The arms 4. may be suitably articulated, by means of joints ll capable of being clamped. As a consequence thereof, the range of these arms has been rendered adjustable within comparatively wide limits and the holding bar 3 may be adapted to any desired size of book.

The holding arms 1 and 2 have eachapa propriately been equipped with a slide 12, 13, capable of being adjusted in a longitudinal direction, the slides being held invposition by means of a guiding member, forinstance,

a bar 14; In theform shown the slides 12 and 13 are each provided with a rack for the purpose of changing the. distance between thetwo holding arms 1 and 2. A toothed wheel 17 is fitted with and actuated by means of a handle 18 and engages the racks 15wand16, with the result that by turningithe handle the distance between the two holding arms may be adaptedvto the height of the book beingheld in the reading deviceat the time;

By means of clamping screws 19, 20,.the holding arms 1 and 2 may be clamped on the bar 14. The bar 14. to-

gether with the toothed wheel 17 and handle 18 is rotatably mounted in a slide 22 by means of a stirrup 21 or the like and springs 23: are provided possessing the tendency of pressin'gthe holding arms 1 and 2 against the book a. However, by exercising pressure upon the handle18 in the direction of the arrow itwillkbepossibl e without any trouble whatsoever; to, swing the handle in the direction of the arrow H, whereby the holding arms arelifted off the book. Analogous v to the slideif, the slide 22. may be displaced instance, a bar-24 i Atthe end of the holding arm 1 a knifeshaped: part25 is mounted capable of being rotated-and swung about.

iIn connection therewith the knife-shaped part be made by means of a swivel bearor'm'ost preferably of cbonite or the like has been attached. This roller permits, on turning over the leaves, to pull out one leaf of the book from under the roller without damaging the leaf in any way. On the other hand, the roller holds down the leaves of the book and simultaneously the book itself, upon the base plate. 7

The modus operandi of the device is as follows:

I I For the purpose of turning over the leaves merely one leaf of the book is seized with one hand, for instance, at the point 30 and moved approximately in the direction of the arrow K, whereby the corner of the leaf may easily be removed from under the roller 29; "The'leaf is now turned over and pushed under the holding tongue 5. As soon as a fairnumber of leaveshave accumulated under, the holding tongues 5, vthe holding tongues are slightly lifted up by exercising pressure upon the handle 9 in the direction of the arrow F1, thereby causlng the turnedover and accumulated leaves to pass below the holding bar, being gripped again by the latter immediately'upon releasing the hanarrangement, for instance, by bars 31, 32,

33' and from what has been said in the foregoing it will easily be gathered, that in spite of the position of the book-the latter itself and also the separate leaves will be effectively held tight,- simultaneously rendering possible a turning over ofv the leaves with the aid of one handw I claim: I 4

3. A reading device, consisting. in combination of a base plateyholding means disposed upon one side of the base plate and capable of displacement in the direction of the book, an elastic holding member on the other side of the base plate for pressing the leaves of the other side of the open book againstthe base plate, a further elastic holding member on the last-mentioned side of the base plate; a knife-shaped part at the end of thislatter holding member slipping in between the leaves of the book and pressing the leaves below it againstthe base plate but on I the other hand leaving free the leaves of the book resting upon the knifeshaped part, a bar disposed perpendicularly v to the elastic holding members, slides connected with theelastic holdingmembers and mounted upon and displaceable along the bar, a slide displaceable in the direction of the book and supporting said bar and adjusting means for the purpose of changing the distance between said elastic holding memhers by displacing same along said bar.

4. reading device as claimed in claim 3, wherein the adjusting means for changing the distance between the elastic holding members includes racks rigidly connected with the slides, a manually operable pinion engaging the racks for the purpose of adjusting the slides along the bar.
