With the previous lever coping presses, the lever on the upper movable Prefsplatte works, a special adjustment device is necessary to adjust the Prefsplatte to the thickness of the Kopirbuches to be able to adjust, since the movement, which the Prefsplatte by the leverage learns one is too small to be readily available for any book thickness or for any desired Sufficient pressure.

The present invention now relates to one of the accompanying drawings in various Embodiments shown press, in which the aforementioned adjusting device is not required by having both the copy book between them after this establishment receiving Prefsplatten against each other and are movable from each other.

In the Construction Fig. Ia, 2a and 3a, the Prefsplatten α α ¹ attached to the horizontally guided in the bearing blocks ff ¹ push rods dd ¹ , and a lever h and act on each plate. h ¹ , which, on the bolt \ resp. % ^l rotatable, engages with the upper arm around a cross pin e e ^{1 of} the push rod d ; the lower arm stands with a corresponding rounding or with a roller mm ¹ attached to the end in an eccentric slot s respectively. -s ^l , Fig. 2a and 3a, of the fixed base plate g, on which the entire upper part of the press standing on the plate g ^l can be rotated about the bolt k. With this means of the handles g ² g ² rotation executed slide the lower lever ends of hh \ as shown in Fig. 3a seen in the slots s BEZW. s ¹ and are more and more pressed off by the eccentric position of the slots from the center of the pivot pin k and so the upper lever arms BEZW. the Prefsplatten α α ^{1 moved} towards each other, whereby they exert pressure on the copy book between them. Since both plates perform the movement, so much movement is achieved between them that books of various thicknesses can be sufficiently pressed; it is therefore not necessary to set the plates to a specific distance. On Erdem granted the facility because the opening between the ^l> Prefsplatten on three sides is gone completely free, the advantages, that the Kopirbuch can be easily implemented and not BEZW so easily repelled to the outward edges. is damaged, as is the case with the presses with brackets. The inlays used for copying (oil sheets, etc.) also remain in better condition as before, because in the free opening of the Prefsplatten the edges can no longer occur.

The preparation of the copy book for the actual copy process, i.e. H. the moistening of the sheets, inserting the letter to be copied, etc. and also with the screw spindle Kopir-. presses outside the copier press. ■ ./&. ■■ took and then inserted the copy book in the press or. taken out again will. In addition to the press, a free space on the table is required on which

chem the copy book during the preparation Can find space.

With the above-described arrangement and movement of the prefolding plates, the copy press can now be set up in such a way that the copy book remains in contact with the press even during the preparation of the same, i.e. during the entire work of copying, so that the book can be transported into the press and is omitted from the same. To achieve this, either, as generally indicated in FIG. Punctured, the Prefsplatten α α ¹ by the horizontal mounting plates BEZW t. t ^{1 formed} a support table for the copy book, or the Prefsplatten, as illustrated in the drawing Fig. Ib and 2b, each around a hinge pin 0 respectively. o ¹ on the upper arm of the lever h respectively. h ¹ mounted so that it can be rotated so that when the plates are turned over they produce a table on which the copy book can be prepared before pressing. So that in this rotatable arrangement, for which a further example in Figs. 1, 2 and 3 is shown with a different type of movement of the Prefsplatten, these plates in the horizontal position Fig. 1 respectively. ib can be brought, the same are designed like a comb at the lower end (Fig. 3 and 2 b) and the combs of one plate offset from those of the other so that they mutually enter the gaps when the plates are rotated, whereby a coalescence of the lower ends of the plates, as they go into each other with the combs, is avoided. In the folded-over state, the plates then represent a closed surface, as illustrated in dotted lines in FIG. 3. ib then closed and at the same time a downward pressure is exerted with the spine on the plates αa ^l at the point where the combs interlock, the more the book is in a vertical position, the more the plates turn. is pressed down, also vertically against the book cover and then take the respectively in Fig. 1. ib dotted position. In order to carry out the pressing, the two plates can now be moved towards one another, as has already been described above for the construction Fig. Ia, 2a, 3a, ib and 2b. In the device Fig. Ι to 3, the plates rotate aa ¹ to ο ο ¹ on the push rods dd ¹ , which are respectively in the bushes c. c ^l the lever hh ^{l can} move. The said bushings rest rotatably in the brackets f standing on the base plate g and are held at the rear by the attached adjusting rings b . To guide the push rods d to prevent them from rotating, the same are on a rag / bezw. Z ¹ with the guide pin i respectively sliding in the head wall of the trestles. z ' ¹ provided. The movement of each push rod into and out of the lever bushing causes a worm gear s and a worm gear of equivalent value, which is cut into the bushing, the slots ss \ FIG. s \ in which a pin attached to the push rod m respectively. m ¹ engages; So if the levers on the common handle r are moved upwards, the rotation of the bushing and the corresponding pitch of the worm gear will push the push rods forward. moving the prefs plates against each other.

In the device of Fig. 4, the prefs plates being attached to the pressure bolt like the one shown in Fig. 1a, the movement of the plates takes place in the same way as just described, only that the levers hh ^{1 are} moved outwards so that they pass the outer table edges of if ¹ when lifting. To prepare the book, the same lies on the table tops tt ¹ with this device and is lowered between the pressure plates after closing; then the pressing takes place, and after the book has been lifted it can easily be laid open again on the table top.

In FIGS. 5, 6, 7 and 8 two devices of presses with rotatable table or press plates are illustrated, whereby a stronger pressure can be exerted on the copy book, and this is achieved with the device in FIGS. 5 and 6 , that the upper part of the press g ¹ goes on a screw s ¹ , which is arranged in place of the connecting bolt k , and that the lever arms h move with the lower ends u on the inclined surfaces s ^{3 of} a shoe s ² when the upper part g ¹ rotated downwards on the screw s ^{1 respectively.} is screwed deeper. Here the shoe, which embraces the lever ends between the tabs s ^4, rotates on the lower part of the screw s ¹ , and the more g ^l is unscrewed, the lever ends μ diverge from one another, i.e. the press plates against one another. When the upper part is turned back, the levers are moved back together by springs placed behind the lower ends of the same, ie they are always pressed onto the inclined surfaces s ^{3 of} the shoe s *.

In the construction of Figs. 7 and 8 the pressure is increased because the eccentric slits s are arranged in the form of a spiral in the lower plate g ; In this spiral go the end pin u, the lever h, and since the same can be given a slight slope, so are accordingly

When the upper part g 'is rotated, the prefolding plates are moved together with greater force.
