PROVISIONAL SPECIFICATION,
Improvements in Machinery for Mechanically Introducing Pressing
Boards into the Folds of Fabrics and the like."
I, GUSTAV ADOLF SCHULZE of No. 12 Johannisstr. Dresden, Saxony, in the
Empire of Germany, Engineer, do hereby declare the nature of my said invention
to be as follows;-
My invention relates to a machine for mechanically inserting pressing boards
by means of pneumatic sucking cups, the special object of the invention being
to attain that the sucking devices which are intended for holding and lifting the
said pressing boards after such devices have been pressed upon the smooth surfaco
of the boards, are regulated mechanically by reason of their air inlet openings
being covered tightly in the first case or uncovered, in the second caso.
In so far this invention differs from all other similar machines with sucking
devices consisting of rubber cups, as in the latter these cups must be torn from the
bourds in order that they may release the same, which of course spoils the same
when this has to occur often.
As to the mechanical construction of the machine there is another important
point consisting in that all motions aro derived from the reciprocating motion of
a slide carrying the feeling device for the goods and moving the suction cups
alternately over the gradually sinking pressing table (follower) and the adjoining
staple of pressing boards.
Before further describing the construction of this machine it may be recom-
mendable to describe the pressing table (follower) and the adjoining staple carry-
ing tables, although the same do not form part of the invention, these constructions
being known in other similar machines.
The stock of pressing boards is placed upon the feeding tables at the right and.
at the left side of the table, where the laying between is done. As one pressing
board is taken away alternately from the right and then from the left pile and
the upper pressing board at both sides must always present itself at the edge of
the table ready for being laid between, both stock carrying tables must be raised
gradually at the same ratio as the pressing boards are removed and the table where
the laying between is done, must of course be sunk in proportion to the piling up.
of the boards.
This raising and sinking of the tables can be caused by means of screws in com-
bination with some intermediate device, the arrangement of which needs no
description.
The sliding carriage is fed along a dove tailed guide upon the frame surrounding
the central pressing table and the lateral stock tables and a reciprocating motion
is imparted to the same by means of a special gearing device.
Two connecting rails or bars between the cheeks or sides of the sliding carriage
serve for carrying the suction cups or rubber funnels and bear upon a horizontal
and vortical guide; a shaft mounted in eyes and a rod supported upon forked
pieces are located above the rails.

page_text: The adjustable prossing devices are attached to the rod; they are depressed by
springs and are provided at the bottom with rubber discs having for object to shub
off the upper, open extremity of the rubber funnel as soon as the air has sufficiently
been driven out of the same by their being pressed upon the pressing board, in order
to prevent the same from entering again the funnels.
When the rubber funnel must release its grip on the pressing board, the rod
is raised, the rubber discs are taken away from the rubber funnel and the air can
enter the funnel so that the pressing board can fall down leaving the rubber
funnel.
This upward movement of the rod is produced by the cams which are formed
by the bent down extremities of the rods striking against the projections of the
frame so that by means of an arresting of the motion of the rods and by reversing
the lever, the rod moves upwards. The motion is transmitted from levers, which
bear upon shafts, upon the extremities of the rod, bearing on same, by means of
annular lever arms. A rotatory lever is arranged inside the sliding carriage, the
end of which, that is directed towards the centre of the machine, passes over the
rail and whose other extremity carries a lever arm, which is provided with a roller
in order that when the sliding carriage runs back it shall run
an inclined plane and shall depress the rod, which carries the rubber
funnel in the guide, whereby the air will be driven out through the
upper opening of the funnel and the said funnel will hold the press-
ing boards as a consequence of the fact that the air cannot penetrate therein
any more. When the roller of the lover arm has passed over the inclined plane,
a spring pulls the entire mechanism upward again.
upon
While the pressing board is caught by the rubber funnel, the guide strip strikes
a projection whereby the entire mechanism is stopped until the sliding carriage
returns and carries along the eutire mechanism together with the pressing board
by means of a projection.
The pedestal of the feeding mechanism of the fabric is arranged upon the sliding
carriage; ia this mechanism, cylinders are arranged, which feed the required
longth of the fabric into the machine and eventually take out the folds that may
exist therein.
