WALTER SCOTT, OF PLAINFIELD, NEIV JERSEY.

PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 480,970, dated August 16, 1892. Application filed February 10, 1891. Serial No. 380.891. (No model.)

T0 at whom it may concern.-

Be it known that I, WALTER Soorr, a citizen of the United States, and a resident of Plainfield, in the county of Union and State of New J ersey,have invented certain new and useful Improvements in Printing-Machines, of which the following is a specification.

My invention relates to printing-machines wherein the impression is taken between a flat bed carrying the type-form and a cylinder.

The object of my invention is to increase the capacity of such machines in printing and delivering sheets, whether printed upon one side or perfected.

I employ to print and deliver sheets printed upon one side onlyareciprocating type-bed, an oscillating impression-cylinder, and duplicate feeding and delivery devices. To print perfecied copies, I employ two type-beds, two impression-cylinders, and, preferably, duplicate feed and delivery devices for each cylinder and duplicate sheet-carriers between the first delivery and second feed devices. It is obvious that in the last case there may be but one feed and one delivery apparatus for each cylinder, with one sheet-carrier between the two cylinders, without in any way departing rom my invention.

My invention is shown in the accompanying drawings, forming part of this specification, in Which- Figure 1 is a side elevation of the machine, showing the essential parts. Fig.2 is aview, partly in section, on the lineAB, of a portion of the machine.

In the machine shown in the drawings I em ploy two type-beds T T and two oscillating impression-cylinders C 0 The bed T and cylinder 0' are geared together by the rack D and gear-wheel E, while bed T and cylinder 0 are connected by the rack F and gear- Wheel G. The rack F may be double and drive the cylinder 0' by means of the intermediate gear II and gear E, dispensing with rack D, or all the gearing shown maybe used to drive the cylinders. There are slots, as X Y, in the framework of the machine (the frame is not shown) to clear the frame K, connecting the type-beds. Areciprooating motion is given the beds by the crank M, connectingrod L, and pin N on the frame K. The crank M may be driven in any suitable way-for instance, it may be on the shaft of the gear V or on the side of gear V and the gear be driven by a pinion, pulley, and belt from any suitable source of power.

Tapes l2 and guides 13 are used to feed the sheets to the first cylinder 0. Tapes 16 and guides 17 are used to carry the sheets from the first cylinder 0 to the second cylinder 0 and,in conjunction with guides 17, to feed the sheets printed upon one side to the second cylinder 0 I show delivery-cylinders O P to take the sheets from the cylinder 0 and to feed the same to the carrying-tapes 16. The delivery-cylinders Q R take the sheets from the cylinder 0 and deliver the same in any suitable Way, as to fliers or to tapes, as 20, which may run the sheets to fliers or to a folding mechanism. The

tapes

12, 16, and 20 run around suitable pulleys, as 21, as ordinarily. One part of each pair of

tapes

16 and 20 runs around its corresponding delivery-cylinder, as shown.

Grippers l4; and 18 on the cylinders 0 C respectively, take leading edges of the sheets from the feed devices, while grippers 15 19 on the delivery-cylinders O P and Q R, respectively, take the sheets from the impressioncylinders, the grippers of which open at the proper times. These grippers are operated at the proper times by any suitable means commonly used for that purpose.

The delivery-cylinders are given each its own rotary motion in the directions shown by the arrows by any suitable means, such as those set forth in my patent numbered 456,741 and dated July 28, 1891, or other means may be used, it being understood that the means for driving these cylinders form no part of the present invention.

The tapes are operated in any suitable way by means usually employed for that purpose.

The forms 10 and 11 are inked by the rollers I I, disposed as shown. There may be inktables on the lower bed and the usual fountains, duct, and distributing-rollers. For the inkingrollers of the upper bed fountains, duct, and distributingrollers may be employed instead of the ink-tables, fountains, &c., as this gives a more compact arrangement of the sheet-carriers 16 without interference from the upper type-bed.

The sheets may be out from rolls and fed to the tapes 12, or they may be fed in by hand, though I prefer the first method.

I have shown the machine as delivering the printed sheets to a folder for convenience. show seven sheets a, b, 0, cl, 6, f, and g in the various stages of feeding, delivering, carrying, and delivery to a folder. I have also shown an outside form on one of the type-beds as the lower one and an inside form on the other as the upper one. This arrangement permits the sheets to be properly folded by the folder. In the positions shown the beds will move to the right, turning the impressioncylinders in a corresponding way. After a short movement of the parts the grippers 14: and 18 at the left-hand sides of the cylinders C C will grasp the leading edges of the sheets a and b. The sheets e f will be run 06 the delivery-cylinders O Q. The sheets 0 (1 will be run along toward the feed-guides, andthe sheet g will be run into the folder. As the parts continue to move, the sheets a b will take impressions on their under sides and will be delivered to the grippers 15 19 of the cylinders P B, respectively, and from these cylinders to the tapes 16 20 on that side. lVhen the typebeds have reached their extreme right-hand positions, the sheet 0 will be in a position corresponding to that shown for the sheet a; sheet 61 will be in one similar to that shown for the sheet 1); sheet 6 will occupy one corresponding to that shown for sheet d; sheet f will be running into the folder, and sheet g willbe folded. On the return stroke of the beds the grippers 14. 18 (shown to the right in the drawings) will take the leading edges of the sheets 0 cl, and as the stroke is completed the parts will be in the positions shown, it being understood that new sheets will be in the places occupied by sheets a c, that sheet a will be where d is shown, 61 wherefis shown,

f will be folded, a will be where e is shown, e

will be where b is shown, I) where g is shown.

In case it were desired to print upon but one side of a sheet, the tapes 16 or the cylinders O P can be arranged to run the sheets upon fliers and so to delivery-boards.

Having fully described my invention, what I desire to secure by Letters Patent is- 1. In a printing-machine, the combination of two reciprocating type-beds, two oscillating impression-cylinders, a sheet-feeding appliance for each cylinder, a sheet-delivery device for the cylinder taking the first impression, and a sheet-carrier between the delivery of the first and the feed of the second i111- pression-cylinder, substantially asdescribed.
