PROVISIONAL SPECIFICATION.
Improvements in Glue Making Machinery.
I, PETER COOPER HEWITT, of 11, Lexington Avenue, New York City,
United States of America, Manufacturer, do hereby declare the nature of this
invention to be as follows:-
Heretofore, in the manufacture of glue, it has been customary to set the glue in
moulds, forming cakes, then to cut the cakes into sheets, and lay the sheets out on
the nets by hand; place the nets in stacks, also by hand, and to remove them to the
drying room, there to remain until the glue is dry, after which the glue is removed,
the nets stacked, by hand, into piles of convenient height which are returned to
the glue making department, to be again unstacked, filled, and stacked by hand,
and returned to the drying room.
The object of my invention is to provide a glue making machine in which the
process of making glue may be carried on continuously and in which the nets may
be unstacked, loaded with sheet glue, and stacked by machinery ready for trans-
portation to the drying room, thus doing away with manual labour.
My invention consists in the combination of a device for forming glue into
sheets, for spacing and subdividing the sheets, and for cutting the sheets into
sizes for delivery to the drying nets, mechanism for removing the nets from the
stack and carrying them forward successively to receive the subdivided sheets of
glue, and mechanism for placing the filled nets in stacks and removing the stacks
from the machine, all as will be hereinafter more fully described.

In the diagram, Figure 1, I have shewn the apparatus 1 for cooling the glue and
forming it into sheets, arranged in operative relation to the separator and sub-
divider 2. I have also shewn the relation of the net unstacker 3, net conveyer 4,
net stacker 5, and the stack remover 6, to each other. The glue cooling and sheet
forming apparatus 1 is shewn and described in my application for Letters Patent
of the United States No. 481,621 entitled "Apparatus for cooling glue and forming
it into sheets," filed July 27th 1893. As this apparatus forms no part of my
present invention, except in so far as it enters into combination with other mechanism,
a complete description of the same will not be necessary.
On
The liquid glue is supplied through a suitable valve 7 to a cooler consisting of a
series of cooling cylinders 8 upon which the glue is spread out cooled and delivered
in the form of a sheet to the endless conveyer 9, the said conveyer cousisting of a
series of cords passing over a roller 10 in the glue cooler and sheet former 1 and
over a roller 11 in the. separator and subdivider 2. In the side pieces 12 of the
frame 13 of the separator and subdivider 2 are journalled drums 14, 15, 16, 17, formed
of wheels which receive the endless cords 18, 19. The drums 14, 16, are journalled
in the frame 13 in a plane above the drums 17 and 15. The drums 14, 15, receive
the cords 18, and the drums 16, 17, receive the cords 19, and the paths of these.
two series of endless cords cross each other at 20, at or near the centre of the
machine. The cords 18 pass over and lie in the grooves of a grooved drum 21 and
the cords 19 pass over and lie in the grooves of a grooved drum 22. The journal
boxes of the drums 14, 17, are placed in slots in the end of the frame 13 and are
adjusted by screws and nuts, so that the tension of the endless cords may be
adjusted. The roller 11 is journalled in the frame 13 with reference to the drum 14
and cords 18, so that the endless conveyer 9 may deliver the sheets of the glue
formed in the apparatus 1, to the series of endless cords 18. In an upward
extension 23 of the frame 13 is journalled a shaft 24 carrying arms provided with
cutters 25 which are capable of making contact with the periphery of the drum 21
as they are revolved, thereby cutting the continuous sheet of glue delivered by the
endless conveyer 9 to the cords 18, in lengths suitable for filling the nets.
the end of the shaft 24 is mounted a spur wheel 26 which is engaged by a pinion 27
mounted on a shaft 28 journalled in the extension 23. The said shaft is provided
with a sprocket wheel 29 receiving an endless chain 30 which passes around a
sprocket wheel 31 on the shaft of the drum 14. The shaft 32 of the drum 16 is
provided with a pulley 33 which receives the belt 34 by which power is supplied
to the machine. On the shaft 32 is mounted a pinion 35 which engages a spur
wheel 36 on the shaft 37 journalled in the frame 13. Above the circumferentially
grooved drum 22 is journalled a shaft 38 which carries a series of rotary cutters 39
the peripheries of which are near or in contact with the upper surface of the
drum 22. The shaft 38 is journalled in adjustable boxes in pillow blocks 40 secured
to the top of the frame 13, and the said shaft is furnished with a sprocket wheel 41
which receives motion through a chain 42 from a sprocket wheel 43 on the shaft 37.
