Dalton Six B-4 Lot 5 # 247

 

I recently purchased a Dalton lathe from a watch maker who looked as old as the lathe. He explained to me his friend owned it and left it at his shop when he decided to pick up and retire in France. Go Figure. It comes with no other gears but seems to be in pretty good shape. I am confused on a couple things. First, what is the purpose of the water spigot/star knob on the x carriage? when turned, it moves the the carriage but it seems to be in a bad spot and the larger wheel to its left preforms the same function. My second questions pertains to the lever at the top near the pully drives. When pulled, this lever seems to lock up the spindle and move a sleeve toward the stepped pulleys. What is the purpose? Is it to allow for belt maneuvers??

I would like to know the apprx age of the machine. Last patent date is 1917. Also, this lathe will be used in production to make small parts.?
I am very impressed with the machines design. Being a submersible engineer, i have seen well thought out designs as well as very poor designs and this machine is very well designed for ease of use and adjustment.?

Thank you for the help,
Jon

Lathe was bought and is located in Melbourne Florida?

Hi Jon,
?That knob is actually a clutch knob I think but it's stuck. My brother had a Dalton TL which had a knob like that (I think, but it may have been a different lathe) and we had to carefully disassemble it to get it useable. If you can spray a little Kroil in the mechanism from both the front and the back and let it sit a few days you may be able to loosen the knob (Lefty loosy I think) and once there is a slight gap at the front hit it with a brass hammer.
?But you may have to heat it all up with a propane torch. My brother and I took the apron off which is pretty easy and we were confident we aeren't going to break anything, and if a few mild raps with the brass hammer didn't loosen it that would be my next step.
?It has a cone that fits inside a cone as a clutch, just like a SB.

Hi Jon,

The knob on the X carriage is to move the compound rest. You can use it to cut tapers and angles.?

The lever is to activate what's called the back gears. You pull the pin on the right side of the pulley assembly forward, then engage the gears and it greatly reduces your RPM. This gives you more torque and makes cutting operations on larger diameters easier. The "Six" in Dalton Six refers to having six speeds, 3 pulleys in high and low.

Glen, after reading your post I turned the large wheel on the x carriage while holding the clutch knob and it freed up. It now preforms as a clutch should. Thank you for the information!
 

I see. With it functioning now i will have to play with it.?

John i just pulled the pin on the pulley and engaged the back gears. Works exactly as you stated, increases torque tremendously.?

On a side note, I watched a youtube video of a man engaging the carriage screw lever. Yep i know i an way off in terminology. let me reexplain. The lever that you would engage if you where going to cut threads into a rod. It moves the carriage at a constant rate of speed.? When he did this it made a terrible noise of gears grinding. Is this normal? or did he have the rpm too high??

here is the video:??https://www.youtube.com/watch?v=VoSyFJiY4B8
