My invention relates to an address printing machine with a blank feeding mechanism. The mechanism comprises a blank holder which is fed step by step in the longitudinal direction of the blank when an address has been twice printed on the blank from a given printing plate and is' the frame of the blank feeding mechanism, is

operatively connected to a one-armed lever, or rocker, which is fulcrumed at one end on the support for the blank holder and whose other end is connected to the blank holder by a short link. The blank holder is guided by a pair of parallel links which are fulcrumed on the support.

In order to combine with the lateral shifting "movement thus imparted to the blank holder, an adjustable longitudinal movement of the holder, in a preferred embodiment of my invention the parallel links are fulcrumed on an anchoring 'plate or slide which is arranged to be shifted at right angles to the feeding movement on the support, and can be held on the support in any desired position.

In the accompanying drawings an address printing machine equipped with the blank feeding mechanism embodying my invention is illustrated'by way of example.

In the drawings Fig. l is an elevation, for the major part in section on the line II in Fig. 2, showing a portion of'the address printing machine and the blank feeding mechanismcwith its blank holder ready for the first impression from a given printing plate.

Fig. 3 is a detail plan view, drawn to a larger scale and showing the blank holder in the same position as in Fig. 2, and the anchoring plate on which the parallel links are fulcrumed, in its central position.

Fig. 4 is a section on the line 'IV-IV in Fig. 3.

Fig. 5 is a plan view corresponding to Fig. 2'

but showing the blank holder ready forthe second impression.

Fig. 6 is-a-plan-view corresponding toFig. 3

'on a shaft 33 below the table.

"is inserted the blank 95. the support 33 engages in teeth at the upper end marked "with "the index' (Cl..2715 l)- "but showing the anchoring plate in its final position atthe right, as viewed in the feeding direction.

Referring now to the drawings, and first to "Figs. 1 and 2, a printing head 2 is pivotally 5 mounted on the table of the machine at 3. The

'mechanism for oscillating the printing head and for feeding printing plates to a printing station has not been illustrated as it is not a party of the present invention.

10 The printing head is equipped with a pin engaging in a slot at the upper end of an arm as An arm 36 extends downwardly from the shaft 355 and the left-hand ends of connecting rods 39 and 4B are pivotally connected to the arm 36.

The right-hand endof the rod 39 is pivotally connected to a cross head which is mounted to slide on a rod 6! and to be fixed thereto by a set screw. The rod ll is the tail end of a feeding sector A l on a shaft &3. The sector 44 meshes with a vertical rack All which is mounted to slide "in the frame it of the feeding mechanism and,

in manner per se known in address printing machines, feeds the blank holder stepwise in the direction of the arrow '35 in Fig. 1 when the sector *M is-turned clockwise, that is, against the arrow i 35.

Mounted to slide on the frame it is a support it for the blank holder. By means which will be described, the support holds and guides a clamp I25 at the rear end of the blank holder in which A pawl, not shown, on

of the rack 47? when the rack moves to the right in the feeding direction (it, carrying the support it in the same direction. In the opposite direction, the pawl is idle.

The mechanism for shifting the blank holder,

' with its clamp I26, laterally, that is, transversely 40 a pinion H2, and those lit" at the right mesh with a pinion H2. The two pinions and the elements connected thereto are exactly alike and so only'the .pinion H2 will be described, the corresponding elements for the pinion H2 being The shaft H3 of the pinion H2 is mounted to rotate in a suitable bearing of the frame 46. A crank H4 is placed on a flange H3 of the shaft H3 with a slot H5 so that the effective length of the crank can be varied. At its free end the crank I I4 is pivotally connected to a slide block H6 in a slot H1 in a rod H8. The rod H8 has rollers H9 at both ends which engage in grooves in the tranverse stays of the frame 46 and it will appear that the rod H8 is shifted to and fro laterally as the pinions H2 and H2 rotate.