A powerful spiral spring is placed in the pulley frame; one of its extremities is
fixed to the pivot of the cylinder, the other is fixed inside a frame; this spring
winds up again the strap or chain, when the machine retires.
The spring casing and pawl are rotatably journalled upon the pivot of the
cylinder while a pinion is rigidly connected with the pivot of the cylinder.
The downward moving fabric can be stretched according to requirements by a
lever with guide roller provided with a counterweight.
At the other side or under this arrangement, there is a movable forked rod or a
slitted flat iron rod which reaches cross ways through the machine by which
device, which is inserted between the layers of fabric in connection with adjustablo
brush rollers, the forming of folds can be prevented, by a simple turning of the
same.
The guide rollers are journaled flexibly or put under the action of springs at
the side of the sliding carriage or of the pedestal and as soon as they come over
the central table they roll over the inclined plane, whereby a rising is produced
in order not to strike against a partition of the frame and not hold on to the press-
ing board.
At each end of the sliding carriage, a rod bears flexibly in a horizontal and vertical
guide in order to press down the pressing board by the folding down of the fabric,
when the sliding carriage retires whereby the entire butt surface lies against the
partition. The upper connecting bar which is held up by a spring and a support
and is connected with a bar by means of springs, carries at its side an arm which is
provided with a spring to which a tapering pin is attached which when the sliding
carriage is in forward motion, slides over the inclined plane and when the same

page_text: retires passes downwards of the inclined plane whereby the entire machine drops
and presses upon the upper pressing board.
In order to prevent the upper fold or layer of fabric from being lifted by the
tightening of the stretching rollers, I have provided hooks, which are turned in-
side, into the partition of the machine by means of levers as soon as the stretching
rollers are at a determined distance and the inclined plane presses a lever out-
wards.
.
In order that the rubber funnels can carry along only one pressing board, I
have provided springs, the upper end of which is measured in such a manner that
only one pressing board can pass.
The same object may be attained by arranging brushes near the points tho
suction cups are coming in contact with the boards.
The machine works as follows:-
The sliding carriage moves until the pressing board which has been caught by
the rubber funnel has reached the place it must occupy. Before the sliding
carriage has reached its extreme position to the left, the inclined plano attached
to the same has taken position behind a lever, whereby the latter is pulled out-
side, the hooks supporting the pressing board are turned around a lever so thab
they take position in a partition, releasing the pressing board resting upon the
same so that it can fall downwards.
The fabric which runs around a cylinder covers this pressing board and a board
held by the rubber funnels takes again its position above the fabric.
A cam fixed to the sliding carriage strikes a projection, whereby, a rod is
released and driven upwards while the upper ends of the rubber funnels open and
let the air penetrate, whereby the pressing board is released, its front extremity
taking position upon the upper layer or fold of the fabric and its other extremity
upon a hook.
During the operation just described, the left part of the sliding carriage has of
course also moved in a certain direction, a guide strikes against a projection, the
apparatus to which the rubber funnels are fixed is held stationary, while the sliding
carriage continues its course, a lever through the intermediary of another lever
with roller runs over an inclined plane, pressing the apparatus with the rubber
funnels down upon the top pressing board, the air escapes out of the funnel, a
vacuum is established in the same and when the roller of the said lever leaves the
inclined plane, a spring lifts the rubber funnel and the pressing board attached
thereto by suction and the motion in the other direction can commence.
During the forward motion the fabric is folded around the just inserted press-
ing board, hooks are turned by a spring so as to be parallel again with the
longitudinal axle of the machine in order to maintain in position the upper fold
or layer of fabric, or to prevent that the latter be lifted by the pulling of said
fabric. A pulling out of the upper pressing board is made impossible by a rod
depressing the said board by its downward motion, thus tightening the same
against the partition.
The winding off of the fabric from the cylinder upon which it is wound, is
effected by means of rollers; the latter are connected with the frame by belts,
such frame being fixed upon a spring box, winding up and keeping tight the belts
as soon as they are no longer tightened by the motion of the sliding carriage.
When the sliding carriage moves one of the belts unwinds from the spring box
and the latter rotates..
