Specification of Letters Patent.

Patentedv Aug. 28, .1917.

To all whom t may concern:

Be it known that I, ALFRED L. PARMELEE, a citizen of the United States of America, residing at Lambertville, Monroe county, Michigan have invented new and useful Printing-Fresses, of which the following is a specification.

This invention relates to presses for the multiplication of impressions or copy.

This invention has utility when incorporated in a roll printing press.

Referring to the drawings:

Figure l is a perspective view of an embodiment of the invention in a rotary printing press;

Fig. 2 is a showing of the inking and impression trains in operative position;

Fig. 3 is also a view of the inking and impression trains but with the inking and impression rolls thrown oif, the throw-off mechanism being shown' Fig. 4 is an end elevation of the roll actuating train; -v

Fig. 5 is a fragmentary view of the inking train features;

Fig. 6 is a fragmentary perspective view of the cutting mechanism; and

Fig. 7 is a fragmentary detail view on an enlarged scale of the feed driving connections.

The printing press embodies the cylindrical rotary ink fountain 1 loosely mounted in the forks 2 by the shaft 3, said roller 1 resting upon the distributing roller 4 coacting with the supplemental ink distributing rolls 5. The rolls 5 have their shafts 6 in the inclined ways 7 allowing these rolls to fall against the side of the roller 4 which has its shaft 8 mounted in the lower part of the forks 2.

Disposed below the roll 4 is the live roll 9 of the inking train mounted on the shaft 10. This roll 9 coacts with the roll 4 and may coact with the rolls 11 on the shafts 12 in conducting the distributed ink from the inking train to the copy 13 on the copy carrying roll 14 mounted on the shaft 15 having eccentric bearings. This copy carrying roll may transfer its copy to the soft blanket or offset 16 on the first offset roll 17 mounted on the shaft 18 which may in turn transfer from its blanket an impression to the blanket 19 on the se'cond roll 2O mounted on the shaft 21 from which continuous copy impressions may be transferred to material This shaft 18 at its opposite end has theV herring-bone gear 32 in mesh with the herring-bone gear 33 on the shaft 15 which, through the herring-bone pinion 34 on the stub shaft 35 drives the herring-bone gear 36 on the shaft 10. This gear 36 has the wrist pin 37 with 'universal joint 38 connected to link 39 having universal joint 40 connected to the bell crank lever arm 41,l

mounted on the fulcrum 42, and its upper arm 43 connected by the universal joint 44 to reciprocate the shaft 3.

Accordingly the operation of the motor 26 rotates the shaft 29 and first offset roll 17. Copy roll 14 is a live or positively driven roll as is also the inking train roll 9. The ink fountain roll 1 is reciprocated across the ALFRED L. PAEMELEE, OF LAMBERTVILLE, MICHIGAN, ASSIGNOR 0F ONE-HALF TO distributing roll 4 and the rotation of the f' roll 9 is transmitted to these follower rolls 5, 4 and 1, as also to the follower rolls 11 for effective distribution of the impression substance to the copy 13 on the copy roll 14. The herring-bone gearing precludes any lost motion in the mechanism notwithstanding the throwing of the parts into throw-off position, and this is also true of the spiral gear drive. The same diameter for copy 13 and roll 9 simplifies the throw adjustment.