The shaft 44 of the drum 15 is provided with a spur wheel 45 which takes motion
from the spur wheel 36 on the shaft 37 and upon the ends. of the said shaft 44 are
spur wheels 46, 47, which engage pinions 46" on the ends of a shaft 46° journalled
in the frame 13, said shaft also carrying next said pinions, gear wheels 46° engaging
pinions 48 on short shafts 49 projecting inwardly from opposite sides of the frame 13
and carrying on their inner ends sprocket wheels 49 engaging endless chains 50.
The said chains 50 move in inclined planes opposite grooves formed in the sides of
the frame 13 parallel with the path of the cords 19. The lower ends of the
chains 50 are received on sprocket wheels 51 secured to shafts 52 which project

page_text: outwardly through the sides of the frame 13. Each shaft 52 is provided on its
outer end with a spur gear wheel 53. On the opposite side of the line of inter-
section of the cords 18, 19, is arranged a similar pair of chains 54 running in
inclined planes opposite grooves in the sides of the frame 13, the said grooves
being parallel with the cords 18. The shafts 55 carrying the sprocket wheels 56
which support and drive the chains 54, are furnished outside of the frame 13 with
spur wheels 57 and the spur wheels 53 and 57 are connected mechanically by
intermediate spur wheels 58 journalled on studs 59 projecting from the sides of the
frame. The upper ends of the chains 54 are supported by sprocket wheels 54"
which turu on studs projecting inwardly from the sides of the frame 13. By means
of this construction the chains 50 and 54 are made to revolve simultaneously in the
same direction.
Upon each side of the machine a bar 60 is pivotally connected with a link of
each of the chains 50 and 54 and the said bars 60 are connected by cross bars 61.
The said cross bars, in connection with upwardly projecting longitudinal plates 62,
form a transfer table for carrying a sheet of glue from the cords 18 to the cords 19,
as soon as the sheet of glue comes into position on the cords 18. The cords 19
are made to travel faster than the cords 18 by making the drum 16 which drives
the cords 19, of slightly larger diameter than the drum 14 which drives the
cords 18. The difference between the speed of the cords 18 and 19 is such as to
leave a space of some six or eight inches between the sheets when delivered on the
cords 19 by the transfer table, or sufficient space to correspond to the space existing
between the nets on the net conveyer, as will be described later on. The mechanism
by which the sheets are spaced I shall call a spacer, to obviate the necessity of
further describing it.
It will thus be seen that the table 62 is carried forward to the receiving end of
the machine by the chains 50 and 54 and that, owing to the inclination of the
chains, the table 62 is inclined so that when those links of the said chains pass
around the sprocket wheels 49, 51, 54", and 56, by which the bars 60 arc
supported; these chains carry the bars 60 by which the table 62 is supported,
upwardly with a parallel motion, the bars 60 being guided by the extension of their
ends beyond their pivotal connection with the chains which project into the slots.
in the side of the frame so that the bars of the table being parallel with the
cords 18 engage the entire sheet of glue carried by the cords, lifting the glue from-
the cords. The transfer table 62 is raised by the chains as they revolve, and at
the same time is moved forward. At the instant the said transfer table comes into
contact with the glue sheet carried by the cords, the velocity of its forward motion
is the same as that of the cords 18 and the glue sheet carried thereby. A further
movement of the chains carries the table with the sheet of glue thercon toward
the delivery end of the machine, at the same time tilting the table so as to bring
the sheet of glue parallel with the cords 19 when the bars 60, together with the
table, are dropped below the level of the cords by the carrying of the pivotal
connections of the bars 60 with the chains around the sprocket wheels 49 and 56
at the delivery ends of the chains. As the transfer table descends, its forward
motion is retarded, the motion being the resultant of the forward and downward
movements, so that when the glue sheet is delivered by the transfer table to the
cords 19 the transfer table is moving at the same speed as the cords 19, which
speed, although slower than the speed of forward movement of the transfer table,
when passing from the cords 18 to the cords 19, is faster than that of the cords 18.
The sheet is carried forward by the cords 19 under the cutters 39 which cut the sheet
into strips. Beyond the cutters 39 is arranged a shaft 63 which is provided with a
sprocket wheel 64 taking power through the chain 65 from a sprocket wheel 66 o
the shaft 37. The shaft 63 carries two discs 67, 68, in which are fastened
knives 69 parallel with the shaft 63. The knives 69 are arranged with reference
to the strips of glue carried by the cords 19 so that the said knives will crat the
strips into short lengths or squares by contact of the knives with the roller 70
journalled in the frame 13. The glue in its passage to the knives 69 and roller 70

page_text: is transferred from the cords 19 to the cords 71. passing over the said roller 70 also
around a roller 72 journalled in pillar blocks 73 a short distance from the delivery
end of the machine. Endless chains 74 run over sprocket wheels 75, 76, carried
by shafts 78, 79. The said chains 74 are arranged parallel with each other and
at a suitable distance apart to receive the net frames 80 and form an endless
carrier for conveying the said frames under the separator and subdivider and under
the roller 72.