A pawl fixed to the spring box catches in a rack wheel arranged upon the pivot
of the cylinder and thereby actuates the cylinder while the other belt is wound
up by the spring box. The feeding of the fubric is regulated in any suitable
manner.

Boards into the Folds of Fabrics and the like.",
I, GUSTAV ADOLF SCHULZE of No. 12 Johannisstrasse, Dresden, Saxony, in tho
Empire of Germany, Engineer, do hereby declare the nature of my said invon-
tion and in what manner the same is to be performed, to be particularly described!
and ascertained in and by the following statement:-
My invention relates to a machine for mechanically inserting pressing boards
by means of pneumatic sucking cups and the feature thereof is that the sucking
devices which are intended for holding and lifting the said pressing boards, after
they have been pressed upon their smooth surface, are regulated mechanically
by reason of their air inlet openings being covered tightly in the first case or
uncovered in the second case. In so far this invention differs from all other
similar machines with sucking devices consisting of rubber cups, as in the latter
these cups must be torn from the boards in order that they may release the same,
which of course spoils the same when this has to occur often.
In regard to the mechanical construction there is another important point con-
sisting in that all motions are derived from the feeding apparatus for the goods
and the suction cups that convey the same over the gradually sunk pressing table
(follower) and the adjoining staple of pressing boards.
In the accompanying drawings:
Figure 1 shews a longitudinal sectional view of the upper essential parts of the
machine for laying in pressing boards, the mechanisms for gradually sinking the
table and for gradually raising the staple of pressing boards being omitted.

Figure 9 is partly a section and partly a side elevation similar to Figure 2, on
the line of Figure 1.

of the sinking cups.
Figure 11 is a section on the line 2-z of Figure 9, and
Figure 12 is a section on the line y-y of Figure 9.
Before speaking further of the construction of this apparatus itself I will describe
the pressing table (follower) and the adjoining staple carrying tables although
the same do not form part of my present invention, such apparatus being known
in other similar machines.
In Figure 1 only the essential parts of the machine are actually shewn and the
table slab A. upon which the pressing board is introduced between the goods and
which must gradually be sunk in proportion to the number of inserted boards as
well as the plates supporting the stock of pressing boards or feeding tables A' A'
are iudicated only by dotted lines. The stock of pressing boards 14 is placed
upon the latter at the right and at the left side of the table where the laying
between is done. As one pressing board is taken away alternately from the right
and then from the left pile and the upper pressing board at both sides must always

page_text: present itself at the edge of the table ready for being laid between, both stock
carrying tables A', A must be raised gradually, at the same ratio as the pressing
boards are removed, and the table A where the laying between is done must of
course be sunk in proportion to the piling up of the boards.
This raising and sinking of the tables can occur by means of screws, a, a, a³,
(partly shown in Figure 1) in combination with some intermediate dovice, the
arrangement of which need not be described as it does not form part of my present
invention.
The carriage is provided with sliding shoes 1 engaging slate P' arranged in
the frame or in mils which are carried by same (Figure 9).
The carriage 1 may reciprocate in the longitudinal direction of the frame P.
This is effected for instance by means of a crank driven by a pulley or the like
mounted in the frame of the machine, such crank being connected by means of
lever mechanism with an eye or a rod at one end of the carriage in such manner
that on every full revolution of the crank a reciprocating motion is imparted to
the carriage.
The device for operating the carriage is, however, of no moment for the present
invention and is therefore not shown in the drawings; such device may of course
be substituted by any suitable arrangement without departing from the spirit of
the invention.
The two connecting bars or rails 2 and 3 between the cheeks or sides of the
sliding carriage serve for carrying the suction cups or rubber funnels 13, and
are slidably mounted in slots of a horizontal guide piece 4 or 5 and of a vertical
guide piece 6 or 7 (Figure 12); a shaft 8 or 9 is journalled in the eyes 78
(Figure 9) of the bars or rods 2 or 3 and a rod 10 is slidably mounted in pieces 11
which project from the rails 2 and 3.
The pieces 12 are adjustably attached to the rod 10 (Figures 2, 9 and 11) and
serve for alternately tightening and releasing the openings of the sucking cups 13;
they are normally depressed by the springs 23 whose ends are secured to the
rods 10 and the rods 2 and 3 respectively, (Figure 9).
