Patented in the German Empire on November 15, 1908.

The invention relates to a device for reading a printed or written. Strip that is applied by hand or mechanically within a container by means of rollers. and is unrollable and visible through a viewing opening.

The characteristic novelty feature of the subject matter of the invention is that the Strip is passed between two inspection openings.

In the drawing, the subject matter of the invention is, for example, in one embodiment shown:

Fig. 1 is a longitudinal section of the device along the line AB of Fig. 2;

Fig. 2 is a front view, partly in section.

The entire content of a book is no longer on individual sheets as it was before printed, stapled, bound, cut open and turned over individually while reading must be, but on a continuous strip of tough paper, canvas o. The like., which is firmly rolled up on a roll and by pinching the end in a slot and adhesive is connected to the same. Such a role 1, the is provided on the sides with circular guide washers 2, 3, when not in use lifted with the rolled up and printed paper strip 4 in a container or in the name and table of contents of the work concerned.

The roller 1 is mounted in the housing 7 by means of its extension pins 5, 6 and is provided with a cover 10 which can be folded around a hinge 8 and can be closed by button springs 9, as well as a handle 11 for convenient carrying or hanging. Housing 7 and cover 10 form an upper and a lower hollow cylinder 12, 13 with intermediate frames 14, 14 ″, which on both sides carry viewing disks 15, 16 of an expediently rectangular shape. Between these disks 15, 16 and over the guide rollers 17, 18 and Ι7 ^α , i8 <* the reading strip 4 runs.

In the upper cylinder 12 of the housing 7, a rotatable roller 21 provided with circular peripheral disks 19, 20 is stationary arranged. Outside the housing 7 are foldable rollers 1 and 21 Handles 22, 23 attached.

The interchangeable roller 1 engages with its one pin 5 in a corresponding bearing of the hollow cylinder 13 and with its other pin 6 in a slot 24 of the spring bolt 25, which is pressed inward by the spring 26 and attached to the outer handle 23 is, whereby an insertion of the roll 1 in the lower hollow cylinder 13 is made possible.

As soon as the roll 1 is inserted and the strip 4 with its free outer end is inserted into the corresponding slot of the roller 21, the unwinding in the Way causes that after the lid 10 is closed, the handle 22 and therefore the roller 21 is turned to the right until the writing to be read appears under the display window 15, whereupon one continues to turn at the speed required for reading. Is as-

Claims (1)

then the entire strip 4 is wound onto the roll 21 during reading, the device is rotated 180 ° in such a way that the previously lower cylinder 13 goes up and the previously 5 upper cylinder 12 goes down. Now you turn the handle 23, ie. thus also the roll ι zvangschlüssig connected to it clockwise, whereby the continuation of the writing appears under the sight glass 16 and the strip 4 is wound onto the roll 1 via rolls τη ^α , ΐδ- ¹ from the roll 21. To close the viewing panes 15, 16, small roller blinds can be arranged in the frame 14. Pate ν T-A NSPRU c η: Device for reading a printed or written strip by means of Rolls within a container can be rolled up and down manually or mechanically and is visible through an inspection opening, characterized in that the strip is passed between two inspection openings will. 1 sheet of drawings.
