page_text: contrary direction. y" are small springs that tend to press the rollers y' forward,
and in thus preventing looseness cause them to bite, directly is turned in the
direction of the arrow.
Owing to the form of the cam 11 shewn at Fig. 1, it will be seen that the shaft E
and consequently the feed rollers g G will receive a feed motion twice in every
revolution of shaft H, whereby the band A' is made to advance firstly to an extent
necessary for causing it to be grasped by the carriage K, and secondly to the
extent corresponding to the length required to cover the box.
Over roller g passes an endless felt band stretched over a second roller g' and
which serves to take up any excess of paste that may be carried along by the
band A' as it passes over 9. Any excess of paste that may be taken up by the
upper roller G (which bears with its weight on the band A' and is carried round
by frictional contact) is scraped off the same by a scraper i on an arm j.
On passing from between the feed rollers G. g, the paper band A' passes on to
a felt apron h, which is stretched between the brackets 12 and 13.
Although I prefer the above described arrangement of intermittent feed for the
band A¹, yet the machine may also be made to operate with a continuous feed of
the band, the rollers G. 9 being in that case made to revolve continuously.
III. FEED TOWARDS THE MANDRIL OF THE BOXES TO BE COVERED.
The boxes to be shaped and covered are placed by hand in a vertical shoot M
Figs. 4, 11 and 12 fixed on a sliding carriage N, from which shoot they issue one
by one at m as the preceding one is placed by the feed mechanism of N on to the
mandril O, such feed taking place at every rotation of shaft H. The carriage N
is actuated by the cam n on this shaft.
IV. SHAPING AND FEEDING THE BOXES ON TO THE MANDril.
The carriage N has claws 20 and 22 Fig. 12 which are of semicircular form.
The box descending at m is stopped by the appendage 21 of the claw 20, which
closes the opening m while the claws are withdrawn. When the claws are advanced
towards the box, the appendage 21 is withdrawn and the box passing between the
claws is gripped thereby, so as to receive from them the exact circular shape.
The carriage N advances, and the box, being propelled forward by the piston 23 as
will be presently explained, it is placed upon the mandril while this is rotating.
The carriage N then retires, the claws move apart, and the appendage resumes
its previous position for the following operation. Meanwhile the piston 23 is kept
applied against the end surface of the box on the mandril until this box has become
covered by the paper strip A', after which the piston quickly returns and resumes
its position within the cylinder p'. The piston 23 revolves with the mandril O as
it is mounted on the end of a rod 24 having a neck 25 which is held in the piece 26
by a pin. The whole is carried by a tube p which receives motion from a rod
and cam as will be presently explained.
For imparting to the carriage N its to and fro movement it has a downward
extending arm 27 engaging with a roller in a cam groove n on shaft H.
The piston 23 receives its motion from a cam r on H by means of a bracket N¹
with arm 28, to which bracket the before mentioned rod q is fixed.
The movements of the claws are imparted by the following means.
Two standards fixed on the table Q carry rigidly the piece t. Upon t is pivoted
a roller 29 which is secured to t by means of a screw and thumb nut for regulating
the rotation of 29. On the cylindrical part pl of the carriage N is a cam groove 30
with which the roller 29 engages so that thereby a partial rotation is imparted to
the cylindrical part pl at the same time that it is moved forward and backwards by
the cam n.
In consequence of this rotation of p¹ the slotted pieces 31 formed in
one with p¹ and provided with eccentric circular slots 32 are also made to turn.
With the slots 32 engage rollers 33 fixed to the pieces 34 which slide in the
pieces 35 forming part of that portion of N which does not receive rotary motion.

page_text: To 34 are fixed rods 36 which slide in a rectangular opening formed in 37 on
which is fixed the shoot M. The claws are pivoted to 37 which is carried by
supports 38. In consequence of the eccentricity of the slots 32 and of the rotation
of p¹ the rollers 33, as also the parts 34 and 36, and the claws, recede from or
approach the centre of the opening m.
V. SEIZURE OF THE END OF THE PAPER BAND AND BRINGING OF SUCH
END TO THE MANDRIL FOR ROLLING IT UPON THE BOX.
The box being kept securely upon the mandril O by the piston 23 the mandril
receives a continuous rotary motion from the shaft H by means of toothed
gearing U and V, which latter is mounted upon an extension X of the mandril.
