Referring to the drawings:
A designates the frame of the machine and B designates a counter shaft
horizontally thereon, and carrying a cam with which engages a lever 2, which is
supported on the frame A, and connected by a rod 2×, with a lever 2**, provided
with a pawl 3, which latter meshes with a ratchet-4, on the vertical shaft 5, to
which the pasting table or rotary dise C is secured (as shown in Fig. 1).

page_text: Sustained above the table C, is a paste-distributer D, which consists of a plate 6,
arranged vertically in the guides 7, which are supported on the frame A, and
shaft 5, (see Figures 1 and 2). To the horizontal upper limb of the guides 7 are
fitted screws 8, which pass through the upper limb of the plate 6, and by means of
nuts 7, and springs 7**, said plate may be vertically adjusted, so as to regulate
the quantity of paste distributed on the table, it being noticed that the paste is
primarily placed on the table, and as the latter is rotated by the ratchet 4, pawl 3,
rod 2*, levers 2 and 2×× cam 1, and shaft B, the required quantity of paste is
carried under the bottom of the plate 6, and thereby nicely and uniformly spread
upon the table C.
Over said table pass paper pasters and carriers E, which consist of horizontal
plates or frames 9, which are secured by arms to the vertical shaft 10, the latter
being mounted on the frame A.
Adjacent to the table C is a table 11, for holding a pile or number of sheets of
paper, and adjacent to said table 11 is a table 12. The table 11 has upwardly-
extending fingers 50 between which a package of blanks is held and it is supported
upon a spring so as to move downwardly under the pressure of a paster and carrier-
arm E and return to its original position as such pressure is removed; (as shown in
Fig. 47), a supporting-rod 51 passes down through bearings in a plate 54 and in a
portion 56* of the frame, a spring 57 being secured between said frame and a
collar 58 on the rod; the plate 54 is adjustable vertically, a supporting-rod passing
through a bearing 55 as shown and a set-screw 56 holding it at the desired
height. 52, 52 are guide-arms secured to table 11 and passing through bearings in
plate 54.
Supported on an arm attached to frame A, is a matrix Ex, which is of the form
of a three-sided tube, open at both ends and one side, and having preferably flanged
tables or wings 14 which are rigidly connected with the walls of the matrix at the
open side thereof; (see Figures 1, 5, 9 and 10).
F designates a mould or form which is secured to the frame of the machine, and
so located that it may be embraced by the matrix.
The matrix E is arranged so that it will lie in a horizontal position with its
wings 14 parallel to the tables C, 11 and 12 to receive a sheet of paper it is then
turned up so as to assume a substantially vertical position parallel to the former F
and then moved toward said former so as to enclose it thus folding the paper into
a U form around the mould F and after the paper has been further acted upon to
form it into a tube the matrix is returned to its horizontal position to receive
another sheet; these motions in the plan shown in the drawings are accomplished
by the devices below described. The matrix, I may here note, is made adjustable
in size by means of a plate 24×× and adjusting screws 24*** and the former or
mould F is given any desired size by being made in two parts and provided with
adjusting screws 60 (see Fig. 47); the adjustable bottom is not essential as the
matrix will operate even if its bottom never comes against the former; the outer
face of the mould is recessed or grooved as shown at 61 (Figs. 43, 9 and 10) so
that the pasted portion of the blank will not come in contact with the mould as the
tube is removed from it. I will also here note that as shown the matrix is longer
than the mould and to give passage to the side flaps formed in the blank in forming
a bottom upon it, triangular openings 59 are formed through the sides of the matrix
(as shown in Fig. 47); these are only necessary when the elongated matrix is
used where the matrix does not extend below the mould they could not of course
exist.
Secured to the side of the matrix is a crank 15, to which is pivoted a pitman 10,
the lower end of the latter being pivoted to a lever 17, which is engaged by a
cam 13 whose shaft 19 is mounted on the frame A (see Figures 5 and 6). It will
be seen that when the cam rotates, motion is imparted to the lever 17, pitman 16,
and crank 15, whereby the matrix is turned from the horizontal position shown in
Figures 4, 5 and 6, to the vertical position shown in Figures 8, 9 and 10, said

page_text: natrix after accomplishing its purpose, again returning to a horizontal position, as
will be hereinafter more fully explained.