The pieces 12 are provided at the bottom with rubber discs 83 (Figure 11)
whose object is to shut off the upper open extremity of the rubber funnels as soon
as the air has been driven sufliciently out of the same by their being pressed upon
the pressing board, in order to prevent the same flowing into the funnels again.
When the rubber funnels 13 (a detailed section of one of which is shown in
Figure 7) are required to release their grip on the pressing board the rod 10 is
raised, the rubber discs 83 are taken away from the rubber funnels and the air can
enter the funnels so that the pressing board 14 can fall down, leaving the rubber
funnel 13. For raising the rod 10 and pieces 12, the former is connected with
arms of the swinging shaft 8 or 9.
This upward movement of the rod 10 is produced by the hooks or projections 16
and 18 which are formed by the bent down extremities of the rods 16 aud 17 and
strike against the projections 19 and 20 of the frame, so that by means of an
arresting of the motion of the rods 15 or 17 and by reversing the lever 21 or 22
the rod 10 must move upwards. The motion is transmitted from the levers, 21, 22,
(Figure 1) which bear upon the shafts 8, 9, (Figures 1 and 10) upon the extremities
A lever,
of the rod 10, bearing over the same, by means of angular lever arms.
25 or 26, is hinged to the carriage 1 (Figure 1), one end of such lever being
directed towards the centre of the machine and engaging in a slot of the rail 2 or 3,
and the other extremity carrying a hinged lever arm 27 or 28, provided with a
roller, in order that when the sliding carriage runs back such roller shall run
upon the inclined plane 29, 30 so that the lever 25 or 26 shall depress the corre
sponding rod 2 or 3 which carries the rubber funnels 13, whereby the air will be
driven out through the upper openings 24 of the funnels 13, and the said funnels
will hold the pressing board as a consequence of the fact that the air cannot
penetrate therein any more, as has been herein before described. As soon as tho

page_text: roller of the acting lever arm 27 or 28 leaves the corresponding plane 29 or 30
on the return of the carriage 1, a spring 31 or 32 (Figures 1 and 12) which is
attached to one of the rods 2 or 3 is actuated and raises the latter when the arın 27
or 28 passes from the corresponding plane 29 or 30.
In order that the carriage after the suction cups have been pressed upon the
pressing board in the above described manner by the co-operation of the arms 27, 28
with the inclined planes 29, 30, may continue or complete its stroke without carry-
ing the suction cups along, the horizontal guides 4, 6 are provided for the rods 2
and 3 respectively which strike against the projections 33, 34 whereby they are
brought to a standstill, the horizontal guides 4, 5 allowing the carriage 1 to con-
tinue its course.
By means of the projection 33 or 34 the rod 2 or 3 co-operating with the latter,
is secured until the carriage 1, after having completed its stroke, returns, and by
means of the projection 35 or 36 carries along the rod 2 or 3 and the suction cups
which are carried by same and now adhere to the pressing hoard.
The pedestal 37 of the feeding mechanism of the fabric 82 is arranged upon
the sliding carriage; in this mechanism cylinders 38 and 39 are arranged which.
feed the required length of the fabric into the machine and eventually take out
the folds that may exist therein. When the sliding carriage moves in the
direction of the arrow (Figure 1), there will be seen from the diagrammatical
Figure 8 that the oylinders 38 and 39 will be put in rotary motion by means of a
strap or chain 40 wound around the tackles 41, whereby the material is fed to the
central tables.
A powerful spiral spring 42 is placed in the pulley frame 41; one of its
extremities is fixed to the pivot of the cylinder 39, the other is fixed inside the
frame 41; this spring winds up again the strap or chain 40 when the previously
operated parts of the machine return. The spring casing 41 is provided with a
pawl 43 and is rotatably jourualled upon the axle of the cylinder 38 or 39
(Figures 2, 3 and 8) while the rack wheel 44 is rigidly mounted on the axle of the
cylinder. The downward moving fabric can be stretched according to require-
ments by lever 45 which is provided with a guide roller and a counterweight.