The paper band, on passing from the apron, is led under roller 14 and between
the pressing roller 15 and the fixed metal table 18, which is separate from the
carriage K. The band A¹ is then drawn forward at intervals by the rollers 39
and 40, shown more clearly in Figs. 17 to 19. The roller 15 has for its object
to prevent the paper band from moving backwards when the carriage K travels
backwards for seizing the paper band A', and it also serves as a brake when
the paper is drawn forward by the rollers 39 and 40. The roller 15 is carried at
the end of a lever 16, the other end of which is kept in a raised position by means
of a support 17 fixed to the carriage K for allowing the band A' to pass. This
band being situated on the table 18 and having been cut by the shears L upon the
carriage K and being situated near the shears, between the table 18 and an open
covering plate 19 at the end of 18, the upper roller 39 is raised in order to allow
the carriage K to recede without carrying back the paper band A. The
carriage K recedes in order afterwards to advance the requisite distance for
causing the paper band to be seized between the mandril O and the roller 41.
Before such advance the upper roller 39 is lowered for seizing the band between
it and. the lower roller 40. The band being seized, the carriage K advances the
necessary distance for causing the band to engage between the mandril O and
the roller 41.
In order to enable the rollers 39 and 40 to draw along the paper now between
them, that is to say in order to prevent them from revolving when the carriage
advances, they are provided with ratchet teeth and pawls 44, which allow the
rollers to rotate when the carriage recedes but which hold them stationary when 39
is lowered on to the band, so that the latter is then firmly nipped between the
rollers and is drawn forward as the carriage advances. When the carriage has
advanced so that the roller 41 is situated under the mandril, this roller is raised so
as to press the end of the paper band against the box on the mandril, thus causing
it to adhere to the latter by means of the paste thereon and, as the mandril and
box rotate, the said roller 41, in pressing the paper band against the box, causes it
to adhere thereto as it is rolled upon it. As soon as the paper band commences to
be rolled upon the box, the projecting edge thereof is bent over and applied to
the bottom of the box so as to adhere thereto by the following means.
A circular brush 42 mounted on a vertical axis 93 (see Fig. 13) receives a
continuous rotary motion. The brush moves to one side for allowing the box to
be placed on the mandril and then presses against the bottom of the box so as,
by its rotation, to cause the paper band, which is being wound upon the box
to be bent over on to the bottom and to adhere thereto by means of the paste.
In order that the brush may not bear against and be worn out by the tube p
which surrounds the piston 23 a suitable hole is formed in the tube.
In the event of a paper band not adhering properly to the box the coiling of
such band round the pressing roller 41 is prevented by combining with the latter a
small roller 43 round which and round 41 pass three endless silk threads, whereby
such detached band is directed away from 41. The movements of the carriage
and the several rollers are effected by the following means.
The motion of the carriage K is effected by the groove 45 formed on the cam 46

page_text: by the medium of the roller 47 (Fig. 1 and Figs. 11 & 14) on the rod 48 which
slides between rollers 49 and 50 and is connected to a crank plate 51 loose on the
shaft 52 but connected to disc 53 fixed on 52 by means of a screw bolt 54 fixed
to 51, which passes through a slot formed in 53, so that the adjustment between 51
and 53 enables the position of the carriage K to be adjusted. The motion imparted
to disc 53 effects the partial rotation of shaft 52 and crank arm 55 to which is
connected one end of a rod 56 whose other end is connected to a lever 57 pivoted
at 58 and imparting motion to the toothed sector 59, which gears with a toothed
rack 60 fixed on the under side of the carriage K. A spring draws the tail of
the lever 57 backwards. The carriage is guided in its motion by means of guide
rollers. The roller 39 is raised in the following manner.
It is mounted on an arm 62 pivoted at 63 and having two vertical arms 64
carrying rollers which come in contact with two movable rails 65 of which the
end 65 rests upon a point while the end 65" is lifted by the arms 66 fixed on one
and the same shaft 67 which receives a partial rotation by means of the lever 68,
also fixed thereon. This lever has a roller in contact with a cam 69 fixed on the
shaft H, whereby the said motion is imparted to the shaft 67. The springs 69¹
tend to keep 39 in contact with 40. The pressing roller 41 is raised as follows.
It is mounted on an arm 70 pivoted at 71. This arm carries ou its under side
two projections 72 on which acts the rod 73 having a roller which is acted upon
by a cam 74, so that by this means 70, and consequently 41, are raised. The
arm 70 falls by gravity when the cam 69 no longer presses it upwards.