·
On opposite sides of the endless carrier at the receiving end of the machine are
arranged standards 81, 82, two upon each side of the carrier. The distance
between the standards 81, 82, of one side and the standards of the opposite side
is sufficient to receive between them the net frames 80. The net frames are
provided with two notches in each side for receiving the retaining pawls 83 which
are capable of projecting beyond the inner faces of the standards 81, 82, and also
of dropping back into a recess in the standard when released, each pawl being
provided with a weighted arm 84 for causing it to drop back when released in the
manner presently to be described. In a plate covering the back of the recess
containing the pawl 83 is inserted a rod 84 which is pressed forward into contact
with the pawl 83 by the spiral spring 85 surrounding it and abutting against the
plate. The outer end of the rod 84" passes through an arm 86 secured to a rock
shaft 87 journalled in ears projecting from the standard 82. Upon the rod 84",
outside of the arm 86, is placed a wing nut 88 and upon the shaft 87 is secured an
arm 89 extending toward the centre of the machine into the path of a tripper 90
secured to the net lowering bar 91. The pawls 83 and accompanying devices are
the same upon opposite sides of the machine but oppositely arranged with respect
to each other so that the pawls on one side engage the notches in one side of the
net frame and the pawls on the other side engage the notches in the other side of
the frame. The bars 91 are connected at opposite ends with toggle joints 92,
the said toggle joints being oppositely arranged with respect to each other and a
pair of oppositely arranged toggle joints 93, 94, are connected with the middle of
each bar 91 and also with the Hoor and the intermediate pivots of the toggle joints
are connected by rods 95 with the central pivot of the toggle joints at the ends
of the bars 91. This arrangement of toggle joints and bars forms a parallel
motion whereby the bars 91 are kept in a horizontal position when raised or
lowered in the manner hereinafter described. Each bar 91 carries a roller 96
which rides upon a cam 97 secured to the shaft 98, there being one such cam on
each end of the said shaft, and to the shaft 98 is imparted an intermittent rotary
motion by a segmental pinion 99 on the said shaft and a segmental gear wheel 100
on the shaft 101 which receives its motion from the shaft 78 through mitre
gearing 102, the shaft 103, and mitre gearing 104. The stack of net frames 80 is
delivered to the unstacking device from the platform 80. Posts 81ª, erected on
the said platform, act as stops when placing the net frames in position to be fed to
the unstacker.
At the opposite end of the machine, beyond the roller 72, and upon opposite
sides of the endless net frame carrier, are arranged posts 105, 106, and in the said
posts are pivoted spring pressed pawls 107 which are capable of engaging the
notches in the net frame, and below the level of the endless chains 74 is arranged
mechanism like that already described, comprising bars 91", toggle joints 82, 83ª,
93, 94, rods 95, the cam 97", segmental pinion 99ª, segmental spur wheel 100%,
journalled on the shaft 101*, which takes power through mitre gearing 104",
shaft 103, and mitre gearing 102", from the shaft 79. Above the chain 7+, at the
delivery end of the machine, is arranged a frame 107 in which are journalled
rolers 108 for receiving and supporting the stack of frames when loaded and
ready for delivery, and posts '109, 110, support studs 111, 112, 113, and 114, upon
which turn the sprocket wheels 115, 116, 117, and 118, there being one set of four
sprocket wheels on each side of the machine and upon the said sprocket wheels is
supported an endless chain 119, carrying bars 120. Each sprocket wheel 118 is
provided with a pinion 121 which receives motion from a spur wheel 122, to which

page_text: is attached a segmental pinion 123, which is engaged by the segmental spur
wheel 124 on the shaft 125, the said segmental spur wheel having a portion of its
periphery plain to receive the stop 126 formed on the segmental pinion. The
shaft 125 is provided with a spur wheel 127 which is connected through an
intermediate spur wheel 128 with a pinion 129 on the shaft 130 and the said
shaft 130 carries a spur wheel 131 which receives motion from a pinion 132 on
the shaft 79. The rollers 108*, which form a continuation of the series of
rollers 108, receive motion through the chain 133 from a sprocket wheel 134 on
the shaft 79. The first of the series of rollers 108 is provided with a sprocket
wheel for receiving the chain and is connected with the outer rollers in the series
by a chain gearing.
The operation of my, improved machine is as follows:-The melted glue being
delivered by the valve 7 to the cylinders 8 is spread out and formed into a thin
sheet and cooled as it is carried forward by the cylinders the said cylinders being
cooled by the passage of cold water through them, or the application of cold
water to the under surface of the cylinders, as described, in the application for a
patent to which reference has been made. The cooled sheet of glue is delivered
to the endless conveyer 9 which in turn delivers it to the series of cords 18 which
carry it forward over the drum 21 where it is cut into lengths by the knives 25.
