The invention relates to printing machines for printing addresses by means of printing plates having marginal flanges offset along their long edges opposite to the printing surface. Said machine comprises a base having a recessed track therein for the reception of the printing plates, which are fed below a printing arm with a platen thereon and pivotally secured to the base. Said track has a central raised portion corresponding tothe shape of the printing plates and serving as a guide-way and a support for the printing plates. The usual arrangement of the support is such that only printing plates of the same width may be used. v I

The object of the invention is to create an addressing machine whichisavailable for printing plates of different sizes. An essential feature of the invention is the fact that the support of the printing plates consists of an exchangeable ledge fastened by screws to the previously shaped track. Such construction does not require a troublesome working of the base. Besides it is possible to adapt the machine to the use of other sizes of printing plates solely by exchanging the support.

According to a. further object of the invention the usable means for holding the printing plates down and being arranged along the sides of the removable support are adjustable. Preferably the said U-shaped means, each having one leg extending under the support, are jammed between the table and the support, the table being provided with adjustable or alternately usable abutments. According to a very simple form of execution the fastening screws of the supporting ledge are simultaneously inner abutments for one adjustment of the holding-down means, when a narrow support isused. The holding screws for the guard plates form simultaneously the outer abutments for the other adjustment when a wider support is used.

Corresponding to the adaptability of the table to printing plates of difierent sizes also the platen of the printing arm may be exchangeable.

In the drawing the invention is illustrated in combination with a small printing machine.

Fig. 1 shows a printing machine for printing addresses in a side-view, partly in section according to line I-I of Fig. 2;

Fig. 2 is a plan View of Fig. 1.

Fig. 3 is a part of Fig. l, certain parts being in another position.

A printing arm 2 with a preferably exchangeable platen 3 thereon is pivotally mounted on the base I of the machine. Within the range of the platen the base is provided on its upper face with a recessed track therein for the reception of the printing plates reposing on a removable support. Said support consists of a rectangular exchangeable ledge 4 fastened in position on the recessed track by means of two screws 5. At both longitudinal opposed edges of the. support U- shaped strips 6 of sheet-metal'are jammed for overlapping the marginal flanges on the printing plates to hold them down as to be seen from Fig. 1, in which a printing plate I laid upon the support is indicated by dotted lines. The strips 5 having one leg extending under the support may be adjusted in different positions corresponding to the width of the support 4. If a broad ledge 4 is used as in Fig. 1, screws 9 serve to secure the adjustment of the strips 6, said strips abutting against the circumference of the screws being screwed into the base. These screws 9 are provided with a neck 8 by which the correct distance is secured for two U-shaped guard-plates I9 fastened by the mentioned screws on the base.

' On the base I furthermore the ribbon arrangement is mounted, the ribbon being fed underneath the guard-plates I0. As these parts are not an object of the invention an illustration is not necessary. Fig. 1 shows solely the bar I I pivotally mounted beneath the axis of rotation of the printing arm and serving to control the feeding apparatus of the ribbon.

On the base I a springy abutment I2 and a solid abutment I3 of the printing arm are provided. A draw-spring I8 fastened on the base I engages the printing arm on the pivot I4 and holds the printing arm in the position of rest as shown in Fig. 1 by dot-and-dash lines I5, the springy abutment I2 serving as a damper.

The machine according to the invention may be adapted to printing plates of different sizes by changing the support 4. Fig. 3 shows a support I6 fastened on the base I and having a. smaller width than the support 4. The holding-down strips I1 corresponding to the strip -6 with respect to their shape do not touch the screws -9 here, but the screws 5. In this position the machine is adapted for the use of printing plates of a narrower size.

The invention is not restricted to small printing machines of the described kind. It is also possible to construct tracks of greater machines with automatic plate feeding by means of removable supports screwed on the base. Also when used in combination with such greater machines the advantages of the invention become fully effective, preferably those relating to the manufacture of the machine.

I claim:

1. A printing machine for printing addresses by means of printing plates having marginal flanges ofiset along their long edges opposite to the printing surface, said machine being comprised by a base having a recessed track therein for the reception of the printing plates, a printing arm with a printing cushion thereon pivotally mounted on the base, a removable support mounted in the recessed track for supporting the printing plates, screws holding the removable support in position in the recessed track, opposed ledges of U-shapes mounted along the sides or" the removable support and'each having one leg extending under the latter to be secured in position by the holding screws forthe support, and the other leg overlapping the marginal'flanges'on the printing plates, said opposed ledges being relatively transversely adjustable according to the width of the removable support mounted between same.

"2. A printing machine for-printing addresses by means of printing plates having marginal flanges offset along their long edges opposite to the printing surface, said machine being comprised by a base having a recessed track therein for the reception of the printing plates, a printing arm with a printing cushion thereon pivotally mounted on the base, a removable support mounted in the recessed track for supporting the printing plates, screws holding the removable support in position in the recessed track, opposed ledges of U-shape mounted along the sides of the removable support and each having one leg extending under the latter to abut and be secured in position by the holding screws for the support, and the other leg overlapping the marginal flanges on the printing plates.

3. A printing machine for printing addresses by means of printing plates having marginal flanges ofiset along their long edges opposite to the printing surface, said machine being comprised by a base having a recessed track therein for the reception of the printing plates, guard plates mounted along the edges -of the recessed track and extending partially over the latter,

screws holding the guard plates in place, a

printing arm with a printing cushion thereon pivotally secured to the base, a removable support mounted in the recessed track for supporting the printing plates and intermediate the guard plates, opposed ledges mounted along the sides of the removable support and beneath the guard plates-said opposed ledges having U-shaped edges for overlapping the marginal flanges of the printing plates, said opposed ledges abutting the holding screws for the guard plates and being relatively transversely adjustable by the setting of said holding screws.