The brush 42 receives its rotary motion and its motion to and from the box on
the mandril as follows. A. cam 75 fixed on H imparts an angular motion to the
arm 76 provided with a roller. This arm 76 is fixed on an axis 77 and imparts
thereto a corresponding partial rotation. On this axis is fixed a toothed sector 78
which gears with a pinion 79 fixed on axis 80. On this axis is fixed the arm 81
on which is mounted the brush 42, so that, by means of the cam 75, the brush
receives its motion to and from the box. The continuous rotary motion of the
brush is effected by means of the toothed wheel 82 fixed on the piece X of the
mandril. This wheel 82 gears with a pinion 83 fixed on a spindle 84 which imparts
motion to bevil wheels 85, 86, 88 and 89, the latter being fixed on spindle 90, the
motion of which is imparted by bevil wheels 91 and 92 to the spindle 93 on which
is mounted the brush 42. The bevil wheels 86 and 88 are mounted loose on a
pin 87 forming an extension of the spindle 80, so that the angular displacement
of 81 and 90 can be effected without interfering with the rotation of the brush.
The spring 80' fixed upon 80 keeps the roller of the arm 76 pressed continuously
against the cam 75.
VI. CUTTING OF THE PORTION OF THE PAPER BAND COILED AND PASTED
UPON THE CAPSULE.
When a length of paper band sufficient for coiling round the box has passed
beyond the extremity 19 of the fixed table, the shears L pivoted to a support 94
fixed to the carriage K cut the band A' while accompanying it in its forward
motion, this being effected in order to ensure a cut at right angles to the band.
The shears are actuated as follows.
A lever 95 is acted upon at one end by a cam 96 and at the other end a spring 97
acts thereon in the contrary direction for always keeping 95 in contact with 96.
This lever bears upon an arm 98 which is fixed rigidly to the upper movable blade
of the shears, the lower blade of which is fixed. By the action of the cam on
the lever 98 the upper blade is moved down so as to close the shears and cut the
band A¹.

page_text: the box requires to be removed from the mandril. For this purpose the mandril O
is hollow and contains within it a piston 99 which is held inwards by a spring 100
so as to be flush with the face of the mandril when the box is upon it. When the
pasting of the paper band is completed, the cam 101 acts on lever 102 which
forces forward the piston and thus forces the box off the mandril and causes it to
fall into the jointed shoot 103. The piston is prevented from rotating by means
of a groove formed therein and a screw which engages with such groove. In
order to cause the box to fall upon its bottom a small flap 104, situated within the
mandril face, is hinged to the latter at bottom and is acted upon by a spring 105
situated behind it, so that when the piston 23 recedes from the box as before
described the upper end of the flap being pressed outwards by its spring bears
against the upper part of the box, and, in turning it downwards, causes the box
to fall on its bottom. The shoot 103 is pivoted at 106 and is acted upon by means
of a cam 107 and a guided rod 108 so as, by a slight up and down motion, to ensure
the downward sliding of the box. The box then slides into the enclosed shoot 109
which directs it into one of the sockets 110.
When the box does not properly place itself in the socket 110 it remains in the
shoot 109. For preventing the momentary stoppage of the machine or the
accumulation of boxes in the shoot, the bottom 111 of the latter is movable upon
an axis 112 and a spring 113 keeps it in position. After each passage of a box
the part 111 is lowered by means of a finger 114 fixed thereto which is pushed
against by the arm 115 fixed to the piston 116. If the box has been properly
placed in the socket nothing happens, but if it remains on 111 this in being
lowered causes the box to fall down to the outside and thus a socket remains
empty.
For allowing the box to place itself suitably on the shoot when it is expelled
from the mandril, that is to say for giving it time to turn round so as to bring
its bottom horizontal, it is necessary that the carriage K shall not advance too
quickly. It is necessary therefore to diminish the speed of the shaft Has it is not
possible to stop its motion altogether. For effecting such reduction of speed, a
shaft H carries a toothed pinion 117 which gears with a toothed wheel 1171 fixed
on shaft H¹
On this shaft are fixed wheels 118 and 119 which gear respectively
with 121 and 120, which are fixed on shaft H to which the before mentioned
varying speed requires to be given. For this purpose the motion is at one time
imparted from 118 and 121 for the quicker speed, and at another time from 119
and 120 for the slower speed. The wheels 118 and 121 impart the quick speed
to H during nearly a complete revolution with the exception of the arc 122, Fig. 15,
not provided with teeth. At this moment, that is to say during the arc 126, 128,
the wheel 119 acts upon the wheel 120.
