'WILHELM 2113121., 01? BERLIN, GERMANY- OYLINDER PRINTING MACHINE WITH RECIPROCATING CARRIER.

Application filed March 10, 1925, Serial No. 14,547, and in Germany September 5, 1923.

This invention relates to cylinder print ing machines with reciprocating carriers and its object is to provide means whereby sheets and the like may be printed and successively numbered in a single pass through the machine.

In continuously running rotary printing machines sheet numbering devices have been used in which the successive number types were brought into operative position by a cycloidal or like cam member. The application of such numbering devices to cylinder printing presses with reciprocatifng carriers has not hitherto been success- According to this invention a rotary numbering member operates against the printing cylinder of a cylindrical printin machine with a reciprocatin carrier an this rotatable numbering mem er carries one or more numbering devices. Y

By this means the operations of printing and numbering the sheet are performed in a single working operation or. pass, whereas it has hitherto been necessary to pass the sheets first through one cylindrical press to print the sheet and then through a second press to effect the successive numbermg. types are mounted in a very complicated frame which efiects the resetting of the numbering mechanisms by the action of a fixed stop. Thus in addition to the elimination of a second printing operation, I am able to dispense with this complicated and expensive numeral frame. To these material advantages must be added the saving in time caused by the printing and numbering being efiectedsimultaneously as the drying also proceeds simultaneously.

In some cases I eifect the progressive changing of the numbering type by the combined action of a cam member mounted on the printing cylinder and. operable by mechanism such as a roller and oscillatable lever so that the cam on the printing cylinder operates on the numbering device or devices at one revolution and is switched into a position, at the next revolution of the printing cylinder, in which the cam does not advance the number type.

According to the invention a plurality of numbering devices are arranged on rings, which are shiftably located in spaced relation on a special shaft and the types of each numbering device are shifted by means printin In this known form the number of.

of swinging interconnected levers, each of which is equipped with a cycloidal cam' member by means of which the numbering device is reset.

The invention will be better understood from the following description of the forms illustrated by way of example in the accompanying drawings, in which,

Figure 1, 1s a diagrammatic side view of a printing press with an automatic numbermg dev1ce organized in accordance with this invention and in which the cylinder is stopped after a single revolution.

Fig. 1 shows a detailed view in plan of a plurality of the cams on the common shaft 9 and the relation 0 the lever 7a.

Figure 2, shows the invention applied to a two revolution machine. 7

Fig. 3 shows the lever mechanism according to the invention and the cycloid cammechanlsm connected to the same.

Figure 4, shows, also in diagrammatic form, a modification in which the progress ve movement of the numbering mechanisms, carrled on separate rotating members, is effected by a cam member on the cylinder and is adapted to be switche by a cam rod and oscillating lever.

Figure 5, and 6 are diagrammatic views showing the ordinary type of numbering mechanisms mounted on a rotating numbering member or carrier instead of a numbering frame.

In carrying the invention into effect according to the form shown in Fig. 1, the cylinder at is stopped after eachcomplete revolution. This cylinder is provided with y a driving gear I) which engages with a car 0, which also drives the ring (1 on w ich the numbering devices are mounted. The pitch circle of the gear 0 is an aliquot fraction of-the pitch circle of the toothed ring I) of the printing cylinder. illustrated will be employed when numbering smaller sized sheets or cards. When the cylinder a rotates, the ring (1 also rotates and when the cylinder a is stationary, so also is the ring d.

The progressive advancement of the numbering type is efiected by a cycloidal cam into or out of operative position The device here member f which may be switched into or out of operative position by operating the lever 71 to swin the cam member about the axis 9. The .num ring type boxes 6 are mounted on the ring d and the roller of the oscillation arm of the numbering mechanism a runs up the slope of the cam f and so moves the number type one step onward. At each revolution of the ring (2!, the numbers presented by the numbering devices are changed.