As soon as the sheet of glue comes above the table 62, the said table is raised by
the chains 50, 54, lifting the sheet of glue from the cords 18, the continued
forward movement of the said chains 50, 54 carries the table rapidly forward at
the same time tilting it so as to compel it to take a position parallel with the
cords 19. When the table is dropped, it leaves the sheet of glue upon the
cords 19. The said cords 19 nove forward with a velocity which is greater than
the velocity of the cords 18, thereby causing, the sheet of glue to advance
sufficiently to leave a space of six or eight inches between the sheet deposited and
the next succeeding sheet. The table 62 after being dropped is quickly returned
to its position at the receiving end of the machine, while in the meantime another
sheet of glue has been carried forward into position to be taken by the table and
carried forward to the cords 19, as before described. By carrying forward the
sheet of glue from the cords 18 to the cords 19 and increasing the speed of its
travel on the cords 19 sufficient space is left between the sheets to allow for
spaces between the nets, the spacing being governed by the thickness of the net
frames also by the distance required between the nets to allow for the operation
of the net stacker. The sheet of glue is carried forward by the cords 19 underneath
the revolving cutters 39 which divide it into strips of suitable width and the
said strips are moved forward and delivered to the cords 71. In the passage
of the strips over the roller 70 the said strips are cut up into suitable lengths
by the knives 69 and the sheet of glue thus subdivided is carried forward by
the cords 71 to the roller 72 where it is delivered to the net 80. While the sheet
of glue is being formed, cut into sheets, spaced, cut into strips, and further
subdivided by being cut into small squares, preparatory to its delivery to the
.net frames and the frames having been placed in the form of a stack above the
unstacking mechanism, the net frames 80 are delivered one by one to the endless
chain 74 by the unstacking mechanism 3 which operates as follows:-The stack
of frames being held by the pawls 83 to engage the lower frame of the stack,
the bars 91 are lifted by the cams 97. As the said bars 91 come into contact
with the under surface of the lower frame the trippers 90 engage the arms 89
thus turning the rock shaft 87 and, through the movement of the arms 86, with-
drawing the spring pressed rods 84° from the pawls 83, allowing the weights 84
to tilt the pawls and disengage them from the net frames 80, as the weight of the
net is taken from the pawls by the bars 91. The continued movement of the
cams 97 allow the bars 91 to descend, thus lowering the entire stack of net frames
and at the same time releasing the arms 89, 86, allowing the spring pressed
rods 84 to move forward against the pawls 83 so that when the second frame
from the bottom of the stack reaches the pawls the said pawls engage the

page_text: notches in the frame and support the entire stack. The lower net frame of the
stack being below the device continues its descent until it rests upon the endless
chains 74 which move the frame forward from beneath the stack of frames, so as to
permit of another excursion of the bars 91. The chains 74 and the intermittent
unstacking mechanism are timed with reference to each other, and to the delivery
of the sheet from the sheet separator and subdivider so that the cords 71 may
deliver a subdivided sheet of glue to a net 80 as it passes under the roller 72
the required intermittent motion of the unstacking mechanism being secured by
the segmental pinion 99 and wheel 100 the said wheels being connected with the
same source of power that operates the other portions of the machine. The
frames after being filled are still carried forward until arrested by the posts 74*,
when they are received by the bars 91 of the stacking mechanism which
correspond to the bars 91 of the unstacking mechanism at the opposite end of
the machine, while the said bars are in their lowest position, and the said bars
are raised by the cam 97, in the manner above described, lifting the net
frame 80 from the chain 74, carrying upward with the said frame the superposed
frames until it is brought into engagement with the pawls 107 thus adding one
frame after another to the bottom of the stack until a stack is formed of
convenient size for handling. The height of the stack is controlled by the gearing
connected with the endless chain 119. The said gearing takes its motion from
some moving part of the machinery or from the source of power and is timed so
as to work synchronously with the unstacker and the separator and subdivider.
The chain 119 is moved forward intermittently by the segmental wheel 124, the
segmental pinion 123, the spur wheel 122, pinion 121, and sprocket wheel 118.
The bars 120 connected with the chains 119 on opposite sides of the machine,
engage the stack of net frames 80 and move it forward over the rollers 108 until
it is engaged by the power driven rollers 108, which carry it away from the
delivery end of the machine, to be transferred to the drying room. ⚫
Although I have described my improvement as consisting of a glue cooler, a
subdivider, and spacer, a net unstacker, and a net stacker, I do not confine
myself to this arrangement, as the unstacker and the subdivider aud spacer may
be omitted and the glue may be delivered directly to the nets carried by the
endless chains, and the nets may be stacked in the manner already described."

