DEVICE FOR INTERLEAVING SHEliilTS Application filed July 30,
To all whom it may concern:
Be it known that I, CARL lVINKLER, a citizen of the Swiss Republic, residing at Berne, in the Swiss Republic, have invented a new and useful Improved Device for Interleaving Sheets Printed in Cylinder-Flat-Bed Machines (for which I have filed applications in Germany February 6, 1920; bwitzerland January 20, 1921; France February 28, D21; Austria February 4, 1921, and Czecho-Slovakia February 15, 1921,) of which the following is a specification.
In an existing device for interleaving sheets printed in cylinder-flat-bed machines grippers are provided on the delivery apparatus for taking up a sheet from a pile situated between the impression cylinder and delivery table and carrying said sheet forward simultaneously with the printed sheet. This device however requires special sup ports for the interleaves and a second series of grippers for keeping back each interleaf during the return movement of the first series of grippers, and these requirements render the machine more complicated. A great drawback of this device consists, further, in the fact that it can only be used for cylinder-flat-bed machines of the kind, in which the feed and delivery tables are situated at difl'erent ends of the machine, because in other types of machines there is no accommodation for the pile of interleaves.
y invention relates to a device for interleaving printed sheets which does not possess the above cited drawbacks. The inter-leaves are taken by hand from a pile provided he hind the cylinder-flat-bed machine and placed in the reach of grippers provided on the delivery device and adapted to carry forward each said sheet and let it fall on the printed sheet whilst this latter is falling on the delivery table.
This device is characterized by great simplicity and can be used with all machines having the front delivery construction no matter whether the delivery table is at the front or back end of the machine.
When it is desired to work without interleaving the pile table at the end of the ma chine and the bridging piece for supporting the sheets when fed forward by hand are removed, and the machine is then ready for printing.
In the drawing representing my invention by way of example,
Fig. 1 is a side elevation of the delivery PRINTED CYLINDER-FLAT-BED MACHINES.

mechanism in which are provided the grippers for taking up the interleaving sheets,
Fig. 2 is a section through the delivery mechanism and grippers shown in Fig. 1,
Fig. 3 a part plan, and Fig. 1 a back elevation of the device shown in Figs. 1 and 2,
Fig. 5 shows diagrammatically how an interleaf is led over the freshly printed sheet.
The carriage a is moved backwards and forwards by the chain Z), being guided by rolls 0 and rails d. From two such carriages provided on opposite sides of the machine the transport spindle e is carried, over which pass the endless tapes j", by which the printed sheets are allowed to fall on the table 9. The carriages a also carry the transverse rod it, on which are fastened the grippers i and a lever is, carrying a roller Z, which at each end of the stroke of the carriage a strike against an inclined tappet m or m on the frame a and thus open the grippers i which are normally pressed by the spring 0 against the bar p connecting the two carriages a. When the opened grippers are in the right end position (Fig. 1) an interleaving sheet is fed by hand between the grippers and bar 7). As soon as the carriages a have returned towards the left to such an extent that the roller Z leaves the tappet m, the grippers z are closed by the spring 0 and carry said sheet forward until the grippers 2', owing to the roller Z coming into contact with the tappet m, are opened again. The interleaf being new free can fall on the freshly printed sheet, which is being simultaneously allowed to fall on the table 9 by the tapes 7 and transport spindle 6.
Between the feed bar p and the pile table 9 there is a bridge piece 1 which supports the interleaving sheets when pushed forward by hand.
WVhat I claim and desire to secure by Letters Patent of the United States is 2-- l. A device for interleaving sheets printed in cylinder-flatbed machines, comprising, in combination with a reciprocation delivery device, normally closed grippers adapted to move backwards and forwards with said delivery device, a portable pile table for interleaving sheets provided just outside the range of said reciprocating delivery device, and tappets to open said grippers at the ends of the backward and forward strokes of said delivery device, substantially as, and for the purpose, set forth.
2. A device for interleaving sheets in cylinder-flat-bed machines, a frame, a reciproeating carriage mounted on the frame, a rod mounted to rock in the carriage, spring pressed grippers carried by the rod and coacting with a member of the carriage, tappets secured to the opposite ends of the frame in the line of movement of the carriage, and a lever on the gripper carrying rod and adapted to engage the tappets at the ends of the backward and forward movements of the 10 carriage to open the said grippers.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
C. WINKLER.
