NEW YORK, N. Y:, A confort-Arroyo' Nnwgvonx WEB-PRINTING j I Application mea Nbvember 27 ,1192s`-7f serigilNol' '322,19aj v This invention pertains to improvements in web' printing. machines of the class kused for printing newspapers vand similarcproducts. In my copending application Serial No. 267,330, filedAprilll, 1928,1 disclose a multi-unitprintingmachine. in which 'the' press units are arranged with their two printing couples in superposed yrelation one to the other, in narrow framing thereby providing a press unit ofunus'ually small Vdimensions longitudinally of the machine, yet still retaining most of the desirable features of the machines then in use, s

The invention hereinA disclosed constitutes a further improvement, with'the object of providing a press unit in which one ofthe printing couplesis superposed over the other couple in narrow framing and in which all of the printing cylinders are accessible from one floor level.

Another object is to provide awpress unit yhaving a driving mechanism of improved design. e Y Y It is also an object of the invention `t0 provide a press unit of'generally improved construction, whereby the device will be simple, durable and inexpensive in Vconstruction as well as convenient, practical, serviceable and eflicient in its use. j

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination .and arrangement of parts, and in the details of construction hereinafter described and claimed, it being understood that various changesinthe precise embodiment of the invention hereindisclosed may be made within the scope of what is claimed without departing from the spirit of the invention.V

The drawing which forms a part ofv this specification shows a side view in outline of a portion of a multi-unit web printing machine. Two press units and a folder are shown for the purpose of illustrating the invention.
