7. Horizontal movement of the P.U.arm for 7” = 17.5 cm discs [45rpm]
As already known, we must play for gramo. phonographs with a diameter of 7 "the diameter slide in
the7 "
This will now also take the small guide/ steering hook (

)

[this ASSOCIATED plate has the
deformed/bent post that needs repair!] repaired /formed nov 9 2018 test OK..
​
into the process and we
will now start from the moment the P U arm is moved from the inside out, which takes place in the
normal way already described.
​
The control disc rotates at a constant speed and now touches the small
steering hook
​
, which rotates around its axis.The steel wire spring (FIG 9

​
)
​
attached to the end of this
steering hook touches a
​
pin
​
on the GUIDE/steering hook (

).
​
this starts to rotate, which causes
the

handleba

r and therefore also the PU arm to move further in. This difference in rotation is
determined by the distance
​
(X). (fig.9
​
) The roller turns

small handlebar from the inside to the
outside and leaves at a given moment the small steering hook, which shoots back under the influence of
the torsion spring (FIG 9

​
) and bumps against the diameter shifter, but now also the large steering
hook is no longer swiveled and the PU is
just above the beginning of a 7 "plate, because the distance of the P.U. is greater than that of 25 cm
(10") plates and the times used are almost the same, the speed for both
