PRINTING-PRESS.

Specification of Letters Patent.

Application filed January 31-, 1912. Serial No. 674,610.

Patented Dec. 24, 1912.

upon a continuous web of paper, such as is used in the manufacture of paper bags, for example; and an object .of this invention is to provide a printing pressof the type just referred to which will be simple in construetie-n. comparatively cheap in manufacture and most efficient and durable in operation and use.

Another object of this invention is to provide a printing press in which the ink rolls will, during the operation of the press, be kept continuously rotating in order that the ink may be, evenly and thoroughly distributcd.

Inthe drawings illustrating the principle of this invention and the best mode now known to us ofapplying that principle,- Fig ure 1 is a front elevation of our new printing press; Fig. 2- is a side elevation of the e n I same, looking in the d1rect1on of the arrow A of Fig: 1; and Figs. 3 and at are sections on the lines B-B and C-C, respectively of Fig. 1.

The frame of the machine consists essentialiy of two side standards a to each of which is attached a bracket'b. Journaled in the base portions of'the side standards a are the ends of, the driving shaft (1 upon which is mounted fast the driving pulley e adapted to be belt connected to any suitable source of power (not shown). To the top of each. of the side standards a is fastened one end of ahanger f the other end of which is fastened to an end of the ink-container g, which may be of any suitable type. In an opening it in each of the side standards a there is mounted freeto slide a block 2' formed with guide-ribs h, which project into channels formed in the side walls of the openingh. Each of the slide-blocked is formed with a recess in in which is journaled an end of the shaft m which carries the ink-receiving roll n. In each of the slide-blocks 2' immediately below the recess is there is formed a recess is which is similar to the latter and in which is journaled an end of the shaft 0, which carries the inkdistributing roll Between one end of the 0 latter and the ad acent side standard a there is mounted fast upon the shaft 0 a pulley g whlchis connected by the endless belt?" with a pulley s mounted fast upon one end of the drivin V shaft d. The belt 1* passes over apair 0 rolls u of'a belt tightener t. The rolls u are mounted in a fork-like frame -v having a stem or a plunger 7) which is slidably mounted in a bracket 'w and is formed with a collar '12 between which and the opposed side of the bracket to there is interposed a coil spring a; which tends to force the plunger o outwardly from the bracket against the tension of the belt 0".

Upon each end of the shaft d there is mounted an eccentric 3 upon which rests a roller 2 which is carried by the lower end of a slide-block 2, which is mounted in an opening 71, in. the bottom of one of the standards aand is connected with the slide 30 block 2' directly above it by means of a twopart pitman or connectingrod 3. By means of a turn-buckle 3 the inner opposed ends of the two parts 3, 3 of the two part pitman 3 are joined. By turning the turnbuckle, the slide-blocks z, 2 may be adjusted toward and from each other to allow for different sizes of the plate-roll hereinafter to be described.

J ournaled in the side standards a are the ley 9 mounted upon the end of the driving shaft d opposite that on which is mounted the pulley s. The gear 7 meshes with a gear 10 mounted fast upon a shaft 11, which is arranged directly above the shaft 4 and the ends of which pass through openings h" in the side standards a. Upon the shaft 11 is mounted the plate-roll 12 which carries the type-block or type-plate (not shown).

.Each side standard a is provided with brackets 13 formed with threaded openings through which passes a vertically-disposed rod 14 having its upper portion threaded and its upper end provided with a hand wheel 15 and its lower end with a fork 16 which straddles one end of the shaft 11 which carries the plate-roll 12. By turning the hand wheels 15 the pressure upon the p1ate-rol1" shaft may be varied and the pressure of the plate-roll 12 on the bed-roll 5 changed.

The roll X of paper is supported on a spindle 0 and from. it is led a web Y which passes between the plate-roll 12 and the bedroll 5. One end of the spindle c is journaled and is free to slide lengthwise in the journal-box 0 carried by one of the brackets Z), while its other end is formed with a collar 0 having a groove 0* in which is mounted a fork 17 from which projects through a slot in the bracket Z) a stem 18 formed at its lower end with a threaded opening. Through the latter passes the threaded portion of a screw shaft 19 which is carried by the bracket b and one end of which is provided with a hand wheel 20. By turning the latter the spindle 0 may be shifted back and forth to adjust the position of the roll X.

As the shalft (Z rotates, the ink-rolls n, p, more up and down, as will be readily understood from the foregoing description taken in connection with the accompanying drawings. The ink-receiving roll a at the end of the upward movement of the slideblocks 2' touches the bottom of the ink-container g and thus receives a charge of ink, which is tran ferred to its coacting roll 2). This inkalistrihuting roll 7) at the end of the downward movement of the slide-blocks touches the tzype-hhick or type-plate (not shown) on the plate-roll 12, for the purpose of inking the same. Since the ink-rolls n, p are kept continuously rotating, the ink will he evenlv and thoroughly distributed.

\Ve claim:

1. A. printing-press comprising a plateroll; a bed-roll; a driving-shaft which is connected with and drives one of said rolls; a pair of ink-rolls; an ink-container; reciprocating mechanism which is driven by said driving-sl'iatt and which moves one of said ink-rolls into and out of contact with said ink-container and the other of Said ink-rolls into and out of contact with one of the first-named rolls; and mechanism which is actuated by said driving-shafti and which drives said ink-rolls continuously while the san'le are maintained in active opcrative relation to the first-named rolls by said reciprocating mechanism, in the normal printing operation of the press.

2. A printing-press comprising a plateroll; a bed-roll; a driving-shaft which drives said rolls; a pair of ink-rolls; an ink-com tainer; reciprocating mechanism which moves one of said ink-rolls into and outof contact with said ink-container and the other of said ink-rolls into and out of Contact with said plate-roll; and mechanism which keeps said ink-rolls continuously rotating, while said reciprocating mechanism moves one of the same into and out otfeonhacl; with said ink-container and the othertlier'eotintohnd out of contact with said plate-roll, in the normal printing operation of the press.

3. A printing press comprising a plateroll; a bed-roll; an ink-container; a pair of ink-rolls; reciprocating mechanism which reciprocates the latter between said plateroll and ink-container; a driving mechanism; a belt which connects one of said inkrolls with said driving mechanism and which maintains said ink-rolls rotating continuously during the operation of said reciprocating mechanism; and a belt-tigl'itener over which said belt passes.
