Bleeding Machine

That's an awesome picture, It really does look like the instruments are bleeding!

I wonder what the calibration date on those tags were.

Nice contrast of colors. :)

Very interesting. One instrument roll has a large blue stain, the other has a large red stain. Perhaps one recorded in blue lines and the other in red lines, and the ink cartridges or whatever held the ink leaked after years of being shut down.

Nice contrast of colors, nice name for the pic and it looks like they are bleeding!!

but what were they measuring. .

BKW I think you're right.

Looks like whatever day it was shutdown, it was around 1:30 pm . . .

That really does look like blood... I love how vivid both of the colors are, though.

Intresting those colors look still bright.

Machine's bleed to you know.....very cool.

Doesn't Leeds and Northrup still exist?

I think they still do exist

A memorable photograph.

Flagator & Jackie B..... I think L&N got sold off and divided up with Honeywell and a few other companies.
If you look real close at the chart recorder on the bottom, you can see a Dymo Label that says Red Mils case expansion.. my guess is that it measured the thermal expansion of the turbine outer casing in thousandths of an inch (Mils). You have to keep an eye on that so the upper and lower halves stay about the same size.
The pens are like a felt tip marker and if the chart stops moving with the pen down, it bleeds onto the chart. (Hold a felt tip marker on a piece of paper and watch the ink stain grow).
It looks like the recorder on the top had 2 channels a blue and a red,,, notice the 2 vertical indicator on the right side.. the bottom one only had one channel.
The insides of these recorders are a maze of tiny gears and pulleys strung with what looks like 6Lb test fishing line and can cause you hours or frustration trying to get them lined up and calibrated.

I think that machine needs a tag

Joe's right, it needs a deficiency tag! The bleeding ink (or whatever...) makes for a great shot.

Much appreciated, Mitch! :)
