the capsule on to the mandril the sleeve 310 is Hush with
the extremity of the piston 305, the spring 311 being compressed, but when the
pistons 305 and 95 suddenly retire, the spring 311, being no longer compressed,
expands in acting upon the sleeve which consequently pushes the capsule off the
piston.
The shoot 309 (Figs. 1 and 2) has a rapid inclination whereby the capsule is
directed onto the piston 277 in the recess 278 of the disc 276. At this moment
the piston 277 is in the position described in the VIIIth section; that is to say,
about half way up the cylindrical part of the recess, while the piston 275 is raised
to the level of the underside of the matrix 270 so as to allow the capsule to enter
the recess 278.
When the capsule arrives on the piston 277, on which is a cut disc of paper, the
upper piston 275 descends and adjusts the capsule upon the piston 277, which has
descended to the level of the lower end of the cylindrical part of the recess; the
piston 275 then rises slightly for allowing the turning over of the upper edge of the
paper band to be effected (Fig. 40). The several parts above described ate

page_text: operated as follows. The actuation of the pistons 275 and 277 has been described
in VIII, and that of piston 95 in IV.
0
The piston 305 is moved forward for removing the capsule by means of the one
end of the lever 313 pivoted at 314 in a support under the table 1, the other end
of the lever being actuated by the cam 315 fixed on the shaft 16.
X. FOLDING AND GUMMING THE PAPER BAND WITHIN THE CAPSULE AND
PRELIMINARY CEMENTING ON OF THE OUTER DISC (FIGS. 2, 8, 9, 10, 29,
30, 40, 41).
The capsule contained in the recess of disc 276 as described in Section IX, has
the projecting upper edge of the paper band turned over into it by the following
means.
Four horizontal sector plates 316 (Figs. 29, 30) are made to advance within the
disc 276 in a direction radial to the centre of the capsule, thereby bending the
paper edge over the edge of the capsule (Fig. 40), the plates being withdrawn in
the first instance into such a position as to allow the capsule to enter the recess.
The disc 276 is made in two parts as shewn to facilitate the construction.
When the paper edge has been turned over as described, the piston 275, which
has at its lower end a block of caoutchouc 317 (which, when not subjected to
pressure, is of the same diameter as the interior of the capsule) is lowered, while
at the same time the sector plates 316 are rapidly withdrawn, so that the caoutchouc
block in descending, will press down the edge of the paper which has been turned
down, and will apply the same to the inner surface of the capsule (Fig. 41).
The block 317 in descending still farther bears against the inner bottom surface
of the capsule so as to press the outer surface upon the coated face of the
paper disc 318 and as the lower piston 277 is heated, the cement will soften so as
to cause the paper disc to adhere to the capsule.
In thus pressing upon the bottom of the capsule the caoutchouc block 317 will
increase in diameter and will consequently press the sides of the capsule against
the surface of the recess, so as to cause the outer paper covering to adbere more
firmly thereto.
The sectors 316 are actuated as follows for operating as above described. The
sectors, which slide in a circular recess 319 in the disc 276, are provided with
>tems 320 which slide radially in grooves in the disc, and are connected to toothed
racks 321 by means of distance pieces 322, which racks slide in grooves 323 formed
between the two parts of which the dis: 276 is composed; these grooves are
extended and open out at the outer end to allow of the passage of the distance
pieces 322. Four pinions 324 situated in cavities in the disc 276, and whose
vertical axes 325 are held between the two parts of which 276 is formed gear with
the racks 321 so as to actuate them, these pinions being actuated by a toothed
ring 326 which revolves in a groove formed in the upper part of 276.
This toothed ring 326 receives an intermittent reciprocating rotary motion from
the rod 327 pivoted thereto by means of the pin 328 which works in a segmental
groove in the lower part of 276. The rod 327 is actuated by the lever 329 pivoted
thereto and fixed on a vertical shaft 330 carried in a step bearing on the frame 284
and in a bearing under the table 1. On this shaft is also fixed another lever 333
which imparts thereto its reciprocating motion, being actuated by the cam 334
fixed on the shaft 20 in the groove of which cam is a roller pivoted to the
lever 333 at 335.
For heating the piston 277 the following arrangement, among others, may be
employed. Within the piston 277 is a cylindrical hollow 336 within which opens
a tube 337 communicating by a hole formed at right angles through the piston
with a flexible pipe connected by a union 339, through which steam is admitted.
The piston head 277 is thus heated by the steam, the resulting condensed water
being led off through the conduit 340, formed in the thickness of the side of the
cavity.

page_text: water to wherever required.