Improvements in Glue Making Machinery.
I PETER COOPER HEWITT, of 11 Lexington Avenue, New York City, United
States of America, 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:—
Heretofore, in the manufacture of glue, it has been customary to set the glue in
moulds, forming cakes, then to cut the cakes into sheets and lay the sheets out on
the nets by hand; place the nets in stacks, also by hand, and to remove them to
the drying room, there to remain until the glue is dry, after which the glue is
removed, the nets stacked by hand into piles of convenient height, which are returned
to the glue-making department, to be again unstacked, filled, and stacked by hand,
and returned to the drying room. The object of my invention is to provide a glue-
making machine in which the process of making glue may be carried on continuously,
and in which the nets may be unstacked, loaded with sheet glue, and stacked by

page_text: machinery ready for transportation to the drying room, thus doing away with
manual labour.
My invention consists in the combination of a device for forming glue into sheets,
for spacing and subdividing the sheets and for cutting the sheets into sizes for

Similar figures of reference indicate corresponding parts in all the views.
In the diagram Figure 1, I have shown the apparatus 1, for cooling the glue and
forming it into sheets, arranged in operative relation to the separator and sub-
divider 2. I have also shown the relation of the net unstacker 3, net conveyer 4,
net stacker 5, and the stack remover 6, to each other. The glue cooling and sheet
forming apparatus 1 is shown and described in my application for Letters Patent of
June 12th 1894 No. 11426, entitled "Improvements in processes and apparatus for
cooling glue and forming it into sheets." As this apparatus forms no part of my
present invention, except in so far as it enters into combination with other mechanism,
a complete description of the same will not be necessary.
The liquid glue is supplied through a suitable valve 7 to a cooler consisting of a
series of cooling cylinders 8, upon which the glue is spread out, cooled and delivered
in the form of a sheet to the endless conveyer 9, the said conveyer consisting of a
series of cords passing over a roller 10 in the glue cooler and sheet former 1, and
over a roller 11 in the-separator and sub-divider 2.
'
In the side pieces 12 of the frame 13 of the separator and sub-divider 2, are
journalled drums 14, 15, 16, 17, formed of wheels which receive the endless
cords 18, 19. The drums 14, 16, are journalled in the frame-13 in a plane above the

page_text: drums 17 and 15. The drums 14, 15, receive the cords 18, and the drums 16, 17
receive the cords 19, and the paths of these two series of endless cords cross each
other at 20, at or near the center of the machine. The cords 18 pass over and lie
in the grooves of a grooved drum 21, and the cords 19 pass over and lie in the
grooves of a grooved drum 22. The journal boxes of the drums 14, 17 are placed
in slots in the end of the frame 13, and are adjusted by screws and nuts so that the
tension of the endless cords may be adjusted. The roller 11 is journalled in the
frame 13 with reference to the drum 14 and cords 18, so that the endless conveyer 9
may deliver the sheets of the glue formed in the apparatus 1, to the series of endless
cords 18.
The
In an upward extension-23 of the frame 13, is journalled a shaft 24, carrying
arms provided with cutters 25, which are capable of making contact with the
periphery of the drum 21, as they are revolved, thereby cutting the continuous sheet
of glue delivered by the endless conveyer 9 to the cords 18, in lengths suitable for
filling the nets. On the end of the shaft 24 is mounted a spur wheel 26, which is
engaged by a pinion 27 mounted on a shaft 28 journalled in the extension 23.
said shaft is provided with a sprocket wheel 29, receiving an endless chain 30, which
passes around a sprocket wheel 31 on the shaft of the drum 14. The shaft 32 of
the drum 16 is provided with a pulley 33, which receives the belt 34 by which
power is supplied to the machine. On the shaft 32 is mounted a pinion 35, which
engages a spur wheel 36 on the shaft 37 journalled in the frame 13.
Above the circumferentially grooved drum 22 is journalled a shaft 38, which
carries a series of rotary cutters 39, the peripheries of which are near or in contact
with the upper surface of the drum 22. The shaft 38 is journalled in adjustable
boxes in pillow blocks 40 secured to the top of the frame 13, and the said shaft is
furnished with a sprocket wheel 41, which receives motion through a chain 42, from
a sprocket wheel 43 on the shaft 37. The shaft 44 of the drum 15 is provided with
a spur wheel 45, which takes motion from the spur wheel 36 on the shaft 37, and
upon the ends of the said shaft 44, are spur wheels 46, 47, which engage pinions 46*
on the ends of a shaft 46, journalled in the frame 13, said shaft also carrying next
said pinions, gear wheels 46°, engaging pinions 48 on short shafts 49, projecting
inwardly from opposite sides of the frame 13 and carrying on their inner ends
sprocket wheels 49 engaging endless chains 50. The said chains 50 move in
inclined planes opposite grooves formed in the sides of the frame 13, parallel with
the path of the cords 19. The lower ends of the chains 50 are received on sprocket
wheels 51, secured to shafts 52, which project outwardly through the sides of the
frame 13. Each shaft 52 is provided on its outer end with a spur gear wheel 53.
