Hi all. I have tryed the search function, but must be doing something wrong. I'm looking for pictures and information about the all crop harvesters, any model, pulltype or sp. Preferably pics and info about the inside and workings of the machine.

These machines had what was called "grain bypass" which I think was an option on the later models and may have also been called "seperator bypass" not sure about that one though. That is one of the main things I am looking for info on at this time. It appears to have been a very creative concept and I wonder if it can be applied today.

Thanks for any help.

I'll look through my literature stash. The information I got from an older Allis Chalmers employee is that the all crop was designed by Curtis Baldwin when he worked for Rumely in LaPorte in 1928&1929. Baldwin worked at Savage Harvester in Denver when Rumely bought Savage. Then went to LaPorte for Rumely. Allis Chalmers bought Rumely in 1929 as they wanted the Dealer network and the newly designed AllCrop combine.

The historical society at Independence has most of the old Allis Chalmers paperwork now, atleast the majority that Allis didn't throw away when they moved the combine factory to Hesston. Alot of history was lost.

As far as I know the only model to be equipped with the grain bypass system is the model 90. It is a drop down behind the straw rack, directly behind the cylinder. There are long curved fingers that keep straw and other material on straw rack, but will allow some of the grain to go directly to the raddle chain below the straw rack. I own a model 90, so if you need any assistance or info, let me know.

The brochure I found online is of the model 90 with the grain bypass, just like you mention. There is no down beater behind the cylinder, correct? Also, what mechanism is used to get the grain from under the concave to the raddle chain?

Thanks for any help you can give. What crops do you harvest with yours, or have you restored it for show?

In all the pictures I see, it appears that the cylinder bars are simply formed like angle iron. Is this the only configuration?

Tom Yaz at www.yazallcrop.com knows a lot about the history and development of the All Crop Harvesters, too.

also if you arent on it go to www.allischalmers.com. they are a great wealth of info.

Correct, there is no beater behind the cylinder, just some curved fingers to keep the straw on the rack. The grain is thrown up in a high arc and some of it is allowed past the fingers into the grain bypass, the rest stays with the straw and falls through the rack to the raddle chain. I just purchased the model 90 this fall to add to my collection, it is is original mint shape. I wanted to try it in soybeans this fall, but because of things being rushed, we did them all with the F2. I also own a model 60A all-crop which is also in mint original shape, and i have harvested a few oats with it the past 3 years.

Thanks for the replies. I have, as time allows, been calling around the area finding phone numbers of folks that might know of one for sale etc. Nothing yet, but I think I know of an AC collector not too far away, just waiting for a friend to get back with his phone number.

Been readin Yaz's stuff for a while as I find it. Very good stuff. Looked around the allischalmers site, have'nt quite figured out the navigation there yet, but I will. Sure a neat picture on the home page of the AC site. While searching, I found both the Allis Chalmers Manufacturing. And the Allis Chalmers Company refered to.

We used to have a 60, that had a grain bypass on it. Every morning we would have to run a wire up it because it would plug up. That was on oats, we never did beans with it. The cylinder bars were just angle iron with a rubber coating on them. They were hard tho, I tried to saw one with a hacksaw once, took the teeth out of the saw. They might have some info on ebay.

The cyl bars run at a slight angle across the cyl,not straight and I believe the concave bars were 1/2 round rubber.Been too many years and dad took care of all that back then.

 

[gleanerf2]

Yes the bars are at an angle, and i think rubgber concaves, this is what gives the flexibility to harvest over 100 different types of crops

 

[doorknob]

Well, I finally have the phone number for the AC collector, I'll try calling it later on.

Here's a small section of the brochure that I found online somewhere. If you know where this came from, please tell me, as I have completely forgotten where I found it.

Dang c.r.s. is acting up again.

You can see like has been said here, the cylinder bars are spiralled a bit and angle iron type design. What I cant seem to find, is pictures or even explanation of the workings below the cylinder and concave. I'd apreciate any info you care to share about that part of the machine. I am curious how the material that falls through the concave gets to the raddle chain for carry to the cleaning system? Or,....is the concave even open design? Might only the back part of it be open to allow grain/seed through?

 

[dove]

The cylinder is a closed bottom design all material must go out the back of the cylinder. I ran one when I was a kid and remember being the one inside to change the cylinder bars. Good luck!

 

[gleanerf2]

Yes it is a closed concave, all material is thrown up in a high arc, and seperated by in the rack, and then it hits the raddle chain and is moved to the shoe.
