Hi All, Always tinkered with various, old mechanical things. First time with an Edison phonograph. I need some advise on the winding mechanism. I haven't taken anything apart yet because I like to do some research first. When you wind the machine, and hold the crank, everything works fine. However, it wants to unwind from the crank. If you get it just right, it will hold. but mostly the crank just wants to spin in the wrong direction. I assume there is a ratchet and pawl setup. Could someone please point me in the right direction on how to do the repair? Or a schematic of the mechanism? Also, the cloth on the front is missing. Is there a certain color and material that is correct? I thank you in advance for any information. Frank

There were two styles of winding mechanisms on the Diamond Disc machines: some have the anchor pawl and ratchet, while others use a coil spring that fits around the winding shaft, and holds it by friction.
By what you describe, your S-19 may have the latter arrangement: I have experienced similar problems with my Amberola 30. It may be that the winding shaft is worn, or the spring has weakened: the best way to remedy this is to replace the spring with one of very slightly smaller diameter, so that it will grip the shaft properly.
The ratchet and pawl mechanism if you have one (I do on my s 19 could be worn, or the spring my be broken or unatached.this can happen due to over winding as was the case on mine when I got it. (And again when I did it myself, that's another story). If it helps I can post some pictures for you . I am working on a Chilton s like doc for the s 19 that I will free source when I get mine running.

I am also a newbie when it comes to the S19 and I have a similar problem. The shaft spring is disconnected because the tip is broken off. However my real question is: Are these springs held in place by friction? I see no mechanism to hold it in place once it is hooked into the locking tooth.
