BERTHOLD HUBER, OF TAUNTON, MASSACHUSETTS, ASSIGNOB TO THE HUBER PRINTING PRESS COMPANY, OF SAME PLACE.

PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 350,056, dated September 28, 1886.

Application filed September 29, 1884. Serial No. 144,220.

To all whom it may concern Be it known that I, BERTHOLD HUBER, a citizen of the United States, residing at Taunton, in the county of Bristol and State of Massachusetts, have invented a new and useful Printing-Machine, of which the following is a specification.

The object of my present invention is the production of a printing-press especially adapted for printing from sheet metal or from stereotype, electrotype, and zincographic plates.

My invention relates to a printing-press in which the impressions are given by the employment of two cylinders, upon one of which is secured the form, the other being fitted with grippers in the usual manner. Y

it also relates to that class of presses in which water and ink are used alternately in the process of printing. In all such former constructions that part of the type-cylinder not used for the form was employed as an inking surface or table, onto which the ink was deposited from the fountain, and from which it was delivered onto the form-rollers. The inking surface or table of presses heretofore employed being type-high, or in the same circumferential line with the type, it was necessary to lift the water-rollers away from the form-cylinder at every revolution of the latter, and therefore it was impossible to drive the waterrollers by gears at the same positive speed as that of the surface-speed of the cylinder.

The object of my invention is to drive the water-rollers as well as the ink'rollers by the same means, and to give both sets of rollers a positive surface-speed.

In this my invention the surface of the formcylinder other than that occupied by the form is disposed below that portion occupied by said form, while the water-rollers,having a surfacespeed equal to that of the form-cylinder, are provided with positive gear mechanism, and are arranged in the circumferential line or printing-line of that portion of the formcylinder occupied by the form, so that in the revolution of the formcylinder the said water-rollers travel over the surface of the form placed on said cylinder, while they do not touch the depressed surface of said for1n-cyl- 5o inder. Furthermore, the ink-rollers are in (No model.)

fixed relation with the form-cylinder, and by reason of the depressed portion, said cylinder comes in contact only with the form placed on the raised or normally high portion of said cylinder. By this arrangement the water and ink rollers in the revolution of the form-cylinder alternately pass over the face of the form or plate placed on the normally high portion of said cylinder, but do not touch any portion of said cylindenas is done in the common form of printing-presses, wherein a portion of the surface of the cylinder serves as an inking-table. Furthermore, the inking apparatus and the cylinder have their driving mechanism connected to and operated by a common shaft, which is in constant engagement with the driving mechanism for the ink apparatus, while it has merely a clutch-connection with the mechanism for the cylinders. The object to be attained by this construction is to permit the inking apparatus to be driven independently of the cylinders, so as to enable an operator to ink up the inkapparatus without inking the form-an operationvery essential to the class of presses to which my invention belongs. Furthermore,the inking apparatus is located above the formcylinder, so as to permit an operator to stand at the back of said cylinder to adjust the zinc plate thereon, or to remove said plate therefrom and substitute another when desired, while the waterrollers are placed beneath the formcylinder.

'lheinvention consists in certain novel combinations and arrangemeuts,as hereinafter particularly set forth and claimed.

Figure l is a vertical section of a machine embodying my invention. Fig. 2 is a vertical cross-section on the line as 00, Fig. 1. Fig. 3 is a plan view of the cylinders and principal gears, the frame-work being omitted. Fig. 4 is a detail to be referred to. Fig. 5 shows details of the clutch mechanism on the drivingshaft, such clutch mechanism being of common construction.

The two side frames, A A and the foundation B constitute the frame-work.

G is the forin'cylinder, onto the high part c of which is fastened the zinc plate, which is bent at a right angle on the forward end and held in place by the nippers a, the tail end Ice ' which meshes into the gear H, loose on a j ourshaft F outside of the frame A proper position on the paper.

being drawn and fastened by a number of clamps, 0 The opposite side, 0", of the cylinder 0 is out below the printing-line, so that in its rotation it will not come in contact with either the form-rollers or water-rollers.