Assuming now that a box has just been expelled from the mandril, then wheel 118
gears with 121, the teeth 123 of the wheel 118 gearing with the teeth 124 of
wheel 121. Shaft H then revolves with maximum speed until the last tooth 125 of
wheel. 121 escapes the last tooth of 118, so that these are now out of gear, and at
this moment shaft H' continuing to turn the tooth 127 of wheel 119 comes into gear
with the tooth 126 of 120, whereupon, the ratio between the gearing is changed,
causing the speed of shaft H to be diminished until the last tooth 128 of wheel 120
leaves the wheel 119. At the moment when this last tooth 128 moves out of gear
with tooth 131 of 119 the tooth 123 again gears with 124 in order to again
accelerate the speed. There would then take place a wedging action of 129 and 128
as 131 drives, and the ratio between the two pairs of wheels is not the same.
order to avoid this I have removed the tooth intermediate between 130 and 131 and
I have pivoted the tooth 129. Thus at the moment that 123 gears with 124 and
when 131 still engages with 128, the latter pushes the tooth 129, which can thus be
displaced owing to the space left by the removed tooth and the movement is then
smoothly transmitted through 118 and 121. The spring 132 brings tooth 129 back
into its original position.
In

page_text: VIII. TURNING OVER THE UPPER EDGE OF THE PAPER BAND AND
PASTING IT ON THE INSIDE OF THE BOX.
The box having been delivered by the shoot into the conical part 133 of the
socket 110, Fig. the piston 116 is lowered by lever 167 and pushes the box into
the bottom of the socket 110 on to the piston 134 which is made to descend at the
same time by lever 172. As soon as this is done the tables 135 and 136 turn.
The table 135 has as many orifices or sockets as the table 136, the former having
only for its object to guide the boxes by the conical form of its openings. It is
connected to 136 by distance pieces e' placed between each socket. The tables
receive a step by step motion equal to the distance from one socket to another at
each revolution of the shaft H₁, whereby a box after having fallen into a socket
receives four movements before it is acted upon by the piston 137 and four after
this action takes place. The box is carried by the lower table underneath the
caoutchouc piston 137 (Figs. 9 & 9A) and the turning over devices fixed in the
plate 138. These devices are constituted by four sectors 139 which pass between
the two tables 135 and 136 and which move away for allowing the passage of the
depressing piston 137. The turning over and pasting of the upper edge of the
paper band then takes place as follows. The box being in position, the sectors 139
advance towards the centre of the socket and thus thereby turn the edge of the
paper over the upper edge of the box into a horizontal position. The piston 137
then descends and at the moment when it would touch the sectors, these quickly
retire, so that the paper edge has no time to rise again. The piston 137 continues
its motion and being of a diameter corresponding to that of the interior of the box,
forces the paper edge against the sides of the latter so as to make it adhere thereto.
The paper being turned over and pasted down, the piston 137 rises, and for
preventing the box or the paper edge from rising with the piston the sectors again
approach closely to the piston without touching it, thus retaining the box in the
socket. The piston 137 having risen, the tables 135 and 136 move one step for
bringing the next box underneath the same.
The various motions of the different devices for the above purpose are as
follow :
The piston receives its motion from a forked lever 140 fixed on a shaft 141
which receives its motion from the lever 142 actuated by the cam 143 fixed on the
shaft H. The lower table 136 is moved by means of the cam 144 fixed on H'.
This cam acts on the lever 145 which is continuously drawn back by the spring 146
fixed to the part 147. The latter is pivoted on a vertical axis 148 and carries a
pawl 149, which, when the lever 145 causes the part 147 to turn round the axis 148,
causes the advance of one tooth at each revolution of H' of a ratchet wheel 150
fixed to the table 136 which rotates on the axis 151.
In order that the sockets of the tables shall always be brought accurately
opposite the piston 116 and of the depressing piston, a stop 152 is provided, which
is made to bear against the notches 153 formed between each of the sockets.
When the plate 136 turns the stop 152 is raised owing to the rounded form of the
notches, and when the following notch of the table passes in front of the stop this
falls in again and holds the table which receives no further motion from the
cam 144.
The devices for pressing inwards the edge of the paper are actnated as follows.
The four sectors 139 are fixed to the pieces 154, Figs. 54 9 and 10.