When the matrix is in vertical position, it is advanced to and from the mould F,
by means of an arm 20, which is pivoted to the frame A, and has secured to it:
above its axis an arm 21, carrying a roller 22, which engages with a cam 23 on the
shaft 19, it being seen that the rotation of the cam 23 operates the arms 21 and 20,
so as to move the matrix forward and backward, the positions of the matrix in
relation to the mould being shown in Figures 9 and 10.
The sides of the matrix may be slotted, as at 24, to receive the folding blades G,
(see Figures 10, 12 and 13) said blades, which fold the ends of the blank around
the back of the mould, being connected with arms 25 to which motions are imparted
by means of links 26, and levers 27, the latter having their axis on the frame A,
and engaged by canis 28, whose shafts 29 are mounted on said frame A. Occupying
a portion of the slots are rollers 24× (see Figure 10) to prevent injury to the paper-
when the matrix passes over the mould. The slots 24 are not essential as the
folders may pass in front of the matrix.
The paper pasters and carriers EE are arranged to rotate and move vertically
intermittently. Thus, one of them being above the paste table C, is moved down
into contact therewith and rising carries with it paste from said table; it is then
revolved till it comes over the paper table 11 then again moved down till it passes
on the top sheet and rising carries said sheet with it: the paper sticking to the
pasted surface; it is again revolved till it comes over table 12 which is opposite
the paste table C and again moves down against said table thus, as it were, taking
a fresh hold on the sheet of paper and also where two or more carriers E are used
balancing the pressures on the carrier frame as a whole moving up again the
carrier is revolved to a position over the horizontally-lying matrix Ex upon which
or the wings of which it presses the sheet on its next vertical downward movement.
While the carrier is pressed down on the matrix a paper-holding device. H having.
dependent fingers (see Fig. 4) arranged to pass through spaces in and about the
carrier E, is pressed down on the paper and holds it down while the carrier rises
preparatory to its next rotative movement, the said holder next rises having the
blank on the wings or table of the matrix.
To give the carrier-arms E the described motions they should be secured to a.
support arranged to rotate and move vertically and actuating mechanism must be
provided to give the said motions at proper times; as shown, the carriers are
secured to a shaft 10 which is journaled in the frame and to which a cam 38 (see
Figs. 4 and 5) gives vertical movement through lever 39 which, as shown, engages
the top of the shaft by rolls 41, 41 which enter between collars 42 42 secured
thereon a spring may be arranged as shown at the bottom of the shaft to sustain
its weight and decrease the strain on the cam. The intermittent rotation of the.
carriers is accomplished by a reciprocating lever 46 one end of which is secured to
a sleeve 46x, which sleeve is suspended from the frame and concentric with the
shaft 10 which it surrounds; this sleeve and lever are capable of an oscillatory
movement but are vertically stationary; their movement is derived from a cam 49
acting through lever 48 and connecting-rod 47. Depending from lever 46 is a
lug or finger 45 and secured to the carrier support (shaft 10) is a plate 43 having
notches or perforations 44 formed in it so as to come in turn beneath the finger 45
and equal in number to the intermittent rotative movements required. The
mechanism is arranged so that after each downward movement of the carriers the
following upward movement will cause one of the slots 44 to engage the finger 45,
the lever 46 then makes a partial revolution turning the carriers to their next
position and they are then again depressed, the lever moving back to its original.
position ready to engage the next notch as the carriers again rise. In order to
prevent rotary movement of the carriers during their vertical movements, I provide
a holding device arranged to lock the carriers from rotation before they are released
from engagement with the reciprocating finger 45 and keep them locked until again

page_text: engaged by said finger as shown; this locking device consists of a plate 63 having
perforations in it corresponding to those in plate 43, said plate 63 being secured to
the frame and the shaft 10 passing through it; and to act with said plate I provide
pins 64 secured to shaft 10 as shown at 65. It will be seen that as the carriers
inove down the pins 64 will enter the perforations in plate 63 and lock the shaft
against rotation as the disc 43 is moving down and before the slot 44 has cleared
the pin 45 so also the pins 64 will retain their engagement until the pin 45 again
engages a slot in dise 43. The reciprocating pin 45 may be guided in any con-
venient way as well as by the lever 46, and of course the locking pins could be
attached to the frame and the plate to the shaft instead of being attached as shown;
these are mere obvious mechanical expedients.
