Case Threshing Machine

[AZ GARY]

Attached are three pictures of this Case Threshing Machine 21x33 SN 400047. To us that seems like an odd size designation and the straw blower discharges at the front. This seems like two odd specifications on this machine and it has been nearly impossible to determine the year built and why the odd size. The turn gearing on the blower was cracked that is why it is in pieces
Thanks for any information.

Its a 1937 model, 21 x 33 refers to the cylinder size, 1335 threshers were sold that year, I do not quite understand your question on the blower discharging at the front? It can be turned any direction to discharge with rotation system you spoke of,

The front what you call the blower is where you put the straw into the thresher.

I think he means that, on the blower housing itself (surrounding the fan) the discharge where heads up is at the front of the housing rather than toward the rear of the machine

It does seem odd too me, but I don't know Case thrashers at all.

In the book 150 Years of JI Case it shows the smaller threshing machines having the blower positioned as yours is. Blower in that position started in 1916 according to the book.

Yes, that is what I mean it comes off the front part of the blower housing facing towards the front of the machine. Any particular reason for the odd size of 21x33, and would a machine this small more likely to be used on a specialty crop. It came from the Flagstaff AZ area where at one time they raised navy beans.
Thanks for the reply's

The cylinder width was 21". The straw rack and sieve size was 33". Threshing machines always had a wider cleaning area than the cylinder. The Case book states peanut threshers that size, so maybe edible beans only needed a small machine also. Those crops wouldn't have the volume of straw as small grains like wheat, oats or barley.

I found the peanut thresher in this size also but was thinking no peanuts in AZ,, like you said I would guess it was a bean thresher, I think I asked for some better pics of the whole machine to see how it was made to tell, I forgot they spoke of the sieve size on the threshers, my late Case thresher ops I was thinking listed the width and circumference of the cylinder but I must be thinking of the combines, thanks for the correction

 

[AZ GARY]

Thanks for all the input.I think it was originally used for beans as that was a crop raised in Flagstaff at one time. Another feature this machine has is a centrifugal drive on the feeder so when the machine slows down the feeder slows down or stops. Was this a common feature on threshers?

 

[Don Rudolph]

Your Case thresher was one of the smallest built. I think you are correct, it was more than likely used as a bean thresher. The centrifugal clutch on the feeder is a very common feature on newer designed threshing machines. It allowed for more uniform feeding at the proper cylinder speed and helped to eliminate plugging the cylinder. Don

It was mentioned the Case book had some information on this model of specialty thresher, is that information available on line or in a hard copy. I would like to get some actual Case printed materiel on it if possible.

 

[casecollectorsc]

In the book 150 years of JI Case it has a section on Case threshers.I have some manuals for specific Case threshers but none for one as small as yours. Google the book and see what comes up.

Wondering if the blower in that position was for the smaller machines to save on overall machine length: Thinking about the straw flow over the racks. With the conventional setup, it would have to drop off the racks to the front of the blower and circulate to the back and out - would require an extra blower radius of machine length. The way that machine's set up the straw path would fall of the racks and then move forward through the blower, saving a bit of length.

Just a thought. Can't think why else they'd do it, since it's not exactly a natural flow path.
