discs fall onto the

shaver

of the pin, with which they are thus returned to the original position. The
mechanism is suspended with leaf springs to absorb the shock of the falling package of discs.

The high axle on which the P.U.arm is attached forms a whole with the steering hook
​
(fig 9. 111
​
). The
hori. zonal movements of
​
the
​
hook are made and therefore also by the P.U.arm. In the control disc
there is a component combination, (which will be called in the next "roll"), which can slide back and
forth in a radially oriented slot (fig 9.
​
130 - 137
​
). The
​
fork-shaped
​
steering hook is hit by this roller when
the control disc is running. For example, the steering hook (and thus the P.U.arm) is moved in after a
disc has fallen. If the P U arm is lowered again, the needle must end up on the edge of a 25 cm (
​
10 "
​
)
plate, the turning of the steering hook will take place in the same way, on the understanding that the
roller (
​
137
​
) against the other leg of the fork, for 30 cm (
​
12 "
​
) plates the process is carried out in the same
way,
​
only in the following way
the P.U.arm is turned in too much. When a 30 cm (12 ") plate falls, it touches the probe (
​
E fig.3).
Because it is retracted, the steering hook is blocked so that the needle lands on the beginning of a 30
cm plate. the control disc now slides in through the radial slot, and is led out again through the
crescent-shaped
​
plate (A fig.9).
The
​
palp/
​
is
​
brought back to the 10”/25 cm position
​
by the fin/

6. ​ Horizontal movements of the pick-up arm for 25 and 30cm discs
The hollow shaft on which the pick-up arm is fixed forms a whole with the
​
guide hook
(111 fig 9.) The horizontal movements of the
​
hook
​
are also followed by the pick-up
arm. In the control disk is a set of spare parts (130-137) (which will be named "roll"
in the following), which can slide back and forth in a groove directed radially, the
hook
​
of fork guidance is achieved by this roller when the control disk rotates. The
guide
​
hook
​
(and consequently the pick-up arm) then move inwards when a disc has
fallen. If the pick-up arm falls down again, the needle should coincide with the edge
of a 10”/25 cm disc.
The rotation of the guide
​
hook
​
to the outside is analogous, it being understood that
the roller (137) now presses against the other branch of the
​
fork
​
. For 30 cm discs the
process is the same, with this difference being
​
avoided
​
in the following way that the
pick-up arm is placed too much inside. When a 30 cm disc falls, it touches
​
the
​
palp
(E fig 9).[

As it is pushed back, the guide
​
hook
​
is blocked, so that the needle is at the
beginning of a 30 cm disc. The roll of the control disk then moves. towards the inside
in the radial groove, but is then guided outward again by the
​
half-moon
​
plate
​
(A,
Fig. 9).
