DELIVERY APPARATUS FOR PRINTING-MACHINES.
SPECIFICATION forming part of Letters Patent No. 232,203, dated September 14, 1880.
Application filed June .25, 1880. (No model.)
To all whom it may concern Be it known that I, CHARLES Po'r'rnn, Jr., of Plainfleld, in the county of Union and State of New Jersey, have invented an Improve ment in Delivery Apparatus for Printing- Presses, of which the tollowing is a specification.
3efore my present invention an impressioncylinder had been employed with a flat reciprocating type-bed, and a delivery--cylin(ler having gripers to seize the advancing edge of the printed sheet had taken the sheet from the impressioncylinder and delivered it upon ranges of inclined belts, that conveyed the sheet along over the fly to near the base of said fly, in order that the fly might lift the sheet 0d" the tapes and carry it over and lay the sheet on the pile of sheets. In this case the impression is liable to become blurred, because the fly acts to lift the sheet 0d" the belts, and the two forces are actingpositively on the sheet, and all parts thereof are not entirely clear of the tapes before the fly has stopped the endwise movement of the sheet, or else the sheet is still moved endwise by the tapes after it touches on portions of the fly-fingers.
In other instances the sheets have been delivered to a cylinder by bolts, and from that they have passed vertically, or nearly so, to the fly. In these instances the printed sheet passed between belts and was liable to be blurred.
In my improvement I combine with the impression-cylinder, having gripers for the sheet, a second or delivery cylinder having gripers; and a range of belts and pulleys, to which the belts pass nearly horizontally, and a fly the upper ends of whose fingers pass in between the pulleys, and a stationary deflector, beneath which the sheet passes, and from which it receives a downward direction to cause it to pass in front of the fly. By this arrangement the printed sheet simply lies upon thebelts while being conveyed along, and there is no risk of the impression being injured.
In the drawing 1 have represented my improvement by a vertical section.
The bed a, impressioncylinder b, deliverycylinder 0, gripers d, and range of endless 5o belts 0 are the same as heretofore usually employed, except that the pulleys f, for the endso, and a contact-roller at l insures the passage of the sheet upon the nearly horizontal tapes after the gripers (l have let go of the advancin g edge.
If the sheet were allowed to move by the action of the belts alone, the inertia-and the atmosphere would tend to carry the sheet out nearly level from the pulley f, and the sheet would fall in a shapeless mass. To avoid this difliculty I make use of a segmental deflector,
a, that is adjacent to the pulleys f, so that the sheet, as its advancing end passes beneath this deflector, is directed downwardly,andits course is changed from a horizontal to a perpendicular direction, and I find that the air intervenin g between the deflector and the printed sheet 7 5 prevents the first impression being blurred, the last impression being next to the tapes.
It will now be evident that the printed sheet passes vertically down in front of the fly, and
hence that it is entirely clear of the tapes at the time that the fly acts upon the same and arrests its downward movement, and carries it in the are of a circle and deposits it upon the pile of printed sheets.
I claim as my invention- In combination with the impression cylinder and its gripers, a delivery-cylinder having gripcrs to take the sheet from the impressioncylinder, a range of belts around the deliverycylinder, and the distant range of pulleys for 0 such belts, whereby the sheet is conveyed horizontally, or nearly so, a fly the upper ends of whose fingers pass in between the pulleys, and a stationary deflector to give to the sheet a vertical direction in front of the fly, substan- 5 tially as set forth.
Signed by me this 22d day of June, A. D. 1880.