The flexible tubes are provided to allow of the vertical motion of the piston;
the hollow column 299 is provided with an opening for the passage of the union
pieces 339 and 341.
XI. CONVEYANCE OF THE CAPSULE TO THE STAMPING AND SHAPING
DEVICE (FIGS. 2, 8, 9, 10, 18).
The capsule after being operated upon as described in the recess 278 of the
disc 276, passes thence into the recess 343 of the revolving disc 344 which at this
moment is situated exactly underneath it. For this purpose the two pistons 275
and 277 descend simultaneously, with the capsule between them, which they place
so that it is situated in the cylindrical part of the recess 343 and they then retire
in opposite directions. The disc 344 which was stationary for receiving the
capsule, is then rotated for bringing it to the stamping device which operates in
the said recess when this has been brought beneath them. The axis of the
stamping device is situated in a vertical plane passing through the axis of the
shaft 20. For enabling the disc to turn, the two pistons 275 and 277 must be
withdrawn from the recess 343, this being effected at the exact moment when the
capsule is situated in the disc 344. For this purpose the piston 275 rises suddenly
and resumes the position which it had before the 7th operation, that is to say, it is
situated above the matrix 270; the piston 277 continues to descend until it is clear
of the underside of the disc 344. For bringing the capsule to the stamping device,
this disc receives an intermittent rotary motion in the following manner :-
The disc is held on a hollow vertical shaft 345 between the collar 346 and a
spring washer 348 which is pressed down by a screw ring 347 so as to hold the-
disc firmly but allowing of a slight elasticity in the vertical direction when requisite,
the disc 344 being prevented from shifting round by studs on 346 entering recesses
in the disc 344.
The shaft 345 receives rotary motion through the toothed wheel 349 fixed
thereto by bolts, and gearing with a wheel 259 fixed on the upper part of a
shaft 260 guided in a hollow column 352, and carried in a step bearing 355 on the
frame 284.
On the lower part of this shaft 260 is fixed another toothed wheel 353 gearing.
with the vertical wheel 354 on the horizontal shaft 356 which is carried in a
bearing 357 on the framing 284, and in a socket fixed in the column 299. On the
shaft 356 is fixed a toothed wheel 359 which receives intermittent rotary motion
from a toothed sector 360 (Figs. 9. 10.) fixed on the main shaft 20, which receives.
continuous rotary motion through the pulley 361 thereon. The intermittent rotary
motion imparted by the shaft 20 to the disc 344 through the above gearing has
the object of bringing successively each recess underneath the disc 276 and in line
with the stamping device, and the momentary stoppage of the disc 344 has for its
object to allow the capsules to pass from the disc 276 into the recesses 343 and to
allow the stamping to be effected.
For affording the disc 344 a perfectly fixed and stable position during the time
it is stationary, the following arrangements are employed.
In order to insure that the wheel 359 shall at each revolution of shaft 20, turn
to exactly the same extent under the action of the section 360, a locking device is
employed consisting in a ring 362, fixed to the wheel 359 on the outer circum-
ference of which are formed arc shaped notches 363 (Fig. 9) the centres of which
coincide with the point of intersection of the vertical plane of the ring and the
centre of the axis of the shaft 20.
On the sector 360 and shaft 20 is fixed a circular path 364 having the same
radius and centre as the notches 363 and projecting from the ring 365 fixed on 20;
this circular path has a gap corresponding in length and position to the length of
the toothed sector 360 (Fig. 9) so that when the sector is about to leave the.

page_text: toothed wheel 29, the circular path 504 begins to engage with the are of th
notch 363 which will at that moment be presented to it, and will thus prevent.
the wheel 359 and consequently the disc 344 from rotating during the whole time
that the path 364 is so engaged, that is, until 363 is liberated by the gap of the
path, at which moment the sector will again gear with the wheel 359 and will turn
it and the disc 344 through another division.
In order that each recess 343 may always come exactly opposite the stamping
device at the end of each such before described movement of 344, and also exactly
below the recess 278 of the disc 276, there is provided between each two
recesses 343 a notch 366 in the edge of the disc, one of the edges of which is
considerably rounded off at the lower side for facilitating the entrance of a locking
bolt 367 (Fig. 18) into the same. This bolt 367 consists of a prismatic piece
having a tooth 368 which in rising enters the notches, the prism being guided in a
support 369 fixed to one of the uprights 370 of the frame for the stamping device,
and actuated by a rod 371 pivoted thereto which is also pivoted to the end of a
lever 372 actuated by a cam 375 on shaft 20, the lever being pivoted to a
bracket 373 on the upright 370. The lever is acted upon by a spring 374 which
tends to draw it and the locking bolt upward, so as to lock 344 when 372 is not
depressed by the cam.