In the two revolution cyhnder machine shown in Figure 2, the ring 71' is also an aliquot fraction of the printing cylinder 70. In this case two rings i and l are necessary as the cylinder of two revolution machines is generally smaller in diameter than in the case of the machine illustrated .in Figure 1. The paper lies over practically the entire periphery of the cylinder in this form while in the form of machine according to Figure 1, only about half of the periphery is encircled by the paper. The numbering carrier member is thus of necessity given a much smaller diameter ln-this second form. In consequence it 1s found necessary to support the numbering mechanisms on two carriers arranged one over the other so as to cover the entire paper. It will be understood that one numbering carr er prints on the first half of the paper, while the other prints the second half. The carrier bodies 71* and Z are thus each of half the peripheral length of the printing cylinder. In this way the entire sheet, is numbered at the first complete revolution of the printing cylinder, whereupon the cylinder is is raised, as indicated by the double headed arrow in Fig, 2, and in this raised position it completes its second revolution while the carriage returns without effecting any printing operation. In this raised osition the gears remain in engagement ut the number types do not contact with the paper sheet.

According to the form shown in Fig. 4, the periphery of the printing cylinder at is generally double that of the pitch circle of the gear a which is mounted on the shaft 0 which drives the annular carrier 03. In this case the gear 0 rotates through two revolutions foreach revolution of the print ing cylinder. The paper, in operation, in this case only lies around about one half of the periphery of the printing cylinder so that the pitch circle of the gear 0 is substantially equal to the printing surface. Generally a fairly thick sheet is laid around the printin cylinder on the printing surface thereof an corresponding in size to the setup face of the type. The rotatable annular carrier 03 is mounted on the axis 0 and the numbering mechanisms 6 are fixed to this carrier in the known manner. It is necessary to operate these mechanisms to advance the number types by means of the cam member 7 but this must only occur at alternate revolutions of the gear wheel a, while at the intermediate revolutions the number changing gear must be inoperative,

slot 8 The lever z is keyed to the shaft gwA roller Z contacting with a segmental cam m on the printing cylinder operates a spring pressed cam rod is coupled to the lever 71. The cam piece 7, which operates the numbering mechanisms, swings with the arm a which is keyed to the axis 9. Thus when the cam segment m co-operates with the roller Z to swing the arm 71, the cam piece f is out of operative position and the rotation of the carrier 03 can proceed without causing any fresh setting of the number type in the numbering mechanisms e. a

It will be understood that in the form shown in Fig. 1, the first half of the paper sheet is printed with one number and the second half with the next following number. In the form shown in Fig. 4, however, the advancement or re-setting of the numbering type is intermitted and an inoperative or idle revolution follows the-number printing revolution. Fig. 1 thus illustrates the method of re-settin mechanism describe with reference to Fig. 4: illustrates how the re-setting is made intermittent in such a way as only to take place once at each revolution of the ing cylinder. In this way sheets 0 any desired size, within the limits of practice, may be successively numbered, whereas the device according to Fig. 1 applies only to smaller sized sheets or cards.

In Figures 5 and 6, the t pe of numbering mechanism, hitherto only employed in numbering frames, is shown asv mounted in a rotatab e carrier with suitable operating mechanism for effecting the progressive resetting of the numeral types.

According to the form shown in Fig. 5; the numbering mechanism e of the known type is mounted on a ring 03. The mechanism is provided wsoh a roller 9 adapted to move backwards and forwards in a guide in the path indicated by the double headed arrows. This reciprocating movement resets the number type. In machines using numbering frames, this resettin or o eration of the roller g was e ected y links mounted on a special frame. According to this form of the present invention, the roller 9 is operated by contacting in its revolution with a fixed spring f, which holds up the movement of the roller sufficiently long to effect the resetting of the numeral type. The roller g on completion of the resetting operation is at one extremity of its stroke and it then forces the spring 7 to the right in the direction of the arrow and the reset numbering device moves on with the rotation of the carrier body d. The spring f now freed from contact with the rollers reverts to its normal Iposition. The sprin f is fixed to a ring 9 xed to shaft g an rotatable by means of a lever 2'.

rint- Ell the numbers while the a In the form shown in Fig. 6, the known star wheel r rotatable about the axis 7' The star wheel r is subjected to the action of a brake such as a band It around a brake disc on the axis 7'. The brake band t is attached to one end of a lever a mounted to swing about the pivot 11. and subjected to the action of a weight 0. The friction on the brake is sufiicient to cause the roller g to be moved to re-set the numeral printing type and when the roller reaches the end of its operative stroke the star wheel 1' is moved forward into a position to co-operate with. the next on-coming roller g. Other types of numbering mechanism may be applied such as the star type of numbering mechanism. It will be understood that one or more such carrier bodies may be adapted to work up against the printing cylinder and each of these bodies may carry one or more numberin mechanisms.
