CLASS, !! ή bookbinding.

In the drawing, the apparatus, if it is new, is shown with full, if it is known, shown with broken lines.

The well-known part in this case is the wire stitching machine, which is followed by the following Facility is provided:

The upper part of the apparatus AA can be pushed back and forth in a guide on the frame BB. The inclined wall J rotatable about the joint g is adjustable and is shown in the drawing in the position in which it is located when the stapling of the first sheet of the book to be stapled is to be started.

The sheet to be stapled is denoted by D in the drawing, FIG. 1.

The stapling itself is now done in the following way:

The upper part of the apparatus AA is moved as far to the right as the wave K , to be described later in more detail, permits, Fig. 2, and the sheet to be stapled is placed in the manner shown in Fig. 1 of the drawing.

As soon as the lever N, which is connected to a pedal device, is pressed down by the pressure of the foot, the head C of the stapler lowers onto the sheet and presses a staple into it, thereby connecting it to the underlying band U .

At the same time as the lever N , however, the lever M, which is also connected to the said pedaling device and on which the ratchet h engaging in the ratchet wheel V is attached, is pulled down.

The locking hook h slides over the teeth of the wheel V during this movement.

During the backward movement of the lever N , the lever M is pulled up again by the weight R , the locking hook h pressing against a tooth of the wheel V and causing the same to rotate in part.

The toothed wheel P connected to the ratchet wheel V makes the same movement, and because it engages in the rack Q connected to the part AA , this part is pushed as far from right to left as one bracket should be removed from the other.

With the adjusting screw S , the distances between the individual brackets can be determined exactly as desired.

So that this shift does not take place as long as the head C is still lying on the sheet, which would necessarily cause it to tear, the lever M is held by the hook ζ until the head C moves away from the one below As far away as necessary.

When all the clamps intended for a bow have been fastened, the upper part AA of the apparatus is so far to the left that one half of the stapled bow D can be easily opened against the other half of it lying on the wall, and a new bow can now be opened in the same way can be placed and stapled, moving the device back to the right.

Here, the ratchet wheel F hits the thumb G pressed by the spring / against the same and fastened to the frame B and, as the part AA moves further, rotates in the direction indicated by an arrow until the thumb G leaves it again.

This movement of the ratchet wheel F is transmitted by means of the conical wheels Ji ' to the toothed wheels O located on the shaft H , which mesh with the toothed racks W in the form of a segment of a circle.

The latter are firmly connected to the wall J and is therefore pulled inward as far as the sheet of paper is thick when the wheel F rotates.

In order to be able to regulate this according to the unequal thickness of the different types of paper, the lever χ is attached.

If it is set so that the thumb G is higher, the wheel F must make a longer revolution; accordingly, the wall J is also moved further inwards, whereas when the thumb G is placed lower, the wall J recedes less.

This wall J , which is rotatable about point g , can also be arranged to be displaceable, namely in such a way that the angle of inclination at which the wall J is to the horizontal always remains one and the same during displacement, Figs. 4 and 5.

The wall J is firmly connected to the strut C and the round guide piece α in the shape of a triangle. It is attached to it by means of screws or in some other way. Rack d attached.

The guide pieces α are located inside the sleeves b, which serve to guide them during the back and forth movement and are firmly attached to the frame A.

The wide toothed wheel e , which is mounted on the frame A , engages in the toothed rack d , to which the movement of the ratchet wheel F is transmitted by means of a spur gear ratio.

The thumb G is located in a sleeve that can be adjusted higher and lower and in which it springs.

When part A is shifted on part B from left to right, wheel F is caused to rotate partially in the manner already described, which movement is transmitted to wheel e and through it to rack d, whereby a backward movement of the oblique standing wall / of the extent that corresponds to the paper thickness of the printed sheet in question.

In order to be able to regulate this movement according to the different paper thicknesses, the previously mentioned lever x is also used.

To ensure that the distribution is as even as possible of the individual staples on the entire spine of the book and one that is even due to this To achieve curvature of the latter, the brackets on the second arch are so far to the right, so that they are a little below that of the first and the third The brackets of the fourth sheet come to lie next to those of the second sheet again directly under that of the first arch, as can be seen from the sketch below:

s-

This is now made possible by the previously mentioned wave K.

In the longitudinal direction of the same, six grooves are milled, which wrap around them in a helical _{manner with a * / 6 twist.} These grooves are not the same, but of different lengths; the first is one bracket length shorter than the second, this again one bracket length shorter than the third, the fourth is the same length as the first, the fifth is the second and the sixth is the third.

The shaft K is rotatably mounted.

The thumb L , connected to part AA by a hinge, engages in a groove in the shaft K and, since the grooves are arranged in a helical manner, causes the same to make a partial rotation when the part AA moves from right to left. Against it lays down. on the movement of part AA from left to right, the thumb L is allowed to turn the joint so far that it can slide over the shaft K.

But the same is done by a spiral spring attached to it as soon as it hits the the next following nut hits, pressed into this.

The grooves do not run parallel to each other, but the end of the one lies with the beginning of the previous in a straight line, as shown in Fig. 3, representing the wave shows rolled up, can be seen.

As soon as the thumb Z enters the second groove at the end of the movement of the part AA from left to right, this gives the sign of the limit of this movement. The opposite movement now occurs and the stapling begins again in the manner described above.

Should the offset of the brackets be limited to only two arcs, as is the case with the Stapling on tape is necessary, a shaft, which is divided on this, is to be used.

The six grooves are only chosen in order to increase the incline of the individual grooves avoid.

- The wave T is used to receive the stuff respectively. Band U, which when stapled through

the flap υ is held in place and is given the necessary tension by the adjustable spring W ^1.