XII. STAMPING THE CAPSULE OR Box FOR FORMING A RIM THEREON,
WHEN REQUIRED, AND FOR FINALLY CEMENTING THE DISC OF PAPER
THEREON (FIGS. 2, 8, 9, 10, 18, 34, 35, 36, 37).
The capsules or boxes are brought by the intermittent rotation of the disc 344
between the stamping devices Fig. 34 consisting of two pistons, the upper one 376
of which is hollow and has a rod 377 passing through it and carrying a head 382
situated in a cavity of the piston, and in this head is fixed a cylindrical caoutchouc
block 379; the lower piston 378 is hollow and heated internally.
At the moment when the disc 344 is stopped, with a recess situated between the
pistons, the lower one rises to near the underside of the disc 344 (Fig. 35) leaving
a space between the two. At the same time the piston 376 descends with the rod
and plunger 379, and fits accurately into the conical seat of the recess 343, while
the caoutchouc plunger entirely fills the capsule and bears against the bottom
thereof so as to press the outer surface, on which the paper disc is partially
cemented, against the upper face 380 of the lower piston 378.
The upper piston and plunger now remain stationary while the lower piston 378
rises (Fig. 36) whereby, the caoutchouc plunger being spread laterally by such
pressure, the lower part of the sides of the capsule which projects below the
disc 344 will be bulged outward in a corresponding mauner, thus forming the
commencement of a rim 381 on the capsule.
The rod 377 now rises slightly (Fig. 37) so as to cause the plunger to be
withdrawn from the bottom of the capsule, whereupon by the continued upward
movement of the piston 378, the rim 381 is finally formed by the pressure of the
face 380 against the underside of the disc 344.
It is to be understood that the capsule may have a different form of rim formed
thereon, and also, that when not required, the formation of the rim may be entirely
omitted.
At the same time that the above operation is being effected, the paper disc,
being pressed upon by the heated piston 378, is finally cemented on to the bottom
of the capsule by the softening of the cement with which the face next the capsule
is coated.
The stamping being completed, the two pistons 376 and 378 retire so as to
allow the disc 344 to turn and bring another capsule opposite the stamping devices.
The several movements of the above described devices are effected as follows:
The lower piston 378 is screwed into a sliding piece 383 guided in grooves
formed in the uprights 370. The lower extension 384 of this piece is forked and

page_text: carries a roller 385 which bears upon a cam 386 on the shaft 20. By screwing the
stem of the piston 378 up or down in the piece 383, its position can be accurately
regulated, a lock nut 387 being provided for securing it when adjusted.
The piston may be heated internally in any convenient manner; in the
arrangement shewn, a central passage 388 in its stem contains a steam pipe 389
communicating with the outside by means of a passage 390 formed in the upper
part of a piece 391 fixed to the piston stem and contained in a recess in the sliding
piece 383, the tube 389 being formed in one with the branch 390.
The opening 390 is connected by a union 394 to a flexible steam supply pipe.
The water of condensation passes from the piston into a cavity 392 of 391 whence
it is discharged through a passage 393 to which a flexible pipe is attached.
The upper piston 376 is screwed with its stem into the sliding piece 395 guided
between the uprights 370 so that the position of the piston can be accurately
adjusted; it is secured by a lock nut 396.
The piece 395 is connected to the lower piece 397 (Fig. 18) also guided by the
uprights 370, by means of two rods 398 which slide freely through holes in 383.
On its upper side the piece 397 has two slots 399 and 400 in which are mounted
two rollers 401, 402, that bear against a double cam 403 on shaft 20 which cam is
thus made to move the pieces 397 and 395 downwards. The upward motion of
these parts is effected by micans of the lever 404 pivoted at 405 to a bracket under
the framing 284, and carrying at its free end a weight 406.
The rod 377 passing into piston 376 is actuated by an arm 407 to which it is
connected by means of two screw nuts 468. The arm 407 is actuated by means of
a rod 409 fixed thereto and which slides through bosses 410 formed on 395
and 383 and carries at its lower end a roller 413 acted upon by a cam 412 on
shaft 20 which presses the rod upwards. The downward pressure of the rod 409
and consequently of the plunger 379 carried thereby, is effected by disc spring 414,
bearing at bottom on a shoulder on rod 409 and at top on the underside of 410.
For limiting and regulating the upward motion of the plunger 379 (Fig. 37) the
rod 377 is made to butt at the end of its upward motion against a stop 415 with
spring 416, the tension of which is regulated by the piece 417 screwed into a
bridge piece 418 fixed to 395.
