Vintage oilers - how do these operate?

Recommended Posts

I came across these vintage oilers and unsure of the markings and how to use.  There is an opening channel at the tip of the needle which I assume allows oil stored in the tube to flow.   

Thanks

They are called Glass Fountain Oilers.

 

Older watchmakers mostly use fountain oilers. They use the principles of capillary action to draw a small amount of oil out of the tube (like a fountain pen).

 

     not gravity or capillary,    with a rubber tube, in your mouth,  the was pushed oil into the jewel.  older jewelers concitered better than the pump style.   keep them,  they are valuable.  vin

Thank you for that helpful information that lead me to the NWCC Forum where I found this:  "To fill these oilers you need a small rubber hose that fits over the class tube. Place the hose on the end where the needle is,then place the other end in your oil bottle and suck on the hose. This will draw the oil into the glass tube. Don't fill the tube completely full. A small amount will last a long time. You can store the oiler laying flat in a dark place like a drawer of your watch bench."  Not sure how you "place the hose where the needle is...then place the other end in the oil bottle then suck on the hose"   I take this to mean suck on the glass tube to draw the oil into the tube? Agree? 

Edit:  Found this on WUS:  "In the past you could get glass "fountain" oilers. These are a blown glass tube with a very fine steel capillary in the end. They are about three inches long, and are filled by putting the tip down in an oil bottle and sucking on the open end of the tube. I have used these type oilers, but much prefer the control offered by a set of good dip oilers. "

  good show!   I have seen them in action.  the above safety  measures were not used  the glass tube was filled with oil.  you can see the oil fill the jewel.  just don't suck,   vin

    • The watch is only a month or so old from I tool it out of the box, so I have not opened it nor serviced it. But obviously it seems like the speed of the watch has changed. Also due to this weird reading on the timegrapher, something seems wrong. 
    • Hand in the air and waving wildly.....The NH36/4R36 movements ("A" suffix means Day & Date) hacks and winds whereas the  7S26 does neither.  I have wondered if they were interchangeable.  I have one untouched 4R36A couple of years old that is a daily driver keeping within a couple seconds since last weeks setting. There seems to be some disparity about the stems.  Most 7S26 watches have the 4 o'clock stem and 4R36 is at 3.  I have seen recent offerings with a stem at 3 o'clock which do not hack/wind.  Any clarification would be welcome.
    • its more the skill to be fair, ive seen people in the watch world make pieces with make shift tools. that was the mistake a few years ago i made, spent a load of money on tools, but was lacking the skill.   However... stunning piece of kit you have there, 
    • You have a milling attachment and a dividing plate, that's the base for making wheels and pinions. Hopefully the dividing plate has divisions that correspond to the parts you want to make. You will need basic (well, advanced) hand and bench tools any pro watchmaker would have. You will have to source cutters for your gear making. It is possible to make them but you would really need more complex equipment like a profile projector to do a decent job. You could layout the holes using the cross slide and milling attachment. Essentially you would have what the fellow at Adventures in Watchmaking blog has and he has gotten quite far in his project. It's taken him years but he's doing it. Some basic CAD software would be really helpful, as well as the Swiss NIHS norms book for designing your gearing.   Couple of observations- the cross slide doesn't appear to have a graduated thimble on one axis, and the other (and the one on the milling attachment) are quite small. It appears to be set up "German style", that is, the headstock is to be used on the right. See the cross slide. You can't just flip the top slide around usually. And, on some of these old German machines the slide screws are 0.75mm pitch, so it can get a little nuts keeping track of where you are. AND- they are sometimes left-hand threaded, to the motion to advance is reversed from 99.9% of all other lathes. All that said it is still useful stuff. A friend of mine had an old Lorch with left-handed 0.75mm screws on the slide and he made up large graduated discs with pointers mounted near the cranks to make it a little user friendly. I tried it a couple of times but years of normal-sense screws wouldn't allow my brain to wrap around the reversed-ness.
