MANIFOLD-WEB-I'RINTING MACHINE.

Application filed Julie 29, 1926. Serial No. 119,279.

This invention relates to the construction of manifold-web-printing machines both inconnection with a typewriting machine and independently thereof.

In my co-pending application, Serial No. 631,956, filed April 14, -1923', (now Patent No. 1,592,470, dated July 13, 1926), there is disclosed a manifold-web-stamping machine in which carbon-sheets are held interleaved between superposed plies of a longitudinallyfan-folded work-web, by means of blades which project transversely to the web between the plies thereof alternately from opposite sides, the blades being positioned to the rear of the stamping bed.

In the present invention, long rolls of carbon are employed instead of relatively short sheets, and means are provided for feedin carbons from rolls at either side of the we and for conducting the carbons between the superposed plies over the stamping or printing bed, and then winding them upon a take-up roll. By employlng long rolls of carbons, fresh sections of which can be fed to printing position as the advance sections become worn, it is not necessary to replace the carbon-manifolding elements as often as when relatively short sheets are used.

A feature of the invention resides in the provision of pairs of diagonal guides, which are arranged for conducting a carbon in between superposed plies of a longitudinally fan-folded work-web from a feed roll lo cated at one side of the web, thence along the work-Web over the printing bed, and out again to be wound up on a take-up roll. As the plies are joined along one side, the guides are positioned on both sides'of the web whenever the latter includes more than two plies. Another feature resides in positioning a pair of such diagonal guldes with the feed-roll aide in front of the guide oposite the ta e-up roll, and arranging the atter with means to prevent it from unwinding. The drag of the interleaved work-plies as they are moved forward according to this arran ement tends to keep the carbon smooth an taut without danger of unwinding it from the feed-roll or takeup roll.

Other features and advantages will hereinafter appear.

In the acc mpanyin drawings,

Figure 1 is a partial longitudinal seccarbon-take-up roll which may be employed in the present invention. I

Figure 4 is a diagrammatic view illustrating how a plurality of carbons maybe interleaved between the work-plies of a lon itudinally-fan-folded work-web from t e sides of the latter.

Figure 5 is a fragmentary plan view of the printing machine shown in Figure 1.

Figure 6 is a fragmentary plan view of the printing machine of the invention arranged with feed-rolls, take-up rolls, and diagonal guides for interleaving carbons between the superposed plies of a longitudinally-fan-folded work-web.

The web-printing machine includes a main frame 10, a printing bed 11, and a platen 12 fastened to an arm 13 which is pivoted about a shaft 14 and which has a lower forwardly-extending lug 15 connected to a plate-feeding mechanism generally designated as 16, which mechanism is arranged to move plates 17 from a magazine 18 over the main frame 10 to the printing bed 11.

A work-web W may be guided from the rear of the machine over the magazine 18 and along the top of the main frame 10 by rollers 19, 20 and 21. The work-Web W may be advanced forwardly over the printing bed by means of rolls 22 and 23, mounted at the front of the frame 10 and arranged to be rotated upon upward movement of the platen 12 by engagement with a gear-segment 24, which may be operatively connected to the arm 13 by a bar 25. The construction and operation of the abovementioned parts of the machine may be substantially the same as for like parts described in my above-mentioned application.

For manifolding a work-web whose superposed work-plies are not joined at the'sides, carbon-feed rolls 30 and a take-up roll 31 may be mounted on opposite sides .of the work-web, as shown in Figures 2 and-5,. To print with ink on the original or lowermost member of a set of superposed forms, an inked ribbon 32 may be passed across the printing bed under the lowest ply of the superposed work-plies. Carbon from the lowermost feed-roll 30 may be passed between the lowest and second lowest workplies, and across the frame to be fastened in any suitable way to the take-up roll 31. Carbon from the second lowest feed-roll may be passed between the second and third lowest work-plies, and operatively fastened to the take-up roll 31, In like manner, the carbon from the remaining feed-rolls may be passed between the proper web-plies and fastened to the take-up roll 31, which may have a handle 33 for winding the carbon across the printing bed 11 to bring fresh sections of carbon to position for manifolding the superposed forms. The take-up roll may have atoothed wheel 34, and a springpressed dog 35 engaging the toothed wheel to prevent backward rotation of the take-up roll. Each carbon after passing from its feed-roll 30 may be led over a roll 36 adjacent the top feed-roll. A second roll 37 Cmounted in the end of a spring-pressed bracket 38 may be arranged to press the carbons down against the roll 36' which will tend to cause the carbons to be'unrolled evenly under a suitable tension. To provide additional means for holding the carbons satisfactorily taut between the work-plies, spring-actuated friction brakes 39 may be arranged in a well-known way around stubshafts 393 so as to engage the feed-rolls 30 and retard the rotation of the latter. The carbon of'the feed-rolls may be wound on hollow spindles 30, intocwhich the stubshafts 39 may be fitted. The stub-shafts may be retracted and the feed-rolls easily removed when desired.

To manifold superposed forms of a longitudinally-fan-folded work-web whose plies are connected at the sides, it is impossible to have the carbommanifolding elements pass through the work-web from a feed-roll to a take-up roll in the manner just described above. In order to pass the carbon between superposed work-plies of a longitudinally-fan-folded work-web at the printing bed, and then conduct the carbon to the take-up roll, provision is made in the present invention of feed-rolls 40 mounted on each side of the work-web W in front of the printing bed 11. Carbon from the feed-rolls 40 may pass preferably at right angles to the work-web and between two desired workplies, and be turned around a diagonal guide 41 of a guide-plate 42 in the opposite directionto the forward movement of the workweb. After extending past the printing bed 11, a carbon may be turned around a second diagonal guide 43 of the plate 42 and be conducted to a take-up roll 45, mounted on the same side of the work-web W as the feed-roll 40 from which the carbon started, and int-he rear of the feed-roll. The feedrolls 40 may be arranged with friction brakes 46, likethose employed on feed-rolls 30. The take-up rolls 45 may have handles 47, toothed wheels 48 and dogs 49 arranged to function like the similar parts of the takeup roll 31.

In Figure 3 is illustrated an advantageous form of a carbon-take-up roll for use with longitudinally-fan-folded work-webs. The spool 45, on which the carbon may be wound, is positioned above a guide-roll 51 whose lower edge is approximately level with the top of the printing bed 11. By this construction the carbons may be directed along a substantially level plane to the proper guide-plate 42, by which to rotate the spool and a handle 47 may be positioned high enough so as to be clear of the main frame 10 or adjacent feed-rolls 40.

By making the diagonal carbon-guides 41 and 43 from a single plate 42 and leaving an opening 42 therein over the printing bed 11, an advantageous construction is secured, which gives a very desirable rigidity as Well as economy.

By positioning the feed-roll guide 41 in front of the printing bed 11 and the take-up guide 43 in the rearof the printing bed and arranging to wind new sections of thecarbons into position from frontto rear, that is, in the opposite direction to the movement of the work-web W, and V by arranging the toothed wheels 48 and dogs 49 to prevent the backward rotation of the take-up-rolls 45, the friction of the forwardly-moving workplies on the carbons may be utilized to keep the interleaved carbons smooth and taut without danger of unrollin them from the feed-rolls or the take np roils.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be'uscd without others.