XIII. FINISHING THE BOTTOMS OF THE SHAPED CAPSULES OR BOXES
(FIGS. 2, 8, 9, 10).
When the stamping of the capsule, or box is completed, the finishing thereof is
effected as follows. In the space between each recess of the disc 344 and the
hollow shaft 345 is formed a radial slot 419, in line with the recess. In each of
these slots is a slide 420 fixed under a support 421, which slides on the disc 344.
Beneath this slide is fixed a plate 422 sliding on the underface of the disc.
In the supports 421 are mounted vertically sliding pistons 423 guided by
rods 424. The carriage thus formed by the parts 421, 422, and 420 moves at one
time towards the centre of the disc 344 and at another time towards the recess 343
thereof. While the recess passes below the recess 278 of the disc 276, and during
the stamping, and for the final expulsion, the said carriage moves towards the
central shaft, while during the 13th operation, which occurs between the stamping
and the final expulsion the carriage moves towards the recess 343. During the
first described motion the pistons 423 are raised, and during the second motion
they are lowered so as to rest upon the plates 422 in passing through the recesses.
Consequently, when the stamping is completed, the carriage corresponding to
the recess in which is situated the capsule that has been stamped advances
towards the recess and the piston 423 presses the bottom of the capsule against
the beated plate 422 during the whole of the subsequent operation. This
pressure
upon the bottom of the capsule during a certain length of time is sufficient for
rendering it level and smooth, that is, for "finishing" it. The plates 422 are
supported at the end of their forward stroke by means of notched lugs 437 fixed

page_text: under the disc 344, with which their front edge engages during the time that the
pistons bear upon them. In place of the plates 422 other supports, or pistons
such as 423, may be employed beneath the disc 344.
The supports 421 as also the devices attached thereto and which revolve with
the disc 344, are moved to and from the central axis by means of the fixed cain 425,
in the path 426 of which are rollers 427 carried by an arm of the supports 421.
The raising and lowering of the pistons 423 for pressing upon the capsules is
obtained as follows:-The raising is effected by a cam path 428 and the lowering
by a path 429, these paths being both formed on fixed cam plates 430, the one on
the upper side and the other on the underside. On these cam paths runs the
roller 431 carried on a pin 432 fixed on the rod 424, the support 421 having
guiding slots 433 for allowing the passage thereof. For obtaining an elastic
pressure of the pistons 423 on the bottoms of the capsules there is provided a
spring between the pins 432 and a shoulder on the rod 424. The rollers 431 pass
alternately from the upper cam surface to the lower one and conversely, each part
of the cam plate 428 being made to extend partly over the other part, at
diametrically opposite points as shewn at Figs. 9 and 10, in order to guide the
rollers from the upper to the under path, and conversely. The cams 425 and 430
are fixed round a fixed sleeve 434 surrounding the vertical shaft 345, and carried
by a bridge piece 435 forming part of a transverse bearer 436.
The plates 422 require to be heated for finishing the capsules; this may be
effected by way of example, by conduction from the disc 344 which is heated by
the hollow shaft 345 on which it is fixed, steam being admitted into the shaft at
the upper end through a pipe 451 while from the lower end the water of
condensation is discharged through lateral openings 441.
The shaft is supported at its lower end in a step-bearing 438, the base 439 of
which is carried by three columns 440, this arrangement being employed for
allowing the passage of the shaft 20 with space for the cams fixed thereon.
The condensation-water passes from the shaft into an annular channel 442 in
the bearing, whence it flows off through a passage 443.
The bearing 438 is provided with a stuffing box to prevent escape of steam.
The upper end of shaft 345 also works in a stuffing box 444 formed in the
transverse bearer 436 and in the cap of which the steam pipe is fixed. The
bearer 436 is fixed on the one hand to the cross head 446 of the upright 370 and
on other hand to a colump 447 the lower end of which is forked at 449 so as to
fit over the bearing 448 of shaft 20, to the base of which bearing the column is
fixed by feet 450 secured by screw bolts.
XIV. EXPULSION
OF
THE FINISHED CAPSULE OR
(FIGS. 2, 8, 9, 10, 18).
Box
The expulsion of the capsules after the finishing described in the previous
section is effected when the recess containing the same stops underneath the
piston 453 (Fig. 10). This piston consists of a tube sliding in a support 454 fixed
on the outer surface of the sleeve 434; it is widened out at the lower end which
acts on the capsule so as only to bear upon the edges thereof, and not on the
bottom, for expelling it. This piston is actuated by means of a rod 455 pivoted
to the disc 456 fixed in the tube as near as possible to its lower end, the rod being
pivoted at its upper end to a lever 457 which is pivoted at its other end to the
