Springfield Illinois 1911
Cool pic. I'd hate to have the job of block & tackling stuff up to that 2nd floor. I see some power lines going into the smithy....hopefully they had some modern stuff like electric blowers & drill presses....and a light bulb or two.
Looks like a 4:1 B&T with the extra rope in through the window. A 6:1 or 8:1 would have been available, I'm sure. I started to write that you need stronger rope for the 6:1 or 8:1, but that's not true. Think about it.
I have a 4:1 I bought new at Monkey Wards in DeKalb, Ill, in 1964. Bought it to hoist a large cabinet to the second floor of the pre-1900 house we had just rented. Its tiny stairwell may not have been enclosed initially.
Looks like a 4x4 or 4x6 the 2nd floor block and tackle is attached to. Maybe an I beam?
Assumeing that the 4x6? is securely attached through the roof line I'm thinking that 1200 lbs would be its limit.
Any thoughts on weight limit?
Thanks for posting the Reo. They were a very fine car. Probably a 1908 or 1909 2-cylinder 18-20 HP. Great picture.
The size of the beam looks more like a 4x8 to me. If it was surfaced that would be 3 1/2" x 7 1/2". Assuming that the block is 3 1/2' from the building and the allowable bending stress in the wood beam is 2000 psi, that would calculate to an allowable total load on the beam of 1367# and if the tackle is a 4:1, then the max lifted load would be 1094# and the puller(s) would have to pull 273# (assuming no friction in the blocks).
If the beam was a full 4x6 then the allowable lifted load would be 800# and the pull would be 200# for a total load on the beam of 1000#.
Jim, where were you when I was doing my shop math homework back in 1947 ?
I used a 4 X 8 on my shop beam. I get really uncomfortable lifting more than about 300 lbs. with my ancient block and tackle. I usually park "Rusty" (my 1927 pickup) nearby to tie the rope off on if I want the part suspended.
In this photo Rusty wasn't nearby so the rope is tied off onto my lathe.
I started up and ran the engine on the '13 for the first time yesterday...SWEET! I might drive the car today if I can get the ancient radiator leaks under control!
I would guess that they would hook up a horse to the block and tackle to lift heavy loads. We did when we would lift stuff to the loft.
"...bending stress in the wood beam is 2000 psi..."
But Jim, being from the PNW, you assume Douglas Fir. Central Ill has oak and shagbark hickory they might use for a beam. Resilient hickory will sure take the load better.
Then, of course, you need to calculate the strength of the rafters, studs and stringers..
The hoist would be on a rail so they could roll the load inside, if they were doing heavy stuff.
They knew strengths early in the 20th Century:
Very nice Herb. I like them all.
The thin fenders on the last one are wood. most likely a '07. Also a brass band around the front of the hood to make it look like a radiator shell.
Who has the story of loading a bull in the back of a TT with a block & tackle?
That's all find and dandy but I like the spreader. It's all business--Note the single steel tractor seat at the font. I could use that wagon.
I'll try to "use up" my REO pictures today.
These two raced from NY to San Fransisco and back.
Wow! So many great pictures.
Thank you all.
Only the muddy "REO Mountaineer" made the cross country trip and back in 1905-1906 (12,600 miles according to a Warner Instrument odometer advertisement). The other cars are the locals.

Great pictures of 1 & 2 cylinder REO's. Besides model T,s we have a 1906 1 cyl. and a 1910 2 cyl. REO touring. One of the pictures looks like a 1910 touring (No Windshield or Top).
Enjoy 1 & 2 cylinder tours with the HCCA.
Please let me know if you ever want to part with your 1 & 2 cyl. REO pictures as I would be interested.
