ATN @FFEQ r1 IRVING 1 films, or PLAINFIELD, NEW JEnsiaY,
NEW YORK, N. Y., A CORPORATION or new YORK.
ASS .IGNOR To It. HOE AND 60., 0F
PRINTING-MACHINE.
To all whom it may concern:
Be it known that'I, IRVING F. NILES, a citizen of the United States, residing at Plainfield, county of Union, and State of New Jersey, have invented certain new and useful Improvements in Printing Machmes, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.
This invention relates to improvements in printing machines.
Transfer printing machines as now ordinarily constructed employ three cyllnders, said cylinders being arranged to make turn for turn with each other. Where it is desired to use a fiat sheet delivery with such cylinders, a traveling sheet carrier, such, for
material.
Instance, as chains provided with grippers,
is located beneath the impression cylinder.
In the operation of this mechanism, the sheet is first taken by grippers from a feedhoard or other similar source, carried around and printcd. after which the grippers release the head of the sheet which is transferred to the grippers on the traveling carrier. In such machines it is desirable. to deliver the sheet printcd side up. This requires that the chains or sheet carrier travel in a direction opposite'to the direction of travcl of the impression cylinder, so that the direction of travel of the sheet has to be changed as soon as it is taken by the grippers on the chains. iVhcn, however, such as (an'dboard. is being printed, considerable difficulty is cxi'icricured in thus changing the direction of the sheet, and there is, furthermore. liability of. tearing a sheet and injuring the design when the direction of travel is changed in the manner rcfcrrcd to. Further. a carrier having sheet seizing dcyiccs such asgrippers, is practically necessary in these constructions, as the hcad of thc sbcct must be positively takcn. and such carriers arc cumersomc and expensive in construction.
The object of the. present invention is to produce an in'iprovcd printing machine in which the sheets may be delivered fiat and with the. printed side up, in] to accomplish this without changing tlu direction of travel of the ,sheet.
With this and other objects in view, the nvent on consists in certain constructions,

Application filed January 3, 1913. Serial No. 739,993.
and in certain parts, improvements and combinations cally described and pointed Referring to the out. accompanying drawingsr Fignre 1 is a diagrammatic side elevation of so much of a printing machine as is necessary to an understanding of the invention. Fig. 2 is a diagrammatic view similar to Fig. 1, but with certain parts re moved, the position of the cylinders being printing is begun. Fig. 3 is a view similar to Fig. 2 but showing the sheet at about the time the delivery from the impression cylinder to the sheet receiving surface of its cooperating cylinder is effected.
Referring to the drawings which illustrate a concrete embodiment of the invention,
that which they occupy at about the time the 1 indicates a. printing cylinder having aprinting surface 2 and a non-impression sheet receiving surface- 3, serving merely to hold and carry a sheet without functioning in the making of an iinm'ession on said sheet. Suitable sheet holding deviccs, as grippers l, are provided which coiiperate with the sheet receiving surface. in machines embodying the invention in its best form, the printing surface 2 will be a planographic surface, such. for instance, as the rubber blanket ordinarily employed on transfer cylinders. this blanket being. secured on the cylinder in any of the, wellknown ways.
When the invention is embodied in a transfer printing machine. a design carrying cylinder, such as 5, will be provided, this cylinder rccoiving the ink from a battcry of the usual character, generally indicated at 3. In the best. (t)llStllllUtlOllS embodying the invention, this design carrying cylinder will be arrangcdto make two revolutions to cachrevolution of the cylinder 1, thus causing the design to pass the inking rolls twice. so that the ink may be thoroughly worked into the design.
Suitable coop. ating impression means will, of course, be provided. In the particular construction illustrated, this impression means consists of a cylinder. as 7, this cylindcr being arranged to make two revoluas will be hereinafter specifi-.
effects the printing, and on the second revolution, it cooperates with the sheet receiving surface 3 and delivers the sheet thereto. This cylinder 7 will be provided with any suitable sheet taking devices, such, for instance, as grippers 8. Sheets may be delivered to the cylinder 7 in any suitable way. In the particular construction illustrated there is provided a feedboard 9. The usual front stops, indicated. at 10, are provided, these front stops being raised and lowered from a cam on the shaft 11 of the cylinder 7, this cam cooperating with the usual forked actuating rod 1 The feed-board will. ordinarily be raised in order to permit the sheet to pass its guide fingers on the second revolution of the cylinder 7. In order to effect this, the feedboard is hinged or pivoted, as indicated at 12, and is raised or lowered from a rock-shaft 13, this rock shaft being operated from a cam 14 on the shaft 15 of the cylinder 1, the construction being a usual one. I I
The flat delivery mechanism. employed may be of any suitable type. As shown, it
. consists simply of tapes 16 running over the ordinary tape rolls 17. If desired, a stripper of usual form, indicated at 18, may be employed to eflect the clearing of the sheet from the sheet receiving surface 3.
In the construction described, the sheets are fed from the feedboard 9 to the grippers on the cylinder 7, and as this cylinder makes its first revolution, the sheets are printed, the position of the parts being shown in Fig. As the cylinder makes its next revolution, the sheets are delivered from the grippers 8 to the grippers 4 on the cylinder 1. and are laid against the sheet receiving sin-face, the printed side of the sheets being toward the surface. As this cylinder 1 continues its revolution, the grippers 4 are. opened and the sheets deposited printed sidcnp on the tapes 16. It will be seen that by the construction described the sheets are carried directly through the machine and delivered printed side up without any change in their direction of movement.
Changes and variations may be made in the construction by which the claimed invention is carried into effect, and it will be understood that while. the invention is of particular value in transfer 11' chines; it may be embodied, as to some of its features, in machines which do not employ transfer or printing surfaces.
\Vhat is claimed is 1. In a printing machine, the combination with a, cylinder having a printing surface,
and a non-impression sheet receiving surface, of an. impression cylinder making two revolutions to one of the cylinder having the printing surface, said cylinder cooperating with the printing surface on one revolution and delivering the sheet to the non-impression sheet receiving surface on the next revolution, and a flat delivery mechanism cooperating with said sheet receiving surface.
2. In a transfer printing machine, the combination with a cylinder having a pianographic printing surface and a non-impression sheet receiving surface, of a design carrying cylinder for deliverinr the design to the printing surface, a flat delivery cotiperating with the sheet receiving surface to which the sheets are delivered printed side up from the sheet-receiving surface, and c0- operating impression means.
3. In a transfer printing machine, the combination with a cylinder having a planographic printing surface and a non-impression sheet receiving surface. of a design carrying cylinder for delivering the design to the printing surface, a flat delivery cotiperating with the sheet receiving surface, and an impression cylinder making two revolutions to one. revolution of the cylinder having the printing surface. said cylinder cooperating with the printing surface to print the sheet on one revolution and delivering the sheet to the sheet receiving surface on the-next revolution.
-l. In a transfer printing machine, the combination with a cylinder having a planegraphic printing surface and a non'impres sion sheet receiving surface. of a design carrying cylinder for delivering the design to the printing surface, said cylinder being arranged to make two revolutions to each of the cylinder having the design carrying surface, an impression cylinder making two regpolulions to one of the cylinder having the printing surface, and a flat delivery mechanism coiniorating witln the sheet receiving surface.
In testimony whereof. I have hereunto set my hand, in the presence of two subscribing witnesses.
