    By Jove, he's absolutely right, Ralph ! Sorry I sent you on a wild goose chase looking for the lockout shaft / lever.

    If you don't have one, I think you could make one easily enough. It just clamps the diff shaft and keeps it from turning.

    Hello Emanuel

    Sorry for my poor manners. I have been a member here for many years and have not felt I had much to contribute, so many smart people here. Therefore I have not visited much lately either. I was browsing through the other night and the title of this thread happened to catch my eye. As I am always interested in anything with gears involved I took a look and low and behold I thought I had some information that might help. So I posted in a hurry.

    As I said in my post I only have experience with two Barber-Colman machines. I have also ran a G&E hobber of 1940's vintage. It too has a similar lockout mechanism for the differential. However the two B&C machines were new enough that some of the controls are electrical, feed, hob spindle start and the like. You mention an engagement lever, did some of the older machines possibly use a lever instead of the link? Just curious.

    I have attached a picture, that is, if I did it correctly, seeing as it's my first time. It shows the link I am talking about. It is the red link in the picture attached to the differential drive shaft which has splines to mate with the change gears and the lockout link.

    Hello Emanuel

    Sorry for my poor manners. I got in a hurry because I thought I had an answer and was in a hurry to post. I am by no means a gear expert and hope I did not come off that way.

    I only have experience with the two B&C machines and a G&E machine. They all use a similar lockout mechanism. The B&C machines are new enough to have some of the functions controlled electrically. Is it possible some of the older machines used a lever lockout?

    I have attached a picture of the B&C lockout link in our machine. It is of course the red link between the differential and the intermediate stud.

    Hello Ralph

    Emanuel is correct, a complete book is as essential as the machine is! Especially for the differential.