The holder H used to detach the blank is attached to an arm 30 guided on:
shaft 10 and by a connecting-rod 32 moving in guide 33, said. rod receiving its
motion from cam 36 through lever 35 and link 34.
The sheet of paper is formed into a tube by the matrix over the mould, as has..
been stated, and the advancing of the folding blades G (see Figure 10). after which
the bottom of the tube requires closing. This is accomplished as follows:
Referring to Figure 14, 66 represents a table on which is supported a slide or
tucking-blade 67 which is moved to and fro by means of a link 68 and lever 69,
the latter being engaged by a cam 70 on the shaft 71, the slide being so located as
to move under the matrix, so as to fold down on the mould one side of the paper
tube, this operation being shown as commenced in Figure 14. The angular folders 72
now advance within the partly folded bottom of the tube and are rotated out-
ward so as to form the sides of the tube out and, as shown, through the openings 59;
said folders 72, which rotate in reverse directions, being of the form of flat blades"
and connected with toothed shafts 73 which mesh with double rack bars 74 which
extend at a right angle to the shafts 73 and are operated by a link 75, a lever 76,
and cam 77, and cam-shalt 77* (see Figures 14, 15, 16 and 18) said lever and cam.
being properly. mounted on the frame of the machine, it being noted that the
toothed-shafts 73 are journaled on a slide 78 which is parallel with the slide 67 and
operated by a link 79, a lever. 80, and a cam 70× similar to the cam 70 on the
shaft 71 (see Fig. 15). The folding blade 85 then moves in folding.down the back
flap of the bottom upon the front flap, the sides of the blank being folded into
triangular form over the folders 72, (blade 85 is actuated, see Figures 8, 14, 28
and 29, by an arm 86 pivoted to arm 20 below its axis and operated by a
link 87, lever 88, and cam 89 on shaft 19). The triangular. side Haps are then
pasted, as shown, by the fingers 81 (see Figs. 17 and 19) which fingers dip into
cups 82 (see Figs. 4 and 17) said cups being secured to rod 20 so as to move
therewith, the fingers 81 being pivoted to arm 20 and raised and lowered by
arm 82%, lever 83, and cam 84. The folders 72 then revolve inwardly turning the
pasted triangular flaps down upon the front and back laps of the bag bottom, the
blade 85 being drawn back just before the flaps are completely folded down and
the plunger or presser-plate 96 rising and clamping the bottom against the..
plunger, 90. The bag at this stage is directly over the pocket 95 of a tabic J
(see Figs. 1-14 and 50), and which will be hereinafter more fully described.
:
The plunger 90 is located within or at the bottom of the mould F (see Figs. 14,
19, 21 and 22) and rises and falls by means of a sliding bar 91, passing through the..
mould and which is fitted in guides 92 on the frame A, and connected with a
lever 93, to which motion is imparted by a cam 94 on shaft 71, said lever and the
cam-shaft being mounted on the frame A.
The plunger 96 is located, as shown in Fig. 21, below the pocket 95, and is
adapted to rise therein, and meet the bottom of the bag as formed, and press..
upwardly against the same, the bottom of the bag thus being subjected. toithe
pressing action of the two plungers in opposite directions. After the pressing.
action, both plungers are lowered, and the bottom of the bag is at or about the
level of the table J. The plunger 90 now rises clear of the pocket..

page_text: The plunger 96 is raised and lowered by a sliding bar 97, link 98, lever 99, and
cam 100, the latter mounted on the shaft 100x (as shown in Fig. 24), said lever
and the cam-shaft being mounted on the frame A.
The pocket 95 is one of a series, the others of which are designated by the same
numeral together with a cross or star, said pockets being secured together and to
a supporting device which sustains them in place above the table J and permits of
an intermittent rotation of the series. As shown in the drawings (see Fig. 42),
the pockets 95 are secured to a rotatable annulus or ring J', the said annulus or
ring having projections or teeth 102, with which engages a dog 103, to which is
pivoted a rod 104, having shoulders 105 at the ends thereof, said rod being
embraced by the arm 20, which has an opening to receive the rod (see Figs. 6
and 45); it being noticed that the arm 20 in its operation moves the rod 104, in
opposite directions, so as to withdraw and return the dog 103 from and to the
stops 102, whereby the rim is free to be rotated, and when rotated, will be stopped
at the proper time, and prevented from rotations while other operations are being
accomplished.
