I D this steering sector?

Anybody got an idea on this? I believe it's
a set of steering sector gears. Shown with
a spray can cap for size reference. Despite
its appearance I think it's new with new
bushings. It was with some other old car
parts in an old barn at my sister's. If it
helps I think it was an old Oliver farm. I
hate to scrap it. No marks except for
numeral 4 stamped on it

I can't help you with the steering gear parts, but I DO recognize the ''Model T'' Ammeter/switch panel and the ''Model T'' ignition ''timer''.
 
Both of those gears, if meshed together would be on the same axis which would certainly complicate any steering gearbox they might be stuffed in. I'd keep looking for a shaft with a worm gear on it that matches the sector gear.

One thing's for sure- they aint model ''T'' parts!
 
I believe the gear and sector could go together, the sole reason being that the sector is not cut to receive a worm gear. Other than that I dont know what the stuff is either.
 
Could be the blade-lifting drive for a road grader. The round gear could mesh with the sector, but
it could be shaft driven by a smaller worm gear and worm. The sector doesn't look like
a worm gear to me. But I suppose it would sort of work if the worm was set at an angle to the sector. That's how the gear hob is set to cut the spur gear teeth. Worm gears are usually made of copper alloy to reduce friction wear. A worm gear and worm can be made to mesh at various skew angles. The gear cutter is basically a copy of the worm made with tool steel to give it strength and cutting life. It has notches to form cutting edges.
