SPECIFICATION forming part of LettersvPatent No. 558,996, dated April 28, 1896. Application filed May 22, 1894:. Serial No. 512,140. (No model.)

To @ZZ whom, t may concern:

Be it known that I, LOUIS VfSOUTHGATE, a citizen of the United States, residing at Worcester, in the county of lVorcester and State of Massachusetts, have invented a new and useful Improvement in Printing-Machines, of which the following is a specification.

My invention relates particularly to what are known as traveling-cylinder Vprintingpresses; and the object of my invention is to provide a machine for printing and perfecting a web of paper by means of impressioncylinders which are reciprocated in a curved path of travel; and to this end my invention consists of the parts and combinations of )arts as hereinafter described and more ar-` ticularly pointed out in the claims at the end of this specification.

In the accompanying two sheets of drawings, Figure 1 is a diagrammatic sectional view of a printing-machine constructed according to my invention, and Fig. 2 is 1 a similar view showing the parts in a different relative position.

Referring to the drawings and in detail, A designates an impression-cylinder, which eooperates with a form-bed O and is journaled upon a shaft mounted in a pivoted yoke or framework formed by arms 29, which are journaled upon a horizontal shaft 30. Mounted upon and carried by the journals of the impression-cylinder A, I provide suitable carriages or frames, in which are mounted form-rollers F F and F F', which cooperate with ink-fountains G G and the ink-tables carried by the form-bed to properly ink the form of type which may be secured upon the bed.

In order that the form-bed O may tip or oscillate to conform to the path of travel of its impression cylinder, the form-bed is journaled on a central transverse horizontal shaft 5l.

B designates the second impression-cylinder, which is j ournaled upon a shaft mounted in a pivoted frame or yoke formed by the arms 32, which are journaled on a horizontal shaft Mounted upon and carried by the journals of the impression-cylinder B, I provide carriages or frames, which are also provided with form-rollers F F and F F', which cooperate with l ink-fountains G G and ink-tables carried by the form-bed D to properly ink the form of type secured upon the form-bed.

In order that the form-bed D may be tipped or oscillated to conform to the path of its impression cylinder, it is journaled upon a transverse horizontal shaft 56.

Vith the impression-cylinders and forinbeds thus arranged a web of paper maybe led from the web-roll W, j ournaled at one end of the press, up between the feeding-in rollers l0, ll, and l2, under a looping-in roller 13, over a guide-roller 14, around a guideroller l5, down, under, and around the first impression-cylinder A, over a guide-roller 1G, over and around the guide-rollers 17 and 1S, around the roller 19, down, under, and around the second impression-cylinder B, over the guide-roller 20, around the roller 2l, under and around the looping-out roller 22, up between thefeeding-out rollers 23, 24, and 25, from which feeding-out rollers the web may be led over the guide-roller 26, down and out or folding device.

The gearing which I preferably employ for actuating my improved printing-machine may be arranged as follows:

35 designates the power-gears, which are fastened. upon a shaft, to which power may be applied in any approved manner. Meshing with and engaging the gears 35. I pro- `vide intermediate gears 34, which in turn mesh with and engage driving-gears 2G,which are fastened upon a shaft 260. -Fastened upon the shaft 260 are cranks 27 which are conof pitmen 28, the arms 29 being in turn connected to the arms 32 by means of pitmen 3l.

The lo oping-rollers for intermittently drawing the web through the press may be operated in any approved manner, and, as shown in the drawings, the power-gears 35 mesh with and drive gears 36, secured to a shaft 37, which carries suitable cams 33 for moving the looping-rollers in one direction.

' As shown in the drawings, T-shaped levers nected with and oscillate the arms 29 by means of the press to any approved form of cutting Ioo pivoted on a horizontal shaft are provided With horizontal arms 42, connected at their outer ends to frames 420, in Which is journaled the looping-in roller 13. The downwardly-extending arms 39 of the T-shaped levers are connected by pitrnen 44 With bellcrank levers 45, j ournaled upon a horizontal shaft 46, and actuating-arms 47, which carry the looping-out roller 22, these parts being actuated in one direction by means of the cams 3S and being moved in an opposite diy rection by means of springs 43, secured to the pitmen 44.

Meshing With and engaging the gears 3G I provide gears 48, secured upon a horizontal shaft 49, located directly below the shaft 5l, upon which the form-bed C is journaled. For the purpose of oscillating or tipping the form-bed C to conform to the path of travel of its impression-cylinder the shaft 49 is provided with cams 50, Which engage With rollers journaled upon lugs 52 and 53, extending down from the form-bed C, the cams 50 being so proportioned that the form-bed Will be tipped or turned and the type-forms held in contact with the impression-cylinder While the impression-cylinder is oscillated or reciprocated over its bed.

The form-bed D is connected to the formbed C by means of the extended arm or lug 52, extending down from the form-bed C, the rods or links 54 and the arms or lugs 55 extending down from the form-bed D, and the type-bedD will thus be oscillated or reciprocated synchronously with the type-bed C to retain its type-forms in contact with its impression-cylinder as the same is oscillated or reciprocated thereover.

The feeding-in rollers, the feeding-out rollers, and the distributing-rollers of the inl:- fountains may be actuated by any of the usual forms of gearing which are used in presses of this character, and I am aware that many changes may be made in the construction of my printing-machines by those who are skilled in the art without departing from the scope of my invention, and that many different means may be used for tilting or oscillating the form-beds to conform to the-path of their respective impression-cylinders, and I do not Wish, therefore7 to be limited to the construction which I have shown and described, but- What I do claim, and desire to secure by Letters Patent of the United States, is-

l. The combination in a Web-printing machine, of a pivoted frame, an impressioncylinder mounted therein, Web-guides also mounted in said frame, means for oscillating said frame, a form-bed, means for moving the same to conform to the path of travel of the impression-cylinder, Web-guides for leading a Web to and from the cylinder, guides mounted in said frame, and a Web-shifting device arranged to shift the Web when the impressioncylinder is out of impression, substantially as described.

2. The combination in a Web-perfecting printing-machine of pivoted frames, an impression-cylinder and Web-guides also mounted in said frames, means for oscillating said frames, a form-bed with which each impression-cylinder is adapted to coact, means for moving the form-beds to conform to the path of travel of the impression-cylinders, Webguides for leading a web to one of said cylinders, from this cylinder to the other cylinder, and from the last cylinder, and a Web-shifting device arranged to shift the web when the impressioil-cylinders are off impression, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