On the opposite side of the line of intersection of the cords 18, 19, is arranged a
similar pair of chains 54, running in inclined planes opposite grooves in the sides of
the frame 13, the said grooves being parallel with the cords 18. The shafts 55,
carrying the sprocket wheels 56 which support and drive the chains 54, are
furnished outside of the frame 13 with spur wheels 57, and the spur wheels 53
and 57 are connected mechanically by intermediate spur wheels 58, journalled on
studs 59 projecting from the sides of the frame. The upper ends of the chains 54
are supported by sprocket wheels 54 which turn on studs projecting inwardly from
the sides of the frame 13. By means of this construction the chains 50 and 54 are
made to revolve simultaneously in the same direction.
Upon each side of the machine, a bar 60 is pivotally connected with a link of
each of the chains 50 and 54, and the said bars 60 are connected by cross bars 61.
The said cross bars, in connection with upwardly projecting longitudinal plates 62,
form a transfer table for carrying a sheet of glue from the cords 18. to the cords 19,
as soon as the sheet of glue comes into position on the cords 18. The cords 19 are
made to travel faster than the cords 18, by making the drum 16 which drives the
cords 19 of slightly larger diameter than the drum 14 which drives the cords 18.
The difference between the speed of the cords 18 and 19 is such as to leave a space
of some six or eight inches between the sheets when delivered on the cords 19 by
the transfer table, or sufficient space to correspond to the space existing between

page_text: the nets on the net conveyer, as will be described later on. The mechanism by
which the sheets are spaced, I shall call a spacer to obviate the necessity of further
describing it.
It will thus be seen that the table 62 is carried forward to the receiving end of
the machine by the chains 50 and 54, and that owing to the inclination of the
chains, the table 62 is inclined so that when those links of the said chains pass around
the sprocket wheels 49, 51, 54 and 56 by which the bars 60 are supported, these
chains carry the bars 60 by which the table 62 is supported, upwardly, with a
parallel motion, the bars 60 being guided by the extension of their ends beyond
their pivotal connection with the chains, which project into the slots in the side of
the frame, so that the bars of the table being parallel with the cords 18, engage the
entire sheet of glue carried by the cords, lifting the glue from the cords. The
transfer table 62 is raised by the chains as they revolve, and at the same time
is moved forward. At the instant the said transfer table comes into contact with
the glue sheet carried by the cords, the velocity of its forward motion is the same
as that of the cords 18 and the glue sheet carried thereby. A further movement.
of the chains carries the table with the sheet of glue thereon toward the delivery
end of the machine, at the same time tilting the table so as to bring the sheet of
glue parallel with the cords 19, when the bars 60, together with the table, are
dropped below the level of the cords, by the carrying of the pivotal connections of
the bars 60, with the chains around the sprocket wheels 49 and 56, at the delivery
ends of the chains. As the transfér table descends its forward motion is retarded,
the motion being the resultant of the forward and downward movements, so that
when the glue sheet is delivered by the transfer table to the cords 19, the transfer
table is moving at the same speed as the cords 19, which speed, although slower
than the speed of forward movement of the transfer table when passing from the
cords 18 to the cords 19, is faster than that of the cords 18.
The sheet is carried forward by the cords 19 under the cutters 39, which cut the
sheet into strips. Beyond the cutters 39 is arranged a shaft 63, which is provided
with a sprocket wheel 64, taking power through the chain 65 from a sprocket -
wheel 66 on the shaft 37. The shaft 63 carries two disks 67, 68, in which are
fastened knives 69, parallel with the shaft 63. The knives 69, are arranged with
reference to the strips of glue carried by the cords 19, so that the said knives will
cut the strips into short lengths or squares by contact of the knives with the
roller 70 journalled in the frame 13. The glue in its passage to the knives 69
and roller 70, is transferred from the cords 19 to the cords 71 passing over the said
roller 70, also around a roller 72, journalled in pillar blocks 73 a short distance from
the delivery end of the machinė. Endless chains 74 run over sprocket wheels 75, 76,
carried by shafts 78, 79. The said chains 74, are arranged parallel with each
other and at a suitable distance apart to receive the net frames 80, and form an
endless carrier for conveying the said frames under the separator and sub-divider
and under the roller 72.
