1926 Shearer Harvester #4

This is a sub-page documenting the restoration project of my Harvester.

The purpose of the elevators is two fold, hence the need for two boxes. All the harvested material goes into the shaker box for agitation and screening. The product then falls through to the bottom and if it is clean, ie no bits of stem still attached, gets to the main box pick-up which is the vertical or forward box. If there are still bits stuck to it, it won't pass through the screen and goes to the secondary pick-up and then through the thrasher again via the secondary or rearward box.

I took all shafts and pulleys out of the boxes and laid them out.

Then I placed the empty boxes back on the machine just to see how they sat.

To remake the boxes I drew them on AutoCAD after measuring out the hole spacings and dimensions (in impreial units) and then took the DXF files to a place that I used to work at, Floveyor Pty. Ltd. Bayswater and they NC Punch pressed them out of flat sheet. They also bent them up (to form a box) then I set about adding new timber, riveting them together and installing new belt and buckets.

Having a breather, after I was given a seat by Ken Turner of Wagin, Western Australia. Although the seat was from a Sunshine, I have now got a genuine seat from a Shearer. The Sunshine seats are pressed metal, whereas the Shearer seats are cast metal.

A new screwfeeder was made by punching 1050 (25.4mm x 2.2mm rectangular holes) in a flat sheet then rolling it into a cylinder and placing it inside another half cylinder with a slot in the bottom to let the waste undersize out, and a rectangular hole in the end to let grain out. Inside the inner cylinder (the rotating sieve) is a set of flights to push the grain through. The undersize falls through while the good grain makes it all the way through.

This concludes the rebuild of the Elevator boxes for now. Later I will replace the scoops at the bottom of the two boxes.
