To all Trix-friends!
Now all Trixmodels have to run by itself!
Untill now you have build several, you had to turn yourself. Now, the little
machines get, so to speak, their own build-in motor, which puts new life to it
and sets it in motion, that runs the wings of the windmill, the propeller of the
flying machine etc. The latest supplementary set Trix-Electro provides all of
this. It is so easy to handle, that you don't have to take care of difficult
rules, but can start immediately with building. All shown models are, in spite of
the diversity of applications, based on the same principle. And if you have
understood that, you can apply it everywhere and build much more.
164. Electric bell
If we connect the wires to a power supply, then the current is flowing as
follows:
From one pole through the spool to earth, then through the spring to the screw in
the insulating strip, back to the other pole.
As a result, the core of the spool becomes magnetic, as a consequence the
armature is pulled by the core, and then the spring is pulled away from the
contact screw. Then the current loop is disconnected and the armature
comes off and pulls back, the current loop is connected, etc.
170. Electric motor
170. Morse appliance
The illustration shows a spool, over which a big darning needle is hanging.
Swinging is possible between a dot and a dash on a piece of paper. On forehand
we prepared the darning needle in a special manner. We stitch it in the hole of
the spool, while this is under power of a battery or accu. (We can't use a
transformer in this case). The needle has now become a permanent magnet.
If we now connect our model to a D.C. source, then the needle pulls to one
side. If we exchange the connections, then the needle pulls to the other side.
We can let the needle move or to the dot or to the dash as we like and it
makes a splendid telegraph, because the Morse-Alphabeth consist only of both
this signs.
183. Telegraph apparatus
This machine works very much the same as a real Post-Telegraph apparatus.
If someone wants to send a telegram, the receiver is warned by a buzzer signal.
The receiver unreels a paper tape and this will be written with
Morse-signs confirm the current pulses send.
