{TED STATES TEN orrica CARL WINKLEE, OF BERN, SWITZERLAND, ASSIGNOR TO MASGHINENF ABRIK WINKLER, FALLEBT & 00., A. Gr., OF- BERN, SWITZERLAND, A CORPORATION OF SWITZERLAND LATE NEWS DEVICE FOR ROTARY PRINTING MACHINES Application filed November 30, 1928. Serial No. 322,707.

My invention relates to a late news device for rotary printing machines. The new feature of the invention consists in casting the stereo plate containing the late news between two tapering side ledges on the core of the casting box, and inplacing the cast plate to gether with the core in the printing device in such position that the push on said plate in printing keeps it tight on the core, while. after the printing is finished the plate can be easily separated from the core by displacement in. the opposite direction. The advantage obtained by this invention consists in making the plate of equal thickness throughout which assures good printing and absolutely tight fit of the plate on the core with a minimum margin which enables the late news columns to have exactly the same appearance as the normal columns of the paper. v

In the drawings illustrating my invention by way of example Fig. 1 shows the core in the mould or casting box in the position for casting a late news plate; Fig. 2 is a cross section through the core and plate; and F g. 3 a front view of the plate on the core.

The pot a, only a part of which is shown in Fig. 1, contains the molten metal used for casting the stereo plates. In the bottom of this pot a is provided a valve 1) with aperture b for regulating the flow of the molten metal out of the pot a into the casting box, this valve may be operated by any suitable means not shown. The box comprises a bed 0 in which lies the matrix cl from which a cast is to be made. This matrix is held by a lock 6 of usual construction. The other side of that the plate is castunder the head of molten,

metal in the pot' a and that after it is cast it is separated from the molten metal by turning the valve Z). Plates cast in this way do not require any solid head, so that the plate can remain on the core, and this core can serve as fudge box- The margins 2', am so small that the late news columns need not be reduced in thickness even in such cases where the nvention 1s applied to existing late news devices.

What I claim and desire to secure by Letters Patent of theUnited States is: p

In a rotary printing press, a segmento-cylindrically shaped plate holder having a plate holding channel therein, said channel being tapered in a direction opposite to the direction of rotation of said rotary press.

In testimony whereof I have signed my name to this specification.

. C. WVINKLER.

the mould is formed by a core fwhich has I ledges g, h at the sides which taper from one end to the other, so that the space between them has a wedge shape. These ledges g, h are undercut. l

The core 7 can be held inthe casting box by angle pieces Z and m, as shown in Figures 1 and 2, fastened by bolts through a large metal core n and fitting over bevelled edges 0 and p of the small core 7. In order to remove the core 7" it is only necessary to open the casting box in the manner usual in such machines by letting down the bed 0, whereupon the bolts holding the angle pieces Z and