On opposite sides of the endless carrier at the receiving end of the machine, are
arranged standards 81, 82, two upon each side of the carrier. The distance between
the standards 81, 82, of one side and the standards of the opposite side is sufficient
to receive between them the net frames 80. The net frames are provided with two
notches in each side for receiving the retaining pawls 83, which are capable of
projecting beyond the inner faces of the standards 81, 82, and also of dropping back
into a recess in the standard when released, each pawl being provided with a
weighted arm 84 for causing it to drop back when released in the manner presently
to be described.
In a plate covering the back of the recess containing the pawl 83, is inserted a
rod 84, which is pressed. forward into contact with the pawl 83, by the spiral
spring 85 surrounding it and abutting against the plate. The outer end of the
rod 84 passes through an arm 86, secured to a rock shaft 87 journalled in ears pro-
jecting from the standard 82. Upon the rod 84" outside of the arm 86, is placed a
wing nut 88, and upon the shaft 87 is secured an arm 89 extending toward the
H

page_text: center of the machine into the path of a tripper 90, secured to the net-lowering
bar 91. The pawls 83 and accompanying devices are the same upon opposite sides
of the machine, but oppositely arranged with respect to each other, so that the
pawls on one side engage the notches in one side of the net frame, and the pawls on
the other side engage the notches in the other side of the framo. The bars 91, are
connected at opposite ends with toggle joints 92, the said toggle joints being
oppositely arranged with respect to each other, and a pair of oppositely arranged
toggle joints 93, 94, are connected with the middle of each bar 91, and also with
the floor, and the intermediate pivots of the toggle joints are connected by rods 95
with the central pivot of the toggle joints at the ends of the bars 91. This
arrangement of toggle joints and bars forms a parallel motion whereby the bars 91
are kept in a horizontal position when raised or lowered in the manner hereinafter
described.
Each bar 91 carries a roller 96, which rides upon a cam 97 secured to the
shaft 98, there being one such cam on each end of the said shaft, and to the shaft 98
is imparted an intermittent rotary motion by a segmental pinion 99 on the said
shaft, and a segmental gear wheel 100 on the shaft 101, which receives its motion
from the shaft 78 through miter gearing 102, the shaft 103, and miter gearing 104.
The stack of net frames 80 is delivered to the unstacking device from the
platform 80 Posts 81° erected on the said platform act as stops when placing
the net frames in position to be fed to the unstacker.
At the opposite end of the machine, beyond the roller 72, and upon opposite
sides of the endless net frame carrier, are arranged posts 105, 106, and in the said
posts are pivoted spring-pressed pawls 107 which are capable of engaging the
notches in the net frame, and below the level of the endless chains 74, is arranged
mechanism like that already described, comprising bars 91ª toggle joints 82", 83",
93, 94, rods 95, the cam 97", segmental pinion 99", segmental spur wheel 100*
journalled on the shaft 101°, which takes power through miter gearing 104*,
shaft 103, and miter gearing 102" from the shaft 79.
Above the chain 74, at the delivery end of the machine, is arranged a frame 107*,
in which are journalled rollers 108 for receiving and supporting the stack of frames
when loaded and ready for delivery, and posts 109, 110, support studs 111, 112, 113,
and 114 upon which turn the sprocket wheels 115, 116, 117 and 118, there being
one set of four sprocket wheels on each side of the machine, and upon the said
sprocket wheels is supported an endless chain 119, carrying bars 120. Each
sprocket wheel 118 is provided with a pinion 121, which receives motion from a
spur wheel 122, to which is attached a segmental pinion 123, which is engaged by
the segmental spur wheel 124 on the shaft 125, the said segmental spur wheel
having a portion of its periphery plain to receive the stop 126 formed on the
segmental pinion. The shaft 125 is provided with a spur wheel 127, which is
connected through an intermediate spur wheel 128 with a pinion 129 on the shaft 130,
and the said shaft 130 carries a spur wheel 131, which receives motion from a
pinion 132 on the shaft 79. The rollers 108", which form a continuation of the
series of rollers 108, receive motion through the chain 133 from a sprocket
wheel 134 on the shaft 79. The first of the series of rollers 108 is provided with
a sprocket wheel for receiving the chain, and is connected with the outer rollers in
the series by a chain gearing.