These pieces
are themselves fixed to toothed racks 155 which slide in grooves formed between
two plates 156 and 157. These grooves are extended downwards for leaving room
for the passage of the pieces 154. Four pinions 158 are fixed between the two
plates 156 and 157 gearing with the toothed racks 155, these pinions also gearing
with a toothed crown 159 turning freely in the upper plate 156. This toothed
crown is rotated by the spindle 164 connected thereto by a crauk arm 165, rod 161
and pin 160 (Figs. 4 and 9) which spindle is acted upon by a lever 163, thereby

page_text: .
imparting motion to the toothed crown, the pinions, the toothed racks and the
sectors fixed to the latter. The cam 162 imparts an angular motion to the lever 163
which is fixed to spindle 164. This spindle in turning acts on 165 fixed thereto and
also on 161 (the lever 163 is always kept in contact with the cam 162 by means of
the spring 176). The piston 116 is always pressed by a spring 166 contained in a
tube. This piston is lifted for allowing the boxes to fall into the sockets by means
of the lever 167 fixed on the hollow shaft 168 and on this shaft is fixed another
lever 169 actuated by the cam 170 fixed on H¹. The lower piston 134 is
continuously drawn downwards by the spring 171 and it is raised by means of the
lever 172 fixed on the shaft 173 which passes through 168 and is independent
thereof. On 173 is fixed the lever 174 which is actuated by the cam 175.
IX. EXPULSION OF THE BOX AFTER TURNING IN THE PAPER EDGE AND
BRINGING THE SAME TO THE STAMPING APPARATUS.
The box with its finished paper covering is carried forward by the table the distance
of one socket at cach revolution of the shaft H. When each socket arrives under-
neath the piston 177 the box contained therein is forced thereby into a socket of
the table 183 which serves to conduct it to the stamping device. The piston 177 is
actuated by a lever 178 pivoted to the support 180. This lever is raised or lowered
by a support 182 which is connected to the lever at 179 and this support is fixed on
the slide 181 which serves for the stamping, and which receives a vertical motion.
The box is afterwards brought to the stamping device and is subjected to the
stamping operation in the table 183 when the socket arrives at a point diametrically
opposite that at which the boxes are fed in.
For carrying the boxes forward the table 183 receives rotary motion from a
shaft 184. This shaft receives its motion from the gearing 185, which receives it
from the table 135 which is provided with teeth; but as there is always a certain
amount of play between the teeth of the gearing each socket of the table 183 would
not come accurately opposite the stamping device. To ensure such accurate
position the motion is imparted also by a friction cone combined with a safety
catch. The cone 186 loose on 184 receives its motion from 188, 189, 190, 191,
192, 193, from 194, and lastly from H". This conc 186 gears with 187 fixed
upon 184, and when the catch 195 holds the plate 183 the cone 186 turns on the
cone 187 without carrying round the shaft 184.
The locking of the table is effected as follows:
Between each socket of the table 183 is formed a notch 196 having a very
rounded edge at bottom (Fig. 8) for facilitating the entrance of the catch 195.
This catch is formed by a prism 195 which is bent so as to enter the notches of the
table and thus stop its motion. It is guided by a support 197 fixed to one of the
uprights 198 of the framing of the machine and is actuated by a spring 199 fixed to
the lever 200 pivoted at 201, Fig. 8. This lever 200 is fixed to the rod 202 which
is itself fixed to the catch.
In order that the catch 195 may allow the table to turn, a cam 203 fixed on the
shaft bears against the lever 200 and thus draws the catch out of the
notch 196.
✗. STAMPING THE BOX FOR OBTAINING THE RIM.
The box having been placed in the table 183 (Figs. 1, 4, 8 23, 24 and 25) in the
position indicated, the stamping is effected as follows.
The piston 204 rises and enters into the lower cone of the socket leaving a certain
amount of play. At this moment the piston only serves to support the bottom of
the box. The piston 205 with its caoutchouc pad descends and enters the upper
cone of the socket without play, and as the piston is formed at the end with a
cylindrical block of caoutchouc 206 this caoutchouc will entirely fill the interior o
the box and will oblige it to assume the form of the socket in which is formed a

page_text: hollow rim 207 (Fig. 24). By this means a rim is roughly formed. The caoutchouc 206
then recedes slightly and the piston 204 is forced up into the upper cone, whereby
the bottom of the box is forced up and is made to assume exactly the configuration
of the hollow rim of the socket (Fig. 25). The caoutchouc at this moment bears
upon the bottom of the box without entering the rim. The stamping is thus
completed and the pistons recede for allowing the table 183 to turn.
The various motions are effected as follows.
