Geneva horn moving


Recommended Posts

Hello all,

 

 I have a Geneva Blake machine that’s I am trying to make operational. Currently, at one point in the cycle, the horn is getting turned by the machine. I assume this has something to do with the interior bearings, or perhaps the lock nut is too tight. Any advice on how to proceed with this repair would be greatly appreciated. 
 

Thank you,

 

Mr. Jameson

You may need a new whirl and pinion but take the cap off (2 screws) take them out and try running the machine without them, clean and inspect the teeth are ok (usually it is the teeth on the pinion are quite worn).  Plus check the universal joint in the elbow of the horn is ok and the screws are tight - hand tight not too tight as it will crack

Thanks for your reply,Peter. While not brand new, the pinion and the whirl look pretty good. turning the handwheel with them removed gives me the same result, the horn spins. I will check the u-joint. I guess it would be worth mentioning that even with the horn completely removed the turntable has a tendency to spin as well, though the weight of the horn seems to exacerbate the problem.
