Nissen Medart Platform Question

[rmcgann]

I have a old Nissen Medart platform. I have been unable to figure out what a fitting is used for on the back of the platform. It has a nut that fits over it. I would guess it is some type of grease fitting. But, it is threaded. So, It's not an amalgam or zerk fitting. If anyone knows what this is, Please let me know.

What I believe is supposed to be there is the lock down that is used to secure the platform once you have adjusted it to the proper height. Here is a photo of this part of the mechanism

You can see the small lever on the back side of it

Thank you for the response. I have attached an additional side picture. That includes the handle that locks the platform. The handle is secured with a carriage bolt. That has a small flat hex bolt that is tightened so the carriage bolt doesn't move when the handle is secured and released. The fitting I referenced is on the back-side upper portion of this attached picture. As strange as it sounds, once you remove the nut over the fitting, it almost looks like a slightly large tire valve stem.

Hmm, to be honest, I've only seen a few of these, didn't pay that close attention to these details. So I take it the threads don't look like NPT ones? It could be a lubrication point

[rmcgann]

I don't think the threads are NPT ones. The nut that goes over it is just a regular bolt nut. Also, the fitting is just like a regular bolt, it doesn't taper. I do think it is a lubrication point. But, not what I would traditionally think of as a grease point on a metal part because it isn't an amalgam or zerk fitting. I could always put the straw part of a can of WD-40 or lithium grease or something like that and shoot some thought the small hole. But, I was wondering if there was an antique fitting or something I'm not aware of. I included two additional picture attachments, I think they show a better profile of what I'm referencing.

I would have said a grease cup, (they come in many different sizes) but all the ones that I have used (and I have used a LOT of them) over the years have tapered NPT threads.

My guess is it is a stop to keep the platform from traveling past the highest point. The mechanism reminds me a lot of my drill press. Same style lockdown handle.

Bingo! That's it Rusty. Come to think of that's near identical to the setup on my great grandfather's post drill that my father has.

I've always wondered what it was, and it being a stop sounds correct. Ventanakaz, I have attached a picture of my platform setup. One again thank you all for the input, I appreciate it.

That's a nice looking platform

I'm a bit perplexed by this one.

Does the mechanism say Nissen Medart? The model of this style that I am familiar with only had the Medart name and date of 1912. The support arms are wood and the platform of a different design. Finally, it was not blue (perhaps that is not the original color). Is this a later model of the one I'm familiar with?

Interesting.

Looks like a copy of an earlier piece made by Medart.
