Rudge Whitworth 100 wrench, whats it for?

Recommended Posts

I got this recently and have been trying to identify what vehicle(s) its for. I have been able to determine its for removing the hubs on Rudge Whitworth wire wheels?. but I've only found reference to ones marked 62 and 120. 

thanks,

Bill

Looks the same as the wrench for the 24" Rudge Whitworth wheels on my 1922 Packard 126 except that mine is marked 80 not 100.

Bill , you wrench looks like someone has bent it to fit the next larger size of hub. The opening should form a near perfect 1/2 circle with the pin pointing straight towards the handle.

100 means 100 mm (approximately 4 inches) I presume.

Rudge 100's aren't very common. Only some of the most expensive cars used them; some RR Silver Ghosts, the big Mercedes, big Peugeots. I don't know what US cars used Rudge 100.

Thanks for that info. 👍 Yup it does seem uncommon, particularly in the US, which makes it intriguing. as to it possibly being bent or modified, it    seems to be about 150mm across , and does seem pretty much round. but I'm guessing the 100 may mean a thread diameter, rather than overall?. 20190412_162443.thumb.jpg.a139816eaf17c771047dddf9084b29d4.jpg20190412_162641.thumb.jpg.4974c3fc0e0263943369d1348ee800f3.jpg

My early 20th century tool catalog calls these "spanners" not wrenches.   Funny the Brits call open and box end wrenches spanners.  Two countries separated by a common language.

Yes, I just found posts where they are referred to as C- spanners.  makes sense..  I got it in a box of old wrenches though.😁

We call them "C" spanners here in Australia, I called it a wrench because it a US based forum.  One of many different car related names.

Yeah, and I called it a wrench to begin with, which may not be correct. actually I've heard  people  call wrenches spanners here occasionally, but not often.

The only wrench we have is the pipe wrench. The rest are spanners.

Here in the colony's what makes this thing a "spanner" is the little button inside the far end.

Like the thing you use to raise or lower your adjustable shock collars.

 

Q = So how does Spinney put his boot under his bonnet ?

 

Just asking ?

The bonnet is at the front. The boot is at the back. I would have to stand the car on end to put the boot under the bonnet. Or just wave my booted foot under the car.:lol:

Another that gets people going on this side of the world is the different uses of the word hood. 

 

To most on this side of the Pacific- mainly because of our mainly British heritage, and the fact that post WW2 British cars dominated our market - it is the convertible top.

Yup while it makes total sense calling a convertible top a hood, its much like the hood on a jacket, to me a hood is an engine cover 😊 at least on front engine vehicles.

I knew that !

Having grown up working @ a Morris Minor / MG /Jag dealership.

Though I really loved driving the boss's Singer convertible with the hood down.

It most likely was used as a pry

 Maybe, it is a perfect half circle pretty much though, so I think the first photo may just make it look bent?. I probably didn't hold the camera straight. I found a round item about the same size, and posted a photo of it along side. as to being resized, it measures around 150mm across, but am not sure what a 100 wrench/spanner is supposed to measure.

Unfortunately that 100 mm designation does not refer to the size of the wrench opening like a conventional tool size does. It means that it fits the lock ring for what Rudge - Whitworth designates a 100 mm hub.  The opening of the wrench is definitely larger than 100 mm as you state and it should be. You need to find someone with a 100 mm lock nut and see if your wrench fits correctly or needs to be carefully reshaped. At the very least the end with the engagement pin looks to be bent outward. As I mentioned before the pin should point directly at the handle.

 You probably know this already but there are two wrenches supplied. The C- spanner you have for the lock ring . And a somewhat similar but quite a bit smaller box end wrench to fit the octagon on the center cap. The center need not be removed to change a wheel. Only to service front wheel bearings , etc. 

 The wrenches in general are reasonably valuable, but some sizes are comparatively common, in greater demand and probably command higher prices. The more uncommon sizes are probably a bit cheaper as there are fewer people looking for them. There are repro ones out there. Possibly superior in function but lazer cut from plate rather than a forging so not the same appearance at all. If memory serves me correctly I think they are around $250.00 each so I would think a decent original is at least in the same range.

Very good information, thanks Greg. yes I see in the photo above David posted how the ring is separate from the wheel nut.  on the second picture I posted above with it held against something round, does the pin area still look bent? it looks to me it could be slightly, yet it seems to fit the circle perfectly. yeah I saw some other similar ones for sale for about that price. makes sense with them being rather uncommon. this one came close to ending up in the dump or scrapped, no one knew what it was..I didn't either but thought it looked interesting.

I'm pretty sure L head Mercers use a Rudge 80 (same as a Packard), Cadillac -I don't know what size, although I'd like to find out. Crane-Simplex is another possibility, although I'm only guessing now.