O is the impression-cylinder, and is fitted with grippers c in the usual manner.

In the accompanying drawings the impression and type cylinders are of the same diameter, which, however, is not essential, as their proportions might be two to one.

C is the delivery'cylinder, and is fitted with grippers c. p

D is the fly, and Ethe feed-board.

F is the driving-shaft, journaled in the two.- frames A A.

F represents a tight and loose pulley on the Inside, and nearest the frame A is a pinion, G, fitting loosely on the shaft F, but capable of being fastened firmly to said shaft by the clutch F". By sliding the pinion G toward the frame A it is released from the clutch F, and the shaft F is allowed to revolve without imparting motion to the pinion G. The pinion G engages the pinion G, which is secured to the cylinder 0 by screw-bolts 2,passing through slots 0' in the gear G, to allow the relative position of the gear G and the cylinder 0 to be changed, so as to bring the head-line of the form in its The gear G engages the gear G, which is fastened to the cylinder 0, and this latter gear, G engages and drives the deliverycylindergear G which is fastened to the therefore be seen into the clutch F delivery-cylinder 0 It will if the pinion G is thrown then the rotation of the shaft F will drive the train of gears G, G, and G with their attached cylinders O, OflandG. If the pinion G is thrown out ofthe clutch F, then the rotation of the shaft F will not be transmitted to the said train of gears and their attached cylinders.

Fastened on the driving-shaft F, near itsopposite end, (see Fig. 3,) is another pinion, H,

. nal of the cylinder-shalt, and free to rotate gear H meshes in turn engaging the gear h thereon without moving the cylinder 0. The into the three intermediate gears, H (shown in dotted lines in Fig. 1, and in section in Fig. 4,) said gears H on and driving the dis tributer or vibrator rollers H for the ink, and also the water-distribution roller 0 in like manner. The gear H also drives the inter mediate gear, H which meshes into the gear H, (see Fig. 2,) which is fastened to the ink- "drum I, upon which rest four small rollers,k. The ink is transmitted from the ink-fountain L to the ink-drum I by the roller 75, which oscillates between the said ink-fountain and ink-drum around the shaft Pin usual manner. From the ink-drum I the ink is conducted to and the distributer or vibrator rollers H, as stated before, receive a posiwhich latter,

having a form-surface face below the level of the form-surface, as

tive motionfrom the cylinder'G through two of the intermediate gears, H.

On the outside of the frame A and fastened is a pinion, p, (see. gear p", fastened tori l;-

and the gear 11 0, which oscillates between the fountain-r011. o and the distributer-roll 0 around the shaft 0. The water-distributer roll 0 and the water, form-rollers o are journaled in the arms 0", the upper ends of which are hinged on the studs 0, While their lowerends rest on the co centric-shaft 0 The position of the arms 0", as shown in the drawings,will keep the waterrollers close to the cylinder, and in what might be called the working position, while, upon reversing the eccentric-shaft o the arms" 0 will be lowered to throw the gear H flwhich engages the distributer-roll 0*,out'of gear with the gear H make it convenient to removethe water formrollers from contact with the form-cylinder. By

bringing the cylinder 0 intothe positionwhere' the type-surface 0 will be located between the water-rollers 0 and the first form-roller at the back side of the machine and then sliding the pinion G out of the clutch F on the shaft F the machine is then in the most con venient position for inking up.

Upon putting the machine in motion the cylinders O O O -will remain stationary, but the inking apparatus will be in motion, and the distribution of ink and'water may be adjusted and regulated ready for printing. Did the form-rollers depend upon an inking surface or table on the cylinder 0', then the motion of the cylinder 0 would be necessary during the operation of inking up, and the impression -cylinder 0 would have to be separated from the form-cylinder G. On the other hand, by using instead of an inking surface or table in the form-cylinder aseparateink-drum,

I, I obtain the advantage of running the ink.

and water apparatus independently of the cylinders, and also the advantage of driving the water-rollers in a positive manner, thereby securing a more even damping.
