Could Someone ID This Bridgeport Power Feed For Me?

[Shootymacshootface]

I just got this mill handed down to me from my awesome father in law. I used it today for the first time, and I cannot believe how smooth and quiet this thing is! I'm not sure what model or generation this is either, anyone?
My main question here is this power feed that he gave me with it. He never used it. I just bench tested it and it also runs smooth and quiet, so I will begin installing it. I will need to pull out the lead screw to modify the right side to accept a 5/8 shaft. I would like to know more about it so that I can service it with the proper lubricants. This thing is really cool. It has a gearbox like an old lathe. Six gears with a high and low range, 12 speeds. It goes as fast as the Servo 150 on my FV1 and will go a bit slower and I am quite sure that it wouldn't stall going super slow, because it works with gear reduction. I was thinking of running just this on the static phase converter that he gave me. That way I could use the power feed without turning on the rotary. The tag with all of the info is completely illegible. Don't mind my bench set-up. Here are some pics!


Thanks in advance! This site is awesome!

That is an old gear driven powerfeed. Obsolete as all get out and the same 5 or 6 parts and gears go bad. It will be interesting to see how you make an extension shaft for the lead screw to work with the gear driven feed.

Amazing that you have both handles on it and they arent broken, its not common to find both of those. I have only ever seen one manual from Bridgeport with information on it, lemme see if I can find it.

My mill came with one. It works well, other than a couple of gears that sometimes slip. I avoid those and it gets the job done. There is an extension shaft that connects to the leadscrew, and has the thread for the manual handle on the other end. There is a pin that fits in that slot to drive the screw.

Very cool info everyone!
I found this power feed in an early 60's brochure on Vintage Machinery. There was no model given, just a description. It said that there is a clutch in it that will stop it if the cutting becomes too heavy. I guess that would also serve as a travel limit function as well, not that I would want to test it.
The brochure also said that it was available on all Bridgeport Mills, except the 48" model. I will measure my table, but I am pretty sure thats what I have. This thing is going on my mill.
I will measure the bolt pattern and the relating shaft position.

I just measured my table, it's 42".

Look at the pic of the start/stop handle linkage across the front of the table. One pic shows the stop setup. You would have to move the DRO X axis reader to the rear of the table to set the stop system up as original. I ran the mill in the pic for about 15 years........never had the clutch ever kick out.

Just for the record, I don't know, but to keep with standing protocols.
