Talk:Bender Machine Works
Cites? What cites?
This article is going to remain a mess for a while. Sorry, but it's not something I can do much about.
I need to find some historical sources, and if you google this, there is just NOTHING out there. Mostly what you will find is messages from me and other people looking for them.
I may have to do research of old farming newspaper articles or see if a magazine with a long history like Hoard's Dairyman has a historical archive that I could access.
Bender milk receiver / different company
It appears the washer/releaser and the milk dumping station may be separate devices, possibly invented by different people but used together..
I have heard people call the Step Saver a Bender device. It appears the two may have been often used together, so the brand names got all mixed up over the years by farmers using the equipment.
Here are all possible patents related to Lloyd Bender and/or the Bender Machine Works that I've been able to find, using http://www.freepatentsonline.com ... I also opened each of these patents to check the patent citations to previous inventors.
Unfortunately none of these show the step saver as I have always understood it, with the conical bottom and float ball. More research is needed apparently.

Dumping station research
Milk dumping stations / milk transfer carts
Still, nothing specific is turning up, but I will keep looking. Several promising patents with a float ball, but none with the ball loose inside as in the typical Step Saver cart... odd, that it is so hard to find.