In Figs. 1 and 47 the rim J', has a serrated periphery 106, the teeth thereof
being engaged by a pawl 107, which is hung on a lever 108, mounted on the
axis 101 of the tube, said lever being operated by an arm 109, lever 110, and
cam 111, on one of the shafts 29, said lever being mounted on the frame A.
The pocket 95, and other pockets 95*, are secured to the rim J¹, so as to rotate
therewith (see Figs. 1, 39 and 42) the several pockets being open from top to
bottom.
To follow the operation of the machine, the bag, as has been stated, is in the
pocket 95, and is carried along by the rim J', until it arrives under the filling
chute J, (see Figs. and 30) the top of the bag being shown in Figure 30, as
projecting above the pocket 95, so that said top may be subsequently folded down
or closed when the bag is filled.
K designates a hopper which receives the supply of material to be packed.
Communicating with the hopper is a conveyor L, whose endless apron carries the
material from the hopper K to the top hopper III. Located below the latter
hopper is a box 113, having within the same a vertical plate 114, which has
swivelled to its arm 115 a nut 116, fitted on a screw 116* on a slide 116**
connected with said box, whereby said plate may be moved laterally, and thus
adjusted so as to increase or decrease the capacity of said box 113. (See
Figures 30, 31 and 34.) The box and consequently the slide, has motion imparted
to it in order to carry the contents of the box from the base 117, on which said box
rests as a bottom, over the opening 118 of a chute 119 the latter having forks or
branches at its bottom, so that there are two discharges for the material entering
said chute. (See Figure 34.) Motion is imparted to the box by means of a
link 120* rock-shaft 121, and an arm 122, the latter engaging with a cam on the
shaft 29, the rock-shaft 121 being vertically mounted on a proper part of the
frame A.
In order to open and close the respective branches 120 of the chute 119, there
is located within the latter at the base thereof a gate 124, which is pivoted to said
chute and has a crank 125 connected with its axis, said crank being pivoted to a
rod 126 which is operated by lever 127, operated by a cam 128, mounted on a shaft
journalled to the frame A (see Figures 34 and 34*) it being noticed that the gate
is thrown in opposite directions, and the contents of the chute are alternately
discharged through its branches. The material is now to be weighed. Below the
chutes 120 are two weighing apparatus M, the pans of which are below the
branches 120 of the chute 119 (see Figure 34) said apparatus being automatic and
similar to that shown in the Specification of U.S. Letters Patent No. 376,883
granted to me on the 17th day of January 1888. When a predetermined quantity
of material enters the scale-pan the latter is tilted and the material drops into the
chute J and is thus directed into the bag.

page_text: In order to obtain accuracy in weighing, the box 112 is adjusted to weigh a
quantity slightly less than that of the full weight. The box is filled and overflows,
the overflow being guided laterally by a spout 129 at the side of a guide-chute 130
above the box 113 the overflow thereby dropping into a cylinder or box 131,
having a false bottom or rotary disc 132, to which rotary motion is imparted by
means of a shaft 133, a pulley 134, an endless belt or chain 135, the shaft 29, and
a pulley 136 on the shaft 29, to which motion is imparted by means of bevel-
gearing 137 and a driving-wheel 138 the latter being mounted on the horizontal
shaft N on the frame A.
Motion is imparted to the endless apron of the elevator L by means of a gear-
wheel 138 meshing with a pinion 139, a pulley 140, an endless belt or chain 141,
and pulley 142.