ln mesh with 'the herring-bone gear 32 is the herring-bone gear 45 on the shaft 21 of the second odset roll which is in mesh with the herring-bone gear 46 on the shaft 23 of the impression roll, ythereby making a positively driven impression or copy transfer train. The treadle 47 mounted on the fulcrum shaft 48 in the frame 25 is normally held upward by the spring 49 from the frame cross bar 50. When this treadle 47 is .actuated against the resistance of the spring 49 and thrown into the latch 51, this tread lever acts, through'the link 52 and arm 53 to rock the shaft 54 in the frame 25. Connected to this rock shaft 54 is the pair of arms 55 from which extend upward the links 56 connected by arms 57 to the eccentric bearings 2i of the impression roll Further extension links 5S are connected by the arms to the eccentric bearings 6l for the shaft l5 of the copy carrying roll f4. These links 5S have link extensions 62 connected to the angle lever (53 fiXedly fulcrumed intermediate the rolls 1l and connected thereto by the arms (il. The arms of lever 63 have adjustable connections to vary the throw. Thismovement upward of the treadle -l7 rocks this angle lever G3 to throw its central portion out of vertical position and accordingly throw the rollers 1l outwardly in the guides (i5 medially between the shafts l0, 15. This throws this lower pair of rollers of the inking train free of the copy 13, while the upward travel of the links 5G, 58 acting through the arms 57, 60, has so thrown the eccentric bearings 24, Gl, that. the copy 13 is spaced to clear the first offset roll 17 while the impression roll 22 is thrown away from the second offset roll 20.

The herring-bone gearingmaintains the operating registry between the train rollers notwithstanding the throw off' and the movement of the inking rollers of the impression train out of contacting relation. Accordingly, when the treadle is released, the former registry is had at once.

The material to be supplied, as sheets of paper for copy, may be passed from the table 65 and the feeding occur automatically by the driving mechanism from the shaft 2l of the second offset roll which has thereon the mutilated gear G6 to drive the loose pinion 67 on the shaft 68. This pinion (57 has the guide or holding recess (39 fo rest again-st the plate 70 adjacent the mutilated gear 66 in the range of the toothless portion of said gear 66, thereby holding the pinion G7 from rotation except at the toot-hed portion of the gear 6G. This pinion (37 is in mesh with the pinion 7l fast on the shaft 72 carrying the stock feeding cams 73 and the additional cam 74, the latter acting to lift the bar 75 against the resistance of spring 76 and thereby, through the rockshaft 77 hold the fingers 78 in up position to interfere with the feed of paper stock. In the rotation of this shaft 72 when the cams 73 are in stock feeding position the cam 7-l is in position to allow the fingers 78 to be dropped by the spring 7G. The feeding of the paper is normally guided by the guide fingers 7 9.

The travel of the stock from the table (33 as to the cam 73 is facilitated by the pinion 7 driving the shaft 80 acting as a live roll. This shaft 8O is mounted in an oval bearing l and may have its clearance relation as to the cam 73 adjusted by the thumb screw 82, forcing the pinion 79, 7l, into more or less depth of root register.

As the stock passes between the second offset roll 2O and the impression roll 22, it. may be severed into the desired length sheets by the cutting edge or knife 83 anchored by screws Set into the slot in the impression roll 22, scat 85 in theI second offset roll 2.0.

This printing press is of simple compact construction for a wide rango ol' use in turning out superior work even on rough or low grade stock. The offset feature permits the i delicacy of reproduction from copy requiring accuracy and minute showings even on the rougher stocks. tion may occur with the usual copy which at the first impression gives the right or printing impression. This first impression is reversed b v the second ofl'set to give the final printing impression. Regular copy, sayv set up type, as well as cuts may be used as a projecting form copy on this apparatus and s with superior results and a high degree of simplicity for job work.

Vl/hat is claimed and it is desired to secure by Letters Patent is:

A printing press embodying a frame pro- 9 viding a pair of opposing members, a bank of rolls mounted in said members including a first offset roll, driving means for said* offset roll, a copy roll on one side of said offset roll, a second offset roll on the oppo;A S

site side of the first offset roll from the copy roll, an impression roll beyond the second offset roll, gears on said rolls for transmi/ ting driving action from the first offset rgll,` an idler gear by the copy roll gear, an inking roll provided with a gear in mesh with said idler gear, an ink distributing roll provided with longitudinal actuating connection with said idler driven gear whereby said ink distributing roll is reciprocated as to the inking roll, said bank of rolls having their axes lying approximately in a common plane7 said inking roll and copy roll being of similar diameter, and an ink applying follower roll actuated by the inking roll and coacting with the copy roll.

In witness whereof I affix my signature.