A rocker I22 is fulcrumed below the support 48 at I2 3, as best seen in Fig. 4. A U-shaped bracket I21! is placed on the rod H8 and the rocker 22 engages a pin I2I on the rocker. A short link I2! connects the free end of the rocker to a pin E2? on the blank holder. The blank holder, as best seen in Figs. 3 and 6, comprises the clamp I26 already referred to and an angle member I25, I28. The clamp I26 is adjustably mounted on the arm I25 of the angle member by means here shown as a wing nut. A base plate I38 extends to the left from the lower side of the support 43 as far as below the clamp I26 and the angle member is equipped with a block I39, preferably of hard rubber, which slides on the base plate E33 as the blank holder moves. A pair of parallel links I29 and I29 are pivotally connected to the ends of the arm I28 of the angle member with their left-hand ends, and their right-hand ends are fulcrumed on an anchoring plate I3 This plate is mounted to slide in a groove I3I in the support 48 and held in any desired position in the groove by a bolt I32 and a wing nut I33, as best seen in Fig. 4.

A cover I34 is placed on top of the support 48 and secured by screws I40 engaging in threaded holes I35 in the support. An index I36 is placed on the bolt I32 below the wing nut I33 for cooperation with a graduation I31 on the cover I34.

The operation of the blank feeding mechanism will now be described. The parts are supposed to be in the position illustrated in Figs. 1 and 2, in which the first impression is made of a printing plate which has just arrived at the printing station. The slot at the upper end of the arm 34 is so curved that the arm is not influenced when the printing head 2 descends for making the first impression on the blank 95 at the printing station. When the impression has been made and the printing head 2 moves upwards into its initial position, the arm 34 is turned anti-clockwise, as indicated by the arrow in Fig. 1, causing partial rotation of the shaft 33 and a corresponding movement of the arm 36 in the direction of its arrow. This causes both sectors 44 and III] to be turned in the direction of the arrow I45 through the connecting rods 39 and 40. Movement of the feeding sector 44 in this direction is idle, that is, does not feed the mechanism in the direction of the arrow 45, but the shifting sector HE- carries its rack III to the left in the direction of the arrow I46 in Fig. 2. This causes rotation of the pinions H2 and I I2 in clockwise direction, as indicated by the arrows in Fig. 2, and lateral shifting of the rod H8 in the direction of the arrow 5'! in Fig. 2 and into the position illustrated in Fig. 5. The rod, through the means described, moves the rocker I22 in to the position illustrated in Fig. 5, and throws the blank holder into that position in which the blank 95 is ready for the second impression. In other words, the blank is shifted transversely to the feeding direction. By the parallel links I29,

I29 the angle member I25, I28 is shifted in parallel relation to itself. When the blank 95 has arrived in the position illustrated in Fig. 5, and the printing head 2 descends, the second impression of the printing plate at the printing station is made on the blank below the first impression.

When this operation has been performed, a fresh printing plate is moved to the printing station by means known in this art while the printing head 2 ascends. The ascending printing head returns the arm 34 into the position illustrated in Fig. l and this causes rotation of the two sectors 44 and III] against the arrow I45. The feeding mechanism is now fed by the sector 44 in the direction of the arrow 45 and, at the same time, the rod I I8 is returned into the position shown in Fig. 2 from that shown in Fig. 5, and so is the blank holder. Two impressions are now made by the fresh printing plate in the manner described.

In certain cases, for instance, if it is desired that in the second impression of a given printing plate on the blank 95 the second line of the printing plate should be at the side of the first line of its first impression in which case obviously the first line of the printing plate is not printed in the second impression: it is possible by displacing the anchoring plate I3ll in the groove I3I from the central position in Fig. 3, to place the second impression of each printing plate not exactly below the first impression but in staggered relation with respect to the first impression in the longitudinal direction of the blank.

The graduation i3! and the index I36 serve for determining the amount of displacement required for the anchoring plate I30.

Referring now to Fig. 6, it has been assumed that the anchoring plate I39 has been shifted to the right, as viewed in the feeding direction 45, as far as it will go, and secured by the wing nut I33. With this position of the anchoring plate, when the rod H8 is shifted from the position illustrated in Fig. 6 into that illustrated in Fig. 5 in the direction of the arrow 57, Fig. 2, the blank holder moves into the position shown in dot-anddash lines in Fig. 6 and the blank 95 is shifted to the left, against the arrow 45. When the anchoring plate I30 is shifted to the right, the blank holder is moved in the opposite direction, that is, with the arrow 45.