The spring-actuated guide rollers 47 and 48 are journalled at the side of the
sliding carriage I or of the pedestal 37 and as soon as they pass beyond the central
table they roll upon the inclined plane 19 or 20 in order that they may be prevented
from abutting against the partition 49 or 50 of the frame. The guide rollers are
adapted to stretch the fabric upon the table slab and to adjust the position of the
fubric whose surface may occasionally be situated too high or too low in con-
sequence of the variety of thickness of the fabric.
At each end of the sliding carriage I a spring actuated rod 51, 52 is mounted in
a displaceable horizontal and vertical guide 53 and 54, or 55 and 56 in order to
press down the pressing board when the sliding carriage retires. The upper con-
necting bar 57 which is held up by the spring 58 or 59 attached to the support 60
or 61 and is connected with the bar 51 or 52, by means of springs 62 and 63 or 64
and 65, carries at its side an arm 66 (Figure 4) which is provided with a plate
spring 67 to which a tapering pin 68 is attached which when the carriage is in
forward motion, slides over the inclined plane 69 and on its return passes below
the inclined plane 69 (Figure 5) whereby the rod 51 or 52 is depressed upon the
upper pressing board.
This downward movement of the rod 51 or 52 is effected every time shortly
before the completion of a stroke. of the carriage 1 and is adapted to secure that
free end of the uppermost pressing board which has just been released by the
suction cups and dropped upon the fabric and to avoid a raising of the same by
the pressure of the rollers 47, 48 which are operated directly afterwards. The
releasing of the rod 51 or 52 is effected by the springs 62 or 65 as soon as the
pin 68 which, as already mentioned, slides on the lower plane of the projection 69
provided on the frame of the machine, is released after passing over the edge of
the inclined plane.

page_text: The pin 68 is now drawn upwards by the spring 58 or 59 whereupon the rod 51
or 52 is also raised from the pressing board by the spring 62 or 65.
During the low position of the rod 51 or 52 the same is preferably secured so
as to prevent the pressing board from being damaged through friction. This may
be effected for instance by projections on the inclined planes 19 and 20 respec-
tively, the arrangement of these projections is however not claimed as part of the
invention and it is therefore not necessary to fully describe same.
The carriage is allowed to continue its course by reason of the horizontal
guide 53 or 55 in which the rod 51 or 52 slides.
In order to prevent the upper fold or layer of fabric 70 from being raised when
the stretching rollers 47, 48, are actuated, I have provided hooks 71 or 72 which
are turned inside, by means of the levers 74, 75, 76 and 77 as soon as the stretching
rollers 47, 48 are at a determined distance; this is effected by an inclined plano 73
which presses the levers 76 and 77 outwards.
In order that the rubber funnels 13 can carry along only one pressing board.
I have provided the springs 80.
The operation of the machine is as follows;-
The sliding carringe I moves in the direction of the arrow (Figure 1) until the
pressing board which has previously been caught by the rubber funnels 13 situated
on the right has reached the place it must occupy over the table slab. Before the
sliding carriage reaches its extreme position to the left, the inclined plane 73
attached to the same is moved beyond the lever 77 on the left whereby this lever
is pulled outside and the hooks 71 on the left are turned at an angle of 45° so that
the pressing board still resting upon same is released and can fall downward. The
fabric which passes round the cylinder 48 covers the pressing board which has
dropped below and another board 14 is now suspended above the fabric by the
rubber funnels 13 on the right. The hook or projection 18 fixed to the lever 17 on the
right strikes the projection 20, whereby the rod 10 situated on the right is released
and driven upwards by means of the lever 22 so that the upper ends of the rubber
funnels 13 on the right are uncovered and let the air penetrate, whereby the press-
ing board which was hitherto held by those funnels is released, its front extremity
tuking position upon the upper layer or fold of the fabric and its other extremity
upon the hooks 72. During the operation just described the left part of the sliding
carriage has of course also moved in the direction of the arrow (Figure 1) the rod 2
strikes against the projection 33 so that the mechanism which carries the rubber
funnels 13 situated on the left is arrested, whereas the carriage continues its
The roller of the lever 27 passes upon the inclined plane 29, whereby
the lever 27 is depressed and the rubber funnels on the left are lowered upon the
top pressing board of the left hand pile. The air having previously escaped out
of these funnels a vacuum is established in the same. On the movement of the
carriage being reversed the roller of the lever 27 now returns from the inclined
plane 29, the spring 31 raises the left hand rod 2 and the corresponding rubber
funnels and a pressing board is attached thereto by suction. Whilst the carriage
is moving to the right the fabric is folded around the just inserted pressing
board 14, the hooks 71 are turned back by the left hand spring 84 so as to be
parallel again with the fabric in order to maintain in position the upper fold or
layer of fabric for proventing tho latter from being lifted by the stretching of said
fabric. A pulling out of the upper pressing board is made impossible in such
manner that the rod 52 dopresses the said board by its downward motion and thus
tightens the same against the partition.
