Looking at that LONG flat belt keeping the steam boiler well away from the pile of dried grain stalks makes me wonder, How many times that caught that pile on fire before they went to the LONG belt?

I like that tractor!!!
Thanks hemmjo, I wondered about long belt every time I have seen this or similar pictures.

Although you can't tell by their faces, I would bet those workers were happy to get to wear their Sunday best for the photo...
Morgan is still around after 152 years... they made big guns for the Spanish American War:https://www.youtube.com/watch?v=TGsc...ature=emb_logo
It's great how Morgan seamlessly switched from steam to electricity...
In reference to photo #2000 and the short discussion following; Today is the birthday of John Froelich, inventor of the gas-powered tractor.
His inspiration came from the fires caused by steam powered threshing machines.

so who invented the spark arrestor!!!for the tractor of coarse.

I think those are heaters not stoves...
I thought furnaces..
They were also known as oil stoves back in the day. My dad used to sell and service them in his hardware store. I grew up helping him in those days. I remember those nail kegs shown in the picture as well. I miss the old days.

Looks like they gave the mallet to the correct man.
I noticed him too, looks to be almost 2x as big as the others. he may be with the adjustment team...or be the team

Now you carry way more computing power around in your pocket, or even strapped to your wrist.
na, thats the old suncity recording studio,:rimshot: it's only rock&roll !!! and of coarse we also have cameras&recording studios in out pockets too.:popcorn:
Although I have one, it's nice to not need an oscilloscope to be on the computer...
Notice the absence of CRT displays or PC keyboards. Today's generation would be as lost in that room as if they walked into an alien spaceship. Writing software on punch cards and troubleshooting your program from the printout of errors was challenging and required many hours. But I certainly learned a lot about computer logic during those days.
The operators console has a keyboard, but it's not visible in that picture. Output was the teletype next to the woman on the right. The oscilloscop was for monitoring up to 1000 memory locations. Per Wikipedia :Quote:

Way back in the 1970s head guy walked into the computer room, I was sitting in front of the ASR-33 punching a program onto paper tape. He looked at it and said "WOW, THAT'S FAST!!!"
Almost had a fist fight, we'd been working since the previous day..most of the time waiting for that "fast" machine.
A note from back then, the optional cup-holder that mounted on the upper right of the ASR-33 was right over the hot power supply so it was better for coffee rather than beer...err...soda.
When I was a computer (Data Systems) Tech — late '60's, aboard the USS Ranger (CVA-61), in the IOIC/flight ops secured space, of the Operations Dept — the lead-lined, 642-alpha and bravo Univacs we worked on, were 7' tall, 5' wide, x3' deep. Chill-water cooled, with 30-bit registers, and hard-wired, iron-core matrix memories (one each). They clocked in mega-cycles! And the bravo was a computer assisted, 'cleaned-up' version of the alpha — mainly to do with redundant memory addressing logic — and could do square roots. (can you imagine!)
One thing computers do really well is iterating a simple arithmetic equation very fast. I don't know how it's done today but on at least one of the early breadboard computers I encountered capitalized on this by computing roots using Heron's method.
Heron's method for finding square roots is elegant and requires nothing more than the four basic arithmetic operations.
If x is less than the square root of N then N/x is greater than the square root so the average of the two will be closer to the true root. This leads to the iterative equation...
x[n+1] = (x[n] + N / x[n]) / 2
With even a poor starting guess of x[1] this will converge to the square root in a few iterations.
An example will demonstrate. Let's find the square root of 6 (for reference, my calculator says 2.44949). Six is between 4 (2 squared) and 9 (3 squared) so a reasonable guess for x1 might be 2.5. Then
x2 = (2.5 + 6/2.5)/2 = 2.45 (squared = 6.00250)
Very close but let's do one more iteration...
x3 = (2.45 + 6/2.45)/2 = 2.44949 (squared = 6.00000026)
which would be good enough for most purposes.
I can hear you saying, "Yeah, but you picked an initial guess that was very close to the actual value!" A valid objection so let's try it with an initial guess that's downright silly, 7. Remember, 7 squared is 49, and that's far enough from 6 that even a schoolkid would know it's not a good choice. In addition, the square root of a number can never be greater than the number so, since 7 is greater than 6, choosing it as a first guess is particularly dumb.
x2 = (7 + 6/7)/2 = 3.9286 (squared = 15.4339)
x3 = (3.9286 +6/3.9286)/2 = 2.7279 (squared = 7.4414)
x4 = (2.7279 + 6/2.7279)/2 = 2.4637 (squared = 6.0698)
x5 = (2.4637 + 6/2.4637)/2 = 2.4495 (squared = 6.00005)
close enough for the work I do. So, even with a laughable initial guess we got five significant figures in only four iterations. Clearly, one doesn't need to be a genius mathematician to make useful guesses.
you guys make my head hurt.. all my roots are round...well sort of round, not many n's or x's and a pain in the butt to dig up. I will say 1 additional thing.my pies are round. cakes go either way round square oblong, rectangle tangle and eaten up.

Not just reconditioning, might have been from wear or periodic maintenance, but neither beginning or wrap-up of job. Note date of picture; how much work passed through it, especially prior 5 some odd years? Imagine the plant capacity, diverting to other lines, with war production full tilt before shutting this one down for work. A safe bet is steel from this plant had been transported for use in every Allied country.Quote:

Like I have said several times, "check out the hats that everyone is wearing and not a hard hat in the house!
I agree totally!
I looks like they are starting to disassemble a temporary rail track that was used to move in, or move out a big casting that needs replaced or repaired. The track base is built up with wooden sleepers and then I-beam sleepers, probably to raise the tracks high enough to clear existing tracks?
perhaps those are custom hard hats..that look like reg hats...like the bronze dipped shews..or the osha guy dosent come till saturday.

heck just watching them make the steel for that would be awesome. it's truly amazing what we used to be abler to make before we had the 9002iso&whatnot bs qc came about.witch is like the carfox...used for selling nothing more.