The bottom proper 143 of the box 131 has two openings 144, which register.
with two discharge pipes or chutes 145 146 which latter communicate, respectively
with the two pans of the weighing apparatus M. The false bottom 132 has two
rows of perforations which are adapted to communicate with the two openings 144,
respectively. (See Figure 33.) On one side of the cylinder 131 and in the
bottom 143 is an opening 147, which communicates with a pipe 148 the latter
leading to the hopper K. (See Figures 30 and 46.) As the false bottom rotates
and its perforations are filled with coffee or other material, the latter remains on
the bottom proper 143 until the said perforations reach the perforations 144, the
coffee or the like then dropping into the pipes 145 and 146, and so reaching the
scale-pans M. The pans are supplied from the branches 120 with about the amount
to be weighed, but the few beans or grains of material from within the pipes 145
or 146 drop into the scale-pans and cause the latter to receive their full weight
whereby they descend after which they are tilted by a descending rod or lever 149,
and the contents enter the feed-pipe and so reach the bag, said rod or lever 149
being employed in other weighing apparatus for a similar purpose. The surplus
beans or grains in the box 131 pass through an opening 131× in a diaphragm or
deflector 131×× in said box, and so reach the opening 147 and the pipe 148, by
which they are directed into the hopper K. (See Figure 32.) A brush 132* is
within the box for each pipe 145 and 146 so as to prevent binding or clogging of
the material. In the scale-beams, at the centres thereof, are depending pipes 150
with which the pipes 145 and 146 are respectively in communication. Below the
said pipes 150 are deflectors 151 of inverted shape, one side of each of which
directs the scale-pans and the other to a hopper 152, which is in communication
with the hopper H. Now when the pan descends the pipes 150 are directed
toward the hopper 152, and the descending beans or grains or material are
deflected from the pans and rolling down the side of the deflector toward the
hopper 152 enter the latter, the supply to the scale-pans thus being cut off.
The above described measuring and weighing mechanism embodies a number of
novel devices, and they are shown here simply to give a correct idea of the whole
machine, of which the devices herein described form a part.
Having now described the mechanism by which the material to be packed is
delivered to the bags contained in the pockets, I will resume my description of the
apparatus which directly operates upon the bag.
Located in the plate J is an opening with an attached spout 153 which is in the
path of the pockets-one, 95*, as seen in Figure 1, resting over it. Across said
opening is a bridge 154, on which the bags rest while or after being filled. Now
should the bottom of the bag be improperly glued or closed, it will open and allow
the contents of the bag to escape through the space; and enter the spout 153 by
which they are directed to a box or other place of collection.
The rim J, now moves the distance of another tooth and the bag having its
bottom properly closed, and its contents retained, is carried over the pin or pins 155
(see Figs. 1 and 35) said pins passing through the bottom of the table J near the
periphery thereof and connected with a flat spring or spring-plate 156, the latter
being secured to a lever 157, which is pivoted to the frame A, and carries a

page_text: tooth 158 which is engaged by a ratchet-wheel 159, the teeth whereof are irregular,
whereby shaking motions are imparted to the bag, while it is stationary over the
pins and the contents of the latter are shaken and packed.
The spring 156 being quick-acting, acts to quickly lower the pins just a little
ahead of the descent of the package. Then the latter drops on the bed or table
and thus gets an additional shake.
A portion of the periphery of the ratchet 159 is untoothed, as at 160, so that
there is a dwell in the shaking action, and the pins are lowered below the table
when the pockets are in motion.
:
The movement of the pocket which carries the bag from over the shaking pius
brings it to the position in which its top is closed down and the package substan-
tially completed. In this position the bag rests upon a plunger, 198, which passes,
as is shown in Figure 37, through an opening in the bottom of the table ; the
said plunger being attached to levers 199 and 200 and actuated by a cam 201
secured to shaft 202. After having come to a standstill over plunger 198 the
said plunger moves downward carrying the filled bag with it and then upward.
During this upward movement of the bag, folding-devices substantially similar to
those described in connection with the folding of the bottom of the bag are brought
into action a plate 185 moving inward to fold down the back of the bag, and
triangular folders 184 following closely after said plate and engaging the upwardly-
projecting sides of the bag. These folders commence to turn outward during the
last portion of the elevation of the bag on plunger 198, and, when the bag has been
again raised to the level of the top of table J, the back flap is folded down upon
the contents and the side flaps turned out. The folder plate 185 is then withdrawn
and the folder plate 192 moves forward to fold down the front flap of the bag upon
the contents thereof and over the back flap. This folder plate 192 is secured
to a sliding bar 194 which reciprocates in the fixed guide by means of a spring-
tongue 194 and has secured to its top friction-rolls 193. A reciprocating motion
is given to the bar 194 by the cam 197 through the medium of the pivoted
lever 196 and the link 195. During the inward motion of the sliding bar 194,
plate 192 is held in a position slightly above the top of the pocket by the
spring 194× until the said plate is in position or nearly so, upon the top of the bag
when the plunger 180 moves downward coming in contact with the rollers 193 and
pressing the plate 192 down upon the top of the bag during the latter part of its
inward motion.