course.
Just before the end of the stroke in the direction from left to right, the cam 16
of the rod 15 strikes against the cam 19 and operates the lever 21 in such manner
that the rod 10 on the left is raised with the pressers 11 connected thereto; the
admission of the air through the openings 24 of the suction cups is thus enabled
and such openings allow the pressing board to immediately drop upon the layer
of fabric which was last stretched over the table slab.
It is obvious that from the foregoing that the parts on both sides of the carriage

page_text: mutually work together. The tearing hitherto caused through rubbing against
the pressing board is avoided by the present invention so that tho pressing board
is pressed and may be used for a long time.
The winding off of the fabric from the cylinder upon which it is wound is
effected by means of the rollers 38 and 39; the latter are connected with the frame
by the belt 40 which are fixed upon spring boxes 41, which by means of the
springs 42 contained therein, wind up and keep tight the belts 40 as soon as they
are not tightened any more by the notion of the sliding carriage.
When the sliding carriage moves, one of the belts unwinds from its spring box
and the latter rotates, the pawl 43 fixed to the spring box catches in the rack
wheel 44 arranged upon the pivot of the cylinder and thereby actuates the cylinder,
while the other belt is wound up by the spring box. The feeding of the fabrio
is regulated by means of adjustable stops 79 which are attached to the belts and
engage with shoulders or projections 81 of the frame.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
1/ A feeding apparatus for machines for inserting pressing boards characterized
by suction cups 13 provided with air inlets 24 the former being regulated mechani-
cally and arranged in a double row operating alternately and being moved over
the staple of pressing boards near the folding table, and depressed by a stopping
device, while at the same time the upper air inlet openings of the said cups are
shut off in such manner that they do not let go the pressing board caught by the
same before the presser rod 10 moves in the direction causing said openings to
be uncovered, substantially as described and shown in the drawings.
2/ In combination in pressing board feeding apparatus, a mechanism for
periodically lowering the springy suction cups characterized by levers, 25, 26
journalled to the sliding carriage having hinged arms 27, 28 that can be bent
down outwardly, caused to operate the lever at the moment of the change of stroke,
by means of inclined projections 29, 30 while a stopping device for the suction
cups, being displaceable in the guides 6, 7 is operated by the striking thereof
against the projections 33, 34 while allowing the sliding carriage to continue its
course, substantially as described and shown in the drawing.
3/ In combination with the pressing board feeding apparatus described in
claim I, an arrangement having for its object to keep down the plaits of fabric,
consisting of overlapping hooks 71, 72 rotatable in a horizontal direction, extend-
ing over the edges of the plaits and turned out of the way in order to let drop the
next above pressing board while in order to prevent the inserted pressing boards
from jumping out, pressing rods 51, 52 are arranged which hold down said press-
ing board while yet resting upon the overlapping hook, substantially as described
and shown in the drawing.
4/ In combination with the sliding carriage and means for taking up and
releasing the presser boards means adapted to make the unwinding of the fabriq
or the feeding thereof keep pace with the motion of the sliding carriage
characterized thereby that the feeding cylinders 47, 48 carried along by the sliding
carriage I in its reciprocating motion and provided with locking spring boxes 41
assumes alternately the motion of these spring boxes by means of connecting means
winding up around and unwinding from said spring boxes, substantially as
described and shown in the drawing.
