Does Anyone Own A Wain-Roy Stabilizing Apparatus?

According to one of the authors of Wain-Roy And The Invention Of The Backhoe they were produced and went through a couple of changes. Judging by the drawing below it is the later revision that had the bars underneath to relieve the stress from the transmission housing. What other front axle mounted or front end stabilizers have you seen for the tractor mounted backhoes?

A couple of thoughts:
Most tractor mounted back hoes I've seen
have a heavy sub frame that carry most of
the load between rear and front to avoid
the stresses to the tractor chassis.
Basically, the tractor just sits in a
cradel and supplys the power.
Most operators use not only the hoe's
outriggers to lift the rear end but also
lift the front end with the loader bucket.
So that Wain Roy device is not needed.
Here's a couple of photos of Ford backhoe
tractors that show the sub frame.

This is a 4500 that shows the sub frame
quite well.



Here is an older one. An 1801.
Board member Royse has one of these.





As for Wain Roy "inventing" the backhoe I
would say that is a little misleading
though I admit they did a lot of pioneering
work on the modern TLB
(tractor/loader/backhoe)
Backhoes have been around for well over a
hundred years. The first ones were steam
powered and mounted on a crane and used
cables to do the digging. There were at
least 4 types of diggers that mounted on a
crane: a drag line, a shovel, a clam shell
and a back hoe.
Here is a steam powered shovel.





And a much later cable operated backhoe.

I have always wondered where the term "back" originated. Is it as simple as, this was mounted on the back of a machine? It was a back hoe because it was on the back!? Just wondering.

I would say that in combination with the direction of the digging action. Wain-Roy was the first to patent (1947) the rear tractor mounted swinging frame design that became the signature feature of the machine we call the Tractor Loader Backhoe (TLB). So while the didn't invent the front loader or the hydraulic hoe I'd say they did invent the TLB

I am not sure but I have always thought that it is because it pulls the material "back" towards you as opposed to pushing forward and away like UD's photo of the steam operated shovel.

Dean, I agree. Another thing that I notice is the rocks that the truck is backing over. In today's world of excavation it would be up to the excavator operator to keep the rocks cleaned up for the truck. That wouldn't have been possible for the shovel operator so it would have been necessary for the truck driver or a third person to clear the rocks.

According to a friend who has been in the business MANY years & has more of this type of equipment than I knew existed, UD's pic of a backhoe is actually an excavator. Backhoes can only swing side-to-side part way, excavators can swivel completely around. But the digging action is the same, pulling toward the machine.

Yeh,But he is protected cause he has his Hard Hat om.

A little OT but speaking of backhoes,
draglines and such...
This is a piece I wrote on Tractor Talk 13?
years ago about selling an old dragline I
had.
Lightened my load by 13 tons

k, so how about the Stabilizing Apparatus? I suppose the basic model would include Ferguson and NAA.

Lynn, it is probably a regional thing. Here in the Northeast one of those old cable backhoes would never be called an excavator.

Without seeing the entire document you are looking at, I find patent # 2,781,927 (shown on the drawing you posted) is for individually controlled outriggers. So if your backhoe has individually controlled outriggers; you have the stabilizer apparatus shown in your posting, I believe. The drawing is just a bit different than the finished product we are used to seeing.

Wain-Roy did apply for/Patent a stabilizer system in the 1980's which incorporated modifications to the loader to provide more stabilization, than just relying on the bucket set on the ground.

hank's Jim. It was said that the produced design had separate outriggers attached to the frame piece. The frame was added at some point due to the N being weak at the transmission mating. Some early on had broken in half when just mounted to the front axle. Do you have a source for patients older than 1976?

No source beyond doing web searches using patent for and key words.

orning, thought I would give this another poke and see if some fresh eyes have had or seen one of the apparatus in person.

ump, looking over the post again. As for the photos posted of the steam shovels and excavators there was only one backhoe roughly 30 to 40 years newer than the first one invented by Wayne Roy. I had the same interest in the statement and the steam machines I knew had existed 50 years earlier, so I bought the book and checked it out.

Any fresh eyes find this post?
Thanks'

EDIT: A lot of the early loaders I am aware of had single acting lift cylinders. I can chain my Davis 100 lift arms all the way down and curl the bucket to lift the wheels. Don't know if this stabilizer would fit under a loader. Looks like it would save time for commercial use.