The described method of folding down the top of the bag by which the bag is
lowered and then brought gradually upward during the operation of folding down
the first flaps and by which the folding-plate which turns down the front flap of the
bag engages the flap at a level above the top of the pocket and above the contents
of the bag, is highly important as by these devices I am enabled to fold a neat
square top upon the package without having any fixed forming device within the
same. The granular filling of the package of course would afford an insufficient
resistance to serve as a forming device, but in connection with the peculiar move-
ments noted the said contents do afford sufficient resistance to insure the proper
folding of the top.
Before describing the remaining operations of folding the top of the bag I will
here note that after the plunger 198 has accomplished its function and raised the bag
to the level of the top of table J the package is firmly grasped and compressed in the
pocket in which it has heretofore remained in loose contact; or rather I should say
that the moveable side of the pocket moves in while and after the plunger is raising
the package. This is accomplished by forming the pocket in sections (see Figs. 42
and 44) one section, 161, being moveable and guided on the other section as
shown or in any convenient way. The moveable section 161 is thrust in so as to
clamp the bag in the pocket. As shown, this is accomplished by a sliding bar, 163,
moving in guides secured to the top of table J and having rollers 162 arranged to
come in contact with the movable side 161 of the pocket. The bar is moved
inwardly at the proper time by means of a cam 166, lever 165, and link 164, and
:

page_text: the package is held tightly clamped during the whole operation of folding down and
securing its top, and then released as. the series of pockets resume their intermittent
rotation.
To return now to the folding of the top of the bag it is necessary to apply paste
to the outwardly-turned triangular side folds and having been pasted, the angular
folders 184 turn inward and fold the triangular side folds down upon the front and
back flaps of the bottom: The folding plate 192 being withdrawn in advance of
the inward movement of the angular folding blades. The said angular folding
blades 184 are then drawn backward to their original position, and the plunger or
presser-plate 180 again moves down upon the folded top of the bag defining and
pressing the pasted portions together. As shown in the drawing the plunger 180 is
actuated by a cam 182 on the shaft 183 by means of connecting links 181*. And
it is guided in a slide 181.
The mechanism shown in the drawings for actuating the angular folder 184, are,
for giving them their reciprocating motion, the cam 187, the lever 186, and the
sliding bar 185× connected with said lever by a link as shown. The folders lic
parallel to the bar 185* and are journaled to it by means of shafts which are
provided with elongated gear-wheels which engage a rack-bar 188, which bar is
moved by a cam 191 through the medium of lever 190 and link 189. The folder
plate 185 is operated by a cam 191**** through the medium of lever 191***,
link 191**, and the sliding bar 191*.
I will next describe the mechanism shown in the drawings for applying paste to
the triangular flaps formed on the top of the bag as above described. 167 (see
Figs. 36 and 37) is a paste-carrying disc or table centrally pivoted on a sliding
bar 172 and having a ratchet 168 secured to its axial pin. 169 designates a pawl
which is pivoted on an arm 170, said arm being in turn connected with a frame by
means of a link 171. It will readily be seen as the slide 172 moves in or out the
action of the pawl will be to turn the ratchet and revolving paste table 167. The
sliding plate 172 is given a reciprocating motion by means of the cam 175 with
which it connects through link 173, and levers 174 attached to the ends of the rock-
shaft 174 one engaging the link 173, and the other the cam 175 as shown in
Figure 36.
176, 176 are pasters secured to the ends of vertical rods which in turn are secured
to the sliding rod 177, which rod is given an up and down motion by the cam 179
with which it is connected by a link 178. The pasters are arranged so as to come
immediately over the outwardly-turned triangular flaps of the bag top.
