Hello To all, Well I’m back with another problem. . . . surprise ! ! !  I recently bought a Gem Model “B” phonograph. I took it apart, cleaned everything, replaced the spring (not easy) and reassembled it. It appears to run great. There is one thing that I’m thinking might be wrong. When I wind it and start it playing the crank also goes around. Everything I double check and reassemble looks okay but nothing will stop the handle from rotating. Is there something I’m missing? Is there a piece missing that I don’t know about? Or is it suppose to rotate as it plays? Once again thanks a million in advance for any assistance. Respectfully,  Tim O’D |

Tim,
I do not know about others-but I have a Gem key wind and if I leave the key in place it goes around too-so I think you might be alright.

I think most machines which have an open spring (no spring barrel) will allow the crank/key to turn backwards while playing. I can't think of one of any brand that doesn't actually.

Tim,
The crank on your B shouldn't turn as it winds down like the key on the earlier A. The crank should be able to be pushed in to engage the winding gears, otherwise it should spin freely when disengaged from the gears.
Can you take a picture of the motor and winding assembly? This can probably tell if something's not right.

First I want to thank everyone for the replies  Now to try to answer them. I think I know what you are talking about when you say to push the crank in to engage the winding mechanism. I don't know if my Model "B" is different of what but the crank on mine requires you to screw the crank into the winding shaft, which appears to be always engaged. The main shaft does not move either in or out. I took a couple pictures to try and show you but for the life of me I can’t remember how to attach them of find any link for it . . . Sorry . . .  Thanks, Tim O'D |

Thanks, Tim O'D Hi Tim, There are a few free imaging sites out there, Photobucket( which I use) and ImageShack to name a few. Where is your speed control knob located? Is it on the left side, front lower right or right side of the machine if the horn is facing you? I'm wondering if a crank was "added" to an A at some point. Bill |

I think you may be missing the spring which disengages the winding shaft when you let go of the crank. This is a coil spring which is situated around the winding shaft and which pushes the winding shaft gear out of engagement with the spring shaft gear. In other words, the winding shaft is made to slide back and forth (gears in and out of engagement) within the motor frame. This allows the crank to hang free and not rotate while the machine is playing. Although the crank does screw into the winding shaft, it is designed to be permanently screwed in. Hope this helps,
Jim