The piston 204 is screwed into a sliding piece 208 in order to allow of its
adjustment for wear. The piece 208 slides in uprights 198 of the framing and is
actuated by the cam 209 fixed on H and which acts on the roller 210. The
piston 205 is also screwed into a sliding piece 181. This piston is hollow and
within the same is a stem 211 to which is fixed the caoutchouc piece 206. This
stem 211 can slide within the piston and is screwed to a lever 212, and the pressure
of the caoutchouc can also be adjusted by means of the screw 213 which presses the
spring 214 against the stem 211. The screw 213 and the spring 214 bear upon the
cap 215 of the framing. The lever 212 receives its motion from the rod 216 and
the cam 217 and has for its object to raise the caoutchouc 206 at the time of the
second pressure.
A "Belleville" spring 218 imparts the necessary pressure to
the caoutchouc. The sliding piece 181 is lowered as follows.
It is connected to the piece 219 by means of two rods 220, and the piece 219
is moved downwards by the cam 221. Two helical springs 222 maintain separate
the pieces 181 and 208 which are made to approach by the cams. For preventing
the table 183 from rising when the last pressure of the piston 204 takes place,
there are provided two guides 223 situated 10 m.m. from the table and adjustable
at will being formed of screws turning in supports 224 fixed to the uprights 198.
XI. FINAL EXPULSION OF THE BOX COMPLETELY FORMED.
The expulsion of the box is effected at the moment when each socket of the
table 183 passes beneath the piston 225. This piston is formed of a tube 225
which slides in a support 226.fixed to the support 227 of the vertical shaft 184 of
the table 183. This piston is hollowed at the extremity which acts on the box
for expelling the same in order that it may only bear upon the thickness of the
edge of the box and not upon the bottom. It receives its motion from the rod 228
pivoted to the base 229, which rod receives its motion from the lever 230 fixed
to 178. The expelled boxes fall into a shoot 231, Fig. 8.
Figs. 20 and 21 show a modification of the feeding apparatus for the paper band
having for its object to replace the felt band f which is impregnated with paste
and which consequently has to be renewed. In place of such felt band a flat belt
of caoutchouc 232 is provided which receives motion in consequence of the rotation
of the roller g. This belt passes round a second roller which is turned in
consequence of the motion imparted to it by the belt 232. The paste given off by
the band A upon 232 is removed by the brush 233 which turns in a pan of
water 234. The paste is removed from the brush by means of a scraper 235.
This brush receives its motion from the shaft H" by means of the wheel 236 and
the pitch chain 237 passing round the pitch wheel 238 fixed on the axis 239 of the
brush 233. A second brush 240 which acts upon a considerable length of the
belt 232 dries this by means of the frictional contact, the brush being made to
travel at a considerable speed in the contrary direction to the belt 232. This
speed is obtained by the two rollers 241 and 242 round which the endless brush
surface 240 travels, the roller 241 receiving motion from the shaft 239 by means
of the pitch wheels 243 and 245 and the endless pitch chain 244.
Figs. 26 to 32 shew the box during the various stages of the before described
operation. Fig. 26 shews the box as delivered on to the mandril O; Fig. 27

I wish it to be understood that having already obtained a Patent No. 20520
of 1890 for a machine for covering boxes with paper in which are certain
mechanisms similar to some of the mechanisms described in the foregoing Specifi-
cation, I do not now claim such mechanisms otherwise than in combination with
those other parts of the above described machine which are new, but
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
In machinery for shaping boxes and covering them with paper.
1. The herein described mechanism for coating the two paper bands with
cementitious matter, for fixing the two bands one upon the other, and for feeding
the same forward.
2. The herein described mechanism for supplying definite lengths of the paper
band to the boxes to be covered.
3. The herein described mechanism for feeding the boxes forward to the
revolving mandril.
4. The herein described mechanism for shaping the boxes and placing them on
to the mandril and holding them while the paper is being coiled thereon.
5. The herein described mechanism for effecting the coiling of the paper band
on to the mandril and for turning over the bottom edge thereof and pasting it on
to the bottom of the box.
6. The herein described mechanism for expelling the covered boxes from the
mandril, and feeding the same to the mechanism for turning in the upper edge of
the paper band.
7. The herein described mechanism for turning the upper edge of the paper
band into the interior of the box and pasting it on to the sides thereof.
8. The herein described mechanism for finally stamping the boxes for imparting
to them the requisite shape.
9. The construction of machinery for shaping boxes and covering them with
paper, combined and operating substantially as herein described with reference to
the accompanying drawings.