The action of these devices are as follows: The paste-carrying table 167 is
moved so as to come beneath the pasters 176; the said pasters are then moved
downward so as to come in contact with the table and take a supply of paste from
it; they then move upward and the table is retracted or moved back out of their
path and the pastors are then again moved downward until they come in contact
with the outwardly-turned flaps of the bag top secured on the angular folding
plates 184; to which flaps they impart the requisite amount of paste and they are
then moved upward out of the way when the angular folders turn inward to fold the
flaps down upon the top of the bag.
When the closing of the top of the bag is completed, the rim J¹, again moves,
causing the pocket 95, having the bag within the same, to pass under a steam or
drying chamber 203 (see Figs. 1 and 3), mounted over portions of the table J,
steam being admitted into sail chamber, as at 204, and discharged, as at 205. The
bottom of the dryer is flat and it rests upon the top of the, bags, being pressed down
if desired by springs (see Fig. 3).
The bag after having passed under said drying chamber must now be removed from
the pocket 95. To accomplish this I use a plunger 206 (see Fig. 39) operated by
means of a link 207, lever 208, and cam 209, are employed, said cam being secured
to a shaft 210 mounted on the frame A, said plunger and the bag in their raised
positions being shown in dotted lines.

page_text: Pivoted to a depending stem, 206×, of the plunger 206, is an elbow lever 211
which is held in elevated position by means of a spring 212.
As said plunger rises it carries with it the elbow lever 211, the limb 213 of which
enters the pocket 95. One of the rollers 214 pivoted to the other limb of the
lever strikes the under side of the table J and causes said limb 213 of the lever 211
to move outwardly, as indicated by an arrow, and consequently presses against the
inside of the movable section 161 of the pocket 95, and restores it to the open
position shown in Figure 44 prior to receiving another bag to be filled, &c.
When the bag is raised clear of the pocket 95 it is in position to be directed to
an endless belt or apron 215 from which it is taken and stored, shipped, &c.,
(see Figs. 39, 40 and 41). In order to accomplish this a slide 216 guided in the
frame A with slots 217 is employed, the same being operated by a link 218,-an
elbow lever 219, and a cam 220, secured to a shaft 221 mounted on the frame A.
When the bag leaves the pocket 95 it is in an oblique position relatively to the
endless belt or apron 215 (see Fig. 40).
In order to properly place the bag on said endless belt or apron, the slots 217
are partially oblique, so as to guide the slide 216 in both a forward and an oblique
direction, as indicated by arrows in Figure 40, and thus cause the bag to turn on
the finger 222 so as to be in position shown in Figure 41, said finger 222 being
secured to a guard or a wall 223 mounted on the frame A, and located on the
side of the endless belt or apron 215.
Secured to the frame A are pins 224 which enter the slots 217 in the slide 216.
As the latter is moved forward it is, owing to the slots and pins above-mentioned,
guided in the oblique direction herein-before described.
In Fig. 30 the endless belt or apron 215 is operated by means of a pulley 225
around which said apron passes, an endless chain or belt 226, a pulley 227. and
an endless belt or chain 228 which passes around pulleys 229, and 230 said
pulleys being properly mounted on the frame A the pulley 230 being connected
with the pulley 142, or shaft thereof, as seen. at the top of said Figure 30.
Motion is communicated to the different parts of the device by the driving
shaft D, (Fig. 47) having a worm thereon which engages with a worm-wheel on
the shaft 29, the latter having the bevel gear-wheel 231 which meshes with a bevel
gear-wheel 232, on the shaft B'. The bevel gear-wheel. 233 on the shaft B' meshes
with a bevel gear-wheel 234 on the shaft 37, imparting motion to the same.
cog-wheel 235 on the shaft B' operates the conveyor.
The

The bevel gear-wheel 236 on the shaft 37 meshes with a gear-wheel 237 on the
shaft B, and operates the latter. The bevel gear-wheel 238 on the shaft 29 meshes
with a bevel gear-wheel 239 on the shaft B and. imparts motion to the same.
bevel gear-wheel 240 on the shaft B meshes with a bevel gear-wheel 241 on the
shaft imparting motion thereto. The bevel gear-wheel 242 on the shaft B
meshes with the bevel gear-wheel 243 on the shaft 19 and imparts motion thereto
as shown in Figure 47.
