Improvements in and connected with Machines for Inserting
Pressing Boards or Sheets Between the Folds of Cloth or
other Fabrio.
I GEORG SOBLEBER of the Firm of Georg Schleber Färbereien and Approtur-
Anstalten Actien Gesellschaft of Greiz in the Empire of Germany Dyors and
Finishers do hereby declare the nature of this invention and in what mannor the
same is to be performed, to be particularly described and ascertained in and by
the following statement :—
This invention relates to what are known as pressing boad machines for folding
cloth.
Now it has been found in practice that pressing board machines as at present
constructed are apt to deliver more than one board at a time owing to the boards
sticking together, and the object of this invention is to prevent more than one
board from being lifted at once which object I attain by arranging at each end of
the machine a pair of brushes which brushes prevent the suckers from lifting more
than one board (namely the uppermost at each reciprocation of the machine, as
should two or more boards stick together the brushes will detach all the boards not
wanted from the underside of the board attached to the suckers.
And in order that my said invention may be fully understood I will proceed
to explain the same with reference to the accompanying sheet of drawings in
which
Fig. 1. represents sectional elevation of an apparatus constructed according to
this invention.
Fig. 2. shews lifting apparatus to an enlarged scale the suckers just having
released a board.
Fig. 3. shews lifting apparatus in the act of raising a board,
Fig. 4. is a cross section on line Fig. 1. ahewing suckers raised.

Fig. 5. is a cross section on line Fig. 1 shewing suckers raising a board.
The same letters denote the same parts in all the ligs.
Now according to this invention 1 provide a table on which is mounted the
carriage c for inserting pressing boards or sheets between the folds of cloth or other
fabric under treatment.
The carriage c is provided with two sets of suckers which lift the boards or
plates by suction and carry the lifted board over the fold of cloth or other fabric
and when the said board is vertically over the said cloth the board is released by
admitting air to the inside of the suckers.
The lifting apparatus is constructed as follows ee aro pieces of metal or other
suitable material attached to the carriage c. The pieces e are provided with
grooves d d in which move vertically crossheads ff which crossheads are attached
to the ends of the cross bar g. Any suitable number of cups or suckers h¹ made of
indiarubber or other suitable material are attached to the crossbar g the suckers h¹
are provided with hollow necks having longitudinal channels therein is a rod
having guides at each end thereof which guides move in vertical slots i.
Attached to the rod l'are as many valves as there are suckers which valves are

page_text: normally pressed on to the tops of the necks of the suckers by means of the
springs which are attached to the crossbar g and rod . These valves close the
channel in the necks of the suckers and render them air tight.
The crossbar g carrying the suckers is normally raised by means of springs m m
attached to the carriage c and to the crossheads ff by means of the brackets n n.
Levers p p oscillating about p' are provided one at each side of the machine the
long arm of the said levers are inserted in slots in the crossheads ff. The
lovers p p are forked at the end of the short arm and are fitted with tripping pienos
or catches p¹¹.
I
These lovers serve to depress the crossbar 9 and the suckers on to the stack of
boards or plates.
The valves are lifted against the pull of the springs by means of bent
lovers which are pivotted at g' to lugs formed on the crossloads f the tails of
these levers ongage with aud lift the rod 1.
111
Rods are attached to the ends of the levers q the free ends of the rods qui
being bent into a hook q as shewn at Fig. 1.
Attachments 2. 3. 5. having inclined planes theroon are secured to the table of
the machine and serve to actuate the levers P and
The action of the apparatus is as follows.
As the carriage o travels to the left (Fig. 1) the top board which is shewn
lifted by the right hand lifting apparatus will be brought over the table A on
which the cloth is folded and as soon as the board is in its proper position over the
cloth the hooked end of the rod q strikes against the attachment 5 (Fig. 2) aud
causes the lever to lift the valves and release the board which falls into
place by its own weight.
Ч
This movement of the carriage brings the suckers on the left hand side of the
machine over the stack of boards to the left and the catch p¹ of the left hand lever
will come in contact with an attachment similar to 3 the crossbar g will be depressed
and the suckers forced on to the upper board & the excess of air escaping through
the valves which close the upper orifices of the suckers the further movement of the
carriago carries the catch p past the attachment 3 and the springs m raise the
lifting apparatus and the board 2. As the board 2 rises from the stack it passes
between a pair of brushes a which detach any boards which may adhere to the
board z¹.
The motion of the carriage is now reversed and when the board &¹ is in position
over the table A the end of the rod q strikes against a stop 2 similar to that
shewn at Fig. 2 and the board is released by the opening of the valves h".
ૐ
As soon as the board 2' has dropped or simultaneously thorewith the catch p
(seo Fig. 3) of the right hand. lever p comes in contact with the attachment 3 and
depresses the suckers, as soon as the catch p" has passed the piece 3 the board is
lifted passing between the brushes a. The movement of the carriage is now
reversed and the board z placed in position and dropped and so on.
The lifting apparatus at each end of the carriage is the same so that one
description of its construction and action refers to both.
1
Having now particularly described and ascertained the nature of my said inven-
tion and in what mauner the same is to be performed I declare that what I
claim is :-
:-
1. In machines for inserting pressing boards or sheets between the folds of cloth
or other fabric the brushes a on each side of the stack of boards for the purpose
stated.
2. In machines for inserting pressing boards or sheets between the folds of cloth
or other fabric the combination with suction appliances for lifting the said boards
or sheets as hereiubefore described of brushes a on each side of the boards to be
lifted to prevent more than one board being lifted at a time substantially as
hereinbefore specified.

the accompanying drawings.
