Small pumping house (Water)

[Mole Man]

Found this place just north of Kingly Vale, just off a foot path. I think it is some sort of water pumping place as it in the bottom of a small valley, and looking at the pictures inside, there is also what looks like a large water tank a short way from here, the pit was about 6 feet deep. I think the roof looks great and the old wheels and belts inside. Nothing overwhelming but just a nice little place, if anyone wants to go there PM me and I will give you a grid reference.

The pictures of the well are not related to the first ones this was just something I came across on the way there.

That's fabulous, Mole. Love seeing the machinery still in place...plus all the rusty bits and bobs. Cute well.
That reminds me that I've still got a pumping house to post up sometime...I'd forgotten about that!
Cheers

Thanks for the comments Foxylady, have just put up another picture of the roof from the inside which look good, as I had two cameras with me today, and only just look at the point & shot one.

Jeez that's nice.

Washed out paint on the walls, lovely windows, pumps, spares, spiders webs, gears and best of all a gorgeous old electric motor. What a find! I want to live there!!

I'm surprised all this has been left behind - we've never been so lucky on our jaunts up here.

Excellent find and good work.

What a cracking find, thats some interesting reduction gearing ,i've never seen a gear wheel with those "chevron" teeth on it before,I wonder who built it,was there any names cast into the wheels ?

 

[Mole Man]

Did not see any names on the wheels, but then I didn’t really look, was a quick trip this morning before I was dragged off shopping, will get out there again sometime and have a look and go down into the pit bit. I do know of another two places like this must get out to them some time.

This type of gear tooth form is very common where the gearing is subjected to varying loadings, and the gearwheels are cast iron. The type of water pump illustrated, produces vastly differing loads between the downwards and upwards stroke. With the gear ratio used, the large pump drive gear would only rotate very slowly, thus there would be quite a bit of 'chatter' produced in the geartrain if straight cut gears were used. This would lead to premature wear and tooth breakage, so the illustrated gearform would be used to alleviate this problem.

Yes,that would make sense when you think about it like that,well done D. S

If you do go down please be careful mate,there's likely to be a well under "floor" of the pit !

 

[Mole Man]

Looking down into the pit, it looks like there is about a 6 inch bore hole that the water comes up from, but yes will be careful, there is a steel ladder bolted to one of the walls to get down there.

Nice building

Herringbone gears, also used on steel gears. Single helical gears are used to have two or more teeth taking the load but suffer from axial thrust which has to be taken by a thrust bearing.
The herringbone design negates the end thrust and is much quieter in operation.
The small oil cup on the pump connecting rod would have had a cotton wick feeding oil to the bearing.

The double helical gear was invented by M. Citroen founder of citroen cars, and the distictive pattern of the gears was adopted as the companys logo.

Not sure what the magnitude of load variation on this particular pump would be as most of the "Down hole" mass is balanced by the counterweight fitted to the large gearwheel.