The operation of my improved machine is as follows:
The melted glue being delivered by the valve 7 to the cylinders 8, is spread out
and formed into a thin sheet and cooled as it is carried forward by the cylinders, the
said cylinders being cooled by the passage of cold water through them, or the
application of cold water to the under surface of the cylinders, as described in
the application for a patent to which reference has been made. The cooled sheet
of glue is delivered to the endless conveyer 9, which in turn delivers it to the series
of cords 18, which carry it forward over the drum 21, where it is cut into lengths
by the knives 25. As soon as the sheet of glue comes above the table 62, the said
table is raised by the chains 50, 54, lifting the sheet of glue from the cords 18; the

page_text: continued forward movement of the said chains 50, 54, carries the table rapidly
forward, at the same time tilting it so as to compel it to take a position parallel with
the cords 19. When the table is dropped it leaves the sheet of glue upon the
cords 19. The said cords 19 move forward with a velocity which is greater than
the velocity of the cords 18, thereby causing the sheet of glue to advance sufficiently
to leave a space of six or eight inches between the sheet deposited and the next
succeeding sheet. The table 62, after being dropped is quickly returned to its
position at the receiving end of the machine, while in the meantime another sheet
of glue has been carried forward into position to be taken by the table and carried
forward to the cords 19, as before described. By carrying forward the sheet of
glue from the cords 18 to the cords 19, and increasing the speed of its travel on
the cords 19, sufficient space is left between the sheets to allow for spaces between
the nets, the spacing being governed by the thickness of the net frames, also by the
distance required between the nets, to allow for the operation of the net stacker.
The sheet of glue is carried forward by the cords 19 underneath the revolving
cutters 39, which divide it into strips of suitable width, and the said strips are
moved forward and delivered to the cords 71. In the passage of the strips over the
roller 70, the said strips are cut up into suitable lengths by the knives 69, and the
sheet of glue thus sub-divided is carried forward by the cords 71, to the roller 72,
where it is delivered to the net 80. While the sheet of glue is being formed, cut
into sheets, spaced, cut into strips, and further sub-divided by being cut into small
squares preparatory to its delivery to the net frames, and the frames having been
placed in the form of a stack above the unstacking mechanism, the net frames 80
are delivered one by one to the endless chain 74, by the unstacking mechanism 3,
which operates as follows: The stack of frames being held by the pawls 83, to
engage the lower frame of the stack, the bars 91, are lifted by the cams 97. As
the said bars 91 come into contact with the under surface of the lower frame, the
trippers 90 engage the arms 89, thus turning the rock shaft 87, and through the
movement of the arms 86, withdrawing the spring pressed rods 84" from the pawls 83,
allowing the weights 84 to tilt the pawls and disengage them from the net frames 80,
as the weight of the net is taken from the pawls by the bars 91. The continued
movements of the cams 97 allow the bars 91 to descend, thus lowering the entire
stack of net frames, and at the same time releasing the arms 89, 86, allowing the
spring-pressed rods 84 to move forward against the pawls 83, so that when the
second frame from the bottom of the stack reaches the pawls, the said pawls engage
the notches in the frame and support the entire stack. The lower net frame of the
stack being below the device, continues its descent until it rests upon the endless
chains 74, which move the frame forward from beneath the stack of frames, so as to
permit of another excursion of the bars 91.
The chains 74 and the intermittent unstacking mechanism, are timed with :
reference to each other and to the delivery of the sheet from the sheet separator
and sub-divider so that the cords 71, may deliver a sub-divided sheet of glue to a
net 80 as it passes under the roller 72, the required intermittent motion of the
unstacking mechanism being secured by the segmental pinion 99 and wheel 100, the
said wheels being connected with the same source of power that operates the other
portions of the machine.
The frames after being filled are still carried forward until arrested by the
posts 74, when they are received by the bars 91 of the stacking mechanism,
which correspond to the bars 91 of the unstacking mechanism at the opposite end
of the machine, while the said bars are in their lowest position, and the said bars
are raised by the cam 97* in the manner above described, lifting the net frame 80
from the chain 74, carrying upward with the said frame the superposed frames,
until it is brought into engagement with the pawls 107, thus adding one frame
after another to the bottom of the stack until a stack is formed of convenient size
for handling.
The height of the stack is controlled by the gearing connected with the endless

page_text: chain 119. The said gearing takes its motion from some moving part of the
machinery or from the source of power, and is timed so as to work synchronously
with the unstacker, and the separator and sub-divider. The chain 119 is moved
forward intermittently by the segmental wheel 124, the segmental pinion 123, the
spur wheel 122, pinion 121, and sprocket wheel 118. The bars 120 connected with
the chains 119 on opposite sides of the machine, engage the stack of net frames 80,
and move it forward over the rollers 108, until it is engaged by the power-driven
rollers 108, which carry it away from the delivery end of the machine to be
transferred to the drying room.
Although I have described my improvement as consisting of a glue cooler, a sub-
divider and spacer, a net unstacker and a net stacker, I do net confine myself to
this arrangement, as the unstacker and the sub-divider and spacer may be omitted
and the glue may be delivered directly to the nets carried by the endless chains, and
the nets may be stacked in the manner already described.
